taxane and Neutropenia

Neutropenic enterocolitis (NE) must be recognized in patients with fever, neutropenia, and abdominal pain. Classically, NE has been described in patients with hematologic malignancies treated with intensive chemotherapy. Current interest in NE has increased due to recent cases associated with newer, more intensive chemotherapy in solid tumors. This review discusses pathology, clinical presentation, and treatment of NE. Ultrasonography or CT scans are the best radiographic studies to confirm the diagnosis. Management options, including antimicrobial therapy, surgery, and supportive care, are discussed. Chemotherapy incorporating the taxane family of drugs (paclitaxel and docetaxel) associated with NE is also reviewed with observations regarding the earlier onset of the disease in the first weeks following chemotherapy. Even with currently recommended therapy, a high mortality rate, approximating 45%, can occur. Best outcomes for NE rely upon understanding of risks for the condition, prompt empiric therapy with broad-spectrum antimicrobial agents, systemic antifungal therapy, and meticulous attention to supportive care.

The two commercially available taxanes (paclitaxel and docetaxel) are widely employed in standard oncologic practice. Toxicity of the agents includes bone marrow suppression (principally neutropenia), complete alopecia, and hypersensitivity reactions. While both drugs can cause neurotoxicity and myalgias/arthralgias, this is a greater clinical concern with paclitaxel. Docetaxel can be associated with the development of significant fluid retention (e.g., edema, ascites, pleural effusions), the incidence and severity of which appear to be limited by prophylactic treatment with corticosteroids both before and after each treatment. If patients are monitored closely (e.g., for hypersensitivity reactions, bone marrow suppression) the taxanes have a favorable side effect profile, and it is currently uncommon for treatment to be discontinued because of the development of excessive toxicity.

In the randomised, parallel assignment, open-label, phase 3 TH3RESA study, progression-free survival was significantly longer with trastuzumab emtansine versus treatment of physician's choice in previously treated patients with HER2-positive advanced breast cancer. We report results from the final overall survival analysis of the TH3RESA trial.. Eligible patients for the TH3RESA trial were men and women (aged ≥18 years) with centrally confirmed HER2-positive advanced breast cancer previously treated with both trastuzumab and lapatinib (advanced setting) and a taxane (any setting) and with progression on two or more HER2-directed regimens in the advanced setting. Patients had to have an Eastern Cooperative Oncology Group performance status of 0-2, left ventricular ejection fraction of at least 50%, and adequate organ function. Patients were randomly assigned (2:1) by an interactive voice and web response system with permuted block randomisation in blocks of six to receive trastuzumab emtansine (3·6 mg/kg intravenously every 21 days) or treatment of physician's choice administered per local practice. Randomisation was stratified by world region, number of previous regimens for advanced breast cancer, and presence of visceral disease. On Sept 12, 2012, the study protocol was amended to allow patients with disease progression to crossover from treatment of physician's choice to trastuzumab emtansine. The coprimary endpoints for TH3RESA were investigator-assessed progression-free survival and overall survival in the intention-to-treat population. We report results from a preplanned second interim analysis of overall survival, which was planned for when approximately 67% (n=330) of 492 expected deaths had occurred. This study is registered with ClinicalTrials.gov, number NCT01419197.. Between Sept 14, 2011, and Nov 19, 2012, 602 patients were enrolled from 146 centres in 22 countries and randomly assigned to trastuzumab emtansine (n=404) or treatment of physician's choice (n=198). At data cutoff (Feb 13, 2015), 93 (47%) of 198 patients in the physician's choice group had crossed over to trastuzumab emtansine. Overall survival was significantly longer with trastuzumab emtansine versus treatment of physician's choice (median 22·7 months [95% CI 19·4-27·5] vs 15·8 months [13·5-18·7]; hazard ratio 0·68 [95% CI 0·54-0·85]; p=0·0007). As the stopping boundary for overall survival was crossed, this overall survival analysis serves as the final and confirmatory analysis of overall survival and the study was terminated according to the protocol. The incidence of grade 3 or worse adverse events was 161 (40%) of 403 patients in the trastuzumab emtansine group and 87 (47%) of 184 patients in the treatment of physician's choice group. Of the most common grade 3 or worse adverse events (affecting ≥2% of patients in either group), those with a 3% or greater difference in incidence between groups that were more frequent with treatment of physician's choice than with trastuzumab emtansine were diarrhoea (three [1%] of 403 patients in the trastuzumab emtansine group vs eight [4%] of 184 patients in the treatment of physician's choice group), neutropenia (ten [3%] vs 29 [16%]), and febrile neutropenia (one [<1%] vs seven [4%]); whereas those that were more frequent with trastuzumab emtansine were thrombocytopenia (24 [6%] of 403 patients vs five [3%] of 184 patients) and haemorrhage of any type (17 [4%] of 403 vs one [<1%] of 184). Serious adverse events were reported in 102 (25%) of 403 patients in the trastuzumab emtansine group and 41 (22%) of 184 in the physician's choice group. Deaths from adverse events were reported in three patients (2%) in the physician's choice group (of which one was judged to be treatment related) and nine (2%) in the trastuzumab emtansine group (of which three were judged to be treatment related).. In patients who had progressed on two or more HER2-directed regimens, trastuzumab emtansine treatment resulted in a significant improvement in overall survival versus treatment of physician's choice. These data further solidify the role of trastuzumab emtansine in the management of patients with previously treated HER2-positive advanced breast cancer, and validate HER2 as a therapeutic target even after multiple lines of previous therapy..

We conducted a phase II study evaluating safety and efficacy of combination gemcitabine and capecitabine therapy for metastatic breast cancer patients following anthracycline and taxane treatment in Korea.. This was a single-arm, non-randomized phase II study. Patients received 1,000 mg/m(2) gemcitabine intravenously over 30 min on days 1 and 8, and 1,250 mg/m(2) capecitabine orally twice daily on days 1-14 until disease progression or intolerable toxicity occurred. This regimen was repeated every 3 weeks. The primary outcome assessed was overall response rate [ORR, complete response (CR) + partial response (PR) as the best response], and secondary outcomes were progression-free survival (PFS), overall survival (OS), disease control rate (DCR) [maintenance of CR + PR + stable disease (SD) for at least 3 months], drug toxicity, and predictive factors for response to this regimen.. Of 41 patients, the ORR was 39.0% (CR 0%; PR 39.0%), and DCR was 78.0% using this chemotherapy. DCR for 6 and 12 months was 68.3 and 26.8%, respectively. Median PFS was 10.0 months [95% confidence interval (CI) 7.8-12.1], and median OS was 25.1 months (95% CI 18.2-32.1). Prominent toxicities were neutropenia and hand-foot syndrome. Most adverse events were well known, relatively moderate, and reversible. Taxane sensitivity [odds ratio (OR) 0.169; 95% CI 0.034-0.826; P = 0.028] and hepatic metastasis (OR 0.097; 95% CI 0.017-0.559; P = 0.009) were significantly predictive of response to gemcitabine and capecitabine combination.. This study showed reproducible anticancer activity and tolerable toxicity of gemcitabine and capecitabine combination therapy in recurrent or metastatic Korean breast cancer patients previously treated with anthracycline and taxane.

To evaluate the efficacy and safety of docetaxel plus capecitabine (DC) combination as salvage treatment in anthracycline- and taxane-pretreated patients with metastatic breast cancer (MBC).. Patients with MBC who had disease progression after initial chemotherapy with anthracyclines (n = 29; 100 %) and taxanes (n = 11; 37.9 %) were treated with oral capecitabine 950 mg/m(2) twice daily on days 1-14 and docetaxel 75 mg/m(2) on day 1 every 3 weeks. Nineteen (65.5 %) patients received this regimen as second line and 10 (34.5 %) as ≥3rd line of therapy. All patients were evaluable for response and toxicity.. Complete response occurred in two (6.9 %) patients and partial response in eleven (37.9 %) for an overall response rate of 44.8 % (95 % CI 26.7-62.9 %). Eleven women (37.9 %) had stable disease and five (17.2 %) progressive disease. Of the eleven patients previously treated with anthracyclines and taxanes, five (45.5 %) responded to DC combination. The median duration of response was 5.7 months (range 3.4-64.2), the median time to disease progression 9.3 months (range 1.2-58), and the median overall survival 25.5 months. No toxic death occurred. Neutropenia grade 4 occurred in 58.6 % of patients and three of them (10.3 %) developed neutropenic fever. Non-hematological toxicities were manageable with grade 3 hand-foot syndrome occurring in 6.9 % of the patients, fatigue in 3.4 %, and neurotoxicity in 3.4 %.. The DC combination is a valuable regimen as salvage treatment in anthracycline- or anthracycline and taxane-pretreated patients with MBC.

Triple-negative breast cancer (TNBC) is characterized by lack of hormone receptors and HER-2 and shares many features with BRCA1-associated cancer. Preclinical data indicate cisplatin sensitivity, suggesting that these tumors may have defects in the BRCA1 pathway. The carboplatin and gemcitabine (CG) combination is active in unselected anthracycline/taxane pretreated metastatic breast cancer patients, so we carried out a phase II study to evaluate the activity of the CG combination in pretreated metastatic TNBC patients. From 10/2004 to 3/2009 we enrolled 31 patients. Median age was 57 years and 29 patients out of 31 had visceral involvement. The overall response rate (ORR) was 32% (1 complete response /9 partial responses), in addition 5 patients obtained stable disease for >12 weeks. After a median follow-up of 34 months, all patients progressed with a median time to progression of 5.5 months and median overall survival of 11 months. Dose reductions, delays and omissions occurred in 75 (60%), 36 (29%) and 22 (18%) cycles. Grade 3/4 neutropenia occurred in 17 and febrile neutropenia in 4 patients. Ten patients had Grade 3/4 thrombocytopenia. Non hematological toxicities were manageable. The CG combination is a reasonable option for the treatment of metastatic pretreated TNBC patients.

Lenalidomide, a highly potent immunomodulatory derivative of thalidomide, potentiates the action of paclitaxel in vitro against prostate cancer cell lines in co-culture with mononuclear cells. A modular Phase I study of lenalidomide and paclitaxel in men with metastatic castration-resistant prostate cancer (CRPC) was conducted to assess PSA kinetics with lead-in lenalidomide and the feasibility of the combination.. Men with metastatic CRPC with prior taxane chemotherapy were planned for single-agent "lead-in" lenalidomide for 21/28 days at dose-levels: -1 (5 mg), 0 (10 mg), +1 (15 mg), +2 (20 mg), +3 (25 mg); followed by lenalidomide at the same dose and schedule in combination with weekly intravenous paclitaxel 100 mg/m(2) over 3 h on days 1, 8, 15 every 28 days utilizing a 3 + 3 dose-escalation design.. Dose-limiting toxicity was observed in 4/6 patients with first-cycle combination therapy at the 10 mg dose-level and 3/6 patients at the 5 mg dose-level of lenalidomide, respectively. These included Grade 3 neutropenia precluding planned paclitaxel therapy (n = 3), grade 3 gastrointestinal toxicity (n = 2), chest pain (n = 1) and pulmonary embolism (n = 1). With lead-in lenalidomide, two patients with lymph-node dominant CRPC had a PSA-decline and regression in lymph node disease, respectively. Two of seven evaluable patients had PSA declines by 50% with combination therapy. Progression-free survival was 13 weeks (range 4-35 weeks).. The high dose-limiting toxicity rates observed with lenalidomide and weekly paclitaxel require exploration of alternate dose-schedules of the combination in the second-line setting of CRPC. These early observations suggest distinctive toxicity and efficacy outcomes from thalidomide in combination with paclitaxel.

Treatment options are limited for patients with refractory metastatic breast cancer (MBC). Larotaxel (XRP9881) is a novel taxoid with preclinical activity against taxane-resistant breast cancer. The current phase II trial of larotaxel was conducted in women with taxane-treated MBC.. Patients were stratified by response to prior taxane therapy (resistant or nonresistant). Larotaxel 90 mg/m(2) was administered as a 1-h infusion every 3 weeks. Patients were evaluated for tumor response every two cycles. A blinded external response review committee determined the overall response rate (ORR), duration of response (DOR), and time to progression (TtP) of the disease. Median survival time (MST) and safety were also evaluated.. One hundred and thirty patients were treated. In the nonresistant group, the ORR was 42%; median DOR 5.3 months; median TtP 5.4 months; and MST 22.6 months. In the resistant group, the ORR was 19%; median DOR 5.0 months; median TtP 1.6 months; and MST 9.8 months. The most common grade 3/4 adverse events were neutropenia (82%), fatigue (15%), diarrhea (12%), febrile neutropenia (9%), neutropenic infection (8%), and sensory neuropathy (7%).. Larotaxel has good activity, manageable toxicity, and a favorable therapeutic index in women with taxane-pretreated MBC.

Treatment options in patients with recurrent non-small cell lung cancer (NSCLC) remain limited as a result of poor activity of most agents after failure of platinum-based therapy. In the present phase I-II study, we evaluated the feasibility and efficacy of bi-weekly gemcitabine (GEM) + irinotecan (CPT-11) in patients with relapsed NSCLC.. Patients with advanced NSCLC, WHO-performance status (PS)

To evaluate the single agent activity, pharmacokinetics and tolerability of the novel tubulin targeted agent vinflunine (VFL) (320 mg m(-2) q 21 days) as second-line chemotherapy in patients with metastatic breast carcinoma (MBC). All patients had disease progression after anthracycline/taxane (A/T) therapy. They could have received a nonanthracycline adjuvant treatment and subsequently received a first-line A/T combination for advanced/metastatic disease; or relapsed >6 months after completion of adjuvant A/T therapy and were subsequently treated with the alternative agent; or relapsed within 6 months from an adjuvant A/T combination. Objective response was documented in 18 of 60 patients enrolled (RR: 30% (95% confidence interval (CI): 18.9-43.2%)). Among the responders, seven patients had relapsed during a period of <3 months from taxane-based regimen yielding a RR of 33.3%. The median duration of response was 4.8 months (95% CI: 4.2-7.2), median progression-free survival was 3.7 months (95% CI: 2.8-4.2) and median overall survival was 14.3 months (95% CI: 9.2-19.6). The most frequent adverse event was neutropenia (grade 3 in 28.3% and grade 4 in 36.7% of patients). No febrile neutropenia was observed. Fatigue (grade 3 in 16.7% of patients) and constipation (grade 3 in 11.7% of patients) were also common; these were non-cumulative and manageable permitting achievement of a good relative dose intensity of 93.5%. Vinflunine is an active agent with acceptable tolerance in the management of MBC patients previously treated with (A/T)-based regimens. These encouraging phase II results warrant further investigation of this novel agent in combination with other active agents in this setting or in earlier stages of disease.

Pegylated filgrastim is a new formulation of a neutrophil colony-stimulating factor that has a long circulating half-life, permitting a single dose of filgrastim per cycle of chemotherapy. The pegylated filgrastim is recommended to be administered not less than 24 hours following chemotherapy and not less than 14 days prior to chemotherapy based on the theoretic concern that marrow suppression would be accentuated. This schedule of usage for pegylated filgrastim may compromise its application for weekly chemotherapy schedules. We have treated 80 patients with pegylated filgrastim administered on the same day as chemotherapy; the latter delivered on a weekly schedule. Twenty-four patients had non-small cell lung cancer (NSCLC) and were treated with one of two weekly chemotherapy regimens alternating triplets [AT] taxane, cisplatin, irinotecan alternating with gemcitabine, cisplatin, vinorelbine or alternating doublets [AD] taxane, cisplatin alternating with gemcitabine, vinorelbine; four of these patients also received weekly taxane and carboplatin with concomitant thoracic radiation. A consistent pattern emerged in which leukocytosis was observed at Day 8; median WBC 15,800/uL (range 7,200 to 35,000/uL); at Day 14, the median WBC was 9,300/uL (range 1,100 to 17,400/uL). Pegylated filgrastim can be given safely simultaneously with chemotherapy in weekly chemotherapy schedules. The pegfilgrastim can be administered on an every two week (fortnightly) schedule to maintain a weekly chemotherapy schedule.

Currently, there is no gold standard for the treatment of patients with metastatic breast carcinoma who have experienced failure with anthracyclines and taxanes. A biologic rationale suggests that the mechanism of taxane resistance could be because of an excess of depolymerized tubulin that could enhance sensitivity to vinorelbine. The objective of the study was to assess the tolerance and efficiency of weekly vinorelbine in metastatic breast carcinoma after failure with taxanes.. Patients with measurable disease, a World Health Organization performance status of less than 3 and a life expectancy longer than 3 months were eligible. Persistent taxane-induced neuropathy higher than Grade 1 was an exclusion criterion. The initial planned dose was 30 mg/m(2)/week on an outpatient basis without granulocyte colony-stimulating factor (G-CSF). Neutrophil and platelet counts of 1.0 and 80 g/L, respectively, were required before each new injection; otherwise vinorelbine was delayed for 7 days with a dose reduction of 5 mg/m(2) at the second episode. The dose also was reduced if Grade 3 or 4 toxicity occurred. If the adverse event persisted or if the delay exceeded 14 days between 2 injections given at a dose of 20 mg/m(2), vinorelbine was definitively discontinued.. Between November 1997 and March 1999, 40 patients with a median age of 49 (range, 39-69) were enrolled. All of them had previously received anthracyclines and taxanes. Because of the delays in neutrophil recovery, the median dose intensity did not exceed 22.5 mg/m(2)/week (range, 11.25-30), and the initial planned dose of 30 mg/m(2)/week appeared unfeasible without G-CSF. The starting dose therefore was 25 mg/m(2)/week after the first 6 patients. Neutropenia led to fever in only three patients. Other severe toxicities were Grade 2-3 neuropathy (n = 5), Grade 2-3 ileus (n = 7), Grade 3 anemia (n = 4), and Grade 3 sepsis (n = 1). Objective responses were observed in 10 of 40 patients (25%), 7 of whom had visceral metastases and 4 who were refractory to taxanes (including 2 patients with liver involvement > 50%). The median time to failure was 6 months (range, 4-12) for responding patients. Disease stabilization was achieved in 9 patients (23%) for a median duration of 5 months (range, 4-6). The median survival duration for the whole population was 6 months (range, 2-18+).. Weekly vinorelbine is an active salvage therapy for metastatic breast carcinoma after failure with anthracyclines and taxanes, even in patients with taxane-refractory metastatic breast carcinoma. This confirms that vinorelbine and taxanes are not cross-resistant.

Second-line chemotherapy for patients with nonsmall cell lung carcinoma has been ineffective due to the lack of activity of older agents following platinum-based therapy. This Phase II trial evaluated the feasibility, toxicity, and efficacy of two active new agents, gemcitabine and vinorelbine, used in combination as second-line therapy for patients with nonsmall cell lung carcinoma.. Patients with advanced nonsmall cell lung carcinoma who had progressive disease after previous chemotherapy or combined-modality therapy were eligible for this trial. All patients received vinorelbine 20 mg/m(2) followed by gemcitabine 1000 mg/m(2) on Days 1, 8, and 15 of each 28-day cycle. Patients were reevaluated for a response after two treatment courses: responding patients and those with stable disease received a maximum of six courses. Fifty-five patients were treated between January 1998 and November 1998; 47 patients (85%) had previously received both a taxane and a platinum agent.. Objective responses were seen in 9 of 50 evaluable patients (18%), including 8 partial responses and 1 complete response. Twenty-four additional patients (48%) had either minor response or stable disease. The median time to progression for patients with objective response or stable disease was 5 months. The median survival was 6.5 months with an actuarial 1-year survival of 20%. The treatment was well tolerated with uncommon nonhematologic toxicity and no alopecia. Grade 3 neutropenia and thrombocytopenia occurred in 27% and 22% of patients, respectively, but Grade 4 neutropenia was uncommon (occurring in 9% of patients) and only 4 patients required hospitalization for treatment of neutropenia and fever.. The combination of vinorelbine and gemcitabine is active and well tolerated as second-line therapy for patients with advanced nonsmall cell lung carcinoma. This regimen merits further evaluation as a first-line therapy for patients with this disease.

Available data in the literature comparing different induction chemotherapy (IC) regimens on locoregionally advanced nasopharyngeal carcinoma (NPC) are scarce. The purpose of the present study was to evaluate the outcomes of locoregionally advanced NPC patients who were treated with taxane, cisplatin and 5-fluorouracil (TPF) or cisplatin and 5-fluorouracil (PF) as IC followed by concurrent chemoradiotherapy (CCRT).. In total, 1879 patients with locoregionally advanced NPC treated with IC and CCRT from a prospectively maintained database were included in the present observational study. We compared overall survival (OS), disease-specific survival (DSS), distant metastasis-free survival (DMFS), and locoregional relapse-free survival, using the propensity score method.. In total, 1256 patients received TPF or PF as IC backbone. The TPF group showed significantly better OS (hazard ratio [HR], 0.660; 95% confidence interval [CI] 0.442-0.986; P = 0.042), DSS (HR, 0.624; 95% CI 0.411-0.947; P = 0.027) and DMFS (HR, 0.589; 95% CI 0.406-0.855; P = 0.005) compared with the PF group in multivariable analyses. Propensity score matching identified 294 patients in each cohort and confirmed that TPF was associated with significantly improved 5-year OS (88.1% vs. 80.7%; P = 0.042), DSS (88.5% vs. 80.7%; P = 0.021) and DMFS (87.9% vs. 78.6%; P = 0.012) rates compared with the PF group. There were no significant differences in locoregional relapse-free survival before or after matching.. In our study, IC with the TPF regimen combined with CCRT showed improved long-term survival for the patients with locoregionally advanced NPC compared with the PF regimen. However, a prospective randomized clinical trial to validate these findings is necessary.

After taxane and anthracycline failure, no standard chemotherapy regimen is established in metastatic breast cancer (MBC). Capecitabine and cisplatin (XP) combination shows promising results in gastrointestinal cancer, but there are relatively scarce data in MBC. We reviewed the clinical outcome of XP regimen in anthracycline and taxane resistant, heavily pretreated MBC patients.. Between Jan. 2010 to Feb. 2016, 48 HER2 negative MBC patients who failed anthracycline and taxane based chemotherapy were enrolled. In 43.8% of patients, more than 4 regimens were administrated before XP. Thirty-four patients (70.8%) were hormone receptor (HR) positive MBC. Patients were treated with XP (capecitabine [2000mg/m2 per oral; day 1-14] plus cisplatin [60mg/m2 IV; day 1], every 3 weeks) regimen.. Median progression-free survival (PFS) in total population was 4.33 months (range 1.1~33.57 months). HR positive patients showed trends for superior PFS compared to triple negative breast cancer (TNBC), without statistical significance (6.53 vs. 3.83 months, P = 0.168). In HR positive group, patients receiving 3 or less lines of chemotherapy showed superior PFS compared to others (10.1 vs. 3.0 months, P = 0.039). In multivariate analysis, HR positive patients receiving 3 or less lines of regimens still showed superior PFS (HR = 2.624, 95% CI; 1.071~6.43, P = 0.032). Most common toxicity was grade 3-4 neutropenia, without treatment-related deaths.. XP combination regimen showed clinical benefit with tolerable toxicity in heavily pretreated patients, including HR positive patients. After anthracycline and taxane failure, early administration of XP regimen in selected patients may have improve clinical outcome in breast cancer.

To compare the efficacy and tolerability of taxane and nontaxane therapy in senior adults with chemonaïve metastatic castration-resistant prostate cancer (mCRPC), and examine the effect of patient health status on outcomes.. Between 2009 and 2011, 333 patients aged≥70 years with mCRPC were enrolled in a prospective international registry. Patients were categorized as having received taxane-based or nontaxane therapy, and classified as fit, vulnerable, frail, or terminal, according to investigator judgement or International Society of Geriatric Oncology guidelines. Efficacy measures included overall survival (OS) and progression-free survival. Grade 3/4 toxicities were recorded. Predictors of OS were identified using multivariate Cox regression.. The proportions of fit/vulnerable/frail patients were 65%/14%/17% (International Society of Geriatric Oncology), and 39%/43%/17% (investigator). In single-factor analyses, taxane therapy improved OS (hazard ratio [95%CI] = 0.53 [0.30-0.93]; P = 0.027) and progression-free survival (hazard ratio [95% CI] = 0.55 [0.40-0.76]; P<0.001) vs. nontaxane therapy. Patients with frailty also benefited from taxane therapy (adapted regimen in 52%). In multivariate analysis, taxanes improved OS even with poor prognostic factors present (P = 0.017); age was unrelated to prognosis. Taxane therapy was well tolerated; most common grade 3/4 toxicities (taxane vs. nontaxane) were fatigue (17% vs. 4%), nausea/vomiting (14% vs. 5%) and neutropenia (10% vs. 1%).. The results of this nonrandomized, observational study suggest that first-line taxane therapy may benefit senior adults with mCRPC more than alternative therapies. Treatment decisions should not be based on chronological age.

The purpose of the present study was to prospectively evaluate the efficacy and safety of endostar, a recombinant product of endostatin, combined with taxane-based regimens for HER-2 negative metastatic breast cancer (MBC) patients. Women with ages between 18-70 years with histologically confirmed MBC documented as HER-2-negative were included. Endostar was administered at 7.5 mg/m2, d1-14, q21d and was continued until progressive disease, unacceptable toxicity, consent withdrawal, or completion of 24 months of endostar, whichever came first. Taxane-based chemotherapy was continued until progressive disease, unacceptable toxicity, consent withdrawal, or up to 8 cycles. The primary endpoint was overall response rate (ORR). Fifty-seven patients were recruited. The ORRs for the whole population, first-, second-, and third-line therapy or beyond were 68.4%, 79.3%, 54.5%, and 16.7%, respectively. The median PFS was 10.8 (8.0-12.1) months, yet the median OS was still not attained. For the patients receiving first-, second-, and third-line therapy or beyond, median PFS was 11.9, 7.5, and 7.4 months, respectively (P=0.048). No significant difference in median PFS between hormonal receptor-positive and -negative patients was observed. The most common drug-related grade 3-4 hematologic toxicities were neutropenia (80.7%) and leukopenia (77.2%). Six (10.5%) patients experienced febrile neutropenia. The most frequent drug-related grade 3-4 non-hematologic toxicities were liver dysfunction (10.5%) and peripheral neurotoxicity (8.8%). No treatment-related deaths were reported. We conclude that Endostar combined with taxane-based regimens may be effective and safe for the treatment of HER-2-negative MBC. However, further investigations on its long-term efficacy and toxicity are warranted.

To assess the efficacy of vinorelbine (NVB)-based regimens in patients with metastatic triple negative breast cancer (mTNBC) pretreated with anthracyclines and taxanes.. Clinical data of 48 patients diagnosed and treated for mTNBC between 2004 and 2012 at the Cancer Hospital, Chinese Academy of Medical Sciences (CAMS) were retrospectively analyzed. All patients were pretreated with anthracyclines and at least one taxane in neo-adjuvant, adjuvant or chemotherapy for mTNBC and patients should be having at least one measurable metastatic lesion. Totally, 48 patients were included in this study, of which 21 cases received first-line chemotherapy and 27 cases received second-line chemotherapy. Based on the regimen they received, 22 patients were treated with NVB plus platinum (NP), and 26 patients with NVB plus capecitabine (NX).. After 70 months follow-up, in the total group of patients, the objective response rate was 20.8%, clinical benefit rate was 43.8%, median progression free survival (PFS) was 4.4 months and median overall survival (OS) was 15.5 months. In addition, the ORR was significantly better in the NP arm versus NX arm (33.8% vs.7.7%, P=0.029) as well as PFS was statistically improved in the NP arm than NX arm (5.3 m vs. 3.0 m, P=0.023). Similar trend was observed in the OS, although the difference was not statistically significant (27.7 m vs. 14.8 m, P=0.077). In all, the most frequently reported adverse events were G1/2 gastrointestinal toxicity (68.8%) and neutropenia (62.5%) . No significant difference was observed between the NP arm and NX arm (P>0.05). The percentage of patients who delayed chemotherapy administration in the NP arm and NX arm was 9.1% (n=2), and 3.8% (n=1), respectively.. NVB-based combination chemotherapy demonstrates moderate efficacy in mTNBC patients pretreated with anthracyclines and one taxane with manageable toxicity. NP regimen shows potential superiority over NX regimen, and should be further verified in randomized phase III clinical trial in larger cohort.

To evaluate the efficacy and safety of cisplatin and capecitabine combination (XP) therapy for patients with metastatic triple negative breast cancer (TNBC) progressing after anthracycline and taxane treatment.. Twenty-nine metastatic TNBC patients were prospectively enrolled to receive capecitabine (1, 000 mg/m(2) twice daily on days 1-14) and cisplatin (75 mg/m(2) on day 1) , repeated every 3 weeks.. With a median of 6 cycles of XP, all 29 patients were evaluable for response, including 18 PR (62.1%), 6 SD (20.7%), 5 PD (17.2%) and no CR. The response rate was 62.1%. Patients with earlier stage at diagnosis (stage I to IIIA), longer post-operative disease free survival (>2 years) and less metastatic sites (≤ 3) obtained significantly higher response rate than patients with later stage at diagnosis (stage IIIB to IV), shorter post-operative disease free survival (≤ 2 years) and more metastatic sites (>3). The leading side effects were grade 1/2 gastrointestinal and hematological toxicities. Grade 3/4 toxicities included neutropenia (34.5%), leukocytopenia (31.0%), anemia (6.9%), thrombocytopenia (3.4%), nausea/vomiting (20.7%), stomatitis (3.4%), and hand-foot syndrome (3.4%).. Cisplatin and capecitabine combination therapy is an active and well-tolerated doublet treatment in metastatic TNBC patients progressing after anthracycline and taxane treatments.

Lung carcinoma is the most common malignancy and the leading cause of cancer deaths worldwide. Although clinical factors including age, performance status and stage influence the likelihood of benefit from and tolerability of chemotherapy, the genetic profile of individual patients may be an independent predictor of response and toxicity. The present study aimed to identify pharmacogenetic markers associated with clinical response and toxicity in patients with advanced non-small cell lung cancer (NSCLC) treated primarily with carboplatin and paclitaxel.. Genomic DNA samples from 90 adult male patients diagnosed with stage IIIB/IV NSCLC were genotyped for SNPs in candidate genes of relevance to platinating agents and paclitaxel and analyzed for association with survival and toxicities in univariate and multivariate models.. After adjusting for performance status and stage, SNPs in the drug transporters ABCB1 and ABCC1, as well as within NQO1 were associated with progression-free survival. With respect to hematological and nonhematological toxicities, SNPs in drug transporters (ABCB1 and ABCG2) were associated with thrombocytopenia, nausea and neutropenia, whereas SNPs in the DNA repair pathway genes ERCC4 and XPC were significantly associated with neutropenia and sensory neuropathy, respectively.. Our study evaluated and identified SNPs in key candidate genes in platinating agent and taxane pathways associated with outcome and toxicity in advanced NSCLC. If validated in large prospective studies, these findings might provide opportunities to personalize therapeutic strategies.

An effective salvage chemotherapy for advanced and recurrent non-squamous carcinoma of the uterine cervix has not yet been established. The aim of the present study was to analyze the safety and efficacy of a combination chemotherapy for this disease using taxane, anthracycline, and platinum.. This was a retrospective analysis of advanced and recurrent non-squamous cervical cancers treated at the Osaka University Hospital and the Osaka Medical Center for Cancer and Cardiovascular Diseases during a 10 year study period from 2000 to 2009. Single agent chemotherapies and combination chemotherapies for advanced and recurrent cervical cancer cases of non-squamous histology which were reported in the English literature were also reviewed.. Salvage chemotherapy, using taxane, anthracycline and platinum, was performed for 5 advanced and 14 recurrent cases. Prior to the salvage chemotherapy, 15 (79%) of the 19 patients had already received either radiation or chemotherapy. A complete or partial tumor response was achieved in 8 (42%) of the 19 cases. The response rate for recurrent disease in a previously irradiated field was 40%. The median progression-free survival (PFS) and overall survival (OS) were 8 months (1-108) and 13 months (5-108), respectively. Grade 4 and febrile grade 3 neutropenia was observed in 6 cases (32%), but there was no case in which salvage chemotherapy had to be cancelled due to toxicity. According to previous reports, the cumulative response rate of combination chemotherapy (35%) was significantly higher than that of single agent chemotherapy (17%) (p<0.001). OS tended to be longer in the combination chemotherapy cases (8.7 months to 18 months) than that of single agent chemotherapy cases (7.3+ months to 9.1+ months).. Combination chemotherapy of taxane, anthracycline, and platinum was found to have a survival benefit for advanced and recurrent cervical cancer patients of non-squamous carcinoma histology, with a tolerable toxicity.

The risk of treatment-related death (TRD) and febrile neutropaenia (FN) with adjuvant taxane- based chemotherapy for early breast cancer is unknown in Malaysia despite its widespread usage in recent years. This study aims to determine these rates in patients treated in University Malaya Medical Centre (UMMC).. Patients who were treated with adjuvant taxane-based chemotherapy for early breast cancer stages I, II or III from 2007-2011 in UMMC were identified from our UMMC Breast Cancer Registry. The TRD and FN rates were then determined retrospectively from medical records. TRD was defined as death occurring during or within 30 days of completing chemotherapy as a consequence of the chemotherapy treatment. FN was defined as an oral temperature >38.5°C or two consecutive readings of >38.0°C for 2 hours and an absolute neutrophil count <0.5x109/L, or expected to fall below 0.5x109/L.. A total of 622 patients received adjuvant chemotherapy during this period. Of these patients 209 (33.6%) received taxane-based chemotherapy. 4 taxane-based regimens were used namely the FEC-D, TC, TAC and AC-PCX regimens. The commonest regimen employed was the FEC-D regimen accounting for 79.9% of the patients. The FN rate was 10% and there was no TRD.. Adjuvant taxane-based chemotherapy in UMMC for early breast cancer has a FN rate of 10%. Primary prophylactic G-CSF should be considered for patients with any additional risk factor for FN.

In flat-rate reimbursement systems, the hospital's own costs should not exceed its revenues. In a cohort of primary breast cancer (pBC) patients, costs and reimbursement for febrile neutropenia (FN) were compared to verify cost coverage.. A prospective, observational study in pBC patients receiving adjuvant anthracycline ± taxane-based chemotherapy calculated the costs per in-patient FN episode. The correlating revenues were retrospectively analyzed from diagnosis-related group (DRG) invoices. The actual costs of the therapies were compared to the individual DRG revenues, and the results are presented from the provider's perspective.. In 50 patients, n = 11 patients were treated for FN as in-patients. The hospital's overall treatment costs were € 18,288, on average (Ø) € 1663 per case (range € 1139-2344); the overall DRG revenues were € 23,593, Ø € 2145 per case (range € 1266-2660). In n = 8 cases, the DRGs were cost covering, and in n = 3 cases, a loss was observed, but overall resulting in a gain of Ø € 482 per case and thus being cost covering for the provider. Inadequate DRG coding (n = 4/11; 36.4%) resulted in a preventable loss of Ø € 1069/case.. The costs of FN treatment vary substantially and DRG reimbursements do not necessarily reflect the provider's costs. Surprisingly, the in-patient treatment of FN here is overall more than cost covering if adequately coded. The main reasons are asymmetrical costs for this FN low-risk pBC group. These results emphasize the importance of correct medical coding to avoid potential losses.
