Toxicity and efficacy of intensive chemotherapy for children with acute lymphoblastic leukemia (ALL) after first bone marrow or extramedullary relapse.
    Pediatric blood & cancer, 2004, Volume: 43, Issue:5

    Approximately 25% of children newly diagnosed with acute lymphoblastic leukemia (ALL) will eventually experience leukemic relapse, with bone marrow being the most common site of recurrence. The ability to achieve a durable second remission is complicated by toxicity and resistant disease. We report a novel combination of chemotherapy for relapsed pediatric ALL.. Thirty pediatric patients with relapsed medullary (n = 18) and extra-medullary (n = 12) ALL were enrolled at three pediatric institutions. Following receipt of induction and the first Block A and Block B of intensification, each patient was evaluated for toxicity, efficacy in achieving remission, and long-term survival. Additionally, minimal residual disease (MRD) detection by multidimensional flow cytometry (MDF) was performed.. During induction, the major non-hematopoeitic toxicities were mucositis (30% of patients) and bacteremia (50% of patients). Two patients (7%) died of toxicity during induction. Toxicity during intensification Block 1A and 1B was markedly reduced. Eight-nine percent of patients with marrow disease achieved a remission following induction and intensification. The event-free survival (EFS) for all patients at 2 and 4 years were 60% (95% CI: 42-78%) and 49% (95% CI: 30-68%), respectively.. This regimen for patients with relapsed ALL was successful in achieving a second remission for the majority of patients with acceptable toxicity.

Stage III and oestrogen receptor negativity are associated with poor prognosis after adjuvant high-dose therapy in high-risk breast cancer.
    British journal of cancer, 1999, Volume: 79, Issue:9-10

    We report on the efficacy and toxicity of a sequential high-dose therapy with peripheral blood stem cell (PBSC) support in 85 patients with high-risk stage II/III breast cancer. There were 71 patients with more than nine tumour-positive axillary lymph nodes. An induction therapy of two cycles of ifosfamide (total dose, 7.5 g m(-2)) and epirubicin (120 mg m(-2)) was given, and PBSC were harvested during G-CSF-supported leucocyte recovery following the second cycle. The PBSC-supported high-dose chemotherapy consisted of two cycles of ifosfamide (total dose, 12,000 mg m(-2)), carboplatin (900 mg m(-2)) and epirubicin (180 mg m(-2)). Patients were autografted with a median number of 3.7 x 10(6) CD34+ cells kg(-1) (range, 1.9-26.5 x 10(6)) resulting in haematological reconstitution within approximately 2 weeks following high-dose therapy. The toxicity was moderate in general, and there was no treatment-related toxic death. Twenty-one patients relapsed between 3 and 30 months following the last cycle of high-dose therapy (median, 11 months). The probability of disease-free and overall survival at 4 years were 60% and 83%, respectively. According to a multivariate analysis, patients with stage II disease had a significantly better probability of disease-free survival (74%) in comparison to patients with stage III disease (36%). The probability of disease-free survival was also significantly better for patients with oestrogen receptor-positive tumours (70%) compared to patients with receptor-negative ones (40%). Bone marrow samples collected from 52 patients after high-dose therapy were examined to evaluate the prognostic relevance of isolated tumour cells. The proportion of patients presenting with tumour cell-positive samples did not change in comparison to that observed before high-dose therapy (65% vs 71%), but a decrease in the incidence and concentration of tumour cells was observed over time after high-dose therapy. This finding was true for patients with relapse and for those in remission, which argues against a prognostic significance of isolated tumour cells in bone marrow. In conclusion, sequential high-dose chemotherapy with PBSC support can be safely administered to patients with high-risk stage II/III breast cancer. Further intensification of the therapy, including the addition of non-cross resistant drugs or immunological approaches such as the use of antibodies against HER-2/NEU, may be envisaged for patients with stage III disease and hormone rec

Radiation therapy for consolidation of metastatic or recurrent sarcomas in children treated with intensive chemotherapy and stem cell rescue. A feasibility study.
    International journal of radiation oncology, biology, physics, 1999, Jun-01, Volume: 44, Issue:3

    To assess the role of consolidative radiation therapy (CRT) in conjunction with myeloablative therapy with or without total body irradiation (TBI) in children and young adults with metastatic or recurrent sarcoma.. Twenty-one pediatric sarcoma patients with metastatic (10) or recurrent (11) disease were entered on a prospective feasibility study of intensive myeloablative therapy with or without TBI. Median patient age was 17.8 years (range, 9.4-24.7 years). Primary histologies included Ewing's (12), PNET (3), and other soft tissue sarcomas (6). Twenty patients received induction chemotherapy. Myeloablative therapy consisted of TBI in 11 patients with either high dose melphalan/etoposide (9) or high dose cytoxan/thiotepa (2). TBI consisted of 12 Gy in 2 Gy fractions delivered twice daily over 3 days. Ten patients received high dose chemotherapy alone, either with thiotepa/carboplatinum/etoposide (8) or cytoxan/carboplatinum (2). Myeloablative therapy was followed by autologous stem cell rescue (ASCR) 24 to 48 hours after completing chemotherapy. Fourteen patients (67%) received CRT either prior to (5) or following (9) myeloablative therapy. Median CRT dose was 37.2 Gy (range, 20-60). Fifty-one disease sites were present prior to myeloablative therapy. Twelve (24%) were bulky (> 8 cm) and 18 (35%) underwent surgical debulking. The median follow-up of surviving patients was 15 months (range, 8-20) with 25% of patients having been followed for more than 20 months.. The 3-year actuarial disease-free (DFS) and overall survival (OS) rates for the entire group were 36% and 27%, respectively. Following myeloablative treatment, responses were: 11 complete, 6 partial, 1 stable, and 3 progressive disease. Sixteen patients (71%) have relapsed. The most common site of relapse was the lung (13). Of the 51 disease sites present prior to myeloablative therapy, 36 sites (71%) were amenable to CRT. Nonamenable sites were: multiple lung metastases (13) and bone marrow (2). Twenty-six amenable sites (51%) received CRT either prior to (14) or following (12) ASCR. Amenable sites treated with CRT had a better 3-year actuarial local control (80 vs 37%) (p = 0.0065) than amenable sites not treated with CRT. Factors associated with improved disease-free survival (DFS) in univariate analysis were induction chemotherapy response (p = 0.002) and extent of surgical resection (p = 0.045). There was a trend toward improved DFS on univariate analysis with the use of TBI as part of myeloablative therapy (p = 0.07). The one factor associated with improved OS on univariate analysis was induction chemotherapy response (p = 0.007). Multivariate analysis revealed that induction chemotherapy response is the only factor that remains significant for DFS (p = 0.032) as well as for OS (p = 0.017). Patients with complete response to induction therapy had 40% probability of survival versus all other patients who had 10% survival (p = 0.05).. Consolidative radiotherapy is feasible in primary metastatic or recurrent pediatric sarcoma patients treated with myeloablative therapy with or without TBI. CRT to sites amenable to irradiation provided an improved 3-year actuarial local control than that seen in sites amenable to CRT that did not undergo radiotherapy. There was a trend for improved DFS with the use of TBI. Improved DFS and OS can be predicted by response to induction therapy. This intensive regimen may improve the cure rate of advanced pediatric sarcomas in select patients.
