mesna and Sarcoma--Ewing

In high-grade musculoskeletal sarcomas, adjuvant chemotherapy is often performed to prevent distant metastases. The efficacy of chemotherapy varies according to the histological type of sarcoma. Prognoses are poor in patients with osteosarcoma, Ewing's sarcoma, or rhabdomyosarcoma, when surgery alone is performed. However, because these sarcomas are chemosensitive, their prognoses are improved with adjuvant chemotherapy. On the other hand, the efficacy of chemotherapy is not statistically demonstrated in non-round cell sarcomas, e. g., malignant fibrous histiocytoma. Nowadays, several kinds of antitumor agents are usually used for adjuvant chemotherapy, and many authors have reported various kinds of regimens and their clinical results. Commonly used drugs include adriamycin, ifosfamide, cisplatin, methotrexate, cyclophosphamide, dacarbazine, vincristine, and actinomycin-D. Recently, high-dose chemotherapy combined with autologous peripheral blood or bone marrow stem cell transplantation has been begun in patients who do not respond to standard chemotherapy, and a better prognosis is expected.

Influence of age and sex on chemotherapy-related toxicity was evaluated in children (3-9 years), adolescents (10-17 years), and adults (up to 40 years) with localized Ewing sarcoma (ES) enrolled in the ISG/SSG III protocol. Treatment was based on vincristine, doxorubicin, cyclophosphamide, ifosfamide, dactinomycin, and etoposide. High-dose chemotherapy with busulfan and melphalan was given in poor responder patients. The analysis was based on 2191 courses of standard chemotherapy and 230 patients. A lower risk of G4 leukopenia and thrombocytopenia, hospitalization, febrile neutropenia, and red blood cell (RBC) transfusions was observed in males. Use of granulocyte colony-stimulating factor (G-CSF) was more frequent in adults, while children more often received RBC transfusions. A significant correlation between sex and chemotherapy-related toxicity was observed in the study, whereas no significant differences in terms of bone marrow toxicity can be expected according to patient age. Further studies should analyse the role of pharmacokinetics, pharmacogenomics, and clinical characteristics.

Patients with locally advanced or metastatic/recurrent soft tissue and Ewing's sarcoma (EWS) have few treatment options. The purpose of our phase II study was to assess the feasibility, safety and efficacy of tandem high-dose chemotherapy (HDCT) followed by autologous stem cell transplantation (ASCT) in such patients.. Thirteen patients were enrolled onto this study. The first cycle of HDCT consisted of doxorubicin (150 mg/m(2)) and ifosfamide (14 g/m(2)) mixed with mesna (14 g/m(2)), while the second cycle consisted of melphalan (150 mg/m(2)) and cisplatin (200 mg/m(2)).. Eleven out of 13 patients were able to complete both cycles of HDCT. No treatment-related mortality occurred and grade 3 or 4 toxicity was clinically tolerable. The 5-year progression-free survival (PFS) and overall survival (OS) for all patients was 23% (confidence interval, CI: 0-46%) and 31% (CI: 14-70%), respectively. Out of the four patients still alive, two had EWS and measurable disease at the time of ASCT and achieved a complete remission, remaining progression free 126 and 155 months after ASCT.. Our study demonstrates the feasibility and safety of tandem HDCT in patients with high-risk or metastatic/recurrent sarcoma, with some patients achieving long-term PFS and OS.

Previous WR-2721 human pharmacokinetic studies were limited to plasma levels in patients receiving platinum-based compounds, and none includes the effects of WR-2721 on endogenous thiols. In the present study (Pediatric Oncology Group study no. 9457), we measured the levels of WR-2721, its active metabolites, as well as cysteine and glutathione in whole blood, plasma, and blood cells in patients receiving high-dose alkylating agents with mesna.. WR-2721 was administered (15 min intravenous infusion of 825 mg/m(2) per dose x2) to five patients with metastatic Ewing's sarcoma receiving ifosfamide and cyclophosphamide with mesna. Intracellular and extracellular blood thiols were labeled with monobromobimane (mBBr) at the time of collection, and the low molecular weight (LMW) thiols were subsequently separated by HPLC and detected by fluorescence.. The active metabolite of the drug, WR-1065, peaked at 100 microM in plasma and blood cells at the end of WR-2721 infusion and decayed with a rapid initial half-life. Detectable levels of WR-1065 and its LMW disulfides were present in plasma and blood cells at approximately 1 h after the WR-2721 infusion. By the end of the first WR-2721 infusion (prior to mesna infusion), the mean cysteine level more than doubled and the mean Cys-SS-LMW (cystine and the mixed LMW disulfides) level decreased by approximately 50% in both plasma and blood cells. In four of five patients, reduced glutathione levels in blood cells increased by the end of the first WR-2721 infusions, the average increment being approximately 36%.. (1) WR-1065 is rapidly formed from WR-2721 and equilibrates between plasma and blood cells; (2) WR-1065 decays in plasma and blood cells with similar rapid initial half-lives of approximately 16 min; (3) WR-2721 treatment increases cysteine in plasma and blood cells, an effect similar to that of mesna; (4) WR-2721 treatment appears to increase glutathione levels in blood cells; (5) Mesna does not have a substantial effect on the fate of WR-2721 in patients.

Ewing's sarcomas, osteosarcomas, and rhabdomyosarcomas are significantly more responsive to chemotherapy than other sarcomas. Adjuvant chemotherapy is used routinely based on data from randomized trials. Although a percentage of children with locally advanced or metastatic tumors remain curable, few data exist regarding the tumor's natural history or response and survival in adults.. This Phase II study evaluated doxorubicin, dacarbazine, ifosfamide, and mesna (MAID) in adults with inoperable or metastatic Ewing's sarcoma, rhabdomyosarcoma, or osteosarcoma.. Between 1987-1991, 81 patients were entered; 69 patients were eligible. One patient died of neutropenic infection. Ten patients (14%) responded completely and 34 patients (49%) had a complete or partial response. Response rates were significantly higher for patients with Ewing's sarcoma and rhabdomyosarcoma than for those with osteosarcoma (77%, 64%, and 26%, respectively; P < 0.005). Although there were no significant differences in progression free survival by histology, survival for patients with Ewing's sarcoma was significantly longer than for patients with osteosarcoma (P = 0.004.) At the time of last follow-up, 7 patients (10%) were alive without progression: 3 with Ewing's sarcoma, 1 with osteosarcoma, and 3 with rhabdomyosarcoma.. MAID chemotherapy is an active regimen in adults with advanced or metastatic Ewing's sarcoma and rhabdomyosarcoma. Although there was no direct comparison with a doxorubicin and cisplatin-based regimen, the response rate and survival in patients with osteosarcoma suggest that doxorubicin and cisplatin-based chemotherapy would remain the accepted initial chemotherapy regimen. For patients with rhabdomyosarcoma and Ewing's sarcoma, 10-20% of patients remained disease free at 5 years.

The outcome of Ewing's sarcoma depends on the anatomical site of the tumor. Studies conducted in high-risk patients are limited. We evaluated the outcome of high-risk Ewing's sarcoma patients that received long-term treatment protocol. Twenty-five patients (22 males, 3 females) with poor prognostic features were treated according to long-term Ewing's sarcoma protocol. Central-axis localization, inadequacy or unavailability of surgical resection, older than 15 years of age, are accepted as high-risk factors. The median age of patients was 23 years (range, 18-55). The tumor localization was pelvis (9), femur (1), tibia (1), fibula (1), maxilla (1), clavicle (1), vertebrae (5), metatarse (1), and ribs (5). Neoadjuvant chemotherapy was applied between weeks 0 and 6, local therapy on week 9, and adjuvant maintenance chemotherapy between weeks 11 and 41. All patients received neoadjuvant and adjuvant maintenance chemotherapy. Local therapy consisted of radiotherapy (32%), surgery alone (12%), or surgery and radiotherapy (56%). The median total treatment period was 10 months. The median follow-up was 25 months (range, 7-89). Three-year cumulative OS and DFS rates were 43% (95% CI, 28.5-57.85) and 40% (95% CI 23.63-52.19), respectively. The most common grade III/IV toxicities observed during the treatment protocol were neutropenia (16%) and gastrointestinal toxicities (16%). Our study indicated that long-term multiagent combination chemotherapy may result in better outcome in adult high-risk patients undergoing adequate surgical resection of the tumor and local radiotherapy. Further randomized studies are needed to assess the efficacy of this treatment protocol in patients with adequate surgical margins.

The role of tandem high-dose chemotherapy (HDC) with autologous peripheral hematopoietic progenitor cell rescue (APHPCR) in patients with Ewing Family Tumors (EFT) is controversial. We initiated treatment for eight consecutive patients with high-risk EFT with HDC and APHPCR from 1992 to 2003. There were no treatment related deaths. Four patients remain in complete remission, including three who did not undergo local therapy to bone at either the primary or metastatic sites. Our experience has shown that treatment of EFT patients with tandem HDC with APHPCR may benefit a subgroup of high-risk patients in whom optimal local therapy is not possible.

Ewing sarcoma is a relatively uncommon malignant bone neoplasm that usually occurs in children and young adults and involves the major long bones, pelvis, and ribs. Primary diaphragmatic Ewing sarcoma is extremely rare. To the best of our knowledge, only three cases of primary Ewing sarcoma of the diaphragm have been reported. A 12-year-old girl presented spontaneous occurrences of the right hemothorax. After drainage, a roentgenogram film, computed tomography, ultrasonography, and magnetic resonance image showed a giant mass on the right diaphragm. Primary diaphragmatic tumor was resected totally by right posterolateral thoracotomy, and histologically, an extraskeletal Ewing sarcoma was identified. The patient received adjuvant radio-chemotherapy, and there was no evidence of disease 10 months after the operation. Although extremely rare, extraskeletal Ewing sarcoma should be kept in mind in the differential diagnosis of diaphragmatic soft tissue tumors.

To examine the feasibility, tolerability, and toxicity of an intensified induction regimen (vincristine, ifosfamide, doxorubicin, and etoposide [VIDE]) in patients with newly diagnosed Ewing's family of tumors (EFT); to assess ability to maintain dose-intensity, and predictability of peripheral-blood stem cell mobilization.. Thirty patients were treated with vincristine 1.4 mg/m2 (maximum 2 mg) on day 1, doxorubicin 20 mg/m2, ifosfamide 3 g/m2 plus mesna and etoposide 150 mg/m2 on days 1 to 3. Cycles were given every 21 days for up to six cycles.. One-hundred and seventy cycles of VIDE were given. The median treatment interval was 21 days (21 to 42) and nadir count: hemoglobin 8.3 (6.3 to 11.9), neutrophils 0.045 (0.0 to 2.1), and platelets 45 (3 to 343). There were 96 episodes of infection requiring hospitalization (56%). Growth factor support reduced infectious complications by 34%. Etoposide dose was reduced, or omitted, in 24% of cycles. Four patients did not complete six cycles due to unacceptable toxicity and one patient progressed on treatment. Twenty patients underwent peripheral-blood stem cell harvesting, 15 after cycle 3, and five after cycle 4. Median CD34+ yield was 4.6 x 106/kg per patient (1.8 to 14.5). Overall response to treatment, measured in 24 patients, was 88%. Seven of 11 patients undergoing surgery achieved greater than 90% necrosis of tumor (64%).. VIDE is an effective induction regimen with substantial but acceptable toxicity that allows predictable mobilization of stem cells. Maintenance of dose-intensity is feasible in the majority of patients. Growth factors play a role in maintaining dose-intensity and reduce infectious complications.

Ewing's Sarcoma (ES) is a malignant tumor, which arises primarily in children. Most commonly found in the long bones and pelvis, it rarely is found in the bones of the face. This is a report of ES of the mandible in a nine-year-old Caucasian female. Treatment for this malignancy included an incisional biopsy, chemotherapy and radiotherapy protocol to the involved area in accordance with St. Christopher's Hospital and the Children's Hospital of Philadelphia. The patient is currently disease-free and has been for approximately five years.

To increase the dose intensity (DI) of chemotherapy for pediatric patients with metastatic sarcomas, including the Ewing sarcoma family of tumors (ESFT) and rhabdomyosarcoma (RMS), the authors tested the feasibility of an intensive regimen supported by granulocyte-colony stimulating factor (G-CSF) and peripheral blood stem cells (PBSC).. Twenty-three children and adolescents with metastatic sarcomas received vincristine, doxorubicin, cyclophosphamide, ifosfamide, sodium mercaptoethanesulfonate (mensa), and etoposide (VACIME) chemotherapy, consisting of 8 courses of vincristine 2 mg/m(2) on Day 0, doxorubicin 37.5 mg/m(2) per day on Days 0-1, cyclophosphamide 360 mg/m(2) per day on Days 0-4, ifosfamide 1800 mg/m(2) per day on Days 0-4, mesna 2400 mg/m(2) per day, and etoposide 100 mg/m(2) per day on Days 0-4. Doxorubicin was omitted in Courses 7 and 8. G-CSF was given after each course of therapy. Courses of therapy were repeated every 21 days or as soon as hematopoietic recovery permitted. PBSC were collected twice: first, after Course 2 (infused after Courses 3 and 4) and, second, after Course 4 (infused after Courses 5 and 6). Surgical resection followed Course 6, and radiotherapy followed Course 8.. PBSC collections were adequate in 91% of all harvests. The mean DI was 82% (standard deviation, 14%) of the intended DI, which was greater than historic data without PBSC support. Seventeen patients (74%) achieved a complete response (CR), 12 patients with chemotherapy alone and 5 more patients after undergoing surgical resection. Fifteen patients developed progressive disease, with a 2-year event free survival (EFS) rate of 39% (95% confidence interval, 19-59%). Hematopoietic toxicity was severe and cumulative, although it was less than that seen previously without PBSC support.. PBSC-supported multicycle chemotherapy is a feasible method to increase chemotherapy DI for pediatric patients with metastatic sarcomas. Although the CR rate compared favorably with previously reported response rates, the 2-year EFS rate was similar to that achieved with other intensive regimens.

The Pediatric Oncology Group study for metastatic Ewing's sarcoma used amifostine and mesna with the alkylating agents. To determine the fate of combined drug thiols, we measured thiol levels in plasma, red blood cells (RBC), and peripheral blood mononuclear cells (PBMC) of four patients. We also conducted analogous measurements on two patients who received mesna alone and a volunteer's blood following in vitro treatment. Thiols were labeled with monobromobimane, separated on high-pressure liquid chromatography, and detected by fluorescence. Incubation of a volunteer's blood with mesna, WR-1065, or both revealed that cellular uptake of total reducible drug was approximately 10% of plasma level for mesna but approximately 60% for WR-1065. Cellular drugs were mainly the thiol form, whereas half of the plasma drugs were disulfides. Combined incubation with both thiols did not change the extent or form of uptake. WR-1065 and mesna prevented glutathione depletion by 4-hydroperoxycyclophosphamide. Results from patients were similar. WR-1065 and mesna appeared in the cells by the end of the drug infusions, although WR-1065 uptake was more efficient than mesna. The concentration-time profiles of mesna in RBC paralleled those in plasma. Amifostine administration during mesna infusion caused transient increase in mesna levels. Both agents increased blood cysteine and decreased total reducible cysteine. Mesna alone and mesna plus amifostine prevented cellular glutathione depletion. In conclusion, mesna is imported by RBC and PBMC, but less efficiently than WR-1065. When present at equal levels, these thiols do not influence each other's uptake. Adequate dosing of either drug is necessary for protecting the cells from toxic effects of alkylating agents.

Ewing's sarcoma of the pelvic bones was diagnosed in a 21-year childbearing woman, raising major medical and ethical problems. The diagnostic and therapeutic approaches during the sixth month of gestation were tailored in order to cure the patient and avoid unnecessary toxicity to the fetus. Ancillary tests included ultrasound and MRI studies of the pelvis. Ifosfamide and adriamycin, premedicated by granisetron, were administered during gestation, and were found to be safe. Cesarean section was the preferred way of delivery since the tumor involved the pelvic bones. The outcome was a disease-free patient and a small healthy baby who is now two years of age.

Peripheral blood stem cell support allows dose intensification of multiple cycle chemotherapy for metastatic tumors, including pediatric sarcomas. The VACIME protocol (vincristine, adriamycin, cyclophosphamide, ifosfamide, mesna and etoposide) utilizes peripheral blood stem cells (PBSC) collected following the treatment cycle as support for subsequent dose- and time-intensive chemotherapy. A critical assumption is that PBSC collected in this manner will be purged of residual tumor cells in vivo. We tested this assumption using sensitive reverse-transcriptase polymerase chain reaction (RT-PCR) to assess the presence of the characteristic translocations of the Ewing's sarcoma family of tumors (ESFT) and alveolar rhabdomyosarcoma (ARMS), t(11;22), and t(2;13), respectively. We used RT-PCR to evaluate 122 samples of peripheral blood (PB), bone marrow (BM) and PBSC collected from 12 pediatric patients with metastatic ESFT and ARMS. The samples included pre-therapy BM and PB, as well as BM, PB, and PBSC collections at various times in the VACIME treatment course. Molecular evidence of tumor contamination was detected in 1/40 PBSC collections from 12 patients. In all patients, we documented clearance of disease by RT-PCR in peripheral blood and bone marrow by week 9 of the VACIME protocol. In vivo purging in combination with the intensive VACIME regime appears to be effective in removing tumor cells from PBSC, bone marrow, and peripheral blood as detected by RT-PCR.

From January 1990 to December 1995 we treated 35 patients (pts) with bone and soft tissue sarcoma with ifosfamide (IFM). Sixteen patients had measurable metastatic pulmonary lesion and 9 had primary lesion. Histology of the tumor included osteosarcoma in 13 pts, Ewing sarcoma in 5 pts, malignant fibrous histiocytoma of bone in 2 pts, synovial sarcoma in 7pts, primitive neuroectodermal tumor in 2 pts, and other in 7 pts. The IFM at the dose of 12-18g/m2 (mean 15. 4g/m2) for 5 to 8 days continuous infusion was administered to patients in each treatment course. The uroprotector, mesna, was also given concomitantly in 60-100% dose of IFM. Eighteen pts received one course of IFM treatment. Other pts received 2 to 8 courses of IFM treatment at three to four week intervals. The overall response rate was 40% (PR in 14 pts, NC in 18 pts, and PD in 3 pts). The response rate of 13 pts with osteosarcoma was 54% (PR in 7 pts) and 30% in 15 pts with soft tissue sarcoma (PR in 5 pts).

Ewing's sarcoma and primitive neuroectodermal tumour (ES/PNET) are rare, limiting opportunities for therapy studies in adults. Chemotherapy regimens adapted from paediatric studies are often used for adults but concerns about poor outcome and treatment toxicity may adversely affect drug dose intensity. We present our experience using a paediatric protocol at full dose.. Records of 34 patients with ES/PNET who received the IVAD chemotherapy regimens were reviewed. Received drug dose intensity, toxicity and survival data were collected.. Received dose intensity in 30 evaluable patients was 0.92 compared to the standard IVAD schedule. Myelosuppression was the major toxicity, 83% of patients experienced grade 4 neutropenia. There was no major renal or cardiac toxicity. In patients without metastases at presentation, five-year overall survival was 63% and progression free survival was 39%. Tumour burden at presentation was statistically significantly associated with survival (P = 0.002). The five-year survival rate of 80% in patients presenting with low volume non metastatic disease was equivalent to published paediatric series.. Although the IVAD chemotherapy regimens are myelotoxic in adults, they can be given safely. We recommend that adults with ES/PNET should be included in current multicentre, multidisciplinary treatment studies directed at children.

The objective of this study was to determine the tolerance and toxicities of high-dose cyclophosphamide (CPA) at 7 g/m2 given in four fractions over 8 h in children with advanced solid tumors.. Twenty children aged 1 1/2-19 years (median, 12 years) received 24 courses of high-dose CPA at 7 g/m2 for the treatment of advanced malignant solid tumor. CPA was given in four 1-h infusions of 1.75 g/m2 each, with 1 h of rest between each dose. MESNA was used as a uroprotective agent and was continued for 24 h after the final dose of CPA. With only one exception, all patients were discharged at the end of MESNA infusion and received granulocyte colony-stimulating factor, prophylactic ciprofloxacin, and co-trimoxazole.. Severe but transient myelosuppression was observed. The median time to neutrophil and platelet recovery was 17 and 19 days, respectively. Fever developed after 13 of the 24 courses, and hospitalization was required. Extramedullary toxicities were mild. No patient showed cardiomyopathy or hemorrhagic cystitis. Forty-six percent of the courses were managed entirely on an outpatient basis. Objective tumor response was seen in five patients.. CPA at 7 g/m2 is well tolerated by children with advanced malignancies and should be considered in earlier phases of antineoplastic therapy.

Fifty patients with histologically confirmed advanced malignancies were treated with ifosfamide and mesna plus other cytostatics. The other cytostatic drugs added to the treatment regimen were cisplatin (36 pts), etoposide (31 pts) and doxorubicin (20 pts). Among previously untreated patients objective response was documented in 12 of 19 pts with ovarian cancer, 9 of 14 with small cell cancer of the lung and in all 3 pts with Ewing's sarcoma. Among patients with disease refractory to prior cytostatic treatment, objective response was documented in 8 of 9 with testicular cancer, 1 of 3 with high grade lymphoma and 0 of 2 with osteosarcoma. Side-effects due to the combination of ifosfamide plus mesna and other cytostatics were acceptable. No life-threatening or lethal toxicities occurred. Most commonly encountered toxicities were leukopenia (64%), nausea and vomiting (84%), alopecia (63%), CNS toxicity (30%) and renal toxicity (12%).

The German Society of Pediatric Oncology (GPO) has studied the efficacy of high-dose ifosfamide with mesna uroprotection in patients with Ewing's sarcoma. A phase II trial of ifosfamide (IFO) (2 g/m2 per day, days 1-5) in eight patients with recurrent evaluable disease resulted in three partial and two complete responses lasting from 3 to 12 months (median, 6 months). In a second phase II trial in 15 patients, the combination of IFO and cisplatin (20 mg/m2 per day, days 1-5) resulted in 7 partial and 2 complete responses lasting from 3 to 32 months (median, 6 months). Consequently, in 1985 IFO was incorporated into first-line chemotherapy for newly diagnosed patients (replacing cyclophosphamide) and given in combination with vincristine, actinomycin D, and adriamycin (VAIA) in patients considered to be at high risk for relapse. IFO was given at a dose of 3 g/m per day on days 1 and 2 as a 48-h continuous infusion, in combination with actinomycin D (0.5 mg/m2 per day on days 1-3) or Adriamycin (30 mg/m2 per day on days 1 and 2). The study was piloted from March to December 1985 and has been open since January 1986; 37 patients were entered during the pilot phase and 65 have been entered in the ongoing main trial since January 1986. At present, Kaplan-Meier disease-free survival projects that disease-free survival in patients with large primary tumors has improved compared with that reported for the previous CESS 81 trial. The toxicity of the VAIA regimen was comparable with that of the conventional vincristine, actinomycin D, cyclophosphamide, and adriamycin (VACA) regime used in the previous CESS 81 trial.
