mesna and Neoplasm-Metastasis

Metastases from cystosarcoma phyllodes are rare, and treatment generally is ineffective. Four patients were treated with ifosfamide (alone in three and combined with doxorubicin in one). Two patients had complete remissions that lasted 26 and 61+ months. One other patient had a partial response that lasted 13 months. The complete responders were both treated as soon as metastases appeared, when they had only a small volume of disease. This appears to represent a significant improvement on other described regimens for this condition, and further trials of ifosfamide are warranted. Close follow-up of patients at high risk for metastases is suggested.

We undertook a randomized phase II trial to test whether the addition of paclitaxel (Taxol) to the cisplatin and ifosfamide (IP) combination could improve objective response (OR) rate, progression-free survival (PFS) and overall survival (OS) in patients with recurrent or metastatic cancer of the uterine cervix.. One hundred and fifty-three patients were randomly allocated to receive either the IP regimen (ifosfamide 1.5 g/m(2), daily, on days 1-3 and cisplatin 70 mg/m(2) on day 2) or the same combination with the addition of paclitaxel 175 mg/m(2) on day 1 [ifosfamide, paclitaxel and cisplatinum (ITP) regimen]. Cycles were administered every 4 weeks on an outpatient basis.. A modest increase in neurotoxicity was observed with the triplet combination. OR rate was significantly higher in the ITP group (59% versus 33%, P = 0.002). Median PFS was 7.9 and 6.3 months for patients in the ITP and IP arms, respectively (P = 0.023). Median OS was 15.4 months and 13.2 months in the ITP and IP arms, respectively (P = 0.048). In multivariate analysis, the triplet yielded a hazard ratio of 0.70 for relapse or progression (P = 0.046) and 0.75 for death (P = 0.124) compared with the doublet.. The ITP combination merits further investigation in randomized phase III studies.

To improve the prognosis for pediatric patients with metastatic sarcomas, including the Ewing sarcoma family of tumors (ESFT), rhabdomyosarcoma (RMS), and undifferentiated sarcoma (UDS), we tested the feasibility of a brief, intensive regimen of chemotherapy that maximizes dose intensity.. Twenty-four children and adolescents with metastatic sarcomas received VACIME chemotherapy, consisting of eight courses of vincristine 2 mg/m(2) on day 0; doxorubicin 20 mg/m(2)/day on days 0-3; cyclophosphamide 360 mg/m(2)/day on days 0-4; ifosfamide 1,800 mg/m(2)/day on days 0-4; mesna 2,400 mg/m(2)/day; and etoposide 100 mg/m(2)/day on days 0-4. Doxorubicin was omitted in courses 7 and 8. Granulocyte colony-stimulating factor (G-CSF) was used routinely following each course of therapy. Courses of therapy were repeated every 21 days or as soon as hematopoietic recovery and resolution of nonhematopoietic toxicities permitted. Surgical resection followed course 6, and radiotherapy followed the completion of all therapy.. Thirteen patients achieved a complete response (CR) with chemotherapy alone, and seven more achieved a CR following surgical resection after course 6 (overall CR rate 83%). There was one toxic death. Thirteen patients developed progressive disease, with 2- and 4-year event-free survivals (95% confidence interval) of 50% (30-70%) and 45% (25-65%), respectively. Myelosuppression was severe and cumulative, leading to dose reductions and chemotherapy interval delays. Mucositis was the most common nonhematopoietic toxicity.. VACIME chemotherapy was a feasible dose-intensive regimen for pediatric patients with metastatic sarcomas. Cumulative hematopoietic toxicity and severe mucositis limited the delivery of chemotherapy as prescribed. The CR and 2-year event-free survival rates were superior to those of most previously reported regimens.

A prospective trial to evaluate the efficacy and toxicity of ifosfamide (IFX) and vinorelbine (VNB) in patients with prior anthracycline therapy for metastatic breast cancer (MBC) was conducted. At the same time, the scheduling of VNB in order to minimize toxicity of the combination was also evaluated.. Twenty-three patients with MBC who had already received initial chemotherapy with doxorubicin-containing regimens either as adjuvant or as first-line treatment in MBC were entered into the study. IFX 3 g/m(2) and mesna 3 g/m(2) were given in divided doses over 2 days. In 4 patients, VNB was given 25 g/m(2) on days 1 and 3 in 3-h infusion. In 8 patients, VNB was given on days 1 and 8 and in 5 patients VNB was given on days 1 and 15. Thirteen patients had received doxorubicin in adjuvant setting, while 10 patients received doxorubicin as first-line treatment in metastatic disease. Dominant disease sites were soft tissues in 7 patients, visceral in 12 patients, and bone in 4 patients. The median age was 47 years.. Overall objective response was seen in 12/23 patients (52.2%). Four patients achieved complete remission (CR), 8 patients achieved partial remission (PR). The median duration of response was 9 months in responding patients, and the median overall survival duration was 15 months. The major dose-limiting toxicities were neutropenia grade III and IV in 8/17 patients and asthenia grade III and IV in 4 patients.. IFX and VNB is an active combination. Neutropenia and asthenia were most significant when VNB was given on days 1 and 3. In the best-tolerated regimen, VNB was given on days 1 and 8.

Forty-six patients were included in a phase II study to evaluate the response rate and toxicity of a combination of ifosfamide and vinorelbine in metastatic breast cancer patients previously treated with one or more regimens of chemotherapy. Treatment consisted of ifosfamide 1.6 g/m(2) IV days 1-3 (with mesna) and vinorelbine 25 mg/m(2) IV days 1 and 8, every 3 weeks up to 6 cycles. The median age was 55 years (range 40-76), the World Health Organization (WHO) performance status was 0-1 in 93% of the patients and 2 in the remaining 7%. In all, 43% had received two or more previous lines of chemotherapy, and 91% had been treated with anthracyclines. Forty-four patients were evaluable for response, and all patients for toxicity. The overall response rate was 36.4% [95% confidence interval (CI) 22.4-52.2]. Stabilization was observed in 20.4% and progression in 43.2%. The median time to progression was 25 weeks (95% CI 14-36). Median relative dose intensity (=actual received dose intensity/planned dose intensity) was 0.99 for ifosfamide and 0. 80 for vinorelbine. The main toxicity was hematological, with 63% of the patients experiencing grade 3-4 neutropenia. With a moderate toxicity, this is an active regimen that may be taken into consideration in pretreated metastatic breast cancer patients when further chemotherapy is indicated.

The aim of this paper is to evaluate the activity of ifosfamide in previously treated patients with metastatic breast cancer. From June 1991 through November 1992, 29 patients with metastatic breast cancer were treated with single-agent ifosfamide, 2 g/m2 intravenously daily for 5 days, with mesna support. All patients had previously received chemotherapy; all but one had previously received cyclophosphamide. The ifosfamide-mesna regimen was the first-line metastatic regimen in 15 patients, the second-line metastatic regimen in 13 patients, and the third-line metastatic regimen in one patient. Two partial remissions (7%) were observed; both occurred in the first-line metastatic group. The partial remissions were noted in patients who had completed adjuvant cyclophosphamide therapy 60 and 91 months earlier. Both responses were seen in lung metastases. The response durations were 5 and 8 months on continued therapy. The main adverse effects were granulocytopenia, fatigue, nausea, vomiting, and stomatitis. At the dose used in this study, ifosfamide and mesna given without growth-factor support resulted in significant myelosuppression and produced only two partial remissions (7%) in 29 patients. Further study of ifosfamide as an isolated agent in previously treated patients is not warranted.

In vitro data suggest that prolonged exposure to paclitaxel enhances breast cancer cytotoxicity. Our objective in this phase I study was to determine the tolerability of paclitaxel administered by 72-hour continuous intravenous (i.v.) infusion (CIVI) in combination with high-dose cyclophosphamide and granulocyte colony-stimulating factor (G-CSF) in the ambulatory setting to metastatic breast cancer patients.. Paclitaxel was administered over 72 hours by CIVI and cyclophosphamide was given daily by i.v. bolus on days 1, 2, and 3, followed by G-CSF every 21 days. The availability of ambulatory infusion pumps and paclitaxel-compatible tubing permitted outpatient administration.. Fifty-five patients with metastatic breast cancer who had been previously treated with a median of two prior chemotherapy regimens were entered onto the study. Dose-limiting toxicity of grade 4 neutropenia for longer than 5 days and grade 4 thrombocytopenia occurred in three of five patients treated with paclitaxel 160 mg/m2 CIVI and cyclophosphamide 3,300 mg/m2 followed by G-CSF. The maximum-tolerated dose (MTD) was paclitaxel 160 mg/m2 CIVI and cyclophosphamide 2,700 mg/m2 in divided doses with G-CSF. Nonhematologic toxicities were moderate and included diarrhea, mucositis, and arthalgias. Although hemorrhagic cystitis developed in six patients, recurrence was prevented with i.v. and oral mesna, which permitted continued outpatient delivery. One hundred seventy-four cycles were safely administered in the ambulatory setting using infusional pumps and tubing. Objective responses occurred in 23 (one complete and 22 partial) of 42 patients with bidimensionally measurable disease (55%; 95% confidence interval, 38% to 70%), with a response rate of 73% (11 of 15) seen at the highest dose levels.. Paclitaxel by 72-hour CIVI with daily cyclophosphamide followed by G-CSF can be administered safely in the ambulatory setting, has acceptable toxicity, and is an active regimen in the treatment of metastatic breast cancer.

To determine the effectiveness and toxicity of ifosfamide chemotherapy in women with metastatic or recurrent endometrial stromal sarcomas unexposed to other chemotherapy.. In a prospective, multi-institutional phase II study conducted by the Gynecology Oncology Group, the starting dose of ifosfamide was 1.5 g/m2 given daily intravenously (i.v.) for 5 days (reduced to 1.2 g/m2 daily in patients who had previously received radiotherapy). Mesna (2 mercaptoethane sodium sulfonate) was given i.v. immediately and at 4 and 8 hours after the administration of ifosfamide. Each dose of mesna was 20% of the total daily dose of ifosfamide. Patients were treated every 3 weeks if blood counts permitted. Therapy was discontinued if there was progression of the cancer or unacceptable toxicity.. Twenty-two patients were entered into this study. One was excluded from analysis because of the wrong histologic type, leaving 21 evaluable for response and toxicity. Gynecologic Oncology Group grade 3 or 4 granulocytopenia occurred in four patients (19%), and one patient each experienced Gynecologic Oncology Group grade 4 anemia and genitourinary toxicity. Three patients experienced complete tumor responses and four had partial responses, for an overall response rate of 33.3%.. Ifosfamide is active in the therapy of women with chemotherapy-naive metastatic or recurrent endometrial stromal sarcomas.

Twenty patients with locally advanced or metastatic breast cancer were treated with four cycles of ifosfamide/mesna 5 g m-2 and epirubicin 60 mg m-2 every 14 days with granulocyte colony-stimulating factor (G-CSF, Filgrastim). Complete remission occurred in six out of the 20 patients (30%, 95% confidence interval 12-54%) and there were 12 partial responders (60%, 95% confidence interval 37-81%), thus giving an overall response rate of 90% (95% confidence interval 63-97%). Two patients had progressive disease. The median duration of response for those patients with metastatic disease was 7.3 (1.3-20.1+) months. The median survival time for these patients was 15 (5.3-27.9+) months. Of the four patients treated with locally advanced disease three achieved a complete clinical response and one a partial response. Three out of four of these patients subsequently underwent a mastectomy, and in one of these no viable tumour was seen. Our conclusion is that this regimen is excellent palliation for metastatic disease and possibly useful neoadjuvant treatment.

Ifosfamide is an oxazaphosphorine analogue of cyclophosphamide with proven activity in breast cancer but substantial urotoxicity. The introduction of mesna as a uroprotective agent provided a stimulus for reexamination of ifosfamide for therapy of women with metastatic breast cancer. Twenty women with measurable (18 patients) or evaluable (2 patients) disease were entered into a phase II clinical trial of ifosfamide plus mesna as first-line chemotherapy. Ifosfamide was administered i.v. at a dose of 1,800 mg/m2 in 1 L D5W over 2 h on five consecutive days. Mesna was administered i.v. at a dose of 400 mg/m2 over 15 min immediately before and 1 h after ifosfamide, and then every 4 h for three more doses. The last three doses could be given either i.v. or orally. The planned cycle length was 28 days. Three patients (15%), all with measurable disease, achieved a partial response (95% confidence interval: 3 to 38%). Median time to progression was 137 days and median survival was 407 days. Toxicities included cumulative myelosuppression and substantial nausea and emesis. Four patients were removed from treatment because of toxicity alone and a fifth refused further therapy. We conclude that ifosfamide, plus mesna, as given in this protocol has definite but limited antitumor activity and poor tolerability.

Ameloblastoma is generally characterized as a benign tumor originating in odontogenic epithelium. However, few cases of metastatic malignant ameloblastoma have also been reported. Due to the low incidence of malignant ameloblastoma, there is no established treatment regimen. To explore effective treatment for malignant ameloblastoma, we reported this case study.. This report described a case of a 28-year-old malignant ameloblastoma female patient with multiple metastasis (brain and lung).. The patient presented ameloblastoma of the left mandible in 2012. Three years later, local recurrence and brain metastasis was observed during a follow-up examination. Five years later, malignant ameloblastoma was detected by imaging and immunohistochemistry in the bilateral multiple pulmonary nodules and mediastinal lymph nodes.. The patient was initially treated with tumor resection. Three years later after local recurrence and brain metastasis, she was accepted the extensive mandibulectomy supplemented with brain stereotactic body radiotherapy (SBRT). When diagnosed with pulmonary metastasis, the patient received combined chemotherapy regimen of MAID (mesna, adriamycin, ifosfamide and dacarbazine) for 6 cycles.. The efficacy evaluation was partial remission (PR) after the 6 cycles of MAID. The last patient follow-up was July 24th 2018, and no evidence of progression was observed. The progression-free survival (PFS) of the patient was more than 9 months.. Surgical resection is the optimal treatment for locally recurrent ameloblastoma. SBRT may be an effective treatment for unresectable oligometastasis of malignant ameloblastoma. Finally, combined chemotherapy of MAID showed encouraging effects in the management of metastatic malignant ameloblastoma.

Multi-institutional collaborative studies that include large patient populations for the management of retinoblastoma with histopathological risk factors could provide important information for patient management.. To evaluate the implementation of a strategy for the management of nonmetastatic unilateral retinoblastoma in children based on standardized diagnostic and treatment criteria.. This single-arm prospective study applied a strategy based on a single-center experience. The setting was a multicenter study in Latin America (Grupo de America Latina de Oncologia Pediatrica [GALOP]). Participants were children with nonmetastatic unilateral retinoblastoma (staged with the International Retinoblastoma Staging System). The study opened on July 1, 2008, and closed on December 31, 2014. Follow-up was updated until June 30, 2017.. Stage 0 patients (without enucleation) were given conservative therapy without a protocol. Stage I patients (with enucleation and no residual tumor) were divided into a high-risk group (retrolaminar invasion and/or scleral invasion) and a low-risk group (all remaining patients). High-risk children received adjuvant chemotherapy with 4 alternating cycles of regimen 1 (cyclophosphamide [65 mg/kg/d] [plus sodium-2-mercaptoethane sulfonate], idarubicin hydrochloride [10 mg/m2/d], and vincristine sulfate [0.05 mg/kg/d]) and 4 cycles of regimen 2 (carboplatin [500 mg/m2/d, days 1 and 2] and etoposide [100 mg/m2/d, days 1-3]). Low-risk children did not receive adjuvant therapy. Children with buphthalmia received neoadjuvant and adjuvant chemotherapy for a total of 8 cycles.. Probability of event-free survival (extraocular relapse and death from any cause were considered events).. Among 187 children registered in the study, 175 were evaluable (92 [52.5%] female; median age, 22 months; age range, 3-100 months). Forty-two were stage 0 children, 84 were stage I low-risk children, and 42 were stage I high-risk children; there were 7 children in the buphthalmia group. With a median follow-up of 46 months, the 3-year probability of event-free survival was 0.97 (95% CI, 0.94-0.99), and the probability of overall survival was 0.98 (95% CI, 0.94-1.00). Stage 0 patients had no events, stage I low-risk patients had 1 event (orbital relapse treated with second-line therapy), stage I high-risk patients had 2 events (1 central nervous system relapse and 1 death from sepsis), and the buphthalmia group had 1 event (orbital relapse, followed by central nervous relapse and death).. Adjuvant therapy may be effective for high-risk unilateral retinoblastoma but is toxic, and neoadjuvant chemotherapy for buphthalmus appears feasible.

Alveolar soft part sarcoma is a rare malignant tumor with unusual clinical behavior. Treatment of alveolar soft part sarcoma has been difficult to evaluate because of the small numbers of cases seen, but it seemed that although treatment of the primary tumor in alveolar soft part sarcoma often is successful, treatment of metastatic tumors is unsuccessful. A review of outcome after treatment of primary and metastatic disease in the 15 patients in our database with alveolar soft part sarcoma was done in order to evaluate this issue. Nine of 15 patients presented with metastatic disease and one further patient developed metastases. Treatment of primary tumors involved surgical excision in all but one patient and radiation in all patients. Adjuvant chemotherapy was administered to one patient with localized disease and to six patients with metastatic disease. There were no local recurrences. Treatment of metastatic tumors involved chemotherapy in seven patients, metastectomy in three patients, and radiation in two patients. All instances of the metastatic disease either recurred or progressed. Overall survival was 75% at 5 years and 40% at 10 years with a mean survival of 6.5 years, despite the high number of patients with metastatic disease. Current treatment results in good local control of primary tumors, but poor control of metastatic tumors. New approaches to treatment of metastatic alveolar soft part sarcoma must be investigated and applied.. Therapeutic study, Level IV-1 (case series). See the Guidelines for Authors for a complete description of levels of evidence.

Alveolar soft-part sarcoma (ASPS) is a very rare malignant tumor, usually of the extremities, and is seen most often in adolescents and young adults. Surgical excision of the primary and pulmonary metastases has resulted in prolonged survival in some patients, but adjuvant radiation and/or chemotherapy are generally thought to be ineffective. The authors describe a 13-year-old patient with ASPS of an extremity who presented with multiple bilateral pulmonary metastases at diagnosis. Following intensive multiagent chemotherapy, pulmonary metastases showed in vivo evidence of tumor death. The patient has remained disease-free for 10 years following treatment.

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.

Patients with metastatic breast cancer will receive 4-5 cycles of induction chemotherapy on one of the ongoing Medicine Branch protocols. Patients achieving at least a partial response, and who do not have evidence of bone marrow involvement and who do not have metastatic bone disease, will undergo PBSC and bone marrow harvest when hematologic recovery has occurred. Patients who have not achieved a PR, but who are responding to therapy, may be treated with additional cycles of therapy in an attempt to achieve a PR. Such patients will be eligible for transplant if a PR is obtained. 70% of the bone marrow and PBSC will be cryopreserved. The CD34+ subpopulation from the remaining 30% of the bone marrow and PBSC harvest will be obtained using an anti-CD34+ antibody and immunoabsorption column. The bone marrow and peripheral blood CD34 cells will be transduced with a retroviral vector expressing the human MDR-1 cDNA. Patients with positive bone scans or histologic evidence of bone marrow involvement will be excluded from the gene transfer component of the protocol. The MDR-1 transduced CD34 cells will be reinfused along with the non-transduced bone marrow and PBSC into patients following high dose ICE chemotherapy. Serial peripheral blood and bone marrow samples will be obtained to study hematopoietic reconstitution with MDR-1 transduced cells. Patients with residual or progressive disease after ABMT will be treated with taxol or vinblastine. In these relapsed patients, peripheral blood and bone marrow samples will be obtained to study whether chemotherapy amplifies the proportion of hematopoietic cells containing the MDR-1 provirus. We will monitor the nadir blood counts of each patient receiving salvage chemotherapy for evidence of myeloprotection and correlate this data with changes in the mean proviral copy number. Sites of relapsed tumor will be biopsied to test for the presence of the MDR-1 provirus.

Between 1982 and 1986, 38 patients with soft tissue sarcomas were treated with a combination of ADM/DTIC (group A), another 45 (group B) received ADM/IFO between 1986 and 1990. Clinical characteristics were comparable in both groups. Remission rate was 34% in group A and 43% in group B. Duration of remission was 10 months and median survival 13 months in both groups. Toxicity, especially myelotoxicity, was severe without marked differences between both groups. We conclude that adriamycin/DTIC and adriamycin/ifosfamide are both active regimens in metastatic soft tissue sarcomas, nevertheless, overall prognosis remains poor.

Thirty-five patients with a median age of 55 years (range, 28 to 68 years) and a median Karnofsky status of 80% (range, 40% to 100%) were treated with ifosfamide (1.5 g/m2 plus mesna), methotrexate (40 mg/m2), and 5-fluorouracil (600 mg/m2) intravenously (IV) days 1 and 8 at intervals of 4 weeks. Thirty-four patients had received previous chemotherapy, including anthracyclines in 28 patients. All patients were evaluable for response. A partial remission was achieved in six patients (17%), stable disease in 13 patients (37%), and 16 patients (46%) were unresponsive. Median time to progression was 7 months (range, 4 to 13 months) for partial responders, and 4 months for patients with stable disease. Median survival was 9 months for all patients, 13 months for partial responders, 16 months for no change, and 3 months for progressive disease. Toxicity was tolerable, with myelotoxicity being a dose-limiting factor, mainly in heavily pretreated patients. No treatment-related death occurred. In conclusion, this combination is effective and well tolerated. Ifosfamide is suggested for further evaluation in advanced breast cancer.

Fifty-seven patients with advanced malignant tumours were treated with ifosfamide (Holoxan) and mesna (Uromitexan) in our department from November 1979 to December 1984. This series comprised eight cases of soft tissue sarcoma, nine cases of ovarian carcinoma, five cases of non-seminomatous testicular tumour, 11 cases of bronchogenic carcinoma, three cases of renal carcinoma, seven cases of non-Hodgkin's lymphoma, two cases of skeletal fibrosarcoma, two cases of breast carcinoma, one case each of Ewing's tumour, prostatic carcinoma, seminoma, plasma cell tumour, multiple myeloma, malignant teratoma, nasopharyngeal carcinoma, Wilms's tumour, neuroblastoma and mycosis fungoides. Out of these 57 cases, 53 were evaluable. There were five complete remissions and 20 partial remissions, corresponding to a total response rate of 47%. The overall median survival time (MST) of the 53 evaluable patients was 7.5 months. The responders had a longer survival time (MST 10 months) than the non-responders (MST 4.75 months) (p greater than 0.05). Analysis of the results according to sex, age, dosage of ifosfamide and degree of histological differentiation of the tumour cells failed to show any influence of these factors on the therapeutic results. The response rate to ifosfamide found in this study might be related to the histological origin of the tumours and to whether the primary tumours had been resected. The non-seminomatous testicular tumours, non-Hodgkin's lymphomas and ovarian carcinomas showed a high response rate. The response rate was higher in the group in which the primary tumour had been resected (61%) than in the non-resected group (12%) (except the non-Hodgkin's lymphoma). The side-effects of this regimen were moderate. Dyspepsia, nausea, vomiting, myelodepression, dizziness, and alopecia were common. Cystitis could be prevented nearly completely by concomitant administration of mesna, when given correctly, for preventing side-effects of ifosfamide on the urinary system (haemorrhagic cystitis, etc.).

This study describes the prolonged survival of male SD-rats that bear bladder carcinomas induced either with 44 mg/kg or 28 mg/kg of N-nitroso-N-butyl-N-(4-hydroxybutyl)amine (BBNOH), when daily doses of 350 mg/kg of sodium-2-mercaptoethane sulfonate (mesna) were administered concomitantly. The difference to carcinogen-treated positive controls was highly significant (P = 0.0009 and 0.0013, respectively). Tumor volumes at time of death (P less than 0.005) and frequency of metastases were also reduced in rats that received both compounds in comparison to BBNOH-treated animals.
