Carboplatin plus gemcitabine repeating doublet therapy in recurrent breast cancer

PurposeThe combination of cisplatin plus gemcitabine is active in metastatic breast cancer. Carboplatin plus gemcitabine, widely used in ovarian and non–small-cell lung cancers, has also been used in breast cancer. This trial examined the efficacy and toxicity of split-dose carboplatin plus gemcitabine in advanced breast cancer.Patients and MethodsPatients with measurable disease, recurrent after adjuvant and ≤ 1 previous treatment for systemic disease, received carboplatin area under the curve = 2.0 (Calvert) plus gemcitabine 800 mg/m², both drugs administered days 1 and 8 every 21 days. Of 15 patients accrued, 13 are fully evaluable.ResultsThere were 2 complete (13.3%) and 6 partial (40%) responses, for an overall response rate by intention to treat of 53.3% (95% CI, 28%-82%). The median time to progression was 4.5 months (95% CI, 2.03-6.97 months), and median overall survival was 28.8 months (95% CI, 9.4-48.2 months). There were 2 patients with grade 3 (13.3%) anemia, 7 patients with grade 3 (46.6%) and 4 patients (26.6%) with grade 4 neutropenia, 4 patients with grade 3 (26.6%) and 3 patients (20%) with grade 4 thrombocytopenia.ConclusionThe repeating doublet of split-dose carboplatin plus gemcitabine reveals activity comparable to that of cisplatin plus gemcitabine, is well tolerated, and warrants evaluation in patients with recurrent breast cancer.     

Multicentre phase II study of oxaliplatin as a single-agent in cisplatin/carboplatin +/- taxane-pretreated ovarian cancer patients.

BACKGROUND: This multicentre phase II open-label study evaluated safety and antitumour activity of oxaliplatin in cisplatin or carboplatin (cis/carboplatin) +/- taxane-pretreated advanced ovarian cancer (AOC) patients. PATIENTS AND METHODS: Forty-eight patients received oxaliplatin 130 mg/M2 intravenously every 3 weeks, 94% having a performance status (PS) 0-1. All were pretreated with cis/carboplatin and 21 (44%) with paclitaxel. The median number of involved organs was two, 18 (38%) had liver metastasis, 23 (48%) were platinum-resistant and 14 (29%) were taxane-resistant. Forty-two patients were evaluable for a response, 18 (43%) were platinum-resistant and 11 (26%) were taxane-resistant. RESULTS: A total of 253 cycles was administered (median: 5.5/patient). Median cumulative oxaliplatin dose was 666 mg/m2. National Cancer Institute-Common Toxicity Criteria toxicity analysis showed that seven patients (15%) had grade 3/4 thrombocytopenia, two patients (4%) had grade 3 neutropenia, and one patient had grade 3 anaemia. Eleven patients (23%) experienced grade 3 neurosensory toxicity. Of the 29 patients with peripheral neuropathy at the end of treatment, 55% had recovered or improved 1 month later. Eleven objective responses (two complete) were obtained in the 42 evaluable patients [ORR 26%, 95% confidence interval (CI) 14% to 42%], with 10/24 (42%, 95% CI 22% to 63%) in platinum-sensitive, and 1 of 18 (5.6%, 95% CI 0% to 27%) in platinum-resistant patients. Median response duration was 9.2 months (95% CI 6.6% to 11.8%), and median progression-free and overall survival in all treated patients were 4.3 months (95% CI 3.0% to 5.7%) and 15.0 months (95% CI 11.1% to 18.8%), respectively. CONCLUSION: Oxaliplatin has a good safety profile and is active in cis/carboplatin +/- paclitaxel-pretreated AOC patients.     

Treatment of advanced seminoma with cyclophosphamide, vincristine and carboplatin on an outpatient basis.

This study describes the efficacy and toxicity of a combination regimen consisting of cyclophosphamide, vincristine (oncovin) and carboplatin (COC) for advanced seminoma on an outpatient basis. Twenty-seven patients (mean age 43 years, range 28-63 years) were classified as stage IIC (n = 5), stage IID (n = 12), stage III (n = 9) or stage IV (n = 1). Six had been treated with prior radiotherapy; elevated beta-HCG and elevated LDH serum levels were observed in 15 and 25 patients respectively. Patients were treated with four cycles of 750 mg m-2 cyclophosphamide intravenously (i.v.), 1.4 mg m-2 vincristine i.v. (maximum 2 mg) and carboplatin adjusted to creatinine clearance. Cycles were given at 3 week intervals. The median dose of carboplatin administered was 400 mg m-2 (range 300-450 mg m-2). Six patients [22%; 95% confidence interval (CI), 6-38%] achieved a complete response (CR), 19 (70%; 95% CI, 51-88%) a partial response and two (8%; 95% CI, 0 18%) showed only a response in tumour markers but not a reduction of retroperitoneal mass (NR). Post-chemotherapeutic masses were not removed surgically or irradiated. After a median follow-up of 26 months (range 5-69 months), two patients have died, one from cardiac arrest 2 years after achieving CR, the other with relapsed seminoma 5 months after therapy. None of the other patients relapsed. Main toxicity was haematological, with 22 patients (81%) experiencing thrombocytopenia WHO grade III/IV and 27 (100%) leucocytopenia WHO grade III/IV, requiring dose reduction in five patients. Seven patients experienced granulocytopenic fever. Non-haematological toxicity was rare. Peripheral neuropathy grade I was observed in four patients and grade III in one. Haemorrhagic cystitis occurred once. In conclusion, despite considerable haematological toxicity, COC is feasible on an outpatient basis, even after prior radiotherapy, and is an effective regimen for advanced seminoma with only 1/27 treatment failures after a median follow-up of 26 months.     

Phase II trial of carboplatin in the management of malignant mesothelioma

Thirty-one patients with advanced malignant mesothelioma, previously untreated or having received only one prior cytotoxic regimen, were treated in a prospective, single-arm phase II trial with carboplatin (NSC 241240) at a dose of 150 mg/m2 per day intravenously (IV) for 3 days (450 mg/m2/course). One complete remission and four partial remissions were achieved, yielding an overall objective response rate of 16% (95% confidence interval [CI], 5.4% to 34%). The median duration of remission was 8 months (range, 5 to 17). Nonhematological toxicity was mild (only 12% with World Health Organization [WHO] grade 3 vomiting); 16% suffered WHO grade 3 to 4 hematological toxicity, but there were no life-threatening episodes and no treatment-related deaths. Carboplatin has modest activity against malignant mesothelioma and, because of its low toxicity, has a role in the management of this disease.     

Carboplatin and vinorelbine in untreated locally advanced and metastatic non-small cell lung cancer

The aim of this study was to assess the activity and toxicity of carboplatin/vinorelbine combination chemotherapy in unresectable locally advanced and metastatic non-small cell lung cancer. Between April 1997 and June 1999 30 patients (22 M, eight F, median age 62) received treatment with carboplatin AUC 6 on day 1, and vinorelbine 25mg/m(2) on days 1, 8 and 15. Treatment was given every 28 days for six cycles unless progressive disease occurred. Twenty-three patients (77%) had stage IV disease, and seven (23%) stage IIIB. Ninety-three percent were WHO performance status 0-1. Twenty-three patients were fully assessable. Nine patients achieved partial responses (9/23, 39%) for an overall objective response rate of 9/30 (30%; 95% CI 15-49%). The median duration of response was 2.75 months (range 1-13 months). The median progression-free survival was 2 months and the median survival 5.25 months. The actuarial 1-year survival was 20%. The median number of cycles completed was two (range 1-6). Day 15 vinorelbine was administered in only 18% of cycles. The main toxicity was myelosuppression. WHO grade III/IV neutropenia was experienced in 50% of patients, however, there were only three episodes of febrile neutropenia. Eight patients required blood transfusion and one developed grade III thrombocytopenia. Treatment was ceased in one patient because of grade IV autonomic neuropathy. No patient had significant nausea and vomiting. There were no treatment-related deaths. These results indicate that carboplatin/vinorelbine is well tolerated and has similar activity to cisplatin/vinorelbine in patients with unresectable non-small cell lung cancer, however, the median survival was considerably shorter.     

A phase II study of vinflunine in bladder cancer patients progressing after first-line platinum-containing regimen

A multicentre phase II trial to determine the efficacy of vinflunine as second-line therapy in patients with advanced transitional cell carcinoma (TCC) of the bladder; secondary objectives were to assess duration of response, progression-free survival (PFS) and overall survival (OS), and to evaluate the toxicity associated with this treatment. Patients had tumours that failed or progressed after first-line platinum-containing regimens for advanced or metastatic disease, or had progressive disease after platinum-containing chemotherapy given with adjuvant or neoadjuvant intent. Response and adverse events were assessed according to WHO criteria and NCI-CTC (version 2), respectively. Out of 51 patients treated with 320 mg m(-2) of vinflunine, nine patients responded to the therapy yielding an overall response rate of 18% (95% CI: 8.4-30.9%), and 67% (95%CI: 52.1-79.3%) achieved disease control (PR+SD). Of note, responses were seen in patients with relatively poor prognostic factors such as a short (<12 months) interval from prior platinum therapy (19%, including an 11% response rate in those progressing <3 months after platinum treatment), prior treatment for metastatic disease (24%), prior treatment with vinca alkaloids (14%) and visceral involvement (20%). The median duration of response was 9.1 months (95% CI: 4.2-15.0) and the median PFS was 3.0 months (95% CI: 2.4-3.8). The median OS was 6.6 months (95% CI: 4.8-7.6). The main haematological toxicity was grade 3-4 neutropenia, observed in 67% of patients (42% of cycles). Febrile neutropenia was observed in five patients (10%) and among them two were fatal. Constipation was frequently observed (but was manageable and noncumulative) and was grade 3-4 in only 8% of patients. The incidence of grade 3 nausea and vomiting was very low (4 and 6% of patients, respectively). Neither grade 3-4 sensory neuropathy nor severe venous irritation was observed. Moreover, and of importance in this particular study population, no grade 3-4 renal function impairment was observed. Vinflunine is an active agent for the treatment of platinum-pretreated bladder cancer, and these results warrant further investigation in phase III trials, either as monotherapy or in combination with other agents as treatment of advanced/metastatic TCC of the bladder.     

Intensive induction chemotherapy with C-BOP/BEP for intermediate- and poor-risk metastatic germ cell tumours (EORTC trial 30948)

New chemotherapy regimens are continuously explored in patients with high-risk malignant germ cell tumours (MGCTs). This multicentre phase II trial assessed the efficacy and toxicity of C-BOP/BEP chemotherapy in intermediate and poor prognosis MGCT (IGCCCG criteria). C-BOP/BEP treatment consisted of cycles of cisplatin, vincristine, bleomycin and carboplatin, followed by one cycle of vincristine and bleomycin and three cycles of BEP (bleomycon, etoposide, cisplatin). The trial was designed to demonstrate a 1-year progression-free survival rate of 80%, that is, to exclude a 1-year rate of 70% or less, with a one-sided significance level of 5%. Secondary end points included toxicity, overall survival and the postchemotherapy complete response rate. In total, 16 European hospitals entered 66 eligible patients (intermediate prognosis group: 37; poor prognosis group: 29). A total of 45 patients (68.2%, 95% confidence interval (95% CI): 56.9-79.4%) achieved a complete response (intermediate prognosis: 30; poor prognosis: 15). After a median observation time of 40.4 months (range: 13.7-66.3), the 1-year progression-free survival rate was 81.8% 95% CI: 72.5-91.1%). The 2-year overall survival was 84.5% (95% CI: 75.6-93.3%). In all, 51 patients experienced at least one episode of WHO grade 3/4 leucopenia, and at least one event of grade 3/4 thrombocytopenia occurred in 30 patients. There was no toxic death. With an 82% 1-year progression-free survival and a lower limit of the 95% CI above 70%, the efficacy of C-BOP/BEP is comparable to that of published alternative chemotherapy schedules in high-risk MGCT patients. The treatment's toxicity is manageable in a multicentre setting. In poor prognosis patients, C-BOP/BEP should be compared to standard chemotherapy of four cycles of BEP.     

Concurrent weekly carboplatin and radiotherapy for nasopharyngeal carcinoma: report of a joint phase II study.

We report a phase I/II study of weekly concurrent carboplatin and radiotherapy in patients with nasopharyngeal carcinoma (M0 stage). Of 47 patients registered, 45 completed the treatment course. Twenty-six (55%) (95% CI, 41-69%) patients experienced > or =grade 3 acute toxicity (RTOG). Five (11%) (95% CI, 2-20%) patients experienced > or =grade 3 chronic toxicity. This regimen appears to have acceptable toxicity compared to the experimental arm of Phase III Intergroup Study 0099, but progression-free and overall survival are probably inferior. At present, there is no data to suggest that carboplatin can replace cisplatin for concurrent chemoradiation for NPC.

Topotecan and carboplatin in patients with platinum-sensitive recurrent ovarian cancer. Results of a multicenter NOGGO: phase I/II study

OBJECTIVE: Second-line treatment with paclitaxel and carboplatin enhances survival of women with platinum-sensitive recurrent ovarian cancer (ROC). However, because of its cumulative neurotoxicity, there is a strong demand for platinum-combinations with better therapeutic index. Because of its pharmacological properties, topotecan is a good adjunct to carboplatin in this setting, but its safety and efficacy remains to be defined. METHODS: Patients with platinum-sensitive ROC were eligible in this multicenter phase I/II study, stratified according to treatment-free interval (TFI). Dose level 0 consisted of topotecan 1 mg/m(2)/d1-3/q21d plus carboplatin AUC5/d3/q21d. DLT was defined as grade > or =3 neutropenia or thrombocytopenia or grade > or =3 non-hematological toxicity excluding alopecia, nausea and vomiting, accompanied by a treatment delay >1 week. RESULTS: From June 2004 to August 2005, 26 patients were enrolled, receiving a total of 145 cycles of chemotherapy. MTD was reached at topotecan 0.75 mg/m(2) and carboplatin AUC5. We observed a single grade 4 leucopenia. There were 3 (12%), 15 (58%) and 8 (31%) events of grade 3/4 hematological anaemia, leucopenia, and thrombocytopenia. Response rate was 67% (95% CI 43-85), median progression-free survival 9.5 months (95% CI 7.3-12.0), median overall survival 19.4 months (95% CI 12.3-26.9). None of the toxicity or efficacy endpoints were associated with TFI. CONCLUSION: Topotecan and carboplatin is a well tolerated novel doublet option for women with platinum sensitive ROC. We encourage further studies on this approach, but to limit the doses of topotecan to 0.75 mg/m(2)/d1-3 and carboplatin AUC 5/d3.

Phase II study of paclitaxel and carboplatin in advanced gastric cancer previously treated with 5-fluorouracil and platinum

BACKGROUND: The combination of paclitaxel and carboplatin has been used to treat patients with many types of tumor, including gastric cancer. We evaluated the efficacy and safety of this combination in advanced gastric cancer patients previously treated with 5-fluorouracil and platinum. METHODS: Patients who had pathologically been proven to have measurable lesions were treated with paclitaxel (200 mg/m(2) for 3 h) and carboplatin [area under the concentration-time curve (AUC = 6)] on day 1 and in 21 day cycles. RESULTS: A partial response was achieved in 10 of 45 patients [22%, 95% confidence interval (CI), 10-34]. Of the 32 patients previously treated with cisplatin, four (13%) achieved partial response, whereas, of the 13 patients previously treated with heptaplatin, six (46%) achieved partial response. In all patients, the median time to progression was 14 weeks (95% CI, 10-18), and the median overall survival was 32 weeks (95% CI, 26-38). The most common grade 3/4 adverse events were neutropenia (40% of patients) and neuropathy (2.2%). Two patients developed neutropenic fever. However, there were no treatment-related deaths. CONCLUSIONS: Combination chemotherapy with paclitaxel and carboplatin is feasible in patients with advanced gastric cancer who were previously treated with 5-fluorouracil and platinum.     

A comparison of the toxicity and efficacy of cisplatin and carboplatin in advanced ovarian cancer. The Swons Gynaecological Cancer Group

Eighty-eight patients with stage IIB-III epithelial ovarian cancer were randomised to receive first line single agent cisplatin (100 mg/m2) monthly or carboplatin (400 mg/m2) monthly for up to 5 cycles. Crossover to the opposite analogue occurred with progression or lack of response. All patients were premedicated with i.v. methylprednisolone (500 mg at 0 hours and 250 mg at 3 hours) and the first 20 patients in both groups received lorazepam and prochloperazine for nausea and vomiting. The median number of vomiting episodes per cycle with cisplatin was 16 and with carboplatin 2 (p less than 0.001). In the cisplatin arm 27/40 (67.5%) developed mild renal toxicity, 9/40 (22.5%) WHO grade I neurotoxicity and 18/40 (45%) evidence of ototoxicity at audiometry. To date we have seen no neuro- or ototoxicity with carboplatin and 1/40 (2.5%) have developed WHO grade I renal toxicity. Myelosuppression and anaemia was more common with carboplatin but only 1 episode of grade IV thrombocytopenia has been seen with first line carboplatin. The clinical response rate (CR+PR) for cisplatin was 19/40 and for carboplatin 27/40. Actuarial survival for cisplatin group at 24 months was 50% and for carboplatin group 58% with no significant difference. Carboplatin appears less toxic than cisplatin producing to date similar survival and response as a single agent.     

Phase II study of cisplatin plus 24-hour infusion of ifosfamide in advanced malignant melanoma

A phase II study with cisplatin plus 24-hour infusion of ifosfamide (with mesna uroprotection) was performed in patients with metastatic malignant melanoma. The overall response rate was 40% (7% complete and 33% partial remission). The response rate in patients with a WHO performance score of 0 was 64%. Survival for patients in partial remission ranged from 1-12 months (median 7), which is disappointing in view of the toxicity. Side effects were substantial, with severe leucopenia in 82% and thrombocytopenia in 71%. Renal toxicity was observed in 31% and was severe in 6%. There was 1 toxic death. Although the response rate is high, toxicity precludes the standard use of this regimen until the effect of rescue agents for myelo- and renal toxicity is proven.     

A phase II study of a daily x4 schedule of vinorelbine plus cisplatin for advanced non-small cell lung cancer

BACKGROUND: Because dose intensity may be important as a determinant response to vinorelbine, we explored the possibility of increasing the dose intensity of vinorelbine on a daily x4 schedule. METHODS: Between February 1998 and March 1999, 31 patients with previously untreated advanced non-small cell lung cancer were enrolled. Vinorelbine 15 mg/m2 and cisplatin 20 mg/ m2 were administered intravenously daily for 4 days and repeated every 21 days. RESULTS: A total 96 cycles were administered (median 3, range 1-6); 42% of vinorelbine and 39% of cisplatin injections were dose-reduced or delayed owing to toxicity. The actual dose intensity (DI) of vinorelbine was 17.7 mg/m2/week and that of cisplatin was 24 mg/m2/week. These figures represent 88 and 90% of the theoretical DI, respectively. The overall response rate was 40% (12/30, one CR). The main toxicity was myelosuppression: granulocytopenia WHO grade 3 and 4 in 24 patients (77%) and thrombocytopenia grade 3 in two patients (6%). The non-hematological toxicity was mild and tolerable. After a median follow-up of 7.5 months (range 3-21 months), the median progression-free survival and overall survival times were 5 months (95% CI, 3.8-6.2) and 8 months (95% CI, 4.5-11.5), respectively. CONCLUSIONS: This regimen has a comparable therapeutic activity in patients with advanced lung cancers. However, despite supportive care there were excessive hematological toxicities. In view of increased toxicity and similar efficacy, this regimen is not indicated outside a clinical trial.     

A phase II study of gemcitabine and cisplatin in chemotherapy-naive, unresectable gall bladder cancer

The primary objective of this study was to determine the response rates of the gemcitabine and cisplatin combination in unresectable gall bladder cancer patients. The secondary objectives were to evaluate the toxicity, time to progressive disease, and overall survival. Chemona?ve patients with histologically proven, unresectable bidimensionally measurable gall bladder cancer were enrolled into this study. All patients were required to have a Zubrod's performance status 相似文献   

Phase II study of continuous infusional 5-fluorouracil with epirubicin and carboplatin (instead of cisplatin) in patients with metastatic/locally advanced breast cancer (infusional ECarboF): a very active and well-tolerated outpatient regimen.

Infusional 5-fluorouracil (F) with cisplatin (C) and epirubicin (E), so-called infusional ECF, is a highly active new schedule against locally advanced or metastatic breast cancer. Cisplatin, however, is a major contributor to toxicity and usually requires inpatient treatment. In an attempt to overcome this, we have investigated the effect of substituting carboplatin for cisplatin in our original infusional ECF regimen. Fifty-two patients with metastatic (n = 36) or locally advanced/inflammatory (n = 16) breast cancer were treated with 5-fluorouracil 200 mg m-2 day-1 via a Hickman line using an ambulatory pump for for 6 months, with epirubicin 50 mg m-2 intravenously (i.v.) and carboplatin AUC5 i.v. every 4 weeks, for six courses (infusional ECarboF). The overall response rate (complete plus partial) was 81% (95% CI 67%-90%), with a complete response rate of 17% (95% CI 6-33%) in patients with metastatic disease and 56% (95% CI 30-80%) in patients with locally advanced disease. Median response duration and survival for metastatic disease was 8 and 14 months respectively, and two patients with locally advanced disease have relapsed. These results are very similar to those previously achieved with infusional ECF. Severe grade 3/4 toxicity was low. Infusional ECarboF is a highly active, well-tolerated, outpatient regimen effective against advanced/metastatic breast cancer and now warrants evaluation against conventional chemotherapy in high-risk early breast cancer.     

Lack of impact of platinum dose intensity on the outcome of ovarian cancer patients. 10-year results of a prospective randomised phase III study comparing carboplatin-cisplatin with cyclophosphamide-cisplatin

This prospective multicentre phase III trial was conducted to assess whether increased platinum dose intensity (DI) by combining carboplatin with cisplatin has an impact on overall survival (OS) and progression-free interval (PFI) compared with the standard combination of cyclophosphamide and cisplatin in patients with epithelial ovarian cancer. A total of 253 patients with epithelial ovarian cancer of stages International Federation of Gynecology and Obstetrics (FIGO) IC-IV were randomised to receive either cyclophosphamide (600 mg/m(2), intravenously (i.v.), day 1) and cisplatin (100 mg/m(2), i.v., day 2) (n=125) as the standard regimen or carboplatin (300 mg/m(2), i.v., day 1) and cisplatin (100 mg/m(2), i.v., day 2) (n=128), every 28 days for six courses. The median follow-up was 6.0 years. 124 patients randomised to the platinum dose-intensified arm and 123 patients randomised to the standard arm met all of the eligibility criteria. Patient characteristics were well balanced between the two treatment groups. All eligible patients randomised were included in the analysis of OS and PFI. The median OS of the standard and platinum dose-intensified arms were 41.2 (95% Confidence Interval (CI): 29.2-50.7) and 43.0 months (95% CI: 34.3-63.2), respectively (P=Non-significant (N.S.). The median PFI in the standard arm was 29.7 (95% CI: 17.4-41.7) versus 23.1 months (95% CI: 17.8-35.4) in the platinum dose-intensified arm, respectively (P=N.S.). Toxicity, comprising leucopenia, granulocytopenia, thrombocytopenia, anaemia, emesis and nausea, was statistically significantly higher in the platinum dose-intensified arm than in the standard arm. Unexpectedly, no statistically significant differences were found between the 2 arms' overall neuro- and ototoxicity. When converting carboplatin-platinum into cisplatin-platinum on the basis of an equivalence ratio of 4:1, patients in the platinum dose-intensified arm received a total platinum dose 1.58 times the platinum dose of the standard arm. With 35.0 mg/m(2)/week being administered, the total platinum DI of the dose-intensified arm was statistically significantly (P<0.0001) higher than that of the standard regimen (with 22.0 mg/m(2) being administered). Calculating the average administered relative dose intensities of the regimens yielded almost identical results with 0.56 and 0.58 for the standard and experimental arms, respectively. Thus, by conventional means, a 1.6-fold increase in the platinum DI could be reached by combining carboplatin and cisplatin without unacceptable morbidity. Nevertheless, this did not translate into any therapeutic benefit for the patient, even in the optimally debulked group of patients for whom dose-intensification would have been expected to be of benefit.     

Phase II study of mitomycin-C and cisplatin in disseminated, squamous cell carcinoma of the uterine cervix. A European Organization for Research and Treatment of Cancer (EORTC) Gynecological Cancer Group study

The aim of this study was to investigate the tumour response rate and toxicity of a combination chemotherapy consisting of mitomycin-C and cisplatin in patients with disseminated squamous-cell carcinoma of the uterine cervix. Chemotherapy consisted of mitomycin, 6 mg/m(2) intravenously (i.v.), and cisplatin, 50 mg/m(2) given i.v., both administered on day 1 of each cycle. The regimen was repeated at 4-weekly intervals. Mitomycin-C/cisplatin were used to treat 33 evaluable patients aged 29-67 years (median: 50 years). All patients except 1 had previously been treated with either surgery, radiation or both. At the initiation of chemotherapy, 8 patients had loco-regional and disseminated disease and 25 women had only distant metastases. The overall response rate was 42% (95% confidence interval (CI): 26-61%). Five complete and nine partial responses were observed with a median duration of response of 7.9 months (95% CI: 3.7-23.5 months). 9 patients had stable disease and 10 developed progressive disease during mitomycin-C/cisplatin-treatment. World Health Organization (WHO) grade III/IV side-effects were documented in 15 women, of whom 10 had gastro-intestinal toxicity, 3 had haematological toxicity, 1 had alopecia and 1 developed an allergic reaction to cisplatin. There were neither drug-related deaths nor severe or irreversible renal or hepatic dysfunction or peripheral neuropathy. The median progression-free survival was 5.0 months (95% CI: 3.6-6.2 months) for all patients and 10.5 months (95% CI: 6.2-15.2 months) for the responders. The median overall survival was 11.2 months (95% CI: 6.5-18.4 months).The mitomycin-C/cisplatin combination showed antitumour activity in the treatment of advanced or recurrent squamous-cell carcinoma of the uterine cervix. The regimen was well tolerated and could be administered on an outpatient basis.     

ESHAP as salvage therapy for refractory non-Hodgkin's lymphoma: Taiwan experience

BACKGROUND: The ESHAP regimen, a combination of the chemotherapeutic drugs etoposide, methylprednisolone (solumedrol), high-dose cytarabine (ara-C) and cisplatin, has been shown to be active against refractory non-Hodgkin's lymphoma in therapeutic trials. We were interested in determining whether this regimen would be effective and tolerable for Chinese patients. METHODS: Thirty-two patients with refractory/relapsed non-Hodgkins lymphoma (23 intermediate-grade and nine high-grade) were enrolled in this study. Etoposide was administered at a dose of 40 mg/m2/day as a 1 h intravenous infusion from day 1 to day 4, solumedrol 500 mg/day was given as a 15 min intravenous infusion from day 1 to day 5, ara-C 2 g/m2 was given as a 2 h intravenous infusion on day 5 and cisplatin was given at a dose of 25 mg/m2/day as a continuous infusion from day 1 to day 4. Clinical efficacy and toxicity were assessed on the basis of the WHO criteria. RESULTS: Ten patients (31.3%, 95% Cl 15.2-47.4%) attained complete remission (CR) and seven had partial remission (PR). The overall response rate was 53.1% (95% Cl 35.8-70.4%). In eight of the 10 CR patients, the remission lasted for more than 8 months. The remaining two patients had CR of 5 and 6 months. The median duration of CR was 12.2 months (range 5-22 months). Myelosuppression with subsequent infections was the major toxicity. Severe leukopenia (WBC < 1000/microliter) lasted for an average of 12 days and thrombocytopenia (< 25,000/microliter) 18 days. One patient (3.1%) died of neutropenia-associated sepsis within 4 weeks after treatment. Non-myeloid toxicities included alopecia in 66% (28% grade 2, 22% grade 3), stomatitis in 72% (25% grade 2, 28% grade 3, 13% grade 4), hepatotoxicity in 9% (3% grade 2), renal toxicity in 13% (6% grade 2, 3% grade 3) and infection in 56% (18% grade 2, 25% grade 3, 13% grade 4). The majority of the responders relapsed within 2 years after ESHAP treatment. Median survival for all patients was 8.6 months. CONCLUSIONS: ESHAP is an active and tolerable regimen in Chinese patients with relapsed/refractory lymphoma, but the duration of remission is brief and without significant impact on survival.
