Two-drug therapy in patients with metastatic germ cell tumors.

Eighty-two patients with metastatic germ cell tumors (GCT) treated with two-drug therapy consisting of etoposide and cisplatin were evaluated for late relapse. Good-risk GCT was defined using Memorial Sloan-Kettering Cancer Center (MSKCC) criteria. Etoposide was given at 100 mg/m2 on days 1 to 5 and cisplatin was given at 20 mg/m2 on days 1 to 5; therapy was recycled at 21 days with delays up to 7 days for a leukocyte count of less than 3000/microliters or a platelet count of less than 100,000/microliters. Drug doses were not attenuated for myelosuppression. Seventy-six of 82 evaluable patients achieved a complete response (CR). Seventy-two patients had a CR to chemotherapy alone. Forty-six (56%) patients had excision of residual abnormalities: 11 had teratoma in the resected specimen, 31 had necrotic debris or fibrosis, and 4 had a CR after chemotherapy plus complete excision of residual viable GCT. Six patients had an incomplete response to chemotherapy; one of these patients had unresectable mature teratoma and remains progression-free. The median etoposide dose (+/- standard deviation [SD]) was 500 mg/m2/course (+/- 35 mg/m2) and the median cisplatin dose (+/- SD) was 100 mg/m2/course (+/- 6 mg/m2). Nine patients experienced a relapse at 6 to 17.5 months; two patients with nonseminomatous GCT were salvaged by chemotherapy and one patient with seminoma was salvaged by chemotherapy and radiation therapy. The three patients who were salvaged by additional therapy are disease-free at 59 to 63 months. Seventy-one patients (87%) remain disease-free with a median follow-up time of 63 months (range, 33 to 92 months). No relapses have occurred beyond 17.5 months. Etoposide and cisplatin therapy at these doses and schedule results in durable CR without late relapse.     

Lomustine (chloroethylnitrosourea [CCNU]), ifosfamide, bleomycin, vincristine, and cisplatin (CIBO-P) is an effective regimen for patients with poor prognostic refractory or multiple disease recurrent aggressive non-Hodgkin lymphoma

BACKGROUND: The current study was designed to assess the activity and safety of a novel combination therapy for patients with recurrent or refractory aggressive non-Hodgkin lymphoma (NHL). METHODS: Forty-three consecutive patients with recurrent or refractory aggressive NHL were treated with lomustine (chloroethylnitrosourea [CCNU]; 60 mg/m2 on Day 1), ifosfamide (1.5 g/m(2 on Days 1, 2 and 21, 22), bleomycin (5 mg/m2 on Days 1, 5 and 21, 25), vincristine (1.4 mg/m2 on Days 1, 8 and 21, 28), and cisplatin (25 mg/m2 on Days 3, 4, 5 and 23, 24, 25), every 42 days (CIBO-P regimen). RESULTS: Thirty-nine patients (91%) were evaluable for response. The median patient age was 63 years. Thirty-five percent of the patients had received > or = 2 lines of previous chemotherapy and 40% had elevated lactate dehydrogenase levels at the time of treatment initiation. The overall objective response rate was 77% (95% confidence interval [95% CI], 63-90%), including 19 (49%) complete (CR) and 11 (28%) partial responses. CIBO-P induced responses in primary refractory disease and in patients treated for second or subsequent disease recurrences. A CR with previous therapy was the most important factor associated with a significantly higher CR rate. The median duration of response was 6 months (95% CI, 4.4-7.7 months) and the median survival duration was 10.7 months (95% CI, 5.9-18.1 months). Five patients (11.6%) remained disease free for > or = 24 months. By multivariate analysis, a CR with previous therapy and average dose intensity of CIBO-P drugs were independent prognostic factors for time-to-treatment failure, whereas a CR with previous therapy and serum lactate dehydrogenase were independent predictors for survival. Myelosuppression was the most frequent serious complication of this regimen. However, none of the patients had hemorrhage with thrombocytopenia, and only 2 patients (5%) had febrile neutropenia. CONCLUSIONS: In the current study, CIBO-P was a novel, highly active, and safe combination therapy for patients with refractory disease with a poor prognosis or for patients with multiply recurrent aggressive NHL.     

Mature survival results with preoperative cisplatin,protracted infusion 5-fluorouracil,and 44-Gy radiotherapy for esophageal cancer

PURPOSE: To assess the long-term survival results after cisplatin, protracted infusion 5-fluorouracil, and concurrent radiotherapy (RT) followed by surgical resection of esophageal cancer. METHODS AND MATERIALS: Ninety-two patients with esophageal cancer (65 with adenocarcinoma and 27 with squamous cell carcinoma) were treated in two sequential protocols of preoperative chemoradiotherapy. The patients had tumor confined to the esophagus and regional nodes, including celiac nodes for middle and distal lesions. In trial A (1989-1994), 50 patients were treated with 44 Gy RT (2 Gy/d) along with concurrent 5-fluorouracil 300 mg/m(2)/d given by protracted venous infusion on Days 1-30 and cisplatin 26 mg/m(2) on Days 1-5 and 26-30. In trial B (1995-1997, 42 patients), the chemotherapy dosages during RT were reduced to 5-fluorouracil 225 mg/m(2)/d protracted venous infusion and cisplatin 20 mg/m(2)/d on Days 1-5 and 16-30; three cycles of paclitaxel 135 mg/m(2)and cisplatin 75 mg/m(2) were given postoperatively. Surgery generally occurred 4-6 weeks after completion of the planned preoperative therapy. Transhiatal resection was performed whenever possible. RESULTS:Of the 92 patients, 86 (93%) underwent surgery (1 refused, 2 died preoperatively, and 3 developed evidence of metastatic disease). Of the 92 patients, 80 (87%) had complete resections with negative margins (3 had positive margins and 3 had distant metastases discovered at surgery). The pathologic complete response rate was 33% (30 of 92). The median follow-up was 63.5 months. The median survival and disease-specific survival for all enrolled patients was 35 and 59 months, respectively. The 5-year survival and disease-specific survival rate was 40% and 49%, respectively. Patients with a pathologic complete response had a 67% survival rate at 5 years (median not reached), and the remainder of patients had a 5-year survival rate of 27% (median 21 months; p <0.001). For 21 patients alive after 5 years (60-121 months), 2 died of their disease and all others were disease free. Eight patients with pathologic Stage I tumor at the time of surgery had survival similar to those with a complete response to preoperative therapy. The median survival for patients with pathologic Stage IIA, IIB, III, and IV disease at the time of surgery was 22, 13.5, 18, and 4.9 months, respectively. The pattern of initial failure was local/regional alone in 6% (5 of 90), local/regional plus distant in 3% (3 of 90), and distant alone in 47% (42 of 90). No differences were noted in survival or response rate between those with adenocarcinoma or squamous cell carcinoma. CONCLUSION: The promising 5-year survival results and low rate of late cancer-related deaths suggest that these regimens of intensive neoadjuvant therapy may improve the overall cure rate. The pathologic stage after neoadjuvant therapy is an important predictor of survival and may be useful in selecting patients for novel adjuvant therapies. Isolated local failure is uncommon, indicating that efforts to improve the therapeutic outcome should focus on optimizing systemic therapy rather than intensifying the RT. Additional randomized data are needed to assess the benefits of this therapeutic approach fully.     

Treatment of previously treated metastatic breast cancer by mitoxantrone and 48-hour continuous infusion of high-dose 5-FU and leucovorin (MFL): low palliative benefit and high treatment-related toxicity

For previously treated advanced breast cancer, there is no standard second-line therapy. Combination chemotherapy with mitoxantrone, high-dose 5-fluorouracil (5-FU) and leucovorin (MFL regimen) had been reported as an effective and well tolerated regimen. From October 1993 to November 1995, we treated 13 patients with previously chemotherapy-treated metastatic breast cancer by mitoxantrone, 12 mg/m2, on day 1 and continuous infusion of 5-FU, 3000 mg/m2, together with leucovorin, 300 mg/m2, for 48 h from day 1 to 2. Each course of chemotherapy was given every 4 weeks. Most of these patients had more than two metastatic sites, with lung metastasis predominant. Seven patients had been treated with anthracycline. Seven patients had previously received radiotherapy and seven had received hormone therapy. Median number of courses of MFL regimen given was six and the median cumulative dose of mitoxantrone was 68.35 mg/m2. One patient had complete response, seven had stable disease, none had partial response and five had progressive disease. The overall objective response rate was 7.6%. The median follow-up period was 14 months. Median survival was 16 months. Median progression-free survival was 5 months. A complete responder had relapse-free survival up to 17 months. Major toxicities were cardiotoxicity and leukopenia. Eight patients were dead in the last follow-up; two of them died of treatment-related toxicity. The MFL regimen achieves little palliative benefit and induces severe toxicity at a fairly high rate. Administration of this regimen to breast cancer patients who have been treated by chemotherapy and those with impaired heart function requires careful attention.      

Treatment of advanced gastric cancer with DDP (cisplatin), adriamycin, and 5-fluorouracil (DAF)

Sixteen evaluable patients with advanced gastric cancer who had no prior therapy were treated intravenously with cisplatin (DDP) 20 mg/m2/day on days 1-5 and with Adriamycin 40 mg/m2 and 5-fluorouracil 600 mg/m2 on day 1 (DAF) every 3 weeks. There were five objective partial responses, giving a response rate of 31%. Five patients had minor responses, and 5 others achieved disease stabilization. The median duration of response for responders was 10 months, and the median time to tumor progression in nonresponders was 6 months. The overall median survival was 12 months (responders 14 months, nonresponders 9 months; NS). Most patients had a subjective improvement, including disappearance of abdominal pain (7/9) and gastrointestinal bleeding (5/7). The drug toxicity was moderate to severe. The primary nonhematologic toxicities were nausea and vomiting (in all patients), severe weakness (44%), and parasthesias (31%). Eight patients (50%) experienced significant bone marrow suppression. The DAF combination appears to have some activity in patients with advanced gastric cancer. However, further efforts in new drug development and other combinations are needed to improve the results of chemotherapy in stomach cancer.     

New multiple-agent chemotherapy (B-DOPA) for advanced Hodgkin's disease.

B-DOPA (Bleomycin (B), D-imidazole carboxamide (D), Oncovin (O), Prednisone (P), Adriamycin (A) is a program developed for the treatment of Hodgkin's disease resistant to MOPP therapy. Twenty unselected patients were treated by the following dose schedule: B, 4 mg/m2 days 2 and 5; D, 150 mg/m2 days 1 to 5; O (vincristine), 1.5 mg/m2 days 1 and 5; P, 40 mg/m2 days 1 to 6; A, 60 mg/m2 day 1. Each course, was repeated at 3 to 4 week intervals to maximum adriamycin dose of 450 mg/m2. All patients had received prior MOPP therapy and six had received prior radiotherapy. Fifteen of the 20 patients entered into the study were evaluable for response. There were nine (60%) complete responders and three (20%) partial responders. The median duration of complete remission was 14+ months with six of nine patients remaining in remission to a maximum of 21 months. The median survival of the nonresponders was 3 months. B-DOPA is an effective combination chemotherapy regimen for advanced Hodgkin's disease in patients who have previously received MOPP treatment, including patients who are refractory to MOPP therapy. The B-DOPA program or modifications thereof, may be integrated into primary treatment programs for advanced Hodgkin's disease.     

Phase II trial of an ambulatory treatment with 5-fluorouracil administered by continuous perfusion combined with vindesine and cyclophosphamide

Thirty-four patients with histologically proven metastatic breast cancer, were included in this phase II trial. They were given a five day course of continuous infusion of 5 fluoro-uracile at the daily dose of 500 mg/m2 associated with vindesine 2 mg/m2 on day 2 and 5, cyclophosphamide 300 mg/m2 on day 2 and 5. The treatment was repeated every 15 days after haematological and biological assay. Twenty-six patients were objectively resistant to previous cytotoxic chemotherapy including adriamycin and 6 patients had recently received adjuvant therapy. A major objective response was observed in 17 cases (50%) (4 complete responses, 13 responses greater than 50%) and a response less than 50% in 7 cases. The median duration of response is over 8 months. After 8 months of median follow-up, the median of survival is not defined.     

Treatment of locally advanced breast cancer using primary induction chemotherapy with hormonal synchronization followed by radiation therapy with or without debulking surgery

Fifty-one patients with stage IIIA or IIIB locally advanced breast cancer received primary induction chemotherapy (hormonal synchronization, 46 patients) to a maximum objective clinical response before proceeding to local therapy. Patients achieving a pathological complete response (CR) received radiation therapy, while patients with residual disease, partial response (PR), or stable disease (NC) received debulking surgery prior to radiation therapy; in all patients, 6 additional months of chemotherapy were administered. Chemotherapy consisted of cyclophosphamide (500 mg/m2 iv) and doxorubicin (30 mg/m2 iv) on day 1; tamoxifen (40 mg/m2 orally) on days 2-6; Premarin (0.625 mg/m2 orally) every 12 hours for three doses, beginning on day 7; and methotrexate (300 mg/m2 iv) followed in 1 hour by 5-fluorouracil (500 mg/m2 iv) on day 8 and leucovorin rescue (10 mg/m2 orally) every 6 hours for six doses, beginning 24 hours after methotrexate. Fifty patients are evaluable with respect to response, time to disease progression, and survival. The rate of objective response to chemotherapy was 90%; 52% of the patients had CR, 38% had PR, and 10% had NC. The median numbers of chemotherapy cycles to achieve CR, PR, and NC were five, four, and four, respectively. Twenty-four patients with CR to chemotherapy were pathologically assessed, 22 by multiple biopsies and 2 by mastectomy. Seventy-one percent of the patients were proven to have pathological CR. All patients completing combined therapy thus far are disease free. Nine of 29 patients with stage IIIB disease have relapsed; 7 of 23 with inflammatory histology have relapsed; and 2 of 20 with stage IIIA disease have relapsed.(ABSTRACT TRUNCATED AT 250 WORDS)     

Multicentre phase II study of bifractionated CPT-11 with bimonthly leucovorin and 5-fluorouracil in patients with metastatic colorectal cancer pretreated with FOLFOX

This multicentre phase II study was designed to evaluate the antitumour activity and toxicity of bifractionated camptothecin (CPT-11) and 5-fluorouracil/ leucovorin (5-FU/LV) in the treatment of patients with metastatic colorectal cancer (MCC) who had been pretreated with 5-FU/LV-oxaliplatin (FOLFOX regimen). In all, 35 patients were enrolled in a two-stage trial. Treatment consisted of two daily doses of CPT-11, 90 mg m2 administered over 90 min, followed by LV, 200 mg m2 administered over 2 h plus 5-FU 400 mg m2 as a bolus and 600 mg m2 as a 22-h continuous infusion administered with disposable pumps as outpatient therapy. Toxicity was closely monitored. Response was evaluated by computed tomography scans every 8 weeks. All 35 patients were assessable for toxicity and response to treatment. Seven patients had a partial response, giving an overall response rate of 20%; 11 patients had stable disease (31.4%) and 17 progressed (48.5%). The median progression-free survival was 7.1 months and median survival was 14 months. A total of 10 patients (30%) experienced grade 3-4 toxicity, including nausea (15%), diarrhoea (12%) and neutropenia (15%), while seven patients (21%) had grade 2 alopecia. The bifractionated bimonthly schedule of CPT-11 plus 5-FU/LV showed substantial antitumour activity and was well tolerated in this group of patients with a poor prognosis, pretreated with the FOLFOX regimen.     

Triplet combination with irinotecan plus oxaliplatin plus continuous-infusion fluorouracil and leucovorin as first-line treatment in metastatic colorectal cancer: a multicenter phase II trial.

PURPOSE: To evaluate the efficacy and tolerance of irinotecan (CPT-11) in combination with oxaliplatin (L-OHP) plus fluorouracil (5-FU)/leucovorin (LV) (de Gramont regimen) as first-line treatment of metastatic colorectal cancer (MCC). PATIENTS AND METHODS: Thirty-one patients with MCC who had not received prior therapy for metastatic disease were enrolled. Their median age was 60 years; performance status (World Health Organization) was 0 in 12, 1 in 14, and 2 in five patients; 19 patients (61%) had prior surgery, and 14 (45%) had adjuvant chemotherapy. CPT-11 was administered on day 1 at 150 mg/m(2) as a 90-minute intravenous (IV) infusion; L-OHP was administered on day 2 at 65 mg/m(2) as a 2-hour IV infusion; and on days 2 and 3, LV 200 mg/m(2) preceded 5-FU administration of 400 mg/m(2)/d initial IV bolus dose followed by 600 mg/m(2)/d 22-hour IV continuous infusion. The regimen was repeated every 2 weeks. RESULTS: All patients were assessable for toxicity and 30 for response to treatment. Complete response was achieved in two patients (6.5%) and partial response in 16 (51.6%) (overall response rate, 58.1%; 95% confidence interval, 40.7% to 75.4%); eight patients (25.8%) had stable disease, and five (16.1%) had disease progression. The median duration of response was 9 months, and the median time to disease progression was 13 months. Neutropenia grade 3 to 4 occurred in 14 patients (45%) and febrile neutropenia in two (6%). Diarrhea grade 3 to 4 was observed in 10 patients (32%), neurotoxicity grade 3 to 4 in three (9%), and asthenia grade 3 in two (10%). No treatment-related death has occurred. CONCLUSION: The triplet combination of 5-FU/LV + CPT-11 + L-OHP is a highly active regimen with manageable toxicity as front-line treatment in MCC.     

A phase I trial of temozolomide and lomustine in newly diagnosed high-grade gliomas of childhood

A phase I trial was conducted to determine the maximum tolerated dose (MTD) of temozolomide given in combination with lomustine in newly diagnosed pediatric patients with high-grade gliomas. Response was assessed following two courses of therapy at the MTD. Temozolomide was administered to cohorts of patients at doses of 100, 125, 160, or 200 mg/m(2) on days 1-5, along with 90 mg/m(2) lomustine on day 1. Two courses of lomustine/temozolomide were given prior to radiation therapy (RT) and up to six courses were administered afterward. Thirty-two patients were enrolled. Dose-limiting myelosuppression was seen in two of three patients enrolled at the 200 mg/m(2) dose level. One of 14 patients in the expanded MTD cohort (160 mg/m(2)) experienced dose-limiting thrombocytopenia. After two courses at the MTD, one patient with a 5-mm enhancing nodule postoperatively had a complete response, one patient with a large residual temporal lobe glioblastoma had a partial response, and eight patients had stable disease. Several patients developed transient radiographic worsening after completing RT. Median 1- and 2-year overall survivals at the MTD were 60% +/- 13% and 40% +/- 13% with a median of 17.6 months. Thirteen of 20 patients (65%) who underwent MRI scans within 6 months prior to death developed metastatic disease. In conclusion, when administered with 90 mg/m(2) lomustine on day 1, the MTD of temozolomide is 160 mg/m(2)/day x 5. Radiographic changes following RT make determination of early tumor progression difficult. Metastatic disease is common prior to death.     

Effectiveness and toxicity of "BELD" polychemotherapy in advanced malignant melanoma

From January 1985 to December 1987, 17 patients with advanced malignant melanoma were treated with the polychemotherapy regimen BELD (bleomycin, 15 mg subcutaneously on day 1 and 4, vindesine 3 mg/m2 intravenously on day 1 and 5, CCNU 80 mg/m2 orally on day 1 and DTIC 200 mg/m2 intravenously on day 1 through 5) proposed as effective (CR + PR 45%) and tolerable. All patients were evaluable for toxicity and 14/17 also for response after 2 BELD cycles (total n. of cycles was 54). Criteria for response were just the same as those used by Young et al. A complete remission and a partial remission (2/14) have been observed at lymph nodal level, the unique sites of the disease in these two patients. Remission lasted 6 and 4 months, respectively. Two other patients showed a minimal response of 2 and 3 months duration (lymphonodal and cutis, respectively); 9 patients had stabilized disease of 5 months median duration. One case of progression of disease was observed. However, toxicity was relevant because of 2 early deaths after the first cycle, most probably therapy related, nausea and vomiting (82%), leukopenia (17%) and muscle rigors (11%).     

Oxaliplatin added to the simplified bimonthly leucovorin and 5-fluorouracil regimen as second-line therapy for metastatic colorectal cancer (FOLFOX6). GERCOR

For patients resistant to leucovorin (LV) and 5-fluorouracil (5-FU), the addition of oxaliplatin (85 or 100 mg/m2) to bimonthly LV-5-FU has given a response rate of 20-46%. The highest response rate has been observed with oxaliplatin 100 mg/m2 (FOLFOX2). The present phase II study (FOLFOX6) infused oxaliplatin (100 mg/m2) with LV (400 mg/m2) as a 2-h infusion on day 1, followed by bolus 400 mg/m2 and a 46-h infusion (2.4-3 g/m2) of 5-FU, every 2 weeks. Among the 60 patients treated, 16 (27%) had partial responses (95% confidence interval: 15-38), 27 (45%) had stable disease, 15 (25%) experienced disease progression and 2 (3%) had non-measurable disease. From the start of FOLFOX6, median progression-free survival was 5.3 months and median survival 10.8 months. From the 448 cycles analysed, NCI-CTC grade 3-4 toxicities per patient were: peripheral neuropathy 16%, nausea 7%, diarrhoea 7%, mucositis 5%, neutropenia 24%, thrombocytopenia 2%. Overall 26 (46%) patients experienced grade 3-4 toxicities. Because of toxicity, only 36% of the patients received > or = 90% of the scheduled oxaliplatin dose intensity. FOLFOX6 was active in pretreated patients resistant to LV-5-FU and is being investigated as first-line therapy. We are now investigating FOLFOX7, a regimen with a higher oxaliplatin dose intensity and a lower 5-FU dose.     

Cisplatin, 5-fluorouracil, mitomycin C, and concurrent radiation therapy with and without esophogectomy for esophageal carcinoma

Twenty-nine patients with carcinoma of the esophagus were treated with 5-fluorouracil (5-FU) (1000 mg/m2/d as a continuous intravenous [IV]infusion on days 1 through 4), cisplatin (100 mg/m2 IV on day 1), mitomycin C (10 mg/m2 IV on day 1), and concurrent radiation therapy (4500 cGy/4.5 wk). If no disease progression was observed, operable patients underwent surgery 4 to 6 weeks after completion of radiation therapy. A thoracotomy with a gastric pull-through operation was performed in the first six patients. Subsequently, a transhiatal ("blunt") esophagectomy was used. Twenty-five patients had squamous cell histology and four had adenocarcinoma. Of 25 patients with squamous cell carcinoma, 13 underwent esophagectomy. The clinical complete response rate was 61% (eight of 13 patients), with a pathologic complete remission documented in five of 13 patients (38%). The overall local tumor sterilization rate was 53% (seven of 13 patients). In the 12 patients who did not undergo surgery after chemoradiotherapy, four had a complete clinical response (33%) and five had a partial response (41%). Symptoms or signs of local disease recurrence or stricture were noticed in ten of 12 patients who did not undergo surgery (83%), compared with 28% of patients who underwent surgery. The median survival time of the group receiving surgery was 10 months, compared with 5 months for those who did not undergo operation (P = 0.027). Patients undergoing transhiatal esophagectomy had shorter postoperative hospital stays and fewer serious complications, compared with patients undergoing transthoracic esophagectomy. The use of chemoradiotherapy and transhiatal esophagectomy for esophageal carcinoma should be evaluated using alternative sequences of treatment (e.g., postoperative therapy) to reduce toxicity while maintaining local control of disease.     

Combination chemotherapy (5-fluorouracil, methyl-CCNU, mitomycin C) versus 5-fluorouracil alone for advanced previously untreated colorectal carcinoma. A phase III study of the Piedmont Oncology Association

One-hundred thirty eligible patients with advanced colorectal carcinoma who had received no prior chemotherapy were randomized to either methyl-CCNU, 70 mg/m2 orally every 6 weeks on day 1, mitomycin C, 10 mg/m2 intravenously every 6 weeks on day 1, and 5-fluorouracil (5-FU), 400 mg/m2 intravenously weekly--(MMF)--or 5-FU, 600 mg/m2 intravenously weekly (5-FU). One hundred twenty-six patients are evaluable for response. Of 62 patients treated with MMF, one (2%) achieved complete remission, and three (5%) attained partial remission. Of 64 patients treated with 5-FU, two (3%) achieved complete remission, and eight (13%) attained partial remission. The median survival for patients receiving MMF was 9.5 months compared with 10.3 months for patients receiving 5-FU. The survival distributions for the two regimens were not significantly different, either unadjusted or adjusted for pretreatment characteristics. Performance status and lactic dehydrogenase (LDH) were both significantly associated with survival. Patients with liver metastases only and normal liver function tests had a median survival of 19.8 months and a 40% response rate. This randomized phase III trial did not show any therapeutic advantage for MMF compared to 5-FU therapy alone in advanced colorectal cancer. In addition, hematologic toxicity was significantly greater with the combination (MMF) regimen.     

Paclitaxel, ifosfamide, nedaplatin (TIN) for patients with metastatic urothelial cancer

TIN (ifosfamide 1.5 g/m2 daily for 3 days, paclitaxel 175 mg/m2, and nedaplatin 70 mg/m2 on day 1) was administered to patients with metastatic urothelial cancer previously treated by platinum-based chemotherapy and repeated every 4 weeks. Four patients received maintenance therapy, which consisted of 5'-DFUR 800 mg/day orally for 12 weeks and 1 subsequent course of TIN. This therapy regimen was repeated for 2 years from initiation of TIN. Eleven of 12 patients (91.6%) demonstrated a major response (3 complete responses, 8 partial responses), with durations of response ranging from 3 to 20 months. Progression-free survival time was from 0 to 20 months (median 8 months). One-year progression-free survival rate was 45.8%. Overall survival time was from 2 to 20 months (median 10.5 months). One-year overall survival rate was 53.5%. Grade 3/4 hematologic toxicity involved neutropenia in 100% and thrombocytopenia in 33.3%. Febrile neutropenia was observed in 5 patients (41.6%). Grade 3 nonhematologic toxicity involved malaise in 15.3%. No patient discontinued this therapy because of complications. TIN is a potent, well-tolerated regimen for previously treated patients with urothelial cancer.     

Phase II study of weekly albumin-bound paclitaxel for patients with metastatic breast cancer heavily pretreated with taxanes

PURPOSE: Nanoparticle albumin-bound paclitaxel, a solvent-free, albumin-bound paclitaxel, demonstrated antitumor activity in patients with taxane-naive metastatic breast cancer (MBC). We examined albumin-bound paclitaxel (100 mg/m2 or 125 mg/m2 administered weekly) to determine the antitumor activity in patients with MBC whose disease progressed despite conventional taxane therapy. PATIENTS AND METHODS: Women with MBC that was previously treated with taxanes were eligible for participation. Taxane failure was defined as metastatic disease progression during taxane therapy or relapse within 12 months of adjuvant taxane therapy. Primary objectives were response rates (RRs) and the safety/tolerability of albumin-bound paclitaxel. RESULTS: Women were treated with albumin-bound paclitaxel 100 mg/m2 (n = 106) or 125 mg/m2 (n = 75) on days 1, 8, and 15 of a 28-day cycle. Response rates were 14% and 16% for the 100-mg/m2 and 125-mg/m2 cohorts, respectively; an additional 12% and 21% of patients, respectively, had stable disease (SD) > or = 16 weeks. Median progression-free survival times were 3 months at 100 mg/m2 and 3.5 months at 125 mg/m2; median survival times were 9.2 months and 9.1 months, respectively. Survival was similar for responding patients and those with SD. No severe hypersensitivity reactions were reported. Patients who developed treatment-limiting peripheral neuropathy typically could be restarted on a reduced dose of albumin-bound paclitaxel after a 1-2-week delay. Grade 4 neutropenia occurred in < 5% of patients. CONCLUSION: Albumin-bound paclitaxel 100 mg/m2 given weekly demonstrated the same antitumor activity as albumin-bound paclitaxel 125 mg/m2 weekly and a more favorable safety profile in patients with MBC that had progressed with previous taxane therapy. Survival of patients with SD > or = 16 weeks was similar to that of responders.     

A phase II trial of continuous infusion of 5-fluorouracil, mitoxantrone, and cisplatin for metastatic hepatocellular carcinoma

BACKGROUND: The aim of the current study was to evaluate the antitumor activity and toxicity of continuous infusion of 5-fluorouracil, mitoxantrone, and cisplatin (FMP therapy) in chemotherapy-naive patients with metastatic hepatocellular carcinoma (HCC). METHODS: Fifty-one patients with metastatic HCC who had not undergone previous systemic chemotherapy were enrolled. The therapy consisted of intravenous administration of 80 mg/m2 cisplatin and 6 mg/m2 mitoxantrone on Day 1 and continuous intravenous infusion of 450 mg/m2 5-fluorouracil per day on Days 1-5. The treatment was repeated every 4 weeks for a maximum of 6 courses with dose adjustments based on the observed toxic effects if there was no evidence of tumor progression or unacceptable toxicity. RESULTS: Of the 51 enrolled patients, 14 (27%) achieved a partial response (95% confidence interval, 16-42%) with a median duration of 7.6 months (range, 2.3-18.4 months). Twenty-seven patients (53%) showed no change and 9 (18%) had progressive disease. The median survival time, 1-year survival rate, and median progression-free survival time for all patients were 11.6 months, 44.3%, and 4.0 months, respectively. The main Grade 3 and 4 toxicities were leukocytopenia (67%), neutropenia (71%), thrombocytopenia (27%), and elevated levels of aspartate aminotransferase (37%) and alanine aminotransferase (41%). These symptoms were generally brief and reversible, with the exception of one treatment-related death due to acute hepatic failure. CONCLUSIONS: FMP therapy had significant antitumor activity with acceptable toxicity in patients with metastatic HCC.     

Cisplatin, epirubicin and 5-fluorouracil combination chemotherapy for recurrent carcinoma of the salivary gland

Nine patients (5 males, 4 females; median age, 62 years) with recurrent high-grade malignancies of major (7 cases) and minor (2 cases) salivary gland origin (4 adenoid cystic carcinomas, 2 adenocarcinomas, 2 poorly differentiated carcinomas, 1 mixed malignant tumor) were treated with cisplatin (60 mg/m2), epirubicin (50 mg/m2) and 5-fluorouracil (600 mg/m2) (CEF) by intravenous injections on the first day of a 21-day regimen. Previous therapy included surgery (1 case), radiotherapy (1 case), and surgery + radiotherapy (7 cases). There was 1 complete response (11.1%), 3 partial responses (33.3%), 2 unchanged lesions (22.2%) and 3 progressions (33.3%). Patients with local recurrence had a better response. Median remission duration was 7.5 months in CR + PR patients. Median overall survival was 8+ months; 14+ months for responders and 4 months for nonresponders. The major toxic effects were nausea/vomiting and alopecia; myelosuppression was less frequent and usually not severe.     

Sequential cis-platinum and fludarabine with or without arabinosyl cytosine in patients failing prior fludarabine therapy for chronic lymphocytic leukemia: a phase II study

Patients with chronic lymphocytic leukemia (CLL) who fail fludarabine (Fluda) therapy have a poor response to subsequent salvage regimens and a poor prognosis. This study was undertaken to determine the efficacy and toxicity of a cis-platinum, (cis-p)fluda and arabinosyl cytosine (ara-C) combination in patients who were refractory to fluda or had relapsed following prior fluda therapy for CLL. Forty-one patients who had progressive CLL were treated on study. Eleven patients (27%) were sensitive to fluda and thirty (73%) refractory prior to study entry. Therapy consisted of cis-p 100 mg/m2 continuous intravenous (i.v.) infusion over 4 days, fluda 30 mg/m2 i.v. over 15 minutes on Days 3 and 4 either given alone (PF) or with ara-C 500 mg/m2 i.v. over 1 hour on Day 4 (PFA). The median number of PF or PFA courses received was two. No patient achieved a complete response. Eight patients (19%) achieved a partial response (PR), 28 were taken off study with progressive or refractory disease and 5 had induction deaths. The overall median survival was 6 months, 15 months in responding patients, and 4 months in non-responding patients. Rai stage I-II patients had a median survival of 7 months and stage III-IV patients had a median survival of 3 months. Major toxicities (myelosuppression, sepsis, renal failure and tumor lysis syndrome) were frequent. In conclusion, it can be said that the PF and PFA regimens have equivalent modest activity in patients with progressive CLL following prior fluda therapy, predominantly among patients whose disease was sensitive to fluda at last prior exposure. Ara-C did not add to the activity of the cis-p/fluda combination in this study group.
