Mitoxantrone, fluorouracil plus L-leucovorin, and vinorelbine in pretreated advanced breast cancer.

The combination chemotherapy including mitoxantrone, fluorouracil and leucovorin has proven to be effective and well-tolerated in advanced breast cancer (ABC). No data are available on the association with navelbine, a new vinka alkaloid, which has demonstrated high activity in ABC. The trial was designed to evaluate feasibility and efficacy of the association of vinorelbine to mitoxantrone, fluorouracil and L-leucovorin in patients who failed a previous regimen for ABC or who relapsed within 6 months of adjuvant chemotherapy. The schedule was as follows: mitoxantrone 6 mg/m2 days 1 and 8; L-leucovorin 250 mg/m2 days 1 and 8, fluorouracil 600 mg/m2 days 1 and 8, vinorelbine 25 mg/m2 days 1 and 8, cycles being repeated every 21 days. Twenty-five patients were enrolled and are evaluable for response and side effects. One hundred cycles of therapy have been delivered (median/patient, 4 cycles). In 41 cycles a delay was required and in 38 cycles it was necessary to administer granulocyte colony-stimulating factor for neutropenia. Seven partial remissions (28%; 95% confidence interval, 12-49%), 10 stabilizations of disease and 8 progressions were observed. Although grade 4 neutropenia was observed in 44% of the patients, no grade 3-4 infections were observed. Nonhematologic toxicities were mild or moderate and included alopecia, mucositis and phlebitis. In conclusion, the schedule employed, although correlated with a moderate activity, does not seem to be superior to other regimens with mitoxantrone, fluorouracil, and leucovorin.

A dose-escalating study of carboplatin combined with vinorelbine in non-small-cell lung cancer.

Platinum compounds and vinorelbine have been demonstrated to be active in non-small-cell lung cancer (NSCLC). The aims of the study were to assess tolerability and feasibility of increasing doses of carboplatin (level 1: 300 mg/ m2 on day 1, level 2: 350 mg/m2 on day 1, level 3: 400 mg/m2 on day 1) in combination with a fixed dose of vinorelbine (25 mg/m2 on days 1 and 8) in advanced NSCLC. Forty-two patients entered the study and were evaluable for toxicity and response. The patients were not treated using systemic chemotherapy, had TNM stage IIIB-IV, performance status ECOG 0-2, and their median age was 62 (range 41-70) years. The number of patients evaluable for each dose level was 14. A total of 138 (median 3) courses was administered. Nonhematologic side effects included grade I-II mucositis (9%), neurotoxicity (6%), and infections (4%). Myelotoxicity was manageable and generally of short duration, with 19% of the patients having grade III-IV neutropenia. No significant difference was observed for the three treatment groups. No drug-related death was observed. An objective remission was observed in 10 patients (24% response rate; 95% confidence interval 12-39%), with 5 responses in 14 patients treated with the 400-mg/m2 dose. In conclusion, the combination of carboplatin at a dose of 400 mg/m2 on day 1 and vinorelbine at a dose of 25 mg/m2 on days 1 and 8 can be safely administered as first-line cytotoxic therapy in advanced NSCLC and warrants further evaluation.

Pain at tumor site after vinorelbine injection: description of an unexpected side effect.

AIMS AND BACKGROUND: Vinorelbine is a new semisynthetic vinka alkaloid that has demonstrated good tolerability and interesting activity in a large spectrum of solid tumors. It was the aim of this paper to report the presence of a rarely documented side effect. METHODS: In our experience, 135 patients were treated with vinorelbine during the period 10/92 to 11/94 for a total of 1080 cycles. In 26% of the cycles, vinorelbine was administered in monochemotherapy and in 74% in polychemotherapy regimens. The dose of vinorelbine, administered in a weekly schedule, was 25 mg/m2 in 109 patients and 30 mg/m2 in 26 patients. In general, no analgesic premedication was used. Sixty-five patients had lung cancer, 45 had breast cancer, and 25 miscellaneous cancer. Only 4 patients had a previous history of neurotoxicity. RESULTS: Ten patients (7%) had pain in the tumor site within a few minutes of the vinorelbine injection. According to WHO grade, 5 cases had moderate and 5 severe pain. Pain was always reversible. In 5 cases ketorolac was administered after pain detection with resolution of the symptoms; in 4 cases it was necessary to deliver buprenorphine. One patient was admitted to the coronary unit because a myocardial infarction was suspected after retrosternal pain and required i.v. morphine. Seven cases refused to continue the treatment, and 3 cases had no further problem after ketorolac premedication. CONCLUSIONS: Although rare, the presence of severe pain after vinorelbine injection may adversely affect the treatment course. Such data are helpful in the recognition and management of this reversible side effect.

Clinical development of new fluoropyrimidines: a major improvement in colorectal cancer treatment?

AIMS AND BACKGROUND: Colorectal cancer represents an increasing problem and is responsible for about 16,000 deaths per year in Italy. Fluorouracil represents the most widely used agent, but therapeutic responses have remained consistently discouraging. The overall response rates for fluorouracil as a single agent range from 5% to 15%, and the addition of biochemical modulators, although able to improve response rate, has not been shown conclusively to prolong survival. METHODS: In recent years, several new compounds characterized by a high therapeutic index, optimal absorption through the gastrointestinal tract when administered orally and selective hepatic metabolization have been synthesised. In this review we analyzed published data on new fluoropyrimidines in an attempt to better define their role and to evaluate any significant improvement over fluorouracil. RESULTS: Although no sure advantage over fluorouracil has been detected, interesting results have been reported for fluorouracil analogs with alternative routes of administration such as oral or intra-arterial chemotherapy. CONCLUSIONS: Further studies, possibly randomized, should also measure quality of life and treatment-related costs in order to define their real advantage over fluorouracil in the palliation of advanced colorectal cancer.

Megestrol acetate in unresectable hepatocellular carcinoma.

AIMS AND BACKGROUND: No consolidated medical treatment has yet been established for unresectable hepatocellular carcinoma (HCC). A possible interference of hormones in the pathogenesis and cellular growth of HCC has been suggested. METHODS: To evaluate the activity and tolerance of progestins in HCC, patients were treated with megestrol acetate orally at a dose of 160 mg daily until progression of disease or grade III-IV toxicity was observed. RESULTS: Eleven patients entered the study and were assessable for response and side effects. Median duration of treatment was 80 days (range 60-150). No major responses were observed, 4 patients had stabilization of disease for at least 2 months, and 7 had progressive disease. Median time to disease progression was 3 months (range 2-5). Three patients required interruption of treatment because of toxicity (2 patients had worsening of concomitant diabetes and 1 patient had gastric bleeding). CONCLUSIONS: The results of the present study suggest that hormone therapy with megestrol acetate has no significant role in HCC.

Surgery followed by intracavitary plus systemic chemotherapy in malignant pleural mesothelioma.

AIMS AND BACKGROUND: Malignant mesothelioma is associated with a median survival of 4 to 12 months. Data from the literature indicate that single modality treatment (surgery or intrapleural and/or systemic chemotherapy) does not significantly affect survival. METHODS: We therefore evaluated a combined approach consisting of surgery (pleurectomy + diaphragmatic or pericardial resection), intrapleural chemotherapy with cisplatin (100 mg/m2) and cytarabine (1,000 mg/m2) for 4 h immediately after pleurectomy, and systemic chemotherapy consisting of epirubicin (60 mg/m2) and mitomycin-C (10 mg/m2) day 1 every 4 weeks for 4 cycles. RESULTS: Twenty patients were enrolled in the study and were evaluable. Thirteen cases had residual gross disease after pleurectomy and 7 patients only minimal disease. Median time to disease progression was 7.4 months, and median survival was 11.5 months (range, 2-25+). No treatment-related death have been observed. Side effects after intracavitary chemotherapy included renal toxicity, anaemia and pain. Myelosuppression and alopecia were recorded during systematic chemotherapy. CONCLUSIONS: The results of the study indicate that the schedule is feasible, with encouraging results in terms of survival for patients with minimal residual disease after surgery.

Response to chemotherapy of brain metastases from malignant pleural mesothelioma.

Brain metastases represent an uncommon complication in malignant pleural mesothelioma. A 55-year-old male suffering from malignant mesothelioma and pretreated with intracavitary chemotherapy and radiotherapy was submitted to systemic chemotherapy including lomustine, carboplatin, vinorelbine, fluorouracil and folates after diagnosis of bilateral cerebral deposits. The patient had an impressive response to chemotherapy, with complete regression of related symptoms. This case report represents the first on response to chemotherapy of brain metastases from mesothelioma. It points out that chemotherapy should be further explored in this subset of patients.

Phase II study of oral L-leucovorin, 120-hour fluorouracil infusion and carboplatin in advanced pancreatic cancer.

BACKGROUND: No effective chemotherapy has been developed for patients with metastatic pancreatic cancer. Encouraging results have been reported with the combination of cisplatin and fluorouracil infusion. The aim of the study was to test the activity of oral L-leucovorin, carboplatin and fluorouracil infusion in untreated pancreatic cancer patients. PATIENTS AND METHODS: Patients with advanced pancreatic carcinoma were treated with carboplatin (300 mg/m2 on day 1), L-leucovorin (5 mg/m2 twice a day on days 1-5), and fluorouracil (1,000 mg/m2 as a 120-hr infusion on days 1-5), cycles being repeated every 21 days. RESULTS: Nine patients were included and were assessable for response and side effects. All patients had measurable disease and an ECOG performance status of 0-2. No patient achieved partial remission, 3 had stable disease, and 6 progressive disease. Median time to progression was 2 months (range, 2-8), and median survival was 4 months (range, 3-12). Toxicity consisted of mucositis, diarrhea and neutropenia. CONCLUSIONS: Patients with metastatic pancreatic carcinoma do not benefit from this treatment schedule.

Intermittent continuous infusion of fluorouracil and low-dose oral leucovorin in pretreated breast cancer: a pilot study.

AIMS AND BACKGROUND: There is evidence that fluorouracil (FU), when administered by protracted venous infusion, has antitumor activity in pretreated breast cancer. The aims of the study were to assess, in a population of heavily pretreated breast cancer patients (> or = 2 lines of chemotherapy previously administered), the feasibility and activity of a new combination of oral L-leucovorin and continuous FU infusion. METHODS: Patients were treated with the following combination: oral L-leucovorin, 5 mg/m2 days 1 through 14, plus FU, 250 mg/m2 days 1 through 14, with cycles repeated every 21 days. RESULTS: Since November 1994, 22 patients have entered the study and 20 are assessable for response and side effects. Major patient characteristics were: ECOG performance status, 0-2; median age, 56 years (range, 41-70); sites of metastasis, bone 9, lung 8, liver 2, pleura 7; 2 or more metastatic sites, 18. A total of 74 cycles has been administered (median/patient, 3 cycles). Five partial remissions (25%), 4 disease stabilizations and 11 disease progressions have been observed. Median time to progression was 3 months (range 1.6+). Grade I-II mucositis was observed in 8 patients and grade III-IV in 6 patients. Other side effects have included diarrhea and thrombocytopenia. CONCLUSIONS: The schedule has demonstrated moderate activity in heavily pretreated breast cancer, with mucositis as the dose-limiting toxicity.

Mitomycin C and vinorelbine in pretreated breast cancer.

AIMS AND BACKGROUND: Vinorelbine, a new semi-synthetic vinca alkaloid, has demonstrated high activity as a single agent in pretreated metastatic breast cancer. PATIENTS AND METHODS: To evaluate the activity of the combination vinorelbine-mitomycin C and to reduce the incidence of side effects, in particular myelotoxicity, patients with metastatic breast cancer pretreated with 1 or more chemotherapy regimens for metastatic disease were treated according to the following schedule: mitomycin C, 10 mg/m2 day 1, and vinorelbine, 25 mg/m2, days 1, 8 and 15, every 28 days. RESULTS: Twenty-seven patients were enrolled and were evaluable for activity and side effects. A total of 157 cycles were delivered (median 5 cycles per patient). There were 10 partial remissions (37%; 95% confidence interval 20-59%), 5 instances of stable disease and 12 of disease progression. Grade III-IV toxicity was mostly hematological and included thrombocytopenia (4%) and neutropenia (42%). CONCLUSION: Our results indicate that the combination of mitomycin C and vinorelbine has moderate activity in pretreated breast cancer.

Activity and tolerability of courses of intra-arterial chemotherapy followed by chemoembolization in unresectable hepatocellular carcinoma.

AIMS AND BACKGROUND: We previously reported encouraging response rates and survival with combined intra-arterial (i.a.) chemotherapy and chemoembolization in unresectable hepatocellular carcinoma. We therefore evaluated a new program combining three courses of i.a. chemotherapy with chemoembolization administered every 28 days. PATIENTS AND METHODS: The treatment regimen consisted of L-leucovorin (100 mg/m2 i.v.), fluorouracil (800 mg/m2 i.a.), and carboplatin (250 mg/m2 i.a.). Chemoembolization with mitoxantrone (10 mg/m2) plus ethiodized oil and gelatin sponge was performed immediately after. The same treatment was given every 28 days for 3 times. RESULTS: Twenty-eight patients entered the study and were assessable for response and side effects. There were 24 males and 4 females (median age, 68 yrs; range, 42-75). TNM stage was II-III in 20 and IVA in 8; 17 were Child's A and 11 Child's B. Baseline alpha-fetoprotein was elevated in 15, and there was cirrhosis in 23. Twelve patients had a partial response (43%; 95% confidence interval, 24-63%), 13 had stabilization, and 3 progressive disease. Median survival was 16.6 months (range, 2-24). Sixteen patients had grade I-II pain and 14 grade I-II fever. CONCLUSIONS: Our results indicate that the regimen is safe and well tolerated. Despite 43% objective remissions, our results do not seem better than those obtained with less intensive regimens.
