Is there still a role for mitomycin-based combination chemotherapy in treating patients with nonsmall cell lung cancer? A single institution experience.

BACKGROUND: Mitomycin and irinotecan are widely used in the treatment of colorectal cancer, furthermore both of these drugs are active agents against nonsmall cell lung cancer and their combination has shown synergism in preclinical studies. The aim of the study was to evaluate the efficacy and safety of mitomycin- and irinotecan-based chemotherapy combination in patients with advanced nonsmall cell lung cancer progressing after previous antineoplastic therapies. METHODS: Thirty-one consecutive patients suffering from nonsmall cell lung cancer, who underwent mitomycin- plus irinotecan-based chemotherapy as salvage treatment after failure of at least two previous systemic treatments, were retrospectively identified in our database. Between September 2003 and March 2011, 31 patients with histologically proven stage IIIB or IV nonsmall cell lung cancer, received mitomycin 5 mg/m(2) on day 1 followed by irinotecan 150 mg/m(2) on day 2. Cycles were repeated at 2-week interval. RESULTS: A total of 164 cycles of treatment were given with a median of five per patient (range 1-10). The objective responses included partial response in 6 patients (19.3%), stable disease in 4 (13%), and progressive disease in 21 (67.7%). Median time to disease progression was 4 months, and median survival was 9+ months. Twelve patients (38%) reached 1-year survival. Grade 3-4 toxicities occurred in seven patients (22.5%), mainly myelosuppression (neutropenia, anemia, and thrombocytopenia), mucositis, and diarrhea. No treatment-related death was recorded. CONCLUSION: The mitomycin- and irinotecan-based combination chemotherapy seems to be tolerated and active in this subset of heavily pretreated patients with advanced nonsmall cell lung cancer. However, evaluation or recruitment of a larger number of patients would be needed to provide more adequate data on safety and activity of the described combination.

Initial experience with hepatic intraarterial fotemustine and interferon alpha 2b combination for treatment of liver tumors.

BACKGROUND: Locoregional treatments represent a good option for patients suffering from hepatocellular carcinoma (HCC) not eligible for resection or transplantation. Locoregional approaches include a wide spectrum of therapeutic methods and hepatic intra-arterial drug infusion is also considered. Fotemustine is a chemotherapy drug usually administered intravenously according to standard administration schedules. Interferon alpha 2b (IFNα2b), a biological response modifier conventionally administered by a systemic route, has been employed in the treatment of both virus-related hepatitis and HCC. Nonetheless, both drugs can also be infused into the hepatic artery. PATIENTS AND METHODS: We report on five patients with liver cancer, not suitable for conventional therapies, treated with hepatic intra-arterial administration of fotemustine in combination with IFNα2b. They received fotemustine at a dose of 30 mg/m(2) and IFNα2b at a starting dose of 2,000,000 IU (increasing up to 3,000,000 IU for subsequent administrations) weekly for three consecutive weeks, followed by two weeks of rest. RESULTS: Among the patients suffering from HCC, the first patient showed a partial response, two patients had almost stable disease and one patient was not assessable. A patient with an intrahepatic biliary tract cancer experienced disease progression. CONCLUSION: The therapeutic regimen used showed acceptable tolerability profiles and lack of life-threatening side-effects. Further evaluation with a larger patient cohort will be required to clarify if fotemustine and IFNα2b administered into the hepatic artery could be beneficial in treating patients with HCC.
