Salvage chemotherapy with CCNU and methotrexate for small cell lung cancer resistant to CAV/PE alternating chemotherapy.

CCNU and methotrexate were employed as salvage treatment in 34 small cell lung cancer patients resistant to CAV/PE alternating induction chemotherapy. In the 33 evaluable patients we observed an objective response rate of 21.2% and 3% complete response; median survival was 4 months with 2 patients alive 18 months from starting salvages chemotherapy. The treatment was well tolerated. CCNU and methotrexate has shown to be a moderately active and tolerable salvage treatment for small cell lung cancer after CAV/PE alternating first-line chemotherapy.
