title: An active chemotherapy regimen for squamous cell lung cancer.
abstract: A new concept of chemotherapy scheduling was evaluated in 20 patients with inoperable squamous cell lung cancer. The complete plus partial response rate was 85%, with 15% complete responses. The drugs utilized included vinblastine, bleomycin, methotrexate, 5-FU, cisplatin, and leucovorin. The hypothesis leading to the chosen drug schedule was that impaired rbc deformability (RBCD) found in cancer patients may produce stasis of flow in tumor capillary beds and decrease drug delivery to cancer cells. Drug schedules were designed to take advantage of chemotherapy-induced improvement in RBCD. After an initial drug treatment, a second treatment was given when RBCD increased at least 25% over pretreatment values (usually 4-6 days after the first chemotherapy dose). Drug doses were weighted so that more drug was given when RBCD was greatest. Treatment toxicity was predominantly hematopoietic and renal. This type of chemotherapy approach opens up new avenues of investigation in squamous cell cancer and other common neoplasms.
