Cis‐platinum therapy of previously treated head and neck cancer: The Southwest Oncology Group's two‐dose‐per‐month outpatient regimen

Abstract
The Southwest Oncology Group tested an outpatient Cis‐platinum regimen in patients with carcinoma of the head and neck. Courses which consisted to two doses, a week apart, were scheduled to be given at 4‐week intervals. Eighty‐nine poor risk head and neck cancer patients, who had received extensive prior therapy with surgery, radiation, and/or multiple drugs were studied. Sixteen (18% of all entered and 25% of the 65 fully evaluable) had objective tumor regression. The median duration of response was 136 days. Toxicity was moderate. Myelosuppression was minimal with only 3% of patients exhibiting leukocyte nadirs below 2,000 and less than 2% experiencing platelet counts below 50,000. Significant, but reversible, impairment of renal function occurred in 8% of patients. Individual susceptibility to such renal toxicity appears to have been predictable. This simple outpatient program with its effectiveness and minimal toxicity in poor risk patients deserves further utilization.
