Calculation of received dose intensity for combinations of drugs using small-cell lung carcinoma treatment regimens as examples.

Programs are presented for the calculation of received dose intensity in combination chemotherapy regimens. These provide methods for determining the final dose intensity, the mean cumulative dose intensity together with its standard error, and other tabular and graphic summaries. Two ways of dividing patients into high and low received-dose-intensity groups are proposed. Methods are illustrated using data from Mid-Atlantic Oncology Program (MAOP) 2183, a phase III evaluation of a six-drug alternating combination vs a three-drug "standard" combination treatment for extensive small-cell lung cancer. Comparisons of received dose intensity with demographic and outcome variables are presented.
