title: Pretreatment prognostic factors in carcinoma of the uterine cervix: a multivariable analysis of the effect of age, stage, histology and blood counts on survival.
abstract: From January, 1953 through December, 1977, 910 previously untreated patients with invasive carcinoma of the uterine cervix (Stages IB-IVB) were seen at Yale-New Haven Medical Center and affiliated hospitals. An extensive retrospective analysis was undertaken in an attempt to identify prognostically significant pretreatment factors. The patients studied were uniformly staged according to the current FIGO recommendations and the majority of patients had been treated under standardized protocols combining external beam radiation therapy and intracavitary radium. Pretreatment parameters, including prior medical illnesses, gross tumor characteristics, histology, and blood parameters were studied, employing stepwise Cox regression analyses to identify the possible effects of all factors and all two-way interactions among factors on survival, disease-free survival and freedom from local-regional failure, controlling for stage of disease. FIGO stage, patient age at diagnosis, pretreatment neutrophil count and hematocrit, uterine position, prior subtotal hysterectomy, histology, history of diabetes mellitus and number of pregnancies were all found to have prognostic significance. When other factors including stage of disease were controlled for, increased tumor size was associated with decrease disease-free survival and local-regional control rates.
