Survival time, causes of death, and tumor/treatment-related morbidity in 100 women with ovarian cancer.

One hundred cases of ovarian cancer were studied at autopsy to determine the effect of morphologic and clinical factors on survival time, the primary cause of death, and tumor/treatment-related morbidity. The mean survival time was 19 months (0 to 174 months). Increasing neoplastic histologic grade and increasing clinical stage at diagnosis were each associated with decreased survival time. In grade I tumors, the mean survival time was 84 months; in grade II tumors, it was 18 months; and in grade III tumors, it was 12 months (P = .0008). Patients who presented in stage I or II had a better survival time (28 months) than those who presented in stage III or IV (15 months) (P = .02). The most common causes of death were disseminated carcinomatosis (48%), infection (17%), pulmonary embolus (8%), and combinations of infection and carcinomatosis (11%). In patients dying of infection, 43% had sepsis, 21% had pneumonia, and 25% had a combination of sepsis and pneumonia. Escherichia coli and Klebsiella were the most common pathogens identified postmortem. Intestinal obstruction (51%) and ureteral obstruction (28%) were the most common forms of tumor-induced morbidity. Bone marrow depression and resultant pancytopenia was the most common form of treatment-induced morbidity.
