Comparison of perioperative morbidity in patients with ovarian malignancy undergoing radical cancer surgery with or without prior chemotherapy

Evaluation was undertaken of the effect of chemotherapeutic drugs on the perioperative morbidity of patients with ovarian malignancy undergoing radical surgery. Twenty patients who had received cytotoxic drugs pre-operatively (group I) were compared with 11 patients in whom radical surgery was the first line of treatment (group IT). Pre and post-operative cardiac, pulmonary, renal, hepatic and coagulation functions were compared in both groups, as well as the critical intra- and post-operative events like cardiac pump failure, respiratory dysfunction, rhythm disturbances, blood loss, etc. Demographic data, ASA status, biochemical and haematological parameters and cardiac ejection fractions were comparable in the two groups but patients in group I had significantly higher left ventricular end diastolic dimensions (P<0.01). A higher number of patients in group I had pre-operative respiratory and coagulation factor abnormalities but critical intra- and post-operative events in both groups were comparable. The surgical time was significantly (P<0.01) longer in group I (5.5+/-2.5 h) as compared to group II (4.5+/-1.5 h). One patient with extensive tumour spread and pre-operatively deranged coagulation profile (group I) died of disseminated intravascular coagulation in the post-operative period. It is concluded that patients with advanced ovarian malignancy, treated with cytotoxic drugs are more likely to have pre-operative cardiac, respiratory and coagulation abnormalities, which should be managed by thorough pre-operative evaluation and intensive intra- and post-operative monitoring.
