OBJECTIVE: The aim of this study was to assess prognostic value of frailty for the prediction of surgical complications and mortality in women with end-stage ovarian cancer subjected to curative oncological surgery and its value for long-term follow-up.

PATIENTS AND METHODS: A total of 75 advanced-stage consecutive ovarian cancer patients who underwent elective surgery were investigated. The demographic data and clinical information related to the oncologic treatment were collected in the electronic and physical case records and included the following: age, ethnic group, comorbidities, staging of cancer, surgical procedure details, lymphadenectomy, American Society of Anesthesiology (ASA) grade, anesthetic technique, operative blood loss, operative time, and residual disease. A radiologist, who was blinded to patient outcomes, performed quantitative assessment of psoas muscle areas using the available computed tomography scan images at the caudal end of the third lumbar vertebra.

RESULTS: The mean age was 61.2 ± 18.2 years, and the percentage of patients over 65 years was 78%. Comorbidities (hypertension, diabetes, chronic obstructive pulmonary disease, renal insufficiency) were seen in 37 patients (49%). Histological types were adenocarcinoma in all patients (0) mostly serous adenocarcinoma (62%) and stage 3 (58%). According to psoas muscle measurement, 55 patients (73%) were nonsarcopenic and 20 patients (26%) were sarcopenic. Debulking procedures were performed on all patients. Also, bowel resection was applied in 40% of patients. Preoperative anesthetic examinations had shown that they were mostly ASA score 2 (44 patients). Moreover, 26 patients were ASA score 3. Generally, total operative time was between 121-240 minutes, and total blood loss was generally under 500 ml. Postoperative complications were seen in 26% of the patients. Non-surgical complications were observed in 14% of the patients, while non-surgical complications were observed in 12%. Length of the hospital stay >10 days was seen in 10 patients. Mortality was seen in 1 patient 30 days after operation. Nonsurgical complications (pneumonia, urinary tract infections, cardiac complications) were significantly higher in comparison to nonsarcopenic patients. However surgical complications were comparable between each group. Mortality after hospitalization and length of hospital stay were significantly higher in sarcopenic patients in comparison with the nonsarcopenic group.

CONCLUSIONS: The use of the value of the psoas muscle region is considered to be a method to predict the in-hospital mortality when there is an available abdominal CT scan that has already been performed for ovarian cancer patients with a significant comparable clinical and laboratory background. According to the findings, patients had worse surgical outcomes and higher postoperative nonsurgical complication rate when sarcopenic patients were compared to nonsarcopenic patients. Moreover, postoperative mortality and length of hospital stay were significantly higher in sarcopenic patients in comparison to non-sarcopenic group.
