Abstract

Objective. To prospectively estimate the agreement between a fellow in training in gynecologic oncology and a senior surgeon performing a laparoscopic score to describe peritoneal carcinosis diffusion in patients with advanced ovarian cancer. Design: Single-institutional non-inferiority trial. Setting. University hospital tertiary care center. Population. Ninety consecutive patients with primary advanced ovarian cancer. Methods. The patients underwent staging-laparoscopy by a fellow in gynecologic oncology and a senior surgeon, sequentially and blindly. Single laparoscopic parameters (omental cake, peritoneal and diaphragmatic carcinosis, mesenteric retraction, bowel stomach infiltration, superficial liver metastasis) and a comprehensive laparoscopic score (PIV) were assessed in each procedure and registered. Main outcome measures. No differences in the score discriminating performance for predicting optimal cytoreduction were observed between fellows' and seniors' evaluations. Results. The median number of staging laparoscopies performed by each fellow was 30 (range 28-32). The median score was 6 (0-10) for the fellows and 6 (0-14) for senior surgeons (p=ns). Results were superimposable in 57 of 90 patients (63.3%). Dividing the study period into two blocks, cases 1-45 and cases 46-90, differences were equally distributed over time (16.6 vs. 20%; p=0.9). The area under the curve of the receiver operating characteristic (ROC) curves for the score of fellows and seniors was 0.86 and 0.89, respectively (p=ns). Conclusions. The laparoscopic assessment of peritoneal cancer diffusion according to a laparoscopic score can reliably be carried out by a fellow in gynecologic oncology after 12 months' experience without significant differences from a senior surgeon's assessment.
