ABSTRACT
BACKGROUND:
Surgical exploration remains the gold standard for evaluating the extension of disease and predicting resectability. A laparoscopy-based scoring model was developed by Fagotti and colleagues in 2006 and updated in 2015, based on the intraoperative presence or absence of some specific cancer features. The model proved an overall accuracy rate of 77% to 100% and is considered the reference test for assessing resectability in our institution.OBJECTIVE:
The primary aim of the study was to analyze the agreement between preoperative ultrasound examination and laparoscopic findings in assessing the extension of intraabdominal disease using 6 parameters described by Fagotti's score. STUDYDESIGN:
This was a prospective single-center observational study. Between January 2019 and June 2020, consecutive patients with clinical or radiological suspicion of ovarian or peritoneal cancer were assessed with preoperative ultrasound examination and assigned a score based on the 6 Fagotti score parameters (great omentum, liver surface, lesser omentum/stomach/spleen, parietal peritoneum, diaphragms, bowel disease). Presence of mesenteral retraction of the small bowel and miliary carcinomatosis on the serosa were also evaluated. Each parameter was correlated with laparoscopic findings. Concordance was calculated between ultrasound and laparoscopic parameters using Cohen's kappa.RESULTS:
Cohen's kappa ranged from 0.70 to 0.90 for carcinomatosis on the small or large bowel, supracolic omentum, liver surface, and diaphragms. Cohen's kappa test was lower for carcinomatosis on the parietal peritoneum (k=0.63) and on the lesser omentum or lesser curvature of the stomach or spleen (k=0.54). The agreement between ultrasound and surgical predictive index value (score) was k=0.74. For the evaluation of mesenteral retraction and miliary carcinomatosis, the agreement was low (k=0.57 and k=0.36, respectively).CONCLUSION:
The results of ultrasound and laparoscopy in the assessment of intraabdominal tumor spread were in substantial agreement for almost all the parameters. Ultrasound examination can play a useful role in the preoperative management of patients with ovarian cancer when used in dedicated referral centers.Palavras-chave
