The aim of our study was to assess the necessity to use an ultrasound score to evaluate patients with ovarian masses before surgery. At the Department of Gynaecologic Oncology of the University of Turin we enrolled over two years (form May 2007 to May 2009) 149 consecutive patients with ovarian mass considered for laparoscopic surgery. Patients demographics, clinical features, Ca125 values and surgical procedures were recorded. We collected ultrasound data: presence of uniloculate or multiloculate cysts, diameter , presence of papillary structures, liquid or solid content, regular or irregular wall, presence of papillary flow. Following the ultrasound exam all patients obtained a pre operative risk of malignancy and were scheduled in low and high risk class (benign vs malignant). Finally we obtained a pathological result for all ovarian masses. The mean age was 46.34 (range 17-79 years). The 73.82 percent (110/149) of patients presented a low risk mass and 26.17 percent a high risk mass. After surgery we obtained the following results: 104 benign masses with a negative ultrasound exam (true negative), 32 benign masses with positive exam (false positive), 7 malignant masses with positive exam (true positive), 6 malignant masses with negative ultrasound exam (false negative). The sensibility of the exam was 53% and the specificity was 76%. There is the necessity to create an ultrasound score to study all ovarian masses. We have already designed a prospective study to compare the result of an ultrasound score with the subjective ultrasound evaluation and to create an appropriate surgical approach.

Abstract
The aim of our study was to assess the necessity to use an ultrasound score to evaluate patients with ovarian masses before surgery. At the Department of Gynaecologic Oncology of the University of Turin we enrolled over two years (form May 2007 to May 2009) 149 consecutive patients with ovarian mass considered for laparoscopic surgery. Patients demographics, clinical features, Ca125 values and surgical procedures were recorded. We collected ultrasound data: presence of uniloculate or multiloculate cysts, diameter , presence of papillary structures, liquid or solid content, regular or irregular wall, presence of papillary flow. Following the ultrasound exam all patients obtained a pre operative risk of malignancy and were scheduled in low and high risk class (benign vs malignant). Finally we obtained a pathological result for all ovarian masses. The mean age was 46.34 (range 17-79 years). The 73.82 percent (110/149) of patients presented a low risk mass and 26.17 percent a high risk mass. After surgery we obtained the following results: 104 benign masses with a negative ultrasound exam (true negative), 32 benign masses with positive exam (false positive), 7 malignant masses with positive exam (true positive), 6 malignant masses with negative ultrasound exam (false negative). The sensibility of the exam was 53% and the specificity was 76%. There is the necessity to create an ultrasound score to study all ovarian masses. We have already designed a prospective study to compare the result of an ultrasound score with the subjective ultrasound evaluation and to create an appropriate surgical approach.
