Abstract

Summary Objective: The risk of metastatic ovarian tumor is significantly higher in case of women with a history of colorectal cancer. Additionally, the possibility of developing ovarian cancer due to congenital mutations in suppressor genes should be assessed. Design: The purpose of the study was to evaluate the clinical presentation and histopathology of adnexal tumors in case of female patients with a history of colorectal adenocarcinoma. Material and methods: A retrospective study on 13 women (each with a history of colorectal carcinoma, operated due to adnexal tumor between 2004 and 2007), has been conducted. Subject characteristics, ultrasound, CT, serum tumor markers levels, histopathology and findings at surgery were analyzed. Results: Time distance between colorectal cancer surgery and ovarian tumor operation – measured in months – was shorter in cases of malignant neoplasms (10.13 +/- 3.98) than in benign tumors (26.2 +/- 19.37). Ultrasound examination showed solid-cystic adnexal tumors in 8 malignant cases, and ovarian cysts in 5 benign conditions. The use of ultrasound with plasma levels of CEA, CA 19.9 and CA 125 improved the validity of the preoperative differentiation of ovarian masses. Total abdominal hysterectomy with bilateral salphingo-oophorectomy was performed in eleven cases. Unilateral adnexectomy only took place in one case of benign tumor and in one case of disseminated neoplasmatic disease. Conclusions: When evaluating a patient with an adnexal tumor, a history of malignancy strongly suggests a metastatic nature. The use of ultrasound associated with plasma levels of Ca 125, Ca 19-9 and CEA, represents a useful method of preoperative assessment of ovarian tumors.
