Ovarian cancer diagnosis and treatment

The incidence and risk factors of lymphocele development after pelvic lymphadenectomy were evaluated and its management investigated.This retrospective study was carried out on 264 patients who received a pelvic lymphadenectomy, between March 1999 and February 2003, due to gynecologic cancer. The patients were classified into two groups; the lymphocele (n=50) and non-lymphocele groups (n=214), as confirmed by ultrasonography, CT scan and MRI. Each group was compared by cancer type and stage, BMI, preoperative Hb, use of pre/postoperative chemotherapy or radiotherapy, number of resected pelvic lymph nodes and the volume of postoperative drainage from a Hemovac pelvic drain.Of the 264 patients tested, 15 of 105 cervical cancer (14%), 22 of 115 ovarian cancer (19%) and 11 of 40 endometrial cancer patients (27%), a total of 50 patients (18%), developed lymphoceles. In the lymphocele group (n=50), 13 patients were diagnosed with complicated lymphocele. The BMI and number of resected pelvic lymph nodes were found to be higher in the lymphocele than in the non-lymphocele group (23.94+/-3.38 vs. 22.52+/-3.00, p=0.00 and 26.80+/-14.82 vs. 22.96+/-10.18, p=0.03, respectively), and showed statistical significance. The occurrence of lymphoceles was lower without postoperative radiotherapy (p=0.01).Among the 264 patients, a total of 50 patients (18%) developed lymphoceles. The BMI and number of resected lymph nodes were higher in the lymphocele group, and the use of postoperative radiotherapy was associated with a higher risk of lymphoceles. Thirteen of the 50 patients that developed lymphoceles (n=50) required treatment for lymphocele-related complications.
