Objective: To describe the rate of port-site metastasis in patients who underwent robotic surgery for suspected gynecological malignancy.
Methods: Using a prospective database, we identified all patients who underwent robotic surgery performed by the Gynecologic Oncology service at 1 institution between December 2006 and March 2010. Records of patients with confirmed malignancy were reviewed for clinicopathological data and information about port-site metastasis.
Results: One hundred eighty-one patients met the inclusion criteria. The median age was 55.4 years (range, 19-82 years), and the median body mass index was 29.6 kg/m2 (range, 17.9-70.7 kg/m2). Port-site metastases were detected in 2 patients (1.1%) at 3 weeks (patient 1) and 11 months (patient 2) after surgery. Patient 1 underwent surgery for an adnexal mass, and pathological examination revealed gallbladder adenocarcinoma metastatic to the ovary. She had a recurrence in the right lateral abdominal wall robotic trocar site with concurrent metastases in the gallbladder fossa and liver. Patient 2 was diagnosed with adenocarcinoma of unclear (cervical vs endometrial) origin. Imaging showed metastases in pelvic and para-aortic lymph nodes. She underwent laparoscopy and was found intraoperatively to have gross disease on the right ovary. The patient underwent right salpingo-oophorectomy and chemoradiation. She had residual disease in the cervix and subsequently underwent robotic hysterectomy and left salpingo-oophorectomy. Pathological examination revealed endometrial cancer. She had a recurrence at the transumbilical trocar site concurrent with retroperitoneal lymphadenopathy and carcinomatosis. There were no cases of isolated port-site metastasis.
Conclusions: The rate of port-site metastasis after robotic surgery in women with gynecological cancer is low and similar to the rate for laparoscopic procedures.
- Port-site metastasis/recurrence
- Ovarian cancer
- Cervical cancer
- Uterine cancer
