BOSTON – Laparoscopic staging of patients with uterine papillary serous carcinoma is a safe alternative to open staging and may offer some advantages, according to findings presented at the annual Minimally Invasive Surgery Week.
“Traditionally, serous papillary cancer has been treated different than the other endometrial cancers, the reason being is that it tends to behave more like ovarian cancer,” Jeanette Voice, MD, of Richmond University Medical Center in Staten Island, N.Y., said at the meeting, which was held by the Society for Laparoendoscopic Surgeons. “Patients with serous papillary cancer tend to be older [so] these patients may benefit from a less invasive surgical approach.”
Dr. Voice and her coinvestigators conducted an 8-year retrospective study of laparoscopic and open-staged cases treated from March 2007 through May 2015. Initially, 59 patients with pathology-confirmed uterine papillary serous carcinoma were identified over that time period, and were divided into two cohorts: one receiving open surgery (37 patients) and one receiving laparoscopic surgery (22 patients).
Median age, body mass index, and prior abdominal surgery rate were not significantly different between the two cohorts.
In terms of intraoperative factors, median operative times for the open and laparoscopic cohorts were similar: 196 minutes versus 216 minutes, respectively (P = .561). Similarly, the number of pelvic lymph node dissections and rate of omentectomy were also not significantly different: 18 nodes (open) versus 16 nodes (laparoscopic) (P = .96), and 100% (open) versus 91% (laparoscopic) (P = .08).
However, laparoscopic patients had more favorable median estimated blood loss (310 mL versus 175 mL, P = .048) and shorter hospital stays (4 days versus 1 day, P less than .042).
Laparoscopic patients also achieved more robust debulking to zero centimeter residual disease, with 90.5% of patients achieving it versus 65.7% of those in the open surgery cohort, but the difference was not statistically significant (P = .1).
In terms of postoperative adjuvant therapy – brachytherapy, external beam radiation, and chemotherapy – there were no significant differences in outcomes between the two cohorts. Recurrence rates were also similar, with nine recurrences in the open cohort and eight recurrences in the laparoscopic cohort. The estimated 36-month progression-free survival rates were “almost identical,” with 55.3% in the open cohort versus 53.3% in the laparoscopic (P = .727), according to Dr. Voice.
Postoperative complications were more common in the open surgery cohort (29.7%), compared with 13.6% in the laparoscopic cohort, but no statistically significant difference was found between them (P = .16).
Dr. Voice did not report information on financial disclosures.
