Surgical and Oncological Outcome of Robotic Surgery Compared With Laparoscopic and Abdominal Surgery in the Management of Locally Advanced Cervical Cancer After Neoadjuvant Chemotherapy.

OBJECTIVE: The primary aim is to evaluate the surgical and oncological outcome of robotic radical hysterectomy (RRH) plus pelvic lymphadenectomy in locally advanced cervical cancer (LACC) after neoadjuvant chemotherapy (NACT). The secondary aim is to compare the surgical and oncological results of RRH after NACT with a historical cohort of patients undergoing laparoscopic radical hysterectomy or abdominal radical hysterectomy plus pelvic lymphadenectomy for LACC after NACT. METHODS: We enrolled a total of 41 patients in this study with LACC undergoing RRH, who achieved a clinical partial or complete response to NACT. The surgical and oncological outcomes of 2 historical groups were compared: the laparoscopic group (41 patients) with the laparotomic group (43 patients). RESULTS: The median estimated blood loss, operative time, and length of hospital stay were statistically significant and in favor of the robotic group. No conversion to laparotomy in the robotic group was necessary. There were no significant differences between the 3-year overall survival and disease-free survival rates in the minimally invasive groups; nevertheless, the robotic group showed the same recurrence rate of laparoscopic in a short-interval follow-up. CONCLUSIONS: The robotic approach could be considered a feasible and safe alternative to other surgical options. Multicenter randomized clinical trials with longer follow-ups are necessary to evaluate the overall oncologic outcomes of this procedure.

Robotic single-site hysterectomy in low risk endometrial cancer: a pilot study.

BACKGROUND: To evaluate the feasibility and the safety of robotic single-site hysterectomy (RSSH) in low risk early endometrial cancer. METHODS: Patients with clinical low risk early endometrial cancer were enrolled onto a prospective cohort trial. All surgical procedures were performed through a single 2-2.5 cm umbilical incision, with a multichannel system consisting of a five-lumen port providing access for two single-site instruments (da Vinci Si Surgical System, Intuitive Surgical, Sunnyvale, CA), the 8.5 mm 3D HD endoscope, a 5/10 mm accessory port, and an insufflation adaptor. RESULTS: Between December 2011 and June 2012, a total of 17 patients were included in our pilot study. The median age of the patients was 64 years (range, 42-84 years), and median body mass index was 26.6 kg/m(2) (range, 18-52 kg/m(2)). One patient was excluded from the study as a result of pelvic metastasis during inspection of abdominal cavity, and another patient was converted to vaginal surgery as a result of problems of hypercapnia. The median docking time, console time, and total operative time was 8 min (range, 5-14 min), 48 min (range, 45-51 min), and 90 min (range, 70-147 min), respectively. The median blood loss was 75 mL (range, 50-150 mL). No laparoscopy/laparotomy conversion was registered. The median time to discharge was 2 days (range, 1-3 days). Neither intraoperative nor postoperative complications occurred. At a median of 7.5 months' follow-up, all patients were disease-free. CONCLUSIONS: RSSH is technically feasible in patients affected by low risk early endometrial cancer. Additional studies with gynecologic oncologic cases should be performed to explore the possible benefits of RSSH.

Robotic transperitoneal aortic lymphadenectomy in gynecologic cancer: a new robotic surgical technique and review of the literature.

BACKGROUND: Lymph node status is a prognostic factor for gynecologic cancer. We describe a new developing strategy for robotic transperitoneal aortic lymphadenectomy without relocating the robotic column or the patient. METHODS: Patients with histologically confirmed cervical cancer, early ovarian cancer, or endometrial carcinoma with suspected risk factors indicating aortic lymphadenectomy were eligible for the robotic transperitoneal aortic lymphadenectomy using the Da Vinci robotic system as part of the surgical treatment of gynecologic malignancies. RESULTS: The mean operating time was 224 min (range 160-300 min), and the mean console time for aortic lymphadenectomy was 43 min (range 30-75). The median hemoglobin fall was 1.3 g/dL range (0.8-2 g/dL), the median number of removed aortic lymph nodes was 12.5 (range 7-17), and the median length of the hospital stay was 2 days (range 1-4 days). We experienced an intraoperative complication, but no conversion to laparotomy was necessary. No patients received a blood transfusion. CONCLUSIONS: This initial experience demonstrates the feasibility of robotic aortic lymphadenectomy with good accuracy and safety without relocating the robotic column or the patient.

Robotic radical hysterectomy after neoadjuvant chemotherapy in locally advanced cervical cancer.

Neoadjuvant platinum-based chemotherapy (NACT) plus radical hysterectomy and pelvic lymphadenectomy has been demonstrated to be a valid alternative to chemoradiation in patients with advanced cervical cancer. Several publications have reported on the feasibility of robot-assisted laparoscopy in early cervical cancer. Herein is reported the case of a woman with locally advanced cervical cancer that was successfully treated using neoadjuvant chemotherapy followed by total robotic type C1 radical hysterectomy (TRRH) plus pelvic lymphadenectomy. The success of this approach, which is not the standard of care in this disease, suggests that additional studies should be performed in a selected population.

Diagnostic and prognostic validity of the human papillomavirus E6/E7 mRNA test in cervical cytological samples of HC2-positive patients.

The study aimed to assess the clinical utility in identifying CIN2 or worse (CIN2+), of the Pretect HPV-Proofer test for E6/E7 mRNA detection in Hybrid Capture 2 (HC2)-positive patients, who underwent colposcopy. In particular, the study analyzed the mRNA test performance as the third test in a subgroup of HC2+ patients with less severe than high-grade squamous intraepithelial lesions (HSIL-). We analyzed 464 cervico-vaginal samples by liquid-based cytology (LBC) and PreTect HPV-Proofer. Moreover 231 patients also had a biopsy at baseline and 75, with HSIL-, were followed up within 2 years by LBC, colposcopy, and histology when indicated. The highest sensitivity for CIN2+ belonged to the mRNA compared to LBC, at the HSIL+ threshold (72% vs. 58%), whereas the LBC showed the highest specificity and positive predictive value (PPV) (99 and 93% vs. 73 and 39%, respectively). Focusing on the 408 HSIL- patients, the mRNA positivity was significantly more associated with CIN2+ than CIN2- lesions (p < 0.0001). Moreover, among the 75 HSIL- followed up patients, the mRNA displayed high longitudinal Specificity (89%), even if the sensitivity and the PPV were low (50 and 20%, respectively). The present data suggest that the mRNA test may have a diagnostic and a potentially prognostic role in HC2+/HSIL- patients.
