The new surgical robot Hugo™ RAS for total hysterectomy: a pilot study.

Background: With the rising popularity of robotic surgery, Hugo™ RAS is one of the newest surgical robotic platforms. Investigating the reliability of this tool is the first step toward validating its use in clinical practice; and presently there arelimited data available regarding this. The literature is constantly enriched with initial experiences, however no study has demonstrated the safety of this platform yet. Objectives: This study aimed to investigate its reliability during total hysterectomy. Materials and Methods: A series of 20 consecutive patients scheduled for minimally invasive total hysterectomy with or without salpingo-oophorectomy for benign disease or prophylactic surgery were selected to undergo surgery with Hugo™ RAS. Data regarding any malfunction or breakdown of the robotic system as well as intra- and post-operative complications were prospectively recorded. Results: Fifteen of the twenty patients (75.0%) underwent surgery for benign uterine diseases, and five (25.0%) underwent prophylactic surgery. Among the entire series, an instrument fault occurred in one case (5.0%). The problem was solved in 4.8 minutes and without complications for the patient. The median total operative time was 127 min (range, 98-255 min). The median estimated blood loss was 50 mL (range:30-125 mL). No intraoperative complications were observed. One patient (5.0%) developed Clavien-Dindo grade 2 post-operative complication. Conclusions: In this pilot study, Hugo™ RAS showed high reliability, similar to other robotic devices. What is new?: Present findings suggest that Hugo™ RAS is a viable option for major surgical procedures and deserves further investigation in clinical practice.

The first European gynaecological procedure with the new surgical robot Hugo™ RAS. A total hysterectomy and salpingo-oophorectomy in a woman affected by BRCA-1 mutation.

Background: The benefits of minimally invasive surgery are well known in gynaecology. Robotic-assisted surgery has gained widespread acceptance within the surgical community and seems to be the most rapidly developing sector of minimally invasive surgery. Objectives: This video shows the salient steps of total hysterectomy with new robotic technology, Hugo™ RAS. The objectives were to introduce and demonstrate the feasibility, efficacy, and safety of this new advanced device. Materials and Methods: A sixty-two years-old woman affected by BRCA-1 mutation underwent the first European gynaecological surgical procedure using the new surgical robot Hugo™ RAS in the Division of Gynecologic Oncology, Fondazione Policlinico Universitario A. Gemelli IRCCS, Rome, Italy. Main Outcomes measures: Docking and operative times. Results: The docking time was 6 minutes and the total operative time was 58 minutes. There were no system errors and faults in the robotic arms. The surgeon found no friction or rasping in the arms. The estimated blood loss was 30 mL. No intraoperative complications were recorded. Conclusion: Gynaecological surgery with Hugo™ RAS seems feasible, safe and effective as shown by initial experiences in urological surgery. A larger case series would confirm the current experience and determine whether this technology could offer any additional benefit.

Impact of surgeon learning curve in minimally invasive radical hysterectomy on early stage cervical cancer patient survival.

Background: Recently, it has been sustained that only surgeons skilled in minimally invasive radical hysterectomy (MI-RH) could provide valuable oncological outcomes in early-stage cervical cancer. Still, literature lacks data correlating surgeon experience with patient survival rate. We aimed to investigate the impact of surgeon training on this rate. Methods: This is a retrospective study of 243 early-stage cervical cancer treated with MI-RH. Multiple regression analyses were undertaken to investigate the impact of the surgeons learning curve, according to the number of MI-RH, on patients prognosis. Results: A steady trend of reduction in disease recurrence risk is associated with increased surgeon experience. The peak of the learning curve was shown at the 19th MI-RH (hazard ratio of disease-free survival: 0.321; 95%CI: 0.140-0.737; p= 0.007). The 3 years disease-free survival that a surgeon could provide to patients is significantly lower at the beginning of his/her learning path comparing to what he/she could guarantee once adequate experience had been achieved (75.4% and 91.6% respectively, p=0.005). Surgeon experience appears to be an independent prognostic factor. Conclusion: The experience that a surgeon can achieve practicing in MI-RH significantly influences oncological outcomes of early-stage cervical cancer patients. Future studies comparing minimally invasive and open surgery should take this into account. It would be advisable that the scientific community precisely establishes the minimum training required in the field of MI-RH for early-stage cervical cancer.

Secondary cytoreductive surgery in patients with isolated platinum-resistant recurrent ovarian cancer: a retrospective analysis.

OBJECTIVE: To analyze the impact of secondary cytoreductive surgery (SCS) on survival outcome in a retrospective series of isolated platinum-resistant recurrent ovarian cancer. METHODS: We evaluate a consecutive series of 268 ovarian cancer patients with platinum-resistant relapse. Isolated recurrence was defined as the presence of a single nodule, in a single anatomic site, and was observed in 27 cases (10.1%). In all women the presence of isolated relapse was assessed at radiological evaluation, and surgically confirmed in the SCS group. RESULTS: Among the 27 patients with isolated recurrence, 16 (59.3%) received chemotherapy alone, and 11 (40.7%) complete SCS followed by non-platinum based chemotherapy. No significant differences were observed in the distribution of baseline clinico-pathological characteristics, pattern of recurrent disease, duration of PFI, and type of salvage chemotherapy between the two groups. In the SCS group, 6 patients (54.5%) showed isolated peritoneal relapse and 5 women (45.4%) showed isolated lymph nodal recurrence, and were treated with peritonectomy and lymphadenectomy, according with site of relapse. Two post-operative complications (18.2%) occurred: asymptomatic lymphocele and groin wound dehiscence. SCS significantly prolonged median time to first progression (12 months vs 3 months; p-value=0.016), median time to second progression (8 months vs 3 months; p-value=0.037), and post-relapse survival (PRS) (32 months vs 8 months; p-value=0.002). Residual tumor at 1st surgery (X(2)=5.690; p-value=0.017), duration of PFI (X(2)=5.401; p-value=0.020), and complete SCS (X(2)=4.250; p-value=0.039) retains independent prognostic role for PRS in multivariate analysis. CONCLUSIONS: SCS prolongs PRS compared to chemotherapy alone in isolated platinum-resistant recurrent ovarian cancer.

Fertility-sparing surgery in ovarian cancer extended beyond the ovaries: a case report and review of the literature.

BACKGROUND: Much attention has been recently focused on the role of fertility-sparing surgery in patients with ovarian cancer. However, few data are currently available on the feasibility of conservative approaches in women with disease extending beyond the ovaries. AIM: This review article aims at summarizing the oncologic and obstetric outcome of patients with stage II-III ovarian cancer treated with fertility-sparing surgery. We also describe a successful conservative management of a stage IIC endometrioid ovarian carcinoma. METHODS: A literature search through Medline was carried out to locate published articles using the following keywords for selection: 'Fertility-sparing surgery and ovarian cancer'. From every single case series, we retrieved data on patients with stage II-III disease submitted to conservative surgery. RESULTS: We identified 21 patients with stage II-III disease receiving fertility-sparing surgery. Recurrent disease was observed in 9 women (42.8%), and 5 (23.8%) of them died of disease. In contrast, a successful obstetric outcome has been reported in 3 cases (14.2%). CONCLUSIONS: Radical surgical staging remains the standard of care for all women with stage II-III disease. A fertility-sparing approach may be considered only in the presence of a favorable histology and a very strong fertility desire.

Timing and pattern of recurrence in ovarian cancer patients with high tumor dissemination treated with primary debulking surgery versus neoadjuvant chemotherapy.

PURPOSE: To compare the timing and pattern of recurrence in patients with advanced ovarian cancer (AOC) receiving primary debulking surgery (PDS) versus neoadjuvant chemotherapy (NACT) followed by interval debulking surgery (IDS). METHODS: We retrospectively evaluated a consecutive series of 175 stage IIIC-IV epithelial ovarian cancer patients, with diffuse peritoneal carcinomatosis documented at initial surgical exploration. Forty patients received complete PDS, and the remaining 135 were treated with NACT followed by IDS with absent residual tumor after surgery. RESULTS: No differences were observed in the distribution of clinical pathological characteristics at the time of diagnosis between the two groups. The median follow-up was 31 months (range 9-150 months). We observed 20 (50.0%) recurrences in the PDS group compared to 103 (76.3%) in the IDS group (p = 0.001). Duration of primary platinum-free interval (PFI) was shorter in IDS compared to PDS group (13 vs. 21 months, respectively; p = 0.014). A significantly higher percentage of patients in the IDS group experienced platinum-resistant recurrences (35.9 vs. 5.0%; p = 0.006) and carcinomatosis at the time of relapse (57.3 vs. 20.0%; p = 0.0021). Finally, in women with platinum-sensitive recurrence, we observed a shorter secondary PFI in the IDS compared to PDS group (p = 0.006). CONCLUSIONS: We documented a better behavior of recurrent disease in AOC patients with diffuse peritoneal carcinomatosis treated with complete PDS compared to women submitted to NACT followed by IDS with no residual tumor after surgery.

Ovarian cancer patients with localized relapse: clinical outcome and prognostic factors.

OBJECTIVE: We evaluated the clinical outcome and prognostic factors for post-relapse survival (PRS) in a large retrospective series of ovarian cancer patients with localized relapse. PATIENTS AND METHODS: The following radiological inclusion criteria were adopted: relapse in single anatomic site and ≤ 3 nodules. All cases were followed for at least 24 months after recurrent disease. RESULTS: Two hundred twenty ovarian cancer patients met the inclusion criteria. Serous histotype and G3 tumors were observed in 173 (78.6%) and 151 (77.4%) cases, respectively. All women received platinum-based first-line chemotherapy. Overall, the median follow-up was 46 (8-249) months, and platinum-resistant relapse was documented in 51 women (23.2%). Eighty-one patients (36.8%) recurred in the peritoneum (LPeR), 76 patients (34.5%) in the abdominal lymph nodes (LLNR), and 63 patients (28.7%) in parenchymal organs (LPaR); 142 patients (64.5%) recurred with a single nodule; and 78 patients (35.5%) recurred with 2-3 nodules. Secondary cytoreductive surgery (SCS) was attempted in 73 cases (33.2%), and complete debulking was achieved in all patients. On multivariate analysis, platinum-free interval (PFI, χ(2)=13.457, p value=0.001), complete SCS (median PRS, 69 months vs 25 months, p=0.001), anatomic site of relapse (median PRS, 41months in LPeRs, 63 months in LLNRs and 24 months in LPaRs, p=0.001), and number of nodules (median PRS, 58months in patients with one nodule, 24months in patients with 2-3 nodules, p=0.001) were identified as predictors of PRS. CONCLUSIONS: Beside the duration of PFI, the complete SCS, the anatomic site of relapse, and the number of nodules were independent prognostic factor for duration of PRS.
