RESUMO
OBJECTIVE: To compare the diagnostic power of CT scan to a combination of exploratory laparoscopy (EXL) and CT scan in patients with stage IIIC-IV Ovarian Cancer (OC) by anatomic areas. To investigate if adding EXL to CT can reduce unnecessary laparotomy. METHODS: In the period 2009-2017, 350 consecutive patients with FIGO Stage IIIC-IV OC underwent CT and EXL prior to Visceral-Peritoneal debulking (VPD) and were included in the study. Radiologist and surgeons filled an ad-hoc form to report CT scan and EXL of eleven key anatomic areas. The decision to proceed to EXL was based on the CT scan and the decision to proceed to laparotomy (LPT) on CT and EXL. Setting LPT findings as the gold standard, positive and negative predictive value (PPV/NPV), sensitivity, specificity, and accuracy of CT, EXL and CT + EXL were calculated. We broke down the diagnostic outcomes by anatomic areas and determined the rate of unnecessary laparotomy avoided with the findings of EXL. RESULTS: Median time for the EXL was 14 min (SD +/- 3). No complication related to EXL occurred. At EXL, 325 out of 350 patients (93%) proceeded to LPT and 25 patients (7.1%) did not because of exclusion criteria. In 307 patients out of 325 (94.4%) EXL was followed by VPD. Eighteen patients had exclusion criteria found at LPT and had no VPD. EXL reduced the rate of unnecessary/futile laparotomy from 12.2% to 5.1%. CT + EXL showed a significantly higher sensitivity for all anatomic areas except for the lymph nodes. Specificity was not significantly improved. PPV was significantly improved for small bowel, porta hepatis and stomach. NPV displayed a statistical improvement in all anatomic areas except lymph nodes, stomach, and liver. CONCLUSION: The combination CT + EXL has a higher diagnostic power than CT alone, particularly on diaphragm, small bowel serosa and mesentery. The rate of unnecessary laparotomy decreased by almost 60%.

OBJECTIVE: In this study we describe the technique of the En-bloc resection of the pelvis (EnBRP) in 10 standardised and reproducible steps, whereby all pelvic organs, except the bladder, are removed together with the peritoneum. In addition, we compare the surgical and survival outcomes of patients who underwent upfront vs. interval surgery. METHODS: Retrospective analysis of patients with FIGO Stage IIIC-IV ovarian cancer treated with Visceral Peritoneal Debulking (VPD) who had EnBRP. The study population was divided into Group 1 (up-front VPD) and group 2 (VPD after neo-adjuvant chemotherapy). The aim was to assess the incidence of EnBRP. We also assessed rate of complete resection (CR), procedure-specific and overall morbidity, disease free and overall survival. Results were compared between group 1 and 2. RESULTS: Overall 92 out of 200 patients (46%) needed an EnBRP during the VPD. Forty-eight patients were in Group 1 and 44 patients in Group 2. CR was achieved in all patients. No intra-operative procedure specific morbidity was recorded. Dehiscence of bowel anastomosis was the only procedure specific morbidity. Rate was 2%, with 1 episode recorded in each group. Both patients were managed and settled with formation of a bowel diversion. The overall morbidity rate was 33%, 35% in group 1 and 31% in group 2. The mortality rate was 1%. Median disease free survival was 20months, 25 in group 1 vs. 15 in group 2 (P=0.009). CONCLUSIONS: EnBRP is a safe and effective technique to tackle the pelvic disease of patients with advanced ovarian cancer. The reduced blood loss, the high rate of clear margins and CR of the disease are accompanied by a low rate of surgical morbidity. These features are particularly suitable for patients who are due to start or re-start chemotherapy. The standardization of the technique will make it more reproducible and easier to be taught. In addition, it will facilitate comparison of results and the inclusion of this technique in the portfolio of procedures as part of debulking surgery.

OBJECTIVE: To describe the technique and evaluate the feasibility, efficacy and morbidity of the Laparoscopic En-Bloc Resection of the Pelvis (L-EnBRP) during Visceral-Peritoneal Debulking (VPD) at time of interval surgery. METHODS: This report is part of a prospective non randomized study (service evaluation protocol) on the feasibility and safety of laparoscopy in patients with stage IIIC-IV ovarian cancer and gross residual disease following neoadjuvant chemotherapy. Primary endpoints of this part of the study were the feasibility (rate of patients in whom the surgery could be completed by laparoscopy), efficacy (rate of patients ended with a complete resection) and morbidity (number of patients that suffered complications specifically associated to the procedure) of L-EnBRP. The results were compared between patients in group 1 (L-EnBRP+L-VPD), group 2 (L-EnBRP+VPD) and group 3 (VPD). RESULTS: Eighteen patients were in group 1, 8 in group 2 and 32 in group 3. Feasibility of L-EnBRP was 45% (26 patients out of 58), efficacy was 100% of the pelvic disease (94.4% overall disease) and morbidity was 5.5%. Main cause for conversion to laparotomy was high tumor load on diaphragm and/or mesentery. All but one patient had a complete resection (CR) of the disease. Group 1 patients had significantly earlier hospital discharge, lower blood loss and reduced overall morbidity than group 2 and 3. CONCLUSION: L-EnBRP was feasible in almost half of the patients. In these patients a CR was achieved with a low morbidity rate. The latter was significantly decreased when compared to the patients who had a laparotomy.

OBJECTIVE: To compare the surgical and histological outcomes of diaphragmatic peritonectomy vs. full thickness resection with pleurectomy during Visceral-Peritoneal Debulking. METHODS: Service evaluation protocol (Trust number 3265). All patients with stage IIIC-IV ovarian cancer who had diaphragmatic surgery between April 2009 and November 2013 were included. Clinical notes and histology reports were reviewed. Additional histology sections were undertaken. Patients were divided in Groups 1 (peritonectomy) and 2 (pleurectomy). The outcomes of interest were: surgical (intra- and post-operative morbidity, pulmonary morbidity, mortality, rate of complete resection) and histological (rate of diaphragmatic peritoneum, muscle and pleural involvement, rate of microscopic diaphragmatic free margins). RESULTS: Sixty four patients had diaphragmatic peritonectomy (Group 1), 36 patients full thickness diaphragmatic resection with pleurectomy (Group 2). There was no significant difference in the rate of mortality (3% in both groups), overall intra- and post-operative morbidity (32.8% vs. 38.8%), pulmonary morbidity (9.3% vs. 19%, P=0.14). Histology showed tumor invasion in the diaphragmatic peritoneum (96%), muscle (28%) and pleura (19.4%). Microscopic free margins were seen in 86% vs. 92% in Groups 1 and 2. CONCLUSIONS: Our study demonstrated that, in patients with ovarian cancer, diaphragmatic involvement extends to the muscle in almost 30% and to the pleura in 20% of the patients. Overall and specific morbidity was not significantly different when comparing peritonectomy vs. pleurectomy.

OBJECTIVE: To report the surgical technique of ovarian cancer resection at the porta hepatis (PH) and hepato-celiac lymph nodes (HCL). To assess surgical and survival outcomes. Define the accuracy of an integrated diagnostic pathway. METHODS: Patients with FIGO stage IIIC-IV ovarian cancer that underwent Visceral-Peritoneal Debulking (VPD). Data of patients with disease at the PH/HCL during VPD were extracted from our database. The CT scan findings were compared with the exploratory laparoscopy. Accuracy of CT scan, intra- and post-operative morbidity, rate of complete resection (CR), disease free and overall survival are reported. RESULTS: Thirty one patients out of 216 (14.3%) had tumor at the PH and/or HCL. In 8 patients out of 31 (25.8%) it was only found with the aid of the exploratory laparoscopy. CR was achieved in 28 patients out of 31 (90.3%). Pathology confirmed disease in the PH/HCL specimens of all but one patient. Overall morbidity relating to the VPD was 29.2%. No complication was specifically related to the PH/HCL. Median disease free survival was 19months and median overall survival was 42months. CONCLUSION: PH/HCL surgery was required in 15% of patients with FIGO stage IIIC-IV. The surgery was feasible, safe and significantly contributed to CR. CT scan failed to identify the disease in 31% of the patients. CT and laparoscopy correctly identified all patients.

OBJECTIVE: To measure the efficacy and the safety of Visceral-Peritoneal Debulking (VPD) in patients with stage IIIC-IV ovarian cancer and to compare the outcomes before and after chemotherapy. METHODS: Between 2008 and 2013, 200 consecutive patients were offered VPD for stage IIIC/IV ovarian cancer. Exclusion criteria were: metastases in the lungs or 3 liver segments at CT review and/or disease on small bowel serosa or encasing the porta hepatis at explorative laparoscopy. The endpoints were efficacy (rate of complete resection, CR) and safety (morbidity and mortality). The results were compared between patients in group 1 (upfront surgery) and group 2 (during or after chemotherapy). RESULTS: Ninety-eight patients were in group 1 and 102 in group 2. Twenty out of 200 patients (10%) did not have VPD, 180 out of 200 patients (90%) had VPD and CR: 90.8% in group 1, 89.8% in group 2. The mortality (1%) and intra-operative complication rate (3.3%) were similar. Post-operative complications rate was 34.8% in group 1 vs. 30.7% in group 2 (P=0.669). The difference in grade III (15.7% vs. 5.5%, P=0.053) and grade IIIb complications (13.4% vs. 4.4%, P=0.062) approached statistical significance. All other outcomes were not significantly different in the 2 groups. CONCLUSION: VPD achieved CR in 90% of the patients. Neo-adjuvant chemotherapy did not increase the rate of CR and did not significantly decrease the morbidity or the complexity of the surgery.

PURPOSE OF REVIEW: To highlight the advances and the data published in the field of gynaecological oncology surgery in the last few years. The review includes not only newly introduced surgical techniques but also data that consolidate recent developments. RECENT FINDINGS: Ultimate data on the use of laparoscopy in the treatment of gynaecologic malignancies have proven similar survival outcomes to the traditional surgical route and confirmed the benefits in terms of faster recovery and lower morbidity. Thanks to a faster learning curve, the use of robotic surgery has contributed to the increase in the number of surgeons who moved away from open surgery. A few pioneers are expanding the indications of laparoscopy to exenterative surgery and treatment of ovarian cancer. SUMMARY: Laparoscopic surgery has become the gold standard treatment for patients with primary endometrial or cervical cancer. The advent of robotic surgery has reinforced the domain of endoscopic surgery.

In the UK, more than 3,200 new cases of cervical cancer are diagnosed each year. Early stage cervical cancer (IA2-IB1) treatment comprises central surgery mainly in the form of radical hysterectomy or fertility sparing surgery including trachelectomy as well as systematic pelvic lymphadenectomy to detect metastases and adjust treatment accordingly. Given the variation in determining the lymph node (LN) status, a major prognosticator, we reviewed the current UK practice of LN assessment in women undergoing surgery for early cervical cancer. A 7-question, web-based survey, screened by the BGCS committee, was circulated amongst BGCS members. The overall response rate was 51%. Only 12.5% of the respondents routinely performed frozen section examination (FSE); the main reasons for not doing FSE were the pressure on theatre time (54.5%) and the lack of available facilities (48.5%). When positive pelvic nodal disease was detected, in 21 out of 50 (42%) the planned radical hysterectomy (RH) was aborted. More than 70% of the respondents routinely performed RH without any prior resort to pelvic lymphadenectomy. Pretreatment surgical para-aortic LN assessment was performed by 20% of the respondents. The survey confirms the diversity of the UK practice patterns in the surgical treatment of early cervical cancer.

BACKGROUND: Pelvic irradiation is essential for improving survival in women with pelvic malignancies despite inducing permanent ovarian damage. Ovarian transposition can be performed in premenopausal women in an attempt to preserve ovarian function. As uncertainty occurs over the proportion of women who are likely to benefit from the procedure, we performed a systematic review and meta-analysis of the proportion of women with ovarian function preservation, symptomatic or asymptomatic ovarian cysts and metastatic ovarian malignancy following ovarian transposition. METHODS: Medline, Embase and The Cochrane Library databases were systematically searched for articles published from January 1980 to December 2013. We computed the summary proportions for ovarian function preservation, ovarian cyst formation and metastatic ovarian disease following ovarian transposition by random effects meta-analysis with meta-regression to explore for heterogeneity by type of radiotherapy. RESULTS: Twenty four articles reporting on 892 women undergoing ovarian transposition were included. In the surgery alone group, the proportion of women with preserved ovarian function was 90% (95% CI 92-99), 87% (95% CI 79-97) of women did not develop ovarian cysts and 100% (95% CI 90-111) did not suffer metastases to the transposed ovaries. In the brachytherapy (BR)± surgery group, the proportion of women with preserved ovarian function was 94% (95% CI 79-111), 84% (95% CI 70-101) of women did not develop ovarian cysts and 100% (95% CI 85-118) did not suffer metastases to the transposed ovaries. In the external beam radiotherapy (EBRT) +surgery ± BR group, the proportion of women with preserved ovarian function was 65% (95% CI 56-74), 95% (95% CI 85-106) of women did not develop ovarian cysts and 100% (95% CI 90-112) did not suffer metastases to the transposed ovaries. Subgroup meta-analysis revealed transposition to the subcutaneous tissue being associated with higher ovarian cyst formation rate compared to the "traditional" transposition. CONCLUSION: Ovarian transposition is associated with significant preservation of ovarian function and negligible risk for metastases to the transposed ovaries despite common incidence of ovarian cysts.
