The extent of peritoneal metastases (PM) largely determines the possibility of complete or optimal cytoreductive surgery in advanced ovarian cancer. An objective scoring system to quantify the extent of PM can help clinicians to decide whether or not to embark on CRS. Therefore several scoring systems have been developed by different research teams and this review summarizes their performance in predicting a complete or optimal cytoreduction in patients with advanced ovarian cancer. A systematic search in the MEDLINE database revealed 19 articles that described a total of five main scoring systems to predict the completeness of CRS in patients with FIGO stage III-IV ovarian cancer based on the surgical exploration of the abdominal cavity; PCI, PIV, Eisenkop, Espada, and Kasper. The Peritoneal Cancer Index (PCI) and the Predictive Index Value (PIV) were mentioned most frequently and showed AUCs of 0.69-0.92 and 0.66-0.98, respectively. Due to the use of different cut-offs sensitivities and specificities greatly varied. Therefore with the current data, no scoring system could be identified as best. An objective measure of the extent of disease can be of great clinical use for identifying ovarian cancer patients for which a complete (or optimal) CRS is achievable, however due to local differences in treatment strategies and surgical policy a widely adopted objective scoring system with a standard cut-off value is not feasible. Nevertheless, objective scoring systems can play an important role to guide treatment decisions., Competing Interests: Declaration of competing interest The authors declare the following financial interests/personal relationships which may be considered as potential competing interests: Dr. Sonke reports institutional research support outside the submitted work, from AstraZeneca, Merck, Novartis, and Roche, during the conduct of the study.

Introduction: The addition of hyperthermic intraperitoneal chemotherapy (HIPEC) to interval cytoreductive surgery (CRS) improves recurrence-free (RFS) and overall survival (OS) in patients with FIGO stage III ovarian cancer. We evaluated the effect of HIPEC on patient's health-related quality of life (HRQoL) in the OVHIPEC trial., Materials and Methods: OVHIPEC was a multicentre, open-label, randomized phase III trial for patients with stage III ovarian cancer. Patients were randomly assigned (1:1) to receive interval CRS with or without HIPEC with cisplatin. HRQoL was assessed using the EORTC QLQ-C30, and the ovarian (QLQ-OV28) and colorectal cancer (QLQ-CR38) modules. HRQoL questionnaires were administered at baseline, after surgery, after end of treatment, and every three months thereafter. HRQoL was a secondary endpoint, with the prespecified focus on the QLQ-C30 summary score and symptom scores on fatigue, neuropathy and gastro-intestinal symptoms. HRQoL was analysed using linear and non-linear mixed effect models., Results: In total, 245 patients were randomized. One-hundred-ninety-seven patients (80%) completed at least one questionnaire. No significant difference over time in the QLQ-C30 summary scores was observed between the study arms (p-values for linear and non-linear growth: p > 0.133). The pattern over time for fatigue, neuropathy and gastro-intestinal symptoms did not significantly differ between treatment arms., Conclusion: The addition of HIPEC to interval CRS does not negatively impact HRQoL in patients with stage III ovarian cancer who are treated with interval CRS due to the extent of disease. These HRQoL results, together with the improvement in RFS and OS, support the viability of HIPEC as an important treatment option in this patient population.

Introduction: The care for patients with epithelial ovarian cancer(EOC) is organised in eight different geographical regions in the Netherlands. This situation allows us to study differences in practice patterns and outcomes between geographical regions for patients with FIGO stage IIIC and IV., Methods: We identified all EOC patients who were diagnosed with FIGO stage IIIC or IV between 01.01.2008 and 31.12.2015 from the Netherlands Cancer Registry. Descriptive statistics were used to summarize treatment and treatment sequence(primary cytoreductive surgery(PCS) or neoadjuvant chemotherapy and interval cytoreductive surgery(NACT-ICS)). Moreover, outcome of surgery was compared between geographical regions. Multilevel logistic regression was used to assess whether existing variation is explained by geographical region and case-mix factors., Results: Overall, 6,741 patients were diagnosed with FIGO IIIC or IV disease. There were no differences in the percentage of patients that received any form of treatment between the geographical regions(range 80-86%, P = 0.162). In patients that received cytoreductive surgery and chemotherapy, a significant variation between the geographical regions was observed in the use of PCS and NACT-ICS(PCS: 24-48%, P < 0.001). The percentage of complete cytoreductive surgeries after PCS ranged from 10 to 59%(P < 0.001) and after NACT-ICS from 37 to 70%(P < 0.001). Moreover, geographical region was independently associated with the outcome of surgery, also when adjusted for treatment sequence(P < 0.001)., Conclusion: We observed a significant variation in treatment approach for advanced EOC between geographical regions in the Netherlands. Furthermore, the probability to achieve no residual disease differed significantly between regions, regardless of treatment sequence. This may suggest that surgical outcomes can be improved across geographical regions., (Copyright © 2019 Elsevier Ltd, BASO ~ The Association for Cancer Surgery, and the European Society of Surgical Oncology.

Background: An important benefit of neoadjuvant chemotherapy, as compared to adjuvant chemotherapy, in breast cancer patients is down staging of the primary tumour, which allows for more breast-conserving surgery. When a tumour becomes non-palpable after this down staging, precise localisation of the original tumour bed is crucial to be able to perform breast-conserving surgery. Radioguided Occult Lesion Localisation with (99m)Technetium (ROLL-(99m)Tc) is commonly used to perform breast-conserving surgery in patients with non-palpable breast tumours. We modified this technique to use it in the neoadjuvant setting. The present analysis was performed to assess its feasibility and analyse the number of patients in which a mastectomy was correctly withheld using this technique., Methods: A retrospective analysis was performed for all patients who were treated with neoadjuvant chemotherapy between 2007 and 2010 in our institute and underwent breast-conserving surgery with the ROLL-(99m)Tc technique afterwards. The status of the margins and the weight of the resected specimen were assessed., Results: The median weight of the resected specimen in these 83 patients was 53 g (range: 11-204 g). Eleven of the 58 patients with residual disease revealed positive margins at pathological examination. However, in only 5 of those 11 patients a secondary mastectomy was indicated. This means that in 94% of all included patients a mastectomy was correctly withheld., Conclusion: The ROLL-(99m)Tc technique is a feasible technique that can be used to perform breast-conserving surgery after neoadjuvant chemotherapy in a carefully selected group of patients., (Copyright © 2012 Elsevier Ltd.

Background: Neoadjuvant chemotherapy is gaining acceptance as an option for breast cancer treatment, particularly in young women. These women may seek immediate breast reconstruction after mastectomy even though it is not known whether such preoperative chemotherapy may be detrimental to post-reconstruction wound healing. Therefore, we set out to assess the influence of neoadjuvant chemotherapy for invasive breast cancer on the short-term complications after skin sparing mastectomy and immediate prosthetic reconstruction., Methodology: The short-term surgical outcome of 48 immediate breast reconstructions in 37 women treated with neoadjuvant chemotherapy from 2006 through 2009 was prospectively compared to that of 215 immediate reconstructions in 176 women who were operated in the same period without neoadjuvant chemotherapy., Results: The overall rate of short-term postoperative complications was significantly less among neoadjuvantly treated women (15% vs. 29%; p = 0.042) but this did not result in a reduction of loss of prostheses (8% vs. 11%; p = 0.566)., Conclusion: Because neoadjuvant chemotherapy is not associated with an increase in short-term complications after skin sparing mastectomy and immediate prosthetic reconstruction in patients with invasive breast cancer, such combined surgical therapy may be offered as treatment option for this particular group of patients also., (Copyright © 2011 Elsevier Ltd.
