Fluorescence guided surgery to improve peritoneal cytoreduction in epithelial ovarian cancer: A systematic review of available data.

During surgery for advanced epithelial ovarian cancer (EOC), the most important prognostic factor is the absence of residual tumor. Invisible microscopic peritoneal metastasis (mPM) are not removed during surgery and can be responsible of peritoneal recurrences. The aim of this current systematic review is to assess the role of fluorescence in evaluating mPM in EOC. We performed a systematic review using bibliographic citations from PubMed, Clinical Trials.gov, Embase, Cochrane Library, and Web of Science databases. MeSH terms for fluorescence, EOC and peritoneal carcinomatosis were combined and not restricted to the English language. The final search was performed on September 1rst, 2021. The primary outcome was to determine the diagnostic accuracy of fluorescence. We also reviewed the different techniques used. Eighty-seven studies were identified. Of these, 10 were included for analysis. The sensitivity and specificity of fluorescence ranged between 66.7-100% and 54.2-100%, respectively. Most importantly, the negative predictive value (NPV) ranged from 90 to 100% Due to the heterogeneity of the studies, no consensus was reached concerning the optimal use of fluorescence in terms of type of dye, type and timing of injection and imager to use. No adverse event was reported. Fluorescence can safely be used in EOC to evaluate mPM with a high NPV. However, a randomized controlled trial is needed to homogenize current practice.

COVID-19 free oncologic surgical hub: The experience of reallocation of a gynecologic oncology unit during pandemic outbreak.

INTRODUCTION: During the SARS-CoV-2 pandemic, the majority of healthcare resources of the affected Italian regions were allocated to COVID-19 patients. Due to lack of resources and high risk of death, most cancer patients have been shifted to non-surgical treatments. The following reports our experience of a Gynaecologic Oncology Unit's reallocation of resources in a COVID-19 free surgical oncologic hub in order to guarantee standard quality of surgical activities. MATERIALS AND METHODS: This is a prospective observational study performed in the Gynaecologic Oncology Unit, on the outcomes of the reallocation of surgical activities outside the University Hospital of Bologna, Italy, during the Italian lockdown period. Here, we described our COVID-19 free surgical oncologic pathway, in terms of lifestyle restrictions, COVID-19 screening measures, and patient clinical, surgical and follow up outcomes. RESULTS: During the lockdown period (March 9th - May 4th, 2020), 83 patients were scheduled for oncological surgery, 51 patients underwent surgery. Compared to pre-COVID period, we performed the same activities: number of cases scheduled for surgery, type of surgery and surgical and oncological results. No cases of COVID-19 infection were recorded in operated patients and in medical staff. Patients were compliant and well accepted the lifestyle restrictions and reorganization of the care. CONCLUSIONSONCLUSIONS: Our experience showed that the prioritization of oncological surgical care and the allocation of resources during a pandemic in COVID-19 free surgical hubs is an appropriate choice to guarantee oncological protocols.

Results of a Phase I-II Study on Laser Therapy for Vaginal Side Effects after Radiotherapy for Cancer of Uterine Cervix or Endometrium.

Women who have previously received radiotherapy (RT) for gynecologic cancer often suffer from vaginal fibrosis and stenosis. The success of "non-ablative" laser therapy for postmenopausal vaginal atrophy has led to the idea of testing the laser in patients submitted to RT. In this prospective observational study, we selected patients who underwent pelvic RT followed by vaginal laser treatment. We scheduled three treatment sessions (at T0-T1-T2) and three controls (at T1-T2-T3) one month apart. The follow-up (at T4) was carried out six months after the last treatment. Vaginal Health Index (VHI) and vaginal length were evaluated. Sexual function was assessed through Female Sexual Function Index (FSFI). Overall, 43 patients with severe vaginal shortening, atrophy and stenosis was enrolled and treated with intravaginal non-ablative CO2 laser. We observed a progressive increase in vaginal length of 9% (p = 0.03) at T2 and 28% (p < 0.0001) at T3; effects were maintained at T4 (p < 0.0001). After the first application VHI showed a significant improvement of 57% at T3 (p < 0.0001). The results were maintained at T4 (p < 0.0001). No changes were found in FSFI. All procedures were well tolerated. In conclusion, laser therapy improved vaginal length and VHI in women undergoing pelvic RT; prospective studies are needed.
