MIRRORS: a prospective cohort study assessing the feasibility of robotic interval debulking surgery for advanced-stage ovarian cancer.

OBJECTIVE: To establish the feasibility and safety of robotic interval debulking surgery following the MIRRORS protocol (robot-assisted laparoscopic assessment prior to robotic or open surgery) in women with advanced-stage ovarian cancer. MIRRORS is the first of three planned trials: MIRRORS, MIRRORS-RCT (pilot), and MIRRORS-RCT. METHODS: The participants were patients with stage IIIc-IVb epithelial ovarian cancer undergoing neo-adjuvant chemotherapy, suitable for interval debulking surgery with a pelvic mass ≤8 cm. The intervention was robot-assisted laparoscopic assessment prior to robotic or open interval debulking surgery (MIRRORS protocol). The primary outcome was feasibility of recruitment, and the secondary outcomes were quality of life (EORTC QLQC30/OV28, HADS questionnaires), pain, surgical complications, complete cytoreduction rate (%), conversion to open surgery (%), and overall and progression-free survival at 1 year. RESULTS: Overall, 95.8% (23/24) of patients who were eligible were recruited. Median age was 68 years (range 53-83). All patients had high grade serous histology and were BRCA negative. In total, 56.5% were stage IV, 43.5% were stage III, 87.0% had a partial response, while 13.0% had stable disease by RECIST 1.1. Median peritoneal cancer index was 24 (range 6-38). Following MIRRORS protocol, 87.0% (20/23) underwent robotic interval debulking surgery, and 13.0% (3/23) had open surgery. All patients achieved R<1 (robotic R0=47.4%, open R0=0%). No patients had conversion to open. Median estimated blood loss was 50 mL for robotic (range 20-500 mL), 2026 mL for open (range 2000-2800 mL) (p=0.001). Median intensive care length of stay was 0 days for robotic (range 0-8) and 3 days (range 3-13) for MIRRORS Open (p=0.012). The median length of stay was 1.5 days for robotic (range 1-17), 6 days for open (range 5-41) (p=0.012). The time to chemotherapy was as follows 18.5 days for robotic (range 13-28), 25 days for open (range 22-28) (p=0.139). CONCLUSIONS: Robotic interval debulking surgery appears safe and feasible for experienced robotic surgeons in patients with a pelvic mass ≤8 cm. A randomized controlled trial (MIRRORS-RCT) will determine whether MIRRORS protocol has non-inferior survival (overall and progression-free) compared with open interval debulking surgery.

Enhanced Recovery after Uterine Corpus Cancer Surgery: A 10 Year Retrospective Cohort Study of Robotic Surgery in an NHS Cancer Centre.

Royal Surrey NHS Foundation Trust introduced robotic surgery for uterine corpus cancer in 2010 to support increased access to minimally invasive surgery, a central element of an enhanced recovery after surgery (ERAS) pathway. More than 1750 gynaecological oncology robotic procedures have now been performed at Royal Surrey NHS Foundation Trust. A retrospective cohort study was performed of patients undergoing surgery for uterine corpus cancer between the 1 January 2010 and the 31 December 2019 to evaluate its success. Data was extracted from the dedicated gynaecological oncology database and a detailed notes review performed. During this time; 952 patients received primary surgery for uterine corpus cancer; robotic: n = 734; open: n = 164; other minimally invasive surgery: n = 54. The introduction of the Da VinciTM robot to Royal Surrey NHS Foundation Trust was associated with an increase in the minimally invasive surgery rate. Prior to the introduction of robotic surgery in 2008 the minimally invasive surgery (MIS) rate was 33% for women with uterine corpus cancer undergoing full surgical staging. In 2019, 10 years after the start of the robotic surgery program 91.3% of women with uterine corpus cancer received robotic surgery. Overall the MIS rate increased from 33% in 2008 to 92.9% in 2019. Robotic surgery is associated with a low 30-day mortality (0.1%), low return to theatre (0.5%), a low use of blood transfusion and intensive care (1.8% & 7.2% respectively), low conversion to open surgery (0.5%) and a reduction in median length of stay from 6 days (in 2008) to 1 day, regardless of age/BMI. Robotic survival is consistent with published data. Introduction of the robotic program for the treatment of uterine cancer increased productivity and was associated with a highly predicable patient pathway of care, for high-risk patients, with reduced demands on health services. Future health care commissioning should further expand access to robotic surgery nationally for women with uterine corpus cancer.

World Gynecologic Oncology Day: the use of Twitter to raise awareness of gynecologic cancers.

BACKGROUND: Social media provides an opportunity for people to connect and form communities. This community architecture can help to disseminate health-related information in the form of an awareness campaign. The European Society of Gynaecological Oncology and the European Network of Gynaecological Cancer Advocacy Groups initiated a global campaign, World Gynecologic Oncology Day, on September 20, 2020. We studied and analyzed the impact and reach of this Twitter campaign. OBJECTIVE: This study aimed to assess the impact and reach of the 2020 World Gynecologic Oncology Day Twitter campaign. STUDY DESIGN: We analyzed gynecologic oncology-specific posts (tweets) between 12 am on September 17, 2020, to 11:59 pm on September 25, 2020 (Coordinated Universal Time), covering the days immediately before and after World Gynecological Oncology Day (September 20, 2020), using Tweepy. The European Network of Gynecological Cancer Advocacy Groups suggested hashtags (#GoForPurple, #WorldGODay, and #GoForCheckup) should be used for this social media campaign. We used these hashtags for our data (tweet) collection. RESULTS: A total of 382 Twitter accounts participated in this campaign and 662 tweets, including retweets, were reported. Of those, 22% of participants were healthcare professionals. A total of 164 unique hashtags were identified, and #WorldGODay was the most frequently used among the Twitter accounts. #VaginalCancer, #CervicalCancer, and #VulvarCancer were used in relation to the campaign. We identified 5 significant communities that contributed to raising awareness. CONCLUSION: Twitter campaigns should be designed around a single, short, easy-to-spell hashtag and coordinated with previously identified influential accounts using timed tweets. #WorldGOday hashtag was relevant, easy to spell, memorable, and the most effective hashtag used in this campaign.

COVID-19 and gynecological cancer: a review of the published guidelines.

On March 11, 2020 the COVID-19 outbreak was declared a 'pandemic' by the World Health Organization. COVID-19 is associated with higher surgical morbidity and mortality. An array of guidelines on the management of cancer during this pandemic have been published since the first reports of the outbreak. This narrative review brings all the relevant information from the guidelines together into one document, to support patient care. We present a detailed review of published guidelines, statements, comments from peer-reviewed journals, and nationally/internationally recognized professional bodies and societies' web pages (in English or with English translation available) between December 1, 2019 and May 27, 2020. Search terms included combinations of COVID, SARS-COV-2, guideline, gynecology, oncology, gynecological, cancer. Recommendations for surgical and oncological prioritization of gynecological cancers are discussed and summarized. The role of minimally invasive surgery, patient perspectives, medico-legal aspects, and clinical trials during the pandemic are also discussed. The consensus is that elective benign surgery should cease and cancer surgery, chemotherapy, and radiotherapy should continue based on prioritization. Patient and staff face-to-face interactions should be limited, and health resources used efficiently using prioritization strategies. This review and the guidelines on which it is based support the difficult decisions currently facing us in gynecological cancer. It is a balancing act: limited resources and a hostile environment pitted against the time-sensitive nature of cancer treatment. We can only hope to do our best for our patients with the resources available to us.

Growth-induced changes in the proteome of Helicobacter pylori.

Helicobacter pylori is a major human pathogen that is responsible for a number of gastrointestinal infections. We have used 2-DE to characterise protein synthesis in bacteria grown either on solid agar-based media or in each of two broth culture media (Brucella and brain heart infusion (BHI) broth). Significant differences were observed in the proteomes of bacteria grown either on agar-based or in broth media. Major changes in protein abundance were identified using principal component analysis (PCA), which delineated the profiles derived for the three key growth conditions (i.e. agar plates, Brucella and BHI broth). Proteins detected across the gel series were identified by peptide mass mapping and Edman sequencing. A number of proteins associated with protein synthesis in general as well as specific amino acid synthesis were depressed in broth-grown bacteria compared to plate-grown bacteria. A similar reduction was also observed in the abundance of proteins involved in detoxification. Two of the most abundant spots, identified as UreB and GroEL, in plate-grown bacteria showed a >140-fold drop in abundance in bacteria grown in Brucella broth compared to bacteria grown on agar plates. Two protein spots induced in bacteria grown in broth culture were both identified as glyceraldehyde 3-phosphate dehydrogenase based on their N-terminal amino acid sequences derived by Edman degradation. The underlying causes of the changes in the proteins abundance were not clear, but it was likely that a significant proportion of the changes were due to the alkaline pH of the broth culture media.
