OBJECTIVE:This study was performed to examine the safety of bowel resection and upper abdominal surgery in patients with advanced ovarian cancer performed by gynecologic oncologists after training in a monodisciplinary surgical team. METHODS:We implemented a monodisciplinary surgical team consisting of specialized gynecologic oncologist for advanced ovarian cancer. In the initial learning period in 65 patients with International Federation of Gynecology and Obstetrics (FIGO) III/IV, a gynecologic oncologist who had a certification as a general surgeon trained 2 other gynecologic oncologists in bowel resection and upper abdominal surgery for 4 years. After the initial learning period, the trained gynecologic oncologists performed surgeries without the certificated general surgeon in 195 patients with FIGO III/IV. The surgical outcomes and perioperative complications during the 2 periods were evaluated. RESULTS:The rates of achieving no gross disease after cytoreductive surgery were 80.0% in the initial learning period and 83.6% in the post-learning period (p=0.560). The incidence of anastomotic leakage after rectosigmoid resection, symptomatic pleural effusion or pneumothorax after right diaphragm resection, and pancreatic fistula after splenectomy with distal pancreatectomy in the 2 periods were 2 of 34 (6.0%), 1 of 33 (3.0%), and 3 of 15 (20.0%) patients in the initial learning period, and 12 of 147 (8.2%), 1 of 118 (0.8%), and 11 of 84 (13.1%) patients in the post-learning period, respectively. There were no significant differences between the 2 groups (p=0.270, p=0.440, p=0.520, respectively). CONCLUSION:Bowel resection and upper abdominal surgery can be performed safely by gynecologic oncologists.

METHODS::Altered aerobic glycolysis is an important feature of cancer cell energy metabolism, known as the Warburg effect. Cervical cancer is one of the most common causes of cancer death in females. However, the roles of aerobic glycolysis in the development of cervical cancer are still poorly defined. Here, we identified a transcription factor (TF), ETS-related gene (ERG), as a new regulator of cancer progression and the glycolysis process in cervical cancer. In this study, we found that ectopic expression of ERG enhanced the capacity of aerobic glycolysis and increased glucose uptake, lactate production, and ATP generation. ERG overexpression increased and ERG knockdown decreased the anchorage independent cell growth and cell invasion in cervical cancer cells. Mechanistically, we propose that ERG regulates the expression of hexokinase 2 (HK2) and phosphoglycerate kinase 1 (PGK1) in the glycolytic pathway by directly binding to their promoters. A gain-of-function study showed that the knockdown or overexpression of HK2 and PGK1 abolished the increased or decreased aerobic glycolysis and cervical cancer progression induced by stable ectopic expression or depletion of ERG, respectively. Taken together, our findings suggest that ERG plays a potential role in the progression of cervical cancer, and could serve as a novel biomarker and potential therapeutic target in cervical cancer.

METHODS:INTRODUCTION:Australia has recently implemented major changes in cervical cancer prevention policies including introduction of primary human papillomavirus (HPV) screening starting at age 25, and replacement of the quadrivalent HPV vaccine with the nonavalent vaccine in the national school-based program. We assessed the feasibility and utility of conducting HPV testing in residual clinical specimens submitted for routine Chlamydia trachomatis screening, as a means of tracking HPV vaccine program impact among young sexually active women. METHODS:De-identified residual specimens from women aged 16-24 years submitted for chlamydia testing were collected from three pathology laboratories in Victoria and New South Wales. Limited demographic information, and chlamydia test results were also collected. Patient identifiers were sent directly from the laboratories to the National HPV Vaccination Program Register, to obtain HPV vaccination histories. Samples underwent HPV genotyping using Seegene Anyplex II HPV 28 assay. RESULTS:Between April and July 2018, 362 residual samples were collected, the majority (60.2%) of which were cervical swabs. Demographic data and vaccination histories were received for 357 (98.6%) women (mean age 21.8, SD 2.0). Overall, 65.6% of women were fully vaccinated, 9.8% partially, and 24.7% unvaccinated. The majority (86.0%) resided in a major city, 35.9% were classified in the upper quintile of socioeconomic advantage and chlamydia positivity was 7.8%.The prevalence of quadrivalent vaccine-targeted types (HPV6/11/16/18) was 2.8% (1.5-5.1%) overall with no differences by vaccination status (p = 0.729). The prevalence of additional nonavalent vaccine-targeted types (HPV31/33/45/52/58) was 19.3% (15.6-23.8%). One or more oncogenic HPV types were detected in 46.8% (95% CI 41.6-52.0%) of women. CONCLUSIONS:HPV testing of residual chlamydia specimens provides a simple, feasible method for monitoring circulating genotypes. Applied on a larger scale this method can be utilised to obtain a timely assessment of nonavalent vaccine impact among young women not yet eligible for cervical screening.

METHODS::Human papillomavirus (HPV) type 58 is the third most commonly detected HPV type in cervical cancer among Eastern Asians. Our previous international epidemiological studies revealed that a HPV58E7 natural variant, T20I/G63S (designated as V1), was associated with a higher risk of cervical cancer. We recently showed that V1 possesses a greater ability to immortalise and transform primary cells, as well as degrading pRB more effectively than the prototype and other common variants. In this study, we performed a series of phenotypic and molecular assays using physiologically relevant in vitro and in vivo models to compare the oncogenicity of V1 with that of the prototype and other common natural variants. Through activation of AKT and K-Ras/ERK signalling pathways, V1 consistently showed greater oncogenicity compared with prototype and other variants, as demonstrated by increased cell proliferation, migration and invasion, as well as induction of larger tumours in athymic nude mice. This study complements our previous epidemiological and molecular observations pinpointing the higher oncogenicity of V1 compared with prototype and all other common variants. Since V1 is more commonly found in Eastern Asia, our report provides insight into the design of HPV-screening assays and selection of components for HPV vaccines in this region.IMPORTANCE Epidemiological studies have revealed that a wild type variant of HPV58 carrying an E7 variation, T20I/G63S (V1), is associated with a higher risk of cervical cancer. We previously reported that this increased oncogenicity could be the result of its greater ability to degrade pRB, thereby leading to an increased ability to grow in an anchorage-independent manner. In addition to this, this report further showed that this HPV variant induced activation of AKT and K-Ras/ERK signalling pathways, thereby, explaining its genuine oncogenicity in promoting cell proliferation, migration, invasion, and formation of tumours, all to a greater extent than prototype HPV58 and other common variants.
