Neuroendocrine tumors (NETs) are rare, representing 0.5% of all newly diagnosed malignancies. Rectal and anal canal (AC) NETs account for less than 1% of all rectal and AC cancers. Review our institutional experience on NET of the rectum and AC, with emphasis on demographic, histological and treatment features and oncologic outcomes. The study group was identified from the Portuguese Regional South Oncological Registry. From 2000 to 2014, 22 patients with rectal or AC NETs were treated at our institution. Medical records were retrospectively reviewed...

Background: There is limited knowledge on ileal pouch anal anastomosis (IPAA) function when performed on patients older than age 50 years. The aim of this study was to determine if surgery on those older than age 50 years impacts short-term complications or long-term function. Methods: A retrospective review of all patients undergoing IPAA for chronic ulcerative colitis at a single tertiary referral center between 2002 and 2013 was conducted. Short-term postoperative complications and long-term function and quality of life were analyzed according to age at pouch formation (age >50 vs age ≤50 years)...

Anastomotic leakage is the most common major complication after mid-low rectal cancer surgery. Due to lack of knowledge regarding the virtual mechanisms of anastomotic leakage, not much can be done to prevent its development. The aim of the present review was to discuss the prevention, early diagnosis, and treatment of anastomotic leakage after rectal cancer surgery. For patients with risk factors, such as anastomotic site within 4 cm from anus, obese men, lack of blood supply of the anastomotic site, neoadjuvant chemo radiotherapy, or patients with severe co-morbidity, aggressive preventive strategy should be adopted...

The incidence of anal cancer is increased in HIV-infected patients compared to the general population. Risk factors associated with the anal cancer precursor, high-grade squamous intraepithelial lesion (HSIL), have not been extensively studied in an urban black population with late stage HIV disease. We performed a retrospective chart review of HIV infected men at the Grady Ponce de Leon Center HIV Clinic in Atlanta, Georgia referred for high resolution anoscopy (HRA), a procedure where anal tissue is examined under magnification and abnormal areas are biopsied...

Background: Transrectal ultrasound (TRUS) is a cost-effective test for preoperative assessment of rectal cancer. However, whether the accuracy of TRUS staging is correlated with tumor location remains obscured. This study is designed to explore their relationship and confirm an optimal application of TRUS in rectal cancer restaging. Methods: From 2005 to 2011, rectal cancer patients with TRUS data were retrospectively reviewed. Patients were divided into five groups according to tumor-involved rectal segment (SEG) above the anal verge: SEG I 1-3cm, II 3-6cm, III 6-9cm, IV 9-12cm, and V 12-16cm...

AIM: Trans-anal total mesorectal excision (taTME) is a novel approach for resection of the rectum. Use of a standard insufflator to create pneumorectum, however, results in bellowing - large heaving motions from insufflation of air that can frustrate surgery. We report the successful application of our technique, stable pneumorectum using an inline glove (SPRING), for the performance of trans-anal rectal excision in a series of 17 patients using a standard laparoscopic insufflator. METHODOLOGY: A retrospective review of 17 patients using the SPRING technique was performed between October 2015 and October 2016...

Advances in research techniques have made it possible to map the microbial communities in the gastrointestinal (GI) tract, where the majority of bacteria in the human body reside. Disturbances in these communities are referred to as dysbiosis and have been associated with GI cancers. Although dysbiosis is observed in several GI malignancies, the specific role of these changes has not been understood to the extent of Helicobacter pylori (HP) in gastric cancer (GC). This review will address the bacterial communities along the GI tract, from the oral cavity to the anal canal, particularly focusing on bacterial dysbiosis and carcinogenesis...

AIM: Six phase III randomised trials have determined the effectiveness of chemoradiotherapy as primary treatment for anal squamous cell carcinoma (ASCC), but outcomes reported in these trials varied widely, hindering evidence synthesis. To improve reporting in all future trials, we aim to develop a core set of outcomes (COS). As the first stage of COS development, we undertook a systematic review to summarise the outcomes reported in studies evaluating chemoradiotherapy for ASCC. METHOD: Systematic literature searches identified studies evaluating radiotherapy or chemoradiotherapy for ASCC...

Human papillomavirus (hpv) infection is the cause of anal squamous cell cancer (ascc) in 80% of cases. Available research has also shown high prevalence of anal hpv infection among men who have sex with men (msm). However, hpv vaccination is low among msm in Canada. In light of this information, we conducted a scoping review with the aim of exploring (1) the knowledge of hpv and anal cancer among hiv-positive msm and (2) the acceptability of hpv and anal cancer self-sampling in this population. In conducting the review, we searched five electronic databases for peer-reviewed articles and abstracts published in English, between 2007 and 2017...

The aim of this paper is to describe the efficacy of Human Papilloma Virus (HPV) vaccines for preventing oral cancer. A systematic review of the literature was conducted to describe the state of the art about HPV vaccines for preventing oral cancer. The aspects of prevention and control of infection by administering vaccines and the diffusion of sexual education campaigns are discussed also. In recent years there has been a growing interest in HPV in dentistry, suggesting a role of such a family of viruses in the development of oral cancers as well as of the uterine cervix...
