Approximately 10-20% of inflammatory bowel disease (IBD) cases are diagnosed after 60 years of age. Due to the high prevalence of conditions mimicking IBD at older age - including bowel disease associated with non-steroidal anti-inflammatory drugs, diverticulitis, and microscopic colitis - differential diagnosis of IBD among older adults is frequently delayed. Late-onset IBD is characterized by a predominance of colonic disease and an overall milder disease course; disease progression and new intestinal manifestations are rare...

The incidence of anal cancer is increasing. The primary treatment consists of radiotherapy concomitant with chemotherapy. Short- and long-term side effects are common, and supportive care during treatment and rehabilitation after treatment is necessary. Locoregional recurrence is treated with an abdominoperineal resection with sigmoideostomia and/or lymph node exairesis. Staging and treatment is done centralized. The prognosis has improved over the latest 10-20 years with a long-term overall survival of > 70% after primary therapy and approximately 50% after surgical treatment for recurrence...

A 48-year-old man presented as an emergency with a 3-week history of rectal bleeding. Examination of his rectum revealed a circumferential tumour, 2 cm from the anal verge. An MRI scan reported a locally infiltrative mid-lower rectal tumour staged as T3d/T4 N2 MX. A colonoscopy revealed appearances of severe proctitis and biopsies did not show any evidence of dysplasia or malignancy. The patient was discussed at the regional colorectal cancer multidisciplinary team meeting with a management plan for neoadjuvant chemoradiotherapy following repeat biopsies, which were again negative for malignancy...

BACKGROUND: Although outcomes for patients with squamous cell carcinoma of the anus (SCCA) have improved, the gains in benefit may not be shared uniformly among patients of disparate socioeconomic status. In the current study, the authors investigated whether area-based median household income (MHI) is predictive of survival among patients with SCCA. METHODS: Patients diagnosed with SCCA from 2004 through 2013 in the Surveillance, Epidemiology, and End Results registry were included...

The efficacy of immunotherapy varies widely among different gastrointestinal cancers. Response to immune checkpoint inhibitors is shown to correlate with tumor mutation load (TML), mismatch repair deficiency (dMMR) status, and programmed cell death-ligand 1 (PD-L1) expression. Herein, we quantify TML, dMMR, and PD-L1 expression and determine their interrelationship in gastrointestinal cancers. Here, a total of 4125 tumors from 14 different gastrointestinal cancer sites were studied using validated assays. Next-generation sequencing (NGS) was performed on genomic DNA isolated from formalin-fixed paraffin-embedded (FFPE) tumor specimens using the NextSeq platform...

BACKGROUND: Intensity-modulated radiation therapy (IMRT) has been used to limit treatment-related toxicity for patients with anal squamous cell carcinoma (SCC). The treatment outcomes and HPV characteristics for a cohort of patients receiving definitive concurrent chemotherapy and IMRT are reported. MATERIALS AND METHODS: 52 patients with anal SCC were treated with IMRT and concurrent chemotherapy. Radiation was delivered sequentially to the pelvis and inguinal lymph nodes (45 Gy) and anal tumor (median dose, 54 Gy)...

PURPOSE: To evaluate inter-fraction tumor localization errors (TE) in the RapidArc® treatment of pelvic cancers based on CBCT. Appropriate CTV-to PTV margins in a non-IGRT scenario have been proposed. METHODS: Data of 928 patients with prostate, gynecological, and rectum/anal canal cancers were retrospectively analyzed to determine systematic and random localization errors. Two protocols were used: daily online IGRT (d-IGRT) and weekly IGRT. The latter consisted in acquiring a CBCT for the first 3 fractions and subsequently once a week...

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...

BACKGROUND: Despite advances in the treatment of rectal adenocarcinoma, the management of locally advanced disease remains a challenge. The standard of care for patients with stages II and III rectal cancer includes neoadjuvant chemoradiation followed by total mesorectal excision and postoperative chemotherapy. Much effort has been dedicated to the identification of predictive factors associated with pathologic complete response (pCR). The aim of our study was to examine our institutional experience and determine whether any association exists between anatomic tumor location and the rate of pCR...

OBJECTIVE: Human papillomavirus (HPV) is the most common sexually transmitted agent in the world. HPV6b is a low-risk type of HPVs that causes benign verrucous hyperplastic lesions of the skin and anal genital mucosa. Previous research has indicated that HPV genotype 6 is sometimes associated with high-grade lesions and anal cancer. The pathogenesis of low-risk HPV infection and its relationship to high-risk HPV is not clear at present. The E7 protein, which is encoded by HPV early -expressing genes, plays an important role in HPV infection...

Human papillomavirus (HPV) DNA and p16 expression have been identified to be related to the progression of anal squamous cell carcinoma (ASCC). However, the prognostic relevance of combined detection, particularly HPV-/p16+ and HPV+/p16- signatures, is unknown. A meta-analysis of epidemiologic studies was therefore conducted to address this issue. Data were collected from studies comparing overall survival (OS) and disease-free survival (DFS) / disease-specific survival (DSS) / relapse-free survival (RFS) / progression-free survival (PFS) in ASCC patients with HPV and p16 status...

The prevalence of Human Papillomavirus (HPV) in men who have sex with men (MSM) is high, reaching 85-93% prevalence in HIV-positive men. High-risk HPV are strongly associated with development of high degrees of anal intraepithelial neoplasia (AIN) which, later on, can develop in anal squamous carcinoma. The growing incidence of anal cancer during last years is particularly important in MSM and HIV-positive patients, in which the coexistence of multiple serotypes of HPV reduces the probability of eliminating the AIN...

The case was for a male at the age of 80. We performed laparoscopic left hemicolectomy and D3 lymph node dissection for descending colon cancer. He had a good postoperative prognosis and was discharged on the 14th day after the operation. Later, he was receiving the treatment on an outpatient basis without postoperative adjuvant chemotherapy during the followup period. He visited the hospital for sudden abdominal pain and melena as chief complaint approximately 4 months after the operation. We found prominent edematous wall thickening and increased surrounding fat concentration in the anal side of colon from the anastomosis site with plain abdominal CT scan...

Human papillomavirus (HPV) vaccination and anal cancer screening are valuable, yet underutilized, tools in prevention of HPV-related cancers among sexual and gender minority (SGM) populations. The aim of this study was to characterize primary care providers' (PCPs) practices and perceptions pertaining to HPV vaccination and anal cancer screening. A survey assessing self-reported practice characteristics related to HPV vaccination and anal cancer screening, as well as perceived barriers to vaccination and anal cancer screening at the patient-, provider-, and system-level was distributed to PCPs at a Federally-Qualified Health Center that specializes in care for SGM populations in the greater Boston area...

BACKGROUND: Evidence suggests that natural antibodies developed after HPV16 infection may protect some women but not men against subsequent HPV16 re-acquisition. Less is known whether antibodies developed following HPV16 infection are protective among men-who-have-sex-with-men (MSM). METHODS: 475 MSM from the Human Papillomavirus in Men (HIM) study were tested for serum antibodies to HPV16 L1 using enzyme-linked immunosorbent assays, and for anal and genital HPV16 DNA using PCR consensus primer system (PGMY 09/11)...
