BACKGROUND: Although the benefit of chemoradiation over radiation therapy alone has been shown in randomized trials for stage II to III squamous cell of the anus, this benefit is not clear for patients with stage I cancer. Nevertheless, most societal recommendations endorse chemoradiation for patients with stage I squamous cell carcinoma of the anus despite the lack of proven benefit and potential increase in toxicity. OBJECTIVE: The purpose of this study was to determine whether outcomes are improved with the addition of chemotherapy versus radiation alone for stage I squamous cell carcinoma of the anus...

BACKGROUND: Management of squamous cell carcinoma of the anus (SCCA) is becoming more relevant, as its incidence increases. The purpose of this study was to investigate possible differences in patient population and care delivery for SCCA between academic and community cancer programs in the United States. METHODS: A review of available data from the American College of Surgeons Committee on Cancer National Cancer DataBase focused on gender, age, race, type of health insurance, comorbidity score, distance traveled for care, stage at diagnosis, and therapy utilization (surgery, chemotherapy, and radiation therapy) as first course of treatment (FCT)...

Purpose: Patterns of failure and long term outcomes were prospectively evaluated following tumor factors-stratified radiation dose for anal/perianal cancer. Methods: Between 2008-2013, patients with anal/perianal squamous cell carcinoma were accrued to an institutional REB-approved prospective study. All patients were treated with image-guided intensity-modulated radiation therapy (IG-IMRT). Radiation dose selection (27-36 Gy for elective target, and 45-63 Gy for gross target) was based on tumor clinico-pathologic features...

BACKGROUND: High resolution anoscopy (HRA) examination is regarded as the best method for the management of anal high grade squamous intraepithelial lesions to prevent anal squamous carcinoma. However, little is known about the acceptability of this procedure. This analysis looks at patient experience of HRA examination and ablative treatment under local anaesthetic. METHODS: Patients took part in anonymised feedback of their experience immediately after their HRA examinations and/or treatments...

Anal intraepithelial neoplasia (AIN) is a precursor of anal carcinoma. Conventional therapy is based on topical and local ablative approaches. However, the recurrence rates are very high, leading to repetitive treatment sessions and need for long-term surveillance. Endoscopic submucosal dissection (ESD) is an established treatment for malignant early neoplasias of the gastrointestinal tract, especially in the esophagus, stomach, and colorectum. Japanese centers have reported few cases of ESD for early anal carcinoma...

BACKGROUND: Gastrointestinal metastasis from primary breast carcinoma is uncommon, anorectal involvement is extremely rare. CASE PRESENTATION: We present the case of a 65-year old woman who underwent treatment for an infiltrative lobular carcinoma of the left breast with bone metastases and who developed metastasis of the rectum and anal canal 4 years later. CONCLUSIONS: A patient with a history of breast cancer, especially lobular carcinoma, presenting with anorectal symptoms, should raise the suspicion of metastatic disease...

BACKGROUND: Concurrent chemo-radiation (CT-RT) is a standard therapy for squamous cell carcinoma of anal canal. Different clinical and biological factors may potentially affect outcome. We investigated the prognostic role of baseline hemoglobin (Hb) in a cohort of anal cancer patients submitted to CT-RT with 5-fluorouracil and mitomycin C. METHODS: Up to 161 patients with clinical stage T1-T4/N0-N3/M0 were treated. Response was assessed at 6 weeks and thereafter at 3, 6 and 12 months...

BACKGROUND: Human papillomavirus (HPV) can cause cervical, other genital, anal, head, and neck cancers. The incidence of oropharyngeal squamous cell carcinoma (OSCC), the head and neck cancer most commonly caused by HPV infection, is increasing. The prevalence of oral HPV infections is considerably lower than that of genital HPV infections; however, infection of both sites is strongly associated with sexual behavior. Although the natural histories of cervical and oral HPV infections do not markedly differ, the virus seems to rarely infect oral and genital sites simultaneously...

BACKGROUND: Failure of chemoradiotherapy (CRT) for anal squamous cell carcinoma (SCC) results in persistent or recurrent anal SCC. Treatment with salvage abdominoperineal resection (APR) can potentially achieve cure. The aims of this study are to analyze oncological and surgical outcomes of our 30-year experience with salvage APR for anal SCC after failed CRT and identify prognostic factors for overall survival (OS). METHODS: All consecutive patients who underwent salvage APR between 1990 and 2016 for histologically confirmed persistent or recurrent anal SCC after failed CRT were retrospectively analyzed...

OBJECTIVE: The purpose of this article is to review tumor staging systems for gastrointestinal tumors including pancreatic adenocarcinoma, hepatocellular carcinoma, cholangiocarcinoma, gastric adenocarcinoma, small bowel adenocarcinoma, rectal carcinoma, and anal carcinoma and identify the key imaging findings ("tipping points"), which change patient management based on changes in tumor staging. CONCLUSION: For all malignant gastrointestinal tumors, there are key imaging findings ("tipping points") including tumor size, tumor extension, lymphadenopathy, vascular invasion, and distant metastasis that dictate patient management and prognosis, based on changes in tumor stage...

A 69-year-old man was admitted for the growing anal tumor and referred to our hospital. The tumor was about 40mm in size, and by biopsy, he was diagnosed the adenocarcinoma. Based on this diagnosis, abdominoperinealresection and edge resection were performed. Histopathologicalfindings showed mucinous carcinoma originating from analgl and with pagetoid spread. Postoperative chemotherapy was not performed, but 1 year 6 months after the surgery, inguinall ymph node recurrence was found, and lymph node dissection was performed...

Chemotherapy concurrent with radiotherapy has been widely used in clinical practice because the additional benefit on radiotherapy alone had shown. Head and neck cancer: CDDP concurrent with radiotherapy has been a standard treatment for 15years both in definitive setting and postoperative setting. Esophageal cancer: 5-FU/CDDP is the best partner for radiotherapy and appropriate radiation dose has been discussed. Anal cancer: Radical concurrent chemoradiotherapy with 5-FU and mitomycin C(MMC)remains the standard of care for squamous cell carcinoma of the anus...

PURPOSE: Chemoradiation allows for organ preservation in patients with anal cancer, but patients with large tumors (> 5 cm) have elevated rates of locoregional recurrence. With conformal radiation techniques, there is interest in dose escalation to decrease local recurrence in patients with large tumor size. METHODS/PATIENTS: The National Cancer Database (NCDB) was used to identify patients with anal cancer from 2004 to 2013 with tumors > 5 cm. Adult patients who received definitive chemoradiation were included...

Primary squamous cell carcinoma of the rectum is extremely rare. Squamous cell carcinoma of the anorectum is a known entity evaluation and treatment protocols have been well defined. The occurrence of squamous cell carcinoma of rectosigmoid in concurrence with squamous cell carcinoma of the anal canal is extremely rare and the first case to be reported in the literature. A 48-year-old male patient presented with difficulty in passing stools. The clinical examination, colonoscopy, and the histopathology revealed synchronous proctosigmoid and the anorectal neoplasm...

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...

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...

Anal squamous cell carcinoma (ASCC), either with human papillomavirus (HPV) (+) or (-), is a neoplastic disease with frequent recurrence and metastasis. To characterize ASCC genomes, we attempted to disclose novel alterations of ASCC genomes as well as other genetic features including mutation signatures. We performed whole-exome sequencing and copy number alteration (CNA) profiling for 8 ASCC samples from 6 patients (2 cases with primary and recurrent/metastatic tumors). We found known ASCC mutations (TP53, CDKN2A and PIK3CA) and CNAs (gains on 3q and 19q and losses on 11q and 13q)...

BACKGROUND & AIMS: The increasing incidence of anal canal carcinomas requires better knowledge on anal human papillomavirus (HPV) infection. We aimed to assess anal canal HPV infection prevalence and risk factors among patients seen at a gastroenterology department in France. METHODS: We analyzed anal tissue samples collected from 469 consecutive patients (median age 54 years, 52% women), including 112 who received immunosuppressant therapies and 101 with inflammatory bowel disease (70 with Crohn's disease), who underwent colonoscopy examinations from April 1, 2012 to April 30, 2015...
