Despite rare, metastatic anal carcinoma confers a poor prognosis. Systemic chemotherapy is the mainstay of treatment for advanced disease while the role of biologics and/or surgical resection of metastatic disease are anecdotal. Compared to isolated liver colorectal or neuroendocrine cancer liver metastases, there is far less experience with resection or nonsurgical local ablative procedures for patients with metastatic anal carcinoma to the liver. We report the case of a 67-year-old woman with metastatic anal carcinoma to the liver who was successfully treated with liver resection and remains free of relapse more than one year later...

Anoscrotal fistula is an extremely rare condition involving an epithelialised tract between the anal canal and scrotal wall. It is more commonly seen as a congenital phenomenon in the paediatric population, and has not previously been described in the literature in adults. We present the case of a man aged 52 years who developed a complex anoscrotal fistula after a radical inguinal orchidectomy for an intratesticular seminoma. A postsurgical wound-site infection developed into a chronically discharging wound refractory to antibiotic treatment prompting further investigation...

BACKGROUND: Several studies have described the course and anatomical relations of the pudendal nerve. Several surgical nerve decompression techniques have been described, but only the transgluteal approach has been validated by a prospective randomized clinical trial. The purpose of this study was to describe the course of the nerve and its variants in a population of patients with pudendal neuralgia in order to guide the surgeon in the choice of surgical approach for pudendal nerve decompression...

Purpose Squamous cell carcinoma of the anal canal (SCCAC) is characterized by high locoregional failure (LRF) rates after sphincter-preserving definitive chemoradiation (CRT) and is typically associated with anogenital human papilloma virus infection. Because cetuximab enhances the effect of radiation therapy in human papilloma virus-associated oropharyngeal squamous cell carcinoma, we hypothesized that adding cetuximab to CRT would reduce LRF in SCCAC. Methods Sixty-one patients with stage I to III SCCAC received CRT including cisplatin, fluorouracil, and radiation therapy to the primary tumor and regional lymph nodes (45 to 54 Gy) plus eight once-weekly doses of concurrent cetuximab...

Extramammary Paget's disease (EMPD) is a rare disease which is found in apocrine-rich locations such as anogenital region, axilla and rarely in other sites. Perianal EMPD is often reported as the involvement of perianal skin, but involvement of anal mucosa is very rare. Based on pathogenesis and association with either synchronous or metachronous malignancy, EMPD can be divided into primary and secondary types. Treatment approach for these two types of Paget's disease and their prognosis is different, thus it is important to make the distinction...

BACKGROUND: Faecal incontinence (FI) is both a medical and social problem, with an underestimated incidence. For patients with internal anal sphincter damage, implantation of biomaterial in the anal canal is a recognised treatment option. One such material, Gatekeeper™, has previously shown promising short- and medium-term results without any major complications, including displacement. The main aim of the present study is to assess the degree to which displacement of Gatekeeper prostheses may occur and to determine whether this is associated with patient outcomes...

INTRODUCTION: Gastrointestinal stromal tumors (GIST) are tumors of mesenchymal origin commonly detected in stomach and small bowel. GIST arising primarily from the anal canal is extremely rare. Due to the malignant potential, these tumors are treated with radical surgery like abdominoperineal resection. But with the advent of imatinib therapy and a better understanding of the tumor biology, some cases have been successfully treated with wide local excision. PRESENTATION OF CASE: We describe a case of a 70-year-old lady presenting with a 2cm mass in the anal canal...

INTRODUCTION: Continence results from a complex interplay between anal canal (AC) muscles and sensory-motor feedback mechanisms. The AC's passive ability to withstand opening pressure - its compliance - has recently been shown to correlate with continence. Functional lumen imaging probe (FLIP) is used to assess AC compliance, although it provides no anatomical information. Therefore, compliance assessment of specific anatomical structures has not been possible, and the anatomical position of critical functional zones remains unknown...

BACKGROUND: Anal fissure is a tear in the epitelial lining of the anal canal. This is a very common anorectal disorder, but the choice of treatment is unclear. Sphincterotomy is effective but it is affected by a high risk of faecal incontinence. Manual anal stretch is a efficacious, economic and safe maneuver. The aim of this prospective study was to assess the safety and effectiveness of anal stretch in resolving chronic anal fissures. METHODS: Twenty five patients with a clinical diagnosis of chronic anal fissure were submitted to anal stretch...

Etiologically linked to HPV infection, malignancies of the anal canal have substantially increased in incidence over the last 20 years. Although most anal squamous cell carcinomas (SCC) respond well to chemoradiotherapy, about 30% of patients experience a poor outcome, for undetermined reasons. Despite cumulative efforts for discovering independent predictors of overall survival, both nodal status and tumour size are still the only reliable factors predicting patient outcome. Recent efforts have revealed that the biology of HPV-related lesions in the cervix is strongly linked to the originally infected cell population...

AIM: This study aimed to assess the ability of preoperative axial computed tomography (CT) to predict surgical difficulty in bringing the ileal pouch to the level of the anus during restorative proctocolectomy (RPC). METHOD: Patients who underwent RPC with an ileal pouch-anal anastomosis (or ileal pouch-anal canal anastomosis) in our institution between January 2008 and April 2014 were enrolled. The patients were divided into two groups, including those in whom CT indicated potential difficulty in extending the pouch downwards (extension difficult (ED) group) and patients with no CT evidence of potential difficulty (normal group)...

Squamous cell carcinomas of the anus and anal canal represent a model of a cancer and perhaps the first where level 1 evidence supported primary chemoradiotherapy (CRT) in treating locoregional disease with curative intent. The majority of tumours are associated with infection with oncogenic subtypes of human papilloma virus and this plays a significant role in their sensitivity to treatment. However, not all tumours are cured with CRT and there remain opportunities to improve outcomes in terms of oncological control and also reducing late toxicities...

Specific human papillomavirus genotypes are associated with most ano-genital carcinomas and a large subset of oro-pharyngeal carcinomas. Human papillomavirus DNA is thus a tumour marker that can be detected in the blood of patients for clinical monitoring. However, data concerning circulating human papillomavirus DNA in cervical cancer patients has provided little clinical value, due to insufficient sensitivity of the assays used for the detection of small sized tumours. Here we took advantage of the sensitive droplet digital PCR method to identify circulating human papillomavirus DNA in patients with human papillomavirus-associated carcinomas...

BACKGROUND: Acne inversa (AI), also called hidradenitis suppurativa, is a chronic, inflammatory, recurrent skin disease of the hair follicle. Familial AI shows autosomal-dominant inheritance caused by mutations in the γ-secretase genes. This study was aimed to identify the specific mutations in the γ-secretase genes in two Chinese families with AI. METHODS: In this study, two Chinese families with AI were investigated. All the affected individuals in the two families mainly manifested with multiple comedones, pitted scars, and a few inflammatory nodules on their face, neck, trunk, axilla, buttocks, upper arms, and thighs...

BACKGROUND: Three-dimensional high-resolution anorectal manometry (3DHRAM), used for exploring anorectal disorders, was recently developed, providing interesting topographic data for the diagnosis of pelvic floor disorders such as excessive perineal descent. The aim of our study was to define a diagnostic strategy based on selected 3DHRAM parameters to identify rectal intussusceptions (RI), considering conventional defecography (CD) as the gold standard. METHODS: All patients referred to our center in the previous 6 months for 3DHRAM to explore fecal incontinence or constipation, and who previously achieved CD, were eligible...

REVIEW
Rob Glynne-Jones, Sheela Rao
Radical concurrent chemoradiotherapy with 5-fluorouracil and mitomycin C (MMC) remains the standard of care for squamous cell carcinoma of the anus. Phase III trials over 2 decades have used combined radiation doses of 50 to 60 Gy with concurrent fluoropyrimidines, MMC, or cisplatin in various doses and schedules. Modern radiotherapy techniques allow the production of highly conformal plans, decreasing radiation doses to the organs at risk and ensuring a shorter overall treatment time without the need for treatment breaks...
