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...

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...

OBJECTIVE: Leukocytosis and neutrophilia could be the tip of the iceberg in the inflammatory tumor microenvironment. We aimed to validate their prognostic significance in a cohort of patients treated with definitive chemoradiation for anal squamous cell carcinoma (SCC). MATERIALS & METHODS: Clinical records from all consecutive patients treated in a single institution between 2006 and 2016 with curative-intent radiotherapy were retrospectively analyzed. Leukocytosis and neutrophilia, defined as leukocyte or neutrophil count over 10,000 and 7500/mm(3), respectively, were studied in terms of overall survival (OS), progression (PFS), locoregional (LFS) and distant (DFS)-free survival...

AIMS: Verrucous carcinoma (VC) is a variant of well differentiated squamous cell carcinoma and is in the anal region regarded as synonymous with giant condyloma (Buschke-Löwenstein tumor) (BLT). Etiology, diagnostic criteria and clinical behavior of both lesions are controversial. Recent studies suggest that VC at other sites is not associated with human papillomaviruses (HPV). We hypothesized that anal VC is also not related to HPV, while BLT is a HPV-induced lesion. METHODS AND RESULTS: Ten cases of VC and 4 cases of BLT were included...

CASE DESCRIPTION 5 dogs between 9 and 11 years of age were evaluated for treatment of primary (n = 2) or metastatic (3) hepatic neoplasia. CLINICAL FINDINGS Patients were evaluated on an elective (n = 3) or emergency (2) basis. Two dogs with primary hepatic neoplasia were evaluated because of lethargy and inappetence. One dog was referred after an enlarged anal sac was detected via palpation per rectum during a routine physical examination. Two dogs were evaluated on an emergency basis because of lethargy and weakness, and hemoabdomen in the absence of a history of trauma was detected...

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...

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

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...

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...

Anal canal cancer is rather an uncommon disease but its incidence is increasing. Squamous cell carcinoma (SCC) is the most frequent primary anal neoplasm and can encompass a variety of morphologies. HPV infection has a key role in precancerous lesions and cancer development by the production of E6 and E7 oncoproteins. Anal squamous precancerous lesions are now classified according to the same criteria and terminology as their cervical counterparts. The p16 expression by immunohistochemistry is a surrogate marker for human papilloma virus (HPV)...

Van Morris, Cathy Eng
Squamous cell carcinoma of the anal canal (SCCA) represents an orphan disease. Although prior infection with human papilloma virus is associated with the development of SCCA, knowledge of this relationship has proven ineffective in identifying therapeutic agents that have activity in the management of metastatic SCCA. Combination chemotherapy with traditional cytotoxic agents has demonstrated efficacy in multiple small series. However, immune checkpoint blockade agents have demonstrated efficacy for patients with refractory metastatic SCCA; these agents hold promise in the horizon for patients with metastatic SCCA...

Epidermal growth factor receptor (EGFR) is usually expressed in squamous cell anal carcinoma (SCAC) and anti-EGFR agents could represent a valid treatment strategy, also considering that KRAS and BRAF mutations are rare events in this type of cancer. However, no data are available on NRAS status in SCAC. In this study we analyzed NRAS status (exons 2-4) by Pyrosequencing in a case series of 50 SCAC patients previously characterized in our laboratory for KRAS, BRAF, PIK3CA mutations and HPV and HIV infections...

Transanal total mesorectal excision (TaTME) offers great potential for the treatment of malign and benign diseases. However, laparoscopic-assisted TaTME in ulcerative colitis has not been described in more than a handful of patients. We present a 47-year-old highly comorbid female patient with an ulcerative colitis-associated carcinoma of the ascending colon and steroid-refractory pancolitis. A two-stage restorative coloproctectomy including right-sided complete mesocolic excision was conducted. The second step consisted of a successful nerve-sparing TaTME and a handsewn ileal pouch-anal anastomosis...

PURPOSE: Squamous cell carcinoma of the anal canal (ASCC) accounts for 2-4% of gastrointestinal (GI) malignancies in the US and is increasing in incidence; however, genomic features of ASCC are incompletely characterized. Primary treatment of ASCC involves concurrent chemotherapy and radiation (CRT), but the mutational landscape of resistance to CRT is unknown. Here, we aim to compare mutational features of ASCC in the pre- and post-CRT setting. EXPERIMENTAL DESIGN: We perform whole exome sequencing of primary (n=31) and recurrent (n=31) ASCCs and correlate findings with clinical data...
