Vitamin D is implicated in the etiology of cancers of the gastrointestinal tract, usually characterized by alteration in the APC/β-catenin/TCF tumor suppressor pathway. The vitamin D receptor (VDR) is also implicated in cardiovascular and skin diseases as well as in immunity. Activated VDR can indirectly alter β-catenin nuclear localization and directly suppress β-catenin/TCF mediated transcriptional activity. We treated VDR null mice with the carcinogen azoxymethane (AOM) and generated mice bearing a mutated APC (hypomorph) on a VDR null background (Apc1638N/+Vdr-/-)...

BACKGROUND: Laparoscopic surgery offers patients with rectal cancer short-term benefits and similar survival rates as open surgery. However, selecting patients who are suitable candidates for laparoscopic surgery is essential to prevent intra-operative conversion from laparoscopic to open surgery. Clinical and pathological variables were studied among patients who had converted laparoscopic surgeries within the COLOR II trial to improve patient selection for laparoscopic rectal cancer surgery...

A 78-year-old man visited our hospital with a prolapsed hemorrhoid. He was referred to the dermatology unit due to the thickness and redness of the perianal skin. He was diagnosed as having extra mammary Paget's disease by skin biopsy. After a biopsy of the anal polyp was performed to investigate the primary site, he was diagnosed with early anal canal cancer with Pagetoid spread and underwent a radical operation. Abdominoperineal resection with skin(D2 prx D3 lymphadenectomy) was performed with perineal reconstruction using a gracilis muscle graft...

OBJECTIVES: Although chemoradiation is the standard of care for anal cancer, limited data exist regarding pelvic reirradiation (re-RT) for recurrent disease. We investigated toxicity and outcomes in patients who received prior pelvic radiation therapy (RT), and subsequently underwent hyperfractionated accelerated re-RT to the pelvis for recurrent anal cancer. MATERIALS AND METHODS: We reviewed records of 10 patients with recurrent anal squamous cell carcinoma who previously received pelvic RT to at least 30 Gy as a component of their chemoradiation and underwent re-RT in 1...

Anal cancer is uncommon neoplasm with an incidence of 2 new cases per 100,000 per year in the USA, accounting approximately 0.4 % of all tumors and 2.5 % of gastrointestinal malignancies. An early detection of the anal cancer is crucial for the patient management, whereas the diagnosis at an early stage allows conservative management with sphincter sparing, on the contrary a delays in diagnosis might lead to an advance cancer stage at presentation with worst survival. According to National Comprehensive Cancer Network (NCCN) Anal Carcinoma guidelines the patients should be subjected to a careful clinical examination, including a digital rectal examination (DRE), an anoscopic examination, and palpation of inguinal nodes...

BACKGROUND AND AIMS: Extensive excision of the esophageal mucosa by endoscopic submucosal dissection (ESD) frequently evokes a luminal stricture. This study aimed to determine the efficacy of a high-density collagen patch for the prevention of esophageal stricture in extensive ESD. METHODS: Six pigs underwent circumferential esophageal ESD under general anesthesia. In 3 pigs, artificial ulcers were covered by 2 collagen patches. The other 3 pigs underwent circumferential ESD only...

Anal squamous cell cancer (SCC) is a relatively uncommon cancer in the United States. Anal SCC has long been associated with human immunodeficiency virus (HIV) positivity and/or men who have sex with men. The incidence of anal SCC has been increasing in both genders regardless of HIV status. Few clinicians are aware that white women, when not controlling for gender and sexual preference together, have the highest incidence of anal SCC. Anal intraepithelial neoplasia (AIN), dysplastic cells of the anal canal due to human papilloma virus infection, is believed to be the precursor to anal SCC...

Human papillomavirus (HPV) vaccines offer primary prevention of cervical cancer and protection against other HPV-associated cancers. HPV vaccine coverage in the United States (U.S.) remains low, particularly among older adolescents/young adults, and the uninsured. We assessed awareness and knowledge of HPV disease, HPV-related cancers, and HPV vaccines among working, uninsured adults. Data from the 2014 Health Information National Trends Survey (HINTS 4, Cycle 4) were used as a benchmark. Patients were surveyed in late 2014 at the Volunteers in Medicine free clinic in Duval County, Florida...

Squamous cell carcinoma of the anal canal (SCCA) remains a less common gastrointestinal malignancy despite a continued increase in the annual incidence in the United States and globally. The vast majority of all cases are attributed to persistent infection and integration into host cell DNA by human papillomavirus (HPV). For patients with metastatic anal cancer, there is currently no accepted consensus standard of care. Given the viral etiology associated with the oncogenesis of this tumor, great interest exists for the development of immunotherapy as a novel approach to improving clinical outcomes for patients afflicted with this disease...

Squamous cell carcinoma (SCC) of the anal canal is seldom diagnosed at an early stage. Chemoradiation therapy is a standard in Europe and the United States, though in squamous cell carcinoma there is no evidence-based therapy. In Japan, endoscopic submucosal dissection (ESD) is the standard minimally invasive treatment for early stage cancer of the digestive tract, including the colorectum. Therefore, if the lesion is diagnosed at an early stage, ESD may be selected for anal canal lesions. We experienced two cases of early stage anal canal cancer in which the diagnosis and the extent of the lesions were confirmed using magnifying endoscopy with narrow-band imaging (NBI), as well as performing ESD...

Rectal bleeding is very common in general population with a prevalence of 10-20 %. Primary care physicians have to stratify patients basing on urgency and on the colo-rectal cancer risk and to conduct a decision making for the correct management. We report a case of a 61-years-old woman, complaining rectal bleeding and an anal mass attended to their family doctor who does a visit but without a digital rectal examination and diagnosed a hemorrhoidal prolapse suggesting medical therapy. For the persistence of symptoms she comes to our service from emergency attention...

BACKGROUND: Cancer incidence and mortality projections are important for understanding the evolving landscape for cancer risk factors as well as anticipating future burden on the health service. METHODS: We used an age-period-cohort model with natural cubic splines to estimate cancer cases and deaths from 2015 to 2035 based on 1979-2014 UK data. This was converted to rates using ONS population projections. Modified data sets were generated for breast and prostate cancers...

Individuals with inherited immunodeficiencies, autoimmune disorders, organ or bone marrow transplantation, or infection with human immunodeficiency virus (HIV) are at increased risk of infection with both low-risk and high-risk human papillomavirus (HPV) types. Chronic immunosuppression provides an environment for persistent HPV infection which carries a higher risk of malignant transformation. Screening guidelines have been developed or advocated for processes that have detectable premalignant lesions, such as anal cancer or cervical cancer...
