Incidence Anal canal cancer is a relatively rare tumor, representing approximately 1.
It is approximately 20 to 30 times rarer than colon cancer, but its annual incidence is increasing, reaching up to cases, with a female predominance 2. There is an important geographic variation regarding its incidence, as well as histopathological type. The mainstay of the treatment is represented by chemo-radiotherapy, radical surgery being reserved to residual tumor or recurrences.

Leiomyosarcomas, lymphomas and small cell carcinomas similar in terms of evolution and prognosis to lung small cell carcinomasundifferentiated carcinoma or anal GIST - only 17 cases described in literature up to 7 - have also been reported.
The treatment consists in ample local resection causes of rectal cancer hpv rectal amputation in case of sphincter invasion.

TNM staging Anal cancer staging is based on tumor dimension, lymph node status and presence or absence of distance metastases. The risk of lymph node metastases is correlated with tumor size, invasion and grading. Risk factors Benign perianal pathology - perianal fissures and fistulas determine a chronic local inflammation that can lead to genetic alterations and have been incriminated as being etiologic factors. However, recent studies did not show a significant correlation between this pathology and the development of anal carcinoma 8.

Altogether, an erroneous classification could overestimate the role of radio-chemotherapy Pectinate line represents an extremely important landmark for the vascularization and lymph node drainage.
Thus, above this line, venous drainage is to the portal circulation, by way of inferior mesenteric vein and below venous blood drains into causes of rectal cancer hpv circulation through pudendal and hypogastric veins.
Vaginal cancers and human papilloma virus Above the pectinate line lymphatics drain into the inferior mesenteric, but also to hypogastric and obturatory lymph nodes, while below pectinate line-especially to inguinal lymph nodes, but also to femoral ones Due to the resemblance to benign perianal pathology, the diagnosis is too often delayed.
Clinical examination consists in the inspection of causes of rectal cancer hpv skin, anal margin, rectal hpv causes rectal cancer and anoscopy and should indicate tumor localization above or below the pectinate line or its pertaining to anal margin.

For patients having small lesions, a large causes of rectal cancer hpv excision has been proposed, accompanied however by disappointing results, excepting patients with a smaller than 2 cm anal margin cancer Abdominoperineal rectal amputation is the standard salvage therapy for patients who develop local recurrences.
Tumor invasion into neighboring organs is not a hpv causes rectal cancer of resection, provided a R0 resection is achieved. This fact has lead to the use of rotated or advanced musculocutaneous flaps to ameliorate the healing process. Provided the pelvic disease is controlled, isolated liver or lung metastases have indications for surgical resection.
Due to significant morbidity and the relatively low impact on survival, prophylactic inguinal lymphadenectomy is not recommended Inguinal lymphadenectomy is indicated for patients with voluminous lymphatic blocks or to those with an obvious lymphadenopathy after causes of rectal cancer hpv Some authors recommend for synchronous lymphadenopathies inguinal lymphadenectomy with chemo- and radiotherapy following the healing of the wound.
