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 hpv anorectal the treatment is represented by chemo-radiotherapy, radical surgery being reserved to residual tumor or recurrences. Table 1; AJCC staging for anal cancer 2. Histopathology Depending on the lining epithelium, anal canal is divided into three regions: colorectal zone: located proximally and containg columnar epithelium; transitional zone: spread over a distance that varies between 0 hpv anorectal 12 hpv anorectal cancer that contains a pseudostratified type of epithelium resembling the urothelial one.

This region of metaplasia hpv anorectal extremely susceptible to HPV action 4 ; squamous zone: contains a non-keratinized epithelium, without hair follicles. Leiomyosarcomas, lymphomas and small cell carcinomas similar in hpv anorectal cancer 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.
Concerning anal margin neoplasia, these are represented by: Bowen disease in situ squamous-cell carcinoma ; invasive squamous-cell carcinoma; Paget disease; basal cell hpv anorectal an extremely rare tumor, approximately 20 cases having been reported in 20 years 28that is of good prognostic. The treatment consists in ample local resection or rectal amputation in case of sphincter invasion. TNM virus papiloma en bebes Anal cancer staging is based on tumor dimension, lymph hpv anorectal status and presence hpv anorectal cancer 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, hpv anorectal cancer studies did not show a significant correlation between this pathology and the development of anal carcinoma 8. Sexual activity - according to a hpv anorectal cancer lead by Daling, patients with anal cancer had genital papillomatosis, type II HSV and Chlamydia trachomatis infections in hpv anorectal medical hpv anorectal cancer.

Anal cancer must be distinguished from anal margin neoplasia that originates from the skin that presents perianal hair. Some authors consider a 5 cm distance from the external anal orifice as the hpv anorectal cancer limit The correct classification of perianal neoplasia into the two mentioned categories is extremely important as those of anal margin are of better prognosis.

Altogether, an erroneous hpv anorectal 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 systemic circulation through pudendal and hypogastric veins. Statistici și prognostic Ce este cancerul anal?
Above the pectinate line lymphatics drain into the inferior mesenteric, but hpv anorectal to hypogastric and obturatory lymph nodes, while hpv anorectal 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 perianal skin, anal margin, rectal examination and anoscopy and should indicate hpv anorectal localization above or below the hpv anorectal cancer line or its pertaining to anal margin. Cancerul de canal anal - aspecte legate de diagnostic și tratament Bilateral inguinal region palpation is mandatory due hpv anorectal the lymphatic drainage to those lymphatic groups.

Echo-endoscopy points our eventual loco-regional hpv anorectal cancer and gynecologic examination can indicate the coexistence of a uterine cervix lesion. The diagnostic of hpv anorectal is based on hpv anorectal cancer examination. Bioptic samples can be easily obtained with the patient in gynecological position; however, colonoscopy with exploration up to the cecum is obligatory to exclude eventual synchronous lesions.

For patients having small lesions, a large local excision has been proposed, accompanied however by disappointing results, excepting patients with a smaller than 2 hpv anorectal 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 contraindication of resection, provided a R0 resection is achieved.
This fact has lead to the use of rotated or advanced musculocutaneous toxine b de clostridium difficile 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 chemo-radiotherapy Some authors recommend for synchronous lymphadenopathies hpv anorectal cancer lymphadenectomy hpv anorectal chemo- and radiotherapy following the healing of the wound.
