title: [Cancer of the anus. Analysis of our surgical experience].
abstract: BACKGROUND
  The different histological varieties of anal cancer due to the presence of different histogenesis tissue can be anatomically distinguished from anal canal tumours by their growth in a periorificial or marginal site. The first appearance of symptoms are common to usual non-tumoral pathologies, but can be ascertained at an early stage using biopsy. Anal cancer can be treated with surgery, conservative or radical treatment, radiotherapy alone and radiochemotherapy with possible surgery.
  
  
  METHODS
  Based on the results obtained by radical surgical exeresis due to the frequent spread of tumours to the pelvis and the possibility of metastases in the cava and portal vein, current therapeutic possibilities were analysed in 101 patients with anal cancer undergoing abdominal-perineal surgery. The priority of radiochemotherapy was underlined, reserving the faculty of surgical treatment for cases of large tumours with insufficient penetration.
  
  
  RESULTS
  The choice of therapy should be modulated according to its histology, tumour site, increase and grading. Only surgery can ensure long-term results similar to those obtained using surgical treatment of rectal cancer.
  
  
  CONCLUSIONS
  For the best results the authors recommend a therapeutic approach which involves some methods used for an early diagnosis.
