Anal canal cancer is a rare disease and squamous cell carcinoma is the most common histologic subtype. Traditionally, anal cancer is imaged with CT and PET/CT for purposes of TNM staging. With the increased popularity of MRI for rectal cancer evaluation, MRI has become increasingly utilized for...
By convention, the stage of the cancer is described using the TNM system as described by the International Union Against Cancer and in the AJCC Cancer Staging Manual. T describes the extent of the tumor. N denotes the presence, or absence, and extent of lymph node metastases. M refers to ...

Accurate inguinal and pelvic nodal staging in anal cancer is important for the prognosis and planning of radiation fields. There is evidence for the role of 18-fluorodeoxyglucose positron emission tomography (FDG-PET) in the staging and management of can
(PET)/CT. TNM staging was described according to the 8th edition of the American Joint Committee on Cancer staging system. Patient 1 was a 49-year-old woman diagnosed with stage pT1N1a ASCC. The patient underwent excisional biopsy. Pathologic examination revealed a 1.4 cm tumor and the ...
The extent of disease was rated using the current TNM classification of malignancies and restaged according to the 8th edition for the study purposes. Treatment protocol The planning CT and the irradiation were accomplished in the supine position. Contouring of target volumes and critical organs was...
