Abstract
Physical examination is an important part of the staging and planning process as well as adequate imaging studies. For tumors that are palpable, attention should be paid as to how far the tumor begins from the anal verge. Standard studies include CT of the pelvis to assess the primary tumor and the status of regional lymph nodes. These tumors can be well-visualized on PET, so a PET/CT scan is becoming a standard part of staging and planning to help delineate the extent of gross disease. However, areas of low uptake on PET should not supercede physical exam fi ndings or abnormalities seen on CT.
