How do I classify a patient who has metastatic melanoma in a cervical lymph node less than 3 cm in greatest dimension without a primary or other metastasis?
T0pN1M0, stage III. The staging is based on regional lymph node and/or distant metastasis status. In this case, the site of metastasis is assumed to be regional. 1.23 Neo-adjuvant therapy 1.23.1 In a case of rectal carcinoma after neo-adjuvant chemo-radiotherapy there is a group of tumour cells in the muscularis propria floating in a pool of mucin. Such pools abound and are also seen in the subserosal layer but are without tumour cells. What would be the ypT category of this tumour? Since the definition of the “y” factor states that it categorizes tumour that is actually present, select ypT2.
