How does one classify “carcinoma in situ” and “high grade dysplasia in Barrett esophagus” and in “colon polyps”?
Our registry consultant provided the following: SEER rules say that high-grade dysplasia per se and severe dysplasia per se are not reportable to cancer registries. However, if the diagnosis is stated as “high-grade dysplasia (carcinoma in situ)”, the case is reportable as 8140/2 based on the carcinoma in situ part of the diagnosis; in TNM it would be Tis. 1.3 Clinical and pathological stage A patient has a needle biopsy of a left upper lobe mass that is positive for squamous cell carcinoma. A CT of the thorax shows a 4-cm left upper lobe mass >2 cm from the carina. The clinical category is cT2. What is the pathologic classification? Biopsy alone is not sufficient for pathological staging in this instance. Resection of the primary tumour is needed for pT1 or pT2 lung tumours to define their limits. Biopsy, without resection, could be used, for example, for pT4 (showing invasion of the oesophagus). 1.
