CS Site Specific Factor 3--Prostate: When a prostatectomy specimen shows tumor focally penetrating through the capsule into periprostatic striated muscle tissue, is the involvement coded to 041 [periprostatic tissue] or 052 [skeletal muscle, NOS]?
CS Eval--All Sites: If any of the CS fields (TS/Extension, LN, or Mets) are based on the TNM and there is no text documenting the basis for the evaluation, are the evaluation fields coded to 0 instead of 1?
CS Extension--Lung: Do notes 6A and 6B in the 2004 SEER manual offer conflicting instruction for determining the significance of pleural effusion for this primary site? See Discussion.
CS Eval--Lung: How is the CS Reg Nodes Eval field to be coded when the FNA of a paratracheal lymph node is positive for adenocarcinoma and the patient subsequently undergoes neoadjuvant chemoradiation therapy followed by an excision of multiple lymph node fragments that show adenocarcinoma? See Discussion.
CS Extension--Bladder: How would the following statements be coded for bladder extension -- Code 03 [inferred description of non-invasion] vs code 15 [invasive confined to subepithelial connective tissue]. See Discussion.
CS Tumor Size--Breast: Is the largest focus or the total area coded for tumor size in a patient presenting with "scattered foci of DCIS, largest focus measuring 0.6cm. DCIS spans a total area of 2.1cm."
