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--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 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 Extension--Brain and CNS: How is this field coded for a malignant tumor presenting as a confluent lesion over right parietal, posterior frontal and thalamic regions?
