Answer:
For cases diagnosed 1998-2003:
Code the EOD-Size of Primary Tumor field to 013 [1.3 cm]. Code the size of a mass or nodule only when there is pathologic confirmation of malignancy. In the case you mention, the nodules were pathologically confirmed as cancer, so you would code the size of the largest nodule. If a nodule/or mass in the prostate is confirmed as cancer by needle biopsy, you would code the size of the mass or nodule.
