I'm posting the information that I received from CAP regarding
specific protocols. I'll list them each separately by cancer site
for ease of reference.

For The Hodgkin lymphoma questions, as you can see below, you have
the option of specifying which specific lymph node site was biopsied
or state site not specified. And as for the tumor size, you can
either give a dimension if you know it is only one node and it was
all taken out you can specify a size, otherwise you can state cannot
be determined and write in a comment why. As for node regions
involved and other organ involvement, you can state it if you have
pathologic tissue involvement, otherwise you can say not specified.
See example below:

Tumor Site (check all that apply)
___ Lymph node(s), site not specified
_X_ Lymph node(s)
Specify site(s): __Right axillary lymph node_______________
___ Other tissue(s) or organ(s)
Specify site(s): _______________________

Tumor Size (largest single mass)
Greatest dimension: ___ cm
*Additional dimensions: ___ x ___ cm
Specify site: ________________________________
_X_ Cannot be determined (see Comment)

Extent of Pathologically Examined Tumor (check all that apply)
___ Involvement of a single lymph node region
Specify site: ____________________________
___ Involvement of multiple lymph node regions
Specify: _______________________________
___ Splenic involvement
___ Liver involvement
___ Bone marrow involvement
___ Other organ involvement
Specify: _______________________________
_X_ Not specified

Comment: Although the neoplasm measures 4.5 cm in the biopsied
lymph node, it uncertain whether other lymph nodes are involved and
a definitive size cannot be determined.
