Update to Derived Grade 2018

[howew]

The derived grade 2018 algorithm should be updated to add specific logic for Hematopoietic and Lymphoid Neoplasms.

Schemas covered by this include: • 00790 Lymphoma • 00795 Lymphoma-CLL/SLL • 00811 Mycosis Fungoides • 00812 Primary Cutaneous Lymphomas (excluding Mycosis Fungoides) • 00821 Plasma Cell Myeloma • 00822 Plasma Cell Disorders • 00830 HemeRetic

The priority order, from BEST to WORST, is: • 8, blank

The original issue for this algorithm can be found here: https://github.com/imsweb/algorithms/issues/160

The documentation in that issue was missing this part of the logic.

So the current logic is this:

if schema ID is 00480 (breast) and behavior is 2, use "H, M, L, 3, 2, 1, D, C, B, A, 9, blank" if schema ID is 00480 (breast) and behavior is 3, use "3, 2, 1, H, M, L, D, C, B, A, 9, blank" if schema ID is not 00480 (breast), use "S, 5, 4, 3, 2, 1, E, D, C, B, A, H, M, L, 9, blank"

Does it need to become this:

if schema ID is 00480 (breast) and behavior is 2, use "H, M, L, 3, 2, 1, D, C, B, A, 9, blank" if schema ID is 00480 (breast) and behavior is 3, use "3, 2, 1, H, M, L, D, C, B, A, 9, blank" if schema ID is 00790, 00795 (etc...), use "8, blank" if schema ID is not 00480 (breast) and not 00790, 00795, etc..., use "S, 5, 4, 3, 2, 1, E, D, C, B, A, H, M, L, 9, blank"

Does that look correct?

Is this needed for this upcoming February SEER submission?

[howew]

Yes, that looks right. I don't know if its needed for February or not, to be honest.

[schusslern]

yes, this looks good Fabian

[depryf]

These changes are done. Since this is not needed for this upcoming SEER submission, I am not going to force a release right away. There is another issue for updating the site-specific surgery lookups, I will wait for that one to be completed as well...
