The Solid Tumor Rules for Lung rule H4 applies. Per Table 3, page 12, third column on adenocarcinoma row, adenocarcinoma, acinar predominant is coded to 8551/3.

For cases diagnosed 1998-2003:

Code the EOD-Extension field to 12 [microinvasion] when there are no depth of invasion measurements given.

Code the EOD-Extension field to 11 [minimal microscopic stromal invasion] when there is a statement of "minimal STROMAL invasion."

For cases diagnosed 1998-2003:

For Primary Site and EOD, CT information has higher priority than laryngoscopy. The CT scan gives a better picture of the involvement of the deeper tissues. A laryngoscopy falls into the "physical exam" category more than the "operative" category. The laryngoscopy report is not an "operative" report like those generated from a surgical procedure.

Any treatment that destroys or modifies cancer tissue should be recorded as the appropriate type of treatment -- chemo, immuno, etc. Even if immunotherapy is given for symptoms/palliative treatment, it is likely to kill off tumor cells.

This answer was provided in the context of CSv1 coding guidelines. The response may not be used after your registry database has been converted to CSv2.

Lymph nodes with metastases greater than 0.2 mm are counted as positive. Code in CS Lymph Nodes and CS Regional LN Positive. Do not code ITC's greater than 0.2 mm in CS Site Specific Factor 4.

For cases diagnosed prior to 1/1/2010:Without further information, the term "myelodysplasia" alone is not reportable. If a more definitive diagnosis is made later, the case may become reportable.

For cases diagnosed 1/1/10 and later, refer to the Hematopoietic and Lymphoid Neoplasm Case Reportability and Coding Manual and the Hematopoietic Database (Hematopoietic DB) provided by SEER on its website to research your question. If those resources do not adequately address your issue, submit a new question to SINQ.

For cases diagnosed 1998-2003:

Code the EOD-Extension field to 55 [Invasion of/through serosa and adjacent connective tissue]. The description states the tumor extended through the serosa into periserosal tissue. The periserosal tissue in this case refers to adjacent connective tissue lying exterior to the intestinal wall and not the (sub)serosal tissue that lies exterior to the muscularis but inferior to the serosa. Analyze each case individually since pathologists are not consistent when using the above terminology.

Use code 12 in the Hematologic Transplant & Endocrine Procedures data field. Per the NCI, this procedure is an allogeneic transplant.

Rather than wiping out a patient’s immune system before transplanting donor bone marrow, doctors administer just enough chemotherapy to suppress the immune system, which keeps patients from rejecting the donated marrow without harming their organs. The procedure requires just a half-match, meaning that a patient’s parents or children could be suitable donors. AKA: Half-match transplants.
