For cases diagnosed 2007 or later, two primaries are to be reported for this case. Rule M5 applies because there is a difference in the histology codes at the third digit.

Clarifications regarding histologic types of melanoma will be added to the rules when they are revised.

For cases diagnosed 2007-2014:

Based on the information provided, the primary site code for the 2004 primary should be C031 [mandibular gingiva, lower alveolar mucosa, etc.].

The 2007 diagnosis would be a separate primary according to rule M7 because the patient was disease free following treatment for the 2004 diagnosis. C031 and C060 are different at the third character.

For cases diagnosed prior to 1/1/2010, 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.

Code Primary Site to C779 [Lymph node, NOS]. In this case, there is no statement that lymphoma involves the lung. "Nonspecific parenchymal lung nodules" are not indicative of lymphoma involvement. Consequently, this cannot be assumed to be an extra-nodal lymphoma. Additionally, it is not clear whether or not the "borderline" pelvic lymph nodes are involved. If the physician cannot provide more information, follow instruction 4.e in the SEER manual on page 72.

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 2007 or later, this is two primaries.

MPH General Instructions tell us a pathologist may decide when there is recurrence when comparing the current tumor to a previous specimen. In this case, the pathologist did the comparison and documented that the second tumor is NOT a recurrence but a new primary.

Histologies described by the terms "pattern" and "component" do not indicate a more specific type when applying the histology rules. The histology for the 2009 diagnosis is adenocarcinoma [8140/3]. Rule H3 applies.

For this case, assign code C670 [Trigone of bladder]. The description for this case states that the tumor location is the base of the bladder. Base is a synonym for trigone.

The interureteric ridge (or interureteric crest, or interureteric fold) is a fold of mucous membrane extending accross the bladder between the two ureteric orifices. The trigone is located below the interureteric ridge.

Use code "6" for the CS LN evaluation field. As explained on page 113 in the 2007 SEER Manual, when post-operative disease is more extensive despite neoadjuvant therapy, this can be coded in the evaluation field. In this case, only an FNA was done on lymph nodes pre-operatively, but actual lymph nodes were removed and documented in the post-neoadjuvant excision of the lymph nodes which documented that they are histologically positive -- proving that the neoadjuvant therapy did not work.

In this case, neither the chemoembolization nor the liver transplant is part of the first course of therapy. The documented treatment plan was changed after disease progression. Chemoembolization was not part of the original treatment plan. First course therapy ends at this point.
