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.Pericolonic lymph nodes are "regional" lymph nodes for an ovarian primary. If you do not have enough information to assign codes 12-30, assign code 50 [Regional lymph nodes, NOS].

For cases diagnosed 2007 or later, assign histology code 8503 [Papillary adenocarcinoma]. Rule H14 applies.

ICD-O-3 code 8050 does not apply in this case. Refer to the numeric listing in ICD-O-3. 8050 is a squamous cell neoplasm. Papillary carcinoma of the breast is NOT a squamous cell neoplasm. It is a neoplasm of the breast parenchyma - ducts, lobules or connective tissue. 8503 is the correct code in this case.

For cases diagnosed 2007 or later, assign code 8340 [Papillary carcinoma, follicular variant] according to rule H15 for Other Sites.

"Predominantly" and "type" indicate specific histologies. "Variant" does not. See rule H13. The histology in this case is papillary and follicular. Tall cell variant is ignored.

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 or later, the 2007 MP/H rules apply if the 2008 diagnosis is a new tumor. Was there any statement that the patient was free of disease (NED) after the chemo and radiation therapy? (A patient can be disease free without surgery). If there is no statement to the contrary, no mention of metastasis from the 1998 diagnosis, and no mention of disease between 1998 and 2008, follow lung rule M8 and abstract the 2008 diagnosis as a new primary.

This lung case differs from the colon case discussed in the document titled "Quality Improvement Meeting August 2008." For the colon case, there was disease in 2003, 2005 and 2007. Based on the information provided, the 2007 diagnosis was not a new tumor because the patient was never free of disease. Therefore, the 2007 diagnosis is not a new primary. The number of reportable primaries was based on disease status over time, and was not based on the type of treatment given for the initial tumor (i.e., surgery or any other treatment modality).

For cases diagnosed prior to 1/1/2010:Because there is no cell indicator information, code 9 [cell type not determined] in the grade/cell indicator field. Do not code grade for lymphoma. For lymphoma and leukemia this field is the cell indicator.

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.

Code Multiplicity Counter to 02 [Two tumors present] for an epithelial ovarian primary involving both ovaries. Do not count the peritoneal implants; they are regional metastasis and not included in the multiplicity counter. An example like this will be added to the manual in the next revision.

For cases diagnosed 2007 or later:

Use the 2007 MP/H rules for urinary sites to assess diagnoses made in 2007-2014. Use the multiple tumors module to compare a diagnosis in 2007-2014 to an earlier diagnosis.

For the example above, start by comparing the left renal pelvis diagnosis in 8/07 to the earlier left ureter primary diagnosed 5/05. Start with rule M3. Stop at rule M8. The 8/07 renal pelvis diagnosis is not a new primary. Next, compare the 3/08 bladder tumor to the earlier left ureter primary diagnosed 5/05. Start with rule M3. Stop at rule M5. The 3/08 bladder tumor is a new primary because it is an invasive diagnosis following an in situ diagnosis. Use only the more recent of the two earlier urinary diagnoses for comparison. Do not compare the 2007 and later diagnoses to the 11/89 in situ bladder primary in this case.

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.
