Segments 2, 3, and 4 correspond to the left lobe of the liver. Segments 5, 6, 7 and 8 correspond to the right lobe of the liver. Segment 1 is the caudate lobe, which has completely different drainage and vascularization, is separate from the larger right and left lobes.

For cases diagnosed 1998-2003: Since segments 5 and 7 are both in the right lobe, assign EOD-extension code 30 for the case above, unless there is mention of vascular invasion. Be sure to record the size of the largest primary tumor.

Tumor size and vascular invasion are the most important factors for AJCC 6th edition staging.

For tumors diagnosed 1998-2003:

Based on the information provided:

The topography code for this lymphoma is C772 [Intra-abdominal lymph nodes].

Code SEER Summary Stage 2000 to 5 [Regional NOS].

Code EOD Extension to 20. More than one lymph node region below the diaphragm is involved (retroperitoneal and peritoneal). The organs mentioned are not involved by the lymphoma. The bulk of the masses is causing obstruction by displacing and/or encasing organs.

A physician description of "bulky disease" would not change the EOD for this case.

For cases diagnosed 2010 and forward, access the Hematopoietic Database at http://seer.cancer.gov/seertools/hemelymph.

Code the histology to 9695/3 [follicular lymphoma, grade 1] per PH29.

Under the Alternate Names section of the Heme DB, B-cell non-Hodgkin lymphoma is synonym for non-Hodgkin lymphoma, NOS and B-cell lymphoma, NOS.

Per PH29, one codes the histology when there is one non-specific histology (NHL, NOS) and one specific histology (FL, grade 1). You are also required to confirm the specific and the non-specific (NOS) histology represent the same primary using the Multiple Primaries Calculator. The calculator indicates these are the same primary.

Code the oncologist's clinical diagnosis of peripheral T-cell lymphoma.

The definition for this neoplasm is "A large group of lymphomas which we collectively refer to as peripheral T-cell lymphomas with the optional addition of "unspecified" to emphasize that these cases do not belong to any better defined entities. Attempts to distinguish between them on morphological basis have met with poor reproducibility."

Per the Abstractor Notes in the Heme DB: Patients present with peripheral LN involvement. The diagnosis of PTCL, NOS is made ONLY when other specific entities have been explored.

This fits your case; attempts to find a more specific disease (flow cytometry; BM biopsy) were negative and gave no further information that could be used to assign a more specific classification.

Contact the physician for clarification of the term "pancreatobiliary." If no further information can be obtained for this case, assign code C249 [Biliary tract, NOS] based on the CT findings for the specific case in this question.

When the primary is described as "pancreatobiliary" with NO FURTHER INFORMATION, assign C269.

Assign histology code 8246/3 and assign code 9 for grade.

Since the primary is unknown and the type of NEC is not definitively stated, code neuroendocrine carcinoma, NOS based on the diagnosis.

Code grade from primary tumor only. Assign grade code 9 when the primary site is unknown. See instruction 2.b. in the Grade Coding Instructions for 2014+.

SINQ 20170033 and SINQ 20160023 provide instructions for coding the grade/differentiation field. Using these SINQ questions to code histology could lead to errors.

Instructions for First Course of Therapy include using the documented first course of therapy (treatment plan) from the medical record. While a patient may weigh in on the treatment decision, the physician is responsible for developing and managing the treatment plan including closely watching a patient’s condition but not giving treatment unless symptoms appear or change.

We can add language to a future manual to clarify.

Instruction #5 in the Priority Order for Using Documentation to Identify Histology of the Head and Neck Solid Tumor Rules, Item 5.B., refers to cytology in the documentation though cytology is not listed before this. In H&N tumors, cytology is usually performed on lymph nodes and seldom on a primary tumor. Cytology will be added to H&N in the next update.

This case is reportable. The diagnosis states "suspicious for adenocarcinoma." "Suspicious for" is a reportable ambiguous term.

The additional stains supported this "suspicious" diagnosis. A more definitive diagnosis could not be made based on this specimen.

For cases diagnosed 2007 or later:

Abstract as separate primaries:

• 12/2004 pineocytoma (9361/1)

Complete two abstracts when a previously diagnosed non-malignant tumor transforms or progresses to a malignancy. Refer to the CDC/NPCR guidelines for Data Collection of Primary Central Nervous System Tumors, 2004. Malignant transformation is discussed on page 50.
