For cases diagnosed prior to 1/1/2010:

Plasma cell dyscrasia, NOS, is nonreportable. It is not a synonym for multiple myeloma. Plasma cell dyscrasia represents a broad spectrum of disease characterized by plasma cell proliferation that appears inappropriate or uncontrolled. Multiple myeloma is one disease type that falls into that classification. However, there are several other malignant and benign diseases also classified as such because of their immunoglobulin abnormalities. Reportability to SEER regarding a disease classified as a plasma cell dyscrasia is dependent on identifying the specific cell type associated with the disease in the ICD-O-3.

For cases diagnosed 2010 forward, 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 20 [Involvement of two or more lymph node regions on the same side of diaphram]. The AJCC lists mesenteric as a core nodal region, but does not list retroperitoneal lymph nodes as a part of this region, so retroperitoneal is a separate region.

The EOD staging scheme for lymphoma uses lymph node REGIONS as the criteria for assigning the extension code. Use the AJCC Cancer Staging Manual as the definitive source for classifying lymph node regions, not the ICD-O-3. If it is a separate LN region per the AJCC, it is coded in the EOD as a separate region.

According to the AJCC curator, the nodal regions are defined in Kaplan's book on Hodgkin disease. Bilateral cervical, or axillary, or hilar, or pelvic, or inguinal nodes count as two regions. Mediastinal and para-aortic lymph nodes count as one region regardless of laterality as they are centrally located. A large mediastinal mass constitutes one region involved regardless of the size.

For cases diagnosed between 1998-2003:

Extension into the aortico-pulmonary window, would be coded in the EOD-Extension field as 70 [mediastinal extension]. If the tumor extends into the paratracheal space, subcarina, or other areas listed under the code 2 in lymph nodes, code the EOD-Extension field to 70 to capture this type of involvement.

For tumors diagnosed prior to 2007:

Code the Histology field to 8500/3 [ductal carcinoma] unless the combination is ductal and lobular.

For tumors diagnosed 2007 or later, refer to the MP/H rules. If there are still questions about how this type of tumor should be coded, submit a new question to SINQ and include the difficulties you are encountering in applying the MP/H rules.

For tumors diagnosed prior to 2007:

For cases diagnosed on or after 1/1/2001: Code the Histology field to 8575/3 [metaplastic carcinoma]. Sarcomatoid is not coded as sarcoma.

The terms metaplastic carcinoma, squamous cell carcinoma and intraductal carcinoma are used, but only the metaplastic and squamous cell carcinomas are invasive. Metaplastic, loosely defined, means tissue that is not normal.

For tumors diagnosed 2007 or later, refer to the MP/H rules. If there are still questions about how this type of tumor should be coded, submit a new question to SINQ and include the difficulties you are encountering in applying the MP/H rules.

For tumors diagnosed prior to 2007:

Code the Histology field to 8201/3 [cribriform carcinoma]. The word "type" is a term that indicates majority of the tumor. The term "cribriform" would be a term used to determine the histology code.

For tumors diagnosed 2007 or later, refer to the MP/H rules. If there are still questions about how this type of tumor should be coded, submit a new question to SINQ and include the difficulties you are encountering in applying the MP/H rules.

For unknown primaries treated with a lymph node dissection and diagnosed 1/1/2003 and after, code:

1) Surgery to Primary Site: 98 [All unknown and ill-defined disease sites, WITH or WITHOUT surgical treatment].

2) Scope of Regional Lymph Node Surgery: 9 [Unknown or not applicable].

3) Surgical Procedure of Other Site: 1 [Surgery to other site(s) or node(s), NOS; unknown if regional or distant].

4) Radiation Sequence with Surgery: 3 [Radiation after surgery]. Any planned surgical treatment is used to code radiation/surgery sequence (per CoC I&R).

For cases diagnosed 1998 and later:

Code the Surgery of Primary Site field to 17 [Other method of local tumor destruction]. HIFU uses focused energy to destroy tissue. It is classified as a surgical procedure.
