MP/H Rules/Histology--Lung: How many primaries are accessioned if a pathology report for a right upper lobectomy with a chest wall resection describes the disease as 1) two foci of poorly differentiated non-small cell carcinoma, 2) mixed adenocarcinoma and non-mucinous bronchioalveolar carcinoma, each present as a separate focus? See Discussion.

This case was abstracted as two primaries, adenocarcinoma, acinar and papillary types [8255/3] and non-mucinous bronchioloalveolar carcinoma [8252/3] per Rules M5 and M10. If this is reported as only two primaries, what is the stage for each tumor? The non-small cell tumors were the most invasive, but they were not a separate primary per Rule M10.

Final pathology diagnosis for a RUL lobectomy and chest wall resection: Carcinoma of the lung with the following features:

1. Non-small cell carcinoma, poorly differentiated (see comment). Two foci in same lobe: 10 cm and 3 cm (largest dimensions of each tumor). Invades pleura (PL3), main bronchus and chest wall invasion present.

2. Adenocarcinoma and bronchioloalveolar carcinoma (see comment). Histologic subtype: Acinar and papillary (adenocarcinoma); non-mucinous (BAC). Two foci in same lobe: up to 1.0 cm. Pleural invasion absent, chest wall invasion absent.

3. Metastatic carcinoma in 5/7 peribronchial LN's.

Two histologically distinct neoplasms identified in the lobectomy/chest wall resection specimen: Poorly differentiated non-small cell carcinoma, present as two foci; and adenocarcinoma and non-mucinous bronchioloalveolar carcinoma, each present as a separate focus.

SEER will answer the question about the number of primaries to accession. Submit questions about stage to the CoC CAnswer Forum.

For cases diagnosed 2007 or later: Accession two primaries: a mixed adenocarcinoma, acinar and papillary types [8255/3] and a bronchioloalveolar carcinoma, non-mucinous [8252/3].

The steps used to arrive at this decision are:

Determine the histology code for each tumor prior to applying the Multiple Primary Rules to determine the number of primaries to accession. There are two non-small cell carcinomas, NOS; the histology code for these two tumors will be 8046/3. There is a single adenocarcinoma with acinar and papillary subtypes tumor, the histology for this tumor will be 8255. There is a single bronchioloalveolar carcinoma, non-mucinous subtype tumor; the histology for this tumor will be 8252/3.

Open the Multiple Primary and Histology Coding Rules manual. Choose one of the three formats (i.e., flowchart, matrix or text) under the Lung Multiple Primary rules to determine the number of primaries.

Start at the MULTIPLE TUMORS module, Rule M3, because this patient has multiple tumors. The rules are intended to be reviewed in consecutive order within the module (from Rule M3 to Rule M12 in this case). Stop at the first rule that applies to the case you are processing. This patient's adenocarcinoma with acinar and papillary subtypes [8255/3] and non-mucinous bronchioloalveolar carcinoma [8252/3] are multiple primaries.

Perform a second pass through the Multiple Primary rules to determine whether the two non-small cell carcinomas [8046/3] are multiple primaries or manifestations of the same primaries identified in Step 3.

Start at Rule M3 again because this patient has multiple tumors. Again, these rules are intended to be reviewed in consecutive order within the module (from Rule M3 to Rule M12 in this case). Stop at the first rule that applies to the case you are processing. This patient's non-small cell carcinomas, NOS [8046/3] are a single primary when compared to the adenocarcinoma with acinar and papillary subtypes [8255/3] and non-mucinous bronchioloalveolar carcinoma [8252/3]. Both of these histologies are more specific types of non-small cell carcinoma per the Lung Histology Groups and Specific Types Chart (Chart 1).

You can also apply Rule M10 for both non-small cell carcinoma, NOS [8046/3] compared to adenocarcinoma with acinar and papillary subtypes [8255/3] and non-small cell carcinoma, NOS [8046/3] compared to non-mucinous bronchioloalveolar carcinoma [8252/3].

Multiple primaries--Heme & Lymphoid Neoplasms: How many primaries are reported if a patient originally diagnosed with CLL is subsequently diagnosed several months later on a bone marrow biopsy with Richter's syndrome that transformed into a large cell lymphoma? See Discussion.

Per reviewed resources, the described condition is rare. Should the histology remain CLL or be changed to large cell lymphoma?

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

This case is accessioned as two primaries per Rule M10 which states to abstract multiple primaries when a neoplasm is originally diagnosed as a chronic neoplasm and there is a second diagnosis of an acute neoplasm more than 21 days after the chronic diagnosis. The first primary is CLL [9823/3] and it is a chronic neoplasm. The second primary is diffuse large B-cell lymphoma (DLBCL) [9680/3] and it is an acute neoplasm.

Richter syndrome (RS) is a complication of B cell chronic lymphocytic leukemia (CLL) or hairy cell leukemia (HCL) in which the leukemia changes into DLBCL. There is also a less common variant in which the CLL changes into a Hodgkin lymphoma. Richter's transformation affects about 5% of CLL patients. Richter syndrome is listed under the Alternate Names section in the Heme DB for diffuse large B-cell lymphoma [9680/3].

20110033 Multiple primaries--Heme & Lymphoid Neoplasms: How many primaries are to be abstracted when a right parotid mass shows "MALT Lymphoma with transformation to Diffuse Large B-cell Lymphoma" but the patient has no known history of MALT lymphoma?

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

This is a single primary per Rule M4 which states to abstract a single primary* when two or more types of non-Hodgkin lymphoma are simultaneously present in the same anatomic location(s), such as the same lymph node or lymph node region(s), the same organ(s), and/or the same tissue(s). The histology is coded to 9680/3 per PH11which states to code histology to diffuse large B-cell lymphoma (DLBCL) (9680/3) when DLBCL and any other non-Hodgkin lymphoma are present in the same lymph node(s), lymph node region(s), organ(s), tissue(s) or bone marrow.

20110019 Multiple primaries--Heme & Lymphoid Neoplasms: How many primaries are to be abstracted when bilateral testes are involved with lymphoma?

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

This is a single primary per Rule M2 which indicates to abstract a single primary when there is a single histology. Code the histology to 9590/3 [lymphoma] and the primary site to C629 [testes. Unless your software has edits that prevent coding laterality for lymphomas, code the laterality as bilateral. Up to half of extranodal lymphomas occur in multiple sites, particularly in paired sites.

20110006 Reportability--Heme & Lymphoid Neoplasms: Are all stages of CLL reportable? See Discussion. If a physician notes the patient has Stage 0 CLL (increasing leukocytosis), is this reportable? CLL Stage is not mentioned in the Hematopoietic Manual or Database, but internet research reveals CLL has five stages (Stage 0, I, II, III, and IV).

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

Yes. All stages of CLL are reportable. CLL has a unique staging system. The Heme DB and Manual do not address the issue of stage. Therefore, stage information is not reported in the Abstractor Notes section of the Heme DB.

20110039 Multiple primaries/Primary site--Heme & Lymphoid Neoplasms: What are the primary sites and how many primaries are abstracted, when 2004 diagnosis of grade 2 follicular lymphoma of the bilateral breasts is subsequently diagnosed with a 2010 diagnosis of diffuse large B-cell lymphoma (40%) and grade 3a follicular lymphoma (60%) of a left arm nodule? See Discussion.

Follicular lymphoma was diagnosed 7/2004, grade 2 per biopsy of the bilateral breasts. Bone marrow biopsy was positive for lymphoma involving 10% of bone marrow. Imaging showed extensive lymphadenopathy mainly in abdomen/pelvis with an 8 cm mass in the right pelvis. Smaller lymph nodes were noted in the left periaortic region and also some small precarinal lymph nodes. This was a stage IVA lymphoma. The patient had six cycles of CHOP/R with an excellent response. Per the clinician's notes on 12/2005, there was no evidence of recurrence or no sign of active disease. The plan was to follow up with the patient in 6 months.

08/22/06 imaging showed new disease in the bilateral chest wall. 8/2006 bilateral breast nodule biopsies, are positive for grade 1-2 follicular lymphoma. The patient was treated with Rituxan. Per clinician's 3/2007 note, no active disease is noted. Patient was regularly followed with no evidence of disease until 10/2010. At that time, the patient had a left arm nodule biopsy which was positive for diffuse large B cell lymphoma (40%) CD positive and grade 3a follicular lymphoma (60%). RICE was recommended due to "transformation" per oncologist.

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

Per Rule M10, this case should be accessioned as two primaries when a neoplasm is originally diagnosed as a chronic neoplasm (is follicular lymphoma (FL), grade 2) AND there is a second diagnosis of an acute neoplasm (diffuse large B-cell lymphoma) more than 21 days after the chronic diagnosis.

Code the histology for the first primary to 9691/3 [follicular lymphoma (FL), grade 2] and the primary site to bilateral C509 [breast, NOS]. FL can start as an extranodal disease; breast is one of the sites in which it originates. It is unlikely that the lymphoma extended from the nodes to the breast, but highly likely that it extended from the breast to the nodes.

Per Rule M4, abstract the 2010 disease process as a single primary when two or more types of non-Hodgkin lymphoma are simultaneously present in the same anatomic location(s), such as the same lymph node or lymph node region(s), the same organ(s), and/or the same tissue(s). Per Rule PH11 the primary site is coded to C779 [lymph nodes, NOS] and the histology is coded to 9680/3 [diffuse large B-cell lymphoma (DLBCL)]. Rule PH11 states one is to code the primary site to the site of origin, lymph node(s), lymph node region(s), tissue(s) or organ(s) and histology to diffuse large B-cell lymphoma (DLBCL) (9680/3) when DLBCL and any other non-Hodgkin lymphoma are present in the same lymph node(s), lymph node region(s), organ(s), tissue(s) or bone marrow.

20110015 Primary site/Histology: Do the 4/1/09 changes in the ICD-O-3 Site/Type Validation table regarding the coding of primary site for intestinal type adenocarcinoma mean that the former valid site/histology combinations are now impossible and require review from a given diagnosis date forward? See Discussion.

Per the SEER Errata for ICD-O-3 Site/Type Validation List, April 1, 2009, adenocarcinoma, intestinal type, was removed as a valid site/histology combination for the following primary sites: C150-C155, C158-C159, C170-C173, C178-C179, C180-C189, C199, C209, C210-C212, C218.

  • Does this mean that these combinations cannot be used? If so, then why is an override allowed for these site/type combinations? Shouldn't these site/type combinations be added to the impossible site/type combinations table?

  • SINQ 20081085 states that "8144/3 will be removed from the valid site/histology list for large intestine, small intestine, and rectum." It appears from the Site/Type Validation table that a decision was made to also remove esophagus sites as a valid combination with histology code of 8144. Please explain the rationale.

  • Cases that were miscoded to 8144/3 will need to be identified for correction. What date of diagnosis should be the reference point used in making the necessary corrections related to this change? Do we only need to review cases diagnosed 1/1/2009 forward or should all cases be corrected regardless of date of diagnosis?

    • The site/type edit identifies unlikely combinations of primary site and histologic type.

  • Intestinal type adenocarcinoma occurs in the stomach. It would be rare in another primary site, but not impossible.

  • It was decided that all digestive organ sites, except stomach, would be removed from the list. That is why esophagus is not listed as a valid site.

  • The site/type edit is for all years. Cases for all years have to be reviewed for combinations of site and type that are no longer on the list. If it is documented in the medical record that the primary site and histology combination are valid, set the over-ride flag so that the case will not come up for review again.

    		20110060 Reportability--Heme & Lymphoid Neoplasms: In the absence of any additional information regarding the disease process, is a diagnosis of "polycythemia" reportable if a patient is treated with phlebotomy?

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

    No. Polycythemia, NOS is not reportable.

    Polycythemia (also known as polycythaemia or erythrocytosis) is a disease state in which the proportion of blood volume that is occupied by red blood cells increases. Blood volume proportions can be measured as hematocrit level. It can be due to an increase in the mass of red blood cells, "absolute polycythemia"; or to a decrease in the volume of plasma, "relative polycythemia".

    The phlebotomy is a treatment for the excessive blood volume; therefore, a diagnosis of "polycythemia" without one of the modifying terms listed in the Heme DB under Alternative Names is not reportable.

    		20110058 Date of diagnosis/Flag: Will the Date of Diagnosis Flag ever be used if the instructions for coding Date of Diagnosis are followed? See Discussion.

    If an abstractor follows the instructions for coding the Date of Diagnosis and can at least estimate a year of diagnosis, in what scenario will the Flag be used?

    Per the 2010 SEER Manual,

    Page 49 Date of Diagnosis, second paragraph, "Regardless of the format, at least Year of diagnosis must be known or estimated. Year of diagnosis cannot be blank or unknown." The manual gives the following guidelines for coding diagnosis date/flag:

    Page 50, Coding Instructions:

    3. If no information about the date of diagnosis is available

    a. Use the date of admission as the date of diagnosis

    b. In the absence of an admission date, code the date of first treatment as the date of diagnosis.

    Page 51, Coding Instructions:

    9. Estimate the date of diagnosis if an exact date is not available. Use all information available to calculate the month and year of diagnosis.

    Page 53, Date of Diagnosis Flag, Coding Instructions:

    Always leave blank. Date of Diagnosis will always be a full or partial date recorded.

    		 The date of diagnosis flag should always be blank. 2011

    Reportability--Heme & Lymphoid Neoplasms: Is "common variable immunodeficiency" which is also known as acquired hypogammaglobulinemia reportable?

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

    Common variable immunodeficiency (acquired hypogammaglobulinemia) is not a reportable condition.

    Common variable immunodeficiency represents a group of approximately 150 primary immunodeficiencies that have a common set of symptoms but different underlying causes, both benign and malignant.

    The case is not reportable unless this immunodeficiency diagnosis is accompanied by a diagnosis of a cancer or a reportable hematopoietic or lymphoid neoplasm.

    See Appendix F: Non-Reportable List for Hematopoietic Diseases.
