20100087 | Multiple primaries--Heme & Lymphoid Neoplasms: How many primaries are accessioned for one patient with history of marginal zone lymphoma initially diagnosed in 1994, followed by a 2010 diagnosis of large B-cell lymphoma and another patient with both B-cell chronic lymphocytic leukemia/small cell lymphoma (CLL/SLL) and diffuse large B-cell (DLBCL) in 2009? See Discussion. | Case 1 - Patient has a history of marginal zone lymphoma diagnosed in 1994 with recurrences in 2007 and 2009. The patient now presents for a bone marrow biopsy in May 2010 and is found to have large B-cell lymphoma, transformation. The first primary, marginal zone lymphoma, falls under the 2009 rules and the second primary, large B-cell lymphoma, falls under the 2010 and forward rules?
Case 2 - Patient was diagnosed with B-cell CLL/SLL and a DLBCL in 2009. If the 2009 rules only apply, these are a single primary. If the patient is admitted and treated in 2010 are the rules still based on the diagnosis date? |
For cases diagnosed 2010 and forward, access the Hematopoietic Database at http://seer.cancer.gov/seertools/hemelymph.
Case 1: Accession two primaries per Rule M10 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 histology for the first primary is 9699/3 [marginal zone lymphoma] represents a chronic neoplasm and the second primary is 9680/3 [diffuse large B-cell lymphoma] is an acute neoplasm which was diagnosed more than 21 days after the first primary.
Case 2: Do not use the Heme DB and Manual rules for this case. Both diagnoses were made prior to 2010. The Heme DB and Manual are only effective for cases diagnosed 1/1/2010 and forward. Use the ICD-O-3 Hematopoietic Primaries Table to determine the number of primaries for this case. Per the Table, a second diagnosis of DLBCL [9680/3] following a diagnosis of CLL/SLL [9823/3] is one primary.

20100054 | MP/H Rules/Multiple primaries--Breast: How many primaries are accessioned if a pathology specimen reveals an infiltrating mammary carcinoma with mixed tubular and lobular features, 2.3 cm, low grade cribriform in situ ductal carcinoma, and Paget disease of the overlying skin with ulceration? See Discussion. | According to SINQ 20081134 the histology would be 8524 if this is one primary. | For cases diagnosed 2007 or later, this is a single primary.
In order to determine whether this case represents a single or multiple primary, you must first determine the correct histology code for the underlying tumor. Using rule H9, ignore the DCIS.
See Table 3 in the equivalent terms and definitions. Infiltrating lobular, tubular, and Paget are coded to a single histology code (8524/3). Our current multiple primary rules do not say infiltrating lobular and tubular and Paget are a single primary. This was an omission and will be corrected in a future revision. Thank you for bringing this omission to our attention. |

20100105 | Surgery of Primary Site--Brain and CNS: Is "debulking" of a primary brain tumor coded to 21 [subtotal resection of tumor] or 30 [gross resection of tumor]? | Assign code 21 [subtotal resection of tumor, lesion, or mass]. Debulking removes as much of the tumor volume as possible in cases where it is not possible to remove the entire tumor. Debulking should improve the effectiveness of subsequent radiation therapy and/or chemotherapy. | 2010 | |
|
20100104 | Grade--Heme & Lymphoid Neoplasms: Is the phrase "aberrant T-cell expression" enough to code the grade field to T-cell when the final diagnosis on the pathology report is "AML with aberrant T-cell antigen expression"? | Yes. Code grade to 5 [T-cell]. The T cell receptor, or TCR, is a molecule found on the surface of T lymphocytes (or T cells). | 2010 | |
|
20100036 | Behavior--Lung: Can an in situ behavior code be used for a bronchioalveolar carcinoma of the lung when the pathologist appears to use the term bronchioalveolar to describe an in situ pattern of growth exhibited by an adenocarcinoma? Is the use of the term "pattern" in this situation indicative of in situ tumor? See Discussion. | In ICD-O-3, bronchioloalveolar adenocarcinoma is described only by behavior code 3 (invasive). Would the behavior be coded as in situ for the following cases?
Example 1: Left lower lobe, partial resection shows bronchioloalveolar carcinoma with focal areas of fibrosis (see comment). Comment: Although the possibility that these areas represent stromal invasion can not be excluded, we favor the interpretation that these areas do not represent true invasion. Synoptic summary: Minimal pathologic stage: Local Extent.
Example 2: Lung tumor described as adenocarcinoma, predominantly bronchoalveolar pattern. For most sites, the term pattern is used only for in situ cancer and is not a specific term used for invasive tumors. Is the use of the term "pattern" in this situation indicative of in situ tumor? |
Code the behavior indicated in the pathology report. If the pathologist states the bronchioloalveolar carcinoma is in situ, apply the ICD-O-3 matrix rule and assign 8250/2. Otherwise, code 8250/3. Do not use the term "pattern" to infer in situ behavior.
Code behavior /3 for both examples based on information provided. |

20100064 | Histology--Heme & Lymphoid Neoplasms: How is histology to be coded for acute lymphoblastic leukemia (ALL) and/or precursor B acute lymphoblastic leukemia (Pre-B ALL) for cases diagnosed 2010 and later? The Heme Database has two histology codes for this disease, both 9811/3 and 9836/3, which is the correct histology code? |
For cases diagnosed 2010 and forward, access the Hematopoietic Database at http://seer.cancer.gov/seertools/hemelymph.
Code histology to 9811/3 [B lymphoblastic leukemia/lymphoma, NOS].
See the Abstractor Notes section in the Heme DB, when determining how to code histology for a case. It indicates the code 9811/3 is effective for cases diagnosed 2010 and forward. The 9836/3 is listed as obsolete and refers you to code 9811/3. Make sure to check for a specific subtype of B lymphoblastic leukemia/lymphoma [9812/3 - 9818/3] before assigning the NOS code [9811/3].

20100010 | MP/H Rules/Multiple primaries--Ovary: How many primaries are to be abstracted when a patient is diagnosed with serous cystadenocarcinoma [8441] of the right ovary and clear cell adenocarcinoma [8310] of the left ovary? See Discussion. |
Patient had bilateral ovarian tumors. The right ovary had serous cystadenocarcinoma and left ovary had clear cell adenocarcinoma. The pathology COMMENT section stated, "Based on the histologic differences of the tumors within each ovary, feel these represent two distinct separate primaries. Lymph node metastases are clearly serous ca." The physician staged the right ovary as T2a N1 M0 and left ovary as T1c N0 M0. Do we accession one primary per rule M7 [Bilateral epithelial tumors (8000-8799) of the ovary within 60 days are a single primary]? What is intention of Rule M7? If the histology in each ovary is different but within the range (8000-8799), is that supposed to be accessioned as one primary? Or is the intention of Rule M7 that tumors in both ovaries must have the SAME histology within that histology range to be a single primary? |
For cases diagnosed 2007 or later, apply rule M8 and abstract this case as multiple primaries. Rule M7 does not apply when each ovary has a distinctly different histology, even when both histologies are with the specified code range. This clarification will be added to the next version of the rules. |

20100074 | Laterality--Melanoma: For a melanoma case, does the term "mid" imply that the tumor is in the midline when the site is the skin of back (trunk)? | Yes. When the location is described as mid-back or mid-chest with no indication of left or right, assign laterality code 5 [midline]. | 2010 | |
|
20100066 | MP/H Rules/Multiple Primaries--Breast: How many primaries should be accessioned if two tumors are present in the same breast, a 1.7 cm colloid carcinoma and a 1.5 cm colloid carcinoma with infiltrating ductal carcinoma? See Discussion. | If a patient has two masses in the same breast with different histology codes and different sizes, should this be accessioned as two primaries? Or should this be a single primary based on the largest tumor size or numerically higher histology code?
|
For cases diagnosed 2007 or later, abstract this case as two primaries. Mucinous/colloid carcinoma of the breast is rare. The first tumor describes (1.7 cm) fits this criteria because the pathologist simply says mucinous carcinoma. The diagnostic criteria for mucinous carcinoma is that pools of extracellular mucin make up at least 1/3 of the volume throughout the tumor mass. If focal areas are not at least 33% mucinous, the designation is a mixed mucinous/ductal. That fits the second tumor (1.5 cm).
For this case, you must get the histology codes for both tumors in order to use the Multiple Primary rules. Per H14 the first tumor is coded mucinous carcinoma [8480/3]. Per H17 the second tumor is coded duct carcinoma mixed with any other carcinoma [8523/3]. Now go to the MP rules. Per M12 abstract this case as multiple primaries because the ICD-O-3 histology codes are different at the second and third digit. |

20100099 | Histology--Heme & Lymphoid Neoplasms: Should all cases of precursor B acute lymphoblastic leukemia diagnosed 1/1/10 and later with histology coded to 9836/3 have the values changed to 9811/3 per the Heme DB Abstractor Notes section or should they remain coded 9836/3. | For cases diagnosed 2010 and forward, access the Hematopoietic Database at http://seer.cancer.gov/seertools/hemelymph.
For cases diagnosed 2010 and forward, code histology to 9811/3 [B lymphoblastic leukemia/lymphoma, NOS] which is the new classification for pre-BALL. The histology code 9836/3 is obsolete as of 2010 and should not be used for cases with diagnosis date after 12/31/2009.
