20130216 | Primary site--Heme & Lymphoid Neoplasms: Need help determining primary site for Diffuse Large B-Cell Lymphoma 9680/3 confirmed pathologically in right ovary and soft tissue left adnexa. No lymph nodes examined pathologically. Patient treated outside and no access to notes. See discussion. |
CT A/P massively enlarged uterus with no distention between the vagina, cervix or proximal to mid uterus identified. Highly concerning for malignancy though distinct etiology not clear. Ovarian not favored though not excluded given lack of clearly defined fat planes between uterus and either ovary. Extensive bilateral iliac chain and periaortic/pericaval lymphadenopathy.
Trying to work through Module 7 in the Hem DB. According to the ovary site, regional lymph nodes include the iliac and the para-aortic lymph nodes. This makes me think I should use Rule PH35 (organ and regional nodes). However, using Appendix C in the Hem DB, the iliac lymph nodes are part of the pelvic C775 while the para-aortic (periaortic) are intra-abdominal C772. This makes me wonder if I should go with rule PH36 present in organ and nodes that are not regional. |
Use Rule PH25 and code primary site to C569.
First determine if the iliac and para-aortic lymph nodes are regional for Ovary. Use AJCC TNM or Collaborative Stage. Per AJCC 7th edition, regional lymph nodes for ovary include iliac and para-aortic (pg. 419). Therefore, this case involves an organ and its regional lymph nodes. Use appendix C to determine how to code a lymph node primary. It should not be used to determine whether lymph nodes are regional for a specific organ. |

20130124 | Reportability--Heme & Lymphoid Neoplasms: Is Rosai-Dorfman's syndrome (histiocytosis) a reportable malignant condition? | Rosai-Dorfman disease is not reportable. Rosai-Dorfman disease is a rare non-neoplastic disease. This disease can mimic lymphoma and extranodal involvement is frequent. | 2013 | |

20130010 | MP/H Rules/Histology--Skin: How is the histology coded for "infiltrative carcinoma with ductal alterations compatible with squamoid eccrine ductal carcinoma" of the skin? | Code the histology to 8413/3 [eccrine adenocarcinoma]. This is the most specific code available for this diagnosis.
According to our expert pathologist advisor, "The adnexal glands in the skin, sweat (eccrine) glands and apocrine glands, all have ducts which connect the business portion of each gland to the skin surface. Some of the adnexal tumors have features of differentiation which appear to be duct-like, hence the designation 'ductal.'"
In addition, "The 'squamoid' simply indicates some degree of squamous differentiation, but doesn't alter the usefulness of [code 8413/3] because we have no way of coding anything more specific in this case anyway." |

20130118 | Primary site--Heme & Lymphoid Neoplasms: How is the primary site coded for a diagnosis of Langerhans cell histiocytosis with extensive bony metastatic disease and lymphadenopathy? See Discussion. | Patient was diagnosed with LCH on a biopsy of the right femur. Imaging showed extensive bony metastatic disease, extensive infiltrative perinephritis, encasement of both kidneys, renal hilar, retroperitoneal and periaortic lymphadenopathy. The right femur biopsy pathology report did not state this was metastatic. | For cases diagnosed 2010 and forward, access the Hematopoietic Database at http://seer.cancer.gov/seertools/hemelymph.
Code the primary site to C419 [bone, NOS] per Rule PH30.
This patient has widely metastatic disease. Per Rule PH30, one needs to reference the Heme DB to determine the primary site and histology for this case. Per the Abstractor Notes section, Langerhans cell histiocytosis arises in the bone and many times can involve multiple bones, along with other organs and lymph nodes. Although the right femur was biopsied, this does not prove that the primary site is the femur [C402] because the patient has what was described as extensive bony metastatic disease.

20130040 | Multiple primaries--Heme & Lymphoid Neoplasms: How many primaries are accessioned and what rule applies when a patient has a history of chronic myeloid leukemia diagnosed in 1993 followed by a diagnosis of acute myeloid leukemia arising in chronic myelogenous leukemia, blast phase? See Discussion. |
12/1993 Bone marrow biopsy: Chronic myeloid leukemia t(9;22) (q34;q11).
09/2011 Bone marrow biopsy: Abnormal cytogenetic & FISH support persistent involvement by chronic myelogenous leukemia.
12/2011 Peripheral blood, flow cytometry: Involvement by acute myeloid leukemia arising in chronic myelogenous leukemia (CML, blast phase, 30% blasts by manual diff.).
Is the 12/2011 diagnosis a new primary? If not, why don't Rules M8-M13 apply when the Heme DB Abstractor Notes section for CML indicates that when there is a chronic, accelerated and blast phase that develops later in the course of the disease, change the histology code to the more specific diagnosis?
|
For cases diagnosed 2010 and forward, access the Hematopoietic Database at http://seer.cancer.gov/seertools/hemelymph.
This case should be accessioned as a multiple primary: chronic myelogenous leukemia t(9;22) (q34;q11) [9863/3] diagnosed in 1993 and acute myeloid leukemia [9861/3] diagnosed in 2011 per Rule M15.
Use the diagnosis date to determine the appropriate manual and rules to follow to determine the histologies for this case. To determine the histology of the 1993 diagnosis, use the ICD-O-2. The Heme Manual & DB will be used to determine the number of primaries and the histology of the 2011 diagnosis of AML.
Rules M8-M13 in the Heme Manual cannot be applied to this case because no transformation occurred. CML does not transform to another neoplasm.

20130089 | MP/H Rules/Histology--Breast: How is the histology coded when a pre-treatment core biopsy showed ductal carcinoma, but the mastectomy specimen following neoadjuvant chemotherapy showed lobular carcinoma? See Discussion. | 11/06/2012 Ultrasound-guided biopsy of the left breast and left axilla showed invasive ductal carcinoma. The patient underwent 6 months of chemotherapy. In 05/2013 the patient underwent a mastectomy that showed invasive lobular cancer, pleomorphic type, with 11 axillary lymph nodes negative. | The histology is coded to lobular carcinoma, NOS [8520/3] because the mastectomy (the most representative specimen) showed only lobular carcinoma.
The MP/H Rules state to code the histology from the most representative tumor specimen examined. Although this patient underwent neoadjuvant treatment, there is no indication that the ultrasound-guided biopsy contained more tumor than the mastectomy. The mastectomy is the most representative specimen and should be used to code the histology.

20130052 | Histology--Heme & Lymphoid Neoplasms: How is the histology coded if a biopsy final diagnosis is diffuse large B-cell lymphoma but the physician's final diagnosis favored anaplastic large cell lymphoma? See Discussion. | Patient has diffuse intrathoracic, intraabdominal and pelvic lymphadenopathy. An inguinal lymph node biopsy showed diffuse large B-cell lymphoma. The physician's final diagnosis favored anaplastic large cell lymphoma, but wanted to confirm this with FISH. The patient clinically deteriorated so the FISH studies were not done. Which histology is coded? | For cases diagnosed 2010 and forward, access the Hematopoietic Database at http://seer.cancer.gov/seertools/hemelymph.
The histology should be coded as diffuse large B-cell lymphoma [9680/3]. The biopsy pathology report definitively diagnosed DLBCL. The physician's diagnosis cannot be used because it is an ambiguous diagnosis only, "favored anaplastic large cell lymphoma." "Favor" is an ambiguous term.

20130012 | MP/H Rules/Multiple primaries--Urinary: If topography codes C681-C689 are not included in Urinary Multiple Primary Rule M8, would a subsequent renal pelvis papillary transitional cell carcinoma be a new primary? See Discussion. |
The patient had a papillary transitional cell carcinoma of the bladder and ureter diagnosed in 2010. The primary site was coded to C689 [urinary system, NOS]. The patient was diagnosed with a transitional cell carcinoma of the renal pelvis [C659] in 2012. In applying the MP/H rules to the 2012 diagnosis, rule M8 would be ignored because the primary site of the 2010 primary was coded to C689. The result is that M9 or M10 would be applied which indicates a new primary for the 2012 diagnosis. Should the 2012 renal pelvis carcinoma be a new primary? |
For cases diagnosed 2007 or later, accession a single primary, papillary transitional cell carcinoma of the bladder and ureter [C689, urinary system, NOS] diagnosed in 2010. The steps used to arrive at this decision are: Open the Multiple Primary and Histology Coding Rules Manual. Choose one of the three formats (i.e., flowchart, matrix or text). Go to the Urinary MP Rules because site specific rules exist for this primary. Start at the MULTIPLE TUMORS module, rule M3. The rules are intended to be reviewed in consecutive order within a module. This patient has urothelial tumors in two or more of the listed sites (bladder, ureter and renal pelvis) diagnosed within 3 years. When C689 is assigned because tumors of the bladder and tumors of the ureter were determined to be a single primary and the site of origin is not known (as in this example), rule M8 is applied when a subsequent tumor is diagnosed in one of the listed sites. However, if site C689 [urinary system, NOS] was assigned for other unknown urinary primary site situations, rule M8 would not be used. Rule M8 was written specifically for urothelial tumors in the renal pelvis, ureter, bladder and urethra. Paraurethral gland [C681] and overlapping lesions of urinary organs [C688] do not belong in rule M8. We will add this issue to the list of possible revisions for the next edition of the MP/H Rules. |

20130195 | Laterality--Heme & Lymphoid Neoplasms: Is laterality coded to 0 [not paired] for all lymphoma cases including paired sites (e.g., breast, lung)? | Laterality coding for lymphomas is based on the primary site not histology. Laterality describes the side of a paired organ or side of the body on which the reportable tumor originated. Determine whether laterality should be coded for each primary.
Laterality coding instructions are located in the SEER Program Coding and Staging Manual. See pages 68-70 in the 2013 manual, http://www.seer.cancer.gov/manuals/2013/SPCSM_2013_maindoc.pdf. |
