20120092 | MP/H Rules/Multiple primaries/Recurrence -- Lung: How many primaries are accessioned if a diagnosis of squamous cell carcinoma of the lung is followed three years later by a diagnosis of adenocarcinoma of the lung if the pathologist reviews all the slides and states the subsequent diagnosis is a recurrence? See Discussion. | 7/12/2007 Left upper lobe lung lobectomy: Squamous cell carcinoma.
3/09/2010 Left lung completion pneumonectomy: Adenocarcinoma, predominantly acinar. The diagnosis comment on the pathology report indicates the previous lobectomy specimen from 2007 was reviewed and "there are areas that appear histologically similar to the current neoplasm. Thus, the findings are most compatible with recurrence."
Despite the difference in histology, is this a single primary per the MP/H Coding Rules, General Information instruction 7 because the pathologist did refer to the 3/9/2010 diagnosis as a "recurrence" of the 7/12/2007 diagnosis after reviewing the slides? |
For cases diagnosed 2007 or later, accession a single primary, left upper lobe squamous cell carcinoma diagnosed 7/27/2007.
The steps used to arrive at this decision are:
Go to the General Information notes for Determining Multiple Primaries for Solid Malignant Tumors in the Multiple Primary and Histology Coding Rules Manual.
General Information Rule 7 states "Use the multiple primary rules as written unless a pathologist compares the present tumor to the "original" tumor and states that this tumor is a recurrence of cancer from the previous primary."
Accession a single primary. Do not apply the Multiple Primary rules because the pathologist compared the 2007 and 2010 slides and determined this was a recurrence and not a new primary. |

20120094 | Reportability: Given that per the 2012 SEER Manual and SINQ 20120081 VIN II-III is no longer reportable, does this change exclusively apply to VIN II-III or does it also apply to AIN II-III, VAIN II-III, etc.? See Discussion. |
VIN II-III was a reportable condition in the past. There was a SINQ note to that effect which is now gone from the system. Would it be better to reactivate that note and put a date reference in it so that there is documentation available to confirm this disease (and other IN II-III diseases) was previously reportable? If the note is not reactivated, could there be some indication in SINQ 20120081 of the prior reportability of this disease process? |
For cases diagnosed 2021 or later, VIN II-III is reportable. Similarly, AIN II-III, VAIN II-III, etc. are reportable. For cases diagnosed 2021 or later, the primary resource for reportability is ICD-O-3.2. Squamous intraepithelial neoplasia, grade II is listed in ICD-O-3.2 as 8077/2 making it reportable. This applies to the various sites of intraepithelial neoplasia grade II including anus, vulva, and vagina. |

20120065 | MP/H Rules/Primary site: What is the primary site and histology for a focus of papillary thyroid cancinoma, follicular variant, arising in thyroid tissue of mature cystic teratoma of the ovary? | For cases diagnosed 2007 or later, code the primary site to ovary [C56.9] and the histology to papillary carcinoma, follicular variant [8340/3].
The steps used to arrive at this decision are:
Refer to the 2012 SEER Manual for help to determine the primary site. This neoplasm is arising in a teratoma of the ovary. Per the 2012 SEER Manual, in this case the site is coded to ovary [56.9] because that is where the tumor originated. Although the teratoma contains thyroid tissue, it arose in the ovary. Teratomas are unusual in that they contain all three germ cell layers from which an embryo forms. It is not unusual to have malignancies that are usually primary to the thyroid, liver, brain, lung, etc., originate in a teratoma.
Open the Multiple Primary and Histology Coding Rules Manual. Choose one of the three formats (i.e., flowchart, matrix or text). Go to the Other Sites Histology rules because site specific rules have not been developed for this primary.
Start with the SINGLE TUMOR: INVASIVE ONLY module, rule H8. The rules are intended to be reviewed in consecutive order within a module. Code the histology as papillary carcinoma, follicular variant [8340/3]. |

20120009 | Histology--Heme & Lymphoid Neoplasms: How is the histology coded when the pathology report states the morphologic features and immunophenotype of a low grade B-cell lymphoma are most compatible with lymphoplasmacytic lymphoma or marginal zone lymphoma? | For cases diagnosed 2010 and forward, access the Hematopoietic Database at http://seer.cancer.gov/seertools/hemelymph.
Code the histology to 9591/3 [B-cell lymphoma, NOS] per Rule PH28 which states that one is to code the histology when the diagnosis is
There is only one non-specific histology code mentioned, low grade B-cell lymphoma. This term is synonymous with B-cell lymphoma, NOS.
Per the Multiple Primaries Calculator, when comparing the histology 9591/3 [B-cell lymphoma, NOS] and 9671/3 [lymphoplasmacytic lymphoma], it is the same primary. When comparing the histology 9591/3 [B-cell lymphoma, NOS] and 9699/3 [marginal zone lymphoma], it is the same primary.

20120016 | Reportability--Heme & Lymphoid Neoplasms: Is "amyloidosis" reportable if the medical oncologist states that it is a malignancy? See Discussion. |
Amyloidosis is not reportable per the Commission on Cancer guidelines. However, the medical oncologist at this facility states that it is a malignancy. The oncologist presented a case at Cancer Conference and indicated the patient has Stage III disease. Should this case be accessioned? |
For cases diagnosed 2010 and forward, access the Hematopoietic Database at http://seer.cancer.gov/seertools/hemelymph. Amyloidosis, NOS is not reportable. It is listed in Appendix F of the Heme Manual on the Non-Reportable List for Hematopoietic Diseases. Amyloidosis (AL) is term that refers to a group of conditions that include benign conditions (e.g., found in the pancreas of type II diabetes patients and in the brain lesions of Alzheimer patients) as well as in malignant diseases (e.g., AL found in multiple myeloma and ACal (calcitonin) found in medullary carcinoma of the thyroid). Amyliodosis, NOS is not a term that equates to a malignant diagnosis. Check the medical record to see if this disease process is designated as either AL or ACal. There should be a malignant diagnosis such as multiple myeloma or medullary carcinoma of the thyroid in such cases rather than simply a diagnosis of amyloidosis. The malignancy needs to be coded, not the symptoms of the disease process. SEER*Educate provides training on how to use the Heme Manual and DB.

20120060 | Primary Site/Reportability: What is the primary site and reportability status of a "pancreatic endocrine neoplasm" that arises in the heterotopic pancreas of the splenic hilum that is stated to be a "well-differentiated endocrine tumor, uncertain behavior per the WHO classification"? See Discussion. | SINQ 20120035 states that well differentiated pancreatic endocrine neoplasms should be reported with histology code 8240/3. However, the pathology report provides the WHO Classification which states "uncertain behavior." Should this tumor still be reported as 8240/3?
If reportable, how is the primary site coded? The tumor arose in heterotopic pancreas (in the splenic hilum), which is pancreatic tissue found outside the usual anatomical location of the pancreas. Per the pathology report, the tumor did not invade the spleen. Should the primary site be coded to C48.1 [mesentery]? The patient is female and the coding schema for "Peritoneum for Females" would apply to the case. However, none of those CS extension codes seem to apply to this localized case.
|
This case is reportable. Code the primary site to C25.9 [pancreas, NOS] and the histology to 8240/3 [neuroendocrine tumor (NET), Grade 1].
Per the 2012 SEER Manual, code the site in which the primary tumor originated. This neoplasm arose in pancreatic tissue and will behave accordingly, even though this pancreatic tissue is not located in the usual place.
Pancreatic endocrine and neuroendocrine neoplasms are essentially the same thing. However, they are described in two different WHO classifications; the endocrine classification and the digestive system classification. The digestive system classification is more recent, and is preferred by our expert pathologist consultant. The term "neuroendocrine" is to be used now, rather than "endocrine." In the pancreas, "well differentiated endocrine tumor" is synonymous with "neuroendocrine tumor (NET) Grade 1" and is coded 8240/3. |

20120085 | Reportability--Ovary: Are mature teratomas of the ovary reportable? See Discussion. |
Per a NAACCR Webinar from February 2011 (Testis), "All adult (post-puberty) pure mature teratoma tumors are malignant and should be coded 9080/3.' Does this apply to ovarian cases? The medical record entries all seem to indicate this a benign process. Should this NAACCR Webinar info be applied specifically to testicular cases? Would this be a reportable case if the primary site were testis? The patient also has a history of medullary carcinoma of the thyroid. SINQ 20100052 indicates a thyroid primary may present in an ovarian teratoma. Would this be reportable, or must there be mention of the histology other than, or in addition to, the mature teratoma? |
Mature teratomas in the ovary are benign [9080/0]. For testis, mature teratoma in an adult is malignant (9080/3); however, mature teratoma in a child is benign (9080/0). With regard to the thyroid issue, from the information above, the medullary carcinoma in the patient's thyroid is clearly a separate event. According to our expert pathologist consultant, "thyroid tissue is one of the many tissue types that may be seen in teratomas. When the teratoma has exclusively or predominantly thyroid tissue the term struma ovarii is used Adenoma or carcinoma of the thyroid type may be seen in this thyroid tissue. If medullary carcinoma were present in the thyroid tissue in the ovary/teratoma, there would be mention of it in the path report." |

20120055 | Surgery of Primary Site--Kidney, renal pelvis: How do you code a laparoscopic renal mass core biopsy followed by cryoablation of the tumor? See Discussion. | The note under the local tumor destruction codes states "No specimen sent to pathology from this surgical event 10-15." The patient had a pathologic specimen submitted from his core biopsy, but this was not a tumor excision or excisional biopsy [codes 20, 26-27]. Is the correct surgery code 13 [cryosurgery] because the tumor was only ablated and not excised, or surgery code 23 [any combination of 20 or 26-27 with cryosurgery] because a pathology specimen was submitted? | Code for Surgery of Primary Site to 13 [Cryosurgery]. While the core biopsy provided a pathology specimen, it is not coded as surgery of the primary site. | 2012 |

20120074 | Multiple primaries--Heme & Lymphoid Neoplasms: How many primaries are accessioned if a patient is diagnosed in 2004 with extranodal diffuse large B-cell lymphoma (DLBCL) of the stomach followed by a 2011 diagnosis of DLBCL involving abdominal lymph nodes? See Discussion. | In 2004 a patient's extranodal DLBCL was treated with a partial gastrectomy at another facility. A recurrence of DLBCL was diagnosed in 2011 by a fine needle aspiration of abdominal lymph nodes. The patient presented to this facility for chemotherapy. | For cases diagnosed 2010 and forward, access the Hematopoietic Database at http://seer.cancer.gov/seertools/hemelymph.
This case is accessioned as a single primary. Code the histology to 9680/3 [diffuse large B-cell lymphoma] and diagnosis date to 2004. Per Rule M2, abstract as a single primary when there is a single histology.

20120071 | Primary site--Heme & Lymphoid Neoplasms: How is the primary site coded and what rule applies if the patient has involvement of multiple organs and one lymph node chain with diffuse large B-cell lymphoma? See Discussion. |
In 2011 the patient was diagnosed with a 15 cm mass involving the terminal ileum, cecum and adjacent mesentery. The pathology was positive for diffuse large B-cell lymphoma. A staging PET/CT revealed a mass at the base of tongue and a left cervical lymph node. The biopsy of the base of tongue also showed DLBCL. |
For cases diagnosed 2010 and forward, access the Hematopoietic Database at http://seer.cancer.gov/seertools/hemelymph. Apply rule PH22 to code the primary site to C779 [lymph nodes, NOS]. While the pathology does not indicate that this particular case represents a B-cell lymphoma, unclassifiable with features intermediate between DLBCL and Burkitt variant, in the Abstractor Notes section of the Heme DB for diffuse large B-cell lymphoma it does indicate that its presentation, "may have lesions in ileocecal region or jaws. Bone marrow and peripheral blood may be involved. Patients present with lymphadenopathy or mass lesions in extranodal site." This patient does have involvement of two extranodal sites and involvement of regional lymph nodes for only one of those sites. PH22 indicates one is to code the primary site to C77.9 [lymph nodes, NOS] when lymphoma is present in multiple organs and lymph nodes that are not regional for that organ and the origin cannot be determined even after consulting the physician. There are two extranodal sites of involvement and only one chain of lymph nodes is regional to one of those sites so this rule applies.
