20150041 | MP/H Rules/Multiple primaries--Breast: Does rule M10 apply in this situation?
L breast biopsy = INVASIVE DUCTAL CARCINOMA
L breast simple mastectomy = 2.0 cm INVASIVE DUCTAL CARCINOMA with an incidental finding of separate 1.0 cm INVASIVE LOBULAR CARCINOMA; pathologist specifically states the tumors are morphologically different. The tumors are both pure Ductal/pure Lobular. |
Yes, Breast rule M10 applies. This case is a single primary.
Follow the MP/H rules even though the "pathologist specifically states the tumors are morphologically different" so that situations like this are reported consistenty accross cancer registries, regions, and states for consistent national reporting. |

20150023 | MP/H Rules/Histology--Thyroid: When is 8341/3, papillary microcarcinoma coded? The code description in ICD-O-3 is followed by (C739), yet there are two SINQ answers that tell us specifically to not use this code for thyroid primaries. Even the first revision of ICD-O-3 still carries the (C739) as part of this code, which goes against SINQ 20110027 and 20081127. |
Per the WHO Tumors of Endocrine Organs, for thyroid primaries/cancer only, the term micropapillary does not refer to a specific histologic type. It means that the papillary portion of the tumor is minimal or occult (1cm or less in diameter) and was found incidentally. WHO does not recognize the code 8341 and classifies papillary microcarcinoma of the thyroid as a variant of papillary thyroid and thereby should be coded to 8260. If the primary is thyroid and the pathology states papillary microcarcinoma or micropapillary carcinoma, code 8260 is correct. This information will be included in the upcoming revisions to the MP/H manual. |

20150024 | Surgery of Primary Site--Breast: How should the Surgery of Primary Site field be coded when a patient has a lumpectomy and an additional margin excision during the same procedure? See discussion. |
Operative report indicates a wire localized lumpectomy was performed. The pathology report includes a final diagnosis for two specimens as follows: A) LEFT BREAST, EXCISION: INFILTRATING DUCTAL CARCINOMA B) LEFT BREAST, NEW DEEP MARGIN, EXCISION: BENIGN BREAST TISSUES AND BENIGN FIBROFATTY SOFT TISSUES; NO EVIDENCE OF NEOPLASIA. The definition for Breast surgery code 23 is "Reexcision of the biopsy site for gross or microscopic residual disease". There is no indication whether the re-excision has to be a separate procedure or can be during the same procedure as the excisional biopsy (lumpectomy). Some hospital registrars in our region believe code 22 is more appropriate. |
Revised Answer Assign code 22 when a patient has a lumpectomy and an additional margin excision during the same procedure. According to the CoC, "Re-excision of the margins intraoperatively during same surgical event does not require additional resources; it is still 22. Subsequent re-excision of lumpectomy margins during separate surgical event requires additional resources: anesthesia, op room, and surgical staff; it qualifies for code 23." |

20150029 | First course treatment/Hormone Therapy--Lung: How is this field coded when the patient receives Prednisone for a metastatic lung adenocarcinoma? See Discussion. |
The SEER*Rx Database, Prednisone Primary Site indicates "Prednisone is used to treat multiple sites and histologies." The Remarks information states, "Prednisone may be coded as treatment (hormonal) for all sites and histologies. It is most often used as part of a drug regimen." While it is clear that Prednisone is coded as hormone therapy when administered as part of a drug regimen like CHOP, how is Prednisone coded when given outside of a drug regimen? Also, how is Prednisone coded for cancer-directed treatment of a metastatic lung primary? The NCI's PDQ does not list hormone therapy as cancer-directed treatment for a Stage IV lung adenocarcinoma.
In our specific case, Prednisone was started just after diagnosis, and before the completion of work-up proving distant metastasis. Often, Prednisone (or another hormone agent) is given as an ancillary treatment for the symptoms associated with the malignancy, and not as cancer-directed treatment.
|
Do not code Prednisone when it is given for symptoms. In most cases when Prednisone is given by iteself, not as part of a drug regimen, it does not affect the cancer and would not be coded as treatment. |

20150008 | Reportability--Heme & Lymphoid Neoplasms: Is idiopathic hypereosinophilia reportable? Must the diagnosis include the word 'syndrome'? |
Idiopathic hypereosinophilia is not reportable.
Hypereosinophilic syndrome is a different entity and is a synonym for chronic eosinophilic leukemia. |

20150007 | MP/H Rules/Histology: What is the proper histology code -- mucin producing adenocarcinoma or cholangiocarcinoma for the following case? See discussion. |
4/10/13 Partial hepatectomy: well differentiated mucin producing adenoca involve right and left hepatic ducts, common hepatic duct & common bile duct. Invasion beyond wall of bile duct. CT Scan after 1st surgery shows residual neoplasm cannot be excluded
7/31/13 Left lateral segmentectomy: residual well differentiated cholangiiocarcinoma involving connective tissue surrounding major bile ducts. Per medical director, histolgically code to cholangiocarcinoma.
Primary site: Extra hepatic bile duct. Chemo (5FU, Leucovorin, Oxaliplatin) was started 5/1.
|
Code the histology as well differentiated mucin producing adenoca based on the 4/10/13 pathology report.
Code histology from the pathology report of the procedure which removed the most tumor tissue -- this is from the MP/H general instructions for coding histology. We are assuming that the partial hepatectomy removed the most tumor tissue in this case.
Per WHO, mucin producing adenoca is a variant of cholangiocarcioma. |

20150043 | Seq no-central--Brain and CNS: How should subsequent tumors be sequenced when the patient has a history of a brain tumor, with no information on the behavior of the brain tumor? According to the sequencing rules, it appears some assumption must be made regarding the behavior of the brain tumor. |
Sequence the brain tumor in the 60-87 series when you do not know the behavior. If you have reason to believe the brain tumor was malignant, sequence it in the 00-59 series. |

20150066 | Grade--Breast: Do you take grade from the most representative specimen along with the histology? What is the correct histology/grade combination? See discussion.
|
Breast biopsy (from hospital A): DCIS, solid, cribriform, comedo type, high nuclear grade
Breast Lumpectomy (from hospital B): DCIS, cribriform type, nuclear grade 1, tumor 2.5cm |
Assign 8201/2 for this case.
MP/H rules are to code histology based on the specimen with the most tumor tissue. That would be the lumpectomy in this case. The histology is DCIS, cribriform type.
Reference: http://seer.cancer.gov/tools/mphrules/mphrules_instructions.pdf
The general rule for grade is to code the highest grade specified within the applicable grading system. For the case information provided, follow instruction #5, nuclear grade: use Coding for Solid Tumors #7: 2-, 3-, or 4- grade system. High nuclear grade (grade code 3 for breast) is higher than nuclear grade 1 (grade code 1).

20150018 | First course of treatment--Immunotherapy: Should Rituxan be coded to immunotherapy? See discussion. |
Is the instruction under #4.b. on page 114 of the 2014 SEER Program Coding and Staging Manual incorrect? It says to code Rituxan as chemotherapy. |
Rituxan changed categories from chemotherapy to a biologic therapy/Immunotherapy agent effective with cases diagnosed January 1, 2013. See page 150 or page 164 in the 2015 SEER manual. The instruction in the 2014 SEER manual was incorrect regarding Rituxan. |

20150030 | First course treatment--Surgical rocedure of other sites: How is this field coded when the patient undergoes a lung wedge resection for a pulmonary nodule that was never definitively or was ambiguously stated to be a metastasis? See Discussion. |
The patient was diagnosed with a carcinoid tumor of the small intestine. The pre-surgical work-up also identified a lung nodule that showed no octreotide uptake, but was indeterminate on biopsy. The imaging differential diagnosis included carcinoid, hamartoma, or a non-calcified granuloma. The patient underwent a resection of the primary small bowel tumor, and the physician noted the lung nodule was of unclear diagnosis. The physician stated a solitary lung metastasis would be atypical, but that lung metastatic involvement could not be ruled out. The physician recommended resection of the lung nodule to ensure that the patient was disease free. The lung wedge resection proved a pulmonary hamartoma.
The rules for coding Surgical Procedure of Other Site are not entirely clear. The definitions for First Course of Therapy in the SEER Manual do state that treatment includes, "Procedures that destroy or modify primary (primary site) or secondary (metastatic) cancer tissue." This would seem to exclude the lung resection as it did not destroy, modify or remove metastatic cancer tissue. However, the instructions for coding Surgical Procedure of Other Site do not address removal of distant sites that are not incidental. The lung resection was not incidental; the physician recommended it to ensure the lung was not involved, but it also disproved metastatic involvement. Should the Surgical Procedure of Other Site field be coded 0 (none) or 4 (non-primary surgical procedure to distant site) in this case?
|
Code 0 for Surgical Procedure of Other Site in this case. The Surgical Procedure of Other Site field is used to capture surgery to destroy or modify cancer tissue that is not captured in other surgery fields. |
