20170058 | MP/H Rules/Histology--Lung: What is the correct histology code for an initial biopsy of non-small cell carcinoma with neuroendocrine phenotype, possible large cell neuroendocrine carcinoma with a subsequent re-biopsy showing poorly differentiated small cell carcinoma after chemotherapy with no response? See discussion. |
Patient had a biopsy in April 2014; pathology was reported as non-small cell carcinoma with neuroendocrine phenotype, possible large cell neuroendocrine carcinoma. The patient had five cycles of cisplatin/etoposide with no response. In May 2015, a re-biopsy at a referral institution reports poorly differentiated small cell carcinoma and states "feels that this could have been the histology all along and why patient has failed multi lines of chemo." |
Code to 8041, small cell carcinoma, because the medical opinon confirms that this was the correct histology from the begining. "Possible" is not an ambiguous term used to code histology. The MP/H rules do not include coding phenotype. That leaves non-small cell (8046/3) at time of diagnosis. Chemotherapy does not alter cell type so its likely the tumor was small cell all along only now proven with additional testing. Page 14 of the SEER Coding Manual gives examples of when to change the abstract's original codes and here is one example: When better information is available later. Example 1: Consults from specialty labs, pathology report addendums or comments or other information have been added to the chart. Reports done during the diagnostic workup and placed on the chart after the registrar abstracted the information may contain valuable information. Whenever these later reports give better information about the histology, grade of tumor, primary site, etc., change the codes to reflect the better information. |

20170050 | First course of treatment/Other therapy--How do you code medical marijuana when given as "treatment?" See Discussion. |
The patient has gastric cancer and the physician prescribed medical marijuana as treatment. SEER*Rx says marijuana is ancillary as a psychoactive cannabinoid and antiemetic and advises not to code it. The physician specifically wrote "treatment with" in the record. Should it be coded as Other (Code 1) under Other Therapy? |
Do not code as treatment. Enter the information regarding the use of marijuana in a text field. There have been some early clinical trials of cannabinoids in treating cancer in humans and more studies are planned. While the studies so far have shown that cannabinoids can be safe in treating cancer, they do not show that they help control or cure the disease. At this time, marijuana is used to treat side-effects (such as nausea, vomiting, and pain) and to help increase appetite which helps patients tolerate standard therapies. |

20170071 | Reportability/Brain and CNS: Is incidentaloma reportable from brain and central nervous system (CNS) imaging? See Discussion. |
We are seeing the term "incidentaloma" on magnetic resonance imaging (MR) reports of head and also with physician statements. For example, this MR of the head: Impression--Suboptimal study due to motion degradation. Heterogeneously enhancing pituitary gland without evidence of acute abnormality. A 3 mm focus of relative hypoenhancement in the left gland is favored to represent an incidentaloma. Advise correlation with clinical findings. Also, there are cases where the scans show meningioma and then at a later date it is stated to be an incidentaloma in physician notes. Is the term "incidentaloma" alone reportable, if the term "tumor" for CNS cases is never stated? When I googled the term, it is stated to mean "tumor." |
The term "incidentaloma" alone is not reportable. Look for a reportable term elsewhere or in later information. When the term "incidentaloma" is used on a magnetic resonance imaging (MR) report, it refers to "a disease or physical condition found as a secondary by-product of capturing the necessary volume of tissue within the field of view of the MR examination" (http://radsource.us/incidentaloma). It is not necessarily neoplastic. |

20170054 | MP/H Rules/Multiple primaries--Brain and CNS: How many primaries should be abstracted for a patient with a 2011 diagnosis of oligodendroglioma followed by biopsy of tumor which demonstrated progression in 2016 with pathology report Final Diagnosis indicating WHO grade III anaplastic astrocytoma? See Discussion. |
The clinical documentation clearly identifies residual tumor after the 2011 craniotomy. Scans demonstrated slow enlargement of the tumor over the years, which resulted in a repeat craniotomy. The pathologist noted in the diagnosis comment section of the pathology report that Is this a single primary per MP/H Rule M3 (A single tumor is always a single primary), or an additional brain malignancy per MP/H Rule M8 (Tumors with ICD-O-3 histology codes on different branches in Chart 1 or Chart 2 are multiple primaries)? |
Based on the information provided, this is a single primary. The 2011 tumor was not completely removed and progressed over the years. MP/H Rule M3 for malignant brain cancer applies. Do not change the original histology code. Use text fields to document the later histologic type of anaplastic astrocytoma, WHO grade III. |

20170007 | MP/H Rules/Histology--Urinary System: How should histology be coded when there are multiple bladder, ureter and renal pelvis urothelial tumors including non-invasive papillary urothelial carcinoma in the left ureter, invasive papillary urothelial carcinoma invading the lamina propria in the bladder, and an invasive sarcomatoid urothelial carcinoma of the renal pelvis that invades the muscularis? See Discussion. |
Per Rule M8, this is a single primary as there are multiple urothelial tumors as outlined in Table 1 (papillary urothelial carcinoma [8130] and sarcomatoid urothelial carcinoma [8122]) simultaneously present in multiple urinary organs (bladder, ureter and renal pelvis). As Rule M8 indicates these are a single primary, despite the histologies differing at the third digit (8130 vs 8122), then Rule H14 (Code the histology of the most invasive tumor) seems to be the most applicable histology rule. Following Rule H14 (in the Text version of the MP/H Rules), the histology would be coded as 8122 (sarcomatoid urothelial carcinoma) since the renal pelvis tumor was the most invasive tumor present. However, in both the Matrix and Flowchart versions of the MP/H Rules, Rule H14 contains a note (missing from the Text version) that states that this rule should only be used when the first three numbers of the histology codes are identical (This is a single primary). Rule M8 clearly tells us these are a single primary, despite the differences at the third digit of the histology. Further defaulting to Rule H15 (Code the numerically higher histology code) in this case would ignore the histology of the tumor with the worse prognosis (the most invasive tumor). Was this note included in the Matrix and Flowchart versions in error? |
Code the histology as 8122 according to the MP/H rules for Renal Pelvis, Ureter, Bladder, and Other Urinary, M8 and H14. Rule M8 states urothelial tumors in two or more of urinary sites including bladder and renal pelvis are a single primary. Rule H14 states code the histology of the most invasive tumors for multiple tumors abstracted as a single primary. |

20170043 | Reportability--Ovary: Is ovarian mucinous borderline tumor of intestinal type with microinvasion reportable? If reportable, what is the histology? See Discussion. |
4/18/17 Right ovary and fallopian tube, salpingo-oophorectomy: mucinous borderline tumor of intestinal type with microinvasion; greatest dimension 24.5 cm. Left fallopian tube and ovary, salpingo-oophorectomy: Benign ovary with multiple benign Mullerian inclusions. Benign fallopian tube with multiple paratubal cysts. Per pathology: pT1a pNx. |
For an ovarian mucinous borderline tumor, the term "microinvasion" is not an indication of malignancy according to the WHO classification of tumors, and our expert pathologist consultant agrees. Therefore, borderline mucinous ovarian tumor with microinvasion is not reportable. Low malignant potential/borderline ovarian tumors are defined by the pathology of the primary tumor in the ovary, and microinvasion there, or invasion in implants does not change that diagnosis. The only exception is when the lymph nodes are positive for malignancy, the case is reportable. If the lymph nodes are positive for mucinous borderline tumor, the case is not reportable. |

20170074 | Reportability--Kidney: Is a renal cell neoplasm stated to be multilocular clear cell renal cell neoplasm of low malignant potential a reportable tumor if the physician refers to the tumor as renal cell carcinoma in a follow-up note after surgery? If reportable, how is histology coded? See Discussion. |
The partial nephrectomy final diagnosis is renal cell neoplasm. The College of American Pathologists (CAP) Summary lists histology as: multilocular clear cell neoplasm of low malignant potential. The diagnosis comment adds: This neoplasm currently termed multilocular clear cell renal cell neoplasm of low malignant potential (WHO 2016), was previously termed cystic renal cell carcinoma. |
For now, report the case and code to 8310/3. In the 3rd Ed WHO Tumors of the Urinary System, multilocular clear cell RCC is coded as 8310/3, however the recent 4th Ed WHO Tumors of Urinary System notes this term is obsolete and a synonym for multilocular cystic renal neoplasm of low malignant potential (8316/1) which would be non-reportable. Per WHO 3rd Ed these tumors never recur or metastasize which may be why the behavior code is shown as /1. The standard setters must review this terminology change in relation to reporting the case as it may impact incidence rates. |

20170029 | Reportability--Bone: Are giant cell tumors (GCT) of the bone that metastasize to the lung reportable? See Discussion. |
Patient had radical resection of pelvic giant cell tumor of bone in August 2012. Final diagnosis clarified that no features to suggest a frankly malignant giant cell tumor were identified. July 2013 left upper lobe nodules were removed and found to be consistent with multifocal metastatic lung involvement with a previous pelvic giant cell tumor of bone. However, the pathology report comment specifies there are no histological high-grade features to suggest a malignancy: While SINQ 20091087 may apply, these metastases clearly arrived in the lung by hematogenous spread. The previous SINQ note refers to a case where the implants/metastases can seed the surrounding pelvic and abdominal structures by rupture of the tumor or intraoperative tumor spillage. That type of spread is not quite the same as the current case showing tumor cells leaving the primary tumor/site and travelling through the blood to implant in the lungs. |
This case is not reportable. According to the WHO Classification of Bone Tumors, pulmonary metastases from GCTs are "very slow-growing and are thought to represent pulmonary implants that result from embolization of intravascular growths of GCT. Some of these benign pulmonary implants can regress spontaneously. A small number, however, exhibit progressive enlargement and can lead to the death of the patient." The pathologist for this case is very clear that no malignancy was found in the lung or in the bone. |
