20160077 | First course treatment/Immunotherapy--Prostate: Is XGEVA, given for bone mets from prostate cancer, abstracted as immunotherapy, or is it an ancillary drug and not recorded? |
Do not record XGEVA when given for bone mets from prostate cancer. See SEER*Rx for more information.

20160032 | Reportability--Brain: Is benign lymphangioma of the brain (9170/0) reportable? It is not on the list of non-malignant blood vessel tumors in the National Program of Cancer Registries Clarifications for Central Nervous System (CNS) tumors. |
Lymphangioma of the brain or CNS is not reportable. Lymphangioma is a malformation of the lymphatic system. Even though it has an ICD-O-3 code, do not report it. |

20160017 | Surgery of Primary Site--Melanoma: Please further explain the SEER Note under Melanoma surgery codes 30-36 for these two examples. Are both examples coded 31? 1. Shave bx: +melanoma in situ, +microscopic margins Wide excision: no residual melanoma in situ 2. Shave bx: melanoma, +microscopic margin Wide excision: Melanoma, margins negative (margin status negative but distance not stated) |
Revised answer: Assign surgery code 30 for both examples based on the SEER Note on the top of page 2 in the Surgery of Primary Site Codes for Skin: If it is stated to be a wide excision or reexcision, but the margins are unknown, code to 30. |

"Thank you for sending this fascinating case. In reviewing the H&E-stained slides, we recognize that multiple lesions of varying sizes are present within the specimen, some with features of oncocytoma, some with those of chromophobe RCC, and yet others with features of both. The immunohistochemical studies for CK7 performed at your institution serve to highlight this point with "mass #1" showing focal single cell staining typical of oncocytoma and "mass #2" showing a patchy and confluent staining pattern typical of chromophobe RCC. This second mass was also positive with special stain for Hales colloidal iron. As mentioned, the morphology varies somewhat in each tumor, however, every single mass is comprised of cells with eosinophilic (pink to bright red) cytopolasm. Some tumors show more tightly nested or sheet like growth, others are more tubular or microcystic. Another important feature, present on slides of renal cortex are microscopic tumorlets seemingly emanating from eosinophilic tubules. This finding, along with the presence of numerous oncocytic neoplasms is supportive of the above diagnosis. The absence of clinical features to suggest Birt-Hogg-Dube syndrome is noted. Although these tumors are not recognized in the current classification of renal tumors, we regard these neoplasms as being a distinct entity, unrelated to both oncocytoma and chromophobe renal cell carcinoma, and have applied the designation "renal tumor of oncocytosis" to such lesions (Gobbo S, et al. Renal cell neoplasms of oncocytosis have distinct morphologic, immunohistochemical, and cytogenetic profiles. Am J Surg Patholl 34:620-626, 2010). We concur that the expected behavior in these cases is one of indolence." |
Do not report Renal cell neoplasms of oncocytosis. According to our expert pathologist consultant, these neoplasms do not behave "in a malignant fashion." They are not currently classified as malignant and are not reportable to cancer registries. |

20160071 | SEER Summary Stage 2000--Melanoma: Can Clark's level classification still used to Summary Stage melanoma? It was previously used by AJCC TNM, but was not included in the 7th edition. I see it is still listed in the CAP protocols for melanoma. |
Clark's level can be used to assign in situ, localized or regional summary stage.
If there is a discrepancy between the Clark’s level and the pathologic description of extent, use the higher Summary Stage code. |

20160076 | MP/H Rules/Histology--Brain and CNS: What is the histology code for a tumor originating in the cerebellum and extending into the fourth venrticle described as a glioblastoma with primitive neuroectodermal tumor component (WHO Grade IV)? |
The WHO Classification of CNS tumours lists glioblastoma with primitive neuroectodermal tumor component as a subtype of glioblastoma and assigns 9440/3. Also referred to as glioblastoma with a primitive neuronal component. |

20160012 | Reportability--Brain and CNS: Is a thalamic amyloidoma reportable if so what histology code is used? |
Thalamic amyloidoma is not reportable. Amyloidoma (tumoral amyloidosis, amyloid tumor) is a tumor-like deposit of amyloid. It is not neoplastic. Amyloid is a protein derived substance deposited in various clinical settings. |

20160019 | Reportability--Lung: Is a case of pulmonary metastatic leiomyoma (favored) vs. low grade leiomyosarcoma reportable, and if so, what is the primary site and histology code? See Discussion. |
Patient presents with an abnormal chest x-ray. PET reveals 4.6 cm left lower lobe mass and several additional bilateral nodules measuring up to 1.6 cm. Biopsy was recommended and is positive for metastatic histologically benign smooth muscle neoplasm. ER/PR are positive. Mayo consult on biopsy agrees with histology. The differential diagnosis includes benign metastasizing leiomyoma and low grade leiomyosarcoma. Comment: If these nodules remain small and do not progressively grow would consider this metastasizing leiomyoma. Physicians state bilateral pulmonary metastatic leiomyoma (favored) vs low grade leiomyosarcoma. Tamoxifen was started. Patient has a history of uterine fibroids. Several months later, imaging reveals stable bilateral multi pulmonary nodules and left lower lobe mass but persistent. Surgery was recommended but cancelled due to insurance. |
This case is not reportable based on the information provided. The histologic diagnosis is "metastatic histologically benign smooth muscle neoplasm." The physicians seem to agree with the histologic diagnosis, benign metastasizing leiomyoma (BML). The WHO classification and ICD-O-3 assign 8898/1 to "metastasizing leiomyoma." WHO states "This resembles a typical leiomyoma but it is found in the lungs of women with a history of typical uterine leiomyomas." A recent article states "Because of the hormone-sensitive characteristics of BML, treatments are based on hormonal manipulation along with either surgical or medical oophorectomy." Tamoxifen treatment is in keeping with the BML diagnosis. |

20160029 | Radiation Therapy--Breast: Are iodine 125 (I-125) seed implants for breast cancer coded as brachytherapy or as a localization technique similar to wire localization? See Discussion. |
We are seeing many I-125 seed implants for breast cancer. Many of my associates are coding them as brachytherapy. I think they are the newest of the localization technique like wire localization but with greater accuracy. Most are done the same day as the surgery so brachytherapy does not make sense. Which is correct? |
I-125 seeds could be used for brachytherapy for breast cancer or as a localization technique for nonpalpable breast tumors. If the seeds were in place a short time and removed as part of a breast surgical procedure, they were likely used for tumor localization. Radioactive seed localization (RSL) is thought to be more precise than the wire implantation technique for localizing lesions. |

20160036 | Reportability/Histology--Head and Neck: Is mammary analogue secretory carcinoma (MASC) of the left submandibular gland reportable and how is it coded? See Discussion. |
The physician is calling it an indolent tumor, pT3/NX/M0 stage 3 with positive margins. Is the correct code C509, 8502/3? |
Mammary analogue secretory carcinoma (MASC) is reportable. MASC is a recently described tumor that predominantly arises in the parotid gland. In this case, if the primary site is submandibular gland, assign C080. We contacted our expert pathologist and he stated that the best code to use for MASC is 8502/3. Override any edits triggered by the combination of C080 and 8502/3. |
