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.
Mets at diagnosis fields--Heme & Lymphoid Neoplasms (Lymphoma): How are Mets at Diagnosis -- Bone, Brain, Liver, Lung, Lymph Node, and Other -- to be coded for lymphomas in 2016? Are they always 0 if the TNM Stage is I, II, or III? How is bone marrow involvement coded -- in which Mets at Diagnosis field?
Note: Answer verified Sept. 2019, still valid for current cases.
Code all mets at diagnosis fields to 0 when the Stage is I, II, or III.
When the lymphoma is Stage IV, one of the mets at dx fields (other than Mets at Dx-Distant lymph nodes) needs to be coded to 1. Stage IV indicates that there is multiple extralymphatic organ involvement, diffuse involvement of an organ; liver, brain, lung or bone involvement, or bone marrow involvement.
For bone, brain, liver, and lung, code these as 1 when these sites are involved and they are not the primary site. This is the same instruction for solid tumor neoplasms.
For mets at dx-distant lymph nodes, always code to 0. For lymphomas, lymph node involvement is included in stage and not based on whether they are regional or distant.
For mets at dx-other, code to 1 for bone marrow involvement or if there is multi extralymphatic organ involvement.
MP/H Rules/Multiple primaries--Thyroid: How many primaries should be reported for a diagnosis of Hurthle cell carcinoma (2.7 cm) and papillary carcinoma (0.3 cm) in the thyroid? See discussion.
SINQ 20110028 includes a note that states "Hurthle cell carcinoma is a synonym for follicular carcinoma according to the WHO." That case is a little different in that the Hurthle cell carcinoma was stated to be a probable follicular variant of papillary carcinoma. The case above does not include that statement.
Is Hurthle cell carcinoma a type of follicular carcinoma? Does rule M6 (follicular and papillary tumors in the thyroid w/in 60 days) apply, report a single primary? Or does rule M17 (tumors with ICD-O-3 histology codes different at the third digit) apply thus leading to multiple primaries (8290 for Hurthle cell and 8260 for papillary thyroid carcinoma)?
Apply rule M6 and report a single primary.
Hurthle cell carcinoma is a snynonym for follicular carcinoma of the thyroid.
Reportability/Histology-Gallbladder: Is high grade biliary intraepithelial neoplasia of the gallbladder reportable?
High grade biliary intraepithelial neoplasia of the gallbladder is reportable. Assign code 8148/2. It is also known as biliary intraepithelial neoplasia grade 3, or BilIN-3.
Multiple primaries--Heme & Lymphoid Neoplasms: Could you please clarify Note 2 found in Rule M10, which is " 'Transformations to' (acute neoplasms) and 'Transformations from' (chronic neoplasms) are defined for each applicable histology in the database." Do the neoplasms being considered have to contain the words 'chronic' and/or 'acute'?
Hematopoietic neoplasms that transform generally don't have 'chronic' or 'acute' as part of their preferred name. The 'chronic' and 'acute' designations are determined by the usual course of the neoplasm. Chronic neoplasms are generally slow growing while acute neoplasms grow fast and are more widespread. Not all Hematopoietic neoplasms transform. Each neoplasm that has the ability to transform has the transformations listed under the 'Transformations to' and/or 'Transformation from' sections in the Hematopoietic database.
For example, Diffuse large B-cell lymphoma (histology code 9680/3) has no histologies/neoplasms listed under 'transformations to.' This means that this neoplasm does not transform to any other neoplasm. There are multiple histologies/neoplasms listed under 'Transformations from' indicating the neoplasms listed under the Transformations from are the chronic neoplasms, and DLBCL is the acute neoplasm. If DLBCL (9680/3) occurs at the same time, within 21 days, or greater than 21 days of any of the histologies listed under 'Transformations From,' rules M8-M13 apply. If DLBCL (9680/3) occurred at the same time as a neoplasm not listed in the Transformations sections, the acute and chronic rules do not apply.
Reportability--Appendix: Is a mucinous cystic neoplasm with high grade dysplasia of the appendix reportable? See discussion.
The language appears similar to the mucinous cystic neoplasm of the pancreas with high grade dysplasia (8470/2), which was clarified to be reportable in 2014.
WHO does not list MCN as a histology for the appendix. This case should be clarified with the pathologist.
For pancreas specifically, the term "mucinous cystic neoplasm (MCN) with high grade dysplasia" replaced the term "mucinous cystadenocarcinoma, noninvasive" according to WHO. MCN with high grade dysplasia of the pancreas is reportable because it is used in place of the now obsolete terminology. If we did not make the new terminology reportable, trends over time could be affected.
Reportability--Eye: Is conjunctival intraepithelial neoplasia (CIN III) from an excision of the left eye conjunctiva reportable?
Conjuctival intraepithelial neoplasia grade III (CIN III) is reportable. Intraepithelial neoplasia, grade III, is listed in ICD-O-3 as /2. It is reportable for sites other than skin.
Neoadjuvant treatment/Grade--Prostate: How should the grade/differentiation field be coded when hormone therapy is given prior to radiation for metastatic prostate cancer? Is hormone treatment "neoadjuvant treatment" in this situation? Per NCCN guidelines, neoadjuvant hormone therapy is strongly discouraged outside of a clinical trial for localized disease. However for metastatic disease, hormone is recommended (gold standard). See discussion.
8/1/15 CT Exam showed enlarged prostate and left seminal vesicle with multiple enlarged pelvic LNs. Findings: suspicious for prostate cancer with invasion of seminal vesicle. Bone scan findings: positive bone mets in multiple sites. PSA 169.0 (elevated). Patient was started on casodex 8/12/15. A prostate biopsy was performed on 9/16/15 to confirm diagnosis, adenocarcinoma Gleason 4+5. Patient's treatment continued with radiation to bone.
For cases diagnosed prior to 2018
Code the grade/differentiation field from the biopsy for this situation. According to experts consulted, hormone therapy does not alter the grade in this case and grade should be coded based on information after hormone therapy when that is the only grade information available.
MP/H Rules/Histology--Testis: How should histology be coded for a testicular primary with a combination of teratoma, yolk sac tumor and embryonal carcinoma? See discussion.
Patient had a radical orchiectomy with the final diagnosis of "Mixed germ cell tumor with the following features -- histologic type: Mixed germ cell tumor (teratoma 50%, yolk sac tumor 25%, and embryonal 25%)."
Assign 9085/3. Code this combination of teratoma, yolk sac tumor, and embryonal tumor in the testis to mixed germ cell tumor (9085/3) based on the WHO Classification of Tumors of the Male Genital Organs.
