Our pathologists have starting to use a new prostate cancer grading system that was adopted by WHO in 2016. The new grading scheme correlates with the prior Gleason grading scheme as follows:

Grade Group 1 = Gleason score 6 or less

Grade Group 2 = Gleason score 3+4=7

Grade Group 3 = Gleason score 4+3 = 7

Grade Group 4 = Gleason score 8

Grade Group 5 = Gleason score 9-10

Our pathologists are no longer dictating the Gleason Primary and Secondary Pattern values nor the Gleason's Score. Reverse correlation from the new grade groups to the required patterns and score are difficult with Grade Groups 2 and 3 needing to be distinguished from one another and Grade Group 5 including two unique scores.

The prostate-related fields include:

Collaborative Site Specific Factor 7: Gleason's Primary Pattern and Secondary Pattern Values on Needle Core Biopsy/TURP

Collaborative Site Specific Factor 8: Gleason's Score On Needle Core Biopsy/TURP

Collaborative Site Specific Factor 9: Gleason's Primary Pattern and Secondary Pattern Values on Prostatectomy/Autopsy

Collaborative Site Specific Factor 10: Gleason's Score on Prostatectomy/Autopsy

Pathology report: Brain tumor, left side: Gliotic cortex and subcortical white matter with meningioangiomatosis (see Comment). Comment This specimen represents a meningioangiomatous lesion located in the leptomeninges that projects along the Virchow-Robin spaces into the underlying cortex. The surrounding brain parenchyma demonstrates reactive changes with astrogliosis and microgliosis. An intraparenchymal neoplasm is not seen. Meningioangiomatosis is a rare benign meningovascular hamartomatous condition and usually appears in young patients.

AFS1-AFS2-frozen section control, endomyometrium; AFS3-frozen section control, subserosal intramural mass; A4-anterior cervix; A5-posterior cervix; A6-anterior cervical endometrial junction; A7-posterior cervical endometrial junction; A8-A10-anterior endomyometrium, including tumor; A11-A13-posterior endomyometrium, including tumor and adjacent mass; A14-random section subserosal mass; A15-left parametrium at margin of resection; A16-right parametrium at margin of resection; A17-A18-left ovary and fallopian tube; A19-A20-right ovary and fallopian tube. The final diagnosis includes Endometrial adenocarcinoma, favor serous carcinoma, with papillary and solid areas. Tumor involves: Cervix present, Right ovary, Left ovary, Right fallopian tube, Left fallopian tube, Right parametrium, Left parametrium.

Surgery text indicates TAH-BSO with bilateral pelvic and paraaortic lymph node dissection. The pathology report indicates the specimen includes: Uterine corpus, cervix, bilateral ovaries and fallopian tubes, bilateral parametria. The Gross Description also indicates: Representative sections submitted in 16 cassettes as follows: A1: Anterior cervix A2: Posterior cervix A3: Full thickness anterior lower uterine segment A4: Full thickness posterior lower uterine segment A5: Tumor A6-A7: Full thickness anterior endomyometrium to include tumor A8-A10: Full thickness posterior endomyometrium with tumor A11: Representative sections of right fallopian tube and fimbria A12: Representative sections of right ovary A13: Representative sections of left fallopian tube and fimbria A14: Representative sections of left ovary A15: Right parametrial tissue A16: Left parametrial tissue A17-23: Remainder of cervix.

For example, pathology states: Right axillary lymph node, excision: Diffuse large B-cell lymphoma (DLBCL) (see note). COMMENT: FISH studies were performed that were negative for BCL-6, c-Myc/IgH, CCND1/IgH and IgH/BCl-2 gene rearrangement, ruling out the most common forms of double-hit lymphoma. Flow cytometry studies demonstrated positivity for CD45, CD20, HLA-Dr, CD19, CD11c, CD22, CD30, CD38, CD79b, and FMC7. Low positivity was seen for CD5. No reactivity was seen for CD10, CD23, CD25, CD103 or CD123.

The MP/H Rules (Other Sites Terms and Definitions, Table 2) currently lists a separate mixed germ cell tumor code (9101) for germ cell tumors with choriocarcinoma plus teratoma, seminoma or embryonal carcinoma. Is this separate mixed germ cell tumor code still to be used now that all mixed germ cell tumors (9065 and 9085) have been collapsed into code 9085 for analysis per SINQs 20160056 and 20110013? The current WHO Classification for testis tumors does not list code 9101, but also collapses all seminomatous and nonseminomatous mixed germ cell tumors of more than one histologic type under code 9085.

The physician consult in this case further specifies that the large granular lymphocyte disorder represents an autoimmune disease of autoimmune T-cell mediated mechanism. Is this a reportable diagnosis?

SEER Program Coding and Staging Manual 2016 states: Record size in specified order using a. The largest measurement of the primary tumor from physical exam, imaging, or other diagnostic procedures before any form of treatment. See Coding Instructions 7-9 below. b. The largest size from all information available within four months of the date of diagnosis, in the absence of disease progression when no treatment is administered. #7 Priority of imaging/radiographic techniques: Information on size from imaging/radiographic techniques can be used to code clinical size when there is no more specific size information from a biopsy or operative (surgical exploration) report. It should be taken as a lower priority, but over a physical exam.
