20170036 | Grade--Prostate: How are the prostate-related fields completed when documentation in pathology reports only includes one of the new grade groups? See Discussion. |
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 |
When all you have is the grade group, you may use the following table to convert the Prostate Grade Groups to the appropriate code for the indicated fields. Grade Group Gleason Score Gleason Pattern SSF7 SSF8 SSF9 SSF10 Grade/diff Grade Group 1 6 or less <=3+3 099 999 099 999 1 Grade Group 2 7 3+4 034 007 034 007 2 Grade Group 3 7 4+3 043 007 043 007 2 Grade Group 4 8 4+4, 3+5, 5+3 999 999 999 999 3 Grade Group 5 9-10 4+5, 5+4, 5+5 099 999 099 999 3 |

20170055 | First Course of Treatment/Surgery of Primary Site--Corpus uteri: Do you code total hysterectomy or radical hysterectomy when a specimen indicates the uterus, cervix, ovaries, fallopian tubes, and right and left parametrium were resected, but shows no portion of the vagina. See Discussion. |
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. |
Assign code 50 for total hysterectomy. According to Appendix C Surgery Codes for Corpus Uteri of the 2016 SEER Coding and Staging Manual, total hysterectomy is surgery to remove the entire uterus, including the cervix; whereas, radical hysterectomy includes the vagina. |

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. |

20170078 | Scope of Regional Lymph Node Surgery--Lung: How do you code Regional Nodes Positive, Regional Nodes Examined, and Scope of Regional Lymph Node Surgery when a fine needle aspirate (FNA) or biopsy of supraclavicular lymph nodes is positive for a lung cancer primary? Supraclavicular lymph nodes are distant in SEER Summary Stage and regional by AJCC. See Discussion. |
There is a discrepancy in regional lymph nodes for lung between SEER and AJCC. Supraclavicular lymph nodes/cervical lymph nodes are distant for SEER but regional for AJCC. For SEER states, when there is an FNA or biopsy of a supraclavicular lymph node performed and it is positive for a lung primary and no other lymph nodes are examined, do you code 95 in Regional Nodes Positive/Regional Nodes Examined and code "1" for Scope of Regional Lymph Node Surgery or do you not count the FNA/biopsy of the supraclavicular lymph node since it is distant? |
For cases diagnosed through 2017, use the Collaborative Staging (CS) system to determine regional versus distant lymph nodes. Supraclavicular lymph nodes are regional for lung in CS. Please note that Summary Stage is not the same as EOD, CS, or AJCC staging. Registrars should not use Summary Stage definitions for anything other than directly assigning the Summary Stage field. |

20170073 | Histology/Behavior--Brain and CNS: How are histology and behavior coded for a diagnosis of pineal anlage tumor in an infant? See Discussion. |
Patient is an 11 month old with brain biopsy showing final diagnosis of pineal anlage tumor. How are behavior and histology coded for this rare tumor? |
Assign 9362/3 for pineal anlage tumors. According to the WHO Classification of Tumors of the Central Nervous System, 4th edition, pineal anlage tumors, while extremely rare, share features with pineoblastoma. Although they have a distinct morphology, there is no other ICD-O-3 code for pineal anlage tumors. |

20170006 | Diagnostic confirmation--Heme & Lymphoid Neoplasms (Lymphoma): To code "3" in Diagnostic Confirmation, does the genetic testing need to confirm a specific histology or is it enough that is simply rules out others? See Discussion. |
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. |
Both histologic plus immunophenotyping or genetic testing should be positive to assign code 3 for Diagnostic Confirmation. The Hematopoietic and Lymphoid Neoplasm Coding Manual Diagnostic Confirmation instructions state, assign 3 for Cases positive for neoplasm being abstracted (including acceptable ambiguous terminology and provisional diagnosis) AND Immunophenotyping, genetic testing, or JAK2 is listed in the Definitive Diagnosis in the Heme DB AND a.) Confirms the neoplasm OR b.) Identifies a more specific histology (not preceded by ambiguous terminology). Because the patient was diagnosed with DLBCL by histology, and flow cytometry was positive for CD antigens (immunophenotyping) 20, 22, and 30 for DLBCL, code 3 is appropriate. |

20170010 | CS Site Specific Factor--Breast: What estrogen receptor/progesterone receptor (ER/PR) values should be coded in a case with two separate tumors (1 ductal, 1 lobular) diagnosed simultaneously in the same breast (single primary) with differing ER/PR values for each tumor? One is ER/PR positive; the other is ER/PR negative. |
In cases where ER (or PR) is reported on more than one tumor specimen, record the highest value. If any sample is positive, record as positive. Guidance on Collaborative Stage (CS) site-specific factors (SSFs) in the breast schema can be found in the SEER Registrar Staging Assistant (SEER*RSA): SSF1-Estrogen Receptor (ER) Assay and SSF2-Progesterone Receptor (PR) Assay. The SEER* RSA breast schema is found at: https://staging.seer.cancer.gov/cs/schema/02.05.50/breast/?breadcrumbs=(~schema_list~) |

20170018 | MPH Rules/Multiple primaries--Melanoma: Does MP/H Rule M7 (diagnosed more than 60 days apart) apply to invasive melanoma cases with margins positive for in situ melanoma, or are these further excision of the original diagnosis and the same primary, even when it appears treatment was complete after the initial excision? See Discussion. |
A dementia patient has been managed for a persistent right cheek skin lesion that has been slow growing for about 5 years. It was biopsied in 12/23/15 revealing a Breslow 0.12 mm lentigo maligna melanoma by an outside provider. A larger resection of the lesion on 2/3/16 demonstrated a Breslow 0.30 mm lentigo maligna melanoma with melanoma in situ present at the margins per the available pathology report. There was no statement in the record that any additional treatment was planned or necessary. Patient healed well from the 2/3/16 procedure but developed a recurrent lesion in May that was biopsied on 5/10/16 by the same outside provider which again reveal lentigo maligna melanoma. 7/5/16 Reexcision at the current facility revealed a Breslow 6.1 mm lentigo maligna melanoma, Clarks level V. This was a cutaneous tumor per the path report and not a subcutaneous nodule. Clinically, the MD called this a , but there was no slide comparison to the previous melanoma. In auditing files for expected (but not received) abstracts due from facilities, we've observed these types of cases not being consistently reported as multiple primaries. |
Rule M7 pertains to separate tumors. Rule M7 does not apply to invasive melanoma cases with margins positive for in situ melanoma. Based on the information provided, it is not clear whether or not the 5/10/16 diagnosis is a separate lesion or the same lesion that was diagnosed earlier. |

20170057 | Grade: If the biopsy site is a higher grade, is the grade of the biopsy used over the grade of the surgical resection? See Discussion. |
When coding tumor grade, our pathologists have told us to code grade based on the specimen from the most definitive surgery or with the most amount of tissue, and that coding grade from the biopsy would not be appropriate even if it is a higher grade than from the surgical resection. Coding of solid tumors Instruction 5 states: If there is more than one grade, code the highest grade within the applicable system. Code the highest grade even if it is only a focus. Code grade in the following priority order using the first applicable system. |
For cases diagnosed prior to 2018: Use the Grade Coding Instructions to code grade. The instructions are intended to standardize coding of grade across the U.S. and to eliminate differences in opinion between pathologists. Standardized coding ensures that data can be combined and used for statistical analysis. You may code grade based on the biopsy when following the grade coding instructions. |

20170014 | Reportability/Histology--Heme & Lymphoid Neoplasms: Is a physician statement that a patient has a malignant histiocytic disorder best described as Erdheim-Chester disease reportable? If reportable, should histology be coded to 9751/3? See Discussion. |
The patient had a mediastinal mass biopsy showing fibrosclerotic tissue with patchy lymphohistiocytic foci and scattered plasma cells, followed by a retroperitoneal mass biopsy showing fibrohistiocytic infiltrate. Erdheim-Chester disease is not reportable per the Heme Database. However, the physician specifically states this is a malignant disorder. |
Erdheim-Chester disease is not reportable. Use the Hematopoietic and Lymphoid Neoplasm Database to determine reportability. The WHO Classification of Tumors of Hematopoietic and Lymphoid Tissues states that Erdheim-Chester disease is a possible adult form of disseminated juvenile xanthogranuloma with bone and lung involvement; no histology code is provided. |
