Primary Site--Peritoneum: During a second look staging lap following a diagnosis of serous carcinoma of the left ovary, did the physician correctly indicate a new peritoneum, NOS primary for disease described as an endometrioid adenocarcinoma in a "paracaval cyst" that appears to have arisen in endometriosis?
The primary site is C482 [Peritoneum, NOS]. "Paracaval" means alongside or near the vena cava.
Code the site in which the primary tumor originated.
Chemotherapy/Immunotherapy: How do we code Rituxan for Non-Hodgkin Lymphoma and Herceptin for breast cancer? See Discussion.
Page 195 of the SEER Manual 2004 lists these as examples of Immunotherapy. The new SEER*Rx categorizes these as chemotherapy.
(Sinq # 20041025 says to code Avastin and Erbitux as chemotherapy, too.)
Code Rituxan and Herceptin as chemotherapy.
SEER*Rx is effective for cases diagnosed 1-1-2005 and forward. It replaces all previous references. Be sure to use SEER*Rx [http://seer.cancer.gov/tools/seerrx/]
because some agents changed categories when SEER*Rx was deployed.
It is neither required nor recommended that cases treated prior to 2005 be recoded.
Grade, Differentiation/Priorities: Which has priority, the differentiation or the nuclear grade for a liver biopsy histology described as "well differentiated hepatocellular carcinoma, nuclear grade 3/4"?
For most sites, differentiation has priority over the nuclear grade when both are specified (excluding breast and kidney). Assign grade code 1 [well differentiated] to the example above.
CS Lymph Nodes/Scope of Regional Lymph Node Surgery--Prostate: When prostate cancer is an incidental finding at cystoprostatectomy for bladder cancer, is the pelvic lymph node dissection coded for the prostate as well as the bladder?
This answer was provided in the context of CSv1 coding guidelines. The response may not be used after your registry database has been converted to CSv2.
Yes, the pelvic lymph node dissection is coded as regional lymph node surgery for both primaries and the nodes are counted in collaborative staging for both primaries. The examination of the pelvic lymph nodes is relevant to both the bladder and the prostatic primaries.
CS Extension--Kidney: When an incidentally found 5 cm mass discovered on a CT scan during a work-up for colon carcinoma is stated to be consistent with renal cell ca, should the case be staged as localized or unknown when no other information is available related to a work-up for the kidney primary?
This answer was provided in the context of CSv1 coding guidelines. The response may not be used after your registry database has been converted to CSv2.
Code what is known. In the example above, the tumor size and the extension are known and can be coded. The information is limited, but not completely missing.
Code what you DO know rather than coding nothing. Any metastases from the kidney would have been discovered during the workup of the rectal cancer.
Histology--Leukemia: How is "T-Cell prolymphocytic leukemia, cerebriform (Sezary cell-like) variant" coded when the pathology report COMMENT states: The cerebriform (Sezary cell-like) variant accounts for about 5% of cases of T-cell prolymphocytic leukemia?
For cases diagnosed prior to 1/1/2010:
9834/3 [Prolymphocytic leukemia, T-cell type]. According to the WHO Classification of Haematopeietic and Lymphoid Tissue Tumours, cerebriform or Sezary cell-like is a variant form of T-cell prolymphocytic leukemia.
For cases diagnosed 2010 forward, refer to the Hematopoietic and Lymphoid Neoplasm Case Reportability and Coding Manual and the Hematopoietic Database (Hematopoietic DB) provided by SEER on its website to research your question. If those resources do not adequately address your issue, submit a new question to SINQ.
2004 SEER Manual Errata/Grade--Breast: Are the codes on page 94 of the SEER manual's Breast Grading Conversion Table requiring conversion of nuclear grades 1/3 and 1/2 to code 1, 2/3 to code 2, and 2/2 and 3/3 to code 3 correct or are the codes on page C-473 in the Three-Grade System (Nuclear Grade) for breast correct that requires conversion of the same examples to codes 2, 3, and 4 respectively?
On page C-473: Delete the section titled "Three-Grade System (Nuclear Grade)" and delete the table. Use the tables on pages 94 and C-472 to code grade for breast cancer. This correction will be made in the next errata.
2004 SEER Manual Errata/Surgery of Primary Site--Lymphoma: Item 9.a on page 178 is incorrect. Do not assign surgery code 98 to lymphoma, primary in lymph nodes. See Appendix C, page C-707 for Lymphoma (primary in lymph nodes) surgery codes.
Delete item 9. a. i. ii. and iii. on page 178 of the 2004 SEER Manual. This correction will be included in the next errata.
CS Site Specific Factor 3--Prostate: When a prostatectomy specimen shows tumor focally penetrating through the capsule into periprostatic striated muscle tissue, is the involvement coded to 041 [periprostatic tissue] or 052 [skeletal muscle, NOS]?
This answer was provided in the context of CSv1 coding guidelines. The response may not be used after your registry database has been converted to CSv2.
Assign code 052 [Levator muscle, Skeletal muscle, NOS, Ureter]. The description for this case states periprostatic "striated" muscle tissue. According to our pathologist consultant, "striated muscle in this context is skeletal muscle and the term is being used to differentiate the muscle from smooth (non-striated) muscle." Smooth muscle involvement would be most likely be coded 050 [Extension to bladder neck...] because smooth muscle in a prostatectomy or TURP specimen is usually from the urinary bladder neck.
CS Site Specific Factor 4--Prostate: For apex involvement at prostatectomy, is only apical involvement found at prostatectomy included or is all histologically proven apical involvement documented in the second digit of Site Specific Factor 4? See Discussion.
Per note 1 for Site Specific Factor 3 - Pathologic Extension all histologic information is used. Biopsy information would be included when coding path extension. Would all histologic information be used for coding prostatectomy apex involvement in Site Specific Factor 4?
Example 1: Prostate biopsies of the right and left apex and right and left mid gland show adenocarcinoma. Prostatectomy shows bilateral adenocarcinoma. Apex negative for tumor.
Example 2: Prostate biopsies of right apex and mid gland show adenocarcinoma. There is no mention of apex on prostatectomy path. How is CS Site Specific Factor 4 Prostate Apex Involvement coded?
This answer was provided in the context of CSv1 coding guidelines. The response may not be used after your registry database has been converted to CSv2.
Assign the second digit of CS SSF 4 based on prostatectomy only, do not include biopsy or other histologic information in the second digit.
According to the CS Steering Committee, the clinical or biopsy of the prostate is included in the first number of the code and should not be combined with the prostatectomy code which is the second number. These were separated purposely.
Example 1: Code the second digit of SSF 4 based on the prostatectomy, 1 [no involvement of prostatic apex].
Example 2: Code the second digit of SSF 4 based on the prostatectomy, 5 [apex extension unknown].
