CS Lymph Nodes/CS Mets at DX--Ovary: How are the following lymph node regions/chains coded in the Collaborative Stage schema for ovary?
1. pericolonic
2. pelvic, NOS
3. mesenteric, 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.Revised 7-17-09
Assign CS Lymph Nodes code 10 for involvement of pelvic lymph nodes, NOS.
Code involvement of pericolonic nodes or mesenteric nodes, NOS in CS lymph nodes.
CS Lymph Nodes/Reg LN Pos/Exam: Is a final pathologic diagnosis of "Level 8 lymph node: Fibroadipose tissue containing a minute lymphoid aggregate, negative for malignancy" a lymph node for the purpose of coding these fields?
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. "Fibroadipose tissue containing minute lymphoid aggregate" qualifies as a lymph node. Include in count as one lymph node examined in the example above assuming this is regional to the primary site.
CS Site Specific Factor 6--Breast: If the tumor size for the breast is unknown, and it is unknown whether the tumor is mixed in situ and invasive or "pure", how is SSF6 to be coded? See Discussion.
The definition for SSF6 for breast changed from "Unknown if invasive and in situ components present, unknown if tumor size represents mixed tumor or a pure tumor" to an added clarification of "Clinical tumor size coded." Since the clinical tumor size is NOT coded, this does not fit.
The definition for 060 is "Invasive and in situ components present, unknown size of tumor (CS Tumor Size coded 999). Since it is unknown if the tumor is mixed, this definition does not fit either.
It seems that the revised (April 2005) definition for 888 has left a situation that cannot be 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.SSF 6 should be coded 888 in this case. SEER will make the CS task force aware of this situation.
CS Site Specific Factor--Breast: If the tumor is described as being a 1 cm poorly differentiated pleomorphic lobular carcinoma with scattered LCIS in breast tissue, for SSF6, do we use the breast tumor or all of the breast tissue removed when coding SSF6?
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.
Site Specific Factor 6 in the breast scheme describes the relationship of invasive and in situ tumor in the tumor size coded. Code SSF6 for the same tumor used to code tumor size.
For this example, code SSF6 for the 1 cm tumor. In this case, the entire tumor is reported as invasive; use code 000 [Entire tumor reported as invasive].
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.
CS Site Specific Factor--Prostate: Can autopsy results also be used when coding SSF3, pathologic extension, given that the instructions only address the use of prostatectomy findings when coding this field?
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.
If the prostate cancer was diagnosed on autopsy, or the autopsy was performed within the staging timeframe (See 2004 SEER Manual, page 112), code SSF3 using the autopsy information.
CS Site Specific Factor--Prostate: Explain the difference among SSF4 prostate codes 150 [No clinical involvement of prostatic apex & prostatectomy apex extension unknown], 510 [Clinical involvement of prostatic apex unknown & No prostatectomy apex extension], and 550 [Clinical involvement of prostatic apex unknown & prostatectomy apex extension unknown].
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.Site Specific Factor 4 captures the status of clinical apex involvement and prostatectomy apex involvement. The first digit in codes 110-550 indicates the clinical status of apex involvement. The second digit indicates apex involvement found at prostatectomy. The third digit is always zero. For both first and second digits, the codes and definitions are the same:
1 - No involvement of prostatic apex
2 - Into prostatic apex/arising in prostatic apex, NOS
3 - Arising into prostatic apex
4 - Extension into prostatic apex
5 - Apex extension unknown
Code 150 = No clinical involvement of prostatic apex & prostatectomy apex extension unknown
Code 510 = Clinical involvement of prostatic apex unknown & No prostatectomy apex extension
CS Tumor Size--Breast: When the diagnosis is inflammatory carcinoma of the breast, must the CS tumor size always be 998? See Discussion.
I have no specific example of a situation; I am writing an edit check and wondering if there would be any exceptions to this rule.
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.No. For inflammatory carcinoma, code the size of the tumor in CS tumor size. Use code 998 [diffuse] when the tumor is stated to be "diffuse."
Page 27 in Part I of the CS manual will be corrected to define code 998 for breast as only "diffuse." The errata should be distributed in July 2004.
CS Tumor Size: Can an 'ulcerated mass' be used to code CS tumor size? See Discussion.
The CS Manual (p. 26, 4.a.) states do not code the size of the polyp, ulcer or cyst. However it states that a 'cystic mass' can be used to code TS if it is the only size given. Scopes Text: 'ulcerated' mass based at anal verge & ext 3-4 cm up into rectum.
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.Do not code CS Tumor size using the size of an ulcerated mass.
CS Tumor Size: Is a measured "area" equivalent to a tumor, mass or lesion size? See Discussion.
Collaborative Stage manual, page 26
Rule 4a: "always code size of the primary tumor, not size of the polyp, ulcer, cyst or distant metastasis."
Rule 4e: Additional rule for breast primaries: Example: Duct carcinoma in situ covering a 1.9 cm area with focal areas of invasive ductal carcinoma. Record the tumor size as 1.9 cm.
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.In general, a measured area is not equivalent to a tumor size.
Do not apply the rule related to the breast example to other primary sites. This example in the CS manual pertains to coding tumor size for breast primaries when the size of the invasive component is not stated. In the example, the area involved with duct carcinoma in situ is the only measurement available. The size of the invasive component was not given.
