CS Site Specific Factor 6--Breast: Should we assume that the invasive portion of the tumor is being referred to when a pathologist provides only a single tumor size but includes both invasive and in situ descriptors when discussing the size of that tumor? See Discussion.
There seems to be subtle variations in wording and punctuation in these cases. Would these three examples be coded the same way?
Examples:
"invasive ductal carcinoma 2.0 cm, DCIS present"
"2 cm invasive ductal carcinoma with DCIS present"
"invasive ductal carcinoma 2.0 cm. DCIS present"
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 SSF6 050 [invasive and insitu components present, entire size coded in CS TS, size of invasive not stated, proportion invasive and insitu not known] when the size of the invasive portion is not provided and clarification is not available.
If possible, obtain clarification from the pathologist for phrases like these and document in a text field. For example, a pathologist may confirm that when he/she states "invasive ductal carcinoma 2.0 cm, DCIS present" the size of the invasive portion is 2 cm. If so, code CS tumor size 020 and SSF6 020 and explain in a text field.
MP/H Rules--Lung: In reference to lung, SINQ 20071028 states "'nodule' is not an equivalent term for tumor, mass, lesion, or neoplasm." However, slide 5 for the MPH lung section of "Beyond the Basics" states "we use the words 'mass, nodule and lesion' interchangeably." Which is it?
For cases diagnosed 2007 or later:
For the purpose of applying the Lung MP/H rules, the word "Nodule" can be used interchageably with "Tumor," "Mass," "Lesion" and "Neoplasm." HOWEVER, this does NOT apply to casefinding or staging.
This revision will be added to the next version of the MP/H rules. Sinq question 20071028 will be revised.
MP/H Rules/Histology--Thyroid: How would the histology "micropapillary carcinoma" of the thyroid be coded for cases dx'd 2007 and after?
For cases diagnosed 2007 or later, assign code 8260/3 [Papillary adenocarcinoma] according to rule H14.
For thyroid cancer only, the term micropapillary does not refer to a specific histologic type. It means that the papillary portion of the tumor is minimal or occult, usually less than 1 cm. in diameter.
Multiplicity Counter: Should this field be coded to 99 for cases of familial adenomatous polyposis (FAP)? See Discussion.
The MP/H rules state to abstract these cases as a single primary. The Type of Multiple Tumors Reported as One Primary field is coded as a single primary with a value of 32 (FAP with carcinoma), but the Multiplicity Counter seems to be unknown.
Assign code 99 [Multiple tumors present, unknown how many] for cases of FAP when the number of tumors is not stated.
MP/H Rules/Histology--Colon: How do you use Rule H5 or H6 to code "moderately diff adenoca with mucinous component"?
For cases diagnosed 2007 or later, code the histology 8140 [Adenocarcinoma]. Rule H6 applies because the final diagnosis is not "mucinous adenocarcinoma" and the percentage of mucinous adenocarcinoma is not stated.
Rule H13 does not apply because "component" is not a term that indicates a specific histology.
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 Extension--Lymphoma: When does the coding change take effect that is referred to in SEER edit IF195, that states localized lymphoma in primary sites C024, C090-099, C111, C142, C172, C181, and C379 must be coded to CS extension 10, and cannot be coded to extension 11? See Discussion.
CS version 1.04 does have a new note 1 in the lymphoma scheme that appears this coding change. In the past, we used code 11 with these sites for localized lymphoma and SINQ 20061088 confirms this line of thinking.
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.
This change was made with the release of CS version 01.04.00 on October 31, 2007. The rules went into effect for cases diagnosed January 1, 2008 and later. A note was added to SINQ 20061088 stating that the answer pertains to cases diagnosed prior to January 1, 2008.
First course treatment--Prostate: If a patient has a prostatectomy and the margins are positive, then several months later radiation is given because the PSA levels never decreased or have risen, is the radiation coded as first course of treatment or subsequent treatment?
Record the radiation as first course of treatment even though it was delayed for several months.
Radiation is highly effective when there is a small or microscopic amount of tissue left at the margin following prostatectomy. In most regions, radiation therapy is the standard of care for positive margins at prostatectomy.
Extension/CS Extension--Prostate: Do the prostate guidelines used for EOD still apply to cases diagnosed 2004 forward?
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.For cases diagnosed 2004 and forward, refer to the Collaborative Staging manual.
The 2004 CS guidelines have been agreed upon by all standard setters and have been reviewed by the COC/AJCC urologists.
Note: Do not use the SEER EOD guidelines with Collaborative Staging.
