Behavior Code--Breast: How is this field coded for a "non-invasive Paget disease of the breast?" See Discussion.
Historically, SEER collected Paget Disease of the breast with a behavior code of 3 [invasive]. There is no documentation to support this. The SEER EOD Manual only states that if the code is "05" [Pagets disease (without underlying tumor)], the behavior must be a 2 [in situ] or a 3 [invasive].
Code the behavior as /2 [in situ] for noninvasive Paget disease of breast. Noninvasive is a synonym of in situ.
If the pathology report documents that the Paget disease is in situ, the matrix principle in ICD-O allows you to change the behavior code to match the pathologist's statement.
Histology (Pre-2007)--Lung: What is the correct histology code for this case of squamous cell carcinoma with several different variants? See Discussion.
The path report from a left pneumonectomy says: This squamous cell carcinoma had several different variants present including typical non-keratinizing squamous cell, spindled cell squamous cell, clear cell squamous cell and a small cell variant of squamous cell.
I cannot find a combination code that fits; the majority of the tumor is not stated; so do you code the highest specific type mentioned - 8084 - Squamous cell, clear cell type?
For tumors diagnosed prior to 2007:
Assign histology code 8070 [squamous cell carcinoma, NOS]. Squamous cell carcinoma, NOS includes types of squamous cell carcinoma without a specific code. This is a combination squamous tumor that does not have a unique code.
For tumors diagnosed 2007 or later, refer to the MP/H rules. If there are still questions about how this type of tumor should be coded, submit a new question to SINQ and include the difficulties you are encountering in applying the MP/H rules.
CS Extension--Colon: What is the difference between codes 46 [Adherent to other organs or structures, but no microscopic tumor found in adhesion(s)] and 57 [Adherent to other organs or structures, NOS]? See Discussion.
Code 46 reads "Adherent to other organs or sturcture, but no microscopic tumor found in adhesion(s)".
Would these examples be coded to 46?
Example 1: 7/04 Op findings: mass was adherent to duodenum without obvious invasion. Path: margins negative (no mention of duodenum). Case staged to pT3.
Example 2: Op findings: large mass involving cecum adherent to peritoneum & retroperitoneum. Path: invasion of pericolic soft tissue; margins negative (no metion of peritoneum & retroperitoneum). Case staged to pT3.
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 46: Attached to other organ (on imaging or surgical observation); pathology says no invasion of the other organ. Code 57: Attached to other organ; pathology is positive for invasion of other organ, or pathology does not specify whether there is invasion of the other organ.
Example 1: Code extension to 46 [Adherent to other organs or sturcture, but no microscopic tumor found in adhesion(s)]. The tumor was attached to the duodenum, but not invading
Example 2: Code extension to 46 [Adherent to other organs or structure, but no microscopic tumor found in adhesion(s)]. The tumor was attached to peritoneum & retroperitoneum, but not invading based on negative margins and no peritoneum or retroperitoneum specimen submitted to pathologist.
CS Site Specific Factor 6--Breast: Can we interpret the in situ component as "minimal" when the pathology report states "1.1 cm infiltrating duct carcinoma and no extensive intraductal component"?
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. Based on the information provided above, the in situ component is "mininmal" for the purpose of coding Breast CS Site Specific Factor 6. The phrase "no extensive intraductal component" suggests that there is some intraductal carcinoma present.
Reporting Source: Is an ER patient who is diagnosed on peripheral smear with an acute leukemia coded as an outpatient if the patient died while in the process of being admitted for treatment or is the patient coded as a death certificate case?
Code reporting source as 1 [Hospital Inpatient/Outpatient or Clinic] for the case above. This case will be abstracted using information from the outpatient/ER record (and the death certificate).
Histology (Pre-2007)--Colon: Must a case be specifically labeled "familial adenomatous polyposis" or is the mere presence of numerous/multiple polyps sufficient for coding the histology to FAP?
For tumors diagnosed prior to 2007:
The presence of numerous/multiple polyps is not necessarily adenomatous polyposis coli. Adenomatous polyposis is an extreme condition usually characterized by the presence of hundreds of polyps and should be identified as such either clinically or pathologically.
Look for the term "Familial adenomatous polyposis," FAP or one of its synonyms:
Adenomatosis of the colon and rectum [ACR]
Familial adenomatous colon polyposis
Familial colonic polyposis
Multiple familial polyposis
In the absence of these terms, the following probably indicate a diagnosis of FAP:
Hundreds of adenomatous polyps throughout large intestines, and at times, throughout the digestive system
Development of polyps as early as ten years of age, but more commonly at puberty
History of colectomy
For tumors diagnosed 2007 or later, refer to the MP/H rules. If there are still questions about how this type of tumor should be coded, submit a new question to SINQ and include the difficulties you are encountering in applying the MP/H rules.
Date Therapy Initiated/First-Course of Cancer-Directed Therapy Fields/Summary Stage 2000--Prostate: How do you code these fields for a case that received preventative chemo before a definitive cancer diagnosis?
A patient has a "suspicious but not diagnostic" biopsy of the prostate in 09/2002. Doctor said it was not cancer and put the patient on a preventative chemo drug study (GTX-211). The patient returned for a repeat biopsy on 04/2003. Biopsy returned positive for adenocarcinoma. The patient had not been diagnosed when chemo was administered. Can the case be staged using the post-chemo information?
Stage this case the same as all other cases. Use only the information subsequent to the date of diagnosis to code stage and treatment.
The diagnosis date in the example is 04/2003. Do not use information prior to 04/2003 to code stage or treatment. Do not code the preventative chemo as treatment.
Ambiguous Terminology/Reportability: Are the terms "bordering on" and "may represent" diagnostic of cancer? See Discussion.
Pathology report states "...florid micropapillary hyperplasia, focally atypical with features bordering on low grade micropapillary ductal carcinoma in situ."
The terms "bordering on" and "may represent" are not diagnostic of cancer. These terms are not on the list of ambiguous terms that constitute a diagnosis of cancer. The diagnosis in the example above is not reportable to SEER.
Date of Diagnosis: When a 4/04 clinical impression indicates the appearance of a carcinoma that is contradicted by a negative 4/04 biopsy but is confirmed by a 5/04 resection, should the diagnosis date be coded to April or May? See Discussion.
4/04 colonscopy: irregular fungating mass that has appearance of carcinoma. 4/04 Bx: high grade dysplasia. 5/04: LAR. 5/04 Path: 3.2 X 2.5 cm mass wd adenoca with invasion of muscularis propria.
Should the diagnosis date be 4/04 based on the clinical impression during the colonoscopy OR 5/04 since the path for the bx was negative?
The date of diagnosis for the example above is 05/04 -- the date of the pathology report confirming malignacy. The biopsy in 04/04 negated the 04/04 clinical statement.
