Reportability--Breast: Is a biopsy proven squamous cell carcinoma of the breast nipple reportable if a subsequent areolar resection shows foreign body granulomatous reaction to suture material and no evidence of residual malignancy in the nipple epidermis?
Yes, this case is reportable. The primary site is C500 [nipple]. There was a diagnosis of malignancy on 2/15/06: "Positive for malignancy." Even though no residual malignancy was found in the later specimen, that does not disprove the malignancy diagnosed on 2/15/06.
CS Extension/CS Mets: For primary sites within the peritoneum (abdominalpelvic walls) such as stomach, colon, does the presence of malignant ascites affect the coding of CS Extension or CS Mets?
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.
The Collaborative Staging system is governed by site-specific coding rules. Refer to each set of site rules rather than looking for a general answer for all sites in peritoneum. In particular, Ovary and Corpus allow malignant ascites to be coded in CS Extension, but not CS Mets at Dx. For each site, both CS Extension and CS Mets at Dx should be checked for the proper field to code malignant ascites.
Histology (Pre-2007)--Bladder: How is a "carcinoma with squamous, mucinous, and signet ring cell features" coded?
For tumors diagnosed prior to 2007:
Code histology to 8490 [Signet ring cell carcinoma]. Rule 7 on page 87 of the 2004 SEER Manual applies to this case.
Rule 7: Code the numerically higher ICD-O-3 code. This is the rule with the lowest priority and should be used infrequently.
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 Lymph Nodes: Are positive right superficial inguinal lymph nodes coded to 30 (which is the case for anal canal primaries) or 31 (which is the case for anus primaries) if the primary is stated to be in the "cloacogenic zone" or is an anorectal 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.Assign code 30 for positive unilateral superficial inguinal lymph nodes for cloacogenic primaries. The cloacogenic zone is part of the anal canal.
Diagnostic Confirmation: How is this field coded for a case with a cytology that is suspicious for ductal carcinoma and the clinical diagnosis is carcinoma? See Discussion.
SINQ 20031152 states that histology for this type of case is to be coded per the clinical diagnosis of "carcinoma." Does it follow then that Diagnostic Confirmation is to be coded 8 (clinical diagnosis only)? Would we code Diagnostic Confirmation differently if the clinician stated that the diagnosis of malignancy was confirmed by the suspicious cytology?
Code diagnostic confirmation as 8 [clincial diagnosis] when there is a suspicious cytology and a physician's clinical diagnosis. Do not accession cases with only suspicious cytology.
Code diagnostic confirmation as 8 when the clinician's diagnosis of malignancy is confirmed by the suspicious cytology. It is still a clinical diagnosis made by the physician using the information available for the case.
Reportability--Brain and CNS: Is Langerhans cell histiocytosis [9751/1] of the meninges [C709] reportable?
For cases diagnosed prior to 1/1/2010:Yes. The criteria for reportable benign/borderline CNS tumors is based on location (site) and behavior (benign/borderline). There is no caveat for histologic type. Therefore, this would be reportable as these tumors have been reported arising from the meninges or choroid plexus.
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.
Surgery of Primary Site--Lung: Is this field coded to 30 [Resection of lobe or lobectomy] or 33 [Lobectomy with mediastinal lymph node dissection] when a lobectomy specimen includes 2 AP window lymph nodes? See Discussion.
LUL lobectomy: 1.7cm apical tumor, DX=mod well diff subpleural SCC, with involvement of pleural surface. 3 peribronchial LN neg and 2 AP window LNs neg. Stage T2N0.
1. No lymph node dissection or sampling was stated to be done
2. The lobectomy specimen contained the LNs
3. Scope of regional LN surgery is coded
Would the surgery to primary site code 30 or 33?
Code surgery of primary site to 30 [Resection of lobe or lobectomy]. According to the information provided, there was no lymph node dissection in this case. The 2 AP window nodes were obtained as part of the lobectomy specimen.
CS Lymph Node Examined--Lung: How is this field coded when a mediastinoscopy and lobectomy are performed and the pathology report indicates multiple lymph node fragments were removed as biopsy specimens and the lobectomy specimen revealed 3 interlobar lymph nodes?
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 the CS Lymph Node Examined field to 98 [number unknown] because the biopsy information is not clear and as a result you do not know how many lymph nodes were examined.
CS Extension/CS Mets at Dx--Peritoneum: How are these fields coded for extraovarian peritoneal carcinomas presenting with multiple peritoneal implants? See Discussion.
Patient presented with large omental cake and multiple peritoneal implants including implants on the rectosigmoid serosa and right ovary. Path revealed papillary serous adenocarcinoma consistent with peritoneal primary.
Per AJCC Manual, extraovarian peritoneal carcinoma is usually staged with the ovarian staging classification.
We understand that the CS Manual will eventually be revised to include staging for extraovarian peritoneal primaries. In the meantime, how do we use the existing CS scheme for peritoneum to code these cases?
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 CS Extension 99 [unknown] and CS Mets at DX 99 [unknown].
The issue has been sent to the CS steering committee for resolution. This answer will be updated when the steering committee provides a resolution.
