CS Extension/Ambiguous terminology--Pancreas: Should an exception be made for "abuts" or "encased/encasing" regarding CS pancreas extension? See Discussion.
According to the CS Manual regarding ambiguous terminology, we do not accept "abuts" or "encased/encasing" as involvement. According to the March/April 2008 issue of "CA, A Cancer Journal for Clinicians", vol 58, number 2, an article concerning Pancreas staging by M.D. Anderson researchers/clinicians recommends defining unresectable involvement of the celiac axis/mesenteric artery with the terms "abutment" as involvement of 180 degrees or less of the circumference of the vessel, and "encasement" as more than 180 degree involvement. A large comprehensive cancer center in our area has already adopted these guidelines.
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.Follow the current CS instructions regarding ambiguous terminology. "Abuts" and "encased/encasing" are not involvement.
The American College of Surgeons Commission on Cancer provided the following in response to this question: This concept can be considered for CS version 2, but it would need to be made in conjunction with acceptance of that same theory in AJCC 7th Edition so that the stage can be derived. Many times what can be defined and accepted in a closed environment of a single institution research project cannot be duplicated and accepted across the nation and in every community facility. Would pathologists specify the > or < 180 degree involvement in every pathology report? It would also have to be reviewed to see if this idea has been accepted by the larger oncology community, or just the idea of a single institution.
Surgery of Primary Site--Breast: How is this field coded when a re-excision follows a prior mastectomy?
Code the most extensive surgery in Surgery of Primary Site. This is a cumulative field. Assign the appropriate code including all surgeries of the primary site performed during the first course of treatment.
The correct code for mastectomy followed by re-excision will depend on the extent of the re-excision. For example, if the re-excision removed muscle, code radical mastectomy.
Histology--Breast: What is the histology code for a 2007 diagnosis of basal-type breast carcinoma?
Code basal-type breast carcinoma to 8500/3 [Infiltrating duct carcinoma, NOS].
Basal-type breast carcinoma is a subtype of infiltrating duct carcinoma thought to have a poorer prognosis. There is no specific ICD-O-3 code for basal-type breast carcinoma.
Reportability--Brain and CNS: Is a cavernoma reportable as a benign brain tumor? See Discussion.
Cavernous hemangiomas are typically described as vascular malformations in the brain. Per a search of the literature, cavernoma, cavernous hemangioma and cavernous malformation are all synonymous. There is some controversy as to whether cavernomas are vascular malformations or tumors. Cavernous hemangioma (9121/0) has been assigned a code in the ICD-O-3. The other terms are not even listed. Benign brain guidelines indicate that named tumors that have been assigned an ICD-O-3 code are reportable. Would we report a lesion that is labeled cavernous hemangioma but not one that is labeled carvernoma? Are cavernous malformations of the brain to be reported as benign brain tumors? The MP/H guidelines for benign brain tumors do not include blood vessel tumors in chart 1.
Are the following tumors reportable? If so, what is the primary site?
Example 1: Patient admitted for resection. Clinical diagnosis is left temporal cavernous hemangioma. Path diagnosis is cerebral cortex and white matter showing cavernoma.
Example 2: Patient admitted for resection with clinical diagnosis of parietal cavernous hemangioma. Path shows A-V malformation.
Example 3: Patient had T4 spinal tumor removed. Path showed cavernous angioma.
Reference: I&R 18109 and 23460
Cavernoma is a reportable benign brain tumor. According to our pathologist consultant, cavernoma is synonymous with cavernous hemangioma.
Examples
1. Reportable. Primary site - C710 [cerebrum]
2. Not reportable. Path dx disproves clinical diagnosis.
Reportability/Diagnostic Confirmation: If a physician signs a case out as "precancerous melanosis of the face" (8741/2) and there is no microscopic confirmation of the disease, is this a reportable clinical diagnosis?
This case is reportable because the diagnosis of precancerous melanosis was stated by a recognized medical practitioner. Precancerous melanosis meets the reportable diagnosis criteria (See 2007 SEER Manual page 1).
Laterality--Brain and CNS: When a meningioma extends to both right and left sides, is laterality coded 4 for bilateral or 9 for midline? See Discussion.
Operative Findings: Bilateral frontal craniotomies for excision of giant meningioma which extended onto optic chiasm.
Path: Bifrontal tumor, 6.5 cm meningotheliomatous meningioma.
If it is not possible to determine whether the meningioma originated on the left or the right, assign code 4 [Bilateral involvement, lateral origin unknown; stated to be single primary].
CS Lymph Nodes--Breast: Now that code 50 [fixed/matted ipsilateral axillary LNS, NOS] is obsolete, how is this field coded for a case in which there are clinically matted lymph nodes, no neoadjuvant therapy, and no lymph node size on the available pathology report?
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.From the American College of Surgeons: The pathologic information always takes precedence over the clinical information when there is no neoadjuvant therapy. The size reference is that this is not ITC or micromets. Clinically, I don't think you can have fixed or matted nodes that aren't greater than micromets. This would be coded to 52. The mapping for all of these codes is not taken from this, but from the value of SSF3 per the note at the bottom of the table. See CS Lymph Nodes note 2.
Reportability/Histology--Head and Neck: Is a right cerebellopontine (CP) angle endolymphatic sac papillary tumor (ELST) reportable? If so, what is the histology code?
Revised December 2015
ELST is reportable. Code histology to adenocarcinoma (8140/3). Code primary site to inner ear (C301).
Endolymphatic sac tumors are rare non-metastasizing adenocarcinomas that originate in the endolymphatic sac of the inner ear (C301). They are slow growing and widely invade, and in later stages often destroy, the petrous bone. The WHO Classification assigns ICD-O-3 code 8140/3.
Reportability: Is a case reportable if a benign diagnosis is obtained on a resection that follows a positive needle aspiration? See Discussion.
Fine needle aspiration of the thyroid diagnosis was "positive for malignant cells, favor medullary carcinoma." Subsequent thyroidectomy was reported as benign.
This case is reportable. The cytology is positive. Report as medulary carcinoma of the thyroid.
