Other Cancer-Directed Therapy--Hematopoietic, NOS: Is there a hierarchy for selecting which code to use when a patient receives more than one type of "other treatment"? See Description.
Patient was diagnosed with Myelodysplastic Syndrome, probably refractory cytopenia with multilineage dysplasia. Good candidate for investigational studies for transfusion-dependent patients. Patient was enrolled in a high dose vitamin D study. Patient also received transfusions.
SEER has not established a hierarchy of the codes listed under Other Treatment. If the patient receives more than one type of other treatment as the first course of treatment, assign the code that provides the most information about how the patient was treated and use the remarks fields to explain.
Code Other Treatment for the case example above as 2 [Other experimental therapy]. Use the remarks fields to describe the transfusions and vitamin D therapy.
Reason for No Surgery of Primary Site: Does code 2 [Contraindicated due to other conditions; autopsy only case] or code 1 [ Cancer-directed surgery not recommended] have priority when coding this field for extensive tumors not surgically treated because of existing comorbidities? See discussion.
Example:
Patient has Stage IVA carcinoma of the tongue. The physician states that patient is not felt to be a good surgical candidate secondary to multiple medical frailties. Patient is treated with beam radiation.
In this case, how do we code Reason for No Site Specific Surgery? Do we use code 2 because surgery was contraindicated due to co-existing medical conditions or do we use code 1 because the tumor is very extensive and surgery would probably not be done anyway?
SEER has not established a priority for assigning the Reason for No Surgery of Primary Site codes. Assign the code which best describes the reason surgery was not performed.
Example: Assign code 2, Contraindicated due to patient risk factors. According to the physician, this is the reason that surgery was not performed.
EOD-Size of Primary Tumor--Testis: Should this field be coded to the gross pathological size when the pathology states "tumor dimension essentially the same as testicle, but is not appropriate in this case because the infiltrate does not form a mass lesion"? See Description.
Gross describes a testicle that measures a 4cm. Path micro states "several large atypical cells...These never form a true mass. Path comment states, "tumor dimension essentially the same as testicle, but is not appropriate in this case because the infiltrate does not form a mass lesion."
For cases diagnosed 1998-2003: Code the tumor size as 999 [Not stated] for the case example above. Keep in mind that tumor size is not used in analysis for certain sites such as testis, stomach, colon & rectum, ovary, prostate, and urinary bladder. Tumor size is important for analysis for certain sites such as lung, bone, breast, and kidney.
Primary Site/EOD-Size of Primary Tumor--Lung: If the only lung mass described in CXR is a "hilar mass," is the primary site coded to C34.9 [Lung, NOS] or C34.0 [Main Bronchus; incl. Carina]? Also, can the size of the hilar mass be used to code the size of tumor field?
Because the only description available is "hilar mass," code primary site as C34.0.
For cases diagnosed 1998-2003: Use size of mass for EOD-Size of Primary Tumor.
EOD-Lymph Nodes--Colon: Are deposits of carcinoma in the pericolic fat still coded as lymph nodes when the pathology report states, "there is a high likelihood that these represent foci of venous invasion"? See Description.
Patient underwent resection for adenocarcinoma of the rectum. Path final diagnosis stated: "Regional lymph nodes: met carcinoma in 18 of
43 lymph nodes. Pathologic stage (AJCC/UICC 6th edition): pT3, V2, pN2, pMx. See comment." Path comment: "There are additional macroscopic stellate deposits of carcinoma in the pericolic soft tissue. According to the 6th edition of the AJCC staging manual, these should be designated as "V2," indicating that there is a high likelihood that these represent foci of venous invasion."
For cases diagnosed 1998-2003: Each grossly detectable nodule in the pericolonic fat is counted as one regional lymph node.
When the number of deposits is not mentioned, code Number of Regional Nodes Positive as 97 [Positive nodes but number of positive nodes not specified]. Unless the procedure is documented as a dissection, code Number of Regional Nodes Examined as 98 [Regional lymph nodes surgically removed but number of lymph nodes unknown/not stated and not documented as samping or dissection; nodes examined, but number unknown].
Primary Site--Head & Neck: What is the anatomical distinction among tonsillar fossa, tonsillar pillar, and tonsil NOS?
Operative findings describe a right tonsil three times the size of the left tonsil. Tonsil is dissected from the tonsillar fossa. There appeared to be no involvement of tumor below the tonsillar capsule.
The tonsil lies in an indentation called the tonsillar fossa. The tonsillar fossa is bordered on either side by the tonsillar pillars. The tonsillar pillars are part of the supporting structure of the throat opening.
Code C09.9 [Tonsil NOS] as the primary site for the case above.
Date of Diagnosis/Diagnostic Confirmation: How are these fields coded when a physician statement of diagnosis predates a positive biopsy? See Description.
A mass seen on EGD with negative biopsy 12/28/01. Needle core biopsies 1/14/02 were diagnostic of GIST. Gleevec treatment was initiated 2/02, and in discharge summary 5/27/02, the physician says the GIST was diagnosed on EGD.
Code the date of diagnosis as 01/2002. Code the diagnostic confirmation as positive histology. EGD revealed a "mass." Biopsies of the "mass" seen on EGD were negative before January 2002.
Histology (Pre-2007): What code is used to represent the histology "PD infiltrating duct ca with focal sarcomatoid pleomorphic features?"
For tumors diagnosed prior to 2007:
Code histology as 8500/33 [Infiltrating duct carcinoma, poorly differentiated]. "Features" is a term from the list indicating a majority of the tumor, however; in this case "features" is modified by "focal" which does not indicate a majority of the tumor.
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.
EOD-Size of Primary Tumor/First Course Treatment--Breast: How is tumor size coded when preventative tamoxifen treatment precedes breast cancer diagnosis? Can we code the tumor size from the surgical specimen? Is tamoxifen treatment here? See Description.
What is the tumor size in this situation? Patient is on the STAR trial (preventative tamoxifen for women with high risk for breast cancer). Patient develops breast cancer and has surgery.
For cases diagnosed 1998-2003: Code EOD-Size of Primary Tumor from the surgical pathology report.
Do not code this preventative tamoxifen as first course cancer-directed treatment. This tamoxifen was part of a clinical trial intending to delay or prevent beast cancer from developing.
CS Extension/Polyp--Colon: How is CS extension coded for tumor invasion described as "Haggitt level 4"? See Description.
Polypectomy specimen revealed adenocarcinoma of the rectum in a tubulovillous adenoma. Per path extent of invasion was Haggitt level 4. The micro description of the tumor stated that there was malignant epithelial neoplasm in colonic mucosa.
In a 1985 Gastroenterology journal article, Haggitt described five levels of polyp invasion:
Level 0-confined to mucosa
Level 1-head
Level 2-Neck
Level 3-Stalk
Level 4-Submucosa of underlying colonic wall.
For cases diagnosed 2004 and forward:
Use the best information available to code CS extension. The following conversion may be used when the only information available is the Haggitt level.
