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 Extension--Lung: Do we ignore pericardial effusion seen on a CXR if a subsequent lobectomy reveals only a localized tumor? See discussion.
Note 6 in the lung EOD scheme instructs us to assume that a pleural effusion is negative if a resection is done. Does this also apply to a pericardial effusion? For example, if a pericardial effusion is seen on CXR, and a subsequent lobectomy reveals only a localized tumor, should the effusion be ignored?
For cases diagnosed 1998-2003: Ignore pericardial effusion which is negative for tumor. Assume that a pericardial effusion is negative if a resection is done and the tumor is pathologically confirmed to be localized.
Histology (Pre-2007)--Colon: What code is used to represent the histology "Adenocarcinoma, intestinal type?" See Description.
The code 8144/3 is not valid for colon primaries. Should we code these as 8140/3 [Adenocarcinoma, NOS] or over-ride the error message?
For tumors diagnosed prior to 2007:
Code adenocarcinoma, intestinal type of the colon 8140 [Adenocarcinoma, NOS]. Do not use code 8144 for intestinal type adenocarcinoma in the colon.
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-Extension--Colon: How should this field be coded for "adenocarcinoma penetrating through bowel wall into adjacent adipose tissue?
For cases diagnosed 1998-2003: The difference between EOD-extension codes 40 and 45 is the level of the fat involved. Code 40 is subserosal fat immediately adjacent to the muscular wall of the colon inside the serosa/visceral peritoneum. Code 45 is pericolic fat in areas where there is a serosal surface or in the retroperitoneal areas of the ascending and descending colon where there is no serosa. Code 42 was added for use when it is not possible to determine whether subserosal fat or pericolic fat is involved. Code 42 should be used only when there is a reference to 'fat' (NOS) The answer for the case example above depends on the location of the primary and whether the fat referred to is within or outside the entire thickness of the colon wall. If no additional information is available, use code 42 [Fat, NOS].
Surgery of Primary Site--Lung: Is a core-out of the main bronchus coded in this field? See Description.
Patient with right lung cancer was not a surgical candidate because of extent of disease. Prior to receiving radiation, patient underwent bronchoscopy, which revealed obstruction from right main bronchial tumor. Core-out of the tumor was undertaken, and a specimen was sent for path evaluation. The physician stated that this was a palliative procedure to relieve obstruction.
Do not code bronchoscopy to clear the airway as surgery of primary site. When combined with laser therapy, cryosurgery, or other tumor destruction, or when combined with excision of tumor, code as surgery of primary site.
For cases diagnosed 1998-2003: Code surgery of primary site for the case described above to 23 [Excision, NOS]. Tissue was excised and sent to pathology.
Ambiguous Terminology/Histology (Pre-2007): How do we code histology when there is a difference between the histology mentioned on a suspicious cytology and the clinical diagnosis by the treating physician? See Description.
An FNA of pancreas is stated as "highly atypical cells present, suspicious for pancreatic ductal carcinoma." The attending physician states the patient has pancreatic carcinoma. Can histology be coded 8500/3 [infiltrating duct carcinoma, NOS] or should it be 8010/3 [carcinoma, NOS]?
For tumors diagnosed prior to 2007:
Code the histology from a suspicious cytology when this histology is supported by the clinical diagnosis.
Code the example above to 8010/3 [Carcinoma, NOS].
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: Pathologist states that the size of the tumor is difficult to measure but is greater than 3cm but less than 5cm. How would we code the tumor size?
For cases diagnosed 1998-2003:
Code the largest dimension mentioned, since that is the standard rule for coding tumor size. Keep in mind that tumor size is not used in analysis for certain sites such as stomach, colon & rectum, ovary, prostate, and urinary bladder. Tumor size is important for analysis for certain sites such as lung, bone, breast, and kidney.
Terms of involvement--Lung: Is "intense uptake" described on a PET scan an indication of involvement? See Description.
We are seeing increasing use of PET scans as diagnostic tools for cancer. PET scans use different terminology than the ambiguous terms listed in the EOD manual. Could we please have guidelines for interpreting PET scans?
Example: Patient with right lung cancer. PET scan showed intense uptake in the mediastinum and in the hilum. Can we code "intense uptake" as involvement of mediastinal and hilar lymph nodes?
Do not interpret "intense uptake" as involvement. Look for a statement of involvement or other terminology, such as "highly suspicious," "strongly suspicious for" malignancy, involvement, etc.
Multiple Primaries (Pre-2007)/Histology (Pre-2007)--Breast: Would the simultaneously occurring histologies of "high grade ductal carcinoma in situ with micro invasion" and "keratinizing squamous cell carcinoma" be coded as two primaries or as a single primary when the pathologist is not clear whether two separate tumor masses exist?
For tumors diagnosed prior to 2007:
Code as two primaries, assuming the tumors are separate and the margins are clear/negative. Code 8071/3 [Invasive squamous cell ca, keratinizing] and 8500/3 [Ductal carcinoma, "microinvasive"].
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.
First-Course of Cancer-Directed Therapy Fields/Hematopoietic, NOS: How do you code treatment for a myelodysplastic syndrome when a patient is admitted to receive a "second transfusion 7 months after diagnosis"?
The first course of treatment for these hematopoietic primaries lasts until there is a treatment change. For the case you cite the second transfusion (7 months after diagnosis) would be first course treatment. Code the Other Cancer-Directed Therapy Field to 1 [Other cancer-directed therapy].
