Radiation: How would this field be coded for treatment with quadramet [radioactive samarium]? See Description.
Paitent is receiving quadramet for treatment of lung metastases.
Code Quadramet in the RX Summ-Radiation field as 3 [Radioisotopes]. Quadramet is a radioisotope used to palliate bone pain. The instructions in the SEER manual state: "Record all radiation that is given, even if it is palliative."
Grade, Differentiation--Bladder: How is this field coded for a five grade system? See Description.
Example: Invasive, high grade transitional cell carcinoma (Grade 4-5/5)
For this example, code grade as 4 based on the term "High grade." If "high grade" was not stated, the grade would be coded as 9, not determined. There is no SEER translation between the ICD-O grades and a five grade system for bladder. None of the pathololgist experts we querried knew of a five grade system for bladder.
Laterality--Head & Neck: Does the site code C098 need a laterality code? See Description.
In the SEER EOD-88 3rd edition, page 36, site code C098 does not need laterality. In the SEER Program code manual, 3rd edition, page 93, site code C098 is listed as a site that needs a laterality code 1-9.
Topography code C098 [Overlapping lesion of tonsil] requires a laterality code of 1-9. Follow the laterality guidelines in the SEER Program Code Manual.
Histology (Pre-2007)--Stomach: What code is used to represent the histology of "mucin-secreting adenocarcinoma, intestinal type "for a stomach primary?
For tumors diagnosed prior to 2007:
For this specific example, code histology to 8481 [Mucin-producing adenocarcinoma] as it is a more specific cell type with inherent prognostic information.
Code 8255/3 [Adenocarcinoma with mixed subtypes] is not appropriate for this case because "intestinal type" is a more specific description of this cancer and not another type of cancer. There are two broad categories of gastrointestinal adenocarcinomas: Intestinal and Diffuse.
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.
Reportability--Ovary: Is a Stage IIIC serous borderline tumor (micropapillary type) of the ovary diagnosed in 2003 reportable?
Serous borderline tumor of the ovary diagnosed in 2003 is not reportable to SEER. The behavior code is /1 in ICD-O-3. The high stage does not make this borderline tumor reportable.
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.
Surgery of Primary Site--Skin: When would one use codes 30-33 for this field on a skin primary?
Surgery of Primary Site codes 30-33 under "skin" are used for various types of biopsies followed by a gross excision of the lesion. The two procedures (biopsy and gross excision) may be performed on different days, at different facilities, by different physicians as long as both procedures are performed during the first course of treatment.
Answer applies to both pre-2002 and 2003+ surgury code definitions.
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.
Primary site/Surgery of Primary Site/Surgical Procedure of Other Site--Unknown & ill-defined site: How are these fields coded for this type of primary site when a tumor excision and lymph node dissection is performed? See Description.
Patient had a left parotidectomy w/ neck dissection in 02/2003. Findings showed a 10x5cm neck mass over the angle of the mandible as well as a 1.5 cm level 4 mass. Path showed invasive mod diff squamous cell ca. with posterior soft tissue margin positive for tumor; small portion of salivary gland had no tumor. Metastatic SCCa in 5 of 34 lymph nodes of neck dissection; no tumor in parotid lymph nodes. Pathology report says this could be a parotid carcinoma because the bulk of the disease is in the parotid, but it could also be metastatic...correlate with clinical findings. Doctor calls this unknown primary of the head and neck. Is this C80.9 or C76.0?
For cases diagnosed 1998-2003: The data item "Surgery of Primary Site" is intended to record only surgeries of the primary site. If the primary site is unknown or ill-defined, it is impossible to determine whether or not a particular surgery was performed on the primary site. "Surgical Procedure of Other Site" collects much less specific information; however, this is the correct data item to record surgery performed when the primary site is unknown or ill-defined.
For the case example, code the primary site as C76.0 [Head, face or neck, NOS]. Code Surgery of Primary Site as 98 [All unknown and ill-defined disease sites, with or without surgical treatment]. Code Surgical Procedure of Other Site as 1 [Non-primary surgical procedure performed].
EOD-Lymph Nodes/Extension: How does one code these fields if the clinical level of disease extension prior to neoadjuvant treatment is greater than demonstrated on pathology at time of resection? See discussion.
Breast case described clinically as a "breast mass and nodal metastases" which is treated with neoadjuvant chemotherapy and at surgery the lymph nodes are pathologically negative.
For cases diagnosed 1998-2003:
Use the combination of clinical and pathologic information to code EOD for primary site, extension and lymph nodes. Code the more extensive disease. If lymph nodes are positive clinically and not positive after neoadjuvant treatment, code lymph node involvement. If lymph nodes are negative clinically and positive on path, code lymph node involvement. When neoadjuvant treatment is administered because of a clinical statement of stage or involvement, code EOD based on this clinical information, even if later pathologic information would lead to a lesser EOD. General guideline number 6 (page 1 of SEER EOD-88 3rd ed.) points out that clinical information must be considered when coding EOD. However, do not code EOD based on clinical information disproved by pathologic findings in the absence of intervening treatment. The scenario above: The clinical involvement of the nodes justifies the neoadjuvant chemotherapy. Therefore, code EOD based on the clinical lymph node involvement.
