First course treatment/Immunotherapy--Prostate: Is XGEVA, given for bone mets from prostate cancer, abstracted as immunotherapy, or is it an ancillary drug and not recorded?
Do not record XGEVA when given for bone mets from prostate cancer. See SEER*Rx for more information.
Grade--Kidney: Should WHO/ISUP grade for renal cell carcinoma be coded for cases diagnosed 2016 and later? See discussion.
The 2016 WHO Classification of Tumours of the Urinary System appears to be moving away from using Fuhrman grading toward using WHO/ISUP grade. These seem like similar 4 grade staging systems; however, the SEER Manual specifically states to not use the Special Grade System table for WHO/ISUP. We are seeing the WHO/ISUP grade being used on 2016 pathology reports.
Examples of new grading for renal cell carcinomas
Histologic type: Clear cell renal cell carcinoma
Histologic grade (WHO/ISUP 2016): Grade 3 in a background of 2 (of 4).
And
Histologic type: Clear cell renal cell carcinoma
Histologic grade (ISUP): Grade 2.
Do not record WHO/ISUP grade in the grade/differentiation field.
Designated fields for this grade system are being proposed for future implementation.
First Course of Treatment/Hormone Therapy--Breast: Is hormone therapy (HT) prescribed for invasive ductal carcinoma of the right breast coded as treatment for lobular carcinoma in situ (LCIS) of the left breast even though the treatment plan for the LCIS was documented as surveillance? See Discussion.
Patient is diagnosed with invasive ductal carcinoma (IDC), right breast, receives HT, radiation therapy, and surgery. The same patient is diagnosed with LCIS, left breast one month later--recommend surveillance only (no surgery). Is the HT for the left breast coded at all? I think for COC/NCCN, we do not, but for SEER what would I do? Treatment in the SEER Manual 2018 states, "Code the treatment on each abstract when a patient has multiple primaries and the treatment given for one primary also affects/treats another primary." The example include bladder/prostate and ovarian/cervix. It also states, "Code the treatments only for the site that is affected when a patient has multiple primaries and the treatment affects only one of the primaries." The example includes colon/tonsil. Breast LCIS treatment appears complicated. Per NCCN guidelines, this condition no longer has recommendations, however it appears as though they still state that if a core biopsy is done and is LCIS, follow up should be ultrasound or surgical excision. Nowhere does it state hormone is recommended.
Do not code the hormone treatment for the LCIS since it was clearly documented that the hormone treatment was given for the IDC and the treatment for the LCIS was documented as "surveillance." Use text fields to record the details on both abstracts.
Grade, Differentiation: Is grade always coded to 4 for a diagnosis of Ewing's sarcoma?
Do not code the ICD-O-3 grade for Ewing sarcoma unless documented in the record.
In the TNM system, grade is required to place Ewing sarcoma into a stage group. For TNM staging purposes, Ewing sarcoma is classified as G4. Do not apply TNM rules to ICD-O coding.
Size of tumor--Breast: Please clarify guideline #7 if the only size you have is from a CORE biopsy specimen and imaging only states nonspecific sizes, like "architectural distortion" or "calcifications" and a core biopsy pathology reports invasive tumor spans 5mm. Do you use the core biopsy size, or use 999 for clinical tumor size? See discussion.
SEER Program Coding and Staging Manual 2016 states: Record size in specified order using a. The largest measurement of the primary tumor from physical exam, imaging, or other diagnostic procedures before any form of treatment. See Coding Instructions 7-9 below. b. The largest size from all information available within four months of the date of diagnosis, in the absence of disease progression when no treatment is administered. #7 Priority of imaging/radiographic techniques: Information on size from imaging/radiographic techniques can be used to code clinical size when there is no more specific size information from a biopsy or operative (surgical exploration) report. It should be taken as a lower priority, but over a physical exam.
Do not code size of tumor based on the size of the core biopsy. If the statement "invasive tumor spans 5mm" from the core biopsy report represents the surgeon's assessment of tumor size, use this information to code tumor size when no other information is available.
Chemotherapy: Should radiosensitizing chemotherapy agents (i.e., drugs typically coded as treatment for cancer) be coded as treatment when they are given in combination with radiation therapy with the intention of enhancing that treatment? See discussion.
Per our consultant, these drugs are given at a lower dose than that typically given to treat cancer patients.
Do not code radiosensitizers and radioprotectants as cancer-directed therapy. Drugs typically classified as chemotherapy agents would be "ancillary drugs" for the purpose of coding cancer-directed therapy because the drugs are given at a much lower dosage than that typically given to treat cancer patients. Per Book 8, ancillary drugs are not to be coded as cancer-directed therapy. Radiosensitizers and radioprotectants do not work directly on the cancer and are not coded under any of the systemic therapy fields.
First course treatment/Radiation Therapy--Prostate: How do you code fiducial markers for prostate cases?
Do not code fiducial markers as a form of radiation treatment; rather, code the radiation therapy in the radiation treatment section. Fiducial markers are small metal spheres, coils, or cylinders that are placed in or near a tumor to help guide the placement of radiation beams during treatment.
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.
Other Cancer Directed Therapy--Hematopoietic, NOS: Is "aspirin" treatment for primary polycythemia? See discussion.
Aspirin is listed as treatment for "thrombocythemia" in the Abstracting and Coding Guide for the Hematopoietic Diseases but not for "primary polycythemia."
Do not code aspirin as treatment for primary polycythemia (polycythemia vera).
First course of treatment/Other therapy--How do you code medical marijuana when given as "treatment?" See Discussion.
The patient has gastric cancer and the physician prescribed medical marijuana as treatment. SEER*Rx says marijuana is ancillary as a psychoactive cannabinoid and antiemetic and advises not to code it. The physician specifically wrote "treatment with" in the record. Should it be coded as Other (Code 1) under Other Therapy?
Do not code as treatment. Enter the information regarding the use of marijuana in a text field. There have been some early clinical trials of cannabinoids in treating cancer in humans and more studies are planned. While the studies so far have shown that cannabinoids can be safe in treating cancer, they do not show that they help control or cure the disease. At this time, marijuana is used to treat side-effects (such as nausea, vomiting, and pain) and to help increase appetite which helps patients tolerate standard therapies.
