Histology: Is there any guidance on using STRATA Oncology testing (molecular tumor profiling tests), such as StrataNGS and StrataEXP, to code SSDIs, histology, etc? I do not see anything in STR, SEER Program Manual, SINQ, or CAnswerForum. We are seeing the testing with our 2021 paths.
We recommend that you do not use information from these molecular tumor profiling tests until they become a standard diagnostic tool. If/when that happens, we will add information to the various manuals.
Hormone Therapy--Breast: Should Zoladex (gosrelin) or Lupron (leuprolide acetate) be coded as treatment for breast cancer when the physician does not indicate whether or not these drugs are intended as cancer-directed therapy? See discussion.
According to an oncologist at the research hospital in our region, these drugs are given in combination with chemotherapy for two reasons:
1) To preserve ovarian function.
2) The agents may be more effective in treating breast cancer when given in conjunction with chemotherapy than with chemotherapy alone.
For cases diagnosed 1/1/2003 to 12/31/2010: Code Zoladex (gosrelin) and Lupron (leuprolide acetate) as 01 [Hormone therapy administered as first course therapy] only when stated to be given as part of the first course of cancer-directed therapy. If you do not know whether these drugs were given to preserve ovarian function or as an adjunct to chemotherapy (i.e, there is no treatment plan), do not code as Hormonal treatment given.
Hormone Therapy--Breast: How are hormone therapy (HT) and other related data items coded when a patient had a previous breast primary and is still on HT when diagnosed with a new breast primary? See Discussion.
In this scenario, we record that HT began for the second primary on the date of diagnosis, and the Systemic/Surgery Sequence ends up usually being coded 4 because the HT continues even if the specific agent may be changed. This does not seem to meet the definition of neoadjuvant therapy for the second primary so we approach the staging and grade coding as just clinical/pathological? For example, if the tumor size at surgery is a little larger than estimated on imaging, we would use the pathologic size for our staging. The tumor size and grade of the second primary are not being changed by the ongoing HT. Do we have the right approach?
For this example: 1. Code HT as treatment on the date of diagnosis for the second primary. 2. Code Systemic/Surgery Sequence as 4. 3. Do not code neoadjuvant data items as neoadjuvant started/completed. The HT given would not qualify for neoadjuvant therapy since the intent of the HT was not neoadjuvant. The HT would affect the second primary, but it is still not neoadjuvant. 4. Code clinical and pathological tumor size accordingly, based on the imaging and the pathological findings. 5. Code Extent of Disease data items based on the pathological findings since pathological findings take priority over clinical and this is not neoadjuvant therapy.
Immunotherapy/Other
Therapy--Heme & Lymphoid Neoplasms: Is the elimination of immunosuppression
treatment coded as other treatment? An example is when a post-transplant
patient develops a malignant myeloproliferative neoplasm that subsides when
immunosuppression drugs are stopped.
Do not code as a treatment. Record the cessation of
immunosuppressive drug treatment in text to explain the patient’s change in
disease status.
Immunotherapy: Is immunotherapy ever palliative treatment according to any oncologists or SEER?
Any treatment that destroys or modifies cancer tissue should be recorded as the appropriate type of treatment -- chemo, immuno, etc. Even if immunotherapy is given for symptoms/palliative treatment, it is likely to kill off tumor cells.
Laterality--Brain and CNS: Can Laterality be coded as 5 (midline) for a sella turcica meningioma (or tuberculum sellae meningioma) when no other statement regarding tumor laterality is documented? See Discussion.
Laterality is often not noted for these sella turcica meningiomas; therefore, Laterality is often coded as 9 (Unknown). Because the sella turcica appears to be a midline structure in the base of the skull, is Laterality code 5 (midline) more appropriate when additional information is unavailable?
You may assign code 5 (Paired site: midline tumor) for laterality of a meningioma of the sella turcica (C700).
The 2022 SEER manual states in Laterality coding instruction 5: Assign Laterality code 5 only when the primary site is C700, C710-C714, C722-C725, C443, C445. Do not assign code 5 to sites not listed in 5.a.
Note that code 9 is for paired sites and there is no information concerning laterality.
Document laterality information in the appropriate text field. Note: Laterality does not factor into the CNS Solid Tumor rules.
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].
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.
Laterality--Head and Neck: Were the topography codes C090 and C091 intentionally left off of the Sites for Which Laterality Codes Must Be Recorded table in the 2018 SEER Manual? The codes were also removed from Table 10 in the 2018 Solid Tumor Rules for Head and Neck but appear under coding instructions 1b. and 6b. in the manual.
Thank you for bringing this to our attention. C090 and C091 were intentionally removed from the list of sites for which laterality must be coded. They should have also been removed from coding instructions 1b and 6b. We will make that correction in the next version of the manual.
Laterality: Why is a code 5 for laterality midline only allowed for certain sites of brain and skin? I have a nasal cavity tumor and the path report specifically says "Tumor laterality: midline". What is the correct laterality code here?
Assign laterality code 9 for midline nasal cavity tumor. We will investigate this issue further.
