First Course of Therapy/Hormone Therapy--Thyroid: Is Thyrogen (thyrotropin alpha) coded as hormone therapy when a patient is given Thyrogen as part of planned 2-day Thyrogen Stimulated I-131 treatment for a papillary or follicular cancer? See Discussion.

SEER*Rx categorizes Thyrogen as Hormones and hormonal mechanisms/Thyroid stimulating hormone. Probably not cancer directed–verify with attending MD.

Do not code Thyrogen as hormone therapy when given as a stimulating agent in I-131 therapy. The therapeutic agent is I-131.

The Thyrogen/thyroid stimulating hormone (TSH) is sensitizing the gland to absorb more I-131. Thyrogen/TSH is a trophic hormone so it can cause growth of cancer cells. Thyroid hormones are given in follicular and papillary thyroid cancers to suppress TSH. Although Thyrogen can promote cancer growth its use in Thyrogen stimulated I-131 radioactive therapy is justified (benefits exceed the risk), since the use is short (2 days) and the high amount of I-131 would kill cancer cells in addition to majority of thyroid tissue.

We will update the Thyrogen entry in SEER*Rx and clarify in the next release of the SEER manual, Appendix C Coding Guidelines for Thyroid.

First course of treatment--Immunotherapy:  Should Rituxan be coded to immunotherapy?  See discussion.

Is the instruction under #4.b. on page 114 of the 2014 SEER Program Coding and Staging Manual incorrect? It says to code Rituxan as chemotherapy.  

Rituxan changed categories from chemotherapy to a biologic therapy/Immunotherapy agent effective with cases diagnosed January 1, 2013. See page 150 or page 164 in the 2015 SEER manual. The instruction in the 2014 SEER manual was incorrect regarding Rituxan.

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.

First Course of Treatment/Other Therapy: Where do you code Optune TTF therapy? What needs to be included in the text portion to document this treatment?

Code OPTUNE in the Other Treatment field. See NovaTTF in SEER*Rx (http://seer.cancer.gov/seertools/seerrx/). NovaTTF is the pre-FDA approval name for OPTUNE.

If OPTUNE was administered for recurrence, be sure NOT to record it in the first course of treatment fields. Check with CoC if you have questions about coding treatment for recurrence.

First course of treatment/Radiation therapy--Kidney: Patient has a CT-guided biopsy of a right renal mass with procedure details under the Interventional Radiology Procedure Note stating "Gelfoam tract embolization." Is this particular embolization treatment?

Gelfoam tract embolization for a CT-guided renal biopsy is not treatment. It is a method to plug the biopsy track to reduce the risk of hemorrhage.

First Course of Treatment/Surgery of Primary Site--Corpus uteri: Do you code total hysterectomy or radical hysterectomy when a specimen indicates the uterus, cervix, ovaries, fallopian tubes, and right and left parametrium were resected, but shows no portion of the vagina. See Discussion.

AFS1-AFS2-frozen section control, endomyometrium; AFS3-frozen section control, subserosal intramural mass; A4-anterior cervix; A5-posterior cervix; A6-anterior cervical endometrial junction; A7-posterior cervical endometrial junction; A8-A10-anterior endomyometrium, including tumor; A11-A13-posterior endomyometrium, including tumor and adjacent mass; A14-random section subserosal mass; A15-left parametrium at margin of resection; A16-right parametrium at margin of resection; A17-A18-left ovary and fallopian tube; A19-A20-right ovary and fallopian tube. The final diagnosis includes Endometrial adenocarcinoma, favor serous carcinoma, with papillary and solid areas. Tumor involves: Cervix present, Right ovary, Left ovary, Right fallopian tube, Left fallopian tube, Right parametrium, Left parametrium.

Assign code 50 for total hysterectomy. According to Appendix C Surgery Codes for Corpus Uteri of the 2016 SEER Coding and Staging Manual, total hysterectomy is surgery to remove the entire uterus, including the cervix; whereas, radical hysterectomy includes the vagina.

First Course of Treatment/Surgery of Primary Site--Melanoma: How do you code UVB therapy treatment for melanoma?

Code UVB therapy for melanoma as photodynamic therapy under Surgery of Primary Site for skin. Assign code 11 [Photodynamic therapy (PDT)] if there is no pathology specimen. Assign code 21 [Photodynamic therapy (PDT)] if there is a pathology specimen. Use text fields to document details.

First course of treatment: What is the correct code to use for allogenic stem cell transplant?

Code an allogenic stem cell transplant as 20 (Stem cell harvest (stem cell transplant) and infusion) in Hematologic Transplant and Endocrine Procedures in the 2016 SEER Manual.

First course teatment/Surgery of Primary Site: Is microwave ablation (using heat not alcohol) coded to a surgery code? See Discussion.

As of 2013, radiofrequency ablation is coded to "radiation therapy," chemoembolization is coded to "chemotherapy," and microwave ablation code to "other."  Or, is coding microwave ablation (using heat not alcohol) coded to surgical code "16"? The latest documentation year that I could find in the SEER website regarding the above was 2013. I would appreciate clarification/confirmation of correct coding especially for microwave ablation.

According to a consensus answer of the technical advisory group, a small group of representatives from each standard setter that meets periodically, microwave tumor ablation should be coded as surgery.  For liver, assign code 16 (Heat-Radio-Frequency ablation (RFA); for kidney, assign code 15 (Thermal ablation).

First Course Therapy/Neoadjuvant Treatment:  How are Neoadjuvant Therapy--Clinical Response and Neoadjuvant Therapy--Treatment Effect coded when the neoadjuvant therapy was not completed? Does the entire course of neoadjuvant therapy need to be completed before we can code these fields? See Discussion.

Example: The neoadjuvant therapy was started, the patient progressed, the treatment plan was altered, and a new course of systemic therapy was started; surgery was cancelled.

01/25/21 Bile duct brushing: Malignant cells present, adenocarcinoma

01/26/21 Surgical oncology consult: Currently unresectable; recommend neoadjuvant chemo

02/22/21-3/29/21 Neoadjuvant Gemzar & Abraxane, two cycles, discontinued due to disease progression

04/17/21 Surgical oncology re-eval: CT positive for disease progression, need to change Rx

04/26/21 Second change of treatment due to progression: Irinotecan, Oxaliplatin, and 5FU

07/16/21 Surgical oncology re-eval: Unresectable, advise 4-6 months of chemo followed by radiation

Assign code 3 (Progressive disease (PD)(per managing/treating physician statement) for Neoadjuvant Treatment--Clinical Response and code 7 (Neoadjuvant therapy completed and planned surgical resection not performed) for Neoadjuvant Treatment--Treatment Effect. These are the best choices under the circumstances. Use text fields to record the details.
