First Course Treatment/Reportability: Are there situations for which a case with a class-of-case code in the 30's should be reported to the central registry? We know these are not reportable to the CoC, but should they be reported to the central registry? See Discussion.

Example: 3/22/2017-26 year old white female seen in the emergency room with abdominal pain. Patient was diagnosed about a month ago with breast cancer. Impression: menstrual pain. In this example the patient is newly diagnosed with breast cancer, but the second hospital does not treat or diagnose the patient; pain management for a separate condition is received only. Is this patient reported due to the history of active disease?

Work with your central registry to determine which cases they require you to report. In general, any case still undergoing first course of treatment, even if not given at your facility, should be reported to the central registry. Many central registries will appreciate knowing that the patient was seen at your facility to update date last seen and other data items.

First Course Treatment/Scope of Regional Lymph Node Surgery--Breast:  How is Scope of Regional Lymph Node Surgery coded when initially there is a sentinel lymph node biopsy (SLNBx) and an intramammary node removed followed a month later by an axillary dissection for a right breast primary? See Discussion.

Patient has a diagnosis of invasive carcinoma of the right breast from a core biopsy on 04/2023.

Subsequent bilateral mastectomy and sentinel node biopsy proves one positive sentinel node and one negative intramammary node.

One month later there is a completion axillary node dissection with 15 nodes negative for malignancy.

Per previous SINQ 20190074, the initial mastectomy and sentinel node excision with intramammary node removal should be coded as Scope of Regional Lymph Node Surgery 6. It is unclear how the resulting axillary dissection should be recorded in Scope of Regional Lymph Node Surgery. There is no code for sentinel node biopsy and 3, 4, or 5 at same time (code 6) PLUS an additional subsequent axillary dissection.

Please provide coding instructions for Sentinel Lymph Nodes Positive, Sentinel Lymph Nodes Examined, and Scope of Regional Lymph Node Surgery in this scenario.

Scope of Regional Lymph Node Surgery:  Assign code 7, Sentinel node biopsy and code 3, 4, or 5 at different times. In this case, the SLNBx (code 2) preceded the regional node dissection (code 5: 4 or more regional lymph nodes removed), i.e., procedures performed in separate surgical events.

Sentinel Lymph Nodes Examined:  Assign code 98, Sentinel lymph nodes were biopsied, but the number is unknown. In this case, only the results were provided.

Sentinel Lymph Nodes Positive:  Assign code 01, Sentinel nodes are positive (code exact number of nodes positive). In this case, there was one positive sentinel node.

First Course Treatment/Surgery of Primary Site--Breast: How is "Goldilocks," also referred to as oncoplastic reconstruction, in the surgery section for breast cancer patients coded?

Code Goldilocks mastectomy in Surgery of Primary Site. Breast surgery code 30 seems to be the best available choice for "Goldilocks" mastectomy. It is essentially a skin-sparing mastectomy with breast reconstruction. The choice between code 30 and codes in the 40-49 range depends on the extent of the breast removal. Review the operative report carefully and assign the code the best reflects the extent of the breast removal.

First Course Treatment/Surgery of Primary Site--Liver/Intrahepatic Bile Ducts: For a liver/intrahepatic bile duct primary, is an alcohol embolization the same thing as a percutaneous ethanol injection (PEI)?  See Discussion.

For C220-C221 primaries, Surgery of Primary Site includes code A150 for Alcohol tumor destruction (percutaneous ethanol injection/intratumoral injection of alcohol/alcohol ablation). The SEER and STORE manuals also indicate that alcohol embolization should be coded as Other Therapy, code 1. We are trying to determine whether alcohol embolization should be coded under Surgery of Primary Site or Other Therapy.

Code alcohol ablation under Surgery of Primary Site 2023. Code alcohol embolization as Other Therapy when tumor embolization is performed using alcohol as the embolizing agent.

Alcohol ablation, also known as an ultrasound-guided percutaneous ethanol injection (PEI); is treatment that involves injecting concentrated alcohol directly into the tumor. Embolization uses special techniques to close off blood flow by introducing special medications or using other techniques designed to block blood vessels. Types of embolization are arterial embolization as with alcohol (ethanol), chemoembolization, and radioembolization. Refer to the current SEER Program Coding and Staging Manual when assigning surgery and embolization procedures.

First Course Treatment/Surgery of Primary Site--Rectum:  What surgery code should be used for laparoscopic C/T open low anterior resection with colorectal anastomosis, loop ileostomy in diagnosis year 2020, code 30 or 40?  See Discussion.

Can you provide clarification on Rectum primary surgical code 40 Pull through WITH sphincter preservation (colo-anal anastomosis)? Would this be code 30 or 40 due to the colorectal anastomosis? 

Assign code 40, Pull through WITH sphincter preservation (colo-anal anastomosis).  The National Cancer Institute Dictionary of Cancer Terms defines coloanal anastomosis as a surgical procedure in which the colon is attached to the anus after the rectum has been removed. It is also called coloanal pull-through.

First Course Treatment/Surgical Margins of the Primary Site--Melanoma: Is margin status positive or negative when the lesion “approximates” margins? This was noted in the pathology report comment on a malignant melanoma in-situ shave biopsy.  Follow-up with physicians is not possible in this situation.

Assign margin status as “positive” when stated as approximates margins as recommended by our expert pathologists. Approximating means coming right up to inked margin without the margin transecting the tumor.

First Course Treatment: 1) When is Decadron (Dexamethasone) coded as cancer treatment? 2) When Decadron is given to a patient with multiple myeloma, is it coded as treatment only if given in combination with chemotherapy? See discussion.

SEER Book 8 states that Decadron is an important therapeutic agent for treatment of multiple myeloma. In the Abstracting and Coding Guide for the Hematopoietic Diseases, Decadron is a hormonal treatment for multiple myeloma "when given as part of a chemotherapy regimen".

For cases diagnosed 1/1/2003 and after:

1. Code hormone therapy to 01. Code any therapy administered to treat cancer tissue that achieves its effect on cancer tissue through a change in the hormone balance in the hormone therapy field. Decadron is coded for leukemias, lymphomas and multiple myelomas primaries. It is coded for other sites only when stated to be cancer-directed treatment.

2. Code hormone therapy to 01. Decadron should be coded as hormone therapy for multiple myeloma when given alone or as part of a first course of treatment chemotherapy regimen.

First Course Treatment: If an "aromatase inhibitor" used as a complement to Tamoxifen is treatment, how should it be coded?

When an aromatase inhibitor is part of the planned first course of therapy, code it under hormone treatment.

When a change of drug is PLANNED, it is part of the same course even if subcategories change. This is the usual situation with Tamoxifen and aromatase inhibitor (for example: Femara). The switch to Femara is planned, so it is not a new course. When a drug change happens that is not planned, it is still the same course if both drugs are in the same category and subcategory. An unplanned drug change to a different subcategory would be a new course.

First Course Treatment: If the patient receives no treatment at the time of diagnosis (either because it is not recommended or because the patient refused treatment at that time) but treatment is later instituted after disease progression, should this treatment be coded as part of the first course of treatment?

The SEER rules changed in 1998 regarding what constitutes First Course of Cancer-Directed Therapy.

For cases diagnosed on or after 1/1/98: The First Course of Cancer-Directed Therapy fields will all be coded to 0 [None] for these types of cases. The documented disease progression would stop the timeframe for inclusion of any treatment to be part of first course of therapy.

First Course Treatment: Should the definition in the 2016 SEER Coding Manual be revised for first course of treatment following disease progression for patients who complete the initial first course treatment plan without alteration but had one or more treatment modalities given after disease progression was identified? See Discussion.

The FORDS Manual (pg. 22) states: The first course of treatment includes all methods of treatment recorded in the treatment plan and administered to the patient before disease progression or recurrence. The instructions in the FORDS Manual and clarification from multiple CAnswer Forum posts indicates the planned first course treatment stops following disease progression, even when the first course treatment plan is not altered or changed.

SEER, on the other hand, instructs registrars to do the opposite. The SEER Manual instructs registrars to code all completed treatment given as part of the initial first course treatment plan, even after disease progression, provided the treatment plan is not changed or altered. (See 2016 SEER Manual, Section VII First Course of Therapy, Treatment Timing, Rule 1 and Example 1.)

For consistency in data collection, shouldnt the standard setters use the same guidelines to define first course treatment? Given that the majority of cases are reported to SEER by registrars in CoC facilities, who may not be abstracting treatment modalities that occur after progression, the SEER expectation is likely not able to be performed consistently. Wont this difference in standard setter data collection expectations negatively impact the treatment data reflected on our files?

The example cited above will not be included in the 2018 edition of the SEER manual. Removing this example will improve the consistency in recording first course of treatment for cases diagnosed 2018 and later.
