Report Question ID Question Discussion Answer Year
20041011 EOD-Clinical Extension--Prostate: Should this field be coded to 15 [Tumor identified by needle biopsy for elevated PSA] or 30 [Localized, NOS] when the only information is from a biopsy positive pathology report that includes the clinical history of "PSA elevated, DRE negative," with no mention of an ultrasound being performed?

For cases diagnosed 1998-2003: For this scenario, assign code 15 if an ultrasound was not performed, performed and negative, or when it is unknown whether or not an ultrasound was performed. Assign code 30 only if an ultrasound was performed and there is no documentation stating that it was negative or positive.

Please refer to the Prostate EOD Coding Guidelines for all of the instructions pertaining to the coding of prostate EOD.

20031043 EOD-Extension--Corpus Uteri: How is this field coded for a stage III A endometrial primary with positive pelvic washings, involvement of the omental serosa, and negative lymph nodes? For cases diagnosed 1998-2003: Code EOD-extension as 85 [Metastasis]. According to our TNM consultant, Omental metastasis is M1, Stage IVB [EOD 85]. 2003
20091064 Radiation Sequence with Surgery--Head & Neck: How is this field coded for a tonsil primary diagnosed on 4/16/07 by a regional lymph node FNA when the patient subsequently initiates radiation on 5/8/07 and has a tonsillectomy with neck dissection on 7/30/07? The best way to handle this situation is to assign code 2 [Radiation before surgery] in Radiation Sequence with Surgery. Code 2 provides the best description of the sequence of events in this case. Radiation was delivered prior to the resection of the primary site. 2009

MP/H Rules/Multiple primaries--Breast: Is this the same primary per MP/H Rule M10? Ductal carcinoma of the left breast in 2013, treated with a lumpectomy. New tumor with ductal and lobular carcinoma in the same breast in 2016.

The 2016 diagnosis is the same primary. MP/H Rule M10 for breast cancer applies. Do not change the original histology code. Use text fields to document the later histologic type -- duct and lobular.

Surgery of Primary Site--Melanoma: Please further explain the SEER Note under Melanoma surgery codes 30-36 for these two examples. Are both examples coded 31?

1. Shave bx: +melanoma in situ, +microscopic margins  Wide excision: no residual melanoma in situ

2. Shave bx: melanoma, +microscopic margin   Wide excision: Melanoma, margins negative (margin status negative but distance not stated)

Revised answer: Assign surgery code 30 for both examples based on the SEER Note on the top of page 2 in the Surgery of Primary Site Codes for Skin: If it is stated to be a wide excision or reexcision, but the margins are unknown, code to 30.

20000259 Histology (Pre-2007): What code is used to represent the histology for a "malignant invasive gastrointestinal stromal tumor (GIST)"?

For tumors diagnosed 2001-2006: Malignant GIST is coded 8936/3.

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.

Seq no-central--Brain and CNS: How should subsequent tumors be sequenced when the patient has a history of a brain tumor, with no information on the behavior of the brain tumor? According to the sequencing rules, it appears some assumption must be made regarding the behavior of the brain tumor.

Sequence the brain tumor in the 60-87 series when you do not know the behavior. If you have reason to believe the brain tumor was malignant, sequence it in the 00-59 series.

2015
20000495 EOD Fields--All Sites: Is EOD information limited to what is available exactly two months from the day of diagnosis?

For cases diagnosed 1998-2003:

EOD should include all information available within four months of diagnosis in the absence of disease progression or through completion of surgery(ies) in first course of treatment, whichever is longer.

Mets known to have developed after EOD was established should be excluded.

Reportability--Skin: Is early/evolving lentigo maligna reportable?

As of 01/01/2021, early or evolving melanoma in situ, or any other early or evolving melanoma, is reportable.

20160077

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.
