Reportability/Primary Site--Lip: Is a right lower lip (NOS) squamous cell carcinoma reportable when the microscopic description states the tumor arises from the epidermis and extends through the dermis? See discussion.
We are having difficulty determining whether the primary site is lip, NOS (C009) or skin of lip (C440). Usually we look for a statement of “skin” or “mucosa” in the microscopic description if the specimen label is only lip, NOS as instructed by the previous SINQ 20051049. Is a statement of "epidermis" or "dermis" in the microscopic description enough to indicate carcinoma is arising in the skin of the lip (C440) and thus not reportable?
This case is interpreted as skin of lip and not reportable. According to our expert pathologist consultant, the pathologist in this case "is specifically saying "epidermis" and "dermis" and I would have to think it is skin, and thus not reportable."
Reportability: Is positive urine cytology (ex: malignant cells interpreted as carcinoma) by itself reportable? If so, is the case coded to bladder by default or is is coded to C689, urinary system, NOS?
Urine cytology positive for malignancy is reportable. Code the primary site to C689 in the absence of any other information.
However, if a subsequent biopsy of a urinary site is negative, do not report the case.
For 2013 diagnoses and forward, report these cases when they are encountered. Do not implement new/additional casefinding methods to capture these cases.
As always, do not report cytology cases with ambiguous terminology.
EOD-Size of Primary Tumor: How is tumor size coded when there is a clinical tumor size, the excisional biopsy pathology report has a tumor size and the resection specimen has residual tumor, but there is no tumor size provided in the pathology report?
For cases diagnosed 1998-2003: Code the EOD-Size of Primary Tumor from the excisional biopsy. If there is some indication that a large amount of tumor was removed at the time of the resection, code the clinical size instead. When both an excisional biopsy and a resection show tumor, code the largest size of tumor reported.
Grade: Can the FIGO grade be used to code the morphologic grade? See discussion.
FIGO Grade is coded in CS SSF 7 in the Corpus Uteri schema. The SEER Manual does not address using FIGO grade for coding grade in morphology.
Do not use FIGO grade to code the grade field. See the sentence below the table in Instruction #6 in the Grade Coding Instructions for cases diagnosed 2014 and later, http://seer.cancer.gov/tools/grade/
MP/H Rules/Histology: What is the correct histology code for a NUT midline carcinoma?
Code histology to 8010/3.
NUT carcinoma is identified by the NUTM1 gene rearrangement.
NUT midline carcinomas (NMC) are lethal and morphologically indistinguishable from other poorly diff carcinomas. They are epithelial tumors which can range from undifferentiated carcinomas to carcinomas with prominent squamous differentiation.
A new proposed ICD-O-3 code has been suggested for NUT tumors but it is not yet approved for implementation. Do not use the new code until it is approved for use in the United States.
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.
MPH rules--Rectum: How is the number of primaries to be determined when a treatment plan has been completed, but it is not possible to determine whether there was a disease-free interval between occurrences? See Discussion.
Patient diagnosed with adenocarcinoma of the rectum in March 2006, underwent chemo and radiation therapy as treatment. Patient seen in April 2007 for surveillance colonoscopy. HPI stated patient underwent chemorad with good results. Colonoscopy showed "persistent" disease. Abdominal perineal resection was done in May 2007. Path showed adenocarcinoma of the rectum.
Keeping in mind that we are not to use a clinical statement for determining recurrences, is the April 2007 occurrence counted as a new primary?
For cases diagnosed 2007 or later:
Do not abstract the 2007 events as a new primary. "Persistent disease" indicates there was never a disease free interval.
Multiplicity Counter/Ambiguous terminology: How should these fields be coded for cases with an unknown date of diagnosis?
If the date of diagnosis is unknown, it is likely that you have little information for this case. Both multiplicity counter and ambiguous terminology fields would probably be coded as unknown. However, if information on the number of tumors and the diagnostic confirmation are available, code these fields as specified in the manual.
Systemic/Surgery Sequence: The note associated with code 4 in Systemic Treatment/Surgery Sequence in the 2018 SEER Manual says: Code 4 is intended for situations with at least two episodes or courses of systemic therapy. Does this mean two different types of systemic therapy before and after surgery? See Discussion.
For example, chemotherapy and immunotherapy administered first, followed by surgery, then immunotherapy and hormone therapy after surgery. Or is code 4 used for two administrations of chemotherapy before surgery and two more courses after surgery?
Assign code 4 for the example you describe. Code 4 also applies to cases with one course of chemotherapy before surgery and another course after surgery.
EOD 2018/EOD Primary Tumor/Neoadjuvant treatment: If there is no clinical information available and all that is available is the post-neoadjuvant information, is it better to code EOD unknown (999) or use the post-neoadjuvant information to code EOD? See Discussion.
The Extent of Disease (EOD) Manual states: Neoadjuvant (preoperative) therapy: If the patient receives neoadjuvant (preoperative) systemic therapy (chemotherapy, immunotherapy) or radiation therapy, code the clinical information if that is the farthest extension documented. If the post-neoadjuvant surgery shows more extensive disease, code the extension based on the post-neoadjuvant information.
Code EOD Primary Tumor using the post neoadjuvant information for this case. Since the only information you have is the post neoadjuvant, code that. EOD combines clinical and pathological information.
