EOD 2018/EOD Regional Nodes--Oropharynx: Is code 550 missing “< equal to 6 cm” in the data item EOD Regional Nodes for Oropharynx HPV-Associated, Version 9? Otherwise, bilateral or contralateral lymph nodes with extranodal extension (ENE) that are >6 cm could fit into 550 OR 650.
Code 550 is missing “< equal to 6 cm.” In addition, code 650 should include ipsilateral lymph nodes as well.
Revised codes:
Code 550
CLINICAL ASSESSMENT only
Bilateral or contralateral lymph nodes, < equal to 6 cm WITH clinical evidence of ENE
Code 650
CLINICAL ASSESSMENT only
Ipsilateral, Bilateral or Contralateral lymph nodes > 6 cm WITH or WITHOUT clinical evidence of ENE
These changes will be implemented in Version 3.4 (October 2026). We apologize for the error.
Hematologic Transplant and Endocrine Procedures--Breast: Is a bone marrow transplant first course of cancer-directed therapy for breast cancer? If yes, are time guidelines relating to the first "remission" the same as for those used in leukemia primaries?
For cases diagnosed 1/1/2003 and after: A bone marrow transplant can be first course of therapy for cases in which there has been no progression of disease between the initial therapy (e.g., surgery, radiation, chemotherapy) and the bone marrow transplant. Code Hematologic Transplant and Endocrine Procedures field to 10-12 or 40 (depending on the type of bone marrow transplant performed).
Do not use leukemia treatment time guidelines when coding breast cancer treatment.
First course treatment/Chemotherapy: Is metronomic chemotherapy coded as chemotherapy?
Code metronomic chemotherapy as chemotherapy. Metronomic chemotherapy, also referred to as low-dose metronomic (LDM) chemotherapy, is an emerging cancer treatment approach which administers relatively low doses of traditional chemotherapy drugs over a long period of time and without ‘breaks’ in treatment. By using lower doses this method of treatment minimizes the side effects of traditional chemotherapy.
Date of Diagnosis/Ambiguous Terminology--Lung: Would the date of a PET scan that states there is a mass in the lung which is "in the range of malignancy " be coded as the date of diagnosis or would the date of a subsequent bronchoscopy with biopsy be used for diagnosis date because it confirms a malignancy?
The date of diagnosis in this case is the date of the bronchoscopy with biopsy.
"In the range of malignancy" is not one of the ambiguous terms that are reportable. Please see the list of reportable ambiguous terms on page 3 of the 2004 SEER manual. Do not accession cases based on ambiguous terms not found on the reportable list.
Birthplace/Place of birth, country: For patients originally born in a country that is currently listed as "historic only", where the original birth country now has a one-to-many relationship with the current country, how should the reported original birthplace be coded? (Example: Yugoslavia)
Assign code for Europe, NOS (ZZE) for Yugoslavia, NOS, without further information.
Reportability/AmbiguousTerminology: Because there is a caveat in the SEER PCM, 3rd edition to ignore adverbs such as "strongly" when assessing reportability, should a term such as "likely" cancerous be reportable given than the expression "most likely" cancerous is reportable?
"Likely cancerous" is NOT reportable.
The CoC, NPCR and SEER have agreed to a strict interpretation of the ambiguous terms list. Terms that do not appear on the list are not diagnostic of cancer.
Histology/Behavior--Brain and CNS: How should Histology and Behavior be coded for a polymorphous low-grade neuroepithelial tumor of the young (PLNTY) arising in the brain?
Radiation Therapy: Is I 131 sodium iodide coded as radiation? SINQ 20031040 says to code Radiation as 3 (radioisotope) but SEER*Rx says not to code it.
Code sodium iodine (I 131) therapy in Radiation Treatment Modality as code 13 (Radioisotopes, NOS). Code Radiation External Beam Planning Technique as code 88 (not applicable). Do not code if used in diagnostic procedures.
Radioactive I 131 should be coded when given in therapeutic doses (usually 30-50mCi but could be higher in high risk patients). The same agent is used for diagnostic imaging, but the dose is very small (1-3mCi).
Reportability--Brain and CNS: Are lipomas of the spinal column reportable as a benign tumor of the central nervous system (CNS)? This is seen occassionally at our pediatric facility.
Spinal cord tumors (including lipomas) are reportable when they arise in the spinal dura or nerve root. The tumor must be of the spinal cord itself or within the spinal cord dura. Spinal cord tumors are reportable when they arise in the intradural space. A reportable intradural tumor can be either intramedullary or extramedullary. Extramedullary intradural spinal tumors are reportable. A spinal tumor originating in the extradural space is not reportable. If it is outside the dura, it is not reportable because it would be outside the CNS. They are not reportable when they arise in the peripheral nerves.
First Course Treatment/Other Therapy--Glioblastoma: Is Dendritic Cell/Tumor Cell Electrofusion Cancer Vaccine, coded to Immunotherapy as stated in SEER*Rx? A patient, diagnosed with Glioblastoma (GBM) IDH-wildtype (CNS WHO grade 4), in addition to radiation and chemotherapy, was enrolled on Diakonos/DOC-DBM study, randomized to the vaccine arm. It seems this study evaluates dubodencel, a novel dendritic cell vaccine treating GBM.
Code dubodencel to Other Therapy, code 2 (other-experimental). Dubodencel is not technically Dendritic Cell/Tumor Cell Electrofusion Cancer Vaccine, though close. However, both are in early stages of clinical development. We updated the coding instructions for Dendritic Cell/Tumor Cell Electrofusion Cancer Vaccine in SEER*Rx.
