Reportability--Myelodysplastic Syndrome: How we handle cases of myelodysplastic syndromes identified in 2001 casefinding documents that are determined to have an "unknown diagnosis" date after review of the patient's hospital medical record?
Myelodysplastic syndrome cases with unknown dates of diagnosis identified in pre-2001 casefinding documents should not be accessioned and are not SEER reportable.
For cases identified in 2001 casefinding documents, when the diagnosis date cannot be confirmed using the medical records typically accessed by the registrar or central registry staff, do not accession these cases; they are not SEER reportable. This default applies only to those cases identified in 2001 casefinding documents.
For cases identified in 2002 or later casefinding documents, the attending physician should be contacted and asked to clarify the diagnosis date for cases identified with unknown dates of diagnosis. Clarifying the diagnosis date is necessary to determine whether the case is reportable and whether it should be accessioned.
Histology (Pre-2007): Can adenocarcinoma in either a villous or tubulovillous polyp or adenoma be coded as histology for sites other than colon or rectum? See discussion.
When adenocarcinoma of the endometrium arises in a villoglandular polyp is the histology coded as 8263/3?
For tumors diagnosed prior to 2007:
Code the Histology field to 8263/3 [adenocarcinoma in a tubulovillous adenoma]. Histology codes 8261 [adenocarcinoma in a villous adenoma] and 8263 [adenocarcinoma in a tubulovillous adenoma] are used for non-colorectal sites when the cancer arises in a polyp.
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.
Histology (Pre-2007)--Breast: Are diagnoses of "infiltrating duct and mucinous carcinoma" and "duct carcinoma, mucinous type" both coded to the histology code of 8523/3?
For tumors diagnosed prior to 2007:
Code "Infiltrating duct and mucinous carcinoma" to 8523/3 [Infiltrating duct mixed with other types of carcinoma] according to the instructions for coding a single tumor with complex histology in Appendix C of the 2004 SEER manual. Assign code 8523/3 when the diagnosis is duct carcinoma mixed with another type of carcinoma. Look for "and" or "mixed" in the diagnosis.
Code the Histology field for a "ductal carcinoma, mucinous type" to 8480/3 [Mucinous carcinoma].
The instructions for coding a single tumor with complex histology are to code the specific type if the diagnosis is "Duct carcinoma, _____ type."
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.
EOD-Size of Primary Tumor: Should the code 001 in tumor size be used for tumors described as having "focal" involvement? See discussion.
Is tumor size coded to 001 for the following examples:
Example 1: Focal adenoca in left lobe on prostatectomy.
Example 2: Multifocal ductal carcinoma of breast on mastectomy.
Example 1 and 2: There is insufficient information in the examples to determine whether EOD-Size of Primary Tumor should be coded to 001.
The instructions are that code 001 is used for a microscopic focus or foci of tumor only. That means that the tumor is small enough that it could not be seen by the naked eye, nor would it be palpable. Be careful with the term "focal" because it is most often used to describe tumor cells grouped or concentrated in one area as in example 1. There is no implication that this focus was microscopic only. Was it mentioned in the gross or macroscopic portion of the pathology report? If so, it is not coded to 001. Was it palpable? If so, it is not coded to 001.
Example 2 cites a multifocal breast cancer. Again, did the pathologist visualize the cancer (was it reported on the gross or macroscopic portion of the pathology?) If so, do not use code 001. Was the lesion palpable? If so, do not use code 001.
Scope of Regional Lymph Node Surgery: Should this field be coded to "unknown or not applicable" for all hematopoietic morphologies, brain primaries and unknown primaries?
For cases diagnosed 1/1/2003 and after: Code the Scope of Regional Lymph Node Surgery field to 9 [Unknown or not applicable] for all hematopoietic morphologies, brain primaries and unknown primaries. .
Date of Diagnosis--Lung: Based on Note 7 in the lung EOD, should the Date of Diagnosis field be coded to an earlier CT scan date with a reported diagnosis of "RUL mass with mediastinal lymphadenopathy" or to the later biopsy date with a reported diagnosis of small cell carcinoma? See discussion.
Note 7 states that "mediastinal lymphadenopathy" indicates involved lymph nodes for lung primaries. Should the date of diagnosis be back-dated to the date of the scan?
For cases diagnosed 1998-2003:
No, code the Date of Diagnosis field to the later biopsy date. Note 7 is intended for use in coding the EOD-Extension field, not the Date of Diagnosis field. The earlier scan has a diagnosis of RUL "mass" not a "malignancy" so the fact that there is mediastinal lymphadenopathy mentioned in that scan is not used to help determine date of diagnosis.
1) If Van Nuys nuclear grade 2 is the only grade given for an in situ breast primary, would it be coded as a 3-component system (e.g., 2/3 = 3)?
2) Is there a way of determining grade if only the total Van Nuys Prognostic index score is given (e.g., score 7/9)?
1. Code Van Nuys grade 2 as code 2 [Grade 2] in the Grade, Differentiation field.
2. Code Van Nuys score of 7 as 9 [Cell type not determined, not stated or not applicable] in the Grade, Differentiation field.
Currently, there is no conversion from the total Van Nuys score to grade because "grade" represents only one of the three Van Nuys factors that make up the total score. The other factors are tumor size and margin. The grade represents from 1 to 3 points within the total Van Nuys score. The total score can be between 3 and 9.
First Course Treatment: What code is used to represent each treatment modality field when there is no indication that a particular modality of treatment was recommended or started?
Code the individual treatment fields to 0 or 00 [None] when the modality is not addressed in the treatment plan (or when a treatment plan is lacking) and there is no indication that a particular modality of treatment was recommended or started.
Primary Site/EOD-Extension/EOD-Lymph Nodes--All Sites: What codes are used to represent these fields for an "extramedullary myeloid tumor (granulocytic sarcoma)" of the colon with positive or negative lymph nodes?
For cases diagnosed 1998-2003:
If only the extramedullary site is involved, such as colon, code the Primary Site field to the site of origin. Granulocytic or myeloid sarcoma is an exception to the rule that all leukemias should be coded to bone marrow as the primary site. Granulocytic sarcoma is a deposit of malignant myeloid cells in a site other than bone marrow (extramedullary). For EOD staging, granulocytic sarcoma [9930/3] is included in the Hematopoietic, Reticuloendothelial, Immunoproliferative and Myeloproliferative Neoplasms scheme and the Extension field is coded to 10 when the lymph nodes are negative, since it (like solitary plasmacytoma) is a localized deposit of tumor.
However, if the regional lymph nodes associated with the extramedullary primary site are involved, code the EOD-Extension field to 80 [Systemic disease] because the disease is no longer an isolated deposit of malignant granulocytes (in other words, it is not localized).
The EOD-Lymph Nodes field is coded to 9 regardless of whether or not the lymph nodes are involved because that is the only allowable code for that field.
