Surgery of Primary Site/Reconstruction-First Course--Breast: If the plan is to "reconstruct" the breast 6 months after an ipsilateral modified radical mastectomy, is the time span a problem or should it be coded in the Surgery of Primary Site field because it was planned?
For cases diagnosed 1/1/2003 and after: Code the Surgery of Primary Site field to 55 [Modified radical mastectomy WITHOUT removal of uninvolved contralateral breast, Implant]. The time span is not a problem as long as the reconstruction was planned as first course, which is indicated by tissue expander insertion at the time of the original surgery.
Grade, Differentiation--Brain and CNS: Can grade IV be implied for brain primaries with the histology of glioblastoma multiforme, even if there is no statement of grade in the path report? See discussion.
Dr. Platz has instructed the Iowa registry to code glioblastoma multiforme to grade IV, even when there is no corroborating statement of grade in the path report. This is also supported in some references.
Code the Grade, Differentiation field to 9 [Cell type not determined, not stated or not applicable] in the absence of a stated grade on the pathology report. If a grade is stated, code the stated grade. SEER does not recommend adopting the rule in the Discussion.
EOD-Clinical Extension/EOD-Lymph Nodes--Prostate: How do you code clinical extension and lymph nodes for path only prostate cases treated with a TURP? Would clinical extension be coded to unknown or localized, NOS?
For cases diagnosed 1998-2003: Code the EOD-Clinical Extension field to 30 [localized, NOS] and the EOD-Lymph Nodes field to 0 [no lymph node involvement]. Per Note 7: Use code 30 when there is insufficient information as to whether the tumor is clinically apparent or inapparent but the tumor is confined to the prostate. This is an example of a case where there is insufficient information as to whether the tumor is clinically apparent or inapparent. Assume the tumor is confined to the prostate.
EOD-Pathologic Review of Number of Regional Lymph Nodes Positive and Examined--Colon: What codes are used to represent these fields when the pathology from a colon cancer resection describes 2/16 positive pericolonic lymph nodes and a "metastatic nodule in the pericolonic fat"?
For cases diagnosed 1998-2003:
Code the Number of Regional Lymph Nodes Positive field to 03 and the Number of Regional Lymph Nodes Examined field to 17. Each grossly detectable nodule in the pericolonic fat is counted as one regional lymph node.
Behavior Code--Bladder/Lymphoma: Should the "in situ" designation on a bladder primary's pathology report be ignored that states a diagnosis of "in situ lymphoma"?
Ignore the in situ designation. You cannot assign an in situ behavior code to a lymphoma primary. The term or designation of "in situ" is limited to solid tumors; carcinoma and/or cancer.
CS Extension--Prostate: How do you code clinical extension for prostate primaries diagnosed at autopsy? See discussion.
A patient was not diagnosed prior to autopsy. The autopsy diagnosis states that this is adenocarcinoma of the prostate without capsular invasion.
Should clinical extension be coded to clinically inapparent, NOS (10) and pathologic extension be coded to no prostatectomy done within first course of treatment (97)?
Code CS Extension (clinical) to 99 [Unknown]. Code SSF 3 according to the amount of tumor found using the information from the autopsy.
Radiation: Is "consolidated" radiation therapy coded as part of first course therapy when there is no documentation of "planned treatment" and the radiation is done 4 months after the initiation of treatment?
Yes, "consolidation" treatment is part of a planned treatment regimen. A treatment regimen may consist of the four following phases:
EOD-Extension/EOD-Lymph Nodes--Lung: Is "subcarinal extension" with no mention of lymph nodes coded in the EOD extension field or in the EOD lymph node involvement field? See discussion.
Should "subcarinal extension" with no mention of lymph nodes be assumed to be direct contiguous extension of the primary tumor or does it represent lymph node involvement?
If it is direct extension, should we code it as 70 in the extension field? If not, should we code it as 2 in the lymph node involvement field?
For cases diagnosed 1998-2003:
Code the EOD-Extension field to 70 [mediastinum, direct extension].
Terminology: Do focus, focal, foci and chips mean the same thing?
Focus, focal, and foci are variations of the same word. Focus (noun) describes an area or point of disease, either grossly or microscopically. Focal (adjective) relates to the area/focus of disease; an example is a prostate with focal adenocarcinoma. This means that the majority of the prostate is benign and the adenocarcinoma is confined to one small area/point. Foci (plural) describe more than one area/focus of disease. A prostate with foci of adenocarcinoma means the disease is multifocal (several areas/points of disease).
Chips are microscopic amounts of either tissue or tumor. A pathologist might examine several chips of prostate tissue, one of which contains a focus of adenocarcinoma.
Multiple Primaries (Pre-2007)--Thyroid: Does the rule in the 3rd Edition of the SEER Program Code Manual apply to cases diagnosed before 1998 that states if there are two separate carcinomas in the thyroid, one papillary and the other follicular, it is one primary and coded to the combination code 8340/3 [Papillary and follicular carcinoma]? See discussion.
If the rule applies to cases diagnosed before 1998, does SEER plan to ask that cases diagnosed prior to 1998 be recoded?
The rule applies to tumors diagnosed 1998-2006. The rule is not retroactive. At this time, SEER does not plan to ask that tumors diagnosed prior to 1998 be recoded.
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.
