EOD-Extension/EOD-Lymph Nodes--Bladder: Are "perivesical nodules" coded in the EOD-Lymph Nodes field or are they discontinuous extension and coded in the EOD-Extension field?
For cases diagnosed 1998-2003:
Code "perivesical nodules" in the EOD-Lymph Nodes field as involvement of regional lymph nodes. Each gross nodule of metastatic carcinoma in the fat surrounding an organ is counted as one positive regional lymph node.
EOD-Size of Primary Tumor--Breast: When the pathology report does not specify dimensions for the invasive component, how is tumor size coded? See discussion.
In some cases the tumor has both invasive and in situ components. The pathologist sometimes does not report the size for the invasive portion of the tumor. In most cases, the invasive portion is described as a percentage of the tumor mass.
From January 1, 1998 and forward: Follow the Revised Breast EOD instructions. If the size of the invasive component is not given, record the size of the entire tumor in the EOD-Size of Primary Tumor field. Assign the appropriate EOD-Extension code for the situation.
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.
Surgery of Primary Site/Date Therapy Initiated--Cervix: Should "negative endocervical curettings" be coded as surgical treatment for carcinoma in situ of the cervix primaries and should the date of the procedure ever be used in coding the Date Therapy Initiated field?
For cases diagnosed 1/1/2003 and later: Code Surgery of Primary Site to 25 [D&C; endocervical curettage (for in situ only)]. If this is the first treatment given, the Date Therapy Initiated is coded to the date of the curettage.
Histology (Pre-2007)/Grade, Differentiation: What code is used to represent the histology "cystadenocarcinoma with multiple foci of high grade anaplastic and undifferentiated sarcoma"? See discussion.
The case was presented at tumor conference. The physicians indicated that the patient would not have the same disease course as a patient with cystadenocarcinoma of the ovary. The physicians advised the use of a mixed histology code. However, there is no appropriate mixed histology code for cystadenocarcinoma, anaplastic carcinoma, and sarcoma. It doesn't seem as though these cases should be grouped and analyzed with cases having a single histology of cystadenocarcinoma.
For tumors diagnosed prior to 2007:
Code the Histology and Grade, Differentiation fields to 8440/34 [cystadenocarcinoma, anaplastic] because a combination code for the specified histologic type does not exist.
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.
Surgery of Primary Site--Ovary: What code is used to represent this field when a patient has a history of a previous organ removal and has additional surgery/organ removal for a present cancer (e.g., History of a 1984 hysterectomy and in 2003 has ovarian primary treated with BSO)?
For cases diagnosed 1/1/2003 and after: Code the Surgery of Primary Site field to 52 [Bilateral salpingo-oophorectomy WITH hysterectomy].
First Course Treatment: If the patient receives no treatment at the time of diagnosis (either because it is not recommended or because the patient refused treatment at that time) but treatment is later instituted after disease progression, should this treatment be coded as part of the first course of treatment?
The SEER rules changed in 1998 regarding what constitutes First Course of Cancer-Directed Therapy.
For cases diagnosed on or after 1/1/98: The First Course of Cancer-Directed Therapy fields will all be coded to 0 [None] for these types of cases. The documented disease progression would stop the timeframe for inclusion of any treatment to be part of first course of therapy.
Histology (Pre-2007): What code is used to represent the histology "papillary adenocarcinoma: mixed serous, endometrioid and mucinous subtypes"? See discussion.
Example: Fallopian tube right (salpingectomy): Primary adenocarcinoma: mixed serous, endometrioid, and mucinous subtypes
For tumors diagnosed prior to 2007:
For cases diagnosed on or after 1/1/98: Code the Histology field to 8323/3 [adenocarcinoma, mixed cell]. The case is coded using the mixed histology rule A in the Coding Complex Morph Dx's.
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.
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:
