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--Lung: Is bilateral pleural effusion coded as 72 [malignant pleural effusion] or 85 [metastasis]? See discussion.
Example:
10/30/98 CXR: Widespread malignancy, hilar, superior mediastinal masses, bilateral pleural effusions, fullness in soft tissue right neck.
11/01/98 CT chest/ABD: Extensive infiltrate mediastinum by radiolucent tumor mass that engulfs esophagus/trachea. Pleural effusion extends so low it apes ascites. Normal ABS/pelvis.
11/01/98 Pathology: FNA right supraclavicular lymph node: metastic oat cell ca. Sputum cytology reported to be negative.
For cases diagnosed 1998-2003, code the EOD-Extension field to 72 [malignant pleural effusion; pleural effusion, NOS].
Multiple Primaries (Pre-2007)--Ovary/Endometrium: Is endometrioid adenocarcinoma occuring simultaneously in the left ovary and the endometrium one primary or two? See discussion.
Pathology Final Diagnosis:
Left Ovary: Moderately differentiated endometrioid adenocarcinoma squamous differentiation grade 2 (scale of 3)
Uterus: Moderately differentiated endometrioid adenocarcinoma with squamous differentiation, grade II (scale of III). Focal, very superficial invasion to inner third myometrium with extension to lower uterine segment. Endocervix, cervix, right ovary and fallopian tubes negative for tumor.
For tumors diagnosed prior to 2007:
Code the case you describe as two primaries. The endometrioid adenocarcinoma can arise in the endometrium without a concomitant ovarian carcinoma.
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.
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.
Primary Site--Esophagus: What is the difference between C15.5 [Lower third of esophagus] and C15.2 [Abdominal esophagus]?
These descriptions represent the use of two different ways the esophagus can be divided anatomically. The two different systems used are illustrated in the SEER Self Instruction Manual for Tumor Registrars: Book 4. Assign the primary site code that describes the location of the tumor in the same way the tumor's location is described in the medical record.
EOD-Pathologic Extension--Prostate: Can a pathological extension code be assigned when a retropubic prostatectomy is done? See discussion.
The TNM manual states, "Total prostatoseminalvesiculectomy and pelvic lymph node dissection are required for pathologic staging."
For cases diagnosed 1998-2003:
The pathology report from a retropubic prostatectomy should be used to code the Pathologic Extension field. This field is coded using pathology report information from the prostatectomy operation regardless of the surgical approach and regardless of whether or not a pelvic lymph node dissection was performed. This is one area in which TNM rules for pathologic staging and SEER rules for EOD are slightly different.
Primary Site--Lymphoma: How should you code the primary site for a lymphoma that presents with involvement of an extranodal site and regional lymph nodes? See discussion.
1. Lymphoma involves the spleen and the splenic lymph nodes.
2. MALT Lymphoma involves the stomach and the gastric and iliac lymph nodes.
1. Code the Primary Site field to C42.2 [spleen].
2. Code the Primary Site field to C16._ [stomach].
When lymphoma presents in an extranodal site and in the regional lymph nodes for that extranodal site, code the Primary Site field to the extranodal site. The typical disease process is that lymphoma can spread from an extranodal organ to its regional lymph nodes. It cannot metastasize from the regional lymph node to the extranodal organ. The exception to this would be if the lymph nodes presented as one large mass that extended into the regional organ.
Primary Site--Breast: What subsite code should be used for a diagnosis of "inflammatory carcinoma"?
Code the Primary Site field to C50.9 [Breast, NOS] for a breast primary presenting with inflammatory cancer unless there is a palpable mass within the breast. If there is a palpable mass, code the primary site to the position of the mass.
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.
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.
