Reportability/Date of Diagnosis--Ovary: Is a patient SEER reportable in 2001 or 2003 if she presented with a diagnosis of papillary serous tumor of low malignant potential [borderline tumor] per the 5/2001 surgery but at the time of the planned second look laparoscopic surgery is stated to have Stage 3A ovarian cancer? See Discussion.
A patient was seen in 5/2001 for large pelvic mass growing from right ovary. After TAH and USO and partial omemtectomy, path diagnosis was papillary serous tumor of low malignant potential (borderline tumor), unruptured. Right ovary and omental implant have identical histologic appearance, except the psammoma body formation and the ovary does not.
Patient does not return for lap as planned in 6-12 months.
In 1/03 she returns to hospital with abdominal pain and has debulking, hemicolectomy and Hartmann's procedure. 1/03 Path report "metastatic papillary serous adenoca." Chart now says "History of stage 3A ovarian cancer."
Yes, this case is reportable in 2003. Malignancy was confirmed in 2003. The diagnosis made in 2001 is not reportable for that year, and was not reviewed or revised according to the information provided.
Primary Site--Lymphoma: How should this field be coded when a diffuse large B-cell lymphoma is found in the femur and in the soft tissue of the anterior chest wall but all CT scans are negative for lymphadenopathy?
For cases diagnosed prior to 1/1/2010:Code the Primary Site field to C809 [Unknown primary site]. The primary site of diffuse large B cell lymphoma can be either nodal or extranodal. The case described above is likely extranodal because there is no evidence of lymph node involvement. Because the extranodal site of origin is unknown, code the Primary Site to C809.
For cases diagnosed 2010 forward, refer to the Hematopoietic and Lymphoid Neoplasm Case Reportability and Coding Manual and the Hematopoietic Database (Hematopoietic DB) provided by SEER on its website to research your question. If those resources do not adequately address your issue, submit a new question to SINQ.
Multiple Primaries (Pre-2007)--Kidney/Bladder/Renal Pelvis: Would transitional cell carcinoma of the left renal pelvis, diagnosed two years after a diagnosis of invasive bladder cancer, be a second primary when the discharge is "recurrent transitional cell carcinoma, left kidney"?
For tumors diagnosed prior to 2007:
This is an example of the term "recurrent" being used loosely to refer to another primary in the urinary tract. It is highly unlikely that a bladder tumor would metastasize to the kidney. Much more likely is the field defect or regional breakdown of the urothelial tissue that lines the tract from the renal pelvis to the urethra. Furthermore, bladder tumors don't spread retrograde to the kidney. Code as two primaries.
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--Prostate: We are seeing numerous pathology reports with the following diagnosis: "Conventional (acinar) prostatic adenocarcinoma (M81403)." What is the correct histology code?
For cases diagnosed prior to January 1, 2007, assign histology code 8550/3 [Acinar adenocarcinoma].
EOD-Extension--Retroperitoneum: Does the presence of "necrotic masses, NOS" in the blood, which are not pathologically evaluated, affect the coding of this field? See Description.
Encapsulated malignant tumor within the retroperitoneum was removed. Surgical report: "In the abdomen, blood had necrotic masses floating freely and encapsulated a 3-4" mass." No pathologic assessment of the necrotic masses is available.
For cases diagnosed 1998-2003: Necrotic masses do not affect the EOD-extension code.
EOD-Extension--Breast: If the pathology report states "infiltrating duct carcinoma...measuring 7mm in diameter...focal areas of intraductal carcinoma," do we code this field to 14 [Invasive and in situ components present, size of entire tumor coded in Tumor Size and in situ described as minimal] or to 16 [Invasive and in situ components present, size of entire tumor coded in Tumor Size and proportions of in situ and invasive not known]?
For cases diagnosed 1998-2003: If 7mm is the measurement of the infiltrating duct portion of this cancer, assign extension code 13 [Invasive and in situ components present, size of invasive component stated and coded in Tumor Size].
If 7mm is the size of the whole malignancy and the size of the invasive portion cannot be determined, assign extension code 14 [Invasive and in situ components present, size of entire tumor coded in Tumor Size (size of invasive component not stated) and in situ described as minimal (less than 25%)]. "Focal areas of in situ carcinoma" qualifies as minimal.
EOD-Lymph Nodes--Breast: When isolated tumor cells are found in an axillary lymph node, should lymph node involvement be coded to 0 [no lymph node involvement] or 1 [micrometastasis (less than or equal to 0.2 cm)]?
For cases diagnosed prior to 2004: Code the EOD-Lymph Node field to 0 [No lymph node involvement] when regional lymph nodes are negative, even if there are positive isolated tumor cells (ITC).
Histology (Pre-2007)--Lung: Does 8070 [squamous cell carcinoma], 8560 [adenosquamous carcinoma] or 8255 [adenocarcinoma with mixed subtypes] best represent this field for a lung biopsy described as a "poorly differentiated non-small cell carcinoma with squamous and glandular features with focal mucin positivity per mucin stain"?
For tumors diagnosed prior to 2007:
Assign code 8560/33 [Adenosquamous carcinoma, poorly differentiated]. "Glandular" carcinoma is a synonym for adenocarcinoma. Mixed adenocarcinoma and squamous carcinoma is coded to 8560. Do not use code 8255 [Adenocarcinoma with mixed subtypes] when a more specific complex code is available.
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-Extension--Lung: Is this field coded to 10 [tumor confined to one lung] or 20 [Tumor involving main stem bronchus >= 2 cm from carina] when there is no mention of the mainstem bronchus and a lobectomy is performed? See Discussion.
The clinical work-up shows a mass at the left medial apex extending into the left lung. No mention of the main stem bronchus. Because a lobectomy was performed, we assume, per Note 2, that the tumor was greater than or equal to 2 cm from the carina.
For cases diagnosed 1998-2003: Code the EOD-Extension field to 10 [tumor confined to one lung] for the case example. The EOD-Extension code 20 [Tumor involving main stem bronchus >= 2 cm from carina] applies to tumors involving the main stem bronchus.
