CS Lymph Nodes--Breast: How is this field to be coded if the pathologist staged the case pN1a and the lymph node is stated to be negative on H&E, is .3 cm on IHC stain for pancytokeratin but on review of smears shows no malignant cells?
This answer was provided in the context of CSv1 coding guidelines. The response may not be used after your registry database has been converted to CSv2.
Code CS Lymph Nodes as negative [00]. The positive stain for pancytokeratin is contradicted by the statement "malignant cells are not identified." See also sinq 20010055.
Histology (Pre-2007)--Ovary: What codes are used to represent "mixed papillary serous and clear cell carcinoma" and "papillary serous carcinoma with focal clear cell features" of the ovary?
For tumors diagnosed prior to 2007:
Assign code 8323 [Mixed cell adenocarcinoma] to "mixed papillary serous and clear cell carcinoma." This is histology coding rule 3 in the 2004 SEER manual under single tumor (page 86). There is no other code for this mixture.
Example 1: 8323
Example 2: 8461 (clear cell is not coded according to Rule 6, page 87, because it is not the majority of the tumor).
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.
Chemotherapy/Immunotherapy: How do we code Rituxan for Non-Hodgkin Lymphoma and Herceptin for breast cancer? See Discussion.
Page 195 of the SEER Manual 2004 lists these as examples of Immunotherapy. The new SEER*Rx categorizes these as chemotherapy.
(Sinq # 20041025 says to code Avastin and Erbitux as chemotherapy, too.)
Code Rituxan and Herceptin as chemotherapy.
SEER*Rx is effective for cases diagnosed 1-1-2005 and forward. It replaces all previous references. Be sure to use SEER*Rx [http://seer.cancer.gov/tools/seerrx/]
because some agents changed categories when SEER*Rx was deployed.
It is neither required nor recommended that cases treated prior to 2005 be recoded.
Priorities/CS Tumor Size--Breast: What is the priority order used in coding tumor size for this site when there is a larger 2 cm lesion noted on the PET scan and smaller sizes described in the pathology report as two malignant masses one measuring 0.8 cm and the second measuring 1.0 cm per the GROSS?
This answer was provided in the context of CSv1 coding guidelines. The response may not be used after your registry database has been converted to CSv2.Code CS Tumor Size as 1.0 cm. The pathology report is the highest priority source for coding tumor size. When multiple tumors are present, code the size of the largest tumor.
Primary Site--Soft Tissue: How is the primary site coded for a PNET found in the groin when the Tumor Board states the primary is unknown but the SEER site/histology validation table does not allow a site of C809 or C76x to be coded in combination with the histology of 9473/3?
Code site to C495 [connective tissue of pelvis, groin].
This was not called metastatic PNET and no other site of disease is noted. PNET is a broad classification of a group of tumors that usually occur in the CNS and can also occur in soft tissue (neuroblastoma, extra-osseous Ewing sarcoma).
Multiple Primaries (Pre-2007)/Recurrence--Cervix: How many primaries should be abstracted if a patient had a diagnosis in 1998 of adenocarcinoma in situ of the cervix treated with a total hysterectomy and a July 2004 vaginal mass biopsy with a diagnosis of invasive adenocarcinoma that is consistent with an endocervical primary?
For tumors diagnosed prior to 2007:
Abstract the July 2004 diagnosis as a new endocervical primary. Abstract an invasive cancer in the same site more than two months after an in situ cancer as a new primary. Residual cervical tissue is present following a hysterectomy.
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.
CS Extension/CS Site Specific Factor--Breast: How is extension (localized or unknown) and SSF6 (entire tumor in situ or 888) coded for an in situ breast primary in which bone metastasis is diagnosed 4 months following the mastectomy? See Discussion.
In situ breast primary with bone mets. No mets work up prior to mastectomy done 2/04. Path: 2.5 cm mass: ductal carcinoma in situ, solid type, with comedonecrosis (no invasive carcinoma found in mastectomy specimen). Bone scan done 4/04 showed compression fractures. MRI 6/04 showed diffuse metastatic disease of the bones.
This answer was provided in the context of CSv1 coding guidelines. The response may not be used after your registry database has been converted to CSv2.
First, determine whether the bone mets in this case are progression of disease. If the patient was asymptomatic at the time of the mastectomy, the bone mets are disease progression, not initial stage.
If the initial stage includes the bone mets and they are not disease progression, extension must be coded to at least 10. Code site-Specific Factor 6 to 040 [Size of entire tumor coded, size of invasive component not stated].
Histology--Lymphoma: How is "histiomonocytic lymphoma" coded?
For cases diagnosed prior to 1/1/2010:Assign code 9755 [Histiocytic sarcoma; True histiocytic lymphoma]. "Histiomonocytic" is not standard terminology, according to our expert consultant. However, 9755 is the best code to assign.
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.
Surgery of Primary Site--Prostate: How is the use of a Laserscope Niagara laser (modulated KTP-YAG laser beam (Niagara 122 prostate vaporization)) coded for prostate primaries? See Discussion.
The Laserscope Niagara laser performs an operation similar to the TURP, but there is virtually no bleeding and patients can sometimes go home the same day, most without a catheter. The laser is delivered through a fiber (the thickness of hair) into the cavity via an endoscope inserted through the urethra.
When performed as part of the first course of therapy, assign surgery code 15 [Laser ablation] to Niagara laser photovaporization of the prostate.
Behavior/Date of Diagnosis--Lung: If the term "Pancoast tumor, NOS" is malignant by definition, should the date of diagnosis be coded to the date of the clinical diagnosis when the clinical diagnosis is made prior to the histologic confirmation of the malignancy?
Yes, Pancoast tumor is by definition malignant. It is defined as a lung cancer in the uppermost segment of the lung that directly invades into the brachial plexus (nerve bundles) of the neck, causing pain. If a Pancoast tumor was identified on imaging prior to the biopsy, the date of diagnosis should be linked to the Pancoast tumor report.
