CS Site Specific Factor--Breast: If the tumor is described as being a 1 cm poorly differentiated pleomorphic lobular carcinoma with scattered LCIS in breast tissue, for SSF6, do we use the breast tumor or all of the breast tissue removed when coding SSF6?
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.
Site Specific Factor 6 in the breast scheme describes the relationship of invasive and in situ tumor in the tumor size coded. Code SSF6 for the same tumor used to code tumor size.
For this example, code SSF6 for the 1 cm tumor. In this case, the entire tumor is reported as invasive; use code 000 [Entire tumor reported as invasive].
CS Site Specific Factor--Prostate: Can autopsy results also be used when coding SSF3, pathologic extension, given that the instructions only address the use of prostatectomy findings when coding this field?
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.
If the prostate cancer was diagnosed on autopsy, or the autopsy was performed within the staging timeframe (See 2004 SEER Manual, page 112), code SSF3 using the autopsy information.
CS Lymph Nodes--Breast: Is it better to code to 26 [Stated as N1, NOS] or 28 [Stated as N2, NOS] instead of 60 [Axillary/regional lymph nodes, NOS; Lymph nodes, NOS] when the only information in the medical record is the TNM N1 or N2 physician stage?
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.
Yes. When the only indication of lymph node involvement is the physician's N category from TNM, code the numerically lowest equivalent CS Lymph Nodes code for that N category.
In the breast schema, CS Lymph Nodes code 26 corresponds to N1, NOS and code 28 corresponds to N2, NOS.
CS Lymph Nodes--Lung: If the lymph nodes listed in codes 10 and 20 were contralateral or bilateral, and the only description was "mass", "adenopathy", or "enlargement" on mediastinoscopy or x-ray, is this field coded to 60? See Discussion.
(CS Manual page 407) Note 2: If at mediastinoscopy/x-ray, the description is "mass", "adenopathy", or "enlargement" of any lymph nodes named as regional in codes 10 and 20, assume that at least regional lymph nodes were involved.
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.
Yes. The named nodes listed in codes 10 or 20 should be coded 60 if the "mass", "adenopathy", or "enlargement" on mediastinscopy or x-ray is described as bilateral or contralateral.
CS Extension--Prostate: For a tumor that is clinically inapparent, but a biopsy from the prostatic apex is positive, is this field coded to 15 [Tumor identified by needle biopsy, e.g., for elevated PSA (clinically inapparent)]?
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.
Yes. Code CS Extension-Clinical Extension to 15 [Tumor identified by needle biopsy, e.g., for elevated PSA (clinically inapparent)] for clinically inapparent prostate cancer with positive apex biopsy.
CS Site Specific Factor 6--Breast: Can we interpret the in situ component as "minimal" when the pathology report states "1.1 cm infiltrating duct carcinoma and no extensive intraductal component"?
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.
Yes. Based on the information provided above, the in situ component is "mininmal" for the purpose of coding Breast CS Site Specific Factor 6. The phrase "no extensive intraductal component" suggests that there is some intraductal carcinoma present.
CS Site Specific Factor/Terminology--Breast: Does the term "focal areas" of in situ carcinoma qualify as "minimal" in situ component when coding SSF6 field (assessment of the invasive and in situ components present) in the CS breast scheme?
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.
Yes, the term "focal areas" of in situ carcinoma describes a minimal in situ component.
CS Lymph Nodes/Scope of Regional Lymph Node Surgery--Prostate: When prostate cancer is an incidental finding at cystoprostatectomy for bladder cancer, is the pelvic lymph node dissection coded for the prostate as well as the bladder?
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.
Yes, the pelvic lymph node dissection is coded as regional lymph node surgery for both primaries and the nodes are counted in collaborative staging for both primaries. The examination of the pelvic lymph nodes is relevant to both the bladder and the prostatic primaries.
CS Extension--Lung: Can extension be coded to 10 (Tumor confined to one lung) when either an autopsy or a CT scan describes the tumor as a mass of a specified size located in one lobe of the lung without any description of extension and no available TNM provided? See Discussion.
Example 1: Lung primary within the right lower lobe described clinically as greater than 3 cm on scan but was found to be 3 cm at autopsy.
Example 2: CT scan February shows 2 cm mass in RUL.
In both cases, the only tumor description was the size of tumor without any information regarding extension.
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.
Yes, assign code 10 [Tumor confined to one lung] for a mass in one lobe when none of the descriptions in codes 11 to 80 are documented.
Collaborative Staging--Lung: Given that the AJCC lung TNM is not applicable for a high grade sarcoma of this site, how do we code Collaborative Stage for this site/histo combination when the pathologist indicates a TNM stage of T2bN0M0=stage III, using AJCC Soft Tissue Sarcoma schema?
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.
Use the lung schema to code CS for sarcoma of the lung. Complete the CS information as best you can from the medical record WITHOUT using the TNM Soft Tissue Sarcoma staging form. Visceral sarcomas are specifically excluded from soft tissue sarcoma TNM staging and sarcomas are excluded from the TNM staging for lung.
Sarcoma is listed on the Histology Exclusion Table for lung. When a case is coded in Collaborative Staging and the histology is on the exclusion list, SEER Summary Stage 1977 and 2000 can be assigned. For these cases, TNM will not be calculated and displayed results will be "T NA N NA M NA and Stage Group NA".
