20051086 | CS Site Specific Factor 4--Prostate: For apex involvement at prostatectomy, is only apical involvement found at prostatectomy included or is all histologically proven apical involvement documented in the second digit of Site Specific Factor 4? See Discussion. | Per note 1 for Site Specific Factor 3 - Pathologic Extension all histologic information is used. Biopsy information would be included when coding path extension. Would all histologic information be used for coding prostatectomy apex involvement in Site Specific Factor 4? Example 1: Prostate biopsies of the right and left apex and right and left mid gland show adenocarcinoma. Prostatectomy shows bilateral adenocarcinoma. Apex negative for tumor. Example 2: Prostate biopsies of right apex and mid gland show adenocarcinoma. There is no mention of apex on prostatectomy path. How is CS Site Specific Factor 4 Prostate Apex Involvement coded? |
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. Assign the second digit of CS SSF 4 based on prostatectomy only, do not include biopsy or other histologic information in the second digit. According to the CS Steering Committee, the clinical or biopsy of the prostate is included in the first number of the code and should not be combined with the prostatectomy code which is the second number. These were separated purposely. Example 1: Code the second digit of SSF 4 based on the prostatectomy, 1 [no involvement of prostatic apex]. Example 2: Code the second digit of SSF 4 based on the prostatectomy, 5 [apex extension unknown]. |

20051033 | CS Site Specific Factor--Melanoma: What is the correct code for measured thickness in SSF 1 for a melanoma of the choroid without an enucleation? See Discussion. | CS Site Specific Factor 1 for melanoma of the choroid codes "Measured Thickness (Depth), Breslow's Measurement." The note for this field states "Record actual measurement in millimeters from the pathology report." For melanoma of the eye, there is often only an eye exam report stating the thickness. Can PE thickness (clinical statement only) be coded for SSF 1 or is this field coded only from pathology? (i.e., all cases treated without enucleation would have this field coded to 999) | 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 SSF 1 999 [Unknown] when there is no enucleation, and therefore, no pathology report for a choroid melanoma. |

20051058 | Primary Site/Histology (Pre-2007)--Rectum: How are rectal biopsies with the histology of "poorly differentiated carcinoma with mixed basaloid and squamous features" coded if, per the SEER site/histology validation table, the histology 8094/3 [basosquamous carcinoma] histology cannot be coded to the rectum for the primary site? | For tumors diagnosed prior to 2007:
Code primary site C209 [rectum] and histology 8094/3 [basosquamous carcinoma]. As of 6/9/2003, this is no longer an impossible site/histology combination.
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. |

20051134 | 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. |

|
20051115 | Histology (Pre-2007)--All Sites: How are "malignant cells" in a cytology or "probably malignancy" in a CT scan coded? | For tumors diagnosed prior to 2007:
Assign code 8001/3 [Tumor cells, malignant] when the only information available is a cytology report stating "malignant cells." Assign code 8000/3 [Neoplasm, malignant] when then only information available is a CT report stating "probable malignancy." See ICD-O-3 page 27 for an explanation of "cancer" [8000] and "carcinoma" [8010].
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. |

20051090 | Histology--Leukemia: How is "T-Cell prolymphocytic leukemia, cerebriform (Sezary cell-like) variant" coded when the pathology report COMMENT states: The cerebriform (Sezary cell-like) variant accounts for about 5% of cases of T-cell prolymphocytic leukemia? | For cases diagnosed prior to 1/1/2010: 9834/3 [Prolymphocytic leukemia, T-cell type]. According to the WHO Classification of Haematopeietic and Lymphoid Tissue Tumours, cerebriform or Sezary cell-like is a variant form of T-cell prolymphocytic leukemia. 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. |

20051140 | CS Reg LN Pos/Exam--Breast: How are nodes positive/examined coded for a positive FNA of a lymph node followed by a subsequent lymph node dissection? See Discussion. | A breast cancer patient had an FNA of an axillary lymph node positive for metastases. A modified radical mastectomy with lymph node dissection showed six lymph nodes negative for metastases. Example 1: Patient received neoadjuvant chemotherapy prior to mastectomy and lymph node dissection. Example 2: Patient received no neoadjuvant therapy. This question is answered for EOD in SINQ 20031059. What is the answer for Collaborative 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.Include all nodes examined by the pathologist in Regional lymph nodes positive and Regional lymph nodes examined, unless there is disease progression. These fields are cumulative -- record the total number of regional nodes positive and examined during first course of treatment. Preoperative treatment does not affect the coding of these fields. An FNA alone, positive for regional lymph node metastasis is coded as 95 for number positive and 95 for number examined. For the case examples above, assuming there has been no disease progression, include all nodes positive and all nodes examined from both the FNA and the lymph node dissection in the counts. Code number of regional nodes positive as 01, number examined as 07 for both examples. |

20051112 | Collaborative Staging--Hematopoietic, NOS: Which Collaborative Staging schema is used for a connective, subcutaneous and soft tissue primary of the pelvis [C495] with the morphology of Langerhans cell sarcoma [9756/39]? See Discussion. | On page C-411 of the SEER manual for the connective, subcutaneous, and other soft tissues schema it lists exceptions for certain morphologies and the above is not listed as an exception. On the Hematopoietic scheme it lists the above morphology. | 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 hematopoietic schema on page C-709 of the 2004 SEER manual. The histologically defined schemas have priority over the site schemas when both apply. See page 115 of the 2004 SEER manual.
The morphology codes listed on page C-411 pertain to the SEER Site Specific Guidelines. |

20051131 | Recurrence/Multiple Primaries (Pre-2007)/Primary Site--Breast: Is a malignancy that occurs in 2005 in a mastectomy scar years following an original diagnosis of breast cancer in 1971 a recurrence (not reportable) or a new primary (breast or chest wall, NOS)? See Discussion. |
The patient had a right mastectomy for breast carcinoma in 1971. In 2005, she came in with a mass in the right axilla and a right chest wall mass in the mastectomy scar. Excision of the axillary mass and biopsy of the chest wall mass revealed invasive adenocarcinoma with a similar histologic pattern. The axilla specimen contained no benign breast tissue. IHC stains exhibit strongly positive for ER, mildly positive for PR and negative for HER2/neu. The pathologist says "Although these findings are consistent with recurrent breast carcinoma, they are not specific for such. Recurrence after 34 yrs. is most unusual." |
For tumors diagnosed prior to 2007: The 2005 diagnosis is a new primary. The 1971 site differs from the 2005 site and there are more than two months between the two. Without further information, assign topography code C761 [chest wall]. The pattern of spread, including regional extension, is different for a primary of the chest wall compared to a primary in the breast. Coding the primary site to C761 will group this case with similar cases. If further information can be obtained, look for old records that describe the extent of the 1971 mastectomy. It is possible that there was breast tissue left on the chest wall. Residual breast tissue is often present following mastectomy (simple, modified, or even radical). New carcinoma can develop in the remaining breast tissue. 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. |
