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. |

20051036 | Date of Diagnosis--Sarcoma: Should the date of diagnosis be coded to the date of biopsy or the date of birth for an infant biopsied at 3 days of age and stated to have a diagnosis of congenital alveolar rhabdomyosarcoma, widely metastatic? | Code the date of the biopsy as the date of diagnosis. This is the date the cancer was first identified by a medical practitioner. Note: SEER collects the Month and Year of diagnosis. The "day" of diagnosis is not collected by SEER. |

20051103 | CS Extension/Histology (Pre-2007)--Melanoma: When do the terms "regression is present," "apparent regression," or "undergoing regression" affect the coding of melanoma cases? See Discussion. | For melanoma, many path reports document the presence or absence of regression. At what point does the presence of regression become significant enough to code it for histology and for CS Extension?
Example 1: Skin biopsy showed malignant melanoma, Breslow thickness 0.38 mm, Clark's level II, ulceration is absent, regression is present. Example 2: Punch biopsy showed malignant melanoma, Clark's level II, 0.34-mm maximum depth of invasion, with apparent regression. Example 3: Skin biopsy showed lentigo maligna undergoing regression. |
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. For tumors diagnosed prior to 2007:
Regression does not affect CS staging for cutaneous melanoma. "Malignant melanoma, regressing" [8723] is coded only when it is the final diagnosis. Do not use code 8723 for the examples above. According to our pathologist consultant: Melanoma can occasionally undergo "spontaneous" regression -- the tumor can become smaller, and in some cases even disappear. This phenomenon is likely due to an increased immune response on the part of the "host" (person with the melanoma). This is noted occasionally in patients with metastatic disease which gets smaller, or even disappears. We think this is also what has happened in patients who get diagnosed with metastatic melanoma, say in a lymph node, but have no primary tumor, though sometimes give a history of a skin lesion which came and then went away, or a skin lesion which was not submitted for pathological examination. In addition, we (pathologists) occasionally see biopsies which have melanoma as well as the presence of the immune reaction to it, and once in a while, the immune reaction with little or no evidence of residual melanoma. The College of American Pathologists says that regression of 75% or more of the melanoma carries an adverse prognosis.
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. |

20051020 | 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]. |

20051096 | Primary Site--Peritoneum: During a second look staging lap following a diagnosis of serous carcinoma of the left ovary, did the physician correctly indicate a new peritoneum, NOS primary for disease described as an endometrioid adenocarcinoma in a "paracaval cyst" that appears to have arisen in endometriosis? | The primary site is C482 [Peritoneum, NOS]. "Paracaval" means alongside or near the vena cava. Code the site in which the primary tumor originated. |

|
20051059 | 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. |

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. |

20051040 | Primary Site--Sarcoma: What is the correct topography code for a partial lung lobectomy with pathology diagnosis of "pulmonary sarcoma with smooth muscle differentiation"? See Discussion. | Operative report: palpable 2x2cm mass in the mediastinal surface of the rt middle lobe and the contiguous upper lobe together.
Path comment after partial lung lobectomy: In all likelihood this is a malignant process occurring in smooth muscle changes surrounding vessels within the lung versus an undifferentiated epithelial tumor.
ADDENDUM DX: low grade pulmonary sarcoma with smooth muscle differentiation.
Consultant's report concurs with that of the original pathologist's report of malignant neoplasm compatible with smooth muscle origin. |
This case is unique. Assign topography code C493 [Connective, subcutaneous and other soft tissue of thorax]. Based on the information provided, this sarcoma has smooth muscle differentiation and originated in the muscle. Code the primary site to muscle. | 2005 |
|
20051023 | Reportability/Recurrence (Pre-2007)--Bladder: If a patient has had recurrent invasive bladder cancers since 1971, should the latest recurrence in 2003 be SEER reportable because the case has yet to be reported to SEER? |
For tumors diagnosed prior to 2007: Because this 2003 recurrent bladder cancer was initially diagnosed prior to 1973, it is not reportable to SEER. 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. |

20051050 | CS Tumor Size--Breast: Is the largest focus or the total area coded for tumor size in a patient presenting with "scattered foci of DCIS, largest focus measuring 0.6cm. DCIS spans a total area of 2.1cm." | 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 the size of the largest focus in CS tumor size. Code the tumor size for this case as 006 (6mm or 0.6cm). |
