#2: Invasive ductal carcinoma, well-differentiated, 1.0cm (12:30 o'clock). -Minor component of DCIS, low-grade? See Discussion.
In the MP/H Rules, Table 1 lists apocrine as a type of intraductal carcinoma. Apocrine does not appear in Table 2, the list of specific duct carcinomas. If Apocrine is a type of ductal carcinoma, then Rule M11 would make this a single primary. If it is a single primary, what is the histology?
For cases diagnosed 2007 or later:
Using rule M11, there is one primary in the left breast. Apocrine is a specific duct carcinoma. To make this more clear, apocrine will be added to Table 2 in a future revision.
To code the histology, go to the multiple tumors module and start with rule H20. Stop at rule H29 and code the histology with the numerically higher ICD-O-3 code, 8500/3.
First course treatment: Is subsequent treatment with R-ICE first course or second course therapy if the patient underwent ABVD x2 cycles and subsequent imaging showed no response to treatment and evidence of progression [new adenopathy] for a lymphoma case? See Discussion.
Patient was initially diagnosed with Hodgkin Lymphoma, Nodular Sclerosing on 3/3/06.
Patient received ABVD x 2 cycles. Had disease reassessed in May, 2006, no response to treatment, showed evidence of progression (new adenopathy). Patient's pathology from 3/06 was sent for consult: Diagnosis was Hodgkin with some overlapping features of B-cell Non Hodgkin Lymphoma. Treated 5/18/06 with R-ICE FOR NHL.
The R-ICE treatment in this case is not part of the first course. Documentation of treatment failure and/or disease progression signifies the end of the first course of treatment.
MP/H Rules--Breast: What histology code is used for lobular with focal ductal features? Do we ignore the focal features and code as lobular or do we use the combination code for duct and lobular?
For cases diagnosed 2007 or later, use rule H14 and assign code 8520 [lobular]. Ignore histologies described as "focal," "foci," or "focus." This instruction will be added to the next version of the MP/H manual.
CS Extension--Corpus uteri: Can a suspicious cytology be used to code extension? See Discussion.
Endometrial primary confirmed by biopsy on 10/26/06. Pelvic washing on 11/14/06 was 'suspicious for malignancy.' Resection path the same day stated the primary tumor invades the inner 1/3 of the myometrium.
Can we use the pelvic washing cytology & code CS extension 61 or should CS extension be coded 12?
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 extension code 61 [cancer cells in peritoneal washings] for the case described above.
"Suspicious" is listed as a term indicating involvement. There is no exception noted for cytology reports. See page 122 of the 2007 SEER manual.
Primary Site/CS Extension--Lymphoma: How are these fields coded for an epidural lymphoma that extends into the bone marrow of the adjacent vertebral body?
For cases diagnosed prior to 1/1/2010:After verifying that the lymphoma originated in the epidural space, code to C729 [nervous system, NOS (epidural)]. This is a rare type of extranodal lymphoma.
Assign CS extension code 80 for lymphoma with bone marrow involvement.
For cases diagnosed 1/1/10 and later, 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.
Scope of Regional Lymph Node Surgery/CS Reg LN Pos/Exam: How are these fields coded if the operative report does not mention a separate lymph node procedure at the time of the surgery to the primary site? See Discussion.
LUL lobectomy: 1.7 cm apical tumor, diagnosis: moderately well differentiated subpleural squamous cell carcinoma, with involvement of pleural surface. 3 peribronchial LN neg and 2 AP window LNs neg. Stage T2N0.
1. No lymph node dissection or sampling was stated to be done
2. The lobectomy specimen contained the LNs
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 Scope of Regional LN Surgery, Regional Nodes Positive and Regional Nodes Examined fields using the available information on the case. The lymph nodes can be obtained or biopsied during any procedure within the first course of treatment. A separate lymph node surgery is not required to complete these data items.
Reportability--Breast: Is a final path diagnosis of "phyllodes tumor, borderline (malignant, low grade)" reportable if the comment states "Features favor the diagnosis of a borderline phyllodes tumor (or also called malignant phyllodes tumor of low grade)"?
No, borderline phyllodes tumors (PT) are not reportable. The ICD-O-3 code is 9020/1. According to the WHO Classification of Tumours of the Breast and Female Genital Organs, borderline PT's are also called low grade malignant PT's.
Reportability--Brain and CNS: Are schwannomas of the spinal cord reportable when they are intradural? See Discussion.
The CNS guidelines basically indicate that schwannomas must all come from peripheral nerves and thus are not reportable when they are on the spinal cord. However, the COC Inquiry 18174 & 18068 states that schwannomas occasionally will develop inside the dura (intradural) on the spinal cord and would be reportable.
According to an expert consultant, schwannomas must be derived from Schwann cells which are not a part of the CNS. All schwannomas come from peripheral nerves. Benign and borderline tumors of the peripheral nerves (C47_), including peripheral nerves along the spinal cord, are not reportable.
Multiplicity Counter: Are in situ tumors diagnosed more than 60 days after invasive tumors of the same site and histology included in the Multiplicity Counter?
If an in situ tumor following an invasive tumor is a single primary according to the multiple primary rules for that particular site, include the in situ and the invasive tumors in the multiplicity counter.
Reportability/Diagnostic Confirmation: If a diagnosis based solely on positive flow cytometry is reportable even if a bone marrow biopsy is negative, how is diagnostic confirmation coded?
For cases diagnosed prior to 2010
The case is reportable if a recognized medical practitioner says the patient has cancer.
A flow cytometry alone is not diagnostic but it may be supported by either a positive bone marrow or a clinician's statement. If the clinicians statement is based only on flow cytometry, code diagnostic confirmation to 8 [Clinical diagnosis only].
