20091025 | MP/H Rules/Multiple primaries--Urinary: How should we handle urinary tract tumors diagnosed before the MP rules went into effect when determining the number of primaries to report primaries? How do you apply rules M5, M6 and M8 when an invasive bladder tumor and other urinary site tumors occur before and after the effective date of these rules? See Discussion. |
Example: Patient with a prior in situ carcinoma of the bladder in 11/89, left ureter papillary transition cell carcinoma in situ diagnosed in 5/05, left renal pelvis papillary transition cell carcinoma in situ diagnosed in 8/07 and invasive bladder carcinoma diagnosed in 3/08. When an invasive bladder tumor and other urinary site tumors occur, do you stop with the bladder at rule M5 and M6 never reaching M8? |
For cases diagnosed 2007 or later: Use the 2007 MP/H rules for urinary sites to assess diagnoses made in 2007-2014. Use the multiple tumors module to compare a diagnosis in 2007-2014 to an earlier diagnosis. For the example above, start by comparing the left renal pelvis diagnosis in 8/07 to the earlier left ureter primary diagnosed 5/05. Start with rule M3. Stop at rule M8. The 8/07 renal pelvis diagnosis is not a new primary. Next, compare the 3/08 bladder tumor to the earlier left ureter primary diagnosed 5/05. Start with rule M3. Stop at rule M5. The 3/08 bladder tumor is a new primary because it is an invasive diagnosis following an in situ diagnosis. Use only the more recent of the two earlier urinary diagnoses for comparison. Do not compare the 2007 and later diagnoses to the 11/89 in situ bladder primary in this case. |

20091027 | MP/H Rules/Multiple primaries--Thyroid: How many primaries should be coded in a patient with a 4/5/08 left thyroid lobectomy diagnosis of follicular carcinoma followed by a 7/25/08 right thyroid lobectomy diagnosis of papillary carcinoma, follicular variant? | For cases diagnosed 2007 or later: Rule M17 under Other Sites applies. These are separate primaries based on their ICD-O-3 histology codes. Follicular carcinoma is coded 8330. Papillary carcinoma, follicular variant is coded 8340. The histology codes are different at the third number. Rule M6 does not apply because these diagnoses are more than 60 days apart. |

20091031 | MP/H Rules/Histology--Thyroid: How is histology coded for a thyroid tumor described as "predominantly papillary carcinoma, tall cell variant, follicular type"? | For cases diagnosed 2007 or later, assign code 8340 [Papillary carcinoma, follicular variant] according to rule H15 for Other Sites. "Predominantly" and "type" indicate specific histologies. "Variant" does not. See rule H13. The histology in this case is papillary and follicular. Tall cell variant is ignored. |

20091040 | MP/H Rules/Histology--Breast: How is histology coded for an "infiltrating papillary carcinoma" of the breast when there is no mention of ductal or adenocarcinoma in the pathology report? | For cases diagnosed 2007 or later, assign histology code 8503 [Papillary adenocarcinoma]. Rule H14 applies. ICD-O-3 code 8050 does not apply in this case. Refer to the numeric listing in ICD-O-3. 8050 is a squamous cell neoplasm. Papillary carcinoma of the breast is NOT a squamous cell neoplasm. It is a neoplasm of the breast parenchyma - ducts, lobules or connective tissue. 8503 is the correct code in this case. |

20091116 | MP/H Rules/Multiple primaries - - Colon: Is a colon tumor reported as "recurrent at the anastomotic junction" just over one year after the diagnosis of a T4 colon tumor to be counted as a new primary? See Discussion. | MP/H rules do not apply to metastasis. However, it has been our experience that pathologists and clinicians tend to use the terms metastatic and recurrence interchangeably. The term "recurrence" is not limited to a tumor recurrence in the same site as a previous malignancy. Sometimes it is obvious that the clinician is using the term recurrence to describe a metastatic lesion. When a "recurrence" is located in tissue that is very different from the original primary site, it is easy to recognize that the intended meaning of the term is metastasis.
Example: Patient with squamous cell carcinoma of the tongue with recurrence in the lung.
However, when the metastatic deposit occurs in similar tissue, it is more difficult to determine the number of primaries.
Example when the term "recurrence" is ambiguous: In April 2008 patient was diagnosed with adenocarcinoma of the ascending colon. At the time of hemicolectomy the tumor was noted to be plastered into the paraduodenal and peripancreatic area. Patient received one dose of adjuvant chemo and then discontinued treatment. In May 2009 the patient was found to have adenocarcinoma in the transverse colon. Per the pathology report the diagnosis for segmental resection at that time showed colonic adenocarcinoma. Tumor location: tumor appears recurrent at anastomotic junction. Abdominal wall mass showed metastatic adenocarcinoma.
One has to wonder if the pathologist found a metastatic nodule at the anastomotic site and called it "recurrent." It is unlikely that the pathologist will compare this specimen to the previous tumor, having already diagnosed it as "recurrent."
|
For cases diagnosed 2007 or later, Rule M4 applies to the example of adenocarcinoma of ascending colon diagnosed in 2008 followed by adenocarcinoma of transverse colon diagnosed in 2009. When a colon resection has taken place, the original primary site is no longer present. A colon resection usually includes a portion of uninvolved colon on either side of the tumor. A tumor diagnosed at the anastomotic junction cannot be located in the same site as the previous tumor. Use of the term "recurrent" in this case is not synonymous with "metastatic." Apply the MP/H rules. | 2009 |

20091042 | Multiple primaries--Hematopoietic, NOS: How many primaries should be coded when a patient has multiple occurrences of plasmacytoma followed by a diagnosis of multiple myeloma? See Discussion. | Example: Patient had a diagnosis on February 2003, plasmacytoma of the sinus; June 2003, plasmacytoma of the alveolar ridge; July 2003, plasmacytoma of the skin; and June 2004, multiple myeloma.
If this represents a transformation of plasmacytomas to multiple myeloma, will the information on multiple myeloma be available for statistical and research purposes? |
For cases diagnosed prior to 1/1/2010:Accession this case as plasmacytoma diagnosed in Feb. 2003. Each of the subsequent diagnoses are not abstracted as new primaries. They are the "same," one primary only, according to the Definition of Single and Subsequent Primaries for Hematologic Malignancies (the tri-fold heme table). The 2003 diagnosis is a classic example of extraosseous plasmacytoma (9734/3). Plasmacytoma and multiple myeloma would be two primaries in the new hematopoietic rules taking effect in 2010. 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. |

20091056 | MP/H Rules/Histology--Ovary: How is histology coded for an ovarian tumor diagnosed as an "ovarian clear cell cystadenocarcinoma"? See Discussion. | Final diagnosis for a resected ovary is ovarian clear cell cystadenocarcinoma. In applying the MP/H rules, rule H16 does not apply because cystadenocarcinoma is not included in Table 2. As a result rule H17 applies. Thus it appears the histology should be coded 8440. Cystadenocarcinoma is a specific histologic type and it is assigned the numerically higher histology code. This result differs from pre-2007 SINQ entry 20041045 that states: Code histology to 8310/3 [Clear cell adenocarcinoma, NOS]. This is consistent with the WHO Classification of Tumours and reflects the current practice of placing less emphasis on "cyst-" prefix for ovarian malignancies. | For cases diagnosed 2007 or later: Assign code 8310 [Clear cell adenocarcinoma] according to rule H13. Ignore "cyst" when determining the histologic type for ovarian malignancies. For this case, the only histology is clear cell. The histologies for the common ovarian epithelial malignancies are serous, mucinous, endometrioid, clear cell, and transitional cell/Brenner. This clarification will be added to the rules in the next revision. |

20091061 | Multiplicity Counter--Head & Neck: How is this field coded when a patient has carcinoma in the same location as a previous primary but it is unknown if there was a disease-free interval? See Discussion. | Patient was diagnosed with squamous cell carcinoma, single tumor of the right true vocal cord in May 2008. Tumor was treated with radiation therapy and chemotherapy. Excision of right vocal cord mass in February 2009 shows squamous cell carcinoma. | Assign code 01 [one tumor only] for the example provided (see discussion). Given the information provided, there is no reason to suspect that the February 2009 diagnosis represents new tumor; therefore, it does not affect the multiplicity counter. It appears that this was the treatment plan for the original diagnosis in May 2008: radiation and chemo followed by excision of the mass. | 2009 |

20091046 | CS Lymph Nodes/CS Site Specific Factor--Melanoma: When CS Lymph Nodes is coded 13, 14 or 15 (codes used when satellite nodule(s) or in-transit metastases are present), why must CS SSF 3 be coded 000 (No lymph node metastasis)? See Discussion. | 3/11/05 Consult - PE: huge exophytic lesion right lower leg (mushroom-type lesion), 6cm. Below that lesion is another ulcerative lesion 2cm. Right upper arm lesion w/ satellite nodule. Note from physician states malignant melanoma on right lower leg metastatic to the left arm/shoulder. No scans done so there is no assessment of the lymph nodes. We coded CS LNS to 13, which captures the satellite nodule, CS SSF3 = 999 and CS Reg Nodes Eval = 0. SEER Edit 216 requires the SSF3 to be 000. SSF 3 is coded 999 as there is no information about the clinical status of lymph nodes. |
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.When CS lymph nodes is coded 13-15, SSF 3 must be coded 000. Follow the instruction in the SSF 3 Note: Use code 000, No lymph node metastases, if ... there are satellite nodules or in-transit metastases, but no regional lymph node metastases, i.e., CS Lymph Nodes is coded 13-15.
For this case, assign CS lymph node code 15 [Satellite nodule(s) or in-transit metastases greater than 2cm from primary tumor WITHOUT regional lymph node involvement or involvement of regional nodes not stated]. The arm lesion is more than 2cm from the leg lesion. |

20091047 | MP/H Rules/Histology--Ovary: How is histology coded for "serous carcinoma, papillary invasive pattern"? | For cases diagnosed 2007 or later, code the histology 8441/3 [Serous carcinoma, NOS]. Use the Other Sites rules. Start with rule H8 and stop at rule H11. "Pattern" is not one of the terms used to identify a specific type (See H16), so papillary is ignored. | 2009 |
