Surgery of Primary Site/Date Therapy Initiated--Head & Neck: Would a biopsy, NOS, that removed the majority of the tumor be used to code these fields? See Description.
Patient underwent biopsy, NOS, of a carcinoma of the tongue. Subsequent glossectomy revealed microscopic focus of residual squamous cell carcinoma.
If the biopsy NOS removed all macroscopic disease, code the date of the biopsy NOS as the date therapy initiated. If macroscopic disease remained following the biopsy NOS, code the glossectomy date as the date therapy initiated.
EOD-Size of Primary Tumor--Breast: How do we code this field when there is a difference between the size of the tumor mentioned in the gross (i.e., macroscopic description) and the comment sections of a pathology report? See Description.
Path Macro Summary states size as 1.5 cm. The path comment states "largest area of tumor seen is 1.5 cm. However, 8 of the nearly contiguous sections are involved with an estimated 2.4 cm area of involvement."
For cases diagnosed 1998-2003: Code the size of the largest area of tumor from the path macro summary. For the example provided, code the size as 015 [1.5 cm]. In this case, the additional sections of tumor described in the path comment do not seem to represent pieces of one larger tumor. The 2.4 cm estimated area of involvement was determined by adding together noncontiguous tumor sections. According to the CAP protocol for breast, Note J "When 2 or more distinct invasive tumors are present, each is separately measured...they are not combined into a single larger size."
Scope of Regional Lymph Node Surgery 2003+/Number of Regional Lymph Nodes Examined--Hematopoietic/Brain/Lymph Nodes/Ill-defined/Unknown: Are codes 9 [Unknown; not stated] and 99 [Unknown; not stated] used respectively for these data items for the mentioned primary sites?
For cases diagnosed Jan 2003 and later:
The Number of Regional Lymph Nodes Examined field is blank for 2003+ cases.
EOD-Lymph Nodes--Head & Neck: If a pre-treatment description of a chain of lymph nodes doesn't meet the criteria for involvement but the post-treatment description of the same chain of lymph nodes does, should those nodes be counted as involved in coding EOD? See Description.
(Primary site = larynx)
9/12/02 CT neck showed right cervical chain adenopathy. After chemotherapy, an 11/18/02 CT soft tissue of neck showed decrease in size by 50% of what was probably necrotic metastatic node to right mandibular angle.
The term "lymphadenopathy" should be ignored when determining involvement of lymph nodes per SEER. In this case, a probable necrotic metastatic node is mentioned in a subsequent CT taken after treatment.
Should lymph node involvement be coded to 9 based on the 9/12/02 CT or coded to 4 because of the mention of a decrease in size of what was probably a metatastic node on the 11/18/03 CT?
For cases diagnosed 1998-2003, code EOD using the best information available. In this example, the post-treatment description of lymph nodes. A post-treatment description of lymph nodes can be used to code lymph node involvement in the absence of disease progression. Pre-operative treatment does not affect lymph node involvement.
Case example: Code lymph nodes as involved (codes 1-4 depending on size and number) based on the later CT report.
Reportability--Appendix: Is an appendiceal carcinoid with one periappendiceal lymph node positive for metastatic carcinoid tumor reportable to SEER? See Discussion.
The patient had an appendectomy followed by a hemicolectomy. No residual carcinoid tumor was identified but there was one lymph node positive for metastatic carcinoid tumor.
Yes, this carcinoid is reportable to SEER. This carcinoid is malignant by virture of the lymph node metastasis. Code the behavior as /3.
Surgery of Primary Site--Head & Neck: Is a composite resection performed for an oral cavity primary coded to 40 [Radical excision of tumor, NOS], 41 [Radical excision of tumor only], 42 [Combination of 41 with resection in continuity with mandibles (marginal, segmental, hemi-, or total resection], 43 [Combination of 41 with resection in continuity with maxilla (partial, subtotal, or total resection)]? See discussion.
Example:
Patient underwent composite resection of left soft palate, tonsillar fossa, medial pterygoid and lateral tongue for a primary of the retromolar trigone. There was no mention of an excision of the mandible; however, the procedure included the application of a mandibular reconstruction plate.
Use surgery codes 40-43 for composite resection of an oral cavity primary. In the case example, code Site-Specific surgery as 42 [Combination of 41 WITH resection in continuity with mandible]. Even though excision of mandible was not mentioned, there was mention of a mandibular reconstruction plate. Since the retromolar trigone is ON the mandible, resection of the mandible is likely.
EOD-Extension--Colon: How is this field coded for an appendical primary when the appendix has ruptured and intrapentoneal fluid is positive?
For cases diagnosed 1998-2003: Code EOD extension as 85 [Metastasis]. Positive intraperitoneal fluid is equivalent to distant metastasis (implantation) for colon, including appendix, primaries.
Reportability/Terminology, NOS--Hematopoietic, NOS: Is "smoldering" multiple myeloma reportable to SEER?
For cases diagnosed prior to 1/1/2010:Yes, "smoldering" multiple myeloma is reportable to SEER as multiple myeloma [9732/3].
According to our pathologist consultant, "smoldering" multiple myeloma would certainly refer to a diagnosed process. Smoldering means the process is progressing, but perhaps slowly, or even at a slower pace than might be expected.
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.
Histology (Pre-2007): How are the following four histologies coded: 1) Adenocarcinoma with focal mucinous adenocarcinoma; 2) Adenocarcinoma with focal areas of bronchioalveolar adenocarcinoma, 3) Mixed infiltrating duct and focal medullary carcinoma, and 4) Mixed infiltrating duct and focal medullary carcinoma? See Description.
1. How do we code colon: Adenocarcinoma with focal Mucinous adenoca? 8140/3 or 8255/3?
2. A lung lesion with predominant adenoca with focal areas of bronchioalveolar adenoca? 8140/3 or 8255/3?
3. Mixed infiltrating duct carcinoma and medullary ca? 8510/3 or 8255/3?
4. Mixed infil duct ca and focal medulary ca? 8510/3 or 8255/3?
For tumors diagnosed prior to 2007:
1. 8140/3, Adenocarcinoma. Mucinous has a specific rule (see sinq 20010075): Include the mucinous component only if it is 50% or more of the tumor. "Focal" is not a majority term.
2. 8250/3, Bronchiolo-alveolar adenoca. Code the more specific histology.
3. 8523/3, Infiltrating duct mixed with other types of carcinoma. Combination of infiltrating duct and another type of carcinoma.
4. 8523/3, Infiltrating duct mixed with other types of carcinoma. Combination of infiltrating duct and another type of carcinoma.
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.
