EOD-Size of Primary Tumor--Breast: How would this field be coded, using the revised and expanded breast code, for a lesion described as "1.3 cm infiltrating ductal carcinoma, associated DCIS?"
For cases diagnosed 1998-2003: Code size of primary tumor as 013. The phrasing suggests that the infiltrating ductal carcinoma measures 1.3 cm. DCIS is also present, but no size mentioned.
EOD-Extension--Kidney: How would this field be coded when the pathology report shows a 20 mm surface neoplasm with smaller yellow metastatic implants on the surface of the kidney?"
For cases diagnosed 1998-2003: Code extension as 10 [Invasive cancer confined to kidney cortex]. Tumor involves the cortical surface of the kidney with separate surface lesions, but does not extend beyond cortex.
Multiple Primaries (Pre-2007)--Breast: For a patient with a remote history of lobular breast carcinoma, would a new diagnosis of lobular breast carcinoma with DCIS be a new primary, even though the physician designates it as recurrent? See Description.
A history of right breast lobular ca in 1991 treated with a partial mastectomy. Diagnosed 3/02 with "recurrent right breast ca" per physician; pathology in 2002 is lobular and DCIS.
Would the DCIS make this a new primary regardless of the physician's designation of 'recurrent' or is this the same primary?
For tumors diagnosed prior to 2007:
Accession as two breast primaries -- the first lobular ca in 1991; the second lobular and DCIS in 2002.
The differing histologies and the length of time between them negate the physician's designation as "recurrent" in this case.
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.
Primary site: How is this field coded for a malignant spindle cell neoplasm in a subcutaneous mass of the right knee? See Description.
The pathology report says: Right knee tumor:
A. discrete subcutaneous mass 3.5x5.2x1.4 cm malignant spindle cell neoplasm (see Comment)
B. A focus of subcutaneous malignant neoplasm is identified in the superior resection margin.
C.All other margins are clear.
The comment mentions that the specimen has been sent to Mayo Clinic and the Mayo clinic consult says, "we still believe that the diagnosis of spindle cell carcinoma is correct. Obviously the differential diagnosis involves melanoma and sarcoma also. The results of the immunoperoxidase stains strongly support the prior diagnosis of a carcinoma."
Code the site to C49.2 [Connective, subcutaneous and other soft tissues of lower limb and hip]. The site is a subcutaneous mass. C49 with 8032/3 will not be impossible following the next updates to the SEER edits.
Hormone Therapy--Hematopoietic, NOS: Is hormonal therapy coded for myelodysplastic syndrome, NOS? See Description.
Patient with myelodysplastic syndrome refused chemotherapy and was treated with high dose steroids. Patient also received Rituxan.
Hormones, such as glucocorticoids and androgens, are generally of little if any benefit to patients with myelodysplastic syndrome, according to the NCI PDQ. Do not code steroids as treatment in the example above.
Date of Diagnosis/Histology (Pre-2007)/Behavior--Melanoma: How are these fields coded when the first shave biopsy finds "what appears to be the top of a melanoma" and a subsequent shave biopsy finds "features consistent with lentigo maligna?"
For tumors diagnosed prior to 2007:
Evaluate each case using all available information, including all pathology reports. Use the date of the first biopsy because it did identify the melanoma. The second biopsy confirmed the histologic type.
According to WHO's Histological Typing of Skin Tumors, lentigo maligna melanoma is similar to lentigo maligna, but has dermal invasion by atypical melanocytes.
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.
Reportability/Behavior Code--Soft Tissue: Is a final diagnosis of a forearm mass diagnosed as "Angiomatoid malignant fibrous histiocytoma [see note]" reportable? The NOTE reads "Angiomatoid malignant fibrous histiocytoma is a low grade borderline lesion with a tendency for local recurrence, but a very low potential for distant metastases." Is behavior /1 or /3?
Angiomatoid malignant fibrous histiocytoma is reportable with a behavior code of /3 according to ICD-O-3. The Final Diagnosis takes precedence over the "note."
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."
Primary Site--Head & Neck: What is the anatomical distinction among tonsillar fossa, tonsillar pillar, and tonsil NOS?
Operative findings describe a right tonsil three times the size of the left tonsil. Tonsil is dissected from the tonsillar fossa. There appeared to be no involvement of tumor below the tonsillar capsule.
The tonsil lies in an indentation called the tonsillar fossa. The tonsillar fossa is bordered on either side by the tonsillar pillars. The tonsillar pillars are part of the supporting structure of the throat opening.
Code C09.9 [Tonsil NOS] as the primary site for the case above.
EOD-Extension--Stomach: How is this field coded for a stomach primary that has metastases to "Sister Mary Joseph's Nodes?"
For cases diagnosed 1998-2003: For a stomach primary, code extension to 70 [Abdominal wall]. Sister Mary Joseph's nodule is a cutaneous umbilical metastasis most commonly from an intra-abdominal primary.
This rare form of cutaneous umbilical metastasis results from spread of tumor within the falciform ligament. The umbilicus is part of the abdominal wall.
