Immunotherapy/Chemotherapy: Are monoclonal antibodies, such as Avastin and Erbitux, coded as immunotherapy or chemotherapy? See Discussion.
In review of the "FDA-approved oncology agents not listed in SEER Book 8" provided in 5/02, it appears "monoclonal antibodies" are coded as immunotherapy.
Code Avastin and Erbitux as chemotherapy because both of these drugs are growth inhibitors. Code growth inhibitors (cytostatic agents) as chemotherapy. Do not assume that monoclonal antibodies are coded as immunotherapy.
Immunotherapy/Radiation Therapy: Is I-131 labeled immunoglobulin coded as immunotherapy or radiation therapy?
Code treatment with I-131 labeled immunoglobulin as radiotherapy. The primary action is radiotherapeutic. Radioimmunotherapy (RIT) uses antibodies to deliver the radiotherapy to the site of the tumor.
Laterality--Breast: Should laterality be coded to 9 [Paired site but no information concerning laterality] or to the side with the positive lymph nodes for a case in which no breast mass is found but positive axillary lymph nodes are found on only one side?
Code laterality of the primary site to the side with the positive nodes when there are unilateral positive nodes and the laterality of the primary site is otherwise unknown.
Laterality--Heme & Lymphoid Neoplasms: Is laterality coded to 0 [not paired] for all lymphoma cases including paired sites (e.g., breast, lung)?
Laterality coding for lymphomas is based on the primary site not histology. Laterality describes the side of a paired organ or side of the body on which the reportable tumor originated. Determine whether laterality should be coded for each primary.
Laterality coding instructions are located in the SEER Program Coding and Staging Manual. See pages 68-70 in the 2013 manual,
Laterality/Multiple Primaries (Pre-2007)--Ovary: Are ovarian primaries with bilateral involvement always coded to laterality 4 (bilateral)? See Description.
Example: "Right ovary with mass replacing majority of ovarian tissue consistent with serous adenoca. Lt ovary with foci of adenoca." No specific statement of primary. Can we assume that the malignancy originated in the right ovary since it is more extensively involved or should laterality be coded 4 because both ovaries have tumor?
For tumors diagnosed prior to 2007:
If one ovary is listed as the primary site, code laterality to that ovary. The example above is one of those times when you would code to the single ovary. The issue of one or both ovaries being involved is handled in staging.
Abstract the example above as a single primary with code 1 [Right] for laterality.
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.
MP/H Rules--Bladder: Should an invasive urothelial carcinoma of the bladder diagnosed in 2004 followed by an in situ urothelial carcinoma of the ureter diagnosed in 2008 be reported as multiple primaries per the three-year guideline in Rule M7 or a single primary per the subsite guideline in Rule M8? See Discussion.
Rule M7 states, "Tumors diagnosed more than three (3) years apart are multiple primaries." Should this rule be modified to say, "Bladder tumors diagnosed more than three (3) years apart are multiple primaries"? Does Rule M7 apply to only bladder tumors or does this rule apply to tumors in any of the urinary sites similarly to Rule M8 which states, "Urothelial tumors in two or more of the following sites are a single primary: Renal pelvis (C659) Ureter (C669) Bladder (C670-C679) Urethra/prostatic urethra (C680)"?
For cases diagnosed 2007 or later, Rule M7 pertains to renal pelvis, ureter, bladder and other urinary sites as defined by the topography codes listed in the header of these rules.
An invasive urothelial bladder tumor followed more than three years later by an in situ TCC of the ureter are reported separate primaries. Rule M8 applies when the tumors in these sites are diagnosed within three years of each other.
MP/H Rules--Breast: How many primaries should be abstracted when a patient has a mass at 6:00 that showed poorly differentiated ductal carcinoma and a hypoechoic nodule at 9:00 that was excised with no real tumor present there though path showed angiolymphatic invasion by carcinoma throughout the entire specimen? See Discussion.
Palpable mass in right breast at 6:00. Path stated 'poorly differentiated ductal carcinoma with extensive necrosis and extensive angiolymphatic invasion. Focal high grade comedocarcinoma (1%)'. Another hypoechoic nodule was seen at the 9:00 position. This mass was excised from surrounding tissue. This mass was more like an inflammatory mass; there was no real tumor present there. Path report stated "Breast mass 9:00 excisional biopsy - angiolymphatic invasion by mammary carcinoma throughout the entire specimen."
Is this two primaries because of the two different histology codes: 8500 and 8010?
For cases diagnosed 2007 or later, abstract as a single primary using rule M3 (a single tumor is always a single primary). There was one tumor present according to the information provided. The second specimen was not a separate tumor ("There was no real tumor present there").
MP/H Rules--Breast: Is a 2008 invasive ductal carcinoma counted as a new primary when it follows a 2005 invasive lobular carcinoma diagnosed in the same breast? See Discussion.
The patient has invasive lobular breast carcinoma excised in 2005. She returns in 2008 with a new invasive ductal carcinoma tumor same breast. Following MP/H rules, M10 seems to apply, which states this is still a single primary. Does this mean that this invasive ductal carcinoma is ignored and the patient remains in the registry with only a lobular carcinoma primary?
For cases diagnosed 2007 or later:
Rule M10 applies. The 2008 diagnosis is not a new primary.
The abstract for the 2005 diagnosis should be annotated to include the new information.
MP/H Rules--Breast: Is inflammatory breast cancer always one primary per lifetime? Or is a subsequent inflammatory breast cancer a second primary if diagnosed more than five years later?
For cases diagnosed 2007 or later, a diagnosis of inflammatory breast cancer more than five years after a previous diagnosis of inflammatory breast cancer is a separate (new) primary. See rule M5 in the Breast Multiple Primary Rules.
