Multiple Primaries (Pre-2007)--Trachea/Lung: Would synchronous lesions, of the same histology, diagnosed in the right upper lobe of the lung and trachea be a single primary when the physician feels they are two separate primaries?
For tumors diagnosed prior to 2007:
According to SEER rules, abstract as one primary because although these sites have separate topography codes in ICD-O-3, they were coded to the same three-digit topography code in the first edition of ICD-O (SEER Program Code Manual, 3rd Edition, page 8, Exception B). Simultaneous lesions of the same histology in trachea and lung are one primary. Code the primary site to C399 [Ill-defined sites within respiratory system].
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.
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.
Surgery of Primary Site--Breast: How is this field coded when a patient has a reduction mammoplasty (for macromastia) and within the pathology specimen there is an incidental finding of carcinoma?
Code this reduction mammoplasty to the code which best fits the amount of tissue removed. Read the operative report carefully. Code as a partial mastectomy, skin- nipple- areola-sparing mastectomy, or total (simple) mastectomy. Use text fields to record the details.
Surgery of Primary Site--Breast: How is this field coded for cryosurgery of the breast?
For cases diagnosed 2003 and later: For cryosurgery alone, without a pathology specimen, assign site-specific surgery code 19 [Local tumor destruction, NOS]. Cryosurgery, cryotherapy or cryoablation uses extreme cold to destroy the tumor cells.
If a specimen is sent to pathology use code 20 [Partial mastectomy, NOS] rather than code 19.
If cryosurgery is followed by further surgery, do not use code 19.
EOD-Extension/EOD-Lymph Nodes--Cervix: How do you code these fields when the cancer extended to the pelvic wall and there are periaortic LN metastases?
For cases diagnosed 1998-2003:
Assign extension code 65 for contiguous (direct) extension of tumor from the cervix to the pelvic wall. Assign extension code 85 only if the pelvic wall is involved with discontinuous extension from the cervix; i.e., the cervical tumor spread indirectly (through lymph or vascular channels) to the pelvic wall. Code the pelvic wall involvement in the Extension field and the periaortic lymph node involvement in the Lymph Node field. When the computer does the algorithm, it will look at the periaortic lymph nodes and report the summary stage as distant and the TNM stage group as IV because periarotic nodes are M1. Do not code the periaortic lymph nodes in both fields. This is stage IV, distant disease, due to the periaortic lymph node involvement (EOD lymph nodes code 6).
Histology--Hematopoietic, NOS: When both the path and clinical diagnoses simultaneously reflect reportable diagnoses but one is a worse form of the same disease process, which diagnosis do we code? See Description.
Would this case be coded to RAEB or AML? Bone marrow diagnosis: Hypercellular marrow with profound trilinieage dyspoietic changes. Comment: the features are consistent with RAEB. Clinical diagnosis five days later states: Myelodysplastic syndrome, early acute myelocytic leukemia (likely AML).
For cases diagnosed prior to 1/1/2010:When several diagnoses are made as part of the diagnostic process within two months, code the one with the worst prognosis.
Code the case example as acute myelocytic leukemia.
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.
EOD-Size of Primary Tumor: How is tumor size coded when there is a clinical tumor size, the excisional biopsy pathology report has a tumor size and the resection specimen has residual tumor, but there is no tumor size provided in the pathology report?
For cases diagnosed 1998-2003: Code the EOD-Size of Primary Tumor from the excisional biopsy. If there is some indication that a large amount of tumor was removed at the time of the resection, code the clinical size instead. When both an excisional biopsy and a resection show tumor, code the largest size of tumor reported.
First Course Treatment--Thyroid: Is hormone replacement following total thyroidectomy coded as first course treatment for all thyroid cases?
Code Hormone therapy as 01 [Hormone therapy administered as first course therapy] when thyroid replacement therapy is part of the first course of treatment for follicular or papillary thyroid cancer following thyroidectomy.
Thyroid hormone replacement therapy has a treatment effect on differentiated (follicular and papillary) carcinomas of the thyroid. This treatment effect is not seen for most medullary and undifferentiated thyroid cancers.
Terminology, NOS/Recurrence/Multiple Primaries (Pre-2007): Is the term "residual disease" equivalent to "recurrence"? See Description.
Example 1. Patient underwent excision and re-excision of lentigo maligna in 1998. Final path showed close but negative margins. In 1999 a biopsy of a brown patch (over the scar) in the same location was done. Pathology reported residual lentigo maligna. Is the 1999 melanoma a new primary because it was diagnosed more than two months after the first melanoma and there is no mention of recurrence? Or is the term "residual" another way of saying recurrence?
Example 2. In 1999, patient underwent excisonal biopsy of intraductal carcinoma of the right breast, followed by radiation therapy. In 2000, mammogram showed calcifications in right breast. Biopsy was done with path showing residual ductal carcinoma in situ. There is no mention of recurrence. Is this one or two primaries?
For tumors diagnosed prior to 2007:
According to our pathologist consultant, "residual" disease indicates incomplete eradication of the original disease process. Residual means that the disease process was not completely removed/eradicated in the initial therapy. Therefore cells from the original primary were never completely removed or destroyed.
In each example above, this is not a recurrence per se but rather
progression of disease. Do not abstract the latter diagnosis as a new primary.
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.
Grade, Differentiation--Prostate: Has SEER officially changed the conversion code for Gleason score 7 to grade 3 [poorly differentiated] for cases diagnosed in 2003 or later?
For prostate cases diagnosed in 2003 and forward: convert Gleason score 7 to grade 3 [poorly differentiated].
