MP/H rules/Histology--Breast: How many primaries and what histologies are coded for a left breast when a bi-lumpectomy path reveals one tumor with a microscopic focus of mucinous adenocarcinoma and extensive DCIS and a second .9 cm mucinous adenocarcinoma with extensive DCIS, and the subsequent mastectomy reveals foci of residual DCIS and Paget's disease of the nipple?
For cases diagnosed 2007 or later:
There are two primaries. Primary 1: The two tumors described on the pathology report from the lumpectomy are a single primary using rule M13. Primary 2: Disregard the foci of residual DCIS. Paget disease of the nipple is a separate primary using rule M12.
Primary 1: invasive mucinous adenocarcinoma and extensive ductal carcinoma in situ: Code the histology as 8480/3 [mucinous adenocarcinoma] using rule H27.
Primary 2: Paget disease of nipple: Code the histology as 8540/3 [Paget disease] using rule H14.
Grade, Differentiation: How is grade coded for cases using the FNCLCC (Federation Nationale des Centres de Lutte Contre Ie Cancer) system? See Discussion.
Is FNCLCC a recognized system in the United States? Tongue was the primary site for the case we saw that used FNCLCC.
Do not code the data item Grade based on the FNCLCC grade. You may record the FNCLCC grade in a text field.
CS Site Specific Factor--Prostate: Given that the CS Manual instruction is to code the highest PSA value recorded in the medical record, can a PSA value obtained a year prior to admission be used to code the SSF 1 and SSF2 fields?
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.
The PSA recorded in CS SSF 1 and 2 must be documented in the medical record. Record the highest PSA value prior to diagnostic biopsy or treatment. If the highest PSA value documented in the medical record is from the previous year, record it.
Reportability/Primary Site--Brain and CNS: Is a chondroma, NOS or a chondroblastoma, NOS that occurs in an intracranial site or along the spinal cord reportable? See Discussion.
In ICD-O-3, chondroma and chondroblastoma are site-associated morphologies for bone. If a chondroma or a chondroblastoma occurs along the spinal cord, is this one of those situations where we can be quite comfortable with a default site to bone and not to spinal cord?
Reference: ICD-O-3; Primary Central Nervous System Tumors, NPCR Training Materials 2004; SINQ 20021152
Chondroma, NOS or chondroblastoma, NOS occuring in intracranial sites or along the spinal cord are not reportable.
Chondroma, NOS and chonroblastoma, NOS are benign tumors of the bone itself, not the intracranial contents.
CS Extension--Prostate: Can the phrase "hard, fixed prostate" be interpreted as clinical extracapsular extension and coded to 50 [extension or fixation to other structures]? See Discussion.
Patient had a "hard, fixed prostate" with needle core bx positive for Gleason grade 4+5=9 adenocarcinoma extensively involving gland. PSA was 87.5. Lymphadenectomy showed 3 positive pelvic/obturator lymph nodes. No prostatectomy was done and no physician TNM staging documented.
Do we need a specific clinical description of other organs to which the prostate is fixed in order to code CS Clinical Extension 50, or does the statement "hard, fixed prostate" qualify? If not, how would we code extension for this seemingly advanced cancer?
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.Assign extension code 50 [extension or fixation to adjacent structures] based on the term "fixed." Fixation to a particular structure(s) does not have to be specified in order to use code 50.
Do not use the statement "hard" to determine CS extension.
Primary Site/CS Extension--Lymphoma: How are these fields coded for a lymphoma found in the spleen and retroperitoneal lymph nodes? See Discussion.
A patient presents with a 6-month history of night sweats, low grade fever and significant weight loss. Physical exam reveals no palpable lymph nodes, tender abdomen and splenomegaly. Patient undergoes an exploratory laparotomy with splenectomy and dissection of two retroperitoneal lymph nodes. Spleen and both lymph nodes were positive for small cleaved-cell lymphoma, high grade.
Code the primary site to spleen.
Code CS extension as 22 [involvement of spleen plus lymph nodes below the diaphragm]. This gives it a stage IIS.
Spleen is an extranodal (not extralymphatic) site.
The retroperitoneal lymph nodes are located below the diaphragm.
Multiple Primaries/Histology--Lymphoma/Leukemia: How many primaries and what histologies are coded when a path diagnosis for a cervical/neck mass demonstrates classical Hodgkin's lymphoma on a background of chronic lymphocytic leukemia?
For cases diagnosed prior to 1/1/2010:Hodgkin disease and chronic lymphocytic leukemia are separate primaries according to our current instructions. Abstract and code them separately.
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.
Multiplicity Counter--Thyroid: How is multiplicity counter to be coded for a thyroid cancer presenting as multiple foci? See Discussion.
Thyroidectomy showed papillary thyroid carcinoma. Path diagnosis: tumor focality: multifocal. Path described 3 foci of tumor on each side. The main tumor mass in right thyroid was 1.5 cm. Smaller foci of tumor ranged in size from .1 cm to 1.0 cm. Per guidelines, "we still don't count foci as tumors for the purpose of these rules, even if there is more than one." The 1 cm tumor was probably macroscopic in size. Do we count it in the multiplicity counter? Do we count only the 1.5 cm main tumor mass?
If the number of tumors is known, code the number in Multiplicity Counter. If foci are measured, include them in the multiplicity counter. If the only information available is "multiple foci" assign code 99.
For the case above, code 06 in the multiplicity counter (3 tumors on each side).
Scope of Regional Lymph Node Surgery/CS Reg LN Pos/Exam: How are these fields coded if the operative report does not mention a separate lymph node procedure at the time of the surgery to the primary site? See Discussion.
LUL lobectomy: 1.7 cm apical tumor, diagnosis: moderately well differentiated subpleural squamous cell carcinoma, with involvement of pleural surface. 3 peribronchial LN neg and 2 AP window LNs neg. Stage T2N0.
1. No lymph node dissection or sampling was stated to be done
2. The lobectomy specimen contained the LNs
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.
Code the Scope of Regional LN Surgery, Regional Nodes Positive and Regional Nodes Examined fields using the available information on the case. The lymph nodes can be obtained or biopsied during any procedure within the first course of treatment. A separate lymph node surgery is not required to complete these data items.
Radiation Therapy--Prostate: Is the regional treatment modality XRT best coded to 50 (brachytherapy, NOS), 53 (LDR) or 54 (HDR) when the documentation indicates only "I-125 seeds" to the prostate?
Assign code 53 [Brachytherapy, interstitial, LDR] for seeds to the prostate. Seeds are always low dose because they are left in place and the radioactivity decays over time.
