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.
Multiple Primaries (Pre-2007): Are simultaneous tumors of the rectosigmoid junction and rectum counted as two primaries? See Description.
On the same day in 1998, a patient was found to have a T3 adenocarcinoma of the rectosigmoid junction and an in situ adenocarcinoma in a villotubular adenoma in the lower rectum. These would be the same histology if they are in the same site.
Are C199 and C209 the same site? They are listed in ICD-O-2 (pg. xxxvii) and in ICD-O-3 (pg. 36), but they are not listed in the SEER Program Manual on page 9 as the same site. Is this one primary or two?
For tumors diagnosed prior to 2007:
Abstract two primaries for the example above, according to the main rule on page 7 in the SPCM. Rectosigmoid junction (C19) and rectum (C20) are in different 3-digit ICD-O-3 topography code categories. Rectosigmoid junction and rectum are not included in the exceptions to the main rule and, therefore, do not appear on page 9 of the SPCM.
The table on page 9 is not identical to the table in ICD-O-3. Two site combinations are listed in ICD-O-3, but not in the SEER table: C19 (rectosigmoid junction) and C20 (rectum); C40 (bones of limbs) and C41 (other bones). Abstract multiple tumors in the rectosigmoid junction and rectum as separate primaries. Abstract multiple tumors in the bones of the limbs and other bones as separate primaries.
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.
Behavior Code/EOD-Extension--Colon: Are extension codes 10 [Mucosa, NOS (incl. Intramucosal, NOS)] and 11 [Lamina propria] in situ, in accordance with AJCC stage for this site?
For cases diagnosed 1998-2003: EOD codes 10 and 11 are invasive. SEER, to be compatible with Summary Stage 77 and 2000, calls EOD extension codes 10 and 11 invasive because invasion of the lamina propria is invasion through the lamina propria/basement membrane and therefore invasive.
According to AJCC, the survivial rates for tumors that invade only the mucosa or lamina propria are similar to Tis tumors, so the AJCC classifies them as Tis.
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.
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-Clinical Extension--Liver: How do the segments of the liver described by AJCC Manual correspond to the lobes of the liver described by the SEER EOD Manual? See Description.
CT described hepatocellular ca involvement of the liver with nodules identified in segments 5 and 7. Would EOD-extension be coded to 30 [multiple tumors (one lobe)]?
Segments 2, 3, and 4 correspond to the left lobe of the liver. Segments 5, 6, 7 and 8 correspond to the right lobe of the liver. Segment 1 is the caudate lobe, which has completely different drainage and vascularization, is separate from the larger right and left lobes.
For cases diagnosed 1998-2003: Since segments 5 and 7 are both in the right lobe, assign EOD-extension code 30 for the case above, unless there is mention of vascular invasion. Be sure to record the size of the largest primary tumor.
Tumor size and vascular invasion are the most important factors for AJCC 6th edition staging.
EOD-Lymph Nodes/EOD-Extension: Does extracapsular lymph node extension into adjacent tissue or organs affect EOD coding? See Description.
For a lung primary a PET scan showed marked uptake in the right hilum consistent with metastatic disease. A radical pneumonectomy was performed and the operative findings showed that the pulmonary artery was involved with a mass.
Pathology: Small cell carcinoma in the lung parenchyma. The distal bronchi showed obstructive pneumonitis. There were mets found on 02/05 on the hilar lymph nodes and 00/02 peribronchial nodes. The mets in the hilar nodes extended beyond the lymph node capsule into the pulmonary artery.
For cases diagnosed 1998-2003: Extracapsular lymph node extension does not affect the extent of disease. Code the extent of regional lymph node involvement in EOD lymph nodes.
EOD-Systemic Symptoms at Diagnosis--Lymphoma: Would the description, "three days of typical cold symptoms including congestion, sneezing, chills and advanced difficulty breathing and some fever" qualify as B-Symptoms?
For cases diagnosed 1998-2003:
Use the following criteria to determine whether or not certain clinical findings qualify as "B" symptoms.
1. Fevers. Unexplained fever with temperature above 38 degrees C.
2. Night sweats. Drenching sweats that require change of bedclothes.
3. Weight loss. Unexplained weight loss of more than 10% of the usual body weight in the 6 months prior to diagnosis.
Pruritus alone does not qualify for B classification, nor does alcohol intolerance, fatigue, or a short, febrile illness associated with suspected infections.
The clinical description in the example above does not meet the criteria for B symptoms. Generally, the symptoms in the B category have to occur over an extended period of 7 to 30 days. In this case the fever is explained by "typical cold symptoms" and in addition, three days of fever is not a long enough period.
Grade, Differentiation: Is grade always coded to 4 for a diagnosis of Ewing's sarcoma?
Do not code the ICD-O-3 grade for Ewing sarcoma unless documented in the record.
In the TNM system, grade is required to place Ewing sarcoma into a stage group. For TNM staging purposes, Ewing sarcoma is classified as G4. Do not apply TNM rules to ICD-O coding.
Primary Site/EOD-Size of Primary Tumor--Lung: If the only lung mass described in CXR is a "hilar mass," is the primary site coded to C34.9 [Lung, NOS] or C34.0 [Main Bronchus; incl. Carina]? Also, can the size of the hilar mass be used to code the size of tumor field?
Because the only description available is "hilar mass," code primary site as C34.0.
For cases diagnosed 1998-2003: Use size of mass for EOD-Size of Primary Tumor.
