Primary Site/CS Extension--Lymphoma: How are these fields coded for an epidural lymphoma that extends into the bone marrow of the adjacent vertebral body?
For cases diagnosed prior to 1/1/2010:After verifying that the lymphoma originated in the epidural space, code to C729 [nervous system, NOS (epidural)]. This is a rare type of extranodal lymphoma.
Assign CS extension code 80 for lymphoma with bone marrow involvement.
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.
Histology--Head & Neck: How do you code histology for a myofibroblastic sarcoma of the soft tissue of the head and neck?
Assign code 8825/3 [Myofibroblastoma, malignant]. According to the WHO Classification of Soft Tissue Tumors, "Low grade myofibroblastic sarcoma represents a distinct atypical myofibroblastic tumor often with fibromatosis-like features and predilection for the head and neck." Also called myofibrosarcoma.
MP/H Rules: Does the presence of metastases affect the application of the MP/H rules? See Discussion.
Single lung tumors presenting in each lung but the patient also presents with bone mets? Would rule M6 apply? Or do the bone mets represent additional tumors?
For cases diagnosed 2007 or later, the MP/H rules do not apply to metastases. Ignore metastases when applying the rules.
For the case above, use rule M6 and abstract as two primaries (right lung and left lung). The bone mets are ignored.
MP/H Rules/Multiple primaries--Lung: Should a subsequent primary be abstracted using rule M8 for a patient diagnosed in January 2000 with adenocarcinoma of the right upper lung if the patient initially sought alternative therapies and presented in September 2007 for a right upper lobe lung mass with extension into the mediastinum, mediastinal lymph node mets and a pericardial effusion? See Discussion.
After more than seven years, the patient in this case decided to proceed with the originally suggested standard therapy. Is this a multiple primary case because the tumors are "diagnosed" more than 3 years apart? Or should we assume this is further progression of the 2000 case because it was originally only treated with alternative therapies? The clinician in this case indicates the patient is being referred for treatment to the right upper lung originally diagnosed in 2000.
For cases diagnosed 2007 or later:
Do not abstract a 2007 primary for this case. From the information provided, there is disease progression/extension and lymph node metastasis in 2007; but there are no new lung tumors in 2007. Therefore, the 2007 MP/H rules do not apply.
MP/H Rules--Fallopian Tube: How many primaries are to be abstracted for a case in which a bilateral fallopian tube primary is staged T1c by the pathologist? See Discussion.
A bilateral fallopian tube primary was coded to multiple primaries. However, the AJCC staging for T1b says, "tumor limited to both tubes"
and T1c "tumor limited to one or both tubes." The tumor is T1c according to the pathologist. Is this two T1c primaries or one?
For cases diagnosed 2007 or later, abstract as two primaries using Other Sites rule M8.
This issue will be reviewed during the next update to the MP/H rules.
First course treatment/Histology--Lymphoma: What treatment, if any, is coded for a patient with methotrexate induced lymphoma when the treatment plan is to take the patient off methotrexate? Also, is there a specific histology for drug induced lymphoma? See Discussion.
Diffuse Large B-cell Lymphoma of soft palate & nasal septum, methotrexate induced, in 5/07. Patient was taken off methotrexate with complete resolution of disease. No other treatment was given. Patient was on methotrexate for treatment of rheumatoid arthritis.
For cases diagnosed prior to 1/1/2010:Treatment: Code the treatment fields to 00 [not done] in this case.
Document the discontinuation of methotrexate for rheumatoid arthritis in a text field.
Histology: Assign code 9680/36 [Malignant lymphoma, large B-cell, diffuse, NOS]. There is no specific histology code for therapy-related lymphoma.
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.
CS Extension: How is CS Ext coded for the following?
Rretroperitoneal primary
Cystic mucinous tumor with intraepithelial carcinoma
There is no CS Extension code for intraepithelial ca in the retroperitoneal scheme.
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.According to the American College of Surgeons I & R system, assign code 10 [confined to site of origin] for intraepithelial carcinoma of the retroperitoneum.
MP/H Rules--Lung: In reference to lung, SINQ 20071028 states "'nodule' is not an equivalent term for tumor, mass, lesion, or neoplasm." However, slide 5 for the MPH lung section of "Beyond the Basics" states "we use the words 'mass, nodule and lesion' interchangeably." Which is it?
For cases diagnosed 2007 or later:
For the purpose of applying the Lung MP/H rules, the word "Nodule" can be used interchageably with "Tumor," "Mass," "Lesion" and "Neoplasm." HOWEVER, this does NOT apply to casefinding or staging.
This revision will be added to the next version of the MP/H rules. Sinq question 20071028 will be revised.
Reason no surgery of primary site/First course treatment: If the Reason no Surgery of Primary Site field is coded as 7 (refused), must the other treatment options (radiation, chemo, hormone) also be coded as 7? See Discussion.
Coding instruction #5 in the SEER manual states: "Assign code 7 (refused) if the patient refused recommended surgery or made a blanket statement that he/she refused all treatment."
Refused [code 7] means this modality was specifically recommended by the physician and the patient refused. If two treatment alternatives were offered and surgery was refused, code Reason no surgery of primary site 1 [Surgery of the primary site was not performed because it was not part of the planned first-course treatment].
Refusal of surgery does not necessarily mean that all treatment was refused. Coding Surgery of Primary Site as "refused" does not affect the coding of Radiation, Chemotherapy, Hormone Therapy, etc.
