CS Extension/CS Mets at Dx--Pineal Gland: In Collaborative Stage, how is positive cerebral spinal fluid coded?
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 CS Mets at DX code 40 [Distant metastases] for a pineal gland primary with positive cerebral spinal fluid.
CS Lymph Nodes--Breast: Is it better to code to 26 [Stated as N1, NOS] or 28 [Stated as N2, NOS] instead of 60 [Axillary/regional lymph nodes, NOS; Lymph nodes, NOS] when the only information in the medical record is the TNM N1 or N2 physician stage?
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.
Yes. When the only indication of lymph node involvement is the physician's N category from TNM, code the numerically lowest equivalent CS Lymph Nodes code for that N category.
In the breast schema, CS Lymph Nodes code 26 corresponds to N1, NOS and code 28 corresponds to N2, NOS.
Reportability/Multiple Primaries (Pre-2007)/Histology--Anus: How many primaries exist if an 11/7/03 anal lesion presents with poorly differentiated adenocarcinoma with signet ring features and extensive mucin production and the 1/9/04 wide excision has adenocarcinoma and Paget disease (intraepidermal adenocarcinoma) extends to skin margin?
For tumors diagnosed prior to 2007:
This is a single primary: the adenocarcinoma with the Paget representing intraepithelial extension of the process. Tumor cells can invade from their place in the epithelium into the underlying stroma either at the primary site, or at their extension site (skin).
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.
Primary Site/CS Extension/CS Lymph Nodes--Lung: How are these fields coded for untreated lung primaries when only limited information is available from scans, bronchoscopies and biopsies? See Discussion.
3/13/04 CT scan Chest: extensive mediastinal, subcarinal, rt hilar lymphadenopathy; separate tumor mass in medial rt lung
3/16/04 Bronchoscopy: RLL/RML completely obstructed with extrinsic compression. Impression: CA of lung with hilar adenopathy.
Bronchial wash: PD non small cell CA
Bx RLL: up to 0.2 cm PD Adenocarcinoma c/w primary lung CA.
Treatment not recommended.
Expired 5/03/04.
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 primary is in the right lung according to the available information.
Assign CS extension code 10 [Tumor confined to one lung]. The only information on extension is that there is a tumor in one lung.
Assign CS Lymph Nodes code 20 [Mediastinal and subcarinal lymph node involvement]. The CT scan confirms mediastinal and subcarinal lymphadenopathy.
Code tumor Size as 999 [Unknown]. "Completely obstructed" is not a size. Do not code the size of the biopsy specimen.
Collaborative Staging--Hematopoietic, NOS: Which Collaborative Staging schema is used for a connective, subcutaneous and soft tissue primary of the pelvis [C495] with the morphology of Langerhans cell sarcoma [9756/39]? See Discussion.
On page C-411 of the SEER manual for the connective, subcutaneous, and other soft tissues schema it lists exceptions for certain morphologies and the above is not listed as an exception. On the Hematopoietic scheme it lists the above morphology.
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.Use the hematopoietic schema on page C-709 of the 2004 SEER manual. The histologically defined schemas have priority over the site schemas when both apply. See page 115 of the 2004 SEER manual.
The morphology codes listed on page C-411 pertain to the SEER Site Specific Guidelines.
Chemotherapy/Immunotherapy: Which drugs changed categories when SEER*Rx came out?
Please refer to http://seer.cancer.gov/tools/seerrx/
SEER*Rx is effective for cases diagnosed 1-1-2005 and forward. It replaces all previous references. It is neither required nor recommended that cases treated prior to 2005 be recoded.
The following drugs in the 5/17/02 Book 8 update changed from immunotherapy to cytostatic chemotherapy in SEER*Rx:
alemtuzumab/Campath
bexarotene/Targretin
bevacizumab/Avastin
bortezomib/Velcade
pegaspargase/Oncaspar
rituximab/Rituxan
trastuzumab/Herceptin
asparaginase
The following drugs may have been coded as monoclonal antibodies but are radioisotopes in SEER*Rx:
epratuzumab/LymphoCide
ibrituzumab
tiuxetan/Zevalin
tositumomab/Bexxar
Any other monoclonal antibodies either remained as monoclonal antibodies or it was a local decision to code them as immunotherapy.
There were no drugs that changed from chemotherapy to immunotherapy.
Multiple Primaries (Pre-2007)/Recurrence--Cervix: How many primaries should be abstracted if a patient had a diagnosis in 1998 of adenocarcinoma in situ of the cervix treated with a total hysterectomy and a July 2004 vaginal mass biopsy with a diagnosis of invasive adenocarcinoma that is consistent with an endocervical primary?
For tumors diagnosed prior to 2007:
Abstract the July 2004 diagnosis as a new endocervical primary. Abstract an invasive cancer in the same site more than two months after an in situ cancer as a new primary. Residual cervical tissue is present following a hysterectomy.
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.
CS Eval--Colon: When the surgical resection occurs after radiation or chemo, how is the tumor size/extension evaluation field coded when there is no mention of the tumor size or extension in the surgical resection pathology report? See Discussion.
6/30/04 CT Scan abd/pelvis: 7.5x7.2 cm large rectal mass with l cm nodular densities in perirectal region probably adenopathy; irregularity of perirectal soft tissue which could be due to tumor infiltration. 7/26/04 Patient has radiation therapy and 5FU. 10/19/04 LAR: MD Adenoca rectum with regional node mets (3/8).
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.Based on the information provided above, code CS Tumor Size and Extension from CT scan. Code CS TS/Ext eval 5 [Surgical resection performed with pre-surgical treatment...size based on clinical evidence].
Code CS lymph nodes using information from resection. Code CS Reg Nodes eval 6 [Regional LN removed...with pre-surgical treatment...based on pathologic evidence].
Histology (Pre-2007)--Melanoma: How is histology coded if the final diagnosis is "melanoma" and only in the comment section of the pathology report is there an indication of "Type: Lentigo Maligna. Cell Type: Small Cell"?
For tumors diagnosed prior to 2007:
Code the histology as 8742 [lentigo maligna melanoma]. Code the specific histologic type, even if stated only in the comment section.
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.
2004 SEER Manual Errata/CS Tumor Size--Can the Determining Descriptive Tumor Size information, on page 6 in the SEER EOD Manual, January 1998, be used to code descriptive tumor size in Collaborative Stage?
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.
Use the instructions in the CS Manual, Appendix 1, page 62. This information will be added to the 2004 SEER manual in the next update.
Do not use the Determining Descriptive Tumor Size information from EOD for CS Tumor Size.
