For cases diagnosed prior to January 1, 2008, enter the date of the lymph node biopsy (excisional biopsy or biopsy NOS) as the Date Therapy Initiated for a lymphoma when the biopsy is the first or only therapy performed.

Code Reason for No Surgery of Primary Site as 0 [Surgery of the primary site was performed] and the biopsy of a lymph node is coded to 25 in Surgery to Primary Site.

Do not code a fine needle aspiration or core needle biopsy in Surgery of Primary Site.

For tumors diagnosed prior to 2007:

The 2005 diagnosis is a new primary. The 1971 site differs from the 2005 site and there are more than two months between the two. Without further information, assign topography code C761 [chest wall]. The pattern of spread, including regional extension, is different for a primary of the chest wall compared to a primary in the breast. Coding the primary site to C761 will group this case with similar cases.

If further information can be obtained, look for old records that describe the extent of the 1971 mastectomy. It is possible that there was breast tissue left on the chest wall. Residual breast tissue is often present following mastectomy (simple, modified, or even radical). New carcinoma can develop in the remaining breast tissue.

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.

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 tumor size as 080 (8cm). Code the largest pretreatment size recorded when there is preoperative systemic treatment.

Assign code 052 [Levator muscle, Skeletal muscle, NOS, Ureter]. The description for this case states periprostatic "striated" muscle tissue. According to our pathologist consultant, "striated muscle in this context is skeletal muscle and the term is being used to differentiate the muscle from smooth (non-striated) muscle." Smooth muscle involvement would be most likely be coded 050 [Extension to bladder neck...] because smooth muscle in a prostatectomy or TURP specimen is usually from the urinary bladder neck.

As of November 2005, Code fundus of bladder to C678 [overlapping lesion of bladder]. Opinions vary regarding the definition of bladder "fundus." However, according to our pathologist consultant, fundus includes posterior, anterior and lateral walls and dome. Fundus does not include the trigone.

A correction to page C-595 of the 2004 SEER manual will be included in the next errata.

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.

For tumors diagnosed prior to 2007:

Assign code 8323 [Mixed cell adenocarcinoma] to "mixed papillary serous and clear cell carcinoma." This is histology coding rule 3 in the 2004 SEER manual under single tumor (page 86). There is no other code for this mixture.

Example 1: 8323

Example 2: 8461 (clear cell is not coded according to Rule 6, page 87, because it is not the majority of the tumor).

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.

For tumors diagnosed prior to 2007:

Code primary site C209 [rectum] and histology 8094/3 [basosquamous carcinoma]. As of 6/9/2003, this is no longer an impossible site/histology combination.

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.

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.
