Diagnostic Confirmation--Hematopoietic, NOS: Is a multiple myeloma diagnosed by an FNA of the lumbar spine (or any other non-bone marrow location) a diagnostic confirmation 1 or 2? See Description.

Does the rule on page 111 of the SEER Program Coding Manual, 3rd Edition, for code 1 apply to myelomas (in the same way it applies to leukemias)?

Assign code 1 [Positive histology] for aspiration of bone marrow. This rule is not limited to leukemias.

Update to Current Manual/Race: How is Race coded when stated as Hispanic and there is no other information? See Discussion.

There appears to be discrepant information in the 2024 (and prior) SEER manual regarding race coding when the patient is described only as Hispanic/Latina. Page 78 tells us to Code as 01 (White) when: b. There is a statement that the patient is Hispanic or Latino(a) and no further information is available

  1. A person of Spanish origin may be any race; however, for coding race when there is no further information other than “Hispanic” or “Latino(a),” assign race as White as a last resort instead of coding unknown.

However, in Appendix D, under "Other Race descriptions", there is a statement that "If no further information is available, code as 99 Unknown." The list includes "Hispanic."

Assign code 01 (White) for Hispanic when there is no additional information. It is listed in the 2024 SEER Manual, Race Coding Instruction 6.b.i. and in Appendix D for code 01. We will remove Hispanic from the list in Appendix D under code 99 in the next version of the manual.

Tumor Size--Clinical/EOD 2018--Prostate: How is Tumor Size--Clinical coded when there is an incidental finding of prostate cancer on prostatectomy for another reason? See Discussion.

SEER*RSA states EOD Primary Tumor should be coded to 800 for an incidental finding of prostate cancer on prostatectomy for other reasons.

The SEER Manual states to assign code 000 for Tumor Size--Clinical when EOD Primary Tumor is coded to 800; however, the definition for Tumor Size--Clinical indicates clinical classification is composed only of diagnostic workup prior to treatment.

If there is no clinical workup for an incidental finding of prostate cancer, code 000 does not seem appropriate (does not meet criteria for clinical classification). Code 999 seems more appropriate for incidental findings during surgery for other reasons. The SEER Manual does not provide this exception in the current instruction.

Assign code 000 for Tumor Size--Clinical when EOD Primary Tumor is coded 800 (No evidence of primary tumor). Code 000 indicates no tumor was found since there was no clinical workup to identify this incidentally found cancer. This is a special instruction for cases coded 800 in EOD Primary Tumor. Text fields can be used to record details.

First Course Treatment/Neoadjuvant Therapy--Melanoma:  How are the three Neoadjuvant Therapy data items (Neoadjuvant Therapy, Neoadjuvant Therapy--Clinical Response, Neoadjuvant Therapy--Treatment  Effect) coded when a patient is diagnosed with melanoma in the lymph nodes with no primary skin site identified? The physician gives immunotherapy as neoadjuvant therapy with planned and carried out surgical resection of involved lymph nodes following completion of immunotherapy. There is no "planned definitive surgical resection of the primary site" as no primary site was found,

Assign code 0 to each of the three Neoadjuvant Therapy data items in this situation.

We will add an example to the coding instructions for these data items in the next release of the manual.

20081097 DCO/Systemic Treatment, Surgery Sequence: How does SEER want systemic treatment/surgery sequence coded for a DCO case?

Assign code 0 [No systemic therapy and/or surgical

treatment] as a default for DCO cases.

20071116 Behavior--Bladder: What behavior code is used for a TURB path specimen diagnosis of "non-invasive urothelial carcinoma, no muscle found, depth of invasion cannot be assessed" when the clinician stages the case as Ta? See Discussion. The SEER site specific coding module for bladder says, "If the only surgery performed is a TURB and if it is documented that depth of invasion cannot be measured because there is no muscle in the specimen, code the behavior as malignant and not in situ."

Assign behavior code 2 [in situ] based on the physician's stage Ta.

When no other information is available and the TNM designation is not available, use the instructions on page C-844 in Appendix C of the 2007 SEER manual as a default.

EOD/Summary Stage--Eye: How is stage coded for a patient with extranodal non-Hodgkin lymphoma involving bilateral choroids (single focus, both sites) and no lymph node involvement? Since the eyes are a paired site, is this two separate extranodal sites? If so, there are no Summary Stage or EOD tumor codes that best fit this scenario.

Assign as Stage IV as recommended by our expert hematological oncologist. This is a rare occurrence and this type of presentation does not fit the definition of intraocular extension. Stage IV is probably the best stage for this type of presentation, since there are two extranodal organs involved, even though they involve a bilateral site.

EOD Primary Tumor: 700

SS: 7 (Distant)

Summary Stage 2000--Lymphoma: How is SEER SS2000 coded for an ocular adnexal lymphoma when it extends from the primary site to adjacent sites that are still orbital structures? See Discussion.

In this case, the lymphoma arose in the posterior orbit and the primary site was coded as C696 (orbit, NOS). The mass directly extended to at least one "adjacent" site, the lacrimal gland. Should SS2000 be coded to 1 (localized) or 5 (regional, NOS) when an ocular adnexal lymphoma arises in the posterior orbit and extends to involve the lacrimal gland? Although both the posterior orbit and the lacrimal gland are parts of the orbit, they have separate ICD-O-3 topography codes. Should extension to multiple sites within the orbit be classified as localized disease?

The issue is what constitutes "adjacent" structures for a tumor that arises in the orbit. In an article published by the Indian Journal of Opthamology it states, "According to the Ann-Arbor staging system, lymphoma confined to the orbit is designated as Stage I, involvement of adjacent structures (sinuses, tonsil and nose) makes it Stage II." Does SEER agree with this definition of "adjacent" structures? Or are the lacrimal gland, ciliary body, retina, conjunctiva and/or choroid "adjacent" structures for a lymphoma stated to arise in the posterior orbit?

Assign SEER SS2000 code 5 (Regional, NOS) for a lymphoma of orbit extending to lacrimal gland. In SEER SS2000, this is Stage IIE: Direct extension to adjacent organs or tissues.

2024 SEER Manual/Primary Site--Breast: Is Primary Site coded as C504 or C501 based on the Solid Tumor Rules and the SEER Manual Breast Coding Guidelines? The pathology report reads "Right Breast 10:00 1 cm from the nipple."

Codes C502-C505 take priority over code C501. The description for C501 in the Solid Tumor Rules has "Area extending 1 cm around areolar complex."

Assign Primary Site code C504 based on the location in the upper outer quadrant of the right breast, 10 o’clock, as opposed to code C501, around the areolar complex. The 2024 SEER Manual Breast Coding Guidelines advise that C502 - C505 are generally preferred over C501 when there is no other way to determine the subsite.

SEER Manual/Laterality--Kaposi Sarcoma:  If both arms are involved with Kaposi sarcoma and no other sites, how is laterality coded?  See Discussion.

Per Solid Tumor Manual Other Sites Rule M6, despite the number of areas of involvement, any presentation of Kaposi sarcoma is always a single primary. The primary site is skin using the Kaposi Sarcoma for All Sites Coding Guidelines (Appendix C, 2023 SEER Manual). 

Does SEER Program Coding and Staging Manual Laterality Coding Instruction #4 preclude the use of code 4 [Bilateral involvement at time of diagnosis...] if a patient presents with KS involvement of only both arms or only both sides of the face?

Assign Laterality code 4 (Bilateral involvement at time of diagnosis, lateral origin unknown for a single primary) in the situations you describe. Skin of upper limb and shoulder and Skin of other and unspecific parts of the face are listed as paired organs in the table Sites for Which Laterality Must Be Recorded In the 2023 SEER Manual.
