Computed Ethnicity: Should the Name--Alias field be used when generating Computed Ethnicity?
No, "Alias" is not used and should not be used to generate Computed Ethnicity. Computed Ethnicity records the ethnicity based on last name and/or maiden name using a computer algorithm. Alias is not part of the algorithm.
DCO/Multiplicity Counter/Type of Multiple Tumors: How are these fields coded for an unknown primary reported as a DCO case? See Discussion.
Do DCO cases have default values for the Multiplicity Counter and Multiple Tumor Reported as One Primary fields? Should these fields be coded as 88 or 99?
In the data item pages for these fields, there is only a reference to see the NAACCR Death Clearance Manual. However, this manual does not provide an answer. There is guidance to use code 88 for unknown primaries but we noticed that SEER edits skip enforcing this requirement for DCO cases (see SEER IF205 and 206).
For a DCO case reported as an unknown primary [C809], code Multiplicity Counter to 99 [Unknown if multiple tumors; not documented] and Type of Multiple Tumors Reported as One Primary to 99 [Unknown].
Date Multiple Tumors--Prostate: For a prostate biopsy done 10/20/08, both lobes involved with tumor, unknown how many tumors, what would be coded in date of multiple tumors?
In this case, code the date of the biopsy in Date of Multiple Tumors [10202008]. When the number of tumors is unknown, code the date of diagnosis as the Date of Multiple Tumors. This is the date on which it was determined that there were an unknown number of tumors. This instruction will be added to next edition of the MP/H manual.
Date Therapy Initiated--Corpus Uteri: How should this field be coded for an endometrial primary when the patient undergoes a hysteroscopic polypectomy on 01/08/2014 (Surgery code 25), followed by a TAH/BSO on 02/07/2014 (Surgery code 50)? See discussion.
The hysteroscopic polypectomy showed multiple tissue fragments with invasive endometrioid adenocarcinoma. The hysterectomy and BSO removed an 8.2cm endometrioid carcinoma with no extra-uterine involvement.
Record 01/08/2014 for date therapy initiated assuming there was no therapy prior to this date. A polypectomy is a surgical procedure for purposes of coding date therapy initiated.
Date Therapy Initiated/First-Course of Cancer-Directed Therapy Fields/Summary Stage 2000--Prostate: How do you code these fields for a case that received preventative chemo before a definitive cancer diagnosis?
A patient has a "suspicious but not diagnostic" biopsy of the prostate in 09/2002. Doctor said it was not cancer and put the patient on a preventative chemo drug study (GTX-211). The patient returned for a repeat biopsy on 04/2003. Biopsy returned positive for adenocarcinoma. The patient had not been diagnosed when chemo was administered. Can the case be staged using the post-chemo information?
Stage this case the same as all other cases. Use only the information subsequent to the date of diagnosis to code stage and treatment.
The diagnosis date in the example is 04/2003. Do not use information prior to 04/2003 to code stage or treatment. Do not code the preventative chemo as treatment.
Date Therapy Initiated/Reason no treatment--Lymphoma: Is the date of the lymph node biopsy used as the date of treatment if the lymph node biopsy is the first treatment or the only treatment performed? Is the reason for no surgery coded to 0 [Surgery of the primary site was performed]?
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.
Date Therapy Initiated: How would you estimate the date treatment began for a patient who was treated elsewhere and seen only on an outpatient basis at the current facility? See discussion.
July 19th: Retromolar trigone primary was diagnosed.
August 8th note states, "Pt is not a surgical candidate due to multiple medical co-morbidities." Sept 19th note states, "Per Tumor Board, pt has been undergoing radiation for her head and neck cancer." The exact starting date for radiation is not specified.
In the SEER Program Code Manual it states that "In the absence of an exact date of treatment, the date of admission for that hospitalization during which the first cancer directed therapy was begun is an acceptable entry."
If possible, review the radiation treatment summary and outpatient records at the treating facility. If the date treatment began is not stated, look for the completion date and number of treatments, and calculate the first date of treatment.
If the date radiation started cannot be found or calculated, code the month as 09 for the example provided. The determination was made in August NOT to treat with surgery. We know that there was treatment in September.
Date Therapy Initiated: What date should be entered in Date Therapy Initiated when treatment follows a surgical procedure that is not coded under Surgery of Primary Site? See discussion.
If a patient has a surgical procedure that is not coded in the Surgery of Primary Site field and then the patient undergoes additional first course of treatment, such as radiation therapy, how should the Date Therapy Initiated field be coded?
In this example, code the Date Therapy Initiated field to the date of the first surgical procedure. If a SEER edit is triggered, please notify us.
Date of Diagnosis--All Sites: Is it better to estimate the month in the date of diagnosis field using the re-excision pathology report date or code the month to unknown if the only available information is the re-excision date? See discussion.
The only available information is the following pathology report:
On 7/18/00 a wide excision of the primary lesion is done. The report reads, "Lesion approximately 1 cm. Residual superficial spreading malignant melanoma with deepest penetration 4 mm."
Code the Date of Diagnosis field to 07/2000 for this case. Estimate the month of diagnosis whenever possible.
Given the usual delay between the initial excision of the lesion and a wide excision for a melanoma, estimate the month of diagnosis as July.
