Histology (Pre-2007)--Colon: What code is used to represent the histology "adenocarcinoma arising in a papillary adenomatous polyp"? See discussion.
Is "adenocarcinoma arising in a papillary adenomatous polyp" equivalent to adenocarcinoma in a villous adenoma [8261/3] or adenocarcinoma in an adenomatous polyp [8210/3]?
For tumors diagnosed prior to 2007:
Code the Histology field to 8261/3 [adenocarcinoma in a villous adenoma]. In describing colon polyps, papillary and villous are equivalent terms.
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.
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.
EOD-Size of Primary Tumor--Lung: Can tumor size of 002 [Malignant cells present in bronchopulmonary secretions] be used when there is a lung mass seen but the diagnosis is from a positive bronchopulmonary secretion?
For cases diagnosed 1998-2003:
EOD-Size of Primary Tumor code 002 [Malignant cells present in bronchopulmonary secretions] is used only when there is no visible primary lung tumor and bronchopulmonary secretions are positive for lung malignancy.
Even if the diagnosis was made by cytology of broncho-pulmonary secretions, if there is a visible mass, code the size of the mass if known, code 999 if size is unknown.
Ambiguous Terminology: Should SEER's lists of ambiguous terminology be modified to reflect how pathologists and radiologists actually use these terms? See discussion.
Pathologists and radiologists say the term "suggestive" is used to describe a lesion that may be malignant, and the term "suspicious" is not used to describe lesions that may be malignant. According to the physician director of our Breast Center the FDA governs the use of terminology, and the term "highly suggestive" instead of "highly suspicious" must be used if there is a greater chance that a mass is malignant.
We recognize that the way clinicians and registrars speak is often different, and that the differences vary from region to region.
Our Medical Advisory Board reviewed the lists of ambiguous terminology before they were included in the third edition of the SEER EOD and the SEER Program Coding and Staging Manual 2004. Since that time, specific terminology has been mandated for describing mammography results. We know some of these terms are discrepant with our ambiguous terminology list.
As of 2007, the standard setters (CoC, NPCR, SEER and CCCR) all use the same ambiguous terminology list. Changes to the list must be approved by the NAACCR Uniform Data Standards Committee.
Other Therapy: What code is used to represent "gene" therapy? See discussion.
The following form of gene therapy has been described as treatment for malignant brain tumors.
Patients undergo surgery to remove as much of the tumor as possible. After surgery, the patients are infused with a virus that has been genetically altered so that it is not infectious and so that it contains a gene from the herpes simplex virus. The herpes gene is sensitive to a drug called ganciclovir. Once inside the brain, the genetically altered virus infects any remaining tumor cells. When this occurs, the herpes gene is established inside the cancer cells. After the virus infects the cancer cells, the patients are given ganciclovir. This drug would kill both the virus and the brain tumor cells.
Code the Other Cancer-Directed Therapy field to 2 [Other experimental cancer-directed therapy (not included elsewhere)].
Radiation: Is "consolidated" radiation therapy coded as part of first course therapy when there is no documentation of "planned treatment" and the radiation is done 4 months after the initiation of treatment?
Yes, "consolidation" treatment is part of a planned treatment regimen. A treatment regimen may consist of the four following phases:
Surgery of Primary Site--Skin: Explain the difference between code 30 and code 45.
Code 30 [Biopsy of primary tumor followed by a gross excision of the lesion]
Code 45 [Wide excision or re-excision of lesion or minor (local) amputation with margins more than 1 cm, NOS. Margins MUST be microscopically negative.]
For cases diagnosed 1/1/2003 and after: Code 30 represents a biopsy or excision in which the margins of excision are less than 1 cm or the margins are unknown. Code 45 represents a wide excision in which it is known that the margins of excision are greater than 1 cm.
Surgery of Primary Site--Cervix: How is this field coded for a cervix primary when a biopsy removes the entire tumor? See discussion.
Path from biopsy shows "severe dysplasia--CIN III" and the report from an endocervical curettage (ECC) is "chronic cervicitis"?
For cases diagnosed 1998 and later: Code the Surgery of Primary Site field to 25 [Dilatation and curettage; endocervical curettage (for in situ only)].
Surgery of Primary Site: Should laparoscopy be coded as exploratory surgery? See discussion.
Many surgeons are doing exploratory surgery with laparoscopy involving a very small incision, but they can examine organs and take biopsies. Should laparoscopy be coded as exploratory surgery?
For cases diagnosed 1/1/1998 and later: Exploratory surgical procedures, such as laparoscopic surgeries, are not coded in the Surgery of Primary Site field.
Multiple Primaries (Pre-2007): Is an in situ tumor followed by another in situ tumor in the same location a new primary? See discussion.
Example: Six months after an in situ lesion was excised from the buccal mucosa, another in situ lesion was excised from the same area of the buccal mucosa with no mention of it being recurrent.
For tumors diagnosed prior to 2007:
Code as a second primary if the second in situ tumor occurred more than 2 months after the first, and it is not referred to as recurrent by the clinician or pathologist. There are no special rules for determining the number of primaries when an in situ lesion follows an in situ.
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.
