EOD-Size of Primary Tumor--Prostate: When there are multiple nodules in the prostate, can size of tumor be based on the size of the largest nodule? See discussion.
Rectal exam: Prostate enlarged, nodular and irregular. No masses. Pathology from prostatectomy: Focal nodules measuring up to 1.3 cm in diameter. Moderately differentiated adenocarcinoma. Would tumor size be 013 or 999?
For cases diagnosed 1998-2003:
Code the EOD-Size of Primary Tumor field to 013 [1.3 cm]. Code the size of a mass or nodule only when there is pathologic confirmation of malignancy. In the case you mention, the nodules were pathologically confirmed as cancer, so you would code the size of the largest nodule. If a nodule/or mass in the prostate is confirmed as cancer by needle biopsy, you would code the size of the mass or nodule.
Multiple Primaries (Pre-2007)--Breast: When a breast cancer is treated with less than a total mastectomy and more than 2 months later a tumor of the same histology is diagnosed in the same breast with no statement of "recurrence," is this a new primary?
For tumors diagnosed prior to 2007:
Count as 2 primaries when a subsequent malignant breast tumor is diagnosed more than 2 months later unless stated to be a recurrence. For cases diagnosed after 1/1/94, an in situ followed by an invasive breast cancer is counted as two primaries even if stated to be a recurrence.
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--Esophagus: What is the difference between C15.5 [Lower third of esophagus] and C15.2 [Abdominal esophagus]?
These descriptions represent the use of two different ways the esophagus can be divided anatomically. The two different systems used are illustrated in the SEER Self Instruction Manual for Tumor Registrars: Book 4. Assign the primary site code that describes the location of the tumor in the same way the tumor's location is described in the medical record.
Primary Site--Kaposi Sarcoma: Would the following Kaposi primaries be examples of cases not coded to skin for primary site? See discussion.
1. KS developed initially as a lesion in the oral cavity and followed by the appearance of skin lesions.
2. KS found in a resected parotid gland with metastasis to the parotid gland lymph node. No skin lesions identified.
3. KS discovered in a biopsied 3 cm axillary lymph node. Clinically, the patient had hepatosplenomegaly, ascites, and extensive mesenteric lymph nodes. (No mention of skin.)
Code the Primary Site field as follows:
1. C44.9 [Skin, NOS] as the default value when lesions develop simultaneously in skin and non-skin areas.
2. C07.9 [Parotid gland]
3. C44.9 [Skin, NOS] as the default value when there is no mention of lesions in the skin or other primary site.
Edward Klatt states in Practical AIDS Pathology, "...Visceral Kaposi (involving one or more internal organ sites) is also present in three-fourths of cases, but may not be diagnosed prior to autopsy. Visceral involvement frequently includes the lung, lymph nodes and gastro-intestinal tract."
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.
EOD-Size of Primary Tumor--Melanoma: How do you code tumor size for a melanoma diagnosed by a positive lymph node biopsy when the primary site is coded C44.9 because no primary site was identified? See discussion.
Should the size be 000 because no primary was found or 999 for unknown?
For cases diagnosed 1998-2003:
Code the EOD-Size of Primary Tumor field to 000 [No mass; no tumor found] when primary site is coded to C449.
Hematologic Transplant and Endocrine Procedures--Breast: Is a bone marrow transplant first course of cancer-directed therapy for breast cancer? If yes, are time guidelines relating to the first "remission" the same as for those used in leukemia primaries?
For cases diagnosed 1/1/2003 and after: A bone marrow transplant can be first course of therapy for cases in which there has been no progression of disease between the initial therapy (e.g., surgery, radiation, chemotherapy) and the bone marrow transplant. Code Hematologic Transplant and Endocrine Procedures field to 10-12 or 40 (depending on the type of bone marrow transplant performed).
Do not use leukemia treatment time guidelines when coding breast cancer treatment.
EOD-Size of Primary Tumor--Breast: If the patient has inflammatory carcinoma of the breast, is the tumor size coded as 998 even though we have a tumor size?
For cases diagnosed 1998-2003:
Code the EOD-Size of Primary tumor field to 998 [Diffuse; widespread; 3/4 or more of breast; inflammatory carcinoma] for all inflammatory breast carcinomas.
These cases have a worse prognosis because of the dermal lymphatic invasion. Half of the inflammatory breast carcinomas will have no palpable mass.
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.
EOD-Clinical Extension/EOD-Lymph Nodes--Prostate: How do you code clinical extension and lymph nodes for path only prostate cases treated with a TURP? Would clinical extension be coded to unknown or localized, NOS?
For cases diagnosed 1998-2003: Code the EOD-Clinical Extension field to 30 [localized, NOS] and the EOD-Lymph Nodes field to 0 [no lymph node involvement]. Per Note 7: Use code 30 when there is insufficient information as to whether the tumor is clinically apparent or inapparent but the tumor is confined to the prostate. This is an example of a case where there is insufficient information as to whether the tumor is clinically apparent or inapparent. Assume the tumor is confined to the prostate.
