Spanish Surname or Origin: If Asians, Blacks and Whites with non-Spanish surnames are born in a Spanish country, is this field coded to Spanish or non-Spanish? See discussion.
For example, how do we code Miyako Mitsubishi with race listed as Japanese who was born in Peru or Sylvia Shapiro with race listed as White who was born in Argentina?
For both cases, code the Spanish Surname or Origin field to 0 [Non-Spanish/Non-Hispanic]. Persons with non-Spanish surnames would not be coded as being Spanish solely because they are born in a Spanish country. Do not code Spanish ethnicity based only on birthplace. Place of birth is a separate data item and it can be used in data analysis to identify this particular group of people.
EOD-Extension--Lung: Are "aortico-pulmonary window", "paratracheal space", and "subcarina" coded in the EOD extension field or in the EOD lymph node involvement field? See discussion.
Would a lung tumor that extends into the AP window be synonymous with extension into the mediastinum? If so, would this also apply to extension to subcarina, paratracheal space, and other such terms corresponding to areas listed in the mediastinal lymph node field under code 2?
For cases diagnosed between 1998-2003:
Extension into the aortico-pulmonary window, would be coded in the EOD-Extension field as 70 [mediastinal extension]. If the tumor extends into the paratracheal space, subcarina, or other areas listed under the code 2 in lymph nodes, code the EOD-Extension field to 70 to capture this type of involvement.
EOD-Pathologic Extension--Prostate: Does capsular invasion (code 32) take priority over apex extension (code 34) on prostate primaries? See discussion.
On prostatectomy, adenocarcinoma involves left apex and also left mid lobe where it focally invades capsule. Do we code extension to 34 - the highest numerical code, or to 32 to capture the capsular invasion? Do codes 33 and 34 represent a subset of code 31, and would code 32 represent greater tumor involvement?
For cases diagnosed 1998-2003:
Code the EOD-Pathologic Extension field to 32 [Invasion into (but not beyond)prostatic capsule] when there is both capsular and apex invasion of the prostate.
Although numerically lower, code 32 takes precedence over codes 33 [arising in the apex] and 34 [extending to the apex]. Codes 33 and 34 are "subsets" of code 31 [Into prostatic apex/arising in prostatic apex].
EOD-Size of Primary Tumor--Corpus Uteri: If both the width and depth of the tumor are provided, do we code the largest dimension in the tumor size field? If the width dimension is not provided, can we code the depth of the tumor in the tumor size field? See discussion.
Example: An endometrial primary is described as having, "a soft lobulated tumor diffusely involving the entire endometrium, extending 2.0 cm into the myometrium."
For cases diagnosed 1998-2003:
Code the EOD-Size of Primary Tumor field to 999 [unknown] for this case because this field is supposed to reflect the dimension for tumor width and not tumor depth. Tumor depth is coded in the EOD-Extension field.
EOD-Extension--Cervix: How do you code tumor extension described as "the in situ lesion extends from the cervix to the mucosa of the vagina"? See discussion.
Example: Cone biopsy of cervix and vaginal vault both show ca in situ. The op report stated: "lesion extending from the left lateral portion of the cervix onto the left lateral portion of the vagina." The pathologist stated it "appeared to be an in situ lesion extending from the cervix to the mucosa of the vagina."
For cases diagnosed 1998-2003:
Code the Primary Site to C53.9 [Cervix uteri] and the EOD-Extension filed to 00 [in situ]. In situ is a measurement of invasion. Extension of the cervical in situ carcinoma via the mucosa to the vagina does not affect the EOD extension code.
Reason no treatment/Surgery of Primary Site: Does the "Reason for No Cancer-Directed Therapy" field only relate to the "Surgery of Primary Site" field? If so, for what diagnosis years is that effective? Have SEER's coding guidelines changed over time? See discussion.
Whenever a surgical procedure is performed that results in a non 0 or 9 code in any one of the Surgery fields, should the Reason for No Site-Specific Surgery field be coded to 0 [Cancer-directed surgery performed]?
For cases diagnosed 2003 and forward: The field "Reason for No Surgery of Primary Site" applies only to surgery of primary site. This is a change from the pre-2003 instructions.
EOD-Lymph Nodes/EOD-Pathologic Review of Number of Regional Lymph Nodes Positive and Examined--Lung: How do you code these fields for clinically positive lymph nodes when the result of neoadjuvant treatment is that the lymph nodes are pathologically negative? See discussion.
The pt presents with "mediastinal adenopathy" for a lung primary and was treated with pre-operative radiation therapy. After two months, he was treated with surgery. The 10 lymph nodes removed were all negative. How does SEER code these three EOD fields?
Will an error be triggered in SEER Edits if you code lymph nodes as clinically positive in the EOD lymph node involvement field and yet pathologically negative in the number of regional nodes positive and number of regional nodes examined fields?
For cases diagnosed 1998-2003:
Code the EOD-Lymph Nodes field to 2 [Mediastinal, NOS]. Code the EOD-Regional Lymph Nodes Positive and Examined fields to 00/10. You will not have a problem with the SEER Edits. The EOD field is coded using clinical and pathologic information. All information gathered within four months of the date of diagnosis (in the absence of disease progression) or through completion of surgery(ies) can be used to code EOD. The clinically positive nodes justify the radiation therapy.
Multiple Primaries (Pre-2007)--Skin: If a patient presents with two separate lesions on the left cheek (i.e., left lateral cheek and left upper cheek) that both are histologically confirmed to be superficial spreading melanoma on the same day, is this coded as one or two primaries?
For tumors diagnosed prior to 2007:
Code as one primary.
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.
Multiple Primaries (Pre-2007)--Breast: Patient diagnosed with two lumps in same breast, different quadrants at same time. One was ductal carcinoma, cribriform type; the other was ductal carcinoma. How many primaries do we code? See discussion.
If the breast cancer had been diagnosed in 2000 we would have coded this case as one primary, code to higher ductal ca. For a 2001 or later diagnosis, should this be coded as two primaries?
For cases diagnosed 1998-2003:
Code this case as two primaries if the tumors are separate. Separate tumors have clear (negative) margins. If the tumors are not separate, code as one primary.
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.
