EOD-Extension--Small Intestine: How do we interpret a pathology description of "extending through serosa and forming masses in the periserosal tissue" for a jejunum primary?
For cases diagnosed 1998-2003:
Code the EOD-Extension field to 55 [Invasion of/through serosa and adjacent connective tissue]. The description states the tumor extended through the serosa into periserosal tissue. The periserosal tissue in this case refers to adjacent connective tissue lying exterior to the intestinal wall and not the (sub)serosal tissue that lies exterior to the muscularis but inferior to the serosa. Analyze each case individually since pathologists are not consistent when using the above terminology.
EOD-Extension--Lung: If LUL mass "crosses the pleural surface" into the LLL, do we assume this represents extension to the pleura? See discussion.
9/22/93 Left upper lobe lobectomy: 3 x 3 cm mass in the periphery of the LUL near the LLL. Multiple enlarged nodes around the aortic arch and within the pulmonary fissure.
9/22/93 Pathology: Moderately differentiated Adenoca. The neoplasm does cross the pleural surface into the segment of the lower lobe. Lower margin of resection is free of neoplasm. Six lymph nodes negative for metastatic carcinoma. Tumor staged as T2N0M0 Stage Ib by physician.
Is tumor extension coded 10 [confined to one lung] or 40 [extension to pleura]?
For cases diagnosed 1998-2003:
Code the EOD-Extension field to 40 [extension to pleura]. The tumor has penetrated (extended to) the pleura.
EOD-Extension--Pancreas: How do you code extension when a mass is described on exploratory laparotomy as compressing the duodenum, arising in the head of the pancreas, "extending around" the superior mesenteric vein and artery, and "encasing" the portahepatis?
For cases diagnosed 1998-2003:
Code the EOD-Extension field to 40 [extension to peripancreatic tissue, NOS]. Neither of the terms "extending around" nor "encasing" are interpreted as involvement with tumor by SEER.
EOD-Extension--Cervix: Should this field be coded to 11 [minimal microscopic stromal invasion] or 12 [microinvasion] when there is only a statement of "microinvasion" but no measurements describing the level of involvement given?
For cases diagnosed 1998-2003:
Code the EOD-Extension field to 12 [microinvasion] when there are no depth of invasion measurements given.
Code the EOD-Extension field to 11 [minimal microscopic stromal invasion] when there is a statement of "minimal STROMAL invasion."
EOD-Extension--Corpus Uteri: What code is used to represent this field for a corpus primary (sounding 8 cm or less in length) treated with radiation prior to a hysterectomy that pathologically showed superficial myometrial invasion? Is it possible that the invasion could have been more extensive prior to the radiation treatment?
For cases diagnosed 1998-2003:
Code the EOD-Extension field to 12 [Myometrium, inner half] which represents the extension you know. In this particular case, there was no clinical evidence of extension outside the corpus. As long as the surgery was not performed because of disease progression, use information from the surgery to code EOD extension.
EOD-Extension--Hematopoietic, NOS: If a solitary plasmacytoma originates in the right tonsil and extends to the left tonsil, vallecula and hypopharynx, is extension still coded to 10 [localized disease, solitary plasmacytoma only]?
For cases diagnosed 1998-2003:
Code the EOD-Extension field to 10 [localized disease, solitary plasmacytoma only] for all cases of solitary plasmacytoma.
EOD Clinical Extension--Prostate: Can you assign code 15 if there is no TURP and no physical exam? See discussion.
[Code 15 = Tumor identified by needle biopsy, e.g. for elevated PSA, (T1c)]
Prostate case: Elevated PSA, Prostate u/s: no abnormal findings, Prostate biopsy: adenocarcinoma. Can this be clinically coded as 15? According to Prostate EOD Coding Guide (6/2001), code 15 requires documentation that the physical exam was negative, but in this case, we have no physical info.
For cases diagnosed 1998-2003:
Code the EOD Clinical Extension field to 30-34 when there is no documentation saying that the physical examination was negative.
EOD-Clinical Extension--Prostate: How is this field coded when biopsies of the prostatic apex are positive and the physician clinically stages the case as T1c?
For cases diagnosed 1998-2003:
Code clinical extension to 33 [arising in the prostatic apex] when a biopsy of the prostatic apex is positive for malignancy, with no further evidence of involvement. If biopsies of both the apex and another site within the prostate (for example right lobe) are positive and there is no mention that the malignancy arose in the apex, code extension to 34 [extending into the prostatic apex].
Tumor Markers--Breast: If the ERA/PRA results reported differ for separate breast specimens removed for a single primary, do we code the results as positive or negative?
For cases diagnosed 1998-2003:
Code both the Tumor Marker 1 and Tumor Marker 2 fields to 1 [positive] when a single primary breast tumor has both positive and negative ERA/PRA receptors.
EOD-Lymph Nodes--Lung: What code is used to represent this field when the only information is a description of:
1. "hilar mass"
2. "mediastinal mass"
3. "enlarged" or "greater than 1 cm" used to describe any of the lymph nodes listed under code 2 in the EOD Lymph Nodes field?
For cases diagnosed 1998-2003:
Code EOD-Lymph Nodes fields as follows for the examples given:
1) 9 [Unknown; not stated] for a "hilar mass"
2) 2 [Mediastinal] for a "mediastinal mass"
3) 2 [Mediastinal] for "enlarged" or "greater than 1 cm," if used to describe any of the named lymph nodes listed under code 2 in the EOD-Lymph Nodes field.
