EOD-Extension/EOD-Lymph Nodes--Testis: If the patient received chemo, should "bulky retroperitoneal adenopathy" be coded as involved lymph nodes in the EOD lymph node involvement field for a testicular primary treated with an orchiectomy that rendered a path diagnosis of "seminoma confined to the testicle"? See discussion.
Per an orchiectomy path diagnosis a seminoma was confined to the testicle. The only other workup, other than a scrotal ultrasound, was a staging CT scan that revealed bulky retroperitoneal adenopathy in abdomen and pelvis, as well as mediastinal adenopathy. There was also a peripheral pulmonary nodule. No final clinical diagnosis or stage was provided in the chart. Following the orchiectomy the patient was treated with chemo. Should we also have coded distant site lung involvement?
For cases diagnosed 1998-2003, code the EOD-Lymph Nodes field to 9 [unknown] because "adenopathy" is not used to code lymph node involvement. The physician varied from the usual treatment for a localized testicular carcinoma, which is an orchiectomy. The physician proceeded immediately to chemotherapy as further treatment. It is not clear whether the decision to treat with chemo was based on the nodes and/or lung being involved.
Search the record for the physician's opinion regarding distant metastasis. Do not code distant involvement based on a peripheral pulmonary nodule seen on CT without further proof. If no further information is available, code the EOD-Extension field to 99.
EOD-Size of Primary Tumor: Can you code the tumor size if you have the aggregate size given for two or more tumor masses?
For cases diagnosed 1998-2003:
No. Never code the aggregate size in the Size of Primary Tumor field when the pieces removed come from TWO OR MORE tumors. If there is a clinical statement regarding the size of two or more tumors, code this field to the size of the largest tumor.
The aggregate size can only be used to code the Size of Primary Tumor field when the PATHOLOGIST estimates the size of the tumor from the pieces of ONE tumor removed by the surgeon.
EOD-Extension--Urinary Tract: Can the rules used to code bladder extension involving the term "no involvement of muscularis/and no mention of subepithelium/submuscosa" be used to code extension for other urinary tract primaries, such as ureter?
For cases diagnosed 1998-2003:
No. The inferred descriptions of noninvasion apply to bladder cases only.
Histology (Pre-2007)--Bladder: What code is used to represent the histology "transitional cell and small cell carcinoma" of the bladder? See discussion.
Code 8045/3 is used for combination codes that represent a mixture of small cell carcinoma and any other carcinoma. When we use this histology code for bladder primaries with mixed transitional cell and small cell carcinoma, we encounter a problem with the SEER edits (site and morphology conflict).
For tumors diagnosed prior to 2007:
Please see SEER Inquiry question ID number 20041104.
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.
Histology (Pre-2007)/Diagnostic Confirmation: What code is used to represent the histology that initially presents on uterine curettage as a hydatidiform mole and after pulmonary metastases develop a month later, the clinical diagnosis is "metastatic gestational trophoblastic disease"?
For tumors diagnosed prior to 2007:
Code the Histology field to 9100/3 [Choriocarcinoma]. Gestational trophoblastic neoplasia includes the diagnosis of choriocarcinoma.
Code the Diagnostic Confirmation field to 8 [Clinical diagnosis only] based on the information above. However, if imaging, direct visualization, or another method identified the pulmonary metastases, then code the Diagnostic Confirmation accordingly.
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.
FIGO grade is something completely different from FIGO stage. FIGO stage is used to code EOD. FIGO grade is based on the percentage of non-squamous (i.e., solid) portions of the tumor and corresponds roughly to a three grade differentiation system: grade I, well differentiated (=<5% solid component); grade II, moderately differentiated (>5 - 50% solid); and grade III, poorly differentiated (> 50% solid). SEER is evaluating whether the ICD-O-3 6th digit differentiation codes (four grade categories) accurately represent the FIGO grade. For the time being, do not code FIGO grade.
For a diagnosis that includes commonly used differentiation term with a FIGO grade, such as "Moderately differentiated, FIGO grade II," disregard the FIGO grade and code the Grade, Differentiation field according to the term "Moderately differentiated."
Histology (Pre-2007): What code should be assigned to acinar adenocarcinoma and ductal adenocarcinoma?
For tumors diagnosed prior to 2007:
Assign code 8255 [Adenocarcinoma with mixed subtypes]. According to histology rule #4 for a single tumor on page 86 of the 2004 SEER manual, use a combination code if one exists.
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.
Histology: What code is used to represent the histology "endometrioid adenocarcinoma, villoglandular type"?
Assign code 8262/3 [Villous adenocarcinoma].
According to the WHO Classification of Tumours, Breast and Female Genital Organs (2003), villoglandular is one of four variants of endometroid adenocarcinoma. The corresponding ICD-O-3 code according to WHO is 8262/3.
EOD-Lymph Nodes--Testis: In coding lymph node involvement for a testicular primary, should we use code 5 (Size not stated) when there is not a pathologic size of the lymph node provided? See discussion.
Should Note 1 in the testis EOD be changed to "Metastases in lymph nodes are now measured by the size of the lymph node as stated in pathology report"? The SEER EOD-88, 3rd Edition, states that "when size of regional lymph nodes is required, code from the pathology report."
For cases diagnosed 1998-2003:
For testis cases only, "metastasis in lymph nodes" is measured by the size of the lymph node or the lymph node mass. It is acceptable to code the size of this metastasis from a CT scan or other imaging when a pathology specimen is not available for testicular primaries.
Surgical Procedure of Other Site--Pancreas: Should an embolization of liver metastasis for a pancreas primary be coded as treatment?
Code "embolization" (or hepatic artery embolization, HAE) to a metastatic site in Surgical procedure of Other Site. Assign code 1 [nonprimary surgical procedure performed].
This procedure was previously coded as other therapy, experimental. Code as surgery as of July 2005.
