CS Extension--Cervix: How are "positive pelvic washings" coded for a cervical primary?
This answer was provided in the context of CSv1 coding guidelines. The response may not be used after your registry database has been converted to CSv2.
According to the CS Steering Committee, positive pelvic washings for primary cervical cancer are not part of the staging criteria in the collaborative staging system (nor in TNM and FIGO). Document positive pelvic washings in a text field. The CS steering committee will add a statement to CS extension to clarify this for cervix uteri.
Reportability/Recurrence (Pre-2007)--Bladder: If a patient has had recurrent invasive bladder cancers since 1971, should the latest recurrence in 2003 be SEER reportable because the case has yet to be reported to SEER?
For tumors diagnosed prior to 2007:
Because this 2003 recurrent bladder cancer was initially diagnosed prior to 1973, it is not reportable to SEER.
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--Ovary/Peritoneum: Should this field be coded to ovary or peritoneum when the bulk of the tumor is in the peritoneum and there is only surface involvement of the ovary?
If it is not clear where the tumor originated, use the following criteria to distinguish ovarian primaries from peritoneal primaries.
The primary site is probably ovarian, unless:
--Ovaries have been previously removed
--Ovaries are not involved (negative)
--Ovaries have no area of involvement greater than 5mm.
Descriptions such as "bulky mass," "omental caking" probably indicate an ovarian primary.
Descriptions such as "seeding," "studding," "salting" probably indicate a peritoneal primary.
Behavior Code--Breast: How is this field coded for a "non-invasive Paget disease of the breast?" See Discussion.
Historically, SEER collected Paget Disease of the breast with a behavior code of 3 [invasive]. There is no documentation to support this. The SEER EOD Manual only states that if the code is "05" [Pagets disease (without underlying tumor)], the behavior must be a 2 [in situ] or a 3 [invasive].
Code the behavior as /2 [in situ] for noninvasive Paget disease of breast. Noninvasive is a synonym of in situ.
If the pathology report documents that the Paget disease is in situ, the matrix principle in ICD-O allows you to change the behavior code to match the pathologist's statement.
CS Extension/Histology (Pre-2007)--Breast: Paget disease with underlying DCIS. How should CS Extension, SEER Summary Stage 2000, histology, and behavior be coded?
This answer was provided in the context of CSv1 coding guidelines. The response may not be used after your registry database has been converted to CSv2.
For tumors diagnosed prior to 2007:
Based only on the information provided above,
1. The CS extension code is 07 [Paget disease of nipple (without underlying invasive carcinoma pathologically)].
2. The SS 2000 stage is 1 [Localized].
3. The histology code is 8543 [Paget disease and intraductal carcinoma of breast]. The behavior code is 3 [Malignant].
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--Prostate: We are seeing numerous pathology reports with the following diagnosis: "Conventional (acinar) prostatic adenocarcinoma (M81403)." What is the correct histology code?
For cases diagnosed prior to January 1, 2007, assign histology code 8550/3 [Acinar adenocarcinoma].
Multiple Primaries (Pre-2007)/Date of Diagnosis--Bladder: How is date of diagnosis coded when metastases consistent with a bladder primary are found more than a year after a diagnosis of non-invasive bladder cancer? See Description.
A non-invasive papillary transitional cell carcinoma is removed by TURB in May 2002. In January 2003, a bone biopsy reveals metastatic transitional cell carcinoma consistent with bladder primary.
For tumors diagnosed prior to 2007:
Code a second bladder primary diagnosed in January 2003.
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 Therapy Initiated/First-Course of Cancer-Directed Therapy Fields/Summary Stage 2000--Prostate: How do you code these fields for a case that received preventative chemo before a definitive cancer diagnosis?
A patient has a "suspicious but not diagnostic" biopsy of the prostate in 09/2002. Doctor said it was not cancer and put the patient on a preventative chemo drug study (GTX-211). The patient returned for a repeat biopsy on 04/2003. Biopsy returned positive for adenocarcinoma. The patient had not been diagnosed when chemo was administered. Can the case be staged using the post-chemo information?
Stage this case the same as all other cases. Use only the information subsequent to the date of diagnosis to code stage and treatment.
The diagnosis date in the example is 04/2003. Do not use information prior to 04/2003 to code stage or treatment. Do not code the preventative chemo as treatment.
Reportability/Date of Diagnosis--Ovary: Is a patient SEER reportable in 2001 or 2003 if she presented with a diagnosis of papillary serous tumor of low malignant potential [borderline tumor] per the 5/2001 surgery but at the time of the planned second look laparoscopic surgery is stated to have Stage 3A ovarian cancer? See Discussion.
A patient was seen in 5/2001 for large pelvic mass growing from right ovary. After TAH and USO and partial omemtectomy, path diagnosis was papillary serous tumor of low malignant potential (borderline tumor), unruptured. Right ovary and omental implant have identical histologic appearance, except the psammoma body formation and the ovary does not.
Patient does not return for lap as planned in 6-12 months.
In 1/03 she returns to hospital with abdominal pain and has debulking, hemicolectomy and Hartmann's procedure. 1/03 Path report "metastatic papillary serous adenoca." Chart now says "History of stage 3A ovarian cancer."
Yes, this case is reportable in 2003. Malignancy was confirmed in 2003. The diagnosis made in 2001 is not reportable for that year, and was not reviewed or revised according to the information provided.
