Question 20190030
Inquiry Details
References:
2018 Summary Stage. Male Genital System section-Prostate chapter, v1.1
Question:
Summary Stage 2018/Extension--Prostate: Can imaging be used to code SEER Summary Stage 2018? MRI shows tumor involved the seminal vesicles and the patient did not have surgery. AJCC does not use imaging to clinically TNM stage a prostate case.
Discussion:
Answer:
Note 5 was changed in Version 2.0.
Per Note 5 of the 2018 SEER Summary Stage Prostate chapter: Imaging is not used to determine the clinical extension. If a physician incorporates imaging findings into their evaluation (including the clinical T category), do not use this information.
This note was changed in Version 2.0 (2021 changes) to be in line with how AJCC stages; therefore, AJCC and Summary Stage agree.
History:
Answer Prior to Version 2.0
Per Note 5 of the 2018 SEER Summary Stage Prostate chapter: Imaging is not used to determine the clinical extension unless the physician clearly incorporates imaging findings into their evaluation. This note was added to be in line with how AJCC stages; therefore, AJCC and Summary Stage agree. Do not use the MRI findings when that is all you have and the physician does not document agreement with the MRI.
