Study Summary

This is a pilot study to test a hypothesis that a greater increase in serum chromogranin A (CgA) after a definitive radiotherapy (RT) with or without androgen deprivation therapy (ADT) is associated with a higher risk of prostate cancer recurrence after RT. Serum CgA level is measured before the start of RT and/or the start of neoadjuvant ADT for patients undergoing a definitive RT with or without ADT. CgA is also measured at various pre-defined post-RT time points. The study will analyze the followings: 1. Change in CgA level at various pre-defined post-RT time points from the baseline, 2. Correlation between the extent of post-therapy CgA change and Gleason score of malignancy, 3. Correlation between the extent of post-therapy CgA change and treatment outcome.

Primary Outcome

Post-RT CgA will be correlated with Gleason score (GS).The Gleason score is calculated by adding together the two grades of cancer cells that make up the largest areas of the biopsied tissue sample. The Gleason score usually ranges from 6 to 10. The lower the Gleason score, the more the cancer cells look like normal cells and are likely to grow and spread slowly.
