Prostate Oligometastatic Cancer Management Driven by Disease Biology et/or Immunoactivity (PROMETEO)

Summary

Currently, despite the advent of next-generation imaging has improved the detection of Oligometastatic prostate cancer (OMPC), prognostic biomarkers able to stratify patients and monitor treatment response are lacking and urgently needed. Mounting evidence suggests that molecular profiling of the disease and host immune activity evaluation can reveal OMPC heterogeneity and address the above unmet clinical need. This study aims at combining the analysis of several biomarkers to improve the prognostic stratification of OMPC patients
