75 YEARS LATER......

Androgen Deprivation therapy is still the standard of care in metastatic hormone

sensitive prostate cancer

Survival in Metastatic Prostate Cancer in Present Era

Mitoxantrone

Chemotherapy with mitoxantrone plus prednisone or

prednisone alone for symptomatic hormone-resistant

prostate cancer: a Canadian randomized trial with

palliative end points.

161 hormone-refractory patients

Primary end point was 2-point decrease in pain as assessed by a 6-point pain scale.

23 of 80 patients (29%) with Mito vs 10 of 81 patients (12%)

No overall survival difference.

J Clin Oncol 1996;14:1756-64.

• 242 patients with HRPC

• Randomized to receive either M+H or hydrocortisone alone.

• M+H:

– time to treatment failure

– disease progression

– QOL was better

• No difference in overall survival (12.3 months for M+H v 12.6 months for hydrocortisone alone

Summary

The value of docetaxel added to ADT for mHSPC is clearly established

– …but patient selection for appropriateness of chemotherapy is imperative.

Conclusions

• 1940 – 2003

• “Era of ADT”

• 2015-2016

• “Era of sequencing”

• 2004 – 2014

• “Era of Discovery”
