Tumore della prostata ormonorefrattario

• Circa l’80% dei paziente affetti da Ca della prostata metastatico che ricevono un blocco androgenico andrà in progressione entro 24 mesi

• Sopravvivenza mediana 12 mesi dalla progressione

• Sopravvivenza in relazione alla tipologia di presentazione:

18 mesi in caso di sola progressione biochimica

12 mesi in caso di progressione clinica asintomatica

6 mesi in caso di progressione clinica sintomatica

Due studi randomizzati dimostrano un vantaggio in QoL ed in “pain

relief “ utilizzando Mitoxantrone e Corticosteroidi vs solo

Corticosteroidi (non vantaggio in sopravvivenza)

FDA approva l’impiego del Mitoxantrone nei pazienti sintomatici affetti da HRPC

ma pochissimi pazienti vengono trattati

Due grandi studi di fase tre con Docetaxel dimostrano un vantaggio in sopravvivenza

per i pazienti trattati rispetto a quelli trattati con Mitoxantrone e Corticosteroidi

•The HRs for death similar in the TAX327 and SWOG 9916

• The secondary endpoints (PSA response, pain response, and QoL response)

• The docetaxel–prednisone regimen appeared to be better tolerated

Docetaxel plus prednisone is the appropriate

choice for the first-line treatment of HRPC

The regimen approved for use in HRPC in the U.S. and Europ

Tumore della prostata ormonorefrattario : quando trattare

Page 30: Improving the standard of care for patients with hormone resistant prostate cancer Teresa Gamucci Sora-Frosinone Highlights in the Management of Urogenital

Tumore della prostata ormonorefrattario : quando trattare

• TAX 327 ha incluso pazienti con e senza sintomi

• La probabilità di prolungare la sopravvivenza sembra uguale nei pazienti con alto o basso “disease burden”

• Ragionevole offrire il trattamento ai pazienti sintomatici e a quelli che svilupperanno sintomi nel prossimo futuro basandosi sulla clinica e sul “PSA doubling “

HRPC : Trattare tutti nello stesso modo ?

Il TAX327, ha dimostrato che la somministrazione settimanale di Docetaxel è attiva anche se non dimostra un

vantaggio significativo in sopravvivenza verso il Mitoxantrone

HR 0.87 median survivals 17.8 m

PSA 48 % (p 0.001)

QoL 23% (p 0.005)

Trattamento indicato per l’anziano frail

• Dal 2004 il trattamento chemioterapico standard dell’HRPC è il Docetaxel

• SWOG 9916 e TAX 327– Complessivamante 1600 pazienti trattati– SWOG 9916: Docetaxel + Estramustina vs

Mitoxantrone + Prednisone ↑ 2 mesi in OS– TAX 326: Docetaxel q21 + Prednisone vs

Mitoxantrone + Prednisone ↑ 2.5 mesi in OS
