Sternberg et al (abst. 5019): Satraplatin vs. Prednisone

• SPARC trial – Satraplatin, oral platinum compound

• Regimen: (patients failed prior chemotherapy)– Satraplatin 80 mg/m2/day x 5 q 5 weeks + Prednisone

– Placebo + Prednisone

• 950 patients, 9/2004 – 1/2006

• Satraplatin wins?– PSA response: 25% vs. 12%

– Pain response 24% vs. 14%

– Progression-free survival p< 0.00000003

– Time to pain progression

ASCO 2007

# 5503 RT +/- Chemotherapy Early-stage HR Endometrial Ca

• 382 pts

• Stage I,II,IIIA (peritoneal cytology only)

• External beam RT

• Chemo: Initially 4 courses cisplatin/doxorubicin; modified to permit carboplatin-based regimen

• Compliance: RT 93%; Chemo 75%

• Median follow-up 4.3 years

#5503

• Progression-free survival Hazard ratio 0.62 (p= 0.03) Absolute difference at 5-years: 7% (79% versus 72%)

• Cancer specific overall survival Absolute difference at 5-years: 5%

• in favor of combined modality regimen

• Investigators question: “Role of RT?”

# 5504 Adjuvant RT after Surgery High Risk Stage I Endometrial Ca

• RT vs observation until relapse

• Vaginal brachytherapy permitted in all patients (50% of women in trial)

• 906 pts; well-balanced prognostic factors

• 90% pts received protocol therapy

• Overall morbidity (including surgery): Observation arm: 26%; RT arm: 60%

#5504

• No difference in recurrence-free; disease-specific or overall survival (hazard ratio 1.01; p= 0.98)

• Vaginal brachytherapy (non-randomized analysis) reduced risk isolated vaginal recurrence HR 0.53; p=0.038

• Data raise question of role of routine adjuvant external beam radiation therapy in high-risk early stage endometrial cancer

#5505 “After 6 protocol”

• Observation vs single agent paclitaxel (175 mg/m2 every 3-weeks x 6 cycles)

• 200 pts

• Clinical complete response (48%)

• Pathological complete response (52%)

• No difference in progression-free or overall survival between study arms

# 5506 Gemcitabine versus LD 2nd-line Therapy Ovarian Cancer

• Gemcitabine (1000 mg/m2 over 30 minutes day 1, 8, 15 q-4 week schedule)

• Liposomal doxorubicin (40 mg/m2 q-4 weeks)

• Eligibility: Platinum-resistance and recurrence (up to 12 months)

• No difference in progression-free and overall survival
