Medical Supporter — Мэдээллийн мэдэгдэл
Энэ нийтлэл нь олон улсын эмнэлгийн мэдээллийн эмхэтгэл бөгөөд эмнэлгийн зөвлөгөө биш; таны эмчийн оношлогоо, эмчилгээний төлөвлөгөөг орлохгүй. Энд буй мэдээлэл нь Японы томоохон эмнэлгийн байгууллагуудын нээлттэй эх сурвалжаас эмхэтгэсэн бөгөөд аливаа эмчилгээний тохиромж, үр дүн өвчтөн бүрээр өөр тул мэргэшсэн эмч тус бүрчлэн үнэлэх ёстой.
On May 4, 2023, Gerald W. Prager and colleagues published the results of the SUNLIGHT Phase 3 clinical trial in The New England Journal of Medicine. This study evaluated the efficacy and safety of combining Lonsurf (Trifluridine/Tipiracil) with Bevacizumab (Avastin) in patients with refractory metastatic colorectal cancer (mCRC).
Study Design: SUNLIGHT Trial
The international, randomized, open-label trial enrolled 492 patients with metastatic colorectal cancer who had received a maximum of two prior chemotherapy regimens for metastatic disease. Participants were randomized 1:1 into two groups:
- Lonsurf + Bevacizumab Group (N=246): Lonsurf (35 mg/m² twice daily on days 1–5 and 8–12 of a 28-day cycle) + Bevacizumab (5 mg/kg on days 1 and 15).
- Lonsurf Monotherapy Group (N=246): Lonsurf (35 mg/m² twice daily on days 1–5 and 8–12).
The primary endpoint was overall survival (OS).
Key Efficacy Results
The trial demonstrated a clear survival benefit for the combination therapy:
- Median Overall Survival (OS): 10.8 months for the combination group vs. 7.5 months for the Lonsurf monotherapy group (Hazard Ratio [HR] = 0.61).
- Median Progression-Free Survival (PFS): 5.6 months (Combination) vs. 2.4 months (Monotherapy) (HR = 0.44).
- One-Year OS Rate: 43% (Combination) vs. 30% (Monotherapy).
Safety Profile
The most common adverse events in both groups were hematological, including neutropenia, nausea, and anemia. No treatment-related deaths were reported in either group. The addition of Bevacizumab to Lonsurf was considered manageable and well-tolerated.
Conclusion
The SUNLIGHT trial results establish Lonsurf plus Bevacizumab as a new standard-of-care option for patients with refractory metastatic colorectal cancer, offering a significant survival advantage over Lonsurf monotherapy in the third-line setting.
