简要总结
This was a prospective phase II study on patients with locally advanced rectal cancer or local recurrence, to evaluate the pathological response and resectability of a neoadjuvant treatment based on the use of a combined treatment with VMAT-SIB and two drugs chemotherapy ( XELOX).
详细描述
This was a prospective phase II study on patients with LARC or local recurrence, to evaluate the pathological response and resectability of a neoadjuvant treatment based on the use of a combined treatment with VMAT-SIB and two drugs chemotherapy ( XELOX).
The primary aim was to asses the pathological response rate. Key secondary aim was the acute toxicity. Secondary aims were local control, disease-free survival (DFS) and overall survival (OS).
The follow-up period of each subjects started at the end of combined treatment and concluded after a period of maximum 60 months or until death.

研究组 & 干预措施
VMAT-SIB + XELOX
A VMAT-SIB technique was used. Radiation dose prescribed to PTV2 was 45 Gy (1.8 Gy/fraction), five sessions weekly in 25 daily fractions. A simultaneous boost was delivered on PTV1 with a total dose of 57.5 Gy (2.3 Gy/fraction). Dose-volume histograms (DVHs) were calculated for the PTV1, PTV2 and Organs at risks.
The prescribed concurrent chemotherapy consisted of oxaliplatin infusion 130 mg/m2 on days 1, 17, 35 and capecitabine 1650 mg/m2 daily (825 mg/m² twice daily, 5 days/week) over all the treatment.

结局指标
主要结局
Pathological response rate
时间窗: 6-8 weeks after chemoradiotherapy
Pathological response was determined according to the TNM classification system of the American Joint Committee on Cancer. The complete resection of the tumor (R) with no histological proven residual disease in the surgical specimen, was defined as pathological complete response (pCR =pT0). Near complete response (pTmic) was defined as the presence of a number of neoplastic cells inferior to 10%.
次要结局
- Acute Toxicity(During radiation treatment and at the first follow-up visit (4 weeks after RT).)
