Brief Summary:
The purpose of this study is to compare effectiveness of short-term radiotherapy with neoadjuvant chemotherapy(Experimental group) with preoperative long-term chemoradiotherapy(Control group) in locally advanced rectal cancer. The hypothesis is 3-year disease-free survival in Experimental group was non-inferior to that in Control group.

Condition or disease Intervention/treatment Phase
Cancer, Rectum Radiation: Short-course radiotherapy with neoadjuvant chemotherapy Radiation: Long-term chemoradiotherapy Phase 3

Detailed Description:

The study is a prospective phase II/III randomized multicenter trial. The purpose of this study is to compare short-term radiotherapy with neoadjuvant chemotherapy(Experimental group) with preoperative long-term chemoradiotherapy(Control group) for middle-lower locally advanced rectal cancer. The primary endpoint is 3-year disease-free survival, and the secondary objectives are 3-year local recurrence-free survival, distant metastasis-free survival and overall survival. Furthermore, the late toxicity profile and quality of life (QoL) after 3 years follow-up are secondary endpoints. For each group, a plan for collection of serum/plasma/feces at different stages of treatment and for obtaining fresh tumor tissue for freezing prior to treatment was defined in the protocol.

The STELLAR-trial has been designed by National Cancer Center/Cancer Hospital, Chinese Academy of Medical Sciences, Peking Union Medical College, and the hypothesis is 3-year disease-free survival in Experimental group was non-inferior to that in Control group.

Arm Intervention/treatment
Experimental: Experimental group
The intervention of Experimental group is Short-course radiotherapy with neoadjuvant chemotherapy, which consists of a short-course radiotherapy (SCRT, 5 Gy x 5 alone), then after 7-10 days of radiotherapy completed, patients will receive neoadjuvant chemotherapy, given in 3 week cycle of capecitabine 1000 mg/m2 twice daily, day 1-14 combined with oxaliplatin 130 mg/m2 once. In total, 4 cycles of neoadjuvant chemotherapy are prescribed preoperatively, then followed by a total mesorectal excision(TME) and postoperative adjuvant chemotherapy. If patients are eligible for postoperative chemotherapy this should consist of at least 2 cycles, which are the same as neoadjuvant chemotherapy.
 Radiation: Short-course radiotherapy with neoadjuvant chemotherapy
Short-course radiotherapy with 4 cycles of neoadjuvant chemotherapy
Control group
The intervention of Control group is long-term chemoradiotherapy(CRT), which consists of a long-term chemoradiation (2 Gy x 25 with capecitabine) preoperatively, followed by a total mesorectal excision(TME) and then postoperative adjuvant chemotherapy. The radiotherapy is given in combination with capecitabine in a dose of 825 mg/m2 twice daily on days when radiotherapy, excluding weekends. If patients are eligible for postoperative chemotherapy this should consist of at least 6 cycles of capecitabine 1000 mg/m2 twice daily, day 1-14 combined with oxaliplatin 130 mg/m2 once every 3 weeks.
 Radiation: Long-term chemoradiotherapy
Standard chemoradiotherapy


Outcome Measures
Go to 
Top of Page Study Description Study Design Arms and Interventions Outcome Measures Eligibility Criteria Contacts and Locations More Information

Primary Outcome Measures :
  1. disease-free survival rate [ Time Frame: three year ]

Secondary Outcome Measures :
  1. overall survival rate [ Time Frame: three year ]
  2. incidence of surgical complications [ Time Frame: one month ]
    Surgical complications are defined as those occurring within 30 days after surgery, such as re-operation, anastomotic fistula, bleeding, infection and death related to the operation.

  3. incidence of acute toxicities during radiation or chemotherapy [ Time Frame: three months ]
    Number of participants with abnormal laboratory values and/or adverse events that are related to radiation or chemotherapy as assessed by Common Toxicity Criteria for Adverse Effects(CTCAE) v3.0.
