Radiation Dose Study of Concurrent Chemoradiotherapy With Cisplatin Plus Fluorouracil in Oesophageal Cancer

July 18, 2012 updated by: Simcere Pharmaceutical Co., Ltd
The objective of this study is to determine the optimal radiation dosage used in concurrent chemo-radiotherapy in Chinese population. A dose climbing experiment is carried out with an initiate dose of 50Gy conventionally applied in Western countries.

Detailed Description

Esophageal cancer (EC) continues to be a major health burden worldwide. The 5-year survival rates for esophageal cancer have remained less than 15% over decades, probably because of ineffective therapies and the detection of late-stage cancers. Concurrent chemo-radiotherapy was established as one of the viable options for therapy of patients with localized EC following the results from the landmark trial of the Radiation Therapy Oncology Group (RTOG) 85-01 trial, showing a significant survival advantage of concurrent chemoradiation over radiation alone.

The use of radiochemotherapy with cisplatin and 5-fluorouracil (5-FU) is a well-accepted standard for the definitive treatment of esophageal cancer in China which has also been demonstrated efficacy and good tolerability internationally. The AJCC recommended dose range of radiotherapy for concurrent therapy is 45-50.4Gy. Moreover, (RTOG) 85-01 trial also established 50.4 Gy as the standard dose of radiation to be administered concurrently with chemotherapy. However, the appropriate dose of radiation fit for Chinese remains controversial. Due to insufficient evidence of EBM, radiation therapist in China always prescribe a radiation dosage by their own experience. Dosages (e.g. 60-64Gy) significantly higher than the international standard is commonly used in Chinese EC patients which lead to a greater likelihood of toxicity. Thus Chinese oncologists are urgent to reach a consensus about radiation dosage in the standard treatment of local advanced EC.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Objective Tumor Response
Time Frame: One day after completion of the initial therapeutic dose (50.0Gy) and the total dose of radiotherapy
objective evaluation is made according to the standards of Response Evaluation Criteria in Solid Tumors (RECIST)，defined as complete response(CR),partial response (PR)，stable disease(SD),and progressive disease (PD).Tumor sizes are measured using barium esophagram or CT.
One day after completion of the initial therapeutic dose (50.0Gy) and the total dose of radiotherapy

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
