Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

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.

Participation Criteria

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
disease-free survival
Time Frame: five years
measure the disease-free survival rate for the two groups at five years
five years

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.
Outcome Measure
Measure Description
Time Frame
overall survival
Time Frame: five years
time from randomization to death as a result of any cause at five years
five years
safety: side effects of chemotherapy in the Treatment of Retinoblastoma
Time Frame: five years
Number of participants with side effects (systemic check-up, audio acuity, ect)before each treatment, at 1,3,6,9,12,18,24,30,36,42,48,54,60 months after the treatment.
five years
quality of life (PedsQL4.0 scale) in the Treatment of Retinoblastoma
Time Frame: five years
quality of life (PedsQL4.0 scale) before each treatment, at 1,3,6,9,12,18,24,30,36,42,48,54,60 months after the treatment. PedsQL 4.0 questionnaire has two modules (reported by parents and children) with 23 items encompassing the physical domains (8 items), emotional (5 items), social (5 items) and school (5 items). A five scores scale is used, after being asked, ''How much, in the last month, your child has had problems with'' (0 = never a problem; 1 = almost never a problem; 2 = sometimes a problem; 3 = is often a problem and 4 = almost always a problem). The items are reverse-score and linearly transformed to a scale from 0 to 100 (0=100, 1=75, 2=50, 3=25, 4 = 0). So high scores indicate better QoL.
five years
economic burden due to chemotherapy
Time Frame: during chemotherapy (9 weeks for 3-cycle group, and 18 weeks for 6-cycle group)
All costs, including direct cost and indirect cost, are expressed in Chinese YUAN. Direct costs include the average cost of systemic chemotherapy, operation, supportive treatment, and examination. Indirect costs include accommodation, transportation, diet, and lost income of parents.
