Study summary

This study is an exploratory study based on the previous study " A prospective, multicenter, randomized, parallel arm-controlled, superiority clinical study to evaluate the role of hydrogel spacer in reducing rectal radiation dose in cervical cancer radiation therapy", in which additional follow up study on the subjects of the previous study were conducted. Subjects (6 subjects in Phase I; 100 subjects in Phase II, 50 in the test group and 50 in the control group) who completed the pre-study will be enrolled in this study if they are willing to participate in the long-term follow-up by signing the informed consent form.

Read the detailed description

The purpose of this study is to evaluate the long-term benefit of hydrogel spacer when hydrogel is injected between the rectum and cervix in women undergoing radiation therapy.

Study arms

  • Experimental
    hydrogel spacer

    The Subjects randomized to the treatment group underwent placement of hydrogel spacer.

    Device: hydrogel spacer

  • No intervention
    Control

    The Subjects randomized to the control group did not receive injection of the hydrogel spacer.

Interventions

  • Devicehydrogel spacer

    Randomly assigned to either the treatment group, who were injected with hydrogel spacer, or the control group, who were not injected with hydrogel spacer.

What researchers measure

Primary outcomes

  1. The stability of the hydrogel spacer

    In order to verify the stability of the hydrogel spacer, this test will be based on MRI T2-weighed images.

    Time frame: Through study completion, an average of 12 months

  2. Scores from Quality of Life Questionnaire-Core 30 Rating (QLQ-C30)

    European Organization for Research on Treatment of Cancer (EORTC) QLQ-C30 is a comprehensive survey instrument designed to assesses the disease-specific aspects of cervical cancer and its therapies. The QLQ-C30 is composed of both multi-item scales and single-item measures. These include five functional scales, three symptom scales, a global health status / QoL scale, and six single items. All of the scales and single-item measures range in score from 0 to 100. A high scale score represents a higher response level. Thus a high score for a functional scale represents a high / healthy level of functioning, a high score for the global health status / QoL represents a high QoL, but a high score for a symptom scale / item represents a high level of symptomatology / problems.

    Time frame: through study completion, an average of 12 months

  3. Scores from Quality of Life Core Questionnaire Cervix Cancer Module 24 (QLQ-CX24)

    European Organization for Research on Treatment of Cancer (EORTC) QLQ-CX24 will be used to assess subjects' quality of life. EORTC QLQ-CX24 score from 0 to 100, higher scores indicate better quality of life or more symptoms.

    Time frame: through study completion, an average of 12 months

  4. Percentage of subjects with ≥2 grade chronic radiation rectal injury

    The percentage of subjects in the treatment and control groups who had ≥ grade 2 chronic radiation rectal injury after radiation therapy will be calculated and compared between the groups.

    Time frame: through study completion, an average of 12 months

  5. Adverse events requiring special attention

    The number of cases of adverse events requiring special attention related to radiation intestinal injury and the number of subjects having the above adverse events will be recorded in both the treatment and control groups.

    Time frame: through study completion, an average of 12 months

  6. The number of (serious) adverse events, (serious) device-related adverse events

    The frequency (number of events) of occurrence of (serious) adverse events and device-related (serious) adverse events will be recorded for the entire study period.

    Time frame: through study completion, an average of 12 months
