Brief summary
The investigational device is the Advanced Gynecological Applicator (AGA) Venezia configuration, an applicator to treat locally advanced stage cervical cancer. The goal of the study is to assess the performance and the unknown risks or complications of the AGA Venezia configuration during clinical use of the applicator.
Detailed description
This is a multi-center, prospective, post-market clinical follow-up study to assess the performance and the unknown risks or complications of the Advanced Gynecological Applicator (AGA) Venezia configuration during clinical use of the applicator. The AGA Venezia configuration is a CE-marked, FDA approved and commercially available product. The AGA Venezia configuration is a gynaecological applicator for intracavitary and interstitial brachytherapy. The radiation oncologist can use it for treatment of cancers in the vagina, cervix and uterus. Forty (40) participants will be included in this study at 5 sites: 3 centers in Europe and 2 centers in the United States.
Interventions
DEVICEAdvanced Gynecological Applicator configuration
The Advanced Gynecological Applicator Venezia configuration is a gynaecological applicator for intracavitary and interstitial brachytherapy. The applicator consists of tubes, caps and templates to place needles, which can be combined to reach a wide range of target areas. The tubes and possibly used needles, guide the radioactive source of the afterloader to the target volume. Dose optimization and dose fractionation is performed with the goal of adapting the dose to the target volume without exceeding the dose volume constraints for the surrounding normal tissues according to the standard cervical cancer treatment of the centre.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Performance of the AGA Venezia configuration applicator as assessed by the 'Applicator Performance Questionnaire' | Within one week after each individual insertion. No change is assessed. The procedure is performed per hospital standard. On average, the procedure and applicator insertions are performed twice. | Performance of the device is assessed via the 'Applicator Performance Questionnaire' completed by the radiation oncologist. Scale is as follows: Completely Agree/Agree/Neutral/Disagree/Completely Disagree/Not Applicable. The primary endpoint, the third question ('I am able to deliver conformal dose to the tumor target volume while effectively avoiding the organs at risk') on the Questionnaire will be summarized through descriptive statistics in general summary tables. Additionally, responses will be recoded numerically ('Completely agree' = 1, 'Agree' = 2, 'Neutral' = 3, 'Disagree' = 4, and 'Completely disagree' = 5). A five-number summary (min, first quartile, median, third quartile and max) and a boxplot will be shown. The question will also be recoded as success ('Completely agree'&'Agree') and failure ('Neutral', 'Disagree' & 'Completely disagree'). |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Risks and/or complications of the AGA Venezia configuration applicator as assessed by the 'Risks and Complications Questionnaire' | Immediately after each insertion and followed up during the first follow-up visit, typically three months after the last insertion. The procedure is performed per hospital standard. On average, the procedure and applicator insertions are performed twice. | Unknown risks or complications are assessed via the 'Risks and Complications Questionnaire' completed by the treating radiation oncologist. The treating radiation oncologist will be asked to complete this questionnaires to assess whether risks and complications occurred or not. There is no scale, but answer options include yes/no. The value NO is considered a better outcome. YES constitutes the worst outcome. Descriptive statistics presented in general summary tables will be provided, summarizing the number of non-missing observations (n), mean, standard deviation, minimum, median and maximum for quantitative data. For categorical data, frequency counts and percentages will be determined. |
