About

The goal of this clinical trial is to investigate the utility and effectiveness of a decision aid in cisplatin-intolerant patients with locally advanced cervical cancer.

The main questions it aims to answer are:

1. What is the effectiveness of the decision aid in reducing decisional conflict?
2. What is the utility of the decision aid in preparing for decision-making?

Participants will be asked to accomplish the Decisional Conflict Scale before and after using the decision aid.

Researchers will compare patients given routine care and the decision aid with patients given routine care to see if the decision aid reduces decisional conflict.

Full description

In locally advanced cervical cancer (LACC), adding chemotherapy (ChT) to radiotherapy (RT) improves survival at the cost of increased toxicity. Among patients with cisplatin contraindications, compliance to RT may be compromised. Shared decision-making (SDM) allows for more patient engagement in the decision-making process and decision implementation planning. In cancer-related decision-making, patient decision aids (PtDA) facilitate the SDM process and have increased patient knowledge and satisfaction and decreased decisional conflict and attitudinal barriers improved patient satisfaction and treatment compliance.

The CECIL study is a two-phase study to develop, validate and test the effectiveness of a PtDA for cisplatin-intolerant LACC patients faced with the decision of adding ChT to RT. Phase 1 is a mixed-methods study to develop a PtDA prototype and determine its content validity and user acceptability. Phase 2 is a block-randomized clinical trial to determine its effectiveness in reducing decisional conflict and its utility in preparing for decision-making. Adult women with biopsy-proven untreated LACC with cisplatin contraindications will be included in this trial.
