Vulnerability and Risk of Neuropathic Pain in Cancer

This study is looking for two main groups of people: adults (over 18) who have cancer, and healthy volunteers. If you have cancer, you might be able to join if you are going through treatment for breast, gynaecological, bowel (colorectal), or lung cancer, and you're having treatments like chemotherapy, surgery, hormone therapy, or radiotherapy.

However, you wouldn't be able to join if you've had cancer or cancer treatment in the past, or if you have certain brain tumours or other serious neurological conditions like Parkinson's or Alzheimer's. You also can't take part if you are pregnant or breastfeeding, or if your doctor thinks there's another medical reason why it wouldn't be safe for you.

For healthy volunteers, you need to be over 18 and generally in good health with no history of cancer. You shouldn't be taking any medication, especially painkillers, in the week before joining, unless the study doctor says it's okay. Everyone taking part needs to be able to understand the study requirements and give their permission to join, and also be part of the French social security system, as the study is based there.

As this study is focused on assessments and doesn't involve new treatments, taking part would primarily involve attending appointments for detailed assessments. These assessments would focus on your thoughts and feelings about pain, as well as your general pain levels. The study is designed to gather information to understand vulnerability, so you wouldn't be given any new medications or specific treatments as part of the study itself. The exact number and duration of visits aren't specified but typically these involve a few appointments over a period to track changes.
