Exploratory Study of Early Biomarkers Allowing Dynamic Assessment of Response to Treatment in Cancers of the Head and Neck (DART)

August 7, 2024 updated by: Royal Marsden NHS Foundation Trust
DART is an exploratory molecular analysis study to assess potential early biomarkers of treatment response in squamous cell carcinoma of the head and neck (HNSCC)

Detailed Description

If cancer that starts in the head or neck is not suitable for surgery or radiotherapy, then it cannot be cured. Unfortunately, people in this situation have a short life expectancy, with half dying within 12 months. There are treatments available that have helped people in this situation live longer, most recently drugs that stimulate the body's own immune system to attack the cancer, known as 'immunotherapy'. Some people do very well on these treatments, living many years, while the same treatments offer no benefit to others - it is not known why. This study is looking at collecting samples of a person's cancer, along with other body fluids, particularly blood and saliva, to see if the investigators can track changes in blood and saliva that happen in a person's cancer while they are receiving treatment. Additionally, samples of the cancer will be used to see if they can be grown in the laboratory to test growth behaviour and how well different treatments work.

The investigators will ask people being treated for incurable cancer that started in the head and neck for permission to collect their blood and saliva, along with samples of their cancer tissue, while they are having treatment. Nearly all patients will require a sample of their cancer tissue taken with a needle (a 'biopsy') anyway, and tissue samples can be taken as part of this process. Similarly, the safe administration of cancer drugs requires blood tests before every course of treatment, and research bloods can be taken from the same blood draw. A small number of people will be asked whether they give their permission for an extra biopsy of their cancer to allow further comparisons in the laboratory.

Cohorts and Interventions

Group / Cohort
Intervention / Treatment
Patients receiving systemic therapies for cancers of the head and neck
Patients undergoing systemic therapy for recurrent, metastatic, or locally advanced cancer of the head and neck not suitable for treatment with curative intent. A biological research study involving the collection of blood, tumour tissue, saliva, and other body fluids routinely examined during cancer care (e.g. cerebrospinal fluid (CSF), ascites, urine, stool or pleural fluids).
Circulating tumour DNA (ctDNA) can be identified in patients with a wide variety of cancers and has been shown to allow early prediction of disease relapse after treatment with curative intent in HNSCC.
