Conditions
Brief summary
This study aims to investigate immune changes which occur before and following standard radiotherapy in a range of tumour types. We will collect tissue and blood samples before and after radiation treatment from participants across six cancer types: cervical, rectal, Head and Neck cancer, nodal non-Hodgkin lymphoma, cutaneous lymphoma and cutaneous squamous cell carcinoma/ basal cell carcinoma.
Detailed description
The purpose of this prospective, non-CTIMP, translational study is to assess the feasibility of achieving paired biopsies for immune analysis in patients across six different cancer types: cervical, rectal, Head and Neck cancer, nodal non-Hodgkin lymphoma, cutaneous lymphoma and cutaneous squamous cell carcinoma/ basal cell carcinoma. All participants will have a minimum of 1 mandatory biopsy (during/post-radiotherapy \[irradiated site\]) and the potential to have a pre-treatment biopsy if the archival biopsy does not meet the suitability criteria. Matched blood samples will be collected from participants at baseline, during/post-radiotherapy, and if radiotherapy continues after the on-treatment biopsy is taken, an additional end of treatment blood sample will be collected. We aim to recruit 10-20 participants per study arm, with the option to increase numbers in study arms that are recruiting well - a maximum of 120 patients in total will be recruited to the study.
Interventions
A pre-treatment diagnostic biopsy sample plus 1 mandatory biopsy (during/post-radiotherapy \[irradiated site\]) will be collected from each participant. Matched blood samples will be collected from participants at baseline, during/post-radiotherapy, and if radiotherapy continues after the on-treatment biopsy is taken, an additional end of treatment blood sample will be collected.

Eligibility
Inclusion criteria
* Histologically confirmed cancer, Stage I-IV, in one of the following: Cervical, rectal, nodal Non-Hodgkin lymphoma, cutaneous lymphoma, Head & neck cancer * Diagnostic/pre-treatment biopsy confirmed suitable for translational research \* * Performance status - ECOG 0-2 (Refer to appendix 1), ECOG 3 allowed for arm F (unrelated to underlying cancer) as this group of patients often have ECOG 3 due to age and comorbidities. * Age ≥ 18; no upper age limit. * Participant considered suitable for radiotherapy * Before participant registration, written informed consent must be given according to GCP and national regulations. \*Pre-treatment biopsy must be from the gross tumour volume within the planned radiation field and must also: * Have been formalin fixed for \>12h and \<72h * Have tumour tissue and morphology confirmed by H&E staining * Contain sufficient tumour cells (approximately 100)
Exclusion criteria
* Participants deemed unsuitable for a biopsy (during or following radiotherapy) in the opinion of the treating oncologist. * Participants who have received chemotherapy within 28 days of starting radiotherapy. * Participants with intercurrent or past history of hepatitis B, C or human immunodeficiency virus infection if known. A negative test result for hepatitis B, C and HIV infection is required prior to inclusion in the study.
Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Feasibility of obtaining paired biopsy samples | Within 6-7 weeks of starting radiotherapy | To assess the feasibility of obtaining tumour samples pre-radiotherapy (diagnostic or fresh) and a second biopsy during or immediately after radiotherapy, or a surgical sample, from patients undergoing standard of care RT. |
| Collection of matched blood samples | Within 6-7 weeks of starting radiotherapy | To obtain additional matched blood samples pre-radiotherapy, during or post-radiotherapy, and at the end of radiotherapy for assessment of immune status of peripheral blood in comparison to the intratumoural microenvironment. |
Other
| Measure | Time frame | Description |
|---|---|---|
| Immunohistochemistry analysis of expression markers on tumour tissue | Within 6-7 weeks of starting radiotherapy | Immunohistochemistry (IHC) analysis of expression markers on tumours pre-radiotherapy and during/post radiotherapy |
| RNA evaluation of immune signatures | Within 6-7 weeks of starting radiotherapy | RNA evaluation of immune signatures in tumour tissue and blood pre-radiotherapy and during/post radiotherapy |
| Analysis of peripheral blood mononuclear cells | Within 6-7 weeks of starting radiotherapy | Assessment of changes in immune phenotypic markers |
| Analysis of plasma proteins, cytokines and chemokines | Within 6-7 weeks of starting radiotherapy | Analysis of plasma proteins, cytokines and chemokines as biomarkers of immune response |
