High-dose radiotherapy for renal cell carcinoma treatment

Partial Volume High-Dose Irradiation in Renal Cell Carcinoma for Intra-TUmoural Control ALongside Current Management - a Randomised Feasibility Study

Not applicable Interventional Royal Marsden NHS Foundation Trust · NCT06995664

This study is testing whether a higher dose of radiation therapy can be a better option for people with kidney cancer compared to the standard treatment.

What this trial studies

This study is a prospective, randomized feasibility assessment comparing standard palliative dose radiotherapy to a high-dose hypofractionated radiotherapy regimen in patients with localized or metastatic renal cell carcinoma. The primary aim is to evaluate the feasibility of recruiting patients for this comparison, with a target enrollment of 24 participants divided equally between the two treatment arms. Participants will undergo a series of radiotherapy sessions and will be monitored for acute and late toxicity, as well as quality of life through validated questionnaires.

Who should consider this trial

Good fit: Ideal candidates include adults aged 18 and older with histologically confirmed renal cell carcinoma who are not suitable for surgical resection or other ablative therapies.

Not a fit: Patients with renal cell carcinoma who are candidates for surgical resection or have contraindications to radiotherapy may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide a more effective radiotherapy option for patients with renal cell carcinoma, potentially improving their treatment outcomes.

How similar studies have performed: While this approach is novel in the context of renal cell carcinoma, similar studies in other cancers have shown promising results with high-dose hypofractionated radiotherapy.

Eligibility criteria

Inclusion Criteria:

* Histologically confirmed renal cell carcinoma (RCC) (histological confirmation of metastasis not required) or clinically consistent with RCC as per multidisciplinary team (MDT) diagnosis.
* Not suitable for surgical resection, metastasectomy or ablative therapy due to tumour or patient factors
* All extracranial sites which clinically require radiotherapy (as per clinician discretion)
* Age ≥18 years
* Karnofsky Performance Status (KPS) ≥50
* Adequate baseline organ function applicable to site-of irradiation
* Haemaglobin ≥90g/dl
* Platelets ≥50
* Bilirubin \<3x ULN
* INR \<1.4 or correctable with vitamin K
* AST or ALT \<5x normal range
* Creatinine \<200umol/L (or established on dialysis). Note patients on dialysis are unable to have dynamic contrast enhanced MRI.

Exclusion Criteria:

* Previous radiotherapy, such that the delivery of further radiotherapy is not feasible
* Unable to have necessary radiotherapy planning, radiotherapy related investigations/fiducials (if required)
* Co-morbidities or any psychological, familial, sociological or geographical condition which may preclude ability to undergo/attend investigations, treatment or follow-up
* Other active primary cancer
* Pregnant or lactating
* Requiring ongoing treatment with a concomitant medication, which is contraindicated alongside radiotherapy (e.g. methotrexate)
