Brief Summary

The objective of this single-center clinical study was to evaluate the disease control rate(DCR) and safety of multimodal radiotherapy in the treatment of patients with renal cell carcinoma (RCC) progressed after prior immunotherapy.

Outcome Measures

Primary Outcomes (2)

  • Disease control rate (DCR)

    After completing the full course of radiotherapy, the patients underwent periodic imaging evaluation. Tumor imaging evaluations within 48 weeks should be performed every 6 weeks (±7 days) and every 12 weeks (±7 days) after 48 weeks until disease progression, loss of follow-up, death, withdrawal of study informed consent, subject initiation of other antitumor therapy, or study termination. DCR was evaluated according to the Response Evaluation Criteria in Solid Tumors (RECIST v 1.1).

    Up to 1 year

  • Incidence of adverse events

    Adverse events according to Common Terminology Criteria for Adverse Events version 5.0 (CTCAE v5.0). The patients must be on the trial for at least 8 weeks. Adverse events must be attributable to radiation therapy or immunotherapy.

    Up to 1 year

Secondary Outcomes (5)

  • Progression-free survival (PFS)

    Up to 1 year

  • Objective response rate (ORR) (partial response or complete response)

    Up to 1 year

  • Overall survival (OS)

    Up to 1 year

  • Abscopal effects

    1 year

  • Change of lymphocyte subsets and tumor-associated macrophages (TAMs)

    1 year

Study Arms (1)

Experimental group

EXPERIMENTAL

For eligible subjects, multimodal radiotherapy will be added to the treatment besides original immunotherapy or combinations of immunotherapy and TKIs after adjustment.

Radiation: High-dose Radiotherapy (HDRT)Radiation: Low-dose Radiotherapy (LDRT)Drug: Anti-PD-1 monoclonal antibody

Interventions

SBRT was adopted, and radiotherapy plan was made according to the location and size of lesions (total dose 20-70Gy, 5-12Gy every time).

Also known as: Stereotactic Body Radiation Therapy, SBRT, Stereotactic Ablative Body Radiation Therapy, SABR
Experimental group

Radiotherapy plan was made according to the location and size of lesions (total dose 2Gy, 1Gy every time). After completing SBRT, LDRT was performed on as many metastatic sites as possible.

Experimental group

At the end of multimodal radiotherapy, immunotherapy was given within 7 days and in a subsequent LDRT. The maximum duration is 24 months.
