简要总结
The objective of this study is to evaluate the efficacy of stereotactic body radiation therapy (SBRT) as additional treatment after standard chemotherapy regarding tumor local control, toxicity, progression-free survival (PFS), overall survival and quality of life. In addition, the objective is to explore the value of immunodynamics in peripheral blood for predicting PFS in patients undergoing chemotherapy.
详细描述
Rationale:
For patients with perihilar cholangiocarcinoma, surgery is the only treatment modality that can result in cure. Unfortunately, in the majority of these patients the tumors are found to be unresectable at presentation due to local invasive tumor growth or the presence of distal metastases. For patients with unresectable cholangiocarcinoma, palliative chemotherapy is the standard treatment, yielding an estimated median overall survival of 12-15.2 months.
There is no evidence from randomized trials that support the routine use of stereotactic body radiation therapy (SBRT) for cholangiocarcinoma. The STRONG phase I feasibility study showed favorable outcomes regarding safety, and the therapy was generally well tolerated. Based upon these observations, a phase II multi-center study with SBRT after chemotherapy in patients with unresectable perihilar cholangiocarcinoma is proposed, in order to further research the efficacy of adding SBRT to standard chemotherapy.
In addition, an explorative translational research component is part of the study, in which peripheral immunodynamics, specifically myeloid nuclear factor kappa-light-chain enhancer of activated B cells (NF-kB) signaling and interferon-stimulated genes (ISG) responses within the myeloid cells, may help to predict survival after chemotherapy and may also help to predict the value of additional treatment with radiotherapy.

结局指标
主要结局
Local tumor control
时间窗: 42 months (maximum follow-up time)
Local tumor control is defined as time from inclusion to local radiological progression. Definition of progression is based on response evaluation criteria in solid tumors (RECIST) 1.1. In RECIST 1.1, response of a tumor to treatment is defined as either complete response (CR), partial response (PR), stable disease (SD), or progressive disease (PD).
次要结局
- Progression-free survival (PFS)(42 months (maximum follow-up time))
- Overall survival (OS)(42 months (maximum follow-up time))
- Adverse events(42 months (maximum follow-up time))
- Biliary stent-related events (SRE)(42 months (maximum follow-up time))
- Quality of life (QoL) - EQ-5D-5L(36 months)
- Quality of life (QoL) - QLQ-C30(36 months)
- Quality of life (QoL) - QLQ-BIL21(36 months)
