Objectives

Narrative objectives1

The aim of this study is to investigate the epidemiology of oligometastatic disease in advanced or recurrent thymic carcinoma to deepen our understanding of the disease, and to evaluate the clinical significance of local therapy in advanced and recurrent thymic carcinoma, thereby identifying the patient population that may benefit from local treatment.

Assessment

Primary outcomes

Epidemiological assessment
1) The prevalence of oligometastatic disease in patients with advanced or recurrent thymic carcinoma, as well as patterns of metastasis (metastatic organs and number of metastatic lesions)

2) The frequency and types of local therapy administered for oligometastatic disease

Prognostic evaluation
Overall survival (comparison between patients who received local therapy and those who did not)

Key secondary outcomes

Efficacy and safety of first line treatment
Progression free survival (PFS), objective response rate (ORR), disease control rate (DCR), and incidence of adverse events

In patients who underwent local therapy
Efficacy and safety of local therapy
PFS, ORR, DCR, and incidence of adverse events
Efficacy and safety of systemic therapy before and after local therapy
PFS, ORR, DCR, and incidence of adverse events
