Rosai-Dorfman Disease
Conditions
Brief summary
In patients with Rosai-Dorfman disease (RDD), a treatment regimen of lenalidomide combined with dexamethasone is planned to be used.
Detailed description
Patients received oral lenalidomide 25mg on days 1-21 and dexamethasone 40mg on days 1, 8, 15, 22, in 28-day cycles for 12 total cycles.
Interventions
The combination therapy period consists of 12 cycles: Lenalidomide: 25mg, orally, D1-21, every 28 days per cycle. Combined with Dexamethasone: 40mg, orally, D1, 8, 15, 22, every 28 days per cycle. The single-agent maintenance period consists of 12 cycles: Lenalidomide: 25mg, orally, D1-21, every 28 days per cycle. The total treatment duration is 24 cycles or until disease progression, death, or the occurrence of intolerable toxicity.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Progression-free survival time (PFS) | From enrollment to the end of treatment at 8 weeks | PFS defined as the time from RD initiation to first documented disease progression, relapse after RD, death from any cause, or last follow-up. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Overall Response Rate (ORR) | From enrollment to the end of treatment at 8 weeks | The overall response rate (ORR) was defined as the cumulative proportion of patients attaining either a complete response (CR) or partial response (PR) . |
| Overall Survival (OS) | From enrollment to the end of treatment at 8 weeks | OS was measured from RD start to death or last follow-up |
| Adverse events | From enrollment to the end of treatment at 8 weeks | Toxicities were recorded and graded per National Cancer Institute Common Terminology Criteria for Adverse Events (NCI CTCAE) version 5.0. |
Other
| Measure | Time frame | Description |
|---|---|---|
| Correlation between next-generation sequence (NGS) and therapeutic efficacy/PFS | From enrollment to the end of treatment at 8 weeks | Correlation between the positivity of NGS in MAPK pathway and therapeutic efficacy/PFS |
| Fact-G | From enrollment to the end of treatment at 8 weeks | The score of Functional Assessment of Cancer Therapy - General |
