Introduction: Understanding the reliability of outcomes in randomized controlled trials (RCTs) is crucial, as standard metrics, such as P-value do not fully capture result fragility. This led to the adoption of specific indices: the fragility index (FI), which measures the strength of trial through significant results by calculating the minimum number of patient status changes from nonevent to event required to make the results statistically insignificant; reverse fragility index (RFI), used for insignificant results; and continuous fragility index (CFI), which acts similar to FI for significant continuous outcomes. The objective is to assess the robustness of orthopaedics RCTs using these indices across leading orthopaedic journals.

Immune checkpoints and ncRNAs: pioneering immunotherapy approaches for hematological malignancies.

Cancer Cell Int

December 2024

Cell Therapy and Hematopoietic Stem Cell Transplantation Research Center, Research Institute for Oncology, Hematology and Cell Therapy, Tehran University of Medical Sciences, Tehran, Iran.

Hematological malignancies are typically treated with chemotherapy and radiotherapy as the first-line conventional therapies. However, non-coding RNAs (ncRNAs) are a rapidly expanding field of study in cancer biology that influences the growth, differentiation, and proliferation of tumors by targeting immunological checkpoints. This study reviews the results of studies (from 2012 to 2024) that consider the immune checkpoints and ncRNAs in relation to hematological malignancies receiving immunotherapy.
