Article Synopsis
  • FLASH ultra-high dose rate radiotherapy (RT) minimizes damage to normal tissues while effectively targeting tumors, resulting in a marked difference in treatment outcomes, commonly referred to as the FLASH effect.* -
  • Various hypotheses explain the FLASH effect, such as oxygen depletion and immune protection, and recent studies suggest combining FLASH RT with immune checkpoint inhibitors (ICIs) could enhance immune responses against tumors.* -
  • Despite its potential, the integration of FLASH RT with ICI therapy faces challenges like technical issues and lack of comprehensive data, indicating a need for further research in this area.*

Article Synopsis
  • The study looked at how the number of white blood cells (lymphocytes) in breast cancer patients might affect their chances of surviving after surgery and radiation treatment.
  • Researchers found that many patients had a drop in lymphocyte counts during treatment, but it was mostly not too severe.
  • Lower lymphocyte counts before treatment were linked to lower survival rates, suggesting that checking these counts could help doctors understand a patient's prognosis better.

This study aimed to predict the 5-year overall survival (OS) benefit of pola-R-CHP versus R-CHOP in the POLARIX trial based on the 2-year event-free survival (EFS) and progression-free survival (PFS) rates in diffuse large B-cell lymphoma (DLBCL). We identified randomized controlled trials (RCT) published before 31 May 2023. The correlation between the logarithmic (log) hazard ratio (HR) for EFS (HR) or PFS (HR) and the HR for OS (HR) was estimated at the trial-level.

Radiotherapy is an effective treatment for indolent non-Hodgkin lymphoma (iNHL); however, the optimal radiotherapy dose remains to be determined. We hypothesize that a suitable dose may exist between 4 and 24 Gy. This prospective multicenter phase II trial intends to recruit 73 sites of iNHL patients, who will receive involved-site radiotherapy of 12 Gy in four fractions.
