Radiotherapy‐Associated Cellular Senescence and EMT Alterations Contribute to Distinct Disease Relapse Patterns in Locally Advanced Cervical Cancer

AbstractA notable number of locally advanced cervical carcinoma (LACC) patients experience local or distant disease relapse following radiotherapy. The contribution of tumor microenvironment (TME) to tumor recurrence at different sites remains unclear. Here, single‐nucleus RNA sequencing data from 28 pre‐ and on‐treatment LACC samples from patients with different disease relapse patterns is analyzed. The findings revealed opposing alterations in the expression levels of the cellular senescence pathway after radiotherapy in patients with local and distant relapses. In contrast, an increase in the expression of the epithelial‐mesenchymal transition module after radiotherapy in both relapse groups is observed. Cell–cell interactions, drug‐target expression analyses in malignant cells after radiation, and multiplex immunofluorescence of tumor tissue identified interleukin‐1 receptor type I (IL1R1) as a potential therapeutic target. It is demonstrated that combining the IL1R1 inhibitor anakinra with radiation can mitigate the effects of radiation on tumor cells. This study highlights the distinct roles of cellular senescence and EMT in tumor recurrence.
