NCT07371234
Over 60% of head and neck squamous cell carcinoma (HNSCC) patients are diagnosed at a locally advanced stage. While standard treatments involve surgery and chemoradiotherapy, prognosis remains poor, with 50-60% experiencing local recurrence within two years. Neoadjuvant therapy can potentially reduce tumor burden, preserve organs, and lower distant metastasis risk. Despite the KEYNOTE-689 trial showing that adjuvant two-cycle pembrolizumab increased major pathological response to 9.8% in stage III-IVB HNSCC, this result remains insufficient. More effective immunotherapy-based combinations are urgently needed to improve long-term survival after neoadjuvant treatment. Preclinical and clinical evidence indicates that low-dose radiotherapy can activate the tumor immune microenvironment and synergize with immunotherapy. Based on this rationale, the present clinical trial will evaluate a neoadjuvant regimen combining LDRT with two cycles of an anti-PD-1 inhibitor in patients with surgically resectable, locally advanced HNSCC.
NCT07383454
Study design: prospective, single arm. Objectives: survey lung cancer detection rate of low-dose computed tomography (LDCT) screening in individuals who had never smoked. Participants will undergo questionnaires, and collecting specimens including blood, urine, and medical informations including results of pulmonary function tests, and LDCT screening upon inclusion. The participants will be followed up according to current standards of clinical practice.
