Efficacy of radiotherapy in treating local recurrence concomitant with distant metastasis of nasopharyngeal carcinoma: a long-term retrospective multicenter study.

Purpose: Patients with nasopharyngeal carcinoma (NPC) experiencing locoregional recurrence concomitant with distant metastases (rmNPC) after initial treatment represent a unique subgroup with significant management challenges. This study aimed to evaluate overall survival (OS) in rmNPC patients treated with systemic therapies with or without radiotherapy.

Methods: This retrospective multicenter study included patients with locally recurrent and metastatic NPC from five hospitals.

Phosphorus-solubilizing fungi promote the growth of P. Y. Li by regulating physiological and biochemical reactions and protecting enzyme system-related gene expression.

Introduction: P. Y. Li is a plant used to treat respiratory diseases such as pneumonia, bronchitis, and influenza.

Bone-Induced Her2 Promotes Secondary Metastasis in HR+/Her2- Breast Cancer.

Bone metastases can disseminate to secondary sites and promote breast cancer progression creating additional clinical challenges. The mechanisms contributing to secondary metastasis are barely understood. Here, we evaluate the prediction power of Her2-expressing (Her2E) circulating tumor cells (CTCs) after analyzing over 13,000 CTCs from a cohort of 137 metastatic breast cancer (MBC) patients with initial HR+/Her2- status and employ preclinical models of bone metastasis (BM) to validate the role of Her2E CTCs in multi-organ metastases.
