Objective: To investigate the efficacy and safety of local intra-arterial chemotherapy combined with immune checkpoint inhibitors in the treatment of unresectable head and neck squamous cell carcinoma (HNSCC).

Methods: A retrospective analysis was conducted on the clinical data of eight patients diagnosed with unresectable HNSCC at our hospital from January to December 2023. All patients were diagnosed by pathological diagnosis and treated with intra-arterial chemotherapy combined with immune checkpoint inhibitors. The overall response rate (ORR), progression-free survival (PFS), overall survival (OS), and adverse reactions were observed.

Results: The study cohort consisted of seven men and one woman, with a median age of 58.4 ± 13.1 years. Five patients were at stage IVA, one at stage IVB, and two at stage IVC. One patient was lost to follow-up, and among the 7 patients with complete data, the ORR was 85.7%. The median PFS and OS in the overall population were not achieved, and the patient tolerated the treatment well with no significant adverse effects.

Conclusion: Local intra-arterial chemotherapy combined with immune checkpoint inhibitors is an important future exploration direction for the treatment of unresectable HNSCC.

Background: Newly diagnosed glioblastoma (ndGBM) remains one of the most challenging malignancies to treat. Since the majority of patients experience tumor recurrence (rGBM) after first-line therapy, advancements in both initial and salvage treatments are essential.

Objective: We report our single-center experience on the feasibility and safety of superselective intra-arterial cerebral infusion (SIACI) with bevacizumab or cetuximab after osmotic blood-brain barrier disruption (oBBBd).

Background: Intra-arterial chemotherapy (IAC) is a growing method of therapy for retinoblastoma (Rb). There is an absence of data to support the safety of catheterization with intra-arterial infusion in this pediatric population OBJECTIVE: To focus on the non-ocular catheter/procedural-related complications that our practice has experienced in order to lay a foundation for practices interested in performing these procedures and hopefully, to help prevent them from occurring.

Methods: This is a retrospective review of the patient population with Rb treated in our center from May 2006 through May 2024.
