Large cell neuroendocrine carcinoma (LCNEC) is a highly malignant cancer originally found in lung in 1991. In extremely rare occasions, primary LCNEC is found in the mediastinum; approximately 40 of such cases have been reported. Due to the limited number of reported cases, a standardized treatment protocol has yet to be established. We report a case of a 66-year-old woman with primary mediastinal LCNEC who presented with superior vena cava syndrome. Emergent radiotherapy was performed, followed by systemic chemotherapy with cisplatin and etoposide, which resulted in a dramatic tumor reduction. This is the first report describing the achievement of a complete response after systemic chemotherapy in a patient with primary LCNEC.

Background: A precise observation is that the cervix's solid tumors possess hypoxic regions where the oxygen concentration drops below 1.5%. Hypoxia negatively impacts the host's immune system and significantly diminishes the effectiveness of several treatments, including radiotherapy and chemotherapy.

Generalized pustular psoriasis (GPP) is a rare human autoinflammatory disorder with life-threatening systemic effects. Keratinocyte-derived interleukin (IL)-36 signaling has been identified as a key mediator of immune response in the skin of affected individuals. Recognition of various mutations along the IL-36 axis and the downstream nuclear transcription factor κB (NF-κB) signaling have established GPP as genetically, immunologically, and histopathologically distinct and amenable to immunomodulation, which is epitomized by the recent success of IL-36 antagonism.

Objectives: This study aimed to quantitatively evaluate the efficacy and safety of first-line systemic therapies for treating advanced hepatocellular carcinoma (aHCC).
Methods: The study included clinical trials of first-line systemic therapies for aHCC since the approval of sorafenib in 2007. Hazard function models were used to describe changes in overall survival (OS) and progression-free survival (PFS) over time.

Limited drug accumulation and an immunosuppressive microenvironment are the major bottlenecks in the treatment of glioblastoma multiforme (GBM). Herein, we report a copper-coordination driven brain-targeting nanoassembly (TCe6@Cu/TP5 NPs) for site-specific delivery of therapeutic agents and efficient immunotherapy by activating the cGAS-STING pathway and downregulating the expression of PD-L1. To achieve this, the mitochondria-targeting triphenylphosphorus (TPP) was linked to photosensitizer Chlorin e6 (Ce6) to form TPP-Ce6 (TCe6), which was then self-assembled with copper ions and thymopentin (TP5) to obtain TCe6@Cu/TP5 NPs.
