Article Synopsis
  • Driver mutations in tyrosine kinases like ALK are important in non-small cell lung cancer but uncommon in large cell neuroendocrine carcinoma (LCNEC).
  • A 55-year-old woman with a history of breast cancer developed advanced LCNEC 10 years later, exhibiting multiple brain metastases and testing positive for the ALK fusion gene, leading to treatment with lorlatinib.
  • The patient showed a significant tumor reduction after 6 weeks of lorlatinib therapy, indicating that ALK-positive advanced LCNEC might respond well to this treatment, especially for brain metastases.

Up to half of hepatocellular carcinoma (HCC) cases are diagnosed at an advanced stage, for which effective treatment options are lacking, resulting in a poor prognosis. Over the past few years, the combination of immune checkpoint inhibitors and anti-angiogenic targeted therapy has proven highly efficacious in treating advanced HCC, significantly extending patients' survival and providing a potential for sequential curative surgery. After sequential curative hepatectomy or liver transplantation following conversion therapy, patients can receive long-term survival benefits.

Breast cancer (BC) is a prevalent malignant tumor that poses a significant health risk to women. The complexity of basic BC research and clinical treatment is influenced by multiple factors, including age, fertility, hormone metabolism, molecular subtypes, and tumor grading and staging. Traditional in vitro models often fall short of meeting modern research demands, whereas organoids-an emerging 3D primary culture technology-offer a unique platform that better replicates the tumor microenvironment (TME).

Prostate cancer is a leading cause of cancer-related death in men worldwide. Luteinizing hormone-releasing hormone receptor (LHRH-R) agonists and antagonists are known to achieve castration-level testosterone suppression; however, long-term data comparing the survival benefits of these therapies are insufficient to inform treatment decisions. Furthermore, the advent of next-generation hormonal agents (NHAs), such as abiraterone and enzalutamide, have shifted the paradigm of managing prostate cancer.

Nanotherapeutics for Macrophage Network Modulation in Tumor Microenvironments: Targets and Tools.

Int J Nanomedicine

December 2024

Department of Biotherapy, State Key Laboratory of Biotherapy and Cancer Center, West China Hospital, Sichuan University, Chengdu, Sichuan, 610041, People's Republic of China.

Macrophage is an important component in the tumor immune microenvironment, which exerts significant influence on tumor development and metastasis. Due to their dual nature of promoting and suppressing inflammation, macrophages can serve as both targets for tumor immunotherapy and tools for treating malignancies. However, the abundant infiltration of tumor-associated macrophages dominated by an immunosuppressive phenotype maintains a pro-tumor microenvironment, and engineering macrophages using nanotechnology to manipulate the tumor immune microenvironment represent a feasible approach for cancer immunotherapy.
