Most pancreatic cancer patients are diagnosed at advanced stages, with poor survival rates and drug resistance making pancreatic cancer one of the highest causes of cancer death in the UK. Understanding the underlying mechanism behind its carcinogenesis, metastasis and drug resistance has become an essential task for researchers. We have discovered that a well-established tumour suppressor, EPLIN, has an oncogenic rather than suppressive role in pancreatic cancer.

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.

Background: The tumor immune microenvironment, including neutrophils and tertiary lymphoid structures (TLSs), is pivotal for HCC prognosis assessment. Tumor-associated neutrophils exhibit plasticity, adopting either an antitumorigenic N1 (MPO+ CD206-) or a pro-tumorigenic N2 (MPO+ CD206+) phenotype. We explored the prognostic value of neutrophil plasticity and TLS maturity in HCC in both tumor and peritumoral tissues and addressed their interaction.

The retroperitoneal liposarcoma (RLPS) is a rare malignancy whose only curative therapy is surgical resection. However, well-differentiated liposarcomas (WDLPSs), one of its most common types, can hardly be distinguished from normal fat during operation without an effective margin assessment method, jeopardizing the prognosis severely with a high recurrence risk. Here, we combined dual label-free nonlinear optical modalities, stimulated Raman scattering (SRS) microscopy and second harmonic generation (SHG) microscopy, to image two predominant tissue biomolecules, lipids and collagen fibers, in 35 RLPSs and 34 normal fat samples collected from 35 patients.
