Pancreatic cancer (PC), one of the most lethal diseases, remains a challenging problem. Novel cancer therapy targeting the immune system has been explored. Although immunotherapy has yielded a favorable response in pre-clinical models, no significant improvement has been confirmed in clinical trials for PC. This may be partly attributable to the unique immunosuppressive tumor microenvironment of PC. Studies focusing on combination therapy showed the ability to break the immunosuppressive tumor microenvironment and enhance the immune response, which can translate to clinical benefits. Moreover, the application of sequencing techniques and neo-antigen vaccines has achieved promising results in clinical trials, which promote the development of personalized immunotherapy. However, lack of effective biomarkers is another challenge for the realization of personalized immune medicine. Biomarkers are urgently needed to identify subgroup of patients who would benefit from immunotherapy. In this review, we discuss advances in immunotherapy for pancreatic cancer, as well as the challenges and prospects for personalized immune medicine.

Pretargeted Trop-2 immunoPET for rapid, selective detection of pancreatic tumors.

Memorial Sloan Kettering Cancer Center, New York, NY, United States.
Purpose: Recent clinical advances with the approval of antibody-drug conjugates targeting Trop-2 such as sacituzumab-govitecan and datopotomab-deruxtecan have garnered tremendous interest for their therapeutic efficacy in numerous tumor types including breast and lung cancers. ImmunoPET can stratify tumor avidity, clarifying patient eligibility for ADC therapy as well as a diagnostic companion during therapy. Slow antibody circulation requires days to reach optimal imaging timepoints.

Pancreatic ductal adenocarcinoma (PDAC) is characterized by a dense extracellular matrix (ECM) exhibiting high stiffness and fast stress relaxation. In this work, gelatin-based viscoelastic hydrogels were developed to mimic the compositions, stiffness, and fast stress relaxation of PDAC tissues. The hydrogels were cross-linked by gelatin-norbornene-boronic acid (GelNB-BA), thiolated macromers, and a 1,2-diol-containing linear synthetic polymer PHD.

In patients with synchronic liver colorectal metastasis, resection of the primary tumor and liver metastases is the only potentially curative strategy. In such cases, there is no consensus on whether resection of the primary tumor and metastases should be performed simultaneously or whether a staged approach should be performed (resection of the primary tumor and after, hepatectomy, or hepatectomy first). Patients with no bowel occlusion and with extensive liver disease are advised neoadjuvant oncological therapy.

Background: Pancreatic neuroendocrine tumors (PNETs) are uncommon and heterogeneous neoplasms, often exhibiting indolent biological behavior. Their incidence is rising, largely due to the widespread use of high-resolution imaging techniques, particularly influencing the diagnosis of sporadic non-functioning tumors, which account for up to 80% of cases. While surgical resection remains the only curative option, the impact of factors such as tumor grade, size, and type on prognosis and recurrence is still unclear.

Complete removal of metastatic disease and maintenance of an adequate liver remnant remains the only treatment option with curative intent concerning colorectal liver metastases. Surgery impacts on the long-term prognosis and complications adversely affect oncological results. The actual morbidity involving this scenario is debatable and estimated to be ranging from 15% to 50%.
