A 64-year-old man was admitted to the hospital due to "recurrent abdominal pain for 8 months" and had a history of multiple episodes of pancreatitis. CT scan showed an enlarged pancreas with no normal pancreatic tissue . Contrast enhancement scan in the arterial phase displayed moderate enhancement in the solid portion, while the cystic necrosis area showed no enhancement. It was suspected to be pancreatic cancer, and laparoscopic exploration of the pancreas followed by partial pancreatectomy was performed. Finally, it was confirmed as pancreatic squamous cell carcinoma by immunohistochemistry (P63 (+), CK5/6 (+)). Seven days after the operation, F18-FDG PET/CT showed multiple soft tissue density masses in the upper abdominal wall along the laparoscopic trajectory with increased uptake.

Introduction: Copy-number (CN) loss of chromosome 9p, or parts thereof, impair immune response and confer ICT resistance by direct elimination of immune-regulatory genes on this arm, notably IFNγ genes at 9p24.1, and type-I interferon (IFN-I) genes at 9p21.3.

Zinc is an essential trace element in the human body, playing a crucial role in cellular metabolism.Dysregulation of zinc homeostasis can lead to abnormal cellular metabolism, contributing to diseases and closely related to tumor development. Adequate zinc intake can maintain zinc homeostasis in the body and support normal cellular metabolism.

Nerves are often overlooked as key components of the tumor microenvironment. However, the molecular mechanisms underlying the reciprocal interactions between tumors and nerves remain largely unknown. In this study, we analyzed data from The Cancer Genome Atlas (TCGA) and identified a significant association between DKK1 expression and poor prognosis, as well as a correlation between DKK1 expression and myeloid-derived suppressor cell (MDSC) infiltration in head and neck squamous cell carcinoma (HNSCC) and pancreatic ductal adenocarcinoma (PDAC), two cancer types characterized by pronounced tumor-nerve interactions.

The PARP inhibitor olaparib is an anti-cancer agent based on synthetic lethality that targets poly (ADP-ribose) polymerases. It is used as a therapeutic agent for breast, ovarian, pancreatic, and prostate cancers carrying BRCA1/2 mutations that cause deficiency in homologous recombination. In recent years, acquired resistance to PARP inhibitors has become a clinical problem in PARP inhibitor-treated patients.

While metabolic reprogramming and remodeling of tumor microenvironment play important roles in the development of esophageal squamous cell carcinoma (ESCC), the mechanisms remain unclear. In this study, we found that pancreatic progenitor cell differentiation and proliferation factor (PPDPF) is upregulated in ESCC and its expression level is associated with lymph node metastasis. PPDPF was found to promote tumorigenesis, lymph node metastasis and distal metastasis of ESCC cells.
