Molecular Pathogenesis and Targeted Therapy of Pancreatic Cancer

Area of Science:

• Oncology and Molecular Biology
• Cancer Genetics and Epigenetics

Background:

• Cancer development and progression involve accumulating genetic and epigenetic abnormalities.
• Cancer cell survival can be dependent on these molecular alterations, termed oncogene addiction.
• This dependency forms the basis for molecular targeted cancer therapy.

Purpose of the Study:

• To review the molecular pathogenesis of pancreatic cancer.
• To discuss driver mutations, including chromatin remodeling factors.
• To explore novel targeted therapy strategies based on cancer stemness and stromal niche concepts.

Main Methods:

• Review of recent scientific literature on pancreatic cancer molecular pathogenesis.
• Analysis of studies on driver mutations and their role in cancer.
• Examination of emerging concepts like cancer stemness and stromal niche.

Main Results:

• Pancreatic cancer, particularly pancreatic ductal adenocarcinoma, is a lethal malignancy.
• Targeted therapy for pancreatic cancer remains challenging compared to other types.
• Driver mutations, chromatin remodeling, cancer stemness, and stromal niche are key factors in pancreatic cancer.

Conclusions:

• Understanding molecular pathogenesis is crucial for advancing pancreatic cancer therapy.
• Targeted therapies need to address oncogene addiction, cancer stemness, and the stromal niche.
• Novel strategies are required to overcome challenges in treating pancreatic cancer.
