[Pancreatic cancer microenvironment].

Pancreatic cancer remains one of the deadliest solid tumors in humans and an unsolved problem of today's medicine. Experimental studies reveal that the heterogeneous and complex pancreatic cancer microenvironment is responsible, not only for cancer growth, spread, development of metastases, but also for cancer recurrence and chemotherapy resistance. Chemotherapy affecting the cancer stroma is still under clinical and experimental research and remains hope for cure of pancreatic cancer. We present the cancer microenvironment characteristics and summary of experimental studies with use of agents affecting pancreatic cancer stroma.
