Sleeping in on pancreatic cancer pain: Schwann cell secreted IL-6 pushes snooze on the pain alarm

Pain is an essential signal of danger and provides motivation to seek treatment, facilitating early diagnosis of disease. Pancreatic cancer is particularly lethal and has a 5-year survival rate below 5%. This is mainly due to delayed perception of visceral pain resulting in late diagnosis, by which time the tumour has metastasised.1 This sobering statistic highlights the need for rapid detection and the importance of understanding pain mechanisms in pancreatic cancer. Patients with pancreatic cancer who report more intense pain have shorter survival times, indicating pain intensity is prognostic for disease progression.2 Further, neuropathies including pancreatic nerve damage, neuritis and cancer cell invasion are typical features of pancreatic cancer, and the degree of neuropathy correlates with the severity of pain highlighting the importance of cancer–nerve interactions.2 3 This marked neural plasticity is supported by peripheral glial cells (Schwann cells) which have...
