A randomized trial shows that administering cancer immunotherapy before 3pm can nearly double survival time for patients with non-small cell lung cancer. Researchers found significant benefits from aligning treatment with circadian rhythms during the initial cycles. This marks the strongest evidence yet for chronotherapy in oncology.

Researchers in Brazil have uncovered how pancreatic cancer uses a protein called periostin to invade nerves and spread early. This discovery explains the disease's aggressiveness and suggests new treatment targets. The findings, published in Molecular and Cellular Endocrinology, highlight the tumor's ability to remodel surrounding tissue.

A new study reveals that chemotherapy's damage to the gut lining unexpectedly rewires the microbiota, producing a compound that strengthens immune defenses against cancer spread. This process reduces immunosuppressive cells and enhances resistance to metastasis, particularly in the liver. Patient data links higher levels of this compound to improved survival in colorectal cancer cases.

New research indicates that regular use of ibuprofen, a common painkiller, may reduce the risk of endometrial cancer by up to 25% in certain women. This finding comes from a large-scale study analyzing over 42,000 participants, highlighting the drug's anti-inflammatory properties. However, experts caution against using it for prevention due to potential side effects.

Scientists at Northwestern Medicine have developed an antibody that counters pancreatic cancer's sugar-based disguise, enabling the immune system to attack tumors more effectively. In mouse studies, the therapy slowed tumor growth by restoring immune activity. The team is preparing the antibody for human trials.
