Hereditary colorectal cancer tumors with high microsatellite instability (MSI) levels show a lack of genes responsible for DNA mismatch repair, vital to DNA replication. This can lead to faulty repair and colon cancer development.
A new study reveals that women have a higher proportion of gray matter to cranial volume than men, while men have more white matter and cerebrospinal fluid. This difference is associated with sex differences in cognitive performance, particularly in spatial tasks.
Researchers found that vaccinated patients had a significantly lower chance of death and relapse compared to non-vaccinated patients. The THERATOPEO vaccine increased specific killing activity against cancer cells, leading to longer remission periods.
A UCSF study reports that melanoma patients with cancer spread to their sentinel lymph nodes have a greater chance of experiencing disease recurrence and mortality. The study found that patients with negative SLN biopsies had lower rates of disease recurrence and mortality.
A retrospective statistical analysis of patients with advanced breast cancer found no survival benefit from high dose chemotherapy and bone marrow transplant. The study analyzed data from over 1,300 patients treated in the 1980s and early 1990s.
