Researchers identified a genetic marker, microRNA, that differs in expression between African American and Caucasian women with breast cancer. The study found that African American patients overexpressed only six microRNAs, while Caucasian patients expressed 20 microRNAs, suggesting potential connections to treatment outcomes.
Two experimental drugs targeting the PD-1/PD-L1 pathway showed promising early results in patients with advanced non-small cell lung, melanoma, and kidney cancers. Significant tumor shrinkage was seen in patients treated with these therapies.
A new medication, abiraterone acetate, has been shown to slow the spread of metastatic prostate cancer while maintaining quality of life in patients. The study involved 1,088 men and demonstrated improved survival and reduced need for chemotherapy and pain medications.
Researchers have identified androgen receptors as a key target for treating breast cancer, leading to the development of enzalutamide as a potential new therapy. The study suggests that blocking these receptors can inhibit cancer growth, offering new hope for patients with hormone-dependent breast cancers.
