Location of rare cancer impacts survival, study suggests
A rare, aggressive cancer, commonly found in the uterus, limbs and abdomen, behaves differently depending on where it is found in the body, according to new research.
A recent study has revealed that the location of leiomyosarcoma, a rare and aggressive type of cancer affecting smooth muscle cells, significantly impacts a patient's survival odds, according to research conducted by scientists at the University of Edinburgh. Leiomyosarcomas located in the uterus, urinary tract, and trunk areas had the worst survival rates, compared to those found in the limbs, head and neck, and male reproductive tract.
The research, which studied 11,700 patients, suggests that tumor location could provide clinically meaningful information on disease risk beyond just the stage and grade of the cancer. The findings emphasize the importance of accounting for tumor location when analyzing new therapy studies, as clinical trials often do not consider this factor.
The study also identified biological differences between tumors in different locations, with uterine tumors more likely to have a specific genetic mutation compared to others. Experts highlight that these discoveries could aid in developing more personalized treatment approaches for leiomyosarcoma patients.
