CLEVELAND — RECENT Research by Cleveland Clinic Differences have been shown in the tumor-associated bacteria associated with early-onset colorectal cancer, a finding that could lead to new screenings and treatments.
This study e-biomedicineused gene sequencing technology to compare tissue samples from 136 young-onset colorectal cancer patients with tissue samples from 140 patients with the same disease of average age. Researchers identified unique tumor-associated bacteria in the younger group and also found that they were more likely to have left-sided, rectal, and advanced-stage tumors, the Cleveland Clinic said.
“The unexplained increase in young-onset colorectal cancer is very concerning,” said Dr. Alok Khorana, a Cleveland Clinic oncologist and principal investigator of the study. “Our team found that bacteria are more abundant and compositionally distinct in tumors from younger-onset patients. These insights may lead to a better understanding of disease causes, new preventive approaches, diagnostic markers, and It helps us understand therapeutic targets.”
of American Cancer Society In the state, the incidence of young-onset colorectal cancer is increasing by 1.5% annually, and the mortality rate is also increasing by 1.2% annually. National Cancer Institute Journal Report If this trend continues, it is estimated that by 2030, the incidence of rectal cancer will quadruple and the incidence of colon cancer will double in this age group.
“Detailed characterization of this microbial signature of juvenile disease can open our eyes to new screening biomarkers and drugs that target the bacteria involved,” said the study’s authors, Cleveland Clinic Research Institute. said Dr. Simoli Barot.
Dr Nasir Sangwan, another author of the study, said further research was needed, including into lifestyle factors and how they contribute to disease and influence gut bacteria.
