Although the overall incidence rate of colorectal cancer in the United States has been declining rapidly since the mid-1980s, the decrease has been in older adults. During this same period, incidence rates have been increasing sharply for adults younger than age 50, finds a study by the American...
Nearly 60% of colorectal cancer cases are diagnosed in patients ≥ 65 years, with a median age at diagnosis of 68 years,1 but this population makes up only 34% of clinical trial participants.2 In addition, the older adults enrolled on clinical trials are traditionally the most-fit older adults....
A large population-based study suggests that the utility of particular types of tumor-infiltrating lymphocytes (TILs) to predict colorectal cancer survival depends on where the tumor originates in the body. Although prior research has shown an association between high TIL density and longer...
