September 2024—Research has shown assessment of tumor-associated stroma to be of reliable prognostic value. The authors conducted a study in which they evaluated the prognostic value of tumor-stroma ratio in a large multicenter cohort of nasopharyngeal carcinoma. They used the conventional H&E-stained slides of 115 cases of nasopharyngeal carcinoma to assess tumor-stroma ratio as described in recent guidelines. The amount of tumor-associated stroma was assessed as a percentage and then tumors were classified as stroma high (more than 50 percent) or stroma low (50 percent or less). Kaplan-Meier curves, a χ2 test, and Cox regression univariable and multivariable analyses were conducted.
