Core Tip

Core Tip: We report a case of multiple primary malignant neoplasms. In this case, next-generation whole exome sequencing confirmed that esophageal squamous-cell carcinoma and gastrointestinal stromal tumour were not genetically evolved from rectal adenocarcinoma that was removed 3 years ago but occurred independently. The results of next-generation whole exome sequencing of the tumour tissues confirmed the specimens’ evolution relationship.
