Genetic characteristics of a patient with multiple primary cancers: A case report

Figure 1 Postoperative histopathology of two lesions. A: Postoperative histopathology of esophageal squamous-cell carcinoma lesion (magnifications, × 400); B: Postoperative histopathology of gastrointestinal stromal tumour lesion (magnifications, × 400).

Figure 2 Preoperative computed tomography images. A: Computed tomography (CT) scans of the chest showed a tumour in the esophagus; B: CT image of nodules of the lesser curvature of the stomach. The orange circles indicate tumour lesions.

Figure 3 Genetic test results of three lesions. A: Venn diagram of mutant genes; B: Venn diagram of mutant gene loci; C: Patterns of common gene variants and signaling pathways; D: Copy number variation heat map. PYP161474 represents tissue specimen of colorectal adenocarcinoma, PYP20190282-10 represents tissue specimen of gastrointestinal stromal tumour, and PYP201902382-3 represents tissue specimen of esophageal cancer.
