Clinical analysis of multiple primary gastrointestinal malignant tumors: A 10-year case review of a single-center

Figure 1 Tumor associations in patients with synchronous multiple primary malignant tumors and metachronous multiple primary malignant tumors. A: Number of patients with different tumor associations in the synchronous multiple primary malignant tumors; B: Number of patients with different tumor associations in the metachronous multiple primary malignant tumors. 1: Gastric cancer, 2: Colon cancer, 3: Rectum cancer, 4: Small bowel cancer.

Figure 2 Survival times of patients with multiple primary malignant tumors. A: Survival times of 85 patients with multiple primary malignant tumors (MPMTs) after diagnosis of the first primary cancer; B: Survival times of 85 patients with MPMTs after diagnosis of the second primary cancer; C: Survival times for the synchronous MPMT (SMPMT) and metachronous MPMT (MMPMT) groups after diagnosis of the first primary cancer; D: Survival times for the SMPMT and MMPMT groups after diagnosis of the second primary cancer. SMPMTs: Synchronous multiple primary malignant tumors; MMPMTs: Metachronous multiple primary malignant tumors.
