SPI1 and sarcoma: Further analysis of a large variety of tumor types using TIMER2.0 revealed that the positive correlation between FOLR2 and SPI1 expression was highest in colon adenocarcinoma, HNSC and sarcoma (Figure 2I), and that the FOLR2–SPI1 correlation was more significant than the FOLR2–MAF correlation in almost every tumor type (Figure 2J).
