FOLR1 and gastric cancer: A study by Gonzalez et al. explored the diagnostic potential of FOLR1 in gastric cancer using a liquid biopsy technique, emphasizing its overexpression and diagnostic relevance [20]. Our findings indicate a significant overexpression of FOLR1 and FOLR2 in gastric cancer tissues compared to normal gastric mucosa, aligning with previous studies that highlighted the aberrant expression of folate receptors in malignancies [16,21].
