Brief Summary
This study aims to investigate whether Sporoderm-removed Ganoderma lucidum spore powder (RGLS) ameliorates depression in thyroid cancer patients through gut-brain axis modulation, and to elucidate the underlying microbial and metabolic mechanisms. This 3-month randomized, double-blind, placebo-controlled trial will enroll 300 postoperative papillary thyroid carcinoma patients with depressive symptoms (HAMD-24 ≥ 8). Participants will be randomly assigned(2 : 1) to receive RGLS (4 g/day) or matched placebo.
