Abstract:
Objective To evaluate the correlation of prognostic nutritional index(PNI) with overall survival of postoperative patients with thymoma. Methods The clinical and pathological data of 173 postoperative patients with thymoma were analyzed retrospectively. Results R0 resection (P < 0.001), myasthenia gravis (P < 0.001), Masaoka stage (Ⅱ/Ⅰ: P=0.012; Ⅲ & Ⅳ/Ⅰ: P=0.011), WHO type (P < 0.001) and PNI (P=0.016) were independent risk factors for OS of postoperative patients with thymoma. R0 resection (P=0.001) and myasthenia gravis (P=0.039) were independent risk factors for OS of higher PNI group (PNI > 45); and Masaoka stage (Ⅱ/Ⅰ: P=0.012; Ⅲ & Ⅳ/Ⅰ: P=0.048), WHO type (P=0.039), R0 resection (P < 0.001) and myasthenia gravis(P < 0.001) were independent risk factors for OS of lower PNI group (PNI≤45). Patients with myasthenia gravis are prone to have a decreased PNI. Conclusion Complete resection, myasthenia gravis, Masaoka stage, WHO type and PNI are independent prognostic factors for postoperative patients with thymoma. Thymoma patients with myasthenia gravis have lower PNI and OS. PNI should be routinely monitored in thymoma patients with myasthenia gravis.
