Therapeutic Effects of Umbilical Cord Mesenchymal Stem Cells Transplantation on Systemic Lupus Erythematosus

【Abstract】 Objective To determine the efficacy of the third generation chemotherapy agents on relapsed post-surgery and advanced pulmonary sarcomatoid carcinoma (PSC). Methods We reviewed the medical records of 32 PSC patients. Their treatment modalities and survival rate, as well as risk factors associated with the survival rate including gender, age, location and size of tumor, relapse, initial diagnosis of stage, pathologic subtypes and smoking history were analysed. Results All of the 32 PSC patients received chemotherapy with gemcitabine combined with cisplatin (GP) or paclitaxel combined with cisplatin (TP). They had a median of 14 months overall survive (OS) and 5 months progress-free survive (PFS). The remission rate was 21.9%. An initial stage Ⅳ diagnosis and a larger than 6 cm tumor in diameter were independent factors associated with poor prognosis. Conclusion The efficacy of TP and GP chemotherapy on patients with relapsed post-surgery and advanced PSC is comparable with that reported by other researchers. An initial stage Ⅳ diagnosis and a larger than 6 cm tumor in diameter are predictors of poor prognosis.
