【摘要】 目的 探討替吉奧膠囊聯合奧沙利鉑治療晚期胃癌的近期療效和毒性反應。 方法 2010年1-7月，16例晚期胃癌患者根據體表面積來確定初始劑量，體表面積lt;1.25 m2，替吉奧膠囊40 mg/次，2次/d；體表面積1.25~1.5 m2，替吉奧膠囊50 mg/次，2次/d；體表面積gt;1.5 m2，替吉奧膠囊60 mg/次，2次/d，早、晚飯后分別口服1次，連續服用28 d，停藥14 d。奧沙利鉑注射液130 mg/m2加入5%葡萄糖注射液500 mL避光緩慢靜gt;2 h，第1、21天重復，連用2周期。按RECIST 1.1標準評價客觀療效和不良反應。 結果 16例患者中PR 9例（56.3%），SD3例（18.8%），PD 4例（25%），總有效率為69.0%。不良反應主要是血液學毒性、胃腸道反應及外周神經毒性，且均在Ⅰ~Ⅱ。 結論 替吉奧膠囊聯合奧沙利鉑方案治療晚期胃癌的近期療效較好，不良反應可以耐受，值得進一步研究應用。【Abstract】 Objective To explore the early efficacy of Oxaliplatin combined with S1 capsule on advanced gastric cancer and observe the toxicity. Methods A total of 16 patients with advanced gastric cancer from January to July 2010 were treated with chemotherapy: oxaliplatin 130 mg/m2 mixed with 5% glucose injection 500 mL in the first day and repeated in the 21st day; Po after breakfast and dinner: S1 capsule with an initial dose according to the body surface area. Body surface lt;1.25 m2, 40 mg once, twice per day; body surface:1.25-1.5 m2,50 mg once, twice per day; body surface gt;1.5 m2, 60 mg once, twice per day. The medication lasted for 28 days, withdrew for 14 days. All of the patients underwent the treatment for two cycles. Efficacy and toxicities were evaluated according to the RECIST 1.1 standard. Results Of the 16 patients, partial remission (PR) was in nine (56.3%), stable disease was in three (18.8%) (SD), and progression disease was in four (PD). The total response rate was 69.0%. The major toxicities included leucopenia, nausea, vomiting and neurosensory abnormity. Conclusion Oxaliplatin combined with S1 capsule is effective on advanced gastric cancer, and the adverse effects are tolerable.
Objective
To observe the early efficacy and toxicity of gemcitabine plus tegafur, gimeracil and oteracil potassium (S-1) regimen (GS regimen) in patients with metastatic castration-resistant prostate cancer (mCRPC) after docetaxel failure.
Methods
From July 2013 to December 2015, sixteen mCRPC patients who failed in the treatment of docetaxel-based chemotherapy in West China Hospital of Sichuan University were collected. And the patients were treated with gemcitabine 1 000 mg/m2 intravenously on Day 1 and S-1 40–60 mg/m2 orally dividedly twice daily on Day 1–10, which repeated every two weeks. The main outcome measures were total prostate-specific antigen (T-PSA) decline rate and pain remission rate.
Results
Of the 13 evaluable patients, the T-PSA decline rate≥50% was observed in 4 patients (30.8%). Among the 11 patients with bone pain, remarkable pain relief was observed in 4 cases (36.4%). Myelosuppression, gastrointestinal reaction, rash and fatigue were the commonly observed adverse reactions and the toxicity of chemotherapy was tolerable.
Conclusion
The GS regimen is active and tolerable in patients with mCRPC after docetaxel failure.
