導讀:肺癌患者的5年存活率與30年前相比有了很大提高,這與現代腫瘤醫學的發展和進步有密切的關系。先進儀器,使肺癌可以早檢查,早治療。與此同時,藥學水平也在不斷的提高,治療肺癌的多種分子靶向藥相繼問世。靶向治療相比傳統治療作用更準確,副作用更小,使得抗癌而不破壞機體免疫不再是空想。靶向治療已產生巨大的影響,我們期望我國能充分運用中西醫療法的優勢,為人類最終能攻克癌癥出一份力量。

PURPOSE: Given the activity and tolerability of pemetrexed/platinum combinations in non–small-cell lung cancer, and the success of novel therapeutic strategies employed in recent extensive-stage small-cell lung cancer (ES-SCLC) trials, a randomized phase II trial was initiated to evaluate the use of cisplatin or carboplatin plus pemetrexed in previously untreated ES-SCLC.
PATIENTS AND METHODS: Patients were randomly assigned to receive pemetrexed 500 mg/m2 plus cisplatin 75 mg/m2 or pemetrexed plus carboplatin area under the concentration curve 5. Treatment was administered once every 21 days for a maximum of six cycles. All patients received folic acid, vitamin B12, and steroid prophylaxis.
RESULTS: Between December 19, 2002, and May 17, 2004, 78 patients were enrolledonto this multicenter trial. Median age was 63 years (range, 46 to 82 years) for cisplatin/pemetrexed and 66 years (range, 47 to 75 years) for carboplatin/pemetrexed. Median survival time (MST) for cisplatin/pemetrexed was 7.6 months, with a 1-year survivorship of 33.4% and a response rate of 35% (95% CI, 20.6% to 51.7%). The MST for carboplatin/pemetrexed was 10.4 months, with a 1-year survivorship of 39.0% and a response rate of 39.5% (95% CI, 24.0 to 56.6). Median time to progression for cisplatin/pemetrexed was 4.9 months and for carboplatin/pemetrexed was 4.5 months. Median dose-intensity (actual/planned dose) was 98.94% for cisplatin and 99.95% for pemetrexed in the cisplatin/pemetrexed group and 93.21% for carboplatin and 98.50% for pemetrexed in the carboplatin/pemetrexed group. Grade 3/4 hematologic toxicities included neutropenia (15.8% v 20.0%) and thrombocytopenia (13.2% v 22.9%) in the cisplatin/pemetrexed and carboplatin/pemetrexed treatment groups, respectively.
CONCLUSION: Pemetrexed/platinum doublets had activity and appeared to be well-tolerated in first-line ES-SCLC.

Pemetrexed聯合順鉑或卡鉑一線治療廣泛期小細胞肺癌的II期隨機臨床試驗
目的:鑒于Pemetrexed聯合鉑類藥物治療非小細胞肺癌安全、有效,新近進行廣泛期小細胞肺癌的II期隨機臨床試驗引入了這一新的治療方案,目的是評估Pemetrexed聯合順鉑或卡鉑在未經治療的廣泛期小細胞肺癌治療中的應用!
患者和方法:患者隨機分成兩組,分別接受培美曲塞 500 mg/m2 加 順鉑 75 mg/m2(以下簡稱順鉑組)和培美曲塞加卡鉑面積濃度曲線<5(以下簡稱卡鉑組)治療。給藥方法為每21天為1周期,每周期給一次最大劑量藥物,共6周期。所有患者同時給予葉酸、維生素B12,類固醇預防治療。
結果:從2002年12月19日到2004年5月17日,共78名患者參加這項多中心試驗。順鉑加培美曲塞組中位年齡63歲(年齡范圍從46-82歲),卡鉑加培美曲塞組中位年齡66歲(范圍從47-75歲)。前組中位生存期為7.6個月,1年生存率為33.4%,有效率為35%。后組中位生存期為10.4個月,1年生存率為39%,有效率39.5%,順鉑組中位進展期為4.9個月,卡鉑組為4.5個月,中位最大劑量(實際應用/計劃劑量)在順鉑組,順鉑劑量為計劃劑量的98.94%,培美曲塞99.95%;卡鉑組卡鉑為93.21%,培美曲塞98.50%。兩組3~4級血液毒性反應包括中性粒細胞減少癥發生率分別為15.8%和20.0%,血小板減少癥發生率分別為13.2%和22.9%。
結論:培美曲塞聯合鉑類藥物一線治療小細胞肺癌有效且耐受良好。
