Summary This study set out to evaluate, in patients with metastatic colorectal carcinoma, the efficacy and toxicity of S-1, which contains tegafur, 5-chloro-2,4-dihydroxypyridine (CDHP) and potassium oxonate, based on a biochemical modulation of 5-fluorouracil (5-FU) targeted at inhibition of dihydropyrimidine dehydrogenase (DPD). Sixty-three patients with measurable metastatic colorectal carcinoma were enrolled into the study. None of the patients had received prior chemotherapy except for adjuvant setting. S-1 was administered orally twice daily at a (R)C (R)C standard dose of 80mg m day for 28 days followed by a 14-day rest. This agent is continued until disease progression, unaccepted toxicity, or patient refusal. Twenty-two (35%) of the 62 eligible patients achieved PR with a 95% confidence interval of 25(R)C48. Five of the 10 patients with a history of adjuvant chemotherapy achieved partial remission. The median survival time was 12 months. Major adverse reactions included myelosuppressive and gastrointestinal toxicities, though their incidence of grade 3 or 4 being 13% in neutropenia and less than 10% in the others. None of the 53 patients treated as outpatients required hospitalization due to adverse reactions: These results suggest that S-1 achieves similar responses to those of infusional 5-FU plus leucovorin and shows the potential of another biochemical modulation with easily manageable toxicity. |

試試看 摘要:本研究旨在評測含有替加氟,5-氯-2,4-二羥基吡啶(CDHP)和氧嗪酸鉀的S-1對于轉移性結腸直腸癌病人的療效和毒副作用。這項評測是以5 - 氟尿嘧啶(5-FU)有針對性的抑制二氫嘧啶脫氫酶(DPD)這種生化調解作用為基礎的。63位檢測有轉移性大腸癌的病人參加了這項研究。除了輔助治療外,這些病人之前沒有接受過任何化療。病人們首先連續(xù)28天每日兩次按照(R)C(R)C標準劑量口服80mg S-1,接下來14天進行休息。這項療程持續(xù)進行到疾病擴展、出現(xiàn)不可接受的毒性作用或者病人拒絕為止。62位符合條件的病人中有22個(35%)達到了95%的25(R)C48置信區(qū)間的PR比。10位有過輔助化療歷史的病人中有5位實現(xiàn)了部分緩解。中位生存期為12個月。主要不良反應包括骨髓抑制和胃腸道毒性,但其3或4級發(fā)病率為13%的中性粒細胞減少,和10%的胃腸道毒性。作為門診病人的53位患者沒有因為不良反應而需要住院的。這些結果表明S-1能夠實現(xiàn)與注射5-FU加甲酰四氫葉酸類似的反應,并且顯示了這是一種毒性易控的生化調解方法。 |
