0引言乳腺癌是妇女最常见的恶性肿瘤之一,近年来其发病率在全世界范围内呈逐年上升趋势[1].现代乳腺癌治疗模式已形成局部治疗和全身治疗并重的综合治疗模式[2],但全身化疗不良反应明显,且在局部不易形成高浓度,对腋窝淋巴结的影响不大[3].而局部化疗可以在肿瘤部位达到很高的药物浓度,从而更好的发挥化疗药物的抗肿瘤作用[4-5].因此如何选择一种能够有效抑制亚临床病灶,降低复发率的局部化疗方法,成为乳腺癌治疗成败的关键.我们选择术中植入缓释氟尿嘧啶间质化疗,取得了较好的效果,现报告如下. 相似文献

PVI 5FU gives increased response rates and reduced toxicity when compared to bolus 5FU (J Clin Oncol 1989, 425-432). PVI 5FU administration was reported to give highly variable (>1000-fold) plasma 5FU concentrations at steady state (FU Css) which correlated with toxicity (Ann Oncol 1996, 47-53); but only 19 patients were studied. Therefore, we performed a study of PVI 5FU in 61 patients with advanced colorectal cancer to assess the variability (inter- and intra-subject) in 5FU Css associated with PVI 5FU (300 mg m(-2)day(-1)) and to attempt to correlate pharmacodynamic end-points (anti-tumour activity, toxicity) with 5FU Css as a prelude to 'exposure-guided' 5FU administration. All 5FU sampling was performed between 10 am and noon. PVI 5FU administration continued to 26 weeks in patients with disease improvement or stabilization. The response rate was 26% (33% stable disease) and median survival was 11 months. Hand-foot syndrome was the most common dose limiting toxicity. Variability in 5FU(300)Css was considerably less than previously reported; 94 +/- 25 ng ml(-1)(CV = 27%). No relationships were demonstrated between subject mean 5FU(300)Css and PD end-points such as response, mucositis, diarrhoea and hand-foot syndrome. The lack of correlation suggests that measurement of 5FU concentrations should not be used to individualize dosing in patients receiving PVI 5FU for advanced colorectal cancer. 相似文献

Survival after adjuvant 5-FU treatment for stage III colon cancer in hereditary nonpolyposis colorectal cancer 总被引:5,自引:0,他引:5
de Vos tot Nederveen Cappel WH Meulenbeld HJ Kleibeuker JH Nagengast FM Menko FH Griffioen G Cats A Morreau H Gelderblom H Vasen HF 《International journal of cancer. Journal international du cancer》2004,109(3):468-471
In vitro studies suggest that a deficient mismatch repair (MMR) system reduces 5-Fluorouracil cytotoxicity. Colon cancer (CC) in hereditary nonpolyposis colorectal cancer (HNPCC) is due to a dysfunctioning MMR gene that leads to microsatellite instability (MSI). Clinical studies on the efficacy of 5-Fluorouracil (5-FU) in MSI high tumours are contradictory. In a retrospective study, we compared the survival of subjects with stage III CC from HNPCC families that were treated with and without adjuvant 5-FU. The Dutch HNPCC family registry was used. Information on adjuvant chemotherapy for stage III CC was obtained from subjects of families with a mutation and/or who fulfilled the AMS criteria or who were strongly suspicious for HNPCC. CC specific survival was calculated. Observation time was measured either until the date of death, date of a second primary CC or until the closing date of the study, i.e., June 1, 2001. Statistical analysis was done by Kaplan-Meier survival analysis. A total of 92 subjects with stage III CC were included. Twenty-eight of them (17 males) had adjuvant treatment with 5-FU. The median follow-up was 4 (range: 1-17) years; 8 subjects died of CC. The 5-year survival was 70% (95% Cl: 49-90). Sixty-four subjects (36 males) did not have adjuvant therapy. Their median follow-up was 6 (range: 0-23) years. Twenty of them died of CC. The 5-year survival in this group was also 70% (95% Cl: 59-83). To date, the selection of patients with CC for 5-FU treatment is based on the stage rather than the biology of the tumour. In our study, the 5-year survival of subjects treated with and without adjuvant 5-FU did not differ. Further studies are necessary to elucidate the role of MSI in 5-FU treatment of MSI-H tumours in HNPCC. 相似文献

Background: To determine the maximum tolerable dose (MTD) and therapeutic activity of MTHF-modulated FU using two different administration schedules of the antimetabolite (bolus vs. two-hour infusion), the present randomized study using a 'pick-the-winner' design was undertaken in patients with advanced colorectal cancer.Patients and methods: Eighty-two patients with previously untreated advanced measurable colorectal cancer were randomly assigned to treatment with MTHF (100 mg/m2 days 1–5 i.v. bolus) plus FU (400 mg/m2 days 1–5) given either as i.v. bolus injection or as a two-hour infusion every four weeks. In the absence of dose-limiting toxicity (DLT, defined as WHO grade 3 hematotoxicity and/or WHO grade 2 nonhematologic side effects) and evidence of progressive disease, the FU dose was escalated by 50 mg/m2/day during each subsequent cycle until the individual maximum tolerable dose (MTD) was reached.Results: Forty patients were randomized to the FU bolus arm and 42 patients to the FU two-hour infusion arm. The median MTD was 475 mg/m2/day (95% CI: 450–500) in the FU bolus arm with stomatitis ± diarrhea being the most common DLT. Gastrointestinal side effects were also dose-limiting in the two-hour infusion arm; however, the median MTD was 600 mg/m2/day (95% CI: 568–632). Myelosuppression was more pronounced in the FU bolus arm than in the two-hour infusion arm. The overall response rates were 27.5% (95% CI: 15–44%; 1 CR and 10 PR) for patients treated in the bolus arm and 14.5% (95% CI: 5–28%; 1 CR and 5 PR) for those treated in the two-hour infusion arm. Analogous to recorded response, median time to progression (8.5 vs. 6.25) and overall survival time (14.0 vs. 11.0) tended to be superior in the FU bolus arm.Conclusions: The observed differences in tolerable drug dose and toxicity between the two treatment arms might be explained by the administration schedule-dependent clinical pharmacokinetics of FU and/or the difference in extent of biochemical modulation of the antimetabolite through MTHF. The fact that the two regimens were not equitoxic probably also helps to explain the favourable response activity noted in the MTHF/FU bolus arm. Whether MTHF is as effective as leucovorin for biochemical modulation of FU remains to be determined in a randomized trial, for which we would recommend its combined use with bolus FU ('winner arm') using a starting dose of 400 mg/m2/day ×5. 相似文献

We studied the role of TS (5’VNTR, 5’SNP and 3’UTR), XRCC1-399, XPD-751, ERCC1-118 and XRCC3-241 genetic polymorphisms in tailoring fluroropyrimidine/oxaliplatin treatment. For this purpose, 110 XELOX (capecitabine/oxaliplatin)- or FUOX (fluorouracil/oxaliplatin)-treated metastatic colorectal cancer patients were selected prospectively for genotyping. In the FUOX group, TS-3’UTR +6 bp/+6 bp (hazards ratio, HR = 2.62, p = 0.007) and ERCC1-118 C/T or C/C (HR = 1.96, p = 0.050) genotypes correlated with a shorter progression free survival (PFS). When analysed jointly, the higher the number of favourable genotypes (FG) the longer the PFS (6.8 m, 9.6 m and 25.8 m for 0, 1 or 2 FG; p = 0.005). Disease-control rate was 100% in patients with 2 FG (87% and 38.5% for 1 or 0 FG; p = 0.001). In the multivariate analysis, ERCC1-118 (HR = 2.12, p = 0.0037) and TS-3’UTR (HR = 2.68, p = 0.006) were strong independent prognostic factors. According to this, patients harbouring TS-3’UTR +6 bp/+6 bp and ERCC1-118 C/T or C/C genotypes may better receive capecitabine instead of 5FU in an oxaliplatin-based first-line treatment. 相似文献
