Objective: The aim of the study was to investigate the prospective study if treatment with arsenic trioxide (As2O3) could enhance disease-free survival as adjuvant post-operative chemotherapy for gastric cancer patients and protect bone marrow from the negative effects of chemotherapy. Methods: 84 adults were randomized into two groups. Patients in treat- ment group were treated with As203 and FOLFOX regimen, the other were administered with FOLFOX regimen only. Results: Four patients were withdrawn in treatment group after 3-4 cycles and the reasons were headache and fidgety (n = 2), ar- rhythmia (n = 1) and AST/ALT elevation (n = 1), while 1 patient in control group after 4 cycles for neutropenia. In the treatment group, the median DFS was 28.34 months (95% CI, 25-33 months). While in control group, the median DFS was 24.50 months (95% CI, 20-30 months). This difference was not statistically significant (chi-square: 2.8885; P value: 0.0892). Pa- tients in the same subgroup of node-positive was 29 in the treatment group and 32 in control group, respectively. The median DFS was 27.87 months (95% CI, 25-31 months) in the treatment group and 24.18 months (95% CI, 19-31 months) in the control group with promising statistical significance (HR 1.89; chi-square: 4.78; P value: 0.0287). The most common grades 3-4 toxicity was leucopenia (n = 11) in control group and the difference was significant (chi-square: 3.9768, P value: 0.046) compared with that in treatment group (n = 4). Conclusion: The combination of arsenic trioxide and FOLFOX regimen has a potential advantage of enhancing disease-free survival in patients with gastric cancer in nodal-positive status as post-opera- tive chemotherapy, and protect bone marrow from the negative effects of chemotherapy. 相似文献

The efficacy of bevacizumab combined with infusional 5-fluorouracil/leucovorin (5-FU/LV) plus irinotecan (FOLFIRI) as the second-line treatment for metastatic colorectal cancer (mCRC) has not been fully clarified, although bevacizumab combined with infusional 5-FU/LV plus oxaliplatin (FOLFOX) in the second-line setting has demonstrated a survival benefit. We investigated the efficacy of bevacizumab plus FOLFIRI in mCRC patients who failed oxaliplatin-containing regimens without bevacizumab. Patients who received bevacizumab plus FOLFIRI or bevacizumab plus FOLFOX as second-line chemotherapy between July 2007 and March 2008 were registered (trial registration: UMIN000001547). Patient background data and progression-free survival (PFS), overall survival (OS), response, and bevacizumab-related adverse events were prospectively collected every 6?months. A total of 195 patients were enrolled from 26 institutions. Among them, 115 patients received bevacizumab plus FOLFIRI after failure of oxaliplatin and fluoropyrimidine (FOLFIRI+BV after OX/FU group), and 45 patients received bevacizumab plus FOLFOX after failure of irinotecan and fluoropyrimidine (FOLFOX+BV after IRI/FU group). Median PFS was 8.3?months (95% confidence interval [CI], 6.7-9.9) for the FOLFIRI+BV after OX/FU group and 7.8?months (95% CI, 5.8-9.7) for the FOLFOX+BV after IRI/FU group. Median OS was 21.6?months (95% CI, 17.6-25.6) and 16.5?months (95% CI, 11.8-21.2), respectively. Overall response rates were 25 and 29%, respectively. The most common grade ≥3 bevacizumab-related adverse events were hypertension (5.0%) and bleeding (3.8%). FOLFIRI+BV after OX/FU showed comparable efficacy to FOLFOX+BV after IRI/FU. 相似文献

Adjuvant therapy with chemotherapy and/or radiation therapy in addition to surgery improves outcome for patients with high-risk carcinomas of the colon or rectum. For colon cancer, fluorouracil (5-FU) combined with leucovorin is a current standard of care that improves long-term survival. A recent European trial (MOSAIC) has documented significant improvement in 3-year disease-free survival when oxaliplatin (Eloxatin) was added to infusional 5-FU and leucovorin in the FOLFOX regimen. Two US cooperative group trials will evaluate the addition of antiangiogenesis therapy with bevacizumab (Avastin) to chemotherapy. A third trial will evaluate FOLFOX, irinotecan (Camptosar) combined with infusional 5-FU and leucovorin (FOLFIRI), and the sequential use of FOLFOX followed by FOLFIRI. In rectal cancer, postoperative 5-FU-based chemotherapy combined with irradiation can improve both local tumor control and survival. The German Rectal Cancer Group has recently reported that preoperative combined-modality therapy is less toxic and more effective in preventing local tumor relapse compared to similar treatment given postoperatively. A coordinated pair of cooperative group clinical trials will evaluate oral capecitabine (Xeloda) as a radiation enhancer in the preoperative setting, and the FOLFOX and FOLFIRI regimens compared to 5-FU and leucovorin following surgery. Predictive and prognostic molecular markers will be studied in these new adjuvant therapy clinical trials for both colon and rectal cancer with the goal of developing future regimens tailored to individual patients. There has been a recent and dramatic increase in the pace of drug development for colorectal cancer which holds promise to further improve curative therapy as part of a multidisciplinary approach in the surgical adjuvant setting. 相似文献

Background:
There have been controversies in prognostic impact of mucinous histology on colorectal cancer, and its implication in patients treated with adjuvant 5-fluorouracil, leucovorin, and oxaliplatin (FOLFOX) is unclear.Methods:
Stage II and III colorectal cancer patients who underwent curative resection followed by adjuvant FOLFOX were included. Patients were grouped according to the mucinous content: >50%, mucinous adenocarcinoma (MAC); <50%, adenocarcinoma with intermediated mucinous component (AIM); and without any mucinous component, non-MAC (NMA). Clinicopathological features and disease-free survival (DFS) were compared.Results:
Among a total of 521 patients, 27 patients (5.2%) had MAC, 41 patients (7.9%) had AIM, and 453 patients (86.9%) had NMA. Mucinous adenocarcinoma and AIM had higher frequency of proximal location and microsatellite instability, but lower frequency of angiolymphatic invasion. Disease-free survival was significantly worse in the MAC compared with NMA (3-year DFS 57% and 86%, respectively; P<0.001) and AIM (3-year DFS 87%, P=0.01 vs MAC). Multivariate analysis revealed MAC as an independent negative prognostic factor of DFS (adjusted hazard ratio 7.96, 95% confidence interval 3.76–16.8).Conclusion:
Adenocarcinoma with intermediated mucinous component and MAC have distinct clinicopathological features compared with NMA. Mucinous adenocarcinoma has an adverse prognostic impact on stage II or III colorectal cancer treated with adjuvant FOLFOX. 相似文献17.

The sequential FOLFOX7–FOLFIRI combination is not superior to FOLFOX4 in colorectal cancer patients with resectable metastases. Patients with synchronous metastases preferably received perioperative chemotherapy, while patients with metachronous metastases were given postoperative chemotherapy in preference. We observed the highest long-term survival rates ever reported in this setting.BackgroundPerioperative FOLFOX4 (oxaliplatin plus 5-fluorouracil/leucovorin) chemotherapy is the current standard in patients with resectable metastases from colorectal cancer (CRC). We aimed to determine whether a sequential chemotherapy with dose-dense oxaliplatin (FOLFOX7) and irinotecan (FOLFIRI; irinotecan plus 5-fluorouracil/leucovorin) is superior to FOLFOX4. The chemotherapy timing was not imposed, and was perioperative or postoperative.Patients and methodsIn this open-label, phase III trial, patients with resectable or resected metastases were randomly assigned either to 12 cycles of FOLFOX4 (oxaliplatin 85 mg/m2) or 6 cycles of FOLFOX7 (oxaliplatin 130 mg/m2) followed by 6 cycles of FOLFIRI (irinotecan 180 mg/m2). Randomization was done centrally, with stratification by chemotherapy timing, type of local treatment (surgery versus radiofrequency ablation with/without surgery), and Fong's prognostic score. The primary end point was 2-year disease-free survival (DFS).ResultsA total of 284 patients were randomized, 142 in each treatment group. Chemotherapy was perioperative in 168 (59.2%) patients and postoperative in 116 (40.8%) patients. Perioperative chemotherapy was preferentially proposed for synchronous metastases, whereas postoperative chemotherapy was more frequently used for metachronous metastases. Two-year DFS was 48.5% in the FOLFOX4 group and 50.0% in the FOLFOX7–FOLFIRI group. In the multivariable analysis, more than one metastasis [hazard ratio (HR) = 2.15] and synchronous metastases (HR = 1.63) were independent prognostic factors for shorter DFS. Five-year overall survival (OS) rate was 69.5% with FOLFOX4 versus 66.6% with FOLFOX7–FOLFIRI.ConclusionsFOLFOX7–FOLFIRI is not superior to FOLFOX4 in patients with resectable metastatic CRC. Five-year OS rates observed in both groups are the highest ever reported in this setting, possibly reflecting the pragmatic approach to chemotherapy timing.Clinical trials numberNCT00268398. 相似文献
