PURPOSE: Elderly patients constitute a subpopulation with special characteristics that differ from those of the nonelderly and have been underrepresented in clinical trials. This study was performed to determine the efficacy and safety of irinotecan (CPT-11) in combination with fluorouracil (FU) administered as a 48-hour continuous infusion twice a month in elderly patients. PATIENTS AND METHODS: Patients > or = 72 years old with metastatic colorectal cancer, Eastern Cooperative Oncology Group performance status of 0 to 1, no geriatric syndromes, and no prior treatment were treated every 2 weeks with CPT-11 180 mg/m2 plus FU 3,000 mg/m2 in a 48-hour continuous infusion. RESULTS: By intent-to-treat analysis, in 85 assessable patients, the objective response rate was 35% (95% CI, 25% to 46%), and stable disease was 33% (95% CI, 23% to 44%). Median time to progression was 8.0 months (95% CI, 6.0 to 10.0 months), and median overall survival time was 15.3 months (95% CI, 13.8 to 16.9 months). Toxicity was moderate. Grade 3 and 4 neutropenia, diarrhea, and asthenia were observed in 21%, 17%, and 13% of patients, respectively. Only one case of neutropenic fever occurred. There were two toxic deaths, one was a result of grade 4 diarrhea and acute kidney failure, and the other was a result of massive intestinal hemorrhage in the first cycle. The study of prognostic factors did not reveal any predictive factor of response. Response to treatment and baseline lactate dehydrogenase were the main factors conditioning progression-free and overall survival. CONCLUSION: Twice a month continuous-infusion CPT-11 combined with FU is a valid therapeutic alternative for elderly patients in good general condition. 相似文献

Introduction
A prospective phase II study was conducted to assess the clinical activity and tolerability of oxaliplatin, capecitabine, and radiotherapy (RT) for neoadjuvant therapy of stages II?CIII rectal cancer.Materials and methods
Patients with histologically confirmed stages II?CIII (T3?CT4 and/or N+) resectable rectal adenocarcinoma were eligible. Capecitabine was administered at 825?mg/m2 twice daily for 5?days/week and oxaliplatin at 50?mg/m2 on day 1 weekly for 5?weeks starting the first day of RT (before RT). RT consisted of a total dose of 45?Gy delivered in 25 fractions of 1.8?Gy, 5?days per week, for 5?weeks.Results
A total of 46 patients were included (35 male, 10 female, median age 62?years). TNM Stage was T3 in 43 patients and T4 in 2. Twenty-eight patients had suspected nodal involvement. The intended chemoradiation treatment was completed in 94?% patients. Grade 3/4 toxicity included lymphocytopenia (6 patients), diarrhea (4 patients), emesis (2 patients), asthenia (3 patients), anorexia (1 patient), and hepatic toxicity (1 patient). Grade 1 neurotoxicity occurred in 18 patients, Grade 2 neurotoxicity in 3, and Grade 1 palmoplantar erythrodysesthesia in 2. Forty-two patients underwent surgery (complete resection 95?%, sphincter-saving operation 55?%). The overall pathologic response rate was 83?%, with a pathologic complete response (pCR) rate of 11.9?% (95?% CI 4.0?C25.6).Conclusions
The pCR rate observed with oxaliplatin plus capecitabine and RT did not reach the pre-specified criteria of efficacy in this trial, which is in line with recent results of randomized phase III trials. 相似文献3.

ObjectiveTest effectiveness and acceptability of interventions short essay-type training in health emergency management (EM).DesignCombined case series and controlled study before and after training sessions.LocationHealth Center (HC).ParticipantsTeam on duty, two monitors-facilitators, and a mannequin.Main measuresVariables: response times, staff performance, resource usage and opinion. Structure: scenarios and key messages. Instrument development: 1. Initial/final questionnaire and events. 2. Essential/non-essential times; 3. Post-test opinion questionnaire. Performance of six consecutive 15 min tests fortnightly (including corrections) and poll after each test. A month later, repeat in random order and under similar conditions. Analysis: repeated measures.ResultsA total of 93 (2/3) workers completed the initial survey, and 74 the final, with 46 participants (25 doctors, 7 nurses, 21 non-health completed 95 direct interventions. Matching participants > 80% between series. A reduction was seen in the “detection of collapse to first defibrillation” interval (10 to 4 min). EM events improved 2-3 fold and “sense of security during a real EM” increased from 23% to 71% among participants. The vast majority of participants said “useful corrections made by the facilitator.” The proportions of those who “would like to see tests introduced” and those who said “re-training was needed in EM” were moderately increased (67.4% vs 85% in health care workers). The “would like to attempt basic life support” was unchanged.ConclusionDespite being reduced in number and duration, this model of intervention has shown positive trends in terms of use and acceptability for implementation in the HC. 相似文献

Background:
The impact of thymidylate synthase (TYMS) and UDP-glucoronosyltransferase 1A (UGT1A) germline polymorphisms on the outcome of colorectal cancer (CRC) patients treated with irinotecan plus 5-fluorouracil (irinotecan/5FU) is still controversial. Our objective was to define a genetic-based algorithm to select patients to be treated with irinotecan/5FU.Methods:
Genotyping of TYMS (5′TRP and 3′UTR), UGT1A1*28, UGT1A9*22 and UGT1A7*3 was performed in 149 metastatic CRC patients treated with irinotecan/5FU as first-line chemotherapy enrolled in a randomised phase 3 study. Their association with response, toxicity and survival was investigated by univariate and multivariate statistical analysis.Results:
TYMS 3TRP/3TRP genotype was the only independent predictor of tumour response (OR=5.87, 95% confidence interval (CI)=1.68–20.45; P=0.005). UGT1A1*28/*28 was predictive for haematologic toxicity (OR=6.27, 95% CI=1.09–36.12; P=0.04), specifically for neutropenia alone (OR=6.40, 95% CI=1.11–37.03; P=0.038) or together with diarrhoea (OR=18.87, 95% CI=2.14–166.67; P=0.008). UGT1A9*1/*1 was associated with non-haematologic toxicity (OR=2.70, 95% CI=1.07–6.82; P=0.035). Haplotype VII (all non-favourable alleles) was associated with non-haematologic toxicity (OR=2.11, 95% CI=1.12–3.98; P=0.02).Conclusion:
TYMS and UGT1A polymorphisms influence on tumour response and toxicities derived from irinotecan/5FU treatment in CRC patients. A genetic-based algorithm to optimise treatment individualisation is proposed. 相似文献10.
