Context: The aim of the project was to identify clinical and quality of life (QL) factors that together predict survival and response to chemotherapy in advanced breast cancer. Potential prognostic factors were studied in 187 women with baseline QL data from a trial of paclitaxel versus doxorubicin as first-line chemotherapy. Demographic and clinical factors studied were age, performance status, dominant site of disease and preceding disease-free interval (DFI). Factors from the EORTC QLQ-C30 were all function scales, fatigue, nausea/vomiting, pain, dyspnoea, insomnia, loss of appetite and global QL. The proportional hazards regression model with stratification for treatment, and the logistic regression model adjusting for treatment arm were used for univariate and multivariate analyses of survival and response to treatment, respectively. For survival, multiple sites of visceral disease, pain, global QL and fatigue were significant prognostic factors in the univariate analysis. The final multivariate model predicted poor survival with multiple sites of visceral disease (P=0.003), DFI </=2 years (P=0.026) and pain (P=0.003). For response, age, dyspnoea, fatigue and global QL were significant predictive factors in the univariate analysis. The final multivariate model for response selected DFI (P=0.009), multiple sites of visceral disease (P=0.037) and dyspnoea (P=<0.001) using forward selection, but model instability was indicated by the inclusion of fatigue and emotional function in the final model when backward selection was used. In addition to known clinical factors, patient-assessed QL variables appear to be prognostic for survival and response to chemotherapy in women with advanced breast cancer. However, identification of prognostic factors from responses to questionnaires may be unstable, and their reliability and clinical utility should be tested prospectively.

Context: To assess whether omission of postoperative radiotherapy in women with 'low-risk' axillary node negative breast cancer (T0-2) treated by breast-conserving surgery and endocrine therapy improves quality of life and is more cost-effective. A randomised controlled clinical trial, using a method of minimisation balanced by centre, grade of cancer, age, lymphatic/vascular invasion and preoperative endocrine therapy, was performed. A non-randomised cohort was also recruited, in order to complete a comprehensive cohort study. The setting was breast cancer clinics in cancer centres in the UK. Patients aged 65 years or more were eligible provided that their cancers were considered to be at low risk of local recurrence, were suitable for breast-conservation surgery, were receiving endocrine therapy and were able and willing to give informed consent. The standard treatment of postoperative breast irradiation or the omission of radiotherapy. Quality of life was the primary outcome measure, together with anxiety and depression and cost-effectiveness. Secondary outcome measures were recurrence rates, functional status, treatment-related morbidity and cosmesis. The principal method of data collection was by questionnaire, completed at home with a research nurse at four times over 15 months. The hypothesised improvement in overall quality of life with the omission of radiotherapy was not seen in the EuroQol assessment or in the functionality and symptoms summary domains of the European Organisation for Research in the Treatment of Cancer (EORTC) scales. Some differences were apparent within subscales of the EORTC questionnaires, and insights into the impact of treatment were also provided by the qualitative data obtained by open-ended questions. Differences were most apparent shortly after the time of completion of radiotherapy. Radiotherapy was then associated with increased breast symptoms and with greater fatigue but with less insomnia and endocrine side-effects. Patients had significant concerns about the delivery of radiotherapy services, such as transport, accommodation and travel costs associated with receiving radiotherapy. By the end of follow-up, patients receiving radiotherapy were expressing less anxiety about recurrence than those who had not received radiotherapy. Functionality was not greatly affected by treatment. Within the randomised controlled trial, the Barthel Index demonstrated a small but significant fall in functionality with radiotherapy compared with the no radiotherapy arm of the trial. Results from the non-randomised patients did not confirm this effect, however. Cosmetic results were better in those not receiving radiotherapy but this did not appear to be an important issue to the patients. The use of home-based assessments by a research nurse proved to be an effective way of obtaining high-quality data. Costs to the NHS associated with postoperative radiotherapy were calculated to be of the order of 2000 pounds per patient. In the follow-up in this study, there were no recurrences, and the quality of life utilities from EuroQol were almost identical. Although there are no differences in overall quality of life scores between the patients treated with and without radiotherapy, there are several dimensions that exhibit significant advantage to the omission of irradiation. Over the first 15 months, radiotherapy for this population is not a cost-effective treatment. However, the early postoperative outcome does not give a complete answer and the eventual cost-effectiveness will only become clear after long-term follow-up. Extrapolations from these data suggest that radiotherapy may not be a cost-effective treatment unless it results in a recurrence rate that is at least 5% lower in absolute terms than those treated without radiotherapy. Further research is needed into a number of areas including the long-term aspects of quality of life, clinical outcomes, costs and consequences of omitting radiotherapy

Context: To compare the efficacy and safety of tafluprost, a preservative-free (PF) prostaglandin analogue, with PF timolol in patients with open-angle glaucoma or ocular hypertension.\nRandomized, double-masked, multicenter clinical trial.\nAfter discontinuation and washout of existing ocular hypotensive treatment, patients who had intraocular pressure (IOP) =23 and =36 mm Hg in at least 1 eye at the 08:00 hour time point were randomized 1:1 to 12 weeks of treatment with either PF tafluprost 0.0015% or PF timolol 0.5%. IOP was measured 3 times during the day (08:00, 10:00, 16:00 hours) at baseline and at weeks 2, 6, and 12. It was hypothesized that PF tafluprost would be noninferior to PF timolol over 12 weeks with regard to change from baseline IOP. The trial was powered for a noninferiority margin of 1.5 mm Hg at each of the 9 time points assessed.\nA total of 643 patients were randomized and 618 completed (PF tafluprost = 306, PF timolol = 312). IOPs at the 3 time points assessed during the baseline visit ranged from 23.8 to 26.1 mm Hg in the PF tafluprost group and 23.5 to 26.0 mm Hg in the PF timolol group. IOPs at the 3 time points assessed during the 12-week visit ranged from 17.4 to 18.6 mm Hg for PF tafluprost and 17.9 to 18.5 mm Hg for PF timolol. At all 9 time points, the upper limits of the 2-sided 95% confidence intervals for the difference between treatments in IOP lowering were less than the prespecified noninferiority margin. Similar percentages of PF tafluprost and PF timolol patients reported ocular pain/stinging/irritation (4.4% vs 4.6%) and pruritus (2.5% vs 1.5%). The percentages of PF tafluprost and PF timolol patients reporting conjunctival hyperemia were 4.4% vs 1.2% (nominal P = .016).\nThe IOP-lowering effect of PF tafluprost was noninferior to that of PF timolol. PF tafluprost is an efficacious and generally well-tolerated ocular hypotensive agent.

Context: In advanced not selected NSCLC chemotherapy achieved an advantage of approximately 1-2 months on median survival versus best supportive care. Chemotherapy seems to improve symptoms control, even if randomised studies with quality of life as first endpoint are lacking and often chemotherapy toxicity compromises the frail cost/benefit ratio. The aim of the present study is to evaluate the impact on QoL, substituting cisplatin, a pivot drug in NSCLC therapy, with carboplatin, an analogue with an improved toxicity profile. The combination of cisplatin with Mitomycin and Vinblastine was one of the most frequently used in the palliative setting at the time of design of our study. Patients were randomized to receive MVP regimen (Mitomycin-C 8 mg/m2 d1, Vinblastine 4 mg/m2 d 1-8, Cisplatin 100 mg/m2 d1) or MVC regimen (Mitomycin-C 8 mg/m2 d1, Vinblastine 4 mg/m2 d 1-8, Carboplatin 300 mg/m2 d1) every 3 weeks. The QoL was evaluated by the Spitzer QL-Index and by the EORTC QLQ-C30+LC 13 questionnaires before chemotherapy, after one cycle, after three cycles, and then every 6 weeks in the first 6 months and every 3 months thenafter. From September 1994 to July 1997, 153 consecutive patients were randomized to MVP (75 patients) or MVC arm (78 patients). Despite difficulties in carrying out and analysing QoL items in such patients, the global QoL evaluated by the Spitzer's questionnaire suggested an advantage for MVC regimen (P=0.05) and a significant difference was observed in global health subdomain (P=0.04). The disease-related symptoms improved with time, and the benefits lasted for the entire treatment period. When evaluated with the EORTC questionnaire there was significantly less nausea and vomiting (P=0.0001), appetite loss (P=0.01), insomnia (P=0.03), constipation (P=0.01) and peripheral neuropathy (P=0.01) in favour of MVC, and a trend for less hair loss (P=0.05). The advantage lasted for all the duration of chemotherapy. No differences were observed in global quality of life subdomain (P=0.40) between the two regimen. QoL was the first endpoint and the statistical power was inadequate to assess other parameters. However, we reported a response rate of 43.1 and 38.6%, respectively, in MVP and MVC arm (P=0.59) and a median survival of 10.2 and 7.2 months, respectively, for cisplatin and carboplatin arm (P=0.39). The carboplatin containing regimen (MVC) has a significant better toxicity profile than the cisplatin containing (MVP) regimen as proven both by the EORTC questionnaires and by the WHO toxicity data reported by physicians. No significant differences in terms of response rate, time to progression and overall survival were observed between the two regimen. The two chemotherapy regimen showed a similar effectiveness in symptom palliation when evaluated with C30 addendum of EORTC QOL questionnaire. With the Spitzer's questionnaires a trend towards an improved quality of life index was observed during treatment with the carboplatin combination in comparison to the cisplatin combination. This difference, however, was not observed when the global quality of life was evaluated with the EORTC patients compiled questionnaires. A carboplatin containing regimen with better toxicity profile and a similar potentiality for symptoms control offers an option in comparison to similar cisplatin containing combinations in the palliative treatment of advanced NSCLC.
