RESUMO

BACKGROUND: Evidence on adjuvant chemotherapy in older women with breast cancer is poor. We tested whether weekly docetaxel is more effective than standard chemotherapy. PATIENTS AND METHODS: We carried out a multicenter, randomized phase III study. Women aged 65-79, operated for breast cancer, with average to high risk of recurrence, were allocated 1 : 1 to CMF (cyclophosphamide 600 mg/m², methotrexate 40 mg/m², fluorouracil 600 mg/m², days 1, 8) or docetaxel (35 mg/m(2) days 1, 8, 15) every 4 weeks, for four or six cycles according to hormone receptor status. Primary end point was disease-free survival (DFS). A geriatric assessment was carried out. Quality of life (QoL) was assessed with EORTC C-30 and BR-23 questionnaires. RESULTS: From July 2003 to April 2011, 302 patients were randomized and 299 (152 allocated CMF and 147 docetaxel) were eligible. After 70-month median follow-up, 109 DFS events were observed. Unadjusted hazard ratio (HR) of DFS for docetaxel versus CMF was 1.21 [95% confidence interval (CI) 0.83-1.76, P = 0.32]; DFS estimate at 5 years was 0.69 with CMF and 0.65 with docetaxel. HR of death was 1.34 (95% CI 0.80-2.22, P = 0.26). There was no interaction between treatment arms and geriatric scales measuring patients' ability or comorbidities. Hematological toxicity, mucositis and nausea were worse with CMF; allergy, fatigue, hair loss, onychopathy, dysgeusia, diarrhea, abdominal pain, neuropathy, cardiac and skin toxicity were worse with docetaxel. One death was attributed to CMF and two to docetaxel. Increasing age, impairment in instrumental daily living activities, number of comorbidities and docetaxel treatment were independently associated with severe nonhematological toxicity. QoL was worse with docetaxel for nausea-vomiting, appetite loss, diarrhea, body image, future perspective, treatment side-effects and hair loss items. CONCLUSIONS: Weekly docetaxel is not more effective than standard CMF as adjuvant treatment of older women with breast cancer and worsens QoL and toxicity. CLINICALTRIALSGOV: NCT00331097.

RESUMO

Thirty llamas were used to study the effect of a 90 day feed supplementation on meat quality, chemical composition and muscle fatty acid profile. Treatments were: GR=llama on native pasture until slaughter; GR+SH=like GR, but with overnight free access to barley/alfalfa hay; and GR+SC=like GR, but with overnight free access to a wheat bran/sorghum grain concentrate. The supplementation had no effect on postmortem pH and temperature decline in the Longissimus lumborum muscle (LLM), cooking losses nor Warner-Bratzler shear force values (P>0.05). Meat from GR+SC llama had higher fat content in LLM (P<0.05) compared to GR and GR+SH llama. Intramuscular fat from GR+SH llama showed higher (P<0.01) proportions of polyunsaturated fatty acids, higher (P<0.05) polyunsaturated fatty acids/saturated fatty acids and desirable fatty acids ratio, lower (P<0.05) omega-6/omega-3 (n-6/n-3) ratio, and higher (P<0.01) conjugated linoleic acid.

RESUMO

BACKGROUND: To measure bone mineral density (BMD) reduction produced by letrozole as compared with tamoxifen and the benefit of the addition of zoledronic acid. PATIENTS AND METHODS: A phase 3 trial comparing tamoxifen, letrozole or letrozole+zoledronic acid in patients with hormone receptor-positive early breast cancer was conducted; triptorelin was given to premenopausal patients. Two comparisons were planned: letrozole versus tamoxifen and letrozole+zoledronic acid versus letrozole. Primary end point was the difference in 1-year change of T-score at lumbar spine (LTS) measured by dual energy X-ray absorptiometry scan. RESULTS: Out of 483 patients enrolled, 459 were available for primary analyses. Median age was 50 (range 28-80). The estimated mean difference (95% confidence interval [CI]) in 1-year change of LTS was equal to -0.30 (95% CI -0.44 to -0.17) in the letrozole versus tamoxifen comparison (P<0.0001) and to +0.60 (95% CI +0.46 to +0.77) in the letrozole+zoledronic acid versus letrozole comparison (P<0.0001). Bone damage by letrozole decreased with increasing baseline body mass index in premenopausal, but not postmenopausal, patients (interaction test P=0.004 and 0.47, respectively). CONCLUSIONS: In the HOBOE (HOrmonal BOne Effects) trial, the positive effect of zoledronic acid on BMD largely counteracts damage produced by letrozole as compared with tamoxifen. Letrozole effect is lower among overweight/obese premenopausal patients.

RESUMO

The effect of Isabel (IGE) and Niagara (NGE) grape seed and peel extracts on lipid oxidation, instrumental colour, pH and sensory properties of raw and cooked processed chicken meat stored at -18°C for nine months was evaluated. The pH of raw and cooked samples was not affected by the addition of grape extracts. IGE and NGE were effective in inhibiting the lipid oxidation of raw and cooked chicken meat, with results comparable to synthetic antioxidants. The extracts caused alterations in colour, as evidenced by the instrumental (darkening and lower intensity of red and yellow colour) and sensory results of cooked samples. In the sensory evaluation of odour and flavour, IGE produced satisfactory results, which did not differ from synthetic antioxidants. These findings suggest that the IGE and NGE are effective in retarding lipid oxidation of raw and cooked chicken meat during frozen storage.

RESUMO

The aims of this multicentre, randomised phase III trial were to evaluate: (1) the role of levamisol (LEV); and (2) the role of folinic acid (FA), added to 5-fluorouracil (5FU) in the adjuvant treatment of colorectal cancer. Patients with histologically proven, radically resected stage II or III colon or rectal cancer were eligible. The study had a 2x2 factorial design with four treatment arms: (a) 5FU alone, (b) 5FU+LEV, (c) 5FU+FA, (d) 5FU+LEV+FA, and two planned comparisons, testing the role of LEV and of FA, respectively. From March 1991, to September 1998, 1327 patients were randomised. None of the two comparisons resulted in a significant disease-free (DFS) or overall (OAS) survival advantage. The hazard ratio (HR) of relapse was 0.89 (95% confidence intervals (CI): 0.73-1.09) for patients receiving FA and 0.99 (95% CI 0.80-1.21) for those receiving LEV; corresponding HRs of death were 1.02 (95% CI: 0.80-1.30) and 0.94 (95% CI 0.73-1.20). Nonhaematological toxicity (all grade vomiting, diarrhoea, mucositis, congiuntivitis, skin, fever and fatigue) was significantly worse with FA, while all other toxicities were similar. In the present trial, there was no evidence that the addition of FA or LEV significantly prolongs DFS and OAS of radically resected colorectal cancer patients.

RESUMO

Azelastine, a phthalazinone derivative, is a new potent, long acting, orally active anti-allergic compound with particularly strong H1-histamine receptor antagonistic effects which has been proven to possess in vitro and in vivo a number of anti-inflammatory properties. The aim of the present study was to investigate whether azelastine would be able to prevent and/or reverse the seasonal increase in non-specific bronchial responsiveness to methacholine in pollen allergic patients. Twelve atopic patients (5 males, mean age 31 years), skin positive exclusively to grass and/or Parietaria pollen extract, with rhinitis and mild asthma occurring in the spring for at least two years previously, were studied. After a 2 week run-in period, oral azelastine, 4 mg twice daily, or placebo, was given for 2 weeks from the start of the pollen season, according to a randomized, double-blind design. After 2 weeks, the treatments were crossed over. During both the run-in and study periods, patients recorded rhinitis and asthma symptoms, additional antihistamine and bronchodilator drugs taken and peak expiratory flow measurements. A methacholine inhalation test was carried out on four occasions in each patient: before the run-in period, before the start of the treatment, and at the end of the two 2 week treatment periods. Azelastine significantly reduced rhinitis symptoms and the need for antihistamine drugs, whereas asthmatic symptoms, use of bronchodilator drugs, peak flow recordings and bronchial responsiveness to methacholine were unaffected by the treatment. Compliance level and adverse side-effects were not significantly different between active treatment and placebo. In the final subjective evaluation of the two treatments, eight out of 12 patients preferred azelastine.(ABSTRACT TRUNCATED AT 250 WORDS)

RESUMO

The prognostic role of drug-induced amenorrhea (DIA) was restrospectively evaluated in 221 out of 254 consecutive premenopausal patients treated with adjuvant CMF or a CMF-containing regimen; 33 patients were eliminated because of lack of menstrual data. All patients had metastatic axillary nodes; drug regimens were: CMF x 9 courses +/- Tamoxifen (TM) and CMF x 6 courses; median age was 43 (range 26-54). Premenopausal status was defined as last normal menses within the 6 weeks preceding initiation of chemotherapy: DIA as cessation of menses for at least 3 months not later than 3 months from the end of chemotherapy. DIA occurred in 166,221 (75.1%) patients and was strictly related to the age of the patients; also, the older the patients the shorter the time required to develop DIA. At median follow up of 69 months, Mantel-Byar analysis showed a longer disease free survival (DFS) for patients who developed DIA as compared with non amenorrheic women (P less than 0.001). DIA prognostic value was independent of age, number of involved nodes, tumour size and number of CMF cycles, as assessed by the Cox model (RH 0.43, 95% C.I. 0.24-0.77), in which DIA was entered as a time dependent covariate.

RESUMO

Treatment with tamoxifen (TM), alone or in combination with cyclophosphamide, methotrexate, and fluorouracil (CMF), was used as an adjuvant to surgery in 433 patients with stage I, II, or III(T3a) breast cancer. Oestrogen receptors (ER) and progesterone (PgR) receptors were assayed in most cases. 308 premenopausal node-negative and postmenopausal node-negative or node-positive patients were randomised to receive TM, 30 mg daily for 2 years, or no further therapy. 125 premenopausal node-positive patients were randomised to receive either CMF for nine courses plus TM or CMF alone. After a median follow-up of 63 months TM significantly reduced the incidence of relapses and deaths compared with no therapy. A significant interaction between treatment effect and ER/PgR status was seen. Disease-free and overall survival were similar after treatment with CMF+ TM or CMF.
