Type does matter. Use VIRGIN olive oil as your preferred fat to reduce your risk of breast cancer: case-control EpiGEICAM study.

The Epi-GEICAM study comprises 1017 invasive BC cases matched with controls of similar age (49 ± 9 years) and residence. Diet and OO consumption were collected through a validated food frequency questionnaire. 75% of women referred OO, common (refined) or virgin, as the main fat source. Using conditional logistic regression models, we compared different scenarios of type and frequency of OO consumption, using as reference those women not always using OO for the three culinary practices (seasoning, cooking, and frying) and adding <2 tablespoons (tbsps.) per day during the meal to bread, salad, or dishes. A substantial inverse association was observed in those women always using VOO for the three culinary practices and consuming ≥2 tbsps. of OO per day during meals (adjusted OR, 0.72; 95% CI: 0.51, 1.03; P = 0.07). Potential benefits from OO consumption, at least as regards the protection provided for BC, could be mostly conferred with VOO, and when its consumption is high.

Trajectories of alcohol consumption during life and the risk of developing breast cancer.

BACKGROUND: Whether there are lifetime points of greater sensitivity to the deleterious effects of alcohol intake on the breasts remains inconclusive. OBJECTIVE: To compare the influence of distinctive trajectories of alcohol consumption throughout a woman's life on development of breast cancer (BC). METHODS: 1278 confirmed invasive BC cases and matched (by age and residence) controls from the Epi-GEICAM study (Spain) were used. The novel group-based trajectory modelling was used to identify different alcohol consumption trajectories throughout women's lifetime. RESULTS: Four alcohol trajectories were identified. The first comprised women (45%) with low alcohol consumption (<5 g/day) throughout their life. The second included those (33%) who gradually moved from a low alcohol consumption in adolescence to a moderate in adulthood (5 to <15 g/day), never having a high consumption; and oppositely, women in the third trajectory (16%) moved from moderate consumption in adolescence, to a lower consumption in adulthood. Women in the fourth (6%) moved from a moderate alcohol consumption in adolescence to the highest consumption in adulthood (≥15 g/day), never having a low alcohol consumption. Comparing with the first trajectory, the fourth doubled BC risk (OR 2.19; 95% CI 1.27, 3.77), followed by the third (OR 1.44; 0.96, 2.16) and ultimately by the second trajectory (OR 1.17; 0.86, 1.58). The magnitude of BC risk was greater in postmenopausal women, especially in those with underweight or normal weight. When alcohol consumption was independently examined at each life stage, ≥15 g/day of alcohol consumption in adolescence was strongly associated with BC risk followed by consumption in adulthood. CONCLUSIONS: The greater the alcohol consumption accumulated throughout life, the greater the risk of BC, especially in postmenopausal women. Alcohol consumption during adolescence may particularly influence BC risk.

Incidence of chemotherapy-induced nausea and vomiting associated with docetaxel and cyclophosphamide in early breast cancer patients and aprepitant efficacy as salvage therapy. Results from the Spanish Breast Cancer Group/2009-02 study.

BACKGROUND: Docetaxel-cyclophosphamide (TC) has become a common regimen in moderate-high-risk early breast cancer (EBC), but the incidence of chemotherapy-induced nausea and vomiting (CINV) with this regimen is not well established. This trial investigates the effect of guideline-consistent prophylaxis on CINV related to TC regimen and explores the efficacy of aprepitant among resistant patients. PATIENTS AND METHODS: This prospective multicentre study enrolled 212 chemotherapy-naïve EBC patients receiving T-75 mg/m(2) and C-600 mg/m(2). Antiemetic therapy on the first cycle consisted of dexamethasone for 3 d plus 5-hydroxytryptamine (5-HT3) antagonists on day 1, according to Multinational Association of Supportive Care in Cancer guidelines. The primary end-point was complete response (CR) (no emesis and no need of rescue treatment within the initial 120 h). Patients failing CR on cycle 1 entered in a single-arm study exploring the efficacy of aprepitant on the second cycle. Patients' diaries and Functional Living Index-Emesis (FLIE) questionnaires were collected in cycles 1 and 2. RESULTS: Among the 185 evaluable patients on cycle 1, 161 (87%, 95% confidence interval [CI]: 82.2-91.8) achieved a CR. Twenty-three patients received aprepitant on cycle 2, and 12 reached a CR (52.2%, 95% CI: 31.8-72.6). The absence of CR had a very substantial impact on quality of life on cycles 1 (FLIE before and after: 23.8-38.1, p = 0.0124) and 2 (18.3-42.9, p = 0.0059). CONCLUSIONS: Guideline-consistent antiemetic prophylaxis for the TC regimen is associated with a low incidence of CINV. Aprepitant is effective as secondary prevention of CINV and should be considered as rescue therapy in patients treated with moderate emetogenic chemotherapy.

Oncologists' perceptions of cancer pain management in Spain: the real and the ideal.

AIM: Studies in some countries suggest that cancer pain is often not adequately controlled, but little is known about the situation in Spain. The objective of this study was to identify medical oncologists' perceptions about pain management in their patients. METHODS: Two-round Delphi survey of 24 medical oncologists from 22 large, geographically diverse hospitals in Spain. Physicians rated each of 150 statements on a Likert scale (1=strongly disagree; 5=strongly agree). The mean, standard deviation and frequency of replies in three agreement categories were calculated for each item. Statements allowing comparison of oncologists' perceptions of how pain is managed in routine clinical practice with how it should be managed were grouped together and analyzed. RESULTS: The most notable discrepancies between the real and the ideal occurred in the failure to provide written information or to confirm that patients understand what they are told, the lack of comprehensive and systematic evaluation of pain, and the lack of use of non-pharmacological treatments (NPTs) for cancer pain. CONCLUSIONS: Medical oncologists need to improve their communication skills, providing patients with both written and verbal information about their disease and the plan for pain management. Pain should be evaluated at each patient visit using validated scales, and greater attention should be paid to the possible use of NPTs.

Influence of timing of initiation of adjuvant chemotherapy over survival in breast cancer: a negative outcome study by the Spanish Breast Cancer Research Group (GEICAM).

PURPOSE: This retrospective trial evaluates whether the timing of initiation of the adjuvant chemotherapy has any influence over survival in early-stage breast cancer. PATIENTS AND METHODS: A total of 2782 patients from El Alamo project (from 1990 to 1997; n = 15,400) were selected with stages I-III, surgery and adjuvant chemotherapy. Data were gathered about prognostic factors such as age, tumor size, vessel permeation (vascular or lymphatic), histological grade, and number of involved nodes, hormonal receptor status and administration of hormone therapy. The time interval between surgery and initiation of chemotherapy, and dates of relapse, second primary breast tumor and death were recorded. Patients were assigned in four groups according to the surgery-chemotherapy interval: <3 weeks (group A), 3-6 weeks (group B), 6-9 weeks (group C) and >9 weeks (group D). RESULTS: There were no differences in disease-free survival (DFS), nor in 5-year overall survival (OS), according to the timing of initiation of adjuvant chemotherapy. Cox proportional hazards model was used to adjust analysis for known prognostic factors but the effect of surgery-chemotherapy interval remained non-significant. The variable timing of initiation of adjuvant chemotherapy has also been assessed as a continuous variable and no differences have been detected. CONCLUSION: The optimum time of initiation of adjuvant chemotherapy in early stages of breast cancer is unknown. The delay in the initiation of adjuvant chemotherapy has no influence over survival in the analyzed time intervals. Retrospective analysis like this one with enough statistical power would be necessary to detect differences among groups.

Vinorelbine as a 96-hour continuous infusion in heavily pretreated patients with metastatic breast cancer: a cooperative study by the GEICAM group.

The efficacy of vinorelbine given as a continuous infusion was evaluated in 47 patients with breast cancer who had received previous treatment with first-line, second-line, and third-line chemotherapy including taxanes and/or anthracyclines. For inclusion into the study, patients were required to have histology-proven bi-dimensionally measurable disease. The treatment schedule was a bolus injection of vinorelbine 8 mg/m(2) administered over 5-10 minutes on day 1 followed by vinorelbine 8 mg/m(2) continuous infusion on days 1-4, every 21 days for 6 cycles. On an intent-to-treat basis, a 2% complete response rate and a 17% partial response rate were observed. The median time to progression was 2.4 months (95% CI, 1.83-2.97). Median survival was 7.73 months (95% CI, 4.48-10.98; range, 0.33-55.0 months). Major toxicities included febrile neutropenia in 40 cycles (24%) affecting 24 patients (51%) and 1 toxic death. Other nonhematologic toxicities included stomatitis (13%) and asthenia (13%). We conclude that this treatment shows considerable therapeutic activity, albeit at considerable toxicity costs, even in patients who have had multiple lines of prior chemotherapy. However, the results do not indicate clear advantages compared to the conventional weekly scheme of administration.
