RESUMO
PURPOSE: Adjuvant treatment decisions in early breast cancer (eBC) have traditionally been driven by risk stratification based on clinical and pathological risk factors. The 21-gene Oncotype DX® assay has been validated as a predictive test for benefit from adjuvant chemotherapy (CT), hence assessing its impact in clinical decisions is of high interest. The objective of this study was to estimate the rate of adjuvant treatment decision modification impacted by the Recurrence Score® result, and the consequent budget impact. METHODS: The study was a multicentre, prospective, real-life experience in Lombardy (Italy) including consecutive patients with T1-T3, N0-N1a, and ER+/HER2-eBC with clinical-pathologic "intermediate risk" of relapse. The change in treatment recommendations was assessed before and after availability of Recurrence Score result. A budget model evaluated the implications of 21-gene testing in the study population. RESULTS: The overall proportion of CT recommendations was reduced from 24.6% to 15.2% after 21-gene testing, with a major impact in patients initially considered for CT plus hormone therapy (CHT). In these patients, the total budget was reduced, leading to a net saving of -81,017. The greater the physician propensity to prescribe CHT, the higher the potential savings for the health system from sparing CT in most tested patients. CONCLUSIONS: Our real-life experience suggests that all intermediate-risk ER+/HER2-eBC patients who are initially deemed candidates for CHT should be tested with the 21-gene test. The potential to spare CT in at least half of them offers relevant advantages for patients and national health services.

AIMS AND BACKGROUND: Sequential docetaxel and gemcitabine following initial docetaxel plus epirubicin or vinorelbine association could be worthwhile as first-line treatment of metastatic breast cancer. METHODS: Fifty-eight patients entered a phase II study that included two sequential phases. In the first phase, 36 and 22 patients previously unexposed or exposed to adjuvant anthracyclines received the association of docetaxel (75 mg/m2, day 1) with epirubicin (75 mg/m2, day 1) or vinorelbine (20 mg/m2, days 1 and 5), respectively, every 21 days for 4 courses. In the second phase, patients who had a response (R) or stable disease (SD) received docetaxel (35 mg/m2) and gemcitabine (800 mg/m2) on days 1, 8 and 15 every 28 days for 4 courses. RESULTS: In the first phase, grade > or = III neutropenia occurred in 51% and 37% of patients during docetaxel-epirubicin and docetaxel-vinorelbine, respectively. In the second phase, it occurred in the 27% and 15% of patients initially treated with docetaxel-epirubicin and docetaxel-vinorelbine, respectively. On an intention to treat basis, the complete (CR) + partial response (PR) rate to the first phase was 71%, and 22% of patients had SD, without a significant difference between the docetaxel-epirubicin and docetaxel-vinorelbine arms. After the second phase, the CR + PR rate was 65%, and 14% of patients had SD. Median time to progression and survival were 12.1 and 22.0 months, respectively, without a significant difference between patients initially treated with docetaxel-epirubicin and docetaxel-vinorelbine. CONCLUSIONS: Following an initial docetaxel-based treatment, weekly docetaxel and gemcitabine maintains high percentages of R and SD, with improved toxicity. Survival was similar in patients previously untreated and treated with adjuvant anthracyclines.

AIMS AND BACKGROUND: Granulocyte colony-stimulating factors are widely used to reduce myelotoxicity of chemotherapy and to allow its regular administration. National and international guidelines regulate their use. The aim of the study was to evaluate the use of pegfilgrastim and filgrastim/lenograstim in clinical practice, adherence to ASCO and ESMO guidelines, chemotherapy-related complications and adverse reactions. MATERIALS AND METHODS: Data from 645 consecutive patients and 3,150 chemotherapy administrations, receiving granulocyte colony-stimulating factors, as primary/secondary prophylaxis or therapeutic use, for the first time during a line of chemotherapy, were recorded from 08/2008 to 08/2011, in 10 Lombardy Italian cancer centers. Patients and chemotherapy administrations data were examined in a multiple logistic regression analysis model. RESULTS: Adherence to guidelines: primary prophylaxis, pegfilgrastim and filgrastim/ lenograstim 66%/47% (P = 0.002); secondary prophylaxis, 19.0%/26.8%; but 56.8%/ 53.6% including patients at high risk of febrile neutropenia with grade 3-4 neutropenia. Correct timing start (administration 24-72 h after chemotherapy): pegfilgrastim and filgrastim/lenograstim, 93.2%/61.5% (P <0.0001). CONCLUSIONS: Results suggest the more correct administration of pegfilgrastim as primary prophylaxis and timing start, compared to filgrastim/lenograstim. In secondary prophylaxis, the use of granulocyte colony-stimulating factors is extended beyond guideline recommendations to support patients at high risk of febrile neutropenia and to guarantee dose intensity. These outcomes suggest both the need of educational activities and the development of predictive tools to better define high risk patients and the use of granulocyte colony-stimulating factors.

AIM OF THE STUDY: at present, there is very little data available about the impact of anemia on elderly cancer patient's quality of life (QoL). Most of the acquired knowledge has been derived from small studies selected for primary site cancer. This observational study investigates the association between hemoglobin (Hb) level and comprehensive geriatric assessment variables: Cancer Linear Analog Scale (CLAS), Activities of Daily Living (ADL), Mini-Mental State Examination (MMSE) in elderly cancer patients undergoing chemotherapy (CT). METHODS: we enrolled 586 elderly cancer patients undergoing CT who were evaluated at baseline and every 3-4 weeks for at least 12 weeks. The correlation between Hb level changes and the examined index changes were performed using Pearson correlation analysis and a multivariate analysis was performed using a logistic regression model. RESULTS: both univariate and multivariate analyses at baseline showed that Hb values are related to ECOG performance status (PS), stage of disease and self-reported QoL. Hb level variation significantly correlated with CLAS and ADL changes measured at baseline and after 12 weeks. This correlation is highly significant in patients with Hb< 11g/dl. Multivariate analysis showed that Hb change of at least 1g/dl was the only independent predictor of a better quality of life, when assessed by using the CLAS and ADL questionnaire (p<0.05). Moreover the median time of hospitalisation was found to be significantly lower in patients showing higher Hb level (Hb ≥ 11g/dl) (p=0.037). CONCLUSIONS: the findings of this study seem to provide adequate support for the correlation between anemia and elderly cancer patient's QoL. Interestingly, we reported an association between anemia and the length of hospitalisation in this setting of patients. However, the above results do need to be confirmed by further prospective trials.

Infections in cancer patients after implantation of a central venous device (CVD) are not infrequent and are potentially serious. The possibility of limiting this complication with antithrombotic drugs is still debated. For this observational study, we recorded the routine management of CVD in cancer patients in 18 oncology centers in Lombardy (northern Italy), assessing the effect of antithrombotic prophylaxis on catheter-related infections. Out of 1410 patients enrolled, 451 received antithrombotic prophylaxis continuously after implantation of the central line. During a median follow-up of 30 months, 57 catheter-related infections were reported in the 1390 patients seen at least once at follow-up visits (4.1% of the whole series), giving an overall incidence of 0.10 infections per 1000 catheter days. This complication was significantly more frequent among patients with an indwelling central venous catheter, or peripherally inserted catheter, than among those with a port device, and the group not given antithrombotic prophylaxis had 0.14 infective complications/1000 CVD days compared with 0.05/1000 CVD days (odds ratio 2.4; 95% confidence interval 1.7-5.0) for those treated. Antithrombotic prophylaxis protected against infections at the catheter exit site and track but not against systemic infections. Confirming earlier evidence, this study found a reduction in catheter-related infections in patients given antithrombotic prophylaxis. However, this reduction, reflecting local infections, seems unlikely to be one of the mechanisms explaining the lower mortality among our patients treated with anticoagulants.
