Impact of a supportive care service for cancer outpatients: management and reduction of hospitalizations. Preliminary results of an integrated model of care.

PURPOSE: Supportive care in oncology is a primary need for every oncology department nowadays. In 2012, in our institution, a dedicated supportive care service (SCS) was created in order to deal with any need our on-treatment patients might have (e.g. tumour-related or treatment-related symptoms). We hypothesized that this service had a positive impact on the number of unplanned hospitalizations; to confirm our hypothesis, we decided to review admission data in 2011 and 2012. METHODS: Using our internal software, we compared admission data in 2011 (that is, the year before the dedicated service was created) and 2012 (when such service began, that is April of that year). We also made an evaluation of the costs of these hospitalizations. RESULTS: Despite an increase of the number of patients treated in our day hospital (+6.5 %), the number of unplanned hospital admissions decreased by 3.2 % (from 17.3 to 14.1 %). The number of patients accessing to emergency room went from 66 to 61 % (a reduction of 5 %). The costs of these hospitalizations were reduced by 2.2 %. CONCLUSIONS: The introduction of the dedicated SCS in our oncology department caused a net reduction by 3.2 % of the number of unplanned hospitalizations of on-treatment cancer patients.

VEGF-A polymorphisms predict progression-free survival among advanced castration-resistant prostate cancer patients treated with metronomic cyclophosphamide.

BACKGROUND: No data are available on the pharmacogenetics of metronomic chemotherapy in prostate cancer. The aim of this study was to evaluate the association between VEGF-A sequence variants and prostate-specific antigen (PSA) progression, progression-free survival (PFS) and overall survival (OS), in advanced castration-resistant prostate cancer patients treated with metronomic cyclophosphamide (CTX), celecoxib and dexamethasone. METHODS: Forty-three patients were enrolled, and genomic DNA was extracted. VEGF-A gene SNPs (-2578A/C, -634C/G, +936C/T) were analysed using TaqMan PCR assays. Hardy-Weinberg equilibrium was tested for each SNP, and genetic effects were evaluated by Fisher's exact test. PFS and OS were analysed with GraphPad Prism software, using the product limit method of Kaplan and Meier, and comparing survival curves using both the log-rank test and the Gehan-Wilcoxon test. We used Bonferroni correction to account for multiple testing, and a two-tailed P-value of <0.017 was considered statistically significant. RESULTS: Overall, 20 patients (46%) experienced a reduction in PSA levels from baseline and, among them, 14 (32%) showed a confirmed PSA ≥50% decrease. In non-responders, the -2578CC genotype was more frequent (18.60% vs 2.33% in responders; P=0.0212) whereas the -634CC genotype frequency was 22.73% vs 0% in responders (P=0.0485). With regard to PFS, patients harbouring the -634CC genotype had a median PFS of 2.2 months whereas patients with the genotype -634CG/GG had a median PFS of 6.25 months (P=0.0042). CONCLUSION: The -634CC genotype is significantly associated with a shorter PFS in patients treated with a metronomic CTX schedule.
