Positive and cost-effectiveness effect of spa therapy on the resumption of occupational and non-occupational activities in women in breast cancer remission: a French multicentre randomised controlled trial.

PURPOSE OF THE RESEARCH: The main aim was to assess the effects of a spa treatment on the resumption of occupational and non-occupational activities and the abilities of women in breast cancer remission. A cost-effectiveness analysis (CEA) was also performed. METHODS AND SAMPLE: A multicentre randomised controlled trial was carried out between 2008 and 2010 in the University Hospital of Auvergne and two private hospitals in Clermont-Ferrand, France. Eligible patients were women in complete breast cancer remission without contraindication for physical activities or cognitive disorders and a body mass index between 18.5 and 40 kg/m(2). The intervention group underwent spa treatment combined with consultation with dietician whereas the control underwent consultations with the dietician only. Of the 181 patients randomised, 92 and 89 were included in the intervention and the control groups, respectively. The CEA involved 90 patients, 42 from the intervention group and 48 from the control group. KEY RESULTS: The main results showed a higher rate of resumption of occupational activities in the intervention group (p = 0.0025) and a positive effect of the intervention on the women's ability to perform occupational activities 12 months after the beginning of the study (p = 0.0014), and on their ability to perform family activities (p = 0.033). The stay in a thermal centre was cost-effective at 12 months. CONCLUSIONS: Spa treatment is a cost-effective strategy to improve resumption of occupational and non-occupational activities and the abilities of women in breast cancer remission.

Cisplatin pharmacokinetics in nontumoral pig liver treated with intravenous or transarterial hepatic chemoembolization.

PURPOSE: To evaluate cisplatin (CDDP) pharmacokinetics after its intravenous (IV) or intrahepatic arterial administration (IHA) in healthy pigs with or without embolization by absorbable gelatine. MATERIAL AND METHODS: We analysed plasmatic and hepatic drug concentration in four groups of six mini-pigs each according to the modality of administration of CDDP (1 mg/kg): IV, IHA, IHA with partial embolization using absorbable gelatine (IHA-Pe), and IHA with complete embolization (IHA-Te). Unbounded plasmatic and hepatic platinum concentrations were measured. Concentration and pharmacokinetics parameters were compared using analysis of variance. RESULTS: For all groups, there was a rapid and biexponential decrease in free platinum concentration. Plasmatic terminal half-life (T(1/2)) was significantly decreased after embolization at 191, 178, 42, and 41 min after IV, IHA, IHA-Pe, and IHA-Te administration, respectively. Maximal plasmatic concentration and systemic exposure to CDDP (AUC(24)) values were significantly decreased after embolization (C(max) p = 0.0075; AUC(24) p = 0.0053). Hepatic CDDP concentration rapidly peaked and then decreased progressively. After 24 h, the residual concentration represented 45, 47, 60, and 63 % of C(max), respectively, after IV, IHA, IHA-Pe, and IHA-Te. Hepatic T(1/2) and AUC(∞) values were increased after embolization, but the differences were not statistically significant. CONCLUSION: This preliminary study confirms the feasibility of a pig model to study systemic and hepatic CDDP pharmacokinetics. Systemic exposure is lower after embolization, which could minimize systemic toxicity. Hepatic T(1/2) elimination and hepatic exposition values are increased with IHA compared with IV administration.
