OBJECTIVE: Intraperitoneal (IP) chemotherapy in women with optimally debulked stage III ovarian cancer has been reported to prolong overall survival, but has not been widely adopted due to concerns about its toxicity, inconvenience and acceptability to patients. The purposes of this study were to determine the regimen's feasibility, adverse events, catheter-related complications, progression-free survival, health-related quality of life (HRQL), and patients' preferences for IP versus intravenous (IV) chemotherapy. METHODS: We conducted a single arm, multi-center study of IP chemotherapy with IV paclitaxel 135 mg/m2 (D1) over 3 hours, IP cisplatin 75 mg/m2 (D2), and IP paclitaxel 60 mg/m2 (D8) for 6 cycles in women with optimally debulked stage III ovarian or related cancers. RESULTS: Thirty-eight eligible patients were recruited from 12 sites between July 2007 and December 2009. Seventy-one percent (n=27) completed at least 4 cycles and 63% (n=24) completed all 6 cycles. Grade 3 or 4 adverse events included nausea (n=2), vomiting (n=2), abdominal pain (n=2), and diarrhea (n=1), but not febrile neutropenia, neurotoxicity, or nephropathy. There were no treatment-related deaths. Catheter-related complications were the most frequent cause of early discontinuation of treatment (16 patients, 21%). Apart from neurotoxicity HRQL which worsened over time, HRQL was stable or improved with time. Most patients (> or =50%) judged moderate benefits (e.g., an extra 6 months survival time or a 5% improvement in survival rates) necessary to make IP chemotherapy worthwhile. CONCLUSION: IP chemotherapy was feasible, tolerable, and most participants considered moderate survival benefits sufficient to warrant the adverse effects and inconvenience.

OBJECTIVE: Prior functional magnetic resonance imaging (fMRI) work has revealed that children/adolescents with disruptive behavior disorders (DBDs) show dysfunctional reward/non-reward processing of non-social reinforcements in the context of instrumental learning tasks. Neural responsiveness to social reinforcements during instrumental learning, despite the importance of this for socialization, has not yet been previously investigated. METHODS: Twenty-nine healthy children/adolescents and 19 children/adolescents with DBDs performed the fMRI social/non-social reinforcement learning task. Participants responded to random fractal image stimuli and received social and non-social rewards/non-rewards according to their accuracy. RESULTS: Children/adolescents with DBDs showed significantly reduced responses within the caudate and posterior cingulate cortex (PCC) to non-social (financial) rewards and social non-rewards (the distress of others). Connectivity analyses revealed that children/adolescents with DBDs have decreased positive functional connectivity between the ventral striatum (VST) and the ventromedial prefrontal cortex (vmPFC) seeds and the lateral frontal cortex in response to reward relative to non-reward, irrespective of its sociality. In addition, they showed decreased positive connectivity between the vmPFC seed and the amygdala in response to non-reward relative to reward. CONCLUSION: These data indicate compromised reinforcement processing of both non-social rewards and social non-rewards in children/adolescents with DBDs within core regions for instrumental learning and reinforcement-based decision-making (caudate and PCC). In addition, children/adolescents with DBDs show dysfunctional interactions between the VST, vmPFC, and lateral frontal cortex in response to rewarded instrumental actions potentially reflecting disruptions in attention to rewarded stimuli.
