The treatment of patients with recurrent glioblastoma remains a major oncologic problem, with median survival after progression of 7-9 months. To determine the maximum tolerated dose and dose-limiting toxicity (DLT), the combination of dasatinib and cyclonexyl-chloroethyl-nitrosourea (CCNU) was investigated in this setting. The study was designed as multicenter, randomized phase II trial, preceded by a lead-in safety phase. The safety component reported here, which also investigated pharmacokinetics and preliminary clinical activity, required expansion and is therefore considered a phase I part to establish a recommended dosing regimen of the combination of CCNU (90-110 mg/m2) and dasatinib (100-200 mg daily). Overall, 28 patients were screened, and 26 patients were enrolled. Five dose levels were explored. DLTs, mainly myelosuppression, occurred in 10 patients. Grade 3 or 4 neutropenia was recorded in 7 patients (26.9) and thrombocytopenia in 11 patients (42.3). No significant effect of CCNU coadministration on dasatinib pharmacokinetics was found. Median progression-free survival (PFS) was 1.35 months (95 confidence interval: 1.2-1.4) and 6-month PFS was 7.7. In this phase I study of recurrent glioblastoma patients, the combination of CCNU and dasatinib showed significant hematological toxicities and led to suboptimal exposure to both agents. © 2012 The Author(s).

Supportive Care in Cancer | Year: 2013
Purpose: Assessment of health-related quality of life (HRQOL) is critical to effective delivery of palliative care in patients with advanced cancer. The current study analyzes relationships between baseline social determinants of health and medical factors, and self-reported HRQOL in patients with bone metastases receiving palliative radiotherapy. Methods and materials: Advanced cancer patients referred for radiotherapy treatment of bone metastases completed the EORTC QLQ-C30 questionnaire in multiple outpatient clinics internationally. Demographics and social determinants were collected as baseline information. Univariate and Bonferroni-adjusted multivariate linear regression analyses were used to detect significant correlations between baseline determinants and different HRQOL domains. Results: Karnofsky Performance Status (KPS) was correlated with better physical (p = 0.0002), role (p < 0.0001), emotional (p < 0.0001), and social (p < 0.0001) functioning, and global health scores (p = 0.0015) and predicted lower symptom scores for fatigue (p < 0.0001), pain (p < 0.0001), appetite loss (p < 0.0001), and constipation (p < 0.0001). Increased age was predictive of better social functioning (p < 0.0001) and less insomnia (p = 0.0036), higher education correlated with better global health status (p = 0.0043), and patients who were employed or retired had improved physical functioning (p = 0.0004 and p = 0.0030, respectively) and less financial challenges compared to patients who were unemployed (p = 0.0005). Conclusions: Baseline KPS had the greatest influence on EORTC QLQ-C30 domain scores. Age, education level, and employment status had significant impacts, although on fewer domains. Further studies that investigate baseline determinants are worthwhile to clarify relationships in order to care for patients more effectively at the end of life. © 2013 Springer-Verlag Berlin Heidelberg.

Background: The effect of adjuvant chemotherapy on survival for resected soft-tissue sarcoma remains unknown. We investigated the effect of intensive adjuvant chemotherapy on survival in patients after resection of high-risk soft-tissue sarcomas. Methods: In this multicentre randomised trial, patients with macroscopically resected, Trojani grade II-III soft-tissue sarcomas at any site, no metastases, performance status lower than 2 and aged between 16 and 70 years were eligible within 4 weeks of definitive surgery. Patients were randomly assigned to receive adjuvant chemotherapy or no chemotherapy (control group). Randomisation was done with a minimisation technique, stratified by hospital, site of primary tumour, tumour size, planned radiotherapy, and isolated limb perfusion therapy. Chemotherapy consisted of five cycles of doxorubicin 75 mg/m2, ifosfamide 5 g/m2, and lenograstim every 3 weeks. Patients in both groups received radiotherapy if the resection was marginal or the tumour recurrent. The primary endpoint was overall survival and analyses were done by intention to treat. The final results are presented. This trial is registered with ClinicalTrials.gov, NCT00002641. Findings: Between February, 1995, and December, 2003, 351 patients were randomly assigned to the adjuvant chemotherapy group (175 patients) or to the control group (176). 258 (73%) of 351 patients received radiotherapy, 129 in each group. Overall survival did not differ significantly between groups (hazard ratio [HR] 0·94 [95% CI 0·68-1·31], p=0·72) nor did relapse-free survival (HR 0·91 [0·67-1·22], p=0·51). 5-year overall survival rate was 66·5% (58·8-73·0) in the chemotherapy group and 67·8% (60·3-74·2) in the control group. Chemotherapy was well tolerated, with 130 (80%) of 163 patients who started it completing all five cycles. 16 (10%) patients had grade 3 or 4 fever or infection, but no deaths due to toxic effects were recorded. Interpretation: Adjuvant chemotherapy with doxorubicin and ifosfamide in resected soft-tissue sarcoma showed no benefit in relapse-free survival or overall survival. Future studies should focus on patients with larger, grade III, and extremity sarcomas. Funding: European Organisation for Research and Treatment of Cancer, Rhone-Poulenc-Rorer. © 2012 Elsevier Ltd.

Purpose: This phase III trial compared adjuvant whole-brain radiotherapy (WBRT) with observation after either surgery or radiosurgery of a limited number of brain metastases in patients with stable solid tumors. Here, we report the health-related quality-of-life (HRQOL) results. Patients and Methods: HRQOL was a secondary end point in the trial. HRQOL was assessed at baseline, at 8 weeks, and then every 3 months for 3 years with the European Organisation for Research and Treatment of Cancer (EORTC) Quality of Life Questionnaire C30 and Brain Cancer Module. The following six primary HRQOL scales were considered: global health status; physical, cognitive, role, and emotional functioning; and fatigue. Statistical significance required P < .05, and clinical relevance required a ≥ 10-point difference. Results: Compliance was 88.3% at baseline and dropped to 45.0% at 1 year; thus, only the first year was analyzed. Overall, patients in the observation only arm reported better HRQOL scores than did patients who received WBRT. The differences were statistically significant and clinically relevant mostly during the early follow-up period (for global health status at 9 months, physical functioning at 8 weeks, cognitive functioning at 12 months, and fatigue at 8 weeks). Exploratory analysis of all other HRQOL scales suggested worse scores for the WBRT group, but none was clinically relevant. Conclusion: This study shows that adjuvant WBRT after surgery or radiosurgery of a limited number of brain metastases from solid tumors may negatively impact some aspects of HRQOL, even if these effects are transitory. Consequently, observation with close monitoring with magnetic resonance imaging (as done in the EORTC trial) is not detrimental for HRQOL. © 2012 by American Society of Clinical Oncology. Source
