The goal of this systematic review was to investigate and compare the treatment effects of systemic chemotherapy (i.e. doxorubicin, gemcitabine, gemcitabine plus docetaxel, or trabectedin) in women with inoperable, locally advanced, recurrent, or metastatic uterine leiomyosarcoma. A 2005 systematic review (searching the literature from 1980 to June 2004) on systemic therapy in advanced uterine sarcoma was used as the basis for this updated review. MEDLINE and EMBASE (from January 2004 to June 2011), the Cochrane Library, some main guideline websites and the American Society of Clinical Oncology and the Connective Tissue Oncology Society annual meeting abstracts were searched. One arm from a randomised controlled trial (RCT), four single-arm phase II trials and one abstract were included in this systematic review. The studies of gemcitabine plus docetaxel have reported numerically longer median overall survival (14.7-17.9 months versus 12.1 months) and numerically higher objective response rates (27-53% versus 25%) than those reported in the study of doxorubicin alone. The combination of gemcitabine plus docetaxel resulted in more toxicity than doxorubicin alone. The available study for single-agent gemcitabine reported a tumour response rate of 21%, which is not superior to the 25% response rate with doxorubicin alone. One abstract (pooling data from two RCTs) failed to show the superiority of gemcitabine plus docetaxel over gemcitabine alone for tumour response rate (23% versus 18%) and progression-free survival (6 versus 4.9 months). To date, there is insufficient evidence to support or refute the use of trabectedin in the target patients. Doxorubicin, gemcitabine, and gemcitabine plus docetaxel are treatment options in women with inoperable, locally advanced, recurrent, or metastatic uterine leiomyosarcoma as first- or second-line therapy. Well-designed and good-quality RCTs are required to investigate the efficacy of chemotherapy and quality of life in target patients with uterine leiomyosarcoma. © 2012 The Royal College of Radiologists.

Purpose This systematic review outlines current evidence regarding the effectiveness of intraspinal techniques for cancer pain and addresses practical implementation issues. Methods A search of electronic databases identified systematic reviews and randomized controlled trials (RCTs) evaluating the effectiveness of intraspinal techniques in the setting of cancer pain. An environmental scan was completed via the internet to identify practice guidelines and resource documents addressing organizational and implementation issues in the delivery of intraspinal analgesia. Elements reviewed included patient selection, contraindications, monitoring, aftercare, follow-up, hospital discharge equipment, health personnel, patient education, and safety. Main results Three systematic reviews, three consensus conferences, and 12 RCTs met the inclusion criteria for evidence of effectiveness. No single systematic review or consensus conference included all relevant RCTs or specifically addressed the use of intraspinal techniques for cancer pain. Six RCTs compared intraspinal techniques alone or combined with other interventions alone or in combination, four compared different intraspinal medications, and two compared different intraspinal techniques. In general, the evidence supported the use of intraspinal techniques for cancer pain management. The two main indications consistently identified were intractable pain not controlled by other conventional medical routes and/or side effects from conventional pain management strategies preventing dose escalation. Reports indicate intraspinal analgesia is equally or more effective than conventional medical management and often associated with fewer side effects. Thirteen resource documents addressed issues surrounding the delivery of intraspinal analgesia and program implementation. Conclusions Intraspinal techniques monitored by an interprofessional health care team should be included as part of a comprehensive cancer pain management program. © Springer-Verlag 2009. Source

Objective: The cost-effectiveness of oxaliplatin in combination with 5-fluorouracil/leucovorin (5FU/LV)-the FOLFOX regimen-was compared with that of 5FU/LV alone as adjuvant therapy for patients with stage III colon cancer, from the perspective of the Cancer Care Ontario New Drug Funding Program. In the mosaic (Multicenter International Study of Oxaliplatin/5-Fluorouracil/Leucovorin in the Adjuvant Treatment of Colon Cancer) trial, the FOLFOX regimen significantly improved disease-free survival. The MOSAIC trial formed the basis of the present analysis. Methodology: Extrapolated patient-level data from the MOSAIC trial were used to model patient outcomes from treatment until death. Utilities were obtained from the literature. Resource utilization data were derived from the MOSAIC trial and supplemented with data from the literature. Unit costs were obtained from the Ontario Ministry of Health and Long-Term Care, the London Health Sciences Centre, and the literature. Results: Lifetime incremental cost-effectiveness ratios for folfox compared with 5FU/LV were CA$14,266 per disease-free year, CA$23,598 per life-year saved, and CA$24,104 per quality adjusted life-year (QALY) gained, discounting costs and outcomes at 5% per annum. These results were stable for a wide range of inputs; only utility values associated with relapse seemed to influence the cost-effectiveness ratios observed. Conclusions: With an incremental cost of CA$24,104 per QALY gained, FOLFOX is a cost-effective adjuvant treatment for stage III colon cancer. Compared with 5FU/LV alone, this regimen offers better clinical outcomes and provides good value for money. Copyright © 2010 Multimed Inc. Source

Observational studies suggest that physical activity after a breast cancer diagnosis is associated with improved cancer outcomes; however, no randomized data are available. Here, we report an exploratory follow-up of cancer outcomes from the Supervised Trial of Aerobic versus Resistance Training (START). METHODS: The START was a Canadian multicenter trial that randomized 242 breast cancer patients between 2003 and 2005 to usual care (n = 82), supervised aerobic (n = 78), or resistance (n = 82) exercise during chemotherapy. The primary end point for this exploratory analysis was disease-free survival (DFS). Secondary end points were overall survival, distant DFS, and recurrence-free interval. The two exercise arms were combined for analysis (n = 160), and selected subgroups were explored. RESULTS: After a median follow-up of 89 months, there were 25/160 (15.6%) DFS events in the exercise groups and 18/82 (22.0%) in the control group. Eight-year DFS was 82.7% for the exercise groups compared with 75.6% for the control group (HR, 0.68; 95% confidence interval (CI), 0.37-1.24; log-rank, P = 0.21). Slightly stronger effects were observed for overall survival (HR, 0.60; 95% CI, 0.27-1.33; log-rank, P = 0.21), distant DFS (HR, 0.62; 95% CI, 0.32-1.19; log-rank, P = 0.15), and recurrence-free interval (HR, 0.58; 95% CI, 0.30-1.11; Gray test, P = 0.095). Subgroup analyses suggested potentially stronger exercise effects on DFS for women who were overweight/obese (HR, 0.59; 95% CI, 0.27-1.27), had stage II/III cancer (HR, 0.61; 95% CI, 0.31-1.20), estrogen receptor-positive tumors (HR, 0.58; 95% CI, 0.26-1.29), human epidermal growth factor receptor 2-positive tumors (HR, 0.21; 95% CI, 0.04-1.02), received taxane-based chemotherapies (HR, 0.46; 95% CI, 0.19-1.15), and â‰1 85% of their planned chemotherapy (HR, 0.50; 95% CI, 0.25-1.01). CONCLUSIONS: This exploratory follow-up of the START provides the first randomized data to suggest that adding exercise to standard chemotherapy may improve breast cancer outcomes. A definitive phase III trial is warranted. © 2014 by the American College of Sports Medicine. Source

Clinical Journal of Pain | Year: 2011

Objectives: Pain is one of the most prevalent symptoms in patients with advanced cancer and, according to anecdotal reports, perhaps the most feared. Surprisingly, fear of pain has been the subject of little research within cancer care. The literature on chronic noncancer pain, however, suggests that fear of pain contributes to limitations in function in populations with diverse chronic illness. Little is known about the extent to which such findings might generalize from patients with chronic noncancer pain to those with chronic cancer pain. Therefore, this research examined the extent to which fear of pain is associated with limitations in function in patients with advanced cancer and also compared patients with chronic cancer and noncancer pain. Methods: We recruited 117 patients with advanced cancer who received a referral for pain management and 118 patients with a primary complaint of chronic noncancer pain. Participants completed self-report questionnaires. Results: Findings revealed similarities between the groups for fear of pain and limitations in function, but they differed on level of depression and pain severity (patients with noncancer pain were more depressed and reported higher pain severity). Fear of pain independently predicted limitations in function in both groups controlling for demographic variables and pain severity. When depression and physical symptoms were controlled, fear of pain predicted limitations in function only in patients with advanced cancer. Discussion: The findings emphasize the importance of psychological dimensions of pain in patients with advanced cancer, as well as the similarities and differences between the 2 groups of patients suffering from chronic pain. © 2011 by Lippincott Williams & Wilkins.
