Pain and analgesic use associated with skeletal-related events in patients with advanced cancer and bone metastases

PURPOSE: Bone metastases secondary to solid tumors increase the risk of skeletal-related events (SREs), including the occurrence of pathological fracture (PF), radiation to bone (RB), surgery to bone (SB), and spinal cord compression (SCC). The aim of this study was to evaluate the impact of SREs on patients' pain, analgesic use, and pain interference with daily functioning. METHODS: Data were combined from patients with solid tumors and bone metastases who received denosumab or zoledronic acid across three identically designed phase 3 trials (N = 5543). Pain severity (worst pain) and pain interference were assessed using the Brief Pain Inventory at baseline and each monthly visit. Analgesic use was quantified using the Analgesic Quantification Algorithm. RESULTS: The proportion of patients with moderate/severe pain and strong opioid use generally increased in the 6 months preceding an SRE and remained elevated, while they remained relatively consistent over time in patients without an SRE. Regression analysis indicated that all SRE types were significantly associated with an increased risk of progression to moderate/severe pain and strong opioid use. PF, RB, and SCC were associated with significantly greater risk of pain interference overall. Results were similar for pain interference with emotional well-being. All SRE types were associated with significantly greater risk of pain interference with physical function. CONCLUSIONS: SREs are associated with increased pain and analgesic use in patients with bone metastases. Treatments that prevent SREs may decrease pain and the need for opioid analgesics and reduce the impact of pain on daily functioning

Patient attitudes towards chemotherapy and survival: A prospective observational study in advanced non-small cell lung cancer

WOS: 000272370400017PubMed ID: 19264374This multicenter, non-interventional, prospective, observational study aimed to determine whether patients' attitude to chemotherapy is an independent prognostic factor for survival in patients with advanced non-small cell lung cancer (NSCLC) who are treated with gemcitabine-platinum. Chemonaive patients (n = 1895) with stage IIIB or IV NSCLC not amenable to curative surgery or radiotherapy were treated with a combination of gemcitabine plus cisplatin/carboplatin and followed for a maximum of 18 months. Patients' attitude to treatment was measured on a 5-point scale and responses were used to assign patients to one of the three need categories: A, maximum extension of survival with the acceptance of high toxicity (60.0% of patients); B, maximum extension of survival only if coupled with normal lifestyle (26.1%); C, relief of symptoms (13.8%). Median survival varied significantly among the need categories (A = 13.00 months, B = 15.70 months, C = 15.33 months; log-rank test P=0.0415). Patient attitude to treatment (need categories) was not a significant prognostic factor for survival after adjusting for known prognostic factors (P=0.0503). After adjusting for baseline differences, patients in this study had a significantly lower risk of death than patients in three randomized trials (hazard ratio 0.879; 95% confidence interval: 0.775, 0.998; P=0.0458). In conclusion, in this observational study, patient attitude to chemotherapy was not an independent prognostic factor of survival. (C) 2009 Elsevier Ireland Ltd.

Pain and health-related quality of life in patients with advanced solid tumours and bone metastases: integrated results from three randomized, double-blind studies of denosumab and zoledronic acid

PURPOSE: This analysis evaluated patient-reported outcomes and analgesic use in patients with bone metastases from solid tumours across three comparative studies of denosumab and zoledronic acid. METHODS: Pooled data were analysed from three identically designed double-blind phase III studies comparing subcutaneous denosumab 120 mg with intravenous zoledronic acid 4 mg monthly in patients with bone metastases from breast cancer (n = 2,046), castration-resistant prostate cancer (n = 1,901) or other solid tumours (n = 1,597). Pain severity, pain interference, health-related quality of life and analgesic use were quantified. RESULTS: At baseline, approximately half of patients had no/mild pain (53 % [1,386/2,620] denosumab; 50 % [1,297/2,578] zoledronic acid). Denosumab delayed onset of moderate/severe pain by 1.8 months (median, 6.5 vs 4.7 months; hazard ratio, 0.83; 95 % CI, 0.76-0.92; p < 0.001; 17 % risk reduction) and clinically meaningful increases in overall pain interference by 2.6 months (median, 10.3 vs 7.7 months; hazard ratio, 0.83; 95 % CI, 0.75-0.92; p < 0.001; 17 % risk reduction) compared with zoledronic acid. Strong opioid use and worsening of health-related quality of life were less common with denosumab. CONCLUSIONS: Across three large studies of patients with advanced solid tumours and bone metastases, denosumab prevented progression of pain severity and pain interference more effectively than zoledronic acid
