Methods to Standardize a Multicenter Acupuncture Trial Protocol to Reduce Aromatase Inhibitor-related Joint Symptoms in Breast Cancer Patients
AbstractRobust methods are needed to efficiently conduct large, multisite, randomized, controlled clinical trials of acupuncture protocols. The Southwest Oncology Group (SWOG) S1200 trial is a randomized, controlled (i.e., sham-controlled and waitlist-controlled) trial of a standardized acupuncture protocol for treating aromatase inhibitor (AI)-associated arthralgias in early-stage breast cancer patients (n = 228). The primary objective of this study was to determine whether true acupuncture administered twice weekly for 6 weeks, as compared to sham acupuncture or a waitlist control, reduced AI-associated joint pain at 6 weeks as assessed by patient reports. The study was conducted at 11 institutions across the United States. The true acupuncture protocol was developed using a consensus-based process. The true acupuncture and the sham acupuncture protocols each consisted of 12 sessions administered for 6 weeks, followed by one weekly session for 6 weeks. The true acupuncture protocol used standardized protocol points, and the standardized acupoints were tailored to a patient's joint symptoms. The similarly standardized sham acupuncture protocol utilized superficial needling of nonacupoints. Standardized methods were developed to train and monitor acupuncturists and included online and in-person training, study manuals, monthly phone calls, and remote quality assurance monitoring throughout the study period. The research staff similarly received online and in-person training and monthly phone calls

Overall Survival with Fulvestrant plus Anastrozole in Metastatic Breast Cancer
BACKGROUND We previously reported prolonged progression-free survival and marginally prolonged overall survival among postmenopausal patients with hormone receptor-positive metastatic breast cancer who had been randomly assigned to receive the aromatase inhibitor anastrozole plus the selective estrogen-receptor down-regulator fulvestrant, as compared with anastrozole alone, as first-line therapy. We now report final survival outcomes. METHODS We randomly assigned patients to receive either anastrozole or fulvestrant plus anastrozole. Randomization was stratified according to adjuvant tamoxifen use. Analysis of survival was performed by means of two-sided stratified log-rank tests and Cox regression. Efficacy and safety were compared between the two groups, both overall and in subgroups. RESULTS Of 707 patients who had undergone randomization, 694 had data available for analysis. The combination-therapy group had 247 deaths among 349 women (71%) and a median overall survival of 49.8 months, as compared with 261 deaths among 345 women (76%) and a median overall survival of 42.0 months in the anastrozole-alone group, a significant difference (hazard ratio for death, 0.82; 95% confidence interval (CIS, 0.69 to 0.98; P=0.03 by the log-rank test). In a subgroup analysis of the two strata, overall survival among women who had not received tamoxifen previously was longer with the combination therapy than with anastrozole alone (median, 52.2 months and 40.3 months, respectively; hazard ratio, 0.73; 95% CI, 0.58 to 0.92); among women who had received tamoxifen previously, overall survival was similar in the two groups (median, 48.2 months and 43.5 months, respectively; hazard ratio, 0.97; 95% CI, 0.74 to 1.27) (P=0.09 for interaction). The incidence of long-term toxic effects of grade 3 to 5 was similar in the two groups. Approximately 45% of the patients in the anastrozole-alone group crossed over to receive fulvestrant. CONCLUSIONS The addition of fulvestrant to anastrozole was associated with increased long-term survival as compared with anastrozole alone, despite substantial crossover to fulvestrant after progression during therapy with anastrozole alone. The results suggest that the benefit was particularly notable in patients without previous exposure to adjuvant endocrine therapy.National Cancer Institute; AstraZeneca6 month embargo; published 28 March 2019.This item from the UA Faculty Publications collection is made available by the University of Arizona with support from the University of Arizona Libraries.

Randomized Multicenter Placebo-Controlled Trial of Omega-3 Fatty Acids for the Control of Aromatase Inhibitor-Induced Musculoskeletal Pain: SWOG S0927.
PurposeMusculoskeletal symptoms are the most common adverse effects of aromatase inhibitors (AIs) and can result in decreased quality of life and discontinuation of therapy. Omega-3 fatty acids (O3-FAs) can be effective in decreasing arthralgia resulting from rheumatologic conditions and reducing serum triglycerides.Patients and methodsWomen with early-stage breast cancer receiving an AI who had a worst joint pain/stiffness score â„ 5 of 10 using the Brief Pain Inventory-Short Form (BPI-SF) were randomly assigned to receive either O3-FAs 3.3 g or placebo (soybean/corn oil) daily for 24 weeks. Clinically significant change was defined as â„ 2-point drop from baseline. Patients also completed quality-of-life (Functional Assessment of Cancer Therapy-Endocrine Symptoms) and additional pain/stiffness assessments at baseline and weeks 6, 12, and 24. Serial fasting blood was collected for lipid analysis.ResultsAmong 262 patients registered, 249 were evaluable, with 122 women in the O3-FA arm and 127 in the placebo arm. Compared with baseline, the mean observed BPI-SF score decreased by 1.74 points at 12 weeks and 2.22 points at 24 weeks with O3-FAs and by 1.49 and 1.81 points, respectively, with placebo. In a linear regression adjusting for the baseline score, osteoarthritis, and taxane use, adjusted 12-week BPI-SF scores did not differ by arm (P = .58). Triglyceride levels decreased in patients receiving O3-FA treatment and remained the same for those receiving placebo (P = .01). No between-group differences were seen for HDL, LDL, or C-reactive protein.ConclusionWe found a substantial (> 50%) and sustained improvement in AI arthralgia for both O3-FAs and placebo but found no meaningful difference between the groups
