Project description:Almost one-half of aromatase inhibitor (AI)-treated breast cancer patients experience AI-associated musculoskeletal symptoms (AIMSS); 20%-30% discontinue treatment because of severe symptoms. We hypothesized that we could identify predictors of pain reduction in AIMSS intervention trials by combining data from previously conducted trials. We pooled patient-level data from 3 randomized trials testing interventions (omega-3 fatty acids, acupuncture, and duloxetine) for AIMSS that had similar eligibility criteria and the same patient-reported outcome measures. Only patients with a baseline Brief Pain Inventory average pain score of at least 4 of 10 were included. The primary outcome examined was 2-point reduction in average pain from baseline to week 12. Variable cut-point selection and logistic regression were used. Risk models were built by summing the number of factors statistically significantly associated with pain reduction. Analyses were stratified by study and adjusted for treatment arm. For the 583 analyzed patients, the 4 factors statistically significantly associated with pain reduction were Functional Assessment of Cancer Therapy Functional Well-Being greater than 24 and Physical Well-Being greater than 14 (higher scores reflect better function), and Western Ontario and McMaster Universities Osteoarthritis Index less than 50 and Modified Score for the Assessment and Quantification of Chronic Rheumatoid Affections of the Hands less than 33 (lower scores reflect less pain). Patients with all 4 factors were greater than 6 times more likely to experience at least a 2-point pain reduction (odds ratio = 6.37, 95% confidence interval = 2.31 to 17.53, 2-sided P < .001); similar results were found for secondary 30% and 50% pain reduction endpoints. Patients with AIMSS who have lower symptom and functional distress at study entry on AIMSS intervention trials are more likely to experience meaningful pain reduction. Baseline symptom and functional status should be considered as stratification factors in future interventional trials.

Project description:Treatment with aromatase inhibitors (AIs) is fundamental in women with hormone receptor-positive breast cancer in the adjuvant as well as the metastatic setting. Even though it is considered to be a well-tolerated therapy, aromatase inhibitor-associated musculoskeletal syndrome (AIMSS) is the most common adverse event encountered by breast cancer patients. CDK4/6 inhibitors have emerged as a new treatment strategy in metastatic hormone receptor-positive breast cancer. However, the impact of CDK4/6 inhibitors on musculoskeletal symptoms caused by AIs is not well-defined. This systematic review aims to identify the frequency of joint symptoms induced by treatment with AIs and CDK4/6 inhibitors in the metastatic setting. Eligible articles were identified by a search of existing literature for the period 2005/01/01-2021/01/01; The algorithm consisted of a predefined combination of the following keywords "breast", "cancer", "aromatase inhibitors", "CDK4/6", "phase III". This study was performed in accordance with PRISMA guidelines. All randomized controlled Phase III trials (RCTs) evaluating the administration of third-generation aromatase inhibitors (AIs) and CDK4/6 inhibitors in postmenopausal women in the metastatic setting were considered eligible for this review. Overall, 16 randomized control trials (RCTs) were retrieved, of which nine studies explored the administration of AIs in the metastatic setting and seven studies investigated the combination of CDK4/6 inhibitors and AIs. Arthralgia was reported in 1-47% of patients treated with AIs and 5.8-33.3% of patients treated with CDK4/6 inhibitors. Myalgias occurred in 2-23.7% of patients receiving AIs compared with 4.8-11.9% of patients treated with CDK4/6 inhibitors. The incidence of back pain was 7-32.9% vs. 2.9-8.5% in postmenopausal women with metastatic disease treated with AIs and CDK4/6 inhibitors, respectively. Bone pain was reported in 7-32.9% of postmenopausal women treated with AIs and 2.9-8.5% of women treated with CDK4/6 inhibitors. AI treatment-induced musculoskeletal syndrome is an adverse event affecting over one-third (20-47%) of postmenopausal patients treated with AIs that often leads to treatment discontinuation. Data from RCTs provide evidence that the incidence of musculoskeletal symptoms is relatively decreased upon CDK4/6 inhibitor administration. CDK4/6 inhibitors may provide a protective role against AIMSS development.

Project description:The goal of the experiment is untargeted metabolomic and shotgun lipidomic profiling of serum samples collected from 50 patients before patients initiated therapy with an aromatase inhibitor and again after 3 months of aromatase inhibitor therapy. Half of the patients discontinued treatment within 6 months because of development of arthralgias during therapy and half remained on therapy for at least 24 months without development of significant arthralgias. We plan to analyse effects of AI therapy on metabolomic and lipidomic profiles, and to investigate associations between changes in profiles and development of symptoms.

Project description:To identify the genes which have relation to aromatase-inhibitor-resistance, we compared the gene expression of aromatase-inhibitor-resistant cell, A3, with that of parent cell line, T-47D.

Project description:An approximately 60% of chronic myeloid leukemia (CML) patients who achieved a deep molecular response for more than 2 years maintained a major molecular response after discontinuation of imatinib. These findings indicate the possibility that a portion of CML patients treated with Tyrosine kinase inhibitors (TKIs) could discontinue TKI therapy, although long-term prognosis and/or adverse events after TKIs cessation remain unclear. Recent reports showed that transient musculoskeletal pain occurs in approximately 30% of CML patients after stopping imatinib. To ascertain the factors underlying musculoskeletal events after TKI cessation, we investigated exosomal miRNA in five CML patients who did not experience musculoskeletal events and five patients with musculoskeletal pain after stopping TKIs.

Project description:The purpose of the study was to evaluate the efficacy and safety of vitamin D3 at 4000 IU/day as a treatment option for aromatase inhibitor-associated musculoskeletal symptoms (AIMSS) when compared with the usual care dose of 600 IU D3. We conducted a single site randomized, double-blind, phase 3 clinical trial in women with AIMSS comparing change in symptoms, reproductive hormones and AI pharmacokinetics. Postmenopausal women ?18 years with stages I-IIIA breast cancer, taking AI and experiencing AIMSS [breast cancer prevention trial symptom scale-musculoskeletal (BCPT-MS) subscale ?1.5] were admitted. Following randomization, 116 patients had a run-in period of 1 month on 600 IU D3, then began the randomized assignment to either 600 IU D3 (n = 56) or 4000 IU D3 (n = 57) daily for 6 months. The primary endpoint was a change in AIMSS from baseline (after 1 month run-in) on the BCPT-MS (general MS pain, joint pain, muscle stiffness, range for each question: 0 = not at all to 4 = extremely). Groups had no statistically significant differences demographically or clinically. There were no discernable differences between the randomly allocated treatment groups at 6 months in measures of AIMSS, pharmacokinetics of anastrozole and letrozole, serum levels of reproductive hormones, or adverse events. We found no significant changes in AIMSS measures between women who took 4000 IU D3 daily compared with 600 IU D3. The 4000 IU D3 did not adversely affect reproductive hormone levels or the steady state pharmacokinetics of anastrozole or letrozole. In both groups, serum 25(OH)D remained in the recommended range for bone health (?30 ng/mL) and safety (<50 ng/mL).

Project description:We profiled gene expression of purified cell types isolated from 5 musculoskeletal tissues: tendon, bone, muscle, cartilage and ligament. We then performed WGCNA to identify tissue-specific transcription factors, signaling pathways and cell surface receptors. The sequencing data for muscle cells is made available here.
