Background Aromatase inhibitors (AI) are well established as adjuvant endocrine treatment for postmenopausal women with hormone receptor-positive (HR+) early breast cancer (EBC). Drug-induced myalgia or arthralgia is among the most frequently reported adverse drug reactions to AIs. Objectives Little is known about the pathomechanism by which AIs cause muscle and joint injury. The literature on skeletal muscle complaints with AIs is confusing, in part because of a lack of clear definitions. Myalgia/arthralgia is defined as muscle/joint pain and is likely to affect patients’ quality of life and compliance with AI medication . We designed a prospective trial to collect real world data on the e…
Droloxifene-Induced Spikes of Tumor Markers Predict Benefit of Therapy
1991
In the clinical monitoring of cancer, tumor marker proteins may reflect the status of the disease. In cases with radio- and chemotherapy, spikes of tumor markers were found shortly after starting the therapy. These spikes were interpreted as a sign of tumor lysis. Recently during therapy of breast cancer with the new antiestrogen droloxifene, spikes of CA 125 and CA 15-3 were also found in about one-third of patients responding to therapy. The peaks of these initial increases were recorded between 14 and 60 days after the onset of treatment, with maximum concentrations up to 1,890% of the initial value. Marker concentrations decreased thereafter, to new baselines at or below the initial val…
