https://www.selleckchem.com/products/brivudine.html .Purpose To evaluate the usefulness of quantitative findings of pretherapy lymphoscintigraphy in predicting the effects of complex decongestive therapy (CDT) in patients with upper extremity lymphedema after breast cancer treatment. Methods and Results We retrospectively analyzed patients with unilateral breast cancer-related lymphedema (BCRL) who underwent pretherapy lymphoscintigraphy and completed 2 weeks of CDT. A total of 18 patients with unilateral BCRL clinical stage II underwent 30-minute sessions of CDT five times per week for 2 weeks. The quantitative asymmetry index (QAI) of the upper extremity, axillary lymph node (LN) uptake, and axillary plus supraclavicular LN uptake from lymphoscintigraphy were calculated. The volume of lymphedema was calculated by percentage excess volume (PEV) at initial and posttreatment. The CDT response was assessed using percentage reduction in excess volume (PREV). Correlation analyses were conducted using Kendall tau rank correlation. There was positive correlation between upper extremity QAI at 2 hours and initial PEV. Negative correlations were found between axillary LN QAI at 1, 2 hours, and initial PEV, and between axillary plus supraclavicular LN QAI at 1, 2 hours, and initial PEV. The PREV showed a positive correlation with axillary LN QAI at 2 hours after injection (tau-b = 0.354, p = 0.041). Conclusion Quantitative findings of pretherapy lymphoscintigraphy have potential value for use in predicting the response to CDT in patients with upper extremity lymphedema after breast cancer treatment. Using QAIs from lymphoscintigraphy, we could estimate the excess volume of lymphedema.Although the physical and biologic principles of radiation therapy have remained relatively unchanged, a technologic renaissance has led to continuous and ever-changing growth in the field of radiation oncology. As a result, medical devices, techniques, and indications have changed considerably
