Proteomic analysis of treatment-resistant, stem-like cancer cells.
منشور في 2013"…We further propose that both tumorspheres and committed cells respond to the stress of radiotherapy by up-regulating survivin, perhaps as a survival mechanism to evade radiation-induced apoptosis. We propose that a stressor to the primary tumor will induce the transitional cell phenotype and may account for both the resistant late recurrences and metastatic deposits observed in high-risk tumors.…"

Quantitative imaging of lymph function
منشور في 2007"…The etiology for trauma-associated, acquired lymphedema is thought to arise from the interruption of lymph channels coupled with postsurgical infection or radiation-induced skin reaction. The onset of symptoms, however, can occur from days, weeks, to years following the initial trauma, striking at a rate cited between 6 and 62.5% of breast cancer survivors who have undergone axillary lymph node dissection (1, 26, 38), up to 64% of all patients who undergo groin dissections (8), and 25% of all radical hysterectomy patients (4). …"
