Witryna14 sty 2024 · Radiation therapy (RT) plays an important role in lung cancer treatment, but grade 2 or higher radiation pneumonitis (RP2) remains an essential dose-limiting obstacle and can significantly reduce the therapeutic ratio and patient’s quality of life [1,2,3].Lung volume receiving more than 20 Gy (V20) and mean lung dose (MLD) … WitrynaA lobectomy is the removal of an entire lobe of the lung. It is currently thought to be the most effective type of surgery, even when the lung tumor is very small. Clinical trials are underway to study if less extensive surgeries have similar outcomes for tumors that are 2 centimeters or smaller. A wedge resection.

WitrynaWhen compared to the tangential plans, SIB-IMRT maintained coverage (V95%) to the left breast and lumpectomy bed without significantly increasing the left breast maximum dose. SIB-IMRT was able to reduce the lung mean dose, maximum dose, and the V20 by 55–104 cGy, 983–1298 cGy (p < 0.001), and 3.7–4.4%, respectively.
