Publikováno v: Oncotarget

Aberrant activation of Rho GTPase Rac1 has been observed in various tumor types, including pancreatic cancer. Rac1 activates multiple signaling pathways that lead to uncontrolled proliferation, invasion and metastasis. Thus, inhibition of Rac1 activi

Publikováno v: Technology in Cancer Research & Treatment

Purpose: Pinnacle Auto-Planning and Eclipse RapidPlan are 2 major commercial automated planning engines that are fundamentally different: Auto-Planning mimics real planners in the iterative optimization, while RapidPlan generates static dose objectiv

A comparison of clinical and radiologic outcomes between frame-based and frameless stereotactic radiosurgery for brain metastases

Autor: Kyle A. Denniston, Timothy D. Malouff, Chi Lin, Weining Zhen, Abhijeet R. Bhirud, Vivek Verma, Nathan R. Bennion, Andrew O. Wahl

Publikováno v: Practical Radiation Oncology. 6:e283-e290

Purpose Modern experiences in stereotactic radiosurgery (SRS) report noninvasive frameless techniques as an effective alternative to frame-based SRS. Frameless techniques potentially increase positional uncertainty and planning target volume margins

Accelerated partial breast radiotherapy: a review of the literature and future directions

Autor: Andrew O. Wahl, Nathan R. Bennion, Michael J. Baine, Andrew Granatowicz

Breast conservation therapy exemplifies the tailoring of medicine in the care of patients with cancer. Akin to improvements in surgical approaches, accelerated partial breast irradiation (APBI) tailors the treatment volume and duration to the needs o

A comprehensive dosimetric study on switching from a Type-B to a Type-C dose algorithm for modern lung SBRT

Autor: Christina Zhou, Andrew O. Wahl, Shuo Wang, Xiaoying Liang, Weining Zhen, Sumin Zhou, Megan A Hyun, Dandan Zheng, Nathan R. Bennion, R Ma, Xiaobo Li, Kristina Zvolanek, Chi Lin

Publikováno v: Radiation Oncology (London, England)
Radiation Oncology, Vol 12, Iss 1, Pp 1-11 (2017)

Background Type-C dose algorithms provide more accurate dosimetry for lung SBRT treatment planning. However, because current dosimetric protocols were developed based on conventional algorithms, its applicability for the new generation algorithms nee
