Curr Oncol
. 2016 Apr;
23(2):e86-94.
PMID: 27122989
Background: Non-small-cell lung cancer (nsclc) is associated with very poor overall survival because 70% of patients present with locally advanced or metastatic disease at the time of diagnosis. Micrornas (mirnas)...

Technol Cancer Res Treat
. 2012 Sep;
12(1):79-90.
PMID: 22974332
The physical properties of I-131 may be suboptimal for the delivery of therapeutic radiation to bone marrow metastases, which are common in the natural history of neuroblastoma. In vitro and...

Barnes E, Murray B, Robinson D, UNDERWOOD L, Hanson J, Roa W
Int J Radiat Oncol Biol Phys
. 2001 Jun;
50(4):1091-8.
PMID: 11429237
Purpose: To examine the dosimetric benefit of self-gated radiotherapy at deep-inspiration breath hold (DIBH) in the treatment of patients with non-small-cell lung cancer (NSCLC). The relative contributions of tumor immobilization...

Yee D, Hao C, Cheung H, Chen H, Dabbagh L, Hanson J, et al.
Clin Invest Med
. 2001 May;
24(2):76-82.
PMID: 11368149
Objective: Glioblastoma cells produce cytokines with proinflammatory or immunosuppressive properties, or both, which, in addition to altered p53 gene expression, have been shown to be associated with glioblastoma resistance to...

Cancer Res
. 2001 Feb;
61(3):1162-70.
PMID: 11221847
Tumor necrosis factor-related apoptosis-inducing ligand (TRAIL) preferentially triggers apoptosis in tumor cells versus normal cells, thus providing a therapeutic potential. In this study, we examined a large panel of human...

Int J Radiat Oncol Biol Phys
. 2001 Feb;
49(1):43-9.
PMID: 11163496
Purpose: To examine the feasibility of a held-breath self-gating (HBSG) technique in the radiotherapy of lung cancer. Material And Methods: Sixteen consecutive eligible and consenting patients undergoing radiotherapy for non-small-cell...

Med Phys
. 1999 Dec;
26(11):2367-72.
PMID: 10587218
Three-dimensional conformal radiotherapy allows the use of tightly conformed, multiple coplanar or noncoplanar beams. However, visualizing the spatial relationships between the target volume and adjacent critical structures is not always...

Implantation metastasis of primary central nervous system lymphoma complicating radiotherapy outcome
Roa W, Kim D, Halls S, Murray B
Am J Clin Oncol
. 1999 Feb;
22(1):29-31.
PMID: 10025375
Computed tomography-guided stereotactic biopsy is commonly used in the diagnosis of brain lesions. An uncommonly reported risk of the procedure is the potential of implantation metastasis. This phenomenon has been...

Roa W, Miller G, McEwan A, McQuarrie S, Tse J, Wu J, et al.
Int J Radiat Oncol Biol Phys
. 1998 Jun;
41(2):425-32.
PMID: 9607361
Purpose: Iodine-125 induces cell death by a mechanism similar to that of high linear energy transfer (high-LET) radiation. This study investigates the cytotoxicity of high-specific-activity [125I]meta-iodobenzylguanidine (125I-mIBG) in human SK-N-MC...
