Patel S, Shannon D, Eldridge W, El-Ters N, Hanford J, Walker T, Scheer A, Jones E, Linwood K, Aragon N, Dunscombe L, Gerbes J, Srinivasan N, Vachharajani A. Patel S, et al. J Matern Fetal Neonatal Med. 2022 Dec;35(25):5043-5048. doi: 10.1080/14767058.2021.1874908. Epub 2021 Feb 2. J Matern Fetal Neonatal Med. 2022. PMID: 33530795
Patients with at least 1 failed attempt at insertion were less likely to have a centrally placed UVC (p = .009). Manipulations were less likely to be required when UVC was centrally placed during the first attempt. Maneuvers such as posterior liver mobilization used during …

Factors influencing intrafractional target shifts in lung stereotactic body radiation therapy.
Liu HW, Khan R, Nugent Z, Krobutschek K, Dunscombe P, Lau H. Liu HW, et al. Pract Radiat Oncol. 2014 Jan-Feb;4(1):e45-51. doi: 10.1016/j.prro.2013.02.013. Epub 2013 Apr 9. Pract Radiat Oncol. 2014. PMID: 24621431
The tumor volume, tumor location (upper vs lower thorax), and the patient motion tendency were significantly associated with the probability of larger intrafractional shifts (3D shift >5 mm). Linear regression model analysis indicated male sex (P = .039), larger tumor v …

Beaulieu L, Evans DA, Aubin S, Angyalfi S, Husain S, Kay I, Martin AG, Varfalvy N, Vigneault E, Dunscombe P. Beaulieu L, et al. Int J Radiat Oncol Biol Phys. 2007 Jan 1;67(1):71-7. doi: 10.1016/j.ijrobp.2006.07.019. Epub 2006 Sep 25. Int J Radiat Oncol Biol Phys. 2007. PMID: 16997500
The postplan D90 was 151.2 Gy for I1 and 167.3 Gy for I2, well above the 140 Gy from the Stock et al. analysis, taking into account differences at planning, results in a p value of 0.0676. The procedure time required on average 174.4 min for I1 and 89 min for I2. ...

Clinical impact of using the deterministic patient dose calculation algorithm Acuros XB for lung stereotactic body radiation therapy.
Liu HW, Nugent Z, Clayton R, Dunscombe P, Lau H, Khan R. Liu HW, et al. Acta Oncol. 2014 Mar;53(3):324-9. doi: 10.3109/0284186X.2013.822552. Epub 2013 Aug 19. Acta Oncol. 2014. PMID: 23957683 Clinical Trial.

Compared to AAA, a small and significant difference in dose distribution in the target was found for the Acuros XB algorithm, resulting in lower conformity (-2.1%, p < 0.0001) and higher heterogeneity (p < 0.0001) of dose. Single logistic regression identified

Inter- and intra-observer variability in prostate definition with tissue harmonic and brightness mode imaging.
Sandhu GK, Dunscombe P, Meyer T, Pavamani S, Khan R. Sandhu GK, et al. Int J Radiat Oncol Biol Phys. 2012 Jan 1;82(1):e9-16. doi: 10.1016/j.ijrobp.2011.02.013. Epub 2011 Apr 12. Int J Radiat Oncol Biol Phys. 2012. PMID: 21489703
RESULTS: A one-sample Student t-test showed the volumes outlined by five observers are in agreement (p > 0.05) with the RO. Paired Student t-test showed prostate volumes (p = 0.008) and midgland areas (p = 0.006) with H mode were significantly smaller than …

Quantitative vs. subjective portal verification using digital portal images.
Bissett R, Leszczynski K, Loose S, Boyko S, Dunscombe P. Bissett R, et al. Int J Radiat Oncol Biol Phys. 1996 Jan 15;34(2):489-95. doi: 10.1016/0360-3016(95)02035-7. Int J Radiat Oncol Biol Phys. 1996. PMID: 8567353

For all four oncologists, the portals classified as unacceptable, in terms of the field placement, exhibited significantly higher (p < 0.03) translational errors in the transverse direction. The field coverages were significantly lower (p < 0.05) and the trans

Spearman's correlation coefficient analysis suggested a strong relationship between notification rates and material deprivation (r = 0.58 [p value = 0.009 for a two-tailed test]). A similar association was also observed for unemployment (r = 0.51 [p value = 0.02 for …
