(i) Parameter-adding: the EBRT DVH parameters (or the EBRT prescription dose) were added to the unregistered HDR-BT DVH parameters. (ii) Distribution-adding: the parameters were extracted after the EBRT doses were 3D-summed with the registered HDR-BT doses. Resulting differences between the parameters were investigated. Results: The D0.1cc, D1cc and D2cc from parameter-adding were 21.3% (P < 0.001), 6.3% (P < 0.001) and 3.5% (P < 0.001) smaller than those from distribution-adding. The D10cc was 2.2% (P=0.015) larger for distribution-adding. Conclusion: Distribution-adding was confounded by unsystematic inter/intra-observer rectum-contouring errors and registration accuracy near the anterior rectal wall. Consequently, clinical use of distribution-adding to assess rectal doses requires careful contour and registration evaluation.]]> Thu 28 Oct 2021 13:04:40 AEDT ]]> 18F-FDG PET-CT performed before and during radiation therapy of head and neck squamous cell carcinoma: are they independent or complementary to each other? https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:29991 18F-FDG PET-CT performed before definitive radiation therapy (RT) (prePET) in patients with mucosal primary head and neck squamous cell carcinoma (MPHNSCC) and to assess the additive prognostic values of FDG PET-CT performed during RT (iPET). Methods: One hundred patients with MPHNSCC treated with radical RT underwent staging prePET and iPET performed during the third week of treatment. The maximum standardized uptake value (SUVmax), metabolic tumour volume (MTV) and total lesional glycolysis (TLG) of primary tumour were analysed for both prePET and iPET, and results were correlated with loco-regional recurrence-free survival (LRFS), disease-free survival (DFS), metastatic failure-free survival (MFFS) and overall survival (OS), using Kaplan–Meier analysis. Optimal cut-offs (OC) for prePET and iPET were derived from Receiver Operating Characteristic curves. Patients with metabolic parameters above/below the individual OC of prePET as well as iPET (i.e. combined prePET and iPET (comPET)) were evaluated against their outcomes. Results: Median age was 61 years (range 39–81), median follow-up of 20 months (range 4–70, mean 27), and AJCC 7th Edition clinical stage II, III and IV were 8, 24 and 68 patients respectively. Metabolic values below individual OC in comPET were found to be associated with statistically significant improvements (P < 0.05) in DFS, LRFS and OS. In addition, patients with SUVmax above the OC in comPET were associated with worse MFFS (P = 0.011) and confirmed on both univariate (P = 0.019) and multivariate analyses (P = 0.04). Conclusion: Addition of iPET significantly improves the prognostic values of all three metabolic parameters and can potentially be used in future adaptive local and systemic therapy trials.]]> Thu 28 Oct 2021 12:36:43 AEDT ]]> Multi-observer contouring of male pelvic anatomy: highly variable agreement across conventional and emerging structures of interest https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:42132 Thu 25 Aug 2022 16:25:22 AEST ]]> Adoption of hypofractionated radiation therapy for early breast cancer in private practice: the GenesisCare experience 2014–2106 https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:43269 Thu 15 Sep 2022 12:11:44 AEST ]]> Comparison of prostate set-up accuracy and margins with off-line bony anatomy corrections and online implanted fiducial-based corrections https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:5608 Sat 24 Mar 2018 11:04:40 AEDT ]]> Comprehensive Australasian multicentre dosimetric intercomparison: issues, logistics and recommendations https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:8352 Sat 24 Mar 2018 10:47:13 AEDT ]]> Quality assurance audit: a prospective non-randomised trial of chemotherapy and radiotherapy for osteolymphoma (TROG 99.04/ALLG LY02) https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:7373 Sat 24 Mar 2018 08:40:16 AEDT ]]> Serum procollagen 1 amino-terminal propeptide (P1NP) in prostate cancer: pitfalls of its use as an early surrogate marker for bone metastasis https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:20769 Sat 24 Mar 2018 08:00:21 AEDT ]]> Incremental changes verses a technological quantum leap: the additional value of intensity-modulated radiotherapy beyond image-guided radiotherapy for prostate irradiation https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:20392 Sat 24 Mar 2018 07:58:08 AEDT ]]> Effect of androgen deprivation therapy on muscle attenuation in men with prostate cancer https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:17874 Sat 24 Mar 2018 07:56:44 AEDT ]]> Obstacles to participation in randomised cancer clinical trials: a systematic review of the literature https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:21763 Sat 24 Mar 2018 07:53:06 AEDT ]]> FROGG high-risk prostate cancer workshop: patterns of practice and literature review: part I: intact prostate https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:21357 Sat 24 Mar 2018 07:51:27 AEDT ]]> FROGG high-risk prostate cancer workshop: patterns of practice and literature review: part II post-radical prostatectomy https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:28752 Sat 24 Mar 2018 07:37:36 AEDT ]]> Technical quality assurance during the TROG 03.04 RADAR prostate radiotherapy trial: are the results reflected in observed toxicity rates? https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:26791 Sat 24 Mar 2018 07:36:30 AEDT ]]> Comparison of roentgenographic manifestations of active pulmonary tuberculosis between migrant and non-migrant populations in the Hunter Region https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:26595 Sat 24 Mar 2018 07:34:02 AEDT ]]> Utilisation of MR spectroscopy and diffusion weighted imaging in predicting and monitoring of breast cancer response to chemotherapy https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:25640 Sat 24 Mar 2018 07:28:09 AEDT ]]> Involved-field radiotherapy for patients with mantle cell lymphoma https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:26649 Sat 24 Mar 2018 07:26:50 AEDT ]]> Adapting to a global pandemic through live virtual delivery of a cancer collaborative trial group conference: the TROG 2020 experience https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:38564 P < 0.0001).

Conclusion: Only 30% of patients with high-risk features are referred to a radiation oncologist with the likelihood of referral being influenced by the perceived risk of cancer-recurrence as well as the urologist’s institutional/personal preference. When patients are seen by a radiation oncologist, 61% receive radiotherapy within 6 months after RP with the likelihood of receiving radiotherapy not being heavily influenced by increasing risk of recurrence. This suggests many suitable patients would receive radiotherapy if referred and seen by a radiation oncologist.]]> Fri 29 Jul 2022 13:51:38 AEST ]]> A retrospective 4D-MRI based on 2D diaphragm profiles for lung cancer patients https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:45465 Fri 28 Oct 2022 14:30:41 AEDT ]]> Fostering a culture of research within a clinical radiation oncology department https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:46579 Fri 25 Nov 2022 13:39:41 AEDT ]]> The status of radiation oncology teaching in Australian and New Zealand medical schools https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:41774 Fri 12 Aug 2022 11:56:45 AEST ]]> Implementation of the Australian Computer-Assisted Theragnostics (AusCAT) network for radiation oncology data extraction, reporting and distributed learning https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:41747 Fri 12 Aug 2022 11:28:41 AEST ]]>
