An Active Breathing Coordinator (ABC) can be employed to induce breath-holds during CT imaging and radiotherapy of lung, breast and liver cancer, and recently during lung cancer MRI. The apparatus measures and controls respiratory volume, hence subject lung volume reproducibility is its principal measure of effectiveness. To assess ABC control quality, the intra-session reproducibility of ABC-i...
Multifocal small, deep and subsolid lung nodules are increasingly discovered incidentally, often harboring early malignancies. In these cases, lung-preservation rather than major resection is the optimal strategy of choice. We retrospectively reviewed all treated by electromagnetic navigation bronchoscopy (ENB) transbronchial microwave ablation between March 2019 January 2022. Among these, we e...
AIMS To investigate patterns of practice in palliative radiotherapy in Africa. MATERIALS AND METHODS Fifteen centres in Africa provided detailed information about radiotherapy in both metastatic and locally advanced disease via a questionnaire. Information included general information (institution status, equipment, staff, patient number), radiotherapy and other treatment characteristics in b...
Objective(s): Semiconductor zinc oxide nanoparticles (ZnO NPs) have unique properties, such as inherent selectivity and photosensitization effects under ultraviolet (UV) radiation. ZnO NPs serve as promising anticancer agents. However, UV radiation limits their penetration into the body. In most clinical settings, it is essential to use high-energy photons in the treatment of deep-seated tumors...
BACKGROUND Limited data describe the prognosis after stereotactic ablative radiotherapy for lung metastases arising from colorectal cancer. Thus, we evaluated treatment outcomes of stereotactic ablative radiotherapy for those patients. METHODS The study involved patients received stereotactic ablative radiotherapy for one to three lung metastases arising from colorectal cancer at a single ins...
We report a patient with nasopharyngeal cancer with long-term follow-up of more than 16 years after the first course of radiotherapy in 1981. He developed a lung metastasis in 1996 after having a second course of radiotherapy for neck recurrence in 1989. The patient was a 42-year-old man with a nasopharyngeal tumor and a fixed upper neck metastasis (T1N1M0), which was treated with definitive ra...
Radiotherapy has been the mainstay of treatment of stage III nonsmall cell lung cancer patients. In the early 90s, combined treatment with chemotherapy was introduced. In 1995, a meta-analysis showed improved treatment outcome of the sequential use of cisplatin-based chemotherapy and radiotherapy compared to radiotherapy alone. Subsequent randomized studies and two meta-analyses demonstrated th...
Selection of lung cancer treatment should be based on tumour characteristics, physiological reserves and preferences of the patient. Our aims were to identify and quantify other factors associated with treatment received. Lung cancer patient data from 2002 to 2011 were obtained from the national population-based Cancer Registry of Norway, Statistics Norway and the Norwegian Patient Register. Mu...
Breast radiotherapy is a technical challenge in women with pectus excavatum. We aim to assess isocentric lateral decubitus (ILD) technique as a means to irradiate breasts for patients with pectus excavatum. Four women presenting with left-sided breast cancers and found to have pectus excavatum were offered breast-conserving treatments. Post-operative breast radiotherapy was indicated (50 Gy) in...
