The Gamma Knife (GK) Icon (Elekta AB) uses a cone-beam computed tomography (CBCT) scanner and an infrared camera system to support the delivery of frameless stereotactic radiosurgery (SRS). There are limited data on patients treated with GK (GKRS).To describe early experience, process, technical details, short-term outcomes GKRS at our institution.We reviewed patient selection described workflow in detail, including image acquisition, treatment planning, mask-based immobilization, CBCT...
Biological systems contain biochemical control networks that reside within a remarkable spatial structure. We present theoretical study of biological system in which two chemically coupled species, an activating species and inhibiting forming negative feedback, are synthesized at unique sites interact with each other through diffusion. The dynamical behaviors these depend on the locations synthetic sites. In feedback sites, we find modes: fixed point stable oscillations whose frequency can...
The radiotherapy (rt) volumes in anaplastic (atc) and differentiated thyroid carcinoma (dtc) are controversial.We retrospectively examined the patterns of failure after postoperative intensity-modulated rt for atc dtc. Computed tomography images were rigidly registered with original plans. Recurrences considered in-field if more than 95% recurrence volume received prescribed dose, out-of-field less 20% marginal otherwise.Of 30 dtc patients, 4 developed regional recurrence: 1 being (level...
The global rise in cancer incidence has been accompanied by disproportionately high morbidity and mortality rates low- middle-income countries. Many patients who are offered potentially curative treatment for cervical countries never return to start reasons that poorly documented little understood. We investigated the interplay of sociodemographic, financial, geographic factors as barriers care among such Botswana Zimbabwe.Patients seen consultation between 2019 2021 were >3 months late an...
Mucoepidermoid carcinoma of the maxillary sinus is a rare malignancy head and neck. The location this tumour near vital structures its large size at presentation makes surgical resection with negative margins challenging. In incurable cases, relief from symptoms such as epistaxis may be achieved radiation therapy. We present case mucoepidermoid that was effectively palliated short course therapy, achieving complete cessation bleeding, decrease in size, long term control. surveyed literature...
PURPOSE For many oncology training programs in low- and middle-income countries, dedicated time for research education mentorship of trainees is limited. Here, we report a 1-year–long collaboration between cancer center Canada one Ghana with the aim imparting clinical skills mentoring radiation residents. METHODS On basis needs assessment conducted Ghana, designed curriculum consisting 13 weekly seminars delivered via videoconference, followed by program to support projects. The primary...
Abstract Background Conventional radiotherapy at a dose of 50 Gy in 25 fractions after breast conservative surgery is the standard treatment for ductal carcinoma situ (DCIS). Hypofractionation an interesting alternative cancer, providing less intense scheme patient. While hypofractionated regimen 42.5 16 has been shown to be equivalent infiltrating carcinoma, few studies and no prospective study have reported results using hypofractionation DCIS. Materials Methods: In this multicenter...
