AIM The development of chemoradiation - the concurrent administration of chemotherapy and radiotherapy - has led to significant improvements in local tumor control and survival. However, it is limited by its high toxicity. In this study, we report the development of a novel NP (nanoparticle) therapeutic, ChemoRad NP, which can deliver biologically targeted chemoradiation. METHOD A biodegradab...

Though early stage head and neck cancers can be cured either by surgery or radiation, patients with locally advanced disease continues to pose a therapeutic challenge. Locoregional failure is the major cause of death in head and neck cancers. As the outcome of locally advanced head and neck cancer is less than promising, a combined modality approach is generally undertaken in this group of pati...

We present the case of an 83 year old woman with a cardiac pacemaker located close in distance to a subsequently diagnosed invasive ductal carcinoma of the left breast. Short range intraoperative radiotherapy was given following wide local excision and sentinel node biopsy. The challenges of using ionising radiation with pacemakers is also discussed.

objective(s): in this study we evaluate the impact of the different aspects of gold nano-particles (gnps) on the target absorptive dose enhancement factor (def) during external targeted radiotherapy with photon beams ranging from kilovolt to megavolt energies using monte carlo simulation. methods: we have simulated the interaction of photon beams with various energies of radiation using water s...

The developments of medicine always follow innovations in science and technology. In the past decade, such innovations have made cancer-related targeted therapies possible. In general, the term "targeted therapy" has been used in reference to cellular and molecular level oriented therapies. However, improvements in the delivery and planning of traditional radiation therapy have also provided ...

: Leptomeningeal disease (LMD) is a poor prognosis pattern of progression in patients with metastatic malignancy limited treatment options. Patients may be asymptomatic or present non-specific neurologic deficits, therefore gadolinium-enhanced magnetic resonance imaging the brain and spine critical for establishing diagnosis. Although intent palliative context LMD, multidisciplinary approach st...
