BACKGROUND Radiation-induced heart disease (RIHD), which affects the patients' prognosis with both acute and late side effects, has been published extensively in the radiotherapy of breast cancer, lymphoma and other benign diseases. Studies on RIHD in lung cancer radiotherapy, however, are less extensive and clear even though the patients with lung cancer are delivered with higher doses to the ...

background: we aimed to compare field-in-field technique (fif) with conformal tangential field radiotherapy (crt) in terms of dosimetric benefits for early stage breast cancer radiotherapy. materials and methods: twenty consecutive left-side breast cancer patients who underwent breast-conserving surgery were included to the study. for each patient, two different treatment plans were created for...

The present study compared the dose-volume histograms of patients with Stage IIIA non-small cell lung cancer (NSCLC) treated with carbon ion radiotherapy with those of patients treated with X-ray radiotherapy. Patients with Stage IIIA NSCLC (n = 10 patients for each approach) were enrolled. Both radiotherapy plans were calculated with the same targets and organs at risk on the same CT. The trea...

There is a raging argument amongst Oncologist regarding offering low dose lung radiotherapy in patients with covid infection symptoms. huge enthusiasm medical fraternity and appetite to offer experimental therapies so as contribute managing this pandemic associated morbidity mortality.Although the intentions are noble, like Low without adequate scientific scrutiny risk causing more harm than go...

Background and aims: Lung cancer is the leading cause of cancer death worldwide. There are no recent data on the lung cancer prevalence in Lebanon, and the available data are based on prediction. Thus, this study aimed to determine the incidence rate of lung cancer during 2014, among patients who were newly diagnosed at Lebanese teaching hospitals. In addition, the study attempted to identify t...

BACKGROUND Tamoxifen is an anti-estrogen with proven efficacy and low toxicity in the treatment of breast cancer. However, tamoxifen has been shown to exert a number of nonhormonal as well as hormonal effects. One nonhormonal effect of tamoxifen is the induction of transforming growth factor-beta (TGF-beta) secretion. TGF-beta has been implicated in the pathogenesis of radiation-induced fibrosi...

Introduction: The functionality and quality of any treatment planning system (TPS) strongly depends on the type of Algorithm which is used by it. Obviously, the role of dose distribution algorithms in calculation of prescribed dose inside the tumor in modern radiotherapy techniques has more important than past to achieve the best clinical outcomes, especially in tumors which ar...

introduction: 99mtc-mibi has been proposed for use as an imaging agent for various tumors, including breast cancer, lung cancer, lymphomas, melanomas and brain neoplastic lesions. brain tumors are very common and radiotherapy being major part of treatment following surgery. after radiotherapy, deteriorating clinical status can be due to either radiation necrosis or recurrent tumor. computed tom...
