Purpose: To retrospectively evaluate the outcomes and complications of curative radiotherapy for locoregionally recurrent non-small cell lung cancer (NSCLC). Materials and Methods: From 2004 to 2008, 21 patients received curative radiotherapy for locoregionally recurrent NSCLC without systemic metastasis after surgery. At the time of recurrence, the median age was 70 years (range 49∼81 years), ...

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 cr...

Introduction Radiotherapy with small fields is used widely in newly developed techniques. Additionally, dose calculation accuracy of treatment planning systems in small fields plays a crucial role in treatment outcome. In the present study, dose calculation accuracy of two commercial treatment planning systems was evaluated against Monte Carlo method. Materials and Methods Siemens Once or linea...

BACKGROUND Evidence shows ionizing radiation can cause lung cancer, but few studies have quantified risk in relation to radiation dose. PURPOSE This study evaluated the long-term risk of lung cancer among women treated with radiation for breast cancer. METHODS In this case-referent study, the Connecticut Tumor Registry was used to identify women diagnosed with histologically confirmed invas...

OBJECTIVE Radiotherapy is an important treatment for cancer. The main irradiated action is thought to be the irreversible damage to tumor cell DNA, but recent studies showed that high dose radiotherapy related to the tumor immune response. This study was designed to determine the relationship between Lewis lung tumor radiosensitivity and CD4+CD25+ regulatory T cells (Tregs) infiltration and elu...

Introduction:   The aim of this study is to investigate the effect of respiratory motion during radiation therapy in patient with lung cancer and comparison of dosimetric parameters between Intensity modulation radiation therapy and three-dimensional conformal radiotherapy in lung cancer.   Materials and Methods:   Two CT scan was performred for each pati...

Objective: Lung cancer is the most common worldwide and among leading causes of death. The aim this study to examine survival patients who received radiotherapy for brain metastases, whose primary non-small cell lung cancer, also determine factors that are like affect results in these as well. Materials Methods: This included 99 with cancer. All metastases radiotherapy. were grouped compared ac...

Background: Breast conserving surgery (BCS) followed by radiotherapy (RT) has been widely accepted as the standard treatment in early stages of invasive breast cancer. The standard technique of RT includes whole breast irradiation (WBI). Additional tumor bed boost irradiation has also an important role in the local tumor control. But there are various controversial delivery methods. The aim of ...

Background: The standard treatment for locally advanced non-small cell lung cancer (LA-NSCLC) is represented by concomitant chemo-radiotherapy followed consolidation with durvalumab that ensures a 5-year survival of 46%. However, the risk radiotherapy-induced pneumonia (RIP) almost 10–15%. Complete cardiological examination also usually performed during cardiopulmonary pre-treatment evaluation ...
