Background: To determine which radiotherapy parameters are associated with the tumor response of locally advanced non-small cell lung cancer (NSCLC) patients undergoing concurrent chemoradiotherapy. Materials and Methods: Thirty one patients with IIIA/IIIB NSCLC underwent chemoradiotherapy with a median dose of 63 Gy. On our actual treatments, we made radiotherapy planning to cover the planning...

Introduction: Intensity Modulated Radiotherapy (IMRT) is a common method for treating prostate cancers. Different IMRT methods can apply for irradiating the prostate, but there is not clear that which of these methods can provide better dose distribution for each patient individually. Therefore, the aim of this study was to evaluate the relationship between the different prosta...

BACKGROUND The dose distribution to the rectum, delineated as solid organ, rectal wall and rectal surface, in 3D conformal (3D-CRT) and intensity-modulated radiotherapy treatment (IMRT) planning for localized prostate cancer was evaluated. MATERIALS AND METHODS In a retrospective planning study 3-field, 4-field and IMRT treatment plans were analyzed for ten patients with localized prostate ca...

PURPOSE To present the results of dose homogeneity analysis for breast cancer patients treated with image-based conformal interstitial brachytherapy, and to investigate the usefulness of the ICRU recommendations. MATERIAL AND METHODS Treatment plans of forty-nine patients who underwent partial breast irradiation with interstitial brachytherapy were analyzed. Quantitative parameters were used ...

PURPOSE To evaluate the radiation dose-volume effects of optic nerves and chiasm by visual psychophysical, electrophysiologic tests, and optical coherence tomography in patients with locally advanced nasopharyngeal carcinoma. MATERIALS AND METHODS A series of visual tests including visual acuity, visual field, contrast sensitivity, visual evoked potential, and optical coherence tomography wer...

the antitumor activity of ethanol extract of prosopis glandulosa torr. (epg) was evaluated against ehrlich ascites carcinoma (eac) tumor model in swiss albino mice on dose dependent manner. the activity was assessed using survival time, average increase in body weight, hematological parameters and solid tumor volume. oral administration of epg at the dose of 100, 200 and 400 mg/kg, significantl...

AIMS AND BACKGROUND Radiotherapy-related kidney injury is multifactorial and influenced by radiation dose-volume distributions, patient-related factors, and chemotherapy. Traditional radiation parameters for the kidney are based on pre-intensity-modulated radiotherapy (IMRT) data and focus on limiting the volume receiving high dose. We report a case of testicular seminoma with paraaortic adenop...
