Hippocampal-sparing whole-brain radiotherapy using Elekta equipment.

The purpose of this study was to evaluate the feasibility of hippocampal-sparing whole-brain radiotherapy (HS WBRT) using the Elekta Infinity linear accelerator and Monaco treatment planning system (TPS). Ten treatment plans were created for HS-WBRT to a dose of 30 Gy (10 fractions). RTOG 0933 recommendations were applied for treatment planning.

CT appearances of post-radiation livers in patients with unresectable cholangiocarcinoma.

Objective: To characterize the computed tomographic (CT) findings of post-radiation livers and the interval changes in patients with unresectable cholangiocarcinoma.

Material And Method: Thirteen patients with unresectable cholangiocarcinoma who received concurrent chemoradiation with conformal radiotherapy technique (50 to 66 Gy, 2 Gy/fraction) were included in the present study. CT at pre-radiation and sequential follow-up at 1, 3, 6, 9 and 12 months were retrospectively reviewed by two abdominal radiologists to identify CT characteristics of post-radiation liver and the interval changes.

Economic evaluation of policy options for prevention and control of cervical cancer in Thailand.

Background: The Thai healthcare setting has seen patients with cervical cancer experience an increasing burden of morbidity and mortality, a stagnation in the performance of cervical screening programmes and the introduction of a vaccine for the prevention of human papillomavirus (HPV) infection.

Objective: This study aims to identify the optimum mix of interventions that are cost effective, from societal and healthcare provider perspectives, for the prevention and control of cervical cancer.

Methods: A computer-based Markov model of the natural history of cervical cancer was used to simulate an age-stratified cohort of women in Thailand.
