Concomitant Chemoradiotherapy With Image-guided Pulsed Dose Rate Brachytherapy as a Definitive Treatment Modality for Early-stage Cervical Cancer.

PURPOSE: Concurrent chemoradiotherapy (CRT) is the standard of care for patients with bulky cervical cancer. This study aimed to determine the feasibility, tolerance, and effectiveness of pulsed dose rate (PDR) image-guided brachytherapy (IGBT), utilizing magnetic resonance imaging (MRI) planning after CRT for stages IB2 and II cervix cancer patients. METHODS AND MATERIALS: This study planned to include patients with histologically confirmed stage IB2 and II cervical cancer who were treated with CRT followed by a PDR IGBT boost from January 2009 to December 2009 in our institution. All patients had at least a partial response after CRT before IGBT. The institutional review board approved the study. Patients received a 45-Gy external beam radiotherapy (EBRT) to the pelvis with concomitant weekly cisplatin (40 mg/m) for 5 cycles. All patients then underwent reimaging using MRI before BT. The IGBT boost was accomplished with one insertion using an MRI-compatible tandem and ovoid applicator delivering 30 to 35 Gy to a high-risk clinical target volume. Treatment-induced adverse events (AEs), dose parameters, local control, progression-free survival, and overall survival are reported. RESULTS: Forty patients were included in this study, with ages ranging from 31 to 65 years (median age, 45 y). Of all the patients, 12.5% and 5% experienced grade 3 to 4 acute gastrointestinal and genitourinary AEs, respectively, and 2.5% and 2.5% had grade 3 to 4 chronic gastrointestinal and genitourinary AEs, respectively. Within a median follow-up of 30 months (range, 7 to 40 mo), local control was 90%, progression-free survival was 87.5%, and overall survival was 100%. CONCLUSIONS: Intracavitary MRI PDR-IGBT boost after CRT is a feasible, tolerable, and effective treatment modality for patients with stages IB2 and II cervical cancer.

Open eye injuries in the pediatric population in Kuwait.

OBJECTIVE: To report the epidemiological characteristics of pediatric open globe injuries and to discuss treatment, management and outcomes of such injuries. MATERIALS AND METHOD: The hospital records and operative notes of 95 patients 16 years old and younger who were treated for open eye injury at Ibn Sina Hospital, Kuwait between September 1995 and January 1999 were reviewed. The average age of patients was 6.6 years. Patients were divided into three groups according to their final visual acuity (FVA): group 1, FVA of 20/40 or better; group 2, 20/40-20/200, and group 3, 20/400 or worse. The FVA of each group was compared to initial visual acuity (IVA), wound entry site, injury-to-presentation interval, injury-to-surgery interval, time of surgery, duration of surgery, associated injuries and medical treatment. RESULTS: Injury was most common in children 3-6 years old. Most injuries occurred during play at home (46%), between the months of July and November (58%), and evening time (42%). The most common causes were glass, pencil, stick, soft drink bottle, metal bar, and stone. The cornea was the most common entry site (59 cases). Seventy-three patients presented on the day of injury, and 38 of them had surgical repair that same day. The follow-up period ranged from 2 weeks to 58 months. Thirty-eight patients (40%) had an FVA of 20/40 or better (group 1), 23 (24%) between 20/40 and 20/200 (group 2), 12 (13%) 20/400 or worse (group 3), and 22 (23%) had no record of FVA. The difference between IVA and FVA of wound entry site was statistically significant (p < 0.005). Differences due to injury-to-presentation interval, injury-to-surgery interval, time of surgery, duration of surgery, associated injuries, and the use of systemic antibiotics were found not to be statistically significant (p > 0.2). CONCLUSION: The prevalence of open globe injury among the pediatric population in Kuwait was high. Most injuries were due to household objects and occurred at home in the evening during the summer and autumn. IVA and anatomical location of the wound impacted on final outcome.
