Background: Postmastectomy radiation therapy is increasingly indicated in patients with node-positive breast cancer. The authors prospectively evaluated long-term outcomes in patients with two-stage implant-based reconstruction and postmastectomy radiation therapy to the permanent implant.
Methods: A cohort of 1415 patients operated on by a single surgeon from 1998 to 2010 was evaluated annually. Outcomes were recorded prospectively. Complication rates were compared between irradiated and nonirradiated implants, including reconstructive failure (implant loss), complications (e.g., capsular contracture), aesthetic results, and satisfaction. Predicted implant loss and replacement rates were examined by irradiation status with Kaplan-Meier analysis and the log-rank test.
Results: A total of 2133 breast implant reconstructions with a mean follow-up of 56.8 months (range, 12 to 164 months) were included. Three hundred nineteen implants received radiation. Implant loss occurred in 9.1 percent of irradiated implants and 0.5 percent of nonirradiated implants (p < 0.01). Capsular contracture grade IV was present in 6.9 percent of irradiated and 0.5 percent of nonirradiated implants (p < 0.01). There was no difference between groups regarding implant replacement. Ninety-two percent of irradiated patients had good to excellent aesthetic result, and 94.2 percent would choose implants again. Predicted implant loss rates were 17.5 percent and 2.0 percent for irradiated and nonirradiated implants, respectively, at 12 years (p < 0.01), and predicted implant replacement rates were 12.7 percent and 8.8 percent, respectively, at 8 years (p = not significant).
Conclusions: This is the largest prospective long-term outcomes evaluation in women with immediate tissue expander/implant reconstruction and postmastectomy radiation therapy. Most patients had a good to excellent aesthetic result and preserve their reconstruction at 12 years.
Clinical Question/level Of Evidence: Therapeutic, III.

The purpose of this study was to evaluate the effect of a single dose of ionizing radiation (30 Gy) on the osseointegration of implants in the rabbit tibia. Twenty rabbits received two dental Morse-tapered junction implants and one implant in each tibia. The animals were randomly divided into two groups (n=10), non-irradiated (NoIr) and irradiated (Ir), wherein the Ir group received a single dose of 30 Gy radiation 2 weeks after implant installation.

Photodynamic implants are an increasingly popular minimally invasive option for the surgical treatment of metastatic bone disease. Following surgery, adjuvant radiation therapy (RT) is frequently administered to achieve better disease control and improve patient quality of life, but the role of RT in implant failures associated with photodynamic implants remains unclear. The aim of this study is to determine if the therapeutic RT range of 10-50 Gy affects the biomechanical properties of photodynamic implants.

Background: Cardiac arrhythmia has been reported as a significant complication of thoracic radiotherapy. Both bradyarrhythmias and tachyarrhythmias have been reported, highlighting the arrhythmia-modulating potential of radiation in certain oncologic therapies. This study aimed to analyse the arrhythmic burden in patients with cardiac implantable electrical devices (CIEDs) undergoing thoracic irradiation, examining both immediate effects of radiotherapy and long-term sequelae post-therapy.

Background: Breast cancer is the most common cancer among women. Partial mastectomy is an alternative to mastectomy in early-stage breast cancer to restore a poor quality of life (QOL). However, the aesthetic satisfaction with this procedure is inadequate.
