Complications and Patient-Reported Outcomes in Breast Cancer Patients Undergoing Prepectoral Implant-Based Breast Reconstruction Followed by Postmastectomy Radiation Therapy
In prepectoral implant-based breast reconstruction followed by postmastectomy radiation therapy, the direct-to-implant approach demonstrated significantly lower rates of reconstructive failure, infection, and severe capsular contracture compared to the tissue expander-to-implant approach, while maintaining comparable overall patient-reported outcomes.

When a woman faces breast cancer, the decision to remove the breast is often a necessary step to save her life. For many, the journey does not end with the surgery; it continues with the desire to restore the body's shape. In recent years, a technique called immediate breast reconstruction has become a standard option, allowing the breast to be rebuilt right after the mastectomy. One popular method involves placing a silicone implant just under the skin but above the chest muscle. This approach, known as prepectoral reconstruction, avoids cutting into the muscle, which can reduce pain and prevent the unnatural movement of the implant that sometimes happens when muscle is involved. However, for patients with higher-risk cancers, radiation therapy is a critical treatment to prevent the disease from returning. Radiation can be tough on the skin and tissues, and doctors have long debated whether it is safer to place the final implant immediately or to use a temporary, inflatable balloon first to stretch the skin before swapping it for the permanent implant.
A team of researchers at the Tianjin Medical University Cancer Institute and Hospital set out to settle this question by looking at real-world outcomes. They reviewed the medical records of 217 women who had undergone prepectoral reconstruction followed by radiation therapy. The women were divided into two groups based on their surgical path. The first group received a direct-to-implant approach, where the permanent silicone implant was placed immediately after the mastectomy and before radiation. The second group followed a two-stage path: they received a tissue expander, a temporary device that is gradually filled with salt water to stretch the skin, underwent radiation, and then had the expander replaced with a permanent implant months later. The researchers tracked these patients for complications such as infection, the need for additional surgeries, and the development of scar tissue that hardens around the implant, a condition known as capsular contracture. They also asked the women to rate their own satisfaction and quality of life using a detailed survey called the Breast-Q.
The study revealed a clear difference in the physical risks between the two methods. Women who went through the two-stage process with the tissue expander faced significantly higher rates of trouble. In this group, 14.5 percent of the reconstructive efforts failed, meaning the implant had to be removed or the process abandoned, compared to only 3.7 percent in the group that received the permanent implant immediately. Infections were also more common in the two-stage group, occurring in 13.6 percent of patients versus 3.7 percent in the immediate group. Perhaps most notably, the women who had the tissue expander were more likely to develop severe hardening of the scar tissue around the implant, with 30.2 percent experiencing this complication compared to 14.0 percent in the immediate group. The researchers found that the use of the tissue expander itself was an independent factor that increased the risk of failure, and that infections were strongly linked to the loss of the reconstruction.
Despite these higher physical risks, the story of how the patients felt about the results was surprisingly similar. When the researchers compared the women's self-reported satisfaction with their breasts, their psychological well-being, and their overall happiness with the outcome, there was no significant difference between the two groups. Both groups reported high levels of satisfaction, suggesting that even with the higher complication rates, the women in the two-stage group still felt their reconstruction was successful. There was one notable exception regarding intimacy: women in the two-stage group reported a significant boost in sexual well-being after they finally swapped the temporary expander for the permanent implant. This improvement likely came from the fact that the second surgery allowed doctors to adjust the shape and release tight scar tissue, refining the final look and feel. However, even with this specific gain, the overall satisfaction scores between the two groups remained comparable.
The findings suggest that for patients requiring radiation after prepectoral reconstruction, the simpler, one-step approach of placing the permanent implant immediately may be the safer choice. While the two-stage method was once thought to be a way to protect the implant from radiation damage, this study indicates that the extra surgery and the presence of a temporary device actually introduced more opportunities for infection and failure. The researchers noted that the immediate implant group avoided these extra risks while achieving the same level of patient happiness. The study does have limitations, as it was a single-center review and the follow-up period was not extremely long, but the data points strongly toward the immediate method being a viable and often preferable option. Ultimately, the research offers a clear path forward: for many women facing this difficult combination of surgery and radiation, skipping the temporary expander and going straight to the final implant appears to reduce complications without sacrificing the emotional reward of restoration.
