RESUMO
Facial skin cancer (FSC) is prone to incomplete excision due to the sophisticated anatomy and the aesthetic importance of the face. In this study, we sought to investigate to what extent sex-specific differences and other operation-, patient-, and cancer-specific factors influence the re-resection rate in FSC surgery, in order to provide personalized treatment strategies to patients. In this retrospective study, patients (>18 years) undergoing surgical excision of an FSC were enrolled. Each patient's demographic data, cancer location, the surgical team, primary and secondary surgeries were analyzed. Overall, 469 patients (819 surgeries) were included. The mean age was 69 ± 15 years. No significant association between sex-specific factors (surgeon's sex (OR: 1.09, 95% CI: 0.76-1.56) or patient's sex (OR: 0.85, 95% CI: 0.62-1.17), surgeon-patient sex concordance and discordance) and the likelihood of secondary surgery were found. However, healing by secondary intention (OR: 4.28; 95% CI: 1.94-9.45) and cancer location showed an increased re-resection rate. In conclusion, FSC surgery is a safe method unaffected by sex-specific factors, which had no impact on the re-resection rate. However, in further analysis, the likelihood of a re-resection was influenced by other factors such as healing by secondary intention and cancer location. This knowledge might be useful to provide an algorithm for personalized treatment strategies in the future.
RESUMO
The interest in gluteal augmentation using minimally invasive techniques has been increasing rapidly. Despite the fact that Aquafilling filler was described as biocompatible with human tissues, the number of associated complications has been rising. We present an exceptional case of a 35-year-old female patient, who suffered major long-term complications in association with Aquafilling filler injections in the gluteal region. The patient was referred to our center with signs of recurrent inflammation and severe pain focusing on the left lower extremity. A computed tomography (CT) scan showed multiple, communicating abscess formations all the way from the gluteal region to the lower leg. Therefore, an operative debridement was accomplished in the operating theater. Finally, this report emphasizes the severity of possible long-term complications when using Aquafilling filler especially in larger areas. Furthermore, the oncogenicity as well as toxicity of polyacrylamide, the core material of Aquafilling filler, remains uncertain, which is why further research is urgently required.
