Simple Summary: Prostheses are highly beneficial as they reduce the need for formal healthcare and support services, but they are not without side effects. Despite advancements, issues such as implant rejection and perioperative complications persist, and new concerns have arisen, including the potential link between long-term prosthetic use and cancer, specifically lymphoma. While the overall risk of developing lymphoma from prosthetic implants remains low, it is essential to explore the factors contributing to this risk. This highlights the need for ongoing research into the safety and long-term effects of prosthetic devices. Based on this evidence, we conducted a descriptive analysis using individual patient data from primary studies to investigate the relationship between lymphomas and different types of prosthetic devices, excluding breast implants. Background: Medical devices used for functional or esthetic purposes improve health and quality of life; however, they are not risk-free. Anaplastic large-cell lymphoma (ALCL), associated with breast implants, is a well-known and recognized distinct lymphoma entity. More recently, additional lymphomas have been reported in relation to prosthesis other than breast implants, as these allow the pericyte to develop into a clone that undergoes a maturation process, progressing toward full malignancy. Methods: We performed a systematic review with a descriptive analysis of data extracted from primary studies following PRISMA guidelines, including the search string "(IMPLANT* OR PROSTHES*) AND LYMPHOM*" in the PubMed, Scopus, Embase, and Google-Scholar databases. Data such as patient sex, age, implant site, prosthesis material, and lymphoma type were analyzed. Statistical methods, including Student's t-test and Fisher's exact test, were employed to compare lymphoma characteristics, with significance set at a p-value < 0.05. Results: From a total of 5992 studies, we obtained 43 case reports and series on a total of 52 patients diagnosed with prosthesis-associated lymphomas. The majority of implant-related lymphoma cases (85%) were of the B-cell type, mostly fibrin-associated large B-cell lymphoma (LBCL). This lymphoma type was more associated with biological (non-human-derived biological tissue), metallic, and synthetic implants (synthesized from non-organic components) (p-value = 0.007). Patients with ALCL had equal frequencies of metal and silicone prostheses (37.5%, 3 cases each), followed by synthetic prostheses (25%, 2 cases). ALCL cases were most common at skeletal (50%) and muscular-cutaneous sites (25%), whereas B-cell lymphomas were predominantly found in cardiovascular implants (50%), followed by skeletal (27%) and muscular-cutaneous (21%) sites. Death attributed to lymphoma took place in 67% of the cases, mostly LBCL occurring in cardiovascular sites. Conclusions: Because the included studies were limited to case reports and series, a potential non-causal link might have been documented between different implant materials, implant sites and lymphoma types. This underscores the importance of further comprehensive research and monitoring of non-breast implants. [ABSTRACT FROM AUTHOR] |
