Breast implants are associated with increased risk of breast-ALCL, but the absolute risk remains small. Our results emphasize the need for increased awareness among the public, medical professionals, and regulatory bodies, promotion of alternative cosmetic procedures, and alertness to signs and symptoms of breast-ALCL in women with implants.
In this study, we compared one hundred patients with autoimmune/inflammatory syndrome induced by adjuvants (ASIA) due to silicone implant incompatibility syndrome diagnosed in 2014 in Maastricht, the Netherlands, with one hundred historical patients with adjuvant breast disease diagnosed in the Baylor College of Medicine, Houston, USA, between 1985 and 1992. Similarities and differences between these two cohorts were identified to determine whether the spectrum of silicone-related disease changed during the last 30 years. Patients with complaints possibly due to silicone-filled breast implants were prospectively examined in the Reinaert Clinic, Maastricht, the Netherlands between January 2014 and October 2014. All patients were evaluated for the fulfilment of ASIA criteria. Results were compared to results of the Baylor College cohort and 18 other reviewed historical cohorts. Clinical manifestations between the Maastricht and Baylor College cohorts were comparable. Fatigue was observed in 98 current patients and in 95 historical patients. Arthralgia was observed in 91 versus 81 historical patients. Myalgia was observed in 54 versus 91 patients. Cognitive impairment was observed in 78 versus 81 patients, pyrexia was observed in 64 versus 52 patients, sicca complaints in 73 versus 72 patients and severe neurological manifestations in 20 versus 32 patients. From the 54 patients who underwent removal of their silicone breast implant, 50 % (n = 27) of the patients experienced improvement of complaints after explantation of the implant. Also, in the 18 reviewed historical cohorts, similar clinical manifestations were described. Our findings suggest that no major changes were present in the observed clinical manifestations between the Maastricht and Baylor College cohorts. Also, despite changes in the principal constituents of the silicone implants during the past fifty years, silicone remained an adjuvant that may ‘bleed’ and subsequently may be a chronic stimulus to the immune system resulting in similar clinical manifestations as observed in the Maastricht cohort, the Baylor College cohort and 18 other large cohorts of patients. We therefore conclude that silicone-related disease has not changed during the last 30 years.
In this review, we present a critical review of the existing literature reflecting the results of explantation of silicone breast implants in patients with silicone-related complaints and/or autoimmune diseases. A literature search was performed to discuss the following issues: which clinical manifestations and autoimmune diseases improve after explantation, and what is the course of these complaints after explantation. Next, we reviewed studies in which the effect of explantation on laboratory findings observed in patients with silicone breast implants was studied, and lastly, we reviewed studies that described the effect of reconstruction of the breast with a new implant or autologous tissue after explantation. We calculated from the literature that explantation of the silicone breast improved silicone-related complaints in 75 % of the patients (469 of 622). In patients with autoimmune diseases, however, improvement was only infrequently observed without additional therapy with immunosuppressive therapy, i.e., in 16 % of the patients (3 of 18). The effect of explantation did not influence autoantibody testing such as ANA. We discuss several possibilities which could clarify why patients improve after explantation. Firstly, the inflammatory response could be reduced after explantation. Secondly, explantation of the implants may remove a nociceptive stimulus, which may be the causative factor for many complaints. Options for reconstruction of the explanted breast are autologous tissue and/or water-/hydrocellulose-filled breast implant. Unfortunately, in very few studies attention was paid to reconstructive possibilities. Therefore, no adequate conclusion regarding this issue could be drawn. In conclusion, explantation is useful for improvement of silicone-related complaints in 75 % of the patients, whereas in patients who developed autoimmune diseases improvement is only observed when explantation is combined with immunosuppressive therapy. In a patient with silicone-related complaints in which explantation is considered, the patient should be counseled for the different options of reconstruction after explantation.
The role of cytopathology in malignant lymphoma is largely restricted to primary screening in patients with lymphadenopathy of unknown causes and evaluation of relapse and transformation during follow-up of patients with known and fully classified malignant lymphoma. Few lymphoma diagnoses fully rely on cytology, although breast-implant associated anaplastic large cell lymphoma is currently the centre of clinical attention. Due to the major attention both in the medical and lay media for the recently substantiated high lymphoma risk in women with breast implants, cytopathology departments now frequently receive seroma fluid aspirates with this specific differential diagnostic consideration. In this review, we discuss clinico-pathological aspects of breast-implant associated anaplastic large cell lymphoma from a cytological point of view and provide guidelines for the processing of aspirates in daily practice and strategies for diagnostic work-up of seroma fluids.

Breast implant-associated anaplastic large cell lymphoma (BIA-ALCL) is a very rare type of T-cell lymphoma, uniquely caused by a single environmental stimulus. Here we present a comprehensive genetic analysis of a relatively large series of BIA-ALCL (n=29), for which genome-wide chromosomal copy number aberrations (CNA) and mutational profiles for a subset (n=7) were determined. For comparison, CNAs for ALK-negative nodal-ALCLs (n=24) were obtained. CNAs were detected in 94% of BIA-ALCLs with losses at chromosome 20q13.13 in 66% of the samples. Loss of 20q13.13 is characteristic for BIA-ALCL as compared to other classes of ALCL, such as primary cutaneous ALCL, systemic type ALK-positive and -negative ALCL. Mutational patterns confirm that the IL6-JAK1-STAT3 pathway is deregulated. Although this is commonly observed across various types of T-cell lymphomas, the extent of deregulation however is significantly higher in BIA-ALCL as indicated by pSTAT3 immunohistochemistry. The characteristic loss of chromosome 20 in BIA-ALCL provides further justification to recognize BIA-ALCL as a separate disease entity. Moreover, CNA analysis may serve as a parameter for future diagnostic assays for women with breast implants to distinguish seroma caused by BIA-ALCL from other causes of seroma accumulation such as infection or trauma.
