Background: Breast implant–associated anaplastic large-cell lymphoma is a rare disease with a favourable prognosis if adequately treated. Same staged patients have usually a similar prognosis and outcomes, but in our experience, IIA-staged patients have a wider prognosis with outcomes that vary from complete disease response to death. This study aimed to understand and identify all the factors that could influence the prognosis of this group of patients and verify if their prognosis matches the stage they belong to. Material and methods: Patients in stage IIA have been divided into two subgroups: IIAb with lymphoma extension towards the glandular tissue and IIAcw with tumour extension towards the chest-wall. The overall survival (OS) and event-free survival (EFS) of 64 BIA-ALCL cases were evaluated for each staged group. Results: Significant differences of OS and EFS between IIAb and IIAcw patients (log-rank p = 0.046 and log-rank p = 0.018, respectively) were observed and poor prognosis joined IIAcw- and IV-staged patients. Conclusion: Chest-wall infiltration is a critical prognostic factor in BIA-ALCL patients as it influences the possibility of performing a surgical radical tumour extirpation. Our results could represent valid assistance for the physicians in choosing the most appropriate BIA-ALCL prognostic category and treatment and could promote further wider studies to provide stronger evidence on a possible revision of the MDA TNM classification.

Abstract

Background: Breast implant–associated anaplastic large-cell lymphoma is a rare disease with a favourable prognosis if adequately treated. Same staged patients have usually a similar prognosis and outcomes, but in our experience, IIA-staged patients have a wider prognosis with outcomes that vary from complete disease response to death. This study aimed to understand and identify all the factors that could influence the prognosis of this group of patients and verify if their prognosis matches the stage they belong to. Material and methods: Patients in stage IIA have been divided into two subgroups: IIAb with lymphoma extension towards the glandular tissue and IIAcw with tumour extension towards the chest-wall. The overall survival (OS) and event-free survival (EFS) of 64 BIA-ALCL cases were evaluated for each staged group. Results: Significant differences of OS and EFS between IIAb and IIAcw patients (log-rank p = 0.046 and log-rank p = 0.018, respectively) were observed and poor prognosis joined IIAcw- and IV-staged patients. Conclusion: Chest-wall infiltration is a critical prognostic factor in BIA-ALCL patients as it influences the possibility of performing a surgical radical tumour extirpation. Our results could represent valid assistance for the physicians in choosing the most appropriate BIA-ALCL prognostic category and treatment and could promote further wider studies to provide stronger evidence on a possible revision of the MDA TNM classification.
