Breast implant-associated anaplastic large cell lymphoma (BIA-ALCL) has received increasing interest among plastic surgeons as a long-term complication of breast augmentation. Although the prognosis is usually good, mortality is a possible outcome. Most of the cases reported in the past two decades have been from the United States, Europe, and Australia, whereas cases of BIA-ALCL in Asia remain rare. Herein, we describe the first known case of BIA-ALCL in Thailand, in which a 32-year-old woman developed BIA-ALCL 3 years after breast augmentation using textured implants. The patient underwent bilateral removal of the implants and ipsilateral total capsulectomy. This case report—the first of its kind from Thailand—should increase awareness of BIA-ALCL among plastic surgeons in Asia. The true incidence of BIA-ALCL in Asia may be underreported.

Background:
MYC/BCL2 double expression (DE) is associated with poor prognosis in patients with diffuse large B-cell lymphoma (DLBCL) receiving rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisolone (R-CHOP).This study aimed to determine whether the addition of DE to the National Comprehensive Cancer Network Internal Prognostic Index (NCCN-IPI) could improve the prediction of disease progression in patients with DLBCL treated with R-CHOP.
Methods:
This confirmatory prognostic factor study retrospectively recruited patients with newly diagnosed DLBCL between January 1, 2014, and January 31, 2018, at Ramathibodi Hospital (RA) and Thammasat University Hospital (TU).The follow-up period ended on July 1, 2022. Tumors expressing MYC ≥ 40% and BCL2 ≥ 50% were classified as DE. We calculated the hazard ratios (HR) for progression-free survival (PFS) from the date of diagnosis to refractory disease, relapse, or death. Discrimination of the 5-year prediction was based on Cox models using Harrell’s concordance index (c-index).
Results:
A total of 111 patients had DE (39%), NCCN-IPI (8%), and disease progression (46%). The NCCN-IPI adjusted HR of DE was 1.6 (95% confidence interval [CI]: 0.9–2.8; P = 0.117). The baseline NCCN-IPI c-index was 0.63. Adding DE to the NCCN-IPI slightly increased Harrell’s concordance index (c-index) to 0.66 (P = 0.119).
Conclusions
Adding DE to the NCCN-IPI may not improve the prognostic value to an acceptable level in resourcelimited settings. Multiple independent confirmatory studies from a large cohort of lymphoma registries have provided additional evidence for the clinical utility of DE.
