Primary breast diffuse large B-cell lymphoma characterized by CNS relapse and successful hematopoietic stem cell transplantation salvage therapy. J Formos Med Assoc 2024:S0929-6646(24)00053-6. [PMID: 38296697 DOI: 10.1016/j.jfma.2024.01.020] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/13/2023] [Revised: 01/02/2024] [Accepted: 01/20/2024] [Indexed: 02/02/2024] Open
Abstract
BACKGROUND Primary breast diffuse large B-cell lymphoma (PB-DLBCL) is rare, with a high incidence of central nervous system (CNS) relapse. This study aims to investigate clinical characteristics, prognostic factors, and outcomes in Taiwanese PB-DLBCL patients and review the literature on PB-DLBCL. METHODS Thirty-one PB-DLBCL patients diagnosed between 2000 and 2021 were retrospectively enrolled for analysis. RESULTS The median age was 49 (range 26-79) years. The complete remission (CR) rate was 90.3%. Nine (90%) of the ten patients who experienced relapse had CNS involvement at the time of relapse. The one-year, two-year, and five-year progression-free survival (PFS) rates were 86.6% (95% confidence interval [CI] 75.2-99.8), 75.8% (95% CI 61.6-93.2), and 45.1% (95% CI 29.5-68.9), respectively. The five-year overall survival (OS) rate was 64.1% (95 % CI 48.4-85.0). A stage-modified International Prognostic Index (mIPI) less than two (five-year PFS rate 52.5% vs. 17.1%, P = 0.02) and the achievement of CR after first-line treatment (two-year PFS rate 80.3% vs. 33.3%, P < 0.001) were significant favorable prognostic factors for PFS. Hematopoietic stem cell transplantation (HSCT) after the first relapse was associated with significantly improved post-relapse OS (five-year OS rate 85.7% vs. 20.0%, P = 0.02) and PFS (five-year PFS rate 85.7% vs. 20.0%, P = 0.02). CONCLUSION Patients with low-risk mIPI scores, CR after first-line treatment, and those who underwent HSCT after the first relapse had significantly better survival. Intrathecal chemotherapy conferred no benefit in preventing CNS relapse. Further research is needed to assess frontline HSCT's effectiveness in improving outcomes and preventing CNS relapses in PB-DLBCL patients.

Abstract
BACKGROUND Primary breast lymphoma (PBL) is a very rare form of non-Hodgkin's lymphoma (NHL), defined as a malignant primary lymphoma occurring in the breast in the absence of previously detected lymphoma localizations. Our study aims to retrospectively evaluate the epidemiological, clinical, and imaging findings and therapeutic features of breast lymphomas in patients with primary lymphoma of the breast. MATERIALS AND METHODS This is a retrospective study including 13 patients with primary non-Hodgkin's lymphoma of the breast treated at the Salah Azaiez Institute of Oncology from 2000 to 2019. This sample includes 1 case of follicular lymphoma, 2 cases of large T-cell lymphoma, and 10 cases of large B-cell lymphoma. RESULTS Patients included in the study were aged between 17 and 89 years (average age of 52.6 years). All patients were referred because of a lump in the breast, and only one patient consulted with inflammatory signs in the breast. The average clinical size of the tumor was 7.2 cm, with a maximum of 15 cm. Mammography showed an oval mass with circumscribed margins in the majority of cases. Ultrasound showed in most cases a hypoechoic irregular mass or multilobulated mass with irregular margins and hypervascular on color Doppler. Magnetic resonance imaging (MRI) was performed on only three patients and showed a spiculated lesion with polycyclic limits. Eight patients underwent surgery. In our study breast lymphomas involved 10 cases of large B-cell lymphoma, one case of follicular lymphoma, and two cases of large T-cell lymphoma. In this series, 11 patients had localized stages (I + II) at diagnosis, and 2 patients had disseminated stages (stage III) of primary breast lymphoma. Seven patients underwent chemotherapy treatment alone, and five had chemotherapy with radiotherapy. The median follow-up of our patients was 53 months, ranging from 1 to 177 months. Overall survival was 71% at 3 years and 51% at 5 years. CONCLUSION Primary breast lymphoma is an uncommon type of breast malignancy. The optimal treatment modality is still in question because of the rarity of this disease. However, the use of combination therapy produces the most favorable results. Surgery is not yet recommended.

Abstract
OBJECTIVE To explore whether the growth and treatment resistance of lymphoma and myeloma tumors is similar to that previously observed in leukemic and solid tumors growing in the same organ microenvironment. METHODS All published cases of 3 primary hematologic malignancies in breast, without systemic involvement, were identified, with follow-ups solicited from authors. Treatment approaches were analyzed to highlight the most effective. RESULTS Similar histologic features and biology among primary tumors of leukemia, lymphoma, plasmacytoma, and solid breast cancer was revealed. Review of treatments: tumor-directed, chemotherapy, or combination showed the benefit of tumor removal, and use of systemic agents in adjunct, not primary, treatment. Optimal assessment is limited by few cases of PET/CT verifying limited tumor extent. The common biology observed and cases of long survival after tumor/stroma eradication point to the complicity of organ microenvironment in the chemoresistance and treatment failure commonly observed in patients. CONCLUSIONS The interaction of an organ microenvironment, particularly its adipocytes, with malignant cells, results in similar histologic changes, metastatic potential, and chemoresistance in 3 hematologic malignancies and solid cancers. Improved survival in hematologic malignancies could result from adopting PET/CT to find tumor and its extent, eradicating tumor, and elucidating common therapeutic targets.

Abstract
Background Primary breast double-hit lymphoma (PB-DHL) is a rare, highly aggressive malignancy that poses challenges regarding accurate diagnosis and selecting optimal treatment regimens. Methods We retrospectively reviewed 48 cases of patients diagnosed with PB-DHL in six academic centres between June 2014 and June 2020 in China. Study-specific data were recorded, including treatment options, therapeutic evaluation, prognostic factors and relapse patterns, and the overall survival (OS) and progression-free survival (PFS) were evaluated. Results In total, 48 patients were enrolled, with 14 patients treated with DA-EPOCH-R/MA (rituximab, dose-adjusted etoposide, prednisone, vincristine, cyclophosphamide, doxorubicin, alternating with high-dose methotrexate and cytarabine), 18 patients treated with DA-EPOCH-R (rituximab, dose-adjusted etoposide, prednisone, vincristine, cyclophosphamide, doxorubicin), and 16 patients treated with R-HyperCVAD (rituximab, hyperfractionated cyclophosphamide, vincristine, doxorubicin, dexamethasone, alternating with cytarabine plus methotrexate). The overall 5-year OS and PFS rates were 41.7% (95% confidence interval [CI], 27.6–56.8%) and 37.5% (95% CI, 24.0–52.6%), respectively. Of the three treatment regimens, the 5-year OS was higher in DA-EPOCH-R/MA group than in the DA-EPOCH-R or R-HyperCVAD subgroups (57.1% vs. 38.9% vs. 31.3%; P = 0.016), as was the 5-year PFS (50.0% vs. 38.9% vs. 25.0%; P = 0.035). Autologous stem cell transplantation (ASCT) prolonged the OS and PFS compared with non-ASCT patients (5-year OS: 72.2% vs. 23.3%; P < 0.001; 5-year PFS: 72.2% vs. 16.7 %, P < 0.001). Multivariate analysis identified tumour size, risk stratification, treatment with DA-EPOCH-R/MA, breast irradiation, and ASCT as significant prognostic factors. Conclusions DA-EPOCH-R/MA is a promising regimen for PB-DHL, and breast irradiation yields complementary benefits for prognosis. ASCT significantly decreased disease relapse, providing a potential curative PB-DHL intervention and justifying ASCT as first-line therapy for young patients. More effective treatment strategies for PB-DHL patients remain encouraging. Supplementary Information The online version contains supplementary material available at 10.1186/s12935-021-02198-y.

Abstract
We performed a retrospective analysis of DLBCL with breast involvement to compare the prognosis of primary breast lymphoma (PBL) to secondary breast lymphoma (SBL; especially in limited stage cases). We retrospectively reviewed records of 25 diffuse large B-cell lymphoma (DLBCL) patients with breast involvement who received chemotherapy between January 2000 and August 2012. We compared clinical features and prognosis among patients with PBL (n = 11), limited stage SBL (LSBL; n = 6), and advanced stage SBL (ASBL, n = 8). The PBL group had significantly lesser patients with breast tumours (BTs) > 5 cm than the SBL group (P = 0.02). After a median follow-up of 71.3 months, we observed significantly better 5-year overall survival (OS) in the PBL group (90.0%) than in the LSBL (33.3%, P = 0.01) group, but not for progression-free survival (PFS). Patients with BT > 5 cm had worse OS (P = 0.01) and PFS (P = 0.04) than those with BT ≤ 5 cm. PBL had a better prognosis than SBL among limited stage DLBCL.

Abstract
Objectives: Primary breast diffuse large B-cell lymphoma (PB-DLBCL) and primary breast high-grade B-cell lymphoma (PB-HGBCL) are rare extranodal aggressive B-cell lymphomas with distinct characteristics. Reliable data regarding appropriate treatment of these specific entities are lacking due to their rarity.Methods: We reviewed 36 patients diagnosed at four Chinese medical centres between January 2008 and December 2018. Data regarding clinicopathological features, therapeutic evaluation and central nervous system (CNS) relapse were collected, and overall survival (OS) and progression-free survival (PFS) were calculated.Results: Among the 36 patients, there were 29 PB-DLBCL patients and 7 PB-HGBCL patients. The 5-year OS for PB-DLBCL and PB-HGBCL was 75.9% and 28.6%, respectively. The 5-year PFS for PB-DLBCL and PB-HGBCL was 69.0% and 14.3%, respectively. The R-DAEPOCH regimen was significantly more effective in PB-DLBCL patients than the R-CHOP regimen (5-year OS: 78.9% vs 62.5%, P=0.024; 5-year PFS: 73.7% vs 50.0%, P=0.037) but resulted in more severe myelosuppression (P=0.025). The rate of CNS relapse was 17.2% in PB-DLBCL patients and 28.6% in PB-HGBCL patients; the difference was not significant (P=0.602). The R-DAEPOCH regimen did not predominantly reduce CNS recurrence as expected (P=0.616). The Cox proportional hazards model revealed that risk stratification and triple expression were independent prognostic factors.Conclusion: Current treatments, including more intensive chemotherapy regimens, achieve good control of the disease. Novel drugs combined with cellular immunotherapy initially show promising therapeutic effects, and more clinical trials are required to confirm these effects further.

Abstract
Objective The pathogenesis of diffuse large B-cell lymphoma (DLBCL) has not yet been fully elucidated. An increasing number of studies have shown that circular RNAs (circRNAs) play an important role in tumorigenesis and development. The aim of this study was to investigate the effect of CircCFL1 on the malignant progression of DLBCL. Methods RT-qPCR was used to detect the expression levels of CircCFL1 and miR-107. A dual-luciferase reporter gene experiment was conducted to verify that CircCFL1 targeted miR-107 and the miR-107 target gene HMGB1. BrdU, transwell, and MTT tests were performed to detect cell invasion and proliferation. Western blot analysis was used to detect the phosphorylation of proteins. Xenograft models were established to confirm the effect of CircCFL1 on DLBCL tumor growth in vivo. Results The expression of CircCFL1 in cells transfected with the CircCFL1 overexpression vector was higher than that in the control group. After overexpressing CircCFL1, the expression of miR-107 in cells decreased significantly, and the protein level of HMGB1 increased. The dual-luciferase reporter gene experiment showed that CircCFL1 directly bound to miR-107 and reduced the inhibition of the target gene HMGB1. After CircCFL1 was overexpressed, cell migration and proliferation were enhanced. The tumor volume and weight in the lentivirus CircCFL1 group were higher than those in the lentivirus NC group. Conclusion Results showed that the circRNA CircCFL1 could regulate the expression of HMGB1 through miR-107 to promote the proliferation and migration of DLBCL.

Abstract
RATIONALE Pilot studies have reported that patients with systemic lupus erythematosus (SLE) appear more likely to develop into neoplasia, especially lymphatic hyperplasia diseases. To our knowledge, this is the first case report of the concomitant onset of SLE and primary breast diffuse large B-cell lymphoma (PB-DLBCL). PATIENT CONCERNS We reported an unusual case of the occurrence of primary breast diffuse large B-cell lymphoma in a 25-year-old female patient who had been diagnosed with SLE and treated with immunosuppressive drugs for about 4 years. She presented a 7-week history of a painless mass above the left breast and no history suggestive of any nipple discharge, fever, and weight loss. DIAGNOSIS Ultrasonography of the breast showed that there was 1 mass in the left breast. After breast mass surgical resection, histopathological examinations were performed and revealed that it was primary breast diffuse large B-cell lymphoma. INTERVENTIONS Treatment strategy with vincristine and dexamethasone was used to improve symptoms. However, the patient's renal function deteriorated and the blood potassium rose continuously and she and their family members refused the follow-up treatments. OUTCOMES The patient died 8 months after she was discharged from the hospital. LESSONS PB-DLBCL is a rare occurrence in SLE patients. Therefore, a careful examination is very important in SLE cohort, as activity of the disease and malignancy may mimic each other. Meanwhile, when symptoms cannot be explained or insensitive to treatment, the occurrence of malignant tumors must be highly considered.

Abstract
Introduction Primary breast lymphoma (PBL) is a rare malignancy that accounts for less than 0.5% of all breast malignancies. Materials and Methods We retrospectively analyzed 36 PBL patients to report the clinical characteristics and outcomes of patients with indolent and aggressive histologic subtypes. Results Thirteen (36%) patients had aggressive and 23 (64%) had indolent PBL. Marginal zone lymphoma was the most common histologic subtype (33%). Stage IE, IIE, and IV disease were seen in 27 (75%), six (17%), and three (8%) patients, respectively. Patients with aggressive PBL more often presented with a breast lump and/or B symptoms (unexplained weight loss, fever, night sweats) (78% vs. 31%, p = 0.005). Commonly used treatment modalities for aggressive vs. indolent PBL were chemotherapy alone (23% vs. 26%, p = 0.8), chemoradiotherapy (46% vs. 9%, p = 0.009), radiotherapy alone (15% vs. 22%, p = 0.6), and observation (0% vs. 26%, p = 0.07), respectively. The five-year overall survival (OS) and progression-free survival (PFS) of PBL patients were 82% (95% CI: 67 - 100) and 63% (95% CI: 45 - 89), respectively. The five-year OS of patients with aggressive vs. indolent PBL were 92% (95% CI: 77 - 100) vs. 80% (95% CI: 63 - 100), respectively (p = 0.6). The five-year OS of patients who received > 1, 1, and 0 treatment modalities were 92% (95% CI: 77 - 100), 86% (95% CI: 63 - 100), and 53% (95% CI: 21 - 100), respectively. Conclusion In our cohort, the higher utilization of chemoradiotherapy in aggressive PBL was able to overcome the worse prognosis of these patients. At least one treatment modality should be considered in patients with indolent PBL, given that observation alone was associated with a poor prognosis.

Abstract
BACKGROUND Primary lymphoma of the breast is rare, and primary diffuse large B cell lymphoma (DLBCL) of the breast is very rare. This study aimed to identify the clinicopathological characteristics and treatment associated with prognosis in patients with primary DLBCL of the breast. MATERIAL AND METHODS A retrospective study included the clinical and treatment data from 46 women with a histological diagnosis of primary DLBCL. Patients were staged using Ann Arbor staging criteria, overall survival (OS), progression-free survival (PFS), and the international prognostic index (IPI) scores were obtained. Laboratory finding included serum lactate dehydrogenase (LDH), and the immunohistochemistry findings were recorded. RESULTS Patients (n=46), included stage I (n=18), stage II (n=18), stage III (n=3), and stage IV DLBCL (n=9). Treatment included chemotherapy with rituximab (n=16), and radiotherapy (n=12). The median follow-up time was 40.5 months, the 5-year OS rate was 36.2%, and the 5-year PFS rate was 29.1%. Univariate analysis showed that clinical stage, serum LDH, the IPI score, chemotherapy cycles >3, and Bcl-2 and Bcl-6 expression were correlated with the 5-year OS and PFS. Multivariate risk regression analysis showed that the number of chemotherapy cycles (>3) and Bcl-6 expression were independent prognostic factors in primary DLBCL of the breast (P<0.05). CONCLUSIONS A retrospective study of 46 patients with primary DLBCL of the breast showed that >3 cycles of chemotherapy and expression of Bcl-6 resulted in improved OS and PFS. Radiotherapy controlled local tumor recurrence but did not improve the OS and PFS. Rituximab did not improve patient survival.
