Prognostic value of Bcl2 and Bcl6 in primary cutaneous large B-cell lymphoma: A systematic review and meta-analysis. Pathol Res Pract 2022; 232:153812. [PMID: 35220171 DOI: 10.1016/j.prp.2022.153812] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/05/2021] [Revised: 02/10/2022] [Accepted: 02/18/2022] [Indexed: 12/19/2022]
Abstract
AIMS To assess the prognostic value of Bcl2 and Bcl6 in primary cutaneous diffuse large B-cell lymphoma (pcDLBCL), through a systematic review and meta-analysis. METHODS Electronic databases were searched from their inception to April 2021 for studies reporting Bcl2 and Bcl6 expression and survival outcomes in pcDLBCL series. Kaplan-Meier and Cox regression survival analyses with hazard ratio calculation were performed for overall survival (OS), with a significant p-value< 0.05. RESULTS Eight studies with 148 patients were included. OS was significantly decreased in Bcl2-pos itive pcDLBCLs (5-year OS= 52.9 ± 5.2%) compared to Bcl2 negative pcDLBCLs (5-year OS= 86.6 ± 7.2%), with a HR of 4.615 (95% CI, 1.827-11.657; p = 0.001); no significant difference in OS was found between Bcl6-positive pcDLBCLs (5-year OS= 61.3 ± 6.5%) and Bcl6-negative pcDLBCLs (5-year OS= 56.8 ± 7.2%), with a HR of 0.789 (95% CI, 0.462-1.350; p = 0.388). CONCLUSIONS In pcDLBCL, Bcl2 expression is a strong unfavourable prognostic marker; Bcl6 does not seem to be associated with survival instead. Further studies are necessary in this field.

Abstract
OBJECTIVES Several studies suggested that CD30 expression is a favorable prognostic marker in transformed mycosis fungoides (tMF). However, evidence in this field is still unclear. This systematic review and meta-analysis aimed to evaluate the prognostic significance of CD30 in tMF. METHODS Electronic databases were searched from their inception to June 2020 for all studies assessing the prognostic value of CD30 in tMF. Pooled hazard ratio (HR) for death was calculated; a P value less than .05 was considered significant. Inconsistency index (I2) was used to assess statistical heterogeneity among studies. RESULTS Seven studies with 323 patients were included. CD30 expression in tMF was significantly associated with a decreased hazard of death both on univariate (HR, 0.459; 95% confidence interval [CI], 0.319-0.660; P < .001) and multivariate analysis (HR, 0.503; 95% CI, 0.345-0.734; P < .001), and the statistical heterogeneity among studies was null in all analyses (I2 = 0%). CONCLUSIONS tMF cases with CD30 expression in large cells have a hazard of death two times lower than CD30-negative cases.

Prognostic value of Bcl2 and p53 in Hodgkin lymphoma: A systematic review and meta-analysis. Pathol Res Pract 2021; 219:153370.

Abstract
AIMS Several studies suggested that high expression of Bcl2 and/or p53 in Hodgkin/Reed-Sternberg cells is an unfavorable prognostic factor in Hodgkin lymphoma (HL). However, results in this field appear contrasting. We aimed to assess the prognostic value of p53 and Bcl2 in HL through a systematic review and meta-analysis. METHODS Electronic databases were searched from January 2000 to December 2020 for all studies assessing the prognostic value of p53 and Bcl2 in HL. The association of high p53 or Bcl2 expression with overall survival (OS), progression-free survival (PFS) and response to treatment was assessed by using hazard ratio (HR) and odds ratio (OR). RESULTS Eighteen studies were included. Bcl2 overexpression was significantly associated with decreased PFS (HR = 2.202; p < 0.0001), while the associations with decreased OS (HR = 1.565; p = 0.257) and refractoriness to treatment (OR = 0.482; p = 0.068) were non-significant. p53 overexpression was not significantly associated with refractoriness to treatment (OR = 0.904; p = 0.155); the analysis of OS and PFS was not feasible, but published data suggested the absence of a significant association. CONCLUSIONS In HL, Bcl2 overexpression is associated with decreased PFS, while a significant prognostic value could not be demonstrated for p53. Defining optimal criteria for interpreting Bcl2 and p53 immunostaining is necessary to draw definitive conclusions.

Abstract
HIV infection is considered a major risk factor for primary central nervous system lymphoma (PCNSL). However, the percentage of PCNSL that occurs in HIV + patients is not well defined. We aimed to assess the prevalence of HIV infection in patients with PCNSL through a systematic review and meta-analysis. Electronic databases were searched for studies assessing the presence of HIV infection in series of patients with PCNSL. Pooled prevalence of HIV infection in PCNSL was calculated, with a subgroup analysis based on the geographic area. Twenty-seven studies with 6422 patients were included. Overall, pooled prevalence of HIV infection among PCNSL patients was 6.1 % with high heterogeneity. In the subgroup analysis, pooled prevalence was 3.6 % in India with low heterogeneity, 30.2 % (overall) and 16.5 % (after 2000) in the USA with high heterogeneity, 5.7 % in Europe with high heterogeneity, 2.2 % in East Asia with null heterogeneity, 7.3 % in South America with moderate heterogeneity. In conclusion, only a minor part of PCNSL occurs in patients with HIV. The results stratified by geographic area reflect the different prevalence of HIV infection in the general population, except for India, probably due to the shorter life expectancy of HIV + patients.

Abstract
The maintenance of inner integrity of an organism is founded on the proper performance of two immunity branches, innate and adaptive immune responses. Recently, it became apparent that subset of splenic B cells named marginal zone B cells (MZB cells) exhibits unique developmental and functional features that bridge these two immunity branches. Strategically positioned at the site where blood and lymph are filtered, MZB cells represent a population of sentinels that rapidly proliferate and differentiate into IgM plasmablast cells when encountered with blood-borne, thymus-independent (TI) Ags. Moreover, MZB cells have intrinsic capability to induce potent CD4+ helper T cell response and cytokine production upon stimulation with soluble antigens. Due to their ability to overcome a time gap prior the establishment of the full adaptive response towards pathogens, MZB cells connect and direct innate and adaptive immunity. An additional interesting characteristic of MZB cells is capacity to function as regulatory cells in autoimmune processes. MZB cells may also contribute to the control of autoimmunity via the induction of tolerance by apoptotic cells. Importantly, in the clear association with inflammation and autoimmunity, MZB cells may transform into MALT lymphoma, representing a concurrence point for the infection, immunity and malignancy. This paper presents an insight into the complex biology of marginal zone B cells and their role in intertwining and directing innate and adaptive immune processes at the physiological and pathological level.

Involvement of Helicobacter Pylori in Ocular Adnexa Lymphoma. Pathol Oncol Res 2020; 26:2075-2081. [PMID: 32557170 DOI: 10.1007/s12253-020-00848-6] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/03/2019] [Accepted: 06/11/2020] [Indexed: 12/19/2022]
Abstract
Helicobacter pylori has been proposed as a possible etiologic factor of ocular adnexa lymphoma (OAL), although with conflicting results. To assess the involvement of H. pylori in OAL, as (1) H. pylori DNA positivity on OAL specimens, and (2) prevalence of H. pylori gastric infection in patients with OAL. A systematic review of studies assessing H. pylori in patients with OAL was conducted by searching electronic databases from their inception to May 2019. Pooled positivity for H. pylori in OAL specimens detected by polymerase chain reaction, and pooled prevalence of H. pylori gastric infection, were calculated with 95% confidence interval (CI). Eleven studies with 308 patients were included. Pooled positivity for H. pylori was 16.8% in all OALs and 22.7% in MALT OAL, with high heterogeneity among studies. Pooled prevalence of H. pylori gastric infection in patients with OAL was 34.7%, with low statistical heterogeneity. In conclusion, H. pylori seems to be involved in a subset of OAL, but the heterogeneity found needs to be investigated in further studies. The prevalence of H. pylori gastric infection in patients with OAL does not seem to differ from that of the general population.
