Nasopharyngeal carcinoma is a malignancy from epithelial cells predominantly associated with the Epstein-Barr virus (EBV) infection, and it is responsible for 140,000 deaths annually. There is a current need to develop new strategies to increase the efficacy of antineoplastic treatment and reduce side effects. Thus, the present study aimed to perform a systematic review and meta-analysis of the ability of photodynamic therapy (PDT) to modulate the tumor microenvironment and PDT efficacy in nasopharyngeal carcinoma treatment. The reviewers conducted all steps in the systematic review. PubMed, Science Direct, Scopus, Scielo, Lilacs, EMBASE, and the Cochrane library databases were searched. The OHAT was used to assess the risk of bias. Meta-analysis was performed with a random-effects model (α = 0.05). Nasopharyngeal carcinoma cells treated with PDT showed that IL-8, IL-1α, IL-1β, LC3BI, LC3BII, MMP2, and MMP9 levels were significantly higher than in groups that did not receive PDT. NF-ĸB, miR BART 1-5p, BART 16, and BART 17-5p levels were significantly lower in the PDT group than in the control group. Apoptosis levels and the viability of nasopharyngeal carcinoma cells (>70%) infected with EBV were effective after PDT. This treatment also increased LMP1 levels (0.28-0.50/ < 0.05) compared to the control group. PDT showed promising results for efficacy in killing nasopharyngeal carcinoma cells infected with EBV and modulating the tumor microenvironment. Further preclinical studies should be performed to validate these results.
鼻咽癌是一种主要与爱泼斯坦-巴尔病毒(EBV)感染相关的上皮细胞恶性肿瘤,每年导致14万人死亡。目前需要制定新策略以提高抗肿瘤治疗的疗效并减少副作用。因此,本研究旨在对光动力疗法(PDT)调节肿瘤微环境的能力以及PDT在鼻咽癌治疗中的疗效进行系统评价和荟萃分析。综述者进行了系统评价的所有步骤。检索了PubMed、Science Direct、Scopus、Scielo、Lilacs、EMBASE和Cochrane图书馆数据库。使用OHAT评估偏倚风险。采用随机效应模型进行荟萃分析(α = 0.05)。经PDT处理的鼻咽癌细胞显示,IL-8、IL-1α、IL-1β、LC3BI、LC3BII、MMP2和MMP9水平显著高于未接受PDT的组。PDT组中NF-κB、miR BART 1-5p、BART 16和BART 17-5p水平显著低于对照组。PDT后,感染EBV的鼻咽癌细胞的凋亡水平和活力(>70%)有效。与对照组相比,该治疗还提高了LMP1水平(0.28 - 0.50/<0.05)。PDT在杀死感染EBV的鼻咽癌细胞和调节肿瘤微环境方面显示出有前景的疗效结果。应进行进一步的临床前研究以验证这些结果。
