Hyperbaric oxygen therapy (HBOT), has gained attention in recent years as a potential adjunct to conventional cancer treatments, particularly addressing tumor hypoxia which is extensively employed post-injury treatment, the administration of >92% at 1.5- 3.0 ATA for 60-120 minutes. HBOT attributed least five mechanisms including epigenetic regulation gene expression, mechanical effects, bacteriostatic hyperoxygenation carbon monoxide and cyanide poisoning restoration from hypoxia. emerging promising overcoming hypoxia—a key feature microenvironment (TME) that drives growth, resistance, metastasis. By delivering high concentrations under pressure, improves tissue oxygenation, potentially suppressing reducing hypoxia-induced enhancing efficacy chemotherapy radiotherapy. Studies have shown its anti-angiogenic effects some models ability alkalize TME. In prostate cancer, demonstrated slowing growth increasing treatment sensitivity cell lines like DU-145 LNCaP.

The distinct tumor microenvironment (TME) of prostate cancer (PCa), which promotes proliferation and progression, consists various stromal cells, immune a dense extracellular matrix (ECM). understanding the TME extends to tertiary lymphoid structures (TLSs) metastasis niches provide more concise comprehension metastasis. These constituents collectively structure hallmarks pro-tumor TME, including immunosuppressive, acidic, hypoxic niches, neuronal innervation, metabolic rewiring. In combination with knowledge advancement emerging therapeutic technologies, several strategies have been developed, some them tested in clinical trials. This review elaborates on PCa components, summarizes TME-targeted therapies, provides insights into carcinogenesis, strategies.

Immunotherapy targeting the PD-1-PD-L1 axis yielded good results in treating different immunologically ''hot'' tumors. A phase II study revealed therapeutic activity of pembrolizumab selected prostatic carcinoma (PC)-patients. We performed a systematic literature review (PRISMA guidelines), which analyzes immunohistochemical expression PD-L1 human PC samples and highlights pre-analytical interpretation variables. Interestingly, 29% acinar PCs, 7% ductal 46% neuroendocrine carcinomas/tumors were PD-L1+ on immunohistochemistry. Different scoring methods or cut-off criteria applied variable specimen-types, evaluating tumors showing clinic-pathologic features. The positivity rate antibody clones tumor cells ranged from 3% (SP142) to 50% (ABM4E54), excluding single case tested for RM-320. most clone was E1L3N, followed by 22C3 (most used eligibility), SP263, SP142, 28-8, gave rates 35%, 11-41% (depending systems), 6%, 3%, 15%, respectively. Other <200 cases. usually higher than benign tissues. It non-tissue microarray specimens (41-50% vs. 15%), as frequently showed heterogenous focal PD-L1-staining. expressed immune stromal 12% 69% cases, Tumor heterogeneity, inter-institutional preanalytics, inter-observer variability may account result biases.

Gastric cancer (GC) is a malignant tumor that originates from the epithelium of gastric mucosa and has poor prognosis. Stomach adenocarcinoma (STAD) covers 95% total cancer. This study aimed to identify prognostic value RNA methylation-related genes in In this study, The Cancer Genome Atlas (TCGA)-STAD GSE84426 cohorts were downloaded public databases. Patients classified by consistent cluster analysis based on prognosis-related differentially expressed methylation Prognostic obtained differential expression, univariate Cox least absolute shrinkage selection operator (LASSO) analyses. model was established validated training set, test set validation respectively.

Aberrant glycosylation in tumour progression is currently a topic of main interest. Tumour-associated carbohydrate antigens (TACAs) are expressed wide variety epithelial cancers, being both diagnostic tool and potential treatment target, as they have impact on patient outcome disease progression. Glycans affect tumour-cell biology properties well the antitumor immune response. It has been ascertained that TACAs cell migration, invasion metastatic when by cancer cells or their extracellular vesicles. On other hand, tumour-associated glycans recognized C-type lectin receptors possess immunomodulatory which enable growth response evasion. Yet, much remains unknown, concerning mechanisms involved deregulation glycan synthesis how this affects major level. This review summarises findings to date aberrant influence immunity, application spotlights unanswered challenges remaining be solved.

Prostate cancer remains a significant global health challenge, necessitating the development of novel therapeutic approaches. This study investigated potential Antrodia cinnamomea formula (XIANZHIFANG formula, XZF), comprising cinnamomea, Sanghuangporus sanghuang, Ganoderma lucidum, sinense, and Inonotus obliquus, in prostate treatment. HPLC analysis confirmed presence key triterpenoids, including Antcin A, B, C, K, Zhankuic acid 4,7-dimethoxy-5-methyl-1,3-benzodioxole. Cytotoxicity assays demonstrated that XZF (50–200 μg/mL) exhibited selective activity, maintaining viability non-cancerous 293T-cells while enhancing activated CD8+ CD4+ T-cells dose-dependent manner. significantly reduced PD-1 expression but not inhibited PD-L1/PD-1 interaction, achieving 93% inhibition at 200 μg/mL. Furthermore, when combined with atezolizumab (1 μg/mL), complete blockade interaction. In cells, differential antiproliferative effects. PC-3 across concentration range 25–200 μg/mL, whereas DU145 cells showed only partial higher concentrations (100–200 μg/mL). LNCaP reduction viability, mirroring response pattern cells. Conditioned medium from XZF-treated macrophages, particularly human THP-1 suppressed migration Notably, conditioned stronger inhibitory effect on cell compared to murine RAW 264.7 macrophages. These findings indicate exerts its through multiple mechanisms, direct effects enhancement T-cell responses, modulation immune checkpoint pathways, macrophage-mediated suppression survival migration. The pronounced observed macrophage models suggest promising avenue for further investigation clinical settings, combination existing immunotherapies.
