Table 1 Diagnostic and prognostic value of cytokines in gastric cancer
Cytokine | Change in GC vs control | Diagnostic performance | Therapeutic/prognostic notes | Ref. | |
IL-1β | Increased in GC | AUC = 0.7; sensitivity approximately 0.76, specificity approximately 0.43 | Central in Helicobacter pylori-driven inflammation; blocking IL-1β (e.g., canakinumab) is feasible; associated with tumor invasiveness and poor prognosis | Ren et al[1], Sánchez-Zauco et al[5] | |
IL-6 | Increased in GC | AUC = 0.72; meta analysis: Sensitivity 0.80, specificity 0.86, AUC = 0.90 | Potent growth and survival factor via Janus kinase/signal transducer and activator of transcription 3; high IL-6 predicts worse survival and chemoresistance | Ren et al[1], Kai et al[9], Janiczek-Polewska et al[10], Wang et al[12], Laurino et al[14] | |
IL-8 | Increased in GC | AUC = 0.78; evidence mixed (some studies report no difference) | Promotes angiogenesis/metastasis; IL-8/CXC chemokine receptor 1 and 2 inhibitors reverse platinum resistance in preclinical GC models; rising IL-8 after treatment predicts chemoresistance | Ren et al[1], Liu et al[13], Jiang et al[15], Limpakan Yamada et al[16] | |
IFN-γ | Increased in GC | AUC = 0.65 (below 0.7) | Key T-cell cytokine; might reflect immune activation rather than tumor presence; Sánchez-Zauco et al[5] found it up in early GC; role in immunotherapy contexts | Ren et al[1], Sánchez-Zauco et al[5] | |
Multi-cytokine panel (IL-1β + IL-6 + IFN-γ) | Increased in GC | AUC = 0.888 | Best diagnostic performance; synergistic detection | Ren et al[1] |
Table 2 Selected inflammation-related biomarkers in gastric cancer
Biomarker | Function (immune role) | Diagnostic (AUC, sens/spec) | Stage association | Therapy relevance | Ref. |
IL-1β | Pro-inflammatory, fever response; promotes tumor inflammation | AUC > 0.7 for GC | Increased with higher T/N stage | Not specific | Ren et al[1], Sánchez-Zauco et al[5] |
IL-6 | Pro-inflammatory, growth factor; STAT3 activator | AUC > 0.7; specificity approximately 97%, sensitivity approximately 39% | Increased with T/N stage; Increased in metastasis | Drives cisplatin resistance; targetable by anti-IL-6R therapy | Ren et al[1], Sánchez-Zauco et al[5], Wang et al[12], Thong-Ngam et al[21] |
IL-8 (CXCL8) | Chemokine, neutrophil attractant; angiogenesis | AUC > 0.7 | Likely increased in advanced/invasive GC (Helicobacter pylori linked) | Promotes metastasis; CXC chemokine receptor 1 and 2 inhibitors in trials | Ren et al[1] |
IFN-γ | Th1 cytokine, anti-tumor effector | Increased in GC | Data limited | Reflects T-cell response; immunotherapy marker | Ren et al[1], Sánchez-Zauco et al[5] |
IL-10 | Anti-inflammatory, immunosuppressive (Tregs) | Low diagnostic yield alone | Increased in advanced disease, poor prognosis | Immunosuppressive tumor microenvironment; high IL-10 may predict poor ICI response | Szaflarska et al[19] |
IL-11 | IL-6 family, gp130/STAT3 activator (epithelial mitogen) | Not established for screening | Increased tumor/mucosal expression with stage | Mediates chemoresistance; anti-IL-11Rα agents under study | Necula et al[20] |
IL-18 | IFN-γ–inducer, Th1 cytokine | Sensitivity approximately 52.2%, specificity approximately 83.3% at 40 pg/mL | Likely increased with tumor burden | May potentiate immunotherapy via IFN-γ; possible adjuvant target | Thong-Ngam et al[21] |
IL-24 (melanoma differentiation-associated gene-7) | Tumor-suppressor cytokine, induces cancer apoptosis | Investigational | Declined in tumors (anti-tumor effects) | Gene therapy for radiosensitization (preclinical) | Mao et al[22] |
MIG (CXCL9) | T-cell chemoattractant (IFN-inducible) | Not used diagnostically | Increased in advanced GC | May predict T-cell infiltration; synergizes with checkpoint blockade | Baj-Krzyworzeka et al[23] |
Macrophage inflammatory protein-1β (C-C motif ligands 4) | Monocyte/T-cell chemoattractant | Not used diagnostically | Increased in GC vs control (stage-independent) | May reflect myeloid infiltration | Baj-Krzyworzeka et al[23] |
SIL-2Rα (CD25) | Marker of T-cell activation/regulation | Measured as immune activation index | Increased in advanced disease (likely) | Elevated by Tregs; may guide IL-2 or ICI therapy | Muhammad et al[25], Nakata et al[26], Park et al[28] |
IL-6 rs1800796 (gene) | Promoter SNP (G/C) affecting IL-6 Levels | Not diagnostic | Not staging, but risk factor | High-risk allele may inform surveillance | Wang et al[29], Wang et al[27] |
IL-8 rs4073 (gene) | Promoter SNP (T/A) affecting IL-8 Levels | Not diagnostic | Risk variant in Asians | Carriers may benefit from chemokine-targeted approaches | Wang et al[29] |
