Vasculogenic mimicry (VM) is an intratumoral microcirculation pattern formed by aggressive cancer cells, which mediates tumor growth. In this study, we compiled the evidence from studies evaluating whether positive VM status can serve as a prognostic factor to patients with squamous cell carcinoma of the head and neck (HNSCC) or esophagus (ESCC). Comprehensive systematic searches were conducted using Cochrane Library, Ovid Medline, PubMed, and Scopus databases. We appraised the quality of studies and the potential for bias, and performed random-effect meta-analysis to assess the prognostic impact of VM on the overall survival (OS). Seven studies with 990 patients were eligible, where VM was detected in 34.24% of patients. Positive-VM was strongly associated with poor OS (hazard ratio = 0.50; 95% confidence interval: 0.38–0.64), which remained consistent following the subgroup analysis of the studies. Furthermore, VM was associated with more metastasis to local lymph nodes and more advanced stages of HNSCC and ESCC. In conclusion, this study provides clear evidence showing that VM could serve as a promising prognosticator for patients with either HNSCC or ESCC. Further studies are warranted to assess how VM can be implemented as a reliable staging element in clinical practice and whether it could provide a new target for therapeutic intervention.

Abstract Background: Epidemiologic studies have demonstrated that X-ray repair cross-complementary group 1 (XRCC1) is one of the susceptibility factors in head and neck squamous cell carcinoma(HNSCC) patients. However, its clinical prognostic impact remains controversial. Thus, a meta-analysis was performed to clarify the survival value of XRCC1 in HNSCC patients.Methods: Following the Preferred Reporting Items or Systematic Reviews Meta Analyses (PRISMA) 2020 guidelines, literature searches were systematically performed by PubMed, EMBASE and Web of Science with a manual retreive to evaluate the prognostic consequence of XRCC1 in HNSCC patients. Hazard ratios (HRs) and 95% confidence intervals (CIs) were collected to estimate the correlation between XRCC1 and the survival outcomes of HNSCC patients.Results: Ten studies including 2086 HNSCC patients who satisfied the inclusion and exclusion criteria were included in this meta-analysis. The meta-analysis showed that high XRCC1 expression and Arg399Gln and Arg194Trp were significantly correlated with poorer overall survival (OS), with HRs of 1.97 (95% CI, 1.36–2.84, P<0.001), 1.30 (95% CI, 1.12–1.51, P<0.001), and 1.65 (95% CI, 1.18–2.32 P<0.05), respectively.Conclusion: XRCC1 was associated with poorer survival outcomes in HNSCC patients. Hence, XRCC1 is a potential therapeutic target for HNSCC.

Diagnostic Efficacy

Human papillomavirus (HPV) is a risk factor for squamous cell carcinoma of the head and neck (HNSCC). This study aimed to investigate the feasibility of IHC- p16INK4a (p16) as an alternative modality for diagnosing HPV infection. We searched PubMed, EMBASE, Web of Science, and Cochrane library for studies that evaluated the diagnostic accuracy of IHC-p16 staining. A total of 30 studies involving 2,963 patients were included from 2007 to 2019. The combined sensitivity was 0.94 (95% CI: 0.92–0.95); specificity, 0.90 (95% CI: 0.89–0.91); positive likelihood ratio (LR), 6.80 (95% CI: 5.63–8.21); negative LR, 0.10 (95% CI: 0.07–0.16); diagnostic odds ratio, 85.98 (95% CI: 55.57–133.03); and area under the curve value, 0.9550. Subgroup analysis showed that the IHC-p16 test was more consistent with the in situ hybridization (ISH) test and has greater diagnostic value for oropharyngeal squamous cell carcinoma. The diagnostic efficacy of IHC-p16 varied among countries. In conclusion, IHC-p16 has high sensitivity and specificity for diagnosing HPV infection in HNSCC. The consistency of IHC-p16 findings with those of ISH indicate that their combination can be used to improve the specificity of diagnosis.

The prognostic value of microvessel density (MVD) in head and neck squamous cell carcinoma (HNSCC) remains disputable. The purpose of this study was to comprehensively determine the prognostic value of MVD in HNSCC. Relevant literatures were identified using PubMed, Embase, and Cochrane Library. A meta-analysis was performed to clarify the prognostic role of MVD in HNSCC patients and different subgroups. A total of 14 eligible articles were included in this meta-analysis. The combined hazard ratio (HR) and 95% confidence interval (95% CI) for overall survival (OS) of 11 studies was 1.663 (1.236-2.237, P = 0.001 ), and the pooled HR and 95% CI for progression-free survival (PFS) of 7 studies was 2.069 (1.281-3.343, P = 0.003 ). Subgroup analyses were also performed on different issues, such as regional distribution of patients, age, tumor location, antibody, and treatment strategy. To conclude, high MVD is associated with worse OS and PFS in patients with HNSCC.

Abstract Background The most important prognostic factor in squamous cell carcinoma of the head and neck (HNSCC) is the presence or absence of clinically involved neck nodes. The presence of metastases in a lymph node is said to reduce the 5-years survival rate by about 50%. The appropriate diagnosis of the presence of metastatic node is very important for the management of HNSCC Aim To compare difTerent diagnostic modalities for assessment of the clinically non palpable lymph nodes in HNSCC including by meta-analysis: CT, MRI, US, USFNAC and PET/CT for the proper cervical lymph node staging. Methods Met-analysis study on patients with HNSCC of clinically non palpable lymph nodes (cN0). Results Analysis was divided in 6 groups .Each group contain analysis of one modality according to available studies per patient, per level and per lesion .US is fair test per patient and per lesion.CT is good test per patient and excellent test per lesion.MRI is poor test per patient and fair test per lesion.CT-MRl combined is fair per patient and excellent per level.PET/CT is good per patient, fair per lesion and excellent per level. USFNAC is excellent per lesion. Conclusion CT, CT-MRI combined, PET/CT and USFNAC proved to be excellent in detecting cN0.MRI was poor test in detecting cN0.US was a fair test in detecting cN0 if used alone.
