It is common knowledge that apparently similar tumors often show different responses to therapy. This experience has generated the idea that histologically similar tumors could have biologically distinct behaviour. The development of effective therapy therefore, has the explicit challenge of understanding biological behaviour of a tumor. The question is which parameters in a tumor could relate to its biological behaviour ? It is now recognised that the development of malignancy requires an alteration in the program of terminal differentiation in addition to aberrant growth control. In this study therefore, ultrastructural markers that relate to defective terminal differentiation and possibly invasive potential of cells have been identified in human oral leukoplakias, erythroleukoplakias and squamous cell carcinomas of the tongue.

Objectives: Many studies have examined the prognostic significance of the neutrophil-to-lymphocyte ratio (NLR) in oral cancer; however, the results are contradictory. We, therefore, conducted a meta-analysis aiming to clarify the prognostic value of the NLR in oral cancer patients. Methods: A literature search was conducted in the PubMed, Web of Science, and Embase databases. Stata version 12.0 was used for statistical analysis. Results: A total of 14 studies with 3216 patients were finally included. The results indicated that a high NLR was significantly associated with worse DFS (n=10, HR = 1.73, 95% confidence interval [CI] = 1.44–2.07, P<0.001). Similar results were observed for overall survival (OS) (n=9, HR = 1.61, 95% CI = 1.39–1.86, P<0.001). Moreover, a high NLR was also correlated with lymph node metastasis (n=7, odds ratio [OR] = 1.62, 95% CI = 1.32–1.98, P<0.001), advanced tumor stage (n=7, OR = 2.63, 95% CI = 2.12–3.25, P<0.001), T stage (n=6, OR = 3.22, 95% CI = 2.59–4.01, P<0.001), tumor differentiation (n=5, OR = 1.48, 95% CI = 1.03–2.11, P=0.033), and perineural invasion (n=4, OR = 1.83, 95% CI = 1.4–2.39, P<0.001). However, an elevated NLR was not correlated with gender. Conclusion: This meta-analysis showed that the NLR might be a potential independent prognostic factor in patients with oral cancer.

PURPOSE This study investigated the frequency of the expression and prognostic significance of a panel of immunocytochemical markers in resected non-small-cell lung cancer (NSCLC). PATIENTS AND METHODS A total of 515 cases of pathologic stage I NSCLC were analyzed. The median follow-up time of surviving patients was 102 months. The following immunocytochemical markers were tested: blood group A and precursors of blood antigens; laminin receptor; c-erbB1/epidermal growth factor receptor (EGFR) and c-erbB2/Neu; BCl2; p53; and angiogenesis. Kaplan-Meier estimates of survival and time to recurrence were calculated for clinical variables and biologic markers using the Cox model for multivariate analysis. RESULTS The pathologic tumor extension (pT) represented the most powerful prognostic factor for survival (P = .0008) and time to recurrence (P = .0007). None of the immunocytochemical markers emerged as an independent predictive factor for survival. Bcl2-positive tumors showed a better time to recurrence (P = .03), but the difference lost statistical significance in the multivariate analysis. Of interest, in the group of 137 patients classified as pT1N0, both EGFR expression and nonangiogenic type of vascular pattern were associated with a poorer survival (P = .02). However, data derived from subset analysis must be interpreted cautiously. CONCLUSION Our findings do not support a relevant prognostic role of immunocytochemical markers in NSCLC. The evidence is not sufficient to alter clinical practice or even to restrict clinical trials of adjuvant treatments to predefined biologic subsets of patients.
