New P16 Expression Criteria Predict Lymph Node Metastasis in Patients With Non-small Cell Lung Cancer.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundThere have been many attempts to predict the prognosis of lung cancer based on the expression patterns of P16 protein, but with limited success. The Eighth American Joint Committee on Cancer (AJCC) for head and neck cancer recently developed new criteria for evaluating P16 expression. Here, we applied these new criteria to evaluate the prognosis of non-small cell lung cancer (NSCLC). MATERIALS AND
methodsA total of 148 patients who had undergone surgery for NSCLC were enrolled in the study. P16 protein expression patterns from NSCLC tissue microarray samples were examined by immunohistochemical analysis. The Eighth AJCC head and neck cancer staging criteria were used to evaluate positive P16 expression (moderate/strong nuclear expression intensity and distribution >75% cells) in NSCLC. The relationship between P16 expression and clinicopathological factors were evaluated and survival analysis was included.
resultsNegative P16 expression was significantly associated with NSCLC with lymph node metastasis (p=0.025). In addition, patients with NSCLC with negative P16 expression demonstrated poor disease-free and disease-specific survival in multivariate analysis. The Kaplan-Meier survival curve confirmed that negative P16 expression was significantly correlated with a poor disease-free survival (p=0.017) and disease-specific survival (p=0.016).
conclusionP16 expression defined with the new AJCC criteria is useful for detecting lymph node metastasis in NSCLC.
