Clinical significance of NQO1 polymorphism and expression of p53, SOD2, PARP1 in limited-stage small cell lung cancer.
Article in International journal of clinical and experimental pathology, 2014. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 papers.
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
backgroundSmall cell lung cancer (SCLC) is one of highly aggressive cancers with poor prognosis. Unfortunately, there are as yet no molecular targets that can be exploited to prolong survival in patients with SCLC. This study aimed to investigate possible molecular markers associated with prognosis in limited-stage small cell lung cancer (LS-SCLC).
methodsThe demographic and clinical data for LS-SCLC patients treated in a tertiary care hospital between January 2008 and December 2012 were retrospectively reviewed. NQO1 polymorphism and the expression of p53, SOD2, PARP1 were examined in biopsy specimens, and the factors affecting prognosis were identified.
results79 patients with LS-SCLC having available pathologic tissues were analyzed. 84.8% of them received both chemotherapy and radiotherapy. NQO1 polymorphism was detected in 60.0% (45/79; heterozygous in 26 patients, homozygous in 19 patients). Over-expression of p53, SOD2, PARP1 was seen in 45.6% (36/79), 38.0% (30/79) and 41.8% (33/79) of the patients, respectively. The univariate Cox proportional hazards model revealed that serum lactate dehydrogenase (LDH) levels and PARP1 expression were associated with disease progression. In the multivariate analysis, only PARP1 expression was a significant independent prognostic factor for progression-free survival (hazard ratio: 0.494; 95% CI, 0.267-0.913, P = 0.025).
conclusionsPARP1 expression is correlated with longer progression-free survival in LS-SCLC requiring further studies to clarify the precise role of PARP1 and the relevance of PARP1-targeted therapy.
