Our study supports the view that a high basal PLR is a poor prognostic factor in NSCLC. However, the validity of the cut-off values for PLR identified in our study needs further prospective trials.

Aim of the studyData are available indicating that red blood cell distribution width (RDW) is higher in cancer patients compared to healthy individuals or benign events. In our study, we aimed to investigate the influence of different RDW levels on survival in lung cancer patients.Material and methodsClinical and laboratory data from 146 patients with lung cancer and 40 healthy subjects were retrospectively studied. RDW was recorded before the application of any treatment. Patients were categorised according to four different RDW cut-off values (median RDW, RDW determined by ROC curve analysis, the upper limit at the automatic blood count device, and RDW cut of value which used in previous studies). Kaplan-Meier survival analysis was used to examine the effect of RDW on survival for each cut-off level.ResultsThe median age of patients was 56.5 years (range: 26–83 years). The difference in median RDW between patients and the control group was statistically significant (14.0 and 13.8, respectively, p = 0.04). There was no difference with regard to overall survival when patients with RDW ≥ 14.0 were compared to those with RDW < 14.0 (p = 0.70); however, overall survival was 3.0 months shorter in low values of its own group in each of the following cut-off values: ≥ 14.2 (p = 0.34), ≥ 14.5 (p = 0.25), ≥ 15 (p = 0.59), although no results were statistically significant.DiscussionWe consider that the difference between low and high RDW values according to certain cut-off values may reflect the statistics of larger studies although there is a statistically negative correlation between RDW level and survival.

In patients with CRC, the time duration of relapse after completion of the operation and adjuvant chemotherapy was a prognostic factor. Grade I and superficial tumors (T1-T2) are the predictors of late relapses (after >24 months). The patients relapsed within the first 24 months after primary therapy had poor prognosis compared to those who relapsed in late period.
