Prognostic value of baseline hemoglobin-to-red blood cell distribution width ratio in small cell lung cancer: A retrospective analysis.

The prognostic value of the baseline hemoglobin-to-red blood cell distribution width ratio was evaluated in patients with small cell lung cancer. In this population, this ratio was an independent predictor of overall survival and progression-free survival. This ratio, an inexpensive and routine parameter, can be used as a prognostic factor in small cell lung cancer.
