Abstract

Purpose: The major value of prognostic markers in potentially curable non-small cell lung cancer (NSCLC) should be to guide therapy after surgical resection. In this regard, the patients' immune status at the time of resection may be important and also measurable. The immune system has paradoxical roles during cancer development. However, the prognostic significance of tumor-infiltrating lymphocytes is controversial. The aim of this study is to elucidate the prognostic significance of epithelial and stromal lymphocyte infiltration in NSCLC. Experimental Design: Tissue microarrays from 335 resected NSCLC, stage I to IIIA were constructed from duplicate cores of viable and representative neoplastic epithelial and stromal areas. Immunohistochemistry was used to evaluate the epithelial and stromal CD4+, CD8+, and CD20+ lymphocytes. Results: In univariate analyses, increasing numbers of epithelial CD8+ (P = 0.023), stromal CD8+ (P = 0.002), epithelial CD20+ (P = 0.023), stromal CD20+ (P < 0.001), and stromal CD4+ (P < 0.001) lymphocytes correlated significantly with an improved disease-specific survival. No such relation was noted for epithelial CD4+ cells. Furthermore, a low level of stromal CD8+ lymphocyte infiltration was associated with an increased incidence of angiolymphatic invasion (P = 0.032). In multivariate analyses, a high number of stromal CD8+ (P = 0.043) and CD4+ (P = 0.002) cells were independent positive prognostic factors for disease-specific survival. Conclusions: High densities of CD4+ and CD8+ lymphocytes in the stroma are independent positive prognostic indicators for resected NSCLC patients. This may suggest that these cells are mediating a strong antitumor immune response in NSCLC.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
