Abstract

BACKGROUND: Extracellular signal‐regulated kinase (ERK) promotes proliferation, metastasis, and poor survival in cancers of the breast, lung, and liver. Advanced localized renal cell carcinoma (RCC) is extraordinarily treatment resistant and has high recurrence rates despite surgery. Limited data exist regarding the prognostic significance of activated (phosphorylated) ERK in RCC. The authors hypothesized that activated ERK (pERK) promotes disease progression and metastasis in localized RCC and may be of value as a biomarker to predict disease recurrence. METHODS: The expression profile of pERK was examined by immunocytochemistry using a tissue microarray constructed from 174 drug treatment–naive patients who had undergone radical nephrectomy for localized RCC. Levels of tumor‐cell specific pERK were scored and correlated with clinicopathologic parameters of RCC and disease‐free survival. RESULTS: Immunostaining for pERK was present in 36% of all RCCs, with a predominance found in the clear cell histologic subtype. High expression was associated with increased tumor size, increased TNM stage, and vascular invasion. Patients with pERK‐positive tumors had a mean disease‐free survival of 4.19 years, compared with 6.38 years for patients with pERK‐negative tumors (P < .001). Cox regression models revealed pERK to be a significant independent predictor of disease‐free survival, with a hazards score of 2.9 (P < .001), a value similar to tumor grade (hazards ratio, 3.01; P < .001). CONCLUSIONS: Expression of pERK is an independent prognostic factor in RCC that is associated with advanced and aggressive pathologic features of renal tumors and predicts the onset of metastasis in patients with localized disease.

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.
