In “Pretreatment Characteristics of Carcinoid Tumors of the Lung Which Predict Aggressive Behavior” published in the American Journal of Clinical Oncology, 20(3), 285-288, June 1997, there are two corrections.

1. Incorrect P-Value Cited in Abstract

The abstract on page 285 cited an incorrect p-value:

“Five-year survival was 38.7% for patients with “atypical” histopathology as compared with 78.9% for patients with “typical” histopathology (p=0.01).”

A p-value, for this analysis, was not cited in the Results section. The analysis was performed on a subset of patients with tumor blocks available for review (n=63). The p-value error insertion in the abstract could have occurred during typesetting since the same p-value was cited in the preceding sentence, in the abstract, for a separate analysis.

2. Incorrect Study Population Cited in Discussion

The Discussion section on page 288, paragraph 3, cited a statistical analysis for 95 patients.

The analysis does not apply to the final study population. The study focus was 79 patients. Tumor blocks were available for 63 of the 79 patients.

The corrected sentence is:

Among the 63 patients with tumor blocks reviewed, 5-year survival was 38.7% for 14 patients with atypical carcinoid tumors as compared with 78.9% for 49 patients with typical carcinoid tumors.
