The prognostic significance of race and survival from laryngeal carcinoma.

摘要: Surveillance, Epidemiology, and End Results (SEER) program data suggest that blacks with laryngeal carcinoma have a significantly lower 5-year survival rate than whites. Most of this difference persists despite adjustment for "crude stage." To evaluate possible factors contributing to residual deficit, 190 white 23 black patients treated at the Martinez Veterans Administration Hospital between 1968 1988 were studied. The independent impact race on was analyzed respect various prognostic including treatment delay, elapsed time (diagnosis treatment), age, stage, cancer subsites, type therapy. No significance could be attributed race. differences noted in SEER probably reflect tendency use crude stage underestimate groups within categories "local" "regional" disease, subsites (glottic versus supraglottic), variable distribution these different populations. This study suggests when subsite, quality care are adequately considered, from is comparable
