New Scoring System Available at Home Health Care for Prediction of 14 Days Survival in Lung Cancer Complicated with Lymphangitic Carcinomatosis

Abstract

Objective: Patients with lung cancer often greeted their terminal phase in the treatment at home, and many cases complicated with lymphangitic carcinomatosis took a sudden turn. The aim of the present study was to determine a scoring system available at home health care for prediction of short-term survival of lung cancer complicated with lymphangitic carcinomatosis. Methods: In 14 lung cancer patients with lymphangitic carcinomatosis in our medical care at home, we determined significant close correlated and independent factors for assuming death during 14 days by logisticregression analysis, and made out new scoring system. Moreover, we determined cut-off value on receiveroperating characteristics analysis. Results: In our scoring system calculated as the summation points awarded for the presence of 5 parameters (i.e., systolic blood pressure 100 beats/minute, 3 point; blood oxygen saturation 2 L/minute, 2 point; respiratory frequency>20 times/minute, 3 point), cut-off value was 8 (sensitivity 90%, specificity 68%). Conclusions: We made a new a scoring system available at home health care for prediction of 14 days survival of lung cancer complicated with lymphangitic carcinomatosis assumed systolic blood pressure, pulse rate, respiratory frequency, blood oxygen saturation, and oxygen dose.
