[Delays in the diagnosis of lung cancer].
OBJECTIVE
To study the clinical and demographic factors associated with delays in the diagnosis of lung cancer.


METHODS
A 2-year prospective study of patients admitted to the respiratory medicine ward with a suspected diagnosis of lung cancer. We studied demographic factors, health care received, place of residence, and delays in carrying out diagnostic procedures. The following diagnostic time periods were defined: consultation (from first symptom to first medical visit), middle period (from first medical visit to hospital admission) and diagnostic (from hospital admission to histological diagnosis and clinical staging).


RESULTS
One hundred thirteen patients with a mean age of 65 years (range, 36-90), 103 men and 10 women, were studied. The most frequent symptoms leading to consultation were coughing (10.6%), hemoptysis (19.5%), chest pain (26.5%), and shortness of breath (9.7%). First visits were to a primary care physician for 72%, to the hospital emergency room for 22%, or to a pulmonologist for 6%. Forty-four percent of the patients visited the doctor 2 or 3 times. The mean SD, numbers of days for the different time periods were as follows: consultation, 30.3 60; diagnosis, 18.6 19; middle period 37.9 63. The mean total time from first symptom to diagnosis was 85.7 87 days. The middle period, the time in hospital until diagnosis, and the total time were shorter when patients were referred by the primary care physician to the emergency room or were directly admitted to the hospital (P<.001). Only 25.7% of the staged lung cancers were operable.


CONCLUSIONS
Delays in lung cancer diagnosis are long. The attitudes of primary care physicians and their relations with specialized care providers are crucial for reducing delays.
