Delay by patients and doctors in treatment of Pancoast tumor.

PURPOSE

Long delays in diagnosis and treatment of Pancoast tumor have been reported but the reasons for these delays have yet to be fully considered. The aim of this study was to assess recent delays in diagnosis and treatment of Pancoast tumor and to determine the reasons for the delays.

PATIENTS AND METHODS

We identified Pancoast tumors in patients with lung cancer referred to the radiation department of a city hospital between September 1999 and August 2004. From interviews conducted by a radiation oncologist and review of the medical records, delay due to a patient was calculated as the interval between the onset of symptoms and presentation to a physician, and delay due to a doctor as the interval between the presentation and the definitive treatment. The overall treatment delay was calculated as the sum of those delays. Radiological workups were also reviewed for errors, and the effect of any errors on the delays was estimated.

RESULTS

The study population included 42 men and six women with a median age of 65.5 years at presentation. Treatment delay ranged widely from 38 to 400 days (mean 164.0): delay due to patients ranged from 0 to 371 days (mean 55.8), accounting for 34% of the mean treatment delay; delay due to doctors ranged from 14 to 349 days (mean 108.2), and accounted for the remaining (66%) mean treatment delay. In 166 radiological studies reviewed, 98 radiological errors (59%) were identified in 28 patients (58%). These patients waited an additional mean of 88.4 days for correct radiological interpretation, accounting for 48% of the mean doctors' delay. Thus, the mean doctors' delay with radiological errors was significantly longer than that without radiological errors (p < 0.05).

CONCLUSIONS

Treatment delay for Pancoast tumor was relatively long, and approximately two-thirds of the delay was due to doctors, mainly because of errors in radiology.
