Abstract
Objective: The aim of the study was to analyze the time-to-diagnosis interval in patients with
Cushing's disease (CD) and acromegaly (AC), to assess factors that promote early disease
detection and to investigate the medical fields diagnosing the pathologies.
Methods: 33 CD and 52 AC patients operated over 10 years received a self-designed disease-related
questionnaire. Data about symptoms and their duration prior to diagnosis, education
level, age, gender and place of residence (i. e. rural vs. urban, size of the city)
were collected.
Results: The mean time-to-diagnosis interval was 6.0 years in CD and 5.8 years in AC patients.
The vast majority of 67% of all investigated patients was diagnosed after they changed
their primary health care provider or during a hospital stay owing to comorbidities
caused by their underlying disease. Only 33% of all cases were diagnosed by their
primary physician. In both groups neither gender, age, place of residence, education
level, typical comorbidities (e. g. hypertension or diabetes) nor distinctive symptoms
and bodily changes of the underlying disease (e. g. prognathism, acral enlargement,
weight gain, buffalo hump) were significant factors promoting early detection.
Conclusions: Apparently, patient-related factors do not affect the time-to-diagnosis interval,
but rather the change of the primary health care provider. Knowledge of the disease
among physicians is prerequisite to early detection. Due to the deleterious sequelae
of delayed diagnosis, information programmes in the medical community are of paramount
importance. Institution of screening programmes should be evaluated.
