Prevalence of cancer in Danish patients referred to a fast-track diagnostic pathway is substantial.

INTRODUCTION

Danish patients diagnosed with cancer who present with unspecific signs and symptoms are diagnosed with unfavourable delay, which has led to the establishment of a national fast-track (cancer) pathway. The aim of this study was to estimate the prevalence of cancer and other diagnoses in patients referred to this programme at Aarhus University Hospital from general practitioners. Furthermore, we aimed to characterise the patient cohort, assess survival and estimate the predictive values of symptoms, signs and biochemical abnormalities.

METHODS

From 1 March 2011 to 31 December 2013, data of interest were consecutively collected from the electronic patient record by two medical doctors.

RESULTS

Overall, 18% (58/323) had cancer, but the prevalence decreased from 22% in 2011 to 16% in 2013. Haematological cancers and cancers originating from the digestive system were the predominant cancer diagnoses. Patients diagnosed with cancer unfortunately had a high mortality suggesting that we diagnose cancer in the late, non-curable stages. Patients referred to the fast-track pathway had a median of four symptoms, most commonly weight loss and fatigue. In one fourth of the patients, a final diagnosis was not reached at discharge. For the rest (n = 185), gastrointestinal conditions, infectious and rheumatological diseases were most common. The predictive value of the presenting symptoms was poor. Age and biochemical markers considered as unspecific markers of cancer were better predictors. Anaemia was seen in 71% versus 34% of patients with/without diagnosed cancer, respectively.

CONCLUSIONS

Unspecific signs and symptoms that may be indicative of cancer represent a clinical challenge. A fast-track (cancer) pathway is a new option for patients not entitled to enter an organ-specific programme.
