Nasopharyngeal carcinoma: a delay in diagnosis.
One hundred consecutive newly diagnosed patients with nasopharyngeal carcinoma (NPC) since January 1994 were the subjects for studying various factors that contribute to the delay in the confirmation of the diagnosis. Seventy-nine of them were males and the peak age of incidence was the fifth decade. Ninety two percent were Chinese, 7% Malay and 1% Indian. Seventy six percent were agriculture workers or labourers with 66% having either no formal education (16%) or only primary level education (50%). In 50% of patients neck swelling was the first presenting symptom, 26% had nasal symptoms, 12% ear symptoms and 11% has symptoms due to intracranial extension of tumour. As many as 80% were at UICC Stage IV at the time of diagnosis. While the median delay, on the part of patients, in consulting a doctor was 2.5 days, the median delay on the part of the doctors to confirm the diagnosis of NPC was 127 days, the delays was particularly worse when the patients presented with ear symptoms (266 days) followed by those with neck swelling (94 days). For those patients who were required to undergo more than one nasopharyngoscopy and biopsy the median doctor's delay was 144 days. Since 82% of patient's had first consulted general practitioners, it is suggested that their level of awareness with regards to the diagnosis of NPC be significantly raised so that the delay on their part be greatly minimized.
