Nasopharyngeal carcinoma (NPC) is a major public health
problem in Hong Kong with an annual incidence of 15.4/100,000.
About 180 new cases are seen and treated each year in
our department. All patients are subjected to a uniform
staging protocol, and the aggressive radiotherapy (RT)
technique used has resulted in the highest loco-regional
control rate in the region. In patients with loco-regionally
advanced disease on presentation, the rate of subsequent
distant metastasis is high. In these patients the use
of a multi-modality approach has been extensively investigated
in our center. The publications of these trials have
made significant impact on standard treatment approach
for these patients. Patients with the most loco-regionally
advanced disease on presentation have an improved outcome
with concurrent chemotherapy-radiotherapy compared with
radiotherapy alone. For patients with loco-regionally
recurrent and/or distant metastatic disease, encouraging
results of several Phase II chemotherapy trials and
translational studies have led to the initiation by
the group of a multicenter prospective trial using chemotherapy
and specific targeting agent against Epidermal Growth
Factor Receptor (EGFR). The Epstein-Barr virus (EBV)
is consistently associated with NPC. In collaboration
with the Johns Hopkins Oncology Center and the University
of Birmingham CRC Institute of Cancer Studies, with
funding from the National Cancer Institute (USA) and
the Cancer Research Campaign (UK), we have initiated
trials of novel immunotherapeutic approaches in the
treatment of patients with NPC. The first of these has
been completed and preliminary results have been reported.
