Abstract: |
Nasopharyngeal cancer is a common disease in our locality. The primary treatment modality is radiation and concurrent chemotherapy. In a small number of patients the tumour unfortunately recurs after this combined mortality of treatment. The surgical salvage is now possible with the maxillary swing approach nasopharyngectomy. We however, are not sure of the exact infiltrative pattern at the primary site of these recurrent nasopharyngeal cancer. The aim of the project is to study the pattern of tumour extension in the nasopharynx; whether it involves cartilage, the prevertebral muscle, and the skull base. It is known that recurrent tumour after radiation is difficult to diagnose and as it may be well located in submusocal region. We have collected over 50 specimens of nasopharyngectomy performed for recurrent nasopharyngeal cancer after chemoradiation. We plan to perform whole specimen section of these specimens so that, we can have a three-dimensional recognition of the pattern of tumour extension. This could greatly aid the planning of surgical savage. Molecular markers such as hypermethylated CpG rich locus can also be examined on these specimen to define exactly where the margin of resection are and whether further resection is possible to achieve a better surgical clearance. Most nasopharyngeal cancer tissues were obtained through biopsies and we have a unique collection of surgical specimen to allow this type of whole specimen section with histological examination as well as with molecular tests to be carried out. This will determine clearly the pattern of tumour extension of nasopharyngeal cancer after chemoradiation. |

Abstract: |
We will conduct head and neck surgery teaching course in different cities of China for 3 to 4 days annually. Senior surgeons and nurses from other cities and provinces in China would come and get acquainted with the latest developments in surgical technique and treatment plan. The knowledge they gained will help the poor and sick patients suffering from head and neck cancer in China. |
