Nasopharyngeal Carcinoma Treatment Treatment depends upon the location of the NPC and the stage at which the tumour is at. Stage 1 and 2 NPCs may be treated with a combination of Radiotherapy and Surgery while Stage 3 and 4 are more likely to need Chemotherapy, Radiotherapy and Surgery. The commonest form of treatment for NPCs is Radiotherapy. It can be applied externally or inserted into the tumour in radioactive beads (Brachytherapy). Courses of Radiotherapy given over a number of weeks may make the tumour recede entirely or at least shrink the tumour to a size which can be surgically removed easily. Surgery is typically the second line therapy for NPCs. A well localised tumour may be easily removed but an invasive tumour can take numerous hours of delicate surgery to remove. Chemotherapy is typically prescribed in either tablet or IV forms. Recent advances in Chemotherapeutics have revealed than the Immune Modulator Interferon Beta, is relatively effective at treating NPC.

Unformatted text preview: Irradiation and surgery at other sites within the head and neck may also be needed to treat secondary disease. Prognosis Recovery depends upon the location, size, stage and receptiveness to treatment of the tumour. Small stage 1 tumours are highly curable with 80-90% of patients still alive at 5 years. Moderately advanced (stage 2) tumours are also curable with survival rates around 50-75%. Advanced tumours involving bone and nerve destruction are poorly controlled with radiation with or without surgery. In people with advanced tumours the condition is typically fatal within 6 months. Most recurrences occur within the first five years following initial diagnosis. Prevention Since the cause of NPC isn’t fully understood it is difficult to establish how it may be prevented. Regular follow ups post-treatment are vitally important as recurrence can occur. Follow ups include regular head, neck and chest CT scans and blood tests looking for evidence of recurrence....
