The team approach in the managemenit of oral cancer So far as the patient is concerned the clinician's approach should have two parallel aims. The first is toi determine and evaluate the patient's overall condition and to prepare him psychologically and physically for the treatment and its consequences. The other aim is to inform the patient to enable him to participate in his own way in the battle which he must fight with the help of his doctors for his own survival. No universally accepted policy in this matter has been adopted, but all studies have stressed that at some stage, at the discretion of the clinician in charge, the patient should have the right to participate in the decision-making and take, or at least share with the clinician, some of the responsibilities. The most important thing is for the clinician to prove to the patient that he is interested not only in his disease and its progress but also in the patient as an individual in his own right. It has been suggested that such discussion be left to the family doctor, who probably knows the patient and his family better (6). The individuals concerned in the management of a patient with oral cancer may be divided into two groups, one major or curative and the other minor or supportive. The major group will include the surgeon, the radiotherapist, the medical oncologist, and the pathologist. The minor group should include the general (family) physician and dentist, the nursing staff, the maxillofacial prosthetist, the psychiatrist, the speech therapist, the social worker, and any strong supportive members of the patient's own family.

The curative team Patients with oral cancer are referred to hospital from many sources. The general dental or medical practitioner and the ear, nose and throat and oral surgery outpatient departments in hospitals are usually the first places at which a patient with a lesion in the mouth will seek advice. When a biopsy has confirmed the diagnosis the patient with oral cancer should be seen at a joint meeting of the major group for advice and treatment planning. The surgeon will state the advantages and disadvantages of a surgical approach, the radiotherapist will discuss the technical possibilities of radiotherapy, the medical oncologist will state the way that antimitotic drugs might be of help, and the pathologist will discuiss the

histological character and likely behaviour of the tumour. A combination of approaches should be considered and a definitive treatment plan agreed by the team. After treatment the patient's progress should then be reviewed at joint meetings of the major team from time to time. There are of course many difficulties and problems when arranging for a clinical team of this sort. The difficulties start when one tries to decide which individuals will be members of the team and what qualifications, training, and experience they should possess. THE SURGEON

For various reasons (educational systems, availability of appropriate training programmes, hospital philosophy, and individual attitudes) many surgical specialties have been dealing with the treatment of patients with oral cancer. Until recently otorhinolaryngologists had the first and major responsibility in this respect. The development of otomicrosurgery and microlaryngeal surgery has diverted the interest of a number of contemporary ENT surgeons away from head and neck oncology. The same diversion has been seen among plastic surgeons with the development and spread of aesthetic and cosmetic surgery. Today their role lies largely in areas of functional reconstruction following ablation of the tumour. A new specialist, the head and neck surgeon, has been introduced lately and has received considerable publicity, mainly in the United States and Canada. The head and neck surgeon has been gaining the prior responsibility for the treatment of maxillofacial tumours in those countries. In Europe the development of maxillofacial surgeons from the medically qualified dentists of the post-war era gave the dental profession access to this field. Recently the Dental Liaison Committee of the countries of the European Economic Community with its new directives, which have now been signed by all member countries, has given the responsibility for dealing with all diseases of the mouth and adjacent structures to the dental profession. Whoever the designated surgeon is, adequate training and surgical ability in the specialised field of maxillofacial oncology are more important than his title. THE RADIOTHERAPIST

THE PATHOLOGIST

There is clearly a strong association between the histological grade of a malignant tumour of the head and neck and its subsequent behaviour, particularly within the squamouscell carcinoma group. With decreasing degree of differentiation there is an increased likelihood of regional lymph-node involvement at presentation, a reduced time interval between primary treatment and the recurrence of the tumour, and a reduced 5-year survival rate (8). It is quite clear that no treatment should be started on a patient suffering from oral cancer before the tumour's histological behaviour has been evaluated by the pathologist and discussed by the team. The oral pathologist has been assuming an increasingly important role during the past few years, particularly in stimulating the early clinical detection of oral cancer by the practising dentist (9).

Treatment planning All who are concerned with the care of patients suffering from oral cancer are well aware of the low cure rates. Oral cancer rarely kills by extension below the clavicles (io). Patients die because of our failure to control the local disease and its spread to adjacent lymphatics (8,1 i). In recent years the survival rate for the surgical treatment of head and neck cancer has assumed a plateau (3). With a better understanding of tumour biology and the patterns of spread most surgeons have realised that their results frequently depend upon biological behaviour rather than the technical refinements of surgery. Surgery and radiotherapy can be integrated in many ways to the advantage of the patient in terms of reduction in morbidity and possibly improved survival rates. Planned curative radical irradiation to the primary lesion and neck, if involved, can be given,
