Study in 195 oropharyngeal carcinoma patients, results showed that this cancer mainly occurred in the group of 40-70 years old (70%), male was more often than female (2.8 times), duration of onset: <3 months: 40%, 3-6 months: 30.2%, 6-12 months: 18.4%, >12 months: 10.7%. Symptoms are: sore throat 59.7%, dysphagia 73.3%, changes of voice 43%, bleeding phlegm 15.8%, difficult swallow 7.8%, and lock-jaw 20.7%. Primary tumors on the right/left were 49.7% and 50.3%. 87.6% of lymph nodes were on the same side of tumors, 12.3% on the opposite side. Most patients have been diagnosed in late stages. 74.8% tumors were squamous cell carcinoma, 25.2% were undifferentiated carcinoma.

The retrospective study was carried out on 142 nasopharyngeal carcinoma patients between 20 and 45 years old. Results prognosis of early stage was better. Middle-aged patients have better. It’s necessary to propagandize early clinical symptoms of disease so more patients received early treatment. The later stages the worse prognosis because there is high risk of metastasis and recurrence. Radio-chemotherapy will help to prevent metastasis and recurrence.

195 patients with tonsil carcinoma were treated by simple external radiation at K Hospital from January 1990 to January 2001. Results showed: the rate of response to simple external radiation in all episode was 58.9%, partial response 41.1%, no unresponsive case or progresive case. The rate of responsive effect of external radiation on tumor was T1, T2 - 100%, T3 - 47%, T4 - 0%, N1 - 100%; N2 - 82.4%; N3 - 20.4%. The responsive rate of external radiation on tumor and adenomas was depended mainly on the sign, the invasion of the tumor and the adenome, but no relation with histopathological type.

A study on 21 patients with ages of 5-70 and cerebral stellate cellular tumor has found that the poor prognosis was increased with age, nervous lesion and size of tumor. The tumor in brain had prognosis poorer than this in cerebellum. The treatment involved the operation combining with radiation.

The study aimed to establish the treatment strategy for some common tumors of the central nervous system. 43 patients with brain tumors and a patient with myeloma who admitted since 1995 were investigated retrospectively. It was found that invasive astroma and glioblastoma multiforme was commonest. There was not significant relationship between clinical features of brain tumor and type of cytology. Aggressiveness mainly related to the region and the volume of tumor. Located clinical signs tend to promote the patient seeking health care. Definitive diagnosis is based on histopathological findings with surgery or needle biopsy. Surgery is main option for treatment. Post operative radiotherapy was indicated for most of patients.

Among 156 patients with ages of 15-80, suffering the major salivary cancer in which parotid salivary cancer (73.5%), mandibullar salivary (26.5%), 15% of patients had symptoms of paralysis of peripheral facial nerve. 9.6% of patients had persistent pain. The patients received an operation for selective ganglion curettage. If the ganglion was positive, postoperative radiation indicated for both tumor and ganglion at dose of 70 Gy. If the ganglion was negative, the postoperative radiation indicated for primary tumor at dose of 70 Gy. Results: the total survival rate after 3 years and 5 years of the treatment was 74.1 and 60.6%, respectively. The local relapse rate after the single operation, radiation at dose of 50 Gy and dose of 70 Gy was 48.1%, 71.4% and 3% respectively

The study involved 51 patients with primary brain tumors and 8 patients with brain metastasis from acute leukemia. Age of patients ranged from 5 to 70 years. Drugs for anti-cerebral edema were administered 48 - 72 hours before radiotherapy. For patients with high-volume primary brain tumors, synacthen 1 mL x1 ampoule daily was used and dexamethasone 16-20 mg daily was administered during radiotherapy. For patients with acute leukemia, dexamethasone 8 - 16 mg was used daily. Results: It is possible to prevent from acute cerebral complications if the conventional dose division of radiotherapy is performed appropriately with use of anti-cerebral edema drugs around radiotherapy. The closed monitoring must be given for cases in which chemotherapy, especially methotrexate, was used with radiotherapy

15 patients (2 women and 13 men) with astroma treated at K Hospital since 1996 were studied retrospectively. Age of patients ranged from 9 to 54 years. Site of tumors included cerebellum (2 cases), temporal lobe (6 cases), parietal lobe (6 cases) and frontal lobe (1 case). Histopathological findings showed that 4/15 astromas were at grade 1; 5/15 were at grade 2; 1/15 were at grade 3 and 1/15 was at grade 4 of malignance scale; 2/15 astromas were not scaled. 12/15 patients were removed their tumors by operation, in which 3 patients had topical recurrence of tumor were re-operated. 3 patients were operated to remove tumors partially. 15/15 patients received radiotherapy. 14/15 patients had lived over 3 months, 12/15 patients over 6 months, 9/12 patients over 1 years and 5/7 patients over 3 years after operation and radiotherapy. 2 patients had complication (severe headache). Anti-cerebral edema medications were needed

142 cases of nasopharyme cancer were treated by radiotherapy using the method of sample external radotherapy and method of external radio therapy and method of external radio therapy in combining with the source of radium applied in situ supported by a foam rubber hoder. Results showed that by combining method reduced the risk of recurrence occurred later and in a location other than the primary cancer. The technique was carried with low cost and easy looking for materials.

For detecting mouth cavity cancers, it must pay attention on the high risk factors group (above 45 years old, alcoholism, smoking and betel using); Abnormal feeling in the mouth (bleeding of tooth root, or red, white piece appeared, persistently exist in mouth). When the obove mentioned signs exist more than two weeks after infecting antibiotics and using antiflammatory medicines. To affirm the diagnosis, biopsy must be made in suspected case; Toludine blue dying must be made to detect early the abnormalties.
