Studying the dynamy of immunobiological parameters after radiotherapy and estimating its prognostic values on 77 NPC patients with T1-3No-3Mo (UICC 1979) at Hanoi K hospital from 11/1994 to 12/1998. We have some results: The prognostic values have been found significantly in the quantity of leukocytes, the level of serum IgA/VCA, IgG/EBNA before radiotherapy, the frequency of HLA antigens A11, A2, B17 and the desequilibre linkage A11-B17, A2-B17. Especially, the increase of serum IgA/VCA after radiotherapy has significantly predicted recurrence of studied NPC patients

By the technique of indirect immunofluoresceine using 18 diverse markers, in the hospital K- Ha Noi, study was performed to determine the capacity of foreign antigene expression of tumor cells in the cell surface making them identified by immunology system through HLA system on NPC < 75 years old age patients. This system played an essential role in the regulation and realization of immune response.

In order to investigate the changes of some cytokines in NPC patients, we have made an measure of IL-2 and IL-10 in cell culture supernatants on 22 NPC patients, at II, III, IVa, IVb stage, positive anapathological test, compare with 12 healthy age-matched controls. The obtained results showed that: IL-2 production was significantly depressed in cell culture supernatants of NPC patients compare with control group. The production of IL-10 was increased in cell culture supernatants of NPC patients at late stages. It suggested that, IL-10 may be an prognostic factor in severe NPC patients and may prove valuable in selecting with NPC who are candidates for aggressive therapy

Low grade nasopharyngeal papillary adenocarcinoma (LGNPPA) is an extremely rare variant of nasopharyngeal cancer, which exhibits distinct clinicopathological characteristics. Surgical resection has been regarded as the principal treatment. For this, transpalatal or transfacial approach has been classically used for exposure of the field. Up for now, there has been no report on applying endoscopic approach for this disease, which could be an effective alternative to minimize possible morbidities of palatotomy or maxillotomy. Endoscopic approach can be justified considering narrow extent and indolent behavior of LGNPPA. We report a patient with LGNPPA, which was successfully resected exclusively by endoscopic visualization. Our case exhibited narrow-based exophytic features with compatible immunopathologic profiles of LGNPPA. Exclusive endoscopic resection can be effective and less-morbid modality for this rare disease as in this case.

OBJECTIVE: To study the clinical features, diagnosis and treatments of primary nasopharyngeal tuberculosis. METHOD: A case report was presented, and meanwhile etiopathogenesis and differential diagnosis were also reviewed. RESULT: A biopsy was taken and the histopathological examination showed tuberculosis granuloma with caseous necrosis. After anti-tuberculosis therapy, the symptoms disappeared. CONCLUSION Not only otologic disorders but also nasopharyngeal diseases need to be considered when aural fullness exists. More importantly, primary nasopharyngeal tuberculosis should be taken as one of the differential diagnosis.

OBJECTIVETo evaluate the value of narrow band imaging (NBI) endoscopy in the diagnosis of nasopharyngeal lesions.

METHODSBetween December 2009 and April 2010, a total of 124 patients with nasopharyngeal lesions were examined with electronic nasopharyngolaryngoscope equipped with the white light mode and NBI mode. The biopsies of nasopharyngeal lesions were done in all patients. The characteristics of morphologies of mucosa and mucosal superficial vessels of each lesion under NBI mode were evaluated.

RESULTSOf all cases, there were 1 of papilloma, 87 of lymphoid follicular hyperplasia and chronic inflammation, 11 of nasopharyngeal cysts, and 25 of nasopharyngeal carcinoma. According to the pathological results, the morphologies of nasopharyngeal lesions under NBI mode were quite different. The color depth of the mucosa could be divided into four types: light red (+), dark red (++), prunosus (+++), and blue or blue black (++++). Under NBI, the color depths were (+) in papilloma, (++) in nasopharyngeal cysts, and (+++) in lymphoid follicular hyperplasia and chronic inflammation, without abnormal vessels. The color depths were (+++)-(++++) in nasopharyngeal cancer, with abnormal vessels.

CONCLUSIONNBI has a potential ability to predict pathological results of nasopharyngeal lesions.

Objective:To compare the clinical effects and complications of surgery + chemotherapy and radiotherapy + chemotherapy in patients with nasopharyngeal carcinoma recurrence, so as to compare the safety and efficacy of two different therapeutic methods. Methods:A retrospective analysis was performed on 40 patients with recurrent nasopharyngeal carcinoma after radiotherapy and chemotherapy admitted to our hospital from January 2016 to June 2020. Among them, 26 patients were treated with surgery. The recurrent tumor was removed under nasal endoscope, and the frozen resection margin was negative during the operation. Chemotherapy was continued for stage Ⅲ and Ⅳ patients from 3 to 5 weeks after surgery. Fourteen patients received secondary radiotherapy and chemotherapy. Postoperative complications and survival rate were observed. Results:There were 14 patients in the secondary chemoradiotherapy group（control group） and 26 patients in the nasal endoscopic surgery group（observation group）. Among the 26 patients, 19 patients underwent nasal septal mucosal repair, 5 patients underwent temporal muscle flap repair, 2 patients underwent submental flap repair, 2 patients had nasal septal mucosal flap necrosis and cerebrospinal fluid leakage, and the temporal muscle flap was used for secondary repair in the second stage operation, and 8 patients needed cervical lymph node dissection. The patients recovered well after surgery, and the patients in stage Ⅲ and Ⅳ were treated with chemotherapy after 3 weeks to 5 weeks according to the patient's wound condition. There were significant differences in the incidence of complications and 1-, 2-, and 3-year survival rates between the two groups（P<0.05）. Conclusion:Patients with recurrent nasopharyngeal carcinoma can be treated by nasal endoscopic surgery to remove the tumor, and the use of pedicled nasal septal mucosal flap or temporal muscle flap for skull base reconstruction, The operation can effectively prevent major complications such as internal carotid artery rupture and hemorrhage, and improve the survival rate and quality of life of patients. It provides a safe and effective treatment for patients with recurrent nasopharyngeal carcinoma.
