Background: Gougerot-Sj\xf6gren syndrome is an autoimmune disorder with two remarkable symptoms such as dry eyes and dry mouth. Objective: To study the symptoms of dry mouth of Gougerot-Sj\xf6gren syndrome after rheumatoid arthritis; To evaluate clinical and subclinical manifestations of dry mouth. Subjects and method: A prospective, descriptive, cross-sectional study included 160 patients with rheumatoid arthritis, who treated at Department of Rheumatology of Bach Mai hospital, from 1998 to 2003. The patients were divided into 2 groups: 60 patients with Gougerot-Sj\xf6gren syndrome and 100 patients without Gougerot-Sj\xf6gren syndrome. Results: The average age of patients with Gougerot-Sj\xf6gren syndrome was 54.55 \xb1 10.91 years. The mean time of having dry mouth was 8.65 \xb1 8.39 months. Clinical manifestations of dry mouth were sensation of dry mouth (90%), lost of saliva (80%), drink a lot of water while eating (58.3%), enlargement of parotid glands (15%). Degrees of dry mouth were mild and moderate (36.7%), severe (53.3%). 93.3% of patients decreased total salivary flow.82% of patients had 3 and 4 anatomopathologic stages according to Chilsom classification. Conclusion: Incidence of symptoms of dry mouth was higher significantly in the rheumatoid arthritis patients with Gougerot-Sj\xf6gren syndrome than those without Gougerot-Sj\xf6gren syndrome.

OBJECTIVE: To study our experiences on deep lobe tumor parotidectomy with preservation of the superficial lobe of the parotid gland. METHOD: Eleven cases of benign tumor in the deep lobe of the parotid gland were analyzed restrospectively. Tumour recurrence, Frey's syndrome, paralysis of facial nerve, salivary fistula, dry mouth and feeling around the auricular lobule were evaluated. RESULT: Numbness around the auricular lobule appeared in 2 cases and salivary fistula appeared in 1 case, transient facial paralysis in 1 case. There were no patients appeared Frey's syndrome, dry mouth, permanent facial paralysis and recurrence in the 1-3 years followed up time. CONCLUSION Deep lobe tumor parotidectomy with preservation of the superficial lobe improves the cosmetics and the feeling around the auricular lobule, reduces the incidence rate of Frey's syndrome, facial paralysis and dry mouth.

The saliva secreted from submandibular gland (SMG) accounts for 60%-65%. It plays an important role in maintaining the human function of swallow, digestion, testing, speech, protection of oral mucosa, and prevention from dental carries. The SMG is frequently resected during the treatment for various kinds of oral and maxillofacial diseases, resulting in xerostomia and decreased quality of life. During the past 15 years, Research Center of Salivary Gland Diseases in Peking University School and Hospital of Stomatology conducted a series of studies on new techniques for preservation of SMG and achieved remarkable results. The clinicopathologic and imaging characteristics of IgG4-related sialadenitis (IgG4-RS) were clarified based on systematic studies. The results of studies on the pathogenesis of IgG4-RS showed that unbalance of inflammatory factors mediated the abnormality of secretion of SMG. IL-4 participates in occurring and development of glandular fibrosis of SMG. Regulation of tumor necrosis factor α (TNF-α) and cleaning of senescent cells might be taken as the targets for treatment of IgG4-RS. The combination of glucocorticoid and steroid-sparing agents showed effective results for treating IgG4-RS, clinical remission was achieved in all the patients, serum IgG4 levels decreased, and salivary gland secretion significantly increased. Sialoendoscopy-assisted sialolithectomy was applied in the treatment of about 1 000 cases with submandibular hilar calculi with a success rate of more than 90%. Transfer of SMG was used for prevention from radiation-induced xerostomia in the patients with head and neck carcinoma. SMG was transferred to the submental region before radiotherapy and was kept away from the ra-diation field. The results of prospective clinical controlled study showed this technique could effectively preserve the function of SMG and prevent from xerostomia. Based on the micro-anatomical study on the blood vessels and ducts of SMG, partial sialoadenectomy was applied for treatment of benign tumors in the SMG. A clinical controlled study confirmed its safety for control of the tumors and its advantage of preservation of SMG function. The studies on the involvement of SMG in oral squamous cell carcinoma (OSCC) provided the anatomical and histopathological basis for preservation of SMG during neck dissection for early cases with OSCC. A innovated surgical modality "four preservations including SMG" was used during the neck dissection for the early cases with OSCC. A prospective randomized clinical controlled study confirmed its safety, feasibility, effectiveness for control of the carcinoma, and advantages of preservation of SMG function.

OBJECTIVE: To investigate the clinical value that surgical treatment with comprehensive treatment in treating early stage nasopharyngeal carcinoma. METHOD: Based on the case selection criteria, patients with early nasopharyngeal carcinoma were divided into surgery group and the conventional group according to patients' wishes. Surgery group were treated with surgery plus Radiochemotherapy as a comprehensive treatment while conventional group were treated with Radiochemotherapy. Outcome indices: (1) 5-year survival rate and 5-year disease-free survival rate; (2) Radiation dose to the nasopharynx; (3) Incidence of xerostomia. RESULT: (1) The overall 5-year follow-up rate was 97.12%; 1 patient was lost to follow-up in surgical group, the 5-year follow-up rate was 96.77%; 2 patients were lost in conventional Group with 5-year rate of 97.26%. (2) The 5-year survival rate of 104 patients was 83.65% (87/104). (3) The 5-year survival rate and 5-year tumor-free survival rate were 96.77% (30/31) and 93.55% (29/31) in surgical group, 78.08% (57/73) and 73.97% (54/73) in conventional group. There were significant differences between the two groups (P < 0.05). (4) The radiation dose to the nasopharynx in surgery group and conventional group were (63.90 +/- 5.56) Gy and (71.48 +/- 4.18)Gy, respectively; the dose in surgical group was significantly less than the conventional group, there were statistical significance between the two groups. (5) The incidence of xerostomia was significantly less in surgical group (22.58%) than conventional group (65.75%), the difference was statistically significant. CONCLUSION The surgery combined with concurrent chemoradiotherapy is a effective comprehensive therapeutic interchange program for early stage nasopharyngeal carcinoma. These program can increase the long-term survival rate, but also reduce the radiation dose to the nasopharynx and the occurrence of radiation complications. A further aspect is worth consideration.

The management of cervical lymph node metastases of squamous cell carcinoma from an unknown primary site is still a therapeutic challenge. We report here our experience in treating these patients with chemoradiotherapy as a curative approach. Data from 40 patients were reviewed. In total, 20 (50%) patients underwent excisional biopsy. All patients underwent radiotherapy, which was delivered to both sides of the neck and pharyngeal mucosa (extensive field), and concurrent chemotherapy consisting of weekly cisplatin at a dose of 40 mg/m(2). The clinical stage of the cervical nodes at presentation was N1 in 25%, N2 in 60%, and N3 in 15%. Most patients (75%) developed at least grade 3 mucositis. Eight patients (20%) had grade 3 xerostomia and 18 patients (45%) required esophageal dilation for stricture. The 5-year overall survival(OS) rate of all patients was 67.5%. The 5-year OS rates of patients with N1, N2, and N3 lesions were 100%, 67%, and 41%, respectively (P = 0.046). The 5-year progression-free survival rate was 62.5%. In multivariate analysis, only N stage significantly affected OS(P = 0.022). Emergence of the occult primary was very limited (1 patient only). Our results suggest that extensive irradiation of both sides of the neck and pharyngeal mucosa with concurrent chemotherapy results in a lower emergence of primary tumor. Because the survival of patients with unknown primary is comparable to that of patients with known primary, an attempt at cure should always be made.

The application of simultaneous integrated boost-intensity modulated radiotherapy (SIB-IMRT) in pediatric and adolescent nasopharyngeal carcinoma (NPC) is underevaluated. This study aimed to evaluate long-term outcome and late toxicities in pediatric and adolescent NPC after SIB-IMRT combined with chemotherapy. Thirty-four patients (aged 8-20 years) with histologically proven, non-disseminated NPC treated with SIB-IMRT were enrolled in this retrospective study. The disease stage distribution was as follows: stage I, 1 (2.9%); stage III, 14 (41.2%); and stage IV, 19 (55.9%). All patients underwent SIB-IMRT and 30 patients also underwent cisplatin-based chemotherapy. The prescribed dose of IMRT was 64-68 Gy in 29-31 fractions to the nasopharyngeal gross target volume. Within the median follow-up of 52 months (range, 9-111 months), 1 patient (2.9%) experienced local recurrence and 4 (11.8%) developed distant metastasis (to the lung in 3 cases and to multiple organs in 1 case). Four patients (11.8%) died due to recurrence or metastasis. The 5-year locoregional relapse-free survival, distant metastasis-free survival, disease-free survival, and overall survival rates were 97.1%, 88.2%, 85.3%, and 88.2%, respectively. The most common acute toxicities were grades 3-4 hematologic toxicities and stomatitis. Of the 24 patients who survived for more than 2 years, 16 (66.7%) and 15 (62.5%) developed grades 1-2 xerostomia and ototoxicity, respectively. Two patients (8.3%) developed grade 3 ototoxicity; no grade 4 toxicities were observed. SIB-IMRT combined with chemotherapy achieves excellent long-term locoregional control in pediatric and adolescent NPC, with mild incidence of late toxicities. Distant metastasis is the predominant mode of failure.

BACKGROUND AND OBJECTIVERadiotherapy is effective in treating nasopharyngeal carcinoma (NPC). This study evaluated the treatment efficacy, toxicity, and prognostic factors of intensity-modulated radiotherapy (IMRT) in the treatment NPC.

METHODSBetween September 2003 and September 2006, 305 patients with NPC were treated with IMRT in Fujian Provincial Cancer Hospital. IMRT was delivered as follows: gross tumor volume (GTV) received 66.0-69.8 Gy in 30-33 fractions, high-risk clinical target volume (CTV-1) received 60.0-66.65 Gy, low-risk clinical target volume (CTV-2) and clinical target volume of cervical lymph node regions (CTV-N) received 54.0-55.8 Gy. Patients with stages III or IV disease also received cisplatin-based chemotherapy. All patients were assessed for local-regional control, survival, and toxicity.

RESULTSWith a median follow-up of 35 months (range, 5-61 months), there were 16, 8, and 39 patients who had developed local, regional, and distant recurrence, respectively. The 3-year rates of local control, regional control, metastasis-free survival, disease-free survival, and overall survival were 94.3%, 97.7%, 86.1%, 80.3%, and 89.1%, respectively. Multivariate analyses revealed that T-classification had no predictive value for local control and survival, whereas N-classification was a significant prognostic factor for overall survival (P < 0.001), metastasis-free survival (P < 0.001), and disease-free survival (P = 0.003). For stages III-IV disease, concurrent and adjuvant chemotherapy did not influence prognosis. The most severe acute toxicities included Grade III mucositis in 14 patients (4.6%), Grade III skin desquamation in 90 (29.5%), and Grades III-IV leucocytopenia in 20 (6.5%). There were 7% patients with Grade II xerostomia after 2 years of IMRT, no Grades 3 or 4 xerostomia was detected.

CONCLUSIONSIMRT provided favorable locoregional control and survival rates for patients with NPC, even in those with locally advanced disease. The acute and late toxicities were acceptable. N-classification was the main factor of prognosis. Further study is needed on chemotherapy for patients with NPC.
