  • Due to the low incidence and histologic diversity of salivary gland cancer, analyzing the incidence of salivary gland cancer is necessary to understand the macroscopic aspects. We intend to investigate the international trend of the reported incidence rate of salivary gland cancer. Using the Korea Central Cancer Registry data, the domestic change in the incidence rate was examined. As a result, a significant increasing trend was confirmed, consistent with the United States and Japan trends. The etiology of the change is unclear, and various factors that may influence the direction are reported. Additional research is needed to understand the pathophysiology of salivary gland cancer, and further efforts are required to understand salivary gland cancer.

  • Salivary gland tumors are relatively rare, constituting 3% of all head and neck neoplasms. In patients with salivary gland malignancies, $^{18}F-FDG$ PET is clinically useful in initial staging, histologic grading, and monitoring after treatment. According to clinical research data hitherto, $^{18}F-FDG$ PET is expected to be an effective diagnostic tool in the management of salivary gland tumors.

  • The pain, swelling of salivary glands and dry mouth are not infrequent complication of the high dose radioiodine treatment in the patients with differentiated thyroid cancer. The purpose of this study was, by the dynamic salivary scintigraphy, to observe the change of the salivary function after the high dose $(150\sim200mci)$ radioiodine treatment. From May 1987 to April 1988, the dynamic salivary scintigraphy with 5mci of $^{99m}Tc-pertechnetate$ and gamma camera was performed before and 7 days after the radiolodine treatment in 7 patients with differentiated thyroid cancer. Just after the dynamic scintigraphy, the stimulation test with vitamin C solution of pH3.0 and poststirnulation scintigraphy were done, and the radioactivity uptake index, excretion fraction and salivary clearance after the stimulation were calculated for each gland. There was positive correlation between the radioactivity uptake index and excretion fraction after the stimulation. The salivary clearance after the stimulation was $18.96{\pm}8.95ml/min$ in the pretreatment state, and $14.37{\pm}7.7ml/min$ after the radioioine treatment. After the radioiodine treatment, the radioactivity uptake index, excretion fraction and salivary clearance after the stimulation were significantly reduced in the parotid glands, but only the excretion fraction was reduced in the submandibular glands. The more the pretreatment salivary clearance after the stimulation was, the % change after the treatment was smaller. Further studies on the relation between the radiation dose in the salivary glands and the change of their function, and the long-term observation for the recovery of function are expected.

  • The purpose of this study is to evaluate salivary flow rate, salivary pH, and cariogenic activity using unstimulated saliva of the head and neck cancer patients. Twenty three cancer patients (19 males, 4 females) who had undergone chemotherapy and radiation therapy and twenty four healthy volunteers (14 males, 10 females) as a control were included. Salivary flow rate, salivary pH, and cariogenic activity using unstimulated saliva were examined. Compared to saliva of the control group, salivary flow rate (p<0.001) and salivary pH (p<0.001) were significantly lower in head and neck cancer patients. The colony counts of Lactobacilli was higher in head and neck cancer patients (p<0.05) than in control group. These salivary factors and cariogenic activity can increase the prevalence of dental caries in head and neck cancer patients.

  • The result of neutron therapy on head and neck cancer using KCCH -Cyclotron neutron which had been using from October 1986 to September 1989 in the Korea Cancer Center Hospital. Among the total of 27 patients the cases of malignant salivary gland tumor were 14 and the cases of advanced head and neck cancer of AJCC stage IV were 13. The local control rate was 80% in malignant salivary gland tumor and 46.2% in advanced head and neck cancer. The 2 year survival rate was 60% in malignant salivary gland tumor and 38.5% in advanced head and neck cancer. Although there was no significant difference in prognosis according to the pathologic types, squamous cell carcinoma revealed a pattern of poor prognosis. The major complication from the neutron therapy had developed 7.1% in malignant salivary gland tumor and 23.1% in advanced head and neck cancer. In conclusion, neutron therapy is superior in the treatment of malignant salivary gland tumor and also effective in the treatment of advanced head and neck cancer when it can avoid to treat some site of low tolerance.

  • Objectives: Major salivary gland tumor mainly develops in the parotid gland and pleomorphic adenoma is a large percentage. The aim of this study is to get clinicopathologic characteristics of overall major salivary gland tumors and suggestions regarding surgical management through collective review of 315 cases. Materials and Methods: This is a clinicopathologic review of 315 cases of major salivary gland tumor who were treated surgically at Department of Surgery, Head and Neck Clinic, Pusan Paik Hospital, Inje University during the period of 18 years from 1980 to 1997. Analysis was performed regarding the incidence, classification, surgery and its complications, and survival rate of salivary gland cancer. Results : 1) Parotid gland was the most prevalent site of salivary gland tumor(78%) and submandibular gland(21%) was next in order. Benign tumors were 257cases(81%) and malignant tumors were 58 cases(19%). 2) Male to female sex ratio was 1:1.2, the most prevalent age group was 3rd decade and the second group was 4th decade. 3) Histopathologically, the most common benign salivary gland tumor was pleomorphic adenoma. Warthin's tumor was next common. Among the malignant tumors, mucoepidermoid carcinoma was most common, and the next were adenoid cystic carcinoma and acinic cell carcinoma. 4) In pleomorphic adenoma, superficial parotidectomy was performed in 129 cases, and extracapsular tumorectomy was performed in 3 cases. In non-pleomorphic benign tumor, tumorectomy was performed in 21 cases. In 40 cases of deep lobe tumor, total parotidectomy was performed in only 2 cases and deep parotidectomy was performed in 38 cases. 5) Surgical complications were facial nerve injury 19 cases, Frey syndrome 13 cases, and salivary fistula 3 cases. 6) Overall 5-year survival rate of salivary gland cancer was 63%. Conclusion: Postoperative recurrence rate is low in benign tumor, but high in cancer of salivary gland tumor. Surgical procedure should not be aggressive in benign tumor, especially in parotid tumor, but should be aggressive in malignant salivary gland tumors.

  • Background: The aim of this work was to investigate if serum and salivary auto-antibodies, isotypes IgG and IgM, against HER2 and MUC1 tandem repeat fragments could play a role in breast cancer screening. Materials and Methods: Our case-control study was conducted in breast cancer patients, in early stages (n=29), at the gynecology service, Maternity Souissi Hospital, Rabat, Morocco and healthy woman (n=31). Salivary and serum auto-antibodies against HER2 and MUC1 (tandem repeat) were assessed by enzyme-linked immunosorbent assay (ELISA) and compared between patients and healthy women using the Mann-Whitney U test. A P-value <0.05 was considered to be statistically significant. Results: Our data showed higher expression of all serum and salivary autoantibodies in patients as compared to healthy women p<0.05. However, serum IgM anti-MUC1 expression did not show a significant difference between cases and controls (p=0.79). Similarly, salivary IgG anti-HER2 expression did not differ (p=0.15). The correlation between the different isotypes of antibodies revealed that the highest correlation was between salivary IgG anti-HER2 and salivary IgG anti-MUC1(r=0.65). In fact, we have found in saliva the correlation between autoantibodies anti-MUC1 and anti-HER2 more important than in serum (r=0.59 and r=0. 55). However, the correlation between serum and saliva values for all antibodies was weak. Conclusions: Autoantibodies against HER2 and MUC1 may provide a useful approach in breast cancer screening when using both serum and saliva values.

  • Background: Despite being rare in incidence, malignant tumors of major salivary glands show diverse histological variation. There are limited data on major salivary gland tumor management and outcome from Pakistan. The objective of this study was to share our experience with management of malignant tumors of major salivary glands. Materials and Methods: Patients who received treatment at Shaukat Khanum Cancer Hospital and Research Center from July 2002 to June 2011 with an underlying diagnosis of a major salivary gland malignancy were included. Patient characteristics and treatment modalities were assessed. Local, regional and distant failures were determined. Disease free survival (DFS) and overall survival (OS) were calculated using Kaplan Meier curves and the Log rank test was used to determine statistical significance. Univariate and multivariate analyses were performed using Cox proportional hazard regression. Results: The parotid gland was the primary site of origin in 104 (80%) patients. Mucoepidermoid carcinoma (43%) and adenoid cystic carcinoma (24%) were the most common histological types. Surgery followed by adjuvant radiation remained the mainstay treatment modality with 81 (62%) patients. Nineteen (15%) patients were treated with surgery alone and 30 (23%) patients with locally advanced surgically inoperable tumors received radiation only. Forty one (32%) patients failed the treatment (local 12, regional 11, locoregional 5, distant 13). The expected 5 year DFS and OS were 65% and 74% respectively. On multivariate analysis, grade was the only independent predictor of DFS and nodal involvement was the only independent predictor of overall survival. Conclusions: Employing existing standards of treatment, comparable survival can be achieved in Pakistani population with major salivary gland malignancies as elsehwere in the world.

  • The authors reviewed 114 cases of malignant major and minor salivary gland tumors at Presbyterian Medical Center seen from February, 1963 to December, 1983. The results were obtained as follows; 1) Overall male and female sex ratio was 2:1. The peak age of patients with major and minor salivary gland tumor were both 5 th decade. 2) The ratio of benign and malignant tumor was 83:114. The incidence of malignancy in each group was 52% in parotid (50 patients), 75% in minor salivary gland (45 patients), 49% in submaxillary gland(18 patients) and 25% in sublingual gland (1 patient). 3) The incidence according to the anatomic primary site for minor salivary cancers was 10 cases in the nasal cavity, each 8 in the palate and the maxillary antrum, 7 in the tongue, 5 in the gum, 3 in the larynx and 2 in the buccal mucosa. 4) Adenoid cystic carcinoma was the most common cancer of minor salivary gland and malignant mixed tumor was the most common in major salivary glands, each comprising 34 cases (76%) of minor and 19 cases (28%) of major salivary gland tumors. 5) The incidence of cervical lymph node metastasis was 50% in the submaxillary gland cancers, 44% in the parotid gland cancers and 21% in malignant tumors of minor salivary glands. The highest incidence of lymph node metastasis according to histopathological classification was formed in high grade of mucoepidermoid (67%). 6) Nerve invasion was common in mucoepidermoid carcinoma. According to anatomic site, nerve invasion occurred most often in adenoid cystic carcinoma of the submaxillary gland (44%). 7) The lung was the commonest site for distant metastasis comprising 12 cases among 26 cases in which distant spread occurred. 8) The recurrence rate was 50% for major salivary gland cancer and 52% in cancer of the minor salivary gland. In accordance with pathological classification, adenocarcinoma most frequently recurred after excision. This being seen in 88% of patients undergoing definitive therapy. 9) The determinate 5 year survival rate was 78% in major salivary gland tumors, but 69% in minor salivary gland tumors.

  • Background and Objectives: Nodal metastasis is one of the prognostic factors in salivary gland cancer. The purpose of this study is to identify risk factors of nodal metastasis considered as a predictor of poor prognosis in patients with salivary gland cancer. Material and Methods: The authors retrospectively studied 82 patients with salivary gland cancer who underwent surgery from 1992 to 2002. We analyzed age, sex, tumor size, histologic type and 5-year survival rate to compare patients with and without nodal metastasis. Results: Mean age was 55.4 years, with a male-female ratio of 1 : 1.28. The overall 5-year survival rate was 85.5%. Among the 82 patients, 14 patients had nodal metastasis. There was no nodal metastasis in low grade malignancy. In patients without nodal metastasis, mean age was 52.5 years and the overall 5-year survival rate was 94.2%. In patients with nodal metastasis, mean age was 69.4 years and the overall 5-year survival rate was 42.9%. In patients with less advanced cancer (T1-T2 stage), the nodal metastasis was 7.5% and with advanced cancer (T3-T4 stage), 33.3%. Conclusion: Nodal metastasis significantly decreases survival in patients with salivary gland malignancy. High grade malignancy, large tumor size and old age are important risk factors of nodal metastasis. Nodal metastasis is more common in submandibular gland cancer compared with parotid gland cancer.
