OBJECTIVE:
To investigate the clinical application and efficacy of 125Ⅰ radioactive seeds implantation in the treatment of recurrent salivary gland carcinoma after external radiotherapy.
METHODS:
From July 2004 to July 2016, 43 cases of recurrent salivary gland carcinoma of the neck after external radiotherapy or surgery combined with external radiotherapy were treated. According to the conventional segmentation radiotherapy for head and neck cancer (once a day, 1.8-2.0 Gy each time, 5 days per week), the cumulative radiation dose of the patients in this group was calculated. In the study, 26 patients received 50-60 Gy, 7 patients received less than 50 Gy, 4 patients received 60-70 Gy, and 6 patients received more than 80 Gy (range: 80-120 Gy). The interval between the last external irradiation and local recurrence was 4-204 months, and the median interval was 48 months. Among them, 25 cases were treated with 125Ⅰ radioactive seeds implantation only and 18 cases were treated with 125Ⅰ radioactive seeds implantation after operation. The prescription dose was 100-140 Gy. The control rate, survival rate and disease-free survival rate were recorded to evaluate the side effects.
RESULTS:
The median follow-up time was 27 months (ranging from 2.5 to 149.0 months). Among them, the median follow-up time of adenoid cystic carcinoma patients was 31 months (range: 2.5-112.0 months), and the median follow-up time of mucoepidermoid carcinoma patients was 18 months (range: 5-149 months). The local control rates for 1, 3 and 5 years were 66.5%, 48.8% and 42.7%, respectively. The 1-, 3- and 5- year survival rates were 88.0%, 56.7% and 45.8%, respectively. The disease-free survival rates of 1, 3 and 5 years were 58.3%, 45.4% and 38.1%, respectively. There was no statistically significant difference in local control rate, survival rate, and disease-free survival between the radioactive seeds implantation group and the radioactive seeds implantation group after surgical resection. There were 2 cases of acute radiation reaction Ⅰ/Ⅱ and 3 cases of reaction Ⅲ or above. In the late stage of radiotherapy, there were 8 cases with Ⅰ/Ⅱ grade reaction and 3 cases with Ⅲ grade or above reaction. The incidence of radiation reactions of Grade Ⅲ and above was 7%.
CONCLUSION
125Ⅰ radioactive seeds implantation provides an alternative method for the treatment of recurrent salivary gland carcinoma after external radiotherapy. The local control rate and survival rate are improved on the premise of low incidence of side effects.

Sebaceous carcinoma of the salivary gland is an extremely unordinary malignancy occurring mainly in the parotid gland. Sebaceous carcinoma arising in the submandibular gland is exceptional and only three cases have been reported in the literature. We herein present a unique case of sebaceous carcinoma of the submandibular gland, the first to be reported in literature in South Korea. An 85-year-old man visited our hospital complaining of a progressively enlarging submandibular mass with tenderness and ipsilateral facial palsy. We performed a wide excision of the mass with superficial parotidectomy and modified neck dissection. Microscopic and immunohistochemical examinations demonstrated sebaceous carcinoma of low grade differentiation. Further adjuvant radiotherapy was rejected and the patient was followed up for five months. The optimal treatment of sebaceous carcinoma of the salivary gland is still not established due to the rarity of the disease. When more cases are reported, the clinicopathologic characteristics will be better understood.

4.Postoperative radiotherapy for mucoepidermoid carcinoma of the major salivary glands: long-term results of a single-institution experience
Radiation Oncology Journal 2018;36(4):317-324
PURPOSE: This study aimed to evaluate the long-term survival outcomes and prognostic factors that affect the clinical outcomes of patients who underwent surgery and postoperative radiotherapy for major salivary gland mucoepidermoid carcinoma (MEC). MATERIALS AND METHODS: We retrospectively reviewed the clinical data of 44 patients who underwent surgery followed by radiotherapy for primary MEC of the major salivary glands between 1991 and 2014. The median follow-up period was 9.8 years (range, 0.8 to 23.8 years). RESULTS: The overall outcomes at 5 and 10 years were 81.5% and 78.0% for overall survival (OS), 86.2% and 83.4% for disease-free survival, 90.6% and 87.6% for locoregional recurrence-free survival, and both 90.5% for distant metastasis-free survival (DMFS). Histologic grade was the only independent predictor of OS (low vs. intermediate vs. high; hazard ratio = 3.699; p = 0.041) in multivariate analysis. A poorer survival was observed among patients with high-grade tumors compared with those with non-high-grade tumors (5-year OS, 37.5% vs. 91.7%, p < 0.001; 5-year DMFS, 46.9% vs. 100%, p < 0.001). CONCLUSION: Surgery and postoperative radiotherapy resulted in excellent survival outcomes for patients with major salivary gland MEC. However, high-grade tumors contributed to poor DMFS and OS. Additional aggressive strategies for improving survival outcomes should be developed for high-grade MEC.

Acinic cell carcinoma (ACC) is an uncommon malignant tumor of the salivary glands that is difficult to diagnose. It grows slowly and shows distant metastasis rarely. We experienced a case of recurrent ACC in the parotid gland with cardiac metastasis and hypertrophic osteoarthropathy. The 29-year-old man had been suffering from severe multiple bones and joints pain for 2 months. Ten years earlier, he underwent superficial parotidectomy due to a right subauricular mass. The mass was diagnosed with ACC. After surgery, the tumor recurred twice. Then the patient was diagnosed with cardiac metastasis via positron emission tomography-computed tomography and trans-thoracic echocardiography. He also had hypertrophic osteoarthropathy with multiple bone metastasis. He was given palliative radiotherapy and conservative treatment. ACC in the parotid gland with cardiac metastasis and hypertrophic osteoarthropathy has not yet been reported in literature. From this case, it is recommended to evaluate multiple distant metastasis in the ACC of the parotid gland when joint and bone pain are present.

OBJECTIVE: To investigate the value of diffusion-weighted magnetic resonance imaging (DW-MRI) as a noninvasive tool to assess salivary gland function for follow-up of patients with radiation-induced xerostomia. MATERIALS AND METHODS: This study included 23 patients with nasopharyngeal carcinoma who had been treated with parotid-sparing radiotherapy (RT). Salivary function was assessed by DW-MRI pre-treatment and one week and one year post-RT, respectively. The maximum apparent diffusion coefficient (ADC) of parotid glands (pADCmax) and the time to peak ADC of parotid glands (pTmax) during stimulation were obtained. Multivariate analysis was used to analyze factors correlated with the severity of radiation-induced xerostomia. RESULTS: The ADCs of parotid and submandibular glands (1.26 ± 0.10 × 10−3 mm2/s and 1.32 ± 0.07 × 10−3 mm2/s pre-RT, respectively) both showed an increase in all patients at one week post-RT (1.75 ± 0.16 × 10−3 mm2/s, p < 0.001 and 1.70 ± 0.16 × 10−3 mm2/s, p < 0.001, respectively), followed by a decrease in parotid glands at one year post-RT(1.57 ± 0.15 × 10−3 mm2/s, p < 0.001) but not in submandibular glands (1.69 ± 0.18 × 10−3 mm2/s, p = 0.581). An improvement in xerostomia was found in 13 patients at one year post-RT. Multivariate analysis revealed 4 significant predictors for the improvement of xerostomia, including dose to parotid glands (p = 0.009, odds ratio [OR] = 0.639), the ADC of submandibular glands (p = 0.013, OR = 3.295), pADCmax (p = 0.024, OR = 0.474), and pTmax (p = 0.017, OR = 0.729) at one week post-RT. CONCLUSION: The ADC value is a sensitive indicator for salivary gland dysfunction. DW-MRI is potentially useful for noninvasively predicting the severity of radiation-induced xerostomia.

Malignant salivary gland tumors only represent 0.08% of all childhood tumors and mucoepidermoid carcinoma (MEC) is the most common histologic type. Although there are many reports describing second malignant neoplasm (SMN) in patients treated for childhood cancer, salivary gland tumors rarely appears. In Korea, there has been no report about MEC that developed in children as a SMN. We report a MEC in a 4 years and 8 months old female child that developed after completing treatment for yolk sac tumor of lower abdomen. The primary tumor presented with metastasis at the time of diagnosis, and therefore, the child underwent high-dose chemotherapy with autologous peripheral blood stem cell transplantation along with surgery and radiotherapy. Three years and five months after completing treatment, MEC developed in her submandibular gland. She was treated with surgery and radiotherapy and is in disease free state for 5 months at the time of this writing.

BACKGROUND: Functional restoration of the facial expression is necessary after facial nerve resection to treat head and neck tumors. This study was conducted to evaluate the functional outcomes of patients who underwent facial nerve cable grafting immediately after tumor resection. METHODS: Patients who underwent cable grafting from April 2007 to August 2011 were reviewed, in which a harvested branch of the sural nerve was grafted onto each facial nerve division. Twelve patients underwent facial nerve cable grafting after radical parotidectomy, total parotidectomy, or schwannoma resection, and the functional facial expression of each patient was evaluated using the Facial Nerve Grading Scale 2.0. The results were analyzed according to patient age, follow-up duration, and the use of postoperative radiation therapy. RESULTS: Among the 12 patients who were evaluated, the mean follow-up duration was 21.8 months, the mean age at the time of surgery was 42.8 years, and the mean facial expression score was 14.6 points, indicating moderate dysfunction. Facial expression scores were not influenced by age at the time of surgery, follow-up duration, or the use of postoperative radiation therapy. CONCLUSIONS: The results of this study indicate that facial nerve cable grafting using the sural nerve can restore facial expression. Although patients were provided with appropriate treatment, the survival rate for salivary gland cancer was poor. We conclude that immediate facial nerve reconstruction is a worthwhile procedure that improves quality of life by allowing the recovery of facial expression, even in patients who are older or may require radiation therapy.

OBJECTIVETo investigate the prognosis of adenoid cystic carcinoma (ACC) in minor salivary glands and its influencing factors.
METHODSClinical data of 52 patients with ACC in minor salivary glands were reviewed. The distribution of stage was as follows: stage I (6%), stage II (21%), stage III (27%) and stage IV (46%). Counting data was analyzed by χ(2) test or Fisher's exact. Survival rates were calculated by Kaplan-Merier method. Statistical significance of differences in the cumulative survival curves was evaluated using the Log-rank test. Multivariate analysis was performed by Cox proportional hazard model.
RESULTSAll patients underwent primary tumor radical resection, 39 patients (75%) received postoperative radiation. The regional recurrence rate was 37% and distant metastasis rate was 21%. The 5-, 10-year cumulative local control rate were 68% and 63% respectively. The 5-, 10-year cumulative distant control rate were 86%, 68% respectively. The 5-, 10-year tumor specific survival rates were 70% and 54% respectively. Multivariate analysis showed that T stage, lymph node metastasis and perineural invasion were relevant to the tumor specific survival of ACC in minor salivary glands.
CONCLUSIONSRecurrence and metastasis were the main cause of treatment failure of ACC in minor salivary glands. T stage, lymph node metastasis and perineural invasion were the independent prognostic factors of ACC in minor salivary glands. Radical surgery and reasonably postoperative radiotherapy were the main treatment strategy.

BACKGROUND AND OBJECTIVES: Parapharyngeal space tumors are extremely rare head and neck tumors. Therefore, there are just a few reports about them. The purpose of this study was to report our experiences of parapharyngeal space (PPS )tumors regarding clinicopathological features and management. SUBJECTS AND METHOD: This study included 51 patients with PPS tumors which were diagnosed from January 1990 through June 2004. Medical records were reviewed retrospectively. RESULTS: The male-to-female ratio was close to 1:1. The mean age was 47 years (6 mo -83 Y ). The most frequent presenting manifestation was asymptomatic neck mass. All patients were subjected to CT scan, while 31 patients underwent MRI in addition. Diagnostic accuracy of fine needle aspiration cytology of 28 cases matched with pathologic reports by 50%. Salivary gland neoplasms occupied the biggest parts (43.1%, 53.8%)of both benign and malignant PPS tumors. Thirteen patients (25.5%)had malignant lesions. Surgical excision was performed in 39 cases (76.5%). The transcervical (30.8%)and the transcervical-transparotid approaches (38.5%)were commonly performed surgical procedures. Overall postoperative morbidity rate was 23.1%. There were 3 recur-rences (42.8%)in malignant tumors and no recurrence in benign ones after surgical excision during the mean follow-up period of 35 months (13 -89 mo ). Close observation, sclerotherapy and radiotherapy were only applicable for a few selected benign lesions. CONCLUSION: Most benign PPS tumors could be removed surgically with low complication and recurrence rates. Optimal surgical approach based on transcervical approach allows safe removal of various types of PPS tumors.
