RESUMO
OBJECTIVES: Identify positive margin rate in a national cohort of patients with submandibular carcinoma, identify predictors of positive margins, and associate margins with overall survival. STUDY DESIGN: Retrospective cohort. SETTING: Commission on Cancer-accredited hospitals. SUBJECTS AND METHODS: We included patients in the National Cancer Database from 2004 to 2014 who were diagnosed with submandibular carcinoma and underwent primary surgical resection. We determined the rate of positive surgical margins and associated patient, tumor, and treatment factors with positive margins via univariable and multivariable logistic regression analysis. We associated margin status with overall survival by Kaplan-Meier curve and Cox proportional hazards regression. RESULTS: We identified 1150 patients with submandibular malignancy undergoing surgical resection. Positive margin rate was 41.0%. Increased odds of positive margins were seen in patients with advanced T stage (vs T1, T3: odds ratio [OR] = 3.04, P < .001; T4a: OR = 2.89, P < .001), adenoid cystic carcinoma histology (OR = 1.54, P = .020), and those treated at nonacademic facilities (OR = 1.41, P = .008). Patients who underwent a preoperative diagnostic biopsy had decreased odds of positive margins (OR = 0.72, P = .014). Positive margins were associated with reduced overall survival (58% vs 69% 5-year overall survival, P < .001; hazard ratio = 1.49, P = .001) when controlling for patient, tumor, and management factors. CONCLUSIONS: The national positive margin rate of submandibular carcinoma is 41.0%. Preoperative biopsy and treatment at academic institutions independently decreased the risk of positive margins, and positive margins were independently associated with diminished overall survival. Positive margin rate for submandibular carcinoma may be considered a benchmark for quality of care.

PURPOSE: Submandibular gland (SMG) carcinoma has an unfavorable clinical course and a low survival rate. Specific tumor and nodal findings might help predict posttreatment recurrence and survival in SMG carcinoma patients. This study evaluated factors predictive of posttreatment recurrence and survival in SMG carcinoma patients. METHODS: This study enrolled 99 consecutive patients with previously untreated SMG carcinoma. All patients underwent tumor and metastatic lymph node resection along with or without radiation/chemo-radiation. The predictive clinical and pathological factors for disease-free survival (DFS), distant metastasis-free survival (DMFS), disease-specific survival (DSS), and overall survival (OS) were determined using univariate and multivariate Cox proportional hazards regression analyses. RESULTS: The median tumor size was 2.7 cm and 53 patients (53.5%) had high-grade tumors. The rates of initial nodal and distant metastasis at initial presentation or follow-up were 45.5% and 42.4%, respectively. The actuarial 5-year DFS, DMFS, DSS, and OS rates were 46.4%, 55.9%, 61.5%, and 59.7%, respectively. The independent factors associated with poor DFS, DMFS, DSS, and OS outcomes (all p < 0.05) were T3-T4 classification and lymph node ratio. A histological high-grade tumor was an independent prognostic factor predictive of poor DMFS, DSS, and OS outcomes (all p < 0.05). CONCLUSIONS: A high rate of distant site failure is associated with SMG carcinoma, resulting in a poor survival rate. Lymph node ratio might help predict recurrence, distant metastasis, and death due to SMG carcinoma.

INTRODUCTION: To investigate whether the positive lymph node number (PLNN) and positive lymph node ratio (PLNR) could predict the prognosis of patients with major salivary gland cancer (MSGC) and to identify the optimal cutoff points for these variables that stratify patients according to their risk of survival. METHODS: We used the Surveillance, Epidemiology, and End Results (SEER) database to identify all patients with MSGC between 1988 and 2014. A logistic regression analysis was carried out to evaluate the risk factors for lymph node metastasis (LNM) in MSGC. The X-tile program was used to identify the cutoff values for the PLNN and PLNR in MSGC patients with LNM. Cox proportional hazards regression models were performed to identify the predictors of cancer-specific survival (CSS). RESULTS: In the SEER database, 8668 eligible patients were identified and 3046 of them had LNM. The logistic regression analysis indicated that older age, male sex, larger tumor size, higher grade, tumor extension and high-risk pathology were associated with LNM. The X-tile program showed that a PLNN>4 and a PLNR>0.15 were prognostic indicators of CSS. A multivariable analysis indicated that, after the factors that might potentially affect the prognosis were adjusted for, the PLNN and PLNR were still associated with CSS. CONCLUSIONS: Our Results demonstrated that the PLNN and PLNR were independent prognostic indicators for MSGC patients with lymph node metastasis.

OBJECTIVES/HYPOTHESIS: Submandibular gland tumors (SMGTs) are rare and characterized by heterogeneity in histologic profiles. The aim of the present study was to retrieve data on submandibular gland (SMG) malignancies and identify factors influencing survival. STUDY DESIGN: Retrospective study. METHODS: A multicenter, retrospective study on patients who underwent primary surgery for SMGTs at three referral centers was performed. RESULTS: Among 204 patients with SMGTs, 50 (24.5%) with SMG malignancies were analyzed in detail. Definitive pT status was: 21 (42%) pT1, 14 (28%) pT2, 10 (20%) pT3, and five (10%) pT4. Nodal metastases and perineural spread were diagnosed in 15 (30%) and 25 (50%) patients, respectively. High-grade lesions were identified in 32 (64%) patients. Follow-up status, available for 49 (98%) patients, was as follows: 23 (47%) patients were alive without disease, 11 (22.5%) died of disease, five (10.2%) alive with disease, and 10 (20.4%) died of other causes. Five- and 10-year overall survival (OS), disease-specific survival (DSS), and recurrence-free survival (RFS) were 66.4% and 57.1%, 76.6% and 72.1%, 69.1% and 62.4%, respectively. At univariate analysis, OS, DSS, and RFS were influenced by pT status, pN status, and perineural spread. OS and RFS were also affected by the presence of facial palsy and pain. RFS was negatively influenced by positive margins. Multivariate analysis confirmed that OS, DSS, and RFS were independently affected by perineural spread, whereas nodal involvement influenced only RFS. CONCLUSIONS: The malignancy rate of SMGTs is comparable to that reported for parotid tumors. Most patients presented with high-grade lesions. pT status, pN status, and perineural spread significantly affected prognosis. LEVEL OF EVIDENCE: 4 Laryngoscope, 128:2745-2750, 2018.

Objective: In this study, patients with head and neck adenoid cystic carcinoma were investigated with respect to disease characteristics, treatments, and potentially prognostic variables. Materials and Methods: Between January 1995 and December 2010, 29 patients with ACC of the head and neck treated at our institution were retrospectively reviewed. Results: The 29 patients had a mean age of 54.7 years. Of the 29 patients, 4 (13.8%) underwent surgical resection only, 21 (72.4%) underwent surgery with radiotherapy, and 4 (13.8%) received postoperative chemoradiotherapy. Of 9 patients (31.0%) who experienced a recurrence within the follow-up period, 3 (10.3%) had local recurrence and 5 (17.2%) had distant metastasis; 1 (3.4%) patient had both local recurrence and distant metastatic spread. Conclusion: ACC is a relatively rare tumor associated with long survival, even in metastatic settings. Despite aggressive therapy with surgery, radiotherapy, and chemo- therapy, a marked potential for local and distant recurrence still remains.

OBJECTIVE: Clinical studies demonstrating the prognostic factors in submandibular gland carcinoma are limited because the tumor is relatively rare. The aim of this study was to identify clinical outcomes and prognostic factors in submandibular gland carcinoma. METHODS: The study included 65 patients with submandibular gland carcinoma who underwent initial surgical treatment at the Kyoto University and its affiliated hospitals. RESULTS: The 3-year overall survival (OS), disease specific survival, locoregional control (LRC), and no distant metastasis (NDM) rates were 74.2%, 74.2%, 90.0%, and 64.8%, respectively. In the current follow-up study, 16 patients died of the disease, 5 patients were alive with recurrence, 43 patients were alive without disease, and 1 patient died of unrelated disease without recurrence. All patients who died of the disease had developed distant metastasis. Based on univariate analysis, tumor grade (high grade) and lymph node metastases (≥N2) were significant prognostic factors for OS and LRC. It also revealed tumor grade (high grade), T classification (≥T3), and lymph node metastases (≥N2) were significant for distant metastasis. Multivariate analysis showed the following significant prognostic factors: lymph node metastases (≥N2) for OS, LRC, and NDM, and high tumor grade for NDM. CONCLUSION: Our study suggested death of submandibular gland carcinoma occurred mainly due to distant metastasis. The significant predictors of distant metastasis were lymph node metastases (≥N2) and tumor grade (high grade).

BACKGROUND: In the absence of unified treatment protocol, we evaluated the management and outcomes of submandibular gland cancers in an unselected patient series. METHODS: We included all patients with resected submandibular gland cancer treated at the Helsinki University Hospital from 2000 to 2010 with a 5-year minimum follow-up. RESULTS: Twenty-five patients with cancer represented 30% of submandibular gland neoplasms, and most were adenoid cystic carcinomas (ACCs; 56%). At presentation, 3 patients showed clinical signs of probable malignancy. Of 22 neck dissection specimens, 5 patients (20%) had metastases with an occult metastasis rate of 4%. Cancer recurred in 11 patients (44%), of which 7 (28%) were only at a distant site. The 5-year disease-specific survival (DSS) and overall survival (OS) rates were 76%, and disease-free survival (DFS) was 68%. CONCLUSION: Most tumors were ACCs differing from the histological pattern of parotid gland cancers. Occult metastases were rare. The rarity of submandibular gland cancer, its variable histological pattern, and varying biological behavior warrant centralized management.

BACKGROUND: Roughly half of submandibular gland neoplasms are malignant. Because preoperative information on the nature of these tumors remains limited, both preoperative evaluation and assessment of the extent of primary surgery warrant guidelines that are more accurate. METHODS: We evaluated the preoperative examinations and management of all submandibular gland neoplasms treated surgically at the Helsinki University Hospital between 2000 and 2010. RESULTS: Of the 83 tumors, 58 (70%) were benign and 25 (30%) were malignant. Of the benign tumors, 54 (93%) were pleomorphic adenomas. The cytology in 8 patients (10%) was class IV or V, and in 12 patients was class III; the tumors in 9 of these 12 patients turned out to be malignant. Of all malignancies, 10 (40%) required additional more extensive surgery. CONCLUSION: Ultrasound-guided fine-needle aspiration cytology (FNAC) proved useful, with limitations, in preoperative examination. Surgeons should always obtain wide margins whenever possible, even when clinical means or cytology indicates no malignancy. © 2017 Wiley Periodicals, Inc. Head Neck 39: 1071-1077, 2017.

OBJECTIVE: Major salivary gland large-cell undifferentiated carcinoma (LCUC) is rare and has a poor prognosis. Characterization of patient demographics, tumor characteristics, and predictors of outcome have been limited by low case numbers, as well as grouped analysis with other salivary malignancies. The objective of this study was to address these issues using large-scale national data. STUDY DESIGN: Retrospective case series. METHODS: Data from the National Cancer Database, including cases diagnosed from 1998 to 2012, was analyzed, identifying 247 records of LCUC. Tumor, demographic, and survival information was extracted and analyzed retrospectively. RESULTS: Large-cell undifferentiated carcinoma comprised < 1% of all major salivary gland cancers. Seventy percent of patients presented with advanced-stage disease. The incidence of occult nodal disease was 39%. Surgery followed by radiation was the most common treatment. Five-year overall survival was 36%. Comorbidity, distant metastasis, and positive surgical margins were found to be predictors of overall survival. CONCLUSION: To our knowledge, this represents the largest reported case series of LCUC. The survival analysis demonstrates poorer survival in patients with positive surgical margins; therefore, efforts to complete resection are reasonable. Reported high rates of occult nodal disease also strongly support elective treatment of the neck. LEVEL OF EVIDENCE: 4. Laryngoscope, 2016 127:372-376, 2017.

BACKGROUND: The clinical behavior and treatment outcomes of salivary gland myoepithelial carcinoma have yet to be clearly defined. The current study investigated risk factors and prognoses for this tumor. METHODS: A retrospective review of the medical records for 32 patients with myoepithelial carcinoma of the major salivary glands was performed. Their clinical parameters were assessed to identify correlations with local-regional recurrence, distant metastasis, and survival. RESULTS: The 5-year survival rate was 71 %. Of the reviewed patients, 41 % had local-regional recurrences, and 22 % had distant metastases. Age of 60 years or younger was a predictive factor for distant metastasis. Patients with neck lymph nodes clinically positive for carcinoma had shorter overall survival durations than those with nodes negative for carcinoma. CONCLUSIONS: Myoepithelial carcinoma of the major salivary glands is characterized by a high incidence of local-regional recurrence and distant metastasis. Adjuvant therapy is indicated for selected patients with high-risk disease.

BACKGROUND: The purpose of this study was to reveal prognostic factors for surgical complications and survival in young and elderly patients with malignant salivary gland tumors. METHODS: Retrospective analysis of surgically treated patients with malignant major salivary gland tumors was performed. Of the 111 patients, 33 patients were 70 years or older and 78 patients were under 70. Comorbidity was recorded using the Adult Comorbidity Evaluation-27 index and complications using the Clavien-Dindo classification. RESULTS: Comorbidity and complications were significantly more frequent in elderly patients (p < .05). Age, comorbidity, and length of surgery were not significant independent predictors of complications. Stage was the only independent predictive factor for postoperative complications and disease-specific survival. CONCLUSION: Based on this retrospective analysis reviewing surgically treated patients, age alone should not be a reason to treat elderly patients differently, as it was not a predictor of either complications or disease-specific survival.

BACKGROUND AND OBJECTIVES: Little is known about lymph node metastasis and the extent of neck dissection (ND) in patients with submandibular gland (SMG) carcinoma. We therefore evaluated the metastatic topography of neck lymph nodes in patients with SMG carcinoma and the influence of metastases on tumor recurrence and patient survival. METHODS: The pattern of lymph node spread was analyzed in 64 patients with SMG carcinoma treated from January 1994 to January 2009. Disease-free survival (DFS), overall survival (OS), and distant metastasis-free survival (DMFS) were calculated, and the clinicopathological factors associated with each were analyzed. RESULTS: Positive pathological lymph nodes were detected in 31 (48.4%) patients and was found to correlate significantly with histologic grade (P<0.001) on univariate analysis. Eight patients (19.5%) had occult cervical metastases. The 5-year DFS, OS, and DMFS rates were 46.8, 56.2, and 58.5%, respectively, and 23 patients (35.9%) experienced systemic failure. Multivariate analyses revealed that T-classification (P=0.043) and N-classification (P=0.006) were significantly independent predictors of DFS, whereas only N-classification (P=0.049) was significantly associated with DMFS. CONCLUSIONS: Elective ND should be recommended for preoperatively suspected high-grade malignancy in SMG carcinoma. Patients with nodal metastasis should receive more effective therapy to hinder recurrence and distant metastasis.

BACKGROUND: Adenoid cystic carcinoma (ACC) of the head and neck (ACCHN) is a rare tumor of minor salivary, parotid, and submandibular glands. The biologic behavior of the disease is poorly understood, and nonsurgical treatment strategies have yet to be standardized. The long-term prognosis continues to be guarded, with an estimated 10-year survival of <60%. Population-based studies examining ACC are scarce. The authors aimed to analyze incidence rates and survival outcomes for patients diagnosed with ACCHN using national population-based data. METHODS: Data were obtained from the US National Cancer Institute's Surveillance, Epidemiology, and End Results (SEER) program. Newly diagnosed ACCHN cases reported to SEER from 1973 through 2007 were categorized according to their sex, race, age, year of diagnosis, marital status, treatment interventions, primary tumor site, and disease stage. Incidence of ACCHN and postdiagnosis survival were examined over time and compared across different demographic and disease-related categories. RESULTS: The authors identified 3026 patients with ACCHN. The mean age at diagnosis among those cases was 57.4 years (range, 11-99 years). Analyses of incidence data demonstrated a decline in ACCHN rates between 1973 and 2007, noted across all sexes and races with no detectable inflexion points. The overall 5-year, 10-year, and 15-year survival outcomes for ACCHN patients were 90.3%, 79.9%, and 69.2%, respectively. Females, patients with localized disease, and younger patients were found to have significantly better survival across all time periods (all comparison-specific log-rank P values <0.001). Multivariate analyses revealed better prognosis among women compared with men (hazard ratio [HR], 0.73; 95% confidence interval [CI], 0.65-0.82), among married compared with unmarried individuals (HR, 0.81; 95% CI, 0.71-0.91), with certain sites of origin and stage of disease (HR, 2.788; 95% CI, 2.36-3.29), and in those who had surgery of the primary tumor site (HR, 0.45; 95% CI, 0.37-0.54). CONCLUSIONS: The overall incidence of ACC is declining. The noted differences in survival based on sex, marital status, site of origin, and treatment intervention require further investigation.

PURPOSE: Involvement of salivary glands with mucosa-associated lymphoid tissue (MALT) lymphoma is rare. This retrospective study was performed to assess the clinical profile, treatment outcome, and prognostic factors of MALT lymphoma of the salivary glands. METHODS AND MATERIALS: Thirteen member centers of the Rare Cancer Network from 10 countries participated, providing data on 63 patients. The median age was 58 years; 47 patients were female and 16 were male. The parotid glands were involved in 49 cases, submandibular in 15, and minor glands in 3. Multiple glands were involved in 9 patients. Staging was as follows: IE in 34, IIE in 12, IIIE in 2, and IV in 15 patients. RESULTS: Surgery (S) alone was performed in 9, radiotherapy (RT) alone in 8, and chemotherapy (CT) alone in 4 patients. Forty-one patients received combined modality treatment (S + RT in 23, S + CT in 8, RT + CT in 4, and all three modalities in 6 patients). No active treatment was given in one case. After initial treatment there was no tumor in 57 patients and residual tumor in 5. Tumor progression was observed in 23 (36.5%) (local in 1, other salivary glands in 10, lymph nodes in 11, and elsewhere in 6). Five patients died of disease progression and the other 5 of other causes. The 5-year disease-free survival, disease-specific survival, and overall survival were 54.4%, 93.2%, and 81.7%, respectively. Factors influencing disease-free survival were use of RT, stage, and residual tumor (p < 0.01). Factors influencing disease-specific survival were stage, recurrence, and residual tumor (p < 0.01). CONCLUSIONS: To our knowledge, this report represents the largest series of MALT lymphomas of the salivary glands published to date. This disease may involve all salivary glands either initially or subsequently in 30% of patients. Recurrences may occur in up to 35% of patients at 5 years; however, survival is not affected. Radiotherapy is the only treatment modality that improves disease-free survival.

BACKGROUND: Malignant submandibular gland tumours are rare tumours treated primarily with surgery. PURPOSE: This retrospective study was done to determine the effectiveness of adjuvant radiation therapy (RT), to document the patterns of failure, and to define the prognostic variables for treatment outcome. MATERIALS AND METHODS: Between 1960 and 2002, 74 patients diagnosed as having malignant submandibular gland tumours were treated with radical surgery. The surgery included neck dissection in 37 patients and adjuvant RT in 50 patients with high-risk features. RESULTS: Forty-one (54%) patients experienced disease relapse. The local recurrence rates were 35% in those treated only with surgery and 21% in patients who underwent postoperative RT (p â=â .20). The risk of subclinical nodal metastases in the clinical N0 neck was 21%. CONCLUSIONS: The American Joint Committee on Cancer stage approached statistical significance for cause-specific survival. Although not statistically significant, RT probably reduced local recurrence. All patients with malignant submandibular tumours except T1 need elective neck treatment.

Previous research has shown that salivary gland tumors are rare in the young population. A clinical diagnosis has to be made very carefully because the proportion of malignancies is higher in children than in adults. We present a review of cases of malignant salivary gland carcinoma (SGC) in patients younger than 30 years of age. Data were extracted from the Surveillance, Epidemiology, and End Results (SEER) 17 Registry. A total of 763 patients younger than 30 years with carcinoma of a major salivary gland from 1973 to 2004 were identified within the SEER database. The most common salivary gland cancer was mucoepidermoid parotid gland carcinoma. The incidence of all major salivary gland carcinomas increased with increasing patient age. The 5-year relative survival rate for salivary gland carcinomas in our population was calculated according to the Kaplan-Meier analysis in each age group. Relative 5-year survival was 100% in the 1 patient younger than 1 year, 50.0% in the 1- to 4-year-old group; 87.2% among the 5- to 9-year-olds; 97.0% among the 10- to 14-year-olds; 95.0% among the 15- to 19-year-olds; 95.1% among the 20- to 24-year-olds; and 93.6% in the 25- to 29-year-old group. We found that SGC affects patients of all ages, even children in the first year of life. It is essential for physicians to detect salivary gland neoplasms promptly and to evaluate them thoroughly when they are found in children.

BACKGROUND: To determine the effects of patient demographics, socioeconomic status (SES) and clinical variables on outcomes for patients with salivary and parotid gland tumors. METHODS: Florida cancer registry and inpatient hospital data were queried for cancer of the salivary glands diagnosed between 1998-2002. RESULTS: A total of 1573 patients were identified. Women were diagnosed at a younger age (median age (years): women 60.8 versus men 64.3, P=0.003). Men were more often diagnosed with high grade tumors (65.1% versus 41.9% for women, P<0.001) and advanced disease stage (>stage III: 60.2 versus 49.4%, P<0.001), but underwent surgical extirpation and received radiation at equal rates compared with women. Overall 5-year survival rates was superior in women (67.4% versus 55.6%, P=0.001). By multivariate analysis, adjusted for patient comorbidities, age over 65 (HR 3.43 P=0.008), advanced disease stage (HR 8.05 P<0.001), and high tumor grade (HR 2.33, P<0.001) were independent predictors of worse prognosis. Improved outcomes were observed for female gender (HR 0.68, P=0.011). Tumors located in the parotid gland (HR 0.631 P=0.003) and receiving both surgical extirpation and radiation were predictors of improved survival. CONCLUSION: Salivary gland tumors carry a worse prognosis than tumors of the parotid. Male patients have worse outcomes.

OBJECTIVES: The study was performed to evaluate the prognostic relevance of cell proliferation associated with Ki-67/ Mib-1 immunostaining in malignant tumors of the major salivary glands. METHODS: Cell proliferation was evaluated by Mib-1 antibody against Ki-67 antigen in 41 patients with cancer of the parotid or submandibular glands, including 14 acinic cell carcinomas, 12 ductal carcinomas, 7 mucoepidermoid carcinomas, 5 carcinomas ex pleomorphic adenoma, 1 adenoid cystic carcinoma, 1 undifferentiated carcinoma, and 1 polymorphous low-grade adenocarcinoma. RESULTS: Patients with Ki-67 values of more than 15% and those with Ki-67 values of 15% or less differed both in disease-free survival (p < 0.001) and in overall survival (p < 0.001). We evaluated the association between Ki-67 and time to recurrence in correlation to age, sex, ductal histotype, and N stage; the Cox regression model was significant (p = 0.013). In the group of patients with T1 and T2 cancers, those with Ki-67 values of 15% or less had better survival rates than did those with Ki-67 values of more than 15% (p = 0.004). In the group of patients with N0 cancers, those with Ki-67 values of 15% or less had a better survival than did those with Ki-67 values of more than 15% (p < 0.001). CONCLUSIONS: To our knowledge, this is the first study to stratify different risk classes in early T1-T2 or N0 malignant tumors of the major salivary glands that identified aggressive lesions with elevated Ki-67 expression at an initial stage.

BACKGROUND: Cancers of the submandibular gland are uncommon and only a few small series have reported patient survival and prognosis. METHODS: We examined the treatment outcomes of 62 patients with surgically treated submandibular gland carcinomas. All patients underwent surgical excision with/without neck dissection, and 41 received postoperative radiotherapy for high-grade, invasive, positive margin, or regionally metastatic tumors. The locoregional control and survival rates were calculated by the Kaplan-Meier method and prognostic factors were calculated from uni- and multivariate analyses. RESULTS: Of the 62 submandibular gland carcinomas, 19 were adenoid cystic, 11 were mucoepidermoid, and 10 were salivary duct carcinomas, and 8 were carcinomas in pleomorphic adenoma. Actuarial 5-year locoregional control, distant metastasis-free survival, disease-free and overall survival rates were 69.7%, 65.8%, 52.8%, and 56.8%, respectively. In multivariate analysis, T category and histological grading were prognostic for disease-free survival (P < 0.01), and T category and resection margins were prognostic for locoregional control (P < 0.02). Distant metastases were found in 21 patients (33.9%) at initial staging (n = 2) or follow-up (n = 19). CONCLUSIONS: Despite effective locoregional treatment, approximately one-third of patients with submandibular gland carcinomas may fail systemically, resulting in poor survival. New, more effective therapies may be required for these patients.

BACKGROUND & OBJECTIVE: Adenoid cystic carcinoma of salivary glands is a kind of highly malignant tumor, and researches on the tumors originated from major salivary glands are rare. This study was to investigate prognostic factors of adenoid cystic carcinoma of major salivary glands. METHODS: Clinical records of 64 patients with adenoid cystic carcinoma of major salivary glands followed up for more than 7 years were reviewed. Cumulative survival rate was analyzed by the Kaplan-Meier method. The log-rank test was applied to compare survival rates, and the comparison of the percentage of subjects between two groups was conducted with Chi2 test. RESULTS: The overall death rate was 57.8%; the cause-specific death rate was 46.9%; the 5-and 10-year cumulative survival rates were 65.63% and 54.52%, respectively; the relapse rate was 34.4%; and the metastasis rate was 45%. Univariate analysis revealed that the factors impacting the prognosis were age, presence or absence of nerve invasion, histological subtypes, clinical stage, positive or negative surgical margin. Patients aged > or = 50, presence of nerve invasion, solid/tubular subtype, advanced clinical stage (stages III and IV), and positive surgical margin had poorer prognosis than those aged < 50, absence of nerve invasion, cribriform subtype, early clinical stage (stages I and II), and negative surgical margin. Multivariate analysis showed that the presence of nerve invasion, solid histological subtype, advanced clinical stage (stages III and IV), and positive surgical margin were independently associated to poor prognosis. CONCLUSION: Presence or absence of nerve invasion, histological subtype, clinical stage, and positive or negative surgical margin are the independent factors affecting the prognosis of patients with adenoid cystic carcinoma of salivary glands.
