Abstract
Oral tongue squamous cell cancer (OTSCC) is one of the most prevalent cancers worldwide and incidence increases with age. An alarming increase in the incidence of OTSCC in the younger age group. This study aimed to explore clinical and histopathological characteristics, survival, and other post-surgical outcomes in patients with OTSCC treated with glossectomy through the Department of Otolaryngology-Head & Neck Surgery at the Ministry of National Guard Health Affairs (MNGHA) within our study period. This is a retrospective study carried out through the collection and analysis of data from medical charts of 56 patients with oral tongue cancer who were treated by glossectomy. Treatment was initiated from January 2010 to December 2021. Patient characteristics, tumor characteristics, treatment modality, failure patterns, and survival rates were collected and analyzed. At diagnosis, 62.5% were tobacco smokers, 46.8% had poor dental hygiene, and 76.8% had ulcerative lesions. Furthermore, 33 cases presented with early-stage clinical disease and 23 cases with advanced stage. The median follow-up was 54 months, 28 patients (50%) were free for 3-5 years. Patients who were free on 5-year follow-up had a significantly higher percentage of negative lymphovascular and perineural invasion (p < 0.05). Additionally, 12 patients (21.4%) had developed recurrence. Mortality in all cases was 30.3, but mortality-related cancer was 19.6%. Locoregional failure remains the main cause of treatment failure in resectable OTSCC. Pathological T-stage, N-stage, LVI, PNI, ECE, and LNR are all considered strong prognostic factors.

Oncologic Outcome in Advanced Oral Squamous Cell Carcinoma After Refusal of Recommended Adjuvant Therapy. JAMA Otolaryngol Head Neck Surg 2023; 149:1027-1033. [PMID: 37824130 PMCID: PMC10570914 DOI: 10.1001/jamaoto.2023.3111] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/14/2023] [Accepted: 08/28/2023] [Indexed: 10/13/2023]
Abstract
Importance Clinicians may be confronted with patients refusing recommended adjuvant therapy (AT) after the primary resection of an advanced oral squamous cell carcinoma (OSCC). However, for this tumor entity, data are lacking regarding the oncological outcomes and associated factors after refusal of AT. Objective To evaluate the difference in survival and disease recurrence for patients with and without recommended AT after resection of advanced OSCC. Design, Setting, and Participants In this single-center retrospective matched cohort study, patients with advanced OSCC who refused recommended AT between January 2010 and December 2021 were matched 1:1 according to Union for International Cancer Control tumor staging with patients who completed AT. Exposures Patients with advanced OSCC who refused or completed recommended AT between 2010 and 2021. Main Outcomes and Measures The primary outcome of this study was the comparison of overall survival (OS) and recurrence-free survival (RFS) between the 2 study groups. Results A total of 82 patients (mean [SD] age at time of surgery, 68.0 [11.3] years; 38 [46.3%] female, 44 [53.7%] male) with and without AT (41 per study group) were included in the analysis. Patients refusing AT developed more frequent disease recurrence than patients who completed AT (61.0% vs 26.8%; difference, 34.2%; odds ratio, 4.26; 95% CI, 1.68-10.84). In addition, patients who refused AT presented with lower 2-year OS (72.7% vs 88.6%; difference, 15.9%; 95% CI, 8.6%-40.6%) and much lower 2-year RFS (39.1% vs 74.2%; difference, 35.1%; 95% CI, 0.2%-70.5%). In the patient cohort who rejected AT, a worse OS was associated with female sex (48.6% vs 90.5%; difference, 41.9%; 95% CI, 0.6%-84.4%), pT1-2 category (57.1% vs 92.3%; difference, 35.2%; 95% CI, 3.3%-73.6%), and pN1 or higher category (61.2% vs 82.6%; difference, 21.4%; 95% CI, 14.1%-56.8%). Lower RFS was associated with female sex (37.9% vs 90.9%; difference, 53.0%; 95% CI, 8.0%-97.9%), advanced T category (pT3-4, 35.3% vs 80.0%; difference, 44.7%; 95% CI, 6.4%-95.3%), lymph node yield of 20 or greater (31.4% vs 80.6%; difference, 49.2%; 95% CI, 4.9%-93.4%), and lymph node ratio of less than 4.6% (36.6% vs 84.4%; difference, 47.8%; 95% CI, 1.8%-93.1%). Conclusions and Relevance In this cohort study of patients with advanced OSCC, refusal of AT was associated with worse oncological outcomes. The prevalence of disease recurrence during follow-up was 34% higher in patients who refused AT than in patients who completed AT. The results from this study may assist clinicians in guiding patients who are considering refusal of or withdrawal from AT.

Temporal trends of women with oral cavity, base of tongue and lip cancers in Brazil: An ecological study covering mortality data from 1980 to 2018. Community Dent Oral Epidemiol 2023; 51:236-246. [PMID: 35156217 DOI: 10.1111/cdoe.12731] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/31/2021] [Revised: 10/09/2021] [Accepted: 01/18/2022] [Indexed: 12/24/2022]
Abstract
OBJECTIVES Obtaining robust evidence about the local mortality levels, trends and impact of oral cavity/base of tongue cancers and lip cancer, especially for women, is imperative in the fight against cancer. This descriptive retrospective ecological time-series study explored trends in oral cavity/base of tongue cancers and lip cancer mortality rates for women in Brazil from 1980 to 2018, by geographic region and anatomical location. METHODS The crude and age-adjusted annual mortality rates were obtained by sex, anatomical location and macro-regions of Brazil. The number of deaths from oral cavity/base of tongue cancers and lip cancers in Brazil was based on official population counts and estimates. The annual percentage change was calculated based on age-adjusted rates. Data set were analysed using the Joinpoint Regression program. RESULTS A total of 81,918 individuals died of oral cavity/base of tongue cancers and lip cancer between 1980 and 2018 in Brazil. The age-adjusted mortality rate for women was 0.47 and 0.57 per 100,000 in 1980 and 2018, respectively. The cumulative female mortality rates standardized by age were 0.01/100,000 for lip cancer and 0.5/100,000 for oral cavity and base of tongue cancers. A decrease in deaths related to oral cavity and base of tongue cancers was identified in the 1980s; however, over the last two decades, there has been an increase in the number of deaths of women with cancer at the base of tongue and neighbouring areas and on the floor of mouth. Importantly, Brazilian regions showed wide variability in trends of oral cavity, base of tongue and lip cancers rate and, in 2018, the regions with the highest rates were the Southeast, South and Northeast for both sexes and specifically for women. The North region showed the greatest recent significant upward trend. CONCLUSIONS During the last 38 years, Brazil has shown a significant increase in the trend of the mortality rate due to oral cavity/base of tongue and lip cancers in women. Preventive strategies with control of risk factors should be strongly emphasized in order to improve the survival rates of individuals with oral cavity/base of tongue and lip cancers.

Abstract
OBJECTIVE To analyse the trend in the percentage of patients with squamous cell carcinoma of the head and neck (SCCHN) of female gender over the last decades, and differences in survival according to gender. MATERIAL AND METHODS Retrospective study of 5828 SCCHN diagnosed during the period 1985-2019. In the survival analysis we only included only patients with more than two years of follow-up. RESULTS The proportion of tumours in female patients increased significantly over the study period. There was greater increase of tumours located in the oral cavity, oropharynx and larynx in the percentage of female patients. When considering the total number of patients, there were no significant differences in disease-specific survival according to gender. We observed a variable behaviour of disease-specific survival according to gender depending on the primary location of the tumour. For tumours of the larynx and oropharynx the female patients had a disease-specific survival significantly higher than that of men, while for tumours of the oral cavity, the female patients had a significant reduction of disease-specific survival. CONCLUSIONS In our setting, the percentage of female patients with HNSCC has been increasing steadily over recent decades. There were differences in disease-specific survival according to gender depending on the location of the primary tumour.

Abstract
PURPOSE There is sparse literature on treatment outcomes research on resectable oral tongue squamous cell carcinoma (OTSCC). The aim of this study was to measure the treatment outcomes, explore the failure patterns, and identify the potential clinicopathological prognostic factors affecting treatment outcomes for resectable OTSCC. MATERIALS AND METHODS It is a retrospective analysis of 202 patients with resectable OTSCC who underwent upfront primary surgical resection followed by adjuvant radiotherapy with or without concurrent chemotherapy if indicated. RESULTS The median follow-up was 35.2 months (range, 1.2 to 99.9 months). The median duration of locoregional control (LRC) was 84.9 months (95% confidence interval, 67.3-102.4). The 3- and 5-year LRC rate was 68.5% and 58.3%, respectively. Multivariate analysis showed that increasing pT stage, increasing pN stage, and the presence of extracapsular extension (ECE) were significantly associated with poorer LRC. The median duration of overall survival (OS) was not reached at the time of analysis. The 3- and 5-year OS rate was 70.5% and 66.6%, respectively. Multivariate analysis showed that increasing pT stage and the presence of ECE were significantly associated with a poorer OS. CONCLUSION Locoregional failure remains the main cause of treatment failure in resectable OTSCC. There is scope to further improve prognosis considering modest LRC and OS. Pathological T-stage, N-stage, and ECE are strong prognostic factors. Further research is required to confirm whether adjuvant therapy adds to treatment outcomes in cases with lymphovascular invasion, perineural invasion, and depth of invasion, and help clinicians tailoring adjuvant therapy.

Abstract
OBJECTIVE To describe the demographics, tumor characteristics, and prognostic features of mucoepidermoid carcinoma of the parotid gland. MATERIALS AND METHODS A retrospective study of the National Cancer Database was reviewed for all mucoepidermoid carcinomas of the parotid gland between 2004 and 2012). Patient demographics and tumor characteristics were abstracted and analyzed. Univariate and multivariate Cox multivariate regression models were used to identify predictors of survival. RESULTS A total of 4431 patients met inclusion criteria. Average age at diagnosis was 57 years (median 62, SD 19), with no overall sex preference (52% female), and majority white (78%). The 1-year overall survival was 92.9% (95% CI [92.1-93.6]) and 5-year overall survival was 75.2% (95% CI [73.8-76.7%]). Median overall survival was not reached at 5 years. Factors associated with decreased survival were increasing age, comorbidities, high tumor grade, advanced pathologic group stage, and positive surgical margins. Female sex was the only factor associated with improved survival. Controlling for either histopathologic grade or pathologic stage to determine how patient demographics and tumor characteristics affected overall survival yielded similar results. Of note, intermediate grade tumors, although not independently associated with worse survival, when seen in conjunction with tumors ≥T2 and/or ≥N2, a negative impact on overall survival was seen. CONCLUSION Although mucoepidermoid carcinoma of the parotid gland is the most common parotid gland malignancy, it is still a rare tumor with a lack of large population-based studies. Advanced stage and high-grade tumors are significant predictors of decreased survival. Females have improved survival compared to males.

Abstract
PURPOSE To investigate the effect of race and sex on long-term survival of oral and oropharyngeal cancer. METHODS The Surveillance, Epidemiology and End Results database was queried for adult oral and oropharyngeal cancer patients with at least 25-year follow-up. Kaplan-Meier survival curves and cox proportional hazards model were used to identify differences. RESULTS Of the 22,162 patients identified, 70.3% were males. Only 8.9% were alive at 25 years post-diagnosis. Black males show the poorest overall and disease-specific survival rates (p < 0.001). After controlling for covariates, Blacks had a 40% higher hazard of mortality compared with Whites (HR 1.40, 95% CI 1.35-1.46), while females had a 9% reduction in mortality risk (HR 0.91, 95% CI 0.88-0.94). CONCLUSIONS Overall and disease-specific survival is poor for oral and oropharyngeal cancer patients, and Black men fare worst. This illustrates the need for long-term cancer survival plans incorporating disparity effects in overall cancer outcomes.

Abstract
Introduction: Oral cancer is the sixth most common malignancy in the world, and the third most common in southeast Asia. Cancers of the upper gingivo-buccal complex are uncommon and reported infrequently. In this article, we have assessed the clinicopathological features of such cancers and their optimal management. Materials and Methods: We studied 64 patients with cancer of the upper gingivobuccal sulcus (GBS), hard palate, and maxilla seen between February 2009 and 2013 over a span of 4 years. Results: Of the 64 patients studied, 45 were male. The mean age at presentation was 50.59 years (24-80 years). Of the 64, 48 patients (75%) had a history of substance abuse in the form of tobacco chewing, smoking or alcohol. On presentation, 48 of the 64 patients (75%) had T4 disease, eight had T3, six had T2 lesion, one had T1 lesion, and 1 patient had a neck recurrence with distant metastatic disease (Tx). Out of the 64 patients, 31 had clinically palpable neck disease and two patients had distant metastatic disease. Of the 64 patients, 58 had squamous cell carcinoma, two had adenoid cystic carcinoma of the hard palate and one patient each had melanoma, sarcoma, neuroendocrine tumor, and mucoepidermoid carcinoma. Following imaging, 18 patients (28.13%) underwent upfront surgery and six following neoadjuvant chemotherapy. 14 of the 24 patients operated had simultaneous neck dissection. 2 patients with distant metastasis and 1 with cavernous sinus thrombosis received palliative chemotherapy. Out of the 64 patients, the other 24 who were inoperable were referred to radiotherapy. Conclusion: Upper GBS, hard palate and maxilla cancers are uncommon and are diagnosed at an advanced stage due to delay in presentation and ignorance of our population. Surgery offers the best form of treatment. NACT may be tried to downstage the disease in selected patients with borderline operable disease. However, generous margins should be taken post chemotherapy with concomitant neck dissection. Adjuvant radiotherapy is recommended in selected patients after surgery.

Abstract
The possibility that endocrine factors may influence the clinical course of malignant melanoma is suggested by the superior survival data of women. In preclinical models we observed a higher rate of colony formation by human melanoma cells in male compared to female SCID mice, but only in the case of the liver and not in other organs. The gender difference could be seen at an early phase of colony formation. On the other hand, in our human melanoma cell lines we failed to detect steroid receptor protein expression, and treatment with sex hormones did not considerably influence their in vitro behavior. Investigating the possible contribution of host cells to the observed gender difference, we performed in vivo blocking experiments applying pretreatment of the animals with Kupffer cell inhibitor gadolinium chloride and the NK cell inhibitor anti-asialo GM1 antibody. While Kupffer cell blockade enhanced melanoma liver colonization equally in the two sexes, a more prominent increase was observed in female than in male mice in the case of NK cell inhibition. Further supporting the importance of NK cells in the lower liver colonization efficiency of melanoma cells in females, gender difference in colony formation was lost in NSG mice lacking NK activity. Although in humans no organ selectivity of gender difference in melanoma progression has been observed according to data in the literature, our results possibly indicate a contribution of natural host defense mechanisms to gender difference in survival of patients with melanoma or other tumor types as well.

Abstract
PURPOSE It is unknown whether there are survival disparities between men and women with squamous cell carcinoma of the head and neck (SCCHN), although some data suggest that men have worse outcomes. We conducted a matched-pair study that controlled for several potentially confounding prognostic variables to assess whether a survival advantage exists for female compared with male SCCHN patients receiving similar care. EXPERIMENTAL DESIGN We selected 286 female patients and 286 matched male patients from within a prospective epidemiologic study on 1,654 patients with incident SCCHN evaluated and treated at a single large multidisciplinary cancer center. Matching variables included age (±10 y), race/ethnicity, smoking status (never versus ever), tumor site (oral cavity versus oropharynx versus larynx versus hypopharynx), tumor classification (T(1-2) versus T(3-4)), nodal status (negative versus positive), and treatment (surgery, radiation therapy, surgery and radiation therapy, surgery and chemotherapy, chemoradiotherapy, or surgery and chemoradiotherapy). RESULTS Matched-pair and log-rank analyses showed no significant differences between women and men in recurrence-free, disease-specific, or overall survival. When the analysis was restricted to individual sites (oral cavity, oropharynx, or larynx/hypopharynx), there was also no evidence of a disparity in survival associated with sex. CONCLUSIONS We conclude that there is no evidence to suggest that a survival advantage exists for women as compared with men with SCCHN receiving similar multidisciplinary directed care at a tertiary cancer center.

Abstract
It is unknown whether population-level racial or ethnic disparities in mortality from squamous cell carcinoma of the head and neck (SCCHN) also occur in the setting of standardized multidisciplinary-team directed care. Therefore, we conducted a matched-pair study that controlled for several potentially confounding prognostic variables to assess whether a difference in survival exists for African American or Hispanic American compared with non-Hispanic white American SCCHN patients receiving similar care. Matched pairs were 81 African American case and 81 non-Hispanic white control patients and 100 Hispanic American cases and 100 matched non-Hispanic white controls selected from 1,833 patients of a prospective epidemiologic study of incident SCCHN within a single, large multidisciplinary cancer center. Matching variables included age (+/-10 years), sex, smoking status (never versus ever), site, tumor stage (T(1-2) versus T(3-4)), nodal status (negative versus positive), and treatment. Cases and controls were not significantly different in proportions of comorbidity score, alcohol use, subsite distribution, overall stage, or tumor grade. Matched-pair and log-rank analyses showed no significant differences between cases and controls in recurrence-free, disease-specific, or overall survival. Site-specific analyses suggested that more aggressive oropharyngeal cancers occurred more frequently in minority than in non-Hispanic white patients. We conclude that minority and non-Hispanic white SCCHN patients receiving similar multidisciplinary-team directed care at a tertiary cancer center have similar survival results overall. These results encourage reducing health disparities in SCCHN through public-health efforts to improve access to multidisciplinary oncologic care (and to preventive measures) and through individual clinician efforts to make the best multidisciplinary cancer treatment choices available for their minority patients. The subgroup finding suggests a biologically based racial/ethnic disparity among oropharyngeal patients and that prevention and treatment strategies should be tailored to different populations of these patients.

Abstract
The recent changes in incidence and prevalence of oral squamous cell carcinoma in relation to gender and age mirror the changing patterns of exposure to tobacco and alcohol, the main etiological agents. Most cases of oral cancer are managed by surgery, often combined with radiotherapy. Histopathological assessment of the resection specimen provides information vital for postoperative management and prognosis. This review considers the full range of histological determinants of outcome in relation to the primary oral tumor and any metastatic involvement of the cervical lymphatic system, together with an outline of more general patient factors that may also impact on morbidity and mortality rates.

Abstract
OBJECTIVES The purpose of this study was to evaluate the independent role of gender in affecting prognosis in patients with anterior tongue cancer. DESIGN Patients recorded in the head and neck cancer registry of Milano-Bicocca School of Medicine between January 1981 and December 1998 were reviewed. Female patients with squamous cell carcinoma of the tongue were identified and matched to men for year of diagnosis, age, TNM classification, histologic grading, and treatment modalities. For each woman, two men were matched. RESULTS Seventy-one women and 142 men satisfied our selection criteria. The frequency of recurrences was similar in the two study groups. This event occurred in 33 (46%) women and in 78 (55%) men (Fisher exact test, P = 0.25). The survival analysis confirmed that the rate of recurrences did not differ (log-rank test, P = 0.31). The number of cancer-related deaths in women and men was 23 (32%) and 55 (39%), respectively (Fisher exact test, P = 0.45). The survival analysis confirmed that gender did not affect survival (log-rank test, P = 0.34). CONCLUSION In this study, gender does not influence prognosis in patients with oral tongue cancer.

Abstract
OBJECTIVE The purpose of this study was to examine the oropharyngeal cancer pattern among different ethnic groups in Taiwan. METHODS The sample population was divided into three ethnic groups: the Fukkien, Hakka, and aboriginal communities. Age-standardized mortality rates (SMRs) and age-standardized incidence rates (SIRs) were estimated among these ethnic groups for the period 1979-1996/1997. RESULTS Our study found that the higher oropharyngeal cancer mortality and incidence rates in females of aboriginal groups are statistically significant, and higher than reference groups for both genders (SMR=3.76, SIR=2.18). However, in the lower areca quid chewing aboriginal groups, the higher pattern was not seen in females, and the lower pattern was even found in males. The incidence and mortality rate of oropharyngeal cancer in Hakkas was significantly lower than in the reference group. CONCLUSIONS The pattern of oropharyngeal cancer in Taiwan showed ethnic differences. The differences may be due to variation in exposure to different risk factors; however, in our study, we found that genetic differences might also be considered when explaining the different oropharyngeal cancer patterns among ethnic groups.

Abstract
Background In Taiwan, a distinct ethnic group variation in incidence and mortality rates has been suggested for most carcinomas. Our aim is to identify the role of prognostic factors associated with the survival of oral and pharyngeal carcinoma in Taiwan. Methods Taiwan Cancer Registry records of 9039 subjects diagnosed with oral and pharyngeal carcinoma were analyzed. The population was divided into three ethnic groups by residence, which were Taiwanese aborigines, Hakka and Hokkien communities. Five-year survival rates were estimated by Kaplan-Meier methods. Ethnic curves differed significantly by log-rank test; therefore separate models for Taiwanese aborigines, Hakka and Hokkien were carried out. The Cox multivariate proportional hazards model was used to examine the role of prognostic factors on ethnic survival. Results The five-year survival rates of oral and pharyngeal carcinoma were significantly poorer for Hokkien community (53.9%) and Taiwanese aborigines community (58.1%) compared with Hakka community (60.5%). The adjusted hazard ratio of Taiwanese aborigines versus Hakka was 1.07 (95%CI, 0.86–1.33) for oral and pharyngeal carcinoma mortality, and 1.16 (95%CI, 1.01–1.33) for Hokkien versus Hakka. Males had significantly poor prognosis than females. Subjects with tongue and/or mouth carcinoma presented the worst prognosis, whereas lip carcinoma had the best prognosis. Subjects with verrucous carcinoma had better survival than squamous cell carcinoma. Prognosis was the worst in elderly subjects, and subjects who underwent surgery had the highest survival rate. Conclusion Our study presented that predictive variables in oral and pharyngeal carcinoma survival have been: ethnic groups, period of diagnosis, gender, diagnostic age, anatomic site, morphologic type, and therapy.

Abstract
The aim of this study was to determine the risk factors for the mortality during the first 30 days after a major head and neck cancer surgery. Two hundred and sixty one consecutive surgical procedure were prospectively studied at Oscar Lambret Cancer Centre within a 36-months period. Twenty variables were recorded for each patient. The significant risk factors for postoperative mortality were assessed by univariate and multivariate analysis. Overall 30-days mortality rate was 3.83% [95% CI 3.13-4.53]. In univariate analysis identified four risk factors: female gender (odd ratio 4.25 [95% CI 1.03-17.56]), age equal or superior than 70 (odd ratio 5.06 [95% CI 1.35-18.36]), current alcohol addiction (odd ratio 3.65 [1.02-13.06]) and laryngeal location (odd ratio 4.23 [CI 95% 1.18-3.38]). In multivariate analysis only female gender and laryngeal location remained significant. The incidence of postoperative mortality was 1.63% for patients without risk factor and was 6.41% for those with one or two risk factors. This model identifies easily high-risk patients for major head and neck cancer surgery. A multicenter validation is necessary.

Abstract
Histopathological assessment of the surgical resection specimen continues to provide information that is central to determining the post-operative treatment needs and prognosis for an individual patient with oral/oropharyngeal squamous cell carcinoma. This review describes the prognostic value of histopathological features related to the primary tumour and the cervical lymph nodes, and considers their relative merits. In addition, a brief overview of more general patient factors is included. Throughout the review, guidance is offered on practical aspects of the histopathological assessment together with brief mention of potential inaccuracies. Emphasis is given also to the importance of the partnership between the surgeon and the pathologist, the need for standardisation during all stages of the histopathological assessment, and the value of accurate documentation of the findings.

Abstract
The incidence of occult neck metastasis in early stage tumours of the tongue and floor of the mouth varies from 20% to 30%, and the survival rates in 5 years from 73% to 97%. This study analyzes the rates of occult metastasis and prognostic factors for clinical stages I and II squamous cell carcinoma of the tongue and floor of the mouth. The records of patients with squamous cell carcinoma of the tongue and floor of the mouth, without prior treatment and treated by surgery between 1965 and 1998 were reviewed. All cases were re-staged and the surgical specimens were reviewed. This study included 193 patients, 145 men (75.1%), with ages ranging from 29 to 89 years old (mean, 60 years). The tumour site was the tongue in 132 cases (68.4%), the floor of the mouth in 45 (23.3%) and both in 16 (8.3%). With regard to stage, 85 cases were at clinical stage I (44.0%) and 108, clinical stage II (56.0%). One hundred and seventeen patients (60.6%) were submitted to a neck dissection and 27 (23.1%) had metastasic lymph nodes (pN+). The only factor associated with the presence of occult metastasis for all patients was the presence of muscular infiltration (p = 0.020); for tongue tumours the presence of vascular embolization (p = 0.043) and the presence of desmoplastic reaction (p = 0.050); for floor of the mouth tumours and T2 tumors, the histological grade (p = 0.025 and p = 0.035, respectively). Disease-free survival in 5 years was 66.4% and overall survival in 5 years 68.5%. The only factor associated with disease-free survival was the presence of muscular infiltration (p = 0.019) and with overall survival were gender (p = 0.002) and clinical stage (p = 0.031). Tumours of the tongue and floor of the mouth in the initial stages, which had muscular infiltration showed a higher probability of occult metastasis and lower disease-free survival; T2 tumours showed a worse survival as did patients of the male gender.

Abstract
In Taiwan, a clear gender difference emerges for rates of oropharyngeal carcinoma incidence. The purpose of this study was to identify the gender differences and clinical factors associated with oropharyngeal carcinoma survival rates in Taiwan. We analyzed the 5-year survival rates of 8114 subjects diagnosed with oropharyngeal carcinoma between 1987 and 1994. The Cox proportional-hazards model identified clinical characteristics for gender according to oropharyngeal carcinoma death and all-cause death outcomes. The 5-year survival rates were significantly lower for males than females (p < 0.0001). The adjusted hazard ratio of males versus females was 1.54 (95% CI: 1.36-1.74) for oropharyngeal carcinoma death and 1.44 (95% CI: 1.31-1.58) for all-cause death. Gender and other clinical characteristics (i.e. diagnostic age, anatomic site, morphologic type, and treatment modality) play important roles in oropharyngeal carcinoma survival. We suggested that Taiwanese males have high proportion of betel quid chewing and that this is associated with the gender differences.

Abstract
OBJECTIVE: Despite the substantial rate of neck conversion reported among patients with early oral cancer, a policy of routine elective neck dissection has been criticized on the grounds that it confers little survival advantage while subjecting many to potentially avoidable morbidity. However, the identification of factors predictive of survival may allow for the identification of those patients who are more likely to benefit from elective neck treatment.
STUDY DESIGN AND SETTING: The clinical and histologic material of 71 patients with stage I or II squamous carcinoma of the oral cavity were reviewed. Patients were followed up for a minimum of 3 years after their surgery, and the impact of these variables on 3-year survival was assessed.
RESULTS: Increased tumor thickness was significantly predictive of decreased survival ( P = 0.030). Although having no prognostic value alone, when combined with thickness, both pattern of invasion and gender increased the significance of the latter in predicting outcome.
CONCLUSION AND SIGNIFICANCE: Measuring tumor thickness and pattern of invasion in patients with early oral cancer may allow for the identification of those patients with more aggressive disease who are more likely to benefit from elective neck treatment.

Abstract
Although studies have established human papillomaviruses (HPVs) as a risk factor for oral and oropharyngeal cancer, it is not clear whether viral infection affects survival in head and neck malignancies. This investigation examined the relationship between HPV and survival in carcinomas of the oral cavity and oropharynx. Formalin-fixed, paraffin-embedded tumor specimens from 139 newly diagnosed cases were tested for HPVs by PCR and DNA sequencing. Patient and tumor characteristics were obtained from questionnaires, pathology reports and cancer registries. Odds ratios (ORs) and relative risks (RRs) were based on logistic and Cox regression models, respectively. HPVs were detected in 21% of the tumors; 83% were HPV-16. Greater risk of HPV infection was associated with males (OR = 2.9, 95% CI = 1.0-8.6), a history of oral-genital sex (OR = 4.2, 95% CI = 1.5-11.7), and oropharyngeal tumors (OR = 10.4, 95% CI = 3.5-31.2). As tobacco usage increased, the odds of HPV detection decreased (OR = 0.97/pack-year, 95% CI = 0.96-0.99). HPV infected patients had better overall survival (RR = 0.3, 95% CI = 0.1-0.8) than those with HPV-negative tumors. There was an interaction between gender and HPV for overall (p = 0.05) and disease-specific (p = 0.03) survival that suggested that HPV infected males had better prognosis than HPV-negative males, but this was not the case among females. HPV status was identified as an independent prognostic factor in oral and oropharyngeal cancers. This result appeared to be gender-specific, suggesting the need for further study of the interaction between HPV and gender on survival.

Abstract
A study was carried out on the occurrence of oral and pharynx cancer among populations living in five Brazilian geographic regions, by using incidence and mortality rates and trends. Information on survival was also analyzed. Complementary information regarding prevalence of the disease risk factors has been supplied in the attempt to establish some etiological connections with the incidence and mortality observed. Two clear patterns for the occurrence of oral and pharyngeal cancer have been detected: a pattern for the north (including the northern, northeastern and midwestern regions, which are the poorest ones) and a pattern for the south (including the southern and southeastern regions). The southern pattern revealed incidence rates higher than 15 per 100,000 among males, and the northern pattern displayed lower rate levels. Similarly, mortality rates in the south were higher than three per 100,000 and the northern pattern was characterized by lower rates. Other cancers linked to tobacco smoking, such as esophagus, larynx, lung and bladder cancer kept the same pattern of incidence and mortality rates related to oral and pharyngeal cancer in males per region. Information on survival of patients with oral and pharyngeal cancer was very restricted in Brazil, thus hindering the survival analysis per region, but the studies conducted allowed to conclude that the majority of diagnoses were conducted in advanced stages of the disease and implied the low 5-year survival rate observed in Brazil. Tongue tumors displayed the worst survival rates. The southern region shares specific risk factors involved in the oral and pharyngeal cancer present in the Argentinean and Uruguayan populations, namely heavy tobacco smoking and alcohol consumption, as well as high intake of charcoal-grilled red meat and mate. In addition to these risks, part of the oral and pharyngeal cancer registered in Brazil might be linked to a few factors present among people with low life standards, including poor oral hygiene and nutrition.

Abstract
BACKGROUND Oral cancer has been identified as a significant public health threat. Systematic evaluation of the impact of this disease on the US population is of great importance to health care providers and policy makers. METHODS This study used the National Cancer Data Base (NCDB) to evaluate associations between demographic and disease characteristics, treatment, and survival for patients with oral cavity cancer in the United States. Of patients diagnosed between 1985 and 1996, 58,976 were extracted from the NCDB. ANOVAs were performed on selected cross-tabulations, and relative survival was used to calculate outcome. RESULTS Median age of patients was 64.0 years. Men made up 60.2% of patients. Pathologic diagnosis was squamous cell carcinoma (SCC) in 86.3% of cases. Younger patients had a much higher frequency of non-SCC, and this was related to survival in these patients. African-Americans (independent of income), lower income patients, and patients with higher grade disease were seen more frequently with advanced-stage SCC. Five-year relative survival for SCC cases was lower for older patients, men, and African-Americans. CONCLUSIONS This study addressed many issues related to oral cancer that have been previously discussed in the literature. The demographic, site, stage, histologic, and survival data available for this large number of cases in the NCDB allowed an accurate characterization of the contemporary status of oral cancer in the United States.

Abstract
BACKGROUND This study was designed to determine if race and age are independent prognostic factors for survival in patients treated for squamous cell carcinoma of the oral cavity and pharynx. METHODS Retrospective study. RESULTS Out of 909 patients registered, 815 (90%) were white and 94 (10%) were African-American. The median age was 60 years (range 19-93). The African-American patients had a significantly lower 5 year survival rate of 27.6% (95% CI 19.9-38.3) compared with white patients with a survival rate of 52.0% (95% CI 48.7-55.6) (P < 0.001). The greatest racial disparities in survival were observed in patients under 60 years of age [29.2% (95% CI 19.5-43.6) vs 60.9% (95% CI 56.3-66.0) for African-American and white patients, respectively, P < 0.001], and in African-American men compared with white men [20.2% (95% CI 12.6-30.2) vs 51.0% (95% CI 46.7-53.0), P < 0.001]. A multivariate Cox model, stratified according to stage of disease, indicated that race, age, and type of treatment were statistically significant predictors of survival. After adjusting for race and treatment received, African-American patients had a relative risk of dying of 1.61 (95% CI 1.23-2.10) compared with white patients. All patients 60 years of age and older had a higher risk of dying 1.59 (95% CI 1.31-1.92). Compared with surgical treatment alone, radiotherapy and other treatments were both associated with increased risk of dying with respective relative risks of 1.34 (95% CI 1.01-1.76) and 1.94 (95% CI 1.52-1.48). CONCLUSIONS African-American patients had poorer survival outcomes, with race and age emerging as significant independent predictors of survival after treatment for oral and pharyngeal cancer, compared with their white counterparts. Primary and secondary prevention programs that target younger patients at high risk might reduce environmental risk factors such as smoking and alcohol consumption, which may play a greater role in the acquired susceptibility for oral and pharyngeal cancer in African-American males.

Abstract
The delayed time period between the first diagnosis of a head and neck cancer and its treatment can affect not only the clinical staging of the disease, but also its prognosis. The time period for clinical upstaging is studied in a retrospective cohort series. A retrospective case/control series was established to assess the prognosis of head and neck cancer patients due to a delay in treatment. In the first part of the study we included 69 patients who had confirmed clinical upstage before starting the oncologic treatment (cases). The survival of this series was compared to a historical control group of 138 patients matched by tumour site and stage, having received treatment within a short period after their first medical evaluation (controls). We observed that the natural evolution of a head and neck cancer was progressively faster, from an initial clinical stage to an advanced clinical stage until it becomes untreatable. It was observed that the delay in beginning oncologic treatment influenced the prognosis of the patients (P=0.030), especially in clinical stage IV patients (P=0.001) and oral cavity cancer patients (P=0.007).

Abstract
Oral squamous-cell carcinoma, the main type of oral cancer, is among the ten most common cancers in the world. The aims of this paper were first, to consider whether there was evidence of marked ethnic variations in the incidence, management, and survival of oral cancer, and then, to review possible explanations for these variations. Evidence from the literature suggests that there is marked, inter-country variation in both the incidence and mortality from oral cancer. There is also growing evidence of intracountry ethnic differences, mostly reported in the UK and USA. These variations among ethnic groups have been attributed mainly to specific risk factors, such as alcohol and tobacco (smoking and smokeless), but dietary factors and the existence of genetic predispositions may also play a part. Variations in access to care services are also an apparent factor. The extent of ethnic differences in oral cancer is masked by the scarcity of information available. Where such data are accessible, there are clear disparities in both incidence and mortality of oral cancer between ethnic groups.

Abstract
Squamous cell carcinoma of the upper respiratory and digestive tract has a high risk for neck metastasis, which reduces the probability of regional control and survival. We analyzed the literature and our own experience to review the possible risk factors for the occurrence of metastasis. The most significant risk factors were: tumor site and size, grade of histologic differentiation, tumor thickness (tongue and floor of mouth carcinoma), vascular embolization, and perineural infiltration. A series of biomarkers has been studied over the last 10 years, but no one has proved to be significant enough for clinical use. Based on several multivariate analysis, it is recommended elective treatment of the neck for high-risk patients.

Abstract
Despite the belief that cancer mortality can be reduced if lesions are detected, diagnosed and treated at an early stage, only one study, among a number concerning cancers of the upper aerodigestive tract (UADT), has found any relationship between such delays and prognosis for this population of cancer patients. The aim of this study was, therefore, to investigate the relationship between patient and professional diagnostic delays and patient prognosis in a group of UADT cancer patients. Patients diagnosed with squamous cell carcinoma of oral cavity sites (ICD-9 141, 143-5)oro-, naso- and hypopharynx (ICD-9 146-8) and larynx (ICD-9 161) were included in the study. Stepwise multiple logistic regression was used to calculate the odds ratio (OR) of late versus early stage disease for selected study variables. The sample comprised 188 subjects. Multivariate analysis found that having a pharyngeal cancer (OR 9.26; 95% CI 4.02-21.32; P: 0.0001) a professional delay > 1 month (OR 2.28; 95% CI 1.13-4.64; P: 0.022) and age > or = 65 years (OR: 0.45; 95% CI: 0.22-0.91; P: 0.024) were predictive of late stage disease. A dose-response relationship between professional delay and OR for late stage disease for the whole sample (P for trend 0.03) and among those with oral cancer (P for trend 0.0001) was found. The results of this study suggest that, among patients with an UADT cancer, professional delays > 1 month are contributing to an increased risk for being diagnosed with late stage disease.

Abstract
OBJECTIVE This study seeks to determine whether lower survival of black versus white oral and pharyngeal cancer patients is due to, or differs by, stage at diagnosis. METHODS Subjects identified through the North Carolina Central Cancer Registry included all black and white North Carolina residents diagnosed from 1987 to 1990 with malignant squamous cell carcinoma of the oral cavity or pharynx. Proportional hazards regression models were used to calculate hazard ratios for all-cause mortality during the first 18 months after diagnosis, adjusting for age, reported histologic grade, site, and several time-dependent interactions. RESULTS Within the first two months after diagnosis, the black/white hazard ratio for mortality among those with localized disease was 11.8 (95% CI = 3.7, 37.5), compared to 6.4 (95% CI = 2.6, 15.8) for those with advanced disease. During months 3 to 18 after diagnosis, black/white hazard ratios were 2.07 (95% CI = 1.03, 4.18) among those with localized disease and 1.12 (95% CI = 0.85, 1.47) for those with advanced disease. CONCLUSIONS In the first 18 months after diagnosis, blacks with oral and pharyngeal cancer have higher all-cause mortality than whites diagnosed at the same stage of disease. Racial differences are greater among those with localized disease than for those with more advanced conditions.

Abstract
Fifty-three patients with T1 squamous cell cancer of the floor of mouth and ventral surface of the tongue with a known clinical outcome were retrospectively analyzed and arbitrarily divided into "aggressive" and "nonaggressive" groups based on their clinical behavior. Various host and tumor factors were then evaluated in an attempt to determine whether the tumor behavior could have been predicted. The paraffin-embedded tumor specimens were evaluated for tumor differentiation, tumor thickness and tumor invasion, microvessel density, and p53 expression. In addition, a composite morphologic grading score was obtained by combining cell differentiation, nuclear polymorphism, mitosis activity, depth of infiltration, type of infiltration, and lymphatic infiltration. No single technique appeared capable of identifying "aggressive" behavior, although possibly an evaluation of composite factors might show promise in the future.
