Abstract
Globally, HIV/AIDS and cancer are increasingly public health problems and continue to exist as comorbidities. The sub-Saharan African region has the largest number of HIV infections. Malignancies previously associated with HIV/AIDS, also known as the AIDS-defining cancers (ADCs) have been documented to decrease, while the non-AIDS defining cancer (NADCs) are on the rise. On the other hand, cancer is a highly heterogeneous disease and precision oncology as the most effective cancer therapy is gaining attraction. Among HIV-infected individuals, the increased risk for developing cancer is due to the immune system of the patient being suppressed, frequent coinfection with oncogenic viruses and an increase in risky behavior such as poor lifestyle. The core of personalised medicine for cancer depends on the discovery and the development of biomarkers. Biomarkers are specific and highly sensitive markers that reveal information that aid in leading to the diagnosis, prognosis and therapy of the disease. This review focuses mainly on the risk assessment, diagnostic, prognostic and therapeutic role of various cancer biomarkers in HIV-positive patients. A careful selection of sensitive and specific HIV-associated cancer biomarkers is required to identify patients at most risk of tumour development, thus improving the diagnosis and prognosis of the disease.

Abstract
To develop clinical nomograms for prediction of overall survival (OS) and cancer-specific survival (CSS) in patients with stage IV tongue squamous cell carcinoma (TSCC) after surgery based on the Surveillance, Epidemiology, and End Results (SEER) program database.We collected data of resected stage IV TSCC patients from the SEER database, and divided them into the training set and validation set by 7:3 randomly. Kaplan-Meier analysis and Cox regression analysis were adopted to distinguish independent risk factors for OS and CSS. Clinical nomograms were constructed to predict the 3-year and 5-year probabilities of OS and CSS for individual patients. Calibration curves and Harrell C-indices were used for internal and external validation.A total of 1550 patients with resected stage IV TSCC were identified. No statistical differences were detected between the training and validation sets. Age, race, marital status, tumor site, AJCC T/N/M status, and radiotherapy were recognized as independent prognostic factors associated with OS as well as CSS. Then nomograms were developed based on these variables. The calibration curves displayed a good agreement between the predicted and actual values of 3-year and 5-year probabilities for OS and CSS. The C-indices predicting OS were corrected as 0.705 in the training set, and 0.664 in the validation set. As for CSS, corrected C-indices were 0.708 in the training set and 0.663 in the validation set.The established nomograms in this study exhibited good accuracy and effectiveness to predict 3-year and 5-year probabilities of OS and CSS in resected stage IV TSCC patients. They are useful tools to evaluate survival outcomes and helped choose appropriate treatment strategies.

Oral Oncol 2014; 50:1081-8. [PMID: 25156479 DOI: 10.1016/j.oraloncology.2014.08.003] [Citation(s) in RCA: 25] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/26/2014] [Revised: 07/25/2014] [Accepted: 08/07/2014] [Indexed: 11/27/2022]
Abstract
BACKGROUND The aim of this study was to describe risk factors of contralateral neck recurrence (CLNR) and to identify its high-risk population after treatment for unilateral oral squamous cell carcinoma. METHODS Between June 1991 and June 2012, a total of 1482 eligible patients who were treated with radical surgery with or without adjuvant therapy were retrospectively reviewed. RESULTS The outcome assessment parameters were the rate of 5-year CLNR and the rate of disease-specific survival (DSS). In the entire study cohort, the 5-year CLNR rate was 4.1%. In a multivariate analysis, only extracapsular spread (ECS) status (hazard ratio [HR]: 12.978, 95% confidence interval [CI]: 1.328-126.829, P=0.028) was an independent risk factor for 5-year CLNR. In addition, 5-year CLNR (HR: 36.410, 95% CI: 7.093-186.914, P<0.001), T stage (HR: 3.475, 95% CI: 1.151-10.488, P=0.027) and growth pattern (HR: 4.831, 95% CI: 1.776-13.140, P=0.002) were independent risk factors for 5-year DSS. Patients with at least two risk factors were identified as a high-risk population for CLNR; these patients also had a poor prognosis. Elective contralateral neck dissection (ND) plus concurrent chemoradiotherapy (CCRT) can improve the 5-year DSS in these high-risk patients, but it does not decrease the 5-year CLNR rate. CONCLUSION For low- and moderate-risk patients, contralateral neck observation should be considered sufficient if strict compliance with a cancer surveillance protocol is followed. However, whether high-risk patients benefit from contralateral ND plus adjuvant CCRT can only be answered in a prospective trial.

Abstract
Brachytherapy using (198)Au grains is minimally invasive and the only curative treatment for early tongue cancer in patients of advanced age or poor performance status available in our institution. From March 1993 to February 2008, (198)Au grains were used to treat a group of 96 Stage I-II tongue cancer patients who could not undergo surgery or brachytherapy using (192)Ir pins because of an advanced age (≥75 years) or poor performance status (≥2). The patients were followed for 3.9 ± 3.3 years, and the cause-specific survival and local control rates were determined. Survival analyses were performed using the Kaplan-Meier method, and univariate and multivariate analyses were performed using the Cox proportional hazard model. The results were compared with those for a group of 193 early tongue-cancer patients who underwent treatment using iridium pins. The 5-year cause-specific survival and local control rates of the (198)Au grains group were 71% and 68%, respectively, both of which were 16% lower than the corresponding rates for the (192)Ir pins group. Our study demonstrated that as the last curative treatment available, (198)Au grain implantation could be used to achieve moderate treatment results for early tongue cancer in patients of advanced age or poor performance status.

Abstract
Brachytherapy delivers a high radiation dose to a limited volume while sparing surrounding normal tissues. In head and neck cancer, severe soft-tissue damage and bone damage to the mandible has decreased markedly since the introduction of computer dosimetry and the use of spacers during treatment. For the curative treatment of head and neck cancer, the selection of brachytherapy sources from among the several linear and small permanent implant sources available, not only according to the tumor site but also according to the patient's physical and mental condition is important. Following the successful treatment of early head and neck cancer by brachytherapy, two major problems and one minor problem may confront the physician. The major problems are neck node metastasis and a second primary cancer of the respiratory tract or upper digestive tract, and the minor problem is radiation-induced cancer.

Contralateral lymph neck node metastasis of squamous cell carcinoma of the oral cavity: a retrospective analytic study in 315 patients. J Oral Maxillofac Surg 2008; 66:1390-8. [PMID: 18571022 DOI: 10.1016/j.joms.2008.01.012] [Citation(s) in RCA: 38] [Impact Index Per Article: 2.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/06/2007] [Revised: 10/16/2007] [Accepted: 01/01/2008] [Indexed: 11/24/2022]
Abstract
PURPOSE In relation to primary squamous cell carcinoma (SCC) of the oral cavity, many clinical and histopathologic factors have been reported to be predictive for lymph neck node relapse. However, few large studies concerning the association between clinical-histopathologic features and the development of contralateral lymph neck node relapse (CLNR) after surgical resection of primary SCC of the oral cavity are available. The purpose of this study was to analyze those factors related to the appearance of contralateral lymph neck node relapse in patients with SCC of the oral cavity primarily treated by means of surgery. PATIENTS AND METHODS This study was based on a series of 315 consecutive patients with primary SCC of the oral cavity treated between June 1979 and December 1999. All patients were treated primarily by means of surgery with or without adjuvant radiotherapy. The following data were analyzed for each patient: age, gender, habits, time to diagnosis, performance status, tumor clinical features, histologic grade, TNM staging, type of neck dissection, survival outcome, and functional/esthetic results at the end of the follow-up period. Histologic study included the pTNM classification, tumor size, surgical margins, extracapsular spread of lymph neck node metastasis, perineural infiltration, peritumoral inflammation, and bone involvement. RESULTS Eighty-three patients eventually died of the disease (26.34%). A total of 177 patients were alive with no evidence of recurrence at the end of the study. The mean disease-specific survival rate was 147 +/- 6 months. Twenty-nine (9.1%) patients developed ipsilateral lymph neck node relapse (ILNR), whereas 18 (5.69%) patients developed CLNR. The mean period of time from surgery to the appearance of CLNR was 12.52 months (range, 3 to 49 months). Eighteen of 29 patients with ILNR finally died of the disease. Seven of 18 patients with CLNR died of the disease. Several clinical-pathologic features were predictive for CLNR in SCC of the oral cavity, such as the time to diagnosis, TNM staging, positive ipsilateral clinical N status, histopathologic differentiation, surgical margins of primary tumor resection, type of neck dissection, and perineural infiltration. CONCLUSION Delay in diagnosis 12 or more months is associated with increased CLNR. Clinical and pathologic factors predictive for CLNR are TNM tumor staging IV, histopathologic poor-differentiation of the primary tumor, surgical margins less than 1 cm around the primary tumor, performance of isolated ipsilateral modified type III radical neck dissection, and perineural tumor involvement. Presence of ipsilateral neck metastasis at the time of diagnosis is associated with an augmented incidence of CLNR in SCC of the oral cavity.

Abstract
Detecting the risk factors for late neck metastasis (LNM) in early tongue and oral floor cancer is important for establishing an accurate prognosis, as well as for increasing survival rates. Patients with either stage I or II tongue and oral floor cancer underwent either a resection of the primary tumor or interstitial radiotherapy without neck dissection. We measured the short- and long-axis diameters of lymph nodes on initial CT images. Of the 38 patients, 20 had LNM and 18 did not. CT images showed a total of 161 lymph nodes. Twenty-five "occult lymph nodes" developed into LNM, whereas the remaining 136 "reactive lymph nodes" did not. Comparison between "occult" and "reactive" lymph nodes revealed significant differences in the short-axis diameters (p=0.01). The measure of short-axis diameters of neck lymph nodes on initial CT images is a useful predictor of LNM in patients with early tongue and oral floor cancer.

Abstract
In primary squamous cell carcinoma (SCC) of the oral cavity, many clinical and histopathological factors have been described as predictive for cervical lymph-node metastasis, but there are no data available on this association for surgical resection of lateral tongue primary SCC. The aim of this study was to analyse factors related to contralateral neck relapse in a series of 203 consecutive patients with SCC of the lateral aspect of the tongue treated by surgery with or without adjuvant radiotherapy. Several clinical features were analyzed. Histological study included pTNM classification, tumour size, surgical margins, extracapsular spread of lymph-node metastasis, perineural infiltration, peritumoral inflammation and bone involvement. The mean duration of follow up for surviving patients was 70.9+/-49.6 months; 47 patients eventually died of the disease and 116 patients are alive with no evidence of recurrence. The mean disease-specific survival time was 149+/-7 months. Twenty (9.8%) patients developed ipsilateral and nine (4.4%) contralateral neck recurrence. The mean period of time from surgery to contralateral neck recurrence was 11.4 months (range 3-27 months). Fourteen of the 20 ipsilateral and 8 of the 9 contralateral neck relapse patients eventually died of the disease. Histopathological grading and peritumoral inflammation were found to be statistically significant (P<0.05). Clinical and pathological lymph neck node status was not found to be associated with the appearance of contralateral lymph neck node relapse. Due to the increased risk of contralateral neck relapse within the first 2 years of surgery, close surveillance is mandatory at this time.

Abstract
Background There is no consensus as to the prognostic model for brachytherapy of tongue carcinoma. This study was designed to evaluate the prognostic factors for local control based on a large population under a unified treatment policy. Results Between 1970 and 1998, 433 patients with stage II tongue squamous cell carcinoma were treated by low-dose-rate brachytherapy. This series included 277 patients treated with a linear source with a minimum follow-up of 3 years. A spacer was introduced in 1987. The primary local control rates were 85.6%. Conclusion In the multivariate analysis, an invasive growth pattern was a significant factor for local recurrence. The disease-related survival was influenced by old age and an invasive growth pattern. A spacer lowered mandibular bone complications. The growth pattern was the most important factor for recurrence. Brachytherapy was associated with a high cure rate and the use of spacers brought about good quality of life (QOL).

Abstract
BACKGROUND Although many histopathological characteristics of oral squamous cell carcinoma (O-SCC) have been identified as prognostic factors, no factor is completely accurate and unequivocal. This study evaluated the association between the loss of syndecan-1 expression and the histological grade of malignancy at the deep invasive front in O-SCC. METHODS The expression of syndecan-1 at the invasive tumor front of O-SCC was examined immunohistochemically using archived tissue from 72 cases. The mean age of the patients was 62.5 years (range: 23-90 years) and the male-female ratio was 1.3:1 (41 men, 31 women). There were 26, 24, 11, and 11 cases classified as stages I-IV respectively. The correlation between the intensity of syndecan-1 immunostaining and the clinicopathological factors, especially the histological grade of malignancy at the deep invasive front (invasive front grade) was analyzed. RESULTS Of the 72 cases, seven (9.7%), 29 (40.3%), 36 (50.0%) showed strong, intermediate, and weak or negative syndecan-1 staining respectively. There were significant differences between syndecan-1 expression and prognosis, differentiation, and pattern of invasion at the deep invasive front. Moreover, the invasive front grade scores, based on the intensity of syndecan-1 staining, were 5.6 +/- 1.0, 8.0 +/- 2.1, and 10.2 +/- 2.3 points with strong, intermediate, and weak or negative intensity respectively; and the difference was significant (P < 0.0001). Patients with intermediate or strong intensity for syndecan-1 had significantly better prognoses than did those with negative or weak intensity (P = 0.0138). CONCLUSION This study demonstrated that the reduced expression of syndecan-1 seems to be a useful marker of histological malignancy at the deep tumor invasive front and may be a useful prognostic factor in O-SCC.

Abstract
The purpose of this study is to describe the cause-specific survival rate, local control rate, salvage rate of neck metastasis, and post-treatment eating and speaking conditions for stage III mobile tongue squamous cell carcinomas and its subgroups. Between 1968 and 1999, 117 previously untreated patients with stage III mobile tongue carcinomas underwent mainly brachytherapy with external beam irradiation (EBRT) and neck dissection. A multivariate analysis was performed for the cause-specific survival rate on the various factors. The 1-, 3- and 5-year cause-specific survival rates for all patients were 76%, 54% and 54%, respectively. The 1-, 3- and 5-year primary control rates for all patients were 67.6%, 63.4% and 59.2%, respectively. There were statistically significant differences in cause-specific survival rates among stage III subgroups of T3N0, T1-2N1 and T3N1 (p = 0.0002). Our treatment method for patients with stage III mobile tongue squamous cell carcinoma was effective and acceptable.

Abstract
BACKGROUND Although many histopathologic characteristics of oral squamous cell carcinoma (O-SCC) have been identified as prognostic factors, accurate, and unequivocal factors have not been clearly identified. The purpose of this study was to evaluate a potential association between the histologic grade of malignancy at the deep invasive front and the expression of Ki-67 antigen and p53 protein in O-SCC. METHODS The expression of Ki-67 antigen and p53 at the invasive tumor front area of O-SCC was examined by immunohistochemistry of archived tissue from 62 cases. The mean age of patients was 60.7 years (range: 37-89) and the male-female ratio was 1.6:1 (38 men, 24 women). There were 20, 17, 14, and 11 cases classified as stage I to stage IV, respectively. The correlation between the intensity of immunostaining for Ki-67 antigen and p53 and the histologic grade of malignancy at the deep invasive front (invasive front grade, IFG) was analyzed. The expression of Ki-67 antigen and p53 in normal oral epithelia (10 cases) was also investigated. RESULTS The mean Ki-67 labeling index (LI) in the O-SCC samples was 32.8 +/- 12.0% (n = 62). The mean total score of IFG (IFG score) was 9.1 +/- 2.7 points (n = 62). There was a significant linear correlation between the IFG score and the Ki-67 antigen (gamma = 0.651, R2 = 0.596, P < 0.0001). Of 50 tumors examined, 27 (54.0%) exhibited p53-positive nuclear immunostaining. The staining patterns for Ki-67 antigen and p53 were similar. Both Ki-67-LI and p53-positive status were significantly correlated with the IFG scores. CONCLUSION The findings of this study demonstrate that overexpression of Ki-67 antigen and p53 at the deep tumor invasive front of O-SCC is associated with histologic grade of malignancy.

Abstract
BACKGROUND Although many histopathologic factors in squamous cell carcinoma of the tongue predict the prognosis, the major predictive factors have not been identified clearly. This study analyzed the prognostic value of the histologic grade at the deep invasive front of tongue squamous cell carcinoma. METHODS The clinicopathologic features of 124 consecutive patients seen between January 1985 and December 1999 with previously untreated squamous cell carcinoma of the tongue were reviewed. Their mean age was 58.5 years (range: 23-90) and the male-female ratio was 1.8: 1 (79 men and 45 women). There were 41, 40, 30, and 13 cases at stage I to stage IV, respectively. The clinicopathologic factors, especially the histologic grade at the deep invasive front (invasive front grade, IFG), were analyzed to determine factors predicting prognosis. RESULTS The 5-year disease-free survival rate of the patients treated with curative aim only was 66.7%. Clinicopathologic factors significantly associated with the prognosis were T classification, tumor size, stage classification, tumor depth, macroscopic appearance, cervical lymph node metastasis (nodal metastasis), microvascular invasion, and IFG. In a multivariate analysis, patients with tumor depth >/=4 mm, IFG >/=8 points, and nodal metastasis had a reduced disease-free survival and IFG >/=11 points had a predictive value for nodal metastasis (odds ratio: 7.34; P = 0.0019). CONCLUSION This study found that a high IFG malignancy score had a high prognostic value for squamous cell carcinoma of the tongue.

Abstract
OBJECTIVE Oral cancer is primarily a disease of epithelial origin. The tongue is the most common site of oral cancer. Oropharyngeal cancer accounts for approximately 2% of all cancer deaths. The purpose of this study was to analyze a case series of patients with tongue cancer. STUDY DESIGN The medical records of 322 consecutive patients diagnosed with squamous cell carcinoma (SCC) of the tongue treated from 1979-1994 were reviewed. RESULTS Patients had a mean age of 61.1 years and a 1.5:1 male to female ratio. Approximately, half of the cancers were diagnosed at an advanced stage and most involved the base of the tongue. The majority of oral tongue tumors were diagnosed at an early stage and had more well-differentiated cell types than those of the base of the tongue. Localized discomfort was the most common complaint (66.5%), present for up to 6 months in patients prior to diagnosis and were related to the oral tongue in 90% of cases. Symptoms associated with base of tongue lesions included neck masses, dysphagia, ear pain, and weight loss. Seventy-nine percent of the patients smoked, 58% consumed alcohol on a daily basis, and 43% consumed more than 4 alcoholic drinks daily. Primary radiotherapy was the treatment of 49.6% lesions, of which 57% were at an early stage at diagnosis. The mean overall survival was 3 years and 5 months, with a 5-year overall survival of 40%. Patients with stage 1 tumors had a disease-specific survival of over 80%. The 5-year survival of patients with cancer of the oral tongue was 43% and cancer of the base of the tongue was 27%. CONCLUSION The prognosis is poorer for patients presenting with advanced stage and with tumors involving the base of the tongue. Symptoms were more common in tumors of the oral tongue, which likely results in earlier diagnosis. Patients with SCC of the base of the tongue presented with advanced stage of disease and were typically poorly differentiated lesions.

Abstract
BACKGROUND Many histopathologic parameters in squamous cell carcinoma of the tongue have been identified as predictive factors for cervical lymph metastasis. However, predictive factors for occult cervical lymph node metastases and the criterion for elective therapy remain inconclusive. This study analyzed the clinicopathologic factors associated with late cervical lymph node metastases in patients with carcinoma of the tongue. METHODS The clinicopathologic features of 50 consecutive patients seen between January 1985-December 1996 with previously untreated stage I or II squamous cell carcinoma of the tongue were reviewed. All patients were treated with partial glossectomy without elective neck dissection. Their mean age was 54.5 y (range, 23-90 y) and the male-female ratio was 1.2:1 (27 men and 23 women); 30 cases were stage I, and 20 cases were stage II. Clinicopathologic factors were analyzed to determine factors predicting late cervical lymph node metastasis. RESULTS The overall cervical lymph node metastasis rate was 14.0% (7 of 50). Clinicopathologic factors significantly associated with the development of cervical lymph node metastasis were tumor size (> or =30 mm), tumor depth (> or =4 mm), differentiation, mode of invasion, microvascular invasion, and histologic grade of malignancy. In a multivariate logistic regression analysis, moderately differentiated squamous cell carcinoma of the tongue with tumor depth > or =4 mm had predictive value for late cervical lymph node metastasis and diminished overall survival (odds ratio, 10.0; p =.02; hazards ratio, 7.0; p =.039). CONCLUSIONS The findings of this study demonstrate tumor depth > or =4 mm moderately differentiated squamous cell carcinoma of the tongue have a substantially higher rate of late cervical metastases. In the basis of these data, it is our recommendation that this be used in the decision to electively treat the neck.

Abstract
OBJECTIVE The study reports the results of treatment of oral tongue cancer with five different treatment modalities with long-term follow-up. STUDY DESIGN Retrospective study of 332 patients with oral tongue cancer treated in the Departments of Otolaryngology-Head and Neck Surgery and Radiation Therapy at Washington University School of Medicine (St. Louis, MO) from 1957 to 1996. METHODS Patients with biopsy-proven squamous cell carcinoma of the oral tongue who were previously untreated and were treated with curative intent by one of five modalities and who were eligible for 5-year follow-up were included. The treatment modalities included local resection alone, composite resection alone (with neck dissection), radiation therapy alone, local resection with radiation therapy, and composite resection with radiation therapy. Multiple diagnostic, treatment, and follow-up parameters were studied using standard statistical analysis to determine statistical significance. RESULTS The overall 5-year disease-specific survival rate (DSS) was 57% with death due to tumor in 43%. The 5-year cumulative disease-specific survival probability (CDSS) was 0.61 (Kaplan-Meier) with a mean of 17.5 years and a median of 30.1 years. The DSS by treatment modality included local resection (73%), composite resection (61%), radiation therapy (46%), local resection and radiation therapy (65%), and composite resection with radiation therapy (CR/RT) (44%). Overall, local resection had a significantly improved DSS and CR/RT had a decreased DSS that was related to the stage of disease being treated. In treating stage IV disease, CR/RT produced a more significantly improved CDSS than the other treatment modalities. Recurrence at the primary site was as common as recurrence in the neck. Eighty-nine percent of recurrences occurred within the first 60 months. Recurrence significantly decreased survival. DSS was significantly improved in patients with clear margins of resection. Metastasis to a distant site occurred in 9.6% of patients. Twenty-one percent of patients had second primary cancers, and 54% of these patients died of their second primary cancer. CONCLUSIONS Significant improvement in DSS was seen in patients with clear margins, early stage grouping and clinical (pretreatment) tumor stage, and negative nodes. Significant decrease in DSS was seen in patients with close or involved margins, advanced stage grouping and clinical (pretreatment) tumor staging, positive clinical (pretreatment) node staging, and tumor recurrence. Obtaining clear margins of resection is crucial because it significantly affects survival. A minimum of 5 years of close monitoring is recommended because of the high incidence of second primary cancers.

Abstract
The aim of this study was to evaluate the usefulness of a contact neodymium YAG laser for the treatment of squamous cell carcinoma (SCC) of the mobile tongue in 35 patients. The TNM stage and histologic grade were as follows: T1, n = 20; T2, n = 11; T3, n = 4; and N0, n = 33; N1, n = 2; G1, n = 20; G2, n = 10; and G3, n = 5. The surgical treatment consisted of a hemiglossectomy or resection with adequate margins in 28 cases, and an ipsilateral neck dissection was also performed in 7 patients. Radiotherapy to a mean tumor dose of 62-64 Gy and an elective dose of 50 Gy to the cervical lymph nodes was given to 14 patients. The radiotherapy was preoperative in 12 patients and postoperative in 2. Tongue resection was easily performed using the contact neodymium YAG laser, with a mean operation time of 31 min and intraoperative bleeding varying from negligible to 100 cm3. During postoperative follow-up no major complications occurred: cases with minor hemorrhage were easily controlled on the ward and 1 patient had a bleed on the 14th postoperative day necessitating hospitalization. The resection was histologically radical in all cases. During follow-up one patient had a local recurrence (T2N0, G3) and four failed in the neck (T1N0 G2, T1N0 G2, T1N0 G2, T2N0 G2), three of whom were successfully salvaged with a neck dissection and radiotherapy. One patient with osteoradionecrosis was diagnosed and treated curatively. Two patients died of their tongue cancer (T2N0 G3, T2N0 G2), 1 died from a second primary tumor (T2N0 G1) and 2 of intercurrent disease with no evidence of cancer; 30 patients (86%) are still alive with no evidence of disease. The function of the tongue in all patients in this sample was good to satisfactory. The major complaint was xerostomia in the irradiated patients. In conclusion, the contact neodymium YAG laser appears to be suitable for resection of T1-T2 SCCs of the oral tongue. In this limited patient sample T stage or grade did not predict failures in the neck. Biologic predictive markers need to be evaluated.

Abstract
OBJECTIVE The purposes of the present study were to analyze our experience with preoperative chemoradiotherapy followed by surgery for advanced tongue carcinoma and to assess the prognostic value of response to preoperative therapy in these tumors. STUDY DESIGN Between May 1988 and December 1999, a total of 43 patients with advanced but potentially resectable squamous cell carcinoma of the tongue were candidates for this study. A minimum tumor size of 3 cm was required. The mean age was 59.8 years (range, 26-85 years); 13 cases were advanced stage II, 23 cases were stage III, and 7 cases were stage IV. All patients were treated preoperatively with cisplatin- or carboplatin-based chemotherapy in combination with simultaneous irradiation to a target volume of 40 Gy; 2-6 weeks later, they underwent curative surgery. Tumor regression rate, residual tumor grade, and histologic regression grade to the preoperative therapy were analyzed to determine their influence on the prognosis. RESULTS With a median follow-up of 60.5 months, overall survival rates were 86.0% for all cases, 92.3% for stage II cases, 77.3% for stage III cases, and 100% for stage IV cases. The progression-free survival rates according to tumor regression rate were 33.3% for group 1 (< 50% tumor regression), 66.7% for group 2 (> or = 50% and < 75% regression), 100% for group 3 (> or = 75% and < 100% regression), and 96.0% for group 4 (complete regression). The higher the tumor regression rates, the higher the survival rates. When patients who achieved a regression rate of 75% or higher were compared with those who did not, there was a significant difference in survival (P < .0001). The factors of residual tumor grade and histologic regression grade also had good correlations with the prognosis (residual tumor grade, P =.0324; histologic regression grade, P < .0001). CONCLUSIONS The findings of the present study suggest that response to preoperative chemoradiotherapy, such as tumor regression rate, residual tumor grade, and histologic regression grade, could be of prognostic value in patients with tongue carcinoma.

Abstract
The purpose of this study was to assess prognostic factors, treatment outcomes and patterns of relapse in patients with early stage (T1-2 N0) squamous cell carcinoma of oral tongue treated primarily by surgery. The medical records of all patients with early stage (T1-2 N0) oral tongue cancer, radically treated at King Faisal Specialist Hospital and Research Center between January 1980 and December 1997, were reviewed. Eighty-five patients were identified for analysis, 38 male and 47 female. With a median follow-up for surviving patients of 64 months, 5-year actuarial overall, disease-specific (DSS), and relapse-free survival (RFS) were 71, 75, and 63%, respectively. Univariate analysis for DSS showed survival advantage for patients with tumor thickness (TT) of < or =10 mm (P=0.0002) and distance from resection margin (DFRM) of > 5 mm (P=0.005). The effect of TT of < or =10 mm was maintained (P=0.001) on multivariate analysis. Higher RFS was observed with TT of < or =10 mm (P=0.0002), DFRM of > 5 mm (P=0.0002) and DFRM of >10 mm (P=0.007). On multivariate analysis higher RFS was also found for TT < or =10 mm (P=0.01) and DFRM >5 mm (P=0.01). Salvage of local tongue recurrence was higher than neck node failure, with 5-year DSS of 71 and 19%, respectively (P=0.007). Time interval for recurrence showed no significant impact on outcome. In T1-2 N0 oral tongue cancer, TT, and DFRM are significant prognostic factors for both local control and survival. Neck node recurrence is associated with poor prognosis and low salvage rate.

Abstract
AIM To identify the prognostic significance of different factors in patients with squamous cell carcinoma of the tongue. PATIENTS AND METHODS Seventy-seven patients with carcinoma of the tongue were treated radically at the King Faisal Specialist Hospital and Research Centre between 1980 and 1989. Twenty patients (26%) were treated by resection alone, 11 (14%) with radiotherapy alone, and 46 (60%) with combined resection and radiotherapy. RESULTS Forty-seven patients (61%) had T(1-2), 28 (36%) T(3-4), and two T(x) tumours. The regional nodes were clear in 53 (69%) and contained metastases in 24 patients (31%). Thirty patients (39%) developed recurrences, which were local in 9, regional in 14, locoregional in 5, and locoregional with metastatic disease in 2. The five and 10-year overall actuarial survival for all patients were 65% and 53%, respectively, and the corresponding relapse-free survival 56% and 50%. Univariate and multivariate analyses were done of seven variables - age (<40 compared with >/=40 years), sex, chewing tobacco use, smoking, TNM stage, surgical margins (clear or invaded), and treatment (resection, radiotherapy, or the combination). On univariate analysis chewing tobacco (P=0.04), smoking (P=0.01), invaded resection margins (P=0.04), involved regional lymph nodes (P=0.009), T4 tumours, and patients treated with radiotherapy alone (P=0.001) were associated with poor overall survival. Factors associated with shorter relapse-free survival were age >40 (P=0.03), chewing tobacco (P=0.04), invaded resection margins (P=0.01), and smoking (P=0.01). On multivariate analysis, invaded resection margins and smoking (P=0.04)(P=0.02) were associated with shorter overall survival and relapse-free survival (P=0.03 and (P=0.01), while chewing tobacco independently influenced relapse-free survival only (P=0.03). CONCLUSION Invaded resection margins and smoking were the only independent prognostic factors that affected both overall and relapse-free survival. Those who chewed tobacco were at high risk of locoregional failure.

Abstract
OBJECTIVE This study was designed to determine whether the incidence of squamous cell carcinoma of the oral tongue (SCCOT) in young adults has changed during the past 25 years and to determine prognostic factors for young adult patients (aged < 40 years) with SCCOT. METHODS AND PATIENTS A retrospective review of young adults with SCCOT who sought treatment at the M. D. Anderson Cancer Center between 1973 and 1995 was undertaken. RESULTS The percentage of young adult SCCOT patients at M. D. Anderson increased from 4% in 1971 to 18% in 1993. T stage, N stage, perineural invasion, and lymphatic invasion were all associated with decreased survival. Patients who received a neck dissection as part of their primary treatment had a better chance of survival than patients who did not. CONCLUSIONS The incidence of SCCOT in the young adult population is increasing in the United States. Appropriate surgical management for young adults with SCCOT includes resection of the primary tumor along with a selective node dissection.

Abstract
If the nodes are involved, survival of patients with squamous cell carcinoma of the tongue is considerably reduced. Surgery remains the treatment of choice and, to define its role, we have reviewed 82 consecutive cases. Sixty-two cases (76%) were T1-2, and 46 patients (56%) had involved nodes. The cervical region II was the most often involved (n=26). Occult nodal metastases were present in 12 cases. The extent of nodal spread and prognosis varies according to whether the body or the base of the tongue is involved. Lesions of the base with involved node should be treated by a selective posterolateral neck dissection, whilst in the case of a lesion of the body of the tongue, the dissection should be selective anterolateral. In lesions of the base, when there are no nodes involved, a prophylactic selective posterolateral neck dissection is recommended, whilst in the case of the lesions of the body, selective supraomohyoid neck dissection in T2-4 lesions is recommended.

Abstract
Radiotherapy (RT) used for head and neck cancers causes permanent salivary gland dysfunction (SGD). Previous short-term studies have demonstrated that pre-RT salivary flow rates and the amount of radiation exposure to parotid glands influence the amount of RT-induced SGD. The purpose of this study was to determine which variables are related to the development of long-term post-RT SGD. Parotid flow rates (PFR) were assessed prior to and 1 year after completion of RT in spared parotid glands from 34 patients from 2 parotid-sparing protocols. The results reveal that spared PFR were not significantly higher 1 year post-RT in patients who had high pre-RT PFR, when compared with patients with low pre-RT PFR. However, patients who received higher doses of RT to spared parotid glands had lower PFR 1 year post-RT, compared with patients who had received lower doses of RT. These one-year findings suggest that high pre-RT PFR do not provide protection against RT-induced SGD. Conversely, reduced RT dosages to contralateral parotid glands are protective of PFR after completion of RT.

METHODS The AgNORs area/nucleus was studied in paraffin sections by means of digital image analysis in 43 cases of stage II oral tongue and floor of the mouth SCC. RESULTS Time free of disease was considered a dependent variable of a binary indicator of AgNORs expression (7.77 microns2/nucleus as a cut-off point). High AgNORs level was associated with a statistically significant negative effect on recurrence-free interval of disease in a Cox proportional hazards models controlled for occult lymph node metastasis, involvement of the surgical margins, thickness of the lesion, and vascular invasion. CONCLUSIONS The AgNORs area increased the capability of predicting which patients have a high risk of recurrence of cancer, and its evaluation may provide useful information for the therapeutic approach to the oral tongue and floor of the mouth SCC.

Abstract
A cohort of 433 Oslo patients with head and neck (H/N) carcinomas was analysed for prognostic factors of survival. Mean observation time was 635 days, the distribution of men and women was 2:1 and the mean age was 64.5 years. Tumour localisations were: oral cavity 32.1%, oro/hypopharynx 19.3%, larynx 22.6% and others 25.2%. Stage distribution was: stage I: 21.0%, stage II: 22.6%, stage III: 18.7% and stage IV: 37.4%. Pragmatic strategy showed independent prognostic factors of survival to be gender, age, tumour localisation and stage. A model of predicting 3 year survival was generated. An explanatory approach showed that female patients had a 38% lower risk of mortality compared to male patients after controlling for age, stage and tumour localisation. Comparing observed to expected mortality of the age and gender matched Norwegian population, showed excess risk of death among male compared to female patients when also adjusted for demographic confounders.
