Tongue Squamous Cell Carcinoma (tongue + squamous_cell_carcinoma)
Selected AbstractsExternal Beam Radiation Followed by Planned Neck Dissection and Brachytherapy for Base of Tongue Squamous Cell Carcinoma,THE LARYNGOSCOPE, Issue 10 2000David M. Kaylie MD Abstract Background Surgical resection of tongue base cancer can leave the patient with significant functional deficits. Other therapies, such as external beam radiation followed by neck dissection and radiation implants, have shown equal tumor control with good functional outcome. Methods Between March 1991 and July 1999, 12 patients at Oregon Health Sciences University, the Portland Veterans Administration Medical Center and West Virginia University School of Medicine Hospital were treated with external beam radiation followed by neck dissection and Ir192 implants. Two patients had T1 disease, two had T2, five patients had T3 tumors, and three had T4 tumors. Six had N2a necks, three had N2b necks, and three had N2c. Follow-up ranged from 13 months to 8 years. Results After external beam radiation, five patients had complete response and seven had partial response in the neck without complications. One patient underwent a unilateral radical neck dissection, eight had unilateral selective neck dissections involving levels I to IV, and three had dissections involving levels I to III. One of the five patients who had a complete clinical response in the neck had pathologically positive nodes. One patient had a pulmonary embolus that was treated and had no permanent sequelae. There were three complications from brachytherapy. Two patients had soft tissue necrosis at the primary site and one patient had radionecrosis of the mandible. All healed without further therapy. One patient had persistent disease and underwent a partial glossectomy but died of local disease. Distant metastasis developed in two patients. All others show no evidence of disease and are able to eat a normal diet by mouth. Conclusion This combination of therapies should be considered when treating tongue base cancer.

To assess tissue characterization of oral tongue cancer and prediction of subclinical cervical lymph node metastasis, we investigated whether intraoral ultrasonography could be used in conjunction with a computer-aided diagnosis (CAD) system. Methods. The study population comprised 109 patients with presurgical, clinical T1N0 or T2N0 oral tongue squamous cell carcinoma who underwent partial glossectomy. All the patients were examined by preoperative intraoral and postoperative exvivo ultrasonography. To evaluate the ultrasonic imagesquantitatively, ultrasonographic parameters from tumor contour features were computed by using the proposed CAD system. The imaging results were correlated with histopathologic findings. Results. Oral tongue cancer was clearly identified in all patients by intraoral ultrasonography. Ultrasonic images of oral tongue cancer reflected the histopathologic structures. Subclinical cervical lymph node metastasis was predicted by intraoral ultrasonography. In a logistic regression analysis using the proposed CAD system, the diagnostic sensitivity, specificity, and accuracy for prediction of subclinical lymph node metastasis were 87.2%, 84.3%, and 85.3%, respectively. Conclusions. Intraoral ultrasonography in conjunction with the proposed CAD system allows tissue characterization and prediction of subclinical cervical lymph node metastasis. © 2006 Wiley Periodicals, Inc.

This study provides the largest contemporary overview of presentation, care, and outcome for base of tongue squamous cell carcinoma (SCC). Methods. We extracted 16,188 cases from the National Cancer Data Base (NCDB). Chi-square analyses were performed on selected cross-tabulations. Observed and disease-specific survival were used to analyze outcome. Results. Three-quarters had advanced-stage (III,IV) disease. Radiation therapy alone (24.5%) and combined with surgery (26.9%) were the most common treatments. Five-year observed and disease-specific survival rates were 27.8% and 40.3%, respectively. Poorer survival was significantly associated with older age, low income, and advanced-stage disease. For early-stage disease, surgery with or without irradiation had higher survival than irradiation alone. For advanced-stage disease, surgery with irradiation had the highest survival. Conclusions. Survival rates were low for base of tongue SCC, with most deaths occurring within the first 2 years. Income, stage, and age were significant prognostic factors. In this nonrandomized series, surgery with radiation therapy offered patients with advanced-stage disease the best survival. © 2004 Wiley Periodicals, Inc.

The results will have important implication for the management of patients. Patients and Methods Seventy-two clinically T1 and T2 glossectomy specimens of oral tongue carcinoma were serially sectioned in 3-mm thickness for the evaluation of various pathologic features. The prognostic value in the prediction of subclinical nodal metastasis, local recurrence, and survival of different models were compared. Results Among all the tumor parameters and predictive models being evaluated, tumor thickness was the only significant factor that had significant predictive value for subclinical nodal metastasis, local recurrence, and survival. With the use of 3-mm and 9-mm division, tumor of up to 3-mm thickness has 8% subclinical nodal metastasis, 0% local recurrence, and 100% 5-year actuarial disease-free survival; tumor thickness of more than 3 mm and up to 9 mm had 44% subclinical nodal metastasis, 7% local recurrence, and 76% 5-year actuarial disease-free survival; tumor of more than 9 mm had 53% subclinical nodal metastasis, 24% local recurrence, and 66% 5-year actuarial disease-free survival. Conclusions Tumor thickness should be considered in the management planning of patients with early oral tongue carcinoma. © 2002 Wiley Periodicals, Inc.

Veness Background: Mucosal head and neck cancers usually occur in older males after years of smoking and alcohol abuse. Despite this, approximately 5% of cases occur in young adults. The aetiology remains unclear and the anterior tongue is a prevalent site. Prognosis has been reported as worse in young patients and some have proposed a more aggressive treatment approach. Methods: Patients diagnosed with previously untreated anterior tongue squamous cell carcinoma and treated with curative intent were identified. Retrospective and prospective data were collected. Univariate and multivariate analyses were undertaken using Cox regression analysis. The outcome of patients treated with anterior tongue cancer using a cut-off age of 40 years was compared. Results: Between 1980 and 2000, 106 males and 58 females with anterior tongue squamous cell carcinoma were treated at Westmead Hospital. Median follow up was 47 months (6,210 months). Twenty-two patients (13.4%) were aged ,40 years. Other than age, patient demographics, TNM stage and treatment approach were similar between the two groups. Eighty-one per cent had either a T1 or T2 primary. In total, 139 patients (84.8%) had surgery or surgery and radiotherapy. A total of 56 (34%) patients experienced a recurrent event, with nodal recurrence occurring most often as the first site (n = 33, 59%). Young patients had a higher recurrence rate (45.5% vs 32.4%; P = 0.23). Relapse-free survival at 5 years was 62% versus 81% (P = 0.27). Overall survival at 5 years was 65% versus 67% (P = 0.74). Conclusions: In keeping with recently published evidence, young age at diagnosis with anterior tongue cancer did not portend worse outcome. There is therefore currently no strong evidence to support a different treatment approach in young patients. [source] Tongue cancer patients have a high frequency of allelic loss at the von Hippel-Lindau gene and other loci on 3pCANCER, Issue 3 2008Takeshi Asakawa MD Abstract BACKGROUND. Although genetic abnormalities on 3p have been suggested to be linked to the development of squamous cell carcinoma of the head and neck, to the authors' knowledge no study to date has examined such genetic abnormalities in patients with squamous cell carcinoma of the tongue. In the current study, loss of heterozygosity (LOH) was evaluated at several loci within 3p, including the von Hippel-Lindau gene (VHL), in samples of tongue squamous cell carcinoma. In addition, the coding region of the intact VHL allele was screened for sequence mutations. METHODS. DNA was extracted from tumor and nontumor tissues collected from 28 patients with tongue squamous cell carcinoma. LOH was investigated by analysis of single nucleotide polymorphisms within exon 3 of VHL and by microsatellite analysis within another 10 loci. Mutation analysis of the VHL gene was performed by polymerase chain reaction (PCR) amplification and sequencing of the coding region of the gene. RESULTS. LOH within VHL was found at a high frequency (45.5%) within the tumor. However, mutations of the VHL gene were not detected in all tumor samples. LOH of other microsatellite markers on 3p was observed in 27.3% to 50% of tumor samples. Eleven (58%) of 19 samples that were informative at more than 2 loci exhibited LOH of at least 1 locus; 10 of these 11 cases exhibited LOH at multiple loci. CONCLUSIONS. A wide range of deletions in 3p, including at the VHL gene, may play a role in the development of tongue cancer. Cancer 2008. © 2007 American Cancer Society. [source] | ||||||||||
