Tongue SCC (tongue + scc)
Selected AbstractsThe national cancer data base report on squamous cell carcinoma of the base of tongue,,HEAD & NECK: JOURNAL FOR THE SCIENCES & SPECIALTIES OF THE HEAD AND NECK, Issue 8 2004Weining Zhen MD Abstract Background. 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.

However, recent studies have shown that FADD also plays an important role in the growth and regulation of the cell cycle. The purpose of this study was to elucidate the role of FADD in oral squamous cell carcinoma (SCC). Methods:, The DNA amplification of FADD from 30 samples of tongue SCC was analyzed using real-time PCR and the protein expression of FADD from 60 samples of tongue SCC was analyzed using immunohistochemistry. Results:, The DNA amplifications of FADD were observed in 13 cases (44.3%) and were significantly correlated with the histopathological differentiation grade of SCCs (P = 0.009). FADD expression levels compared with the matched adjacent epithelium increased significantly (P = 0.000). Additionally, the positive expressions of FADD were significantly correlated with lymph node metastasis of SCCs (P = 0.029) and the 5-year disease-specific survival rates (P = 0.049). A positive association between FADD expression level and the histopathological differentiation grade was found to be limited to T1 SCCs (P = 0.019). DNA amplification was moderately correlated (correlation coefficient = 0.406, P = 0.026) with expression of FADD in 30 samples of tongue SCC. Conclusion:, In tongue SCCs, the expression of FADD was higher when compared with that of adjacent areas, which might be determined via genomic amplification in 11q13.3. Thus, SCC cells with the expression of FADD are possibly more likely to become metastatic and to worsen survival rates.

Hessel MD Abstract BACKGROUND: The objective of this study was to identify measurable parameters that provide quality data for assessing how well cancer care adheres to accepted treatment guidelines and is delivered to any given patient with oral tongue cancer. METHODS: A retrospective chart review included 116 patients treated for T1-T2/N0-N1 squamous cell carcinoma (SCC) of the oral tongue between 1998 and 2003. A set of quality measures considered critical for outcome included: 1) accurate TNM staging at presentation, 2) documentation of margin status, 3) appropriate referral for adjuvant radiation therapy, and 4) neck dissection for depth of invasion >4 mm. In addition, 26 clinical endpoints involving pretreatment assessment, staging, treatment, surveillance, and symptom control were analyzed. RESULTS: Patients comprised 73 men and 43 women (median age, 57 years). Forty-one (35.3%) patients presented with stage I disease, 61 (52.6%) with stage II, and 14 (12.1%) with stage III. The overall 5-year survival rate for all patients was 68.6%. There was a 90.5% compliance with TNM staging at presentation, 99.1% for documentation of margin status, 98.2% for adequate referral to radiation therapy, and 88.7% for appropriate neck dissection based on depth of invasion. Compliance with clinical endpoints was variable and ranged from 100% for endpoints related to radiation therapy to <40% for endpoints related to speech pathology and rehabilitation. CONCLUSIONS: Overall compliance with documenting the 4 parameters designated as quality measures for treatment of oral tongue SCC was acceptable, thus demonstrating that it is possible to use these data for measuring effective cancer care.

[source] Tongue and tonsil carcinomaCANCER, Issue 9 200544 years, Increasing trends in the U.S. population ages 20 Abstract BACKGROUND An increasing incidence of oral carcinoma among young adults has been reported in the U.S. and Europe. Although the association between human papillomavirus infection and tonsillar carcinoma is now well established, to the authors' knowledge little is known about incidence trends in tonsillar carcinoma among younger adults. The objective of the current study was to explore the trends in both oral cavity and pharyngeal squamous cell carcinoma (SCC) in younger U.S. populations, in particular tongue and tonsillar SCC. METHODS Using the 1973,2001 Surveillance, Epidemiology and End Results (SEER) database, we computed age, race, and site-specific trends of oral and pharyngeal (excluding nasopharynx) carcinoma incidence rates. The percent change (PC) and annual percent change (APC) were computed to explore trends in incidence rates over time. RESULTS There were 2262 SCC of the oral cavity and 1251 SCC of the pharynx reported to the SEER program from 1973 to 2001 in adults aged 20,44 years. There was a statistically significant increase in the incidence of oral tongue SCC (APC = +2.1; P < 0.001), base of tongue SCC (APC = +1.7; P = 0.04), and palatine tonsil SCC (APC = +3.9; P < 0.001) among younger white individuals, whereas the incidence of SCC in all other oral and pharyngeal sites decreased or remained constant. CONCLUSIONS The increase in tonsil SCC incidence from 1973 to 2001 paralleled the increase in tongue SCC, whereas SCC in all other oral and pharyngeal sites remained constant or decreased. This may suggest similar etiologic factors for SCC affecting the palatine tonsils and tongue in younger populations. Cancer 2005. © 2005 American Cancer Society. [source] | ||||||||||
