Abstract
Alternative splicing is an important modification process for the genome to generate mature mRNA by transcription, which has been found associated with survival in some tumors. However, systematic analysis of AS events in pan-renal cell carcinoma at the genome-wide level has been seldom conducted yet. In the current study, Upset plot and Venn plot were utilized to present the distribution characteristics of AS events. Those SREs were screened out with multivariate COX regression analyses, and functional enrichment analysis was performed to figure out potential pathways. ROC model was conducted to compare the efficiency of those potential SREs. A total of 2,169, 1,671, and 1,414 SREs were found in renal clear cell carcinoma (KIRC), renal chromophobe cell carcinoma (KICH), and renal papillary cell carcinoma (KIRP), respectively. Functional enrichment analysis results suggested possible mechanism such as changes in the branched-chain amino acid catabolic process due to SREs might play a key role in KIRC. The binary logistic regression equation based on the SREs had a good performance in each model compared to the single factor. The 5 year survival model presented that the AUC of the predicted probabilities in KIRC, KICH, and KIRP were 0.754, 1 and 0.841, and in the diagnostic model were 0.988, 0.970, and 0.999, respectively. Some AS types that were significantly different in pan-RCC and paracancerous tissues have also been discovered to play a role in carcinoma screening. To sum up, alternative splicing events significantly interfere with the prognosis of patients with pan-RCC and are capable as biomarkers for prognosis.

Abstract
The incidence of oropharyngeal squamous cell carcinoma (OPSCC) has markedly increased over the last three decades mostly due to human papillomavirus (HPV)-related infections. Cancers resulting from HPV infection bear a better prognosis than those that are smoking-related. Because HPV-positive patients are often younger, with lower rates of co-morbid illness and longer overall life expectancies, long-term sequelae of therapy have become an important issue. Treatment of oropharyngeal cancers has typically involved the use of radiation and chemotherapy to avoid the morbidity of open surgery which included mandibulotomy and composite resection. Transoral robotic surgery (TORS) is an emerging treatment option for this disease, avoiding the morbidity of open approaches while providing excellent oncologic and functional outcomes. With overall survival rate at 2 years exceeding 80%, and local failure rate of less than 3%, patients receiving TORS report relatively good health-related quality of life (QOL) scores. The aim of the current review is to provide a summary of the current literature with regard to the oncologic and functional outcomes following treatment of OPSCC with TORS.

Abstract
OBJECTIVE To examine the long-term functional and oncologic results in patients who underwent transoral robotic surgery (TORS) as primary therapy or as part of combined therapy for oropharyngeal squamous cell carcinoma arising in the tonsil or base of tongue. PATIENTS AND METHODS We reviewed a prospective TORS database of patients with squamous cell carcinoma arising in the tonsil or base of tongue treated between March 2007 and February 2009 to determine oncologic outcomes at 24 months or more of follow-up. The presenting tumor stage, histopathologic factors, surgical margins, and adjuvant treatment extent were evaluated. Functional outcomes included gastrostomy tube dependence and tracheostomy dependence. Oncologic outcomes included local, regional, and distant control and disease-specific and recurrence-free survival. RESULTS A total of 66 TORS patients were followed up for a minimum of 2 years. Most (97.0%; 64 of 66) were able to eat orally within 3 weeks after surgery before starting adjuvant therapy. Long-term gastrostomy tube use was required in 3 of the 66 (4.5%) and long-term tracheotomy in 1 (1.5%). Three-year estimated local control and regional control were 97.0% and 94.0%, respectively. Two-year disease-specific survival and recurrence-free survival were 95.1% and 92.4%, respectively. CONCLUSION With appropriate adjuvant therapy, TORS achieves excellent functional results for patients with oropharyngeal squamous cell carcinoma. Oncologic outcomes are equivalent or superior to results of other surgical and nonsurgical treatments.

Abstract
Objective. To analyze outcomes in patients with squamous cell carcinoma (SCCA) of the tonsil from the years 1998 to 2006. To assess factors that may affect disease-specific survival, such as patient characteristics and/or treatment modality. Study Design and Setting. National Cancer Institute’s Surveillance Epidemiology and End Results (SEER) program. Subjects and Methods. The SEER database was used to perform a population-based cohort analysis for patients diagnosed with SCCA of the tonsil from 1998 to 2006. Disease-specific survival was correlated with sex, age, ethnicity, year of diagnosis, and treatment modality in a univariate Cox proportional hazards analysis and a multiple Cox-regression model with and without interaction effect. Results. Applied inclusion criteria resulted in 8378 patients. Of this patient cohort, 80% were male and 85% were white. The mean patient age at diagnosis was 58.1 years. On univariate and multivariate analyses, ethnicities other than white carried a significantly higher rate of disease-specific death (hazard ratio = 1.71, P < .001). Each additional year of age at the time of diagnosis carried approximately a 4% increase in likelihood of disease-specific death. With each passing year of time at diagnosis, patients carried a decreased risk of disease-specific death ( P < .001); this value was significant in all 3 statistical models. Patients who underwent external-beam radiation had a higher likelihood of disease-specific survival with each passing year at time of diagnosis. Conclusion. Population analysis based on the SEER database reveals increased disease-specific survival from tonsillar SCCA in more recent years. This may be because of earlier diagnosis, an increase in less aggressive subtypes of SCCA, and more effective treatment modalities.

Abstract
OBJECTIVES The tonsillar fossa is the most common subsite of the oropharynx to be afflicted with squamous cell carcinoma (SCCA). Accepted treatments include any combination of surgery, radiotherapy, and chemotherapy. We review the oncologic and functional outcomes of patients with tonsillar carcinoma who underwent transoral tumor resection and neck dissection with or without postoperative radiotherapy or chemoradiotherapy. STUDY DESIGN Retrospective chart review. METHODS From 1996 through January 2005, 102 patients with tonsillar SCCA underwent transoral resection. Overall survival, disease-specific survival, local control, and locoregional control rates were analyzed using the Kaplan-Meier method. Immediate and long-term speech and swallowing function and treatment-related morbidity were analyzed. RESULTS Twenty-six patients had surgery only, 71 had surgery and radiotherapy, and five had surgery and chemoradiotherapy. Twenty patients had stage III disease, 63 had stage IVA disease, and two had stage IVB disease. The Kaplan-Meier overall survival estimate was 92.2% at 2 years and 85.0% at 5 years. The 5-year local control estimate was 91.8%, and the 5-year Kaplan-Meier disease-specific survival estimate was 93.9%. The median hospital stay was 3 days. Tracheostomy was required for 14 patients, and 13 of these patients had decannulation. Temporary feeding tubes were placed in 35 patients. Sixteen patients received a percutaneous endoscopic gastrostomy tube; of these, 12 had the tubes removed. CONCLUSIONS Transoral resection of tonsillar SCCA with or without postoperative adjuvant therapy provided excellent locoregional control and minimized treatment-related morbidity. We believe that transoral resection is the optimal treatment for patients with oropharyngeal SCCA.

Abstract
Traditionally, risk factors for the development of tonsil cancer include the use of alcohol and/or tobacco, however a significant proportion of new cases develop in young patients without these risk factors. Recent investigation suggests that human papilloma virus (HPV) may serve as an etiology in such cases and represent a unique risk factor in a sub-set of patients. Irrespective of the etiology, in the majority of cases early carcinoma of the tonsil can effectively be treated using single modality therapy. While local-regional control and survival are similar following surgery or radiotherapy, primary surgery can be accomplished with minimal functional morbidity while reserving radiation for recurrent disease. In contrast, surgical salvage following external beam radiotherapy can be technically challenging and is often associated with a significant increase in surgical complications and functional morbidity. In contrast to early tonsillar disease, advanced tonsil cancer represents a clinical challenge that requires multimodality therapy. While advanced lesions are often treated with a combination of radiation, chemotherapy, and surgical ablation, management of the neck and distant metastases continues to present a therapeutic dilemma.

Abstract
BACKGROUND The treatment of patients with squamous cell carcinoma (SCC) of the oropharynx remains controversial. No randomized trial has addressed adequately the question of whether surgery (S), radiation therapy (RT), or combined treatment is most effective. METHODS Treatment results from North American academic institutions that used S with or without adjuvant RT (S +/- RT) or used RT alone or followed by neck dissection (RT +/- ND) for patients with SCC of the tonsillar region or the base of tongue were compiled through a MEDLINE search (from 1970 to August, 2000) and from the references cited in each report. Studies were eligible for inclusion if they contained direct, actuarial (life-table), or Kaplan-Meier calculations for the following end points: local control, local-regional control, 5-year absolute survival, 5-year cause specific survival, or severe or fatal treatment complications. Weighted average results, which took into account series size, were calculated for each end point for the purposes of treatment comparison. Results and conclusions were based on data from 51 reported series, representing the treatment of approximately 6400 patients from the United States and Canada. RESULTS The results for patients with SCC of the base of tongue who underwent S +/- RT versus RT +/- ND, respectively, were as follows: local control, 79% versus 76% (P = 0.087); local-regional control, 60% versus 69% (P = 0.009); 5-year survival, 49% versus 52% (P = 0.2); 5-year cause specific survival, 62% versus 63% (P = 0.4); severe complications, 32% versus 3.8% (P < 0.001); and fatal complications, 3.5% versus 0.4% (P < 0.001). The results for patients with SCC in the tonsillar region who underwent S +/- RT versus RT +/- ND, respectively, were as follows: local control, 70% versus 68% (P = 0.2); local-regional control, 65% versus 69% (P = 0.1); 5-year survival, 47% versus 43% (P = 0.2); 5-year cause specific survival, 57% versus 59% (P = 0.3); severe complications, 23% versus 6% (P < 0.001); and fatal complications, 3.2% versus 0.8% (P < 0.001). CONCLUSIONS The information in this article provides a useful benchmark for evidence-based counseling of patients with SCC of the oropharynx. The rates of local control, local-regional control, 5-year survival, and 5-year cause specific survival were similar for patients who underwent S +/- RT or RT +/- ND, whereas the rates of severe or fatal complications were significantly greater for the S +/- RT group. Furthermore, available data on the functional consequences of treatment suggest the superiority of RT +/- ND. The authors conclude that RT +/- ND is preferable for the majority of patients with SCC of the oropharynx.

Abstract
BACKGROUND The management of tonsil carcinoma has gradually evolved such that the literature is replete with outcome summaries of this disease treated with primary RT and chemotherapy. Recently there have been no reports of patient outcomes with primary surgical therapy. Nonsurgical treatment is warranted when tumors are unresectable or if the patient refuses surgery. Our policy has been to treat operable squamous cell carcinoma (SCCA) of the tonsil with surgery. The decision to use adjuvant therapy is based on the surgical and histologic findings. We herein report our results with this treatment protocol. METHODS A retrospective review of 162 patients with SCCA of the tonsil was performed. Eighty-four patients were treated with surgery, which was followed by RT and/or chemotherapy if histologic signs of aggressive behavior were identified. Patients were followed 2 to 15 years after treatment. RESULTS Of the 9 patients with stage I disease, 89% are without evidence of recurrent disease and 91% of patients with stage II tonsil cancers are also disease free. The survival rates for stage III and stage IV cancer patients are 79 and 52%, respectively. CONCLUSION Our data suggest that patients with early tonsil cancer can be effectively treated with surgery. Surgery allows pathologic staging so that patients with advanced tumors can be treated with adjuvant therapy.
