The objectives of treating oropharyngeal cancer are complete removal of tumor, restoration of function and aesthetics, and such treatments require adequate exposure for direct visual and bimanual examination. It presents challenges for the head and neck oncologist. A thorough evaluation is necessary to stage these tumors appropriately. Surgical treatment requires addressing the primary tumor and also neck disease, reconstructive techniques, and associated morbidities. A multidisciplinary approach helps balance the tumor stage, patient's comorbidities, functional outcome, and patient's wishes, thereby maximizing patient outcomes.

PURPOSE: We tried to evaluate the role of conventional radiotherapy alone or with neoadjuvant chemotherapy in oropharyngeal cancerin terms of survival rates and to identify prognostic factors affecting survival by retrospective analysis. METHODS AND MATERIALS: Forty seven patients of oropharyngeal cancer were treated by conventional radiotherapy in our hospital from Nov. 1985 to Apr.1993. Of these. twenty six patients were treated by conventional radio therapy alone. and 21 patients with neoadjuvant chemotherapy of mostly two or more cycles of cisplatin and pepleomycin. The patient characteristics of radiotherapy alone group and neoadjuvant chemotherapy group were not different generally. Radiotherapy was performed by 6MV-LINAC and the total radiation doses of primary tumors were 54.0-79.2 Gy and cervical lymph nodes were 55.8-90.0 Gy with a fraction size of 1.8 or 2.0 Gy per day. The rangeof follow-up periods was 3-102 months and median was 20 months. The range of age was 33-79 years old and median was 58 years old. RESULTS: Overall 3-year actuarial survival rate (3YSR) of all patients was 39%. The 3YSRs of stage I (n=5), II (n=11), III (n=12) and IV (n=19) were 60, 55,33 and 32% respectively. The 3YSRs of T1+2, T3+4 and No, N+ were 55, 18% (p=0.005) and 43,36% (p>0.1), respectively. There was no difference in 3YSRs between radiotherapy alone group and neoadjuvant chemotherapy group (38 vs 43%, p>0.1). According to the original site of primary tumor, the 3YSRs of tonsil (n=32), base of tongue (n=8), soft palate or uvula(n=6) and pharyngeal wall (n=1) were 36,38,67 and 0%, respectively. The patients of soft palateor uvular cancer had longer survival than other primaries but the difference was not significant statistically (p>0.1). Of 32 patients of tonsillar cancer, 22 patients who had primary extension to adjacent tissue showed inferior survival rate to the ones who had not primary extension, but the difference was marginally significant (24 vs 60%, p=0.08). On Cox multivariate analysis in entire patients with variables of age. T stage. N stage. total duration of radiotherapy, the site of primary tumor and the use of neoadjuvant chemotherapy. only T stage was a significant prognostic factor affecting 3YSR. CONCLUSION: The difference of 3YASRs of conventional radiotherapy alone group and neoadjuvant chemotherapy group was not significant statistically. These treatments could be effective in oropharyngeal cancer of early stage, especially such as soft palate, uvular or tonsillar cancer which did not extend to adjacent tissue. But in order to improve the survival of patients of most advanced oropharyngeal caner, other altered fractionated radiotherapy such as hyperfractionation rather than conventional fractionation or multimodel approach combining radiotherapy and accessible surgery or concurrent chemotherapy might be beneficial.

OBJECTIVES: Although human papillomavirus (HPV) infection is considered as a favorable prognostic factor in oropharyngeal cancer, the prognosis of HPV-associated tonsil cancer has rarely been studied especially when surgery was the main treatment. In this study, the authors investigated the effect of p16 over-expression (HPV infection) on tonsil cancer prognosis according to the type of treatment, HPV presence by PCR, and expression of p53 and epidermal growth factor receptor (EGFR) by immunohistochemistry (IHC). METHODS: Medical records of 33 tonsil cancer patients were reviewed. Using formalin-fixed and paraffin-embedded tumor specimens, PCR-based genotyping of HPV and IHC of p16, p53 and EGFR were performed. The effects of HPV presence and the expression of IHC markers were analyzed on the recurrence-free survival. Five-year disease-free survival (DFS) rates were evaluated according to p16 expression status. RESULTS: An over-expression of p16 was observed in 27 (81.9%) out of 33 cases. Surgery-based treatment was provided for 21 (63.6%) patients. There was no association between p16 immunoreactivity and HPV presence, nor with p53 and EGFR expression. Regardless of main treatment modalities, five-year DFS did not differ by p16 expression status (P=0.051). However, over-expression of p16 was associated with a lower recurrence in multivariable analyses (P=0.046). CONCLUSION: Regardless of main treatment modalities, an over-expression of p16 (HPV infection) is associated with a lower recurrence in tonsil cancers. However it is not associated with simple HPV presence or p53 and EGFR over-expression.

OBJECTIVES: The purpose is to provide detailed estimates of population-based incidences of head and neck cancers (HNCs) between 1999 and 2012 in South Korea and to evaluate trends. METHODS: Data was reviewed from the Korea National Cancer Incidence Database regarding the incidence of HNCs between 1999 and 2012. Locations that were surveyed included lip, oral tongue, oral cavity, major salivary gland, nasopharynx, nasal cavity and paranasal sinus, tonsil, hypopharynx, oropharynx, and larynx. Age-standardized incidence rates were calculated and provided with 95% confidence intervals. The increase ratio of HNCs for and male-to-female ratios were also calculated. RESULTS: The incidence of lip (0.07–0.10/100,000 people) and oropharyngeal cancer (0.09–0.12/100,000 people) remained low during the study period while laryngeal cancer (1.17–2.08/100,000 people) occurred most frequently. The incidence of oral tongue, major salivary gland, tonsil, and hypopharynx increased steeply compared to other HNCs between 1999 and 2012. Male-to-female ratio was over 1.0 for all HNCs, especially for those of tonsil, hypopharynx, oropharynx, and larynx cancer which were >5.0. CONCLUSION: The incidence of all the HNCs except for laryngeal cancer has increased yearly in men and women in South Korea since 1998. Rates of oral tongue, major salivary gland, and tonsil cancer have increased the most rapidly during this time period.

BACKGROUND AND OBJECTIVES: In order to eradicate the disease and preserve function of oropharynx and facial contour, appropriate surgical approach should be chosen for surgical treatment of oropharyngeal cancer. This study was performed to evaluate the usefulness and effectiveness of various surgical approaches in the surgical treatment of oropharyngeal cancer. SUBJECTS AND METHOD: We analyzed 65 patients with oropharyngeal cancer who underwent surgery as a primary treatment from Jan. 1994 to Jun. 2009, retrospectively. Primary tumor site, TNM stage, surgical approach, management of neck, reconstruction method, complication, recurrence rate were analyzed to assess advantages and disadvantages of various surgical approaches. RESULTS: The surgical approaches applied were transoral approach in 25, mandibulotomy in 23, lower cheek flap in 4, trans-pharyngeal in 9, and mandibular lingual releasing approach in 4. Most of T1 lesion was resected by transoral approach (65.0%). For advanced T3 and T4, mandibulotomy was mainly used. Lateral pharyngotomy and mandibular lingual release approach were used for the surgery of moderate size of oropharyngeal cancer. The locoregional recurrence rate did not differ according to different surgical approaches with regard to T and N stages. CONCLUSION: Transoral approach is very useful for the most of small oropharyngeal cancer. Mandibulotomy provides most wide surgical view for advanced T3, T4 oropharyngeal cancer.

The number of new cases of oropharyngeal cancer is increasing year by year among the world, and HPV infection is one of the risk factors for this malignant tumor. Compared with HPV-negative oropharyngeal cancer, HPV-positive patients are more sensitive to radiotherapy and have a better prognosis, but there is no accepted treatment for HPV-positive patients. Reducing treatment intensity moderately and exploring the best option to minimize side effects of treatment are urgent issues to be addressed. This article reviews the research progress on the treatment improvement of HPV-associated oropharyngeal cancer in recent years.

OBJECTIVETo explore a better approach to resect the advanced oropharyngeal carcinoma.

METHODSFrom 1995 to 2005, 17 patients underwent mandibular swing procedure for excision of advanced oropharyngeal carcinoma including: 13 tonsillar cancers, 2 soft palate carcinomas and 2 lingual root cancers. Surgical procedure was selected according to the lesion. All tumors were resected through the mandibular swing approach or its combined approaches. Immediate reconstruction of the surgical defect was done using tongue flap, pectoralis major myocutaneous flap, sternohyoid myofascial flap, temporalis myofascial flap and forehead flap, respectively. After surgical resection of the tumors, all patients received postoperative radiotherapy.

RESULTSAll patients' advanced oropharyngeal carcinoma were successfully resected as planned through the mandibular swing procedure or its combined procedures without severe complications. Functions of deglutition, respiration and speech were well restored. The 3- and 5-year survival rate was 54. 5% and 40%, respectively.

CONCLUSIONThe mandibular swing procedure and its combined approach is safe and effective in the surgical resection of the advanced oropharyngeal carcinoma, which can provide a good exposure for the oropharynx, supraglottic region, hypopharynx, the parapharyngeal space and the base of the skull.

Thirty-six patients (24 with oral cavity or oropharynx cancers and 12 larynx cancers) were prospectively examined with computed tomography (CT) to determine its value in staging the primary tumor and to compare with the clinical staging. The CT staging agreed with the clinical staging in 50% (12/24) of the oral cavity or oropharynx cancers and in 67% (8/12) of the larynx cancers. The CT upgraded the clinical staging in 29% (7/24) of the oral cavity or oropharynx tumors and in 33% (4/12) of the larynx cancers, whereas the CT downgraded the clinical staging in 21 % (5/24) of the oral cavity or oropharynx cancers. There is no downgrade on CT in larynx cancer. The post-surgical confirmation was not made in most of the cases. The possible causes of disagreement between the CT and the clinical staging, and the diagnostic value of the CT in evaluation of the primary tumor in oral cavity, oropharynx and larynx were discussed.
