  • Extensive surgical resection of the aerodigestive track can result in a large and complex defect of the oropharynx, which represents a significant reconstructive challenge for the plastic surgery. Development of microsurgical techniques has allowed for free flap reconstruction of oropharyngeal defects, with superior outcomes as well as decreases in postoperative complications. The reconstructive goals for oral and oropharyngeal defects are to restore the anatomy, to maintain continuity of the intraoral surface and oropharynx, to protect vital structures such as carotid arteries, to cover exposed portions of internal organs in preparation for adjuvant radiation, and to preserve complex functions of the oral cavity and oropharynx. Oral and oropharyngeal cancers should be treated with consideration of functional recovery. Multidisciplinary treatment strategies are necessary for maximizing disease control and preserving the natural form and function of the oropharynx.

  • The soft palate of carcinoma limited to the uvular region is infrequent among oropharyngeal cancers. The oropharynx regulates swallowing and speech through dynamic motions. Failure to reconstruct after surgical resection of the oropharynx structure can lead to permanent velopharyngeal insufficiency. Therefore, suitable reconstruction is important in establishing proper functional outcomes while maintaining oncological safety. We present a case of a 66-year-old male who was diagnosed with oropharynx cancer limited in the uvula accompanied by lymph node metastasis. After surgical resection, reconstruction was performed with the united arrangement of bilateral palatal mucomuscular flap and superiorly based posterior pharyngeal flap. There was no aspiration or reflux after feeding and epithelialization completely occurred after 1 month postoperatively. We report a successful case that the reconstruction with the local flap described above could preserve proper oropharyngeal function after primary surgery in small-sized oropharyngeal cancer.

  • Background and Objectives: Multiple primary tumors of the upper aerodigestive tract are not unusual. We examined head and neck cancer patients to discover the presence of second primary cancer in their upper gastrointestinal tract, using esophagogastroscopy. Materials and Methods: Endoscopic examination of the upper gastrointestinal tract was performed on 51 patients whose head and neck cancers were treated at department of therapeutic radiology from August 1996 to April 1999. Two of all patients had been studied by barium swallowing study. In 51 patients, twenty-four had a primary tumor in the larynx, 8 in the oropharynx, 6 in the nasopharynx, 6 in the oral cavity, 6 in the hypopharynx, and 1 in the nasal cavity. Endoscopically pathologic lesions were biopsied. In control group, endoscopy was performed on 1097 patients who didn't complain any symptoms. Results: Endoscopy showed early malignant lesions in 4 cases(7.7%). Histology of esophageal cancers showed squamous cell carcinoma. Malignant lesions of stomach in 2 cases were histologically identified as adenocarcinoma. Two esophageal cancers occurred in patients whose primary lesions had oropharynx and hypopharynx. Two cases of gastric cancer were also accompanied by oropharynx and hypopharynx. The incidence of second primary cancer was 2 in oropharynx and 2 in hypopharynx. In all cases, second primary cancers were found simultaneously. In control group, 9(0.8%) of 1097 patients were confirmed as early esophageal and gastric cancers. Conclusion: The majority of esophageal and gastric cancer detected by endoscopy were early stage in both head and neck cancer and control group. The incidence of esophageal and gastric cancer of head and neck cancer patients was 10 times as high as that of control group. Although followup period was short, all second primary cancers were detected simultaneously. We would recommend that endoscopic evaluation be included in the workup and followup of all patients with newly diagnosed head and neck cancer.

  • Background: The involvement of HPV in oral and oropharyngeal carcinogenesis was first proposed in 2004, based on epithelial HPV tropism and detection of HPV genotypes in oral squamous cell carcinoma samples. While 60-70% of oropharynx tumors may be HPV-positive, only 10 to 19% of tumors of the oral cavity, larynx and hypopharynx appear to have HPV infection. The aim of the study was to evaluate HPV infection associated with oropharyngeal cancer. Materials and Methods: Seventy-eight cases were selected for p16 immunoexpression reactions, and demographic data were collected for comparisons. Results: Most patients were over 60 years old, and 64.1% were smokers. Immunohistochemistry results showed that 86.3% of cases stained positive for p16 protein. Conclusion: The oropharyngeal cancer profile at Erasto Gaertner Hospital presented a high index of smokers over 60 years as well a high number of p16+ tumors, for what we can not determinate the main etiologic factor, but can be aware of the number of patients that presented HPV infection. Since prevention is still the best way to deal with cancer disease, it is important to analyze the interaction of these two etiologic factors and how to detect lesions at an early stage.

  • We assessed the association between frequency of heavy binge drinking and mortality from oropharynx and esophagus cancer after controlling for the total volume of alcohol intake among Korean men. The cohort comprised 2,677 male residents in Kangwha County, aged 55 or older in March 1985, for their upper digestive tract cancer mortality for 20.8 years up to December 31, 2005. For daily binge drinkers versus non-drinkers, the hazard ratios (95% Cls) for mortality were 4.82 (1.36, 17.1) and 6.75 (1.45, 31.4) for oropharyngeal and esophageal cancers, respectively. Even after adjusting for the volume of alcohol intake, we found the hazard ratios for frequency of binge drinking and mortality of oropharyngeal or esophageal cancer to not change appreciably: the hazard ratios were 4.90 (1.00, 27.0) and 7.17 (1.02, 50.6), respectively. For esophageal cancer, there was a strong dose-response relationship. The frequency of heavy binge drinking and not just the volume of alcohol intake may increase the risk of mortality from upper digestive tract cancer, particularly esophageal cancer in Korean men. These findings need to be confirmed in further studies with a larger sample size.

  • Cystic lymph node metastasis of head and neck squamous cell carcinoma(HNSCC) which presumed to be mainly originated from oropharynx including Waldeyer's ring may present as a benign cystic mass on lateral neck such as branchial cleft cyst. Branchial cleft cyst is one of the most common lateral neck cystic mass which may result in regional infection or lymph adenopathy. Many of previously reported literatures showed the incidence of cystic lymph node metastasis from oropharynx including Waldeyer's ring. Preoperative imaging studies and fine needle aspiration cytology cannot provide the accurate results until excision of cystic mass for the diagnostic or therapeutic purpose. Recently, we experienced the rare case of cystic lymph node metastasis from ipsilateral tonsil, which mimicked infected 2nd branchial cleft cyst. Thus, we reported our experience with presentation of case and review of literatures.

  • Objectives: Oropharynx tumors(oral cancer), are caused by tobacco, alcohol consumption, and high-risk human papillomavirus(HPV) infection. Oral squamous cell carcinoma(OSCC) is the most common type of oral cancer and frequently arises from the mucosa of the oropharynx and oral cavity. Despite advances in the diagnosis and treatment(chemotherapy, radiotherapy, and surgery) of oral cancer, over the past two decades, the overall survival rates remains at about 60%. Methods: We pretreated HSC-2 cells with various doses of exposed the cells to eugenol and then we measured cell viability by MTT assay. Results: Cell proliferation was markedly inhibited after eugenol treatment compared to the control. The majority of HSC-2 cells in the control groups showed normal morphology with round regular nuclei. In contrast, apoptotic bodies were seen in the 0.5 mM, 1 mM, 2 mM group. However, the pretreatment with eugenol increased HSC-2 cells apoptosis according to dose-dependency. PI staining quantitatively confirmed the anti-apoptotic effects of propofol. The expression levels of cleaved caspase 3, and Bak significantly increased in HSC-2 cells. Conclusions: These findings indicate that eugenol could be a potential anti-cancer agent for human OSCC and provide valuable data for the development of a novel anticancer strategy.

  • The actual burden of head and neck cancer in India is much greater than reflected through the existing literature and hence can be regarded as a 'tip of iceberg' situation. This has further been evident by the recent reports of 'Net-based Atlas of Cancer in India'. South-east Asia is likely to face sharp increases of over 75% in the number of cancer deaths in 2020 as compared to 2000. Since the percentage increase of Indian population has been nearly twice that of the world in last 15 years there is a likelihood of increase in cancer burden with the same proportion. The distribution of population based cancer registries is grossly uneven with certain important parts of the country being not represented at all and hence the current cancer burden is not reflected by registry data. However, the pathetic situation of health care system in major parts of the country as also emphasized by the World Bank, is not suitable to provide anywhere near accurate data on cancer burden. Head and neck cancer (including thyroid lesions) is third most common malignancy seen in both the sexes across the globe but is the commonest malignancy encountered in Indian males. Also oral cavity cancer is the most prevalent type amongst the males and one of the highest across the globe. This article reviews the latest global and national situation with an especial emphasis on head and neck cancer. Furthermore this review focuses on burden in different sub sites at national and global levels.
