Visual screening of oral cavity cancer: The role of otolaryngologists

OBJECTIVES: Because most screening was done by dentists, the purpose of this prospective cohort study was to evaluate the effectiveness of oral visual screening by otolaryngologists. In addition, we wanted to determine which group of enrolled patients was at potential risk of contracting oral cancer. METHODS: All male patients age > or =18 years who visited our clinic received oral mucosal screening. Basic data, including personal habits, were also obtained. A multivariate logistic regression model was devised to determine relevant risk factors for developing oral cancer. RESULTS: A total of 5,825 patients were enrolled in this study. Positive findings were found in 226 patients (3.9%). One hundred seventy-two patients received biopsy and 131 patients were proven to have oral cancer (sensitivity rate: 76.2%). The results showed that those who smoked, consumed alcohol, and chewed betel quid on a regular basis were most likely to contract oral cancer (odds ratio = 49.81, 95% confidence interval = 29.38-84.42). CONCLUSIONS: The otolaryngologists involved in this study successfully performed the oral screening. The sensitivity and specificity rates were both satisfactory. We suggest that those who are habitual cigarette smokers, alcohol consumers, and betel quid chewers should receive oral mucosal screening regularly so that potential oral cancer can be detected as early as possible.     

The expression of epidermal growth factor receptors in the oral mucosa of patients with oral cancer

Summary Representative tumor samples and mucosal samples were taken from three different groups of patients and were stained immunohistochemically for their expressions of epidermal growth factor receptors (EGFR). Patients in group 1 had oral squamous carcinoma, with specimens taken from the tumor as well as from the mucosa without tumor invasion. Patients in group 2 had no evidence of tumor but had heavy drinking and smoking habits. Tumor-free patients who do not drink or smoke served as the control group. The findings in the present study showed that the tumor and mucosal samples from groups 1 and 2 had increased EGFR expression while the control group showed significantly less EGFR. These results suggest that EGFR may play a role in the development of premalignant tissue changes, which are probably influenced by chronic toxic irritation.Presented at the XXI Pan American Congress of Otolaryngology, Head and Neck Surgery, Bahia-Salvador, Brazil, 2 November 1988     

Early detection of premalignant lesions and oral cancer

Cancers of the oral cavity account for approximately 3% of malignancies diagnosed annually in the United States. As with other upper aerodigestive tract cancers, 5-year survival rates for oral cavity cancers decrease with delayed diagnosis. Cancers of the oral cavity are thought to progress from premalignant/precancerous lesions, beginning as hyperplastic tissue and developing into invasive squamous cell carcinoma. Despite the general accessibility of the oral cavity during physical examination, many malignancies are not diagnosed until late stages of disease. To prevent malignant transformation of these oral precursor lesions, multiple screening and detection techniques have been developed to address this problem.     

The association of smoking, alcoholic consumption, betel quid chewing and oral cavity cancer: a cohort study

We aimed to analyze the relationship between smoking, alcoholic consumption and betel quid chewing with oral cavity cancer. All male patients age ≥18 years who visited our clinic received an oral mucosal inspection. Basic data including personal habits were also obtained. A multivariate logistic regression model was utilized to determine relevant risk factors for developing oral cavity cancer. A total of 8,356 patients were enrolled in this study. Abnormal findings were found in 382 patients (4.6%). Two hundred and ninety-seven patients received biopsy and 191 patients were proven to have oral cavity cancer. The results of multivariate logistic regression showed that those who smoked, consumed alcohol and chewed betel quid on a regular basis were most likely to contract oral cancer (odds ratio: 39.66, 95% confidence interval: 26.04–60.38). Therefore, habitual cigarette smokers, alcohol consumers, and betel quid chewers have a higher risk of contracting oral cavity cancer and should receive oral mucosal screening regularly so potential oral cavity cancer can be detected as early as possible, which may result in better and improved survival of oral cancer patients.     

A neonate with cleft palate and a fetal mass in the oral cavity: a rare case of an oral fetus-in-fetu

Fetus-in-fetu is a rare congenital condition in which a malformed fetus-like structure is found in the body of its twin. We report a unique case of a male neonate with cleft palate and a fetus-like structure arising in his oral cavity. The neonate underwent emergent surgical removal of the mass immediately after delivery. Radiological and pathological studies of the resected mass provided supportive evidence for the case of an oral fetus-in-fetu. To our knowledge, there are few cases of oral fetus-in-fetu in the literature. Moreover, the presence of cleft palate in this neonate is of potential interest and clinical importance.     

Bilateral lingual artery stenosis: A rare,late complication of chemoradiotherapy

Introduction

Carotid artery stenosis following radiotherapy (RT) is a known risk factor for the development of cerebrovascular disease with a risk of subsequent stroke or transient ischaemic attack. In contrast, small vessel disease in the neck following RT has been more rarely described.

Efficacy and safety of a vessel sealing system in oral cancer resection and reconstructive surgery

Objective: Currently, many studies are being performed that focus on the efficacy and safety of the vessel sealing system (VSS) in various fields of surgery. However, in the field of oral cancer surgery, the efficacy and safety of VSS use have not been clarified.

Methods: One hundred and fifty-one patients underwent oral cancer resection and reconstructive surgery. They were divided into two groups: Ligasure vessel sealing system (LVSS) group and conventional surgery (CS) as control. Intra-operative blood loss, operating time, and incidence of post-operative complications and recurrence were analyzed.

Results: LVSS use significantly reduced intra-operative blood loss. The operating time was shortened only in mandibular gingiva cancer surgery. There were no differences between the two groups with regard to the incidence of post-operative complications and recurrence.

Conclusions: LVSS use was found to be effective and proved to be efficient and safe, and may be useful in oral cancer surgery.     

The influence of marital status on survival for patients aged 65 years and younger with oral cavity cancer

Objective

In Taiwan, the median age of diagnosis for oral cavity cancer is 51 year old, which is about 10 years earlier than that in Western countries. A recent study assessing the effect of marriage on outcomes for elderly oral cavity cancer patients (≥66 years old) showed that marriage was associated with better survival. However, little is known about the prognostic significance of marital status in oral cavity cancer patients aged 65 years and younger.

下咽癌共病食管癌的高危因素及预后分析

目的 探讨下咽癌共病同时性食管癌的高危因素及预后。 方法 2011年1月至2014年3月诊治的200例下咽癌患者作为研究对象,回顾性分析患者的一般资料、肿瘤信息和随访情况。先对可能影响下咽癌共病同时性食管癌的危险因素进行单因素分析,组间比较采用卡方检验,进一步将有统计学差异的因素纳入Logistic回归分析。生存率的分析采用Kaplan-Meier法。 结果 单因素分析发现,年龄(<55岁)、男性、重度吸烟史、重度饮酒史和肿瘤侵犯部位≥3个是下咽癌患者共病同时性食管癌的高危因素(P<0.05)。多因素分析结果显示,年龄(<55岁)、重度吸烟史、重度饮酒史和肿瘤侵犯部位≥3个是下咽癌患者共病同时性食管癌的独立危险因素(P<0.05)。200例下咽癌患者中位生存时间仅为37.5个月,5年生存率仅为36.7%。56例下咽癌共病同时性食管癌患者中位生存时间为24.8个月,低于下咽癌不伴同时性食管癌患者(P<0.05)。早期食管癌(0+Ⅰ期)患者的中位生存时间为29.2个月,明显高于进展期食管癌(Ⅱ+Ⅲ期)的15.8个月,差异有统计学意义(P<0.05)。 结论 下咽癌共病同时性食管癌患者的生存时间较低。年龄(<55岁)、重度吸烟史、重度饮酒史和肿瘤侵犯部位≥3个是下咽癌患者共病同时性食管癌的独立危险因素,临床上应该针对这些高危因素进行早期干预。     

Radical ablative surgery and radial forearm free flap (RFFF) reconstruction for patients with oral or oropharyngeal cancer: postoperative outcomes and oncologic and functional results

Conclusions. Radical ablative surgery and radial forearm free flap (RFFF) reconstruction provide promising oncologic and functional results in patients with oral or oropharyngeal cancer. Objectives. To assess the postoperative outcomes and the oncologic and functional results, with their main predictive factors, after radical ablative surgery and RFFF reconstruction for patients with oral or oropharyngeal cancer. Patients and methods. Between 2000 and 2006, we prospectively analyzed the postoperative, oncologic and functional outcomes of all previously untreated patients who underwent this type of surgery. Results. A total of 132 patients were enrolled in this study. There were three RFFF failures. The rate of surgical complications was 20%. The 5-year locoregional control and overall survival rates were 68% and 52%, respectively. Advanced age, high comorbidity index, elevated overall stage and tumoral involvement of the inner part of the cheek were correlated with a lower overall survival rate. A good functional result was obtained for oral diet, speech, mouth opening and aesthetic outcome in 87%, 80%, 86% and 88% of the patients, respectively. High comorbidity index, large flap surface, radiotherapy and tumoral involvement of the mobile tongue were significant predictors of poorer functional or aesthetic outcomes.     

The infrahyoid myocutaneous flap for reconstruction after oral cancer resection: A retrospective single-surgeon study

ObjectiveTo review our experience with infrahyoid myocutaneous flap in reconstruction after oral cancer resection.MethodsChart reviews were completed for all patients who underwent oral reconstruction with an infrahyoid myocutaneous flap by a single surgeon in the Department of Otolaryngology at Chonburi Cancer Hospital from 2011 to 2017. Characteristics of the patients and postoperative complications were analyzed.ResultsOf the 34 patients in the study, 10 (29.4%) developed partial flap loss and 1 (2.9%) developed total flap loss. All cases of partial flap loss resolved with conservative treatment. Apparent cancer involvement of a cervical lymph node was significantly associated with flap failure (odds ratio: 5.0, 95% CI: 1.03–24.28).ConclusionsThe infrahyoid myocutaneous flap is a fairly reliable reconstruction method. The flap should be performed with caution in cases with gross lymph node involvement.     

The profound oral cavity cancer burden in the United States Commonwealth of the Northern Mariana Islands: A global health opportunity

PurposeBetel nut consumption contributes to higher rates of oral cavity cancer throughout Micronesia. The purpose of this study is to review local surveys and cancer data to further characterize these issues in the Northern Mariana Islands (CNMI).MethodsTwo commonwealth-wide health inquiries were reviewed: The Non-Communicable Diseases Survey (NCDS), 2016 and The Youth Risk Behavior Survey (YRBS), 2013. Data pertaining to betel nut, tobacco and alcohol use was extracted. Relevant cancer data from the Commonwealth Healthcare Corporation (CHC) of Saipan and the Surveillance, Epidemiology, and End Results (SEER) databases was assessed.ResultsBetel nut chewing was reported by 43% of Asian Pacific Islander (API) adults, with 88% adding tobacco to the chew. Adults aged 20–30 had significantly higher rates of chewing relative to older groups (p < .0001). Tobacco smoking and alcohol use were reported by 25% and 23% of adults, respectively. Betel nut chewing was reported by 33% of high school students. From 2007 to 2016, oral cavity cancers contributed to 9% of all cancer diagnoses and 13% of cancer-related mortalities. SEER data supported oral cavity cancer diagnoses at younger ages in APIs.ConclusionThese results demonstrate concerning trends regarding alcohol, tobacco and betel nut use in the CNMI. Betel nut use is prevalent among APIs of nearly all ages, with the majority adding tobacco to their chew. The available data suggests a drastic oral cavity cancer burden in the CNMI. Efforts should be made to evaluate for effective means of primary and secondary prevention in API regions.     

Surgery alone for squamous cell carcinoma of the oral cavity: survival rates,recurrence patterns,and salvage treatment

Conclusion. Surgery alone may be a reliable and feasible treatment of choice in selected patients with squamous cell carcinoma (SCC) of the oral cavity, given the proper indications. Objective. To evaluate the results of treatment of oral cavity SCC patients with surgery alone in a single institution. Patients and methods. Between 1992 and 2004, 76 patients with previously untreated SCC of the oral cavity who had surgery alone without any other adjuvant treatment modalities were included in our study. Results. The 5-year overall rate, disease-specific survival rates, and locoregional control rate of all 76 patients were 69%, 83%, and 73%, respectively. A total of 16 patients (21%) presented with recurrences (8 with regional recurrences, 5 with local, 2 with locoregional, and 1 with distant metastasis). Four (6%) of the patients with primary T1 or T2 stage and one (50%) of those with T4 stage had recurrence at the primary site. The regional recurrence rate of patients with ≤N1 and ≥N2b was 10% (6 of 59) and 67% (2 of 3), respectively. Three of four patients who had recurrence at the primary site and attempted salvage treatment have been cured. However, only one of five patients with nodal recurrence and salvage treatment has recovered.
