Our purpose was to evaluate the use of the Harmonic scalpel in neck dissections.Material and methodsWe conducted a randomized prospective intervention study to compare the Harmonic scalpel (32 patients) with the conventional technique (31 patients).ResultsOperative time was lowered by 64 min (p < 0.001) and 7.5 min (p = 0.367); blood lost during surgery was lowered by 80.5 ml (p < 0.001) and 76.6 ml (p < 0.001); the length of time the drains were kept in place was lowered by 1.3 days (p < 0.001) and 1.5 days (p < 0.01); and the volume of drainage was lower by 228.7 ml (p < 0.001) and 187.6 ml (p < 0.01) in selective and comprehensive neck dissections respectively in patients treated with the Harmonic scalpel.ConclusionsThe Harmonic scalpel shortens operative time in selective dissections. It reduces blood loss during surgery; time drains are kept in place and the amount of drainage in comprehensive and selective neck dissections. 相似文献

The adequate treatment of the neck in early, clinically node-negative oral squamous cell carcinoma (OSCC) remains controversial. To assess whether elective supraomohyoid neck dissection is reasonable and efficient in early, locally circumscribed OSCC, the outcomes of treatment of 122 patients with an OSCC of clinical UICC stage I or II were retrospectively analysed in this study. Occult lymph node metastases were detected in 13.9% (17/122) of cases. They were more frequently found in T2 compared to T1 tumours (19.7% (14/71) vs. 5.9% (3/51), p = 0.03), age, gender and grading had no influence on the prevalence of occult lymph node metastases (all p-values > 0.05) in a multivariate logistic regression model. Subsequent multivariate survival analysis found that the presence of occult metastases was an independent predictor of reduced disease-free survival after 5 years (82.2% vs. 62.5%, p = 0.004, and 61.9% vs. 17.8%, p < 0.001, respectively). Elective supraomohyoid neck dissection detects occult metastases in early, node-negative OSCC, and patients with early OSCC exhibiting occult metastases should be considered as high risk patients, warranting additional therapeutic regimes. 相似文献

BackgroundTo assess the prognosis and morbidity between supraomohyoid neck dissection (SOND) and modified radical neck dissection (MRND) for oral squamous cell carcinoma (OSCC) in patients with a clinically node-negative neck (cN0).Patients and methodsThis prospective randomized study began in June 1999, and patient accrual concluded in May 2010. The cN0 neck was confirmed on clinical palpation by senior doctors. Ultimately, there were 322 patients recruited into the study.ResultsPatient demographics were well balanced between the two groups. There were 10 patients in the SOND group and 21 patients in the MRND group who developed nodal recurrence without associated local recurrence or distant metastasis. The 3-year neck control rate (NCR) rate was 92.6% for the SOND group and 87.5% for the MRND group (in favor of SOND, P = 0.108). There was no significant difference between the SOND group and the MRND group in the 3-year disease-specific survival (DSS) rate (79.0% vs. 76.9%, P = 0.659). Importantly, there were significantly fewer complications in the SOND group compared with the MRND group (13.0% vs. 21.9%, P = 0.040). The disease-free survivors in the SOND group also reported better pain relief (P = 0.013) and shoulder function (P < 0.001) than those in the MRND group one year after treatment.ConclusionsWe recommend SOND as a priority treatment for cN0 OSCC patients. 相似文献

Resection is the preferred treatment for oral squamous cell carcinoma, and pathological staging of the resected specimen is crucial. The role of molecular biology in the diagnosis of minimal residual disease has not been fully investigated and may improve staging. Multiple adjacent specimens were taken from the tumour, the invasive front, the surgical margin, and the lymph nodes of 20 specimens from patients with oral cancer. Bisulphite-treated DNA from these specimens was assayed quantitatively with pyrosequencing methylation assays (PMA) of CpG islands within the gene promoters of the p16 and CYGB genes. Results were recorded with histopathological results, and compared with clinical outcome. Biological and technical replicates confirmed the reliability of the techniques. PMA upgraded 13 of the 20 surgical margins, 6 of which subsequently had a recurrent tumour. Not all of these recurrences were predicted and the effects of adjuvant treatment make firm conclusions difficult. 相似文献

Unlike the levels of anatomical exploration, there is no consensus on the extent of lymph node dissection, or lymph node count (LNC), during selective neck dissection (SND). The aim of this study was to validate the prognostic impact of LNC on survival and to determine an optimal LNC cut-off value for SND. A retrospective investigation identified 78 patients with a diagnosis of oral squamous cell carcinoma (OSCC) who underwent SND (levels I–III or levels I–IV). LNC and clinicopathological variables were analyzed for any association with survival in Cox proportional hazards models. Based on the receiver operating characteristic curve, a cut-off value of 19 lymph nodes was found to predict overall survival (OS) (area under the curve 0.732, sensitivity 67.8%, specificity 75.0%; P = 0.026) and disease-specific survival (DSS) (area under the curve 0.762, sensitivity 68.1%, specificity 77.8%; P = 0.011). On Cox regression, LNC (≥19 vs. <19) was the only independent predictor of OS (hazard ratio 5.29, 95% confidence interval 1.39–20.05; P = 0.014) and DSS (hazard ratio 6.76, 95% confidence interval 1.40–32.77; P = 0.018). Similar results were obtained in the pathologically lymph node-negative subgroup (n = 66). Based on the study findings, SND should include 19 or more lymph nodes for a survival benefit. 相似文献

A clear bone margin is essential for complete resection of the bone-involved tumour, but the evaluation of hard tissue takes time and is impractical intraoperatively. Bone marrow assessment remains controversial. The aim of this study was to investigate the diagnostic value of intraoperative bone marrow assessment for bone margins. PubMed and Web of Science were searched for studies published between 1990 and 2017. A systematic review was conducted. After quality assessment, 10 articles with 11 cohorts and 404 patients were identified. Sensitivity, specificity, and other measures were pooled for meta-analysis; the estimates for intraoperative bone marrow assessment were as follows: sensitivity 0.82 (95% confidence interval (CI) 0.62–0.93), specificity 0.99 (95% CI 0.96–1.00), positive likelihood ratio 109.79 (95% CI 22.99–524.34), negative likelihood ratio 0.18 (95% CI 0.08–0.42), and diagnostic odds ratio 241.82 (95% CI 90.33–647.38). Furthermore, sensitivity and specificity at the summary operating point of the summary receiver operating characteristic curve were 0.82 and 0.99, respectively, and the area under the curve was 0.99. Intraoperative bone marrow assessment was investigated by meta-analysis and shown to have a high level of overall accuracy for the diagnosis of bone margins. 相似文献

The aim of this study was to investigate the impact of a prolonged treatment delay on survival in patients with primary oral squamous cell carcinoma. The investigators hypothesized that treatment delay affects survival, supposing a poor outcome in patients with prolonged treatment initiation. In addition, a critical treatment delay should be defined.Inclusion criteria were a histopathological diagnosis of primary squamous cell carcinoma of the oral cavity and a surgery-based treatment of the tumor. Patients with a history of previously diagnosed malignancies and patients with distant metastasis at the time of diagnosis were excluded from this protocol. Common clinical and histopathological data were assessed retrospectively. Treatment delay was analyzed for the interval between initial presentation and the date of surgery.A total of 484 patients could be included. Considering early-stage patients, the risk of death increases by 1.8% for each day that the treatment delay is prolonged if all other characteristics do not change (p = 0.0035). In patients with advanced disease, a prolonged treatment delay does not affect the risk of death (p = 0.9134). In terms of progression-free survival, treatment delay tends to be associated with a higher risk of recurrence in early-stage disease, but without being statistically significant (p = 0.0718). For patients with early-stage disease, a treatment delay of 20 days is critical regarding overall survival (p = 0.011). For patients with advanced-stage disease, no significant differences have been observed.As patients with early-stage oral squamous cell carcinoma profit from early treatment initiation, we suggest an acceptable maximum treatment delay of no more than 20 days in the surgical management of these patients. 相似文献

Due to the risk of occult cervical metastasis, elective neck dissection (END) is recommended in the management of patients with early oral cavity squamous cell carcinoma (OSCC) and a clinically node-negative (cN0) neck. This paper presents a systematic review and meta-analysis of studies that recorded isolated regional recurrence (RR) in the pathologically node-negative neck dissection (pN0) neck following END in order to quantify the failure rate. Pubmed and Ovid databases were systematically searched for relevant articles published between January 2009 and January 2019. Studies reporting RR following END in patients with OSCC who had no pathological evidence of lymph node metastasis were eligible for inclusion in this meta-analysis. In addition, a selection of large head and neck units were invited to submit unpublished data. Search criteria produced a list of 5448 papers, of which 18 studies met the inclusion criteria. Three institutions contributed unpublished data. This included a total of 4824 patients with median follow-up of 34 months (2.8 years). Eight datasets included patients staged T1-T4 with RR 17.3% (469/2711), 13 datasets included patients staged T1-T2 with RR 7.5% (158/2113). Overall across all 21 studies, isolated neck recurrence was identified in 627 cases giving a RR of 13.0% (627/4824) on meta-analysis. Understanding the therapeutic effectiveness of END provides context for evaluation of clinical management of the cN0 in these patients. A pathologically negative neck does not guarantee against future recurrence. 相似文献

Our purpose was to provide a pathological basis for preservation of the submandibular glands during neck dissection for oral squamous cell carcinoma (SCC) by investigating whether intraglandular lymph nodes exist in submandibular glands, and the modes of involvement of submandibular glands in oral SCC. We studied the records of 95 patients with oral SCC (other than that in the floor of the mouth) treated at our hospital from January 2017 to June 2018. The specimens of submandibular glands discarded after neck dissection were analysed, and serially sectioned. Sections 5 μm thick were obtained at 0.5 mm intervals and stained with haematoxylin and eosin for examination under light microscopy. A total of 116 specimens were obtained from the 95 patients, and about 5000 slides were evaluated. No intraglandular lymph nodes were detected in the submandibular glands. In the subgroup of patients whose primary tumours had extended into the floor of the mouth, four submandibular glands were involved by direct spread of the primary tumour. In the subgroup with metastases to level Ib lymph nodes, four submandibular glands were involved by extranodal extension from the metastatic nodes. No intraglandular lymph nodes or micrometastases were detected. We conclude that no intraglandular lymph nodes are present in submandibular glands, which may be involved by direct extension of the primary carcinoma or metastatic cervical lymph nodes with extranodal extension. Preservation of the submandibular glands during neck dissection seems to be feasible and safe in selected patients with oral SCC. 相似文献

The purpose of this retrospective study was to analyze the factors that had a significant effect on securing a successful surgical resection (surgical margin) in oral cancer surgery. One hundred forty-eight consecutive patients who underwent planned radical resection of oral squamous cell carcinoma (SCC) were analyzed. Successful resection was judged if pathological examination of the surgical specimen revealed a clear surgical margin (no SCC within 5 mm, n = 116), while an unsuccessful resection was judged if there was a close and involved surgical margin (SCC within 5 mm, n = 21; and SCC at margin, n = 11). Univariate analyses showed that gender, age, and T-classification had significant influence on successful surgical resection. The results of multivariate logistic regression analysis showed that age (odds ratio [OR] = 1.042, 95% CI = 1.001-1.084), T-classification (OR = 1.656, 95% CI = 1.060-2.587), and the presence of preoperative treatment (OR = 2.868, 95% CI = 1.047-7.85) had significant effects on successful surgical resection. The results of this study suggested that successful resection of oral SCC was difficult in patients with either older age or advanced (T4) tumor. It is also suggested that preoperative therapy had a positive effect on securing a pathologically clear surgical margin. 相似文献

There is a lack of consistency among published reports in the definition of what constitutes close resection margins (1-5mm) in the surgical treatment of oral and oropharyngeal squamous cell carcinoma (SCC). Our aim was to define what would constitute close resection margins in predicting local recurrence and disease-specific survival. The study comprised 192 previously untreated patients with oral and oropharyngeal SCC who were recruited at the Southern General Hospital, Glasgow, from 2001 to 2007 with a minimum follow-up of 2 years. Resection was the primary treatment and the surgical margins were recorded for all patients. Statistical analyses were aided by the Statistical Package for the Social Sciences, version 15.0, and MedCalc software. The status of the surgical margins was evaluated using a receiver operating characteristic (ROC) curve to define the cut-off point. Cox's proportional hazard model was used to establish predictive factors for local recurrence and disease-specific survival. Of 192 patients, 23 (12%) had involved margins (<1.0mm), 107 (56%) had close margins (1.0-2.0mm (16.1%); 2.1-3.0mm (12%); 3.1-4.0mm (10.4%); 4.1-5.0mm (17.2%), and 62 (32.3%) had clear margins (>5mm). No predictive cut-off point was found that related close surgical margins to local recurrence. However, there was a significant adverse association between surgical margins ≤1.6mm and disease-specific survival. In recommending postoperative adjuvant treatment for oral and oropharyngeal SCC, we suggest that surgical margins within 2mm should be considered as the cut-off. However, other clinical and pathological prognostic factors should also be taken into consideration when recommending further treatment. 相似文献

Controversy remains about management of the neck in squamous cell carcinoma (SCC) of the maxillary sinus and we know of no reports of the use of elective selective neck dissection for management in this site. We retrospectively reviewed 18 consecutive patients with SCC of the maxillary sinus who were managed by primary operation with curative intent. A total of 13 patients had an elective selective neck dissection, which was invaded in one case 8%. Four patients had regional metastases, two with positive nodal disease confirmed after elective selective neck dissection, and two who developed regional recurrence (both after elective selective neck dissections which were negative (pN0)). A review of other published articles in the English language showed no cases of elective selective neck dissections reported. The mean regional recurrence rate was 12% (range 0–26%) and total mean regional metastases rate 21% (range 5–36%). Elective selective neck dissection did not contribute to an improved rate of neck control with regional recurrence of 11% (2/18) compared with 12% in the review. There is no evidence in this report to indicate that elective selective neck dissections for maxillary sinus SCC will result in better disease control. Future research may indicate fewer radiotherapy fields for necks with pathologically clear nodes after elective selective neck dissection. 相似文献

口腔颌面-头颈鳞癌是发病率和死亡率较高的全球性疾病。临床常用的TNM分期不能对其遗传学特征和生物学特性作出正确的判断:肿瘤的分子特点对治疗方案选择、降低死亡率和提高生存率有一定帮助。特异基因表达谱的应用.能改善诊断方法.为个体化治疗提供基础;头颈鳞癌分子谱型的应用,可以对淋巴结转移和手术切缘作出正确的诊断.以便正确指导手术范围的确定。2000~2005年,约有40多篇有关头颈鳞癌基因表达谱的研究报道,本文就研究中发现有变化的基因进行综述和分析。结果表明,在肿瘤和非肿瘤之间,存在多个基因的变化。GO分类分析结果表明.这些基因涉及22种生理功能;进一步对这些变化基因进行基因组、蛋白组和功能的研究,将对揭示头颈鳞癌的分子病理学发生机制产生积极作用。 相似文献

肩胛舌骨上颈淋巴清扫术对控制口腔癌NO淋巴结转移的作用 总被引:7,自引:1,他引:6
目的:对施行根治性(RND)和肩胛舌骨上颈淋巴清扫术(SOHND)的NO期口腔癌患者进行回顾性比较研究,探讨肩胛舌骨上颈淋巴清扫术对控制口腔癌。NO淋巴结转移的作用。方法:对182例NO期口腔癌患者进行随访,并根据手术方式分为RND组和SOHND组,对颈淋巴转移、肿瘤复发及5年生存率进行统计分析。结果:本组资料颈淋巴结隐匿性转移率为27.5%,颈淋巴转移率随T分期升高而升高;口腔癌最易向颈深上淋巴结转移,其次是下颌下淋巴结和颈深中淋巴结,Ⅰ至Ⅲ平面转移占总转移率的92.0%;术后肿瘤复发率为17.0%,以局部和同侧颈部复发为主;RND对控制NO期口腔癌颈淋巴转移的有效率为95.2%,SOHND的有效率为94.8%;RND组5年生存率为67.6%,SOHND组为72.7%;两组间复发率及5年生存率无显著性差异。结论:肩胛舌骨上颈淋巴清扫术不仅能够评价NO期口腔癌颈淋巴结转移状况,而且能够有效控制发生隐匿转移的颈淋巴结。对于NO期口腔癌,选择性颈淋巴清扫术可采用肩胛舌骨上颈淋巴清扫术作为标准的治疗程序。 相似文献
