  • VERTICAL TRAPEZIUS MYOCUTANEOUS FLAP FOR REPAIRING SOFT TISSUE DEFECT AFTER HEAD AND NECK TUMOR RESECTION

    Objective To introduce the experience of the cl inical appl ication of vertical trapezius myocutaneous flap in repairing soft tissue defects after head and neck tumor resection. Methods Between June 2008 and February 2010, 12 cases of soft tissue defect caused by head and neck tumor resection were repaired with vertical trapezius myocutaneous flap.There were 9 males and 3 females with an age range from 32 to 76 years (median, 54 years). Twelve cases including 2 cases of basal cell carcinoma of orbital skin, 2 cases of squamous cell carcinoma of the parotid gland, 2 cases of submandibular gland mal ignant mixed tumor, 2 cases of metastatic lymph nodes of nasopharyngea carcinoma after radiotherapy, 1 case of squamous cell carcinoma of tongue, and 3 cases of squamous cell carcinoma of occipital skin, and all were classified as TNM stages T3 or T4. The area of soft tissue defect ranged from 13 cm × 6 cm to 25 cm × 13 cm. The vertical trapezius myocutaneous flap ranged from 14 cm × 7 cm to 26 cm × 14 cm and was transfered to repair defect tissue in the homolateral wounds after tumor resection and neck dissection homochronously. The donor sites were sutured directly. Results All incisions healed primarily without infection. Eleven flaps survived except 1 flap with edge necrosis, which was cured after dressing change. Subcutaneous hematocele and effusion occurred in 2 cases on the back after tube was removed at 7 days postoperatively, and they were cured by sucted and pressured dressing. Eleven patients were followed up 1-3 years (mean, 2 years). Nine cases had no tumor recurrence and the flaps had statisfactory appearance; the abduction function of shoulder joint were normal. One case of orbit basal cell carcinoma occurred 3 months after operation and 1 case of nasopharyngeal carcinoma died of brain metastasis 12 months after operation. Conclusion It is an easy and simple therapy to repair head and neck soft tissue defect using the vertical trapezius myocutaneous flap, which can meet the needs of repairing tissue defect of head and neck.

  • Non-Conventional Fractionated Radiotherapy for Head and Neck Cancer: A Systematic Review

    Objective To evaluate the efficacy and side effect of non-conventional fractionated radiotherapy for head and neck cancer.Methods Trials were identified by searching CENTRAL, MEDLINE, EMBASE, Chinese Biological Medicine Database (CBMdisc) and Chinese VIP Database. We handresearched the data from 10 kinds of important Chinese journals. Two reviewers assessed and extracted the studies. The following primary outcomes were assessed: complete relief (CR), overall survival (OS), acute side effect and late side effect. Results Twenty-three trials involving 8 411 patients were included. Thirteen trials were of good quality, and the rest were of poor quality. Meta-analysis of these trials showed that: (1) non-conventional fractionated radiotherapy vs conventional fractionated radiotherapy: ① Only S-HART and CAIR resulted in higher CR, RR=1.21 (95%CI 1.02 to 1.44), 3.31 (95%CI 1.16 to 9.42), respectively; ② Only HRT could improve 2-year OS (RR=1.32, 95%CI 1.13 to 1.54), but this difference wasn’t found in 5-year follow up; ③ Most of the non-conventional fractionated radiotherapy could increase acute side effects, but not the late ones; (2) non-conventional fractionated radiotherapy combined with concurrent chemotherapy vs non-conventional fractionated radiotherapy: ① Only C-HRT resulted in higher CR (RR=1.58, 95%CI 1.18 to 2.11); ② Higher 2-year OS could be gained when combined with chemotherapy (RR=1.35, 95%CI 1.18 to 1.54), and only C-HRT resulted in higher 5-year OS (RR=1.57, 95%CI 1.19 to 2.07). ③ Acute and late side effects of radiotherapy would not increase when combined with chemotherapy. Conclusion It can not be concluded that non-conventional fractionated radiotherapy can improve the CR and OS of head and neck cancer, for a small number of patients, but it will get effect when combined with concurrent chemotherapy, and would not increase acute or late side effects. The effects of HRT and C-HRT should be cared specially.

  • The Application of 18F-FDG PET/CT in Head and Neck Neoplasms

    目的:探讨18F-FDG PET/CT在头颈部肿瘤的临床应用价值。方法:58例头颈部恶性肿瘤病例,男37例,女21例,年龄21~78岁。其中:牙龈癌3例,上颌窦癌2例,舌癌2例,腮腺癌1例,鼻咽癌24例,喉癌8例,甲状腺癌4例,原发灶不明的颈部淋巴结转移瘤14例。使用18F-FDG行全身PET/CT扫描,依据PET图像、CT图像和PET/CT融合图像及标准化摄取值(SUV)进行综合评价。结果:29例放疗患者中的11例拟行根治性放疗的患者,有4例改行姑息性放疗,8例重新勾画了放疗靶区及调整了放疗剂量,3例改行其它治疗;15例进行了放疗后的疗效评估;14例原发灶不明的颈部淋巴结转移瘤8例找到了原发灶。结论:PET/CT可以对头颈部恶性肿瘤进行准确的临床分期,精确勾画放疗的生物靶区,准确而快捷地确定肿瘤复发的位置与侵犯范围,在颈部不明原发灶转移瘤的应用中具有简便、快捷、无创和灵敏等临床特点。

  • 容积旋转调强放射治疗技术在头颈部肿瘤的应用

    容积旋转调强放射治疗(VMAT)技术作为一种新型的放射治疗(放疗)技术,通过照射过程中机架连续旋转,连续改变剂量率、机架位置和多叶准直器叶片位置等,实现不同射野方向上的射束强度调整。其最大优势在于能达到与传统调强放疗技术相似或更好剂量分布的同时,大大提高了治疗效率。但作为新兴技术,完整的VMAT执行方案还有待开发,现有的临床数据相当有限。头颈部肿瘤因其复杂的解剖结构,对放疗计划质量要求甚高,该文旨在对VMAT在头颈部肿瘤的应用作一综述,以期为VMAT在头颈部肿瘤的临床实施提供循证依据。

  • Head and Neck Tumor Segmentation Based on Augmented Gradient Level Set Method

    To realize the accurate positioning and quantitative volume measurement of tumor in head and neck tumor CT images, we proposed a level set method based on augmented gradient. With the introduction of gradient information in the edge indicator function, our proposed level set model is adaptive to different intensity variation, and achieves accurate tumor segmentation. The segmentation result has been used to calculate tumor volume. In large volume tumor segmentation, the proposed level set method can reduce manual intervention and enhance the segmentation accuracy. Tumor volume calculation results are close to the gold standard. From the experiment results, the augmented gradient based level set method has achieved accurate head and neck tumor segmentation. It can provide useful information to computer aided diagnosis.
