Adjuvant radiotherapy in carcinomas of the uterine cervix: the prognostic value of hemoglobin levels

Anemia has been associated with a poorer treatment response and reduced survival in women undergoing primary radiotherapy (RT) or radiochemotherapy for advanced cervical carcinoma. This study aimed to determine the influence of anemia on outcome in patients with cervical carcinoma undergoing adjuvant RT. Medical records were reviewed for 183 cervical cancer patients who had received adjuvant RT because of risk factors after radical surgery (n= 109) or inadequate primary surgery (simple hysterectomy; n= 74). Kaplan-Meier and Cox regression analyses were used to study hemoglobin levels before and during adjuvant RT in relation to recurrence-free and overall survival. Hemoglobin values > or =11 g/dL were considered normal, while those <11 g/dL indicated anemia. Hemoglobin levels before RT influenced significantly overall survival and recurrence-free survival across the whole group (overall survival--log rank(all patients)= 7.5; df = 1; P= 0.006). However, subgroup analysis showed that the observed difference was mainly due to the group of women who had undergone inadequate primary surgery (overall survival--log rank(inadequate surgery)= 10.8; df = 1; P= 0.001). Multifactorial regression analyses comparing hemoglobin before RT with grading and tumor stage confirmed the prognostic value of hemoglobin values. Maintaining normal hemoglobin values before and during adjuvant RT seems to be important, especially in patients who have had inappropriate simple hysterectomy, which may resemble a therapeutic situation.     

神经移植重建面神经在腮腺癌根治术中的应用

目的：探讨腮腺深叶癌切除面神经后，即刻功能性修复的临床效果。方法：对1984年1月至2005年10月间收治的11例腮腺癌患者，术中采用将肿瘤连同腮腺及面神经切除，同时行颈丛神经移植重建面神经的治疗方法。结果：术后面神经功能均完全恢复，所有患者术后6个月复诊，见患者静态时面部对称，动态时口角轻度偏斜，术后一年两侧面部完全对称，睁、闭眼及提口角功能基本恢复正常。结论：腮腺癌根治术中采用颈丛神经移植能有效地恢复面神经的功能，既达到肿瘤切除的彻底性，又符合功能外科的发展要求，是一种比较理想的手术方法。     

颈清患者保留及重建肩功能的研究进展

<正>1906年,Crile等人针对头颈部恶性肿瘤易发生颈淋巴结转移的情况提出了根治性颈淋巴清扫术(radical neck dissection,RND),这一术式在后来的很多年里,挽救了许多患者的生命。但RND损伤了副神经和颈部的一些重要的解剖结构,常导致患者斜方肌瘫痪萎缩,出现翼状肩胛、垂肩、肩周疼痛麻木、手臂活动受限、功能障碍等并发症,     

Tendon Graft—Ulna Fixation in Distal Radio-Ulnar Joint Stabilisation; Biomechanical Comparison of Three Graft-Bone Fixation Methods

A common distal radio-ulnar joint (DRUJ) stabilisation procedure uses a tendon graft running from the lip of the radial sigmoid notch to the ulnar fovea and through a bony tunnel to the ulnar shaft, before being wrapped round the distal ulna and sutured to itself. Such graft fixation can be challenging and requires a considerable tendon length. The graft length could be reduced by fixing the graft to the ulna using a bone anchor or interference screw. The aim of this study was to compare the strength of three distal ulna graft fixation methods (tendon wrapping and suturing, bone anchor and interference screw). Four human cadaveric ulnae were used. A tendon strip was run through a tunnel in the distal ulna and secured by: (1) wrapping round the shaft and suturing it to itself, (2) a bone anchor and (3) an interference screw in the bone tunnel. Load to failure was determined using a custom-made apparatus and an Instron machine. Maximum failure load was highest for the bone anchor fixation (99.3 ± 23.7 N) followed by the suturing (96.2 ± 12.1 N), and the interference screw fixation (46.9 ± 5.6 N). There was no significant difference between the tendon suturing and bone anchor methods, but the tendon suturing was statistically significantly higher compared to the interference screw (P = 0.028). In performing anatomical stabilisation of the DRUJ fixation of the tendon graft to the distal ulna with a bone anchor provides the most secure fixation. This may make the stabilisation technique less demanding and require a smaller tendon graft.     

上胸椎骨折手术治疗方法的探讨

目的 探讨上胸椎骨折的特点及治疗。方法 15例病人按AO分型，A型2例、B型10例、C型3例。均经后路切开复位、脊髓减压、长节段内固定、取髂骨植骨融合术治疗。结果 随访18-24个月，后路长节段固定随访时无一例失败，完全瘫的患者9例中有1例神经功能改善I级．不完全瘫的5例均有Ⅲ级改善，1例无神经损伤。结论 上胸椎骨折损伤严重，后路长节段固定技术是一种合理的有效治疗方法。
