支气管动脉灌注化疗治疗晚期原发性肺癌近期疗效影响因素分析

目的探讨经支气管动脉灌注化疗(BAI)治疗晚期肺癌近期疗效的影响因素。方法回顾性分析1990年3月至2006年6月间胸部X线片复查资料相对完整的82例经BAI治疗的原发性晚期肺癌的近期疗效。结果完全有效(CR)10例(12.2%)、部分有效(PR)32例(39.0%)、轻微有效(MR)23例(28.0%)、稳定(SD)15例(18.3%)、进展(PD)2例(2.4%)。单因素方差分析结果显示,半月时肿瘤缩小率(TDR1/2month)(χ2=25.92,P<0.01)、BAI次数(TBAI)(χ2=17.70,P<0.01)、肿瘤大小(Tsize)(χ2=14.21,P<0.01)和肿瘤血供丰富程度(χ2=6.59,P<0.01)对近期疗效的影响具有统计学意义。对年龄、病理类型等12项协变量进行二项分类Logistic回归分析,采用向后删除法经10步二次迭代,得到Logistic回归方程:P(1)=1/[1 e-(-8.953 2.656TDR1/2month 1.382TBAI 1.230Tsize)],方程对BAI近期疗效有效与无效的预测正确率分别为85.7%和70.0%。结论第1次BAI后半月时的肿瘤缩小率、BAI治疗次数和肿瘤的大小是影响BAI近期疗效的因素。

THE CHARACTERISTICS OF OVARIAN SEROUS TUMORS OF BORDERLINE MALIGNANCY

During 1948-1976, 363 cases of ovarian serous tumor were encountered in the hospital. Among them, 58 cases were pathologically compatible with the criteria of this tumor of borderline ma- lignancy proposed by the WHO classification. The purp8se of this paper is threefold: 1. To study the c!inical behavior and mode of de- velopment of pathologically documented bordcr- line malignant serous ovarian tumors. 2. To compare the difference between benign, border- line malignant and malignant serous tumors. 3. To assess the value of making such a "borderline malignant" subgroup.     

GREATER OMENTUM-CUTANEOUS AXIAL FLAP A METHOD TO CREATE TRANSFERABLE SKIN FLAP

In view of the fact that the blood vessels of the donor area for a free flap must be of an "axial pattern", that not all axial pattern flaps which are supplied by a direct cutaneous artery, are suitable for clincial applications, and that the availability of these flaps is greatly limited in patients with severe burns or multiple injuries, we have deviced a kind of new flap, the greater omentum-cutaneous axial flap, to replace the conventional free flap in plastic and reconstruc- tive surgery. Preliminary clinical application of this type of flap in 3 cases proved successful.     

RELATIONSHIP BETWEEN CORNEAL DELLEN AND TEARFILM BREAKUP TIME

The BUT of 51 strabismus patients were measured before and after operation. The average pre-op BUT was 28.75 seconds(10.96"-91.80"). The post-op BUT in all operated eyes were reduced significantly, no matter what procedures had been performed and whether dellen appeared or not(P<0.01). The BUT in the group complicated dellen reduced from 23.22"(pre-op) to 8.61"(post-op). The incidence of dellen was 22.54% in this study. The incidence of dellen after rectus resection procedure(47.75%) was much higher than that after rectus recession(5.13%)(P<0.01). This study showed that dellen was closelyre related to the BUT and occurred more often in the eyes on which resection procedure was performed. It is considered that excessive lacrimation and elevation of the bulbar conjunctiva near the limbus may disturb the stability of the precornea tearfilm and cause the tearfilm break up earlier. Local corneal dehydration and dellen formation may be caused by reduced BUT. The incidence of dellen after operation may be higher if the cornea was carefully observed.     

EXPERIENCE IN THE SURGICAL TREATMENT OF CARCINOMA OF THE ESOPHAGUS

Much progress has bcen made iu the surgi- cal treatment of esophageal carcinoma in China as well asl. many other countries in'the past ZO 3rears. With reasonahly early diagnosis, it is withir:ttllo ability of thoracic surgeons today to achieve a resectability rate of 75-85%, an opera- tive mortality rate bclow 5% and a 5-year sur- vival rate of 30-40%" With careful selection of patients for operation and proper use of radia_ tion and other adjunct therapy. oven more encouraging results are rjossible. Efforts for further improvement may be directed toward early diagnosis and refiuemcnt in operative technics, such as the use of microsurgery in re construction of the esophagus and further deve- lopmcnt Olr instrumcnfis for esophagogastrjc anastonwsis.
