Endometrial carcinoma: Does the addition of intracavitary vault caesium to external beam therapy postoperatively result in improved control or increased morbidity?

A retrospective analysis of treatment for endometrial carcinoma is reported here. From 1987 to 1989, 138 patients were referred to the oncology department following total abdominal hysterectomy and bilateral salpingo-oophorectomy for endometrial cancer. Forty-seven patients were not prescribed postoperative radiotherapy; 31 had Stage I well differentiated adenocarcinoma with minimal myometrial invasion, while the remaining 16 patients were considered unfit for postoperative radiotherapy. There were no instances of local relapse amongst the 31 patients with minimal myometrial invasion.The remaining 91 patients all received external beam irradiation to the pelvis and, according to the preference of the individual therapist, 51 were prescribed additional intracavitary vault caesium-137. Patients receiving postoperative radiotherapy were analysed according to whether or not they received additional intracavitary vault caesium. The two groups were also analysed for incidence of vaginal vault recurrence and treatment related morbidity.In the group receiving additional intracavitary treatment more patients had Stage II or III disease (P<0.05), and had greater depth of myometrial invasion (P<0.05). Vaginal vault recurrence was not observed in patients receiving intracavitary therapy in addition to external beam therapy. Four patients (10%) receiving external beam therapy alone developed vaginal vault recurrence.The incidence of Kottmeier-Perez grade 2 or 3 bowel toxicity following treatment was significantly higher in those patients receiving combined treatment (18% vs. 2.5%; P<0.03). There was also a higher incidence of vaginal stenosis in the group receiving both external beam and intracavitary therapy (21% vs. 3%; P<0.05). There was only one instance of grade 2 bladder toxicity in the external beam and intracavitary treatment group and none in the external beam therapy alone group.In conclusion, postoperative radiotherapy for Stages I-III endometrial carcinoma was carried out in a non-randomized manner by two regimens; either external beam therapy alone or external beam therapy with additional intracavitary vaginal caesium. The combined therapy gave significantly better local control but resulted in significantly more late bowel and vaginal morbidity.     

子宫颈上皮不典型增生与宫颈癌细胞超微结构的观察比较

光镜和电镜观察慢性宫颈炎上皮不典型增生42例,宫颈癌21例,正常对照7例。上皮不典型增生之一是位于深部的储备细胞增生,细胞的核质比大,细胞器少,分化较低。鳞状上皮不典型增生细胞特点是核质比增大,核形不整,核膜内陷,细胞器增多,桥粒和张力原纤维减少。鳞癌细胞的核质比更大,核膜内褶深,细胞器更多,桥粒和张力原纤维很少或消失,分化低的癌细胞尤明显。粘液性腺癌腺上皮深部可见储备细胞转化的癌细胞。

子宫内膜增生性病变与子宫内膜癌的超声诊断价值

目的:探讨子宫内膜增生性病变与子宫内膜癌的超声鉴别诊断及内膜癌肌浸程度的估价.方法:采用术前B超、术后大体标本观察测量,对123例子宫内膜病变患者的声像图资料进行分析并与手术后病理结果对照.结果:①子宫内膜病变者子宫三径之和平均值均大于正常值;②58.6%的子宫内膜增生过长病变患者内膜形态以条形、梭形和正常形态回声;35%的Ⅱ期以上子宫内膜癌患者内膜回声以积液为主兼有其它图像类型;③大于50岁患者不同病理类型病变的子宫内膜平均厚度均超过其正常内膜厚度值,但无明显的规律性.小于50岁的患者内膜增厚主要以子宫内膜增生过长病变为主占48%;④通过超声测量子宫内膜厚度判断子宫内膜癌浅肌层和深肌层浸润符合率均为71.4%.结论:超声检查对判断子宫内膜病变病理类型有一定帮助,内膜厚度、内膜形态、回声特点、及内膜与肌层间的关系等,仅提示病变存在的可能性,要鉴别病变的良恶性、肌层浸润深度,须根据上述回声特点进行综合分析.     

高强度超声对犬前列腺组织损伤的实验研究

目的　探讨经尿道高强度超声 (transurethralhighintensityultrasound ,TUHIU)治疗良性前列腺增生症 (benignprostatichyperplasia ,BPH)的有效性和可行性。方法　对犬前列腺进行TUHIU辐照处理 ,辐照后不同时期处死动物以观察其急性、亚急性和慢性期大体及组织病理变化。同时观察辐照前后影像学变化。结果　TUHIU辐照前前列腺部尿道平均最大宽度为 0 66± 0 12 ( x±s)cm ,辐照 3周后前列腺部尿道平均最大宽度为 2 11± 1 0 7cm ,较辐照前显著增宽。辐照后可见靶区内尿道周围腺体发生凝固性坏死 ,3 0～ 60天后坏死组织脱落尿道呈囊腔状。光、电镜下均可见腺上皮及基质细胞发生均匀性凝固性坏死。辐照后经腹B超示前列腺内部出现液性暗区 ,前列腺呈囊性改变。辐照后即刻各犬均出现短暂性尿潴留、尿频、尿线变细 ,1月后恢复正常。结论　TUHIU可破坏前列腺组织 ,明显增加前列腺部尿道宽度。     

Vesicular pityriasis rosea: response to erythromycin treatment

Pityriasis rosea (PR) is a relatively common disease although its aetiology has not yet been identified. It occurs worldwide and there is no racial susceptibility factor. It usually affects teenagers and young adults between 10 and 35 years of age. Typical PR is much easier to diagnose than the rare atypical forms. We report a rare case of vesicular PR in a black woman who had vesicular lesions limited to her palms and soles in addition to regular typical lesions. We devised an efficient oral erythromycin treatment for this patient.     

手术治疗伴逼尿肌乏力的前列腺增生症

目的探讨BPH并有逼尿肌乏力(ACD)的病人是否手术等问题,为BPH并有逼尿肌乏力的病人治疗方法的选择提供依据.方法对尿动力学检查确认有ACD的15例BPH进行手术治疗.手术后复查尿流率.对所得数据进行自身配对t检验.结果术前和术后最大尿流率分别为(3.3±3.1)ml/s和(14.88±6.08)ml/s(P＜0.05).结论在前列腺摘除后,BPH伴有逼尿肌乏力的病人也能够产生有效排尿.故对确有膀胱出口梗阻(BOO)存在的BPH病人,即使有逼尿肌收缩乏力,也应积极手术.     

SA、F/TPSA及PSAD在前列腺癌诊断中的作用

目的 :探讨血清前列腺特异抗原 (PSA) ,血清总PSA及游离PSA比值 (F/TPSA)及前列腺特异性抗原密度(PSAD)在前列腺癌诊断中的作用。方法 :对 5 1例前列腺癌患者及 14 5例良性前列腺增生症患者PSA、F/TPSA及PSAD值的差异进行分析、比较。结果 :前列腺癌组血清PSA及PSAD高于良性前列腺增生组 ;而F/TPSA值低于良性前列腺增生组 ,差异均有显著性。结论 :PSA >4ng·ml-1作为筛选前列腺癌的临界值存在一定缺陷 ;当PSA <10ng·ml-1,F/T值有助于鉴别前列腺癌和良性前列腺增生 ;而PSAD对于筛选前列腺活检病例亦有一定价值。     

经尿道电切与气化切割和激光治疗前列腺增生症的疗效比较
