Intraoperative radiotherapy of upper abdominal tumours

Thirty patients with malignant tumours in the upper abdomen underwent surgery and intraoperalive radiation (IORT), using electron beam, to: the surgical bed, residual or unresected tumour. The technical aspects and results of this treatment are described. Renal, adrenal, bile duct and gastrointestinal tumours were treated. along with several other lesions. The surgical procedure consisted in 10 cases simply of exposure of the tumour for IORT and in 20 the tumour was resected. The TORT dose ranged from 10 to: 20 Gv. In 13 patients, external beam radiation was also given to: residual tumour or to: areas of high risk for recurrence. Chemotherapy was given to: 10 patients. Tolerance to: the combined treatment was acceptable; with few complications related to: IORT.The median follow-up and survival time 23 months (range 4-more than 70 months). Local tumour control rate (or tumour stabilisation) is 90%. Distant metastases developed in 19 patients (63%). The actuarial survival rate for the group projected at 70 months (maximum follow-up) is 37%. IORT in useful in the management of tumours arising in the upper abdominal organs, for palliation surgery or when resectability of the tumour is in doubt. Indications for IORT include patients with uncommon tumours of the upper abdomen who are not be candidates for standardised cancer treatment.Presented at the European Congress of Radiology, Vienna, September 15–20,1991     

肿瘤高危人群的流式细胞术、内窥镜和病理检查的对比研究

本文对上消化道肿瘤高发区经初筛的１２０例高危人群粘膜组织做了流式细胞ＤＮＡ含量、内窥镜和组织病理学检查的对比研究。其结果显示的肿瘤阳性检出率分别为２７．５％、６．７％和１４．０％。对内窥镜诊断为不同胃疾病患者的流式细胞术分析发现，流式细胞术阳性检出率，胃癌组为７５．０％，萎缩性胃炎组为２８．３％，浅表性胃炎组为７．１％，正常粘膜组为０％。ＤＩ值均值，炎症组（萎缩性胃炎和浅表性胃炎）患者与正常对照组接近，而癌组则明显升高。增殖指数和Ｓ期细胞比例，从正常对照→浅表性胃炎→萎缩性胃炎→胃癌组，呈递增变化，而且各组间有显著差异。     

Ultrasonographic findings in gastric cancer: in vitro and in vivo studies

Ultrasonography was performed in 45 cases of gastric cancer. Specimens from all 45 cases of gastric cancer were subjects to ultrasonographic study by the water immersion method for comparison with histology. In 32 of these 45 cases in vivo ultrasonographic evaluation was performed prospectively. The overall accuracy rates for the diagnosis of the depth of cancerous invasion were almost 80% in both in vitro and in vivo studies. In vivo ultrasonographic findings agreed well with those from the specimen studies. Ultrasonography was considered to be useful in the diagnosis of gastric malignancies.     

氚掺入法检测低分化鼻咽癌亚株的放射敏感性差异及放射增敏

目的 探讨人低分化鼻咽癌亚株之间的放射敏感性差异及对其放射增敏。方法 采用氚掺入法检测其亚株对射线敏感的差别；通过细胞周期同步化对其放射抵抗亚株S1增敏。结果氚掺入法结果表明放射后1-15受抑制程度大（P〈0．05）；TNF仅可以使细胞周期同步化达到了放射增敏，对放射抵抗亚株增敏后缩小了亚株间的放射敏感性差距。结论 低分化鼻咽癌亚株存在着放射敏感性差异；对其放射抵抗亚株增敏后差异不显著。     

荷瘤鼠乳腺癌组织的飞秒双光子荧光诊断

目的：检测荷瘤鼠乳腺癌组织的双光子荧光光谱。方法：乳腺癌荷瘤鼠腹腔注射血卟啉（HpD)。以飞秒激光照射小鼠的癌组织部位及周围正常组织部位。观察HpD双光子荧光光谱。结果：小鼠的癌组织部位可观察到外源性HpD双光子荧光光谱，而正常组织部位未观察到明显的双光子荧光光谱。结论：结论：飞秒激光外源性血卟啉双光子荧光诊断可作为癌症诊断的新方法。     

原发鼻腔透明细胞癌3例及文献复习

目的:分析原发鼻腔部透明细癌胞的起源,病理,临床特点及治疗.方法:分析本院1992年9月～2003年9月收治的3例原鼻腔透明细胞癌患者资料,均有病理证实,中位年龄为60岁;主要症状为鼻塞逐渐加重,流涕,间断性流血涕,咽部不适等.3例均行放疗,1例为肿物切除术后放疗,1例初治放疗,1例肿物切除术后放疗后骨转移行化疗,采用6MV-X线治疗2例,8MV-X线治疗1例,DT 40Gy.结果:2例健在,1例死于呼吸,循环衰竭.结论:原发鼻腔部透明细胞癌较罕见,以局部浸润生长为主,发展迅速,可有淋巴道、血液转移,手术加放疗、化疗有效.     

Leukemia clusters around nuclear facilities in Britain

He bas been retained for the defense by British Nuclear Fuelsplc in two suits in which leukemia and non-Hodgkin's lymphoma have been alleged to result from radiation exposures due to the operation of the nuclear reprocessing plant at Sellafield. This paper has been sent to the senior authors of the papers reporting clusters of leukemia or other malignancy in the vicinity of nuclear facilities in Britain and their comments invited. Subject to considerations of space and CCC style, these comments will be published as submited.     

痛力克对癌症疼痛镇痛效果的临床观察

应用印度ＬＵＰＩＮ公司提供的痛力克（酮酷酸氨丁三醇 ）对中重度癌症疼痛３０例进行镇痛效果的临床观察，有效率９３％，平均显效时间９ｍｉｎ，均数缓解时间５．１ｈ，并用哌替啶做了同期交叉自身镇痛对比研究，结果表明：两药的镇痛效果相似（Ｐ＞０．０５），但痛力克的不良反应发生率明显低于哌替啶。
