Thirty-four patients with surgically and pathologically proved pancreatic tumors and hyperplasia admitted during 1960-1978 are reported. Eighteen were male and 16 female with ages ranging from 21-62 yr. The clinical history before admission was 8 days to 14 yr, median 2.58 yr. Among them 26 were of adenoma, 3 of carcinoma and 5 of hyperplasia. All the malignancies showed metastasis. Seventeen out of the 29 tumors cases were located at the tail of pancreas. Hypoglycemia was usually induced by fasting,...

Eighteen were male and 16 female with ages ranging from 21-62 yr. The clinical history before admission was 8 days to 14 yr, median 2.58 yr. Among them 26 were of adenoma, 3 of carcinoma and 5 of hyperplasia. All the malignancies showed metastasis. Seventeen out of the 29 tumors cases were located at the tail of pancreas. Hypoglycemia was usually induced by fasting, fatigue, psychologic stress, menstruation, high fever and by alcohol. Misdiagnosis, stimulating tests and treatment are briefly discussed.

本文报道我院自1960~1978年间,经手术和病理证实的34例胰岛β细胞瘤,其中26例为胰岛β细咆腺瘤,3例为腺癌,5例为增生。文中就患者的临床表现特点,对本病的误诊,胰岛β细胞瘸的诊断以及本病中各种常用的功能(激发)试验的评价和治疗等问题作简要的探讨。

AbstractBetween 1979 and 1991, 48 cases of pancreaticparaffin-embedded specimens,ie 32 carcinomas and 16islet cell tumors, confirmed by operative and pathologi-cal examination, were studied by flow cytometric nu-clear DNA content measurements.10 specimens takenfrom the normal pancreatic tissue nearby the tumortransection margin and another 8 specimens in pancre-atitis were compared as controls. The results demon-strated that the aneuploid rate and DNA index in pan-creatic carcinoma was obviously higher than that ofnon-pancreatic tumor (P< 0.01) . In the field of pan-creatic carcinoma, the S-phase fraction was much high-er in aneuploid specimens (P<0.05) . Then the nucle-ar DNA content was a relatively independent factor toevaluate the cancerous biological behavier. The surgi-cal resectability of pancreatic tumors with diploid DNAwas significantly higher than aneuploid ones (P<0.05) , and the later carried a shorter survival timeproved by Kaplan-Meier survival analysis (P< 0.05) .Finally, the clinical significance of DNA content mea-surements in islet cell tumor was also discussed.

作者对本院1979~1991年手术和病理证实的32例胰腺癌、10例邻近癌的胰腺组织、8例胰腺炎以及16例胰岛细胞瘤石蜡包埋组织,用流式细胞仪(FCM)检测其细胞核DNA含量。结果发现:胰腺癌的异倍体率及DNA指数明显高于胰腺非肿瘤病变者(P<0.01);DNA异倍体胰腺癌的S期比例亦明显高于二倍体胰腺癌(P<0.05);胰腺癌细胞核DNA含量的变化是一个相对独立的反映胰腺癌生物学行为的指标。DNA二倍体胰腺癌患者的手术可切除率明显高于异倍体肿瘤患者(P<0.05)。采用Kaplan-Meier生存分析法显示,DNA异倍体胰腺癌较二倍体者生存时间短,预后差(P<0.05%)。

Ten cases of pseudotumorous pancreatitis were reported. Their clinical and imaging manifestations, operative and pathologic findings were analysed with literature review. It was difficult to differentiate this entity from pancreatic tumors be fore being diagnosed histologically. The authors are of the opinion that the diagnosis can be confirmed by percutaneous needle biopsy and follow-up for young patients without jaundice, and laparotomy must be considered for old or jaundiced patients.

本文报告了10例假肿瘤性胰腺炎(PseudotumorousPancreatitis),结合文献报道分析了该病的临床表现、影像学征象、手术探查结果和病理表现。笔者认为:本病在组织学论断前难以和胰腺肿瘤鉴别,对年龄较轻且无黄疸的患者可作经皮穿刺活俭及随诊明确诊断,对年龄较大或有黄疸者应考虑手术探查。
