早期胃癌的诊治(附15例临床分析)

目的：总结15例早期胃癌临床特点，诊治经验，探讨治疗新进展。方法：对15例早期胃癌诊治进行回顾性总结。结果：早期误诊率达66．7％，15例手术，术后存活5年以上13例（86．7％）。结论：早期胃癌缺乏特异症状，早期误诊率高，内镜下平坦型胃癌最易误诊，作认为D2术应为根治EGC的标准术式，内镜下粘膜切除术（EMR），保留迷走神经胃段切除术有利于保护患术后生存质量。     

原癌基因蛋白质C-erbB-2在乳腺良恶性病变中表达的意义

目的:检测原癌基因蛋白质C-erbB-2在乳腺良恶性病变中的表达及意义.方法:对111例乳腺良恶性病变的石蜡切片标本进行免疫组织化学染色.结果:乳腺良恶性病变中乳腺导管内乳头状瘤病的C-erbB-2阳性率为31.3%,与乳腺纤维腺病和纤维腺瘤比较差异有显著性(P<0.01),乳腺癌C-erbB-2的阳性率为74.3%,与良性病变比较差异有显著性(P<0.01);乳腺癌C-erbB-2表达与肿瘤大小和组织学分级呈正比(P<0.05),与激素受体(ER、PR)水平及5年生存期呈反比(P<0.05),与淋巴结是否转移无关.结论:C-erbB-2表达的乳腺导管内乳头状瘤病容易癌变,C-erbB-2过度表达的乳腺癌组织分化差、生存期短、预后不好.C-erbB-2 可作为判定乳腺导管内乳头状瘤病早期癌变及乳腺癌预后的有效指标.     

Relationship with God and the Quality of Life of Prostate Cancer Survivors

This study explored the role of relationship with God with respect to the quality of life of men with prostate cancer. Thirty-four men with prostate cancer completed questionnaires on demographic and illness factors, aspects of relationship with God (e.g., God image), nonreligious resources (e.g., optimism) and physical, social and emotion functioning. Results showed that relationship with God was a significant factor in the prediction of role, emotional and social functioning for these men after controlling for age, reported severity of treatment reactions and nonreligious resources. Notably, different aspects of relationship with God (e.g., causal attribution) evidenced different associations with functioning and the nonreligious resource of perceived health control. Such results suggest that relationship with God may function in a complex manner as a resource in coping with prostate cancer. Longitudinal research is needed to clarify the role of religious/spiritual resources in the short- and long-term quality of life of men with prostate cancer.     

Evaluation of an aortic stent graft for use in surgery on esophageal cancer involving the thoracic aorta

Objective: The purpose of this experimental study was to investigate whether aortic stent grafting can be applied to the treatment of an esophageal cancer involving the thoracic aorta. Methods: The canine thoracic aorta was partially resected without aorta being clamped after emplacement of an endovascular stent graft. Study I; The aortic whole layer of 1 cm in length and 1/4 of the circumference was resected and was covered by a free fascia patch of the abdominal rectal muscle immediately after stent graft placement. Study II; The aortic adventitia and the outer half of the media of the same size was resected on day 3, 7,14, 21, and on day 28, after the stent graft placement. The resected portion was covered by the free fascia patch in half experimental dogs, and was uncovered in the others. Study III; The aortic adventitia and the outer half of the media of 1 cm in length and 1/2 of the circumference was resected and was uncovered on day 7 after stent graft placement. Histological examinations were performed on day 28 and at one year after aortic resection. Results: The aortic wall could be resected in all cases with no complication, except in resection of 1/2 the circumference where the aorta had become narrow. There was no difference in healing of the resected portion of the aorta between with and without fascia covering. Conclusion: An aortic endovascular stent graft could be applied to surgery for an esophageal cancer involving the aorta.     

食管癌颈部吻合术中前壁单层吻合术的应用

目的　探讨食管癌颈部吻合术中前壁单层吻合的临床应用价值 ,并与同期荷包状食管胃吻合法 (前壁双层吻合法 )相比较。方法　对 32 1例食管癌行根治性切除及食管胃颈部吻合术 ,其中前壁双层吻合 16 1例 ,前壁单层吻合16 0例。结果　双层吻合术中 ,吻合口瘘 5例 (3.13% ) ,随访 137例 ,吻合口直径 <0 .5 cm者占 5例 (3.5 % ) ,0 .5 - 1cm者70例 (5 0 .9% ) ,1cm以上者 6 2例 (4 5 .6 % ) ,单层吻合术中 ,吻合口瘘 7例 (4 .38% ) ,随访 131例 ,吻合口直径 <0 .5 cm者无 1例发生 ,0 .5 - 1cm者 5 3例 (4 0 .8% ) ,>1cm以上者 78例 (5 9.2 % )。结论　食管癌颈部吻合术中 ,前壁单层吻合能减少吻合口狭窄 ,改善术后病人的生活质量 ,而吻合口瘘发生率无明显增加。     

非小细胞肺癌微转移灶的检测及临床意义

非小细胞肺癌(NSCLC)是常见的恶性肿瘤，治疗效果不佳，有许多术中证实淋巴结阴性的患者仍在术后出现复发，这可能是由于存在常规病理手段无法发现的微转移病灶所导致。近年来，免疫组化和分子生物学方法已应用于外周血、骨髓及肿瘤附近淋巴结中微转移灶的检测，但是检测微转移灶的指标选择及临床意义目前仍有争论。作者讨论常见的检测NSCLC微转移的方法及检测结果的临床意义。

87例肺癌患者核素骨显像结果分析

目的：通过对87例肺癌患者放射性核素全身骨显像结果进行分析，探讨肺癌骨转移的特点和规律。方法：回顾性分析了经临床病理证实的87例肺癌患者的全身骨显像表现。结果：肺癌骨转移率为63．2％，发生骨转移最常见的部位为肋骨，其次为脊椎骨、盆骨、四肢骨、肩胛骨、颅骨和胸锁骨。在不同病理类型的肺癌中，腺癌和鳞癌较其它类型更易发生骨转移。结论：肺癌骨转移比较常见，所以肺癌患者应常规作全身核素骨扫描，以帮助临床制订正确的治疗方案。
