肝针吸良、恶性细胞核内AgNORs图像分析的定量研究

应用真彩色图像分析技术对肝针吸细胞中的２０例肝癌及５例增生肝细胞核内ＡｇＮＯＲｓ进行了定量研究。结果显示，肝针吸肝癌细胞核内ＡｇＮＯＲｓ的平均面积、平均积分光密度、颗粒直径及平均颗粒数均明显高于增生肝细胞（Ｐ＜００１）；ＡｇＮＯＲｓ图像定量分析可为肝针吸癌细胞和增生肝细胞的鉴别诊断提供一种新的定量指标；ＡｇＮＯＲｓ在形态、数量及分布上的不同特征也可作为鉴别两者的重要依据。     

Dose-Volume Histograms for bladder and rectum

: A careful examination of the foundation upon which the concept of the Dose-Volume Histogram (DVH) is built, and the implications of this set of parameters on the clinical application and interpretation of the DVH concept has not been conducted since the introduction of DVHs as a tool for the quantitative evaluation of treatment plans. The purpose of the work presented herein is to illustrate problems with current methods of implementing and interpreting DVHs when applied to hollow anatomic structures such as the bladder and rectum.

: A typical treatment plan for external beam irradiation of a patient with prostate cancer was chosen to provide a data set from which DVH curves for both the bladder and rectum were calculated. The two organs share the property of being shells with contents that are of no clinical importance. DVHs for both organs were computed using a solid model and using a shell model. Typical treatment plans for prostate cancer were used to generate DVH curves for both models. The Normal Tissue Complication Probability (NTCP) for these organs is discussed in this context.

: For an eight-field conformal treatment plan of the prostate, a bladder DVH curve generated using the shell model is higher than the corresponding curve generated using the solid model. The shell model also has a higher NTCP. A six-field conformal treatment plan slo results in a higher DVH curve for the shell model. A treatment plan consisting of bilateral 120-degree arcs, results in a higher DVH curve for the shell model, as well as a higher NTCP.

: The DVH concept currently used in evaluation of treatment plans is problematic because current practices of defining exactly what constitutes “bladder” and “rectum.” Commonly used methods of tracing the bladder and rectum imply use of a solid structure model for DVHs. In reality, these organs are shells and the critical structure associated with NTCP is obviously and indisputably the shell, as opposed to its contents. Treatment planning algorithms for DVH computation should thus be modified to utilize the shell model for these organs.     

HBV 感染、家族肝癌史与 ABO 血型在低发区原发性肝癌的关系

本文研究了高、低发区５１０例ＰＨＣＨＢＶ感染、家族肝癌史及与ＡＢＯ血型的关系，结果表明：１肝癌低发区与高发区一样，合并ＨＢＶ感染的ＰＨＣ患者达８０．７４％，远多于无ＨＢＶ感染者；男性多于女性；有家族肝癌史的ＰＨＣ患者占４０．００％，且合并ＨＢＶ感染的ＰＨＣ有家族肝癌史者显著多于ＨＢＶ阴性组（Ｐ＜０．０５）；２低发区ＰＨＣ中，有家族肝癌史的Ａ型血者显著多于相应对照组（Ｐ＜０．０５）。提示我国肝癌低发区ＰＨＣ发生的最重要外因亦为ＨＢＶ感染，遗传易感性则是其内因；而有ＨＢＶ感染或有家族肝癌史者是ＰＨＣ的高危人群，且后者中的Ａ型血者更为易患，对这一人群需加强监测，警惕ＰＨＣ的发生。     

手术径路对贲门癌远期生存的影响(附353例随访结果分析)

了解手术径路对贲门癌术后远期生存率的影响。方法：对本院353例贲门癌分左胸、上腹及胸腹联合切口三种径路进行手术，术后逐年随访，了解手术径路对贲门癌术后远期生存的影响。结果：全组总1、3、5、10年生存率分别为86．1％、56．7％、49．9％、20．9％。左胸组、上腹组及胸腹联合切口组5年生存率分别为37．6％，46．25％，57．6％。三组间各TNM分期的5年生存率经用加权卡方检验差异并无显著性（P＞0．05）。而肿瘤的浸润深度与淋巴结的转移状况对其预后有显著影响（P＜0．01）。
