胃黏液腺癌的临床病理和CT特征

目的:探讨胃黏液腺癌的临床病理和CT特征。方法:回顾性分析507例行根治或姑息性切除术的胃癌病例的临床病理资料(20例黏液腺癌和487例非黏液腺癌)及术前的多层螺旋CT检查结果;对比分析20例黏液腺癌和38例非黏液腺癌的CT征象(CT轴位图像上肿瘤最大径、厚度、大体分型及强化方式)。结果:通过术前电镜活检,仅25.0%(5/20)的胃黏液腺癌得到确诊。20例黏液腺癌均为进展期胃癌,487例非黏液腺癌中早期胃癌占16.8%(82/487),但差异无统计学意义(P=0.056)。与非黏液腺癌相比,黏液腺癌肿瘤较大[(6.9±4.0)cm比(4.4±2.3)cm,P=0.011],淋巴结转移率较高(85.0%比60.6%,P=0.028),且Ⅱ～Ⅳ期病例较多(95.0%比72.3%,P=0.025);二者在CT轴位图像上肿瘤最大径(P=0.008)、厚度(P=0.001)、大体分型(P=0.037)和强化方式(P=0.000)间均存在显著差异。但黏液与非黏液腺癌在年龄、性别、肿瘤位置、远处转移和根治性切除率间均无差异。结论:胃黏液腺癌病例数少且多属进展期,通过内镜活检判断黏液腺癌的敏感度较低,而多层螺旋CT则有助于鉴别黏液和非黏液腺癌。     

分化型甲状腺癌的临床病理特征及手术范围

分化良好的甲状腺癌的手术切除范围,一直存在争议,原因有二:首先,此类型癌预后较好,侵袭性低,生存期很长,在我国尚缺少有说服力的术后10年乃至20年的随访资料;其次,分化良好的甲状腺乳头癌与滤泡癌,其病理类型较多,恶性程度相差甚远。一、乳头状癌的病理类型、恶性程度与手术范围1.高柱状细胞型乳头状癌:浸润范围广泛,常达到腺体外,乳头密集,被覆的癌细胞呈高柱状,为横径的3倍以上,胞浆粉染,核大,常偏于底部,明显异形,浸润性强,预后差。其切除范围应广泛。2.弥漫硬化型乳头状癌:癌组织常累及甲状腺一叶或两叶的一部乃至大部,呈浸润生长,伴广…     

大肠黏液腺癌临床病理特征的分析

目的深入分析大肠黏液腺癌独特的临床病理特征以指导临床诊断治疗,提高患者的预后。方法回顾性分析117例大肠黏液腺癌和424例大肠非黏液腺癌的临床和病理资料,并对各种临床和病理资料进行统计学分析。结果 (1)与非黏液腺癌相比,大肠黏液腺癌好发的年龄段偏低(平均年龄<50岁);(2)黏液腺癌好发于右半结肠,尤其是升结肠,但非黏液腺癌好发于左半结肠和直肠,且更多发于乙状结肠;(3)黏液腺癌瘤体相对较大(直径>5cm),分化程度更差;(4)黏液腺癌的分期相对较晚,更易向周围浸润生长,更易发生淋巴转移和远处转移;(5)蛋白nm23、p53在黏液腺癌中的阳性表达率更低。结论大肠黏液腺癌是一类预后较差的大肠癌,对大肠黏液腺癌应该采用更加积极全面的治疗方式。     

甲状腺结节和分化型甲状腺癌的规范化处理

甲状腺结节是指经影像学检查证实的,1个或数个可与周围正常甲状腺组织区分开的组织结构异常的团块,可由多种甲状腺疾病引起.甲状腺结节在临床上极为常见,流行病学资料显示,约10％的女性、2％的男性可涉及甲状腺结节.在随机人群中,19％～67％的女性和老年人存在可被超声发现的甲状腺结节.北美地区尸检显示有50％的受检者存在无症状的甲状腺结节[1-2].     

乳腺管状腺癌与浸润性导管癌临床病理特征和预后比较

目的 比较乳腺管状腺癌(tubular carcinoma,TC)与浸润性导管癌(invasive ductal carcinoma,IDC)的临床病理特征和预后.方法 回顾性分析1996-2009年乳腺癌手术治疗分期为Ⅰ/Ⅱ的41例TC患者和分期为Ⅰ/Ⅱ的2 568例IDC患者的临床资料,比较两者的临床病理特征和预后.结果 与IDC相比较,TC更容易用铝靶x线检测出(71% vs.22.9%,P<0.05),肿物较小,很少有淋巴结浸润(8.6% vs.22.9%,P<0.05).TC和IDC的复发率分别为7.9%和25.7%(P<0.05),TC的无病生存期显著高于IDC(P<0.05).结论 TC有着较好的临床病理特征和预后.此外,TC患者与正常人的预期寿命相似,所以辅助性化疗可能不适于作为TC的常规治疗.     

分化型甲状腺癌合并慢性甲状腺炎临床病理分析

目的：探讨分化型甲状腺癌合并慢性甲状腺炎（CLT）的临床病理特点。 方法：回顾性分析1998年—2008年收治的300例分化型甲状腺癌患者的临床病理资料。 结果：在300例分化型甲状腺癌患者中45例（15.0%）合并CLT。女性患者中合并CLT占据优势,合并CLT者肿瘤的大小明显小于未合并者（P=0.02）。 结论：分化型甲状腺癌合并CLT患者肿瘤的大小<单纯分化型甲状腺癌患者,提示前者的预后可能好于后者。

Ⅱ型和Ⅲ型食管胃结合部腺癌病理特征分析

目的分析Ⅱ、Ⅲ型食管胃结合部腺癌的病理特点。方法 2013-03—2015-03,对80例Ⅱ、Ⅲ型食管胃结合部腺癌患者行手术治疗,其中Ⅱ型58例,Ⅲ型22例。29例作全胃切除术,51例接受近端胃切除术,回顾性分析患者的病理资料。结果Ⅲ型食管胃结合部腺癌T分期为T3(77.3%)、T4分期(4.5%)均高于Ⅱ型,但比较差异无统计学意义(P0.05)。N分期Ⅱ型以N0型居多,Ⅲ型N2、N3分型所占比例分别为31.8%、9.1%,稍高于Ⅱ型,但差异无统计学意义(P0.05)。Ⅲ型TNM分期以Ⅲ型、Ⅳ型为主,稍高于Ⅱ型食管胃结合部腺癌,但差异无统计学意义(P0.05)。组织学分级Ⅲ型G3/4所占比例为59.1%,高于Ⅱ型,差异均无统计学意义(P0.05)。Ⅲ型食管胃结合部腺癌总淋巴结数目、阳性淋巴结数目及脉管癌栓阳性率均高于Ⅱ型,差异有统计学意义(P0.05)。结论较Ⅱ型食管胃结合部腺癌患者相比,Ⅲ型淋巴结转移率高,脉管癌栓阳性率高,且肿瘤分期高,生物学行为差。     

前列腺导管腺癌临床病理和诊治特点分析

Objective To discuss the pathological and clinical features, diagnosis and treatment of prostatic duct adenocareinoma. Methods The clinical data of nine cases of prostatic duct adeno-carcinoma were retrospectively analyzed, with the average age of 76 (59-106) years. Six cases were presented with dysuresia and/or nocturia, and two of them had the painless gross hematuria. Two pa-tients presented painless gross hematuria as the first symptom. One case was detected the elevated ser-um PSA in a routine healthy examination. Radical prostatectomy (RP) was performed in 1 case;RP and bilateral orchidectomy and external beam radiotherapy (EBRT) were performed in 1 case;5 cases underwent transurethral resection of the prostate (TURP) combined with photoselective vaporization of the prostate (PVP) by green laser and bilateral orchidectomy;1 case underwent TURP combined with PVP;1 case underwent bilateral orchidectomy combined with EBRT. Eight cases took flutamide for 3-45 months. All patients were followed-up according to the scheduled time. Results The op-erations were successfully performed in all 9 patients. The papillary or cauliflower-like tumors infiltra-ted colli culus seminalis and prostate duct nearby. The glands were coated with tall pseudostratified columnar cells. The nuclei were large, dark stained with more frequent mitoses. The positive rates of immunolabelling antibody PSA, AR, PAP were found to be 89%(8/9), 100%(5/5), 100%(5/5) re-spectively. The distribution of Gleason score was 6-7(3 cases), and≥8(6 cases), and a coexisting acinar carcinoma component was identified in 5 cases of the group. Nine cases had a mean follow up for 20(3-48) months. Five cases have developed biochemical recurrence, of whom 3 died of bone metas-tasis and multiple organ failure, and 1 developed lung and bone metastasis. Three cases remained alive without recurrence. The remaining 1 case survives during the follow-up survey for 6 months until now, without examinations due to the old age. Conclusions Duct adenocarcinoma of the prostate presents the low incidence and lacks of typical symptoms in the early stage. Diagnosis was confirmed mainly on the basis of pathology. The tumors tend to have a more advanced stage and a very short term survival rate. The treatment options and management are similar to that of high-grade adenocar-cinoma of the prostate;meanwhile, close follow-up survey should be performed.
