Treatment of a Recurrent Chest Wall Desmoid Tumor Using a CT-Guided Steroid Injection

We report on a 41-year-old woman with a chest wall desmoid tumour who was successfully treated with a computed tomography (CT)-guided steroid injection. She presented with a palpable mass in the right upper chest wall and was treated by surgical excision and postoperative radiation therapy due to recurrence of the mass at the surgical site. At 20 months after the second operation, a recurrent mass was again detected in the anterosuperior portion of the previous surgical site on CT. We performed a CT-guided steroid injection weekly for 4 weeks by applying a mixture of 3 mL of triamcinolone acetonide (40 mg/mL) and 3 mL of 1% Lidocaine, administering 4-6 mL of the mixture, to the lesion. Six months later, CT showed a marked decrease in the size of the mass.     

Tissue inhibitor of metalloproteinase‐1 levels in plasma from tumour arteries and veins of patients with rectal cancer

Objective. Tissue inhibitor of metalloproteinase‐1 (TIMP‐1) plays a major role in the regulation of tissue growth, including cancer growth. The TIMP‐1 protein can be determined in plasma, and increased plasma levels of TIMP‐1 are associated with a poor prognosis of colorectal cancer patients. The aim of the present study was to evaluate whether tumour tissue release of the TIMP‐1 protein contributes to the increased plasma levels of TIMP‐1 observed in patients with colorectal cancer. Material and methods. Preoperative blood samples from a peripheral vein and intraoperative blood samples from a tumour artery, a tumour vein and from a peripheral vein were drawn from 24 patients undergoing elective, intended curative surgery for primary rectal cancer. TIMP‐1 levels were determined concurrently in plasma from all samples using a validated ELISA method. Counts of white blood cells and platelets were also carried out. Results. No significant differences between plasma TIMP‐1 levels could be demonstrated in any compartment. In particular, there was no significant difference in TIMP‐1 levels in plasma from tumour arteries and tumour veins. However, there was a significant decrease in neutrophil cell counts from tumour arteries to tumour veins (p<0.001). Conclusions. The present results do not support the current hypothesis that tumour cells contribute substantially to increased plasma TIMP‐1 levels observed in patients with colorectal cancer.

肝间叶性错构瘤诊断与治疗(附2例报告并文献复习)

目的分析探讨肝间叶性错构瘤的临床特征与诊治方法。方法对收治的2例肝间叶性错构瘤患儿临床资料及诊治过程结合文献进行回顾分析。结果术前明确诊断相对困难,术中冷冻切片检查有助于鉴别肿瘤性质,但确诊仍需术后病理,手术治疗效果较为理想,预后多良好,偶有局部复发或恶变。结论肝间叶性错构瘤为多发于小儿的罕见肝脏良性肿瘤,血清AFP可显著升高,影像学检查有助于诊断,但需要有较丰富本专业和病理背景知识,手术治疗是目前最好的治疗方法,首选规则性肝切除术,且宜及早进行。     

Magnetic resonance cholangiography: comparison of two- and three-dimensional sequences for assessment of malignant biliary obstruction

The purpose was to retrospectively compare two-dimensional (2D) magnetic resonance cholangiography (MRC) including breath-hold single-shot rapid acquisition with relaxation enhancement (RARE) and multislice half-Fourier RARE versus navigator-triggered 3D-RARE MRC in the evaluation of biliary malignancy. MRC findings were evaluated in 31 patients with malignant biliary obstruction, including biliary malignancy, gallbladder carcinoma, and ampullary cancer. Two observers independently reviewed the images to assess the overall image quality, artifacts, ductal conspicuity, extent of disease, diagnostic confidence of tumor extent, and origin of tumor. The results were compared with surgical and histopathologic findings. Studies obtained with 3D-MRC were of significantly higher technical quality than those obtained with 2D-MRC. However, the accuracy between two sequences for classification of tumor showed no statistical significance. There was no significant difference between the Az values of 2D- and 3D-MRC for overall tumor extent in bilateral second order branch, intrapancreatic common bile duct (CBD) involvement (Az = 0.889, 0.881 for 2D and Az = 0.903, 0.864 for 3D). Nor was there a significant difference between two sequences in the assessment of the origin of tumor. Although 3D-MRC has superior image quality over 2D-MRC, 3D-MRC showed no statistically significant difference in accuracy compared with 2D-MRC for evaluating the extent of disease in malignant biliary obstructions.     

结直肠癌多层面CT仿真肠镜与纤维肠镜和手术病理的对比

目的：评价多层面CT仿真结肠镜（CT colonography，CTC）在结直肠癌诊断中的价值。方法：对59例结直肠癌患者术前行纤维肠镜与CTC检查，将CTC结果与纤维肠镜和手术病理对照。结果：1例由于肠道内残留物较多而无法准确显示癌灶，余58例中CTC发现结肠癌47例，直肠癌11例，其中4例为多发肠癌。CTC在显示肿瘤部位、大小、外形方面与手术结果高度相关。结论：CTC可准确显示结直肠病变，有助于结直肠癌的准确诊断。     

组织蛋白酶B与金属硫蛋白在结直肠癌中的表达及其临床意义

目的探讨组织蛋白酶B(CatB)和金属硫蛋白(MT)表达与结直肠癌淋巴结和肝转移的关系。方法采用免疫组化方法检测82例结直肠癌患者原发灶、正常肠黏膜、转移淋巴结和肝转移灶组织中CatB、MT的表达,对比分析CatB、MT表达与临床分期和病理类型的关系。结果结直肠癌原发灶、正常肠黏膜、转移淋巴结和肝转移灶中CatB表达阳性率分别为48.8%、20.7%、66.7%、59.1%,MT表达阳性率分别为53.7%、26.8%、71.4%、72.7%。结直肠癌原发灶、转移淋巴结和肝转移组织中CatB、MT表达阳性率均高于正常肠黏膜组织。转移淋巴结和肝转移灶中CatB、MT表达阳性率高于癌原发灶和无转移淋巴结组织。Dukes C、D期CatB、MT表达阳性率高于Dukes A、B期(χ2=11.0244、10.9338,P<0.01)。低分化腺癌和黏液腺癌CatB、MT表达阳性率高于高分化和中分化腺癌(χ2=10.9338、10.1148,P<0.01)。结论CatB、MT表达增强与结直肠癌的浸润和淋巴结、肝转移有关,可作为评价结直肠癌患者预后的重要指标。
