Metastatic tumors in the hand from adenocarcinoma of the colon

Osseous metastases to the hand are rare. The primary site is usually in the lung, breast, or kidney. Two cases of metastatic tumor in the hand from adenocarcinoma of the colon are reported herein. These patients presented two and four years after initial resections of colonic carcinomas. General aspects of diagnosis, etiology, and management are discussed.     

Association of Fusobacterium nucleatum infection with colorectal cancer in Chinese patients

AIM: To investigate Fusobacterium nucleatum(F. nucleatum) abundance in colorectal cancer(CRC) tissues and its association with CRC invasiveness in Chinese patients.METHODS: The resected cancer and adjacent normal tissues(10 cm beyond cancer margins) from 101 consecutive patients with CRC were collected. Fluorescent quantitative polymerase chain reaction(FQ-PCR) was applied to detect F. nucleatum in CRC and normal tissues. The difference of F. nucleatum abundance between cancer and normal tissues and the relationship of F. nucleatum abundance with clinical variables were evaluated. Fluorescence in situ hybridization(FISH) analysis was performed on 22 CRC tissues with the highest F. nucleatum abundance by FQ-PCR testing to confirm FQ-PCR results.RESULTS: The median abundance of F. nucleatum in CRC tissues [0.242(0.178-0.276)] was significantly higher than that in normal controls [0.050(0.023-0.067)](P 0.001). F. nucleatum was over-represented in 88/101(87.1%) CRC samples. The abundance of F. nucleatum determined by 2~(-ΔCT) was significantly greater in tumor samples [0.242(0.178, 0.276)] than in normal controls [0.050(0.023, 0.067)](P 0.001). The frequency of patients with lymph node metastases was higher in the over-abundance group [52/88(59.1%)] than in the under-abundance group [0/13(0%)](P 0.005). No significant association of F. nucleatum with other clinico-pathological variables was observed(P 0.05). FISH analysis also found more F. nucleatum in CRC than in normal tissues(median number 6, 25~(th) 3, 75~(th) 10 vs 2, 25~(th) 1, 75~(th) 5)(P 0.01).CONCLUSION: F. nucleatum was enriched in CRC tissues and associated with CRC development and metastasis.     

Addressing hepatic metastases in ovarian cancer: Recent advances in treatment algorithms and the need for a multidisciplinary approach

The lifetime risk for ovarian cancer incidence is 1.39% and the lifetime risk of death is 1.04%. Most ovarian cancer patients are diagnosed at advanced stages(Ⅲ, Ⅳ) because there were no specific symptoms or existing screening tests. Liver metastases have been found in up to 50% of patients dying of advanced ovarian cancer. Recent studies indicate the need for a multidisciplinary approach from initial diagnosis to oncologic surgery and chemotherapy treatment, mandating the involvement of gynecologic oncologists, surgical oncologist, medical oncologists, hepatobiliary surgeons, and interventional radiologists.     

3．0T磁共振灌注加权成像在脑胶质瘤诊断中的价值

目的探讨3.0T磁共振灌注加权成像在脑胶质瘤术前分级及与脑单发转移瘤鉴别诊断中的价值。方法对经病理证实的脑胶质瘤患者（低级别15例,高级别17例）和单发转移瘤患者14例的MR灌注加权成像资料进行回顾性分析,测算肿瘤实质区与瘤周水肿区的相对脑血容量（rCBV）值,并进行统计学分析。结果 （1）在肿瘤实质区,低级别胶质瘤的rCBV值为（1.982±0.436）低于高级别胶质瘤rCBV值（5.574±1.124）,在瘤周水肿区,低级别胶质瘤的rCBV值为（0.796±0.215）低于高级别胶质瘤的rCBV值（1.497±0.192）,差异均有统计学意义（P〈0.05）;（2）在肿瘤实质区,单发转移瘤的rCBV值为（3.087±1.017）低于高级别胶质瘤的rCBV值（5.574±1.124）,在瘤周水肿区,单发转移瘤的rCBV值为（0.356±0.145）低于高级别胶质瘤的rCBV值（1.497±0.192）,差异均有统计学意义（P〈0.05）。结论灌注加权成像作为一种无创性的评价手段,可以提高脑胶质瘤术前分级的准确性,并在与单发转移瘤鉴别诊断方面有一定临床价值。     

脊柱转移瘤的MRI诊断

目的：探讨脊柱转移瘤的MRI表现及诊断价值。材料与方法：回顾性分析52例经临床和病理证实的脊柱转移瘤的MRI表现。结果：（1）52例共累及209节椎体,167节附件,“跳跃征”发生率占71．7％。（2）病灶T1WI均表现为低信号,T2WI因其类型不同而分为高（24．4％）,低（30．1％）和混杂（45．5％）信号,“晕征”出现率占26．9％。（3）椎旁肿块、椎管受累和椎间隙狭窄发生率分别为57．1％、60．7％和64．3％。结论：MRI对脊柱转移瘤的诊断有重要的价值。

胃癌淋巴结大小与转移的探讨

目的　本文通过胃癌淋巴结病理与CT对照 ,讨论根据淋巴结大小 (以 >10mm为标准 )判断淋巴结转移的可靠性。方法　 2 4例胃癌切除和D1或D2 淋巴结清除以及术前CT检查 ,分别记录淋巴结直径大小、数量和转移阳性率。结果　 2 4例胃癌手术摘取淋巴结 3 95个 ,病理证实 12 3个 (3 1% )淋巴结转移阳性。10mm以下的淋巴结占 76% ,其中 5 6%的淋巴结转移阳性 ,1～ 5mm和 6～ 9mm淋巴结转移率分别为 8%和 46% ;10mm或以上淋巴结转移阳性率分别为 5 4%和 68%。CT检出淋巴结 174个 ,病理证实 71个 (4 1% )淋巴结转移阳性。小于 10mm淋巴结占 3 8% ,1～ 5mm和 6～ 9mm淋巴结转移率分别为 17%和 3 1% ;10mm以上淋巴结转移阳性 5 0 %～ 76%。结论　胃癌小淋巴结转移率也较高 ,CT影像单纯依据淋巴结大小判断淋巴结转移是不可靠的。
