ABSTRACT
[Objective]To explore the feasibility and safety of percutaneous kyphoplasty(PKP) and percutaneous vertebroplasty(PVP) treating osteolytic lesions of high thoracic vertebra with metastasis by one side extrapedicular approach,and to assess the clinical result of minimally invasive technique. [Methods]In March 2008,one patient(male,59 years old) with T1~3 vertebral metastases of lung cancer diagnozed 8 months ago was selected.The symptoms included extremely severe pain in upper thoracic spine and left should.The analgesic effect was limited for more than 6 months.There was no operative option.Domestic PKP and PVP tool systems were used in local anaesthesia.Under fluoroscopic guidance,T2 and T3 vertebral augmentation were separately completed by single side extrapedicular approach PKP and PVP.Clinical results were followed up and observed.[Results]The procedure was performed smoothly.T3 and T2 vertebrae were differently treated by PKP and PVP.T1 received no treatment because of patient`s intolerance.The operative time of T3 vertebral PKP was 57 minutes.The volume of injected bone cement was 1.9ml.The operative time of T2 vertebral PVP was 49 minutes.The volume of injected bone cement was 1.5ml.Extravertebral leakage of the polymethylmethacrylate(PMMA) into the paravertebral itssue was found without clinical symptom,because osteolysis occurred in the left pedicle of T2 vertebra.There was no other complication.The patient was discharged 5 days after operation.The preoperative,2 days and 3 months postoperative follow-up VAS scores were 10,3 and 6.The patient's markedly pain could be controlled by analgesia.[Conclusion]One side approach percutaneous kyphoplasty is a safe and effective technique for treatment of high thoracic vertebral metastasis with markedly relief of pain.
ABSTRACT
Objective:To observe the expression of estrogen receptor alpha(ER?) and beta(ER?) in human tongue cancer cell line Tca8113 and its highly metastatic cell line Tb. Metheds:Immunocytochemistry, RT-PCR methods were used to observe the expression of ERs in the in vitro cultured human tongue cancer Tca8113 and Tb cells.Results:ER? and ER? mRNA were expressed in both cell lines,and the expression of ER? in Tb cells was stronger than that in Tca8113 cells, the expression of ER? was the same in the two cell lines. The ratio of ER? to ER? was higher in Tb cells than that in Tca8113 cells.Conclusion:The overexpression of ER? and ER?/ER? ratio may be associated with the higher potential of metastasis of Tb cells.
ABSTRACT
Objective:To obtain some effective objective markers used to predict the early liver metastasis of colorectal tumor,the relationship of liver metastasis of colorectal tumor with associate detection three markers such as CK20mRNA、CD44V6 and PCNA was studied. Methods:The expression of CK20mRNA in portal venous blood from 30 colorectal cancer patients was detected by fluorescent quarto RT-PCR,and the results of CD44V6 and PCNA in colorectal cancer tissue were determined by means of immunohistochemistry, and then compared with control groups through statistics analysis. Results:The rate of positive expression of CK20mRNA in colorectal cancer patients' portal venous blood was obviously superior to the level of benign pathological changes controls(P
ABSTRACT
The cutaneous metastasis of pancreatic carcinoma by this technique is rarely reported in the literature. A 67-year-old woman was evaluated for left-sided abdominal pain and a palpable abdominal mass. Abdominal CT confirmed the presence of a solid mass involving the pancreas. Ultrasonically guided percutaneous aspiration biopsy was performed. About six month later, the patient was readmitted with a tender tumor mass at the site of the previous aspiration biopsy. Physical examination disclosed a 4 × 4 cm sized firm, tender tumor mass on the abdomen. Histopathological findings of the tumor mass are consistent with metasta tic lesions from a pancreatic carcinoma. We report a case that suggests cutaneous metastsis of pancreatic carcinoma by fine needle aspiration biopsy.
