Objective To investigate the diagnosis and treatment of hepatic metastasis from gastrointestinal stromal turnor(GIST).Methods The clinical data of 16 patients with GIST who had been admitted to our hospitalfrom December 1993 to May 2007 were retrospectively analyzed.Results Of all patients,14 underwent radical resection and 2 underwent palliative operation.Two patients with palliative operation and 3 with radical resection were administered with imatinib postoperatively. All patients were followed up for 3-161 months,and GIST metastasis and invasion was observed in 8 of the 14 patients who received radical resection.Of the 7 patients with hepatic metastasis.3 were treated with hepatic artery chemoembolization,1 was administered with imatinib,2 received reoperation and 1 did not receive any treatment. Reoperation was carried out on 1 patient who had abdominal wall metastasis.The 1-and 3-year survival rates of the 16 patients were 92%and 74%,respectively.Conclusions The recurrence rate of GIST after hepatectomy is high.Complete surgical resection is the best curative treatment for hepatic metastasis from GIST and GIST recurrence.The combination of surgical resection and imatinib administration may help to improve the prognosis of patients with hepatic metastasis from GIST.

Objective To study the correlations between the genetic polymorphism of brain-derived neurotrophic factor (BDNF) and the postpartum depression (PPD) in cesarean section parturient. Methods Three hundred and sixty parturients, who underwent cesarean section under spinal anesthesia from Feb. 2014 to Feb. 2015 in Third Xiangya Hospital of Central South University or Hunan Maternal and Child Health Hospital, were selected as subjects. The general information of parturients was recorded and Edinburgh Postnatal Depression Scale (EPDS) was used to evaluate the depression condition of parturients at the prenatal 1 day and the 42th day postpartum, and with a cut-off point of 12/13 for identifying PPD. The genotypes of BDNF gene locus G712A, rs56164415, rs11030100, rs11030101 and rs6265 were measured by Sequenom? Mass Array SNP. Finally, the correlations of PPD to different genotypes and general information of parturients were statistically analyzed. Results The incidence of PPD among the selected subjects was 7.2%. Pregnancy mental stress, poor pregnancy mood, perinatal elevated monocyte count, prenatal depression mood and BDNF gene locus rs6265 mutation all could affect the incidence of PPD in cesarean section parturients (P<0.05). No statistically significant difference existed between BDNF gene G712A, rs11030101, rs11030100 and rs56164415 locus mutation and PPD (P>0.05), and their haploid forms were not related to PPD also. Conclusion BDNF rs6265CC genotype, pregnancy mental stress, poor pregnancy mood, perinatal elevated monocyte count and prenatal depression mood are the risk factors for postpartum depression.

The reported incidence of synchronous multiple primary cancer (SMPC) is rare, and it is even less common to observe synchronous solid tumor with a hematological malignancy. We report five cases of solid tumor presented synchronously with hematological malignancy, all observed within a 2 year period at the oncology department of a university hospital in Shanghai, China. These individual cases included lung adenocarcinoma with chronic myelogenous leukemia, colon cancer with solitary plasmocytoma, gastric adenocarcinoma with diffuse large B cell non-Hodgkin's lymphoma, lung adenocarcinoma with multiple myeloma, and colon cancer with diffuse large B cell non-Hodgkin's lymphoma. It is challenging to therapeutically control the biological behavior of concurrent multiple primary tumors, and there is no standard treatment for such rare conditions. In this paper we discuss these five cases of SMPC and their treatments.

OBJECTIVETo investigate the expression of NOEY2 gene in breast cancer tissue and its relation to clinicopathological and other molecular parameters.

METHODSThe mRNA expression of NOEY2 gene was monitored in benign and malignant breast lesions by RT-PCR and in situ hybridization (ISH) with transcripted antisense RNA probes. The protein expression of estrogen receptor (ER), Ki67, p27 and p21(WAF1) in the 60 breast cancer lesions was detected by immunohistochemical method.

RESULTSAll 6 benign lesions, and 13 (72.2%) of the 18 breast cancers were NOEY2 positive by RT-PCR. By ISH, positive NOEY2 was obtained in all 10 benign lesions but only in 31 (51.7%) of the 60 breast cancer lesions. The difference was statistically significant (P = 0.025). NOEY2 positive rate tended to decrease with the increase of histological grade. However, NOEY2 expression was negatively correlated with the status of axillary lymph nodes. The positive NOEY2 rate was 75% in those without lymph node metastasis but only 26.7% in those with metastasis (P < 0.001). No correlation with other clinicopathological parameters including ER, Ki67, p27 or p21(WAF1) were found.

CONCLUSIONNOEY2 gene may be related with the pathogenesis of breast cancer. A link between NOEY2 loss expression and the spreading mechanism of breast cancer may possibly exist.
