ABSTRACT
Breast cancer has overtaken lung cancer as the most common malignancy in women. Although the early diagnostic rate has continuously improved, recurrence and metastasis remain a problem to be solved. Therefore, scientists should search for effective prognostic markers for breast cancer patients and adopt individualized programs for different patients. Studies have shown that cancer prognosis, to a certain extent, is related to the nutrition inflammation index. Preoperative prognostic nutritional index (PNI) and controlled nutritional status (CONUT) are indicators that comprehensively reflect the nutritional level and inflammatory state of patients, respectively. Different from other cancers, the incidence of breast cancer is related to nutritional status, and an extremely high or low score is not conducive to the prognosis of breast cancer patients. This paper reviews the research progress of PNI and CONUT in breast cancer.
ABSTRACT
Lung cancer is a common malignant tumor in the world and NSCLC accounts for the majority. Although the overall survival rate of patients with NSCLC is improving through surgery, chemotherapy, radiotherapy, targeted therapy and immunotherapy, the prognosis of some patients is still poor. Inflammatory response plays an important role in the occurrence, progress and metastasis of tumors. Therefore, the whole blood cell count associated with inflammatory response will be an effective index to predict the prognosis of NSCLC. The systemic immune-inflammatory index (SII), composed of neutrophils, lymphocytes and platelet systems, can fully reflect the systemic inflammation and immune status of the host, and can be combined with other inflammatory indexes such as C-reactive protein/albumin value (CAR), advanced lung cancer inflammatory index (ALI) and prognostic nutritional index (PNI). It can increase the predictive efficacy of NSCLC patieats' prognosis. In addition, SII has the advantages of low cost, simple operation and convenient acquisition, and is easy to be used in clinic. This paper reviews the research progress of the relation between SII and the prognosis of NSCLC.
ABSTRACT
Fibroblast growth factor receptor ( FGFR) is one of the molecules involved in tumor formation , and plays an impor-tant role in cell proliferation , angiogenesis and migration .In this article, we review the role of FGFR signal pathway in breast cancer , the correlation with the risk and prognosis , the function of FGFRs as potential therapeutic targets for breast cancer and discuss various treatment strategies of targeted FGFR 1 in clinical trials .
ABSTRACT
Purpose:To study the RNA interference-mediated inhibition of survivin gene on the proliferation of human breast cancer SKBr-3 cells. Methods:SKBr-3 cells were transfected with a pSUPER-S1 vector plasmid that expressed survivin-targeted small interfering RNA, and the mRNA and protein levels of survivin gene were measured with RT-PCR and indirect immunofluorescence, respectively. The proliferation of transfected SKBr-3 cells was investigated through colony forming assay and MTT assay. The cell cycle phases were determined by flow cytometry(FCM). Results:The mRNA and protein levels of survivin declined markedly in pSUPER-S1-transfected SKBr-3 cells. And the colony forming rate of those cells(38?16.70)% was significantly lower than that of the control cells(90.3?4.04)%.The growth of the pSUPER-S1-transfected cells was decelerated and the cell cycle was mainly blocked at G_(1) phase(74.03?8.91)%. Conclusions:survivin gene silencing by RNA interference contributed to a distinctive inhibition of the proliferation of human breast cancer SKBr-3 cells in vitro.
