Recent studies have reported that hyper-methylation in the promoter region of miRNAs could silence the expression of tumor suppressive miRNAs and might play significant roles in the process of tumor development. However, the potential mechanisms regarding how methylation of miRNA CpG Island could regulate cancer cell chemo-resistance have not yet been studied. Using microarray and BSP (Bisulfat...
AIM To define the best sequence of radiotherapy and chemotherapy for inoperable stage III non-small cell lung (NSCL) tumours. MATERIALS AND METHODS A systematic review was performed on the clinical results of radiotherapy, combined or not with chemotherapy, for inoperable NSCL cancer stage III. The mean median survival time (MST) and mean overall survival (OS) percentages were derived for rad...
Acquired chemo-resistance is one of the key causal factors in cancer death. Emerging evidences suggest that miRNA and epithelial-mesenchymal transition play critical roles in the chemo-resistance in cancers. Here, we showed the association of paclitaxel-resistance with miR-375 over-expression and epithelial-mesenchymal transition inducement in cervical cancer. Using different cervical cancer ce...
BACKGROUND/AIMS MicroRNA-218 (miR-218) is down-regulated in many malignancies that have been implicated in the regulation of diverse processes in cancer cells. However, the involvement of miR-218 in chemo-sensitivity to cisplatin and the precise mechanism of this action remained unknown in bladder cancer. METHODS qRT-PCR was used to detect miR-218 and its target Glut1 expression in bladder ca...
Non-small cell lung cancer (NSCLC) is one of the leading causes of death in all lung cancer patients due to its metastatic spread. Even though cisplatin treatment after surgical resection of the primary tumor has been established as a standard chemotherapy for residual disease including metastatic spread, NSCLC often acquires a resistance against chemotherapy, and metastatic disease is often ob...
Radio- and chemo-resistance represent major obstacles in the therapy of non-small-cell lung cancer (NSCLC) and the underlying molecular mechanisms are not known. In the present study, during induction of radio- or chemo-resistance in NSCLC cells, dynamic analyses revealed that decreased expression of let-7 induced by irradiation or cisplatin resulted in increased expression of its target gene L...
The impact of squamous cell carcinoma antigen (SCC) in the follow-up of patients with advanced cervical cancer treated with (chemo-) radiotherapy in primary and postoperative settings was evaluated. One hundred and forty-one patients with histologically proven squamous cell carcinoma of the uterine cervix were treated at the department of radiotherapy and radiation oncology. The serum level of ...
BACKGROUND The results of the recently published large European randomised study in rectal cancer (European Organisation for Research and Treatment of Cancer 22921 trial) do not support current guidelines recommending postoperative chemotherapy for patients who have previously undergone preoperative radiochemotherapy or radiotherapy [radio(chemo)therapy]. To evaluate this discrepancy further, a...
PURPOSE The extra benefit of adding chemotherapy to effective endocrine therapy (ET) has not been clearly or consistently identified in patients older than 70 years with estrogen receptor (ER) positive and node positive breast cancer. The aim of this study was to evaluate the efficacy of adjuvant ET vs. chemotherapy plus endocrine therapies (Chemo/ET) in such patients. METHODS In this retrosp...
BACKGROUND Anthracycline drugs for cancer therapy often cause functional myocardial impairment even in relatively low doses. We investigated the left ventricular function in asymptomatic anthracycline-treated children by automatic border detection (ABD) to assess its clinical usefulness for unmasking latent anthracycline-induced myocardial damage. METHODS AND RESULTS Thirty-four children (0.7...
