PURPOSE A retrospective study was made of the role of apoptosis in determining radiotherapy outcome in 39 adenocarcinoma of the cervix. A comparison was also made of the detection of apoptosis by morphology and the TdT dUtp nick end-labeling (TUNEL) assay. METHODS AND MATERIALS The level of apoptosis was assessed in paraffin-embedded sections by cell(More)
A relationship between hypoxia and apoptosis has been identified in vitro and in experimental tumours. The aim of this study was to investigate the relationship between apoptosis, hypoxia and the change in oxygenation during radiotherapy in human squamous cell carcinoma of the cervix. Forty-two patients with locally advanced disease underwent pretreatment(More)
Recently, attention has focused on the potential of oncogenes, tumour suppressor genes, and assessment of cell proliferation as biological response indicators in human cancer. In this study, immunocytochemical analysis was used to evaluate the usefulness of Ki67, epidermal growth factor receptor (EGFr), and the protein products of c-Myc and Bcl-2 as(More)
PURPOSE To investigate the relationship between radiation-induced apoptosis and clonogenic cell kill in 9 cervical cancer cell lines. METHODS AND MATERIALS Cells were irradiated with 0, 2, 8, and 30 Gy. The level of apoptosis was evaluated using flow cytometry (Annexin-V binding), light microscropy (morphology), gel electrophoresis (DNA ladder formation),(More)
