Neither chemotherapy nor radiotherapy alone is adequate to treat both bulky local disease and the almost universal distant micrometastases of small cell lung cancer (SCLC). Despite improved overall and 2-year survival rates associated with combining the two treatment modalities, however, their potential for toxic interaction demands careful consideration. The specific toxicity profile of the ch...
Nowadays, head and neck squamous cell carcinoma (HNSCC) treatment failure is mostly explained by locoregional progression or intrinsic radioresistance. Radiotherapy (RT) has recently evolved with the emergence of heavy ion radiations or new fractionation schemes of photon therapy, which modify the dose rate of treatment delivery. The aim of the present study was then to evaluate the in vitro in...
REVIOUS evidence has shown (KIMBALL, GAITHER and PERDUE 1957,1961; 'KIMBALL, GAITHER and WILSON 1959) that most of the X-ray induced mutations detected by inviability and slow growth after autogamy in Paramecium aurelia originate from reparable premutational lesions. These lesions are subject to repair until the chromosomes duplicate, and only then are they fixed as final mutation. Chromosomal ...
