This study addressed the potential radiosensitizing effect of nicotinamide and/or carbogen on human glioblastoma xenografts in nude mice. U-87MG and LN-Z308 tumors were irradiated with either 20 fractions over 12 days or 5 fractions over 5 days in air-breathing mice, mice injected with nicotinamide, mice breathing carbogen, or mice receiving nicotinamide plus carbogen. The responses to treatment were assessed using local control and moist desquamation. In U-87MG tumors, the enhancement ratios (ERs) at the radiation dose required to produce local tumor control in 50% of the treated mice (TCD50) with nicotinamide and/or carbogen ranged from 1.13 to 1.24 for irradiation in 20 fractions over 12 days. In LN-Z308 tumors, the ERs at the TCD50 with nicotinamide and/or carbogen ranged from 1.22 to 1.40 for irradiation in 5 fractions over 5 days and from 1.11 to 1.30 in 20 fractions over 12 days, respectively. Skin injury was slightly enhanced, with ERs ranged from 1.06 to 1.15 when radiation was combined with carbogen and/or nicotinamide. Thus carbogen and nicotinamide can slightly improve the radiation response of human glioblastoma xenografts. [less ▲]

En 1998, plusieurs études ont clarifié ou confirmé l'effet positif de la radiothérapie dans le cancer du sein in situ, dans différents types de lymphomes non hodgkinien et hodgkinien, et dans le cancer bronchique à petites cellules. Deux métaanalyses par contre semblent remettre en cause la radiothérapie, dans la maladie de Hodgkin de stade avancé et dans l'approche postopératoire du cancer ronchique à non petites cellules. Ces méta-analyses comportent toutefois d'importantes faiblesses et doivent être interprétées de façon critique. Dans le domaine technique de la radio-oncologie, les progrès spectaculaires de la planification assistée par ordinateur et l'intégration de l'imagerie IRM peuvent maintenant s'appliquer aussi à la curiethérapie. Enfin, la radiothéraple dans les affections non oncologiques suscite un nouvel intérêt, comme par exemple la curiethérapie intracoronarienne, un traitement prometteur pour prévenir la resténose coronarienne.

The potential of zalcitabine (ddC) to act as an ionizing radiation response modifier was tested on exponentially growing human cancer cells in vitro. Two human cell lines, WiDr (colon) and MCF-7 (breast) were exposed to ddC at 10 p M concentration for various lengths of tide (18, 24, 48 and 72 h). On the WiDr cell line the dual effect of concentration and duration of exposure prior to irradiation was investigated. Experimental endpoints were clonogenicity and viability, as measured by colony formation assay (CFA) and MTT assay respectively. The impact on cell-cycle distribution prior to irradiation was assessed by flow cytometry using a double labeling technique (propidium iodide and bromodeoxyuridine pulse label). A significant reduction in surviving fraction and viability was observed for WiDr-cells irradiated after pre-exposure to 10 pM for 18, 48 and 72 h as compared to corresponding irradiated controls. At lower concentrations (1 and 5 pM), the radiosensitizing effect was only significant after a 72-h exposure (assessed by CFA). For MCF-7, ddC induced a significant modification of the dose response only with 24 and 48 h preincubation. However, the overall effect was less pronounced as compared to WiDr. Cell-cycle analysis showed accumulation in S-phase, 48 and 72 h after treatment with 10 pM ddC in the WiDr cells, with a progressive shift to late S-phase as shown by the biparametric analysis. The degree of radiosensitization is cell-line dependent with the most important sensitization observed on the most <<radioresistant cell line>>, ix., the cell line with the lowest alpha value and highest SF 2 (WiDr). For WiDr, radiosensitization by ddC depends on the duration of exposure and the concentration of the drug. Received 29 February 1996 Accepted 10 December 1996 [less ▲]

L-hyperthermie consiste en l'élévation de la température du corps ou d'une de ses parties, par des moyens externes au-delà de 41°C. La chaleur a une activité cytotoxique propre et provoque une sensibilisation des cellules aux radiations ionisantes ou à la chimiothérapie. Le gain thérapeutique est environ de 2. Seules les tumeurs superficielles peuvent être traitées adéquatement par les moyens actuels. Les indications sont la palliation de tumeurs superficielles telles que les récidives loco-régionales du cancer du sein, les récidives ganglionnaires de cancers ORL et les cancers de la peau, en particulier les mélanomes [less ▲]
