We tested the relationship between radiation-induced mucositis and oral neutrophil counts. Patients and Methods: Oral neutrophil counts were obtained for ten patients with head and neck cancer who received radiotherapy of the pharynx and oral cavity. Four patients received additional chemotherapy (5-FU, Mitomycin). Counts were obtained before and during treatment; four healthy volunteers were included in the study as well. For evaluation, a quantitative mouth rinse assay, including neutrophil-staining with acridin-orange, was applied. Results: We observed large inter-individual variations with respect to neutrophil counts for patients and control persons (Table 1). During treatment (irradiation or chemoirradiation), large intra-individual variations were seen additionally (Figure 1). We found a correlation between neutrophil counts and clinical reaction grade. Neutrophil counts increased with increasing mucositis (Figure 2). This increase was more pronounced for patients treated with chemoirradiation compared to radiation alone. Treatment breaks at weekends had no clear influence on neutrophil counts. Conclusions: We observed a weak correlation between neutrophil counts and clinical reaction grade. However, the variations in neutrophil counts are too large to utilize this parameter as a surrogate for clinical mucositis grading. The assumption that a decrease in oral neutrophils is associated with radiation-induced mucositis was clearly negated."],["dc.identifier.doi","10.1007/s00066-003-1121-1"],["dc.identifier.isi","000185950700002"],["dc.identifier.pmid","14566474"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/45227"],["dc.notes.status","zu prüfen"],["dc.notes.submitter","Najko"],["dc.publisher","Urban & Vogel"],["dc.relation.issn","0179-7158"],["dc.title","Radiation-induced mucositis and neutrophil granulocytes in oral mucosa"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.peerReviewed","yes"],["dc.type.status","published"],["dspace.entity.type","Publication"]]

Cells irradiated in G(0)/G(1) phase with 200 kV X rays were treated with wortmannin before or after irradiation. Chromosome-type and chromatid-type aberrations were scored in metaphase cells by either Giemsa staining or FISH. Moreover, DNA-PK activity was measured in the absence and presence of wortmannin. In irradiated G(0)/G(1)-phase WiDr cells, only chromosome-type aberrations, including simple and complex exchanges and excess acentrics, were observed. After addition of 1 to 20 mu M wortmannin, the formation of chromosome-type exchange aberrations was completely suppressed. The irradiated cells displayed exclusively chromatid-type aberrations including simple and complex chromatid exchanges and chromatid/isochromatid breaks. Whether the chromatid-type aberrations arise during G(0)/G(1) as a result of homologous recombination processes coping with damaged DNA or whether DNA damage induced during G(0)/G(1) phase persists until S and G(2) phase and is then processed by homologous recombination pathways must be investigated further.

Cell survival was measured by a colony-forming assay. Survival curves were fitted to the data using the linear quadratic model. Sensitizer enhancement ratios (SER) were calculated at the 37% survival level, and isobologram analysis was applied to test for the drug-radiation interactions. Results: Oxaliplatin as well as cisplatin alone were cytotoxic in both cell lines. In CaSki cells, oxaliplatin and cisplatin significantly increased radiation toxicity. In A549 cells no increase of radiation toxicity was observed after treatment with cisplatin, however, isobologram analysis revealed supra-additive interaction between oxaliplatin and radiation in A549 cells.

Materials and methods: Five tumour cell cultures derived from head and neck squamous cell carcinomas, three cultures derived from pleural effusions of carcinomas of different origin and normal human nasal epithelial cells were analysed in passages 2-4. Expression of FGF7 and its receptor (FGFR2) were determined by the RNase protection assay. Cells were incubated with rHuKGF (10-200 ng ml(-1)) 3 days before or immediately after plating for clonal growth in serum-depleted media. To determine cellular radiosensitivity, single doses of 1-8 Gy X-rays were applied. Colony formation as well as colony size, reflecting the number of cell divisions, was determined after 10-15 days of growth in rHuKGF-treated and control cells. Results: Normal nasal epithelial cells showed a two- to threefold increase in the number of cell divisions due to rHuKGF-treatment. In tumour cell cultures, significant stimulation of proliferation occurred in only one of eight samples. Tumour cells expressed FGF7 mRNA and protein, and low levels of FGFR2 mRNA. The addition of rHuKGF to the medium of the tumour cell cultures influenced neither radiation-induced impairment of proliferation nor clonogenic cell survival. Conclusion: rHuKGF has been shown to ameliorate the radiation tolerance of normal epithelia. The minimum in vitro tumour cell response to rHuKGF compared with normal epithelial cells suggests a potential for selective protection of normal epithelia during radiotherapy. The low FGFR2 expression as well as the FGF7 expression in the tumour cells may contribute to their resistance to rHuKGF treatment."],["dc.identifier.doi","10.1080/0955300021000045682"],["dc.identifier.isi","000180776800005"],["dc.identifier.pmid","12569015"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/46510"],["dc.notes.status","zu prüfen"],["dc.notes.submitter","Najko"],["dc.relation.issn","0955-3002"],["dc.title","Effect of keratinocyte growth factor on the proliferation, clonogenic capacity and colony size of human epithelial tumour cells in vitro"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.peerReviewed","yes"],["dspace.entity.type","Publication"]]
