| Popis: | Frequency of local and distant failures after gastrectomy has led to extended lymph nodes dissection to obtain a better locoregional control. However, five year survival rates were not significantly different between patients undergoing D2 and D1 lymphadenectomy, and higher morbidity and post operative deaths were reported in large randomised trials (respectively 25% vs 48% and 4 vs 13%). Additionally, several metanalysis failed to demonstrate a significant survival advantage with adjuvant chemotherapy. The results of the first trial demonstrating one advantage to adjuvant post-operative chemoradiotherapy should modify the standard care. Disease free and overall survival after surgery alone and after surgery and concurrent chemoradiotherapy were respectively 31% vs 48% and 41% vs 50%. The intergroup trial demonstrate that better local control improve survival if radiation fields include stamps, tumour bed, proximal nodal chains and nodes corresponding to D2 extended lymph nodes dissection. Treatment was feasible with few severe toxic effects (1%). Of the 281 patients, 17% stopped treatment because toxic effects. Technical modalities of radiotherapy and post-operative nutrition support, which are critical points of interest for this treatment, are also discussed. |
