“…The treatment dilemma is confounded by data that are not clear on the overall benefi t of multimodality therapy. Several meta-analyses have suggested a benefi t from multimodality therapy, 12,[22][23][24][25] but the data do not reach statistical signifi cance in some of these studies. [22][23][24] However, many of these data demonstrate heterogeneic patient populations without considering tumor biology or pathological response.…”

“…To further investigate the value of the trimodal approach vs surgery alone, several meta-analyses were performed. With differences in the endpoint analyzed and background of the evaluated studies, few of them revealed only a nonsignificant trend in favor of RT-CT, while most of them showed a significant benefit (70)(71)(72)(73)(74)(75)(76)(77). If the role of preoperative RT-CT over surgery alone seems well-established, its benefit over preoperative CT alone seems more controversial.…”

“…Doses varied from 20 Gy to 40 Gy, but even in the trial with the higher doses, the fractionation was far from optimal (40 Gy in eight fractions). A meta-analysis on 1,147 patients was performed and has shown a 11% reduction in mortality (confidence interval 95%: 0.78-1.01), p = 0.062 (12). The benefit is limited to 3% increase in survival at 5 years.…”
