Esophageal cancer with high incidence and mortality rates plays a major clinical and social role. Adjuvant radiotherapy, chemotherapy and combined chemoradiation are used for esophageal cancer ...patients after esophagectomy. Outcomes of these approaches are analyzed in the literature. Three randomized clinical trials and three retrospective series were reviewed; they provided a representative pattern of available data. From their analysis some critical aspects emerged in relation to the statistical design of the few, now available randomized clinical trials. The number of patients enrolled is too low to verify minimal improvements in outcomes. Therefore, to-date there is not definite evidence in the literature supporting the role of adjuvant chemotherapy in patients undergoing surgery for esophageal cancer.
Surgery alone is currently still accepted as the principal therapy for cure for patients with localized non-small cell lung cancer. The optimal therapy in locally advanced and unresectable stage III ...disease remains unclear. The limited performance of each single therapeutic strategy (surgery, radiotherapy, or chemotherapy) in the treatment of locally advanced non-small cell lung cancer accounted for the rationale of the many attempts at improvement by integrating the different approaches. In recent years, to improve clinical outcome, chemotherapy or chemoradiation followed by surgery, and definitive chemoradiation have commonly been used. Despite numerous phase-II trials, little evidence from randomized phase-III trials has been generated. The ongoing randomized trials will probably provide more reliable indications to define the management of the large number of patients with locally advanced disease.
