Randomized Controlled Trial Multicenter Study Clinical Trial
Perioperative granulocyte colony-stimulating factor does not prevent severe infections in patients undergoing esophagectomy for esophageal cancer: a randomized placebo-controlled clinical trial.
Esophagectomy for esophageal cancer is associated with substantial postoperative morbidity as a result of infectious complications. In a prior phase II study, granulocyte colony-stimulating factor (G-CSF) was shown to improve leukocyte function and to reduce infection rates after esophagectomy. The aim of the current randomized, placebo-controlled, multicenter phase III trial was to investigate the clinical efficacy of perioperative G-CSF administration in reducing infection and mortality after esophagectomy for esophageal cancer. ⋯ Perioperative administration of G-CSF failed to reduce postoperative morbidity, infection rate, or mortality in patients with esophageal cancer who underwent esophagectomy.

Randomized Controlled Trial Clinical Trial
The role of surgery in primary gastric lymphoma: results of a controlled clinical trial.
We began a controlled clinical trial to assess efficacy and toxicity of surgery (S), surgery + radiotherapy (SRT), surgery + chemotherapy (SCT), and chemotherapy (CT) in the treatment of primary gastric diffuse large cell lymphoma in early stages: IE and II1. ⋯ In patients with primary gastric diffuse large cell lymphoma and aggressive histology, diffuse large cell lymphoma in early stage SCT achieved good results, but surgery was associated with some cases of lethal complications. Thus it appears that CT should be considered the treatment of choice in this patient setting. Current clinical classifications of risk are not useful in defining treatment.
