1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Abstract

aimThe aim of this study was to evaluate the effects of radiotherapy plus concurrent weekly cisplatin chemotherapy on the postoperative recurrence of mediastinal lymph node metastases in esophageal cancer patients.

methodsNinety-eight patients were randomly enrolled to receive either three-dimensional conformal radiotherapy alone (group A) or concurrent chemoradiotherapy (group B). A radiation dose of 62-70 Gy/31-35 fractions was delivered to the recurrent tumor. Furthermore, the patients in group B simultaneously received weekly doses of cisplatin (30 mg/m(2)), and the survival outcomes and toxic effects were compared.

resultsThe response rate of group B (91.8%) was significantly greater than that of group A (73.5%) (χ(2) = 5.765, P = 0.016). The 1- and 3-year survival rates of group B (85.7% and 46.9%, respectively) were also greater than those of group A (69.4% and 28.6%, respectively). However, there were no significant differences in the 5-year survival rates. The numbers of patients who died of distant metastases in groups A and B were 13 (26.5%) and 5 (10.2%), respectively (χ(2) = 4.356, P = 0.036). Acute radiation-related esophagitis and granulocytopenia in group B was frequent. However, intergroup differences in terms of late toxicity were not significant.

conclusionsThree-dimensional conformal radiotherapy (3DCRT) is a practical and feasible technique to treat the recurrence of mediastinal lymph node metastases of postoperative esophageal cancer. In addition, concurrent chemotherapy can increase local tumor control, decrease the distant metastasis rate, and increase the long-term survival rate.
