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.

2 · The registry

The trial behind it

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.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

backgroundThe esophagus has no serosa; therefore, esophageal cancer may quickly invade its adjacent organs. In recent years, reports of conversion surgery (CS) and salvage surgery (SS) have described resection of esophageal cancer previously considered unresectable, with the addition of intensive preoperative chemotherapy or chemoradiotherapy. Currently, there is no established method for determining whether tumor excision is possible. Additionally, differences in surgical approaches between facilities may influence outcome after resection. However, the option for resection is considered a significant factor in determining a patient's prognosis.

methodsPatients who were diagnosed with advanced-stage (T3 or higher) squamous cell carcinoma of the esophagus and subsequently underwent resection with CS or SS were included in the study. Resection was performed through a small thoracotomy using a thoracoscope. Clinicopathologic factors, such as complete resection rate (R0) and prognosis, were investigated.

resultsA total of 49 surgeries were conducted: 39 CS and 10 SS cases. The male-to-female ratio was 37:12. R0:R1:R2 equals 42:3:4, and the R0 resection rate was 85.7%. The 5-year survival rates for CS and SS cases were 69.2% and 32.1%, respectively. The 5-year survival rates for R0, R1, and R2 resections were 63.4%, 0.0%, and 25.0%, and those for R0 and R1 + 2 resections were 63.4% and 14.3%, respectively, indicating that the prognosis for R0 resection cases was significantly better (P = 0.001 and P = 0.001, respectively). Regarding chemotherapy for CS, 29 patients received 5-FU and cisplatin therapy, whereas 10 patients received 5-FU, cisplatin, and docetaxel (DCF) therapy. After 2015, the ratio of DCF was significantly high, and the R0 resection rate was 100% in patients who received DCF therapy.

conclusionsIn this study, a satisfactory R0 rate was achieved using the magnifying effect of the thoracoscope while ensuring safety during thoracotomy.

trial registrationThis was a single-center cohort study wherein clinical data were retrospectively registered. This study was approved by the Chiba Cancer Center review board (H29-262). All procedures adhered to the ethical standards of the responsible committee on human experimentation and the Helsinki Declaration of 1964 and its later amendments.
