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

purposePostoperative infectious complications have a negative impact on survival outcomes in patients with gastric cancer. It is recently reported that preoperative chemotherapy may eliminate this negative impact. This study aimed to confirm whether preoperative chemotherapy can eliminate the negative impact of postoperative infectious complications (IC) on survival outcomes and elucidate the association between postoperative infectious complications and recurrence patterns.

methodsWe retrospectively reviewed data of 86 patients who received preoperative chemotherapy with docetaxel, cisplatin, and S-1 followed by R0 gastrectomy at the Kitasato University between 2006 and 2016. Patients who developed grade II or higher infectious complications during hospitalization were grouped into the IC group, while others were grouped into the non-IC (NIC) group. Survival outcomes and recurrence patterns were analyzed between the two groups.

resultsInfectious complications with Clavien-Dindo classification of grade II or higher were found in 12 patients (14.0%, IC group). The median observational period was 61 months. Overall survival and progression-free survival were similar in the IC and NIC groups. Recurrence occurred in 39 patients. The proportions of peritoneal and lymph node recurrences were not significantly different between the two groups. However, the proportion of distant metastasis in the IC group was significantly higher than that in NIC group (3/4 [75%] vs. 9/35 [17%], p = 0.04).

conclusionsPathological stage after neoadjuvant therapy plays a stronger role in recurrence than postoperative complications. Lymph node and peritoneal metastasis may be suppressed by preoperative chemotherapy.
