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 therapeutic value of systematic lymphadenectomy for early-stage epithelial ovarian cancer (EOC) is controversial. This study evaluates the survival impact and adverse events of systematic pelvic and para-aortic lymphadenectomy in patients with pT1 and pT2 EOC.

methodsA retrospective investigation was performed using data from patients with pT1 and pT2 EOC at multi-institutions belonging to the Sankai Gynecologic Study Group (SGSG). We selected patients who had undergone systematic pelvic and para-aortic lymphadenectomy (Group LA) (n = 284) and patients who had not undergone lymph node resection (Group no-LA) (n = 138). Outcomes for patients and peri-operative adverse events were compared between the two groups.

resultsThe median operation time was significantly longer in Group LA (288 min) than in Group no-LA (128 min) (P < 0.0001). Total blood loss was significantly higher in Group LA, 43.7 % of patients receiving blood transfusions. There were no significant differences between the treatment groups for progression-free survival (PFS) or overall survival (OS). However, for patients with pT2, PFS was significantly longer in Group LA than in Group no-LA (P = 0.0150). Lymph node metastases were detected in 23 cases (8.1 %) and these patients had significantly shorter PFS than those without metastasis (P = 0.0409). The outcome for patients who underwent chemotherapy after surgery was significantly improved in the Group no-LA, but no improvement was observed in Group LA.

conclusionsSystematic lymphadenectomy may improve outcomes only in pT2 EOC patients with acceptable peri-operative events. Furthermore, accurate surgical staging may avoid unnecessary adjuvant chemotherapy in selected early-stage cases.
