Mesenteric Lymph Node Involvement as a Prognostic Factor in Ovarian Cancer: A Study Using a Standardized Detection Method.

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.
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
backgroundMesenteric lymph node (MLN) involvement is frequently observed in patients undergoing cytoreductive surgery for ovarian cancer (OC) with rectosigmoid invasion. However, MLN detection methods are not standardized, and the clinical significance of MLN involvement remains controversial. This study aimed to investigate the clinical significance of MLN involvement in patients with OC using a standardized detection method.
methodsThe study included 171 patients with stage II, III, or IV OC who underwent cytoreductive surgery. The analysis detected MLN in patients who underwent rectosigmoid resection in the same manner as for colorectal cancer: systematic regional lymph node dissection followed by systematic extraction and histopathologic examination of MLN.
resultsOf the 171 patients, 57 underwent rectosigmoid resection. In 56 patients (98.2 %), MLNs were detected, with a median of nine (range, 0-51) dissected nodes. Histopathologic examination confirmed MLN involvement in 30 of these 57 patients. The independent prognostic factors for progression-free survival identified by multivariate analysis were residual tumor status (P = 0.002), ascitic cytology (P = 0.034), and MLN involvement (P = 0.010). Among the 86 patients who underwent complete cytoreductive surgery, MLN involvement was significantly associated with worse prognosis (P < 0.001). However, for the 85 patients who underwent optimal or suboptimal cytoreductive surgery, MLN involvement was not a significant prognostic factor.
conclusionsIn patients with OC, MLN involvement is an important prognostic factor, particularly for those undergoing complete cytoreductive surgery. Evaluation of MLNs using a standardized detection method in the same manner as for colorectal cancer may help identify patients at higher risk for a poor prognosis.
