Extended Lymph Node Sampling During Surgery for Pediatric Renal Tumors Concerning for Malignancy Does Not Increase Postoperative Complication Rates.

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
purposeAlthough Children's Oncology Group renal tumor protocols mandate lymph node sampling during extirpative surgery for pediatric renal tumors, lymph node sampling is often omitted or low yield. Concerns over morbidity associated with extended lymph node sampling have led to hesitancy in adopting a formal lymph node sampling template. We hypothesized that complications in children undergoing lymph node sampling for renal tumors would be rare, and not associated with the number of lymph nodes sampled. MATERIALS AND
methodsA single-institution, retrospective review of patients aged 0-18 years undergoing extirpative renal surgery with lymph node sampling for a suspected malignancy between 2005 and 2019 was performed. Patients with 0 or an unknown number of lymph nodes sampled or <150 days of follow-up were excluded. A "clinically significant" complication was defined as any Clavien complication ≥III, small-bowel obstruction, chylous ascites, organ injury, or wound infection. The number of lymph nodes sampled and its influence on the odds of experiencing a clinically significant complication was examined.
resultsA total of 144 patients met inclusion criteria. Median patient age was 38 months. Twenty-one patients (15%) had a clinically significant complication, the most common of which was ileus/small-bowel obstruction (n=16). In a multivariable analysis, increased lymph node yield was not found to influence the odds of experiencing a clinically significant complication (
conclusionsIn this cohort, there was no statistically significant difference in clinically significant complications in patients who underwent more extensive lymph node sampling during surgery for a suspected malignant pediatric renal tumor. Future studies on protocol adherence, staging accuracy, and survival trends using a lymph node sampling template in these patients should be performed.
