Regional control after precision lymph node dissection for clinically evident melanoma metastasis.
Article in Journal of surgical oncology, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
introductionCompletion lymph node dissection (CLND) for microscopic lymph node metastases has been replaced by observation; however, CLND is standard for clinically detectable nodal metastases (cLN). CLND has high morbidity, which may be reduced by excision of only the cLN (precision lymph node dissection [PLND]). We hypothesized that same-basin recurrence risk would be low after PLND.
methodsRetrospective review at four tertiary care hospitals identified patients who underwent PLND. The primary outcome was 3-year cumulative incidence of isolated same-basin recurrence.
resultsTwenty-one patients underwent PLND for cLN without synchronous distant metastases. Reasons for forgoing CLND included patient preference (n = 11), comorbidities (n = 5), imaging indeterminate for distant metastases (n = 2), partial response to checkpoint blockade (n = 1), or not reported (n = 2). A median of 2 nodes (range: 1-6) were resected at PLND, and 68% contained melanoma. Recurrence was observed in 33% overall. Only 1 patient (5%) developed an isolated same-basin recurrence. Cumulative incidences at 3 years were 5.0%, 17.3%, and 49.7% for isolated same-basin recurrence, any same-basin recurrence, and any recurrence, respectively. Complications from PLND were reported in 1 patient (5%).
conclusionsThese pilot data suggest that PLND may provide adequate regional disease control with less morbidity than CLND. These data justify prospective evaluation of PLND in select patients.
