Accuracy of PET-CT to Assess the Extent of Nodal Disease in Patients with Clinical Stage III Melanoma Following Neoadjuvant Treatment.

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
backgroundClinical stage III melanoma has a high recurrence rate following surgical dissection. The use of neoadjuvant treatment has been shown to improve long-term outcomes when compared with up-front surgery, with the pathological response being the best predictor. Biomarkers predicting responses and possibly allowing surgical de-escalation are missing. We aimed at assessing the correlation between post-treatment positron emission tomography-computed tomography (PET-CT) results and the pathological and long-term outcomes in a cohort of patients treated with a variety of regimens. PATIENTS AND
methodsWith IRB approval, we collected data on all patients with stage III melanoma treated with neoadjuvant intent at our institution since 2011 and assessed the association between their baseline features, post-treatment PET-CT findings, surgical pathological findings, and long-term outcomes.
resultsIn total, 60 patients were identified; the median age was 61 years and 50% were males. The most common regimens used were immunotherapy (IO) in 42% and IO combined with targeted therapy (TT) in 48%. The imaging and pathological response rates were correlated at 60% and 65%, respectively. Both imaging and pathological response rates were higher for those treated with IO+TT than those with IO only, yet the presence of a major pathological response was predictive of a decreased risk of recurrence only in patients treated with IO. Overall, 67% had discordance in the number of involved lymph nodes between the PET-CT and pathological findings. PET-CT underestimation of lymph node involvement was associated with recurrence in those treated with IO only.
conclusionsPost-neoadjuvant PET-CT findings should be interpreted with caution when considering the extent of the surgical dissection.
