Potential efficacy of local therapy for progressive lesions after nivolumab in patients with recurrent or metastatic squamous cell carcinoma of the head and neck.

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
backgroundIn recurrent or metastatic squamous cell carcinoma of the head and neck (R/M SCCHN), local therapy (LT) such as surgery or radiotherapy can be treatment options for improved survival or quality of life. To date, however, few reports have addressed the efficacy of LT for sites of disease progression after immune checkpoint inhibitors, including other cancers.
methodsWe conducted a retrospective analysis of patients with R/M SCCHN originating from the oral cavity, oropharynx, hypopharynx, and larynx and treated with nivolumab. We extracted patients undergoing salvage LT or palliative radiotherapy (RT) to the selected progressive lesion at any time after initiation of nivolumab.
resultsTwenty-four patients received LT. Salvage LT was performed in 9 (37.5%) patients, including surgery and definitive RT in 5 and 4 patients, respectively. Palliative RT was performed in 15 (62.5%) patients. LT was provided in 10 (41.7%) patients for oligoprogressive disease. Twelve (50.0%) patients received subsequent systemic therapy immediately after LT. Classification based on patient treatment divided the population into four subgroups with different prognoses (salvage LT followed by subsequent systemic therapy [n = 3], salvage LT alone [n = 6], palliative RT followed by subsequent systemic therapy [n = 9], and palliative RT alone [n = 6]). Median OS in this order was 24.5, 9.0, 7.3, and 2.4 months (p = 0.001). All patients in the salvage LT followed by subsequent systemic therapy group continued nivolumab.
conclusionIn R/M SCCHN patients who have received nivolumab, salvage LT for the selected progressive lesion with continuation of nivolumab potentially provides an excellent survival prognosis.
