Investigation of somatic mutation profiles and tumor evolution of primary oropharyngeal cancer and sequential lymph node metastases using multiregional whole-exome sequencing.

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
Lymph node (LN) metastasis is an important factor in determining the treatment and prognosis of oropharyngeal squamous cell carcinoma (OPSCC). Here, we compared the somatic mutational profiles and clonal evolution of primary and metastatic LNs using multiregion sequencing of human papilloma virus (HPV)-positive OPSCC and HPV-negative OPSCC. We performed high-depth whole-exome sequencing (200×) of 76 samples from 18 patients with OPSCC (10 HPV-positive and 8 HPV-negative), including 18 primary tumor samples, 40 metastatic LN samples, and 18 normal tissue samples. Among 40 metastatic LNs, 22 showed extranodal extension (ENE). Mutation profiles of HPV-positive OPSCC and HPV-negative OPSCC were similar to those reported previously. Somatic mutations in CDKN2A and TP53 were frequently detected in HPV-negative OPSCC. Somatic mutations in HPV-positive OPSCC samples showed APOBEC-related signatures. Somatic mutations from metastatic LNs showed a different pattern than the primary tumor. Somatic mutations acquired in the WNT pathway during metastasis showed a significant relationship with ENE. Clonal evolution analysis of primary and metastatic LNs showed that, in some cases, each metastatic LN originated from a different primary tumor sub-clone.
