Progression to Lymph Node Metastasis After Spontaneous Regression of Pulmonary Adenocarcinoma Following Biopsy.

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
BACKGROUND/
aimSpontaneous regression (SR) of cancer, which indicates the natural disappearance of malignant tumors, is rare. Little is known about the mechanisms underlying SR; however, immunological reactions, infections, injuries, and medications have been presumed. Among previously reported cases of SR, lung cancer cases have been extremely limited. CASE REPORT: Here, we present a case of lymph node metastasis exacerbation after SR of a primary adenocarcinoma following a biopsy. After complete disappearance of the primary site tumor, metastatic lymph nodes in the mediastinum gradually increased in size as a single lesion. Local treatment with resection and radiotherapy was effective for this metastasis, without recurrence for >3 years.
conclusionThis is an interesting case of SR of pulmonary adenocarcinoma with inconsistent features in the primary and metastatic lesions. When physicians encounter exacerbation of metastatic sites with SR of the primary site in lung cancer, local intervention may be considered as a curative treatment.
