1 · What the graph read from it

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.

2 · The registry

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

Follicular dendritic cell sarcoma is a rare malignant tumor originating from follicular dendritic cells. We present the first report of such a sarcoma of the palatine tonsils that developed as a radiation-induced sarcoma. A 78-year-old man, who had undergone chemoradiotherapy for hypopharyngeal and esophageal cancer 7 years prior, presented with discomfort during swallowing. Endoscopic pharyngeal examination revealed a tumor in the right palatine tonsil which was histopathologically diagnosed as a follicular dendritic cell sarcoma. The tumor also met the diagnostic criteria for radiation-induced sarcoma. Positron emission tomography/computed tomography revealed abnormal uptake in the right palatine tonsil and bilateral cervical lymph nodes; no distant metastases were detected. The patient underwent tumor resection using the mandibular swing approach, pharyngeal reconstruction using an anterolateral thigh flap, bilateral neck lymph node dissection, and tracheostomy. Postoperative radiotherapy was not administered because of previous irradiation; however, no apparent recurrence or metastasis was observed 4 years after surgery. Follicular dendritic cell sarcoma can develop over an extended period after previous irradiation. Extended resection with a negative margin may be pivotal in treating follicular dendritic cell sarcoma when postoperative radiotherapy cannot be administered.
