Palliative Irradiation With CyberKnife and Quad Shot Regimen for an Elderly Patient With Lower Lip Cancer.
Article in Cureus, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
A 91-year-old woman noticed a mass on her lower lip and was diagnosed with stage II squamous cell carcinoma (cT2N0M0 as per TNM staging). Due to her advanced age, she and her family declined surgery and opted for radiotherapy (RT) alone (76.0 Gy/38 fractions). The tumor showed a partial response, leading to salvage surgery. Over the next three years, the primary tumor recurred twice, but both recurrences were successfully resected, with no further recurrence afterward. However, 15 months after the last recurrence, she developed submandibular lymph node metastasis and underwent stereotactic radiotherapy (30 Gy/5 fractions) using the CyberKnife, achieving a complete response. Subsequently, multiple metastases appeared in both cervical lymph nodes. She then received intensity-modulated radiotherapy using the Quad-shot method, a type of hypofractionated radiotherapy (44.4 Gy/12 fractions in three cycles). Although a temporary complete response was achieved, cervical lymph node recurrence was subsequently observed. She passed away at the age of 97, six months after the final RT. Significantly, she maintained a good quality of life without significant pain or skin metastases and passed away peacefully at home.
