Image-Guided Superficial Radiation Therapy for Squamous Cell Carcinoma In Situ of the Nasal Ala in a High-Risk Surgical Candidate: A Case Report.
Article in Cureus, 2026. 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
Nonmelanoma skin cancers (NMSCs), including squamous cell carcinoma in situ (SCCIS), are common and considered curable with early intervention; however, management must be individualized based on tumor characteristics and patient-specific factors. While surgical approaches such as Mohs micrographic surgery are the standard of care for high-risk anatomical sites, nonsurgical modalities are essential for patients with significant comorbidities. We present the case of an 80-year-old male with recurrent SCCIS of the right nasal ala whose medical history was significant for renal transplantation on chronic immunosuppressive therapy, chronic obstructive pulmonary disease (COPD) requiring supplemental oxygen, and impaired mobility, making him a poor surgical candidate for Mohs surgery or complex reconstruction. The patient elected treatment with image-guided superficial radiation therapy (IG-SRT), a noninvasive modality that incorporates high-resolution dermal ultrasound (HRDUS) for precise tumor measurement and treatment planning. Initial HRDUS demonstrated a tumor depth of 2.34 mm. He subsequently completed 20 fractions over six weeks, receiving a total dose of 5666.20 cGy. Expected radiation-induced skin changes developed during treatment, with a peak Radiation Therapy Oncology Group (RTOG) toxicity score of 2. Serial HRDUS demonstrated progressive tumor regression and no detectable residual tumor six weeks after treatment completion. The patient was pleased with the cosmetic outcome and experienced no alar distortion or airway compromise. This case highlights IG-SRT as a feasible, tissue-sparing treatment option for recurrent SCCIS in medically complex patients who are poor surgical candidates while emphasizing the value of HRDUS for treatment planning and response monitoring.
