Isolated Limb Perfusion on Nonmelanoma Skin Cancer for Limb Salvage: A Series of Four Cases.
Article in Cureus, 2020. 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 cancer (NMSC) is more prevalent than all the other cancers combined together. The most common regions affected by skin cancer are the head and neck, but there is a large proportion of the cases located on the limbs. They could be bulky, very extensive and/or located in specialized regions like the hands or near to a joint. Most of those cases should be amputated, with several compromises of the function and a negative impact on the patients' quality of life. Isolated limb perfusion is a proven alternative to limb salvage on soft tissue sarcomas, but there are just a few reports about its application on non-melanoma skin cancer. The aim of the article is to describe the outcomes and prove the benefits and effectiveness to avoid limb amputation when using isolated limb perfusion on locally advanced non-melanoma skin cancer. We present clinical, retrospective study as a case series report. The study includes four patients with locally advanced non-melanoma skin cancer in the limb - three cases with squamous cell carcinoma (SCC), and one patient with Merkel cell carcinoma (MCC) who underwent to tumor necrosis factor-alpha (TNFα) and melphalan based isolated perfusion of the limb (TM-ILP). Toxicity, clinical response, and limb salvage were described. Patients were treated in the oncological surgical department in a referral hospital in Mexico. The limb salvage rate was achieved in 75%. All patients had a favorable response to TM-ILP. Complete response of the tumor was noted on two (50%) of the patients (one with histopathological confirmation), the other 50% had a partial response to the TM-ILP. No serious toxicity related to TM-ILP was observed. One patient (25%) developed regional lymph involvement six months after perfusion. Lymphadenectomy was performed, and the patient subsequently has a six-year disease-free survival. In conclusion, TM-ILP could be an effective, reliable, and safe therapy on limb salvage in selected patients with non-melanoma skin cancer who are not adequate surgical candidates.
