Intraoperative Adjunctive Mitomycin C and Cryotherapy for Recurrent Conjunctival Papillary Sebaceous Carcinoma.
Article in Case reports in ophthalmology. 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
purposeTo report a case of recurrent conjunctival papillary sebaceous carcinoma that was successfully treated by a combination of surgical resection, intraoperative topical mitomycin C application, and cryotherapy. OBSERVATIONS: A woman in her 80s developed a yellowish papillary tumor pedunculated from the surface of the upper palpebral tarsal conjunctiva in her left eye. She was histopathologically diagnosed as having sebaceous carcinoma by an excisional biopsy. We performed en bloc resection of the lateral one-third of the posterior lamella including the cutaneous margin of the upper eyelid as well as reconstruction of the defected portion by a switch-flap from the ipsilateral lower eyelid. Histopathologically, because the tumor was restricted to the epithelial region with minimal invasion into the tarsus, we diagnosed the patient to have conjunctival papillary sebaceous carcinoma. Nine months after the surgery, the tumor recurred and was resected and treated by intraoperative mitomycin C. Four months later, the tumor regrew at the resected margins and was treated by resection combined with mitomycin C and cryotherapy. After these combination treatments, the tumor did not recur for at least 1 year postoperatively. CONCLUSION AND IMPORTANCE: Although sebaceous carcinoma usually originates from the meibomian gland cells or less frequently from the Zeis or Moll gland cells, it rarely occurs from bulbar or palpebral conjunctival cells. Because sebaceous carcinoma sometimes shows a pagetoid growth pattern, it can recur even after en bloc resection with a negative study for tumor cells at the surgical margins. The recurrent sebaceous carcinoma cells showed an intraepithelial growth pattern. Considering this superficial growth property, it may be effective to apply intraoperative mitomycin C and cryotherapy treatment combined with surgical resection to reduce the possibility of recurrence of presumed conjunctival papillary sebaceous carcinoma, although mitomycin C alone seems to be insufficient as an adjunctive treatment.
