Feasibility of Proton Beam Therapy for Para-Aortic Lymph Node Recurrence in Patients With Gynecologic Cancer After Pelvic Irradiation: A Case Series.

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
aimIrradiation of para-aortic lymph node recurrences in patients with prior pelvic irradiation raises concerns about overlapping irradiated fields, which should be minimized to reduce severe adverse events. We report six gynecologic cancer patients treated with proton beam therapy for para-aortic lymph node recurrence after pelvic irradiation.
methodsSix patients who received proton beam therapy for para-aortic lymph node recurrence after pelvic irradiation between 2010 and 2022 were included. Overlapping fields were assessed using the 50% dose distance between the initial and proton therapy fields.
resultsA 5- to 10-mm overlap was observed in three patients. Grade 2 rectal hemorrhage occurred in three patients, grade 3 hematuria in two, and grade 4 sigmoid perforation in one. These adverse events were linked to pelvic irradiation and peritoneal dissemination. Among five patients who died, the median survival after proton therapy was 13 months (range: 9-34). One patient survived with disease at 34 months. Re-enlargement of treated para-aortic lymph nodes was not observed in four patients.
conclusionsProton beam therapy was well-tolerated and achieved favorable local control in para-aortic lymph node recurrence after pelvic irradiation. It may be a useful option for gynecologic cancer patients with overlapping irradiated fields.
