Comparison between 1-week and 2-week palliative radiotherapy courses for superior vena cava syndrome.
Article in Radiation oncology journal, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
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
purposeThe aim of this study was to evaluate the effectiveness of palliative radiation therapy (RT) for superior vena cava (SVC) syndrome from lung cancer and to compare the 2-week and 1-week schedules. MATERIALS AND
methodsA retrospective study was conducted on lung cancer patients with palliative RT for SVC syndrome. Patients received 30 Gy in 10 fractions (2-week group) or 20 Gy in 5 fractions (1-week group) between July 2012 and June 2022. Treatment outcomes were evaluated at 1 to 2 months after RT. The tumor response and recanalization were evaluated based on the computed tomography (CT).
resultsOf the 39 patients, 24 received a 2-week course RT and 15 received a 1-week course of RT. The most common SVC-associated symptoms were edema (51.3%) and dyspnea (43.6%). There were no significant differences in performance status, histology, and grade of SVC. Symptom relief in symptomatic patients was comparable (85.7% in the 2-week group vs. 91.6% in the 1-week group; p = 0.581). There were no significant differences between the 2-week and 1-week groups in recanalization rates (62.5% vs. 60.0%; p = 0.876), tumor responses (75% vs. 60.0%; p = 0.876), and 6-month overall survival rates (29.2% vs. 36.4%; p = 0.726). In each of the two groups, one patient was consulted for re-irradiation. The median survival were 3.7 months for the 2-week group and 4.4 months for the 1-week group.
conclusionIn patients with SVC syndrome, the palliative effect of a 1-week course was equivalent to that of a 2-week course. Given the poor prognosis, a 1-week course may be an option.
