Prognosis of primary central nervous system lymphoma treated with radiotherapy alone.
Article in Japanese journal of radiology, 2012. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
purposeStandard treatment for patients with primary central nervous system (CNS) lymphoma involves combining high-dose methotrexate-based chemotherapy and radiation. However, chemotherapy is sometimes contraindicated, and radiotherapy alone becomes the only option. We retrospectively investigated the clinical outcomes of primary CNS lymphoma patients treated with radiotherapy alone. MATERIALS AND
methodsBetween 1983 and 2006, 35 patients (median age 69 years, range 37-89 years) with primary CNS lymphoma were treated with radiotherapy alone. Of these, 74 % had an Eastern Cooperative Oncology Group performance status (PS) of 2-4. Most patients (91 %) received whole-brain irradiation with or without irradiation boost to the tumor site (median dose 50 Gy, range 22-50 Gy); remaining patients received partial brain irradiation.
resultsMedian follow-up time was 20 (range 1-152) months, median survival time was 20 months, and the 1- and 2-year overall survival rates were 65 and 32 %, respectively. Median survival in patients aged <70 and ≥ 70 years was 26 and 10 months, respectively (p = 0.01).
conclusionMedian survival with radiotherapy alone was 20 months. Patients aged <70 years have a better prognosis than those ≥ 70 years.
