Is cryosurgery a feasible local therapy for bone metastatic prostate cancer?
Article in Singapore medical journal, 2018. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
introductionThis study aims to assess whether cryosurgery is a feasible local therapy for bone metastatic prostate cancer (bmPCa).
methodsA total of 23 patients with bmPCa who received cryosurgery and adjuvant androgen deprivation therapy (ADT) were included in the cryosurgery group (Group 1). Another 23 matched patients who received only ADT served as the control (Group 2). Prostate-specific antigen (PSA) nadir level, time to PSA nadir, time to castration-resistant prostate cancer (CRPC), progression-free survival and therapy response of bone metastases were compared between the groups.
resultsThe median follow-up time in Group 1 and Group 2 patients was 37 (range 19-53) months and 42 (range 24-56) months, respectively. Patients in Group 1 had fewer local complications, lower PSA nadir level (0.23 ng/mL vs. 4.01 ng/mL; p = 0.024), shorter median time to PSA nadir (3 months vs. 7 months; p < 0.001), longer median time to CRPC (36 months vs. 27 months; p = 0.002) and longer progression-free survival (35 months vs. 26 months; p = 0.003) compared to those in Group 2. Therapy responses of bone metastases were similar in the two treatment groups (p = 0.689).
conclusionCryosurgery is a feasible local therapy for bmPCa patients with prostate volume less than 50 mL and without bulk tumours outside the prostate capsula. Cryosurgery may decrease PSA nadir level, local complications and time to PSA nadir, delay time to CRPC and improve progression-free survival.
