Neoadjuvant LHRH analog plus estramustine phosphate combined with three-dimensional conformal radiotherapy for intermediate- to high-risk prostate cancer: a randomized study.

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
objectiveThe objective of this study is to assess the safety and efficacy of a treatment regimen comprising neoadjuvant conventional androgen deprivation therapy (ADT) plus estramustine phosphate (EMP) combined with three-dimensional conformal radiotherapy (3D-CRT) for patients with intermediate- to high-risk prostate cancer.
methodsThirty-nine patients with intermediate- to high-risk prostate cancer classified according to the NCCN practice guidelines recurrence risk group were randomly allocated into two groups: neoadjuvant LHRH agonist plus EMP for 6 months until completion of the 3D-CRT (EMP group, n = 20), or neoadjuvant LHRH agonist alone (LHRH group, n = 19). Both groups received 3D-CRT in daily fractions of 2 Gy for a total dose of 70 Gy. PSA relapse was defined according to the Phoenix definition.
resultsThe median duration of follow-up was 27.1 months. None of the patients died during the follow-up period, but three patients in the LHRH group developed distant metastasis. The 4-year PSA relapse-free survival outcomes for the EMP group and LHRH group were 61.2 and 49.4%, respectively (P = 0.04). Multivariate Cox regression model analyses of the pretreatment PSA level (>20 ng/ml n = 16 vs. < or =20 ng/ml n = 23), grade (G8 or more n = 11 vs. G7 or less n = 28) and modality (LHRH group n = 19 vs. EMP group n = 20) revealed these factors to be independent predictors of PSA relapse after treatment: pretreatment PSA had a relative risk of 3.84 (95% CI: 1.003-14.722), grade had a relative risk of 4.29 (95% CI: 1.093-16.824), and modality had a relative risk of 8.01 (95% CI: 1.867-34.361). No severe toxicities were observed in either group.
conclusionsThe present results indicate that the combination of neoadjuvant ADT plus EMP combined with 3D-CRT sustains freedom from PSA relapse in patients with intermediate- to high-risk prostate cancer. However, this regimen is insufficient for preventing biochemical failure, and an additional intervention such as adjuvant ADT, radiation dose escalation, or both, is required, especially for patients with a pretreatment PSA level of more than 20 ng/ml and high-grade cancer.
