Impact of surgery associated with radiotherapy on the prognosis of breast cancer - Guinea Breast Cancer Cohort Study.
Article in Cancer reports (Hoboken, N.J.), 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers, 3 of them syntheses that pooled it.
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
backgroundIn a country where radiotherapy (RT) is not available, advocacy based on the relevance of surgery + adjuvant RT in locoregional control and survival is needed.
aimTo evaluate the impact of surgery with RT on local control and survival compared to surgery alone in breast cancer (BC). METHODS AND
resultsBetween 2007 and 2016, 210 patients with BC were retrospectively reviewed, of which 90 patients underwent surgery with RT (group 1) and 120 patients' surgery (group 2). There were several treatment combinations, including surgery combined with neoadjuvant chemotherapy [ACT], RT, and ACT. The results showed 88 (41.9%) cases of relapse, including 31 (34.4%) (group 1) and 57 (47.5%) (group 2) (p = .046). Recurrence occurred after a mean time of 1.5 years in group 1 versus 0.66 years in group 2 (p = .006). The 5-year overall and BC-specific survivals were 49.5% and 62.5%, respectively. The 5-year survival was 60.0% (group 1) and 40.0% (group 2) (p < .05). In a multivariate analysis by Cox model, we found that the risk of death was 1.90 81 (95% CI [1.17 09-3.0701]) higher in group 2 (p = .009022), 1.69 85 (95% CI 1.00087-23.86157) in obese patients and decreased by 0.21 (95% CI [0.129-0.368]) in patients who did not relapse (p < .001).
conclusionIn this study with several combination therapies, we cannot confirm that RT improves mainly locally advanced BC prognosis regardless of systemic treatment. However, we found that the risk of death correlated with the absence of RT, overweight, and risk of recurrence. Consideration of combinations of locoregional and systemic therapies, clinicopathological and biological data could improve the relevance of these results with a large sample size.
