Prevalence and clinicopathological characteristics of de novo metastatic cancer at a major radiotherapy centre in West Africa: a cross-sectional 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
Background: Cancer is a major public health challenge in West Africa, with a significant proportion of cancer-related deaths attributed to distant metastasis. De novo metastatic cancer (DnMC), where metastasis is detected at diagnosis, presents considerable therapeutic challenges, particularly in limited-resource settings where novel treatments are often unavailable and/or unaffordable. Aim: To determine the prevalence, incidence and clinicopathological characteristics of patients diagnosed with DnMC at a major radiotherapy center in West Africa. Methods: This was a single-institution-based quantitative cross-sectional study. Data on the prevalence and incidence of DnMC were retrieved from a hospital-based cancer registry whereas patients' demographic and clinicopathologic data were extracted from patients' medical records and analysed with STATA software (version 16). Descriptive statistics were used to summarise patient- and tumour-related characteristics. Results: The prevalence and incidence of DnMC were 15.2% and 5.3%, respectively, with a 36% overall incidence rate of metastatic cancer. The mean age was 50.9 years (SD 15.2), ranging from 15 to 90 years, with a male-to-female ratio of 1:1.6. Also, 28.8% had a history of alcohol intake whereas 13.7% were (tobacco) smokers. Additionally, 10.3% of the patients had a positive family history of cancer. Pain (28.2%) was the most common presenting symptom, followed by bleeding (16.5%). In all, 34.9% had an Eastern Cooperative Oncology Group (ECOG) performance status of 0 whereas 33.3% were ECOG 1. The gastrointestinal tract (25.8%) and breasts (17.6%) were the most frequent primary cancer sites, whereas 4.4% had metastatic cancers of unknown primary origin. The most frequent sites of distant metastasis were the lungs (34.6%), liver (28.9%) and bone (13.8%). Adenocarcinoma was the most prevalent histological type (35.2%). Conclusion: There was a relatively high rate of DnMC compared with high-income countries, emphasising the need for early detection and expanded access to comprehensive cancer care in limited-resource settings.
