Early Symptom Patterns by Tumor Laterality, Age at Onset, Stage, and Symptom-to-Treatment Initiation in Patients with Colorectal Cancer.

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 Indonesia incidence of colorectal cancer (CRC) remains high. Information about early symptoms that can offer clinicians insights for timely diagnosis, prompt referral and quick treatment decisions is very limited. This study aims to examine the pattern of CRC early symptoms and its association with tumor laterality, age at onset, metastatic status, and symptom-to-treatment initiation (STI) duration and delay.
methodThis cross-sectional study recruits 258 patients diagnosed with CRC between November 2022 and October 2023 from two distinct study databases. Patient baseline characteristics were also obtained from medical records and through interviews at baseline. Symptom-to-treatment initiation (STI) duration was defined as the number of days between the date of the symptom's onset and the date of the first treatment's initiation. Relative risk estimation for metastatic disease and the STI delay, based on tumor laterality and the age at onset group, were estimated using a log-binomial regression for each early symptom.
resultExperiencing abdominal mass as an early symptom is significantly associated with metastatic disease, specifically in right-sided CRC cases (relative risk/RR=2.08, 95% confidence interval/CI 1.29-3.37, p=0.003). In all study subjects, the median STI duration was 182 days (2-5,082 days), with more than half of the subjects experiencing an STI delay of >180 days. Experiencing rectal mass as an early symptom is significantly associated with a higher risk of STI delay >180 days in early onset CRC (RR=1.97, 95% CI 1.27-3.06, p=0.003) and left sided-CRC cases (RR=1.54, 95% CI 1.13-2.08, p=0.005). The non-specific early symptom of weight loss is associated with a higher risk of STI delay >180 days in right-sided CRC cases (RR=1.73, 95% CI 1.06-2.84, p=0.029).
conclusionThe findings underlined the importance of maintaining a high clinical suspicion, particularly in patients with rectal masses and unexplained weight loss, as they might experience STI delay.
