Clinicopathological characteristics and prognostic outcomes of pregnancy-associated colorectal cancer: A 24-year experience.
Article in World journal of gastroenterology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundColorectal cancer (CRC) during pregnancy poses significant risks to both maternal and fetal health; however, this topic remains under researched globally.
aimTo investigate the impacts of clinical features, pathology type, treatment strategies, and tumor stage on maternal and fetal outcomes in pregnant patients with pregnancy-associated CRC (pCRC).
methodsTo address this research gap, we analyzed the clinical and pathological characteristics of pCRC by collecting and evaluating clinicopathological data from 43 patients treated at the National Cancer Center/Cancer Hospital, Chinese Academy of Medical Sciences, between 1999 and 2023 using descriptive statistical methods.
resultsTreatment for pCRC was initiated with surgery and/or chemotherapy. Among 43 patients, 37 underwent surgery, including 21 radical resections (5 prenatal and 16 postpartum resections) and 16 palliative surgeries. Chemotherapy (with regimens such as CapeOx or FOLFOX4) was administered to 37 patients. Six advanced-stage patients received chemotherapy alone. The gestational outcomes among the patients varied. Specifically, 5 patients who were diagnosed in early pregnancy chose abortion. Additionally, in mid-pregnancy, 3 patients underwent abortion, 1 required induced labor, and 2 underwent cesarean delivery with healthy neonates. Among the 3 late-pregnancy diagnoses, 1 patient underwent induced abortion, 1 delivered
conclusionPatients with poorly differentiated tumors exhibited worse outcomes than those with moderately and highly differentiated tumors. Early-stage diagnosis and timely treatment significantly improved maternal survival and fetal outcomes in pregnant patients with CRC. Advanced tumor stages and delayed diagnosis were observed to be associated with poorer maternal prognoses and may require interventions that compromise fetal survival. Fetal outcomes depend on the pathological stage of the mother's cancer, the gestational age at diagnosis, and treatment strategies.
