Evaluating Surgical Outcomes and Survival in Colon Cancer Patients Over 80 Years Old.
Article in Cureus, 2024. 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
BACKGROUND AND
aimsIn the context of an increasing older population, knowing the surgical outcomes of older patients is of paramount importance to define a comprehensive strategy for colon cancer treatment in these patients. This study aimed to analyze the surgical outcomes and survival of patients over 80 years old undergoing surgery for colon cancer. MATERIALS AND
methodsThis is an observational retrospective longitudinal study of patients over 80 years old with colon cancer diagnosis who underwent surgery for this condition, between 2018 and 2021, in a Portuguese hospital. Demographic and clinical features were characterized. Kaplan-Meier method was used for survival analysis.
resultsOut of 90 patients in the study, 41.1% were female. The majority (56.7%) had an Eastern Cooperative Oncology Group (ECOG) performance status of 1 or 0, with a median Charlson Comorbidity Index of 7.0. Tumors were primarily located in the right colon (52.2%) and sigmoid colon (25.6%), with most patients having stage II (35.6%) or stage III (25.5%) disease. Elective surgeries accounted for 73% of procedures, and 80.0% had curative intent, with laparoscopic surgery performed in 66.7% of cases. Only 8.3% of those undergoing curative-intent procedures received adjuvant chemotherapy. Emergent admissions were associated with more advanced cancer stages, higher rates of palliative intent procedures (45.8% versus 10.6%, p < 0.001), and more open surgeries (75.0% versus 9.1%, p < 0.001) when compared to elective procedures. Postoperative mortality was higher in the emergent group (20.8% versus 10.6%), though there was no association between the type of admission and postoperative complications. Median overall survival for all patients was 36.7 (95% CI 28.1 to 45.3) months, with significant differences between curative-intent and palliative surgeries (median of 39.8 (95% CI 32.6 to 47.0) versus 10.6 (95% CI 0.67 to 20.5) months, p = 0.015). The elective group of patients had significantly better overall survival compared to the emergent group (median of 36.7 (95% CI 30.7 to 42.7) versus 11.9 (95% CI 6.0 to 17.8) months, p = 0.01). Among the patients who underwent curative-intent procedures, there were no significant differences in overall or disease-free survival between elective and emergent groups.
conclusionsDespite the increased complexity of managing older patients, particularly in emergent cases, these findings emphasize the importance of elective, curative-intent surgeries to optimize overall survival. Effective treatment strategies and perioperative management tailored to this age group are essential for improving surgical outcomes and extending survival in elderly colon cancer patients.
