[Analysis of factors affecting the prognosis of patients with pancreatic cancer patients with obstructive jaundice].

Objective: Objective To analyze the relationship between the survival outcomes of pancreatic cancer patients with obstructive jaundice and various clinical and pathological factors. Methods: A case series study was conducted, where clinical data from pancreatic cancer patients with obstructive jaundice, who were admitted to the Cancer Hospital of Tianjin Medical University between March 2022 and May 2023, were retrospectively gathered. Factors potentially affecting patient prognosis were initially analyzed using univariate analysis, followed by multivariate analysis using the Cox regression model for selected factors. A P-value of less than 0.05 was deemed statistically significant. Results: The study included 104 patients, comprising 69 males and 35 females, with a median age of 62 years (ranging from 38 to 85 years). Of these, 76 patients (73.1%) were followed until death, with a median survival time of 8.9 (6.2,11.5) months. The number of deaths versus surviving cases at 6 and 12 months were 20/75 and 64/14, respectively, resulting in estimated survival rates of 79.6% and 22.8%. Univariate analysis identified factors such as weight loss, primary site, TNM stage, liver metastasis, number of organs with tumor, stage at which jaundice appeared, CA19-9 levels, albumin levels, and D-dimer levels as significant in influencing prognosis (all P<0.05). Multivariate analysis revealed TNM stage, number of organs with tumor, method of jaundice treatment, albumin levels, and D-dimer levels as independent prognostic factors (all P<0.05). Conclusion: In pancreatic cancer patients presenting with obstructive jaundice, close monitoring of weight loss, primary site, TNM stage, liver metastasis, number of organs with tumor, the timing of jaundice occurrence, method of jaundice treatment, CA19-9, albumin, and D-dimer levels is crucial, as these factors may significantly impact the patient's survival and prognosis.
