Phase II randomised trial of chemoradiotherapy with FOLFOX4 or cisplatin plus fluorouracil in oesophageal cancer

International audienceBackground: Concurrent chemoradiotherapy is a valuable treatment option for localised oesophageal cancer (EC), but improvement is still needed. A randomised phase II trial was initiated to assess the feasibility and efficacy in terms of the endoscopic complete response rate (ECRR) of radiotherapy with oxaliplatin, leucovorin and fluorouracil (FOLFOX4) or cisplatin/fluorouracil. Methods: Patients with unresectable EC (any T, any N, M0 or M1a), or medically unfit for surgery, were randomly assigned to receive either six cycles (three concomitant and three post-radiotherapy) of FOLFOX4 (arm A) or four cycles (two concomitant and two post-radiotherapy) of cisplatin/fluorouracil (arm B) along with radiotherapy 50 Gy in both arms. Responses were reviewed by independent experts. Results: A total of 97 patients were randomised (arm A/B, 53/44) and 95 were assessable. The majority had squamous cell carcinoma (82%; arm A/B, 42/38). Chemoradiotherapy was completed in 74 and 66%. The ECRR was 45 and 29% in arms A and B, respectively. Median times to progression were 15.2 and 9.2 months and the median overall survival was 22.7 and 15.1 months in arms A and B, respectively. Conclusion: Chemoradiotherapy with FOLFOX4, a well-tolerated and convenient combination with promising efficacy, is now being tested in a phase III trial

Relevance of Procalcitonin Levels as a Marker of Severity and Predictor of Mortality, Initiation and Duration of Antibiotics in Patients Admitted with Acute Pancreatitis: A Retrospective Cohort Study

Through this study, we are searching for any possible correlation between serum procalcitonin levels and the severity of acute pancreatitis (included acute on chronic cases) to determine whether procalcitonin levels can predict a benefit from antibiotic therapy in acute pancreatitis.Methods: This is a retrospective cohort study involving patients with acute pancreatitis and acute on chronic pancreatitis. We included all hospitalized patients admitted to Kern Medical from January 2020 to October 2022 with a diagnosis of acute pancreatitis in a consecutive manner. The primary outcome studied was mortality related to the pancreatitis episode. Logistic regression was used to control numerous confounders.Results: Based on univariate analysis of procalcitonin, we found starting antibiotics on the day of admission statistically significant. We also found the median differences in mortality to be mildly significant (difference = 0.79, p = 0.0640) based on procalcitonin values. In a multivariate analysis of ln(procalcitonin), we found lipase (p = 0.0249), duration of antibiotics (p = 0.0009), multi-organ failure (p = 0.0045) to be statistically significant, and lactate being mildly significant in the multivariate model (p = 0.0643).Conclusion: The procalcitonin level can predict the initiation of antibiotics, duration of antibiotics, multi-organ failure, and mortality in patients with acute pancreatitis.Keywords: procalcitonin, pancreatitis, acute pancreatiti
