Preoperatory FLOT Regimen for Gastroesophageal Cancer and Renal Function: A New Onco-Nephrological Perspective.

BACKGROUND

The FLOT regimen, a combination of fluorouracil, leucovorin, oxaliplatin, and docetaxel, is a standard treatment for gastric and esophagogastric junction cancers, but concerns exist about its potential renal toxicity. The exact prevalence and severity of renal toxicity need to be well documented, and this knowledge gap could impact the optimal use of the FLOT regimen in clinical practice. We aimed to evaluate the renal toxicity profile of the FLOT regimen with a specific focus on acute kidney disease (AKD) onset in a real-life setting and explore associated risk factors.

METHODS

We conducted a multicenter retrospective study involving 96 patients treated with preoperatory FLOT. The incidence of AKD and potential risk factors were identified.

RESULTS

AKD occurred in 3 patients (incidence rate of 0.0122 cases/month of follow-up). Oral antidiabetic agents and prostate hypertrophy emerged as significant predictors of AKD.

CONCLUSION

AKD is uncommon in patients treated with the preoperatory FLOT regimen. Our findings highlight the importance of diligent renal function monitoring and appropriate preventive strategies in patients undergoing FLOT treatment. These results encourage the conduction of further studies and clinical experience in larger populations and patients with lower baseline estimated glomerular filtration rate.
