Is Weight Loss During Chemotherapy for Pancreatic Cancer Prognostic?

Résumé fourni par la source

Background Predicting poor survival outcomes early in palliative chemotherapy is important to the timing of palliative care. Weight loss during chemotherapy if prognostic would lead to early palliative care. Method We collected demographics, stage, chemotherapy, chemotherapy cycles, weight, healthcare utilization, comorbidities (Charleson Comorbid Index), tumor markers, and weight changes over 60 days. We defined 3 groups of patients: 1. Weight gain to <.5% weight loss, 2. Weight loss< 2% and 3. Weight loss of >2%. A Chi-square test assessed differences in weight during treatment. Time-to-event analysis was expressed in a Kaplan Meier curve. Results 93 individuals died of pancreatic cancer in 2018 and 2019. The median age was 71.2 years. Forty-three had stage I and II, 40 stages III and IV cancers, and 10 had unknown stages. Most received FOLFIRINOX and gemcitabine/nab-paclitaxel chemotherapy. Thirty-six gained to lost < .5% during chemotherapy,8 lost < 2% and 49 patients lost > 2% of their weight. Mortality was available in 55 of 93 patients. Median survival was 16.6 months in those with weight gain to < .5% weight loss, 17.28 months for those with < 2% weight loss, and 20.5 months for those with > 2% weight loss ( P = .42). Discussion Weight loss over 60 days did not predict a poor prognosis in this small retrospective study; larger prospective studies may clarify the prognostic importance of weight loss during chemotherapy. Conclusion In this small retrospective study, weight loss over 60 days did not predict poor survival.
