Sepsis surveillance in patients with head-and-neck cancer undergoing chemo-radiation.

Background: The infection rate among patients with head-and-neck cancer (HNC) undergoing chemoradiotherapy (CRT) is approximately 19%, with sepsis-related death ranging from 3-9%. A previous study at our institute found a 12% sepsis-related death rate in HNC patients during CRT. The objective of this study is to investigate the utilization of sepsis surveillance and early intervention in reducing the occurrence of sepsis-related deaths in locally advanced HNC patients receiving CRT.

Methods: This retrospective analysis examined 54 patients with locally advanced HNC undergoing CRT who underwent sepsis surveillance between January 2018 and December 2021. The study recorded the utilization of oral and intravenous antibiotics, G-CSF, early admissions and their reasons, and the incidence of early mortality. Data analysis was conducted using SPSS v.24 software.

Results: Twenty-one (38.9%) patients were prescribed oral antibiotics, and 14 (25.9%) received G-CSF on an outpatient basis. Twenty-nine (54%) patients required hospital admission. Among the admitted patients, 28 (96%) received intravenous antibiotics, and G-CSF was administered in 18 (62%) patients. In 8 cases, antibiotic treatment was intensified due to persistent fever and deteriorating neutropenia. The median time for receiving antibiotics and G-CSF after starting CRT was 5th week (range: 3-8 weeks). Five patients required readmission. Only one patient succumbed to sepsis. Among the 54 patients, 48 (89%) completed the scheduled RT, while 14 (25.9%) received all 6 cycles of chemotherapy.

Conclusion: Sepsis surveillance and the prompt use of antibiotics and G-CSF, along with early hospitalization, when necessary, reduces the occurrence of sepsis-related early deaths in HNC patients undergoing CRT.
