Chemoradiation in locally advanced Ca Cx: Effect on NGAL levels

Area of Science:

• Oncology
• Biochemistry
• Medical Biomarkers

Background:

• Neutrophil gelatinase-associated lipocalin (NGAL) is implicated in various cancers, potentially promoting cell proliferation by suppressing tumor suppressor genes like p53.
• Research on the role of NGAL in cervical cancer (Ca Cx) remains limited.

Purpose of the Study:

• To investigate the relationship between serum NGAL levels and locally advanced cervical cancer.
• To assess changes in NGAL levels following standard chemoradiation therapy in Ca Cx patients.

Main Methods:

• Serum NGAL levels were measured using ELISA in 30 locally advanced Ca Cx patients at diagnosis and 3 weeks post-chemoradiation.
• Patients received either brachytherapy or external beam radiotherapy (EBRT).
• Statistical analysis was performed using Student's paired t-test.

Main Results:

• No significant overall change in NGAL levels was observed before and after treatment, or when stratified by stage, grade, or response.
• NGAL levels increased significantly with treatment durations of ≥8 weeks (P=0.040) and decreased significantly with durations <8 weeks (P=0.0052).
• A significant increase in NGAL was noted post-treatment for patients receiving EBRT and supplementary radiotherapy (P=0.019), unlike those receiving EBRT + brachytherapy (P>0.05).

Conclusions:

• Treatment duration and modality are critical in Ca Cx, with shorter durations correlating to better outcomes and lower NGAL levels.
• NGAL may serve as a potential biomarker in cervical cancer.
• Further research is necessary to validate NGAL's role as a biomarker in Ca Cx.
