Abstract
BACKGROUND: Cervical cancer is a formidable global health issue, particularly affecting women in lower-middle-income countries with little or no access to preventative vaccines, screening programs, and treatment modalities. The case report presents a unique case of a large cervical cancer achieving complete response (CR) with concurrent chemoradiotherapy (CCRT), highlighting the effectiveness of this treatment approach even in advanced stages and underscoring the importance of adaptive radiotherapy (RT) in optimizing patient outcomes. CASE SUMMARY: We present the case of a 53-year-old woman who presented with four years of abnormal vaginal bleeding and was found to have p16-positive, moderately differentiated cervical squamous cell carcinoma. The tumor measured 14 cm × 12 cm × 8 cm, the largest size reported in the literature to achieve CR with CCRT. Despite this monumental feat, the patient remained disease-free and is currently on follow-up for 2 years; however, she continued to suffer from substantial morbidity caused by a vesicovaginal fistula and hydronephrosis, underscoring the continuing impact of cervical cancer on quality of life. CONCLUSION: In this case report, we highlight the effectiveness of CCRT in achieving CR, even in cases of bulky cervical cancer, with adaptive RT offering a customized strategy to improve patient outcomes. We also emphasize the necessity for multidisciplinary team discussions and highlight the need for strategies to mitigate treatment-related toxicities and long-term complications.
