A major cohort study published in JAMA Oncology challenges the common practice of combining chemotherapy with radiotherapy after surgery in patients with intermediate-risk cervical cancer, finding no survival benefit over radiotherapy alone. 


🎯 Study Objective 

To evaluate whether adjuvant chemoradiotherapy (CRT) offers superior overall survival compared to radiotherapy (RT) alone following radical hysterectomy in stage IB cervical carcinoma. 


🧪 Methods 


  • Data source: National Cancer Database (2010–2019) 
  • Population: 1,116 patients with intermediate-risk cervical cancer 
  • Design: Retrospective cohort with propensity score matching 
  • Final matched cohort: 868 patients (CRT vs RT) 

👩‍⚕️ Patient Profile 


  • Mean age: 47 years 
  • 43.5% received chemoradiotherapy 
  • Chemotherapy more commonly given in:  
  • Adenocarcinoma 
  • Larger tumors 

📊 Key Findings 


  • 5-year survival:  
  • CRT group: 87% 
  • RT group: 87% 
  • Hazard Ratio (HR): 0.85 (P = 0.38) → No statistically significant difference 
  • Subgroup analysis: No survival advantage based on tumor size or histology 

🩺 Clinical Implications 

  • No clear benefit of adding chemotherapy in this population 
  • Suggests the need for treatment de-escalation in intermediate-risk patients 
  • Promotes evidence-based treatment selection to avoid overtreatment and reduce unnecessary toxicity 

🔍 Looking Ahead 


  • Encourages further research to refine adjuvant treatment protocols 
  • Highlights the importance of individualized care decisions 
  • Supports re-evaluation of current guidelines in light of non-superior outcomes 

Forma 


🧠 Takeaway: In intermediate-risk cervical cancer, radiotherapy alone may be sufficient, sparing patients from the added burden of chemotherapy without compromising survival.
