Cervical Cancer

[edit | edit source]
  • UC San Diego
    • 2011 PMID 20400238 -- "Normal tissue complication probability modeling of acute hematologic toxicity in cervical cancer patients treated with chemoradiotherapy." (Rose BS, Int J Radiat Oncol Biol Phys. 2011 Mar 1;79(3):800-7. Epub 2010 Apr 17.)
      • Retrospective. 81 patients treated with concurrent chemo-RT for cervical cancer. DVHs of bone marrow in pelvic field evaluated
      • Outcome: V10 <95% and V20 <76% correlated with lower acute G3+ hematologic toxicity. V10 (25% vs 69%, SS) and V20 (22% vs 58%, SS)
      • Conclusion: Acute hematologic toxicity increases with increasing pelvic bone marrow volume irradiated
