Outline of Research at the Start

子宮頸癌根治的放射線治療において、強度変調放射線治療(intensity modulated radiotherapy: IMRT)による全骨盤照射(WP-IMRT)と、3次元治療計画画像誘導小線源治療(3D image-guided brachytherapy: 3D-IGBT)の併用で、本邦標準の低線量処方を行うプロトコルの臨床試験を実施する。線量体積ヒストグラム(DVH)パラメータの合算線量で治療結果を検討し、より定量的な形で本邦の低線量処方の有効性を明らかにする。

Outline of Final Research Achievements

Because of insufficient clinical data of definitive radiotherapy consisted of IMRT (no central shielding) and 3D-IGBT for Japanese patients, we conducted multi-institutional retrospective observational study to explore the feasibility and appropriate doses for Japanese cervical cancer patients. The study included 167 patients (T1+2 = 108, T3+4 = 59) from 8 Japanese institutions. The 2-year incidence of >=grade 3 proctitis/cystitis was 4%/1% for T1+2 and 10%/2% for T3+4. The 2-year local progression-free survival (LPFS) was 89% for T1+2 and 82% for T3+4. For T1+2, the 2-year LPFS for HR-CTV D90 >=68 Gy was 92% versus 67% for <68 Gy (log-rank; P = 0.019). For T3+4, the 2-year LPFS was 87% for HR-CTV <82 cm3 and 43% for >=82 cm3 (P = 0.0004). In conclusion, definitive radiotherapy consisting of no-CS-EBRT and 3D-IGBT was feasible for Japanese patients with cervical cancer. Dose de-escalation from the current global standards is suggested for patients with T1+2 disease.

Academic Significance and Societal Importance of the Research Achievements

本邦で遅れていた高精度放射線治療の強度変調放射線治療(IMRT)の子宮頸癌根治照射への適用に向けた研究の推進に寄与する。欧米の標準線量より低線量で腫瘍制御が可能な患者群が示唆されたことにより、日本人をはじめアジア人女性に対しより安全な低毒性治療が可能になることが期待される。
