Outline of Research at the Start

本研究の主眼は、腎盂尿管内粘膜を起源とする腎盂尿管癌および術後膀胱内再発後膀胱癌、そしてMIBC進展症例に至るまでの豊富な臨床検体を利用し、癌細胞集団内に存在する分子細胞学的特徴とその連続性を明らかにすることで癌不均一性克服の一助とし、新規バイオマーカーの探索と同定を行うことで臨床現場に有用な癌再発進展系統樹を作成する事である。

Outline of Final Research Achievements

Postoperative bladder recurrence in renal pelvic and ureteral cancer, sometimes progressing to MIBC, poses challenges. This study tracks molecular characteristics of primary cancer and bladder recurrences. Among 214 patients post-nephroureterectomy, 92 had intravesical recurrence. CK20 and FGFR3 were predictive markers for recurrence. FGFR3 positivity was higher (60.9%) in recurrence cases. MIBC progression was associated with elevated p53 mutant protein expression. Renal pelvic and ureteral cancers tend to recur intravesically, especially luminal-papillary types with CK20 and FGFR3 positivity. Recurrent bladder cancer inherits molecular features from the primary tumor, with additional p53 mutant protein expression linked to muscle invasion.

Academic Significance and Societal Importance of the Research Achievements

これまで腎盂尿管癌患者の膀胱内再発リスク因子において、臨床病理学的因子の報告は多数行われてきたが、分子サブタイプを加えた再発リスク因子に関する知見は皆無であった。
本研究から、CK20やFGFR3などの分子マーカーが膀胱内再発の予測因子となることが示されたこと、更にはp53変異蛋白の存在がMIBCへの進展と関連していたことから、分子サブタイプ別病理学的評価は、再発進展リスクの高い患者に対する治療方針の決定に重要な意義をい持つと考えている。また、将来的には腎盂尿管癌や膀胱内再発後患者における革新的創薬研究に寄与すると考える。
