背景および目的:
寛骨臼(寛骨臼周囲)を含む腫瘍切除後の再建には、さまざまな方法がある。本研究の目的は、寛骨臼周囲の腫瘍切除範囲および再建方法別に機能的転帰と合併症率を解析することであった。
BACKGROUNDS AND OBJECTIVES: Following tumor resection involving the acetabulum (periacetabular), various methods of reconstruction exist. The objective of this study was to analyze functional outcomes and complication rates by extent of periacetabular tumor resection, as well as by method of reconstruction.
方法:
1993年から2018年までに単一施設で原発性骨盤骨腫瘍に対する骨盤周囲切除術を受けた患者23例を対象とした。合併症は記録され、機能的転帰はMusculoskeletal Tumor Society(MSTS)スコアリングシステムを用いて評価された。
METHODS: Twenty-three patients underwent periacetabular resection for a primary pelvic bone tumor from 1993-2018 at a single institution. Complications were documented and functional outcomes were assessed using the Musculoskeletal Tumor Society (MSTS) scoring system.
結果:
平均年齢は42.8±22.6歳であった。平均追跡期間は107±75ヵ月であった。MSTSスコアは、アログラフト再建患者(80.2%)で最も高く、サドル再建患者(38.0%)で最も低かった。MSTSスコアは、II型骨周囲切除単独の患者では、II型+追加切除と比較して高かった(78.6% vs 60.3%;P=.019)。合併症はII型骨周囲切除のみの患者では75% vs 28.6%;P=.036)であった。合併症は全移植片再建術後が最も高く(78%)、再建を伴わない半月板切除術後が最も低かった(20%)。
RESULTS: Mean age was 42.8 ± 22.6 years. Mean follow-up was 107 ± 75 months. MSTS scores were highest in patients with allograft reconstruction (80.2%) and lowest in saddle reconstruction (38.0%). MSTS scores were higher in patients with Type II periacetabular resection alone compared with Type II + additional resection (78.6% vs 60.3%; P = .019). Complications were lower in patients with Type II periacetabular resection alone (75% vs 28.6%; P = .036). Complications were highest following allograft reconstruction (78%) and lowest following hemipelvectomy without reconstruction (20%).
結論:
アログラフト/APCまたは非鞍部金属再建を受けた患者は、機能的転帰スコアが最も高かったが、再建を行わない場合に比べて合併症率も高かった。臼蓋周囲に加えて腸骨および/または恥骨を切除した患者は、機能的転帰スコアが低く、合併症のリスクが高かった。
CONCLUSION: Patients who underwent allograft/APC or nonsaddle metallic reconstruction experienced the highest functional outcome scores, but also sustained a higher complication rate than patients with hemipelvectomy without reconstruction. Patients with resection of ilium and/or pubis in addition to the periacetabular region had lower functional outcome scores and higher risk for complication.
