Abstract This retrospective study evaluated outcome with regard to procedure, local control, and survival after curative surgical resection with and without preoperative radiotherapy for local pelvic recurrence. A total of 58 consecutive patients with local pelvic recurrence of rectal cancer after previous curative resection for primary tumors were reviewed. Of these, 36 underwent both initial resection and follow-up in our department; the remaining 22 had initial surgery and follow-up elsewhere. Of the 58 patients 27 underwent curative re-resection, 9 had palliative resection, and 22 were treated by conservative therapy. Among the 27 patients with curative resection 17 received preoperative radiotherapy (40 Gy) plus surgery and 10 surgery only. No patients were lost to follow-up; median follow-up time was 36.3 months. The overall rate of curative resection was 46.6%: 55.6% in our own follow-up group and 31.8% in the others. With regard to surgical procedure, abdominoperineal resection (APR) with or without sacral resection was standard following previous low anterior resection, and total pelvic exenteration (TPE) with or without sacral resection was common following APR. There was a high incidence of morbidity (71.4%) after TPE. Re-recurrence was observed in 12 (44.4%) after curative re-resection. There was local re-recurrence in 6 (22.2%). The local re-recurrence rate was 11.8% (n = 2) with radiotherapy plus surgery, and 40.0% (n = 4) with surgery alone. The estimated 5-year survival following curative re-resection was 45.6% (61.2% with radiotherapy plus surgery, 29.6% with surgery alone). Both survival and local control with radiotherapy plus surgery tended to be better than with surgery alone. Thus, in selected patients pelvic local recurrence of rectal cancer can be re-resected curably by APR or TPE (with or without sacral resection) combined with preoperative radiotherapy.Résumé Le but de cette étude rétrospective est dévaluer le devenir des interventions chirurgicales, le contrôle local et la survie après résection chirurgicale curative avec ou sans radiothérapie pré-opératoire de récidives pelviennes locales. Méthodes: cinquante-huit patients consécutifs porteurs dune récidive pelvienne locale dun cancer du rectum, après résection curative pour tumeur primaire, ont été revus. Ces patients ont été classés dans un groups soumis à un follow-up (36 patients) et les autres (22 patients). Les patients du groupe follow-up avaient subi la résection initiale et le suivi post-opératoire dans notre département. Vingtsept des cinquante-huit patients ont subi une ré-résection curative; neuf ont subi une résection palliative et vingt-deux ont été traités par un traitement purement conservateur. Chez les vingt-sept patients avec résection curative, dix-sept ont reçu de la radiothérapie pré-opératoire (40 Gy)– XRT+ chirurgie et 10 patients qui nont subi quun geste chirurgical isolé. Aucun patient na été perdu de vue. Le temps moyen de survie est de 36,3 mois. Résultats: la moyenne de résection curative est de 46,6% : 55,6% dans le groupe avec follow-up et 31,8% dans le reste des cas. En ce qui concerne le procédé chirurgical, lamputation abdomino-périnéale (APR) avec ou sans résection sacrée est loption standard faisant suite à une résection antérieure, et lexentération pelvienne totale (TPE) avec ou sans résection sacrée a été réalisée fréquemment après une amputation abdomino-périnéale. Après une exentération pelvienne totale, la morbidité est élevée (71,4%), une deuxième récidive survient chez 12 malades (44,4% après une re-résection curative). Une deuxième récidive survient chez 6 patients (22,2%). Le taux de re-récidive locale est de 11,8% (2 patients) chez ceux qui ont subi une radiothérapie per-opératoire + chirurgie et de 40% (4 patients) dans le groupe ayant subi la chirurgie seule. La survie à 5 ans estimée après re-résection curative est de 45,6% (61,2% dans le groupe avec radiothérapie et chirurgie, 29,6% dans le groupe avec chirurgie seule). La survie et le contrôle local chez les patients ayant sub une radiothérapie pré-opératoire + chirurgie est meilleure que le groupe ayant subi une chirurgie seule. Conclusion: dans un groupe de patients sélectionnés, une récidive pelvienne locale du cancer peut être re-réséquée de manière curative par amputation périnéale ou exentération pelvienne totale (avec ou sans résection sacrée) en combinaison avec une radiothérapie pré-opératoire.

Background and aimsThis study examined rectal cancers with lateral lymph node (LN) metastases and whether lateral lymph node dissection (LLD) with or without preoperative chemo-radiotherapy (XRT) benefits patients with rectal cancer.Patients and methodsA total of 452 consecutive cases of curatively resected pT2, pT3, and pT4 middle to lower rectal cancers were retrospectively analyzed. Of these, 265 patients underwent curative LLD and 155 XRT. Data were evaluated with respect to the cumulative percentage of survival.ResultsLateral LN metastases were identified in 7.7% of patients. Of the pT3/pT4 extraperitoneal cancer patients 13.5/18.8% had lateral LN metastases. In the treatment of middle rectal cancers and pT2 extraperitoneal cancers LLD either with or without XRT did not improve survival rate. For the treatment of pT3/pT4 extraperitoneal tumors prior to the introduction of total mesorectal excision (TME) in 1994 LLD plus XRT yielded significantly better survival and local control than conventional surgery without LLD or XRT, although LLD alone did not improve either survival or local recurrence rates. Since 1995 TME with or without subsequent LLD has yielded favorable results for the treatment of extraperitoneal tumors.ConclusionFor the treatment of middle rectal cancers and pT2 extraperitoneal cancers LLD either with or without XRT does not improve survival rate. For pT3/pT4 extraperitoneal tumors, which are associated with a high incidence of lateral node metastasis, combining treatment modalities such as TME followed by LLD or XRT followed by TME may be considered.

はじめに: 上部胃癌の手術術式の選択にあたり, 噴門側胃切除が至適術式として採用できるか否かをリンパ節郭清の程度も含め, 壁深達度とリンパ節転移の状況に基づき検討した. 方法: 1973年から2005年に行われたH0P0M0のU領域, 初発単発胃癌切除例401例を対象とし, No.4d, 5, 6, 10, 11のリンパ節の転移の特徴, 臨床病理組織学的因子につき検討した. 結果: 深達度SSまでのNo.10転移例は郭清例126例中5例 (4.0%) であり, 全例病変の占居部位は胃上部左半にあった. 4例は腫瘍径が40mm以上であり, 1群リンパ節転移を伴っていた. No.11転移例は郭清例126例中8例 (6.3%) で, そのうちNo.11dの転移例は3例のみであり, 全例病変の占居部位は胃上部左半にあり, 1群リンパ節転移を伴っていた. そのうち, 2例は腫瘍径が40mm以上であった. No.4d転移例は郭清例189例中3例 (1.6%) で, 全例腫瘍径は40mm以上, 病変の占居部位は胃上部左半にあった. No.5, 6リンパ節転移例は認めなかった. 深達度SE, SIではそれぞれのリンパ節転移率は高率となる傾向であった. 結語: 深達度SSまでで占居部位が小彎に限局, あるいは腫瘍径が40mm未満もしくは1群リンパ節転移を認めない場合, No.4d, 5, 6, 10, 11dのリンパ節転移例はごくまれであった. したがって, 上部胃癌では上記の条件を満たす場合, 噴門側胃切除術, D1+No.7, 8a, 9, 11pのリンパ節郭清は至適術式と考えてよいと思われた.

直腸癌局所再発の予後はきわめて不良である.直腸癌治癒切除後の局所再発の早期発見を目的とした新たな経過観察法を考案し, その有用性について検討した.教室での過去8年間の直腸癌治癒切除症例175例を対象とし, 各症例を臨床病理学的因子により再発のhighrisk group, intermediate riskgroup, low rish groupに分類して経過観察を行った.経過観察の検査項目では理学所見, 腫瘍マーカーにultrasonography (US), computed tomography (CT), magnetic resonance imaging (MRI), およびCT下生検を組合わせ, riskgroup別のプロトコールにより実施した.175例中27例 (15.4%) に局所再発が診断され, この27例中20例はhigh risk group, 7例がintermediate risk groupの症例であった.27例中12例 (44.5%) に治癒的再切除が施行され, この経過観察の有用性が認められた.直腸癌術後の再発のrisk group別の経過観察では, 治癒的再切除の可能な局所再発の早期発見が期待できると考えられた.
