It compared two TNT regimens: induction chemotherapy-chemoradiotherapy (INCT-CRT) and chemoradiotherapy-consolidation chemotherapy (CRT-CNCT). Depending on tumor response, patients were offered WW or surgery. The primary endpoint was disease-free survival (DFS), hypothesizing that patients who underwent TNT with selective WW would have improved DFS compared to historical rates. Secondary endpoints included organ preservation (OP) and overall survival, hypothesizing that differences between INCT-CRT and CRT-CNCT could indicate a superior regimen. Results demonstrated treatment of LARC with TNT and selective WW allows for OP in approximately half of patients without negatively impacting oncologic outcomes such as DFS. The data show that a CRT-CNCT regimen had higher rates of OP, lower rates of tumor regrowth, and similar DFS compared to INCT-CRT. Lastly, DFS does not differ between patients who undergo immediate TME versus TME after regrowth. Thus, patients treated with TNT who achieve a clinical complete response (cCR) can safely undergo WW with the potential for OP. Current research to improve TNT and enhance cCR will expand the utility of the WW approach, including the intensification of neoadjuvant chemotherapy (Janus trial), comparing short-course and long-course CRT prior to CNCT (ENSEMBLE and German trials), utilizing fluoropyrimidine-chemotherapy with and without oxaliplatin in the context of WW (CHOW trial), and exploring less invasive operative approaches for early-stage tumors (NEO and NEO-RT trials).</p></div><div><h3>Synopsis</h3><p>The OPRA trial demonstrates treatment of locally advanced rectal cancer using total neoadjuvant therapy with selective “watch-and-wait” allows organ preservation in approximately half of patients without negatively impacting oncologic outcomes.

This study evaluated extent of resection and surgical approach for SF adenocarcinoma and their respective outcomes.</p></div><div><h3>Methods</h3><p>Adults with stage I-III splenic flexure adenocarcinoma were identified in the National Cancer Database (2004–2020) and categorized by surgical management.</p></div><div><h3>Results</h3><p>Of 7412 patients, 4264 (58%) underwent extended colectomy (EC). The cohorts were overall similar, though more patients with stage I disease were managed with segmental colectomy (SC) (24% <em>vs.</em> 20%, p &lt; 0.01). Those undergoing EC had longer hospital stays (LOS) and greater odds of readmission. Use of robotic-assisted surgery was higher in SC (9% <em>vs.</em> 7%, p &lt; 0.01) and increased from 1% in 2010 to 24% in 2020. This approach was independently associated with a shorter LOS than open surgery. Despite a higher number of lymph nodes examined (median 18 <em>vs.</em> 16), EC and SC had similar nodal (both 37%, p = 0.95) and margin involvement (both 4%, p = 0.39). Five-year survival after EC and SC was similar (75% <em>vs.</em> 76%, p = 0.6). Patients undergoing robotic surgery had significantly lower odds of positive surgical margins and experienced an improved prognosis.</p></div><div><h3>Conclusions</h3><p>EC and SC were performed at similar rates for SF adenocarcinoma, while the use of robotic surgery increased over time. Neither extent of resection nor surgical approach significantly impacted oncologic outcomes. These data indicate that surgical decision-making should be balanced between tumor- and patient-specific considerations, morbidity of extended colectomy, and surgeon preference.</p></div><div><h3>Synopsis</h3><p>In a national cohort of splenic flexure cancers, segmental and extended colectomy were associated with comparable rates of negative margins, nodal involvement, and survival. Robotic assist increased over time without impacting oncologic outcomes. Surgical procedure and approach should thus be tailored to clinical condition and surgeon preference.</p></div>","PeriodicalId":101191,"journal":{"name":"Surgical Oncology Insight","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-03-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2950247024000483/pdfft?md5=d46c68fb981bdfa682b015c20a279c6d&pid=1-s2.0-S2950247024000483-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140122502","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
