Efficacy and Feasibility of Adding Induction Chemotherapy to Neoadjuvant Chemoradiation in Locally Advanced Rectal Cancer: A Phase II Clinical Trial.

This study aimed to investigate the efficacy and feasibility of adding induction chemotherapy to neoadjuvant CRT in locally advanced rectal cancer. METHODS: This phase-II clinical trial included 54 patients with newly diagnosed, locally advanced (clinical T3-4 and/or N1-2, M0) rectal cancer. All patients were treated with 3 cycles of preoperative chemotherapy using the XELOX (capecitabine + oxaliplatin) regimen before and after a concurrent standard long course of CRT (45-50.4 Gy) followed by standard radical surgery. Pathologic complete response (PCR) rate and toxicity were the primary and secondary endpoints, respectively. RESULTS: The study participants included 37 males and 17 females, with a median age of 59 years (range, 20-80 years). Twenty-nine patients (54%) had clinical stage-II disease, and 25 patients (46%) had clinical stage-III disease. Larger tumor size (P = 0.006) and distal rectal location (P = 0.009) showed lower PCR compared to smaller tumor size and upper rectal location. Pathologic examinations showed significant tumor regression (6.1 ± 2.7 cm vs. 1.9 ± 1.8 cm, P

Conclusions: In Western patients with Stage III low rectal cancer, there is a trend toward worse LR rate and DFS rates in LLN+ patients compared to similarly staged LLN− patients. These results suggest that LLN+ patients may currently not be treated optimally with nCRT alone, and the addition of LLND requires further consideration.

AbstractBackgroundIn the USA, most patients with clinical stage II/III rectal cancer receive neoadjuvant chemoradiation (chemo/XRT) over 5 –6 weeks followed by a 6–10-week break before proctectomy. As chemotherapy is delivered at radio-sensitizing doses, there is essentially a 3-month window during which potential systemic disease is untreated. Evidence regarding the utility of restaging patients prior to proctectomy is limited.MethodsPubMed, Scopus, Web of Science, and the Cochrane Library were searched for studies evaluating the utility of restaging patients with rectal cancer after completion of long-co...

AbstractPurpose of ReviewContrarily to what happens with rectal cancer, the role of magnetic resonance imaging (MRI) in the assessment of colon cancer has been limited. However, we may witness a ‘paradigm shift’ in the future. Classically, colon cancer has been assessed by computed tomography (CT) which is considered the workhorse for evaluating this neoplasm as it provides insights not only about local and regional disease as well as about distant metastases. However, as the accuracy o f CT is somewhat limited, recent reports about the use of MRI in colon cancers have been published. In this review we will ass...
