Lateral pelvic lymph node metastasis is an important metastatic mode and a major cause of locoregional recurrence of mid-low rectal cancer. Recently, there is an East-West discrepancy in regard to the diagnosis, clinical significance, treatment and prognosis of lateral pelvic lymph node metastasis. In the West, lateral nodal involvement may represent systemic disease and preoperative chemoradiotherapy can sterilize clinically suspected lateral nodes. Thus, in many Western countries, the standard therapy for lower rectal cancer is total mesorectal excision with chemoradiotherapy, and pelvic sidewall dissection is rarely performed...

Background: Neoadjuvant chemotherapy followed by surgery (NAC-S) represents the standard treatment for patients with Stage II/III esophageal squamous cell carcinoma (ESCC) in Japan. Chemoradiotherapy (CRT) is performed in patients who refuse or have contraindications to surgery. However, randomized clinical trials that compare NAC-S with CRT have not been conducted. The aim of this study was to explore subgroups of patients undergoing CRT to identify those with survival outcomes potentially equivalent to NAC-S...

REVIEW
Alessandro Del Gobbo, Stefano Ferrero
We explain the state of the art of the immunohistochemical markers of response in rectal cancers treated with neoadjuvant medical therapies and its implication with prognosis. Neoadjuvant chemoradiotherapy is widely used to improve the outcome of patients with locally advanced rectal cancer, and the evaluation of the effects of medical therapy is to date based on histomorphological examination by applying four grading systems of response to therapy (tumor regression grade (TRG)). The need to identify immunohistochemical markers that could ensure a better assessment of response and possibly provide additional prognostic information has emerged...

AIM: A proportion of locally advanced rectal cancer patients who receive neoadjuvant chemoradiotherapy (NACRT) are still unresectable. This study was undertaken to assess the outcomes of giving additional chemotherapy to rectal cancer patients with unresectable disease after NACRT. METHODS: Patients with poor response to NACRT where mesorectal fascia was still involved on MRI and R0 resection was doubtful, received additional four cycles of chemotherapy with either CAPOX or FOLFIRINOX regimen, and the response was reevaluated with MRI and reassessed for surgical resection...

REVIEW

The treatment of locally advanced rectal cancer (LARC) has benefited from improved surgical techniques and from the implementation of neoadjuvant chemoradiotherapy (CRT), which have markedly decreased the rates of local recurrence. However, distant metastatic disease remains the most significant cause of death for these patients. Although adjuvant chemotherapy (ChT) after neoadjuvant CRT and definitive surgery is commonly recommended, the value of adjuvant systemic therapy remains less clear. Trials evaluating adjuvant ChT for rectal cancer have been handicapped by poor compliance rates and inconsistent survival results...

BACKGROUND: Neoadjuvant chemoradiotherapy (NCRT) for advanced rectal cancer (RC) is a well-evidenced therapy; however, some RC patients have no therapeutic response. Patient selection for NCRT so that non-responsive patients are excluded has been subjective. To date, no molecular markers indicating radiation sensitivity have been reported. METHODS: We irradiated six colorectal cancer (CRC) cell lines and identified HCT116 cells as radiation-sensitive and HCT15 and DLD-1 cells as radiation resistant...

INTRODUCTION: The inconvenience of using infusion therapies resulted in the development of capecitabine (CA), an oral fluoropyrimidine. In this meta-analysis, we evaluated 10 studies that compared the efficacy and safety of an oral CA-based regimen with those of a continuous infusion 5-fluorouracil (5-FU) regimen for neoadjuvant chemoradiotherapy in patients with rectal cancer. MATERIALS AND METHODS: The databases searched included Medline, Cochrane, EMBASE, and Google Scholar (until August 31, 2016)...
