PURPOSE: To compare distant metastasis (DM) in locally advanced rectal cancer (LARC) patients treated with neoadjuvant chemoradiotherapy (nCRT) and surgery alone, and to develop a predictive nomogram for DM following nCRT. METHODS: Propensity-scoring match analysis was performed to compare DM in LARC treated with nCRT (n = 375) and surgery alone (n = 375). Cox regression was performed to identify predictors of DM following nCRT. A nomogram was developed and validated by internal (n = 425) and external validation (n = 97)...

Among the subsets of tumor-infiltrating lymphocytes (TILs), activated cytotoxic T lymphocytes (granzyme B(+)) have an antitumor effect, while regulatory T lymphocytes [forkhead box P3 (Foxp3)(+)] suppress the antitumor immune response. The aim of the present study was to investigate the possible associations between TIL subsets and survival outcomes in patients with left-sided pancreatic ductal adenocarcinoma (PDAC). From January 2000 to December 2008, 30 patients who underwent curative distal pancreatectomy without neoadjuvant chemoradiotherapy due to left-sided PDAC were enrolled in the present study...

Rectal cancer patients receiving neoadjuvant chemoradiotherapy (NCRT) are currently classified using the same Tumor-Node-Metastasis staging system as those patients without NCRT. We determined whether the combination of tumor treatment response (TRG) and ypT stage more accurately assesses primary tumors in rectal cancer after NCRT. We analyzed data from 329 rectal cancer patients treated with NCRT followed by radical resection. Cox proportional hazards models were used to evaluate the effects of different staging parameters on disease-free survival (DFS)...

BACKGROUND Increasing evidence suggests that cancer-associated inflammation is associated with poorer outcomes. The neutrophil-to-lymphocyte ratio (NLR), considered as a systemic inflammation marker, is thought to predict prognoses in colorectal cancer. In this study, we explored the association between the NLR and prognoses following neoadjuvant chemoradiotherapy (CRT) for locally advanced rectal cancer (LARC). MATERIAL AND METHODS From February 2002 to December 2012, a group of 202 patients diagnosed with LARC and receiving neoadjuvant CRT followed by radical surgery was included in our retrospective study...

BACKGROUND: The long-term survival benefit of concurrent neoadjuvant chemoradiotherapy in patients with resectable esophageal cancer remains controversial. In the present study, we conducted a meta-analysis to assess these effectiveness. METHODS: We searched for most relevant studies published up to the end of August 2016, using Pubmed and web of knowledge. And additional articles were identified from previous meta-analysis. The hazard ratio (HR, for overall survival and progression free survival) or risk ratio (RR, for R0 resection) with its corresponding 95 % confidence interval (CI) were used to assess the pooled effect...

BACKGROUND AND AIMS: Laparoscopic resection is a well-established approach for colorectal cancer surgery. In patients with rectal cancer treated by neoadjuvant chemoradiotherapy, it may be difficult to identify a clear safety margin for endostapling and subsequent anastomosis. We designed an innovative technical approach to assist colorectal anastomosis in these patients. TECHNIQUE: A four-trocar laparoscopic approach is used. After exploration of the abdominal cavity, the left colic flexure is completely mobilized...

Esophageal cancer has a poor prognosis and high mortality rate, with an estimated 16,910 new cases and 15,910 deaths projected in 2016 in the United States. Squamous cell carcinoma and adenocarcinoma account for more than 95% of esophageal cancers. Squamous cell carcinoma is more common in nonindustrialized countries, and important risk factors include smoking, alcohol use, and achalasia. Adenocarcinoma is the predominant esophageal cancer in developed nations, and important risk factors include chronic gastroesophageal reflux disease, obesity, and smoking...

BACKGROUND/PURPOSE: The parameters to predict histological response to neoadjuvant therapy remain controversial in borderline resectable pancreatic carcinoma (BRPC). METHODS: Twenty-four patients who underwent diffusion-weighted magnetic resonance imaging (DW-MRI) prior to expected neoadjuvant chemo/chemoradiotherapy and surgery were reviewed retrospectively. Analyses for correlation between percent tumor cell destruction and the following was performed to investigate the parameter and cut off value: tumor size, whole tumor apparent diffusion coefficient (ADC) value of DW-MRI, maximum standardized uptake value of (18) F-fluorodeoxyglucose positron emission tomography, carbohydrate antigen 19-9, and their change ratios...

OBJECTIVE: The aim of the study was to investigate the association between p53, SOX2, and CD44 protein expression and tumor response, and to validate potential predictive biomarker(s) in an independent cohort. BACKGROUND: Neoadjuvant chemoradiotherapy (nCRT) followed by surgery has become a standard of care for esophageal adenocarcinoma (EAC). However, the response to nCRT is highly variable among patients. METHODS: EAC patients who underwent nCRT and surgery, between January 2003 and December 2014 at the Erasmus University Medical Center, were included and divided into a primary (n = 77) and a validation cohort (n = 70)...

BACKGROUND: Accurate T-staging is pivotal for predicting prognosis and selecting appropriate therapies for esophageal squamous cell carcinoma (ESCC). The diagnostic performance of fluorodeoxyglucose (FDG) positron emission tomography/computed tomography (PET/CT) for its T-staging is uncertain. We investigated use of FDG PET/CT for preoperative T-staging of patients with ESCC. METHODS: Patients with ESCC given preoperative FDG PET/CT scans, either with (CRT([+]) group) or without (CRT([-]) group) neoadjuvant chemoradiotherapy, were retrospectively reviewed...

Pregnancy-associated gastric cancer is extremely rare. In many cases, it is diagnosed at an advanced stage because the symptoms during pregnancy are generally overlooked. We report three cases of gastric cancer during pregnancy with various outcomes. The first case included a patient with stage IV gastric cancer who received palliative chemotherapy. This patient had a preterm birth and died 7 months after diagnosis. The second case received neoadjuvant chemotherapy during pregnancy and a total gastrectomy was performed after delivery...
