Background/objectives: Tumor microenvironmental hypoxia is an established hallmark of solid tumors. It significantly contributes to tumor aggressiveness and therapy resistance and has been reported to affect the balance of activating/inhibitory surface receptors' expression and activity on NK cells. In the current study, we investigated the impact of hypoxia on the surface expression of Siglec-7 and Siglec-9 (Sig-7/9) and their ligands in NK cells and tumor target cells.

We evaluated the safety profile of LS-HIPEC for patients with positive peritoneal cytology (PPC) or carcinomatosis from GA.
Methods: Outcomes were reviewed of patients with stage IV GA with peritoneal involvement who received LS-HIPEC from June 2014 to January 2017.
Objective: During neoadjuvant chemoradiotherapy for oesophageal cancer, or in the interval prior to surgery, some patients develop systemic metastasis. This study aimed to evaluate the diagnostic performance of F-FDG PET/CT for the detection of interval metastasis and to identify predictors of interval metastases in a large cohort of oesophageal cancer patients.
Methods: In total, 783 consecutive patients with potentially resectable oesophageal cancer who underwent chemoradiotherapy and pre- and post-treatment F-FDG PET/CT between 2006 and 2015 were analyzed from a prospectively maintained database.
Purpose: To develop a nomogram that estimates 1-year recurrence-free survival (RFS) after trimodality therapy for esophageal adenocarcinoma and to assess the overall survival (OS) benefit of esophagectomy after chemoradiotherapy (CRT) on the basis of 1-year recurrence risk.
Methods: In total, 568 consecutive patients with potentially resectable esophageal adenocarcinoma who underwent CRT were included for analysis, including 373 patients who underwent esophagectomy after CRT (trimodality therapy), and 195 who did not undergo surgery (bimodality therapy). A nomogram for 1-year RFS was created using a Cox regression model.
Objective: To determine the impact of histology on pathologic response, survival outcomes, and recurrence patterns in patients with esophageal cancer (EC) who received neoadjuvant chemoradiotherapy (CRT).
Summary Of Background Data: There is a paucity of data regarding comparative outcomes after neoadjuvant CRT between esophageal squamous cell carcinoma (SCC) and adenocarcinoma.
Methods: Between 2002 and 2015, 895 EC patients who underwent neoadjuvant CRT followed by esophagectomy at 3 academic institutions were retrospectively reviewed, including 207 patients with SCC (23.
Purpose: In patients with esophageal cancer (EC), intensity modulated radiation therapy (IMRT) improves dose sparing to the heart and lung, with some evidence showing clinical benefit. Herein, we report our cumulative clinical experience with the use of IMRT for EC.
Methods And Materials: This is a retrospective analysis of 587 patients with nonmetastatic EC who were treated consecutively with IMRT from January 2004 to June 30, 2013.
Purpose: To assess the contribution of induction chemotherapy (IC) before definitive chemoradiation therapy (dCRT) in patients with esophageal cancer (EC) based on recursive partitioning analysis (RPA).
Methods And Materials: A total of 496 eligible patients with EC staged by positron emission tomography (PET) who received dCRT from 1998 to 2015 were included, 162 (32.7%) of whom underwent IC before dCRT.
Purpose: The aim of this phase II study was to perform neoadjuvant hyperthermic intraperitoneal chemoperfusion (HIPEC) via a minimally invasive approach without cytoreduction for patients with gastric cancer and positive peritoneal cytology or low-volume peritoneal carcinomatosis.
Methods: Patients with gastric or gastroesophageal adenocarcinoma and positive peritoneal cytology or radiologically occult peritoneal carcinomatosis after systemic chemotherapy received laparoscopic HIPEC with mitomycin C 30 mg and cisplatin 200 mg. Patients whose peritoneal disease resolved were offered gastrectomy.
Objective: To discern recurrence risk stratification and investigate its influence on postoperative surveillance in patients with esophageal adenocarcinoma (EAC) after neoadjuvant chemoradiotherapy (CRT).
Background: Reports documenting recurrence risk stratification in EAC after neoadjuvant CRT are scarce.
Methods: Between 1998 and 2014, 601 patients with EAC who underwent neoadjuvant CRT followed by esophagectomy were included for analysis.
This study aimed to determine whether F-FDG PET response after induction chemotherapy before concurrent chemoradiotherapy can identify patients with esophageal adenocarcinoma who may benefit from subsequent esophagectomy. We identified and analyzed 220 patients with esophageal adenocarcinoma who had received induction chemotherapy before chemoradiotherapy, with or without surgery, with curative intent; all underwent F-FDG PET scanning before and after induction chemotherapy. F-FDG PET responders were defined as patients who achieved complete response (CR) after induction chemotherapy (maximum SUV ≤ 3.

Methods: Between 1998 and 2015, 535 patients with esophageal cancer who underwent nCRT were included for analysis, including 218 patients who received IC before nCRT (IC group) and 317 patients who did not receive IC (non-IC group). A prognostic scoring model was developed to predict disease-free survival (DFS) on the basis of a Cox proportional hazards model.
Purpose: The purpose of our study was to determine the value of F-FDG PET before and after induction chemotherapy in patients with oesophageal adenocarcinoma for the early prediction of a poor pathologic response to subsequent preoperative chemoradiotherapy (CRT).
Methods: In 70 consecutive patients receiving a three-step treatment strategy of induction chemotherapy and preoperative chemoradiotherapy for oesophageal adenocarcinoma, F-FDG PET scans were performed before and after induction chemotherapy (before preoperative CRT). SUV, SUV, metabolic tumour volume (MTV), and total lesion glycolysis (TLG) were determined at these two time points.
Background: A randomized phase III study established docetaxel, cisplatin, and 5-fluorouracil (DCF) as one of the standard treatments for patients with untreated advanced gastric cancer (AGC). However, DCF use is limited due toxicity. With the purpose to evaluate a less toxic regimen, we conducted a single arm, phase I/II trial of modified DCF (oxaliplatin, 5-fluorouracil, and docetaxel [D-FOX]) for untreated AGC patients.
View Article and Find Full Text PDFBackground: It is currently unclear whether the superior normal organ-sparing effect of intensity-modulated radiotherapy (IMRT) compared with 3-dimensional radiotherapy (3D) has a clinical impact on survival and cardiopulmonary mortality in patients with esophageal cancer (EC).
Methods: The authors identified 2553 patients aged > 65 years from the Surveillance, Epidemiology, and End Results (SEER)-Medicare and Texas Cancer Registry-Medicare databases who had nonmetastatic EC diagnosed between 2002 and 2009 and were treated with either 3D (2240 patients) or IMRT (313 patients) within 6 months of diagnosis. The outcomes of the 2 cohorts were compared using inverse probability of treatment weighting adjustment.
Background: This study aimed to determine whether postoperative morbidity and mortality rates increased after preoperative chemoradiation in patients who underwent gastrectomy.
Methods: The medical records of 7404 patients with gastric or gastroesophageal cancer seen from January 1995 to August 2012 were reviewed to identify patients who underwent gastrectomy. χ (2) and logistic regression analysis were used to determine differences in the 90-day postoperative morbidity and mortality rates of patients who underwent upfront surgery (SURG), preoperative chemotherapy (CHEMO), or preoperative chemoradiation (CHEMOXRT).
Background: Chronic comorbidities and some of the commonly-used medications are thought to affect cancer patients' outcomes, but their relative impact on esophageal carcinoma (EC) has not been well studied. The purpose of the study was to identify the chronic comorbidities and/or commonly-used medications that impact EC patient survival.
Methods: A total of 1174 EC patients treated with chemoradiotherapy (CRT) with or without surgery in one institution from 1998 to 2012 were retrospectively included.
Objectives: We reviewed survival outcomes and factors associated with improved outcomes for patients with stage IVB esophageal cancer who received multimodality therapy with initial chemotherapy followed by concurrent chemoradiation (CRT)±surgery.
Methods: We retrospectively identified 96 patients with stage IVB esophageal carcinoma (with positive nonregional lymph nodes and/or distant organ metastasis) treated at a single institution with chemotherapy followed by concurrent CRT, with or without surgery. The Cox proportional hazard model was used to test associations between overall survival (OS), disease-free survival (DFS), locoregional relapse, distant metastasis-free survival, and potential predictive factors.
Background: Docetaxel, cisplatin, and 5-flurouracil (DCF) administered every 3 weeks produces a high rate of treatment-related adverse events. The objective of the current study was to evaluate the efficacy and tolerability of a weekly formulation of DCF.
Methods: Data from 117 patients treated at The University of Texas M.
Purpose: We conducted a phase II trial to assess the outcomes of patients who received preoperative gemcitabine-based chemoradiation and pancreaticoduodenectomy (PD) for stage I/II pancreatic adenocarcinoma.
Patients And Methods: Eligible patients with pancreatic head/uncinate process adenocarcinoma and radiographically defined potentially resectable disease received chemoradiation with 7 weekly intravenous (IV) infusions of gemcitabine (400 mg/m(2) IV over 30 minutes) plus radiation therapy (30 Gy in 10 fractions over 2 weeks). Patients underwent restaging 4 to 6 weeks after completion of chemoradiation and, in the absence of disease progression, were taken to surgery.
Purpose: We conducted a phase II trial of preoperative gemcitabine and cisplatin chemotherapy in addition to chemoradiation (Gem-Cis-XRT) and pancreaticoduodenectomy (PD) for patients with stage I/II pancreatic adenocarcinoma.
Patients And Methods: Chemotherapy consisted of gemcitabine (750 mg/m(2)) and cisplatin (30 mg/m(2)) given every 2 weeks for four doses. Chemoradiation consisted of four weekly infusions of gemcitabine (400 mg/m(2)) combined with radiation therapy (30 Gy in 10 fractions administered over 2 weeks) delivered 5 days per week.
Objectives: The size of pancreatic tumors that can be diagnosed by preoperative imaging continues to decrease because advances in diagnostic imaging. Several surgical series have suggested that survival is better in tumors 20 mm or smaller (vs tumors >20 mm), but the incremental benefit of diagnosing progressively smaller tumors from 30 mm (currently, the average size of pancreatic tumor at diagnosis) to 20 mm or smaller is not known. We investigated survival and resectability as tumor size increased from 20 mm or smaller to 30 mm or larger.

Pancreatic cancer is a lethal disease characterized by multiple disease-related symptoms. Chemoradiation therapy is a standard of treatment for locally advanced pancreatic cancer. Although shown to prolong survival, there is little information about treatment-related symptoms or the palliative benefits of chemoradiation.
