Filter by:Though refusal of radical surgery was often happened in rectal cancer patient after neoadjuvant chemoradiotherapy, little is currently known about the actual oncologic outcome of it. Thus the investigators designed this study to compare the oncologic outcome of unintended rectal preservation with intended rectal preservation by surgeon.
The ENSURE study will comprise two phases. Phase 1: European multicenter survey of surveillance protocols after esophageal cancer surgery ENSURE questionnaire will be circulated to representatives from participating European countries. Phase 2: European multicenter retrospective observational study of the impact of postoperative surveillance protocols on oncologic outcome and HR-QL Phase 2 will constitute a retrospective observational study of patients undergoing treatment with curative intent for esophageal cancer at participating Centers from June 2009 to June 2015.
The aim of this observational study is to retrospectively collect survival data for 3000 primary esophageal cancer patients from multicenter between January 2000 to present. Based on a Cox model, we want to develope a nomogram that predicts local recurrence, distant metastases, and survival for patients treated with radiotherapy or chemoradiotherapy with or without chemotherapy.
Pancreaticoduodenectomy is associated with high perioperative morbidity, with surgical site infection (SSIs) being one of the most common complications. A retrospective study at Hopkins on SSIs in these patients identified the rate of SSIs to be 16.7% and pre-operative bile stent/drain and neoadjuvant chemotherapy were independent predictors of surgical site infection. Patients with these factors having a predicted risk of up to 32%. Another subsequent retrospective study demonstrated that the use of negative pressure wound therapy device was significantly associated with a decrease in the rate of SSIs. The hypothesis of the investigator(s) for the current study is that placement of Prevena Peel & Place Dressing (Negative Pressure Wound Therapy, NPWT) in patients undergoing pancreaticoduodenectomy who are at high risk of SSIs will result in a significant decrease in their SSI rate.
Ratiotherapy alone is the current standard treatment for elderly esophageal or esophagogastric cancer in China. And Little is known about chemoradiotherapy (CRT) in elderly patients. This study aimed to assess the efficiency and safety of simultaneous integrated boost (SIB) intensity modulated radiation therapy (IMRT) with S1 based SIB-IMRT followed by adjuvant chemotherapy with S1 in in elderly (age ≥70 years) esophageal or esophagogastric cancer patients
The objective of this multicenter retrospective study is to compare overall survival in patients with stage IIIA-N2 NSCLC treated with neoadjuvant treatment and surgery versus definitive chemoradiation. Secondary objectives are to analyze disease-free survival, median survival, locoregional and distant relapses as well as mortality and toxicity related to treatment.
This was a randomised, multicenter, phase 3 trial. Patients who were age of 70 years or older with histologically confirmed esophageal cancer were randomly assigned to S-1 concurrent with radiotherapy or radiotherapy alone.The primary endpoint was overall survival.
To quantify motion based variation of the target volume of the primary tumor over the course of chemoradiotherapy in esophageal cancer patients, and to use this information to calculate appropriate PTV (planning target volume) margins according to the margins recipe for patients receiving trimodality (neoadjuvant chemoradiation and surgery) or definitive chemoradiation in order to personalize radiation treatment, resulting in either better target coverage or a reduction in normal tissue radiation exposure.
Because locally far-advanced gastric cancer combined with adjacent tissue invasion has a poor prognosis, some phase 2 and 3 clinical trials of neoadjuvant chemotherapy (NAC) are performed in Japan. However, neoadjuvant chemoradiotherapy (NACRT) achieves superior local tumor control compared with NAC. This feasibility trial explored the feasibility and safety of neoadjuvant chemoradiotherapy (NACRT) in this type of gastric cancer.
