Filter by:Although the incidence of gastric cancer has been substantially declining for several decades, it is still the sixth most common cancer and the fourth most frequent cause of cancer death worldwide. Surgery is still the only curative option for gastric cancer. However, most patients are unable to undergo surgery because of late stage, unresectable disease. The prognosis for these patients is very poor. Although the Magic trial showed that perioperative chemotherapy can increase the rate of curative surgery and significantly improve overall survival in patients with operable gastric or lower esophageal adenocarcinomas, no pCR events were reported in this trial. The intervention arm in PREACT consists of pre-operative chemotherapy, pre-operative radiochemotherapy, surgery and post-operative chemotherapy. The control arm consists of pre-operative chemotherapy, surgery, and post-operative chemotherapy. The primary purpose of PREACT is to investigate whether the addition of radiochemotherapy to chemotherapy is superior to chemotherapy alone in the pre-operative setting in improving disease free survival in patients with locally advanced gastric or esophagogastric junction adenocarcinoma.
Rectal cancer, comprised of 30% of overall colorectal cancer cohort, is one of the leading cancers of Taiwan. In patients with advanced disease, the standard of care is concurrent chemoradiotherapy (CCRT) before surgery. After CCRT, the abscopal effect, a phenomenon that localized radiation not only destroys local tumor but also inhibits the growth of tumor at the remote site, has been observed. This effect is believed to be associated with tumor immune response. In addition, other immune checkpoint molecules, such as Programmed cell death-1(PD-1), Programmed cell death ligand-1 (PD-L1), and Cytotoxic T-Lymphocyte Associated Protein 4 (CTLA-4), have been reported associated with therapeutic outcome. However, after CCRT, more than 50% of patients were still either having persistent disease or developed distant metastasis. To improve therapeutic outcome of patients with rectal cancer, this project, thus, aims at exploring the evolution of factors that may affect the abscopal effect and immune checkpoint functions in tissues and in blood before and after CCRT.
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
In this phase II study, the investigators aim to evaluated the efficacy and toxicity of definitive concurrent chemoradiotherapy (CCRT) with docetaxel plus cisplatin (DP regimen) versus 5-fluorouracil plus cisplatin (PF regimen) in patients with esophageal squamous cell carcinoma (ESCC).
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.
The investigators designed a new preoperative chemoradiotherapy regimen to focus on the most important radiation area and hope to reduce the radiation volume and try to reduce the postoperative mortality and treatment-related mortality.
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.
This is a prospective case control study. Participants will be enrolled as case subjects or control subjects, depending upon the gonadotoxicity of their chemoradiation therapy. The chemotherapeutic regimens will be determined per standard of care. Participants will receive GnRHa (Lupron) as standard of care for menstrual suppression. Blood draws and pelvic ultrasound at baseline, 6 months and 12 months post completion of chemotherapy are the interventions. The duration of the study will be approximately 12 months.The study time includes the time necessary for completion of most cancer treatments in this population, which approximates 8-12 months, and time to allow complete excretion of the Lupron from the systemic circulation with reliable testing of the hypothalamic pituitary ovarian (H-P-O) axis. The results of the study will be used to guide a larger study evaluating the efficacy of gonadotropin releasing hormone agonist (GnRHa) as ovarian preservation therapy in young subjects receiving chemoradiation.
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.
Locally advanced nasopharyngeal carcinoma patients(UICC7th stageIII to IVb) will receive either cisplatin plus 5-fluorouracil (PF) or docetaxel plus cisplatin and 5-fluorouracil(TPF) neoadjuvant chemotherapy with concurrent chemoradiation.
