Filter by:Cancer patients undergo many different modalities of treatments. Pharmacological treatment should be well understood. The nutritional status is not taken into account when calculating drug's doses and this may have an impact in toxicity and quality of life. The present study proposes to evaluate the relationship between the calculation of pharmacological treatment's doses, the toxicity and the impact on quality of life among colorectal and breast cancer's patients.
A open label 1:1 randomized phase II exploratory study investigating adjuvant therapy in patients with molecular biologically detectable residual disease after primary resection for localized colorectal tumors.
Adjuvant chemotherapy was unnecessary in pathological stage Ⅱ colorectal cancer following initial treatment of surgery without high risk factors of recurrences. The treatment efficacy of adjuvant chemotherapy for pT1-3N0M0 colorectal cancer following preoperational chemotherapy or chemoradiotherapy remains unclear. Part of clinical local advanced colorectal cancer(cTxN1-2M0), which turn out to be pT0-3N0M0 after preoperational chemotherapy or chemoradiotherapy, might not really need adjuvant chemotherapy due to the down-stage efficacy of the preoperational treatments, or the misleading by lymph nodes false-positive imaging diagnosis.
Studies have shown that tumors from the same patient may respond very differently to the same therapeutic agents. This study aims to investigate the genetic basis of tumors that respond abnormally well or poorly to therapeutic agents in an effort to understand the fundamental genetic basis of this response. The present protocol seeks to retrospectively perform Exome, next-generation (DNA) sequencing and/or other molecular techniques on tumor samples to identify the genetic basis of a patient's exceptional response to chemotherapy.
This study is a first in human Phase 1 study that involves patients with a type of cancer called HER2 (Human Epidermal Growth Factor Receptor 2) positive cancer. This study asks patients to volunteer to take part in a research study investigating the safety and efficacy of using special immune cells called HER2 chimeric antigen receptor specific cytotoxic T lymphocytes (HER2 specific CAR T cells), in combination with intra-tumor injection of CAdVEC, an oncolytic adenovirus that is designed to help the immune system including HER2 specific CAR T cell react to the tumor. The study is looking at combining these two treatments together, because we think that the combination of treatments will work better than each treatment alone. We also hope to learn the best dose level of the treatments and whether or not it is safe to use them together. In this study, CAdVEC will be injected into participants tumor at one tumor site which is most easiest to reach. Once it infects the cancer cells, activation of the immune response will occur so it can attack and kill cancer cells. (This approach may have limited effects on the other tumor sites that have not received the oncolytic virus injection, so, patients will also receive specific T cells following the intratumor CAdVEC injection.) These T cells are special infection-fighting blood cells that can kill cells infected with viruses and tumor cells. Investigators want to see if these cells can survive in the blood and affect the tumor. Both CAdVEC and HER2-specific autologous CAR T are investigational products. They are not approved by the FDA.
This is a prospective, multicenter, observational, single-blinded controlled study. Dynamic monitoring of patients with resectable colorectal cancer was performed using the previously established colorectal tumor-specific plasma ctDNA methylation markers (Multigene methylation detection). Dynamic monitoring of plasma ctDNA methylation before and after treatment and at regular follow-up in patients with colorectal cancer after radical resection of tumor, to explore the predictive effect of postoperative plasma ctDNA methylation on postoperative recurrence and whether dynamic monitoring of postoperative ctDNA methylation could be earlier than imaging examination to indicate tumor recurrence.
The purpose of this study is to evaluate the safety, tolerability and pharmacokinetics, and determine the maximum tolerated dose of ZSP1241 in participants with hepatocellular carcinoma, cholangiocarcinoma, gastric cancer, esophageal cancer, colorectal cancer and other advanced solid tumors.
This clinical trial aims to evaluate the efficacy, safety of FOLFIRI with vemurafenib and cetuximab in Advanced Colorectal Cancer Patients with BRAF V600E mutation.
The study aims to compare the effects of chemoradiation versus radical surgery in treating retro-peritoneal or para-aortic lymph node metastasis in colorectal cancer. By prolonging patients' progression-free survival, local control rate and overall survival, investigators can conclude the best regimen for colorectal cancer patients.
This single-arm study will evaluate the resection rate of liver metastases in patients with metastatic colorectal cancer and borderline unresectable liver metastases receiving treatment with bevacizumab in combination with modified-FOLFOXIRI as first line treatment. Patients will receive bevacizumab (5 mg/kg) plus modified-FOLFOXIRI (irinotecan 150 mg/m2, oxaliplatin 85 mg/m2, leucovorin 200 mg/m2, and fluorouracil 2400 mg/m2 as a 46-h continuous infusion) every 14 days as neoadjuvant chemotherapy regimen. This study treatment will continue until surgery, disease progression, unacceptable toxicity, or patient refusal.
