Rationale: Adjuvant chemotherapy after surgery significantly improved the survival of PC patients, but there is a problem that only about 50% of patients start adjuvant chemotherapy after pancreatectomy. Neoadjuvant chemotherapy might control potential metastatic lesion which are not being detected in early diseases status and improve the R0 resection rate. In addition, it prevents futile surgery by selecting patients with rapid progression of disease. Furthermore, compared to chemotherapy administered after surgery, more patients can complete the planned chemotherapy schedule in neoadjuvant setting. Asians differ from Westerners not only in racial differences, but also in average size and body surface area. Accordingly, there is an urgent need for clinical studies on the dose, toxicity, dosing cycle, and efficacy of anticancer drugs that reflect actual clinical trials in Asian countries for Asians. There are still few studies worldwide that prospectively explored the efficacy of neoadjuvant chemotherapy in resectable PC and the administration of neoadjuvant therapy in resectable PC depends on individual clinical judgment. Therefore, systematic and prospective clinical trials are essential to standardize treatment protocol in resectable PC. Obective: To investigate whether 6 cycles of preoperative mFOLFIRINOX - surgery - 6 cycles of postoperative mFOLFIRINOX improves overall survival by intention-to-treat compared to surgery followed by 12 cycles of postoperative mFOLFIRINOX. Study design: open-label, multicenter, randomized, phase 3 clinical trial Study population: Patients with resectable pancreatic cancer and ECOG performance 0 or 1. Intervention: Invervention arm : 6 cycles of neoadjuvant mFOLFIRINOX followed by surgical resection and 6 cycles of adjuvant mFOLFIRINOX Comparator arm : surgical resection followed by 12 cycles of adjuvant mFOLFIRINOX Primary endpoint: 2-year overall survival rate by intention-to-treat
This is a prospective and observational clinical study for seeking out a better way to predict the pathologic complete response (pCR) in patients with advanced gastric cancer (AGC) based on the post-neoadjuvant treatment Magnetic Resonance Imaging (MRI) and CT data. This study will help the surgeons to better formulate treatment regimens for gastric cancer in the clinical practice.
DRAGON III research, Neoadjuvant Chemotherapy (FLOT versus SOX) for Gastric Cancer, is an investigator initiated; phase 3, open label, multi-center randomized controlled study.
Neoadjuvant chemotherapy is an important treatment for breast cancer patients. Patients with triple negative or Her2 enriched subtype who achieved pCR after neoadjuvant chemotherapy would have longer survival. But the overall pCR rate of breast cancer was about 20%. So, different methods have tried to improve pCR rate.Drug sensitivity screening in vitro for different chemotherapy drugs was a promising method for improving pCR rate. But there was no method could select effective drugs accurately for breast cancer patients until now. This study will explore whether drug screening by culturing breast cancer cells in vitro from breast cancer tissue could improve pCR rate compared with traditional neoadjuvant chemotherapy. Breast cancer patients who were candidates for neoadjuvant chemotherapy will be allocated two group. One group will receive neoadjuvant cheotherapy according physician's choices. Another group will receive neoadjuvant chemotherapy according results of drug sensitivity results by in vitro cell culture. pCR rate will be compared between two groups to explore whether drug sensitivity screening could improve pCR rate.
Breast cancer is the most common malignant tumor in women worldwide,and there exist a large part of patients need to receive neoadjuvant chemotherapy(NAC) before the curative surgery.Circulating tumor DNA(ctDNA) is the circulating free DNA in the blood that originates from cancers,and it can be detected by modern technologies in plasma.In this prospective study,investigators aim to observe the correlation between tumor response to neoadjuvant chemotherapy and ctDNA.
Neoadjuvant chemotherapy (NAC) has become the standard therapy for both locally advanced and early-stage breast cancer in recent years for the improvement breast conserving surgery rate and the evaluation of treatment response in vivo. Pathological complete response (pCR) is an independent prognostic factor irrespective of breast cancer intrinsic subtypes after NAC. The trial is designed to compare effectiveness between anthracycline and/or taxane as neoadjuvant chemotherapy for operable advanced breast cancer in different molecular typing. In this trial the investigators will randomly assign 200 primary breast cancer patients to receive six cycles of fluorourcil, epirubicin,and cyclophosphamide(FEC), or four cycles of epirubicin and cyclophosphamide (EC) followed by four cycles of docetaxel(T), or six cycles of docetaxel and cyclophosphamide (TC). Trasuzumab was recommended combining docetaxel to patients if HER-2 positive.The effectiveness of therapy will be estimated after every two cycles of neoadjuvant chemotherapy. Surgery will be performed after completing designated full cycles of neoadjuvant chemotherapy. The primary endpoint is to assess pathologic complete response (pCR, ypT0/is ypN0) rate in different regiments. The secondary endpoint is to assess the relationship between pCR rate with molecular typing in different regiments, so that the investigators could optimize neoadjuvant chemotherapy regiment according to molecular typing.
