Filter by:The project investigates the feasibility of laparoscopic fluorescent imaging for the intraoperative detection of the sentinel lymph node (SLN) in colon cancer patients. In addition, the topology of immunological and microenvironmental changes in normal and invaded lymph nodes (LN's) will be correlated to the LN location (anatomical mapping).
Due to the great toxicity of chemotherapeutic drugs to both the healthy and cancerous area, the efficient targeting could be of great benefit for a patient with advanced or metastatic tumors. Colorectal cells carry somatostatin receptors which make them a promising target for antitumor therapy since this would reduce side effects and increase drug delivery efficacy to the target site.
Primary objective - Evaluate the efficacy in terms of progression-free survival (PFS) of aflibercept in combination with FOLFIRI in patients treated routinely for metastatic colorectal cancer (mCRC) after failure of treatment with oxaliplatin + EGFR. Secondary objective - Evaluate the efficacy of aflibercept in combination with FOLFIRI on the 2-year overall survival rate and the objective response rate. - Evaluate the tolerance profile of aflibercept in combination with FOLFIRI. - Observational study, national, multicenter, cohort, prospective without intervention on the therapeutic strategy.•
This project has for objective to demonstrate that the increase of the distance "Patient home - center of treatment" may be associated with significant, other noticeable, noted events. This distance may also be available in the Rouen University Hospital. The study of the association in this distance and the delay in initiating chemotherapy after surgery in patients treated at the CHU correspond to a pilot study prior to the completion of the analysis at the regional scale.
This study is designed to:(1) determine the efficacy of Traditional Chinese Medicine (TCM) 'Tonifying Spleen and Kidney Sequential Regimen' (TSKSR) in improving the completion rate of 8-cycle CapeOX chemotherapy in patients with stage II (high-risk)& III colon cancer;(2) evaluate the efficacy of the TCM-TSKSR on adverse events of CapeOX chemotherapy and it's impact on patients' quality of life (QoL).A randomized,double-blinded,placebo-controlled clinical trial including seven centers will be conducted in Mainland China.The study will enroll patients with stage II (high-risk)& III colon cancer who have completed radical surgery and are going to receive CapeOX chemotherapy.All participants will receive chemotherapy as prescribed by their treating physicians and be randomly assigned to either concurrent use of TCM-TSKSR or placebo.
The study is designed to elucidate whether carbon black suspension endoscopic tattoo enhances visibility of lymph nodes or tumor tissue on dissection of colonic surgical specimen, thereby making improvement in staging defined as better pTNM stage via better visualisation of carbon marked metastatic or sentinel lymph nodes or marked primary tumor or adjacent tissues.
Basing on the strong evidence from former researches, patients with CRLM can benefit from the treatment of bevacizumab combined with sencond-line chemotherapy. Recently, although with the popularization of RFA, the role that RFA plays in the long term survival of patients with metastatic colorectal cancer (CRC) is still confused. In this designed, randomized, controlled, prospective, and open clinical trial, the effectiveness of RFA combined with second-line chemotherapy + bevacizumab on unresectable CRLM is going to be evaluated compared with that of second-line chemotherapy + bevacizumab. After screened by inclusion and exclusion criteria, the eligible subjects will be randomly allocated into the experimental group-with the treatment of RFA + second-line chemotherapy + bevacizumab and control group-with the treatment of second-line chemotherapy + bevacizumab equally.
RATIONALE: Recently, the importance of prognosis according to the location of the primary tumor in colorectal cancer has been raised. In the CALGB / SWOG 80405 study published in 2016, the addition of bevacizumab or cetuximab to the first line FOLFIRI / FOLFOX in KRAS (codon 12, 13) wild type metastatic colorectal cancer (mCRC) patients did not show a significant difference between overall survival (OS) and progression free survival (PFS) in both groups. Alan P. Venook et al. published a follow-up subgroup analysis on the effect of primary tumor location at 2016 ASCO. In the treatment group with cetuximab, the difference in treatment effect was significant according to the primary tumor location. The right colon cancer showed a poor prognosis for cetuximab treatment. (PFS: 7.8 vs 12.4 months, HR 1.56, p <0.0001 / OS: 16.7 vs 36.0months, HR 1.87, P <0.0001). Therefore, the investigators propose a phase II trial for the efficacy evaluation of bevacizumab-FOLFOXIRI and bevacizumab-FOLFIRI or FOLFOX treatment in patients with poor prognosis of unresectable right-sided colorectal cancer.
To evaluate the efficacy and safety of neoadjuvant FOLFOXIRI chemotherapy (irinotecan, oxaliplatin and fluorouracil) in the patients with locally advanced colon cancer.
Vecchione et al showed that suppression of RANBP2 results in mitotic defects only in BRAF-like colon cancer (CC) cells, which leads to cell death. Mechanistically, RANBP2 silencing reduces microtubule outgrowth from the kinetochores, thereby inducing spindle perturbations, providing an explanation for the observed mitotic defects. Vinorelbine mimics RANPB2 silencing in BRAF-like and BRAFV600E CC cell lines. These preclinical data represent a strong rationale to also explore the anti-tumor activity of vinorelbine in patients with advanced BRAF-like (both BRAFm and BRAF wild type) CC. Tumors having this gene signature are referred to as "BRAF-like" and have a similar poor prognosis irrespective of the presence of BRAF(V600E) mutation. Since vinorelbine is standard of care in advanced breast and NSCLC, there is ample experience with the dose and schedule as well as with the safety profile and supportive measures required to prevent side-effects.
