Filter by:The main reason of cancer-related mortality is the spread of cancer cells to distant sites (micrometastases). However, only a few small groups of tumor cells can metastasize by acquiring mechanism to decrease the immune response. Changes in the systemic inflammatory response to the tumor can be measured by blood-based parameters. In particular, the proportion of neutrophyls- lymphocytes (NL) has been evaluated for predicting the survival of patients with different types of cancer. The first strategy to treat colorectal cancer (CCR) is complete resection of the lesion. Nevertheless, some patients experience recurrence, probably due to residual micrometastases. We have demonstrated that analysis of some resistance proteins (Tyms / MRP1) in circulating tumor cells (CTCs) may predict treatment response in metastatic CCR patients (mCRC). We also note that the CTCs kinetics can show response to therapy. Patients with stage III disease in the colon / rectum, although showing high cure rate, generally fall locally or remotely and studies with blood markers in this group of patients is still scarce. Primary Objective: To investigate cells found in the blood (lymphocytes and neutrophils and CTCs) to verify if they can help in the choice of anti-neoplastic therapy in patients with advanced colon and rectum cancers. Secondary objectives: - to evaluate the influence of CTC kinetics in response to treatment of patients with advanced colon/rectum cancers; - to check the expression of treatment resistance, invasion and proliferation proteins (Tyms, TGF-βR, MMP-2, β-gal, Ki-67 and CD45) in CTCs and their correlation with response to treatment; - to check the mRNA expression of the same genes observed by immunocytochemistry in CTCs and their correlation with response to treatment; - to quantify CTCs, neutrophils and lymphocytes of patients included in this study and verify if there are correlation among their rates and progression-free survival. Methods: there will be collected 10 ml of blood of patients with advanced colon and rectal cancer for analysis of CTCs, lymphocytes / neutrophils. CTCs will be isolated, quantified and analyzed after separation by ISET method (Rarecells/France). The marker analysis of these cells will be done by immunocytochemistry and the gene expression will be assessed by RNAscope. The quantification of lymphocytes/neutrophils will be made by common blood count in Delboni laboratory. Expected Results: We propose to show that not only the count and the kinetics of CTCs, but also their molecular characteristics, can provide relevant information to clinicians. Hopefully, by quantification of neutrophils and lymphocytes, we will be able to identify new prognostic blood biomarkers that can direct clinicians to the best therapeutic choice.
The present phase I trial evaluates the feasibility of a postoperative stereotactic hypofractionated external beam radiation therapy delivered in patients who underwent radical prostatectomy with adverse pathological features or early biochemical failure. Modern computer-driven technology enables the implementation of ultra-high hypofractionated Image-Guided Radiotherapy (IGRT) safely. Eligible patients for this study are those with: - Adenocarcinoma of the prostate treated with radical prostatectomy (any type of radical prostatectomy is permitted including retropubic, perineal, laparoscopic or robotically assisted; there is no time limit for the date of radical prostatectomy) - Pathologic (p)T3 disease, positive margin(s), Gleason score 8-10, or seminal vesicle involvement - Undetectable post-radical prostatectomy PSA that becomes detectable and then increases on 2 subsequent measurements (PSA of > 0.1 - ≤ 2.0 ng/mL) - Life expectancy: 10 years - ECOG performance status of 0 -1 - No distant metastases, based on the following workup within 60 days prior to registration - Magnetic resonance imaging (MRI) of the pelvis - PSMA/Choline Positron Emission Tomography (PET) to exclude systemic disease in patients with biochemical recurrence - Patients can be on androgen deprivation therapy - Ability to understand and willingness to sign a study-specific informed consent prior to study. Patients enrolled in the study will undergo image-guided, volumetric intensity-modulated arc radiotherapy (IGRT-VMAT) with state-of-the-art treatment-planning and quality assurance procedures with emphasis on normal tissue sparing and delivery accuracy via the use of devices that ensure stability and beam location reproducibility.
In radiotherapy high-tech scans with x-rays (CT scans) are taken before and during treatment to locate the tumour and ensure the radiation is hitting the target. These x-rays expose patients to additional radiation and the quality of these scans is often poor which makes it difficult to distinguish tumour from normal tissue and there may be uncertainty in the tumour position due to movement or shrinkage. To allow for these uncertainties a large margin around the tumour is also treated, but this means that large volumes of normal tissue also receive significant doses of radiation, which can result in early and late toxicity. MRI (magnetic resonance imaging) is better than CT scanning at being able to tell the difference between tumour and normal tissues and does not expose patients to additional radiation. A new machine called an MR Linac (or magnetic resonance imaging-guided linear accelerator) integrates high quality MRI with a state-of-the-art radiotherapy machine and the Institute of Cancer Research (ICR)/The Royal Marsden Hospital (RMH) are currently installation a prototype, which will be one of the first in the world. This revolutionary technology has the potential to change the way radiotherapy is delivered. We hope the improved precision and accuracy in hitting the target will mean reductions in margins around tumours and that this will lead to higher cure rates with significantly fewer side effects. Studies are required to simulate treatment on the MR Linac before it can be used in routine clinical practice and to conduct these studies, we need to obtain MRI scans on volunteers and patients who are currently undergoing treatment. This study will involve imaging with MRI in healthy volunteers as well as in patient volunteers before and during their standard course of radiotherapy to allow us to develop MRI sequences derived on the MR Linac for MR Linac-based research focusing on clinical application and establishment into a MR-CT and MR only workflow, treatment adaptation and quality assurance.
The purpose of this feasibility study is to determine whether a structured exercise programme prior to oesophagectomy has: acceptable adherence, is safe, and improves physiological measures of physical fitness above standard care.
The purpose of this study is to test the safety of adding a new drug, durvalumab (also called MEDI4736), to chemoradiation with either FOLFOX/Capeox or carboplatin and paclitaxel, following initial chemotherapy with FOLFOX. The investigators want to find out what effects, good and/or bad, this combination has on the patient and cancer.
In patients with resectable pancreatic duct adenocarcinoma (PDAC), curative surgery followed by adjuvant chemotherapy is currently the standard of care. However, the long-term results are still poor, with median disease-free and overall survival of 14 months and 23 months. The corresponding 5-year overall survival rate is 20%. Chemotherapy before surgery (neoadjuvant chemotherapy) allows identification of patients with rapidly progressive metastatic disease at time of preoperative restaging (surgery is then avoided in these patients), and may increase the rate of free margin resection (R0) and reduce the risk of local recurrence. Even though single-agent gemcitabine and 5-FU have been validated in adjuvant and metastatic settings, the objective response was low (at around 10%), whereas combination chemotherapy exceeds a response rate of 30% in advanced disease. In metastatic PDAC, palliative FOLFIRINOX chemotherapy has been demonstrated to be effective (in terms of response rates and progression-free survival) and well tolerated. Interestingly, the response rate is increased by using more than two chemotherapeutic agents in advanced pancreatic cancer, justifying the use of an alternative neoadjuvant FOLFOX-based chemotherapy arm. PANACHE-01 is an open, non-comparative, randomised, multicentre Phase II study designed to assess the safety and efficacy of two modes of neo-adjuvant chemotherapy (FOLFIRINOX & FOLFOX) relative to the current reference treatment (surgery and then adjuvant chemotherapy) for resectable PDAC. Patients with immediately resectable PDAC (definition based on the NCCN's (American National Comprehensive Cancer Network 2014) latest guidelines) will be randomised to either pancreatectomy and adjuvant chemotherapy or 4 cycles of neoadjuvant chemotherapy with either FOLFOX or FOLFIRINOX. The patients in the neoadjuvant chemotherapy arms will receive postoperative chemotherapy for 4 months (8 cycles).
In 2015-2016, 224,390 cases were newly diagnosed with lung cancer in USA. Of all the cases, 83% are non-small cell lung cancer (NSCLC). Currently, the 5-year survival rate of NSCLC patients is 21%, and more than 25% of early stage NSCLC patients, who have undergone surgical treatment, will have a relapse or progression. Circulating tumor cells (CTCs), which shed from the primary tumor into the vasculature or lymphatics, can be regarded as a new prognostic factors of metastatic process. Thus far, CTCs-detection technologies can be divided into epithelial cell adhesion molecule (EpCAM)-based detection methods, e.g., the widely used CellSearch® and Adnatest®,and EpCAM-independent detection methods, e.g., ISET® and ScreenCell®. Herein, the investigators used a newly established approach, i.e., CanPatrolTM to detect CTCs in early stage lung Adenocarcinoma cases. The investigator aim to explore whether CTCs detection prior to surgery can be contributive to the early diagnosis, or may help to predict the prognosis and guide the treatment strategy of early stage lung Adenocarcinoma.
To investigate the clinical application value of laparoscopic radical right hemicolectomy using the caudal-to-cranial approach versus the medial-to-lateral approach by prospective randomized controlled clinical study.
This randomized phase II trial studies how well androgen receptor antagonist ARN-509 works with or without abiraterone acetate, gonadotropin-releasing hormone agonist, and prednisone in treating patients with high-risk prostate cancer undergoing surgery. Androgen can cause the growth of prostate cancer cells. Hormone therapy using androgen receptor antagonist ARN-509, abiraterone acetate, and gonadotropin-releasing hormone analog (GnRH agonist) may fight prostate cancer by lowering the levels of androgen the body makes. Prednisone may either kill the tumor cells or stop them from dividing. Giving androgen receptor agonist ARN-509 with or without abiraterone acetate, GnRH agonist and prednisone may work better in treating patients with prostate cancer.
