Filter by:Background. About 20% of rectal cancers who underwent neoadjuvant treatment (neoCHT-RT) achieve a pathological complete response in the surgical specimen(ypT0); however, about 10% of ypT0 present metastatic nodes (N+). Although seldom analyzed, ypT0N+ identification could be crucial in order to tailor treatments. Hypotheses. The two hypotheses to test are if we can identify ypT0N+ and if N+ is an independent prognostic factor. Aim 1. To create a large Database (DB) of ypT0. Aim 2. To compare ypT0N0 vs ypT0N+ with respect of their clinical/radiological/molecular features. Aim 3. To investigate long term results. Preliminary Study. Dr Lorenzon is the PI of an Italian retrospective multicentric study conducted on 260 ypT0 focused on treatment and outcomes. Design. The PI will operate in partnership with the European Society of Surgical Oncology (ESSO). A DB will be used by ESSO-affiliated centres for collecting the clinical, pathological and radiological data of ypT0N0/N+, previously treated (last 5 years) and prospectively enrolled (6 months + 2 years of follow-up); each centre will provide a junior (<40 yrs) member for data collection and a senior investigator .for data validation; all the analyses will be centralized by the PI. ypT0N0 and ypT0N+ will be compared for the clinical/pathological variables, for the gene expression profiles of pre-neoCHT-RT biopsies (grant requested). Uni-multivariate survival analyses (end-points: OS, DFS, DSS) will be conducted at 2 years of follow-up. Impact. This is the first study aimed to investigate ypT0N+ features; their accurate identification could lead to treat safely thousands of ypT0N0/year with local excisions leaving major surgery for N+ patients. Results will change practice and reduce considerably health-related costs; moreover, the molecular profiles will open new frontiers of research.
Project HERO is a 12-week study of the efficacy of Body Mind Training (BMT) for reducing fatigue in male cancer survivors. This 3-arm randomized clinical trial will examine inflammatory biology and selected gene-expression pathways that are hypothesized to contribute to the intervention's effect.
All the preoperative biopsies of patients suffering colorectal cancer (CRC) will be immunohistochemically stained with a pancytokeratin marker to detect Tumor buds. then, the intratumoral buds (ITB) in the densest Region of Tumor buds, namely the "hot spot" will be counted. Subsequently, the probability of N stage (lymphnodes), M stage (metastases) and disease free survival (DFS) will be calculated based on an existing logistic Regression model already developed by our previous retrospective work. Additionally, a Standardisation of ITB using a well- established Software will develop an algorithm which will help to eliminate inter- observer variability of Tumor budding Counts.
Reflexion on the therapeutic strategies to implement in patients at the end of life is advancing rapidly in France. However, beyond the choices presented to patients, sometimes even the decision to carry on, to limit or to stop treatments is also questioned. This decision is subjective; it is influenced by the patient's representation system (emotions, beliefs, values, practices, etc). In addition, even though he or she is the focus of the decision, the patient is not alone; other actors, accompanying the patient, play an important role in the final decision making. These actors, namely the doctors and close relatives, are also influenced in their decision making. This coexistence of representation systems may interfere with objective indicators that help in decision making (functional, clinical and biological) or with the knowledge acquired by doctors in their training and may complicate the decision-making process.
Anastomotic leakage (AL) is considered the commonest major complication after surgery for rectal cancer. Transanal tube drainage role in the prevention of AL is still debatable.
This phase I trial studies the side effects and best dose of trametinib and trifluridine and tipiracil hydrochloride in treating patients with colon or rectal cancer that has spread to other places in the body (advanced/metastatic) or cannot be removed by surgery. Trametinib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Drugs used in chemotherapy, such as trifluridine and tipiracil hydrochloride, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Giving trametinib and trifluridine and tipiracil hydrochloride may prevent cancer cells from dividing and work better in treating patients with colon and rectal cancer.
Lymph node status is of major prognostic importance in non-metastatic rectal cancer. For oncological reasons, central arterial ligation of the inferior mesenteric artery (IMA) is suggested. However, there is no conclusive evidence presented for this procedure. This study aimed at investigating the localisation of lymph node metastases and the role of central versus peripheral arterial ligation of in rectal cancer specimens.
This phase I trial studies the best dose and side effects of talimogene laherparepvec in combination with 5-fluorouracil, leucovorin, oxaliplatin, capecitabine, and chemoradiation before surgery in treating patients with rectal cancer that has spread from where it started to nearby tissue and lymph nodes. Drugs used in immunotherapy, such as talimogene laherparepvec, may stimulate the body's immune system to fight tumor cells. Drugs used in chemotherapy, such as 5-fluorouracil, leucovorin, oxaliplatin, and capecitabine work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Radiation therapy uses high-energy x-rays to kill tumor cells and shrink tumors. Giving talimogene laherparepvec, 5-fluorouracil, leucovorin, oxaliplatin, and capecitabine and chemoradiation before surgery may make the tumor smaller and reduce the amount of normal tissue that needs to be removed.
This trial is investigating the inclusion of avelumab post long-course chemo-radiotherapy in patients with resectable locally advanced rectal cancer. It is hypothesised that this may enhance the pathological and imaging response rates whilst potentially reducing the relapse rates. Participants will receive standard long course chemoradiotherapy (LCCRT) treatment with radiotherapy and 5-fluorouracil (5 FU)/Capecitabine for 6 weeks, this then followed by 4 cycles of Avelumab and then surgical resection. The trial will measure disease response just prior to surgery and participants will be followed up for a minimum of 18 months (from study entry) and up to 42 months.
This phase I trial studies the side effects and best dose of trifluridine/tipiracil hydrochloride combination agent TAS-102 (TAS-102) when given together with radiation therapy in treating patients with rectal cancer that has come back, spread to other places in the body, or cannot be removed by surgery. Drugs used in chemotherapy, such as TAS-102, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Radiation therapy uses high-energy x-rays to kill tumor cells and shrink tumors. Giving TAS-102 with radiation therapy may kill more tumor cells.
