Filter by:The role of radiotherapy in metastatic cancer has historically been limited to palliation while metastasectomy or radiofrequency has emerged as playing a major role in disease control. Although resection is the standard of care for liver metastasis, 80-90% of patients are not resectable at diagnosis in particular because of the presence of oligometastases. Factors that favour a truly oligometastatic state include a long latent interval between the treatment of the primary tumor and the appearance of metastases. Oligometastatic cancer is a very heterogeneous disease with respect to several factors including the location of the primary tumor. With the advent of extracranial stereotactic body radiation therapy (SBRT), higher biological equivalent doses can be safely delivered in 3 to 5 fractions, thus potentially ablating all the tissue in the treated area while protecting more efficiently the hosting organ and healthy tissues surrounding the tumors. In patients with liver oligometastases, in-field local control rates at 2 years range from 70% to 90% with less than 5% severe grade 3 or higher toxicity rates. Retrospective studies indicate that roughly 20% of the patients remain disease-free 2 to 4 years after SBRT. For patients treated with SBRT some authors found that half of the patients had either no metastatic progression or very little progression in terms of number and site of metastases. The patterns of failure after SBRT for oligometastases in one organ showed that 73% of patients eventually developed new metastases with higher than 80% occurring as new metastases in the same index organ. These findings support the idea of an oligometastatic state in which aggressive local therapy could improve progression-free survival (PFS). With this phase III study, we sought to evaluate the impact of SBRT on PFS at 2 years in patients with synchronous or metachronous liver-only oligometastases from colorectal cancers patients after a first line chemotherapy for metastatic disease but not having progressed during first line chemotherapy and up to 1 year
This is a controlled, open-label, randomized phase- II trial (1:1 randomization) investigating 5-FU + aflibercept and 5-FU + oxaliplatin in elderly and frail elderly patients with mCRC scheduled to receive first line treatment.
This study investigates the feasibility and efficacy of an Internet-delivered intervention for the sexual and intimate re-adjustment of couples in which one partner is living with a temporary or permanent ostomy (e.g., colostomy, ileostomy, urostomy) following treatment for colorectal and/or bladder cancer. The two session intervention will be delivered via online videoconferencing and will focus on facilitating couples' communication around their sexual and intimate relationship. Exercises from sex therapy will be used to scaffold conversations about motivations for having sex, intimacy and sensual pleasure, and relational strengths for coping. The intervention aims to enhance couples' ability to cope with the changes in their sexual and intimate relationship. A group of couples receiving written educational material only will be used as a comparison group to measure change in sexual and intimate adjustment over time.
This is a Phase 1/2 open-label, multi-center, multi-national study with an initial dose escalation part to determine the RP2D of MCLA-158 single agent in patients with mCRC. The dose escalation part has been completed and the RP2D will be further evaluated in an expansion part of the study. Cohorts of selected solid tumor indications for which there is evidence of EGFR dependency and potential sensitivity to EGFR inhibition will be evaluated including head and neck cancer. The study will further assess the safety, tolerability, PK, PD, immunogenicity, and anti-tumor activity of MCLA-158.
This study was conducted to advance new treatment for patients with metastatic or locally advanced cancers expressing Neurotensin receptor 1 (NTSR1). This study was the first time the investigational drug called 177Lu-3BP-227 was administered to patients under controlled conditions of a clinical study. The purpose of this study was to evaluate how safe the investigational drug is as well to verify how well it is tolerated by patients after several intravenous administrations. In addition, the effect of the study drug on tumoral lesions and how it distributes throughout the body and at which rate it is removed from the body was evaluated. Since 177Lu-3BP-227 is a radio-labelled drug, it also measured how the emitted radiation is distributed throughout the body (dosimetry). The study consisted of a phase I dose escalation part. The study originally planned to include a phase II study however due to early termination (not due to safety concerns) the study did not progress to phase II and was stopped during phase I. For the phase I dose escalation part, it was anticipated that approximately 30 subjects will be included, in up to six escalation steps. No expansion cohorts were implemented.
There is a critical need for physical activity interventions in colorectal cancer (CRC). The investigators have developed a digital health physical activity intervention, Smart Pace, which includes a wearable tracker (Fitbit) and text messaging and aims to have patients build up to 150 min/wk of moderate activity. In this study, the investigators propose to expand and improve Smart Pace, including: 1) enrolling patients during chemotherapy; 2) tailoring text messages to individual preferences and treatment timing; and 3) adding resources to support home-based exercise. The study is a 12-week pilot randomized controlled trial (RCT) to evaluate the feasibility of this novel digital health physical activity intervention among 48 CRC patients on chemotherapy. The specific aims are to: 1) Determine the feasibility of the intervention via adherence and attrition, and determine the acceptability of the intervention via questionnaires and semi-structured interviews . 2) Estimate the effect of the intervention vs. usual care on physical activity, QOL, and symptoms at 12-weeks . And 3) Explore the impact of the intervention vs. usual care on fitness, weight, waist circumference, and blood pressure at 12-weeks.
Determine whether the administration of Visbiome after colorectal surgery has any effect on anastomotic leak and local recurrence
BACKGROUND: Colorectal cancer (CRC) and its treatment affect CRC survivors' quality of life (QoL), emotional distress and activities of daily living (ADL). It is assumed that occupational therapy interventions based on cancer education may be a feasible approach. Aim To examine the effect of using cancer education based on healthy lifestyle by occupational therapist on QoL, emotional distress, ADL and healthy lifestyle behaviors in CRC survivors. Methods Participants with CRC were designed as a two-group controlled trial, and a single-blind randomized controlled trial was conducted. These participants were randomly assigned to either an OT intervention or a non-intervention group (in a 1:1 ratio). Those participants in the OT intervention group were given a consultation based on a CRC education handbook by an occupational therapist for discharge preparation and on 1-month, 3-month follow-up clinic; the non-intervention group participants were given a CRC education handbook (the same handbook) only for discharge preparation. The primary outcome was the change in QoL measured using WHOOQOL-BREF. Secondary outcomes were changes in emotional distress, ADL and healthy lifestyle behaviors. Outcomes were examined in baseline (discharge preparation), 1-month and 3-months follow-up clinic.
Interventional, prospective, randomized (1:1), controlled, open label, multicenter phase IIb study in patients with advanced metastatic colorectal cancer. The scope of the trial is to evaluate overall survival of either regimen (TAS102 +/- Ramucirumab) and evaluate safety and tolerability.
This is a prospective, multi-center, blinded feasibility study. The objective of this study is to test the feasibility of the detection of tumor DNA of a variety of tumors in peripheral blood using a novel process for the detection of circulating tumor DNA (ctDNA).
