We performed a retrospective data analysis of patients with synchronously metastasized colorectal cancer, comparing the histological response on the primary tumour to chemotherapy combined with either vascular endothelial growth factor (VEGF) or epidermal growth factor receptor (EGFR) inhibition.
This is a Phase 1, multiple dose, ascending dose escalation study; to define a MTD/RD and regimen consisting of a first "priming" dose and escalated subsequent doses of XmAb18087; to describe safety and tolerability; to assess PK and immunogenicity; and to preliminarily assess anti-tumor activity of XmAb18087 in subjects with advanced NET or GIST. The study will enroll dosing cohorts to establish a MTD/RD and regimen in subjects with advanced NET or GIST, then enroll additional subjects into separate NET and GIST expansion cohorts to collect additional data on safety and potential efficacy of XmAb18087.
This study evaluates the impact of Endorings™ assisted colonoscopy on the number of polyps detected per patient compared to standard colonoscopy without use of EndoRings™. Half of the participants will receive EndoRings™ assisted colonoscopy, while the other half will receive standard colonoscopy.
Communication is an important component of comprehensive cancer care impacting patient satisfaction, adherence, and quality of life. The wide array of issues addressed in cancer clinical interactions makes communicating about a broad range of topics (including quality of life, communication, symptom control, complementary/alternative therapies, costs, treatment burden, prognosis, anxiety, side-effects, sexual function, palliative care options, etc.) especially interesting and potentially challenging. Some of these topics may not be routinely addressed in the clinical interaction or may require consultative support from other members of the comprehensive cancer care team. One frequently overlooked critical element in research on communication between cancer clinicians, their patients, and their primary care clinicians is describing real-time consultations between patients and their clinicians. These interactions provide rich material for assessing key psycho-social dynamics and identifying issues that patients find important in their care. In order to devise systems of care that optimize the patient experience, it is critical that clinicians and researchers understand, appreciate, and systematically characterize the richness and complexity of the decision-making process in routine cancer consultations between cancer patients and their treating clinicians. This study seeks to assess the patient experience in cancer care by observing patients and their physicians in their clinical interactions and following them for several months to see how their care went. By describing in-depth the conversations and experiences of patients in these clinical interactions, this study will lay the foundation for practice-based interventions to optimize patients' interactions with their cancer care teams.
The investigators hypothesize IXO chemotherapy will have an improvement in response rate and acceptable toxicity for uncurable metastatic gastric cancer compared to historical controls.
Picoplatin is a new platinum-based chemotherapy drug that has been studied in a variety of cancers. Phase 1 and 2 studies have demonstrated that picoplatin may be effective in patients whose cancer returns or does not improve after treatment with chemotherapy. In these studies, picoplatin was administered intravenously. A capsule containing picoplatin has been formulated. This study will investigate the activity of the oral capsule in humans. Participants with advanced solid tumors will be enrolled.
This study will determine which of the two following treatment regimens provides greater benefit to patients with peritoneal carcinomatosis (gastrointestinal cancer that has spread throughout the abdomen): - Surgical removal of tumors plus heated chemotherapy during surgery, followed by one dose of chemotherapy 7 to 12 days after surgery, followed 3 weeks later by 4 months of chemotherapy; or - Surgical removal of tumors followed by 4 months of chemotherapy, starting 1 month after surgery. Patients 18 years of age and older with peritoneal carcinomatosis may be eligible for this study. Candidates are screened with a medical history, physical examination, and blood tests; chest X-ray and computed tomography (CT) scans; review of pathology slides; electrocardiogram (EKG), bone scan, and brain magnetic resonance imaging (MRI), as needed; and laparotomy. Laparatomy is a surgical procedure in which an incision is made in the abdomen to look at the amount and location of tumors in the abdominal cavity. Patients whose surgery reveals that the tumors cannot be removed are taken off study. Those eligible for the study have their tumors removed during this screening laparotomy as part of the study procedure, as follows: All participants undergo laparotomy and removal of as much tumor as possible, as described above. Patients are then randomly assigned to one of two treatment groups: - Group 1 - During laparotomy, after tumor removal, patients receive continuous hyperthermic peritoneal perfusion (CHPP) with the anti-cancer drug cisplatin. For CHPP, the cisplatin solution is heated and delivered to the abdomen through a catheter (plastic tube), washed through the abdomen for 90 minutes, and then drained out of the body through another catheter. At the close of surgery, a small catheter, called a Tenckhoff catheter, is left in the abdomen and brought out through the skin. Between days 7 and 12 after surgery, one dose of fluorouracil and paclitaxel chemotherapy is delivered through this catheter. The catheter is removed following complete recovery from surgery and the patient is discharged from the hospital. Four to 6 weeks after the surgery, patients have CT scans of the chest, pelvis, and abdomen, and then begin intravenous (IV, through a vein) chemotherapy with oxaliplatin, 5-fluorouracil (5-FU), and leucovorin. The chemotherapy is given in 4-week courses as follows: oxaliplatin on day 1, infused over 2 hours through a vein in the arm or neck; leucovorin on days 1 and 2, infused over 2 hours, followed by 5-fluorouracil over 22 hours; leucovorin and 5-FU repeated two weeks later on days 15 and 16. This regimen is repeated two weeks later. Between each week of chemotherapy is a week break. A course of chemotherapy consists of 28 days (two weeks of chemotherapy and two 1-week breaks). Patients may receive up to four courses (total of 16 weeks) unless their disease progresses or they cannot tolerate further doses. Doses of the chemotherapy can be reduced if the side effects are too severe. - Group 2 - Patients follow the same procedure as those in Group 1 for laparotomy, CT imaging, and IV chemotherapy with oxaliplatin, 5-fluorouracil, and leucovorin. They do not receive CHPP or chemotherapy into the abdomen. All patients undergo repeat imaging tests six weeks after surgery and at the conclusion of the intravenous (IV) chemotherapy. They return for a physical examination and CT scans every three months for the first year, every four months for the next two years, and then every six months for up to five years after treatment. They are also asked to complete quality of life questionnaires before and after surgery, at the completion of chemotherapy, and at every follow-up visit.
