Filter by:This phase Ib/II study is a prospective, open-label, single arm, nonrandomized study of PEP503(radio-enhancer). There are 2 portions in this study. - Escalation phase (Part Ib): A 3 + 3 dose escalation study design will be adopted in this phase to identify the recommended injection volume of PEP503 for intratumor injection. - Expansion phase (Part II): Following the confirmation of the recommended volume of intratumor injection, 18 additional patients will be enrolled at the recommended volume level to evaluate for efficacy.
This phase II MATCH screening and multi-sub-trial studies how well treatment that is directed by genetic testing works in patients with solid tumors, lymphomas, or multiple myelomas that may have spread from where it first started to nearby tissue, lymph nodes, or distant parts of the body (advanced) and does not respond to treatment (refractory). Patients must have progressed following at least one line of standard treatment or for which no agreed upon treatment approach exists. Genetic tests look at the unique genetic material (genes) of patients' tumor cells. Patients with genetic abnormalities (such as mutations, amplifications, or translocations) may benefit more from treatment which targets their tumor's particular genetic abnormality. Identifying these genetic abnormalities first may help doctors plan better treatment for patients with solid tumors, lymphomas, or multiple myeloma.
This study will assess whether the Sienna+/Sentimag system, which involves a magnetic tracer, is effective in identifying the sentinel lymph node in rectal cancer and whether it is then feasible to remove this lymph node during surgery to locally excise early rectal cancer.
This pilot study will take place at Health Sciences North (HSN) in Sudbury. Patients will be identified and screened for inclusion into the study once referred to a general or colorectal surgeon for resection of their rectal cancer. This may occur before or after preoperative chemoradiotherapy (CRT) but randomization will take place after CRT.
The purpose of this study is to determine whether 18F-FDG-PET-CT and texture analysis of MRI performed 9 weeks after Neoadjuvant Chemo-radiotherapy in patients with locally advanced rectal cancer has the ability to identify patients with Complete Response.
The aim of the present study is to investigate whether curative chemoradiation of low rectal cancer is feasible, safe and effective in a multicenter study with results comparable to those of single center studies. Results from previous studies indicate that a considerable fraction of patients with low rectal cancer can be cured by a combination of radiation and chemotherapy alone and thus be spared from operation.
Metformin is an oral antidiabetic of the biguanide class derived from galega officinalis. Historical cohort of patients with diabetes have shown that diabetics on Metformin had a better chance of survival than diabetics not on Metformin. These observations have led to in vitro studies of metformin on cancer cells. It was thus demonstrated that Metformin has anti-proliferative properties. The aim of our study is to evaluate the efficacy of metformin in combination with neoadjuvant radiochemotherapy in the treatment of locally advanced rectal cancer.
TME (Total mesorectum excision) is the golden standard of radical resection for mid-low rectal cancer. However, the damage of pelvic autonomic nerve following with TME principle will lead to high incidence of urinary and sexual function disorder. PANP (pelvic autonomic nerve preservation) surgery played a role in decreasing incidence of urinary and sexual function disorder. However, 32%-44% patients still suffered from urinary and sexual function disorder when underwent open (O-PANP-TME) or laparoscopic PANP TME surgery (L-PANP-TME). In the early stage of work, the investigators performed preservation of Denovilliers' fascia in L-PANP-TME to discuss the protection of urinary and sexual function of male mid-low rectal cancer patients. The results showed that preservation of Denovilliers' fascia in L-PANP-TME significantly decreased incidence of urinary and sexual function disorder. In order to further confirm the early work, the investigators design a multicenter randomized controlled clinical trial to compare differences in urinary and sexual function protection and long-term outcomes between preservation and excision of Denovilliers' fascia in L-PANP-TME.
The purpose of this study is to evaluate the safety and efficacy of irreversible electroporation (IRE) for unresectable Rectal Neoplasms.
The purpose of this study is to evaluate the safety and efficacy of CT guided 125I seeds implant plus systemic chemotherapy for locally recurrent rectum cancer.
