Filter by:This phase II trial studies the effect of APL-2 when given in combination with either pembrolizumab or pembrolizumab and bevacizumab compared with bevacizumab alone in treating patients with ovarian, fallopian tube, or primary peritoneal cancer that has come back (recurrent) and a buildup of fluid and cancer cells (malignant effusion). APL-2 may limit tumor progression, decrease malignant effusion production, and improve the immune system's response against cancer cells. Immunotherapy with monoclonal antibodies, such as pembrolizumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Bevacizumab is a monoclonal antibody that may interfere with the ability of tumor cells to grow and spread. Giving APL-2 together with either pembrolizumab or pembrolizumab and bevacizumab may work better in treating patients with ovarian, fallopian tube, or primary peritoneal cancer and malignant effusion compared to bevacizumab alone.
Background The current management on rectal cancer based on TNM staging has some limitations. In locally advanced rectal cancer after neoadjuvant therapy the persistence of a complete response to therapy cannot be accurately predicted by the simple tumor regression grade. The current guidelines recommend the complete rectal resection with a total mesorectal excision. The implications for patients' quality of life are evident even in case of sphincter sparing surgery. Moreover, in both cases the cancer sample available for the analysis can be small or inexistent. Hypothesis The main hypothesis underlying our research is that the aggressiveness of rectal cancer is determined by the complex interactions between the malignant cells and their immune microenvironment. The second hypothesis is that relevant trace of this cross talk between tumor cells and immune microenvironment can be detected in the normal mucosa surrounding the cancer according to the concept of field cancerization. Aims The aim of this project is to analyze the healthy rectal mucosa surrounding the cancer to identify traces of immunosurveillance mechanisms and of field cancerization and to use them to obtain a composite prognostic test to predict recurrence after complete response at neoadjuvant therapy in case of locally advanced rectal cancer. Experimental Design This prognostic test will be constructed on the combinatory analysis of the transcriptome, immune and epithelial cells cross-talk, immune checkpoints and miRNA expression in normal rectal mucosa surrounding cancer. The project aim is to identify, among locally advanced rectal cancer, those with sustained complete response to neoadjuvant chemo/radiotherapy. The study is articulated in two steps. In step A, we will retrospectively analyze archival tissue samples in order to identify the most performing biomarkers; in step B, we will validate the prognostic performance of the markers identified in phase I through a prospective analysis of rectal mucosa specimen.
Real World Data (RWD) obtained from real clinical sites is data obtained after administering a drug to patients with different characteristics in daily practice, and Real World Evidence (RWE) is established based on RWD. It is possible to overcome the disadvantage of RCT, which cannot reflect all the various variables in the actual clinical field as it is conducted for only subset of patients. Researchers planned to prospectively collect RWD of ramucirumab/paclitaxel combination therapy as 2nd-line chemotherapy in patients with locally advanced unresectable or metastatic gastric or gastroesophageal junction adenocarcinoma.
Pancreatic cancer (PC) is expected to be the third leading cause of cancer death in Canada in 2019 [1]. Localized pancreatic cancer may be classified as resectable, borderline resectable, or locally advanced. To date, radical surgical resection and adjuvant treatment provide the greatest chance of long-term disease control and overall survival [2,3]. Despite this favourable group, the five-year survival rates are approximately 20% [4]. Neoadjuvant therapy (NAT) for resectable pancreatic cancer (RPC) has been widely accepted for the management of borderline resectable PC (BRPC) to increase the likelihood of achieving R0 resection [4-7]. However, to date, NAT for RPC is still an area of debate due to the lack of large prospective randomized controlled trials that compare this technique to surgery plus adjuvant therapy. Stereotactic ablative radiation therapy (SABR) uses modern radiotherapy planning and targeting technologies to precisely deliver larger, ablative doses of radiotherapy in 1-8 fractions. The role of SABR in RPC has yet to be fully established. The typical goal of radiation therapy in the neoadjuvant setting is to improve local control and increase R0 resection rates. However, there are still concerns about the timing of surgery after SABR and any implementation should be evaluated for safety. Treatments inherently changes the tumour and can cause immunomodulatory effects. SABR has anti-neoplastic effects both directly on the tumour and by its interactions with the immune system. In addition to the direct DNA damage, it is felt that SABR also increases T-cell priming, antigen production and presentation. Pancreatic cancer's dense, collagen rich stroma has prevented patients from receiving the same benefits of checkpoint inhibition that have been achieved in other cancer sites.
ABSTRACT Background The current management on rectal cancer based on TNM staging has some limitations. In early rectal cancer T stage can be not sufficient to predict the nodal status and, in locally advanced rectal cancer after neoadjuvant therapy the persistence of a complete response to therapy cannot be accurately predicted by the simple tumor regression grade. For both cases the current guidelines recommend the complete rectal resection with a total mesorectal excision. The implications for patients' quality of life are evident even in case of sphincter sparing surgery. Moreover, in both cases the cancer sample available for the analysis can be small or inexistent. Hypothesis The main hypothesis underlying our research is that the aggressiveness of rectal cancer is determined by the complex interactions between the malignant cells and their immune microenvironment. The second hypothesis is that relevant trace of this cross talk between tumor cells and immune microenvironment can be detected in the normal mucosa surrounding the cancer according to the concept of field cancerization. Aims The aim of this project is to analyze the healthy rectal mucosa surrounding the cancer to identify traces of immunosurveillance mechanisms and of field cancerization and to use them to obtain a composite prognostic test to predict nodal metastasis in early rectal cancer and recurrence after complete response at neoadjuvant therapy in case of locally advanced rectal cancer. Experimental Design This prognostic test will be constructed on the combinatory analysis of the transcriptome, immune and epithelial cells cross-talk, immune checkpoints and miRNA expression in normal rectal mucosa surrounding cancer. The aim is to predict the presence of nodal metastasis in patients with early rectal cancer. In step A, we will retrospectively analyze archival tissue samples in order to identify the most performing biomarkers; in step B, we will validate the prognostic performance of the markers identified in phase I through a prospective analysis of rectal mucosa specimen. Expected Results The anticipated outcome of this project is to generate one or different combination of markers to optimize rectal management and to predict rectal cancer patients outcome more accurately than traditional TNM staging or tumore regression grade. We expect to obtain a prognostic test from normal tissue that accurately predicts rectal cancer behavior even in case when the tumor samples are scarce (early rectal cancer) or absent (complete response to therapy) to avoid unnecessary total rectal excision. Impact On Cancer An immunoscore specific for rectal cancer may predict tumor progression and clinical outcome more accurately and may contribute to better design a personalized therapeutic algorithm. Moreover, nowadays patients with early rectal cancer without nodal involvement and patients with potential complete response to neoadjuvant therapy still undergo total rectal excision which is a risky procedure that impairs quality of life. The use of this new prognostic test may make possible to adopt a minimally invasive approach or even simple observation if nodal involvement or residual disease are reasonably excluded.
This is a Randomized, Active Controlled, Comparative, Open-Label, Multi-Center, Phase 3 clinical study to compare the efficacy, safety, and pharmacokinetics of leuprolide acetate for injection 3.75mg (depot) of two brands (Luprodex and Lucrin) administered in subjects with advanced adenocarcinoma of the prostate. Approximately 168 subjects (males )of age above 18 years fulfilling the eligibility criteria will be enrolled. The IP will be given as a monthly dose for two cycles on day 0 and day 28. The pharmacokinetic analysis will be done for 12 patients receiving Luprodex. The primary and secondary outcomes will be captured on days as per protocol. Adverse events will be noted for safety evaluation.
This will be a phase I/II trial examining the safety and tolerability of pre-operative mFOLFIRINOX in combination with peri-operative oral hydroxychloroquine (FHQ) in the treatment of subjects with adenocarcinoma of the pancreas. Subjects will be staged prior to protocol entry by contrast-enhanced helical abdominal CT scan done using a pancreas mass protocol or EUS. Eligible subjects with biopsy-proven, resectable pancreatic adenocarcinoma without evidence of venous or arterial involvement on CT scan receive HCQ orally in combination with mFOLFIRINOX prior to surgery. Hydroxychloroquine will begin with the first dose of mFOLFIRINOX and continue for 2 weeks post-operatively. Three to six weeks after the last dose of mFOLFIRINOX, patients will undergo surgical exploration and pancreatectomy if technically feasible and all toxicities have resolved. Pathologic specimens will undergo detailed histopathologic and immunohistochemical evaluations with particular attention to the six surgical margins of resection: the bile duct margin (for Whipple specimens), the margin of pancreatic transection, the retroperitoneal margin, the proximal and distal duodenal margins (for Whipple specimens), and the portal vein margin along the pancreatic head (for Whipple specimens) or medial pancreas (for distal pancreatectomies). Tissue specimens will be stored at -80C for future correlative studies of autophagy and tumor response to protocol therapy. Ten to fourteen weeks following completion of successful surgical removal of their tumor, subjects will undergo repeat staging studies per standard of care. Subjects will pursue standard of care adjuvant therapy options at the discretion of their physician.

To compare transhiatal / transabdominal approach with thoracoabdominal approach for Siewert II adenocarcinoma of esophagogastric junction
Despite lymph node involvement (LNI) being one of the main prognostic factors in patients with prostate cancer (PCa), pelvic lymph node irradiation remains debated, possibly due to an insufficient selection of patients. Significant advances in LNI risk modelling have been achieved with the addition of visual interpretation of magnetic resonance imaging (MRI) data, but it is likely that quantitative analysis could further improve prediction models. In this study, the investigators aimed to develop and internally validate a novel LNI risk prediction model based on radiomic features extracted from pre-operative multimodal MRI.
