Active clinical trials for "Neoplasm Metastasis"

With rapid advances in molecular oncology, the availability of preclinical in vitro cell models and in vivo animal models with specific genomic aberrations is critical for improved prediction of clinical outcomes in cancer patients. One of the most widely used preclinical models is conventional cell lines, such as the NCI-60 panel of cell lines;these cell lines are widely used in preclinical testing for novel targeted drugs, partially owing to the low expense and reduced labor associated with cell culture compared with other preclinical models, such as animal xenografts. However, recent studies have shown that accumulation of genetic aberrations in cancer cell lines occurs with increasing passage number. These models also lack the heterogeneity of tumors and do not exhibit a proper microenvironment, highlighting the limitations of cell-based models. Consistent with this, Johnson et al. demonstrated that in vivo activities of the cell lines within the NCI-60 panel did not closely correlate with corresponding human cancers. Therefore, to better preserve the genomic integrity and tumor heterogeneity observed in patients, patient-derived xenograft (PDX) models are being used more frequently. PDX is generated by directly transplanting freshly resected patient tumors into immunocompromised murine hosts with or without an intermediate in vitro culture step. This PDX model is an improvement over cell lines because it can provide both an appropriate tumor microenvironment and heterogeneity of tumor cells. However, the engraftment success rates and growth rates of implanted tumors are highly variable depending on the tumor type, possibly due to insufficient numbers of hematopoietic cells and/or ineffective microenvironmental cues in the mouse stroma. The extent to which tumor cells from freshly resected tumors are able to withstand mechanical stresses and xenotransplantation barriers is also unclear. Furthermore, the use of PDX models for application in clinical oncology is limited owing to the time required for PDX establishment (> 4 months) since most patients with refractory cancer live less than 1 year. Recently, PDC line models have been suggested as an alternative preclinical model to be used as a prediction tool for preclinical drug sensitivity. Therefore, in this study, the investigators aimed to overcome these potential barriers of pre-existing models by examining the capacity of PDC line models to recapitulate the histological and genomic features of primary patient tumors. In selected cases, the investigators screened drug sensitivity in vitro using PDC lines and compared the results with real-life clinical treatment outcomes.

Bone is a common site of metastasis for a range of malignancies. Bone metastases have the potential to cause significant morbidity including pain, impairment of ambulation and reduced functional independence. Previous research has shown that pathological fractures are observed in 9 to 29 percent of patients with long bone metastases, and a high proportion of these require surgical intervention to relieve pain and restore function. The goal of this study is to describe the clinical outcomes of patients with femoral metastases at high risk of pathological fracture. Patients referred for treatment of femoral metastases at high risk of fracture will be followed prospectively after undergoing with surgery (± post-operative radiotherapy), or radiotherapy alone. Patient and disease characteristics, ambulatory status and limb function will be documented before treatment. These Clinical outcomes of participants in each treatment group will be measured 6 weeks after treatment, and 3- and 6 months after enrolment, with particular reference to patient-reported outcomes relating to pain, ambulatory status, limb function and quality of life.

We initially selected a total of 1128 patients with primary gastric cancer who presented at Shandong Provincial Hospital between January 2018 and October 2022, and retrospectively collected their clinical and pathological data. And retrospectively analyzed preoperative baseline characteristics, preoperative laboratory tests, and postoperative pathological results for these patients

The aim of this study is to evaluate the efficacy and safety of apalutamide in combination with 89Sr as neoadjuvant therapy in prostate cancer with ≤10 bone metastases. The primary endpoint is PFS and the second endpoints are pCR, rPFS, PSA response, pain score, number and extent of bone metastases.

To evaluate the Safety and Efficacy of HIPEC Combined With Sintilimab for Gastric Cancer Patients with Peritoneal Metastasis.

This is a prospective, single-center observational clinical study aimed at the efficacy and safety of radiotherapy combined with PD-1 inhibitors and chemotherapy in the treatment of Chinese patients with symptomatic NSCLC with brain metastases.

This study is the first to explore the efficacy and safety of recombinant human adenovirus type 5 injection combined with PD-1 monoclonal antibody and nab-paclitaxel in the treatment of patients with liver metastases of melanoma, in order to provide a new method for the clinical treatment of melanoma. The model also provides reference and basis for other tumor treatments.

This phase I/II trial will investigate the use of the novel oral IRAK-4 inhibitor CA-4948 in combination with pembrolizumab therapy following stereotactic radiosurgery in patients with melanoma brain metastases (MBM). The investigators hypothesize that the addition of CA-4948 will reduce the rate of distant intracranial failure and reduce the need for subsequent radiation therapy. The investigators also propose that it will have a significant reduction in radiation necrosis and improve patient-reported symptoms and quality of life. This trial represents the first time an oral IRAK-4 inhibitor has been used in combination with aPD1 therapy in MBM and will yield valuable insight into its synergistic potential both in MBM and additional sites of metastases.

TRIPLET HCC is a phase II-III trial that assess the effectivness of addition of ipilimumab to the combination atezolizumab-bevacizumab, on global survival and response to the treatment, for patients with advanced or metastatic hepatocellular carcinoma. The theoretical duration of the study is 5 years. In the scope of this study, each patient will have 2 years of treatment and 2 years of follow-up from their enrollment date.

This is a phase II/III international multicentre randomized trial. Patients will be randomized in a 1:2 ratio between the standard of care (Arm 1) and SABR (Arm 2) to all sites of disease. The study will start as a phase II trial with an opportunity to convert to a phase III trial. The objective of this trial is to determine the impact of SABR on overall survival, progression-free survival, quality of life, and toxicity in patients with polymetastatic disease.
