Metastases

Unblinded, randomized study of 5-fraction LATTICE radiotherapy (20 Gy with an SIB to 66.7 Gy in 5 fractions) versus moderately dose-escalated palliative radiation (25 Gy in 5 fractions)

Palliative radiation is effective for controlling or preventing symptoms such as pain, bleeding, dyspnea, and cord compression. Recently, studies have shown that additional dose escalation may result in superior local control. The investigators propose a phase II single arm trial to evaluate a novel high-dose radiation regimen, which will be 27 Gray in 3 fractions with dose escalation within the tumour (Hi-D).

The ZANGEA trial is a open-label, single arm, multicenter phase II trial assessing the efficacy of zanidatamab in combination with pembrolizumab and chemotherapy in patients with metastatic gastroesophageal adenocarcinoma (GEA). The patients need to be previously untreated in the palliative setting and tested positive for HER2 and PD-L1.

A prospective, interventional study evaluating the safety of Y-90 TARE for tumor control of the right side and induction of left liver hypertrophy as part of a planned single-stage or two-stage hepatectomy for patients with CLM and insufficient FLR at the time of presentation.

This study evaluates a non-cationic peptide-CD47 siRNA nanocomplex for refractory advanced solid tumors. The candidate blocks the CD47-SIRPα "don't eat me" signal, repolarizes tumor-associated macrophages, and restores antitumor immunity. Using a 3+3 dose-escalation design (25, 50, 100 μg), the investigators aim to define the MTD and RP2D, providing a novel therapeutic approach and clinical evidence for siRNA drug development.

This study evaluates whether comprehensive local consolidative therapy added to continued sintilimab plus lenvatinib improves survival compared with continued sintilimab plus lenvatinib alone in patients with oligo-extrahepatic metastatic hepatocellular carcinoma. All enrolled participants receive induction treatment with sintilimab plus lenvatinib for 4 cycles. Participants who achieve disease control and are confirmed by central multidisciplinary review to be feasible for complete consolidation are randomized in a 1:1 ratio to receive either comprehensive local consolidative therapy followed by continued systemic therapy or continued systemic therapy alone. The primary outcome is overall survival.

The primary objective of the study is to evaluate the effects of exercise on physical function, physical fitness, and body composition, with the main components including muscular strength, cardiorespiratory fitness, muscle mass, fat mass, and fat-free mass. The secondary objectives are to examine exercise adherence and the effects of exercise on health-related quality of life (HRQoL), cancer-related fatigue, and sleep quality. Additionally, the feasibility and safety of the exercise program will be assessed.

The primary research purpose is to evaluate the diagnostic efficacy of 68Ga-PSMA PET in metastatic lesions of locally advanced and advanced renal cell carcinoma, and to compare with that of enhanced CT. The second purpose is to evaluate whether 68Ga-PSMA PET can change the treatment decision of patients with locally advanced and advanced renal cell carcinoma

For early breast cancer patients, breast-conserving surgery and sentinel lymph node biopsy have emerged as the cornerstone of precision oncology, harmonizing oncologic efficacy with the preservation of breast cosmetics and axillary function. However, conventional margin evaluation relies on subjective experience, leading to positive margin rates of 15%-50% Additionally, sentinel lymph node biopsy faces inherent technical limitations, including prolonged procedural time and significant false-negative rates in detecting micro-metastases. To overcome these challenges, the investigators will introduce a stable "sandwich" EpCAM-targeted surface-enhanced Raman spectroscopy (SERS) detection system to provide rapid evaluation of surgical margins and sentinel lymph node (SLN) metastasis status. In brief, a portion of resected tissue will be immediately homogenized by grinding, and the tissue homogenate will then be analyzed using this detection system to determine its histological characteristics. Pathological confirmation will further validate the method. This approach aims to improve the accuracy and efficiency of intraoperative assessment of breast-conserving surgical margins and SLN status, thereby effectively reducing local recurrence rates and complications.

The study is being done to determine if stereotactic ablative radiotherapy (SABR) can control tumour growth for patients with metastatic breast cancer. Secondary objectives will be overall survival, progression-free survival and time to switch of next line of systemic therapy. Radiation-related adverse events will be assess, with a specific focus on dermatitis, lymphedema and brachial plexopathy. The exploratory objective is to correlate toxicities and outcomes with peripheral blood biomarkers and circulating tumor DNA to potentially help predict responses in future patients receiving combined therapy.

Accurate evaluation of tumor boundaries in breast-conserving surgery is closely associated with reducing the second operation of patients. Meanwhile, accurately assessing sentinel lymph node (SLN) metastasis is crucial for determining the extent of axillary lymph node dissection (ALND) and minimizing complications. Near-infrared-II (NIR-II) fluorescence imaging using molecular agents has shown promise for in situ imaging during resection. However, very effective probes can be applied to clinical trials up to now, which limits the clinical application of fluorescence imaging. Here we developed a new technology that can quickly differentiation between cancer and para-cancer tissue as well as metastatic and normal sentinel lymph nodes(SLN). In brief, the fresh tissues were incubated with the probe immediately after intraoperative resection and imaged to identify the tumor area and distinguish the metastatic status of SLN. The accuracy of fluorescence imaging was confirmed by pathological diagnosis.

This prospective national multicenter observational and interventional study aims to assess the longitudinal disease trajectory of patients with oligometastatic disease (OMD) who receive local metastasis-directed therapy. Patients with any category of OMD from any non-hematological cancer are eligible for inclusion. Local ablative therapy (LAT) includes surgical metastasectomy, radiotherapy, thermal ablation, and electroporations. The primary objective is to assess the time to failure of LAT strategy in patients with OMD from any primary cancer treated with all LAT modalities.
