TMV Vaccine Alone or With Toripalimab-tpzi for Recurrent Head and Neck Squamous Cell Carcinoma

The goal of this clinical trial is to learn if an experimental, personalized cancer vaccine called TMV vaccine is safe and to find the best dose to study in future trials. The study includes adults with head and neck squamous cell carcinoma that has come back in or near the same area after earlier treatment, and who are planning to have surgery to remove it. The study will also test the vaccine together with toripalimab-tpzi, an approved immunotherapy drug. The TMV vaccine is made from each participant's own tumor tissue. Small particles taken from the surface of the tumor cells have 2 immune-boosting proteins added to them, to help the immune system recognize and attack the cancer. The main questions it aims to answer are: * Is the TMV vaccine safe, and what medical problems do participants have after receiving it? * What is the best dose of the TMV vaccine to use in future studies? * Is the TMV vaccine safe when given together with toripalimab-tpzi before and after surgery? The study has 2 parts. In Part 1 (Phase 1a), participants will: * Have tumor tissue collected during their planned surgery, which is used to make their personal vaccine * Receive the vaccine as small injections into the skin every 2 weeks for 3 doses, starting after they recover from surgery * Visit the clinic about once a week for 8 weeks for checkups, blood tests, and safety monitoring * Have scans every 3 months and be followed for up to 3 years The first participants will receive the lowest dose. Later groups will receive higher doses only if the lower dose is found to be safe. In Part 2 (Phase 1b), participants whose tumors test positive for a marker called PD-L1 will: * Have a biopsy to collect tumor tissue for their personal vaccine * Before surgery, receive 2 doses of the vaccine and up to 2 doses of toripalimab-tpzi through a vein * After surgery, receive 1 more dose of the vaccine and continue toripalimab-tpzi every 3 weeks for up to 1 year * Have regular checkups, blood tests, and scans, and be followed for up to 3 years Researchers will also study blood and tumor samples to learn how the immune system responds to the vaccine.

Irreversible Electroporation (IRE) for Treating Recurrent Pelvic Tumors (PELFIRE Study)

The goal of this single-center observational cohort study, based on a registry combining retrospectively and prospectively collected data, is to investigate the short- and long-term effects of irreversible electroporation (IRE) in men and women over the age of 18 who receive IRE for recurrence of pelvic tumors not suitable for other local treatment options such as surgery, thermal ablation, and radiotherapy. The main question it aims to answer is whether IRE is safe in this population, and secondarily, whether it is effective in controlling local tumor recurrence.

Methylation Profile Test (Methylscape) in Body Fluids for Multi-Cancer Detection and Monitoring in Colombia

DNA methylation changes occur early and broadly during carcinogenesis. Methylscape is a rapid assay that detects global DNA methylation patterns in body fluids (blood, urine, and saliva) and may detect a cancer signal and predict the cancer signal origin (CSO) from a single fluid sample, using the differential interaction between methylated and unmethylated DNA and gold nanoparticles. This prospective observational study evaluates the diagnostic performance (sensitivity and specificity) of the Methylscape test in Colombian patients with various biopsy-confirmed solid tumors compared with age- and sex-matched cancer-free (healthy) volunteers. The study is conducted in three parts: Phase 1 validates the assay in 250 patients with cancer; Sub-study 2a compares 1,500 patients with cancer against 1,500 matched cancer-free volunteers; and Sub-study 2b uses serial blood and urine sampling in 300 patients with early-stage disease to assess detection of disease relapse during follow-up, in parallel with standard imaging. The study also estimates positive and negative predictive values (PPV/NPV) and projects the budget impact and cost-effectiveness of Methylscape as a multi-cancer early detection (MCED) tool in an upper-middle-income Latin American setting.

Non-inferiority Study Comparing Salvage Pelvic Radiotherapy in 25 Fractions (62.5 Gy/25) Versus 20 Fractions (52.5 Gy/20) for Recurrent Prostate Cancer After Surgery.

Study Overview This research compares two types of post-operative salvage radiotherapy (SRT) for men with prostate cancer who have had surgery but show signs of recurrence (detectable PSA). The goal is to see if a shorter treatment schedule is as safe and effective as the standard schedule. Why is this study important? After prostate surgery, cancer can return in up to 70-80% of high-risk patients. Radiotherapy helps control this, but the best way to deliver it-especially the number of sessions and whether to treat the pelvic area-is still being studied. Shorter treatments could mean less time in therapy and better quality of life, if such treatments are proven safe. What is being compared? Standard treatment (Arm A): 25 sessions (about 5 weeks) Prostate bed: 62.5 Gy Pelvis: 45 Gy Shorter treatment (Arm B): 20 sessions (about 4 weeks) Prostate bed: 52.5 Gy Pelvis: 43 Gy Both groups may also receive hormone therapy (ADT) for 6-24 months. Main Goal To check if the shorter treatment causes no more side effects (urinary or bowel problems) than the standard treatment, while keeping cancer control similar. Other Things to be Measured Cancer control (PSA levels, spread of disease) Survival Quality of life (urinary, bowel, sexual health questionnaires) Who can join? Men who: Had prostate surgery Have a detectable PSA (≥0.2 ng/mL) No distant metastasis Are in good general health (ECOG 0-2) How long will the study last? About 12 years total: 2 years to enroll patients 10 years of follow-up

Accelerated Partial Breast Irradiation With IMRT in Early Breast Cancer

This study is to evaluate the efficacy and toxicity of accelerated partial breast irradiation (ABPI) with intensity modulated radiation therapy (IMRT) in low-risk breast cancer treat with breast-conserving surgery.

Cadonilimab With Chemoradiation for Recurrent and Oligometastatic Endometrial Carcinoma

The goal of this clinical trial is to evaluate the efficacy and safety of cadonilimab in combination with paclitaxel, cisplatin, and radiation therapy for the treatment of locally recurrent and oligometastatic endometrial carcinoma. The main questions it aims to answer are: 1. Does the combination therapy improve the overall response rate (ORR), progression-free survival (PFS), disease control rate (DCR), overall survival (OS), and safety in participants? 2. What are the predictive biomarkers of treatment efficacy, and how can this information better guide the use of immune-oncology drugs in combination therapy? Participants will: * Receive cadonilimab, paclitaxel, cisplatin, and radiation therapy according to a specified protocol. * Visit the clinic for regular checkups and tests throughout the treatment period. * Be monitored for and have records kept of ORR, PFS, DCR, OS, and safety. * Provide hematologic and tissue samples to explore biomarkers. This study will help determine if this combination therapy can become a new standard of care for patients with locally recurrent and oligometastatic endometrial carcinoma, as well as identify biomarkers to better guide treatment strategies.

Multicenter Clinical Trial on the Effectiveness and Safety of Instillation of BCG and Alternative BCG Protocols for Intermediate and High-risk Non-muscle Invasive Bladder Cancer

Previous studies have reported the efficacy of Bacillus Calmette-Guérin (BCG) combined with other drugs for the treatment of bladder cancer. However, research on the combination of tislelizumab and BCG for bladder cancer treatment has largely been retrospective. Currently, ongoing clinical trials have not discussed the effectiveness of PD-1/PD-L1 inhibitors combined with BCG instillation in reducing postoperative recurrence in intermediate-risk NMIBC. Therefore, this study aims to explore the clinical efficacy and safety of tislelizumab combined with BCG in the treatment of intermediate and high-risk NMIBC. For this purpose, investigators have established strict screening criteria to include eligible patients in the study and have recruited suitable patients from multiple medical centers.Investigators have also developed a meticulous implementation process and follow-up considerations, hoping to better verify the clinical efficacy and safety of the combined use of these two drugs.
