Simplified Exercise-based Risk Assessment in Lung Cancer

Physiological evaluation is part of the preoperative risk estimation in patients with lung cancer, and it aids in the choice of treatment. Ventilatory efficiency during exercise has emerged as a strong predictor of major postoperative complications, so far determined during a maximal cardiopulmonary exercise test. However, this test is limited by its availability and high cost, due to the requirement of high-technological equipment and advanced expertise. The current project aims to evaluate a simplified and accessible method for risk evaluation before decision on treatment in lung cancer. It builds on recent advances in technology and knowledge and combines a simple, low-intensity cycling test with measurement of ventilatory efficiency (end-tidal carbon dioxide pressure) with a handheld monitor. In a prospective, multi-center design the investigators will include patients evaluated for suspected lung cancer. The main objective is to establish threshold values for end-tidal carbon dioxide associated with low respectively high risk of major complications in patients undergoing surgery. In addition, the study aims to determine if end-tidal carbon dioxide can predict severe side-effects during neoadjuvant or curatively aiming systemic therapy. The project is closely linked to clinical practice, and the results can be easily implemented due to the simple and cost-efficient methodology. the suggested simplified approach would also allow access to physiological evaluation where more advanced methods are unavailable.

Tumor Margin Skin Tattooing Before Neo-adjuvant Chemotherapy in Patients With Breast Cancer

Study Description This prospective cohort study evaluates the feasibility and effectiveness of pre-neoadjuvant tumor localization using skin tattooing, with or without radiopaque clips, in patients with biopsy-proven T2-T3 breast cancer and axillary lymph node metastasis. Eligible patients will undergo tumor localization in the supine position with the ipsilateral arm abducted to 90°. Palpable tumor margins will be marked with sterile tattoo ink, and deep or mobile tumors will receive additional localization with ultrasonography-guided radiopaque clips. Following localization, patients will receive standard neoadjuvant chemotherapy. Tumor response will be monitored clinically and radiologically. Post-therapy, the tattoo markings and/or clips will guide breast-conserving surgery. Primary outcomes include feasibility of breast conservation, achievement of negative margins (R0 resection), and avoidance of mastectomy, while intraoperative technical challenges will also be documented.

Neoadjuvant Immunochemotherapy and Postoperative Adjuvant Immunotherapy for Head and Neck Squamous Cell Carcinoma Invading the Skull Base

This prospective, single-arm, Phase II clinical trial aims to evaluate the efficacy and safety of tislelizumab combined with chemotherapy as neoadjuvant therapy and postoperative adjuvant immunotherapy in patients with skull base-invading head and neck squamous cell carcinoma. The primary objectives are to address the following questions: * What are the objective response rate and pathological response of tislelizumab combined with chemotherapy as neoadjuvant therapy in patients with skull base-invading head and neck squamous cell carcinoma? * Can neoadjuvant therapy convert unresectable skull base-invading head and neck squamous cell carcinoma into a resectable condition? * Can adjuvant immunotherapy after neoadjuvant therapy prolong patients' recurrence-free survival and overall survival? The researchers will administer neoadjuvant therapy (tislelizumab combined with chemotherapy) and adjuvant immunotherapy to patients with skull base-invading head and neck squamous cell carcinoma and assess the treatment's efficacy and safety. Participants will: * Receive neoadjuvant therapy every 3 weeks (tislelizumab 200mg on Day 1, nab-paclitaxel 260mg/m² on Day 1, cisplatin 75mg/m² on Days 1-3) for 3 cycles. * Undergo surgical treatment within 3 weeks after completing neoadjuvant therapy. * Receive (chemo)radiotherapy 4-6 weeks after surgery. * Receive adjuvant immunotherapy (tislelizumab 200mg) every 3 weeks after (chemo)radiotherapy for 8 cycles.

Adebrelimab Combined With Carboplatin and Albumin-bound Taxanol in the Treatment of Resectable Locally Advanced Oral Squamous Cell Carcinoma Cardiac, Randomized, Phase II Exploratory Study

Neoadjuvant immunochemotherapy can effectively increase the postoperative pathological complete response rate, improve the survival rate of patients, and reduce the risk of recurrence in oral squamous cell carcinoma (OSCC). Programmed death ligand-1 (PD-L1) plays a role in inhibiting the cancer-immune cycle by binding to negative regulatory factors of T cell activation such as PD-1 and B7.1. It has achieved good therapeutic effects in lung cancer, liver cancer and other cancers. Previous studies have shown that three cycles of PD-L1 inhibitors combined with chemotherapy have satisfactory efficacy and safety in locally advanced oral squamous cell carcinoma. However, during the three-cycle treatment process, due to the accumulation of drug toxicity, patients' tolerance to adverse reactions decreases, increasing the risk of serious adverse events and psychological pressure on patients. Based on this, this study aims to explore the efficacy of two cycles of avelumab (PD-L1 inhibitor) combined with chemotherapy in locally advanced oral squamous cell carcinoma, to explore whether it can achieve the same efficacy as three cycles while shortening the treatment time, reduce the risk of serious adverse events, and further verify the efficacy and safety of PD-L1 inhibitors combined with chemotherapy in the treatment of locally advanced oral squamous cell carcinoma. This study uses the postoperative pathological complete response (PCR) rate as the primary outcome indicator, and the objective response rate (ORR), major pathological response (MPR) rate, 2-year disease-free survival (EFS) rate, and 2-year and 5-year overall survival (OS) rate as secondary outcome indicators to evaluate the efficacy and long-term survival impact.

NEoadjuvant Chemotherapy and Immunotherapy for a Selected Group of Inoperable Pleural Mesothelioma Patients (NECIM): a Feasibility Study

The goal of this clinical trial is to evaluate whether a combination of chemotherapy and immunotherapy can make surgery possible in adults with inoperable pleural mesothelioma (a type of cancer affecting the lung lining). The main questions it aims to answer are: Can two cycles of neoadjuvant chemotherapy and dual immunotherapy, followed by surgery, be completed safely and effectively? Does this treatment allow previously inoperable patients to become eligible for surgery and improve survival outcomes? Participants will: Receive two cycles of chemotherapy (cisplatin or carboplatin and pemetrexed) Receive dual immunotherapy (nivolumab and ipilimumab) Undergo evaluation by a multidisciplinary team to determine if surgery is possible If operable, undergo extended pleurectomy/decortication surgery Be followed for one year to assess side effects, quality of life, and survival

Pucotenlimab Combined With Chemotherapy as Perioperative Treatment for Locally Advanced Gastroesophageal Junction Carcinoma

This study is a prospective, multicenter, single-arm clinical trial. The study intends to enroll patients with pathologically or cytologically confirmed resectable locally advanced gastroesophageal junction tumors (cT2N+M0 and cT3-4bNxM0) who have not received prior systemic therapy. After signing the informed consent and being screened to meet the inclusion and exclusion criteria, patients will receive 3 cycles of Pucotenlimab combined with chemotherapy (Nab-Paclitaxel + Tegafur + Carboplatin). Preoperative imaging evaluations will be performed 3 to 6 weeks after the final dose administration to assess the efficacy of neoadjuvant therapy and the feasibility of radical resection. Efficacy evaluation will be performed after radical surgery for locally advanced gastroesophageal junction tumors.
