Station-Specific Lymph Node Metastasis After Neoadjuvant Chemoimmunotherapy for Middle Thoracic Esophageal Squamous Cell Carcinoma

Neoadjuvant chemoimmunotherapy (NCIT) is increasingly used for locally advanced esophageal squamous cell carcinoma (ESCC). However, the station-specific distribution of residual lymph node metastasis after NCIT remains incompletely characterized, and whether a pathologic complete response of the primary tumor implies nodal clearance is unclear. This single-center retrospective cohort study included consecutive patients with middle thoracic ESCC who underwent esophagectomy with lymphadenectomy (at least 15 nodes retrieved) between June 2012 and June 2025. Station-specific lymph node metastasis rates were analyzed in the NCIT group (n = 272) according to residual pathologic T category (ypT), and in the upfront surgery group (n = 445) according to pathologic T category (pT). The two groups followed different clinical pathways and were not randomized; between-group comparisons are descriptive only and no causal inference is intended. The study aims to provide an anatomic basis for surgical planning and postoperative risk stratification in middle thoracic ESCC.

Radiofrequency Ablation of Lung Tumors

Radiofrequency ablation has achieved impressive results in the treatment of unresectable primary and metastatic liver cancer. Animal studies have demonstrated that radiofrequency can fully ablate lung tumors in animal models. We set up a prospective study to evaluate the local efficacy of radiofrequency ablation of lung neoplasms. The aim of the study is to prospectively evaluate local efficacy with a minimal follow-up of one year, tolerance, lung disease-free survival and survival after radiofrequency ablation of lung tumors (primary lung cancer or lung metastases).

Targeted Radiotherapy in Androgen-suppressed Prostate Cancer Patients.

This multi-center, phase II trial will be conducted in men with castration resistant prostate cancer. The aim of the TRAP trial is to test whether a new precise radiotherapy technique called stereotactic body radiotherapy (SBRT) can slow down the growth of metastatic prostate cancer. If SBRT is effective it will represent a new treatment option in these patients, providing more prolonged control without having to resort to chemotherapy and its potentially unpleasant side effects. In this trial, the investigators will identify men who, despite being on next generation androgen deprivation treatment (Abiraterone or Enzalutamide) have developed one or two new sites of worsening (growing) disease but the rest of their cancer is still responding to hormonal therapy. If it is the case that SBRT can successfully treat the cancer which is resistant to current treatment then the investigators hope they will be able to better control the spread of cancer in these patients for longer. The investigators also hope that they will be able to use the tell-tale products (gene markers) that are released into the bloodstream in these patients, or identify characteristics on novel imaging such as magnetic resonance imaging (MRI) to help identify patients in the future who will benefit the most.

Surgery Plus Systemic Therapy for Liver Cancer With Extrahepatic Metastases

This study will evaluate whether resection of the primary liver tumor, in addition to standard first-line systemic therapy, improves survival in patients with hepatocellular carcinoma that has spread outside the liver but still has a resectable primary intrahepatic tumor. Participants will be randomly assigned to receive either primary tumor resection followed by protocol-allowed first-line immune-based systemic therapy or systemic therapy alone. The primary outcome is overall survival. Secondary outcomes include progression-free survival, objective response rate, disease control rate, immune-related adverse events, postoperative complications, and quality of life.

Resection of the Primary Tumor vs. Systemic Treatment Alone for Patients With Small Intestinal Neuroendocrine Tumors and Unresectable Metastases: a Europe-wide Study

When possible, surgery to completely remove small intestinal neuroendocrine tumors (siNETs) is always recommended. However, in cases where the tumor has spread and cannot be cured completely, it is unclear whether a surgical removal of the primary tumor only is reasonable. In this situation, current guidelines from the European Neuroendocrine Tumor Society (ENETS) recommend surgery only for patients who have symptoms like intestinal blockage or bleeding, or are at risk of such complications. For patients without symptoms, it is still unclear whether removing the main tumor improves overall outcomes and prevents future problems. Studies evaluating this type of surgery on survival show conflicting results. These studies often do not separate patients with symptoms from those without, and they overlook other important factors like the amount of cancer in the liver and nearby tissues. Due to these uncertainties, the rarity of siNETs and many factors that can affect outcomes, like age, overall health, or other current treatments, conducting a high-quality study to answer this question is challenging. To address this, the present Europe-wide study is being planned. This study aims to determine if resecting the main tumor improves the 10-year overall survival and reduces risks like intestinal blockages or blood flow issues compared to no surgery in patients without symptoms. The study will also assess other outcomes, such as how long patients stay free from disease progression, the risks of surgery, and prognostic factors for long-term survival. This international collaboration among neuroendocrine tumor referral centers will provide robust evidence to guide clinical practice and update treatment guidelines for siNETs.

A Study of Gefitinib, Trametinib, Disulfiram, and Sunitinib in Addition to Standard Chemotherapy in People With Osteosarcoma

The researchers are doing this study to find out whether adding gefitinib, trametinib, disulfiram, and sunitinib to standard chemotherapy is a more effective treatment approach for people with osteosarcoma than standard chemotherapy on its own. The researchers will also look at the safety of adding these drugs to standard chemotherapy. The researchers will also use the additional research biopsies from Cohort 1 participants to learn more about how osteosarcoma survives during chemotherapy.
