Dynamic ctDNA-Guided Adjuvant Therapy in cStage III and IVA Gastric or Gastroesophageal Junction Adenocarcinoma

This is a single-center, prospective, exploratory study evaluating the use of dynamic circulating tumor DNA (ctDNA) monitoring in the postoperative adjuvant treatment setting for patients with stage III or stage IVA gastric or gastroesophageal junction adenocarcinoma. After curative-intent surgery, patients remain at risk of disease recurrence. Postoperative treatment decisions are currently based on clinicopathological factors, which may not fully reflect minimal residual disease. ctDNA is a blood-based biomarker that can detect tumor-derived DNA fragments and may provide additional information on recurrence risk. In this study, ctDNA will be assessed at predefined perioperative and postoperative time points using peripheral blood samples. The primary objective is to evaluate 1-year disease-free survival. Secondary objectives include survival outcomes, safety, and longitudinal changes in ctDNA status. The findings of this exploratory study may inform future research on ctDNA-guided postoperative management in gastric cancer.

Evaluating the Use of a Medication 'Switch' vs Guideline-directed Interventions for Relieving Side Effects of Aromatase Inhibitors Among Breast Cancer Patients

Researchers have learned that about 50% of women do not finish the standard 5-year breast cancer treatment with an aromatase inhibitor. An aromatase inhibitor is hormone therapy that lowers the chance of breast cancer coming back (recurring) after surgery by blocking an enzyme in fat tissue called aromatase; aromatase changes other hormones in the body to estrogen. Women who do not complete the standard 5-year treatment are at higher risk of their cancer coming back. The goal of this research is to prevent breast cancer from coming back after surgery by helping women to stay on treatment with aromatase inhibitors. Researchers believe the best path to help women to stay on treatment is to create a better way to manage (control) side effects.

A Study to Assess the Efficacy and Safety of Firmonertinib Versus Placebo for Adjuvant Treatment in Participants With Stage IB - IIIB NSCLC With Uncommon Epidermal Growth Factor Receptor (EGFR) Mutations, Following Complete Surgical Resection With or Without Adjuvant Chemotherapy（FIRMOST）

This is a Phase 3, global, double-blind, randomized, controlled multicenter clinical study to assess the efficacy and safety of adjuvant treatment with firmonertinib versus placebo in participants with Stage IB-IIIB NSCLC with uncommon EGFR mutations (exon 20 insertions, PACC and classical-like mutations) after complete surgical resection with or without adjuvant chemotherapy. About 338 eligible participants will be enrolled and randomized in a 1:1 ratio to receive either firmonertinib 240 mg QD or placebo QD in 21-day treatment cycles. Before randomization, the participant must have undergone complete surgical resection (R0 resection), must have sufficiently recovered from surgery, and must have completed adjuvant chemotherapy (if applicable). The participants will receive firmonertinib or placebo as adjuvant treatment until unacceptable toxicity, withdrawal of informed consent, disease recurrence, initiation of new antitumor treatment, completion of treatment, or other end of treatment reason is met.

Iparomlimab and Tuvonralimab Injection (QL1706) Combined With Bevacizumab for Postoperative Adjuvant Therapy in Hepatocellular Carcinoma (HCC) With High Risk of Recurrence

Evaluation of the efficacy and safety of Iparomlimab and Tuvonralimab Injection (QL1706) in combination with bevacizumab for postoperative adjuvant treatment of HCC with high-risk recurrence risk

One-year Recurrence-free Survival of Melanoma Patients Eligible for a Sentinel Lymph Node Biopsy

Melanoma is one of the most aggressive solid cancers, although mortality can be reduced with early treatment. Immunotherapy has transformed the prognosis of this pathology. The sentinel lymph node technique is used to classify the severity of melanoma. It is proposed for melanomas with a Breslow thickness of 0.8 mm to 1 mm, and recommended for melanomas greater than 1 mm or with ulceration, whatever the Breslow index. This technique is particularly useful for assessing pathology by detecting the presence of lymph node metastases. Patients with lymph node involvement (micro or macro) are eligible for adjuvant treatment. The new recommendations suggest adjuvant immunotherapy for stages IIB and IIC (without lymph node involvement assessed by the sentinel lymph node technique). This procedure is widely used at the CHRU de NANCY. The aim of this study is to demonstrate the value of the sentinel lymph node in assessing the risk of melanoma recurrence at one year (or more).

The Efficacy and Safety of Ensartinib As Adjuvant Therapy in Stage I ALK-positive NSCLC Patients with High Risk Factors

This study is designed to evaluate the efficacy and safety of a 2-year adjuvant treatment with Ensartinib in stage I ALK-positive non-small cell lung cancer (NSCLC) patients with high-risk factors. The study population includes patients with ALK-positive NSCLC who have undergone R0 resection and have not received any postoperative treatment, with a TNM stage of I and high-risk factors for recurrence.

Adjuvant Treatment of Digestive Tract Tumors

To evaluate the 3-year Disease-free survival rate(DFSR) of patients with locally advanced gastric cancer and colorectal cancer treated with anlotinib combined with adjuvant chemotherapy.
