Background: Gastrointestinal Stromal Tumors (GISTs) are gastrointestinal mesenchymal tumors that commonly originate from the digestive tract. They are characterized by their morphology and typically show positivity for CD117 (c-kit). The activation mutations of the KIT or PDGFRA genes are the main drivers of GIST development. GISTs are most commonly found in the stomach ...

The CLDN protein family consists of at least 27 transmembrane proteins, which can be classified into two types: classical and non-classical, based on their sequence. CLDN18 belongs to the non-classical type. The protein expressed by CLDN18 undergoes splice modifications, resulting in two subtypes: CLDN18.1 and CLDN18.2. CLDN18.2 is a highly selective marker protein that ...

1. Overall survival (OS) Overall survival was defined as the time from randomization (or start of treatment in single-arm trials) to death from any cause. OS is relatively objective and precisely measurable, and it is the most reliable end point for measuring the clinical benefit of anticancer drugs in randomized controlled clinical trials. Advantages: It is widely used ...

Globally, it ranks as the eighth most common malignant tumor among women and is the most deadly gynecologic malignancy, with the highest mortality rate among the three major gynecologic tumors (ovarian, cervical, and endometrial cancers) [1].

Abstract Ovarian endometrioid (ENOC) is one of the important subtypes of ovarian cancer, accounting for 10-15.8%, which is related to endometriosis and Lynch syndrome. The morphological heterogeneity of ENOC is high, and the prognosis is also different. ENOC and endometrioid carcinoma (EEC) have many similarities in molecular characteristics and histology. The applicatio...

Background RECIST (The Response Evaluation Criteria In Solid Tumors) is a set of definitions for assessing the effectiveness, stability, or ineffectiveness of tumor treatment. This guideline mainly introduces the standardized method of objectively evaluating the changes in tumor size in clinical trials of solid tumors in adults and children. The first tumor response cri...

Background Malignant pleural effusion (MPE), also known as pleural effusion, is a pleural effusion caused by the metastasis of malignant tumors originating in the pleura or other malignant tumors involving the pleura. Almost all malignant tumors can invade the pleura and produce MPE, which is more common in lung cancer, breast cancer, gastrointestinal cancer and other ca...

Neoadjuvant immunotherapy for lung cancer mainly refers to the use of immune checkpoint inhibitors (ICIs) to eliminate the immune suppression of tumor cells on T cells by blocking immune checkpoint molecules such as PD-1/PD-L1/CTLA-4, and thereby reactivating T cells to clear tumor cells [2]. Currently, clinical research on neoadjuvant immunotherapy for Non-small cell lu...

Background Introduction Lung cancer is the most common cancer in the field of tumors, and it is also the malignant tumor with the highest morbidity and mortality in the world. The most common type of lung cancer is non-small cell lung cancer (NSCLC), accounting for 80% to 85% of all lung cancers. Due to its low degree of malignancy, the growth and division of cancer cell...
