Despite advances in breast cancer prevention, diagnosis, and therapy, 5-10% of patients with breast cancer have metastatic disease at initial presentation, and approximately 30% of patients with breast cancer develop metastatic disease during the course of disease. Metastatic cascade is a multistep

In terms of frequency, colorectal cancer is the third most common cancer diagnosed in men and the second in women. Screening for colon and rectal cancer is based on the search for blood in the stool. The detection of occult bleeding is an indication for colonoscopy to find the origin of this

The most serious aspect of neoplastic disease is the spread of cancer cells to secondary sites, often distant from the primary site of growth. Bone is a breeding ground for many types of cancer, especially those derived from breast, prostate and lung. Despite the enormous progress in diagnosis and

Rheumatoid arthritis (RA) is a chronic, progressive, autoimmune disease of synovial joints. Disease progression is characterized by periods of high disease activity involving both, a systemic immune response and tissue-specific inflammatory events that may lead to joint and bone destruction and

Currently, malignant tumors are the leading cause of death. Surgery, chemotherapy, radiation therapy, and targeted therapy have become the four foundations of cancer treatment for many years. With the development of science and technology, immunotherapy has become the "fifth pillar" of cancer

Prostatic specific antigen (PSA) circulates mostly in complex with protease inhibitors, but 10-30% circulates as inactive free-PSA (FPSA). In patients with prostate cancer (PCa), pretreatment FPSA is lower and used to risk-stratify patients for biopsy. However, posttreatment FPSA ratio (FPSAR) is

Background: Osteosarcoma (OS) is the most common type of primary malignant bone tumor in children and adolescents. The overall survival rate is dramatically reduced by the development of metastases, often pulmonary. Solid malignant tumors, such as OS, often develop a hypoxic microenvironment, which

Breast cancer is the most common female malignancy worldwide. Despite advances in cancer diagnosis and treatment in recent years, traditional treatments (radiotherapy, chemotherapy, and hormone therapy) are always limited by the resistance of some tumor cells, thus forcing researchers to continue to

Colorectal cancer (CRC) is a major public health problem in France and worldwide. CRC is the third most common cancer in incidence and mortality in France. The vast majority of these cancers are adenocarcinomas that arise sporadically and develop from precursor lesions: adenoma. All CRC with the

Several studies have been performed to understand the cellular mechanisms involved in the development of VTE in cancer patients. The pathogenesis of a thrombotic state is linked to the presence of a tumor and is associated with the development of a hypercoagulant state, namely coagulopathy, which

PRIMARY OBJECTIVES: I. To compare the rates of achieving prostate-specific antigen (PSA) remission at month 7 with LHRH analogue therapy and enzalutamide (Arm A) with that achieved with LHRH analogue and bicalutamide (Arm B) in metastatic hormone sensitive prostate cancer. SECONDARY OBJECTIVES: I.

INTRODUCTION Squamous cell carcinoma antigen (SCCA) is a protein with a strong homology to the family of protease inhibitors known as serpins. SCCAs are cytoplasmic proteins: they are found in normal squamous epithelia, and in elevated levels in the serum of patients with squamous cell carcinomas,

For ovarian cancer, colorectal and gastric cancers presenting with peritoneal metastases, complete tumor removal at surgery is the most important independent prognostic factor. Consequently, accurate detection of tumors often compromising resectability, like extra-abdominal metastases, liver

Due to their easy accessibility, pleural effusions and ascites are two important clinical sources of metastatic cancer cells, which upon isolation, permit comparative studies between the biology nature of primary tumor and metastatic ones. In this study, we will try to isolate cancer cells from

Summary We will perform a 2 year double blind, placebo controlled trial of doxycycline in 40 patients with LAM. The main endpoints will be change in FEV1, other measures of efficacy, safety and dose required to suppress MMP activity. After clinical evaluation, lung function, shuttle walk, QoL
