Pleural Carcinomatosis Tissue Banking
Pleural EffusionMalignantMalignant pleural effusion is a common evolution of various cancers and is associated with poor prognosis and quality of life. About 28% of patients with primary malignancy will develop pleural metastasis. Malignant pleural effusion mostly occurs in lung, breast, ovarian and gastric cancers. Median survival ranges from 3 to 13 months according to primary malignancy. Currently, the therapeutic approach is mainly palliative with videothoracoscopic talc pleurodesis or indwelling pleural catheters insertion eventually associated with systemic chemotherapy if patient's general condition allows. In a early-disseminated tumor cells profile, metastatic cells can accumulate alterations at a distant site and have a different profil from the original tumor cells. Metastatic cells can also accumulate alterations in the course if systemic treatments. Consequently, they may respond differently to drugs. Recently, EGFR mutations and ALK status discordance between primary tumors and pleural metastases have been demonstrated in a significant portion of lung adenocarcinomas. These studies, realized on malignant pleural effusion isolated cells, enabled us to hypothesize a possible intratumoral heterogeneity within pleural metastases, but no study has been carried out on pleural tissue. Our aim is to create a biocollection with tissues from pleural carcinomatosis in order to subsequently allow multiomics and bioinformatics analyzes and to characterize a possible intratumoral heterogeneity in pleural metastasis.

Adrenal Vein Sampling as a Tool to Identify Biomarkers That Aid the Diagnosis of Adrenocortical...
Adrenocortical CarcinomaThe goal of this observational pilot study is to explore whether we can identify biomarkers predictive for the diagnosis of adrenocortical carcinoma in blood. Five participants who are suspected to have adrenocortical carcinoma will undergo an adrenal vein sampling in order to obtain a blood sample from the adrenal vein. This blood sample will be analyzed and compared to blood samples taken from the adrenal vein of 20 control patients, which are patients who do not have adrenocortical carcinoma. The blood samples of the control patients will be drawn during routine medical care.

IMP3 and PCNA Expression in Laryngeal Squamous Cell Carcinoma in Sohag Governorate
Laryngeal Squamous Cell CarcinomaLaryngeal cancer is responsible for 2-5% of all new cancer cases worldwide. Squamous cell carcinoma of the larynx (LSCC) is the most common malignant tumor of the larynx, accounting for 85-90% of all laryngeal malignancies. Despite significant therapeutic developments in recent decades, increases in patients' 5-year survival rates are still minimal , which is likely due to late-stage diagnosis and other complex factors. Therefore, to improve the outcome, timely diagnosis, selection of the most appropriate therapy, and an adequate follow-up approach is needed. The insulin-like growth factor II m-RNA-binding protein 3 (IMP3) is a new biomarker that may be implicated in the carcinogenesis of various malignancies, including head and neck squamous cell carcinoma. IMP3 normally expressed in embryonic tissue but decreases after birth and is no longer detectable in adult tissue With the exception of a few tissues. As a result, IMP3 is expressed only in tumors and not in neighboring normal tissues. Proliferating Cell Nuclear Antigen (PCNA) is a nuclear protein that acts as a cell proliferation marker. In most forms of solid malignancies, such as colorectal cancer and breast cancer, PCNA is closely linked to prognosis and survival. In this study, hoping to improve diagnosis of LSCC and assess prognosis better by using both IMP3 and PCNA biomarkers. As IMP3 may have a role in cell growth and proliferation and PCNA is a marker of cell proliferation; studying the association between both markers in laryngeal carcinoma is recommended.

Epidermoid Cancer Development in Esophageal Achalasia
AchalasiaEpidermoid CarcinomaEsophageal achalasia is a precancerous condition for epidermoid carcinoma; incidence and risk factors for cancer development are not defined. Incidence and risk factors for epidermoid carcinoma development in achalasia patients were investigated.

MRI and Gene Expression in Diagnosing Patients With Ductal Breast Cancer In Situ
Ductal Breast Carcinoma In SituThis clinical trial studies magnetic resonance imaging (MRI) and gene expression in diagnosing patients with abnormal cells in the breast duct that have not spread outside the duct. MRI uses radio waves and a powerful magnet linked to a computer to create detailed pictures of areas inside the body. MRI may help find and diagnose patients with breast cancer. It may also help doctors predict a patient's response to treatment and help plan the best treatment. Genetic studies may help doctors predict the outcome of treatment and the risk for disease recurrence. Performing MRI with genetic studies may help determine the best treatment for patients with breast cancer in situ.

Preclinical Study Towards an Immunotherapy in Adrenocortical Carcinoma
Adrenocortical CarcinomaCushing's SyndromeAdrenocortical carcinoma (ACC) is a rare and heterogeneous malignancy with poor prognosis. Surgical resection of the tumor is the treatment of choice. However, even after complete resection more than 80 % of patients will experience recurrence of disease. Therefore, new treatment options are urgently needed. This pre-clinical study try to lay the foundations for a successful immunotherapy in patients with ACC.

TFE Renal Cell Carcinoma: A Prospective Registry and Translational Research Initiative
Renal Cell CarcinomaThere are limited data regarding the biology and treatment of TFE Renal Cell Carcinoma (TFE RCC). This project provides the infrastructure for acquisition of biological specimens, imaging, and correlative clinical data to facilitate biology studies and characterization of TFE RCC. This registry will collect clinical, demographic, and pathological data, specimens (as available) and imaging from patients with TFE RCC, prospectively. Cases are identified through: Existing clinical and/or cancer registry databases Referrals from clinicians, surgeons, or pathologists Families initiating contact with Registry staff directly

Registry Platform Urologic Cancer
Renal Cell CarcinomaUrothelial CarcinomaThe purpose of the project is to set up a national, prospective, longitudinal, multicenter cohort study with associated satellites, a tumor registry platform, to document uniform data on characteristics, molecular diagnostics, treatment and course of disease, to collect patient-reported outcomes and to establish a decentralized biobank for patients with advanced renal cell carcinoma or advanced urothelial cancer in Germany.

Evaluation of Urinary Exosomes Presence From Clear Cell Renal Cell Carcinoma
Clear Cell Renal Cell CarcinomaClear cell renal cell carcinoma is diagnosed by imaging, sometimes associated with biopsy. This diagnosis is expensive, invasive and sometimes late. The development of a simple biological test for diagnosis is essential. Exosomes are 30 to 150 nm membrane vesicles secreted into the extracellular space by various living cells. These exosomes can be isolated from biological fluids, including urine. The recent study of urinary exosomes is a promising topic for analyzing tumor markers in urine. The investigator's goal is to develop a reliable technique for detecting tumor exosomes in urine in patients with clear cell renal cell carcinoma. The analysis of urinary exosomes could provide a new liquid biopsy tool for the early diagnosis of clear cell renal cell carcinoma.
