Active clinical trials for "Neoplasms"

Renal cell carcinoma (RCC) is the most frequently occurring primary renal neoplasm. There are several histological variants of RCC that are associated with variable prognostic outcomes. Epithelial-mesenchymal transition (EMT) is a phenomenon in which the epithelial cells acquire some mesenchymal criteria as enhanced invasive potential. There are several cell surface molecules that are implicated in EMT. Moesin is one of these molecules that is involved in EMT, which is associated with enhanced invasive potential and poor prognosis. Targeting Moesin by novel therapeutic agents may prevent EMT and improve prognosis of patients with RCC.

Tumor deposits (TD), nodules in the peritumoral adipose tissue with no architectural residue of lymph node, which is a definition often being confusing to the extranodal extension (ENE), have been described in several malignancies and linked to a worse prognosis. In gastric cancer and colon cancer, TD and ENE should be distinguished and collected separately in 8th AJCC manual. However, in thyroid cancer, TD as a collection variable was absence in both the 8th AJCC manual and the 2015 ATA guideline. This is a study that revealed the presence of TD by reviewing a large number of papillary thyroid carcinoma (PTC) specimens and explored its prognostic value by constructing a nomogram to accurately predict disease-free survival in PTC patients.

Aim: The current study targets linking serum and salivary dipeptidyl peptidase-4 with oral squamous cell carcinoma and comparing it with potentially malignant lesions and control to validate dipeptidyl peptidase-4 as a diagnostic marker for early detection of oral cancer and to reveal its possible role in carcinogenesis. Methodology: A total of 45 patients were recruited and subdivided into 2 groups: Group I: 15 patients having oral squamous cell carcinoma. Group II: 15 patients with potentially malignant lesions (leukoplakia and oral lichen planus) compared to 15 systemically healthy participants having no oral mucosal lesions acting as a control group (Group III). Serum and whole unstimulated salivary samples were collected from all participants to evaluate dipeptidyl peptidase level in different groups using enzyme linked immune-sorbent assay (ELISA) kit. ROC analysis was done to reveal area under the curve, sensitivity, specificity and diagnostic accuracy of DPP-4 among different groups.

Breath analysis examining specific patterns of volatile organic compounds (VOCs) has been demonstrated to be able to discriminate lung cancer (LC) patients from healthy controls (HC). However, the existing technology uses complex, expensive, and low throughput analytical platforms to give an offline response, thus preventing its applicability for mass screening. The reliability of a new portable device to enable rapid, on-site LC diagnosis is tested.

This is a multicenter, retrospective, observational study. Textbook outcome is a composite outcome measure for surgical quality assessment. The aim of this study was to assess textbook outcome following laparoscopic pancreaticoduodenectomy in China, identify factors independently associated with achieving textbook outcome and analyze hospital variations regarding the textbook outcome after case-mix adjustment.

To determine whether the presence of circulating/disseminated tumour cells (CTCs/DTCs) in the blood and bone marrow of the resectable lung cancer (NSCLC) patients is a negative prognostic factor, and to find correlations with other clinical/pathological disease characteristics.

Paraneoplastic neurological syndromes (PNS) are rare complications of cancer occurring in 0.01% of cases. Their clinical, biological and radiological presentation is heterogeneous and may constitute a diagnostic challenge. Anti-Ma2 PNS are rare diseases with a guarded prognosis. They are most often associated with a seminoma-like testicular tumor but can also be associated with lung cancer. Classically, they present as limbic, diencephalic and/or brainstem encephalitis. Anti-Ma2 antibodies target intracellular receptors and are characteristic of a particular form of encephalitis. Atypical manifestations including narcolepsy-cataplexy, weight gain, sexual dysfunction and motor neuron syndrome have been described and explain the difficulty in diagnosing anti-Ma2 associated PNS. It seems interesting to better characterize the phenotypes of Ma2 patients in order to optimize the diagnosis and follow-up.

To determine whether older patients who underwent esophagectomy had better outcome survival than those who were non-surgically treated.

This was an observational study utilizing electronic health record (EHR)-derived data collected retrospectively during routine care of real-world patients with advanced melanoma from NOBLE (Novartis Braf+ meLanoma patients ObsErvational) dataset.

Orbital solitary fibrous tumors are rare tumors with an intermediate potential of malignancy. Orbital solitary fibrous tumors' prognostic criteria are still poorly understood. Some patients with orbital solitary fibrous tumors have been treated at the Adolphe de Rothschild Foundation Hospital. This cohort will be studied to describe the recurrence rate and to identify predictive factors of recurrence or metastasis.
