Active clinical trials for "Neoplasms"

We are going to establish "organoid" models from pancreatic cancer biopsies achieved via EUS-FNA. Then the sensitivity of the selected FDA-approved anti-cancer drugs will be tested in these organoids.

Extended pelvic lymph node dissection in bladder carcinoma provides staging and, in selected patients, a survival benefit. Recent studies showed the therapeutic benefit of retroperitoneal lymph node dissection (RPLND) in advanced stage of upper tract urothelial carcinoma (UTUC). Also laparoscopic extended RPLND is still a technical challenge in urology, considering the high rate of severe complications and difficulties in manipulation. In Renji Hospital, laparoscopic extended RPLND at time of nephroureterectomy was performed via an extraperitoneal approach, avoiding interference with abdominal organs and achieving better exposure.The aim of the present study was to determine the safety and feasibility of performing an extraperitoneal laparoscopic extended RPLND at the time of radical nephroureterectomy (RNU) for UTUC in a prospectively collected cohort of patients.

Acute colon cancer surgery has a poor 90-day mortality of 21.0% compared with only 3% after elective colorectal cancer surgery in Denmark. The high mortality after acute colon cancer surgery compared with elective surgery emphasizes the importance of identifying factors associated with acute onset and poor short-term survival after acute surgery. Socioeconomic position has previously showed to be a risk factor for acute versus elective onset of colorectal cancer. Furthermore, if patients with low socioeconomic position have higher postoperative mortality this could reflect differences in the treatment of patients according to their socioeconomic position. The aim of the clinical study is: To examine if patients with short education, low income, living alone, or living in rural areas are more likely to undergo acute colorectal cancer surgery than elective surgery compared with patients with longer educations, higher income, living with a partner, or living in urban areas. To examine if there is an association between education, income, cohabitation, or urbanicity and 1-year mortality after acute colorectal cancer surgery.

Hepatocellular carcinoma is one the leading cause of increasing cancer-specific mortality worldwide. Early diagnosis of hepatocellular carcinoma provides opportunity for curative therapeutic approaches and relatively favorable prognosis. Herein, we intended to establish a biosignature for early diagnosis of hepatocellular carcinoma and stratification of risk population for intensive follow-up by implementing biannual follow-up investigation and collecting peripheral blood samples for screening.

The hypothesis of this study are as follows: Prognostic evaluation of patients based on an integrative model provides better assessment of overall survival, and thus improves setting of care goals. In a routine care population, antitumour drugs may have a significant impact on overall survival through their targeted antitumor effect, but also through their toxicity profile and their impact on comorbidities. The optimization of patient support (supportive care, drug tolerance monitoring) can have an impact on the prognosis.

Anti-cancer treatments have been thought to be closely related to their unique genetic alterations. In the past few years, the investigator have used cDNA microarray to delineate the transcriptome profiles of differentially-expressed genes between OSCC tumors and normal epithelium. By supervised hierarachical clustering analysis, the investigator further analyzed and validated the differentially-expressed genes for OSCC tumors. In the investigators' previous research, the investigators have used this strategy to analyze the potential tissue proteins associated with OSCC tumors, indicating the feasibility of this strategy. However, gene detection is a great limitation and challenge in CTCs researches owing to the small number of isolated cells by traditional methods. Fortunately, by means of the investigators' developing high-purity CTCs isolation techniques, some preliminary data implied that isolated CTCs by this method could achieve the criteria of Whole-genome analysis (WGA), which brings the investigators' passion for further investigation.

To choose a subgroup who could clearly benefit from Nivolumab, we are proposing a prospective observational study. Whole-genome study (WGS) analysis will be performed on archived cancer tissues from patients who were (1) cisplatin-refractory and subsequently (2) received Nivolumab (at least 4 doses) and (3) had completed imaging response evaluation at 3-4 month after Nivolumab. The estimated sample size was designed to be 80, including 20 responders and 60 non-responders (1:3 design) after Nivolumab alone at a dosage of 2-3mg/kg every 2 weeks (+/- 7 days could be allowed), given the minimal requirement of statistical significance. The specific bio-signature(s) found in this prospective observational study could possibly greatly contribute to precision immuno-oncology medicine, especially Nivolumab.

Evaluation of the role of serum midkine in differentiating malignant from benign thyroid nodule studying the level of serum midkine in relation to different thyroid cancer stages

Locally advanced head and neck squamous cell carcinoma (LAHNSCC) is a heterogeneous disease, associated with a poor prognosis and no improvement in overall survival for years. Furthermore, treatments (surgery, radiotherapy, chemotherapy) are frequently associated with acute and late toxicities. Beside p16/HPV + tumors, only TNM classification can help estimating the prognosis of the patients. A better evaluation of the prognosis and of the risk of metastatic spread would help defining the best treatment. Circulating tumor DNA (ctDNA) has been reported as both a prognostic factor and a non-invasive way to assess tumor relapse in several cancer types. Few data are available in HNSCC, and no data among p16/HPV- cancers. Indeed, ctDNA assessment is usually based on tumor mutation monitoring. But if recurrent mutations are frequent in several cancers types (PIK3CA, KRAS, ESR1, TERT…), there is no recurrent mutation observed in HNSCC. Thus ctDNA assessment in LAHNSCC must be performed after the identification of a tumor specific mutation for each patient. In that context, the aim of this study is to perform a molecular analysis of primary LAHNSCC, and to look for the amount of ctDNA before surgery, after surgery, and during 18 months of follow up.
