Active clinical trials for "Neoplasms"

Assessment of the mutational profile of the residual clone and the distribution of lymphocyte subpopulations at 3 years of treatment with ibrutinib This project has an epidemiological part: to establish the percentage of patients, in a real-life situation, still undergoing treatment 3 years after its initiation, as well as a biological part: to determine the evolution of the clone and the prevalence of BTK mutations and PLCg2 in the absence of clinical or biological criteria for scalability.

Since the previous decade, the authors introduced the R1 vascular (R1vasc) resection for the treatment of hepatocellular carcinoma (HCC), and colorectal liver metastases (Torzilli et al. J Am Coll Surg 2005; Viganò et al. Ann Surg Oncol 2016; Torzilli et al. Surgery 2017). However, oncological reliability of tumor exposure in surgery for HCC remains controversial since it has never been validated. The aim of the study is to determine the oncological adequacy of R1vasc hepatectomy in patients with HCC.

The aim of this study is intending to provide the optimal procedures of lymph node sorting for pathological examination after curative surgery for gastric cancer, which can discriminate the differences of the status of lymph node metastasis, pTNM classification and prognostic outcome of gastric cancer patients.

Purpose: The "Total Mesorectal Excision" (TME) is the standard surgical technique for the treatment of rectal cancer. Up to 50% of sexual dysfunction is described after TME and up to 30% of urinary dysfunction. The main objective of the study is to compare pre- and post-TME sexual dysfunction according to the approach of the inferior mesenteric vessels, directly on the IMA or from the inferior mesenteric vein (IMV) to the IMA. Methods: Multicenter, prospective, controlled and randomized study of patients with rectal adenocarcinoma with neoadjuvant chemoradiotherapy, who will be randomized into two groups depending on the approach of the inferior mesenteric vessels. The main variable is pre and postoperative sexual dysfunction. The sample to be included will be 90 patients, 45 per group.

This trial studies how well radial-probe endobronchial ultrasound works in detecting the complete or partial collapse of the lung in patients undergoing peripheral bronchoscopy. Diagnostic procedures, such as radial-probe endobronchial ultrasound and bronchoscopy, use a thin, tube-like instrument inserted through the nose or mouth to view and take pictures of the inside of the trachea, air passages, and lungs.

Renal functional reserve may be better in patients with clinical T1 renal cell carcinoma(RCC) undergoing laparoscopic partial nephrectomy with precise segmental renal artery clamping than those with complete renal arterial clamping.

Background: Gastric cancer is a leading cause of cancer deaths around the world. This disease is a serious problem in places like East Asia, Central and South America, and Eastern Europe. Researchers want to study the causes of gastric cancer and its precursors. They want to reduce the number of people with stomach cancer. Objectives: To learn more about bacteria factors and other causes of gastric cancer. To study potential markers associated with precancerous gastric lesions (intestinal metaplasia). Eligibility: Adults ages 40-70 years at certain hospitals in Chile who: Are going to have upper gastrointestinal endoscopies OR have stomach cancer and need surgery Design: Participants will give gastric tissue samples. Some participants will donate a portion of the stomach tissue that is removed as part of their clinical care. Participants will give access to reports of their stomach exam. They will allow researchers to photograph the microscope slides of their tissue samples. Participants will answer questions. The topics of the questions include: Age, height, weight Education Habits including tobacco and alcohol Personal and family history of disease Reproductive history Diet Some participants will give blood, urine, saliva, and stool samples. Study staff will collect the blood. They will tell the participants how to collect the other samples themselves.

Gastric cancer associated peritoneal carcinomatosis has a poor prognosis with a median survival of less than one year. Systemic chemotherapy including targeted agents has not been found to significantly increase the survival in Gastric cancer associated peritoneal carcinomatosis. Since recurrent gastric cancer remains confined to the abdominal cavity in many patients, regional therapies like aggressive cytoreductive surgery and hyperthermic intraperitoneal chemotherapy have been investigated for Gastric cancer associated peritoneal carcinomatosis. Hyperthermic intraperitoneal chemotherapy has been used for three indications in Gastric Cancer- as an adjuvant therapy after a curative surgery, hyperthermic intraperitoneal chemotherapy has been shown to improve survival and reduce peritoneal recurrences in many randomised trials in Asian countries; as a definitive treatment in established PC, hyperthermic intraperitoneal chemotherapy along with cytoreductive surgery is the only therapeutic modality that has resulted in long-term survival in select groups of patients. While the results of randomised trials of adjuvant hyperthermic intraperitoneal chemotherapy from western centres are awaited, the role of hyperthermic intraperitoneal chemotherapy in the treatment of Gastric cancer associated peritoneal carcinomatosis is still evolving and needs larger studies before it is accepted as a standard of care.

Objectives Validate the OncAlert® RAPID Test by demonstrating that NPV > (1 -prevalence). Evaluate the independent and associated contribution of readily available clinical variables including age, race, gender, HPV status, socioeconomic level, tobacco, and alcohol use with the biopsy and test results. Evaluate OncAlert® RAPID Test results in patients without immediate biopsy, both at baseline and scheduled follow-up visit (approximately 1-3 months±14 days), to assess impact on outcome. Planned Number of Subjects A total enrollment of up to 1000 individuals is projected with 600 as the minimum accrued. Patients in the primary cohort (1a and 1b) will be followed until pathology of clinically directed incisional / diagnostic biopsy pathology report is received. Up to 200 'non-biopsy subjects' will be followed during a 1-3 month ±14 days clinic visit. Patient Population Cohorts 1a and 1b: Subjects with a clinical suspicion of oral potentially malignant disorders, oral or oropharyngeal cancer, or both based in part on clinical examination, symptoms, clinical history, suspicious lesion(s) in mouth without history of a prior positive biopsy. Even if the suspicion is low for cancer or precancer, the patient is eligible if a biopsy is performed, in part, to rule this out. For example, if a subject has findings on imaging, or worrisome localizing symptoms in the oral cavity or oropharynx, they would be eligible. In addition, subjects with papillomas or other findings where there is a low level of concern, but cancer is still in the differential, are also eligible. Cohort 1a: oral cavity Cohort 1b: oropharynx Cohort 2: Subjects are enrolled with a clinical suspicion of oral potentially malignant disorders, oral or oropharyngeal cancer, or both based in part on clinical examination, symptoms, clinical history, suspicious lesion(s) in mouth without history of a prior positive biopsy; however, based on clinical impression and or patient related issues no immediate biopsy is obtained. Screen Fail Rate: A 20% Screen Fail Rate is anticipated. Investigational Product Name: OncAlert Oral Cancer RAPID Test (OncAlert RAPID) Methodology Overview Prospectively collect 5cc of normal saline after a combination of swish, gargle and spit into the provided collection specimen cup. Specimens will be collected at baseline (time of biopsy) as per standard practice at each site. The OncAlert RAPID Test cassette is inserted into the specimen cup and read directly from the cassette in 10 minutes. In addition, comprehensive clinical - pathology and patient demographic features including age, gender, race, ethnicity, and all pathology biopsy results will be collected. Any pertinent additional clinical data including HPV status, socioeconomic status, smoking, drinking history, and pertinent features related to oral health will be obtained. A central pathology review for all biopsy results will be performed and incorporated into the final analyses.

This study evaluates the biomarkers CA125 and HE4 and the algorithms RMI and ROMA on a normal population in the western region of Sweden. The aim is to improve diagnosis of ovarian cancer. If the investigators observe a clear improvement in the early diagnosis of EOC, the investigators aim to implement the best strategy for all patients with suspected pelvic tumor mass in the western region of Sweden.
