NCT ID: NCT04906343 Recruiting - Colonic Neoplasms Clinical Trials

Endoscopic Surveillance in Serrated Polyposis Syndrome and Low-risk of Advanced Neoplasia

Start date: June 5, 2021
Phase: N/A
Study type: Interventional

The aim of the study is to determine if Serrated Poliposis Syndrome (SPS) patients with SPS criteria 2, with clearing phase achieved and without any advanced lesion or less than 5 relevant lesions at last colonoscopy have the same advanced neoplasia incidence in the surveillance colonoscopy at 2 or 3 years. Patients selected for the study will be randomised in two groups for the surveillance: group 1, surveillance with colonoscopy in two years; group 2, surveillance with colonoscopy in three years. Randomization will be done at the database program (RedCAP). All colonoscopies will be performed with high definition (HD) system and it will be the choice of the endoscopist whether to use chromoendoscopy with indigo carmine o virtual chromoendoscopy. Protocol bowel preparation will be recommended by each centre. Sedation will be prescribed and decided by the endoscopist during the examination. Data from all the resected and visualized lesions during the colonoscopy will be collected on the database. A pathologist familiarized with serrated lesions will be in charge of the sample analysis. Serrated lesions will be classified attending de WHO criteria for serrated lesions. The investigators define "advanced adenoma" as adenomas ≥10 mm with villous histology and/or with high grade of dysplasia (HGD). The investigators define "advanced SL" as any SL ≥10mm and any SL with dysplasia. The investigators also define "advanced neoplasia" as any colorectal cancer (CRC), any advanced adenoma or advanced Serrated Lesions (SL). Quality of bowel cleansing will be graded by each endoscopist following the Boston Bowel Preparation Scale. This scale evaluates each segment (ascending colon, transverse colon and descending colon) of the following form: 0 = segment of colon whose mucosa cannot be seen due to the existence of solid stools that cannot be eliminated; 1 = mucosa portion of a colonic segment that can be seen, but other areas of the colonic segment are not seen, either due to the presence of dirt, feces or opaque liquid; 2 = existence of small amount of dirt, small fragments of stool and / or opaque liquid, but the mucosa of the colonic segment can be seen well; 3 = all the mucosa of the colonic segment can be seen well without residual dirt, small traces of stool or opaque liquid. Patients with inadequate preparation (when in any segment the score is 0 or 1, or the total score is less than 6) will be excluded from the study. During colonoscopy all complications as post-polypectomy bleeding, perforation or cardio-respiratory events will be registered. Those complications will be considered if surgery or hospital admission is required.

NCT ID: NCT04825990 Recruiting - Clinical trials for Nasopharyngeal Carcinoma

Pembrolizumab and Olaparib in Recurrent/Metastatic, Platinum Resistant Nasopharyngeal Cancer

POINT
Start date: March 24, 2022
Phase: Phase 2
Study type: Interventional

Recurrence rate after curative treatment for locally advanced Nasopharyngeal carcinoma (NPC) is reported varying from 15% to 30% of cases, while approximately 5-11% of patients present with de novo metastatic disease. In NPC, the immunogenicity of the cancer cell is derived from accumulated somatic mutations, but also from genomic and proteomic differences between host and Epstein Barr Virus (EBV). However, anti-cancer immune response tends to be feeble. This impaired anti-cancer immunity could be attributed to multiple factors including strategies to escape anti-cancer immunity. One of this is switch to immunosuppressive microenvironment, as well as aberrant negative co-stimulatory signals like PD-L1, that is over expressed in NPC. In 2017, the landmark KEYNOTE-028 trial firstly reported promising antitumor activities and safety profiles of pembrolizumab in previously treated RM-NPC Overall, after the treatment of PD-1 inhibitors, about 25% and 60% of the recurrent or metastatic nasopharyngeal carcinoma patients achieved ORR and DCR, respectively, with a profile of toxicities in line with the use of immune checkpoint inhibitors in other diseases. Recently, it was found that some non-BRCA-mutated tumors often harbor other alterations in HR genes except for germline BRCA deleterious mutations, thus making these tumors could benefit from PARPi treatment. PARP could contribute to resistance to chemotherapy induced DNA damage, NPC cell platinum resistant could use PARP to repair and escape apoptosis. In nasopharyngeal carcinoma PARP1 is overexpressed in comparison with normal nasopharyngeal cells, LMP1 (latent membrane protein one) activates PARP1 and increases Poly(ADP-ribos)ylation (PARylation) through PARP1. A preclinical study demonstrates that LMP1+ cells are more sensitive to PARP1 inhibition. After receiving PARPi treatment, accumulated chromosome rearrangements generate plenty of neoantigens and elevate the immunogenicity of tumor, PARPi-mediated acute inflammation remodels tumor immune microenvironment and drives a systemic Th1-skewing immune response. Patients in the POINT trial will receive pembrolizumab 200 mg intravenously (IV) on Day 1 of every 3-week dosing cycle (Q3W) and olaparib 300 mg capsules twice a day (BID) every day starting from Day 1 of Cycle 1. Treatment with protocol therapy will continue until objective disease progression, any prohibitive toxicity or until a maximum of 35 treatment cycles (up to 2 years).

NCT ID: NCT04724590 Recruiting - Clinical trials for The Aim of Our Study is to Prospectively Evaluate the Optic Neuropathy in Nasopharynx Cancer Patients

OPHTHALMOLOGIC EVALUATION OF RADIATION-RELATED OPTIC NEUROPATHY FOLLOWING IMAGE GUIDED INTENSITY-MODULATED RADIATION THERAPY (IMRT) FOR NASOPHARYNGEAL CARCİNOMA

ORONIN
Start date: December 3, 2020
Phase: N/A
Study type: Interventional

Primary treatment in nasopharynx cancers is radiotherapy (RT) or chemoradiotherapy (CRT) depending on the stage of the tumor. According to the guidelines, the dose of radiotherapy for primary tumors varies between 66-70 Gy. In consideration of modern radiotherapy techniques like IMRT with systemic chemotherapy for nasopharyngeal cancer, loco-regional control has been perfect. However, the rate of late complications from treatment, many of which are irreversible, is still high. Radiation-related optic neuropathy is the late complication that optic nerves might be affected during the radiotherapy due to the close location of the nasopharynx. Incidence of this is 8.7-9% in head and neck cancer and is observed between 2-9 years after RT. Painless, irreversible, and progressive vision loss usually occurs, and the pallor of optic disc margins, retinal vein dilatation, bleeding, and neovascularization are in the ophthalmic examination. The risk of optic neuropathy increases when the tumor is in close contact with optic nerves, radiation dose, concurrent chemotherapy used, history of diabetes or hypertension. The aim of our study is to prospectively evaluate optic neuropathy in nasopharynx cancer patients treated in our clinic.
