Filter by:Esophageal cancer is a highly lethal disease, and its incidence is still increasing in the world. Recent advances in image-enhanced techniques such as Lugol chromoendoscopy and narrow band imaging, the number of patients with early esophageal squamous cell neoplasias (ESCNs) detected has markedly increased. Endoscopic submucosal dissection (ESD) enables en bloc resection of the neoplasia, and the resected specimen allows for a pathological assessment to evaluate the curability. However, the patients who received complete ESD for early ESCNs frequently developed metachronous recurrence. The cumulative metachronous recurrence rate at 5 years was 50%, and the mean annual incidence of newly diagnosed metachronous tumors was 10%. Among them, those with "speckled" lugol staining pattern over the esophageal background mucosa have the highest risk and should be seen as a precancerous lesion of ESCCs. This issue is gaining attention in the era of endoscopic treatment, but currently there was no appropriate strategy to prevent the tumor recurrence in these high-risk subjects. Endoscopic radiofrequency ablation (RFA) is a rapidly evolving therapeutic modality, and recent studies have shown its efficacy and safety for eradicating for flat type early ESCNs. To search a best strategy for the prevention of ESCNs, the investigators thus propose a hypothesis that the preemptive RFA for esophageal "speckled" lugol background mucosa may prevent the metachronous neoplastic recurrence after complete endoscopic resection.
A window of opportunity study which would allow brief treatment of HPV negative SCCHN with a CDK4/6 inhibitor, in the pre-operative setting, with biomarker analyses of pre and post treatment tissue. Given that the standard treatment for this population is surgical resection, this would not impact or alter standard therapy for this population. The goal will be to learn more about the alterations in pRB1 levels, as well as other signaling markers, in order to be able to eventually plan a biomarker driven treatment study.
This is a post-marketing study of patients who started nivolumab as first- or second-line therapy for metastatic melanoma or as second-line therapy for metastatic squamous non-small cell lung cancer (SqNSCLC) , metastatic non-SqNSCLC, metastatic renal cell carcimona (RCC), or recurrent or metastatic squamous cell carcinoma of the head and neck cancer (SCCHN), or third-line therapy for classical Hodgkin lymphoma (cHL) in Mexico.
Single centre, single arm, preoperative window of opportunity study with a biomarker endpoint (expression profiling by RNA sequencing). Patients with resectable, histologically confirmed head and neck squamous cell carcinoma (HNSCC) for whom surgical treatment is planned as definitive management will be eligible.
This is an open-label, randomized, controlled trial. At the end of a 28-day screening period, all eligible subjects will be randomly assigned into treatment Arm A or B in a 1:1 ratio. Subjects in Arm A will receive a maximum of 6 cycles of chemotherapy (cisplatin plus paclitaxel) and cetuximab weekly in the absence of progressive disease (PD), as assessed by the Investigator, and unacceptable toxicity. After 6 cycles of treatment, subjects who derive clinical benefit will continue treatment with cetuximab as monotherapy until either PD or unacceptable toxicity. Subjects in Arm B will receive the same chemotherapy regimen as Arm A alone for a maximum of 6 cycles in the absence of PD and unacceptable toxicity.
A small group of skin cancers of the head and neck, called resected cutaneous squamous carcinomas, are more aggressive than most cancers of this type, even after being treated with standard therapy. This trial will use stronger treatment to look at the safety and effectiveness (efficacy) of combining a drug called Pembrolizumab with radiation after a cancer has already been treated to suppress secondary tumor formation in high risk cutaneous squamous cell cancer of the head and neck. Primary Objective To assess safety by looking at the people with dose limiting responses
This is a single arm Phase II study for patients with recurrent or metastatic squamous cell carcinoma of the head and neck, who are previously treated with a platinum based regimen or with an immune checkpoint inhibitor. The primary objective is to evaluate the efficacy of the combination of cetuximab and afatinib.
This is a Phase 1/2 study of the combination of Ad-p53 administered intra-arterially in combination with oral metronomic capecitabine or pembrolizumab in patients with unresectable, refractory liver metastases of colorectal carcinoma (CRC) and other solid tumors, including primary hepatocellular carcinoma (HCC). A third arm will study the intra-tumoral injection of Ad-p53 combined with nivolumab infusions in recurrent head and neck squamous cell cancer (HNSCC). This safety study has a standard 3+3 design for arms A and B; .HNSCC will be placed in a single dosing cohort. The Maximum Tolerated Dose (MTD) will be determined as well for intra-arterial infusions, and the entire study will determine the general efficacy using RECIST 1.1 and Immune-Related Response Criteria. Safety will be followed using the CTCAE listings for adverse events.
Investigators will determine whether a treatment paradigm of up-front neck dissection, to more accurately pathologically stage patients, minimizing the number of treatment modalities in patients with low risk oropharyngeal squamous cell carcinoma, can improve quality of life.
Primary objectives: 1. Evaluate the feasibility of rapidly accruing 30 participants with recurrent metastatic head and neck squamous cell carcinoma for the development of patient derived xenographs (PDX) from fresh, real time biopsies in which sensitivity to < 4 Ontario funded chemotherapeutic regimen will be tested. Written feedback to the primary oncologist will be provided. 2. There is also a curative intent cohort of 30 participants undergoing surgical resection with curative intent. These PDX models will undergo exome sequencing with written feedback. 3. Feasibility in both surgical and recurrent cohorts will be a measure of i) engraftment rate, ii) patient status at the time of drug testing completion and iii) rate of accrual.
