Filter by:Localized cutaneous squamous cell carcinoma (CSCC) is usually treated by radical surgery with or without radiotherapy. The cure rate is high around 90% of cases (1). Unresectable CSCC represents less than 10% of all CSCC. The prognosis of these advanced forms is poor, without any proven treatment option. The number of studies investigating systemic treatment of advanced or metastatic CSCC is limited, mostly based on phase II trials or case reports. Systemic treatment includes cytotoxic chemotherapy such as cisplatin and 5-Fluoro-uracil (5FU), immunotherapy (interferon alpha) or retinoic acid (13CRa) (1,2). Recently, epidermal growth factor receptor (EGFR) targeting agents have been explored (1,2). The anti-EGFR monoclonal antibody Cetuximab has shown some clinical efficacy in advanced CSCC alone or concomitant with radiotherapy or chemotherapy (3-5). A recent phase II study aimed at investigating the role of Cetuximab in 36 patients with unresectable CSCC (6). The authors reported a disease control rate at 6 weeks of 69% (95% CI, 52% to 84%). The best responses were eight partial responses and two complete responses. There were no Cetuximab-related deaths. There were three related serious adverse events: two grade 4 infusion reactions and one grade 3 interstitial pneumopathy. Grade 1 to 2 acne-like rash occurred in 78% of patients and was associated with prolonged Progression Free Survival (PFS) (6). The authors concluded that regarding the Cetuximab therapeutic index it could be interesting in this particular situation mainly for elderly patient. Unfortunately, the small number of patient included not allowed to draw definitive conclusion. It was interesting to note that the Disease rate control (DRC) with Cetuximab increased of 15% comparatively of DRC with chemotherapy. Additionally it seems that in case of efficacy the functional improvement of Cetuximab-sensitive patients occurred after very few infusions. Taking these data together it seemed logical to design a larger retrospective clinical trial to confirm these results in "real life patients".
The KEO study is a single arm phase II trial including 44 patients with T1N1-2B, T2N0-N2B head and neck squamous cell carcinoma (HNSCC) eligible for curative-intent resection (+/- adjuvant therapy), who receive neo-adjvuant pembrolizumab + epacadostat. The primary objective of this study is to determine rate of major treatment effect (MTE) to neoadjuvant pembrolizumab+epacostat immunotherapy in SCCHN compared to historic data with neoadjuvant pembrolizumab alone.
The purpose of this study is to demonstrate that participants with HPV positive and hypoxia negative T1-2, N1-2c (AJCC, 7th ed.) oropharyngeal squamous cell carcinoma receiving a major de-escalated radiation therapy with 2 cycles of standard chemotherapy is not inferior to comparable subjects treated with the current standard chemoradiation. Accrual for Cohort A has been completed. Cohort B is active and continues to enroll participants where surgery is optional and proton is allowed.
In this study, participants with histologically diagnosed locally advanced esophageal squamous cell carcinoma who have received preoperative cisplatin-based chemoradiotherapy followed by surgery harbouring high risk of tumor recurrence will receive adjuvant cisplatin-based chemoradiotherapy followed by pembrolizumab. The primary study hypothesis is that adjuvant pembrolizumab will improve the 1-year recurrence-free survival rate compared to historical control.
It has been well established that malignant tumors tend to have low levels of oxygen and that tumors with very low levels of oxygen are more resistant to radiotherapy and other treatments, such as chemotherapy and immunotherapy. Previous attempts to improve response to therapy by increasing the oxygen level of tissues have had disappointing results and collectively have not led to changing clinical practice. Without a method to measure oxygen levels in tumors or the ability to monitor over time whether tumors are responding to methods to increase oxygen during therapy, clinician's reluctance to use oxygen therapy in usual practice is not surprising. The hypothesis underlying this research is that repeated measurements of tissue oxygen levels can be used to optimize cancer therapy, including combined therapy, and to minimize normal tissue side effects or complications. Because studies have found that tumors vary both in their initial levels of oxygen and exhibit changing patterns during growth and treatment, we propose to monitor oxygen levels in tumors and their responsiveness to hyperoxygenation procedures. Such knowledge about oxygen levels in tumor tissues and their responsiveness to hyper-oxygenation could potentially be used to select subjects for particular types of treatment, or otherwise to adjust routine care for patients known to have hypoxic but unresponsive tumors in order to improve their outcomes. The overall objectives of this study are to establish the clinical feasibility and efficacy of using in vivo electron paramagnetic resonance (EPR) oximetry—a technique related to magnetic resonance imaging (MRI)—to obtain direct and repeated measurements of clinically useful information about tumor tissue oxygenation in specific groups of subjects with the same types of tumors, and to establish the clinical feasibility and efficacy of using inhalation of enriched oxygen to gain additional clinically useful information about responsiveness of tumors to hyper-oxygenation. Two devices are used: a paramagnetic charcoal suspension (Carlo Erba India ink) and in vivo EPR oximetry to assess oxygen levels. The ink is injected and becomes permanent in the tissue at the site of injection unless removed; thereafter, the in vivo oximetry measurements are noninvasive and can be repeated indefinitely.
The purpose of this study is to test whether 5 fraction stereotactic ablative body radiation (SABR) is safe and improves local control for early state squamous cell carcinoma of the lung. While three fraction SABR is effective for the treatment of early stage non small cell lung carcinoma (NSCLC) of all histologies, it is not safe for many patients. While four and five fraction SABR is safe, recently published data and our institutional data suggests that local control for early stage squamous cell carcinoma of the lung using the current four or five fraction SABR is suboptimal.
The purpose of this study is to assess the efficacy and safety of patients who receive apatinib plus radiotherapy and S-1 for treatment of refractory or metastatic esophageal squamous cell carcinoma.
This is a Phase 1, single-dose, open-label, dose-escalation study. The study will be conducted in three parts (i.e. regimens) in an outpatient setting as follows: - Regimen A: FATE-NK100 as a monotherapy in subjects with advanced solid tumor malignancies. - Regimen B: FATE-NK100 in combination with trastuzumab in subjects with human epidermal growth factor receptor 2 positive (HER2+) advanced breast cancer, HER2+ advanced gastric cancer or other advanced HER2+ solid tumors. - Regimen C: FATE-NK100 in combination with cetuximab in subjects with advanced colorectal cancer (CRC) or head and neck squamous cell cancer (HNSCC), or other epidermal growth factor receptor 1 positive (EGFR1+) advanced solid tumors.
ARTemIS-Eso is a phase I-II, three-level, open-label trial with a dose-expansion cohort at recommended schedule in both esophageal cancer histological groups (squamous cell carcinoma and adenocarcinoma) of RCT and ImT administered prior to surgery.
This is a randomized noninferiority multicenter trial. Patients will be stratified according to the participating hospital. Patients will be randomized to one of the treatment arms. Arm A: Patients will receive surgical resection, including Ivor Lewis esophagectomy or McKeown esophagectomy and systematic lymphadenectomy. Arm B: Patients will receive 5-fluorouracil (5-FU) and cisplatin-based chemotherapy concurrently with radiotherapy. Patients will receive cisplatin (45~60mg/m2) intravenously over 1 hour on day 1 and receive 5-FU (3,200 ~ 4,000mg/m2) intravenously for 4 to 5 days. Treatment will repeat every 3 weeks for 2 courses. Patients will receive a total of 45 Gy irradiation (5 days a week for 5 weeks). Patients will be followed at 3 and 6 months after randomization, then every 6 months for following 2 and half years (up to 3 years after randomization), and 4 and 5 years after randomization. After 5 years, annual follow-up is scheduled up to 10 years after randomization. We will analyze the results primarily with the intention-to-treatment(ITT) analysis, and then secondarily with the per-protocol(PP) analysis as well.
