Active clinical trials for "Carcinoma"

Patients with hepatocellular carcinoma often die from intrahepatic disease because current treatment options are limited. Local treatment using 166Ho-radioembolization (166Ho-RE) offers a safe and effective treatment. Because 166Ho-microspheres are used as a scout dose for treatment simulaton and for the actual treatment itself, a tailored approach can be used. This concept has proven to be more predictive than the 90Y-radioembolization concept (current standard-of-care), which is a based on a surrogate scout dose (i.e. 99mTc-MAA). A personal treatment plan may be used for 166Ho-radioembolization to optimize efficacy, based on scout dose distribution. However, individualized treatment planning inherently leads to treatment doses that deviate from the currently approved 'one-size-fits-all' approach (i.e. 60 Gy average absorbed dose for all patients). Therefore, safety of individualized 166Ho-RE will be evaluated first to validate safety and confirm safety thresholds. These thresholds will be used in subsequent randomized controlled studies.

Percutaneous ablation (PA) is the only non-surgical curative treatment of hepatocellular carcinoma (HCC). Due to its excellent tolerance, particularly in patients with portal hypertension or bearing comorbidities, it now represents in France nearly 70% of the first-line curative treatment of "in Milan" tumours. For HCC less than 3 cm, ideal indication for percutaneous ablations, results of monopolar radiofrequency ablation (mRFA), are excellent with only 5% of reported non-tumoral control after a first procedure. In addition to mRFA the arsenal of ablations has grown considerably with the emergence of new techniques which allow the expansion of indications for PA, especially in patients with poor prognostic tumors or relatively advanced beyond the Milan criteria. In this setting, multibipolar mode using no touch technique (mbpRFAnt) increases the tumour volume than can be ablated, allowing the removal of large tumors> 5 cm. Inadequate tumour control is then de facto greater in these situations, around 20%. Difficult-to-access tumors can furthermore be treated by percutaneous irreversible electrotroporation (IRE). Despite a tumor burden accessible for curative ablation, a phenotype of "aggressive" HCC characterized by high rates of local recurrences is yet to be defined. Up to now, several characteristics might define this subtype with a poor-prognosis and include 1) high serum alpha-foetoprotein (AFP) levels, 2) radiological infiltrative form, and 3) histological macrotrabecular subtype. Based on these characteristics, median recurrence-free survival of these patients is usually below 10 months. High serum AFP level is a well-known predictor of HCC recurrence following curative procedure. In patients treated by percutaneous ablation, regardless of the technique used and irrespective of tumor burden, high baseline serum AFP level has tenaciously been reported as an independent predictor or recurrence.. More recently, the radiological description of infiltrative HCC (as opposed to mass-forming) has been identified as an aggressive from of HCC with a poor prognosis even when eligible for ablation. This aspect is often associated with infra-clinical invasion of the portal veins (PV), leading to poor prognosis. Finally, a "massive macrotrabecular" (MTM) histological subtype of HCC associated with specific molecular features has recently been described. This MTM-HCC subtype, reliably observed in 12% of patients eligible for curative treatment, represents an aggressive form of HCC is an independent predictor of early and overall recurrence following PA, which is retained even after patient stratification according to common clinical, biological, and pathological features of aggressiveness. The idea of optimizing HCC curative treatments using adjuvant biotherapy, particularly in patients with poor-prognosis tumors in curative intent, is particularly attractive. One trial in adjuvant setting was conducted, the STORM trial, that tested the benefit of sorafenib in curative intent of in Milan HCC. This negative trial included patients within Milan HCC, with an expected low rate of recurrence with only few patients treated by PA. Lenvatinib is a multikinase inhibitor which has been recently approved as firs-line therapy for advanced HCC. The investigators assume that lenvatinib could have also a synergistic local action with PA in two ways. First, given as neoadjuvant regimen, lenvatinib by reducing tumor and liver perfusion could decrease the global heat sink effect associated with loco-regional blood microcirculation during PA. Second, by carrying on in adjuvant treatment, lenvatinib could decrease the magnitude of non-specific inflammatory angiogenesis around the treatment zone, therefore reducing the risk of locoregional (intrasegmental) cells tumor spreading or promotion. Given the dismall prognosis of the aforementioned poor-prognosis HCC eligible for PA with an overall median recurrence-free survival below 10 months, the investigators hypothesis is that addition of Lenvatinib as neo- and adjuvant therapy might increase tumour control in these difficult-to-treat patients. Patients combining either high serum AFP levels, infiltrative form or MTM-HCC histological subtype represent 30% of BCLC A stage HCC patients in expert centers, and are the ideal candidates for such trials. Therefore, the first aim of this proposal is to assess the benefit of lenvatinib in neo- and adjuvant setting combined with curative percutaneous ablation for BCLC A HCC patients considered at high risk of local recurrence (high AFP or infiltrative form or macrotrabecular massive subtype).

Cutaneous Squamous Cell Carcinoma (cSCC) is typically associated with a high tumour mutation burden, with the majority caused by Ultraviolet (UV) exposure (Pickering et al., 2014). The use of this trial using neoadjuvant Pembrolizumab in patients with cSCC who will otherwise undergo highly morbid radical surgical resection has multiple potential advantages, including: Reduction in surgical and radiotherapy morbidity by reducing tumour burden and allowing the appropriate selection of patients to undergo post-operative radiotherapy; Provision of immediate information about pathological response and Access to tissue to provide insight into resistance mechanisms and identification of biomarkers of response. The Investigators hypothesized that the use of neoadjuvant Pembrolizumab could reduce tumour burden allowing appropriate selection of patients undergoing radical surgical resection and adjuvant radiotherapy.

This is a prospective, open label, phase II, randomised, non-comparative clinical trial, evaluating changes in tumour-responsive T-cells following neoadjuvant stereotactic ablative body radiotherapy (SABR) with or without pembrolizumab, prior to nephrectomy, in patients with localised primary clear cell renal cell carcinoma (ccRCC).

This study is a prospective phase II, single arm mono-institutional study conducted in Queen Mary Hospital (Hong Kong) assessing the efficacy and safety of the sequential administration of trans-arterial chemo-embolization (TACE) and stereotactic body radiotherapy (SBRT) with immune checkpoint inhibitors in unresectable hepatocellular carcinoma (HCC) patients.

This phase II/III compares the standard therapy (chemotherapy plus cetuximab) versus adding bevacizumab to standard chemotherapy, versus combination of just bevacizumab and atezolizumab in treating patients with head and neck cancer that has spread to other places in the body (metastatic or advanced stage) or has come back after prior treatment (recurrent). Immunotherapy with monoclonal antibodies, such as atezolizumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Bevacizumab is in a class of medications called antiangiogenic agents. It works by stopping the formation of blood vessels that bring oxygen and nutrients to tumor. This may slow the growth and spread of tumor. Cetuximab is in a class of medications called monoclonal antibodies. It binds to a protein called EGFR, which is found on some types of cancer cells. This may help keep cancer cells from growing. Cisplatin and carboplatin are in a class of chemotherapy medications known as platinum-containing compounds. They work by killing, stopping, or slowing the growth of cancer cells. Docetaxel is in a class of chemotherapy medications called taxanes. It stops cancer cells from growing and dividing and may kill them. The addition of bevacizumab to standard chemotherapy or combination therapy with bevacizumab and atezolizumab may be better than standard chemotherapy plus cetuximab in treating patients with recurrent/metastatic head and neck cancers.

The purpose of this study is to better understand the immune response to basal cell carcinoma (BCC) treated with Photodynamic Therapy (PDT) in order to develop new methods of treating BCC. Previous research suggests that PDT alters the immune response, possibly in a way that could promote better tumor clearance when combined with other treatments. Overall, participation in this study will help the study team better understand the anti-tumor immune response when BCC is treated with PDT.

To evaluate the efficacy and safety of TheraSphereTM yttrium [90Y] glass microsphere in the Chinese patients with inoperable hepatocellular carcinoma.

This pilot study will examine the treatment of basal cell carcinoma (BCC) with laser technology under the guidance of imaging modalities to assist with surgical excision, including optical coherence tomography imaging (OCT) and reflectance confocal microscopy (RCM). The laser modality that we plan to use is the long-pulse Nd:YAG 1064nm laser, which is a nonablative laser already shown to effectively treat BCC. The addition of OCT and RCM has the opportunity to enhance outcomes by better targeting the treatment and permitting more precise monitoring of clearance. OCT is being used to enhance the effectiveness of Mohs Micrographic Surgery of these cancers by elucidating more definitive tumor margins. RCM has been shown to detect changes in the composition of cells consistent with BCC. We propose to use these imaging devices to guide the laser treatment to achieve optimal efficacy with minimized side-effects. Primary outcome measured include complete clearance of the BCC lesion, which will be determined through clinical examination, dermoscopy, imaging (OCT and/or RCM), and saucerization biopsy. Secondary outcome variables include the significance of lesion depth (by OCT and/or RCM), lateral extent (by OCT and/or RCM), BCC type, and anatomical region on rate of clearance and recurrence.

A multicentre, parallel group, randomized controlled Phase II clinical trial evaluating neoadjuvant Atezolizumab/Bevacizumab versus neoadjuvant SBRT in patients with biopsy proven solitary HCC with PVTT involving the portal vein branches. Both arms are considered experimental, and as such, a Simon two-stage design will be initially used within both arms. Only if both arms are deemed of interest for further study will a comparison between arms, using a pick-the-winner design, be conducted. Following the completion of neoadjuvant therapy, study participants will undergo a CT scan or MRI to assess tumour response to neoadjuvant therapy. Hepatic resection will be performed for those participants who meet the surgical resection criteria.
