NCT ID: NCT05482880 Recruiting - Quality of Life Clinical Trials

Decisional Conflicts, Health-related QoL and Satisfaction With Care in High-risk cSCC in the Head-neck Region

Start date: February 28, 2022
Phase:
Study type: Observational

Patient reported outcomes in patients with high-risk cutaneous squamous cell carcinoma in the head-neck region are an important part of the complex care for these patients. Health-related quality of life, decision conflicts in the choice of treatment and satisfaction with care have not yet been sufficiently studied in this patient group.

NCT ID: NCT04266327 Recruiting - Brachytherapy Clinical Trials

RISI in the Treatment of Recurrent Metastatic SCC of Thoracic Inlet Lymph Nodes

Start date: May 1, 2020
Phase: N/A
Study type: Interventional

The malignant tumor at the thoracic entrance is difficult to be surgically removed, and radiotherapy or radiotherapy based comprehensive treatment is often chosen at the initial diagnosis. However, for patients with recurrence after radiotherapy, there is basically no ideal local treatment.The Radioactive i-125 Seed Implantation (RISI) therapy is characterized by high dose within the tumor target area and low dose to surrounding normal tissues, and its radiation dose rate is low, which theoretically benefits the protection of normal tissues and is more suitable for the salvage treatment of recurrent lesions after radiotherapy.3 d printing template technology is through the advance of the preoperative plan design and optimization, to achieve better avoid endanger organs, template of individualized and human body surface after laminating, registration accuracy, its guide pillar to precise control the direction of the needle, the present data show that in the template with CT guided by solid tumors as well had significantly higher accuracy, as the actual target dose of basic postoperative can reach the design request of the preoperative planning, so the application of 3 d printing template helps to further improve the operation efficiency and safety, also has potential promotion effect to curative effect. The purpose of this study is: (1) Observe the efficacy, toxicity and side effects of 3d-printed template assisted ct-guided RISI in the treatment of recurrent metastatic squamous cell carcinoma of thoracic inlet lymph node after radiotherapy, and evaluate its safety and effectiveness; (2) to explore the relationship between the efficacy, toxicity and side effects of relapsed metastatic squamous cell carcinoma of thoracic inlet lymph node after radiotherapy with different RISI doses;(3)the related influencing factors affecting the effect/toxicity of RISI in the treatment of relapsed lymph node metastatic squamous cell carcinoma at the thoracic inlet after radiotherapy were analyzed.

NCT ID: NCT04142489 Completed - Clinical trials for Squamous Cell Carcinomas

In Vivo Damage Induced bu UV in the Epidermis of the Scalp

Start date: February 1, 2021
Phase: N/A
Study type: Interventional

Squamous cell carcinomas (SCC) are the second most common skin cancer in humans. The incidence of SCCs in the USA in 2012 was estimated at 700,000 casesSCCs have a metastatic course in 3% to 5% of cases that is of poor prognosis. In men, the SCCs of the scalp represent the most frequent location of the head and neck, the 3rd location of the whole body. The SCCs of the scalp are more undifferentiated than in other locations. In addition, actinic keratoses of scalp, precursors of SCC, are more resistant to treatment than in other areas. These particularities of the SCCs of the scalp suggest the existence of specific factors at the epidermis level of the scalp. UV-induced damage to DNA is the defining event in skin photocarcinogenesis. It has already been shown that DNA damage induced by UV and the kinetics of repair of this damage may vary with age or phototype of patients, but the topographic variation of DNA damage has never been studied, although it is known that gene expression in skin cells may differ from one region of the body to another. the hypothesis is therefore that the particular characteristics of KAs and SCCs at the scal level could be explained by an increased sensitivity to UV-induced damage. It is planned to study UV-induced damage and its repair at the scalp level in humans compared to the forearm.

NCT ID: NCT01706939 Active, not recruiting - Clinical trials for Squamous Cell Carcinomas

The Quarterback Trial: Reduced Dose Radiotherapy for HPV+ Oropharynx Cancer

Start date: September 1, 2012
Phase: Phase 3
Study type: Interventional

This trial aims to directly compare a reduced radiation dose to the standard of care in HPVOPC for non-inferiority, thus allowing for direct comparison of outcomes between the two groups. The study hypothesis is that LRC and PFS at 3 years for reduced dose CRT are non-inferior to standard dose CRT.

NCT ID: NCT01532453 Terminated - Actinic Keratoses Clinical Trials

Prevention of UV-induced Carcinogenic Skin Alterations in Immunosuppressed Solid Organ Transplanted Patients

Start date: November 2010
Phase: Phase 3
Study type: Interventional

The purpose of this trial is to investigate the prevention of actinic keratoses and squamous cell carcinomas by local application of MD-3511356 in comparison to standard sun protection measures in immunosuppressed solid organ transplant recipients.
