Active clinical trials for "Carcinoma, Squamous Cell"

This study aims to characterize the profile and outcomes for patients with Squamous Cell Carcinoma of the Lung (SqCC) who progress on 1L pembrolizumab in combination with platinum based chemotherapy and receive afatinib as second line (2L) therapy.

Oral squamous cell carcinoma (OSCC) has the highest annual increase in the rate of death among the top 10 leading cancers in Taiwan. This research aimed to explore whether increased anti-tumor immunity for OSCCs reduces the recurrence rate or improves survival. We first identified CD33+/CD11b+/HLA-DR-/low/CD14+/- as myeloid-derived suppressor cell (MDSC) surface markers by using flow cytometry to compare the MDSC frequency of OSCCs with blood samples from healthy donors (HDs). We then re-confirmed the suppression of T cell proliferation and function achieved by co-culturing with OSCC-educated MDSCs. We subsequently explore whether using particulate β-glucan as a food-grade supplement promotes the human immune system via subversion of immune modulatory MDSCs. Lastly, we correlated clinicopathological parameters with MDSCs and β-glucan administration to examine anti-tumor immunity, and to predict the therapeutic effect and prognosis in OSCC patients..

Squamous Cell Carcinoma Antigen (SCCA) contributes to the pathogenesis of psoriasis by inhibiting cell apoptosis, exacerbating epidermal hyperplasia and skin inflammation. Three studies have shown a correlation between blood levels of SCCA and the severity of psoriasis. Clinical scores of psoriasis severity are used in consultation to guide treatment of the disease (initiation of systemic therapy, dose escalation) but they suffer from several pitfalls: lack of inter- and intra-observer reproducibility, consumption of medical time. A readily available, inexpensive (24 euros) blood marker could be an interesting alternative to these clinical scores.

The purpose of this observational study is to collect real-world data that describes treatment patterns and clinical outcomes in participants with first line recurrent/metastatic squamous cell carcinoma of the head & neck (1L R/M SCCHN).

Concomitant chemoradiotherapy improves overall survival in patients with locally advanced head and neck squamous cell carcinoma (LA-HNSCC) compared to radiotherapy alone. Cisplatin 100 mg/m2 at day 1, 22 and 43 is widely used but results in considerable acute and late toxicity. Three cycles of carboplatin plus 5-fluorouracil (5-FU) is an accepted alternative but both chemotherapy regimens have not been compared prospectively. The aim of this study is to compare tolerability, efficacy, toxicity and quality of life in patients with LA-HNSCC treated with concomitant cisplatin and carboplatin plus 5-FU.

The purpose of this research study is to test the safety and effectiveness of the investigational study vaccine, called TVGV-1. The study will test the vaccine in women with high grade HPV cervical infection.

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 investigators main objective is to show that OSNA technique is as accurate as pathological analysis (frozen section / HE staining and immunochemistry) to detect occult lymph node metastasis (micro and macrometastasis).

The primary objective of this study is to (1) determine whether local injection of lidocaine used during Mohs surgery will elevate serum lidocaine concentrations to a level that could cause systemic symptoms and (2) determine whether sustained high levels of serum lidocaine occur after intralesional anesthesia on the face and neck. This study is a cross-sectional study of 10 subjects with basal cell carcinoma or squamous cell carcinoma of the face or neck requiring Mohs micrographic surgery. The study will consist of a brief questionnaire and blood draws during their Moh's surgical procedure.

The purpose of this study is to determine the difference of skin carotenoid levels between subjects with previous squamous cell carcinomas (SCC), subjects with previous basal cell carcinomas (BCC) and a control group.
