Active clinical trials for "Squamous Cell Carcinoma of Head and Neck"

The study is designed to measure salivary matrix metalloproteinase-1 (MMP-1) using the enzyme-linked immunosorbent assay (ELISA) we developed previously in patients with oral potentially malignant disorders (OPMD), oral squamous cell carcinoma (OSCC), and healthy participants. The purpose of this study is to evaluate the potential of the newly developed salivary MMP-1 ELISA as an adjunctive tool to aid in diagnosis of OSCC.

This pilot study seeks to evaluate the feasibility of measuring the proximal effects of concurrent chemoradiotherapy (CRT) on the expression of potential therapeutic target molecules in Head and Neck Squamous Cell Carcinoma (HNSCC). Specifically, this study proposes to evaluate the extent to which CRT induces the differential expression of components along two critical, and potentially interdependent, molecular pathways: the arachidonic acid and epidermal growth factor receptor (EGFR) signaling pathways.

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..

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).

A Post-marketing Surveillance Study to Evaluate the Effectiveness and Safety of Docetaxel-Based Chemotherapy

The aim of this study was to examine molecular alterations on the protein level in lesions of oral lichen planus (OLP), oral squamous cell carcinoma (OSCC) and healthy mucosa. Global protein profiling methods based on liquid chromatography coupled to mass spectrometry were used, with a special emphasis on evaluation of deregulated extracellular matrix molecules expression, as well as on analyses of insulin-like growtg factor 2 (IG2F) and insulin-like growth factor 2 receptor (IGFR2) expression in healthy mucosa, OLP and OSCC tissues by comparative semiquantitative immunohistochemistry. Mass spectrometry based proteomics profiling of healthy mucosa, OLP and OSCC tissues (and accompanied histologically unaltered tissues, respectively) identified 55 extracellular matrix proteins. Twenty among identified proteins were common to all groups of samples. Statistically significant difference between final IGF2 and IGF2R IRS scores in favour to IGF2R may further corroborate the IG2FR antitumor role in OLP and OSCC where it acts as a negative regulator of IGF2 activity.

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).

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.

Trismus Prevention, Diagnosis and Management: Radiotherapy Planning, Early detection, and Physical Therapy Intervention

The primary endpoint will be acute toxicity. Secondary endpoints included: late toxicity and quality of life; loco-regional control, disease free survival and overall survival.
