Filter by:The aim of the current study is to assess the validation of Bmi-1 detection at both protein and molecular levels in oral epithelial dysplasia and oral squamous cell carcinoma as a biomarker for early cancer detection versus biopsy embedded in paraffin blocks.
In vitro study to examine whether luteolin and nano-luteolin exert an inhibitory effect on tongue squamous cell carcinoma cell line by inducing apoptosis, and to assess if nano-luteolin has more efficient apoptotic activity than luteolin on tongue squamous cell carcinoma cell line.
The purpose of this study is to determine the efficacy of adjuvant radiotherapy for esophageal squamous cell carcinoma with positive circumstantial resection margin.
This pilot study will evaluate the effectiveness of using photodynamic therapy for treatment of cutaneous squamous cell in situ (SCCis). Our hypothesis is that PDT will be effective for treating SCCis. This study will also secondarily evaluate the tolerability of using photodynamic therapy for treatment of SCCis. Investigators plan to enroll 40 subjects with biopsy proven SCCis. Exclusion criteria include lesion in high-risk site (head, neck, hands, feet), previous severe adverse reaction to topical 20% aminolevulinic acid (Kerastick), previous severe adverse reaction to blue light (BLU-U), allergy to Tegaderm, primary or secondary immunosuppression, history of > 6 skin cancers in the past year, photosensitizing condition such as lupus, or sensitivity to porphyrins. Age, gender, size, and location of the SCCis will be recorded. All subjects will receive surgical treatment of their SCCis. The control group will undergo a surgical excision of the tumor. After the excision, subjects will be asked to fill out a satisfaction survey. The intervention group will receive PDT plus surgical treatment. Photographs of the lesion will be taken at each study visit. Subjects in the intervention group will then undergo the study procedure of application of topical 20% 5-ALA (Levulan Kerastick; DUSA Pharmaceuticals) to the SCCis. At 3-5 weeks after the initial treatment, the subject will repeat the 3-hour ALA incubation and blue light exposure. At 6 months after the last treatment, subjects in the intervention group will return for clinical follow-up and surgical excision of the lesion. After excision, the specimen will be sent for processing by pathology and subjects will be asked to fill out a satisfaction visual analog scale. All slides will be read by a board-certified dermatopathologist. Side effects will also be monitored using the same graded scale described previously. Mild adverse events that have been associated with PDT, including erythema, skin crusting, superficial blistering, hypopigmentation, and hyperpigmentation. These reactions usually occur during or immediately after the PDT treatment.
The purpose of this study is to determine the impact of tumor growth velocity on the survival of patients with hea and neck squamous cell carcinoma treated by (chemo-)radiotherapy. Patients with stages I to IV oropharyngeal primary squamous cell carcinoma (OPSCC) elected for radiotherapy or radiochemotherapy with curative intent will be selected. Tumor volume and number and size of pathological neck lymph nodes (small diameter > 1 cm) will be assessed on diagnostic CT-scan (DiCT) and treatment planning CT-scan (RtCT) using the summation of areas technique. Tumor progression and tumor doubling time will be calculated based on DiCT and RtCT. Tumor proliferation will be assessed on biopsy specimens by Ki67 immunohistochemistry and mitotic index. HPV status will be evaluated by PCR and p16 immunohistochemistry. Ulcerative or exophytic aspect will be noticed. Tumoral kinetics patterns will be correlated with disease free survival and overall survival of patients with HNSCC. These patterns will be compared to HPV status and proliferation markers in order to study their clinical signification [time frame: 5 years] and develop predictive markers of tumor progression for head and neck cancers.
Head and neck Squamous Cell Carcinoma (HNSCC) is one of the most common head and neck malignant tumors .Investigators found that several patients with early TNM stage and poor differentiated HNSCC had poor prognosis, yet someone with advanced TNM stage and well differentiated HNSCC had good prognosis. Hence, Investigators suggested that prognosis factors and survival rates probably related to the differentiation of HNSCC, and prognosis factor of poorly differentiated HNSCC were rare discussed and controversy. Investigating the prognostic factors of poorly differentiated HNSCC is undoubtedly crucial.
The purpose of this study is to determine whether docetaxel, cisplatin, and capecitabine (DCX) are effective as the neoadjuvant chemotherapy before esophagectomy in patients with loco-regional esophageal squamous cell carcinoma (ESCC).
Verify the effect and the incidence of oral mucositis of concurrent chemoradiotherapy in locally advanced squamous cell carcinoma of the head and neck versus concomitant cetuximab with radiotherapy after neoadjuvant chemotherapy. The predictive effect of Apurinic/apyrimidinic endonuclease 1(APE1)/ Ref-1 protein and Apurinic/apyrimidinic endonuclease 1(APE1)/Ref-1 antibody on oral mucositis.
The purpose of this study is to determine which regimen is better for esophageal squamous carcinoma in concurrent chemoradiation(CCRT),paclitaxel or S1 plus cisplatin.
Chemotherapy is the main treatment method for patients with Esophageal Cancer. However, Relapse remains the major cause of treatment failure.Biological therapies such as CIK stimulate the immune system and stop tumor cells from growing. A series of studies reported that cytokine-induced killer cells (CIK) have a broad anti-tumor spectrum. The investigators suppose that CIK will improve the prognosis. Combining chemotherapy with biological therapy may kill more tumor cells. In this study, the patients will be treated with CIK cells after chemotherapy. The purpose of this study is to evaluate the efficacy of CIK for Esophageal Cancer.
