Filter by:Does the tumor thickness value of buccal squamous cell carcinomas, predict cervical nodal metastasis in clinically and radio-graphical neck negative (N0) thus sparing such patients unnecessary surgical procedures and it's associated morbidities? The aim of the study is to evaluate the prognostic value of tumor thickness cut off 4 mm in predicting cervical nodal metastases in a population of Egyptian patients presenting with Buccal Squamous Cell Carcinoma. The hypothesis is that patients with tumor thickness less than 4 mm will present with significantly less cervical nodal metastasis.
Non-small cell lung cancer has the highest morbidity and mortality in China，and platinum-based chemotherapy is the standard first-line treatment for the wild-type NSCLC,however the overall survival still less than one year.Anlotinib is a kinase inhibitor of receptor tyrosine with multi-targets, especially for VEGFR2、VEGFR3、PDGFRβ and c-Kit, which has strong effect of anti-angiogenesis.This study is aim to evaluate the efficacy and safety of the combination regimen of anlotinib plus platinum-based chemotherapy as first-line treatment for NSCLC.
As a 2nd generation EGFR-TKI that irreversibly binds to EGFR receptors, afatinib is currently recommended as the standard first-line treatment for EGFR mutation-positive lung cancer, and clinical studies are also being actively conducted in other types of carcinomas characterized by EGFR gene mutation and overexpression. The overall results from previous studies of gefitinib and erlotinib as EGFR TKIs , as well as from preceding studies of afatinib - a 2nd generation EGFR TKI - suggest the possibility of an effective therapy in esophageal cancer or squmaous lung cancer. In this phase II trial, afatinib shall be administered to patients with squamous cell carcinoma of esophagus or lung squamous cell carcinoma to evaluate its effects and toxicity. Also, biomarkers to predict responses to afatinib shall be explored through further studies.
Oral squamous cell carcinoma (OSCC) are considered as a one of the most malignant cancers. It has prognosis due to its distant metastasis and obvious destruction which lead to low survival rate. The conventional treatment modalities such as surgery, radiotherapy and chemotherapy are only the suitable strategies until now. Investigators cannot ignore the serious side effects of chemotherapy such as gastrointestinal upset, bone marrow suppression which cannot be overcome. For all these complications, there is a great need and demand to discover a new agents and strategies for treating OSCC. Licorice extract, especially Licochalcone A, is one of many natural extracts that have used as a traditional in treatment of inflammation, microbial infections. Regarding antitumor effect, Licochalcone A reveals interesting results in programmed cell death and apoptosis in cancer cells such as prostate, bladder, colon and gastric cancer.
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.
To compare the Disease free survival (DFS) rate of a preoperative cetuximab treatment followed by operation and postoperative radiation-cisplatin-cetuximab treatment paradigm for advanced oral cavity cancer, , with the DFS rate of historical controls (from the RTOG 9501 and EORTC 22931 studies in which treatment was with surgery followed by radiotherapy and cisplatin) with a similar stage of the disease.
Translocator protein (TSPO) is a intracellular protein that is found primarily in the outer membrane of the mitochondria that is encoded by the TSPO gene. It has been found that TSPO expression in the skin correlates with cell proliferation and differentiation. Many studies have shown that TSPO overexpression in solid malignancies such as in ovarian cancer, colon cancer, and others, was also found to correlate with more aggressive cancer behavior. Working Hypothesis and Aims: Previous studies described an aberrant expression of TSPO levels in solid malignancies as compared to normal tissues. It is assumed that this aberration can be found in cuntaneous malignancies as well. The occurrence of this aberration may lead to the understanding of the mechanism of TSPO involment in the cutaneous malignancy, and in malignancies in general. Methods: The study will be carried out on surgically resected skin lesions suspected to SCC or BCC, which will be removed as part of the surgical routine treatment. The excision will be made in elliptic shape including the lesion and a part of normal skin surrounding it. A sample will be taken from the central part of the lesion and from the external extremity of the normal tissue. Western Blot will be conducted to detect the expression of TSPO. Binding activity with the TSPO specific ligandwill also be determined. Expected Results: We expect to observe either (a) a higher level of TSPO expression and a lower binding activity in malignant tissue compared with healthy control tissue or (b) a higher level of TSPO expression and a lower binding activity in malignant tissue compared with healthy control tissue. Importance: Until today, only a very small number of studies have examined TSPO in cutaneous malignancies, and these only examined TSPO expression. Our study will also measure the binding activity of TSPO in cutaneous malignant tissues compared to normal tissues
