Active clinical trials for "Carcinoma, Squamous Cell"

The aim of this study is to explore whether endostar combined with IP as treatment could improve progression-free surial time (PFS) and to evaluate the safety of the chemotherapy regimens

The purpose of this study is to observe and evaluate the efficacy and safety of anti-PD-1 antibody SHR-1210 combined with nimotuzumab as second-line therapy in patients with advanced cancerous esophageal squamous cell carcinoma.

In order to search for effective and low toxicity anti-tumor angiogenesis drugs, jiangsu hengrui pharmaceutical co., ltd. developed the high-efficiency VEGFR2 tyrosine kinase inhibitor apatinib. This drug is mainly used to treat malignant tumors by inhibiting VEGFR2 to play an anti-angiogenic role. Both in vivo and in vitro experiments have shown that apatinib has good tumor growth inhibition activity for lung cancer. This study aims to further confirm the effectiveness and safety of apatinib third-line treatment for patients with advanced lung squamous cell carcinoma.

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.

Patients enrolled for the study, who are eligible for NACT, will undergo a pre-treatment workup comprising of Evaluation Under Anesthesia (EUA) for tumor Mapping and tissue biopsy along with a PET-CT scan. Subsequently, they would undergo 3 cycles of NACT (weekly thrice) with DCF. They would be reassessed with PET-CT and EUA +/- biopsy after the end of the third cycle. Those who are achieving CR would undergo adjuvant CTRT. Subjects who have a PR in the PET-CT scan will be re-classified based on the biopsy report. If they remain in the PR group they will undergo surgery but if the biopsy in is negative for malignancy, they will undergo adjuvant CTRT. Those subjects with SD or PD would undergo surgery. Subsequently, further radiation and/ or chemotherapy will be decided based on the final histopathology (of the surgical specimen) reports. PET-CT and EUA +/- HPE analyses would be repeated on follow-up after 3 months of treatment completion.

This is an open-label, randomized, controlled trial. At the end of a 28-day screening period, all eligible subjects will be randomly assigned into treatment Arm A or B in a 1:1 ratio. Subjects in Arm A will receive a maximum of 6 cycles of chemotherapy (cisplatin plus paclitaxel) and cetuximab weekly in the absence of progressive disease (PD), as assessed by the Investigator, and unacceptable toxicity. After 6 cycles of treatment, subjects who derive clinical benefit will continue treatment with cetuximab as monotherapy until either PD or unacceptable toxicity. Subjects in Arm B will receive the same chemotherapy regimen as Arm A alone for a maximum of 6 cycles in the absence of PD and unacceptable toxicity.

Primary Objective: To determine the 2-year distant failure rate of maintenance tegafur-uracil in patients with squamous cell carcinoma of oral cavity with extracapsular spreading of lymph nodes. Secondary Objectives: To determine the 2-year locoregional failure rate. To evaluate the 2-year overall survival (OS) rate. To evaluate the 2-year progression-free survival (PFS) rate. To assess the safety profiles.

Esophageal cancer is a common malignant tumor in china, occupies the second place of malignant tumor morbidity and mortality, the overall 5-year survival rate less than 20%.

Smart Matrix is a sterile, single layer dermal replacement scaffold. The scaffold consists of a porous matrix of cross-linked human fibrin plus alginate that has been designed and optimised to facilitate wound closure and healing through cellular invasion.

This is an open-label, phase II study of KN046 combined with chemotherapy and palliative radiotherapy in patients with recurrent or metastatic esophageal squamous cell carcinoma to evaluate the safety, efficacy and tolerance.
