Filter by:To investigate the efficacy and safety of TQB2618 injection combined Penpulimab and chemotherapy in the first-line treatment of recurrent/metastatic esophageal squamous cell carcinoma compared with Penpulimab combined chemotherapy. The primary efficacy outcomes are progression free survival (PFS) and objective response rate (ORR).
This is a single-arm, multicenter, exploratory study to evaluate the efficacy and safety of AK104 in combination with cisplatin and paclitaxel in the treatment of resectable locally advanced esophageal squamous carcinoma.
1. Determine the correlation between immunohistochemical expression of ERCC1 in laryngeal cancer cells with clinico-pathological variables. 2. Assess the correlation between ERCC1 expression and response to radiotherapy.
This is a randomized open-label multicentre phase III superiority study of the effect of adding SABR to the standard of care treatment pembrolizumab on progression free survival in patients with oligometastases of a squamous cell carcinoma of the head and neck (SCCHN), histological confirmation of the primary disease at first diagnosis, and PD-L1 CPS ≥1. After eligibility check and signing informed consent, all patients will be prospectively enrolled in a 1:1 ratio between current standard of care treatment (pembrolizumab, Arm 1) vs. SABR + standard of care treatment (Arm 2) to oligometastases. Any radical treatment to the synchronous primary/ recurrent primary tumor and/or involved cervical nodes (surgery or radiotherapy), as decided by the local tumor board/ treating physicians, should be completed prior to enrolment.Surgical removal of metastases is allowed for diagnostic purposes or for brain metastases, as long as these metastases count toward the total number of 5 and at least one metastasis is left for treatment with SABR. Such surgical procedures should be performed prior to enrolment.
Cervical lymph node metastasis is the most important prognostic factor of oral squamous cell carcinoma (OSCC). Therapeutic neck dissection (I-V region) has always been regarded as the standard scheme of neck surgery for patients with cN+ OSCC and however, it has brought obvious side effects, which seriously affects the postoperative quality of life of patients. In addition, excessive neck lymph node dissection will also affect the local immune function of patients to some extent and reduce the body's response to immunotherapy. Lymph node metastasis of primary oral squamous cell carcinoma follows certain rules. Most of the metastatic areas are I-II, and low-level metastasis is very rare. Therefore, more than 90% of patients with cN+ oral squamous cell carcinoma who have undergone Therapeutic neck dissection may have suffered from "excessive dissection of area of IV and V". Both the long-term clinical experience of surgeons and a large number of recent retrospective studies show that elective neck dissection (I-III region) is safe enough for patients with oral squamous cell carcinoma of cN1 and part of cN2.There is clearly a need therefore for a large randomized trial that will resolve the issue either way once and for all.
This study aims to investigate the efficacy and safety of neoadjuvant Toripalimab combined with Nimotuzumab in primary limited stage oral squamous cell carcinoma prior to radical therapy.
The incidence and mortality of esophageal squamous cell carcinoma are at the forefront in China.Most part of patients are elderly. Concurrent chemoradiotherapy is the standard treatment for unresectable locally advanced esophageal squamous cell carcinoma. Most elderly patients cannot tolerate concurrent chemotherapy because of complications and other reasons. Immunotherapy has definite efficacy and low toxicity in advanced esophageal squamous cell carcinoma, and the results combined with radiotherapy have also been preliminarily reported. Therefore, it is necessary to further explore the efficacy and safety of radiotherapy combined with immunotherapy in elderly patients with esophageal squamous cell carcinoma.
The guidelines for locally advanced head and neck squamous cell carcinoma currently recommend surgery / radiotherapy / chemotherapy / targeted therapy. However, the median PFS of patients with high risk factors after comprehensive treatment was about 17 months, and the 2-year PFS rate was about 40 %. The KEYNOTE-048 study showed that PD-1 monoclonal antibody alone or in combination with chemotherapy significantly improved survival and was safe for recurrent / metastatic head and neck squamous cell carcinoma. Therefore, PD-1 monoclonal antibody has become the first-line treatment of metastatic head and neck squamous cell carcinoma. For locally advanced head and neck squamous cell carcinoma, the existing studies on immunotherapy for neoadjuvant or concurrent chemoradiotherapy have not been clearly concluded. We previously used PD-1 monoclonal antibody for the maintenance treatment of patients after the first-line treatment of locally advanced head and neck squamous cell carcinoma, without residual tumor, which showed a trend of prolonged survival. Therefore, this study intends to explore whether the maintenance treatment of PD-1 monoclonal antibody terripril can further improve the survival of patients with locally advanced head and neck squamous cell carcinoma with high risk factors and no residual tumor after first-line comprehensive treatment, and the safety is good.
Rationale: Vulvar squamous cell carcinoma (VSCC) is a rare cancer with a rising incidence. Standard treatment comprises wide local excision of the primary tumour and inguinal lymph nodes and sometimes (chemo) radiotherapy. Treatment is associated with impressive and long-lasting morbidity, sexual and psychological dysfunction and wound healing disorders. Recurrent disease develops in up to 40% of all treated patients. The unmet need, therefore, is a less radical and more effective treatment for VSCC. Hypothesis: Based on the local immune profile in a large fraction of patients with primary VSCC the investigators hypothesize that neoadjuvant PD-1 checkpoint inhibition may reinvigorate tumor-specific T cells resulting in a reduced tumor load, potentially leading to less radical surgery and reduces the recurrence rate. The primary objectives of this trial are to study clinical efficacy and immune activation of neoadjuvant PD-1 blockade in VSCC. Study design: This is a prospective, multicenter phase II non-controlled clinical trial in 40 VSCC patients. Study population: Clinically diagnosed FIGO I-III primary VSCC patients to be treated with surgery with curative intent. Intervention (if applicable): Anti-PD1 antibody pembrolizumab, 200 mg IV Q3W for a total of 2 administrations per patient over a period of 6 weeks prior to surgery. Main study parameters/endpoints: The primary endpoints are: - Clinical efficacy of neoadjuvant PD-1 blockade in VSCC, measured by objective change in tumour size (according to RECIST1.1) - The activation, proliferation and migration of the CD4+CD39+PD-1+ intratumoral T-cell population.
The purpose of this study is to observe and evaluate the correlation between ctDNA-MRD and the therapeutic effect and prognosis of stage II-IVA operable esophageal squamous cell carcinoma.
