Active clinical trials for "Carcinoma, Squamous Cell"

This is a Phase 2, multicenter, open-label, 2-cohort (Locoregionally Advanced Cohort or Recurrent/Metastatic Cohort) study evaluating RP3 in combination with concurrent chemoradiation therapy (CCRT) followed by nivolumab (for the LA Cohort) or combined with chemotherapy and nivolumab (for the R/M Cohort) in patients with advanced, inoperable squamous cell carcinomas of the head and neck (SCCHN), including of the oral cavity, oropharynx, hypopharynx, larynx, or unknown primary.

This is an observational prospective bi-center study of 50 patients operated on advanced squamous cell carcinoma. The main aim is to investigate the efficacy of serum exosomal miRNA as a biomarker for predicting the therapeutic effect of immunotherapy combined with chemotherapy.

The goal of this observational study is to explore whether ctDNA dynamic monitoring plus AI-based pathology can more effectively predict the therapeutic effect of neoadjuvant chemoimmunotherapy for resectable lung squamous cell carcinoma, so as to accurately guide clinical diagnosis and treatment.

Multi-center, open-label, non-randomized, non-comparative two-cohort study for patients with locally-advanced squamous cell carcinoma arising from the larynx, hypopharynx, oropharynx (Stage III, IVA and IVB according to 8th TNM/AJCC ed.) and oral cavity (unresectable, stage IVB according to 8th TNM/ American Joint Committee on Cancer (AJCC) ed.) who are candidates for definitive radiotherapy plus cisplatin (Cohort A) or as single-modality (in cisplatin unfit patient population) (Cohort B) and will receive dostarlimab and niraparib in combination pre-, during and post- radiation. Study has three parts: Neoadjuvant phase (immune-conditioning phase): patients will receive 1 dose of dostarlimab + niraparib from day -14 prior to radiotherapy (up to 48h prior to radiotherapy (RT) in Cohort A and until RT in Cohort B). Concurrent phase (radiosensitization): patients will receive definitive radiotherapy (70Gy in 35 fractions) with concurrent cisplatin (Cohort A) or with concurrent niraparib (Cohort B). Maintenance: Following radiotherapy, patients will receive adjuvant dostarlimab plus niraparib until week 48 (37 cycles) in both cohorts.

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 is a 20 patient pilot study to examine the feasibility of dose-adapted radiation therapy for the treatment of locally advanced anal squamous cell cancer. The tumor and a patient's anatomy may change during radiation treatment and daily adaption of the radiation plan (i.e., a new daily plan based on the anatomy of the day) may help to maximize the dose to the tumor and minimize the radiation dose to the normal surrounding organs.

Patients with locally recurrent squamous-cell carcinoma of the head and neck (SCCHN) after Chemotherapy and immunotherapy have a very poor prognosis and limited therapeutic options. Intratumoral chemotherapy (ITC) with cisplatin and epinephrine in order to increase the local cisplatin retention lead to a 50 % response rate in several studies but was given up due to the poor local tolerance with frequent necrosis of the peritumoral tissues. Gemcitabine, carboplatin and paclitaxel (GCP) are used in advanced SCCHN. These chemotherapies seem to be interesting options for intratumoral infusion: their different effect could lead to avoid chemotherapy resistance with a good tolerance profile, without tissue necrosis profile. The other major option for recurrent SCCHN is immunotherapy by Nivolumab, an anti PD-1 with a 13% mediane response rate. Nevertheless, the failure of this treatment stay unclear, but immunosuppressive action of the tumour is suspected. The presence of tumoral antigen could lead to better response to immunotherapy; association of chemotherapy and immunotherapy seems a promosing association to avoid treatment resistance as cytotoxic release tumoral antigen; it could also be associated to an abscopal effect. The aim of the study is to evaluate the efficacy of ITC using GCP in LOCAL recurrent SCCHN treated by nivolumab.

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.

This is a first-in-human phase I/II study to examine the safety, tolerability and preliminary efficacy of VLS-1488 in subjects with advanced cancers.

To evaluate the predictive value and mechanism of inflammatory factors in peripheral blood on the prognosis of patients, and to explore the influencing factors of inflammation and tumor microenvironment on the efficacy of neoadjuvant chemotherapy combined with immunotherapy for esophageal cancer. To explore the predictors of neoadjuvant therapy in patients with esophageal squamous cell carcinoma.
