Filter by:To clarify the effect of Two-field or Three-field Lymphadenectomy on the survival of esophageal squamous cell carcinoma.
To determine whether older patients who underwent esophagectomy had better outcome survival than those who were non-surgically treated.
Neoadjuvant chemoradiotherapy (CRT) followed by surgery or definitive CRT is the standard treatment for locally advanced esophageal squamous cell carcinoma (ESCC), but the clinical outcomes are not satisfactory. Breathomics testing is a promising, non-invasive, simple method for detection and screening for ESCC. This observational study aimed to role of exhaled volatile organic compounds (VOCs) in predicting the efficacy and risk of recurrence in patients with locally advanced ESCC who received CRT.
The primary objective is to describe the real-world clinical effectiveness of cemiplimab in patients with locally advanced cutaneous squamous cell carcinoma (laCSCC) or metastatic cutaneous squamous cell carcinoma (mCSCC) treated in routine clinical practice.
The treatment guideline for locally advanced resectable oral squamous cell carcinoma (LAROSCC) is surgery + postoperative radiotherapy/chemoradiotherapy. Though the treatment is intensive with serious harm to quality of life, the survival of patients is poor. Neoadjuvant therapy has been evaluated in a number of clinical trials for LAROSCC, but failed to directly improve the overall survival. On the other hand, de-escalation of treatment followed by neoadjuvant is also been explored with some promising results. This study is to retrospectively include patients with LAROSCC who received neoadjuvant therapy and surgery. Survival between patients in two cohorts (cohort 1: received postoperative radiotherapy, cohort 2: received no postoperative radiotherapy) are to be compared.
Primary Objective: -Assess the effectiveness of cemiplimab versus other available systemic therapies in patients up to 2018 or say historical system organ class (SOC) with metastatic or locally advanced cutaneous Squamous Cell Carcinoma (CSCC) who are not candidates for curative surgery or curative radiation, on overall survival (OS). Secondary Objectives: - Assess Progression Free Survival (PFS) - To assess Duration of Response (DOR) - To assess Objective Response Rate (ORR) - To describe adverse events leading to treatment interruptions and deaths
This is a study to evaluate the efficacy and safety of neoadjuvant pembrolizumab plus chemotherapy in resectable locally advanced esophageal squamous cell carcinoma patients
Head and neck cancer (HNC) continues to be a significant health care problem in Taiwan and oropharyngeal squamous cell carcinoma (SCC) is the common subtype. With the concern of organ preservation in recent years, concurrent chemoradiation is the major treatment modality for oropharyngeal SCC, while endoscopy with biopsy serves as the main diagnostic tools. With the advance of MRI technology, whole body MRI is now possible, and functional techniques become more feasible in the head and neck region, including diffusion-weighted imaging (DWI) which comprises of monoexponential DWI, intravoxel incoherent motion (IVIM) model and Kurtosis (biexponential or non-Gaussian fitting), and dynamic contrast-enhanced perfusion weighted MRI (DCE-PWI) become feasible. Therefore, MRI can evaluate distant site status of HNC in the single examination session and provide biologic information of tumors. Positron emission tomography/CT (PET/CT) is another common imaging modality to evaluate HNC, because of its ability to provide whole-body anatomic and metabolic information. Integrated PET/MRI is a novel imaging technology that combines PET and MRI in one single scanner. In this 3-year prospective study, the investigators will take the advantages of integrated PET/MRI scanner with DWI (including monoexponential, kurtosis and IVIM modes) and DCE-PWI to evaluate our 160 patients with oropharyngeal SCC subjected to chemoradiation. Non-contrast chest CT will also be performed on the same day. The investigators aim to determine whole-body staging/restaging accurately, to predict treatment response and prognosis, and to determine necessity of noncontrast chest CT. The investigators expect that this project will offer the validation of usefulness of integrated PET/MRI in tumor staging/restaging of oropharyngeal SCC and resultant clinical impact. The role of noncontrast chest CT in the workup with our PET/MRI protocol can be defined. It will also provide evidence about how and to what extent the various simultaneously acquired MRI and PET functional parameters can help prediction of treatment response and prognosis of oropharyngeal SCC subjected to chemoradiation, which are important in timely modification of treatment regimen.
Squamous cell carcinoma of the anal canal is a rare cancer with an increasing incidence. It represents 2.5% of digestive cancers and occurs more frequently in immunocompromised persons, in particular HIV positive. It is a cancer that develops essentially locally, with only 5% of metastases at diagnosis. The reference treatment for forms deemed localized after clinico-bio-radiological pre-therapeutic evaluation is radiochemotherapy allowing a 5-year survival rate of about 80%. However, up to 30% of patients fail radiochemotherapy. Failure is defined as persistent disease (non response or progression in 10 to 15% of patients) or relapse (local or metastatic in 10 to 15% of patients). Salvage surgery by abdominoperineal amputation is indicated in this case after elimination of the metastatic character with an overall survival rate at 5 years varying from 23 to 69%. This complex and cumbersome surgery is burdened with significant postoperative morbidity with alteration of the quality of life. Investigators would like to perform a retrospective and prospective study in the Paris Saint-Joseph hospital group to evaluate the interest of abdominoperineal amputation in case of failure of radiochemotherapy in patients with squamous cell carcinoma of the anal canal.
This study determines whether a positron emission tomography (PET)/computed tomography (CT) 4-point scoring system may predict overall survival for anal squamous cell cancer patients. A 4-point scoring system involving imaging scans may help to predict how patients with anal squamous cell cancer respond to chemoradiation therapy.
