Active clinical trials for "Extranodal Extension"

Patients with relapsed/refractory diffuse large B cell lymphoma with extranodal (esp. central nervous system) involvement treated with Low-Dose Decitabine plus anti-PD-1 regimen. 3 weeks for a cycle, with a total of 2 years or until the disease progress esor unacceptable toxicity occurs, or the patient decides to withdraw from the trial.

Any patient with a suspected primary adenocarcinoma of the colon, sigmoid or rectum undergoing surgery are eligible. The date of surgery must be known prior to registration. This trial aims to determine if image mapping techniques can improve the concordance between imaging and pathology detection of tumour deposits. Lymph nodes and tumour deposits will be identified on pre-operative scans and mapped by radiologists then shared with pathologists prior to processing the resected specimen. Patients will be managed at their local hospital with standard follow-up. Patients will be followed up for 5 years.

Extranodal extension (ENE) refers to the spread of head and neck squamous cell carcinoma (HNSCC) outside the lymph nodes. It is a well-known factor that indicates a poorer prognosis and outcome for patients who have undergone surgical removal of the cancer. In such cases, it is recommended to combine chemotherapy with radiation therapy after surgery. As the number of cases of HNSCC related to the human papillomavirus (HPV) is increasing, treatment approaches have shifted towards using radiation therapy as the primary treatment method instead of surgery. This raises an important question about the significance of ENE observed through imaging tests (referred to as iENE) and its impact on the prognosis. Unfortunately, this question remains unanswered. The objective of this project is to conduct a comprehensive study across multiple medical institutions. The investigators will gather data including scan results, histopathology reports, and data from patient charts from individuals who have been treated for head and neck cancer. The aim is to analyze and correlate the findings between the pathological evidence of ENE and the imaging results, while also assessing the prognostic value of iENE. Additionally, the investigators will explore the influence of HPV status on these factors. By collecting and analyzing this data, the investigators hope to establish standardized criteria that can assist radiologists in accurately identifying ENE through imaging tests. This research is essential for enhancing our understanding of HNSCC and improving the effectiveness of diagnostic procedures and treatment planning.

This study is a prospective, single center, phase II clinical study involving 108 patients with primary and late stage Diffuse Large B-cell Lymphoma complicated by large masses and extranodal involvement. The study aims to evaluate the efficacy of radiotherapy targeting large masses and extranodal involvement in treatment-naïve advanced DLBCL patients with large mass lesions and/or extranodal involvement after they had initially been treated with standard immunochemotherapy and received complete remission as assessed by PET-CT. After completing the standard immunochemotherapy, subjects will be randomly divided into the radiotherapy group or the non-radiotherapy group, and the curative effects will be evaluated every three months after the end of the treatment or after their leaving the group, so as to obtain the relevant data and data of the 2-year Progression Free Survival, survival of the subjects and Treatment-related side effects.

Development and validation of a model that predicts rENE from radiological imaging using annotated / labeled scans by means of deep learning

Tumor deposits (TDs) are emerging as an adverse prognostic factor in colorectal cancers (CRCs), but they are quite ignored in the current staging system. Previous proposals to incorporate TDs in node stage or consider them distant metastases raised some doubt. The Authors propose a new staging system to optimize treatments.

Tumor deposits (TD), nodules in the peritumoral adipose tissue with no architectural residue of lymph node, which is a definition often being confusing to the extranodal extension (ENE), have been described in several malignancies and linked to a worse prognosis. In gastric cancer and colon cancer, TD and ENE should be distinguished and collected separately in 8th AJCC manual. However, in thyroid cancer, TD as a collection variable was absence in both the 8th AJCC manual and the 2015 ATA guideline. This is a study that revealed the presence of TD by reviewing a large number of papillary thyroid carcinoma (PTC) specimens and explored its prognostic value by constructing a nomogram to accurately predict disease-free survival in PTC patients.
