چکیده

Patients and methods Fresh tumour samples from 27 CRC patients were used to prepare tumour spheroids. Autologous PBMCs were isolated by ficoll density gradient. Tumour spheroids co-cultured with or without PBMCs were treated with catumaxomab for 96h. The cellular composition of the spheroids and the therapeutic impact on epithelial cells and leukocytes were measured by FACS analysis. The metabolic activity of the co-cultures was determined by the ATP assay.

Clinical Medicine Insights: Therapeutics

The trifunctional, bispecific antibody catumaxomab (anti-EpCAM x anti-CD3) is a new therapeutic strategy for epithelial cancer patients with symptomatic malignant ascites. The trifunctionality has the advantage of binding tumor cells and simultaneously two different immune effector cells (e.g. macrophages and T-lymphocytes). The unique binding specifities of catumaxomab induce an effective dest...

Changing Therapeutic Paradigms: Predicting mCRC Lesion Response to Selective Internal Radionuclide Therapy (SIRT) based on Critical Absorbed Dose Thresholds: A Case Study

A 65 year old male with metastatic colorectal cancer (mCRC) in the liver was referred for selective internal radionuclide therapy (SIRT) following a history of extensive systemic chemotherapy. 90Y PET imaging was performed immediately after treatment and used to confirm lesion targeting and measure individual lesion absorbed doses. Lesion dosimetry was highly predictive of eventual response in ...

AIMS Catumaxomab is the first EMEA approved trifunctional anti-EpCAMxanti-CD3 antibody for the treatment of cancer patients with malignant ascites. A phase II pharmacokinetic study was conducted to determine local and systemic antibody concentrations and anti-drug antibody (ADA) development. METHODS Thirteen cancer patients with symptomatic malignant ascites were treated with four ascending d...

Exploratory analysis of using supervised machine learning in [18F] FDG PET/CT images to predict treatment response in patients with metastatic and recurrent Brest tumors

Aim: Despite grate progress in treatments, breast cancer is still the most common invasive cancer and the most cause of cancer related death in women. Treatment could be improved and perhaps standardized if more reliable markers for tumour progression and poor prognosis could be developed. The aim of this study was to evaluate whether patient-based machine learning (ML) driven ...

Tumour radiobiology beyond fractionation

Historically it has been shown repeatedly that single high doses of radiation do not allow a therapeutic differential between tumor and critical normal tissues but dose fractionation does. The purpose of conventional dose fractionation is to increase dose to the tumor while preserving normal tissue function. Tumors are generally irradiated with 2Gy dose per fraction delivered daily to a more or...
