Establishment of Squamous Cell Organoids of the Head and Neck to Assess Their Response to Innovative Therapies

Recruiting now

Conditions studied: Head and Neck Cancer

In brief

The emergence of tumor organoid cultures in recent years has made it possible to widen the repertoire of available preclinical tumor models and to bridge the gap between cell lines and tumors of xenografted patients in mice (PDXs).These organoids have the advantages of being able to be amplified fairly quickly after resection of the tumor, of having unlimited proliferation potential, a high rate of establishment success, and the possibility of being transfected and cryopreserved. These characteristics therefore allow them to summarize the clinical spectra of cancers, but also to be models for studying tumor progression as has been done with organoids for colorectal cancer. They are also very close morphologically and genetically to the tumor from which they derive.Finally, clinical trials are underway to determine whether the organoids of mammary, pulmonary and colorectal cancers can predict the response to patients' treatments and guide the therapeutic decision.It would therefore be possible to test multiple treatments on different samples. This would allow screening of a panel of treatments on a given tumor type but also to test a treatment ex vivo before administering it to the patient in vivo. This prospect is very interesting in particular in the tumors of the VADS where more than two thirds of the operated patients will benefit from a complementary treatment by radiotherapy and / or chemotherapy whose consequences can be important. Despite this adjuvant management, up to 30% of patients will relapse, highlighting a variable tumor chemosensitivity. This screening could make it possible to refine the choice of treatments adapted to each patient and thus limit the undesirable effects.The feasibility of establishing head and neck squamous cell organoid lines seems encouraging, with organoids derived from squamous cell carcinoma of the oral cavity and oropharynx having been recently established.
