Patient derived xenografts (PDX) are models of cancer where the tissue or cells from a patient's tumor are implanted into an immunodeficient or humanized mouse. [1] It is a form of xenotransplantation .
Xenotransplantation of human tumor cells into immunocompromised mice is a research technique frequently used in oncology research. [45] It is used to predict the sensitivity of the transplanted tumor to various cancer treatments; several companies offer this service, including the Jackson Laboratory. [46]
In 1987, the UICC and AJCC staging systems were unified into the single TNM staging system. TNM is a notation system that describes the stage of a cancer, which originates from a solid tumor, using alphanumeric codes: T describes the size of the original (primary) tumor and whether it has invaded nearby tissue,

Congenital epulis, also known as congenital granular cell tumour is a benign rare tumour of the oral cavity of newborn infants.The initial first description of the lesion was dated in 1871 by Dr. Franz Ernst Christian Neumann, who coined the name for the tumour, known as Neumann’s tumour.
Doctor reviewing a radiation treatment plan. In radiotherapy, radiation treatment planning (RTP) is the process in which a team consisting of radiation oncologists, radiation therapist, medical physicists and medical dosimetrists plan the appropriate external beam radiotherapy or internal brachytherapy treatment technique for a patient with cancer.
Proliferation, as one of the hallmarks and most fundamental biological processes in tumors, [1] is associated with tumor progression, response to therapy, and cancer patient survival. [2] Consequently, the evaluation of a tumor proliferative index (or growth fraction) has clinical significance in characterizing many solid tumors and hematologic ...
(The one-year survival rate has been estimated to be roughly 60%, although this figure includes deaths from the underlying disease, as well as from the transplant procedure.) [51] Major complications include veno-occlusive disease, mucositis, infections , graft-versus-host disease, and the development of new malignancies.
