Since the introduction of Pap smear screening, the incidence and mortality of cervical cancer (CC) have been reduced drastically in USA and in other western states. Nevertheless, CC still remains the main cause of death from gynecological cancer in developing countries where screening programs are scant or inexistent. This evidence highlights the efficacy of screening, and the wide use of Human Papilloma Viruses (HPV) vaccines in developed countries. More and more people are, consequentially, undergoing a screening procedure, usually combined with HPV DNA test, increasing the early diagnosis of intraepithelial HPV-related lesions...

Antibody-drug conjugates (ADCs) developed using the valine-citrulline-MMAE (vc-MMAE) platform, consist of a monoclonal antibody (mAb) covalently bound with a potent anti-mitotic toxin (MMAE) through a protease-labile vc linker. Recently, clinical data for a variety of vc-MMAE ADCs has become available. The goal of this analysis was to develop a platform model that simultaneously described antibody-conjugated MMAE (acMMAE) pharmacokinetic (PK) data from eight vc-MMAE ADCs, against different targets and tumor indications; and to assess differences and similarities of model parameters and model predictions, between different compounds...

REVIEW
Rupert Langer, Karen Becker
Neoadjuvant therapy has been successfully introduced in the treatment of locally advanced gastrointestinal malignancies, particularly esophageal, gastric, and rectal cancers. The effects of preoperative chemo- or radiochemotherapy can be determined by histopathological investigation of the resection specimen following this treatment. Frequent histological findings after neoadjuvant therapy include various amounts of residual tumor, inflammation, resorptive changes with infiltrates of foamy histiocytes, foreign body reactions, and scarry fibrosis...

Craniopharyngiomas are histologically benign but locally aggressive tumors in the sellar region that may cause devastating neurological and endocrine deficits. They tend to recur following surgery with high morbidity; hence, postoperative radiotherapy is recommended following sub-total resection. BRAFV600E mutation is the principal oncogenic driver in the papillary variant of craniopharyngiomas. Recently, a dramatic tumor reduction has been reported in a patient with BRAFV600E mutated, multiply recurrent papillary craniopharyngioma using a combination therapy of BRAF inhibitor dabrafenib and MEK inhibitor trametinib...

Notch signaling pathway is evolutionarily conserved in mammals, which plays an important role in cell development and differentiation. In recent years, increasing evidence has shown that aberrant activation of Notch is associated with tumor process. Aberrant activation of Notch signaling pathway has been found in many different solid tumors can induce cell proliferation, metastasis and epithelial-mesenchymal transition. Notch receptor and its ligand are both single transmembrane protein, and Notch is activated when it binds to the Notch ligand of neighbor cells...

Strategies that induce immunogenic cell death (ICD) or downregulate CD47 or PD-L1 expression have resulted in successful therapeutic options for tumor eradication. Several groups have reported the tumoricidal effects of human umbilical cord Wharton's jelly stem cells (hWJSCs) or its conditioned medium (hWJSC-CM) on certain cancers but the mechanisms have not been elucidated. Since hWJSCs possess immunomodulatory properties, we investigated whether one of the tumoricidal mechanisms was via ICD. We first concentrated hWJSC-CM into a 3 kDa concentrate and then exposed various concentrations of this concentrate to human lymphoma cells to find out which concentration had the greatest tumoricidal effect...

REVIEW

Pre-emptive transplantation is a well-established practice for certain types of end-organ failure such as in the use of kidney transplantation. For irreversible intestinal failure, total parenteral nutrition (TPN) remains the gold standard, due to the suboptimal long-term results of intestinal transplantation. As such, the only role for pre-emptive transplantation, if at all, will be for patients identified to be at high risk of complications and mortality while on definitive long-term TPN. In these patients, the timing of early listing and transplantation could become life-saving, taking into account that mortality on the waiting list is still the highest for intestinal candidates...
