Role of Bispecific Antibodies in Gastroenteropancreatic Neuroendocrine Neoplasms (GEP-NENs): Review of Literature.

Gastroenteropancreatic neuroendocrine neoplasms (GEP-NENs) are a heterogeneous group of neoplasms with an increasing incidence in the last few decades. Despite therapeutic advances in the management of GEP-NENs, resistance to many of these treatments has made their management a great challenge. One of the most recent advances in oncologic therapy is targeting multiple receptors simultaneously and engaging immune cells in the tumor microenvironment through bispecific antibodies (BsAbs).

Induction chemotherapy with capecitabine and oxaliplatin followed by chemoradiotherapy before surgery in patients with locally advanced rectal cancer.

Background: Locally advanced rectal cancer (LARC) has a high incidence of local and distant relapse even after adequate treatment. The emerging role of neoadjuvant induction chemotherapy may allow initial down staging of the primary tumor, less toxicity and early treatment of micrometastatic disease followed by chemoradiation with the hope of increased complete response rates before surgery OBJECTIVES: To identify the effect of induction chemotherapy before concurrent chemoradiation (CCRTH) in locally advanced rectal cancer in terms of response and toxicity. Primary end point is assessment of pathological complete response rate after surgery.
