Combination chemotherapy for head and neck cancer: the addition of Bcl-2 inhibitors

Current Opinion in Investigational Drugs

Abstract

Locoregionally advanced, recurrent and/or metastatic head and neck squamous cell carcinoma (HNSCC) lacks a validated therapeutic approach. Evidence emphasizes the importance of Bcl-2, Bcl-XL and survivin as survival factors in HNSCC cells. Targeting the Bcl-2 system is therefore an attractive strategy for restoring a 'normal' apoptotic process in HNSCC, making cells more susceptible to conventional chemotherapy and disrupting neovascularization. Among Bcl-2 inhibitors, non-peptidic small molecules hold substantial promise in HNSCC adjuvant therapy. Predicting treatment response requires the precise profiling of tumors, ideally by the use of panels that include markers from different pathways; the further definition of such panels may benefit from proteomic and/or pharmacogenomic approaches. Furthermore, in combination treatments, the effect of drug delivery sequence requires further investigation.

BCL-2 Family Proteins

BLC-2 family proteins are a group that share the same homologous BH domain. They play many different roles including pro-survival signals, mitochondria-mediated apoptosis and removal or damaged cells. They are often regulated by phosphorylation, affecting their catalytic activity. Here is the latest research on BCL-2 family proteins.

Apoptosis

Apoptosis is a specific process that leads to programmed cell death through the activation of an evolutionary conserved intracellular pathway leading to pathognomic cellular changes distinct from cellular necrosis

Apoptosis in Cancer

Apoptosis is an important mechanism in cancer. By evading apoptosis, tumors can continue to grow without regulation and metastasize systemically. Many therapies are evaluating the use of pro-apoptotic activation to eliminate cancer growth. Here is the latest research on apoptosis in cancer.

Carcinoma, Squamous Cell

Basal cell carcinoma is a form of malignant skin cancer found on the head and neck regions and has low rates of metastasis. Discover the latest research on basal cell carcinoma here.
