Co-targeting PI3K/Akt and MAPK/ERK pathways leads to an enhanced antitumor effect on human hypopharyngeal squamous cell carcinoma

ConclusionDual inhibition of PI3K/Akt and MAPK/ERK pathway by GDC-0980 and Refametinib might be a promising treatment  strategy for HSCC patients.

ConclusionIn summary, our deactivation model of MALAT1 disentangled the active function of it as a regulator of gene expression governing the hallmarks of laryngeal and hypopharyngeal cancer. Blocking this long non-coding RNA may restrain the development of laryngeal cancer.

In this study, we found that 3-phosphoinositide-dependent protein kinase 1 (PDK1 or PDPK1) was overexpressed in HSCC. The overexpression was positively correlated lymph node metastasis, clinical stage, and distant metastasis and indicated poor outcome. Loss and gain-of-function revealed that PDK1 increased cell proliferation, migration and invasion in vitro as well as tumor growth and metastasis in vivo. Mechanically, PDK1 induced epithelial-mesenchymal transition and promoted metastasis by activating the Notch1 signaling pathway. We further illustrated that PDK1 bound with the Notch1 intracellular domain, thereby inhibiti...

This study aimed to test the role of Cx43 protein on Bcl-2 expression, tumor progression and response to taxane-based treatment in HNSCC. Human papillomavirus (HPV) negative HNSCC cell lines were tested for paclitaxel sensitivity through measuring apoptosis induction, cell viability and changes in Cx43 and Bcl-2 levels using flow cytometry, cell viability assay, immunocytochemistry and western blot. Inhibition of Cx43 expression using siRNA increased Bcl-2 protein levels in SCC25 (tongue squamous cell carcinoma) cells, while forced Cx43 expression reduced Bcl-2 levels and supported paclitaxel cytotoxicity in FaDu (hypophar...

We examined 198 consecutive patients with biopsy-proven OHSCC who agreed to receive chemoradiation. All patients underwent pretreatment PET/MRI and PET/CT on the same day. Patients were followed-up for a minimum of 12  months or until death. The McNemar’s test and receiver-operating characteristic (ROC) curves were used to compare sensitivity/specificity and the diagnostic capabilities of PET/MRI, MRI, and PET/CT, respectively.ResultsWe identified 55 patients (27.7%) who had synchronous cancers and/or distant metastases (number of involved sites: 83). The results of site-based analysis revealed that the sensitiv...

ConclusionsA single-cycle induction chemotherapy for HNSCC enables surgery plus adjuvant therapy as well as chemoradiotherapy. The long-term local and distant disease control was good but varied between tumors in the larynx and mesopharynx/tongue vs. hypopharynx.

CONCLUSION: This study suggests that duration of adjuvant therapy may be more important than other timing metrics from diagnosis to treatment. For locoregionally advanced HSCC, duration of adjuvant therapy after primary surgery higher than 6 weeks is an important feature for worse survival outcome. Preventing strategies in order to avoid radiotherapy or chemoradiotherapy breaks should be developed and optimized. PMID: 31569981 [PubMed - as supplied by publisher]
