Treatment with analogues of the SERCA-inhibitor Thapsigargin is a promising new approach for a wide variety of cancer entities. However, our previous studies on various tumor cells suggested resistance of SEC62 over-expressing tumors to this treatment. Therefore, we proposed the novel concept that e.g. lung-, prostate-, and thyroid-cancer patients should be tested for SEC62 over-expression, and developed a novel therapeutic strategy for a combinatorial treatment of SEC62 over-expressing tumors. The latter was based on the observations that treatment of SEC62 over-expressing tumor cells with SEC62-targeting siRNAs showed less resistance to Thapsigargin as well as a reduction in migratory potential and that the siRNA effects can be mimicked by the Calmodulin antagonist Trifluoperazine...

Elective neck dissection of the N0-neck is routinely performed during salvage laryngectomy (SLE) for recurrent cancer of the larynx or hypopharynx. The therapeutic benefit of additional neck dissection must be weighed against the risk of increased morbidity. In this retrospective analysis, we assessed oncologic parameters of patients who underwent SLE with concurrent bilateral neck dissection for recurrent laryngeal or hypopharyngeal cancer. We compared these data with patients who underwent primary laryngectomy (LE) with bilateral neck dissection for laryngeal and hypopharyngeal cancer...

BACKGROUND: Defects after total pharyngolaryngectomy for hypopharyngeal cancer often require reconstruction via free tissue transfer. Recently, anterolateral thigh (ALT) flap has become the gold standard in many centers because of its advantages with respect to versatility, minimal donor-site morbidity, good speech quality, and relatively low fistula and anastomotic leakage rates. Moreover, ALT allows 2 surgical teams to work simultaneously. However, the height of the parallelogram in the ALT design for neoesophagus reconstruction is usually set at a minimum of 9...

PURPOSE: The pectoralis major musculocutaneous (PMMC) flap is a classic flap for head and neck reconstruction, relatively unpopular with the advancement of microsurgery and free flaps. The classic parasternal paddle design provided a thick flap with a small rotation arch leaving objectionable scarring. Our new symmetric midsternal design overcomes these problems. METHODS: Chart review was done from the years 2000 to 2017. Flap skin paddle was placed symmetrically on both sides of the midsternal line...

NVP-BEZ235 is a dual phosphoinositide 3-kinase (PI3K)-mammalian target of rapamycin (mTOR) inhibitor. A dual approach targeting more than one downstream effector is a promising strategy for treating cancers. The aim of this study was to evaluate the effect of NVP-BEZ235 in treating FaDu hypopharyngeal squamous cell carcinoma (HSCC), either alone or in combination with cisplatin. We found mTOR expression was higher in patients with HSCC. In the in vitro study, treatment with NVP-BEZ235 alone attenuated cell proliferation and suppressed p-p70S6K and p-4E-BP1 expression in FaDu cells...

Programmed death ligand-1 (PD-L1) immunohistochemistry is used to guide treatment decisions regarding the use of checkpoint immunotherapy in the management of urothelial carcinoma of the bladder and hypopharyngeal (HP) squamous cell carcinoma. With increasing PD-L1 testing options, a need has arisen to assess the analytical comparability of diagnostic assays in order to develop a more sustainable testing strategy. Using tissue microarrays, PD-L1 expression in tumor cells (TCs) and immune cells (ICs) was manually scored in 197 cases and 27 cases of bladder and HP cancer, respectively...

Hypopharyngeal carcinoma (HC) is one of the most malignant tumors in the upper aerodigestive tract. Currently, there are no effective treatments for HC. Gold nanoparticles (AuNPs) are a promising tool that can be used for plasmonic photothermal therapy (PPTT), which refers to the use of electromagnetic radiation, most often in near infrared (NIR) region, for the treatment of various medical conditions including cancer. AuNPs have been proved to be a promising tool for NIR spectroscopy-mediated photothermal therapies...
