[Organ preservation in advanced laryngeal/hypopharyngeal carcinoma: lessons from the DeLOS-II trial].

HNO 2020 May 28. Epub 2020 May 28.

Klinik für Hals-Nasen-Ohren-Heilkunde, Universitätsmedizin Leipzig, Liebigstraße 10, 04103, Leipzig, Deutschland.

Patients with locoregionally advanced laryngeal and hypopharyngeal squamous cell carcinomas (LHSCC) comprise two broad groups: those who are candidates for functional larynx preservation (LP) with avoidance of ablative surgery and those who are not. Currently, treatment depends on the patient's needs and wishes, the experience and recommendation of the surgeon, the philosophy of the institution, etc. The milestone VA trial established non-surgical LP in advanced LHSCC in the 1990s using induction chemotherapy (IC) with PF (cisplatin, P, plus 5‑fluorouracil, F) followed by irradiation (IC + RT) as an appropriate alternative treatment to total laryngectomy (TL).

Selective EP2 and Cox-2 inhibition suppresses cell migration by reversing epithelial-to-mesenchymal transition and Cox-2 overexpression and E-cadherin downregulation are implicated in neck metastasis of hypopharyngeal cancer.

Am J Transl Res 2020 15;12(3):1096-1113. Epub 2020 Mar 15.

Department of Otorhinolaryngology-Head and Neck Surgery, Keio University School of Medicine Tokyo, Japan.

Cyclooxygenase-2 (Cox-2) has been shown to promote cancer initiation and progression through pleiotropic functions including induction of epithelial-to-mesenchymal transition (EMT) via its predominant product prostaglandin E that binds to the cognate receptor EP2. Hence, pharmacological inhibition at the level of EP2 is assumed to be a more selective alternative with less risk to Cox-2 inhibition. However, little is known regarding the anti-cancer effect of an EP2 antagonist on the malignant properties of cancers including hypopharyngeal squamous cell carcinoma (HPSCC). Read More
