CARCINOMA GLOTTIS WITH PAROTID METASTASIS

Carcinoma glottis with parotid metastasis

Introduction: Glottic carcinomas represent approximately one third of the laryngeal cancers.True glottis includes both true vocal cords including anterior and posterior commissures.True vocal cord are as such devoid of lymphatics, so the chances of lymph node metastasis as such is very low.The chances of distant metastasis is also very rare.Herein

A note on computing average state occupation times

Objective: This review discusses how biometricians would probably compute or estimate expected waiting times, if they had the data.Methods: Our framework is a time-inhomogeneous Markov multistate model, where all transition hazards are allowed to be time-varying.We assume that the cumulative transition hazards are given.That is, they mpu63zm/a are
