Does true Gleason pattern 3 merit its cancer descriptor?

Nearly five decades following its conception, the Gleason grading system remains a cornerstone in the prognostication and management of patients with prostate cancer. In the past few years, a debate has been growing whether Gleason score 3 + 3 = 6 prostate cancer is a clinically significant disease. Clinical, molecular and genetic research is addressing the question whether well characterized Gleason score 3 + 3 = 6 disease has the ability to affect the morbidity and quality of life of an individual in whom it is diagnosed. The consequences of treatment of Gleason score 3 + 3 = 6 disease are considerable; few men get through their treatments without sustaining some harm. Further modification of the classification of prostate cancer and dropping the label cancer for Gleason score 3 + 3 = 6 disease might be warranted

Amiloidose localizada laríngea: relato de caso e revisão de literatura Localized laryngeal amyloidosis: case report and literature review

A amiloidose localizada laríngea é uma doença rara, correspondendo a menos de 1% dos tumores benignos da laringe. No entanto, a amiloidose localizada acomete principalmente a laringe nas vias aéreas, sendo assim de grande importância para o otorrinolaringologista. Ela está relacionada à produção monoclonal de imunoglobulinas de cadeia leve, principalmente l e k. Este estudo tem como objetivo relatar um caso de amiloidose laríngea atendida no Ambulatório de Laringologia e Voz do Hospital das Clínicas da FMRP - USP, assim como discutir a revisão de literatura.<br>Localized laryngeal amyloidosis is a rare disease, corresponding to less than 1% of benign tumors in larynx. However, localized amyloidosis occurs mostly in larynx, being of great importance its diagnose by Otorhinolaryngologists. It is related to monoclonal production of light chain immunoglobulins, mainly l and k. This study has the purpose of relating a case of laryngeal amyloidosis assisted in Laryngology and Voice Clinics at Clinics Hospital FMRP - USP, and discussing literature as well
