The introduction of biologic drugs represents the most significant advance in the management of immune-mediated inflammatory diseases for a decade. However, complex proteins are expensive to produce and manufacture. Biosimilar versions of established biologics are becoming available as another version of the reference medicinal product and are expected to provide substantial cost savings. However, because of their complexity, the approval of biosimilars requires strict controls to ensure that all therapeutically relevant characteristics are comparable to the reference medicinal product. This review summarizes the scientific principles and data requirements underpinning regulatory approval of biosimilars and the assumptions that enable extrapolation of data between indications. These important concepts are exemplified by CT-P13 (Remsima(®), Inflectra(®)), the first biosimilar monoclonal antibody approved in Europe.

Rationale: Locked-in syndrome (and its variant, completely locked-in state) generally has a high mortality rate in the acute setting; however, when induced by conditions such as acute inflammatory polyradiculoneuropathy, it may well be curable such that an attempt at cure should be systematically sought by clinicians.
Patient Concerns: A 52-year-old man presented with acute tetraparesia and areflexia, initially diagnosed as Guillain-Barré syndrome. Despite appropriate treatment, his condition deteriorated, evolving into a completely locked-in state.

We present the case of a 60-year-old man admitted to the hospital presenting with high FUO (fever of unknown origin), strong headache, face erythematous-desquamative cutaneous lesions, long history of abdominal pain, and diffuse myalgia. He was also previously treated with immunosuppressants and currently managed with corticosteroids for a seronegative rheumatic disease. Given the immunocompromised state, an infective etiology was suspected.

A 57-year-old man with a 3-month history of lower abdominal pain and rectal bleeding with black stools underwent urgent abdominal CT, which revealed an ovoid hyperdense lesion in the ileum in the right iliac fossa. The prime differential was a midgut neuroendocrine tumor. Thus, the patient was referred for a 68Ga-DOTATATE PET/CT scan, which demonstrated intense activity in this lesion with no evidence of somatostatin receptor expression elsewhere.

Purpose: Establishing an accurate prognosis remains challenging in older patients with cancer because of the population's heterogeneity and the current predictive models' reduced ability to capture the complex interactions between oncologic and geriatric predictors. We aim to develop and externally validate a new predictive score (the Geriatric Cancer Scoring System [GCSS]) to refine individualized prognosis for older patients with cancer during the first year after a geriatric assessment (GA).
Materials And Methods: Data were collected from two French prospective multicenter cohorts of patients with cancer 70 years and older, referred for GA: ELCAPA (training set January 2007-March 2016) and ONCODAGE (validation set August 2008-March 2010).

The world population is aging. Comprehensive Geriatric assessment (CGA) has been proven to improve the well-being of older adults. However, evidence suggests not all clinicians implement these recommendations in their practice; nor do all patients adhere to them.
