Novel oncological therapies substantially improved the prognosis of cancer patients. Immunotherapies (immune checkpoint inhibitors) and targeted therapies (tyrosine kinase inhibitors) represent innovative strategies, which have revolutionized cancer patient's approaches. However, the new treatments may bring additional adverse effects, therefore right selection, close monitoring, and appropriate clinical decisions in the event of a complication are of upmost importance in these patients' management. We present an elderly male patient undergoing treatment with alectinib - anaplastic lymphoma kinase (ALK) inhibitor for metastatic non-small cell lung cancer, who was diagnosed with acute liver failure by druginduced liver injury, five months after the start of the therapy. After the other possible causes of hepatocellular injury were excluded, the drug was discontinued. Using corticotherapy and supportive measures, the evolution of the patient was favorable. Up to this moment, data showed that alectinib was less associated with liver function abnormalities compared to other ALK inhibitors, however most commonly of mild or moderate grade of severity, especially in the first two months of treatment. The case we report presented acute onset liver failure, with a relatively late occurrence during alectinib therapy. Timely recognition may improve patients' prognosis, and monitoring must be carried out rigorously. Awareness and effective interdisciplinary communication among medical specialties play a pivotal role in the comprehensive care of cancer patients. [ABSTRACT FROM AUTHOR]

Background & Aims: Real-world assessments of efficacy and safety of advanced therapies used for inflammatory bowel disease (IBD) patients are limited. We aimed to report safety, efficacy and treatment persistence of new molecules (infliximab, adalimumab, vedolizumab, tofacitinib, ustekinumab) in a retrospective multicentric national Romanian analysis. Methods: We conducted a nationwide, retrospective observational multicentric study. Data were collected retrospectively from electronic and paper files. Patients who started on one of the five investigated molecules during December 2019-December 2021 were included. The main outcome measures were clinical remission, endoscopic healing, persistence on treatment and safety data. Results: A total of 678 adult patients from 24 Romanian IBD centers with a diagnosis of ulcerative colitis or Crohn's disease were included. Participants had previously failure to one (268, 39.5%), two (108, 15%) or more treatment lines and only 38% (259) were biologic naïve. In the 24 months study period, most patients were started on vedolizumab (192, 28%), followed by adalimumab, infliximab, ustekinumab and tofacitinib. In biologic-naïve patients, most physicians (72%) preferred anti-TNF treatment as first line biologic (93 patients started on infliximab, 92 on adalimumab), followed by vedolizumab, ustekinumab and tofacitinib. During follow-up, 71% (470, p=0.05) of patients achieved clinical remission and 36% (134, p=0.03) achieved mucosal healing. The 6 months milestone for persistence was reached in 78% (530) of cases. Almost half of patients (47%, 316 patients) persisted on their current treatment for over 12 months. Overall, an adverse reaction was reported for 67 (10.4%) patients, with no lethal events. Conclusions: Population of biologic-experienced IBD patients in Romania is increasing and is becoming more difficult to achieve long-term disease control. Discontinuation rates for advanced therapies are high. [ABSTRACT FROM AUTHOR]
