Activity and safety of crizotinib in patients with ALK-positive non-small-cell lung cancer: Abstract Crizotinib, the first clinically available inhibitor of anaplastic lymphoma kinase ALK gene rearrangement, is generally well tolerated.

National Center for Biotechnology Information , U. Open in a separate window. Median time to first documented objective response was 7. Pontikoglou C, Papadaki HA. Crizotinib is used worldwide for the treatment of ALK-positive NSCLC; however, there is increasing accumulation of data with regard to its potential adverse events, which may be severe.
Among these, crizotinib was shown to possess marked therapeutic efficacy 3 and was approved by the US Food and Drug Administration FDA inshortly after its development. Estimated median PFS was 8. This article has been cited by other articles in PMC. Patients receiving chemotherapy were permitted to cross over to crizotinib after disease progression as part of the PROFILE study.
Oxford University Press is a department of the University of Oxford. Introduction Non-small-cell lung cancer NSCLC is the most commonly diagnosed type of cancer and is a leading cause of cancer-related mortality worldwide 1.
At 8 weeks, a gradual decrease in neutrophil counts was observed which, by 36 weeks, had progressed to grade 4 neutropenia neutrophil count: Successful treatment of crizotinib-induced dysgeusia by switching to alectinib in ALK-positive non-small cell lung cancer.
In summary, the present case report describes a patient with ALK-positive lung adenocarcinoma who developed severe esophagitis following treatment with crizotinib.
However, ophthalmologic or neurologic evaluation may be necessary for patients whose visual disturbances persist or worsen during treatment.
Please review our privacy xalkor. Patients receiving crizotinib also had a significantly longer time to worsening of lung cancer symptoms cough, dyspnoea or chest pain compared with chemotherapy HR: A Chest computed tomography CT at diagnosis revealed multiple pulmonary nodules in the left upper lobe and a pleural effusion.
Faculty Position – Neuropathologist. Survival benefit of pemetrexed in lung adenocarcinoma patients with anaplastic lymphoma kinase gene rearrangements.
Four months later the CEA levels were within the normal range and a CT examination revealed no evidence of recurrence. Crizotinib was shown to have an acceptable safety profile and also to improve quality of life and symptom scores.

Crizotinib, Anaplastic czse kinase gene rearrangement, Neutropenia, Alectinib, Non-small cell lung cancer. CH, a selective ALK inhibitor capable of blocking the resistant gatekeeper mutant. However, grade 4 neutropenia neutrophil count: In this case report, the details of the clinical course of a patient with severe neutropenia induced by crizotinib are described.
Decisions to withdraw crizotinib should be made on a case-by-case basis. Crizotinib is the first clinically available inhibitor of anaplastic casf kinase ALK gene rearrangement and has shown notable antitumor effects in patients with ALK-positive non-small cell lung cancer NSCLC [ 123 ]. Patients whose tumours express ALK fusion proteins are eligible for treatment with ALK inhibitors, the first of which was crizotinib.

The patient provided their consent for their participation in the study. Crizotinib was also found to result in greater improvements compared with docetaxel for global QoL and all individual domains and compared with pemetrexed for global QoL and physical functioning [ 35 ]. This treatment was continued for 36 months 34 cycles Fig.

Patients should also be educated about signs and symptoms of drug-induced liver injury and hepatic failure [ 34 ]. In this case, the patient exhibited an eminently prolonged response to pemetrexed, which preceded crizotinib treatment. This is illustrated by a recent report of sequential ALK inhibitor therapy that demonstrates the utility of re-biopsy in providing patients with a personalised treatment sequence [ 45 ].
However, information concerning clinical experience and management of severe neutropenia is currently limited. Non-small-cell lung cancer NSCLC is the most commonly diagnosed type of cancer and is a leading cause of cancer-related mortality worldwide.
