Dasatinib is a tyrosine kinase inhibitor used for treatment of some specific types of leukaemia. The development of pleural effusion is a known adverse effect of dasatinib and chylothorax is exceptional. No case has been reported beyond 5 years of treatment and extensive search for an alternative diagnosis is currently suggested in such scenario. The underlying mechanism is not currently clear. We describe a woman on dasatinib treatment for more than 10 years who developed chylothorax. Drug withdrawal resolved the chylous pleural effusion. We were able to find 14 additional cases of dasatinib-related chylothorax reported up until now.

This report describes a rare case of oligometastatic renal disease in a 69 year-old Caucasian male with non-small cell lung cancer (NSCLC). Diagnosed with Stage IIIb, NSCLC he completed chemoradiotherapy followed by 1 year of immunotherapy. Surveillance CT scans after nearly three years showed an ill-defined lesion in the left kidney.
Biopsy results were consistent with metastasis from the known lung carcinoma. Following neo-adjuvant Pembrolizumab (200mg, q3w), the patient underwent a left radical nephrectomy, without complications. One year post-operatively, CT of the thorax, abdomen and pelvis (TAP) did not identify any recurrence.
Renal metastases were historically demonstrated predominantly by autopsy studies[1]. Any mass manifesting in the kidney in the context of previous NSCLC warrants comprehensive investigations. The combination of immunotherapy followed by definitive treatment appears to be a promising management strategy[2]. With regards to local curative options, the advantages and disadvantages of surgery and radiotherapy have been well described[3-4].
