Recurrent pneumothorax in a patient with liposarcoma as either a complication of lung micrometastasis or a potential adverse event from antibiotic therapy: A case report
Abstract
Spontaneous pneumothorax (PNX) is an infrequent manifestation of primary lung cancer, soft tissue sarcoma and metastasis. There are no easily accessible data in the literature regarding the correlation between PNX and antibiotics, whereas cases of PNX following chemotherapy have been observed. Only 1-10% of treatment-related adverse events are estimated to be reported to the Food and Drug Administration. The present study described a case of PNX of the left lung in a 70-year-old treatment-naive patient with retroperitoneal liposarcoma. The PNX developed after 8 days of treatment with levofloxacin and after 6 days of piperacillin/tazobactam treatment for a suspicious inflammatory area in the right lung detected by an FDG-PET scan before the patient started chemotherapy. A chest CT scan confirmed the presence of metastasis in the right lung, but neither FDG-PET/CT nor CT showed metastatic disease in the left lung. A total of 14 days after the end of the third cycle of doxorubicin (2 months after the initial diagnosis of PNX), the patient manifested a massive PNX of the right lung. In conclusion, these findings indicated that spontaneous PNX could be linked to the use of some antibiotics.
How strong is the evidence?
Evidence Hub reads this as a case report, done in people. Its evidence level is 5 of 5 (Very low · case / narrative / animal / in vitro / in silico). Case reports, narrative reviews, and animal, cell or computer-model studies give the weakest evidence for human health.
