Secondary spontaneous pneumothorax during chemotherapy with bevacizumab for cervical cancer: a case report and literature review.

Secondary spontaneous pneumothorax (SSP) due to bevacizumab has been reported in other malignancies but not in cervical cancer. We present the case of a 57-year-old woman with stage IIIB cervical cancer who developed SSP during bevacizumab chemotherapy. Despite complete remission with cisplatin-based chemoradiotherapy, she experienced a recurrence 9 months later. A thoracoscopic surgery was performed to remove a lung nodule and bulla. Subsequently, local cervical lesion recurrence and lung metastases were noted, and paclitaxel and carboplatin combined with bevacizumab were administered. After two cycles, a grade-1 left pneumothorax occurred, attributed to bevacizumab-induced tissue fragility. The patient improved within 7 days with conservative management. Bevacizumab was discontinued, and pneumothorax did not recur. This case highlights the rare occurrence of SSP in patients with cervical cancer treated with bevacizumab and underscores the importance of appropriate management of such patients, especially those who have undergone early thoracic surgery.
