Bevacizumab treatment for advanced non-small cell lung cancer: A case report

چکیده
The safety of Avastin in lung cancer (SAiL) study is a multi-center, open-source, stand-alone study. Patients with untreated, locally advanced, metastatic or recurrent non-squamous non-small cell lung cancer (NSCLC) were administered up to six cycles of chemotherapy combined with bevacizumab-humanized monoclonal antibodies, followed by maintenance therapy with bevacizumab until further progression of the disease. From August, 2006 to July, 2008 there were a total of 2,172 patients enrolled in the study, with a median progression-free survival time of 7.8 months and an overall survival time of 14.6 months. The present study describes the case of a 54-year-old male with lung cancer and T3N0M1 subcutaneous metastasis, which was initially treated with bevacizumab-combined carboplatin/paclitaxel (C/P) therapy and then maintained solely with bevacizumab for five years. Following six cycles of C/P bevacizumab treatment, the therapeutic evaluation revealed a stable disease (SD). The patient was kept on bevacizumab maintenance therapy for 50 months without disease progression until a persistent 3+ proteinuria was diagnosed in a follow-up review, which led to bevacizumab withdrawal and concomitant tumor growth. The present study concluded that the long-term application of bevacizumab monoclonal antibodies (mABs) was safe in a late-stage non-small cell lung cancer patient. The major adverse reaction that was exhibited was proteinuria, which was associated with the cumulative dose of bevacizumab and was able to be reversed by withdrawal. Patients with a prolonged SD may benefit from bevacizumab maintenance therapy.

Connective tissue diseases, including scleroderma, may be associated with an increased risk of lung cancer. The most common type of lung cancer associated with systemic sclerosis is adenocarcinoma or bronchoalveolar carcinoma, and small cell carcinoma is rare. This reports presents a 54-year-old non-smoker woman with a history of scleroderma who was examined due to aggravation of shortness of ...
متن کاملBevacizumab‐induced chronic interstitial pneumonia during maintenance therapy in non‐small cell lung cancer
Bevacizumab is a monoclonal antibody targeting the vascular endothelial growth factor receptor and a key drug for advanced non-small cell lung cancer. There are few reports describing bevacizumab-induced chronic interstitial pneumonia. A 62-year-old man with advanced non-small cell lung cancer was admitted to our hospital with dyspnea. He previously received four courses of carboplatin plus pac...

BACKGROUND Bevacizumab combined with chemotherapy has become the first-line therapy in advanced nonsquamous non-small-cell lung cancer (NSCLC). However, few studies have focused on cisplatin/pemetrexed with bevacizumab as the first-line therapy to treat advanced nonsquamous NSCLC. Importantly, whether the epidermal growth factor receptor (EGFR) mutations or anaplastic lymphoma kinase (ALK) rear...

Malignant pleural effusion (MPE) is a major problem associated with advanced non-small cell lung cancer for which an optimum treatment strategy has yet to be determined. Notably, vascular endothelial growth factor (VEGF) signaling has been found to influence MPE, and bevacizumab, a VEGF ligand inhibitor, can effectively control MPE. Ramucirumab, a human monoclonal antibody specific for VEGF rec...
