Bevacizumab (Avastin) has unprecedented survival benefit in patients with metastatic colorectal cancer. Trials are already in progress to investigate the potential of bevacizumab in indications including metastatic renal cell cancer (RCC), non-small cell lung cancer (NSCLC), pancreatic cancer, breast and ovarian cancer. Bevacizumab offers the potential to increase survival without substantially altering the toxicity profile in these tumor types. Bevacizumab has shown activity in patients with refractory metastatic RCC, where progression-free survival (PFS) was significantly longer in patients treated with bevacizumab (10 mg/kg every 2 weeks) than those treated with placebo (hazard ratio=2.55, p<0.001). In addition, combining bevacizumab with erlotinib (Tarceva) has shown a median time to progression of more than 11 months. In NSCLC, a phase II trial revealed that adding bevacizumab to chemotherapy increased therapeutic benefit compared with chemotherapy alone. Adverse events were mild and easily managed, but six patients receiving bevacizumab developed severe hemoptysis. Entry criteria for NSCLC trials have been adjusted to exclude patients with squamous cell histology to try to avoid this issue. Adding bevacizumab (10 mg/kg) to the current standard of care, gemcitabine, in stage IV pancreatic cancer has also shown promising efficacy. Partial responses were seen in 19% of patients, with a further 48% having stable disease. Several ongoing clinical trials are also studying bevacizumab with various chemotherapy and radiotherapy regimens. Bevacizumab combined with carboplatin (Paraplatin)/paclitaxel (Taxol) was further examined in a phase III randomized trial that accrued 878 patients with advanced non-squamous cell NSCLC. Patients given chemotherapy (paclitaxel and carboplatin) plus bevacizumab had a higher response rate, longer PFS and an increase in survival compared with patients on chemotherapy alone. Both regimens were generally well tolerated. Bevacizumab has also shown activity in patients with metastatic breast cancer. In 715 patients, a significant, 2-fold increase in response rate was observed in patients receiving bevacizumab plus paclitaxel compared with paclitaxel alone. Median PFS was also significantly increased (p<0.001). Bevacizumab has the potential to provide significant efficacy benefits for patients with metastatic RCC, NSCLC, pancreatic cancer, and other tumor types when used first line in combination with standard therapy.

Ovarian cancer is the seventh most common cancer in women and the eighth most common cause of cancer death in the world with an overall 5-year survival rate of <50%. (1) The most common age of presentation is at the perimenopausal age group and two-thirds of them present with advanced stage of disease. (2) Thoracic metastases occur in up to 50% of patients. Pleural effusion is the most common presentation of thoracic metastases in these patients, whereas pulmonary parenchymal metastases, lymphangitis, and nodal involvement are less commonly reported. (3) Tracheobronchial involvement is rare with few cases reported in literature. Herewith, we are presenting a case of ovarian cancer in a young female with both lung parenchymal and endobronchial metastases. Bronchoscopy revealed endobronchial tumor in right lower lobe bronchus part of which was covered by yellowish necrotic material. Biopsy showed metastatic ovarian malignancy complicated by aspergillosis. She was started on oral itraconazole along with supportive management following which hemoptysis stopped.
