The safety and efficacy of BLENOXANE (bleomycin sulfate injection) 60 units and tetracycline (1 g) as treatment for malignant pleural effusion were evaluated in a multicenter, randomized trial. Patients were required to have cytologically positive pleural effusion, good performance status (0,1,2), lung re-expansion following tube thoracostomy with drainage rates of 100 mL/24 hours or less, no prior intrapleural therapy, no prior systemic BLENOXANE (bleomycin sulfate injection) therapy, no chest irradiation, and no recent change in systemic therapy . Overall survival did not differ between the BLENOXANE (bleomycin sulfate injection) (n=44) and tetracycline treatment (n=41) groups. Of patients evaluated within 30 days of instillation, the recurrence rate was 36% (10/28) with BLENOXANE (bleomycin sulfate injection) and 67% (18/27) with tetracycline (p=). Toxicity was similar between groups.

Preterm newborns are known to be at higher risk for bronchopulmonary dysplasia with extended exposure to high concentrations of oxygen. [38] Other groups at higher risk for oxygen toxicity are patients on mechanical ventilation with exposure to levels of oxygen greater than 50%, and patients exposed to chemicals that increase risk for oxygen toxicity such the chemotherapeutic agent bleomycin . [35] Therefore, current guidelines for patients on mechanical ventilation in intensive care recommends keeping oxygen concentration less than 60%. [34] Likewise, divers who undergo treatment of decompression sickness are at increased risk of oxygen toxicity as treatment entails exposure to long periods of oxygen breathing under hyperbaric conditions, in addition to any oxygen exposure during the dive.

The word “cure” means there are no cancer cells left in the body and cancer will never come back. Depending on the cancer type and stage, this may be the true goal of therapy. However, it is very difficult to prove all cancer cells are gone. Even though images, like X-rays and MRI’s, and blood tests may not show any signs of cancer, there can be a small amount of cancer cells still left in the body. Because of this, doctors use the word “remission” is used more often. This means there are no signs or symptoms of cancer. Patients in remission are followed closely for any signs of cancer returning. Sometimes, more chemotherapy may be given while in remission to prevent the cancer from coming back.

To monitor the onset of pulmonary toxicity, roentgenograms of the chest should be taken every 1 to 2 weeks (see WARNINGS ).  If pulmonary changes are noted, treatment should be discontinued until it can be determined if they are drug related.  Recent studies have suggested that sequential measurement of the pulmonary diffusion capacity for carbon monoxide (DL co ) during treatment with Bleomycin may be an indicator of subclinical pulmonary toxicity.  It is recommended that the DL co be monitored monthly if it is to be employed to detect pulmonary toxicities, and thus the drug should be discontinued when the DL co falls below 30% to 35% of the pretreatment value.
