Sumario:Temozolomide (TMZ) given concurrently with radiation (TMZ-RT) is essential in glioma therapy. Pneumocystis jirovecii pneumonia (PCP) prophylaxis is required by provincial and national drug monographs based on two incidents of PCP in a pilot study. There is otherwise limited evidence to inform the need for PCP prophylaxis in this population. METHODS: We conducted a single-centre survey of patients and national survey of physicians on the role of PCP prophylaxis in patients with glioma receiving concurrent TMZ-RT. RESULTS: Fifteen percent (31/212) of physicians and 60% (44/73) of patients completed a survey. The median age of patients was 42 (20-77); 85% (34/40) had completed adjuvant TMZ, and 59% (24/41) were not offered PCP prophylaxis. After reviewing the hypothetical risks of PCP, 13.2% (5/38) of patients were concerned about PCP infection, whereas 26% (10/38) were concerned about potential side effects from prophylactic antibiotics. Physician participants included medical (29%, 9/31) radiation (29%, 9/31), and neuro-oncologists (32%, 10/31). Most physicians (77%, 17/22) felt the evidence informing PCP prophylaxis in this population was weak; 58% (11/19) were not routinely prescribing prophylaxis, and 73% (16/22) felt that PCP prophylaxis should be limited to patients with additional risk factors. Sixty-three percent (22/35) of patients and 57% (12/21) of physicians were interested in a clinical trial to assess the risk of PCP infection in this setting. CONCLUSION: Clinical equipoise exists on the role of PCP prophylaxis during and after TMZ-RT amongst patients and physicians. Rigorous prospective studies need to be conducted to inform and standardize best practices.
