RESUMO
BACKGROUND: Bleomycin pulmonary toxicity (BPT) has been described in Hodgkin's lymphoma (HL) patients treated with bleomycin-containing chemotherapy regimens. METHODOLOGY: We reviewed the records of 164 consecutive HL patients. RESULTS: BPT was observed in 24 of 164 patients (15%). Older age and history of concomitant lung disease were significantly associated with approximately threefold (odds ratio: 3.38; 95% CI: 1.25-9.13; p = 0.02) and sevenfold (odds ratio: 7.19; 95% CI: 2.64-19.54; p < 0.0001) increase in BPT risk, respectively. The actuarial 5-year progression-free and overall survival for BPT and non-BPT groups, were not significantly different. CONCLUSION: In Saudi Arabian HL patients, the risk of BPT and its effect on survival outcome were comparable to that reported from developed countries.

The CheckMate-141 trial led to the approval of nivolumab in platinum-resistant metastatic/advanced squamous cell carcinomas of the head and neck (SCCHN). We evaluated the outcomes of SCCHN patients in Ontario, Canada, treated with nivolumab through retrospective review of the provincial treatment registry. Kaplan-Meier method was used to estimate overall survival (OS) and Cox regression to evaluate the prognostic effect of selected factors. Nivolumab was used as second-line therapy after disease relapse for curative-intent platinum chemotherapy (PC) (indication 1-I1), as second-line therapy post-PC in noncurative intent (indication 2-I2), and as first-line therapy in noncurative intent due to contraindication for PC (indication 3-I3). The median OS for patients treated with nivolumab was 5.8 months (95% CI: 4.5-7.3), and the 1-year OS was 28.4% (CI: 2.10-36.1). When patients with I3 were excluded to match inclusion criteria for CheckMate-141, median OS was 4.8 months (CI: 3.6-6.7) with 1-year OS of 21.8% (14.4-30.1). Patients with lower body surface area (BSA) (<1.81) had a median OS of 3.9 months (CI: 3.1-6.7) versus 9.0 months (CI: 6.5-14.8) in those with higher BSA, hazard ratio (HR)=0.12 (CI: 0.04-0.39, P <0.001). Patients receiving nivolumab for I1 had a median OS of 7.2 months (CI 3.8-9.8) versus 11.9 months (CI: 6.2-not reached) for I3, HR=1.73 (CI: 0.94-3.16). Patients receiving nivolumab for I2 had a median OS of 3.9 months (CI: 2.9-5.4) as compared with I3, HR=3.27 (CI: 1.80-5.94). Real-world analysis of patients with advanced/metastatic SCCHN in Ontario, Canada, treated with nivolumab demonstrates poorer median OS compared with CheckMate-141 trial. Lower BSA was a predictor of poorer median OS.

BACKGROUND: Hodgkin lymphoma (HL) exhibits considerable clinicopathological variations in different parts of the world. This study was prompted by the limited availability of HL data in developing countries (particularly long-term outcomes). METHODS: We performed a retrospective review of eligible adult HL patients treated at 3 tertiary centers in Saudi Arabia between January 1997 and December 2012. RESULTS: The review included 340 patients with a median age of 26 years (range 15-82 years); 53% were male, 74% had an advanced stage, 22% had bulky disease, and 70% had low-to-intermediate risk according to the International Prognostic Score. Nodular sclerosis was the most common histological subtype (59%). Adriamycin, bleomycin, vinblastine, and dacarbazine (ABVD) was offered to 92% and radiotherapy to 43%. Initial therapy outcomes were complete response, partial response, and progressive disease in 91%, 5%, and 2% of patients, respectively. At a median follow-up of 39 months, the actuarial freedom from treatment failure at 5 years was 74%, with a 5-year overall survival of 91%. Multivariate analysis showed that advanced disease stage and high-risk international prognostic index independently predicted an adverse outcome. CONCLUSION: Our Saudi patient population exhibited outcomes that were comparable to those reported in developed countries.
