Linfoma de Hodkin en Chile: Experiencia de 15 años del Programa Nacional de Cáncer del Adulto / Hodgkin lymphoma in Chile: Experience of the national adult cancer program

Background: Hodgkin lymphoma is a highly curable disease. Aim: To evaluate the clinical characteristics and the treatment results of Hodgkin lymphoma patients of the National Cancer Program in Chile. Patients and methods: Prospective assessment of 682 patients treated in 18 adult cancer centers. Progression free survival (PFS) and overall survival (OS) were calculated. Median follow up was 127, 95, 87, 72 and 50 months for C-MOPP, radiotherapy (RT), C-MOPP/ABV, NOVP and ABVD, respectively. Results: Median age was 37 years (15-84). Nodular sclerosis and mixed cellularity were equally expressed. Advanced stages (III & IV) were present at diagnosis in 61 percent of cases. Age over 40 was an adverse prognostic factor (p <0.001). The rate of PFS at 5 and 10 years for early stages was 73 percent and 66 percent with RT, 80 percent and 74 percent with C-MOPP+RT, 73 percent and 71 percent with C-MOPP/ABV, 59 percent and 59 percent with NOVP+RT, and 81 percent with ABVD+RT, at 5 years, being significantly lower for NOVP (p =0.02). The rate of OS at 5 and 10 years for advanced stages was 82 percent and 70 percent with RT, 82 percent and 76 percent with C-MOPP+RT, 82 percent and 80 percent with C-MOPP/ABV, 68 percent and 60 percent with NOVP, and 85 percent with ABVD at 5 years, also significantly lower for NOVP (p =0.04). For advanced stages, the rate of PFS at 5 and 10 years was 49 percent and 43 percent with C-MOPP, 69 percent and 62 percent with C-MOPP/ABVD or C-MOPP/ABV, and 71 percent at 5 years with ABVD, significantly lower for C-MOPP (p =0.01). The rate of OS at 5 and 10 years was 52 percent and 46 percent with C-MOPP, 70 percent and 63 percent with C-MOPP/ABVD or C-MOPP/ABV and 76 percent with ABVD at 5 years, significantly lower for C-MOPP (p =0.0002). Conclusions: Age over 40 years was an adverse prognostic factor. C-MOPP/ABVD, C-MOPP/ABV and ABVD had comparable results and reached a high tumor control and overall survival in both early...

Prevalencia de afección hepática, alcoholismo, hepatitis B, C y HIV en pacientes con antecedentes de consum / Prevalence of hepatic involvement, alcoholism, hepatis B, C and HIV in patients with background history of drug use

Drug addicts frequently have liver diseases for different reasons: alcohol abuse, the drugs themselves, but more often hepatitis B and C infections. AIDS is common in this population as well and could also affect the liver directly or in the form of hepatocellular or biliary damage. We conducted this study to determine the prevalence of liver diseases, alcoholism, hepatitis B and C infections, and HIV positivity in this population. We studied a cohort of 137 persons, all with a history of drug abuse, and investigated the quantity of alcohol intake, the kind of drug used, and he routes of drug administration. RESULTS: We found liver disease in 33.6%. The prevalence of alcoholism was 65.4%, of HCV 67.3%, and of HBV 17.3%. HDV was undetectable, whereas we found HIV at a frequency of 17.3%. HCV RNA was detected in 85.4% of HCV. The drug most often used was cocaine at 90.4%, followed by marihuana at 88.3%; LSD use occurred in 17.5%. We found parenteral drug use in 43.1%. We performed 22 liver biopsies, 21 associated with HCV, and detected histological changes consistent with chronic hepatitis in 17, with cirrhosis in 4, and with hepatocellularcarcinoma in 1.
