ABSTRACT
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...

The antiemetic effect of tropisetron was studied in 97 cancer patients (67 men, 30 women) receiving cisplatin in doses of 75 mg/m² or higher. On 279 chemotherapy cycles studied (max 6 per patient) 5 mg of tropisetron was admonistered once a day i.v. on day 1 and p.o. on day 2 to 6. Efficacy preventing vomiting and nausea was measured in 24 hour period as: complete control 0 episodes, major control 1 to 2 episodes, minor control 3 to 4 episodes and no control 5 or more episodes. Satisfactory vomiting control (complete and major) was 69 percent, 63 percent, 82 percent,88 percent, 96 percent and 96 percent in days 1 to 6 of cycle 1. Satisfactory nausea control (complete and major) for the same day was 70, 66, 72, 85 92 and 97 percent. Similar data was obtained for the subsequeny cycles. Complete vomiting control was obtained in 47, 35, 56, 72, 81 and 84 percent and for nausea in 42, 39, 48, 64, 81 and 87 percent. 19 patients presented adverse effects (19,6 percent). Only 2 headache episodes had a definitive relation with antiemetic drug. 12 patients discontinued the medication; 6 due to drug inefficacy, 2 to illness unrelated to the drug, 1 to lack of collaboration, and 3 due to other reasons. We conclude that tropisetron allows satisfactory control of acute and delayed vomiting in a high percentage of patients treated with high doses of cisplatin. The drug does not have significant secondary effects. Tropisetron administration in only 1 daily dose implies an evident advantage and a treatment cost reduction

El uso de la quimioterapia preoperatoria (Qx preop) en cáncer de mama localmente avanzado ha disminuido la tasa de pacientes consideradas inoperables y las recidivas locaes, aumentando según algunos la sobrevida libre de enfermedad y la sobrevida total. El objetivo de este trabajo es medir la respuesta del tumos de mama primario a la Qx preop y evaluar la influencia de ésta en la elección del tipo de tratamiento quirúrgico. Entre mayo de 1990 y marzo de 1995, ingresaron al protocolo de Qx preop del IOCPC, 93 pacientes con diagnóstico de cáncer de mama localmente avanzado, siendo evaluables para este estudio 80 pacientes. La Qx preop consistió en 3 ciclos de drogas con los esquemas de (CMF) o (FEC/FAC). La respuesta fue evaluada en comité oncológico al finalizar el tercer ciclo, en que se decidió la secuencia a seguir con el tratamiento, ya sea primero radioterapia (RT) o cirugía dependiendo de la respuesta clínica. La Qx preop tuvo una respuesta clínica completa o parcial en un 39 por ciento de las pacientes, permitiendo realizar un tratamiento conservador en un 16 por ciento de ellas. Con la adición de RT preoperatoria es posible reducir significativamente el número de pacientes consideradas inoperables en el momento de la evaluación inicial
