[Cancer in AIDS patients: experience at a general hospital in the Province of Buenos Aires]. / Cáncer en enfermos de SIDA. Experiencia en un hospital general en la Provincia de Buenos Aires.

Twenty three HIV+ patients with cancer (2% of the infected population: 1100 patients) were treated at our Hospital between January 1987 and July 1997. Twelve patients (52%) had Kaposi's sarcoma (KS), five (22%) presented non Hodgkin lymphoma--B cell type (NHL), the remaining patients presented other non AIDS defining neoplasias. The patients with NHL presented, at the time of diagnosis, several infrequent localizations, poor tolerance to chemotherapy with a mean survival of 3 months. The patients with Kaposi sarcoma had neither positive response to recombinant Interferon alfa 2 nor to the etoposide regimens. A relatively high percentage (13%) of Hodgkin-disease (HL) was observed. Unlike previously consulted data, there was no apparent increased incidence of NHL. HIV+ patients with cancer who underwent conventional radiotherapy presented major toxicity and adverse effects not currently observed in non HIV+ patients.

[Colorectal cancer: surgery or is there something else?]. / Cáncer de colón y recto: cirugía, hay algo Más?

The standard modality to treat colorectal cancer in potentially curable patients is, undoubtedly, surgery. The concept of precautional chemotherapy used in tumors located elsewhere, has put forward a clinical trial that proved its effectiveness and improved survival. We report the use of two modalities (chemotherapy and radiotherapy) along with surgery as part of a multidisciplinary treatment of patients with colorectal cancer.
