RESUMO
PURPOSE: Major progress has occurred in multiple myeloma (MM) treatment in recent years, but this is not seen in low- and middle-income countries. MATERIALS AND METHODS: We retrospectively assessed the efficacy and safety of cyclophosphamide, thalidomide, and dexamethasone (cyclophosphamide 400 mg/m2 for 5 days, thalidomide 100 mg once daily, if tolerated, and dexamethasone 40 mg once weekly; in 28-day cycles) in patients with newly diagnosed MM treated at our institution between April 2008 and December 2012. Survival outcomes were estimated by the Kaplan-Meier method. RESULTS: Fifty-nine patients were found to meet the selection criteria. Median age was 56 years (27-78). Fifty-nine percent (n = 35) were male. International Staging System three was found in 24%. The median number of treatment cycles was 11 (range 4-12). After a median of 81-month follow-up (range 5-138 months), the overall response rate was 69.5%. The complete response and very good partial response were 5% and 32%, respectively. Median progression-free survival (PFS) was 35 months (95% CI, 18 to 41). The 3-year PFS was 47.4% (95% CI, 34.5 to 59.6) and 5-year PFS was 24.9% (95% CI, 14.4 to 36.9). The median of overall survival (OS) was 81 months (95% CI, 33 to not reached). The 3-year OS was 63.4% (95% CI, 49.2 to 74.6), and 5-year OS was 57.5% (95% CI, 43.2 to 69.4). The most common adverse event was neutropenia (grade 3 and 4, 30.5%). Out of 23 patients eligible for stem-cell transplantation, 10 (43.5%) proceeded with autologous transplantation. Treatment-related deaths occurred in four patients (6.7%). CONCLUSION: Cyclophosphamide, thalidomide, and dexamethasone achieves good response rates with tolerable toxicity, especially in patients age 65 years or younger representing a feasible approach for patients with MM in low-income health care settings.

Aim: To correlate levels of tumor-infiltrating lymphocytes (TIL) evaluated using the International Immuno-Oncology Biomarker Working Group methodology, and both density of tumor-infiltrating immune cell and clinicopathological features in different malignancies. Methods: 209 pathological samples from gastric cancer, cervical cancer (CC), non-small-lung cancer, cutaneous melanoma (CM) and glioblastoma were tested for TIL in hematoxylin eosin, and density of CD3+, CD4+, CD8+, CD20+, CD68+ and CD163+ cells by digital analysis. Results: TIL levels were higher in invasive margin compartments (IMC). TIL in IMC, intratumoral and stromal compartments predicted survival. CC and gastric cancer had higher TIL in intratumoral; CC and CM had higher TIL in stromal compartment and IMC. CM had the highest density of lymphocyte and macrophage populations. CD20 density was associated with survival in the whole series. Conclusion: Standardized evaluation of TIL levels may provide valuable prognostic information in a spectrum of different malignancies.

PURPOSE: We describe the implementation process of a computerized physician order entry (CPOE) for outpatient chemotherapy at a Latin American hospital, with the intent of providing other institutions with general guidance and insight through our experience. METHODS: In 2012, under the direction of the Department of Medicine of the Instituto Nacional de Enfermedades Neoplásicas, a multidisciplinary team composed of oncologists, nurses, pharmacists, and informatics engineers was formed to develop software for a CPOE for chemotherapy within a preexistent homegrown electronic medical record system in various phases. This included mapping and redesigning processes in an entirely electronic format, integrating the needs of the user for the development of electronic order sets, developing a checkpoint and a warning system to minimize prescription errors, and finally, training all the staff in implementation of the system. RESULTS: A CPOE for outpatient chemotherapy was successfully implemented in 2016. We have successfully standardized 266 chemotherapy orders, including for both solid tumors and hematologic malignancies, on the basis of appropriate guidelines. The software is linked to laboratory results and allows entry of important details for the patient's safety, such as anthropometric information for an automatic dose calculation and ranges for safe prescription. In addition, it is linked to the nursing plan sheets. Finally, it is possible to assess and continuously monitor the complex process of chemotherapy prescription. CONCLUSION: This is the first report of implementation of a CPOE for chemotherapy in our region. The system was designed by a multidisciplinary team with its own resources. Our experience demonstrates the feasibility of computerizing the chemotherapy prescription process, constituting a tangible example for other institutions with potential impact on patient care.

Introducción: El presente artículo resume el proceso de elaboración de la Guía de Práctica Clínica (GPC) para el manejo de dolor en pacientes oncológicos. Este proceso se llevó a cabo con la participación de un equipo multidisciplinario de médicos asistenciales, metodólogos y diversos revisores externos (especialistas con dominio en la metodología y el tema). La priorización de preguntas PICO fue realizada por el Grupo Elaborador de la GPC (GEG), acordando trabajar cinco preguntas PICO. Para dar respuesta a las preguntas se realizó una búsqueda sistemática de GPC, revisiones sistemáticas y estudios primarios. Se utilizó la metodología GRADE y los lineamientos de la normativa nacional para la formulación de recomendaciones. Se formularon 12 recomendaciones (10 fuertes y 2 débiles), 5 puntos de buena práctica clínica y 4 cuadros consensuados sobre el manejo de dolor oncológico. Los temas que abarcaron las recomendaciones para el manejo de dolor en pacientes oncológicos fueron: intervención temprana de tratamiento, terapia analgésica en dolor leve a moderado y en dolor moderado a severo, dolor neuropático e intervenciones no farmacológicas.
