RESUMO

Introducción: El cáncer de mama en mujeres muy jóvenes pese a su baja incidencia, representa un gran problema en salud, por el difícil diagnóstico, las connotaciones negativas de la terapéutica y su mal pronóstico. Objetivo: El objetivo de este estudio es evaluar las características del cáncer de mama en mujeres muy jóvenes de 30 años o menos, desde el punto de vista de los factores de pronóstico, predicción y de los antecedentes familiares. Material y métodos: Análisis de un estudio observacional, descriptivo y retrospectivo, mediante una búsqueda múltiple efectuada en varios centros de diagnóstico y tratamiento. Resultados: Se identificaron 20 mujeres con cáncer de mama infiltrante de 30 años. En todos los casos se trataron de tumores palpables, de ellos 2 casos fueron estadios IV de inicio. Dos (2) cánceres y embarazo. Receptores de estrógeno y progesterona positivos se detectaron en 50% de la serie. El grado histológico fue G2 o G3 en el 100% de los casos. La sobreexpresión Cerb2 presente en 28%. El 39% de los tumores fueron triple negativos. El antecedente familiar estuvo presente en 5 casos (25%). El seguimiento promedio fue de 47 meses (12-72). Ocho (8) pacientes fallecieron y 6 pacientes presentaron recaídas a distancia. Los datos obtenidos confirman la agresividad de esta patología en mujeres muy jóvenes y reafirman la presencia de antecedentes heredo-familiares. Conclusiones: Las mujeres muy jóvenes con cáncer de mama deberían tener una muy especial atención de un equipo multidisciplinario. En estas pacientes se debe tener en cuenta el daño ocasionado por una menopausia precoz inducida, con todos los cambios y síntomas inherentes a este estado hormonal. Es imprescindible el manejo de la preservación de la fertilidad, así como un apropiado soporte psicosocial. Las pacientes con antecedentes heredo-familiares se verían beneficiadas ingresando al cribado en edades más tempranas.

RESUMO

La ixabepilona es un análogo semisintético de la epotilona B se une directamente a las subunidades de β-tubulina en los micro túbulos, lo que conduce a la muerte celular. Aunque los resultados de ensayos clínicos de ixabepilona han sido alentadores, la edad media de los pacientes en estos estudios fue de alrededor de 52 años. El cáncer de mama en mujeres más jóvenes (<40 años) tiene una fisiopatología más agresiva, con mayor riesgo de recurrencia y resultados inferiores. Hay poca información disponible sobre el tratamiento del cáncer de mama en América Latina, que puede ser especialmente difícil debido a consideraciones financieras y problemas con el acceso a los servicios de salud. Esta serie de estudios de casos y revisión proporciona información sobre el uso de ixabepilona para el tratamiento de mujeres jóvenes con cáncer de mama en América Central y del Sur.


The ixabepilona is a semi-synthetic analog of the epotilona B it has a directly union of sub unity of β-tubuline in the micro tubules, it mechanism conduce to the cellular death. The results of the clinical studies of ixabepilona were encouraging; the middle age of the patients in these studies was of 52 years old. The breast cancer in young women less than (<40 years) has a physiopathology more aggressive with mayor risk of recurrence and we obtain inferior results. There is little available information about the breast cancer in Latin America; it has been especially difficult for the financial considerations and problems with the access to the health services. In these series of clinical cases and revision let us information about the use of ixabepilona for the treatment of young women with breast cancer in Central America and in the Sur.

RESUMO

CONTEXT: In a randomized phase 3 trial, 400 mg of sorafenib twice daily prolonged overall survival of patients with advanced hepatocellular carcinoma (HCC) and Child-Pugh A disease. In a phase 1 study, sorafenib combined with doxorubicin, 60 mg/m(2), was well tolerated by patients with refractory solid tumors. The combination of sorafenib and doxorubicin in patients with advanced HCC has not been evaluated in a phase 2 or 3 trial. OBJECTIVE: To evaluate the efficacy and safety of doxorubicin plus sorafenib compared with doxorubicin alone in patients with advanced HCC and Child-Pugh A disease. DESIGN, SETTING, AND PATIENTS: In a double-blind phase 2 multinational study, conducted from April 2005 to October 2006, 96 patients (76% male; median age, 65 years [range, 38-82 years]) with advanced HCC, Eastern Cooperative Oncology Group performance status 0 to 2, Child-Pugh A status, and no prior systemic therapy were randomly assigned to receive 60 mg/m(2) of doxorubicin intravenously every 21 days plus either 400 mg of sorafenib or placebo orally twice a day. The date of the last patient's follow-up was April 2008. MAIN OUTCOME MEASURE: Time to progression as determined by independent review. RESULTS: Following complete accrual, an unplanned early analysis for efficacy was performed by the independent data monitoring committee, so the trial was halted. The 2 patients remaining in the placebo group at that time were offered sorafenib. Based on 51 progressions, 63 deaths, and 70 events for progression-free survival, median time to progression was 6.4 months in the sorafenib-doxorubicin group (95% confidence interval [CI], 4.8-9.2), and 2.8 months (95% CI, 1.6-5) in the doxorubicin-placebo monotherapy group (P = .02). Median overall survival was 13.7 months (95% CI, 8.9--not reached) and 6.5 months (95% CI, 4.5-9.9; P = .006), and progression-free survival was 6.0 months (95% CI, 4.6-8.6) and 2.7 months (95% CI, 1.4-2.8) in these groups, respectively (P = .006). Toxicity profiles were similar to those for the single agents. CONCLUSIONS: Among patients with advanced HCC, treatment with sorafenib plus doxorubicin compared with doxorubicin monotherapy resulted in greater median time to progression, overall survival, and progression-free survival. The degree to which this improvement may represent synergism between sorafenib and doxorubicin remains to be defined. The combination of sorafenib and doxorubicin is not yet indicated for routine clinical use. TRIAL REGISTRATION: clinicaltrials.gov Identifier: NCT00108953.

RESUMO

The purpose of this study was to evaluate the efficacy and toxicity of docetaxel as single-agent neoadjuvant chemotherapy in locoregionally advanced cervical carcinoma. Between April 1998 and August 2000, 38 untreated patients with International Federation of Gynecology and Obstetrics stages IIB to IVA were entered onto this study. The median age was 44 years (range: 25-66 years). Stages: IIB 22 patients, IIIB 15 patients, and IVA 1 pt. Treatment consisted of docetaxel 100 mg/m2 IV infusion during 1 hour. Standard premedication with dexamethasone, diphenhydramine, and ranitidine was used. Cycles were repeated every 3 weeks for three courses, followed by radical surgery when it was judged appropriate, or definitive radiotherapy. Both staging and response assessment were performed by a multidisciplinary team. 106 cycles of therapy were administered; all patients were evaluable for TX, whereas 35 were evaluable for response (3 patients refused further treatment after the first cycle of therapy). Complete response (CR): 1 patient (3%); partial response: 11 patients (31%), for an overall objective response rate of 34% (95% CI: 15-53%); no change (NC): 16 patients (46%); and progressive disease: 7 patients (20%). Six patients (17%) underwent surgery and a pathologic CR was confirmed in 1 of them. The median time to treatment failure and the median survival have not been reached yet. The limiting toxicity was leukopenia in 25 patients (69%) (G1-G2: 14 patients, G3: 10 patients, and G4: 1 patient). Neutropenia: 28 patients (78%) (G1-G2: 10 patients, G3: 8 and G4: 10). Myalgias: 17 patients (47%) (G1-G2: 15 patients and G3: 2 patients). Emesis: 21 patients (55%) (G1-G2: 19 patients and G3: 2 patients). Alopecia G3: 13 patients (36%); rash cutaneous 26 patients (68%) (G1-G2: 22 patients and G3: 4 patients). There were no hypersensitivity reactions or fluid-retention syndrome. The received dose intensity was 91% of that projected. Docetaxel is an active drug against advanced cervical carcinoma with moderate toxicity. Further evaluation in association with other agents is clearly justified.

RESUMO

A phase II trial was performed to evaluate the efficacy and toxicity of the novel combination of vinorelbine and paclitaxel as first-line chemotherapy in patients with stages IIIB and IV non-small-cell lung cancer. From January 1997 to September 1999, 34 patients (9 stage IIIB and 25 stage IV) received a regimen consisting of the following: vinorelbine 30 mg/m2 20 minutes intravenous (i.v.) infusion, days 1 and 8; and paclitaxel 135 mg/m2 3-hour i.v. (starting 1 hour after vinorelbine) on day 1. Cycles were repeated every 28 days until progression of disease or unacceptable toxicity development. The median age was 57 years (range 41-70 years); median performance status was 1. Histology was as follows: squamous cell in 24 (71%), large cell in 1 (3%), and adenocarcinoma in 9 (26%). All patients are evaluable for toxicity, whereas 30 are evaluable for response (4 patients refused treatment). Objective response was recorded in 4 of 30 patients (13%, 95% CI 1-25%). No complete response was observed. Partial response was recorded in 4 patients (13%), no change in 10 patients (34%), and progressive disease in 16 patients (53%). The median time to treatment failure was 4 months and median survival was 9 months. The limiting toxicity was myelosuppression: leukopenia in 23 patients (68%), whereas neutropenia was observed in 25 patients (78%). Peripheral neurotoxicity developed in 14 patients (41%) (without G3 or G4 episodes), and constipation (G1-G2: 10 patients), myalgia (G1-G2: 11 patients), diarrhea (G1-G2: 7 patients), and stomatitis were observed in 7 patients. Vinorelbine-paclitaxel combination showed only modest activity against locoregionally advanced or metastatic NSCLC.
