ABSTRACT

Comparar carcinoma lobulillar infiltrante y carcinoma ductal infiltrante a largo plazo según estadio, tratamiento quirúrgico, terapia neoadyuvante, adyuvante. Estudiamos en la base de datos de CECLINES 841 pacientes, el lobulillar representa 7,25% (61) y ductal 51,24% (431). El seguimiento global 22 años con promedio de 5 años. La sobrevida global: lobulillar 68,1% vs. 60,9% ductal (P=0,772), por estadio fue: I lobulillar 96,3% ductal 90,5 II 94,4% y 88,4% III 90,5% 83,2% (P=0,023). La expresión de receptores de estrógenos positivos en comparación a los CDI fue 87,7% vs. 74,7%,(P=0,031) sobrevida 96,9% vs. 94,0% (P=0,033). El tratamiento preservador del lobulillar en comparación aductal 57,4% vs. 63,2% (P=0,949) y la sobrevida 85,4% vs. 82,9% (P=0,001). La sobrevida de lobulillar sometidos a quimioterapia primaria, quimioterapia adyuvante, radioterapia y hormonoterapia adyuvante en relación al grupo ductal fue 93,4% vs. 91,3%, 91,5% vs. 89,7%, 92,5% vs. 89,8% 92,5% vs. 88,4%, respectivamente (P<0,05). La sobrevida global es igual, la sobrevida por estadio favorece al lobulillar estos presentan más receptores positivos y sobrevida mejor. La tendencia a tratamiento preservador en lobulillar es mayor encontrando excelentes cifras de sobrevida. Dado el perfil hormonal y sobrevida según receptores las pacientes con lobulillar infiltrante son candidatas a participar en protocolos de hormonoterapia primaria. Generalmente el tratamiento para ambos grupos es similar.


Compare infiltrante lobulillar carcinoma and ductal carcinoma in long-term follow up as stage surgical treatment, neoadyuvante, adjuvant therapy. We studied in CECLINES data base 841 patients; lobulillar represents 7.25% (61) and 51.24% ductal (431). The overall followup was up to twenty two years with an average of five years. The overall survival for lobulillar was 68.1%and for ductal 60.9% (P=0.772), the survival according to state was: I lobulillar 96.3% ductal 90.5, II 94.4% vs. 88.4 III 90.5 and 83.2 respectively (P=0.023). Estrogen receptors positive expression for lobulillar compared to ductal was 87.7% vs. 74.7%, (P=0.031) and its survival 96.9% vs. 94.0% (P=0.033). The breast conserving surgery for lobulillar compared to ductal was 57.4% vs. 63.2% (P=0.949) survival 85.4% vs. 82.9% (P=0.001). The survival reported for patients with lobulillar who received neoadyuvante chemotherapy adjuvant chemotherapy radiotherapy and adjuvant hormonotherapy compared to ductal was 93.4% 91.3%, 91.5% 89.7%, 92.5% 89.8% 92.5% 88.4%, respectively P<0.05. The overall survival is equal, survival favors. The lobulillar have more positive receptors and survival is better. The tendency to conservative treatment in lobulillar is increasingly. Given the hormonal profile and survival according to estrogen receptors patients with ILC, are probably good candidates to participate in neoadyuvante hormone therapy protocols. Usually the treatment is the same or similar for both groups.

ABSTRACT

Describir los primeros 100 casos de carcinoma ductal in situ en nuestra institución. 100 casos tratados adoptamos la definición de mic de Silver y Tavassoli: 77 fueron puros y 23 mic. En 69 por ciento se practicó cirugía preservadora, 31 por ciento mastectomía, 24 por ciento con reconstrucción, una bilateral y 7 por ciento sin reconstrucción. 64 por ciento recibió radioterapia complementaria. 36 por ciento el tratamiento fue cirugía sola. 77 por ciento recibieron terapia hormonal adyuvante. En 46 por ciento practicamos biopsia de ganglio centinela: 25 por ciento in situ puros y 21 por ciento mic. En 83 por ciento la presentación fue micro calcificaciones. El patrón histológico cribiforme y mixtos, los más frecuentes, 75 por ciento. El tamaño mamográfico e histológico coincidieron, 20 mm, promedio. El 87 por ciento grado nuclear II o III actividad mitótica 82 por ciento fue baja o moderada sólo 4 por ciento alta. El 78 por ciento presentó necrosis. De 25 pacientes con in situ puro, que se les practicó ganglio centinela ninguna presentó enfermedad ganglionar y los 21 con in situ mic, 9,52 por ciento presentaron metástasis. 2 por ciento recaídas locales, con enfermedad infiltrante; una a 52 meses, los otros a 58 meses. Una sin radioterapia, se trataron con mastectomía de rescate. No ocurrieron muertes por enfermedad. El buen manejo de los casos, traduce satisfactorios resultados de sobre vida libre de enfermedad y sobrevida global. Podemos seleccionar un sub-grupo de pacientes a quienes les pueda omitir la radioterapia sin aumentar el riesgo de mortalidad.


Describe first 100 cases of ductal carcinoma in situ in our institution. 100 cases treated adopted the definition of mic by Silver and Tavassoli: 77 pure and 23 mic. 69 percent we performed breast conserving surgery 31 percent total mastectomy 24 percent reconstruction, 1 was bilateral, 7 percent without reconstruction. 64 percent received complementary radiotherapy. 36 percent treatment was surgery alone. 77 percent recieved hormonal adjuvant therapy. 46 percent we performed sentinel lymph node biopsy: 25 percent were pure and 21 percent mic. 83 percent initial form of presentation was micro calcifications. The histological type was cribiform and mixed (75 percent). The mammographic and histological size matched 20 mm average. 87 percent were nuclear grade II and III, 82 percent of the mitotic activity was moderate or low only 4 percent were high. 78 percent had necrosis. Out of the 25 patients with pure in which we practice none presented ganglion disease and out of the 21 patients with mic, 9.52 percent presented ganglion metastasis. 2 percent had local recurrence, both of them with invasive disease, one 52 months the other one at 58 month from surgery. One didn´t received radiation. Both were treated with rescue mastectomy. There was no death diseases related. Adequate and good management of cases results related to disease free survival and overall survival. We can classify sub group of patients in which may avoid radiation without increasing the risk of mortality.
