Bladder cancer is often characterized by a multifocal growth pattern. This observation has given rise to the hypothesis of “field cancerization,” predicting a polyclonal origin of multiple tumors rising from an area of independently transformed mucosa cells. On the other hand, genetic studies suggested a monoclonal origin.

El cáncer de vejiga o cáncer vesical es un tipo de tumor maligno que aparece en la vejiga urinaria. Los principales factores para el desarrollo del cáncer de vejiga incluyen productos químicos específicos, que se encuentran fundamentalmente en el humo de los cigarrillos. En los países del Tercer Mundo, ciertas infecciones parasitarias. El tratamiento del cáncer vesical gira en función de la extensión del mismo, generalmente se resuelve con quimioterapia, la remoción de

Results: Multifocal/multicentric tumors were seen in 107 (15.4%) of the 697 breast cancer patients. pT and pN stage were related with the presence of multifocal/multicentric tumors. As tumor size increased and the number of axillary lymph nodes metastasis increased, the incidence of M/M increased significantly (P=0.003 vs. P=0.02, respectively).

The bladder is a hollow organ in the lower part of the abdomen.It is shaped like a small balloon and has a muscle wall that allows it to get larger or smaller to store urine made by the kidneys.There are two kidneys, one on each side of the backbone, above the waist. Breast cancer diagnosed at a young age and multifocal breast cancers have both been widely described as independent poor prognostic features. 4, 6, 10, 11, 18, 23, 25 Another known prognostic factor, tumor grade, was shown to be an independent prognostic factor in our multivariate models for OS and RFS. J 100(204) . Nippon Med. Sch., Vol.54, No.2 (1987) Preliminary Note A new radical cystectomy for advanced or multifocal urinary bladder cancer Ninety-four (11.1%) of 848 women had multifocal breast cancer and of these 49 women (52.1%) had axillary node involvement compared with 37.5% with unifocal breast cancer (P =.007).The use of aggregate dimension reclassified significant numbers of multifocal tumors at a more advanced stage. Papillary thyroid cancer makes up about 85% of all thyroid cancers and overall has a good prognosis. It is not completely clear whether multifocal Papillary thyroid cancer is more aggressive and is more associated with chance of recurrence or spread outside of the neck than unifocal Papillary thyroid cancer.

Background: Multifocal/multicentric(MF/MC) may be observed in 20% of patients with breast cancer.According to AJCCstaging system, the T stage of a tumor is determined based on the size of the largest lesion in the breast; however, some data suggest that considering the total size of the lesions is more valuable.We investigated and compared the prognostic value of determining the T stage Multifocal breast cancer is a subtype of breast cancer when two or more tumors start to form within the same breast. All the tumors originate from one parent tumor. Multifocal breast tumors may also be present in same quadrant or section of the breast. It is different from multi-centric breast cancer.

2015-01-14 · The biological and clinical significance of multifocal and multicentric (MF/MC) breast cancers and the choice of appropriate surgical treatment for these tumors are still debated. 1158 women operated on for a stage I-III breast cancer were included in this retrospective study; clinical and pathological data were obtained from the institutional database of the Department of Oncology of the

Para el resto del mund Compiler, multifocal means that there was cancer found in more than one area with unifocal meaning only one area had cancer.
