[Survival of patients with metastatic breast cancer according to pathological types of tumors].

Background: The prognosis of breast cancer (BC) is in part determined by the stage at diagnosis and its pathological characteristics.

Aim: To evaluate the association between survival of women with metastatic breast cancer and pathological features of the tumor.

Patients And Methods: We obtained clinical and pathological data from patients diagnosed with a metastatic BC between 1999 and 2013.

[Umbilical cord hematopoietic precursors transplantation. Report of five patients].

Hematopoietic precursors transplantation is a therapeutic alternative for leukemia, some metabolic diseases and some immune deficiency syndromes. In its allogeneic variety leukemia eradication is based in the conditioning prior to transplantation and the allograñ effect against leukemia. Umbilical cord blood is an alternative source of hematopoietic precursors when there are no HLA compatible relatives available.

[Cytokeratin 20 as a marker of tumor progression or dissemination in patients with colorectal cancer].

Background: Colorectal cancer relapses or metastasizes in 30% of cases. Cytokeratin 20 is present in 95% of colorectal tumors and their metastases and could be used as a marker to detect tumor cells.

Aim: To assess the usefulness and prognostic value of peripheral blood and bone marrow cytokeratin 20 determinations in patients with colorectal cancer.

[Treatment of metastatic gastrointestinal stromal tumors with Imatinib: report of four cases].

Gastrointestinal stromal tumors (GIST) have mutations of the tyrosine kinase receptor. When they are localized, the treatment of choice is surgical excision, but advanced tumors have a limited response to chemo or radiotherapy. Imatinib (STI571 or Glivec) is a selective inhibitor or tyrosine kinase proteins that has been used successfully in the treatment of advanced GIST.

[Endovascular treatment of superior vena cava syndrome].
