Metallothioneins are a family of small, cysteine-rich proteins with many functions. Immunohistochemical evaluation of all metallothionein 1 + 2 isoforms in colorectal tumors has demonstrated an important down-regulation compared with normal tissue, although its prognostic significance is unclear. Moreover, the contribution of individual isoforms to overall(More)
Despite NK cells being originally identified because of their ability to kill tumor cells in vitro, only limited information is available on NK cells infiltration of malignant tumors, especially in humans. NK cells infiltrating human colorectal carcinomas (CRCs) were analyzed to identify their potential protective role in an antitumor immune response. The(More)
BACKGROUND The non-surgical management in a selected group of rectal cancer patients has shown promising results with adequate follow up. AIMS describing the results of the non-surgical management in patients with complete clinical response, with a close follow up. METHODS Between 2006 and 2015, patients with rectal cancer, stages I-III, without(More)
The clinical outcome of colorectal cancer (CRC) is associated with the immune response; thus, these tumors could be responsive to different immune therapy approaches. Natural killer (NK) cells are key antitumor primary effectors that can eliminate CRC cells without prior immunization. We previously determined that NK cells from the local tumor environment(More)
14142 Background: PDNEC-Small cell (OMS Clasification, grade III)of the GI tract are rare diseases. Small cel represent 0,1% to 1% of all GI malignancies, and are included in the group of PDNEC but: Do these group behave biologically and respond to treatment in the same way? Trying to elucidate this matter, we performed a retrospective analysis of our group(More)
13580 Background: The morbidity of pelvic recurrences from colorectal tumors (PRCT) represents a challenge for the oncology multidisciplinary team. Surgical treatment is the best option for palliation and in several series it offers long term local control in 30% of the cases. OBJECTIVE To perform a retrospective analysis of patients (pts) surgically(More)
