Background: The genotyping of Human Papillomavirus (HPV) will improve knowledge about the local epidemiological association of this virus with adenocarcinoma.

Aim: To determine the frequency of HPV genotypes in biopsies of women with uterine cervical adenocarcinoma in a geographic region of Chile.

Materials And Methods: Forty-one cervical biopsies with a pathological diagnosis of adenocarcinoma, corresponding to all women diagnosed with this cancer between 2002 and 2004, were analyzed.

Background: The loss of tumor suppressor gene function damages the defensive mechanisms that protect the indemnity of genetic material. Promoter gene methylation is one of the inactivation mechanisms of suppressor genes.

Aim: To study the methylation pattern of a group of genes in biopsy samples of gastrointestinal tumors.

Background: The association of different genotypes of human papilloma virus (HPV) with cervical cancer is well known. However, there is little information about their association with pre-cancerous lesions.

Aim: To assess the frequency of different HPV genotypes in pre cancerous cervical lesions.

Background: The association between some specific human papilloma virus (HPV) types and cervix cancer is well known. However, the genetic conditions that favor the development of cervical cancer are less well known.

Aim: To determine the presence of satellite instability (MSI) in preneoplastic and neoplastic lesions of the cervix and correlate these findings with HPV genotypes.

Background: t(12;21) (p12;q22) and t(9;22) (q34;q11) translocations have prognostic significance in acute lymphoblastic leukemia (ALL). The fusion genes TEL/AML1 y BCR/ABL, generated by these translocations, can be easily detected using molecular biology technique.

Aim: To study the frequency of TEL/AML1 y BCR/ABL fusion genes in children with ALL.
