INTRODUCTION: Thyroid cancer is the most common endocrine neoplasia and the papillary subtype is the most frequent; there are histological and clinical factors associated with a higher risk of recurrence and metastasis. OBJECTIVE: The aim of this study was to examine the histological, prognostic and clinical characteristics of papillary thyroid carcinomas diagnosed at the National Cancer Institute of Colombia. MATERIALS AND METHODS: A retrospective cohort study was carried out on 619 patients with papillary thyroid carcinoma between 2006 and 2012; we analyzed the sociodemographic, histological, prognostic and clinical characteristics...

PURPOSE: The aim of this study was to compare the radioguided occult lesion localization (ROLL) technique with the wire-guided lesion localization (WGLL) technique to assess their efficacy and accuracy in the localization of nonpalpable breast lesions in patients at a unique reference medical center. These patients' reports were negative for malignancy but included highly suspicious imaging findings. METHODS: A controlled clinical trial was designed to compare the WGLL and ROLL techniques in women presenting with breast lesions diagnosed by mammography or ultrasonography at the Instituto Nacional de Cancerología in Bogotá, Colombia, from March 2006 to June 2011...

BACKGROUND: Treatment-related mortality and abandonment of therapy are major barriers to successful treatment of childhood acute lymphoblastic leukemia (ALL) in the developing world. PROCEDURE: A collaboration was undertaken between Instituto Nacional de Cancerologia (Bogota, Colombia), which serves a poor patient population in an upper-middle income country, and Dana-Farber/Boston Children's Cancer and Blood Disorders Center (Boston, USA). Several interventions aimed at reducing toxic deaths and abandonment were implemented, including a reduced-intensity treatment regimen and a psychosocial effort targeting abandonment...

OBJECTIVE: To assess the main clinical, radiographic, and histopathologic features of patients with bisphosphonate-induced osteonecrosis of the jaws (BIONJ). STUDY DESIGN: Patients with BIONJ diagnosed and treated at the Head and Neck Department, Instituto Nacional de Cancerología, Bogotá, DC, Colombia, between January 2012 and February 2014 were retrospectively included. Patients treated with sequestrectomy or curettage were excluded. Specimens from selected patients were reexamined under a light microscope...

INTRODUCTION: The presence of carbapenemase-producing Enterobacteriaceae in hospitals is increasingly common. Patients with advanced cancer who require invasive means for diagnosis, treatment or palliative care, and the use of broad-spectrum antimicrobials to treat secondary infections show increased susceptibility to infections caused by these bacteria. OBJECTIVE: To report the behavior of carbapenemase-producing Klebsiella pneumoniae (CPKP) isolates at the Instituto Nacional de Cancerología in Bogotá between January 2010 and December 2012...

OBJECTIVES: To determine diagnostic accuracy of urinary cytology (smear test) in patients with preoperative diagnosis of urothelial bladder carcinoma. METHODS: Clinical records of the patients with urotelial bladder carcinoma at the Instituto Nacional de Cancerología (Bogotá D.C.,Colombia) from January 2006 to November 2010 were reviewed. Demographic data, pathological reports of preoperative cytology and definitive surgery, tumor classification and time between sample taking for cytology and final pathology were extracted...

INTRODUCTION: Cervical cancer is the leading cause of cancer deaths in the female population in Colombia. The low impact of Papanicolaou smears in reducing cervical cancer mortality in some countries has been attributed to their low reproducibility and high rates of false negatives. OBJECTIVE: To evaluate the quality of the Papanicolaou smears in four regions of Colombia comparing the original report given by provincial cytologists or pathologists with a second report made by a team of expert pathologists from the Instituto Nacional de Cancerología of Colombia...

INTRODUCTION: Staphylococcus aureus is the cause of 11-33% of nosocomial bloodstream infections and has a complication rate close to 50%. S. aureus accounts for 31% of isolates in the Instituto Nacional de Cancerología (INC), in Bogotá, Colombia, and is the main etiological agent of bacteremia. This study describes the risk factors for mortality caused by S. aureus bacteremia in cancer patients. METHODS: This is a retrospective, analytical, observational cohort study of 267 cases of bacteremia caused by S...

OBJECTIVE: Low-income countries, like Colombia, have recorded a low impact on mortality rates due to cervical cancer. This can be partially explained by the cancer control models and their approaches implemented so far. This study adopted a cancer control model designed by the National Cancer Institute (Instituto Nacional de Cancerología) based on interventions at three different levels and on using social strategies founded on a human rights' perspective. METHODS: A participatory community-based intervention was carried out in three phases: diagnosis (2004-2005), intervention (2006) and evaluation (2007)...

UNLABELLED: Human Papillomavirus type 16 (HPV 16) DNA is regularly found in around 50% of all cervical carcinomas. Variants of this type have been found associated with different risks for cervical cancer development. Presence of HPV 16 variants in Colombia has not been previously reported. The aims of this study were to assess the feasibility of non-radioactive PCR-SSCP (polymerase chain reaction single-strand conformation polymorphism) analysis for determination of variability of ORF of E6, variability in the enhancer sequence of the LCR, and for establishment of the distribution of HPV 16 variants in invasive squamous cell carcinoma of the uterine cervix in Colombian women...

Coinfection with multiple types of human papillomavirus (HPV) and its implications for the development of efficacious HPV vaccines is a subject of great interest. To describe the occurrence of concurrent infection with multiple HPV types and to determine whether genital HPV infection modifies the risk of acquiring a new HPV infection with another HPV type, 1610 subjects were monitored for an average of 4.1 years in Bogota, Colombia. Information on risk factors for HPV infection and cervical cells was collected for detection of HPV DNA of 36 types at study entry and at 6 consecutive 6-month follow-up visits...

Data on the incidence and determinants of human papillomavirus (HPV) infection in women >30 years old are scarce. To address this, a cohort of 1610 women--15-85 years old, HPV negative, and with normal cytological results at baseline--was monitored every 6 months for an average of 4.1 years. Information on risk factors and cervical samples for cytological testing and detection and typing of HPV DNA were obtained at each visit. The incidence of high-risk types was higher than that of low-risk types (5.0 vs...

OBJECTIVES: This study describes the clinical, epidemiological and microbiological characteristics of adult patients with blood cancer and neutropenic enterocolitis treated in the Instituto Nacional de Cancerologia (National Cancer Institute) in Bogota, Colombia. METHODS: The clinical histories of 692 adult patients hospitalized in the Instituto Nacional de Cancerologia between 1997 and 2001 with a diagnosis of leukemia or lymphoma were reviewed. Thirty-five of these cases met the criteria for probable or confirmed neutropenic enterocolitis...

In view of the important clinicopathologic, evolutional, and ultrastructural characteristics of dermatofibrosarcoma Protuberans, a review was made of 30 patients seen during the last 25 years in Colombia's Instituto Nacional de Cancerologia. The incidence is low, accounting for 0.06% of all malignant tumors and 1.17% of all soft-parts sarcomas. The series comprises 19 women and 11 men, with the highest incidence found between ages of 30 and 50 years, although the study includes two children, ages 8 and 13. The chest was the most common site...
