cfDNA fragmentation patterns correlate with tumor burden measured via PSMA PET/CT volumetric parameters in patients with biochemical recurrence of prostate cancer.

Background: Prostate cancer recurrence following primary treatment poses a significant clinical challenge, particularly when detected through biochemical recurrence at low PSA levels. Conventional imaging modalities often fail to localize the disease at this early stage. PSMA PET has demonstrated superior sensitivity in detecting recurrent lesions, even in patients with low PSA.

Clinical characteristics and HPV type in recurrent respiratory papillomatosis in Colombia.

Objective: Describe factors associated with aggressive forms of recurrent respiratory papillomatosis (RRP).

Materials And Methods: One hundred eighty-nine RRP cases diagnosed between 1985 and 2009 were identified in pathological records. HPV was detected by the SPF-10 method with broad spectrum primers, (version 1).

Human papillomavirus types in cases of squamous cell carcinoma of head and neck in Colombia.

Unlabelled: Estimating the type-specific prevalence of human papillomavirus (HPV) in head and neck cancer (HNSCC) is helpful in predicting the impact of HPV immunization.

Objective: To estimate the overall prevalence, and gender and age-specific prevalence of HPV in HNSCC.

Method: This cross sectional retrospective study was carried out in four pathology laboratories of Medellin, Colombia.

Human papillomavirus genotype detection in recurrent respiratory papillomatosis (RRP) in Colombia.

Background: Knowledge on human papillomavirus (HPV) genotype distribution in recurrent respiratory papillomatosis (RRP) is essential to assess the impact of HPV vaccine. It is provided information for Colombia.

Methods: In all, 189 RRP primary cases diagnosed between 1985 and 2009 were identified from 5 pathology laboratories of Cali and Medellin, Colombia.

[Trends and social indicators of both mortality breast cancer and cervical cancer in Antioquia, Colombia, 2000-2007].

Objective: To estimate the mortality age-standardized rates (ASR) for breast and cervical cancer from 2000-2007 and explore social indicators that explain the variability of rates in Antioquia.

Material And Methods: The ASR was estimated by the direct method and linear regression was used to relate social indicators with rates by subregion.

Results: Breast and cervical cancer mortality ASRs in Antioquia were 11.
