Objective: To evaluate the frequency distribution of viral infections in Peruvian Breast Cancer (BC) lesions and its association with clinicopathological features. Additionally, a prospective evaluation of p16 and Tumor-infiltrating lymphocytes (TIL) levels were performed for developing a comprehensive analysis. Methods: Detection of high risk- human papillomavirus (HR- HPV) through qPCR was performed in 447 BC and 79 non-cancer frozen samples. Paired paraffin samples from 238 BC were stained with Human cytomegalovirus (HCMV) and p16 immunohistochemistry. TIL was calculated in 397 BC cases. Results: HCMV was positive in 72.5%. HR- HPV was detected in 2.9% of BC and 1.3% of non-malignant samples. P16+ was found in 28.15% and median TIL percentage was 30. HR- HPV infection was associated with non-ductal histology (p=0.003) and p16+ (p=0.017). Positive P16+ was associated with higher T stag...

Circulating tumor DNA (ctDNA) evaluates cellular components of cancer cells in plasma. Breast cancer (BC) is the most frequent one. Studying ctDNA is a non-invasive method to assess BC. Patients with BC have higher levels of ctDNA than those without. High ctDNA levels are more frequent in patients with metastatic disease with high tumor burden and with more aggressive disease, such as those with triple-negative phenotype and HER2+. ctDNA allows the selection of target treatment for metastatic disease. Elimination of ctDNA during neoadjuvant chemotherapy in early BC is associated with higher complete response rates and longer survival and also predicts relapses well in advance.

We report four cases of glioblastoma in the pineal region. The patients presented a severe headache and vomiting. Brain imaging showed a heterogeneously enhanced tumor in the pineal region with obstructive hydrocephalus. Case 3 developed a subependymal dissemination. The patient went to ventricular-peritoneal shunt and subtotal or total resection and radiotherapy with/without chemotherapy. Cases 1 and 2 received radiation and died 8 and 11 later months. Cases 3 and 4 completed radiotherapy and chemotherapy, and survived 28 and 31 months after the initial diagnosis. Glioblastoma in the pineal region carry a poor prognosis and require neurooncology teams.

Molecular analysis of human biological material allows the identification of future biomarkers to improve the management of patients with cancer. However, the handling of these samples requires particular ethical considerations. Different organizations such as the European Council and government agencies of the United States have generated different documents with definitions, mechanisms, and regulations to avoid putting at risk of harm or violating the rights of donors of biological samples. Finally, all these documents have evolved over time and have allowed research institutions to have standard committees and regulations in ethics. Thus, legal institutions can create precedents and generate coherent sentences.

Tuberculosis (TB) is a major public health problem that, due to the clinical variability of its presentation, can be confused with cancer. The aim of this study was to identify the clinical-radiological characteristics and to describe the methodology that allowed to achieve a TB diagnosis in patients referred to the National Institute of Neoplastic Diseases (INEN) with a presumed diagnosis of cancer between 2014 and 2016. The study included 170 patients (52.4% men) with an average age of 41.1 years; 18% presented a history of contact with TB, and 5.9% had had the disease previously. The TB was pulmonary in 22.4% and extrapulmonary in 77.7% of patients. The most frequent symptoms were respiratory, tumor, weight loss, and neurological. The cancer diagnoses most frequently discarded were lymphoma, lung cancer, and brain cancer. The lesions that suggested a neoplasm indicated an advanced cli...

Around 2% of early breast cancer cases treated with axillary lymph node dissection (ALND) underwent axillary recurrence (AR) and it has a deleterious effect in prognosis. Different scenarios have incorporated Sentinel Lymph Node (SLN) Biopsy (SLNB) instead of ALND as part of the standard treatment and more effective systemic treatment has also been incorporated in routine management after first curative surgery and after regional recurrence. However, there is concern about the effect of SLNB alone over AR risk and how to predict and treat AR. SLN biopsy (SLNB) has been largely accepted as a valid option for SLN-negative cases, and recent prospective studies have demonstrated that it is also safe for some SLN-positive cases and both scenarios carry low AR rates. Different studies have identified clinicopathological factors related to aggressiveness as well as high-risk molecular signature...

Aim: This retrospective study determined features associated with brain metastasis (BM) in women with breast cancer. Patients & methods: A total of 215 initially early breast cancer cases were included. We reviewed files and CT scan images of BM. Results: Median age was 47 years and most of our cases were stage III (58.6%), grade III (62.8%), ER negative (62.3%) and nonluminal (59.1%). Median survival after BM was 4 months. Nonluminal, extracranial disease, time to CNS shorter than 15 months, >three brain lesions and poor breast-graded prognostic assessment and recursive partitioning analysis scores were associated with shorter survival. Adding extracranial disease to breast-graded prognostic assessment score also predicted survival after BM. Radiation response was assessed in 57 patients and response tended to be associated with nonluminal phenotype but not with survival. Conclusion: Fa...

AIM:To investigate clinicopathological features and biomarkers of BC tumors in males and their prognostic value in Peruvian population. METHODS: This study looked at a single-institution series of 54 Peruvian males with invasive BC who were diagnosed from Jan 2004 to June 2018. Standard pathological features, TIL levels, MMR proteins, AR immunohistochemistry staining, and PIK3CA gene mutations were prospectively evaluated in cases with available paraffin material. Percentage of AR and estrogen receptor (ER) positive cells was additionally calculated by software after slide scanning. Statistical analyses included association tests, intraclass correlation test and Kaplan Meier overall survival curves. RESULTS: The median age was 63 years and most cases were ER-positive (85.7%), HER2 negative (87.2%), Luminal-A phenotype (60%) and clinical stage II (41.5%) among our male breast tumors. Medi...

Purpose: Helicobacter pylori (HP) and Epstein Barr virus (EBV) infections induce chronic gastritis (CG) and are accepted carcinogenics of gastric cancer (GC). Our objective for this study was to determine the prevalence of these agents and clinicopathological features of GC and CG associated with the infection. Patients and methods: A single-center cohort of 375 Peruvian patients with GC and 165 control subjects with CG were analyzed. Evaluation of HP and EBV genes was performed through quantitative polymerase chain reaction. Results: Prevalence of HP was 62.9% in the whole population and 60.8% in the GC subset. The cagA gene was detected in 79.9%; vacAs1 and vacAm1 alleles in 41.6% and 60.7%, respectively; and concurrent expression of vacAs1 and vacAm1 in 30.4% of infected patients in the whole series. The prevalence of EBV was 14.1% in the whole population and was higher in GC (P < .00...

Aim: Evaluation of features related to infiltrating immune cell level in glioblastoma. Methods: Tumor-infiltrating lymphocytes (TILs) through H&E staining, and TILs (CD3, CD4, CD8 and CD20) and macrophage (CD68 and CD163) levels through immunohistochemistry were evaluated through digital analysis. Results: CD68 (9.1%), CD163 (2.2%), CD3 (1.6%) and CD8 (1.6%) had the highest density. Higher CD4+ was associated with unmethylated MGMT (p = 0.016). Higher CD8+ was associated with larger tumoral size (p = 0.027). Higher CD163+ was associated with higher age (p = 0.044) and recursive partitioning analysis = 4. Women (p < 0.05), total resection (p < 0.05), MGMT-methylation (p < 0.001), radiotherapy (p < 0.001), chemotherapy (p < 0.001) and lower CD4+ (p < 0.05) were associated with longer overall survival. Conclusion: Macrophages are more frequent than TILs. Some subsets are associated with cli...
