1. An easy and practical prognostic parameter: tumor–stroma ratio in Luminal, Her2, and triple-negative breast cancers
SUMMARY OBJECTIVE: The stroma surrounding the tumor cells is important in tumor progression and treatment resistance, besides the properties of tumor cells. Studies on the tumor stroma characteristics will contribute to the knowledge for new treatment approaches. METHODS: A total of 363 breast cancer patients were evaluated for the tumor–stroma ratio. Th

2. Ozone combined with doxorubicin exerts cytotoxic and anticancer effects on Luminal-A subtype human breast cancer cell line
SUMMARY OBJECTIVE: We aimed to examine the potential anticancer effects of ozone applied after chemotherapeutic treatment with different concentrations of doxorubicin in Luminal-A subtype of human breast cancer cell line (MCF-7) and compare the results with effects on L929 fibroblast cell line. METHODS: Both cell lines were incubated with increasing doses

3. Prognostic assessment of tumor markers in lung carcinomas
SUMMARY BACKGROUND: Serum tumor markers are molecules that are secreted by tumor cells and may be present in small amounts in the serum of healthy individuals. Their role as prognostic factors in lung cancer remains controversial. OBJECTIVE: To assess the prognostic role of CEA, CA 19-9, CA 15-3, and CA 125 in non-squamous non-small cell lung cancer. PATI

4. CD45RO+TILs: cellular biomarkers for larynx squamous cell carcinoma outcome
Abstract Objective: The prognostic importance of Tumor-Infiltrating Lymphocytes (TILs) in the tumor microenvironment of various cancers is increasingly recognized. In the present study, we aimed to investigate the prognostic value of CD3+, CD4+, CD8+, and CD45RO + TILs and their relation to histopathological features in larynx squamous cell carcinoma. Meth

5. Scanning electron microscopy of panitumumab-induced eyelash and hair alterations - Pili canaliculi
Abstract Panitumumab is a monoclonal antibody against the epidermal growth factor receptor used in metastatic colorectal cancer; in addition to tumor cells, it acts on epidermal keratinocytes and on the outer root sheath and presents skin toxicity in up to 90% of cases. A scanning electron microscope was used to examine the eyelashes and hairs of a 65-year-o

6. Tumorigenic and immunological roles of Heat shock protein A2 in pancreatic cancer: a bioinformatics analysis
SUMMARY OBJECTIVE: Heat shock protein A2 has been reported to be tightly associated with tumorigenesis and tumor progression. This study aimed to determine the oncogenic and immunological roles of Heat shock protein A2 in pancreatic cancer by bioinformatics. METHODS: Expression of Heat shock protein A2 in tumorous and normal specimens of pancreatic cancer

7. Extracranial non-vestibular head and neck schwannomas: a case series with the review of literature
Abstract Introduction: Schwannomas are tumous that arise from Schwann cells. Schwannoma is one of the differential diagnosis for lateral neck swelling. Objective: In this study, we aim to describe the incidence, presenting clinical features and management of extracranial, non-vestibular schwannomas of head and neck region, along with the review of the lite

8. Non-alpine primary thyroid angiosarcoma
SUMMARY Thyroid angiosarcoma is an extremely rare malignancy, which occurs more frequently in the alpine region, likely associated with iodine deficiency and endemic goiter. This is an aggressive neoplasm that usually harbors a poor prognosis. We report the case of a 49-year-old Portuguese female patient presenting with a large nodule in the anterior neck re

9. Association of 25-hydroxyvitamin D with hematological profile and anthropometry in patients with glioma
SUMMARY OBJECTIVE: Gliomas are immune system suppressive tumors, and the role of vitamin D is pivotal in the immune system. This study aimed to observe if there is any significant association between the serum levels of 25-hydroxyvitamin D with hematological indices and anthropometric measurements. METHODS: A total of 75 glioma patients were included, and

10. Enhanced serum interferon-lambda 1/interleukin-29 levels in patients with psoriasis vulgaris
Abstract Background: Interferon (IFN)-λ1, also named Interleukin (IL)-29, is a new member of the Type III IFN or IFN-λ family. IL-29 plays an important role in the pathogenesis of many types of autoimmune and inflammatory diseases. Objective: To study the role of IL-29 in the pathogenesis of psoriasis vulgaris. Methods: The authors detected the serum le

11. Semen quality from patients affected by seminomatous and non-seminomatous testicular tumor
ABSTRACT Testicular cancer is considered a rare disease affecting approximately 1% to 2% of the male population. This neoplasm has a cure rate of over 95%; as a result, a major concern is the future of fertility of carriers from this disease. There are several histological subtypes of testicular tumors; however, the Testicular Germ Cell Tumors (TGCTs), compr

12. Ultraconserved long non-coding RNA uc.112 is highly expressed in childhood T versus B-cell acute lymphoblastic leukemia
ABSTRACT Aberrant expression of long non-coding RNAs (lncRNAs) has been detected in several types of cancer, including acute lymphoblastic leukemia (ALL), but lncRNA mapped on transcribed ultraconserved regions (T-UCRs) are little explored. The T-UCRs uc.112, uc.122, uc.160 and uc.262 were evaluated by quantitative real-time PCR in bone marrow samples from c
