Modeling individual and relative accuracy of screening tools in geriatric oncology.

Classification probabilities reflect to what degree a screening test represents the true disease state and include true positive (TPF) and false positive fractions (FPF). With two tests, one can compare TPF and FPF using relative probabilities which offer advantages in terms of interpretation and statistical modeling. Our objective was to highlight how individual and relative TPF and FPF can be easily estimated and compared within a regression modeling framework. This allows the modeling of tests' accuracy while adjusting for multiple covariates, and thus provides valuable information in addition to the crude TPF and FPF. We illustrate our purpose with the G8 and VES-13 screening tests aimed at identifying elderly cancer patients in need for a comprehensive geriatric assessment (CGA).

Predictive parameters for imatinib failure in patients with chronic myeloid leukemia.

Until recently, imatinib was the standard first-line treatment in chronic myeloid leukemia (CML). The inclusion of nilotinib and dasatinib as first-line options in CML raised a debate on treatment selection. The aim of our study was to analyze predictive parameters for imatinib response as the first-line treatment of CML patients.

Osteopontin: its potential role in cancer of children and young adults.

Osteopontin (OPN) is aglyco-phosphoprotein, involved in tissue remodeling, inflammation and boneresorption. In various adult neoplasms OPN was shown to correlate with cancer progression, invasiveness and metastasis.

Carcionoid of the appendix in pregnant woman - case report and literature review.

Neuroendocrine neoplasms are detected very rarely in pregnant women. The following is a case report of carcinoid tumor of the appendix diagnosed in 28 year-old woman at 25th week of gestation. The woman delivered spontaneously a healthy baby at the 38th week of gestation. She did not require adjuvant therapy with somatostatin analogues. The patient remained in remission. There are not established standards of care due to the very rare incidence of carcinoid tumors in pregnancy. A review of the literature related to management and prognosis in such cases was done.

Tissue expression of human epididymal secretory protein 4 may be useful in the differential diagnosis of uterine cervical tumors.

Human Epididymal Secretory Protein 4 was firstly described as an epididymis-specific protein but more recently it has been demonstrated to be a putative serum tumor marker for different malignancies, especially ovarian epithelial cancers. The aim of this study is to investigate the association between tissue Human Epididymal Secretory Protein 4 expression and the clinicopathological features of uterine cervical tumors.

Application of Electronic Algorithms to Improve Diagnostic Evaluation for Bladder Cancer.

Strategies to ensure timely diagnostic evaluation of hematuria are needed to reduce delays in bladder cancer diagnosis.

New evidence of the relative protective effects of neurodegenerative diseases and cancer against each other.

Cancer and degenerative diseases share some pathogenic mechanisms which act in opposition to one another to produce either uncontrolled cell proliferation or cell death. According to several studies, patients with Alzheimer disease have a lower risk of neoplasia, and vice versa. This study describes the prevalence of tumours (active or successfully treated) in a series of patients with and without a dementing degenerative disease treated at a cognitive neurology unit.

Determining the epidemiologic, outcome, and prognostic factors of oral malignant melanoma by using the Surveillance, Epidemiology, and End Results database.

The authors conducted a retrospective analysis to determine the epidemiologic, outcome, and prognostic factors in patients with oral malignant melanoma (OMM).

Imaging of Subdural Hematomas.

The imaging of subdural hematoma has evolved significantly. Computed tomography and MRI have supplanted other procedures and rendered most obsolete for the evaluation of intracranial pathology because of ease of use, tremendous soft tissue resolution, safety, and availability. Noncontrast computed tomography has become the accepted standard of care for the initial evaluation of patients with suspected subdural hematoma because of widespread availability, rapid acquisition time, and noninvasive nature. MRI offers important features in determining potential secondary causes of subdural hematoma, such as dural-based neoplasms.

Patterns of distribution of giant congenital melanocytic nevi (GCMN): The 6B rule.

Garment-related terms have been used to describe the pattern of distribution of giant congenital melanocytic nevi (GCMN).

Solitary plasmacytoma associated with Epstein-Barr virus: a clinicopathologic, cytogenetic study and literature review.

Solitary plasmacytoma (SP) is an uncommon, indolent tumor of plasma cell neoplasms that presents as a mass lesion in extramedullary sites. Evidence of Epstein-Barr virus (EBV) infection is frequently associated with various lymphatic and hematopoietic malignancies but is relatively rare in SP. Moreover, it is essential to distinguish EBV-positive plasmacytoma from plasmablastic lymphoma. In this study, we found 4 EBV-encoded RNA (EBER)-positive patients among 46 consecutive immunocompetent patients of SP and compared the clinicopathologic features of these patients with those of the EBER-negative cohort. In the 4 EBER-positive patients, the common presenting feature was a local mass lesion without symptoms of chronic active EBV infection. Upon histologic examination, neoplastic cells demonstrated well-differentiated morphology in the absence of plasmablastic lymphoma components. Fluorescence in situ hybridization analysis showed that all cases were negative for del13q14, t(11;14)(q13;32) and MYC rearrangement but that 1 case had cytogenetic aberrations involving del17p13. Follow-up data revealed that EBER-positive patients had benign prognoses without aggressive clinical course and that there was no significant difference in the overall survival time between the 2 groups, but EBER-positive patients were more likely to have disease progression (relapse/progression to multiple myeloma) compared with EBER-negative patients. More case studies are needed to better understand the impact of EBV on disease pathogenesis and development in immunocompetent patients of SP.

Gastric Neoplasms.

Multimodality Treatment of Gastric Lymphoma.

Gastric lymphoma is rare, accounting for 3% of gastric neoplasms and 10% of lymphomas. Treatment should be stratified based on histologic type, stage, Helicobacter pylori infection, and t(11;18) translocation status. Surgery is no longer a mainstay for treatment and should be reserved for rare situations such as perforation, fistula formation, and severe bleeding. Multimodal treatment, including H pylori eradication, radiation therapy, chemotherapy, and immunotherapy, should be provided as appropriate and can result in excellent outcomes.

Endoscopic Management of Early Gastric Adenocarcinoma and Preinvasive Gastric Lesions.

Early gastric cancer (ECG) can be difficult to diagnose endoscopically. Endoscopists should be familiar with subtle changes and endoscopic features of EGC. Chromoendoscopy and image-enhanced endoscopy improve diagnostic accuracy and facilitate endoscopic resection. Endoscopic submucosal dissection is a preferred endoscopic technique for resection of EGC and offers a comparable overall survival to surgical resection. Endoscopic management of benign gastric epithelial polyps (fundic gland polyps, hyperplastic polyps, and gastric adenoma) depends on patient symptomatology, patient's comorbidities (eg, familial syndromes), lesions' characteristics, and risk of malignant transformation. This article provides an overview of endoscopic management of EGC and common premalignant gastric lesions.

Surveillance for Gastric Cancer.

This article discusses the current National Comprehensive Cancer Network guidelines and other available Western and Eastern guidelines for the surveillance of gastric cancer following surgical resection. It reviews the literature assessing the utility of intensive surveillance strategies for gastric cancer, which fails to show an improvement in survival. The unique issues relating to follow-up of early gastric cancer and after endoscopic resection of early gastric cancer are discussed. This article also reviews the available modalities for follow-up. In addition, it briefly discusses the advancements in treatment of recurrent and metastatic disease and the implications for gastric cancer survival and surveillance strategies.

Travelling for treatment; does distance and deprivation affect travel for intensity-modulated radiotherapy in the rural setting for head and neck cancer?

NHS England has commissioned intensity-modulated radiotherapy for head and neck cancers from Newcastle hospitals for patients in North Cumbria. This study assessed whether travel distances affected the decision to travel to Newcastle (to receive intensity-modulated radiotherapy) or Carlisle (to receive conformal radiotherapy).

Physical symptoms and working performance in female breast cancer survivors: a systematic review.

The aim of this systematic review was to summarize and systematize the information about physical symptoms and its relation with work activity on female Breast Cancer Survivors (BCS).

Lobectomy for lung cancer by video-assisted thoracic surgery in situs inversus.

A 62-year-old man with situs inversus totalis and non-small-cell lung cancer underwent a right lower lobectomy by video-assisted thoracoscopic surgery. Lobectomy in a situs inversus totalis patient can be performed safely using this minimally invasive procedure. Preoperative evaluation of the pulmonary artery and veins by three-dimensional computed tomography and the bronchial tree by bronchoscopy, is essential to avoid unanticipated complications during the procedure.

Methylation changes of SIRT1, KLF4, DAPK1 and SPG20 in B-lymphocytes derived from follicular and diffuse large B-cell lymphoma.

Diffuse large-B cell lymphomas (DLBCL) and follicular lymphomas (FL) are the most represented subtypes among mature B-cell neoplasms and originate from malignant B lymphocytes. Methylation represents one of the major epigenetic mechanisms of gene regulation. Silent information regulator 1 (SIRT1) is a class III lysine-deacetylase playing several functions and considered to be a context-dependent tumor promoter. We present the quantitative methylation, gene expression and tissue distribution of SIRT1 and some key mediators related to lymphoma pathogenesis in B lymphocytes purified from biopsies of follicular hyperplasias, FL and DLBCL. SIRT1 mRNA levels are higher in FL than follicular hyperplasias and DLBCL. B cell lymphoma 6 (BCL6) positively correlates with SIRT1. SIRT1 promoter shows a methylation decrease in the order: follicular hyperplasia - FL - DLBCL. Kruppel-like factor 4 (KLF4), Death-associated protein kinase 1 (DAPK1) and Spastic Paraplegia 20 (SPG20) methylation increase significantly in FL and DLBCL compared to follicular hyperplasias. Gene expression of DAPK1 and SPG20 inversely correlates with their degree of methylation. Our findings evidence a positive correlation between SIRT1 and BCL6 expression increase in FL. SIRT1 methylation decreases in FL and DLBCL accordingly and this parallels the increase of KLF4, DAPK1 and SPG20 methylation.

Prolymphocytic Leukemia: New Insights in Diagnosis and in Treatment.

We aimed to produce a comprehensive update on clinical and biological data regarding two rare lymphoid neoplasms, B and T prolymphocytic leukemias, and assess therapeutic management in the light of new molecular insights and the advent of targeted therapies.

Chemotherapy-induced irreversible alopecia in early breast cancer patients.

The purpose of this work is to determine the prevalence of chemotherapy-induced irreversible alopecia (CIIA), which is defined as an alopecia that exists at least 6 months after completion of chemotherapy and factors affecting CIIA in early breast cancer patients.

GATA3 and MYB Expression in Cutaneous Adnexal Neoplasms.

Knowledge of staining pattern of certain immunostains might be useful in the classification of cutaneous adnexal tumors that can have clinical importance. We studied GATA3 and MYB expression in archival materials of 220 adnexal tumors comprised of sebaceous carcinomas, follicular tumors, apocrine carcinoma, predominantly apocrine tumors, predominantly eccrine tumors, and others including adenoid cystic carcinomas. Nuclear GATA3 expression was seen in 70% (153/220) of cases, including sebaceous carcinoma (93%), apocrine carcinoma (93%), follicular neoplasms (100%), and predominantly apocrine neoplasms (69%), yet only 38% of predominantly eccrine neoplasms. Nuclear MYB expression was seen in 43% (81/188) of cases, including adenoid cystic carcinoma (90%), predominantly apocrine tumors (66%), follicular neoplasms (49%), apocrine carcinomas (14%), predominantly eccrine tumors (11%), and sebaceous carcinomas (4%). GATA3 and MYB expression were noted in 43% (9/21) and 24% (5/21) of cutaneous metastases, respectively. Expression of both GATA3 and MYB was noted in 33% (60/184) of primary adnexal tumors versus 19% (4/21) of cutaneous metastases. GATA3 preferentially labels tumors with follicular, sebaceous, and apocrine differentiation. MYB is potentially a helpful stain in the distinction of desmoplastic trichoepithelioma versus basal cell carcinoma. The coexpression of GATA3 and MYB might be helpful in the distinction of primary cutaneous adnexal carcinoma versus metastatic breast, salivary gland, or urothelial carcinoma.

Squared-Off Nuclei and "Appliqué" Pattern as a Histopathological Clue to Periocular Sebaceous Carcinoma: A Clinicopathological Study of 50 Neoplasms From 46 Patients.

The histopathological diagnosis of periocular sebaceous carcinoma can be difficult in poorly differentiated cases showing few mature sebocytes. The authors examined 50 periocular sebaceous carcinomas from 46 patients to determine the frequency of 2 features seen in this neoplasm, namely cells with squared-off nuclei and so-called "appliqué" pattern (peritumoral subnecrosis of peripherally located neoplastic cells). Neoplastic cells with squared-off nuclei were found in varying numbers in both the intraepithelial and dermal (invasive) components in all neoplasms, whereas the appliqué pattern was observed in a third of the cases. It is concluded that these features, taken together, may serve as a clue for the diagnosis of periocular sebaceous carcinoma.
