Obesity, a cause of subclinical inflammation, is a risk factor for the development of postmenopausal breast cancer (BC) and is associated with poorer cancer outcomes. Docosahexaenoic acid (DHA), an omega-3 fatty acid, possesses anti-inflammatory properties. We hypothesized that treatment with DHA would reduce the expression of proinflammatory genes and aromatase, the rate-limiting enzyme for estrogen biosynthesis, in benign breast tissue of overweight/obese women. A randomized, placebo-controlled, double-blind phase II study of DHA given for 12 weeks to overweight/obese women with a history of stage I-III BC, DCIS/LCIS, Paget's disease, or proliferative benign breast disease was carried out...

PURPOSE OF REVIEW: The purpose of this review is to summarize the management of serrated colorectal polyps (SPs), with a particular focus on the most common premalignant SP, sessile serrated adenoma or polyp (SSA/P). These lesions present a challenge for endoscopists with respect to detection and resection, and are also susceptible to pathologic misdiagnosis. RECENT FINDINGS: Patients with SSA/Ps are at an increased risk of future colorectal neoplasia, including advanced polyps and cancer...

Benign proliferations that mimic malignancies are commonly encountered during the course of assessment of small and fragmented endometrial samples. Although benign, endometrial epithelial metaplasias often coexist with premalignant or malignant lesions causing diagnostic confusion. The difficulty with mucinous metaplasia lies in its distinction from atypical mucinous glandular proliferations and mucinous carcinomas, which are associated with significant interobserver variability. Papillary proliferation of the endometrium is commonly associated with hormonal drugs and endometrial polyps and is characterised by papillae with fibrovascular cores covered by epithelial cells without cytologic atypia...

Several biomarkers are in use to improve the sensitivity and specificity of cervical cancer screening. Previously, increased expression of tight junction protein claudin-1 (CLDN1) was detected in premalignant and malignant cervical lesions and applied for cytology screening. To improve the specificity, a double immunoreaction with CLDN1/Ki67 was developed in the recent study. Parallel p16/Ki67 (CINtec® PLUS) and CLDN1/Ki67 dual-stained cytology and histology were performed and compared. p16/Ki67 immunoreaction showed positivity in 317 out of 1596 smears with negativity in 1072 and unacceptable reactions in 207 samples...

Oral leukoplakia (OL) is one of the most common oral precancerous lesions with the possibility of malignant transformation, ranging from 17 to 24% of patients with a median follow-up of >7 years. Previous research has revealed that compared with normal oral epithelial tissues, the expression of secretory leukocyte peptidase inhibitor (SLPI) protein is significantly reduced in oral squamous cell carcinoma (OSCC). Based on the above-mentioned research, it is known that SLPI is a potential predictive and diagnostic tool for the progression of oral carcinogenesis...

High-risk human papillomavirus (HPV) is the primary cause of cervical carcinoma (CC). Viral integration into the host chromosomes is associated with neoplastic progression, and epigenetic changes may occur as a result. The objective of the present study was to analyze HPV L1 gene methylation and to compare the use of quantitative polymerase chain reaction (qPCR), in situ hybridization (ISH) and L1 methylation analysis as methods for detecting HPV integration. Cervical scrapes or biopsy samples positive for HPV 16 or 18, from 187 female patients with CC, squamous intraepithelial lesions (SILs) or no intraepithelial lesion (non-IL) were analyzed...

Epithelial-to-mesenchymal transition (EMT) is organized in cancer cells by a set of key transcription factors, but the significance of this process is still debated including in non-small cell lung cancer (NSCLC). Here we report increased expression of the EMT-inducing transcription factor Snail in premalignant pulmonary lesions, relative to histologically normal pulmonary epithelium. In immortalized human pulmonary epithelial cells and isogenic derivatives, we documented Snail-dependent anchorage-independent growth in vitro and primary tumor growth and metastatic behavior in vivo...

Oral mucosal melanoma (OMM) is notorious for having a poor prognosis. Recognition of the early features of OMM by both clinicians and pathologists can play an important role in improving survival. Therefore, the purpose of this report is to increase awareness of the early features of OMM, by presenting 2 cases with longitudinal clinical and histopathologic documentation showing progression of OMM from a deceptively bland premalignant (noninvasive) oral melanocytic lesion (POML). By analyzing the clinical and histopathologic features of POML in our cases, and those in the literature, we found that the concerning features are (1) clinically, a pigmented lesion violating the ABCDE criteria or showing multiple recurrences; and (2) histologically, a melanocytic proliferation, in either a lentiginous or pagetoid pattern with or without cellular atypia...

Treatment of cervical premalignant lesions (cervical intraepithelial neoplasia; CIN) of different grades is very effective, simple, and safe. The entire transformation zone of the cervix needs to be treated either by an ablative technique (cryotherapy or thermal ablation) or an excisional technique (large loop excision of transformation zone or cold knife conization); the choice of treatment depends on the size and location of the lesion and the type of the transformation zone. The cure rate after ablative treatment of high-grade CIN may be little lower than that after excisional treatment...

OBJECTIVES: To develop an actionable test using fluorescence capillary electrophoresis (FCE) to assess loss of heterozygosity (LOH) of histologically similar low-grade lesions (LGLs) to identify high-risk lesions for oral cancer progression. STUDY DESIGN: To determine the cutoffs of LOH, the FCE results of 52 surgical margin samples were used to compare with the existing LOH results from the previously validated 32 P-GE approach. Using the developed FCE workflow, an independent set of 102 LGLs with known progression status was used to determine the LOH molecular risk (MR) patterns and associated risk of progression...

BACKGROUND: Patients with a history of colonic resection for cancer have an increased risk for the development of metachronous malignant lesions. However, there is a lack of data on the detection rates of premalignant lesions during colonoscopy surveillance in these patients, and the few existing studies have shown conflicting results. AIMS: To identify the risk factor of metachronous premalignant lesions after colon cancer surgery. METHODS: We retrospectively screened consecutive patients who had undergone colonic surgery to treat colon cancer at the Chungnam National University Hospital between September 2009 and April 2014...

OBJECTIVE: Oral cancer accounts for almost 40% of all cancers in the Indian subcontinent. Techniques like oral scrape cytology are helpful in early diagnosis of premalignant lesion and thus prevention of malignant transformation. The purpose of this study is to evaluate the performance of cytotechnologists in assessing the adequacy and preliminary diagnostic accuracy of oral brush liquid-based cytology. STUDY DESIGN: 110 oral brush liquid-based cytology smears were prospectively screened by a cytotechnologist for adequacy assessment, and a preliminary diagnosis was recorded...

Of the potentially (pre)maligant oral epithelial lesions, leukoplakia is the most common. A brief overview of the various definitions of leukoplakia that have been used in the past is presented here. A proposal has been made to modify the current definition. Clinically, for decades, leukoplakias have been divided into homogeneous and nonhomogeneous leukoplakias and further into different subtypes. A proposal has been made to slightly rearrange these subtypes. Furthermore, attention has been paid to a number of keratotic lesions that have been reported in the literature...

Cervical cancer continues to be a leading cancer among women in many parts of the world. Nation-wide screening with the Pap smear has not been implemented in India due to the lack of adequately trained cytologists. Identification of biomarkers to predict malignant potential of the identified low risk lesions is essential to avoid excessive retesting and follow up. The current study analyzed the expression patterns of DNA replication licensing proteins, proliferation inhibitor protein p16INK4A and tumor suppresser protein p63 in cervical tissues and smears to assess the ability of these proteins to predict progression...

Minimally-invasive techniques were adopted relatively late for pancreatic procedures due to their complexity. Today, minimally-invasive distal pancreatectomy is the procedure of choice for the treatment of benign or premalignant pancreatic lesions due to the advantages inherent to laparoscopy. Data on the efficacy of minimally-invasive distal pancreatectomy in oncologic surgery is still limited and larger prospective series are needed prior to its widespread use for the treatment of pancreatic cancer. This review addresses various aspects of distal pancreatectomy, with emphasis on recent developments and open controversies...

Use of drug combinations that target different pathways involved in the development and progression of prostate cancer (PCa) has emerged as an alternative to overcome the resistance caused by drug monotherapies. The antiandrogen abiraterone acetate and the PI3K/Akt inhibitor NVP-BEZ235 (BEZ235) may be suitable options for the prevention of drug resistance and the inhibition of PCa progression. The aim of the present study was to evaluate whether abiraterone acetate and BEZ235 achieve superior therapeutic effects to either drug administered as monotherapy, in the early stages of PCa in an androgen-dependent system...
