To Investigate Outcomes In Endoscopic Management Of Early Oesophageal Adenocarcinoma In Barrett's Oesophagus: Experience At Three Australian Tertiary Centres.Barrett's oesophagus (BO) is known precursor of oesophageal adenocarcinoma (EAC). Early EAC includes T1a (invasion into mucosa) and T1b (invasion into submucosa but not muscularis propria). Endoscopic mucosal resection (EMR) provides accurate histological staging and definitive treatment for early EAC. Post EMR, the remaining Barrett's is eradicated with radiofrequency ablation (RFA). However, there is a paucity of long-term Australian data.

miR-3613-5p enhances the metastasis of pancreatic cancer by targeting CDK6.Pancreatic cancer (PC) is a leading cause of cancer mortality and is expected to continue increasing incidence. Abnormally expressed microRNAs have been demonstrated tightly correlated with the development and progression of PC. However, the molecular mechanisms remain largely unknown. In this study through combing both the TCGA database and our two verification PC cohorts, we found the consistent reduction of miR-3613-5p in PC tumors, which significantly correlated with reduced cumulative survival rate among PC patients. PC patients with higher lymph node metastasis rate show reduced miR-3613-5p expression. Through further mechanistic investigation, we demonstrate that miR-3613-5p down-regulated CDK6 in repressing the metastasis capacity of PC cells and . Elevated CDK6 were also found in PC samples, which also correlate with poor prognosis. Thus, our study found a novel tumor repressor miR-3613-5p in PC progression.

The expression of p16 and galectin-3 in cervical intraepithelial neoplasia (CIN) and squamous cell carcinoma (SCC) uterine cervix.Cervical cancer is the most prevalent cancer among women in India. The main cause of cervical cancer is persistent human papilloma viral (HPV) infection. HPV inactivates the pRb tumour suppressor protein; thus p16 expression, which is controlled by a negative feedback mechanism, is relatively increased. Galectin-3 is directly and indirectly connected to cancer cell activity and contributes to oncogenesis, angiogenesis, cancer progression and metastasis. Thus, the aim of this study was to study the expression of p16 and galectin-3 in Cervical Intraepithelial Neoplasia (CIN) and Squamous Cell Carcinoma (SCC) and to correlate p16 and galectin-3 expression. On hundred and eighteen newly-diagnosed untreated cases of CIN and SCC of uterine cervix were included in the study. Expression of p16 and galectin 3 was more pronounced in invasive SCC and High-grade Intraepithelial Lesion (HSIL), as compared to Low-grade Intraepithelial Lesion (LSIL).Thus, it may be used in clinical setting to monitor cervical lesions and to predict their progression. Impact statement p16 overexpression is a surrogate biomarker of HPV infection and useful in evaluating HPV-associated squamous and glandular neoplasia of the lower gynaecologic tract. Increased galectin-3 expression is seen in SCC cervical, with less consistent results in CIN. The results of our study adds to the growing literature that p16 and galectin-3 expression have direct statistically significant correlation with a degree of dysplasia and SCC cervix. Expression of p16 and galectin-3 was more pronounced in invasive SCC and high-grade intraepithelial lesion (HSIL), as compared to low-grade intraepithelial lesion (LSIL). This correction of p16 and galectin-3 expression with degree of dysplasia and SCC cervix can be used for screening and early detection of cervical lesions and thus aid their early treatment and increased survival.

Herbal and Natural Dietary Products: Upcoming Therapeutic Approach for Prevention and Treatment of Hepatocellular Carcinoma.The most common tumor linked with elevated death rates is considered the hepatocellular carcinoma (HCC), sometimes called the malignant hepatoma. The initiation and progression of HCC are triggered by multiple factors like long term alcohol consumption, metabolic disorders, fatty liver disease, hepatitis B and C infection, age, and oxidative stress. Sorafenib is the merely US Food and Drug Administration (FDA)-approved drug used to treat HCC. Several treatment methods are available for HCC therapy such as chemotherapy, immunotherapy and adjuvant therapy but they often lead to several side effects. Yet these treatment methods are not entirely adequate due to the increasing resistance to the drug and their toxicity. Many natural products help to prevent and treat HCC. A variety of pathways are associated with the prevention and treatment of HCC with herbal products and their active components. Accumulating research shows that certain natural dietary compounds are possible source of hepatic cancer prevention and treatments, such as black currant, strawberries, plum, grapes, pomegranate, cruciferous crops, tomatoes, French beans, turmeric, garlic, ginger, asparagus, and many more. Such a dietary natural products and their active constituents may prevent the production and advancement of liver cancer in many ways such as guarding against liver carcinogens, improving the effectiveness of chemotherapeutic medications, inhibiting the growth, metastasis of tumor cells, reducing oxidative stress, and chronic inflammation. The present review article represents hepatic carcinoma etiology, role of herbal products, their active constituents, and dietary natural products for the prevention and treatment of HCC along with their possible mechanisms of action.

Liquid biopsy and their application progress in head and neck cancer: focus on biomarkers CTCs, cfDNA, ctDNA and EVs.Head and neck cancer (HNC) is the sixth leading cause of cancer death worldwide. Due to the low early diagnosis rate of HNC, local recurrence and high distant metastasis rate are the main reasons for treatment failure. Therefore, it is important to establish a method of diagnosis and monitoring, which is convenient, safe, reproducible, sensitive and specific. Compared with tissue biopsy, liquid biopsy is an emerging biopsy technique, which has the advantages of re-sampling, noninvasive, cost-effective and has shown good diagnostic and prognostic value in studies for various types of malignant solid tumors. This review introduces liquid biopsy, its research progress and prospects in HNC including early diagnosis, staging, grading, prognosis assessment and disease surveillance.

MRI-based predictive factors of axillary lymph node status in breast cancer.To evaluate the diagnostic value of diffusion-weighted imaging (DWI) in combination with conventional MRI in predicting metastatic axillary lymph nodes (ALN) in breast cancer (BC). We reviewed pathological findings and clinical breast MRI examinations of 169 patients with invasive BC who were evaluated at the Hôtel-Dieu de France Hospital in 2009-2015. Morphological parameters and apparent diffusion coefficient (ADC) value were compared with pathological nodal status. Independent t-test/chi-square test and a Pearson correlation analysis were used. With pathological diagnosis as reference, MRI-based interpretations were 87.5% specific and 70.3% sensitive. On conventional MRI, the round shape of lymph nodes (LNs), loss of fatty hilum, irregular margins and hypo-intensity/heterogeneous intensity on T2-weighted sequence were statistically significantly different between metastatic and nonmetastatic groups (P < .001, each). Mean size of metastatic ALN was larger compared with negative ALN (13.9 mm vs. 10.9 mm, P < .001). LNs ≥ 12 mm were associated with higher risk of metastasis (P < .001). ADC value was not significantly different between both groups (P = .862). Conventional MRI using the ALN shape, signal intensity in T2-weighted sequences, loss of fatty hilum, regularity of the margins and size of the LNs can evaluate the axilla with high specificity. ADC value could not be used as a reliable parameter.

Expression of IMP3 in A Retrospective Cohort of Melanomas With Selective Lymph Node Biopsy.Insulin-like growth factor-II mRNA-binding protein 3 (IMP-3), which is a member of the insulin-like growth factor mRNA-binding protein family, is expressed at high levels in many types of cancer, where it plays an important role in cell proliferation, as well as in the processes of invasion, migration and metastasis. Its expression has also been demonstrated in malignant melanoma, but not in other benign skin lesions, which has raised the possibility of using it as a predictive and prognosis marker. Its relationship with sentinel lymph node biopsy, however, has not been explored yet. A retrospective study including 120 histological samples of patients diagnosed with malignant cutaneous melanoma in Granada, between 2012 and 2018, was developed. All patients had had a sentinel lymph node biopsy (SLNB) performed at Hospital Universitario San Cecilio. IMP3 immunostaining was simultaneously carried out in the cutaneous lesion. We observed a significant difference regarding the percentage of cells expressing IMP3 (29.73 ± 3.81 for negative SLNB vs 44.86 ± 5.91 for positive SLNB, P = 0.020). Our endpoint calculated according to the ROC curve of 35% was significant with P = 0.007. H (P = 0.013) and AR (P = 0.016) indexes, created by the percentage of positive tumour cells and the intensity of the IMP3 expression, were also statistically significant. The most optimal cut-off points to predict the positivity of the SLNB were 35 for the percentage of positive tumour cells and 70 for the H score. We found a significant association between the expression of IMP3 and the regional nodal status defined by the SLNB on malignant melanomas in our series. This article is protected by copyright.

Fatal case of pancreatic panniculitis caused by occult neuroendocrine tumor in the corresponding organ: A case report and review of the published work.Pancreatic panniculitis (PP) is a rare clinical variant of subcutaneous fat necrosis, developing in patients with a variety of pancreatic diseases such as acute or chronic pancreatitis, tumors and cysts. The tumor-associated PP represents a noteworthy skin manifestation of underlying internal malignancies, also known as dermadrome. Among causative pancreatic tumors, acinar cell carcinoma is the most frequent malignancy; however, little is known about how the origin of tumor cells and progression stage of pancreatic tumors potentially contribute to the establishment of panniculitis. Here, we present a 69-year-old Japanese male case of clinically aggressive PP on the bilateral legs, whose skin lesions developed prior to the diagnosis of occult pancreatic tumor and liver metastasis. Moreover, the immunopathology of the pancreatic lesion revealed neuroendocrine tumor (NET), a rare pathological variant. Skin lesions immediately spread to the upper limbs with extensive ulcerations and necrosis, accompanied by high levels of serum lipase and elastase, but not with other pancreatic enzymes. He died 2 months after the initial development of the skin lesion due to rapid deterioration of general condition. We reviewed 14 cases, including ours, of PP with NET in the pancreas thus far reported, to identify the clinicopathological characteristics regarding to what extent this rare complication could reflect the clinical course of pancreatic tumors and overall prognosis. Our published work review found that the disease has a significant male predominance (male : female, 13:1) and cases with occult pancreatic tumors died within 4 months after the development of their skin lesions. Our case was the poorest prognostic outcome. This report emphasizes that dermatologists should recognize PP with NET, reflecting a fatal prognosis, and to make a prompt diagnosis.
