Background: Most pituitary neuroendocrine tumors (PitNET) show benign behavior, but a significant number are invasive, recur or resist to medical treatment. Based on a retrospective case-control study we recently proposed a classification of PitNETs of prognostic relevance. This prospective study aims to test the value of this classification in an independent patient cohort. Methods: The cohort included patients of a single center operated upon a PitNET. Using a grading system based on invasion on MRI, immunocytochemical profile (ICC), Ki-67, mitotic index, and p53 positivity, tumors were classified...

Background/Aims: Solitary hepatocellular carcinoma (HCC) is a subgroup of HCCs. We aimed to establish nomograms for predicting the survival of solitary HCC patients after hepatectomy. Methods: A total of 538 solitary HCC patients were randomly classified into training and validation sets. A Cox model was used to identify predictors of overall survival (OS) in the training set. A nomogram was generated based on these predictors and was validated using the validation set...

PURPOSE: Although large-scale randomised clinical trials have established that radiotherapy (RT) - alone or combined with hormonal therapy (HT) - is effective in reducing the risk of ipsilateral breast tumour recurrence (IBTR), overall survival does not seem to be improved by adjuvant therapies. We sought to ascertain whether specific criteria can be adopted to avoid RT with an acceptable rate of IBTR after breast-conserving surgery (BCS) achieving tumour-free margins. PATIENTS AND METHODS: This non-randomised prospective study concerned the outcome of patients who underwent BCS for ductal carcinoma in situ (DCIS) and were prospectively assessed by means of an established scoring system based on width of free margins in association with age <40, presence of comedonecrosis, high grade, ER negativity and HER2 positivity, to orient the use of any adjuvant therapies...

BACKGROUND: Nodal recurrence following negative sentinel lymph node biopsy (SLNB) for melanoma is known as false-negative (FN) SLNB. Risk factors for FN SLNB among patients with trunk and extremity melanoma have not been well-defined. METHODS: After retrospective review, SLNB procedures were classified FN, true positive (TP; positive SLNB), or true negative (TN; negative SLNB without recurrence). Factors associated with high false negative rate (FNR) and low negative predictive value (NPV) were identified by comparing FNs to TPs and TNs, respectively...

OBJECTIVE: To determine rates of axillary dissection (ALND) and nodal recurrence in patients eligible for ACOSOG Z0011. BACKGROUND: Z0011 demonstrated that patients with cT1-2N0 breast cancers and 1 to 2 involved sentinel lymph nodes (SLNs) having breast-conserving therapy had no difference in locoregional recurrence or survival after SLN biopsy alone or ALND. The generalizability of the results and importance of nodal radiotherapy (RT) is unclear. METHODS: Patients eligible for Z0011 had SLN biopsy alone...

Non-muscle-invasive bladder cancer (NMIBC) is a highly recurrent tumor despite intravesical immunotherapy instillation with the bacillus Calmette-Guérin (BCG) vaccine. In a prospective longitudinal study, we took advantage of BCG instillations, which increase local immune infiltration, to characterize immune cell populations in the urine of patients with NMIBC as a surrogate for the bladder tumor microenvironment. We observed an infiltration of neutrophils, T cells, monocytic myeloid-derived suppressor cells (M-MDSCs), and group 2 innate lymphoid cells (ILC2)...

In mucoepidermoid carcinoma (MEC), the most common salivary gland carcinoma, there is a lack of novel prognostic markers, but post-operative early recurrence strongly affects the clinical course and a poor outcome. It is critical to predict which MEC patients are prone to develop recurrence/metastases. Mucins play pivotal roles in influencing cancer biology, thus affecting cell differentiation, adhesion, carcinoma invasion, aggressiveness and/or metastatic potential. Our aim is to elucidate the significance of expression profiles for mucins, particularly MUC4 and MUC6, and their correlations with various clinicopathological features and recurrence in salivary gland MECs...

The case presented is a 25-year-old male with a malignant neuroectodermal tumour on the left chest wall (Askin tumour), treated with surgery after neoadyuvant chemotherapy and followed by consolidation chemotherapy. After 9 years of disease free survival, the patient developed an acute pulmonary embolism. The echocardiogram, thoracic CT, and cardiac MRI scans revealed a mass in the right atrium. Recurrence of an Askin tumour versus an atrium myxoma was suspected. (18)F-FDG PET/CT showed an intense hypermetabolic right atrium mass with extension to the right ventricle highly suggestive of malignancy...

PURPOSE: Sentinel node biopsy (SNB) after neoadjuvant therapy (NAT) for breast cancer remains controversial. We conducted a retrospective study of patients who underwent SNB after NAT to evaluate the effectiveness of this procedure. METHODS: A consecutive 105 women with locally advanced breast cancer (cT1-4, cN0-3, M0) were treated with NAT between 2006 and 2015. The subjects were 80 of these patients who became or remained clinically node-negative after NAT, 53 of whom had axillary management determined by SNB (group A) and the other 27 underwent axillary lymph node dissection (ALND) without SNB (group B)...

The incidence of squamous cell carcinoma of the oropharynx (SCCOP) continues to rise because of increasing rates of human papillomavirus (HPV) infection. Inherited polymorphisms in DNA repair pathways may influence the risk of SCCOP development and the prognosis of SCCOP. We sought to determine whether polymorphisms in microRNA (miRNA)-binding sites within 3'-untranslated regions (3'UTRs) of genes in DNA repair pathways modulate the risk of SCCOP recurrence. We evaluated the associations between nine such polymorphisms and SCCOP recurrence in 1008 patients with incident SCCOP using the log-rank test and multivariable Cox models...

INTRODUCTION: Many early stage non-small-cell lung cancer (NSCLC) patients who are not considered candidates for adjuvant treatment according to current guidelines do harbor occult metastasis, and have disease recurrence despite complete resection. Although National Comprehensive Cancer Network (NCCN) guidelines suggest clinicopathologic characteristics to identify high-risk patients for adjuvant intervention, molecular profiling more accurately predicts 5-year survival. Early evidence of clinical benefit from application of this molecular-based management strategy, however, has not been reported...
