The tumor suppressor gene adenomatous polyposis coli (APC) is mutated in most colorectal cancers (CRCs), resulting in constitutive Wnt activation. To understand the Wnt-activating mechanism of the APC mutation, we applied CRISPR/Cas9 technology to engineer various APC-truncated isogenic lines. We find that the β-catenin inhibitory domain (CID) in APC represents the threshold for pathological levels of Wnt activation and tumor transformation. Mechanistically, CID-deleted APC truncation promotes β-catenin deubiquitination through reverse binding of β-TrCP and USP7 to the destruction complex...

BackgroundRadiotherapy is an effective treatment for intermediate/high-risk locally-advanced prostate cancer, however, >30% of patients relapse within five years. Clinicopathological parameters currently fail to identify patients prone to systemic relapse and those whom treatment intensification may be beneficial. The purpose of this study was to independently validate the performance of a 70-gene Metastatic Assay in a cohort of diagnostic biopsies from patients treated with radical radiotherapy and androgen deprivation therapy (ADT)...

Background: The presence of stromal tumor-infiltrating lymphocytes (TILs) is associated with increased pathological complete response (pCR) and improved outcomes in HER2-positive early breast cancer (BC) treated with anti-HER2-based chemotherapy. In the absence of chemotherapy, the association of TILs with pCR following anti-HER2 therapy-only is largely unknown. Patients and methods: The PAMELA neoadjuvant trial treated 151 women with HER2-positive BC with lapatinib and trastuzumab (and hormonal therapy if hormone receptor [HR]-positive) for 18 weeks...

BACKGROUND: Novel immune checkpoint blockade strategies are being evaluated in clinical trials and include targeting the lymphocyte activation gene 3 (LAG-3) checkpoint, alone or in combination with PD-1/PD-L1 blockade. We investigated LAG-3 expression and its prognostic value in a large series of breast cancer patients, and correlated LAG-3 expression with key biomarkers including PD-1 and PD-L1. EXPERIMENTAL DESIGN: LAG-3 expression was evaluated by immunohistochemistry (IHC) on two tissue microarray series incorporating 4322 breast cancer primary excision specimens (N=330 in the training and N= 3,992 in the validation set) linked to detailed clinico-pathological, biomarker and long term clinical outcome data...

Background: On the basis of historical data, patients with cancers of unknown primary (CUP) are generally assumed to have a dismal prognosis with overall survival of less than one year. Treatment is typically cytotoxic chemotherapy guided by histologic features and the pattern of metastatic spread. The purpose of this study was to provide a clinical and pathologic description of patients with CUP in the modern era, to define the frequency of clinically actionable molecular alterations in this population, to determine how molecular testing can alter therapeutic decisions, and to investigate novel uses of next generation sequencing in the evaluation and treatment of patients with CUP...

Detailed pathologic studies over the past decade suggest a distal fallopian tube origin for the majority of "ovarian" high-grade serous carcinomas (HGSC). This review will summarize molecular alterations observed in tubal precursors for HGSC, namely p53 signatures and serous tubal intraepithelial carcinomas, and in nonmalignant fallopian tube epithelial cells obtained from women at increased genetic risk for HGSC. Recent experiments investigating the impact of follicular fluid exposure and retrograde menstruation on tumor development in the fallopian tube will also be discussed...

OBJECTIVES: Following radical prostatectomy (RP), adjuvant radiation therapy (RT) decreases biochemical recurrence and potentially improves metastasis-free and overall survival for patients with high-risk pathologic features. Since adjuvant RT typically occurs daily over several weeks, the logistical challenges of extensive traveling may be a significant barrier to its use. We examined the association between distance to treatment facility and use of adjuvant RT. MATERIALS AND METHODS: We identified 97,568 patients in the National Cancer Database diagnosed from 2004 through 2011 with cT1-4N0-xM0-x prostate cancer and found to have high-risk pathologic features (pT3-4 stage and/or positive surgical margins) at RP...

BACKGROUND: Anastomotic stricture following esophagogastrectomy (EG) can lead to significant dysphagia, necessitating interventions such as endoscopic dilatation. These post-operative complications gain importance with the increased survival rate of patients after EG. This study aimed to assess the outcomes of both circular-stapled (CS: 25 and 29 mm) and hand-sewn (HS) anastomoses after EG. METHODS: We reviewed prospectively accrued data from December 2004 to December 2014 identifying all patients undergoing EG for esophageal cancer...

Early metastatic dissemination and evolution of disseminated cancer cells (DCCs) outside the primary tumor is one reason for the failure of adjuvant therapies because it generates molecular geno- and phenotypes different from primary tumors which still underlie therapy decisions. Since ERBB2 amplification in esophageal DCCs but not in primary tumor cells predict outcome, we aimed to establish an assay with diagnostic reliability for single DCCs or circulating tumor cells (CTCs). For this we evaluated copy number alterations of more than 600 single DCCs from multiple cancer types to define reference regions suitable for quantification of target regions, such as ERBB2...

BACKGROUND: Mucosal melanomas in the head and neck region are most often located in the nasal cavity and paranasal sinuses. To the authors' knowledge, the prognostic effects of lymph node metastasis in patients with sinonasal mucosal melanoma (SNMM) have not been established. Therefore, the objective of the current study was to determine the effects of lymph node metastasis on survival. METHODS: The current study included 198 patients with SNMM who had been treated between 1985 and 2016 at The University of Texas MD Anderson Cancer Center in Houston...

BACKGROUND: The subspecialization of colorectal surgeons, and improvements in the quality of mesorectal excision have revolutionized rectal cancer surgery. With the increasing use of minimally invasive techniques, the completeness of the mesorectal excision has been questioned. This study aimed to assess the pathological outcomes of open versus laparoscopic rectal resection. METHODS: A meta-analysis of RCTs was undertaken. The primary endpoint was the adequacy of the mesorectal excision...

More data are needed regarding the radiology, co-morbidities and natural history of smoking-related interstitial fibrosis (SRIF), a common pathological finding, mainly described heretofore in association with lung cancer, where respiratory bronchiolitis (RB) usually co-exists. We prospectively acquired high resolution CT scan data (edge-enhancing lung reconstructions) to detect any radiologic interstitial lung abnormality (ILA) in individuals who ultimately underwent surgical lobectomy for lung cancer (n = 20), for radiologic/pathologic correlation...

Here, we present two approaches to map DNA double-strand breaks (DSBs) and single-strand breaks (SSBs) in the genome of human cells. We named these methods respectively DSB-Seq and SSB-Seq. We tested the DSB and SSB-Seq in HCT1116, human colon cancer cells, and validated the results using the topoisomerase 2 (Top2)-poisoning agent etoposide (ETO). These methods are powerful tools for the direct detection of the physiological and pathological "breakome" of the DNA in human cells.

This study was conducted to investigate the expressions of DDR2 and IFITM1 and their clinical and pathological significances in the rare type squamous cell/adenosquamous carcinomas (SC/ASC) and ordinary adenocarcinomas (AC) of gallbladder cancers. DDR2 and IFITM1 expression was examined in 69 SC/ASCs and 146 ACs using EnVision immunohistochemistry. Results showed that the percentage of positive DDR2 and IFITM1 expression was significantly higher in SC/ASC patients with high TNM stage, lymph node metastasis, invasion, and no resection surgery compared to patients with low TNM stages, no lymph node metastasis, no invasion, and resection surgery (P < 0...

BACKGROUND: The current (seventh edition) American Joint Commission on Cancer (AJCC) Staging System for pancreatic ductal adenocarcinoma (PDAC) dichotomizes pathologic lymph node (LN) involvement into absence (pN0) or presence (pN1) of disease. The recently announced eighth edition also includes stratification on the number of positive nodes. Furthermore, LNs detected on preoperative imaging (CT, MRI, or endoscopic ultrasound-EUS) are considered to be pathologically involved in other gastrointestinal cancers...
