Objective To address terminology and other issues related to thyroid fine-needle aspiration (FNA), the National Cancer Institute (NCI) hosted The NCI Thyroid FNA State of the Science Conference. The conclusions regarding terminology and morphologic criteria from the NCI meeting led to the Bethesda Thyroid Atlas Project and form the framework for the Bethesda System for Reporting Thyroid Cytopathology. Design Participants of the Atlas Project were selected from among the committee members of the NCI FNA State of the Science Conference and other participants at the live conference. The terminology framework was based on a literature search of English language publications dating back to 1995 using PubMed as the search engine; online forum discussions ( http://thyroidfna.cancer.gov/forums/default.aspx ); and formal interdisciplinary discussions held on October 22 and 23, 2007, in Bethesda, MD. Main outcome For clarity of communication, the Bethesda System for Reporting Thyroid Cytopathology recommends that each report begin with one of the six general diagnostic categories. Each of the categories has an implied cancer risk that links it to an appropriate clinical management guideline. Conclusions The project participants hope that the adoption of this framework will facilitate communication among cytopathologists, endocrinologists, surgeons, and radiologists; facilitate cytologic-histologic correlation for thyroid diseases; facilitate research into the understanding of thyroid diseases; and allow easy and reliable sharing of data from different laboratories for national and international collaborative studies.

The Bethesda System for Reporting Thyroid Cytopathology.

Summary Background Compared with open resection, laparoscopic resection of rectal cancers is associated with improved short-term outcomes, but high-level evidence showing similar long-term outcomes is scarce. We aimed to compare survival outcomes of laparoscopic surgery with open surgery for patients with mid-rectal or low-rectal cancer. Methods The Comparison of Open versus laparoscopic surgery for mid or low REctal cancer After Neoadjuvant chemoradiotherapy (COREAN) trial was an open-label, non-inferiority, randomised controlled trial done between April 4, 2006, and Aug 26, 2009, at three centres in Korea. Patients (aged 18–80 years) with cT3N0–2M0 mid-rectal or low-rectal cancer who had received preoperative chemoradiotherapy were randomly assigned (1:1) to receive either open or laparoscopic surgery. Randomisation was stratified by sex and preoperative chemotherapy regimen. Investigators were masked to the randomisation sequence; patients and clinicians were not masked to the treatment assignments. The primary endpoint was 3 year disease-free survival, with a non-inferiority margin of 15%. Analysis was by intention to treat. This trial is registered with ClinicalTrials.gov, number NCT00470951. Findings We randomly assigned 340 patients to receive either open surgery (n=170) or laparoscopic surgery (n=170). 3 year disease-free survival was 72·5% (95% CI 65·0–78·6) for the open surgery group and 79·2% (72·3–84·6) for the laparoscopic surgery group, with a difference that was lower than the prespecified non-inferiority margin (–6·7%, 95% CI −15·8 to 2·4; p Interpretation Our results show that laparoscopic resection for locally advanced rectal cancer after preoperative chemoradiotherapy provides similar outcomes for disease-free survival as open resection, thus justifying its use.

The Foundations Of Differential Geometry

We study Ricci-commuting real hypersurfaces in the complex hyperbolic quadric $${{Q^m}^*} = SO^{o}_{2,m}/SO_mSO_2$$
 , $$m \ge 3$$
 . The commuting Ricci tensor shows that the unit normal vector field N of $${Q^m}^*$$
 is singular, that is, $$AN=N$$
 or $$N=\frac{1}{\sqrt{2}}(Z_1+JZ_2)$$
 , $$Z_1,Z_2 \in V(A)$$
 for a complex conjugation $$A \in {\mathfrak {A}}$$
 , where $$\mathfrak {A}$$
 denotes the set of all complex conjugations in $${Q^m}^*$$
 . Then according to each case, we give a classification of real hypersurfaces having a commuting Ricci tensor in $${Q^m}^*$$
 .

Real Hypersurfaces in the Complex Hyperbolic Quadric with Commuting Ricci Tensor

On a real hypersurface M of a complex quadric we have an almost contact metric structure induced by the Kahlerian structure of the ambient space. Therefore, on M we have the Levi-Civita connection $$\nabla $$
 and, for any non-null real number k, the so called kth generalized Tanaka Webster connection $${\hat{\nabla }}^{(k)}$$
 . We introduce the notions of $$({\hat{\nabla }}^{(k)},\nabla )$$
 -Codazzi and $$({\hat{\nabla }}^{(k)},\nabla )$$
 -Killing normal Jacobi operator on such a real hypersurface and classify Hopf real hypersurface in a complex quadric whose normal Jacobi operators satisfy any of both conditions.

New Conditions on Normal Jacobi Operator of Real Hypersurfaces in the Complex Quadric

The purpose of this paper is to investigate a Chern type problem for space-like Kaehler submanifolds M in indenite complex hyperbolic space CH n+p p (c), c < 0. Accordingly, we give better estimations of the squared norm of the second fundamental form of M in CH n+p p (c), c < 0.

On a chern-type problem for space-like

In this paper, first we introduce a new notion of (quadratic) Killing normal Jacobi operator (or cyclic parallel normal Jacobi operator) and its geometric meaning for real hypersurfaces in the real Grassmannians of rank two 
 $${\mathbb {Q}}^{m}(\varepsilon )$$
 , $$\varepsilon =\pm 1$$
 , where $${\mathbb {Q}}^{m}(\varepsilon )$$
 denotes the complex quadric 
 $$\mathbb Q^{m}(\varepsilon )=Q^{m}=SO_{m+2}/SO_{m}SO_{2}$$
 for $$\varepsilon =1$$
 and $${\mathbb {Q}}^{m}(\varepsilon )= Q^{m*}=SO_{m,2}^{0}/SO_{m}SO_{2}$$
 for $$\varepsilon =-1$$
 , respectively. Next, we give a non-existence theorem for Hopf real hypersurfaces satisfying quadratic Killing normal Jacobi operator in the real Grassmannians of rank two 
 $${\mathbb {Q}}^{m}(\varepsilon )$$
 .
