Prognostic nomograms for nasopharyngeal carcinoma with nodal features and potential indication for N staging system: Validation and comparison of seven N stage schemes.

Purpose: To identify the prognostic value of the nodal features, propose a nomogram-based N stage system and evaluate the performance of seven N stage schemes of nasopharyngeal carcinoma (NPC) patients.

Methods: Data from 1638 non-distant metastatic NPC patients were used to develop nomograms predicting 3-year and 5-year overall survival (OS) and distant metastasis-free survival (DMFS). Based on nomogram and multivariate analyses, a new N-stage scheme was proposed.

Differentiation of renal cell carcinoma subtypes through MRI-based radiomics analysis.

Objectives: To explore whether clear cell renal cell carcinoma (ccRCC), papillary renal cell carcinoma (pRCC), and chromophobe renal cell carcinoma (cRCC) can be distinguished using radiomics features extracted from magnetic resonance (MR) images.

Methods: Seventy-seven patients (ccRCC = 32, pRCC = 23, cRCC = 22) underwent MRI before surgery between May 2013 and August 2018 in this retrospective study. Thirty-nine radiomics features were extracted from tumor volumes on three sequences (T2WI, EN-T1WI CMP, and EN-T1WI NP).

Performance of breast cancer screening methods and modality among Chinese women: a report from a society-based breast screening program (SBSP) in Shanghai.

To evaluate the screening performance of individual and combined use of clinical breast examination, ultrasonography and mammography in Chinese women, we conducted a biennial breast cancer screening program among 14,464 women aged 35 to 74 years old who lived in Qibao County, Minhang district of Shanghai, China, between May 2008 and Sept 2012. All participants were submitted to clinical breast examination, and then women with positive results and all women at age of 45-69 years old were preformed breast ultrasonography and mammography. The examination results were compared against pathological findings as the gold standard of reference.

Application of breast ultrasound in a mammography-based Chinese breast screening study.

We evaluated the clinical significance of the combined use of mammography + ultrasound as a new breast screening strategy. The inclusion criteria were: (1) females aged >40yrs; (2) breast cancer diagnosis by the breast image screening personnel at FUSCC; (3) screening by both ultrasound and mammography; (4) mammographic/sonographic images analyzed independently by different radiologists; and (5) follow-up for at least 1 year. Fifty-four women were enrolled.

[Diagnostic value of full-field digital mammography for breast carcinoma].

Objective: To evaluate the diagnostic value of full-field digital mammography for breast cancer.

Methods: The clinical data and mammograms of 230 patients with breast diseases between January 2008 and July 2008 were collected and reviewed. Craniocaudal (CC) and mediolateral oblique (MLO) view mammograms were performed in all patients before surgery.

Patterns of level II node metastasis in nasopharyngeal carcinoma.

Purpose: To explore the pattern of metastasis to level II nodes and its relationship with tumor range in nasopharyngeal carcinoma (NPC) patients by using magnetic resonance imaging.

Methods And Materials: Magnetic resonance images of 618 NPC patients were reviewed. Nodes were classified as metastatic based on size criteria, the presence of nodal necrosis, and extracapsular spread.

[Evaluation of MRI in nasopharyngeal carcinoma with cavernous sinus infiltration].

Objective: To investigate the incidence, MRI characteristics and invasion route of nasopharyngeal carcinoma (NPC) infiltrating the cavernous sinus.

Methods: The data of 141 patients with histologically proven NPC collected from May 2003 to June 2004 were reviewed. All patients were examined by 1.
