The correct staging of the tumors has important consequences in the planning of the treatment in the patients with cancer of larynx, hypopharynx and oropharynx. The objective of this paper is to study the correlation of the clinical, radiologic and pathologic staging with the purpose to evaluate if the computed tomography (CT) is effective in the diagnostic of the stage in the different tumoral findings. We did a retrospective study in 34 patients with pharynx and larynx cancer in the "Hospital Universitario Príncipe de Asturias" between the years 1994-1998. The method was: 1. Clinical history and ENT examination. 2. Head and neck CT. 3. Direct laryngoscopy and biopsy. 4. Surgical treatment and posterior pathologic staging of the removed specimen. The lesions were studied according the TNM-UICC classification with the T and N stage. The first thing to do was the clinical stage then the radiologic stage and at last compare it with the pathologic stage after surgical removal. The results are presented in percentages and confirm that the clinical and radiologic combined information improve the correlation between clinical and pathologic staging in the cancer of larynx, hypopharynx and oropharynx.

Department of Biostatistics, Soon Chun Hyang University Hospital Bucheon, Bucheon, Gyeonggi-do, Korea (the Republic of).
This study investigated the additional radiation exposure, influencing factors, and clinical significance of overlapping Z-axis coverage in abdominopelvic CT scans performed consecutively after same-day chest CT scans. Data from 761 patients were analyzed, with measuring the total and overlapping Z-axis coverage of the portal venous phase in abdominopelvic CT scans. The average overlapping portion was 33.

Background: Patients with human epidermal growth factor receptor 2 (HER2)-positive early breast cancer with residual invasive disease after neoadjuvant systemic therapy have a high risk of recurrence and death. The primary analysis of KATHERINE, a phase 3, open-label trial, showed that the risk of invasive breast cancer or death was 50% lower with adjuvant trastuzumab emtansine (T-DM1) than with trastuzumab alone.
Methods: We randomly assigned patients with HER2-positive early breast cancer with residual invasive disease in the breast or axilla after neoadjuvant systemic treatment with taxane-based chemotherapy and trastuzumab to receive T-DM1 or trastuzumab for 14 cycles.

Background: Zoledronate prevents fractures in older women when administered every 12 to 18 months, but its effects on bone density and bone turnover persist beyond 5 years. Whether infrequent zoledronate administration would prevent vertebral fractures in early postmenopausal women is unknown.
Methods: We conducted a 10-year, prospective, double-blind, randomized, placebo-controlled trial involving early postmenopausal women (50 to 60 years of age) with bone mineral density T scores lower than 0 and higher than -2.

Contrast-enhanced mammography (CEM) is growing in clinical use due to its increased sensitivity and specificity compared to full-field digital mammography (FFDM) and/or digital breast tomosynthesis (DBT), particularly in patients with dense breasts. To perform an intraindividual comparison of MGD between FFDM, DBT, a combination protocol using both FFDM and DBT (combined FFDM-DBT), and CEM, in patients undergoing breast cancer screening. This retrospective study included 389 women (median age, 57.

Background: Refractory ascites (RA) remains a serious complication in patients with cirrhosis. Currently, the insertion of a TIPS is considered the standard of care in these patients. To achieve symptom control in those with TIPS contraindications, tunneled peritoneal catheters (PeCa) or ascites pumps were introduced.
