PURPOSE Approximately 30% of patients with stage IB non-small-cell lung cancer (NSCLC) die within 5 years after surgery. Current staging methods are inadequate for predicting the prognosis of this particular subgroup. This study identifies prognostic markers for NSCLC. PATIENTS AND METHODS We used computer-generated random numbers to study 148(More)
Primary small cell carcinoma (SCC) of the breast, an exceedingly rare and aggressive tumor, is often characterized by rapid progression and poor prognosis. We report a case of primary SCC of the breast that was diagnosed through pathologic and immunohistochemical examinations. Computed tomography (CT) scans failed to reveal a non-mammary primary site. Due(More)
Signet-ring cell carcinoma (SRCC) can arise from virtually all organs. However, primary SRCC of the breast is very rare. Until 2003, SRCC was placed under 'mucin-producing carcinomas' and separated from other carcinomas by the World Health Organization (WHO). To date, only a few cases have been reported. A case of a 46-year-old woman with primary SRCC of(More)
OBJECTIVE To discuss the strategy of mediastinoscopy for the evaluation of mediastinal lymph node status (metastasis or not) of non-small cell lung cancer (NSCLC) prior to surgery. METHODS From October 2000 to June 2007, 152 consecutive NSCLC cases pathologically proven and clinically staged I-III were enrolled in the study. Of the 152 cases, there were(More)
Wire localization (WL) is traditionally performed before excisional biopsy for patients with nonpalpable breast lesions, but it has several disadvantages. Our current study examines whether the method of radiocolloid combined with methylene dye localization (RCML) has an advantage over WL. From August 2006 to May 2009, 157 patients with nonpalpable breast(More)
BACKGROUND & OBJECTIVE Whether to apply routine mediastinoscopy to non-small cell lung cancer (NSCLC) of stage I remains controversial. This study was to evaluate application of cervical mediastinoscopy in detecting mediastinal lymph nodes status of NSCLC of stage I. METHODS The cervical mediastinoscopy was performed in 31 patients with NSCLC of stage I(More)
BACKGROUND & OBJECTIVE Axillary lymph node dissection (ALND) is routinely performed during surgery for breast cancer, but whether ALND could increase survival rate of early stage breast cancer patients remains controversial. Recently, replacing ALND with sentinel lymph node (SLN) biopsy has became a hotspot in breast cancer research. This study aimed to(More)
