Abstract Background The three-material decomposition method (3MD) of dual-energy applications can quantify iodine and fat contents the tumor. purpose this study was to assess usefulness quantifying in tumor grade, lymphovascular invasion, pleural invasion predict aggressiveness lung cancer (LC) using computed tomography (DECT). We prospectively analyzed cases 32 patients with tumors who underwe...

The relationship between dilated blood vessels in the tumor periphery and the tumor invasion depth is unclear. Therefore, the present study aimed to clarify the relationship between dilated blood vessels and the invasion depth of small-sized (<30 mm) colorectal cancer (CRC), and its implications on endoscopic treatment.We performed a single-arm observational study of the diagnostic accuracy of ...

OBJECTIVE To assess the prognostic value of proliferating cell nuclear antigen (PCNA) in laryngeal carcinoma and its relation with other known prognostic clinicopathologic variables. DESIGN A retrospective cohort study of 92 patients chosen randomly from patients treated between 1964 and 1993 with the diagnosis of laryngeal cancer. Prognostic factors including PCNA expression, grade, lymphova...

BACKGROUND Identification of poor prognostic factors in papillary thyroid carcinoma (PTC) patients is important for the patients' care and follow-up. We can sometimes see small tumor clusters without desmoplasia and no evidence of lymphatic emboli around the main tumor mass of PTC. We termed this form of tumor clustering, 'tumor sprouting,' and determined whether these tumors correlate with lym...

BACKGROUND The value of frozen sections in the intraoperative examination of sentinel nodes (SN) remains controversial. Accurate frozen sections will spare those patients with node metastasis from a second procedure to complete the axillary dissection. We examined our own experience with intraoperative examination of SN. STUDY DESIGN Between January 1, 2006, and December 31, 2006, we performe...

A search for factors predicting the behavior of tumor, its invasiveness, metastasis, response to treatment, and prognosis is primary focus breast cancer research. The objective present study was association fibrinogen vascular endothelial growth factor (VEGF) with various parameters carcinoma. case control conducted in which fibrinogen, VEGF levels were compared between cases controls also char...

OBJECTIVES/HYPOTHESIS To identify histopathologic features associated with poor correlation of frozen and permanent pathology margins following wide local excision for advanced cutaneous squamous cell carcinomas of the head and neck. STUDY DESIGN Retrospective review. METHODS A retrospective review of patients undergoing excision of advanced head and neck squamous cell carcinomas between th...

PURPOSE This study aimed to identify the surgical-pathologic risk factors of lymph node metastasis (LNM) in patients with early stage squamous cell cervical cancer and to evaluate the potential efficacy of omitting pelvic lymphadenectomy. METHODS A total of 276 patients with stage IA2, IB1, and IIA1 squamous cell cervical cancer receiving primary radical hysterectomy with pelvic lymphadenecto...
