abstract   background: the iranian breast cancer patients are relatively younger than their western counterparts. evidence suggests that alterations in estrogen signaling pathways , including estrogen receptor-α (er- α ), occur during breast cancer development in caucasians. epidemiologic studies have revealed that age-incidence patterns of breast cancer in asians differ from those in caucasian...

OBJECTIVES To explore the rule of subcarinal lymph node metastasis in thoracic oesophageal cancer and its clinical significance in the radical resection of oesophageal cancer. METHODS We retrospectively analysed 2223 patients with oesophageal cancer who were admitted to Henan Cancer Hospital during 2004-2011 and underwent surgery as the first treatment option. Routine subcarinal lymph node di...

background : sentinel lymph node biopsy is used as an accurate staging procedure to detect early breast cancer. several studies have documented that sentinel lymph node biopsy can accurately determine the status of axillary nodes. sentinel node biopsy offers the advantage of accurately staging the axilla and eliminating the need for a full axillary dissection for patients who have a negative se...

background: sentinel lymph node biopsy (slnb) has replaced axillary lymph node dissection (alnd) in early breast cancer patients as the first line surgical approach to axillary nodes. further dissection is performed only when sln is involved by tumor cells. however, in a significant proportion of patients, non-sentinel nodes are still not involved and axillary dissection has no additional thera...

BACKGROUND Central and lateral lymph node metastases are quite common in patients with papillary thyroid carcinoma, and the predictors for those metastases have been well studied. Right upper paraesophageal lymph node metastasis has rarely been studied. The aim of this study was to identify the clinicopathological characteristics that may be risk factors for right upper paraesophageal lymph nod...

Introduction: 18F-FDG PET/CT provides very effective results in detecting metastases of breast cancer. In our study, we investigated the relationship between maximum standard uptake value (SUVmax) and prognostic pathologic factors in breast cancer cases with isolated bone metastasis and whether there was any difference in terms of prognostic pathologic factors betwee...

Introduction: one of the foremost usual methods for evaluating breast cancer is the removal of axillary lymph nodes (ALN) which include complications such as edema, limited hand movements, and lymph accumulation. Although studies have shown that the sentinel gland condition represents the axillary nodules context in the mammary gland, the efficacy, and safety of the guard node biopsy need to be...

Objective: The purpose of the present study was to investigate the incidence and risk factors of para-aortic lymph node metastasis in stages IB, IIA and IIB cervical carcinoma and provide the basis for para-aortic lymph node dissection. Method: Four hundred and twenty-three patients with stages IB, IIA and IIB cervical cancer who had undergone radical hysterectomy, pelvic lymphadenectomy, and p...

PURPOSE To investigate the effects of lymph node metastasis, skip metastasis, and other factors related to lymph node status on survival in patients who underwent radical cystectomy (RC) and extended lymph node dissection (eLND). MATERIALS AND METHODS RC and eLND were performed in 85 patients with a diagnosis of bladder cancer. Disease-free survival (DFS) and overall survival (OS) were determ...
