INTRODUCTION The purpose of this study was to identify tumor characteristics of primary malignant melanoma predictive of sentinel lymph node positive status, and then to determine whether sentinel lymph node status has an impact on recurrence and survival. MATERIAL AND METHODS A total of 100 patients with primary malignant skin melanoma were analyzed. The prospective melanoma database identif...
The aim of this study was to evaluate the possibility of identifying the sentinel lymph node and involvement of neoplastic cells in patients with endometrial carcinoma limited to the uterus, and also its correlation with the conditions of other pelvic and para-aortic lymph nodes. Forty patients with endometrial carcinoma, clinical staging I and II, were submitted to complete surgical staging th...
BACKGROUND Sentinel lymph node biopsy has been established as the preferred method for staging early breast cancer. A prior history of mastectomy is felt to be a contraindication. CASE PRESENTATION A patient with recurrent breast cancer in her skin flap was discovered to have positive axillary sentinel nodes by sentinel lymph node biopsy five years after mastectomy for ductal carcinoma in sit...
CONTEXT Cutaneous melanoma presents significant morbidity and mortality. Nowadays, about 90% of them are diagnosed by clinical examination and most are localized melanomas. Sentinel node biopsy has brought about a new and interesting approach towards localized cutaneous melanoma. The meaning of micrometastases in sentinel nodes diagnosed by the reverse transcriptase-polymerase chain reaction is...
Oncologic staging of many solid organ malignancies involves an understanding of how cancers spread via the lymphatic system, and ultimately may involve evaluation of the primary nodal drainage basin by performing a sentinel lymph node biopsy. In the adult population, there are well established indications for sentinel lymph node biopsy in diseases like melanoma and breast cancer. However, its u...
BACKGROUND Regional lymph node surgical management is an integral part of cervical cancer therapy. In gynaecological oncology, recent studies have confirmed the utility of the sentinel node concept in vulvar and cervical cancer. The method of the marker's administration is considered to play an important role in sentinel node detection. MATERIAL AND METHODS 60 patients with cervical cancer (s...
Background. Most institutions require a patient undergoing sentinel lymph node biopsy to go through nuclear medicine prior to surgery to be injected with radioisotope. This study describes the long-term results using intraoperative injection of radioisotope. Methods. Since late 2002, all patients undergoing a sentinel lymph node biopsy at the Yale-New Haven Breast Center underwent intraoperativ...
Vulvar cancer is a rare gynecological malignancy with mainly lymphatic spread. Sentinel node mapping plays an important role in the management of this gynecological malignancy. In the current study, we reported our experience in sentinel node mapping of vulvar cancer and review the literature accordingly. Since the introduction of sentinel node mapping to the surgical oncology community of our ...
BACKGROUND Sentinel lymph node biopsy in women with operable breast cancer is routinely used in some countries for staging the axilla despite limited data from randomized trials on morbidity and mortality outcomes. We conducted a multicenter randomized trial to compare quality-of-life outcomes between patients with clinically node-negative invasive breast cancer who received sentinel lymph node...
