We compared the efficiency and safety of 12 laparoscopic and 13 abdominal hysterectomies performed with bilateral salpingo-oophorectomy in the operative treatment of endometrial cancer. In all patients, the surgery was extended to include pelvic lymphadenectomy, where the histopathological examination confirmed advanced disease greater than IB (according to FIGO). Our work confirms that laparoscopic hysterectomy with bilateral salpingo-oophorectomy in endometrial cancer is a safe procedure for the patient and it seems to be more effective in lymph node sampling to abdominal surgery (via laparotomy). Moreover, complications are less frequent and severe when the patient is operated via the laparoscopic approach.

Introduction: Sentinel lymph node biopsy is an increasingly popular method of breast cancer treatment. In order to determine the number and location of potentially positive nodes, it is necessary to perform sentinel node lymphoscintigraphy. The quality of the image depends on the use of the appropriate method of radionuclide imaging. The aim of this study was to compare the sensitivity of SPECT, SPECT/CT and classical planar acquisitions in the detection of sentinel lymph nodes for sentinel node lymphoscintigraphy in breast cancer. In addition, we tried to verify the usefulness of the morphological image obtained by SPECT/CT to specify their location. Materials and methods: We studied women (mean age = , SD = . ) with histologically con irmed breast cancer (T -N M ). Planar, SPECT and SPECT/CT images were interpreted separately in terms of the number and location of sentinel lymph nodes and lymphatic drainage direction. Results: Planar images detected sentinel lymph nodes, while SPECT and SPECT/CT showed nodes (about % more).In ( %) patients SPECT imaging detected more sentinel lymph nodes than planar. Planar imaging was negative for the identiication of sentinel lymph nodes in ( %) patients. SPECT/CT images showed sentinel lymph nodes in all patients. The node to background ratio on the planar images was . , on the SPECT . , and on the SPECT/CT . . The direction of lymphatic drainage and location of axillary lymph nodes were established only on SPECT/CT images. Conclusions: The use of SPECT imaging for sentinel node lymphoscintigraphy in breast cancer increases the sensitivity of sentinel lymph nodes detection. The use of low-dose CT as attenuation correction for SPECT images improves their contrast without a signi icant effect on the number of detected sentinel lymph nodes. It also brings important anatomical information, which is dif icult or even impossible to determine by planar and SPECT images.

ABSTRAKT Wstęp: Biopsja węzła wartowniczego jest coraz częściej wybieraną metodą leczenia raka sutka. W celu określenia liczby i lokalizacji potencjalnie zajętych węzłów niezbędne jest przeprowadzenie limfoscyntygra ii węzła wartowniczego. Jakość powstałych obrazów limfoscyntygra icznych zależy od doboru odpowiednio czułej metody obrazowania. Celem pracy było porównanie czułości techniki tomogra ii emisyjnej pojedynczego fotonu (SPECT), techniki fuzyjnej łączą-cej SPECT z tomogra ią komputerową (SPECT/CT) i klasycznej akwizycji planarnej w detekcji węzłów wartowniczych w limfoscyntygra ii u chorych na raka sutka oraz ocena przydatności obrazu morfologicznego uzyskanego za pomocą SPECT/CT do ich lokalizacji. Materiały i metody: Przebadano kobiety (średni wiek -lat, SD = , ) z potwierdzonym histopatologicznie rakiem sutka (T -N M ). U wszystkich pacjentek wykonano limfoscyntygraię węzłów wartowniczych kolejno metodami: planarną, SPECT i SPECT/CT. Otrzymane obrazy porównano pod względem li...
