Abstract LB061: On-target peripheral and tumor immune microenvironment modulation in patients treated with lacnotuzumab (anti-CSF1, MCS110) + spartal…
2021
Abstract Background: The CSF-1/CSF-1R (colony-stimulating factor-1) pathway plays a significant role in the tumor microenvironment via regulation of tumor-associated macrophages (TAMs). Lacnotuzumab (MCS110) is a humanized monoclonal antibody against CSF-1. Lacnotuzumab may counteract the tumor suppressive microenvironment induced by CSF-1, potentially enhancing the efficacy of PD-1 inhibition. Methods: MCS110Z2102 is a phase 1b/2 study in cancer patients with advanced malignancies treated by lacnotuzumab combined with the PD-1 inhibitor spartalizumab. Eligible patients with previously treated advanced/metastatic solid tumors received 1, 3, 5, 7.5 and 10 mg/kg intravenous doses of lacnotuzu…
Functional analysis ofp53 gene and the prognostic impact of dominant-negativep53 mutation in endometrial cancer
2005
In addition to the loss of function, mutant p53 can possess a dominant-negative effect on wild-type p53 and may also exert gain-of-function activity. It is not clear whether the functional status of p53 mutation contributes to differences in outcome in endometrial cancer. We collected a total of 92 RNA samples of high quality from endometrial cancer tissues, and the samples were subjected to yeast functional assay and sequencing for p53 mutations. The detected mutant p53 genes were further investigated for their dominant-negative activity using a yeast-based transdominance assay. p53 mutation was found in 24 out of 92 (26.1%) tumors, of which 10 exhibited no dominant-negative activity (rece…
Does tamoxifen change oestrogen and progesterone receptor expression in the endometrium and breast?
2000
We studied the expression of oestrogen and progesterone receptors (ER, PR) in postmenopausal women receiving tamoxifen for breast cancer. In addition the literature addressing the question of ER and PR expression in breast tissue during treatment with tamoxifen was reviewed. We demonstrated consistent expression of ER and PR in endometria from patients receiving tamoxifen, with a trend towards a higher proportion of receptor positive specimens during tamoxifen. In breast cancer tissue, the ER content seemed to be reduced following tamoxifen treatment. After short time exposure to tamoxifen, the PR appeared to be increased, longer treatment caused the PR to go down to pretreatment levels or …
Cerebral metastases of an endometrial stromal sarcoma: report of the first case.
2012
Endometrial stromal sarcomas (ESSs) of the uterus are rare gynecological malignancies. Common locations of distant metastases are vagina, vulva, lung, mediastinum, abdomen, bones and ovaries.We present the case of a 69-year-old woman with a Federation of Gynecology and Obstetrics (FIGO) IIb (classification 2009) ESS of the uterus of high-grade malignancy. Initially, a hysterectomy Piver II and total colpectomy were performed, followed by pelvic field irradiation. 8 months later, the patient suffered seizures and hemiparesis. A computed tomography (CT) scan revealed cerebral metastases, and irradiation of the brain was initiated. After completion of the staging examinations, additional metas…
Progestin-releasing intrauterine device insertion plus palliative radiotherapy in frail, elderly uterine cancer patients unfit for radical treatment.
2016
The present study investigated the combination of levonorgestrel-releasing intrauterine device (LNG-IUD) insertion and palliative radiotherapy (RT) as a potential approach for treating frail, elderly endometrial cancer (EC) patients considered unfit for curative oncological treatments. The inclusion criteria were an age of ≥65 years, pathological confirmation of a uterine neoplasm, a Charlson comorbidity index (CCI) value of ≥4 and the presence of vaginal bleeding. Patients underwent intrauterine insertion of an LNG-IUD, and thereafter, received a total dose of 30 Gy at 3 Gy per fraction, over 10 days. The clinical target volume (CTV) was defined as the uterus and disease-involved tissues i…
A Multicentric Randomized Trial to Evaluate the ROle of Uterine MANipulator on Laparoscopic/Robotic HYsterectomy for the Treatment of Early-Stage End…
2021
ObjectiveThis prospective randomized trial aimed to assess the impact of the uterine manipulator in terms of lymph vascular space invasion (LVSI) in patients undergoing minimally invasive staging for early-stage endometrial cancer.MethodsIn this multicentric randomized trial, enrolled patients were randomly allocated in two groups according to the no use (arm A) or the use (arm B) of the uterine manipulator. Inclusion criteria were G1-G2 early-stage endometrial cancer at preoperative evaluation. The variables collected included baseline demographic characteristics, perioperative data, final pathology report, adjuvant treatment, and follow-up.ResultsIn the study, 154 patients (76 in arm A an…
Validating an apple dry matter production model with whole canopy gas exchange measurements in the field
1999
The simplified apple dry matter production model developed by Lakso and Johnson (1990) was modified by inputing tree-specific parameters from a study of seasonal growth and gas exchange of 4-year-old Empire/M.9 apple trees, and light and temperature response curves developed for Empire apple organs. Measurements of the seasonal trend of diurnal net C02 and canopy water vapor exchange were made at intervals on three four-year-old 'Empire'/M.9 slender spindle apple trees in the orchard from 10 days after bloom until 25 days after harvest. The tree canopies were enclosed in clear plastic "balloon- type" chambers (similar to Corelli and Magnanini, 1993) that was monitored continuously for more …
Effects of partial rootzone drying and rootstock vigour on dry matter partitioning of apple trees (Malus domesticacvar Pink Lady)
2011
SUMMARYThe effects of partial rootzone drying (PRD) and rootstock vigour on dry matter accumulation and partitioning among leaves, shoots, fruits, frame and roots of apple trees (Malus domesticaBorkh. cvar Pink Lady) were investigated in 2005 near Caltavuturo, in Sicily. In a first field trial, trees on MM.106 rootstock were subjected to: conventional irrigation (CI), maintaining soil moisture above 0·80 of field capacity; PRD irrigation, where alternating sides of the rootzone received 0·50 of the CI irrigation water; and continuous deficit irrigation (DI), where 0·50 of the CI water was equally applied to both sides of the rootzone. In a second trial, trees on M.9 or MM.106 were subjected…
Cardiac output following fetoscopic coagulation of major placental vessels in fetal sheep.
2008
Objectives To measure changes in cardiac output (CO) after partial cord occlusion in fetal sheep in order to investigate pathophysiological fetal adaptation mechanisms in a simulated acute placental insufficiency model under standardized conditions, with the aim of finding relevant methods for monitoring human fetuses during stress situations. Methods We used minimally invasive, percutaneous endoscopic techniques to close umbilical vessels in mid-gestational fetal sheep. Placental blood flow was reduced by preferentially closing first arterial and then the concomitant venous umbilical vessels within a short time interval. The investigations were carried out on 11 pregnant ewes at a median g…
