Abstract Expansion of antigen-experienced CD8 + T cells is critical for the success tumour-infiltrating lymphocyte (TIL)-adoptive cell therapy (ACT) in patients with cancer 1 . Interleukin-2 (IL-2) acts as a key regulator cytotoxic functions by promoting expansion and capability 2,3 Therefore, it essential to comprehend mechanistic barriers IL-2 sensing tumour microenvironment implement strategies reinvigorate responsiveness antitumour responses. Here we report that prostaglandin E2 (PGE 2...

TPS611 Background: Axillary lymph node dissection (ALND) is standard of care for most patients with clinically node-positive breast cancer (cN+BC), either in the adjuvant setting or case residual nodal disease after neoadjuvant chemotherapy (NACT). At least one quarter experience long term morbidity ALND. The TAXIS trial was designed to investigate if axillary radiotherapy (ART) can replace ALND cN+ BC who underwent tailored surgery (TAS), which recognized as important uncertainties and...

Background. Vaginal hysterectomy (VH) is being performed increasingly by gynecologic surgeons. Thus, enlarged uteri are more frequently removed vaginally, requiring reducing techniques to allow vaginal extraction. Material and methods. We designed a randomized prospective study compare bisection–morcellation myometrial coring. Patients scheduled for VH or laparoscopically assisted (LAVH) were offered entry into the study. Endometrial cancer was an exclusion criterion. Uterine size not...

To assess the effect of laparoscopy on circulating tumor cell (CTC) detection in case carcinosis.We compared versus laparotomy blood release an animal model ovarian carcinosis obtained by intraperitoneal inoculation IGR-OV1 cells nude rats. Animals were randomly assigned to one following groups: CO(2) (L), gasless (GL), midline (ML), or general anesthesia as control (C).

In gynecological surgery to date, two distinct types of endoscopic accesses have been used perform para-aortic lymphadenectomies: transperitoneal and extraperitoneal, each with advantages disadvantages.1 We propose develop a new mini-invasive access an extraperitoneal lymphadenectomy via single-port umbilical device that, our knowledge, has never described. This innovative approach combines both intraperitoneal procedure the same incision using one single trocar. A 3–4 cm trans-umbilical is...
