Carcinoma of the neovagina: case report and review of the literature.

2001

Abstract Background. Carcinoma of the vagina is a rare disease, and it is even more rare in the neovagina. Nevertheless, it has been well described. The aim of this report was to analyze the reported cases and to add observations concerning a risk profile for this rare occurrence of carcinoma. Case report. The 29-year-old patient's history included congenital absence of vagina as a result of Rokitansky–Kuster syndrome. In 1987, when the patient was 17 years old, a neovagina was constructed by dissection between the bladder and the rectum, according to the Warthon method, and the apex of the neovagina was covered with Dura-mater. In 1990 the patient underwent radiation treatment with brachyt…

Laparoscopic Management of Ovarian Cancer Patients With Localized Carcinomatosis and Lymph Node Metastases: Results of a Retrospective Multi-institut…

2016

Abstract Study Objective To investigate the feasibility and safety of laparoscopic cytoreduction in ovarian cancer patients with localized carcinomatosis or lymph node involvement. Design Retrospective cohort study (Canadian Task Force classification II-2). Setting Multi-institutional study performed in 6 referral gynecologic oncology units. Patients Between June 2005 and December 2014, preoperatively presumed early-stage ovarian cancer patients, who accidentally revealed localized carcinomatosis or lymph node involvement at laparoscopic evaluation or at postoperative pathological examination managed by the laparoscopic approach. Interventions All patients with limited carcinomatosis and/or…

Minilaparoscopic aortic lymphadenectomy.

2015

Abstract Study Objective To show the feasibility of performing aortic lymphadenectomy with 3-mm instruments in gynecologic malignancies. Patient A 43-year-old, multiparous patient with serous ovarian cancer grading 2, Federation Internationale de Gynecologie et d'Obstetrique stage IC (intraoperative spillage). Intervention The patient was accidentally diagnosed with ovarian cancer after a right adnexectomy performed for an ovarian cyst. Once referred to our center, a delayed surgical staging was planned including total hysterectomy, left adnexectomy, aortic and pelvic lymphadenectomy, peritoneal biopsies, and total omentectomy. Minilaparoscopy was believed to be feasible to achieve it. Meas…

In vivo biodistribution and lifetime analysis of cy5.5-conjugated rituximab in mice bearing lymphoid tumor xenograft using time-domain near-infrared …

2008

Rituximab is a chimeric monoclonal antibody directed against human CD20 antigen, which is expressed on B-cell lymphocytes and on the majority of B-cell lymphoid malignancies. Herein we report the conjugate of rituximab with the near-infrared (NIR) fluorophore Cy5.5 (RI-Cy5.5) as a tool for in vitro, in vivo, and ex vivo NIR time-domain (TD) optical imaging. In vitro, RI-Cy5.5 retained biologic activity and led to elevated cell-associated fluorescence on tumor cells. In vivo, TD optical imaging analysis of RI-Cy5.5 injected into lymphoma-bearing mice revealed a slow tumor uptake and a specific long-lasting persistence of the probe within the tumor. Biodistribution studies after intraperiton…

Coordinates in the Universe of Node-Negative Breast Cancer Revisited

2009

Abstract We present a global picture of the natural history of node-negative breast cancer in which two of three important biological processes have outstanding prognostic consequences. We propose that the transition from slow to fast proliferation of the tumor leads to the most dramatic aggravation of prognosis. Second, immune cell infiltration is of major importance to prevent disease progression in fast-proliferating breast carcinomas, regardless of estrogen receptor status. In the absence of endocrine treatment, steroid hormone receptor expression as a third axis is of limited prognostic importance. Dissecting tumors according to these three major biological axes will allow further unde…

A Synthetic MUC1 Anticancer Vaccine Containing Mannose Ligands for Targeting Macrophages and Dendritic Cells

2017

A MUC1 anticancer vaccine equipped with covalently linked divalent mannose ligands was found to improve the antigen uptake and presentation by targeting mannose-receptor-positive macrophages and dendritic cells. It induced much stronger specific IgG immune responses in mice than the non-mannosylated reference vaccine. Mannose coupling also led to increased numbers of macrophages, dendritic cells, and CD4+ T cells in the local lymph organs. Comparison of di- and tetravalent mannose ligands revealed an increased binding of the tetravalent version, suggesting that higher valency improves binding to the mannose receptor. The mannose-coupled vaccine and the non-mannosylated reference vaccine ind…

A comparison of two types of dendritic cell as adjuvants for the induction of melanoma-specific T-cell responses in humans following intranodal injec…

2001

Dendritic cells (DCs) elicit potent anti-tumoral T-cell responses in vitro and in vivo. However, different types of DC have yet to be compared for their capacity to induce anti-tumor responses in vivo at different developmental stages. Herein, we correlated the efficiencies of different types of monocyte-derived DC as vaccines on the resulting anti-tumor immune responses in vivo. Immature and mature DCs were separately pulsed with a peptide derived from tyrosinase, MelanA/MART-1 or MAGE-1 and a recall antigen. Both DC populations were injected every 2 weeks in different lymph nodes of the same patient. Immune responses were monitored before, during and after vaccination. Mature DCs induced …

Adoptive transfer of protective immunity from Cryptosporidium parvum-infected interferon-gamma and interleukin-12-deficient mice to naive recipients.

2008

We investigated the possibility of transfer immunity from Cryptosporidium parvum-infected interferon-gamma (GKO) and interleukin-12p40 (IL-12KO) deficient C57BL/6 mice to naive mice by transfer of intraepithelial lymphocytes (IELs) and CD4(+) T cells from spleen and mesenteric lymph nodes (MLNs). Three days after the transfer recipients were infected with C. parvum. IELs isolated from GKO donor mice after resolution of infection (day 15) but not at the peak of infection (day 8) significantly reduced the parasite load in recipient mice. In IL-12KO mice, IELs and also CD4(+) T cells isolated from the spleen and MLNs of donor mice at the peak of infection (day 5) and after resolution (day 15) …

Angioimmunoblastic T-cell lymphoma

2008

Angioimmunoblastic T-cell lymphoma (AITL) is a rare and aggressive neoplasm clinically characterized by sudden onset of constitutional symptoms, lymphadenopathy, hepatosplenomegaly, frequent autoimmune phenomena, particularly hemolytic anemia and thrombocytopenia, and polyclonal hypergammaglobulinemia. The lymph node histological picture is also distinctive, constituted by a polymorphic infiltrate, a marked proliferation of high endothelial venules, and a dense meshwork of dentritic cells. The neoplastic CD4+ T-cells represent a minority of the lymph node cell population; its detection is facilitated by the aberrant expression of CD10. Almost all cases arbor an EBV infected B-cell populatio…
