Laparoscopic lymph node dissection should be performed before fertility preserving treatment of patients with cervical cancer

2012

Objective: The aim of this study is to assess our results of treatment of women with stage I cervical cancer > 2 cm in diameter seeking fertility preservation. Treatment consisted of Laparoscopic Pelvic and Paraaortic Lymphadenectomy (LPPLND), and when no nodal metastasis was detected, neoadjuvant chemotherapy (NACT) followed by radical vaginal trachelectomy (RVT). Patients with positive lymph nodes underwent primary chemoradiation. Methods: A cohort of women younger than 40 years of age with stage I disease > 2 cm who underwent LPPLND and either NACT and RVT or chemoradiation. Oncological outcome was evaluated prospectively. Results: Eighteen women were eligible for this study. Twelve (67%…

Clinical Recommendation Radical Trachelectomy for Fertility Preservation in Patients With Early-Stage Cervical Cancer

2012

Radical trachelectomy (RT) is a fertility-sparing procedure with the aim to provide adequate oncological safety to patients with cervical cancer while preserving their fertility. In the current review, indications, development of the procedure, technical aspects, preoperative and postoperative management, and oncological, fertility, and obstetric outcomes are discussed and studied with respect to whether the procedure is performed abdominally or vaginally. Complications of RT, staging, and more conservative alternatives to RT are discussed as well. A systematic MEDLINE search was performed, which yielded 218 articles, of which 75 were selected for further analysis based on the number of pat…

mRNA Vaccination and Personalized Cancer Therapy

2014

Nucleic acid vaccines link two prerequisites for success, namely, the delivery of molecularly defined antigens as vaccine targets of interest and an inherent adjuvant activity. As compared to DNA-based approaches, in vitro-transcribed messenger RNA (mRNA) is a safer drug format due to the adjustable, transient expression and lack of genomic integration. In contrast to viral vector vaccines, mRNA vaccination is not limited by the emergence of immune responses against antigens produced by the viral vector backbones. Thus, mRNA vaccines are particularly attractive for cancer immunotherapy for which induction of clinically meaningful antigen-specific immune responses depends on repeated immuniz…

The Role of Self-Assembling Lipid Molecules in Vaccination

2018

Abstract The advent of vaccines represents one of the most significant advances in medical history. The protection provided by vaccines has greatly contributed in reducing the number of cases of infections and most notably to the eradication of small pox. A large number of new technologies and approaches in vaccine development are currently being investigated with the goal of providing the basis for the next generation of prophylactics against an ever-expanding list of emerging and reemerging pathogens. In this chapter, we will focus on the role of lipids and lipid self-assembling vesicles in new and promising vaccination approaches. We will start by describing how lipids can induce activat…

Initiation of adaptive immune responses by transcutaneous immunization.

2007

The development of new, effective, easy-to-use and lower-cost vaccination approaches for the combat against malignant and infectious diseases is a pre-eminent need: cancer is a leading cause of morbidity in the Western World; there are numerous pathogenic diseases for which we still have no protective or therapeutic cure; and the financial limitations of developing countries to fight these diseases. In this mini-review we focus on transcutaneous immunization (TCI), a relatively new route for antigen delivery. TCI protocols appear to be particularly promising by gaining access to skin resident APC, which are highly efficient for the initiation of humoral and/or cellular immune responses. Con…

Plaušu audzēja klīniski morfoloģiskais raksturojums

2017

Plaušu vēzis ir pirmā vieta mirstības ziņā gan vīriešiem, gan sievietēm pasaulē un Latvijā. Liela daļa slimības gadījumu tiek atklāta vēlīnās stadijās, kas pasliktina pacientu prognozi. Katru gadu Latvijā saslimst ap 1000 cilvēku un nomirst tik pat daudz. Mūsdienu klīniskajā onkoloģijā NSŠPV (Nesīkšūnu plaušu vēža) agrīnas stadijas ārstēšanā ir svarīgi izvērtēt pacienta riska faktorus, kuri ietekmē pacienta kopējo dzīvildzi un recidīva risku, un izvēlēties atbilstošo terapiju katram pacientam. NSŠPV agrīno stadiju galvenā ārstēšanas metode ir ķirurģiska rezekcija un atkarīgi no klīniskas un patoloģiskas stadijas tiek nozīmētā adjuvanta terapija. Plakanšūnu karcinomas pacientiem pēc ķirurģis…

Influence of the stereochemistry and of the functionality of organic molecules on the hydration of cementitious compounds

2015

The current limited knowledge on the interactions between organic admixtures and mineral phases as well as their influence on the hydration mechanisms of the Ordinary Portland Cement (OPC) represents a real limitation in the development of new organic products with improved and controlled properties. Here, this study intended to understand why and how organic admixtures modify the setting time of OPC by progressively varying the characteristics of simple organic molecules such as their charge, functional groups (hydroxyl, hydroxy-carboxylate, carboxylate, sulfonate and phosphonate) and the stereochemistry of their hydroxyl groups.The different retardations induced by the organic molecules s…

Effects of adjuvants of the cholera toxin family on CD4 + T cell responses in a murine model of intrarectal immunization with rotavirus-like particles

2011

Mucosal immunization is an important goal of vaccine development to protect against pathogens that use mucosa as portals of entry. However, the use of non-replicating antigens requires the addition of adjuvants.Cholera-like enterotoxins, cholera toxin (CT) from Vibrio cholerae and the heat-labile enterotoxin (LT) from toxinogenic strains of E. coli, as well as the mutant LR-192G and their B subunits (CTB and LTB) have been shown to increase immune responses against unrelated co-administered antigens by mucosal routes. However, their mechanism of action is very complex and not completely understood and differences exist between holotoxins and B subunits and within molecules, differences exis…

Retrospektīvs pētījums par dzīvildzi resnās zarnas vēža II stadijā, atkarībā no ārstēšanas stratēģijas

2017

Ievads: Adjuvanta ķīmijterapija pacientiem ar diagnosticētu II (UICC) stadijas resnās zarnas vēzi ir apsverama. Pacientu dalījums augsta un zema riska grupās, palīdz izlemt, vai pēc ķirurģiskas ārstēšanas ir indicēta ķīmijterapija, lai gan dzīvildzes ieguvumi nav ne plaši pētīti, nedz arī pierādīti. Tāpēc, autora mērķis šajā pētījumā bija salīdzināt piecu gadu dzīvildzi UICC II stadijas resnās zarnas vēža pacientiem, kuri saņēma adjuvantu ķīmijterapiju, un pacientiem, kuri ķīmijterapiju nesaņēma. Metodes: Dati par pacientiem ar II stadijas resnās zarnas vēzi, tika iegūti Paula Stradiņa Klīniskās universitātes slimnīcā Rīgā, Latvijā, Onkoloģijas klīnikā. Diagnozes apstiprināšanas laiks no 20…
