Intraoperative autologe Tumorzellvakzination in die Milz oder subcutan im Maus Tumormodell

Schürer, Susan 06 May 2015 (has links) (PDF)
In dieser Arbeit wurde in einem Maus Tumormodell untersucht, ob durch eine intraoperative Vakzination mit gentechnisch modifizierten autologen Tumorzellen ein antitumoraler Effekt erzielt werden kann. Das Experiment erfolgte mit zwei Tumorzelllinien (B16 Melanom und Lewis Lung Karzinom). Nach Implantation der Tumorzellen in C57/BL 6 Mäuse wurden diese chirurgisch entfernt. Intraoperativ erhielten die Mäuse eine Vakzination. Dazu wurden folgende Impfstoffe verwendet: 1. subletal bestrahlte mIL-12 transfizierte Tumorzellen, 2. subletal bestrahlte pRSC transfizierte Tumorzellen und 3. frostgeschockte Tumorzellen. Die Impfung erfolgte entweder subcutan oder direkt in die Milz. Es wurde die Hypothese aufgestellt, dass eine Injektion in die Milz und eine Modifikation mit IL-12 den besten Effekt erzielt. Eine Kontrollgruppe blieb ohne Vakzin. Beobachtet wurde das Tumorwachstum, der Zeitpunkt bis zum makroskopischen Wiederauftreten eines Tumors, Überlebenszeit und die Metastasierungsrate. Versuchstiere ohne Rezidivtumor erhielten erneut einen Tumor. Es erfolgte eine erneute Evaluation des Tumorwachstums, des Zeitpunktes bis zum makroskopischen Wiederauftreten eines Tumors, der Überlebenszeit und der Metastasierungsrate. In beiden Tumorzelllinien profitierten alle Therapiegruppen nach Tumorresektion und Vakzination bezüglich Tumorrezidivrate, Zeit bis zum makroskopischenWiederauftreten des Tumors, Überlebenszeit, Metastasierungsrate und Tumorwachstumsgeschwindigkeit gegenüber der Kontrollgruppe. Vereinzelt konnten signifikante Vorteile für die direkt in die Milz applizierte Vakzine bezüglich der Tumorwachstumsgeschwindigkeit aufgezeigt werden. Weiterhin ergab sich eine geringere Tumorrezidivrate, wenn IL-12 modifizierte autologe Tumorzellen nach R0 Resektion direkt in die Milz appliziert wurden. Auch nach Tumorreimplantation konnte bezüglich Überlebenszeit und Tumorwachstumsgeschwindigkeit ein Vorteil für alle Therapiegruppen gegenüber der Kontrollgruppe herausgearbeitet werden. Nach Impfung in die Milz zeigte sich tendenziell eine geringere Metastasierungsrate. Intraoperative autologe Tumorzellvakzinationen konnten im Tiermodell in einem adjuvanten Setting einen antitumoralen Effekt auslösen. Möglicherweise kann diese Art der Impfung eine zusätzlich hilfreiche Behandlungsform zu den bisherigen adjuvanten Chemotherapeutika werden.

Diagnostika a terapie mnohočetného myelomu / Multiple myeloma- diagnosis and treatment

Jungová, Alexandra January 2016 (has links)
Multiple myeloma is an agressive hemato-oncological disease the diagnosis and treatment possibilities of which have been developing for the last 15 years. The diagnostic methods include flow cytometry which uses antigen detection to distinguish between pathological and physiological plasmocytes. One of the monitored markers is marker CD45 which could be, according to our monitoring, of a negative prognostic value. 71 patients in our group were divided according to the intensity of CD45 antigen expression and the group with a lower expression showed a statistically higher risk of relapse within 12 months 62% vs. 25 % (p=0,0011). We did not find any connection with the influences of induction therapy or cytogenetics which are otherwise considered the most important prognostic markers. Multiple myeloma treatment involves a lot of combined protocols; and the repeated autologous transplantation is still considered to be the most efficient. We observed more positive results in planning the second autologous transplant early in patients who reached just partial remission after the 1st autologous transplant - significantly better TFS (treatment free survival) and overall survival (OS) were in the group of patients with early tandem transplantation: 18 months vs. 10 months (p=0.04) and the OS median was not reached...

Uso de enxerto autólogo de tecido mamário de mama contralateral em reconstrução de mama : uma nova abordagem

Oliveira, Leonardo D'Aló de January 2015 (has links)
A cirurgia de reconstrução de mama é uma ferramenta cirúrgica de importância ímpar para reparar os defeitos e assimetrias causadas pelos vários tipos de tratamentos cirúrgicos do Câncer de mama. Várias técnicas e táticas têm sido demosntradas e aplicadas nos últimos anos. Muitos são os estágios em que se encontram os pacientes e vários são os esquemas de abordagem terapêutica para diferentes estágios e tipos histológicos que se apresentam. Tratamentos quimioterápicos pré ou pós-operatório, tratamento radioterápico no pós-operatório quase imediato, mastectomias preventivas, setores amplos em diferentes quadrantes, quadrantectomias, todos estes são vários aspectos de tratamento de uma mesma patologia, porém com estágios e características histológicas e moleculares diferenciadas. Como alternativa cirúrgica para reconstrução de mama em câncer de mama, nos casos em que está indicada a quadrantectomia e/ou setor de mama, independentemente da localização na mama, é que propusemos uma técnica de uso de enxerto autólogo da mama contralateral para manter a forma e a simetria mamária associada a técnicas cirúrgicas de mamoplastias. Objetivo: O objetivo do presente estudo foi avaliar o uso de enxerto de mama contralateral associada a outras técnicas de cirurgia mamária já descritas por outros autores e acompanhar o resultado quanto à estética e simetria mamária no pós-operatório imediato e após o tratamento radioterápico. Comparar os resultados com as mamas do pré-operatório e avaliar a simetria e a estética no pós-operatório. Métodos: Foram incluídos neste estudo 42 pacientes com diferentes tratamentos, porém todas com indicação cirúrgica semelhantes: setor de mama ou quadrantectomia, seguidos de radioterapia. Todos os casos foram fotografados no pré-operatório e mais de 3 meses pós-tratamento radioterápico. Foi utilizada uma escala contínua para avaliar o grau de simetria mamária no pós-operatório de mais de 3 meses de radioterapia. A escalala de medição se baseou numa régua milimétrica de 0 a 10 cm. Foi solicitado a quatro especialistas na área para colocar uma marca na escala com relação à simetria e ao aspecto estético das mamas. As notas de cada paciente foram avaliadas estatisticamente. Resultados: Os resultados foram estatisticamente significativos para a avaliação estética e para a simetria mamária pós-cirurgia e radioterapia. Conclusão: Cocluímos que o enxerto autólogo de mama contralateral em cirurgia de reconstrução de mama é um procedimento que, quando utilizado com outras técnicas, traz um resultado estético e simétrico adequado, desta forma mostrando mais uma alternativa para cirurgia de reconstrução mamária. / Background: The Breast Reconstruction surgery is a surgical tool of unparalleled importance to repair the defects and asymmetries caused by various types of surgical breast cancer treatment. Various techniques and tactics has been demonstrated and applied in recent years. Many patients are at different stages of the disease and several are the sorts of therapeutic approaches for different stages and histologic types that feature. Neo adjuvant chemotherapy treatments or postoperative chemotherapy, radiotherapy in almost immediately after surgery, preventive mastectomies, removing large breast tissue in different quadrants, quadrantectomies. All these are various aspects of treatment of the same disease however to different stages and histological and molecular characteristics. As a surgical alternative to breast reconstruction in breast cancer, where it is indicated quadrantectomy and or wide resection of breast tissue in the same quadrant, regardless of location in the breast that I proposed a technique contralateral breast grafiting replacement to keep shape and breast symmetry. Objetive: The aim of this study was to evaluate the contralateral breast graft associated with other breast surgery techniques already described by other authors, and follow the aesthetic result in the immediate postoperative period and after three months of radiotherapy. Compare the results with those of preoperative breast, and evaluate the symmetry postoperatively and proper aesthetic result. Methods: The study included 42 patients. Each case with different proposals for treatment, but all with similar surgical indication, wide resection of the breast or quadrantectomy, followed by radiotherapy. All cases were photographed in their preoperative, “pre radiotherapy” and three months post radiotherapy. A continuous scale was used to assess the degree of mammary symmetry in these patients in the post operative period of three months after radiotherapy. The measurement was based on a rule millimeter scale from 0 to 10 cm. We were asked to four experts in the field to put a mark on the scale with respect to symmetry and aesthetic appearance of the breasts. The scores of each patient were evaluated statistically. Results: The results were statistically significant for the aesthetic evaluation of the breasts and also for evaluation of the symmetry of the breasts after surgery and radiotherapy. Conclusion: We concluded that autologous graft contralateral breast in breast reconstruction surgery is a procedure that when used with other techniques, brings an aesthetic and suitable symmetrical result thus showing an alternative to breast reconstruction surgery.
