This literature study aims to examine the existence of cancer stem cells in breast cancer. The cancer stem cell theory states that there is a hierarchical organization within a tumour, in which a small subpopulation of the cells can initiate new tumours and maintain tumour growth whilst the bulk of the tumour cannot. These tumour initiating cells have shown to possess many characteristics similar to those of adult stem cells, which is why they are often referred to as cancer stem cells. Both cell types have the capacity of asymmetric division and have shown to possess mechanisms of resistance to both apoptosis and cancer drugs. The cancer stem cell theory elucidates many biological aspects such as the heterogeneity of tumours and the relapse of many cancers after what appeared to be successful treatments.

Background. Immunohistochemistry is a useful method in the differential diagnosis between pleural mesotheliomas and metastatic adenocarcinomas in the pleura. Cytokeratin 20 and 7 have been used successfully as markers in studies determining primary location of adenocarcinomas from metastases. The current study is a complementary research of archived paraffininbedded material of cases with cancer origin. This study contributes a bigger statistical material that may facilitate the search for unknown primary site of adenocarcinoma by identification of metastatic cells in the pleura.Methods.

This essay is about the hamlets´ older boundaries, i.e. boundary lines (?rågångar?) and boundary markers in the form of rocks, and an own survey of two hamlet boundaries in southeast Sweden. Many of the boundary rocks were subjected to unintentional damage or destruction that arose during forestry activities, the excavation of ditches, or road construction. Boundaries between hamlets sparsely populated areas were not clearly defined from the beginning, but were established initially in the form of boundary zones, that often consisted of wetlands, watercourses, or mountain heights.

The female dog has a unique reproductive endocrinology, with high levels of progesterone throughout the 70-day long luteal phase. In this project, markers of glucose metabolism were studied and compared from the aspects of breed group and time in oestral cycle. The parameters studied were: glucose, insulin, progesterone, fructosamine and the newly introduced analysis of HbA1c. Hba1c was also further evaluated and discussed as a diagnostic tool in canine medicine.No differences in terms of glucose markers were found between a group of purebreed dogs of various breeds compared to a group of dogs with high risk of dioestrus diabetes, namely the Norwegian and Swedish elkhounds.No differences were found between the two sample occasions, anoestrus and dioestrus, concluding that there is no need for relating test results to the time of the oestrous cycle in middle-aged intact female dogs.There were statistically significant higher values of all glucose markers in diabetic dogs than in non-diabetic dogs. When it came to HbA1c, however, there was a larger overlap between the two groups, compared to fructosamine.

Bakgrund: Cancer är något som berör många människor. Det räknas med att var tredje svensk under sin livstid kommer att drabbas av en cancersjukdom. Cancer är vanligast bland äldre människor, omkring två tredjedelar är över 65 år när diagnosen ställs. Syfte: syftet med studien var att beskriva hur cancer påverkar livskvaliteten hos människor. Me-tod: Studien är en litteraturstudie som baseras på åtta vetenskapliga artiklar med kvalitativt och delvis kvantitativt innehåll.

Today, some kind of laboratory results is required for around 70% of the diagnostics and follow-ups for diseases. In many of the cases the time from sampling to a result is very critical. Therefore the discussion of how to improve this situation has begun. For many analyses serum has been the routine choice for a long time but now it is disputed. After blood collection in a serum tube it is essential to wait 30-60 minutes before centrifugation and analysis of the sample, a long time for someone in an acute state.

Every year 300 children in Sweden are diagnosed with cancer, but through research and successful clinical work 70 % of the children survive their cancer. Aim: To illuminate nursing care of children with cancer. Method: The study was carried out as a general literature study through systematic review and analyse of 18 scientific articles. Result: The analysis resulted in five themes: Support, play as a psychological assistance, alternatives to alleviation of pain, nutrition and relieving symptoms of fatigue.Conclusion: It is important that the nurse has knowledge about the children and their family?s experiences when dealing with a cancer illness to provide the children with adequate care.

Cirka 300 barn per år i Sverige insjuknar i cancer. Upplevelsen av att ens barn diagnostiseras och behandlas för cancer är något av det svåraste som kan drabba en förälder. Barn får andra former av cancer än vuxna och behandlingen är ofta lång och påfrestande. I sjuksköterskans ansvarsområde ingår att ha en dialog med patient och närstående samt att ge stöd under behandlingen. Genom att sjuksköterskan stödjer föräldrarna under barnets behandling ger det föräldrarna möjlighet till att på bästa möjliga sätt ta hand om sitt barn.Syftet med studien var att beskriva föräldrars upplevelse av stöd från sjuksköterskan under tiden då deras barn behandlades för cancer..

Lung cancer is a disease which patients experience stigma in society and in care. This is because lung cancer is often seen as a self-inflicted disease. The stigma surrounding lung cancer is due to the strong relationship with smoking and have been shown to have a negative impact on the perceived health. The purpose of this study was to illuminate experiences of stigma for patients with lung cancer. The literature review was based on 11 scientific articles.

Bakgrund: Att genomgå behandlingar vid hematologisk cancer innebär en stor omställning i det dagliga livet. Symtom och biverkningar har en stor påverkan på kropp och själ. Hematologisk cancer innefattar olika typer av cancer: leukemi, lymfom och myelom. Den behandling som ges vid hematologisk cancer innefattar stamcellstransplantation, strålning och cellgifter. Syfte: Syftet med denna studie var att beskriva patienters upplevelser av behandlingar vid hematologisk cancer.

Year 2004 nearly 1000 new cases of oral cancer were diagnosed in Sweden. An early discovery increases the chances for survival remarkably. The dental profession has an important role in detecting oral cancer. Considering that dental hygienists probably will have a greater responsibility in the future when it comes to examinations, knowledge of oral cancer will be important for this profession. The aim of this study was to examine the dental hygienists knowledge of Oral Cancer in the county of Blekinge, Kalmar and Kronoberg, as well as their experiences in detecting oral cancer.

Bakgrund: Cancer är en sjukdom som drabbar 48 600 personer i Sverige. Av dessa väljer 50-70 % att vårdas palliativt i sitt hem. De patienter som vårdas palliativt har behov av en bra symtomlindring och god kommunikation med vårdpersonal. Syfte: Syftet med studien var att undersöka vilka behov patienter med cancer har som vårdas palliativt i hemmet. Metod: Metoden som använts var en litteraturstudie.

The aim of this study is to describe teenagers' experience of being diagnosed with cancer. A cancer diagnosis very dramaticaly changes the lives of a teenager and its relatives. Cancer is a loaded word that most people associate with death and the teenager and its relatives generally react with despair and anxiety towards. Adolescence is a very emotionally difficult period with many physical and psychological changes, and it is therefore particularly difficult to suffer from a serious illness like cancer during this period. The method used when conducting this study is qualitative content analysis of various blogs written by teenagers living with cancer and resulted in six categories.

Narratives about life-changing events like cancer have become more common in today?s society. The purpose of the present study was to investigate whether gender patterns in society can also be found in pathographies about cancer, and further to investigate how gender is expressed in these cancer related narratives. Questions were posed on characteristics of the autobiographical cancer narratives, how gender is constructed by the authors of these narratives, and what these narratives say about gender structures? liability to change in the individuals affected by this disease.
