1. 16. Type IV collagen in breast and colorectal cancer : a potential biomarker of metastatic disease

   Författare :Moa Lindgren; Hanna Nyström; Ingrid Ljuslinder; Malin Sund; Kristian Pietras; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Colorectal cancer; colorectal liver metastases; breast cancer; breast cancer metastases; tumor marker; biomarker; stroma; type IV collagen;

   Sammanfattning : Background: Metastatic colorectal cancer (mCRC) and metastatic breast cancer (mBC) are two leading causes of cancer-related mortality worldwide. Early detection of metastatic disease is critical, and sensitive, easily accessed and cost-effective biomarkers that can diagnose mBC and mCRC at an early stage would have high clinical value.

3. 17. Radiation therapy of upper gastrointestinal cancers with scanned proton beams : A treatment planning study

   Författare :Gracinda Mondlane; Albert Siegbahn; Michael Gubanski; Iuliana Toma-Dasu; Crister Ceberg; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Treatment planning; gastric cancer; liver metastases; photon beam therapy; proton beam therapy; dosimetric comparison; normal tissue complication probability; risk of radiation-induced secondary cancer; patient selection; Medical Radiation Physics; medicinsk strålningsfysik;

   Sammanfattning : Proton beam therapy (PBT), using scanned beams, is an emerging modality used for the treatment of cancer. The clinical advantages of PBT, compared to commonly used photon beam therapy, have been demonstrated in different studies. LÄS MER

4. 18. Comparative study of Radiation Therapy of Targets in the Upper Abdomen with Photon- or Scanned Proton-beams

   Författare :Gracinda Mondlane; Albert Siegbahn; Michael Gubanski; Iuliana Toma-Dasu; Crister Ceberg; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; photon radiotherapy; proton beam radiotherapy; gastric cancer; liver metastases; Medical Radiation Physics; medicinsk strålningsfysik;

   Sammanfattning : Recently, there has been an increase in the number of proton beam therapy (PBT) centers operating worldwide. For certain cases, proton beams have been shown to provide dosimetric and radiobiological advantages when used for cancer treatment, compared to the regular photon-beam based treatments. LÄS MER

5. 19. Dosimetric effects of breathing motion in radiotherapy

   Författare :Anneli Edvardsson; Lund Medicinsk strålningsfysik; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; radiotherapy; breathing motion; DIBH; interplay effects; VMAT; proton therapy; breast cancer; Hodgkin’s lymphoma; liver; dosimetry; treatment planning; medical physics;

   Sammanfattning : The goal of radiotherapy is to deliver a homogeneous high dose of radiation to a tumour while minimising the dose to the surrounding healthy tissue. To achieve this, increasingly advanced treatment techniques, such as volumetric modulated arc therapy (VMAT) and proton therapy, have been developed. LÄS MER

7. 20. Colorectal Liver Metastases – Different Aspects on Treatment with Associated Liver Partition and Portal Vein Ligation for Staged Hepatectomy and on Portal Vein Occlusion

   Författare :Kristina Hasselgren; Bergthor Björnsson; Per A Sandström; Tommy Sundqvist; Per Lindner; Linköpings universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

   Sammanfattning : Introduction: For patients with colorectal liver metastases (CRLM), the only treatment with a possibility for long-term survival and cure is radical resection. The majority of patients are at the time of diagnosis not assessed as resectable because they have advanced disease in the liver or unresectable extrahepatic disease or are too frail to withstand liver surgery.
