- The incidence of pancreatic cancer has fallen during the last ten years in Sweden. Early signs and symptoms of the disease are still undiscovered and when diagnosis is made the disease is incurable in most patients. Transabdominal ultrasonography is the first-line imaging test followed by spiral computed tomography (CT) and magnetic resonance imaging (MRI) if required for definite diagnosis. Spiral CT is also the imaging test of choice for assessment of resectability of the tumor. Surgical removal of the tumor is the only chance of cure. Markedly improved hospital mortality after pancreaticoduodenectomy is reported and an association between hospital volume and outcome of the operation has been established. Longterm survival after attempted curative resection continues to be dismal, however. Adjuvant treatment should not be given outside clinical studies. Palliative treatment has improved thanks to progress in the field of endoscopy, interventional radiology and in management of pain and nutrition. Palliative chemotherapy should only be given selectively outside clinical studies. Radiotherapy has no proven effects on survival. Special pancreatic cancer treatment teams with catchment areas of 2-4 million inhabitants are recommended by international authorities.

Journal article (other academic/artistic)abstract
- Transabdominellt ultraljud är förstahandsundersökning vid misstänkt pankreascancer, följt av spiral-DT eller MR för mer definitiv diagnos. Tumörmarkörer har ingen plats i rutindiagnostiken. Spiral-DT är basen i resektabilitetsbedömningen. Resektion av tumören är en förutsättning för bot. Ett samband har påvisats mellan antalet resektioner som görs vid ett sjukhus årligen och postoperativ mortalitet. Långtidsöverlevnaden efter resektion är oförändrat kort medan postoperativ mortalitet minskat dramatiskt vid enheter som rapporterat sina resultat. Adjuvant behandling efter resektion bör endast ges inom ramen för kliniska studier. Det palliativa omhändertagandet har förbättrats främst genom utveckling inom endoskopi, interventionell radiologi, smärt- och nutritionsbehandling. Palliativ cytostatikabehandling bör endast ges selektivt utanför kliniska studier. Radioterapi har ingen dokumenterad effekt på överlevnaden vid icke-resektabel pankreascancer. Internationellt rekommenderas speciella behandlingsteam för pankreascancer med tillräckliga upptagningsområden (2–4 miljoner invånare).

Heat shock protein 70 (HSP70) after laser thermotherapy of an adenocarcinoma transplanted into rat liver.
- 2003

Journal article (peer-reviewed)abstract
- The heat shock proteins (HSPs) HSP70 and gp96 from necrotic tumour cells are considered to function as chaperones in presenting tumour antigens. We therefore studied HSP70 and immune cells in a transplantable carcinoma in the liver of rats after interstitial laser thermotherapy (ILT). Experiments were performed in Wistar FU rats using a dimethyl-hydrazine-induced adenocarcinoma implanted into the left lateral lobe of the liver. Rats were randomized to one of the following groups: a) ILT of tumour, b) sham ILT, or c) control. ILT was suboptimal and was performed at a steady-state temperature of 43 degrees C at the tumour margin for 30 minutes. Rats were killed 15 minutes, 5 hours, 10 hours, 15 hours or 12 days after treatment. Double immunohistochemistry was performed for HSP70 and ED1 macrophages or CD8 lymphocytes, and ELISA for serum concentrations of HSP70. After ILT, there was an increase of HSP70 immunoreactivity in tumours as compared to sham ILT. At the same time, tumour cells affected by ILT showed a shift of HSP70 from the cytoplasm to the nucleus with a peak at 10 hours. Few CD8-positive cells were found. There was an increase of tumour-infiltrating ED1 macrophages after ILT as compared to sham ILT at 10-15 hours after treatment. HSP70 was present in ED1 macrophages significantly more frequently after ILT than after sham ILT, and this was true both for HSP70 localized to the surface and the cytoplasm of the macrophage. There was a significant increase in serum HSP70 during the first 15 hours after ILT. In conclusion, laser thermotherapy resulted in increased HSP70 immunoreactivity within tumours and HSP70 shifts from cytoplasm to nucleus. Furthermore, it resulted in increased numbers of tumour-infiltrating macrophages and an increased presence of HSP70 in the membrane and cytoplasm of these macrophages.

Extended operation with or without intraoperative (IORT) and external (EBRT) radiotherapy for gallbladder carcinoma.

Journal article (peer-reviewed)abstract
- BACKGROUND/AIMS: Gallbladder carcinoma is a rare disease with dismal prognosis. However, lately improved survival has been reported after extended operation including liver resection and lymphadenectomy in addition to cholecystectomy. The aim of this study was to evaluate such a surgical strategy with and without adjuvant intra- and postoperative radiotherapy (IORT/EBRT). METHODOLOGY: 20 patients underwent extended operation and the last 10 of them IORT/EBRT in addition. Tumor staging was done using the TNM system, determination of histological tumor differentiation and immunohistochemical assessment of p53, Ki67, metallothionein, deleted in colorectal cancer and carcinoembryogenic antigen in tumor tissue. RESULTS: There was no hospital mortality. Postoperative complications occurred in 3 patients (15%). Actuarial 5-year survival was 47% in the radiotherapy group and 13% after operation only (NS). The corresponding figures for median survival are 28.8 and 20.2 months, respectively. Five patients are still alive in the radiotherapy group. There was no difference in tumour stages of the two groups irrespective of the way of evaluation. CONCLUSIONS: The results suggest that extended operation for gallbladder carcinoma +/- IORT/EBRT can be done safely. The tendency to longer survival after adjuvant radiotherapy was not statistically significant.

Interstitial laser hyperthermia of a rat liver adenocarcinoma

Journal article (peer-reviewed)abstract
- The aim of this study was to compare interstitial laser thermotherapy with excision of a liver tumour. A dimethylhydrazine-induced adenocarcinoma was implanted into the left lateral lobe of the rat liver, and treatment was performed 8 days later. Rats were treated with resection of the tumour-bearing lobe or underwent interstitial laser thermotherapy, which was performed at a steady-state temperature of 46°C for 30 min, 3 mm from the tumour margin. The incidence and extent of intraperitoneal spread was smaller after laser thermotherapy than after resection, with no difference in local control. Using inoculation of tumour cell suspensions into the lateral and the median lobes of the liver simultaneously and treating the lateral lobe tumour only, we found that laser thermotherapy reduced take and growth of the untreated tumour in the median lobe indicating that laser thermotherapy may induce immunologic effects. It is concluded that interstitial laser thermotherapy reduces spread of liver tumour as compared to resection. It is suggested that this can be at least partly explained by a laser-induced immunologic effect.
