- Patients with ATM (Ataxia-Telangiectasia mutated) mutation show increased sensitivity to radiation and have a higher risk of developing malignancies. The present study aimed to investigate whether ATM expression was related to radiotherapy, and clinicopathological and biological variables in rectal cancers. ATM expression was immunohistochemically examined in 78 rectal cancers from patients who participated in a Swedish rectal cancer trial of preoperative radiotherapy. Of 78 patients, 44 underwent surgery alone, and 34 underwent both preoperative radiotherapy and surgery. Fifty-eight cases had normal rectal mucosa adjacent to the tumour. The results showed that, compared to normal mucosa, tumours had less nuclear (p=0.03) but more cytoplasmic expression of ATM (p=0.004). In tumours, less expression of ATM, either in the nucleus (p=0.07) or in the cytoplasm (p=0.02 for staining intensity, and p=0.07 for staining percentage), tended to be correlated with male patients. Also, ATM expression was not related to radiotherapy or other clinicopathological and biological variables (p > 0.05). In conclusion, the pattern of ATM expression was changed from normal mucosa to tumour. Less expression of ATM may be related to males.

- Purpose: To evaluate the role of particularly interesting new cysteine-histidine-rich protein (PINCH) in corneal wound healing and early neovascularization and to assess the influence of granulocytes. Methods: A standardized corneal alkali wound was inflicted under general anaesthesia to the right eye of 14 New Zealand White rabbits. Seven of the rabbits received i.v. 5 mg/kg fucoidin every 2 hours to prevent granulocytes from entering the wound area. After 36 hours, the rabbits were killed, the corneas excised, fixed in 4% formaldehyde and embedded in paraffin. The sections were double-stained with antibodies against PINCH and with haematoxylin. Results: In the normal cornea and limbus, PINCH was weakly expressed in the corneal epithelium and in a wedge of the conjunctival stroma. In the wounded corneas, PINCH expression was seen in the frontline of repopulating endothelial and epithelial cells, and in active keratocytes. The vascular endothelium and the granulocytes expressed PINCH, as did the conjunctival epithelium. In the fucoidin-treated rabbits, PINCH expression was markedly reduced. The vascular endothelial cells and the few granulocytes did not express PINCH in these rabbits. Conclusions: PINCH is only slightly expressed in the normal cornea. A corneal wound induces PINCH expression in the repopulating cells, in the vascular endothelial cells of the limbus, in the limbal epithelium and in the granulocytes. Exclusion of granulocytes reduces expression of PINCH and there is no expression at all in the vascular endothelium. © 2007 The Authors Journal compilation 2007 Acta Ophthalmol Scand.

- Psoriasis is an inflammatory skin disorder affecting approximately 3% of the population. Genetic studies published so far have shown a complex genetic inheritance with heterogeneity and a putative major susceptibility locus in the HLA region on chromosome 6. We have collected a large amount of material consisting mostly of small nuclear families in order to perform a genome-wide scan for psoriasis-associated genes. In order to focus the scan properly on possible candidate regions, we performed a cytogenetic analysis of 477 unrelated psoriatics. We divided our findings into sporadic, affecting a minor fraction of the cells, and constitutional, i.e. they were present in all cells examined. We found three cases of balanced translocation, all of which involved chromosome 11q. Two of these had a breakpoint in q12-13, whilst one involved the telomeric part of chromosome 11q. In order to characterise further the breakpoint on 11q12-13, we used bacterial artificial chromosomes (BACs) analysed by fluorescent in situ hybridisation (FISH). We were able to show that the persons had a close, but not identical breakpoints; they were separated by at least 5 cM. The major atopy locus is located in this region, as well as a locus for insulin-dependent diabetes mellitus, both being conditions with a pathogenetic mechanism involving antigen presentation.

- Purpose. The aim of this study was to get a deeper understanding into how adults with cerebral palsy (CP) experience physiotherapy and physical activity in a perspective from childhood to adulthood; and how personal and environmental factors influence possibilities for physiotherapy and physical activity. Method. Data was collected through interviews with 22 community-living adults (35-68 years) with CP, from five counties in Sweden. The questions were open-ended and the interviews were taped and transcribed to written language. The material was analysed through qualitative content analysis, a classification process resulting in different themes. Results. The narratives from the 22 informants, based on experiences from childhood to adulthood, resulted in a description of prerequisites for carrying out physiotherapy and physical activity. Five different themes were identified: (i) Being enjoyable, (ii) Giving effects, (iii) Being comprehensible, (iv) Being integrated in daily life, and (v) Supportive healthcare with competent professionals. Conclusion. The information from the interviews elucidates the importance of a lifelong support from healthcare professionals. Physiotherapists with attentiveness to different life situations in combination with good understanding and knowledge in CP could facilitate continuous physical activity in people growing up and ageing with CP.

- Background Toxicity during chemoradiotherapy (CRT) in cervical cancer patients might limit the chances of receiving an optimal treatment and to be cured. Few studies have shown relationships between acute side effects and patients age. Here, the association between age and acute side effects such as nausea/vomiting, diarrhea and weight loss during CRT was analysed in cervical cancer patients.MethodsThis study included 93 patients with primary cervical cancer stage IBI to IVA who received CRT from 2013 to 2019. The frequency of symptoms/toxicity grade was analysed by using the Common Terminology Criteria for Adverse Events (CTCAE) version 5.0.ResultsPatients ≥ 52 years had a significantly higher frequency of nausea/vomiting and increased grade ≥ 3 toxicity during CRT compared to younger patients (p<0.001, p = 0.001). Toxicity grade ≥ 3 of nausea/vomiting was associated with increased frequency of weight loss (p = 0.001), reduced ADL (p = 0.001) and dose modifications of both radiotherapy (RT) (p = 0.020) and chemotherapy (CT) (p = 0.030) compared to toxicity grade 2. The frequency of diarrhea (p = 0.015) and weight loss (p = 0.020) was higher in older patients compared to younger.Conclusions Older patients have an increased risk of acute side effects as nausea/vomiting, diarrhea and weight loss. Age could be useful in predicting acute side effects in primary cervical cancer patients with CRT.

Biological and histological factors as predictors in rectal cancer patients : A study in a clinical trial of preoperative radiotherapy
- 2011
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- With improved surgical techniques and preoperative radiotherapy (RT) the local recurrence rate in rectal cancer patients has been reduced, however the mortality rate is still high and there is a huge variation in the response to preoperative RT in patients with the same tumour stage. To improve patient’s survival, it is of great importance to identify good prognostic and predictive factors that help us to select the best suited patients for preoperative RT in the future.For many years, studies of neoplastic transformation have mainly focused on tumour cells. In recent years, researchers have realised that the stroma around tumour cells and their extracellular matrix components also play an important role in tumour carcinogensesis.The aim of this thesis was to investigate the biological factors, survivin and particularly interesting new cysteine-histidine rich protein (PINCH), histological factors, inflammatory infiltration, fibrosis, necrosis, mucinous content, angiogenesis and lymphangiogenesis as well as their relationships to preoperative RT and to clinical variables in rectal cancer patients who participated in a Swedish rectal cancer trial of preoperative RT.In paper I, the expression of survivin and its relationship to preoperative RT and clinical factors were investigated in 98 primary rectal tumours and adjacent normal mucosa. In all patients, positive survivin expression was independently related to worse survival compared to negative survivin expression in a multivariate analysis.In paper II, PINCH expression and its relationship to RT, clinical, histological and biological factors were investigated at the invasive margin and inner tumour area in 137 primary rectal tumours and in cell line of fibroblasts. In patients without RT, strong PINCH expression was independently related to worse survival in a multivariate analysis. No survival relationship was found in the patients with RT, and there was no difference in PINCH expression between the subgroups of non-RT and RT at the invasive margin/inner tumour area. In patients with RT, strong PINCH expression at the inner tumour area was related to a high level of lymphatic vessel density (LVD).In paper III, the frequency of LVD/blood vessel density (BVD) was analysed at the periphery, the inner tumour area and the invasive margin of 138/140 primary rectal tumours and correlated to RT, clinical, histological and biological factors. In all patients, LVD at the periphery of the tumour was independently related to better survival compared to LVD at the inner tumour area/invasive margin. In all patients, a higher LVD at the periphery was related to negative (wild type) p53 expression.In paper IV, the inflammatory infiltration, fibrosis, necrosis and mucinous content were studied in relation to RT, clinical and biological parameters in preoperative biopsies (n = 153) and in primary tumours (n = 148). In all patients and in the subgroups of non-RT and RT a higher grade of inflammatory infiltration was independently related to improved survival compared to weak inflammatory infiltration in a multivariate analysis.In this thesis, survivin, PINCH, LVD and inflammatory infiltration are independent prognostic factors in rectal cancer patients who participated in a clinical trial of preoperative RT. This information may help us to improve patient’s survival by selecting the best suited patients for preoperative RT in the future.

- Purpose Radiotherapy (RT) causes an inflammatory reaction of the tissue which leads to fibrosis and reduced functioning of the pelvic organs. Few studies have shown significant relationships between side effects and RT in uterine tumors. Here, the urological, lymphedema, pelvic pain and gastrointestinal (GI) symptoms were studied before and after RT in patients with primary uterine tumors using the EORTC QLQ-EN24, specifically designed for uterine cancer patients. Methods This prospective cohort study comprised patients with primary uterine tumors who received pelvic radiotherapy (RT). A total of 43 patients were included from May 2014 to February 2019. Patients completed the questionnaires for global health status and functioning before the start of RT and at 3 and 12 months after RT. Results We found a significant worsening of the urological symptoms 3 months after RT which persisted up to 12 months after RT compared to baseline values prior to start of RT (p = 0.007). An exacerbation of the urinary symptoms was seen in patients with vaginal brachytherapy/boost compared to patients with pelvic RT at 12 months after RT (p = 0.053). The severity of lymphedema symptoms increased from RT start to 12 months after RT (p = 0.019) and the pelvic pain were higher at 3 months after RT compared to before RT (p = 0.004). Also, the level of GI symptoms was significantly higher 12 months after RT compared to the RT start (p < 0.001). Conclusions The urologic, lymphedema, pelvic pain and GI symptoms all increase after RT.

- Particularly interesting new cysteine-histidine rich protein (PINCH), involved in cell spreading, motility and proliferation, has been shown to enhance radioresistance in colon cancer cell lines. The expression of PINCH in relation to radiation was studied in co-cultured colon cancer cells. Furthermore, the clinical significance between PINCH and radiotherapy (RT) was analyzed in rectal cancer patients with or without RT. The relative PINCH expression in colon cancer (KM12C) cells cultured separately and in co-culture was examined by western blotting and real-time PCR, and was analyzed over a period of 8 and 24 h after radiation. PINCH expression was immunohistochemically examined in 137 primary rectal tumors for which 65 cases did not receive RT and 72 cases received RT. PINCH expression tended to decrease from that in the separately cultured KM12C cells without radiation to that in cells with radiation at 8 h (P=0.060); while in the co-cultured cells, no significant difference was found (P=0.446). In patients with RT, strong PINCH expression was related to worse survival, when compared to patients with weak expression, independent of TNM stage, degree of differentiation, age and p53 status (P=0.029, RR 4.03, 95% CI 1.34-12.1). No survival relationship for the patients without RT was observed (P=0.287). A statistical interaction analysis between PINCH, RT and survival showed a trend towards significance (P=0.057). In conclusion, PINCH predicts survival in rectal cancer patients with RT, but not in patients without RT. The expression of PINCH may be regulated by radiation and by environmental factors surrounding the cells.
