- Laparoscopic surgery for colon cancer is associated with improved recovery and similar cancer outcomes at 3 and 5 years in comparison with open surgery. However, long-term survival rates have rarely been reported. Here, we present survival and recurrence rates of the Dutch patients included in the COlon cancer Laparoscopic or Open Resection (COLOR) trial at 10-year follow-up. Between March 1997 and March 2003, patients with non-metastatic colon cancer were recruited by 29 hospitals in eight countries and randomised to either laparoscopic or open surgery. Main inclusion criterion for the COLOR trial was solitary adenocarcinoma of the left or right colon. The primary outcome was disease-free survival at 3 years, and secondary outcomes included overall survival and recurrence. The 10-year follow-up data of all Dutch patients were collected. Analysis was by intention-to-treat. The trial was registered at ClinicalTrials.gov (NCT00387842). In total, 1248 patients were randomised, of which 329 were Dutch. Fifty-eight Dutch patients were excluded and 15 were lost to follow-up, leaving 256 patients for 10-year analysis. Median follow-up was 112 months. Disease-free survival rates were 45.2 % in the laparoscopic group and 43.2 % in the open group (difference 2.0 %; 95 % confidence interval (CI) -10.3 to 14.3; p = 0.96). Overall survival rates were 48.4 and 46.7 %, respectively (difference 1.7 %; 95 % CI -10.6 to 14.0; p = 0.83). Stage-specific analysis revealed similar survival rates for both groups. Sixty-two patients were diagnosed with recurrent disease, accounting for 29.4 % in the laparoscopic group and 28.2 % in the open group (difference 1.2 %; 95 % CI -11.1 to 13.5; p = 0.73). Seven patients had port- or wound-site recurrences (laparoscopic n = 3 vs. open n = 4). Laparoscopic surgery for non-metastatic colon cancer is associated with similar rates of disease-free survival, overall survival and recurrences as open surgery at 10-year follow-up.

The importance of the glycerol 3-phosphate shuttle during aerobic growth of Saccharomyces cerevisiae.

- Maintenance of a cytoplasmic redox balance is a necessity for sustained cellular metabolism. Glycerol formation is the only way by which Saccharomyces cerevisiae can maintain this balance under anaerobic conditions. Aerobically, on the other hand, several different redox adjustment mechanisms exist, one of these being the glycerol 3-phosphate (G3P) shuttle. We have studied the importance of this shuttle under aerobic conditions by comparing growth properties and glycerol formation of a wild-type strain with that of gut2 delta mutants, lacking the FAD-dependent glycerol 3-phosphate dehydrogenase, assuming that the consequent blocking of G3P oxidation is forcing the cells to produce glycerol from G3P. To impose different demands on the redox adjustment capability we used various carbon sources having different degrees of reduction. The results showed that the shuttle was used extensively with reduced substrate such as ethanol, whereas the more oxidized substrates lactate and pyruvate, did not provoke any activity of the shuttle. However, the absence of a functional G3P shuttle did not affect the growth rate or growth yield of the cells, not even during growth on ethanol. Presumably, there must be alternative systems for maintaining a cytoplasmic redox balance, e.g. the so-called external NADH dehydrogenase, located on the outer side of the inner mitochondrial membrane. By comparing the performance of the external NADH dehydrogenase and the G3P shuttle in isolated mitochondria, it was found that the former resulted in high respiratory rates but a comparably low P/O ratio of 1.2, whereas the shuttle gave low rates but a high P/O ratio of 1.7. Our results also demonstrated that of the two isoforms of NAD-dependent glycerol 3-phosphate dehydrogenase, only the enzyme encoded by GPD1 appeared important for the shuttle, since the enhanced glycerol production that occurs in a gut2 delta strain proved dependent on GPD1 but not on GPD2.

Cancer-associated fibroblast-secreted CXCL16 attracts monocytes to promote stroma activation in triple-negative breast cancers

Tidskriftsartikel (refereegranskat)abstract
- Triple-negative (TN) breast cancers (ER â ' PR â ' HER2 â ') are highly metastatic and associated with poor prognosis. Within this subtype, invasive, stroma-rich tumours with infiltration of inflammatory cells are even more aggressive. The effect of myeloid cells on reactive stroma formation in TN breast cancer is largely unknown. Here, we show that primary human monocytes have a survival advantage, proliferate in vivo and develop into immunosuppressive myeloid cells expressing the myeloid-derived suppressor cell marker S100A9 only in a TN breast cancer environment. This results in activation of cancer-associated fibroblasts and expression of CXCL16, which we show to be a monocyte chemoattractant. We propose that this migratory feedback loop amplifies the formation of a reactive stroma, contributing to the aggressive phenotype of TN breast tumours. These insights could help select more suitable therapies targeting the stromal component of these tumours, and could aid prediction of drug resistance.

- An inappropriate host response to invading bacteria is a critical parameter that often aggravates the outcome of an infection. Staphylococcus aureus is a major human Gram-positive pathogen that causes a wide array of community- and hospital-acquired diseases ranging from superficial skin infections to severe conditions such as staphylococcal toxic shock. Here we find that S aureus induces inflammatory reactions by modulating the expression and response of the B1 and B2 receptors, respectively. This process is initiated by a chain of events, involving staphylococcal-induced cytokine release from monocytes, bacteria-triggered contact activation, and conversion of bradykinin to its metabolite desArg9bradykinin. The data of the present study implicate an important and previously unknown role for kinin receptor regulation in S aureus infections.

- AIMS: To analyse time-trends in survival of patients with colon and rectal cancer in Sweden.PATIENTS AND METHODS: Data including all patients diagnosed with adenocarcinoma of the colon and rectum between 1960 and 1999, from the Swedish Cancer Registry, were analysed. The observed and relative survival rates were calculated according to the Hakulinen cohort method.RESULTS: Five-year relative survival rate for cancer of the colon improved significantly from 39.6% in 1960--1964 to 57.2% in 1995--1999 and for rectal cancer from 36.1 to 57.6%, respectively. Corresponding observed survival improved from 31.2 to 44.3% for colon cancer and from 28.4 to 45.4% for rectal cancer. The largest improvement of survival were seen during the later part of the period observed.CONCLUSION: The survival of patients with colon and rectal cancer in Sweden continues to improve, especially in rectal cancer, which now has a 5-year observed and relative survival rate comparable to that for colon cancer. The survival improvement in rectal cancer is probably a result of the implementation of total mesorectal excision and pre-operative radiotherapy.

Tidskriftsartikel (refereegranskat)abstract
- BACKGROUND: The aim of the study was to analyse late gastrointestinal disorders necessitating hospital admission following rectal cancer surgery and to determine their relationship to preoperative radiation therapy. METHODS: Curatively treated patients participating in the Swedish Rectal Cancer Trial during 1987-1990, randomized to preoperative irradiation (454 patients) or surgery alone (454), were matched against the Swedish Hospital Discharge Registry. Hospital records for patients admitted with gastrointestinal diagnoses were reviewed. RESULTS: Irradiated patients had an increased relative risk (RR) of late small bowel obstruction (RR 2.49 (95 per cent confidence interval (c.i.) 1.48 to 4.19)) and abdominal pain (RR 2.09 (95 per cent c.i. 1.03 to 4.24)) compared with patients treated by surgery alone. The risk of late small bowel obstruction requiring surgery was greatly increased (RR 7.42 (95 per cent c.i. 2.23 to 24.66)). Irradiated patients with postoperative anastomotic leakage were at increased risk for late small bowel obstruction (RR 2.99 (95 per cent c.i. 1.07 to 8.31)). The risk of small bowel obstruction was also related to the radiation technique and energy used. CONCLUSION: Small bowel obstruction is more common in patients with rectal cancer treated with preoperative radiation therapy.

Respiratory adenovirus infections in immunocompetent and immunocompromised adult patients
- 2020

Tidskriftsartikel (refereegranskat)abstract
- Adenovirus (AdV) can cause severe respiratory infections in children and immunocompromised patients, but less is known about severe AdV pneumonia in immunocompetent adults. In this retrospective study, we compared respiratory tract infections and pneumonia caused by AdV in immunocompromised and immunocompetent adult patients regarding clinical presentation and severity of infection. The results show that AdV can cause severe infections in both immunocompetent and immunocompromised patients, and the clinical presentation and need for hospitalisation, mechanical ventilation and antiviral treatment were equal in both groups. No underlying risk factors for severe AdV infection in healthy individuals were identified.

Tidskriftsartikel (refereegranskat)abstract
- Aim To compare the prevalence of gastrostomy tube feeding (GTF) of children with cerebral palsy (CP) in six European countries. Method Data on 1295 children (754 males, 541 females; mean age 5y 11mo, range 11y 2mo, min 6mo, max 11y 8mo) with CP born from 1999 to 2001 were collected from geographically defined areas in six European countries; four of the areas covered the whole country. Distribution of CP was unilateral 37%, bilateral 51%, dyskinetic 8%, and ataxic 4%. Sixty children were classified in Gross Motor Function Classification System (GMFCS) levels I and II, 6 in level III and 34 in levels IV and Vas Outcome measures were GTF, age at placement, feeding difficulties and the children's height and weight for age standard deviation scores (z-scores). Results The use of GTF among all children with CP was highest in western Sweden (22%, 95% confidence interval [CI] 16-29), and lowest in Portugal (6%, 95% CI 3-10), northern England (6%, 95% CI 3-9) and in Iceland (3%, 95% CI 0-13; p<0.001). The difference between areas was greater among children in GMFCS levels IV and V (non-ambulant); in this group, lower height z-scores were more prevalent in the areas with lower prevalence of GTF. The children's age at placement of gastrostomy also varied between areas (p<0.002). Interpretation The observed differences in the use of GTF may reflect differences in access to treatment or clinical practice, or both. Our results suggest that the use of GTF may improve growth in height and weight among children with more severely affected gross motor function - the group most likely to have associated feeding difficulties.

Tidskriftsartikel (refereegranskat)abstract
- Background: Neuroblastoma tumor cells are assumed to originate from primitive neuroblasts giving rise to the sympathetic nervous system. Because these precursor cells are not detectable in postnatal life, their transcription profile has remained inaccessible for comparative data mining strategies in neuroblastoma. This study provides the first genome-wide mRNA expression profile of these human fetal sympathetic neuroblasts. To this purpose, small islets of normal neuroblasts were isolated by laser microdissection from human fetal adrenal glands. Results: Expression of catecholamine metabolism genes, and neuronal and neuroendocrine markers in the neuroblasts indicated that the proper cells were microdissected. The similarities in expression profile between normal neuroblasts and malignant neuroblastomas provided strong evidence for the neuroblast origin hypothesis of neuroblastoma. Next, supervised feature selection was used to identify the genes that are differentially expressed in normal neuroblasts versus neuroblastoma tumors. This approach efficiently sifted out genes previously reported in neuroblastoma expression profiling studies; most importantly, it also highlighted a series of genes and pathways previously not mentioned in neuroblastoma biology but that were assumed to be involved in neuroblastoma pathogenesis. Conclusion: This unique dataset adds power to ongoing and future gene expression studies in neuroblastoma and will facilitate the identification of molecular targets for novel therapies. In addition, this neuroblast transcriptome resource could prove useful for the further study of human sympathoadrenal biogenesis.

Tidskriftsartikel (refereegranskat)abstract
- BACKGROUND: The association between diverting stomas and symptomatic anastomotic leakage after rectal cancer surgery was studied, as well as the impact of leakage on local recurrence, distant metastasis, and disease-free, overall and cancer-specific survival. METHODS: Data from the Swedish Rectal Cancer Trial, Dutch TME trial, CAO/ARO/AIO-94 trial, EORTC 22921 trial and Polish Rectal Cancer Trial were pooled (n = 5187). All eligible patients without distant metastases at the time of low anterior resection were selected (n = 2726); overall survival was studied in patients aged 75 years or less (n = 2480). Multivariable models were used to study the association between diverting stomas and anastomotic leakage, and between leakage and recurrence or survival. RESULTS: Some 9.7 per cent of patients were diagnosed with a symptomatic anastomotic leak; diverting stomas were negatively associated with leakage (11.6 per cent without and 7.8 per cent with a stoma; P = 0.002). Anastomotic leakage was negatively associated with overall survival in the multivariable analysis (hazard ratio (HR) 1.29 (95 per cent confidence interval 1.02 to 1.63); P = 0.034), but not with cancer-specific survival (HR 1.12 (0.83 to 1.52); P = 0.466). CONCLUSION: Diverting stomas were associated with less symptomatic anastomotic leakage. Oncological outcome was not significantly influenced by leakage, but overall survival was reduced.

Comparative immunohistochemical demonstration of difucosylated carbohydrate antigens and CEA in adenomas and carcinomas of the rectum and rectosigmoid
- 1986
-
Ingår i: Anticancer research. - 1791-7530. ; 6:2, s. 139-146
-
Tidskriftsartikel (refereegranskat)abstract
- The present immunohistochemical investigation reveals that difucosylated carbohydrate antigens (DFCA) are extensively expressed in rectal and rectosigmoid carcinomas while normal mucosa and hyperplastic polyps are mainly negative. The adenomas showed intermediate staining patterns where adenomas with villous structures and moderate-severe dysplasia resembled of carcinomas. CEA was more extensively expressed in both normal, premalignant, and malignant tissue. Thus, DFCA is better than CEA as a discriminator between normal and malignant tissue in the distal large bowel, and may be used in future studies with the intention of advancing our understanding of the neoplastic process and assessing clinical relevance.

- AIM: To investigate the relation between the type of circular stapler and anastomotic leak in rectal cancer surgery.BACKGROUND: During the past decades results from rectal cancer surgery have improved considerably regarding risk of local recurrence and survival. Two main paradigm changes are considered to be the cause for this: the introduction of total mesorectal excision (TME) and the increasing use of radiotherapy. However, rectal cancer surgery is associated with an unacceptably high frequency of complications of which anastomotic leak is one of the most severe ones. The hypothesis was raised that the choice of stapler influenced the leakage rates.METHODS: A questionnaire was sent to all departments of surgery (n = 66) performing rectal cancer surgery in Sweden to determine the choice of circular stapler when performing anterior resection for rectal cancer. These data were linked to the Swedish Rectal Cancer Registry for the period 1995-99.RESULTS: A total of 3316 patients had an anterior resection. The choice of circular stapling device was determined in 70% of the cases. When stapler A was used, the leakage rate was 11% whereas it was 7% when stapler B was used (P = 0.0039). In the cases where it was impossible to determine which stapler had been used the leakage rate was 8%.CONCLUSION: Quality control is an important part of medicine and the present study suggests that it also must include surgical instruments. A prospective randomised study is needed to confirm the results.

- Cell ingrowth, hydroxyproline accumulation, and mRNA expression of collagen I were measured in two polytetrafluoroethylene grafts implanted subcutaneously at the time of colorectal cancer surgery to evaluate the influence of early postoperative chemotherapy on human wound healing. Eleven patients treated with intraperitoneal 5-fluorouracil and intravenous folinic acid Days 1-6 after operation were compared with 15 patients who underwent surgery alone. At 1 week, chemotherapy-treated patients had accumulated less hydroxyproline (mean 0.35 +/- 0.33 micrograms/cm) compared with untreated patients (mean 0.73 +/- 0.37 micrograms/cm, P < 0.05). By 2 weeks, the hydroxyproline content had increased sixfold in the chemotherapy group (P < 0.01) and threefold in the nonchemotherapy group (P < 0.01) and there was no difference between the groups. Cell and connective tissue ingrowth and total RNA content did not differ between the groups at any point in time, but at 1 week the mRNA expression of collagen I was higher in the chemotherapy group (P < 0.05). These results indicate that collagen accumulation in human subjects is reduced during a short course of postoperative chemotherapy and normalizes after the end of treatment.

- OBJECTIVE: A diverting loop ileostomy was previously considered mandatory for minimizing the effects of septic complications in pelvic pouch surgery. During the past decade there has been a trend towards omission of the loop ileostomy without obvious signs of increased numbers of pouch complications or impaired long-term function. The aim of the present study was to evaluate the risk of complications associated with the construction and closure of the loop ileostomy itself.PATIENTS AND METHODS: Complications following diverting loop ileostomies in 143 patients subjected to restorative pelvic pouch surgery during the period 1983-97 were studied retrospectively by evaluation of case records.RESULTS: In the period between discharge after pelvic pouch surgery and closure of the loop ileostomy, 20 (14%) patients were hospitalized because of excessive stoma flow and 19 (13%) patients were treated for other surgical complications, of whom 10 (7%) required surgical intervention. In the early postoperative period (within 30 days) after closure of the loop ileostomy, 18 (13%) patients suffered complications necessitating surgery. Another 12 (8%) patients were hospitalized because of intestinal obstruction that could be treated conservatively.CONCLUSION: The proportion of complications associated with diverting loop ileostomies in pelvic pouch surgery was considerable. A randomised controlled multicentre study is ethically defensible and is recommended.

- BACKGROUND: Population-based quality registers have become an important tool in quality assessment during the past decade. For registers to be reliable, however, data must be checked carefully for validity.METHODS: The present study describes the validity of surgical complications registered in a national register run by the National Board of Health and Welfare (NBH), a register run by Regional Oncological Centres (ROC) and, for comparison, a local quality assurance system at Uppsala University Hospital (UUH). A specialized, independent surgeon checked 10 per cent of patient records against datasheets from the registers.RESULTS: The local quality assurance system at UUH showed the best validity for surgical complications. Data for complications of colonic cancer surgery were more valid than those for rectal cancer surgery. Registration of serious complications was more valid than that of wound infections. The calculated proportion of missed surgical complications was 0.69, 0.64, 0.40, 0.22 and 0.07 for rectal and colonic cancer in the NBH register, rectal and colonic cancer in the ROC register, and the UUH register respectively. Corresponding figures for reoperation were 0.45, 0.48, 0.04, 0.09 and 0.21.CONCLUSION: Local interest and routine use of data for quality assurance are crucial factors for valid registers. Careful monitoring of validity is necessary for use of registry data in structured systems for improvement of surgical results.

- The aim is to study access to intrathecal baclofen (ITB) for children with cerebral palsy (CP) in Europe, as an indicator of access to advanced care.Surveys were sent to CP registers, clinical networks, and pump manufacturers. Enquiries were made about ITB treatment in children born in 1990 to 2005 by sex, CP type, level of gross motor function classification system (GMFCS) and age at the start of treatment. Access to ITB was related to the country's gross domestic product (GDP) and % GDP spent on health.In 2011 population-based data from Sweden, Norway, England, Portugal, Slovenia, and Denmark showed that 114 (3.4%) of 3,398 children with CP were treated with ITB, varying from 0.4 to 4.7% between centers. The majority of the children were at GMFCS levels IV-V and had bilateral spastic CP. In Sweden, dyskinetic CP was the most commonly treated subtype. Boys were more often treated with ITB than girls (p=0.014). ITB was reported to be available for children with CP in 25 of 43 countries. Access to ITB was associated with a higher GDP and %GDP spent on health (p<0.01). Updated information from 2019 showed remaining differences between countries in ITB treatment and sex difference in treated children was maintained.There is a significant difference in access to ITB for children with CP across Europe. More boys than girls are treated. Access to ITB for children with CP is associated with GDP and percent of GDP spent on health in the country.

Tidskriftsartikel (refereegranskat)abstract
- Chills and vomiting have traditionally been associated with severe bacterial infections and bacteremia. However, few modern studies have in a prospective way evaluated the association of these signs with bacteremia, which is the aim of this prospective, multicenter study. Patients presenting to the emergency department with at least one affected vital sign (increased respiratory rate, increased heart rate, altered mental status, decreased blood pressure or decreased oxygen saturation) were included. A total of 479 patients were prospectively enrolled. Blood cultures were obtained from 197 patients. Of the 32 patients with a positive blood culture 11 patients (34%) had experienced shaking chills compared with 23 (14%) of the 165 patients with a negative blood culture, p=0.009. A logistic regression was fitted to show the estimated odds ratio (OR) for a positive blood culture according to shaking chills. In a univariate model shaking chills had an OR of 3.23 (95% CI 1.35-7.52) and in a multivariate model the OR was 5.9 (95% CI 2.05-17.17) for those without prior antibiotics adjusted for age, sex and prior antibiotics. The presence of vomiting was also addressed, but neither a univariate nor a multivariate logistic regression showed any association between vomiting and bacteremia. In conclusion, among patients at the emergency department with at least one affected vital sign, shaking chills but not vomiting were associated with bacteremia.

- AIMS: The aim of this study was to describe variability in compliance to clinical guidelines in colorectal cancer surgery related to hospital structure.METHODS: All patients registered in the databases of the Regional Oncologic Centre, operated upon electively for colon cancer between the start of the register in 1997 until 2000 (n=1771) and for rectal cancer between the start of the register in 1995 until 2000 (n=1841) were selected for analysis.RESULTS: There was no difference in 5-year survival rate between colon and rectal cancer (mean follow-up 2.6 and 3.0 years, respectively; p=0.22). There was a significant difference in frequency of preoperative liver scan depending on hospital category with an increase in colon cancer from 39 to 46% (p=0.02) and in rectal cancer from 42 to 64% (p<0.001). For colon cancer there was no difference, according to hospital category, in quotient sigmoid and high anterior resection to left-sided resection. Furthermore, high anterior resection was more common at university and general district hospitals (8%) compared with district hospitals (4%) (p=0.01). Sphincter-saving surgery was more common at university hospitals and district general hospitals than at district hospitals (low anterior/abdomino-perineal resection quotients 2.3, 2.4 and 1.6, respectively; p<0.001).CONCLUSIONS: Population-based audit forms an appropriate and valuable basis for quality assurance projects. In addition to describing compliance to guidelines and pointing to process steps that can be improved, such investigations may also indicate changes due to scientific development. Linked to case-costing data, such results may form an important basis for decisions about modifications in health care.

- OBJECTIVE: To assess whether intraoperative lavage and primary resection with anastomosis is a safe alternative to a Hartmann procedure in emergency surgery of the left colon.DESIGN: Retrospective study.SETTING: University hospital.MATERIAL: 101 consecutive patients (39 emergency and 62 elective) who underwent a left-sided colonic resection during a 3-year-period.INTERVENTIONS: 17 of the emergency procedures comprised an intraoperative lavage followed by resection and primary anastomosis without faecal diversion; 17 were Hartmann procedures and 5 patients had primary resection without lavage.MAIN OUTCOME MEASURES: Postoperative mortality, morbidity and duration of hospital stay in these two groups compared with these after a contemporary series of elective resections.RESULTS: There were no postoperative deaths and no clinical anastomotic leaks in the lavage group. The duration of hospital stay (median 11 days) was similar in both groups (overall and sigmoid resection respectively). In the Hartmann group, there were two deaths and the postoperative stay in hospital was significantly longer.CONCLUSIONS: Primary resection with intraoperative lavage can be done successfully in patients with acute obstruction of the left colon and the duration of hospital stay and morbidity are similar to those seen in patients operated on electively.

- The expression and distribution of integrin subunits alpha 2 and alpha 3 and two of their putative ligands, type IV collagen and laminin, were examined by immunohistochemistry in specimens from 33 consecutive patients operated on for colorectal adenocarcinomas. Both tumour cells and normal epithelium expressed the alpha 2 and alpha 3 subunits. Two typical patterns of expression could be discerned; a basolateral expression and a diffuse cytoplasmic expression. The stained tumour specimens were assessed according to (i) distribution of integrin expression (diffusely cytoplasmic or basolateral), (ii) continuity in basolateral integrin expression, and (iii) interconnection of integrin expression and expression of type IV collagen and laminin. These parameters were then related to tumour differentiation, tumour stage according to Dukes' classification, DNA-ploidy and patient survival (median observation time was 30 months; range 24-35). The continuity in the basolateral expression of alpha 3 but not of alpha 2, correlated with the basal membrane expression of type IV collagen (P < 0.001). Loss of continuity in the basolateral expression of both integrins was significantly related to impaired tumour differentiation (alpha 2 P = 0.02; alpha 3 P = 0.01), more advanced Dukes' stage (alpha 2 = 0.07, alpha 3 P < 0.001), survival rate (both integrins P < 0.05), but not to DNA-ploidy. These data suggest that determination of the pattern of expression of the integrin subunits alpha 2 and alpha 3 in the preoperative biopsy and the surgical specimen could be used as a prognostic indicator.

- PURPOSE: Better prognostic predictors in colorectal cancer than the Dukes stage are necessary for individualized therapy and follow-up.METHODS: Survival among 212 patients operated on for colorectal cancer was examined regarding various clinical, histopathologic, cellular, and serologic tumor characteristics.RESULTS: Beside the Dukes stage, which was the most powerful variable, the erythrocyte sedimentation rate, leukocyte blood count, alkaline phosphatase, aspartate aminotransferase, six different serum tumor markers, number of small blood vessels, and age were found to be significantly associated with survival. The leukocyte blood count, alkaline phosphatase, and aspartate aminotransferase retained their significance in a multivariate model including tumor differentiation, local tumor stage, and age. Inclusion of tissue polypeptide antigen, the most powerful tumor marker in the multivariate model, showed that only the tumor stage, tissue polypeptide antigen, and age were statistically significantly correlated to survival. This was valid both for the group of patients considered as potentially curable and for those who potentially have been cured (Dukes Stages A-C).CONCLUSIONS: A great number of prognostic predictors failed to discard Dukes stage as the best one. One serum tumor marker, tissue polypeptide antigen, contains independent additional prognostic information.

- BACKGROUND: The importance of growth factors, such as platelet-derived growth factor (PDGF), for stromal activation in colorectal cancer is unclear.EXPERIMENTAL DESIGN: The expression of beta-receptors for PDGF, and PDGF B-chain (PDGF AB and PDGF BB) was investigated by immunohistologic techniques in full-thickness biopsies from 210 colorectal cancers. These antigens were detected by the monoclonal antibodies PDGFR-B2 and PDGF 007, respectively.RESULTS: All tumors contained granular clusters of PDGF beta-receptor expressing stromal cells, whereas tumor epithelium was invariably negative. The staining was most prominent in vascular cells. There were several cells in the tumor stroma that expressed PDGF AB/BB. Double immunofluorescence stainings in specimens from four patients performed in order to characterize PDGF beta-receptor- and PDGF AB/BB expressing cells showed that cells expressing PDGF beta-receptors did not express PDGF AB/BB. About 20% of cells in the stroma expressing PDGF AB/BB were macrophages (CD68-positive cells), whereas the nature of the remaining stromal cells expressing PDGF AB/BB could not be disclosed. Furthermore, about 30% of CD68-positive macrophages expressed PDGF AB/BB, but not PDGF beta-receptors. The extent of clusters of PDGF beta-receptor expressing cells varied considerably between tumors, and its prognostic value was considered in the entire tumor material. The number of clusters did, however, not correlate to tumor differentiation, tumor stage according to Dukes', or outcome.CONCLUSIONS: The presence of cells expressing PDGF beta-receptor and PDGF AB/BB respectively, i.e., expression of the receptor and its ligand, fulfills two of the prerequisites for a role of PDGF in the activation of stromal cells in colorectal cancers. The data suggest that stromal activation, characterized by clusters of PDGF beta-receptor expressing cells, is of importance for the formation of tumor stroma per se. However, the expression of the PDGF beta-receptor has no potential as a prognostic marker.

- ID ( inhibitor of differentiation/DNA binding) proteins, frequently deregulated in advanced human malignancies, can participate in multiple fundamental traits of cancer, such as block of differentiation, increased proliferation, tissue invasiveness, and angiogenesis. We have previously demonstrated that hypoxia decreases expression of neuronal marker genes in neuroblastoma, but induces genes expressed in the neural crest, such as ID2. Because of its involvement in normal neural crest development and its ability to inhibit proneuronal bHLH proteins, the hypoxic induction of ID2 was of particular interest. Here we report fast induction kinetics of ID2 expression in hypoxic neuroblastoma cells. The up-regulation of ID2 was abolished by addition of actinomycin D, implicating a hypoxia-driven transcriptional mechanism. Analyzing the ID2 promoter revealed several potential binding sites for hypoxia-inducible factors. Subsequent electrophoretic mobility shift and chromatin immunoprecipitation assays demonstrated two functional HIF-1 binding sites within ID2 gene regulatory sequences located at -725 and -1893 relative to the transcriptional initiation point. In transfection assays, DNA constructs of the ID2 promoter, including the functional HIF-1 binding sites, induced luciferase reporter activity in a HIF-1-specific manner. These observations demonstrate that ID2 is actively engaged by hypoxia and represents a novel HIF-1 target. Hypoxia-induced ID2 expression could play a significant role in the previously observed dedifferentiation of hypoxic neuroblastoma cells, which in a clinical setting could lead to less mature and more aggressive tumors.

- BackgroundLarge international differences in colorectal cancer survival exist, even between countries with similar healthcare. We investigate the extent to which stage at diagnosis explains these differences.MethodsData from population-based cancer registries in Australia, Canada, Denmark, Norway, Sweden and the UK were analysed for 313 852 patients diagnosed with colon or rectal cancer during 2000-2007. We compared the distributions of stage at diagnosis. We estimated both stage-specific net survival and the excess hazard of death up to three years after diagnosis, using flexible parametric models on the log-cumulative excess hazard scale.ResultsInternational differences in colon and rectal cancer stage distributions were wide: Denmark showed a distribution skewed towards later-stage disease, while Australia, Norway and the UK showed high proportions of 'regional' disease. One-year colon cancer survival was 67% in the UK and ranged between 71% (Denmark) and 80% (Australia and Sweden) elsewhere. For rectal cancer, one-year survival was also low in the UK (75%), compared to 79% in Denmark and 82-84% elsewhere. International survival differences were also evident for each stage of disease, with the UK showing consistently lowest survival at one and three years.ConclusionDifferences in stage at diagnosis partly explain international differences in colorectal cancer survival, with a more adverse stage distribution contributing to comparatively low survival in Denmark. Differences in stage distribution could arise because of differences in diagnostic delay and awareness of symptoms, or in the thoroughness of staging procedures. Nevertheless, survival differences also exist for each stage of disease, suggesting unequal access to optimal treatment, particularly in the UK.

- BACKGROUND: Decision making regarding the choice of surgical procedure in rectal cancer is complex. It was hypothesized that, in addition to clinical factors, several aspects of patients' socioeconomic background influence this process. METHODS: Individually attained data on civil status, education and income were linked to the Swedish Rectal Cancer Registry 1995-2005 (16 713 patients) and analysed by logistic regression. RESULTS: Anterior resection (AR) was performed in 7433 patients (44.5 per cent), abdominoperineal resection (APR) in 3808 (22.8 per cent) and Hartmann's procedure in 1704 (10.2 per cent). Unmarried patients were least likely (odds ratio (OR) 0.76, 95 per cent confidence interval (c.i.) 0.64 to 0.88) and university-educated men were most likely (OR 1.30, 1.04 to 1.62) to have an AR. Patients with the highest income were more likely to undergo AR (OR 0.80, 0.85 and 0.86 respectively for first, second and third income quartiles). Socioeconomic differences in the use of AR were smallest among the youngest patients. Unmarried patients were more likely (OR 1.21, 95 per cent c.i. 1.00 to 1.48) and university-educated patients less likely (OR 0.78, 95 per cent c.i. 0.63 to 0.98) to have an APR. CONCLUSION: The choice of surgical strategy in rectal cancer is not socioeconomically neutral. Confounding factors, such as co-morbidity or smoking, may explain some of the differences but inequality in treatment is also plausible.
