    • BACKGROUND. Colorectal cancer is one of the most common forms of cancer in the Western world. Staging based on histopathology is currently the most accurate predictor of outcome after surgery. Colorectal cancer is curable if treated at an early stage (stage I-III). However, for tumors in stages II and III there is a great need for tests giving more accurate prognostic information defining the patient population in need of closer follow-up and/or adjuvant therapy. Furthermore, tests that provide prognostic information preoperatively could provide a guide both for preoperative oncologic treatment and the surgical procedure. METHODS. Peripheral blood mononuclear cells (PBMCs) were isolated preoperatively, within a week before primary surgery, from 39 patients undergoing surgery for colorectal cancer. The PBMCs were cultured in vitro for 24 hours in the presence of autologous serum and lipopolysaccharide (LPS). Interleukin-6 (IL-6) production was measured with enzyme-linked immunosorbent assay (ELISA). Staging based on histopathology was performed in all patients. Patients were followed for at least 54 months. RESULTS. A production of >5000 pg/mL of IL-6 identified colorectal cancer patients with a poor prognosis. Eight out of 13 patients with >5000 pg/mL IL-6 died from cancer within the follow-up period, whereas no cancer-related deaths were recorded among 21 patients with 5000 pg/mL IL-6 or less. A multivariate Cox regression analysis, stratified for T- and N-stage, identified IL-6 production as an independent prognostic factor. CONCLUSIONS. IL-6 production in vitro by PBMC can predict survival after radical surgery for colorectal cancer. © 2007 American Cancer Society.

  • Long term results of a randomized study by the Swedish Melanoma Study Group on 2-cm versus 5-cm resection margins for patients with cutaneous melanoma with a tumor thickness of 0.8-2.0 mm
  • 2000
  • Ingår i: Cancer. - 0008-543X .- 1097-0142. ; 89:7, s. 1495-1501
  • Tidskriftsartikel (refereegranskat)abstract
    • BACKGROUND. Large, prospective, randomized trials with long term follow-up are required to obtain an unbiased evaluation of the significance of resection margins in patients with cutaneous melanoma. METHODS, The Swedish Melanoma Study Group performed a prospective, randomized, multicenter study of patients with primary melanoma located on trunk or extremities and with a tumor thickness > 0.8 mm and less than or equal to 2 mm. Patients were allocated randomly to a 2-cm excision margin or a 5-cm excision margin. In total, 989 patients were recruited during the period 1982-1991. The median follow-up, was 11 years (range, 7-17 years) for estimation of survival and 8 years (range, 0-17 years) for evaluation of recurrent disease. RESULTS. The crude rate of local recurrence, defined as a recurrence in the scar or transplant, was < 1% (8 of 989 patients). Twenty percent of the patients (194 of 989 patients) experienced any disease recurrence, and 15% (146 of 989 patients) died of melanoma. There were no statistically significant differences between the two treatment arms. In a multivariate Cox analysis with patients allocated to wide excision as the reference group, the estimated relative hazards for overall survival and recurrence free survival among those allocated to a 2-cm resection margin were 0.96 (95% confidence interval, 0.75-1.24), and 1.02 (95% confidence interval, 0.80-1.30), respectively. CONCLUSIONS. In this long term follow-up study, local recurrences were found to be rare among patients with tumors > 0.8 mm thick and less than or equal to 2.0 mm thick. Mo difference in recurrence rate or survival between the two treatment groups was found. Patients in this category can be treated with a resection margin of 2 cm as safely as with a resection margin of 5 cm. Cancer 2000,89:1495-501. (C) 2000 American Cancer Society.

  • Perinatal and Familial Risk Factors for Acute Lymphoblastic Leukemia in a Swedish National Cohort
  • 2015
  • Ingår i: Cancer. - : Wiley. - 1097-0142 .- 0008-543X. ; 121:7, s. 1040-1047
  • Tidskriftsartikel (refereegranskat)abstract
    • BACKGROUNDPerinatal factors including high birth weight have been found to be associated with acute lymphoblastic leukemia (ALL) in case-control studies. However, to the best of our knowledge, these findings have seldom been examined in large population-based cohort studies, and the specific contributions of gestational age and fetal growth remain unknown. METHODSThe authors conducted a national cohort study of 3,569,333 individuals without Down syndrome who were born in Sweden between 1973 and 2008 and followed for the incidence of ALL through 2010 (maximum age, 38 years) to examine perinatal and familial risk factors. RESULTSThere were 1960 ALL cases with 69.7 million person-years of follow-up. After adjusting for potential confounders, risk factors for ALL included high fetal growth (incidence rate ratio [IRR] per additional 1 standard deviation, 1.07; 95% confidence interval [95% CI], 1.02-1.11 [P =.002]; and IRR for large vs appropriate for gestational age, 1.22; 95% CI, 1.06-1.40 [P =.005]), first-degree family history of ALL (IRR, 7.41; 95% CI, 4.60-11.95 [P<.001]), male sex (IRR, 1.20; 95% CI, 1.10-1.31 [P<.001]), and parental country of birth (IRR for both parents born in Sweden vs other countries, 1.13; 95% CI, 1.00-1.27 [P =.045]). These risk factors did not appear to vary by patient age at the time of diagnosis of ALL. Gestational age at birth, season of birth, birth order, multiple birth, parental age, and parental education level were not found to be associated with ALL. CONCLUSIONSIn this large cohort study, high fetal growth was found to be associated with an increased risk of ALL in childhood through young adulthood, independent of gestational age at birth, suggesting that growth factor pathways may play an important long-term role in the etiology of ALL. Cancer 2015;121:1040-1047. (c) 2014 American Cancer Society. The authors conducted what, to their knowledge, is the largest population-based cohort study to date to examine perinatal and familial risk factors for acute lymphoblastic leukemia (ALL) among approximately 3.5 million individuals born in Sweden between 1973 and 2008. High fetal growth was found to be associated with an increased risk of ALL in childhood through young adulthood, independent of gestational age at birth, suggesting that growth factor pathways may play an important long-term role in the etiology of ALL.

  • A Study of Body Image in Long-Term Breast Cancer Survivors
  • 2010
  • Ingår i: Cancer. - : Wiley. - 0008-543X .- 1097-0142. ; 116:15, s. 3549-3557
  • Tidskriftsartikel (refereegranskat)abstract
    • BACKGROUND: In this controlled postdiagnosis study, the authors examined various aspects of body image of breast cancer survivors in cross-sectional and longitudinal designs. METHODS: In 2004 and 2007 the Body Image Scale (BIS) was completed by the same 248 disease-free women who had been treated for stage II and III breast cancer between 1998 and 2002. "Poorer" body image was defined as greater than the 70th percentile (N = 76 women) of the BIS scores in contrast to "better" body image (N = 172 women). Breast cancer survivors were examined clinically in 2004, and their BIS scores were compared with the scores from an age-matched group of women from the general population. RESULTS: In this cross-sectional study, poorer body image in 2004 was associated significantly with modified radical mastectomy, undergoing or planning to undergo breast-reconstructive surgery, a change in clothing, poor physical and mental health, chronic fatigue, and reduced quality of life (QoL). In univariate analyses, most of these factors and manually planned radiotherapy were significant predictors of poorer body image in 2007. In multivariate analyses, manually planned radiotherapy, poor physical QoL and high BIS score in 2004 remained independent predictors of a poorer body image in 2007. Body image ratings were relatively stable from 2004 to 2007. Twenty-one percent of breast cancer survivors reported body image dissatisfaction, similar to the proportion of dissatisfaction in controls. CONCLUSIONS: In this cross-sectional analysis, body image in breast cancer survivors was associated with the types of surgery and radiotherapy and with mental distress, reduced health, and impaired QoL. Body image ratings were relatively stable over time, and the antecedent body image score was a strong predictor of body image at follow-up. Body image in breast cancer survivors differed very little from that in controls.

  • Active surveillance for early-stage prostate cancer : review of the current literature
  • 2008
  • Ingår i: Cancer. - : Wiley. - 0008-543X .- 1097-0142. ; 112:8, s. 1650-9
  • Tidskriftsartikel (refereegranskat)abstract
    • The natural history of prostate cancer is remarkably heterogeneous and, at this time, not completely understood. The widespread adoption and application of prostate-specific antigen (PSA) screening has led to a dramatic shift toward the diagnosis of low-volume, nonpalpable, early-stage tumors. Autopsy and early observational studies have shown that approximately 1 in 3 men aged >50 years has histologic evidence of prostate cancer, with a significant portion of tumors being small and possibly clinically insignificant. Utilizing the power of improved contemporary risk stratification schema to better identify patients with a low risk of cancer progression, several centers are gaining considerable experience with active surveillance and delayed, selective, and curative therapy. A literature review was performed to evaluate the rationale behind active surveillance for prostate cancer and to describe the early experiences from surveillance protocols. It appears that a limited number of men on active surveillance have required treatment, with the majority of such men having good outcomes after delayed selective intervention for progressive disease. The best candidates for active surveillance are being defined, as are predictors of active treatment. The psychosocial ramifications of surveillance for prostate cancer can be profound and future needs and unmet goals will be discussed.

  • Does FLT3 Mutation Impact Survival After Hematopoietic Stem Cell Transplantation for Acute Myeloid Leukemia? : A Center for International Blood and Marrow Transplant Research (CIBMTR) Analysis
  • 2016
  • Ingår i: Cancer. - : Wiley. - 0008-543X .- 1097-0142. ; 122:19, s. 3005-3014
  • Tidskriftsartikel (refereegranskat)abstract
    • BACKGROUND: Patients with FMS like tyrosine kinase 3 (FLT3)-mutated acute myeloid leukemia (AML) have a poor prognosis and are referred for early allogeneic hematopoietic stem cell transplantation (HCT). METHODS: Data from the Center for International Blood and Marrow Transplant Research (CIBMTR) were used to evaluate 511 adult patients with de novo AML who underwent HCT during 2008 through 2011 to determine whether FLT3 mutations had an impact on HCT outcomes. RESULTS: In total, 158 patients (31%) had FLT3 mutations. Univariate and multivariate analyses revealed an increased risk of relapse at 3 years in the FLT3 mutated group compared with the wild-type (WT) group (38% [95% confidence interval (CI), 30%-45%] vs 28% [95% CI, 24%-33%]; P = .04; relative risk, 1.60 [95% CI, 1.15-2.22]; P = .0048). However, FLT3 mutation status was not significantly associated with nonrelapse mortality, leukemia-free survival, or overall survival. Although more patients in the FLT3 mutated group died from relapsed primary disease compared with those in the WT group (60% vs 46%), the 3-year overall survival rate was comparable for the 2 groups (mutated group: 49%; 95% CI, 40%-57%; WT group: 55%, 95% CI, 50%-60%; P = .20). CONCLUSIONS: The current data indicate that FLT3 mutation status did not adversely impact overall survival after HCT, and about 50% of patients with this mutation who underwent HCT were long-term survivors.

  • Core-needle biopsy performed by the cytopathologist : a technique to complement fine-needle aspiration of soft tissue and bone lesions
  • 2005
  • Ingår i: Cancer. - : Wiley. - 1097-0142 .- 0008-543X. ; 105:4, s. 229-239
  • Tidskriftsartikel (refereegranskat)abstract
    • BACKGROUND: Fine-needle aspiration cytology (FNAC) is gaining increased popularity in the diagnosis of musculoskeletal lesions; and, in many patients, a definitive diagnosis can be rendered from aspiration smears alone. The main limitation of FNAC of soft tissue and bone neoplasms is in the evaluation of tissue architecture. In addition cytologic specimens are not always adequate for ancillary studies.METHODS: A consecutive series of 130 patients with soft tissue and bone lesions was examined by core-needle biopsy (CNB) performed by a cytopathologist in conjunction with FNAC. The findings of this combined diagnostic approach were compared with histologic diagnoses made on surgical biopsies and resected specimens from 86 patients. Adequate follow-up was available in all patients.RESULTS: FNAC combined with CNB correctly could identify 77 of 78 malignant lesions and 50 of 52 benign lesions. Only seven patients underwent incisional biopsy. The tumor subtype was determined correctly in 30 of 39 patients (77%) and the malignancy grade was determined in 35 of 39 patients (90%) with primary soft tissue and bone sarcomas compared with the biopsy or operative specimens.CONCLUSIONS: FNAC of musculoskeletal tumors/lesions complemented with CNB combined cytomorphology with tissue architecture and ancillary procedures. In the current study, obtaining FNAC as well as CNB at the same clinic visit and by the cytopathologist made preliminary diagnosis on the day of referral possible. This speeded diagnosis increased the number of correct diagnoses and usually enabled correct subtyping and malignancy grading of sarcomas.
