Higher number of steps and breaks during sedentary behaviour are associated with better lipid profiles.

BMC Public Health 2021 03 31;21(1):629. Epub 2021 Mar 31.

The UKK Institute for Health Promotion Research, Tampere, Finland.

Background: Physical activity (PA) is known to be associated with lipid profiles and the risk of both cardiovascular diseases and cancer. The aim of this study was to evaluate the association of objectively measured PA, sedentary behaviour (SB), amount of breaks during SB and number of daily steps with serum lipids in a healthy, Finnish, middle-aged, female population.

Methods: The participants (571) were recruited at mammography screening, target group was women aged 50-60 years. A measurement of PA was done with accelerometer, blood lipid profile was assessed, and questionnaires of participants characteristics were sent to participants.

Results: The participants with the highest number of daily breaks during SB (≥ 41) had the highest mean concentration of HDL-cholesterol (high density lipoprotein cholesterol, HDL-c) (1.9 mmol/l, standard deviation (SD) 0.4) and the lowest mean concentration of triglycerides (1.0 mmol/l, SD 0.5). HDL-c level was 0.16 mmol/l higher (p < 0.001) in the group with 28-40.9 breaks/day and 0.25 mmol/l higher (p < 0.001) among participants with ≥41 breaks/day than in the group with the fewest breaks during SB (< 28). Those with the most daily steps (≥ 9100) had the highest mean HDL-c level (1.9 mmol/l). HDL-c level was 0.16 mmol/l higher (p < 0.001) among the participants with 5600-9099 steps/day and 0.26 mmol/l higher (p < 0.001) among participants with ≥9100 steps/day than those with the fewest steps (< 5600). The number of daily steps was inversely associated with the triglyceride concentration. From wake-time, participants spent 60% in SB, 18% standing, 14% in light PA, and 9% in moderate-to-vigorous PA (MVPA). PA was associated with serum total cholesterol (TC), HDL-c and triglyceride levels. The mean HDL-c level was the highest in the lowest quartile of SB and in the highest quartile of MVPA.

Conclusions: To our knowledge, this is the first study showing a high number of objectively measured breaks during SB is associated with a favourable effect on the level of serum lipids, which may later translate into cardiovascular health among middle-aged women.

Trial Registration: This study was registered and approved by the Regional Ethics Committee of Tampere University Hospital in Finland (approval code R15137 ).

ECCO essential requirements for quality cancer care: Melanoma.

Crit Rev Oncol Hematol 2018 Feb 2;122:164-178. Epub 2018 Jan 2.

European CanCer Organisation (ECCO); Department of Surgery, Institute of Clinical Sciences, Sahlgrenska Academy, University of Gothenburg, Gothenburg, Sweden. Electronic address:

Background: ECCO essential requirements for quality cancer care (ERQCC) are explanations and descriptions of challenges, organisation and actions that are necessary to give high-quality care to patients who have a specific type of cancer. They are written by European experts representing all disciplines involved in cancer care. ERQCC papers give oncology teams, patients, policymakers and managers an overview of the elements needed in any healthcare system to provide high quality of care throughout the patient journey. References are made to clinical guidelines and other resources where appropriate, and the focus is on care in Europe.

Melanoma: ESSENTIAL REQUIREMENTS FOR QUALITY CARE: CONCLUSION: Taken together, the information presented in this paper provides a comprehensive description of the essential requirements for establishing a high-quality service for melanoma. The ERQCC expert group is aware that it is not possible to propose a 'one size fits all' system for all countries, but urges that access to multidisciplinary teams and specialised treatments is guaranteed to all patients with melanoma.

Circulating levels of VEGFR-1 and VEGFR-2 in patients with metastatic melanoma treated with chemoimmunotherapy alone or combined with bevacizumab.

Melanoma Res 2011 Oct;21(5):431-7

Department of Oncology and Radiotherapy, University of Turku, Turku University Hospital, Finland.

There are no identified biomarkers that could predict response to antiangiogenic or traditional chemoimmunotherapy in metastatic melanoma. We hypothesized that soluble angiogenic factor receptors might help us to identify patients responsive to treatment. A series of 48 patients with stage IV melanoma participating in two phase II clinical trials were included. The trials included treatment with carboplatin, vinorelbine, and subcutaneous interleukin-2 (n=22) or treatment with bevacizumab, dacarbazine, and low-dose interferon-α2a (n=26).Serum samples were prospectively collected and soluble vascular endothelial growth factor receptor 1 (s-VEGFR-1) and 2 (s-VEGFR-2) were measured before starting the trial treatment and during response evaluation.There was a trend toward longer overall survival among patients with higher-than-median serum VEGFR-1 levels (21.3 months) compared with 12.3 months in patients with low pretreatment s-VEGFR-1 levels (P=0.146). Pretreatment s-VEGFR-2 levels did not correlate to survival. Serum VEGFR-2 levels decreased during therapy in 44% of the patients and increased in 56% of the patients. VEGFR-2 increased in 78% (14 of 18) of the patients who progressed during therapy (P=0.017). VEGFR-2 decrease was associated with clinical benefit in 65% of the patients (11 of 17) and with progression in only four patients (P=0.016).High pretreatment levels of s-VEGFR-1 are associated with improved prognosis among patients with metastatic melanoma independently on therapy, whereas increased VEGFR-2 levels during therapy are associated with disease progression. These markers might be useful in selecting patients responsive to antiangiogenic therapy.

[Are immunological treatments beneficial for malignant melanoma of the skin?].

Duodecim 2010 ;126(14):1701-10

TYKS, syöpätautien klinikka PL 52, 20521 Turku.

Treatment results of metastatic malignant melanoma of the skin have failed to exhibit significant improvement for 30 years. Owing to the poor efficiency of cytotoxic therapies, attention has focused on the patient's own immune system and its strengthening or "teaching" to counteract the melanoma tissue. The most significant forms of immunotherapy currently include the interferons, interleukin-2 and antibody therapy directed against a specific T-lymphocyte associated antigen (CTLA-4). So far, therapeutic vaccines for melanoma have not ended up into routine clinical use.

Detection of melanoma-derived cancer-testis antigen CT16 in patient sera by a novel immunoassay.

Int J Cancer 2011 May;128(10):2382-92

Department of Biochemistry and Food Chemistry, University of Turku, Turku, Finland.

Cancer-testis antigens (CTAs) are expressed mainly in various cancer tissues and in testis or placenta. Because of their restricted expression pattern, the CTAs can be potentially used for vaccine development and diagnostic applications. CTA CT16 has been found to be expressed in lung and renal cancers as well as in melanomas. Detection of CT16 protein directly from patient serum could facilitate monitoring of tumor growth and response to therapy in CT16-positive patients. A highly sensitive time-resolved fluorescence-based immunoassay measuring CTA CT16 in serum was developed. Generally, CTAs have not been measured directly from body fluids. CT16 level was detectable in 14 of 23 (61%) patients with metastatic melanoma, whereas none of the nine healthy volunteers collected by us had measurable CT16 level. For an unknown reason, 1 of 20 commercial control serum samples gave a positive result. The Wilcoxon-Mann-Whitney exact test showed statistically significant difference when patients with metastatic melanoma were compared to our control group (p = 0.006) or to the commercial set (p < 0.001). Four melanoma patients had exceptionally high serum CT16 level. CT16 did not correlate either with S100B, a recognized marker of progressing melanoma, or with unspecific serum marker lactate dehydrogenase. Elevation of CT16 titers preceded or followed the clinical diagnosis of disease progression in four patients with metastatic melanoma. As a conclusion, our results show that CT16 protein can be measured directly from patient serum, and the developed assay has a potential for clinical use.

A phase II trial of bevacizumab with dacarbazine and daily low-dose interferon-alpha2a as first line treatment in metastatic melanoma.

Melanoma Res 2010 Aug;20(4):318-25

Department of Oncology and Radiotherapy, University of Turku and Turku University Hospital, Turku, Finland.

Metastatic melanomas are hypervascular tumours with poor prognosis. We hypothesized that treatment of metastatic melanoma with a combination of bevacizumab, a monoclonal antibody against vascular endothelial growth factor, dacarbazine (DTIC) and low-dose interferon alpha-2a (IFN-alpha2a) might lead to a synergistic inhibition of angiogenesis and regression of tumours. Patients with metastatic melanoma were treated with bevacizumab (5 mg/kg every 2 weeks), DTIC (200 mg/m days 1-5 every 4 weeks) and IFN-alpha2a (three MIU subcutaneously daily from day 15 onwards). Patients exhibiting response or stable disease after 6 months were treated with bevacizumab+/-IFN-alpha2a until disease progression. The primary study objectives were progression-free survival (PFS), overall survival and safety. Twenty-six patients were accrued. Response rate was 23% (two complete responses, four partial responses), and six patients showed stable disease. The median PFS for all patients was 2.3 months and for responders 8.1 months. The median overall survival for all patients was 11.5 months. Four life-threatening adverse events were seen: two pulmonary thromboembolisms, an intracerebral haemorrhage, and one grade 4 hypertension. One of the pulmonary emboli and the intracerebral haemorrhage were observed > or =3 months after the last bevacizumab-DTIC dose. Serum matrix metalloproteinase-9 and vascular endothelial growth factor levels changed during therapy. There was a trend towards favourable PFS among patients with only minimal or moderate change in these marker expression levels. The present regimen was active in this patient group but was also associated with remarkable vascular events.

Carboplatin and vinorelbine combined with subcutaneous interleukin-2 in metastatic melanoma with poor prognosis.

Anticancer Res 2009 May;29(5):1755-9

Department of Oncology, Tampere University Hospital, P.O.B 2000, 33521 Tampere, Finland.

Background: The treatment results of metastatic melanoma are miserable if the tumor has spread beyond the soft tissue and lung, in particular, if dacarbazine (DTIC)-based therapy has failed. Platinum analogs and vinca alkaloids have shown some activity in melanoma. Interleukin-2 (IL-2) may augment the efficacy of chemotherapy.

Patients And Methods: A prospective phase II pilot study was conducted to evaluate the efficacy and tolerability of a regimen which contained carboplatin (450 mg/m(2) on day 1), vinorelbine (30 mg/m(2) on day 1) and IL-2 (9 MU subcutaneously once daily on days 2-5 and 9-12) in metastatic melanoma. Twenty-two patients (11 men, 11 women; median age 56 years) were eligible, of whom 13 had cutaneous, 6 ocular and 3 unknown primary melanoma. Seventeen patients (77%) had liver metastases and an equal number had received prior chemotherapy and/or interferon-alfa for recurrent disease.

Results: One partial response was recorded, yielding a response rate of 4.5% . Nine patients had stable disease for a median of 6.0 months (range 3.0-8.6 months). The median time to progression for all patients was 1.8 months (range 0.7-8.6 months) and the median survival was 7.2 months (range 1.4-42.0 months). Toxicity was moderate but manageable. Myelosuppression was the most significant adverse event.

Conclusion: This regimen may offer clinical benefit for melanoma patients with poor prognosis as second-line therapy after DTIC has failed.

Serum angiogenin levels predict treatment response in patients with stage IV melanoma.

Clin Exp Metastasis 2007 29;24(7):567-74. Epub 2007 Aug 29.

Department of Oncology and Radiotherapy, Turku University Hospital, POB 52, Turku 20521, Finland.

This work was conducted to find out new potential serum markers and study their role as predictive factors in patients with metastatic melanoma. Serum samples from 68 patients with stage IV malignant melanoma were collected just before current treatment and screened for 79 different cytokines by using a multi-cytokine array. Angiogenin, which is a protein capable of promoting angiogenesis, was found to be markedly elevated among a sub-group of patients with progressive disease (PD) and thus was subjected to further analysis. The mean serum angiogenin level was 270 ng/ml and the median 236 ng/ml (STD 163 ng/ml). Concentrations were significantly higher among men than in women (P = 0.031), whereas patient's age, site of the primary tumour, Clark's or Breslow's classifications were not associated with angiogenin levels. Patients with only lymph node metastases had markedly lower angiogenin levels than those with metastases at other sites (P = 0.05). High angiogenin levels were significantly (P = 0.015; Kruskal-Wallis) associated with poor treatment response with chemoimmunotherapy. Treatment-related survival (TRS) was shorter (10 months) in patients with above-median values than in those with below-median levels (19 months, P = NS). Cox multivariate regression model was used to control for the confounding by the classical prognostic factors of melanoma (age, sex, disease burden, performance score, site of metastases). Disease burden was the only variable that remained in the model as a significant independent predictor of TRS (P = 0.044). These data suggest that serum angiogenin levels might be of predictive value in the evaluation of treatment response for patients with stage IV melanoma.

The polymorphisms of interleukin-10 gene influence the prognosis of patients with advanced melanoma.

Cancer Genet Cytogenet 2007 Jul;176(1):54-7

Department of Oncology, Tampere University Hospital, P.O.B. 2000, 33521 Tampere, Finland.

The interleukin-10 gene (IL-10) is polymorphic. The genotypes result in inter-individual differences in IL-10 production, which may play a role in the pathophysiology and the clinical course of melanoma and other cancers. We analyzed the frequency of the ATA haplotype formed by the alleles at -1082 (G/A), -819 (C/T), and -592 (C/A) at the promoter region of the IL-10 gene in patients with melanoma (n = 108) and healthy subjects (n = 393). We also studied the long-term prognostic significance of the ATA haplotype carriage. There were significantly more ATA carriers in melanoma patients compared with control subjects (44 vs. 33%, respectively, P = 0.03). In the patients who presented with localized disease, the haplotype carriage was not significantly associated with recurrence rate, disease-free survival, or overall survival. In the patients who presented with or developed advanced disease (n = 36), the ATA haplotype carriage [HR 0.47, 95% confidence interval (CI) 0.22-1.01, P = 0.05] was found statistically significant when adjusted by metastatic sites (HR 4.63, 95% CI 1.88-11.44, P = 0.0009) in multivariate analysis for survival. ATA haplotype carriage appears to increase the susceptibility to melanoma. This is not a significant prognostic factor in localized melanoma, but in advanced disease, it implies longer survival.

Serum VEGF-C is associated with metastatic site in patients with malignant melanoma.

Acta Oncol 2007 ;46(5):678-84

Department of Oncology and Radiotherapy, Turku University Hospital, Turku, Finland.

Vascular endothelial growth factor-C (VEGF-C) is involved in lymphatic metastatic spread. Metastatic site is a prognostic factor in melanoma. We assessed whether serum levels of VEGF-C are associated with metastatic sites or prognosis in patients treated for stage IV melanoma. The study included 64 patients, who received dacarbazine or four-drug chemotherapy (dacarbazine, vincristine, bleomycin and lomustine; BOLD) both combined with interferon-alfa. Serum samples for VEGF-C were analyzed by ELISA. The patients (n =22) with only skin and subcutaneous metastases had significantly lower mean VEGF-C levels (1 643 pg/ml) then the patients (n =42) with other distant metastases (2 584 pg/ml, Mann-Whitney, p =0.033). VEGF-C levels above the median (1 590 pg/ml) were significantly related to deep lymph node involvement (OR 3.763; 95% CI 1.038 - 13.646, p =0.034). There were no other significant associations between VEGF-C levels and tumour burden, nor were the levels significantly related to the response to therapy or survival. Those eight patients, who had received previous adjuvant IFN-alfa therapy had lower mean VEGF-C levels (1 738 pg/ml) as compared to those 56 patients without previous IFN-alfa therapy (2 335 pg/ml, ANOVA, p =0.026). This is the first study exploring serum VEGF-C in melanoma. VEGF-C might be involved in the deep lymphatic dissemination and progression of melanoma metastasis.

Randomized trial of dacarbazine versus bleomycin, vincristine, lomustine and dacarbazine (BOLD) chemotherapy combined with natural or recombinant interferon-alpha in patients with advanced melanoma.

Melanoma Res 2005 Aug;15(4):291-6

Department of Oncology, University of Tampere and Tampere University Hospital, Tampere, Finland.

This randomized phase II study was designed to compare the efficacy and tolerability of dacarbazine (DTIC) and bleomycin, vincristine, lomustine and DTIC (BOLD) combined with natural interferon-alpha (nIFN-alpha) or recombinant interferon-alpha2b (rIFN-alpha2b) in patients with advanced melanoma. The treatment arms were: A, DTIC plus nIFN-alpha; B, BOLD plus nIFN-alpha; C, DTIC plus rIFN-alpha2b; D, BOLD plus rIFN-alpha2b. One hundred and eight patients were randomized, of whom 106 were eligible to be analysed for efficacy. Overall, 56% of patients had abdominal visceral and/or bone involvement. The response rates were 8% (2/25) in arm A, 13% (4/31) in arm B, 12% (3/25) in arm C and 24% (6/25) in arm D. The differences were not statistically significant by the usual chi-squared test. However, when analysed using the Cochran-Armitage trend test, the one-sided P values were close to significant (0.085 and 0.033). All of the eight complete responses occurred in patients with soft tissue and/or lung metastases and the BOLD regimens produced six of them. There were no significant differences in survival (arm A, 11.1 months; arm B, 9.8 months; arm C, 9.1 months; arm D, 7.5 months; P=0.62). BOLD was more toxic than DTIC. With the present sample size, there were no statistically significant differences in efficacy between the arms, but there was a trend towards a higher response rate with BOLD plus rIFN-alpha2b. Patients with soft tissue or lung metastases may achieve more complete responses with BOLD regimens.

High serum levels of matrix metalloproteinase-9 and matrix metalloproteinase-1 are associated with rapid progression in patients with metastatic melanoma.

Clin Cancer Res 2005 Jul;11(14):5158-66

Department of Oncology and Radiotherapy, Turku University Hospital, Finland.

Purpose: Matrix metalloproteinases (MMP) are proteolytic enzymes that play an important role in various aspects of cancer progression. In the present work, we have studied the prognostic significance of serum levels of gelatinase B (MMP-9), collagenase-1 (MMP-1), and collagenase-3 (MMP-13) in patients with advanced melanoma.

Experimental Design: Total pretreatment serum levels of MMP-9 in 71 patients and MMP-1 and MMP-13 in 48 patients were determined by an assay system based on ELISA. Total MMP levels were also assessed in eight healthy controls. The active and latent forms of MMPs were defined by using Western blot analysis and gelatin zymography.

Results: Patients with high serum levels of MMP-9 (> or = 376.6 ng/mL; n = 19) had significantly poorer overall survival (OS) than patients with lower serum MMP-9 levels (n = 52; median OS, 29.1 versus 45.2 months; P = 0.033). High MMP-9 levels were also associated with visceral or bone metastasis (P = 0.027), elevated serum alkaline phosphatase level (P = 0.0009), and presence of liver metastases (P = 0.032). Serum levels of MMP-1 and MMP-13 did not correlate with OS. MMP-1 and MMP-9 were found mainly in latent forms in serum, whereas the majority of MMP-13 in serum was active (48 kDa) form. MMP-13 was found more often in active form in patients (mean, 99% of the total MMP-13 level) than in controls (mean, 84% of the total MMP-13 level; P < 0.0001). After initiating the therapy, patients with elevated levels of MMP-1 (> or = 29.8 ng/mL, n = 10) progressed more rapidly than patients with lower levels (median, 1.9 versus 3.5 months; P = 0.023). Serum levels of MMP-9 and MMP-13 did not correlate with the time to progression (TTP). In multivariate analysis with age and gender, MMP-9 or MMP-1 turned out to be independent prognostic factors for OS [P = 0.039; hazard ratio (HR), 1.8; 95% confidence interval (95% CI), 1.03-3.3] or TTP (P = 0.023; HR, 2.7; 95% CI, 1.15-6.4), respectively.

Conclusions: Our findings provide evidence that MMP-1, MMP-9, and MMP-13 play important roles at different phases of metastatic melanoma spread and that serum MMP-9, in particular, could have clinical value in identifying patients at high risk for melanoma progression.
