- Data in the literature demonstrates increased receptor-mediated uptake of low density lipoprotein (LDL) in many types of malignant cells compared with normal cells. In acute leukemia, an inverse correlation has been demonstrated between disease activity and plasma cholesterol. To explore whether this is true also for ovarian cancer a case-control study was performed. We serially collected blood samples and assayed serum cholesterol and apolipoprotein B (the receptor recognizing moiety of LDL) in 10 patients with ovarian cancer. At diagnosis, the patients had lower mean cholesterol levels compared with 6 healthy women. An increase was found after primary surgery and after successful initial chemotherapy. The 5 patients who are in complete remission after a mean follow-up time of 79 months had higher cholesterol and apolipoprotein B levels at their last visit than at diagnosis. In contrast, a reduction of the two analytes was found in the patients who died from their ovarian cancer 15 to 28 months after diagnosis. The results may open a possibility for targetted chemotherapy in ovarian cancer with LDL as a drug carrier.

- BackgroundCost-effectiveness is important in the prioritisation between interventions in health care. Exercise is cost-effective compared to usual care during oncological treatment; however, the significance of exercise intensity to the cost-effectiveness is unclear. In the present study, we aimed to evaluate the long-term cost-effectiveness of the randomised controlled trial Phys-Can, a six-month exercise programme of high (HI) or low-to-moderate intensity (LMI) during (neo)adjuvant oncological treatment.MethodsA cost-effectiveness analysis was performed, based on 189 participants with breast, colorectal, or prostate cancer (HI: n = 99 and LMI: n = 90) from the Phys-Can RCT in Sweden. Costs were estimated from a societal perspective, and included cost of the exercise intervention, health care utilisation and productivity loss. Health outcomes were assessed as quality-adjusted life-years (QALYs), using EQ-5D-5L at baseline, post intervention and 12 months after the completion of the intervention.ResultsAt 12-month follow-up after the intervention, the total cost per participant did not differ significantly between HI (€27,314) and LMI exercise (€29,788). There was no significant difference in health outcome between the intensity groups. On average HI generated 1.190 QALYs and LMI 1.185 QALYs. The mean incremental cost-effectiveness ratio indicated that HI was cost effective compared with LMI, but the uncertainty was large.ConclusionsWe conclude that HI and LMI exercise have similar costs and effects during oncological treatment. Hence, based on cost-effectiveness, we suggest that decision makers and clinicians can consider implementing both HI and LMI exercise programmes and recommend either intensity to the patients with cancer during oncological treatment to facilitate improvement of health.

- BACKGROUND: Exercise during oncological treatment is beneficial to patient health and can counteract the side effects of treatment. Knowledge of the societal costs associated with an exercise intervention, however, is limited. The aims of the present study were to evaluate the long-term resource utilisation and societal costs of an exercise intervention conducted during (neo)adjuvant oncological treatment in a randomised control trial (RCT) versus usual care (UC), and to compare high-intensity (HI) versus low-to-moderate intensity (LMI) exercise in the RCT.METHODS: We used data from the Physical Training and Cancer (Phys-Can) project. In the RCT, 577 participants were randomised to HI or to LMI of combined endurance and resistance training for 6 months, during oncological treatment. The project also included 89 participants with UC in a longitudinal observational study. We measured at baseline and after 18 months. Resource utilisation and costs of the exercise intervention, health care, and productivity loss were compared using analyses of covariance (RCT vs. UC) and t test (HI vs. LMI).RESULTS: Complete data were available for 619 participants (RCT HI: n = 269, LMI: n = 265, and UC: n = 85). We found no difference in total societal costs between the exercise intervention groups in the RCT and UC. However, participants in the RCT had lower rates of disability pension days (p < .001), corresponding costs (p = .001), and pharmacy costs (p = .018) than the UC group. Nor did we find differences in resource utilisation or costs between HI and LMI exercise int the RCT.CONCLUSION: Our study showed no difference in total societal costs between the comprehensive exercise intervention and UC or between the exercise intensities. This suggests that exercise, with its well-documented health benefits during oncological treatment, produces neither additional costs nor savings.

- Introduction. In palliative cancer care, when approaching death, swallowing difficulties and the burden of tablet intake frequently makes us reconsider each individual drug prescribed. Through the last two decades the routine of always combining a strong opioid with paracetamol has been widely spread in Sweden. Clinical experience has challenged this routine as many patients seem to manage equally well without paracetamol. To find out whether this might be of clinical importance, we wanted to perform a more systematic registration. Material and methods. Thirty-four incurable cancer patients with well controlled pain (NRS 4), treated by specialised palliative home care teams, with ongoing medication with the strong opioid paracetamol combination was recruited to this prospective clinical study. The effect of completely stopping paracetamol medication was evaluated four days later at follow-up. Results. At follow-up nine patients (26%) felt more pain compared to when they entered the study, two patients (6%) felt less pain and 23 (68%) felt no difference. When asked about their preference about future paracetamol treatment 18 patients (53%) wanted to stop taking it, six patients (18%) wanted to continue with regular paracetamol medication as before, and ten patients (29%) wanted to take paracetamol as needed. No clinical predictors of paracetamol response could be identified. Discussion. The results of this study indicate that a critical evaluation, in every patient, of the subjective additive analgesic effect of paracetamol in concurrent strong opioid therapy is advisable and that stopping paracetamol medication not necessarily implies increased pain. Rather in some patients the cessation of paracetamol medication is experienced as a relief as pain control is maintained with a lesser tablet burden.

- Background. Our aim was to determine the efficacy of a therapeutic schedule including external radiation and brachytherapy in a consecutive and retrospective series of tonsillar carcinoma patients. Patients and methods. Ninety-six patients with tonsillar carcinoma were treated between 1988 and 2000 and were followed up for at least for three years. All patients were treated with accelerated hyperfractionated external radiotherapy, 68 patients had additional brachytherapy and 69 patients with advanced stages also received chemotherapy. There was no planned surgery even though 73% had N+ disease. Eleven patients with persistent neck nodes underwent ultimate salvage surgery. Results. The overall three-year survival (OS) was 70%. OS for the T stage was T1 90%, T2 89%, T3 54% and T4 60%. The corresponding numbers for the N stage were N0 61.5%, N1 73%, N2 78% and N3 66%. Accordingly OS was influenced by the T stage (p>0.001) rather than by N stage. Only four patients with salvage surgery had viable tumour cells in the specimen, their survival was not inferior. Discussion. The primary tumour stage is an essential determinant for survival in patients with irradiated tonsillar carcinoma. Neck dissection should be confined only as a salvage procedure.
