The Scandinavian Sarcoma Group Central Register: 6,000 patients after 25 years of monitoring of referral and treatment of extremity and trunk wall soft-tissue sarcoma.

Purpose - We wanted to examine the potential of the Scandinavian Sarcoma Group (SSG) Central Register, and evaluate referral and treatment practice for soft-tissue sarcomas in the extremities and trunk wall (STS) in the Nordic countries. Background - Based on incidence rates from the literature, 8,150 (7,000-9,300) cases of STS of the extremity and trunk wall should have been diagnosed in Norway, Finland, Iceland, and Sweden from 1987 through 2011. The SSG Register has 6,027 cases registered from this period, with 5,837 having complete registration of key variables. 10 centers have been reporting to the Register. The 5 centers that consistently report treat approximately 90% of the cases in their respective regions. The remaining centers have reported all the patients who were treated during certain time periods, but not for the entire 25-year period. Results - 59% of patients were referred to a sarcoma center untouched, i.e. before any attempt at open biopsy. There was an improvement from 52% during the first 5 years to 70% during the last 5 years. 50% had wide or better margins at surgery. Wide margins are now achieved less often than 20 years ago, in parallel with an increase in the use of radiotherapy. For the centers that consistently report, 97% of surviving patients are followed for more than 4 years. Metastasis-free survival (MFS) increased from 67% to 73% during the 25-year period. Interpretation - The Register is considered to be representative of extremity and trunk wall sarcoma disease in the population of Scandinavia, treated at the reporting centers. There were no clinically significant differences in treatment results at these centers.

Overrepresentation of HLA-DQ2 in small intestinal neuroendocrine tumor patients.

PURPOSE: To investigate whether celiac disease risk haplotypes HLA-DQ2 and DQ8 also increase the risk for developing small intestinal neuroendocrine tumor (SI-NET). METHODS: Thirty-five patients with serotonin-producing jejunal and ileal SI-NET were examined with HLA-DQ genotyping and serology for IgA anti-tissue transglutaminase (tTG) antibodies. RESULTS: Twenty-one patients (60 %) carried HLA-DQ2 or DQ8, twice the frequency of the general population (P < 0.001). In particular DQ2 was overrepresented (P = 0.013). Gender, age, disease stage, histopathological grade, or multifocality of primary tumor did not differ between patients with DQ2 or DQ8 and patients with other HLA-DQ haplotypes. No patient in the study was diagnosed with celiac disease (latent or symptomatic) as anti-tTG antibodies were negative in all 35. CONCLUSION: HLA-DQ haplotypes associated with celiac disease are overrepresented also in patients with SI-NET, in particular HLA-DQ2.

Randomized crossover study in patients with neuroendocrine tumors to assess patient preference for lanreotide Autogel(®) given by either self/partner or a health care professional.

BACKGROUND: Lanreotide Autogel(®) is supplied in prefilled syringes. Therefore, it is possible for patients with neuroendocrine tumors to use self-/partner-administered injections. The primary objective of this study was to assess the proportion of patients preferring self/partner injections over injections administered by health care professionals, and to describe the impact of self/partner administration on efficacy, safety, and costs. METHODS: Of 62 eligible patients, 26 (42%) patients with neuroendocrine tumors treated with a stable dose of lanreotide Autogel 90 mg or 120 mg every 4 weeks agreed to participate in this Phase IV, international, open-label, crossover study, conducted at hospitals in Sweden, Norway, and Denmark. Patients were randomized to two blocks, starting with administration of lanreotide Autogel by either self/partner or a health care professional. Preference for injections administered by self/partner or health care professionals was measured, as well as efficacy, safety, and health care resource utilization (both direct and indirect costs). RESULTS: Of 25 evaluable patients, 22 (88%) preferred self/partner injections, mainly because they experienced increased independence. Based on all patients asked to participate (n = 62), 35% preferred self/partner injections on a regular basis. There was no difference in efficacy or safety between the two administration blocks. CONCLUSION: Many patients with neuroendocrine tumors prefer self/partner injection of lanreotide Autogel, and are able to self/partner inject without any impact on efficacy or safety. This administration method seems to provide a good alternative for suitable patients to increase patient independence and reduce the number of clinic visits.

Acupuncture improves health-related quality-of-life (HRQoL) and sleep in women with breast cancer and hot flushes.

PURPOSE: Evaluate effects of electro-acupuncture (EA) and hormone therapy (HT) on health-related quality-of-life (HRQoL) and sleep in breast cancer survivors with vasomotor symptoms. METHODS: Forty-five women, randomized to EA (n = 27) for 12 weeks or HT (n = 18) for 24 months, were followed for up to 2 years. Distress caused by, and numbers of, hot flushes, hours slept and times woken up/night, Psychological and General Well-being Index (PGWB) and Women's Health Questionnaire (WHQ) were registered before and during treatment and at 6, 9, 12, 18 and 24 months after start of treatment. RESULTS: After 12 weeks of EA (n = 19), WHQ improved from 0.32 (IQR 0.23-0.53) at baseline to 0.24 (IQR 0.12-0.39; p < 0.001) and PGWB from 78 (IQR 53-89) to 79 (IQR 68-93; p = 0.002). All sleep parameters improved and Hot Flush Score (HFS) decreased by 80%. At 12 months, WHQ, PGWB and all sleep parameters remained significantly improved (n = 14) and HFS decreased by 65%. After 12 weeks of HT (n = 18), WHQ improved from 0.29 (IQR 0.15-0.44) at baseline to 0.15 (IQR 0.05-0.22; p = 0.001), PGWB from 75 (IQR 59-88) to 90 (62-97; p = 0.102) and three of five sleep parameters improved. CONCLUSION: Both EA and HT increased HRQoL and sleep, probably through decreasing numbers of and distress by hot flushes. Although flushes decreased less in the EA group than in the HT group, HRQoL improved at least to the same extent maybe due to other effects of EA, not induced by HT, e.g. on anxiety, vitality and sleep, supported by subscale analyses. EA should be further evaluated as treatment for women with breast cancer and climacteric complaints, since HT no longer can be recommended for these women.

Chemotherapy of soft tissue sarcoma--a clinical evaluation of treatment over ten years.

The aim of the study was to evaluate the effect of palliative chemotherapy on soft tissue sarcomas given outside controlled trials. Therapy and response rates of 77 patients with non-resectable sarcoma treated with different regimens between 1991 and 2000 were reviewed. Thirty-six patients were treated with first-line chemotherapy comprising cyclophosphamide+vincristine+doxorubicin+dacarbazine (CYVADIC), with a response rate of 28% (median response duration 5.5 months). Etoposide and ifosfamide (IVP, or VIG, which also includes granulocyte colony-stimulating factor (G-CSF)) were used in the treatment of 18 patients. The response rate was 22% (median response duration 4.5 months); Nineteen patients were treated with doxorubicin+ifosfamide and one patient responded. Four patients received other first-line treatments. Thirty-eight patients were given second-line chemotherapy and 4 (10%) patients responded. Thirteen patients were given third-line treatment and 5 patients received fourth-line treatment, but without any response. Disease progression was the dominant reason for discontinuation of therapy. The response rate in the present study was lower than the best published results, probably due to the fact that our soft tissue sarcoma patient material was unselected. Treatment with CYVADIC yields at least as high a response rate as the more recently described doxorubicin+ifosfamide combination, but third- and fourth-line therapy is not beneficial. Clinical trials with more active drugs are needed, as are more predictive and prognostic tests and a better selection of patient groups suited for different treatment options for soft tissue sarcomas.
