RESUMO

BACKGROUND: Sarcomas are rare cancers with great variability in clinical and histopathological presentation. The main objective of clinical practice guidelines (CPGs) is to standardize diagnosis and treatment. METHODS: From March 2005 to February 2007, all patients diagnosed with localized sarcoma in the Rhône-Alpes region were included in a cohort-based study, to evaluate the compliance of sarcoma management with French guidelines in routine practice and to identify predictive factors for compliance with CGPs. RESULTS: 634 (71 %) patients with localized sarcoma satisfying the inclusion criteria were included out of 891 newly diagnosed sarcomas. Taking into account initial diagnosis until follow-up, overall conformity to CPGs was only 40 % [95 % confidence interval (CI) = 36-44], ranging from 54 % for gastrointestinal stromal tumor to 36 % for soft tissue sarcoma and 42 % for bone sarcoma. In multivariate analysis, primary tumor type [relative risk (RR) = 4.42, 95 % CI = 2.79-6.99, p < 0.001], dedicated multidisciplinary staff before surgery (RR = 4.19, 95 % CI = 2.39-7.35, p < 0.001) and management in specialized hospitals (RR = 3.71, 95 % CI = 2.43-5.66, p < 0.001) were identified as unique independent risk factors for conformity to CPGs for overall treatment sequence. CONCLUSIONS: With only 40 % of total conformity to CPGs, the conclusions support the improvement of initial sarcoma management and its performance in specialized centres or within specialized dedicated networks.

RESUMO

AIM: The French Sarcoma Group performed this retrospective analysis of the 'RetrospectYon' database with data of patients with recurrent advanced soft tissue sarcoma (STS) treated with trabectedin 1.5 mg/m(2) as a 24-h infusion every three weeks. METHODS: Patients who achieved non-progressive disease after six initial cycles could receive long-term trabectedin treatment until disease progression. RESULTS: Overall, 885 patients from 25 French centres were included. Patients received a median of four trabectedin cycles (range: 1-28). The objective response rate was 17% (six complete/127 partial responses) and 50% (n = 403) of patients had stable disease for a disease control rate of 67%. After a median follow-up of 22.0 months, median progression-free survival (PFS) and overall survival (OS) were 4.4 and 12.2 months, respectively. After six cycles, 227/304 patients with non-progressive disease received trabectedin until disease progression and obtained a significantly superior median PFS (11.7 versus 7.6 months, P<0.003) and OS (24.9 versus 16.9 months, P < 0.001) compared with those who stopped trabectedin treatment. Deaths and unscheduled hospitalisation attributed to drug-related events occurred in 0.5% and 9.4% of patients, respectively. CONCLUSION: The results of this real-life study demonstrate that treatment with trabectedin of patients with STS yielded comparable or improved efficacy outcomes versus those observed in clinical trials. A long-term treatment with trabectedin given until disease progression is associated with significantly improved PFS and OS.

RESUMO

Rare cancer issues have not been much explored yet because of their low incidence. That is why epidemiological studies have difficulties in identifying indisputable etiological risk factors. An expert opinion, mainly concentrated in some establishments, is required for these cancers' management. However, on account of the potential remoteness of these therapeutic resources, the patients' way of care remains also unstudied. By means of a geographical analysis of a regional exhaustive cohort of sarcoma, diagnosed in 2006 and 2007 and followed during five years at least, we can make progress on these different issues. Gastro-Intestinal and Stromal Tumors (GIST) occur more frequently in privileged territories while liposarcomas arise in more deprived areas. The association between liposarcomas and areas deprivation is significant (P=0.05). Moreover, pre-operative biopsy and some clinical patient characteristics, age, grade or tumor localization, are associated with an increase in the distance covered by patients for the first-line treatment (p ≤ 0,001). In the scope of an interdisciplinary collaboration, the geographical approach develops some hypothesis for rare cancers research, which must be tested by other larger scale studies.

RESUMO

PURPOSE: To report two cases of choroidal neovascular membrane associated with optic disc drusen which were successfully treated using argon laser photocoagulation. METHODS: Choroidal neovascular complications of optic disc drusen were diagnosed in two of our patients, a 36-year-old woman and a 14-year-old girl. In both cases visual acuity was 20/100 in the affected eye. Fundus examination and angiography revealed a choroidal neovascular membrane. Computer tomography identified bilateral calcified drusen of the optic discs. Photocoagulation of neovascular tissues was immediately performed. RESULTS: Visual acuity improved progressively, reaching 20/20 10 months after treatment in one case and 20/30 in the other. No recurrence was observed during follow-up. CONCLUSION: Early diagnosis and immediate laser photocoagulation of vision-threatening choroidal neovascular membranes associated with optic disc drusen helps stop progression towards the macula and improves longterm visual acuity.
