Off-label use of targeted therapies in osteosarcomas: data from the French registry OUTC'S (Observatoire de l'Utilisation des Thérapies Ciblées dans les Sarcomes):

BACKGROUND: The objective of this study is to explore the off-label use of targeted therapies (TTs) for patients with osteosarcoma registered within the French Sarcoma Group--Bone Tumor Study Group (GSF-GETO) national registry. METHODS: All patients with an osteosarcoma, registered between January 1, 2009 and July 15, 2013 were analyzed. RESULTS: Twenty-nine patients with refractory relapsed osteosarcomas received 33 treatment lines of TTs. The median age at the beginning of treatment was 19 years (range 9-72). The median number of previous lines of chemotherapy was 3 (range 1-8). Before inclusion, 3 patients were in second complete remission, 26 were in progression for metastatic relapse. Twenty-three patients received sirolimus (in combination with cyclophosphamide for 18); 5, sunitinib; 4, sorafenib; and one, pazopanib. Stable disease was observed for 45.5% of patients (95% Confidence Interval (CI) [20-52.8]). The median Progression-Free Survival (PFS) was 3 months (95% CI [2-5.4]) for patients treated by sirolimus and 1.8 months (95% CI [1.3-2.8]) for patients receiving multi-targeted tyrosine kinase inhibitors; 6-month PFS 15%. The median Overall Survival (OS) was 6.8 months (95% CI [4.7-12.1]), and one-year OS was 24%. In a multivariate analysis, PFS was superior for patients receiving sirolimus compared to other TTs (Hazard Ratio (HR) = 2.7, 95% CI [1.05-7.1]). No toxic death was reported. Grade 3 and 4 toxicities were observed in 27 and 6% of cases respectively. CONCLUSION: Off-label TTs, especially sirolimus, reported benefit in the treatment of refractory osteosarcomas with an acceptable toxicity profile, including in pediatric population

A risk-adapted strategy of radiotherapy or cisplatin-based chemotherapy in stage II seminoma

International audienceOBJECTIVES: Indications for radiotherapy and chemotherapy in stage II seminoma are currently debated. MATERIALS AND METHODS: Since 1980, the policy at Institut Gustave Roussy was to treat patients with stage IIA-B disease with external radiotherapy and patients with stage IIB-C with cisplatin-based chemotherapy. In stage IIB disease, 3 cm was the usual tumor size threshold above which individual patients were considered for chemotherapy. RESULTS: During the period 1980-2001, 67 patients with stage II seminoma were treated: stage IIA (n = 5), stage IIB (n = 31), and stage IIC (n = 31). The median age was 40 years (range: 23-64). Among 37 patients who received radiotherapy, 5, 28, and 4 had a stage IIA, IIB, and IIC, respectively. Among 30 patients who received chemotherapy, 27 had a stage IIC. With a median follow-up of 9.4 years, 19 relapses (28%) occurred, including 11 and 8 cases treated with radiotherapy (30%) and chemotherapy (27%), respectively. The 5-year relapse-free survival was 71% (95% CI: 59-80). All but three relapses were salvaged with chemotherapy followed in selected cases by surgical resection of residual masses. Only 3 patients died of seminoma. The 5-year overall survival rate is 97% (95% CI: 89-99). Five patients subsequently developed a non-germ-cell second cancer, which occurred within the radiation field in 3 cases. CONCLUSION: With an overall survival rate of 97%, the overall outcome of patients with stage II seminoma managed according to this risk-adapted strategy is good. The possibility of extending the indications for chemotherapy to selected stage IIB seminoma patients needs to be further evaluated as potentially beneficial in terms of relapse risk

Totally implantable venous access ports: a prospective long-term study of early and late complications in adult patients with cancer

International audiencePURPOSE: Totally implantable venous access ports (TIVAP) have been widely used for many years in the management of patients suffering from cancer. The implantation and long-term use of TIVAPs are associated with mechanical, thrombotic, and infectious complications. This is the first exhaustive prospective study of all complications occurring in a whole population on long-term follow-up and therefore allows an objective assessment to be made of the safety of TIVAPs.METHODS: We carried out a prospective single-center observational study. All adult patients with cancer who had a TIVAP implanted between January 1 and December 31, 2006 were registered. Early and late complications were recorded until the removal of the device, the patient's death, or until December 31, 2013. Exhaustive data concerning patients and TIVAP was recorded at time of implantation.RESULTS: Four hundred and ninety-three TIVAPs were implanted in 483 adult cancer patients and were followed during a period from 1 to 94 months (median = 18 months) representing a global quantity of 367,359 catheter-days. Eighty-seven complications were recorded (0.237/1000 catheter-days), including 37 infections (0.101/1000 catheter-days), 17 thrombotic events (0.046/1000 catheter-days), and 9 extravasations. Out of the 87 events, 62 (71.3%) occurred during the first year after implantation. Events were therefore extremely rare after 1 year. Thromboembolic and infectious complications were rare and no risk factors for these were found.CONCLUSIONS: This study demonstrates excellent tolerability, with only occasional complications. Most of these occurred during the year following implantation. A TIVAP may also be left in place for an extremely long time
