Long-term outcomes of adults with first-relapsed/refractory systemic anaplastic large-cell lymphoma in the pre-brentuximab vedotin era: A LYSA/SFGM-TC study.

BACKGROUND: Long-term outcomes of adults with first-relapsed/refractory (R/R) systemic anaplastic large-cell lymphoma (ALCL) are not definitively established and should be evaluated. PATIENTS AND METHODS: We previously published the long-term outcomes of adults with ALCL initially treated with polychemotherapy in LYmphoma Study Association (LYSA) prospective clinical trials conducted during the pre-brentuximab vedotin era. Herein, we report the long-term outcomes of those patients after the first-relapsed/refractory (R/R) events. RESULTS: Among the 138 (64 (anaplastic lymphoma kinase (ALK(+)) and 74 ALK(-) ALCL) adults initially treated in clinical trials, 40 (14 ALK(+) and 26 ALK(-)) first-R/R ALCL patients and their long-term outcomes were analysed. Median follow-up from the first-R/R events was 12.5 years. For ALK(+) and ALK(-) patients, respectively, median [range] findings were as follows: age at first-R/R event: 35 [19-76] and 61 [34-81] years; time between inclusion in first-line clinical trials and first-R/R events was 6 [1.5-34] and 11.1 [1-67] months (P = 0.36); with median (95% confidence interval) progression-free survival after the first-R/R events: 3.8 (0.7-14.8) and 5.3 (2.4-8.4) months (P = 0.39); and overall survival: 13.6 (0.7-89) and 8.1 (3.3-25) months (P = 0.96). ALCL was the main cause of death. CONCLUSION: Most adults with first-R/R ALCL have poor outcomes, with no significant differences between patients with ALK(+) or ALK(-) disease. These results could be used as reference for the evaluation of new drugs to treat R/R ALCL.

Identification of intra-hepatic communicating veins through the arch sign on CT-scan.

PURPOSE: Knowledge of vascular outflow is essential in liver surgery. Communicating veins between the right hepatic vein (RHV) and the middle hepatic vein (MHV) have been described and allowed us to perform new surgical procedures. The aim of this study was to predict the existence of intra-hepatic venous anastomosis by identifying communicating veins on 2D CT-scan imaging. METHODS: We retrospectively analysed data from 32 patients operated on for liver tumours between 2004 and 2013 who underwent a bisegmentectomy VI-VII enlarged to the RHV and/or a bisegmentectomy VII-VIII and/or a left hepatectomy enlarged to the MHV and who had pre and post-operative CT-scans. Patients with cirrhosis were excluded. We first analysed post-operative images and, in patients with a proven collateral vein, looked for evidence of this on pre-operative imaging. We then validated this pre-operative sign against post-operative imaging. RESULTS: Collaterals from both the RHV and the MHV formed an arch visible on pre-operative imaging which predicted the development of intrahepatic venous anastomosis in 20 patients. In 14 patients, a perfect match between the arch sign and development of collaterals was observed (n = 28). Sensitivity, specificity, negative and positive predictive values were 87, 80, 80, and 87%, respectively. Positive and negative likelihood ratio tests were 4.3 and 0.16, respectively. CONCLUSION: Communicating veins between the RHV and the MHV are frequent and can be predicted by the arch sign on 2D CT-scan. Hence the arch sign can be very useful when planning liver surgery.

Long-term response and postsurgical complete remissions after treatment with sunitinib malate, an oral multitargeted receptor tyrosine kinase inhibitor, in patients with metastatic renal cell carcinoma.

Receptor tyrosine kinase (RTK) inhibitors have revolutionized the treatment of metastatic renal cell carcinoma (mRCC) and significantly extended survival in these patients. Sunitinib is an oral multitargeted inhibitor of vascular endothelial growth factor receptors (VEGFRs-1, -2, and -3), platelet-derived growth factor receptors (PDGFRs-α and -ß), stem-cell factor receptor (KIT), FMS-like tyrosine kinase 3 (FLT3), colony-stimulating factor 1 receptor (CSF-1R), and glial cell line-derived neurotrophic factor receptor (REarranged during Transfection; RET). Sunitinib is approved multinationally for the treatment of advanced RCC, and is considered the reference standard of care for first-line treatment. In clinical trials, sunitinib has been associated with a consistent, distinct profile of adverse events. Here we describe three cases that show that it is possible to manage adverse events occurring during sunitinib therapy, and thus allow patients with mRCC to receive an effective dose of sunitinib in order to achieve long-term disease control. These cases also show that surgical resection, performed whenever possible, can help to improve control of metastatic disease and so avoid the unnecessary toxicity and high costs of prolonged antiangiogenic therapy.
