Refinement in supportive care also may have an important role in survival because improved supportive measures contribute to the decreased early mortality.

Am J Med 1996; 100: 290–298. If treatment-related mortality remains around 15%, it will be extremely difficult to power a study to detect an advantage over standard chemotherapy, which has treatment-related mortalities less than 5%.34 Experience of the treatment center has been shown to be an important predictor of outcome after auto-SCT in amyloidosis. Survival in patients with primary systemic amyloidosis and raised serum cardiac troponins. For patients who undergo a bone marrow transplant, the 100th day after the procedure is an important milestone. In this study, we report 422 patients who received auto-SCT for AL amyloidosis to compare outcomes of patients treated before January 2006 with those treated from January 2006 to 1 December 2009. A hundred days after her bone marrow transplant, 24-year-old Suleika Jaouad celebrates a big milestone in her fight against leukemia. In this study, 422 consecutive patients with AL amyloidosis received auto-SCT during the study period. Thank you for visiting nature.com. Gertz MA, Ansell SM, Dingli D, Dispenzieri A, Buadi FK, Elliott MA et al. Day 100 all-cause mortality in the Pre- and Post-2006 auto-SCT groups is shown in Figure 1. Mollee PN, Wechalekar AD, Pereira DL, Franke N, Reece D, Chen C et al. In the Pre-2006 auto-SCT group, factors that were significantly different between those who survived through day 100 (n=233) and those who did not (n=32) were interventricular septal thickness (12 vs 14 mm, P=0.003), frequency of cardiac involvement by consensus criteria (47 vs 75%, P=0.004), one-organ involvement (52 vs 22%, P=0.001) and serum values of albumin (2.86 vs 2.22 g per 100 mL, P=0.007), troponin T (0.01 vs 0.025 ng/mL, P<0.001), β2-microglobulin (2.44 vs 3.11 mg/L, P=0.001) and 24-h urine total protein (3.31 vs 6.24 g/d, P=0.04). Long-term follow-up of plasma cells in bone marrow and serum free light chains in primary systemic AL amyloidosis. Treatment with oral melphalan plus dexamethasone produces long-term remissions in AL amyloidosis.

Gertz MA, Leung N, Lacy MQ, Dispenzieri A, Zeldenrust SR, Hayman SR et al. At Mayo Clinic, not more than 20–25% of patients seen in consultation are eligible for consideration of auto-SCT. Note that the survival scale ranges from 70 to 100%. Bone Marrow Transplant 46, 970–975 (2011). N Engl J Med 2007; 357: 1083–1093. Primary systemic amyloidosis: comparison of melphalan/prednisone versus colchicine. No patients were excluded from this analysis. Palladini G, Perfetti V, Perlini S, Obici L, Lavatelli F, Caccialanza R et al. Comenzo RL, Vosburgh E, Falk RH, Sanchorawala V, Reisinger J, Dubrey S et al. The lowest number of stem cells infused was 1.98 × 106 CD34+ cells/kg. The BM shows almost no disease, with an average tumor burden of 5% in plasma cells,11, 12 whereas organ dysfunction is frequently severe. However, this did not achieve statistical significance, most likely because the study was underpowered, with only 11 deaths occurring over a 4-year period. See all of the videos in the Life, Interrupted series here. Intern Med 2005; 44: 428–433. Comenzo RL, Sanchorawala V, Fisher C, Akpek G, Farhat M, Cerda S et al. The exclusions most typically are related to age, New York Heart Association class III or IV cardiac failure, chronic kidney disease stage IV, significant three-organ involvement and previous cumulative melphalan exposure, making successful stem-cell procurement highly unlikely. Thx to everyone on 5 West for putting up with a sometimes moody patient and to all of you for your comments and to my friends who texted me.

Survival at 2 years increased from 78 to 82%.

Palladini G, Russo P, Nuvolone M, Lavatelli F, Perfetti V, Obici L et al. As a consequence, patient selection and the center's experience in the application of myeloablative therapy become paramount in preventing unacceptable levels of treatment-related mortality.13, 14. Severity of baseline proteinuria predicts renal response in immunoglobulin light chain-associated amyloidosis after autologous stem cell transplantation. (2018), American Journal of Hematology

Mortality rates associated with auto-SCT in AL amyloidosis range from 5% to nearly 40%.20, 21, 22 Efforts to improve survival in patients with amyloidosis have been facilitated by the introduction of novel agents for the treatment of amyloidosis, including thalidomide,23 lenalidomide24 and bortezomib.25 Melphalan–dexamethasone has been established as a highly effective regimen in patients who are not considered candidates for auto-SCT.26 The median reported survival of 5.1 years using oral chemotherapy in that study makes it difficult to determine the exact role of auto-SCT, if any, in managing AL amyloidosis. The most important change was the development of the Ig free light-chain assay, which allowed a more accurate determination of hematological response.28, 29, 30 Reports on the efficacy of melphalan and prednisone may underestimate the true response rates because none of the studies included light-chain measurements.31, 32 Response rates with novel agent-based therapy are extremely high and rival those seen with auto-SCT.33 It is, therefore, fair to ask whether auto-SCT, given its higher risk, should remain a standard of care for amyloidosis. Association of melphalan and high-dose dexamethasone is effective and well tolerated in patients with AL (primary) amyloidosis who are ineligible for stem cell transplantation. Treatment of 100 patients with primary amyloidosis: a randomized trial of melphalan, prednisone, and colchicine versus colchicine only.

In a review of outcomes from multiple centers, the median survival of patients with amyloidosis selected for SCT exceeded 80 months.4, 5 Reviews from Mayo Clinic,6 Boston Medical Center5 and Memorial Sloan-Kettering Cancer Center (New York, NY, USA)7 showed median survivals of 86 months, 55 months and not reached, respectively, which suggests major differences in patient selection criteria for transplant. To obtain Delayed platelet recovery (DPR) beyond the expected time occurs in 5% to 37% of HSCT patients. The combination of thalidomide and intermediate-dose dexamethasone is an effective but toxic treatment for patients with primary amyloidosis (AL). Initially, we administer a single dose of 10 mcg/kg of G-CSF per day for 4 days. Others have reported high treatment-related mortality for patients with AL amyloidosis treated with novel agents. Just in time for Father's Day, MAJIC 100 morning host Stuntman Stu Schwartz is leaving the hospital to, in his words, "annoy my wife and kids" after his latest bone marrow transplant. Suleika Jaouad writes about the challenges faced by young adults and her experiences with cancer. CAS  Deshmukh M, Elderfield K, Rahemtulla A, Naresh KN . All patients had biopsy-proven amyloidosis. Although the only official change in our selection criteria was the addition of a cutoff for troponin T values, our tolerance for a ‘physiological’ age of 70 years has become stricter and our willingness to classify an organ as ‘significantly’ involved has increased. Tezcan AZ, Tezcan H, Gastineau DA, Armitage JO, Haire WD. The activity of lenalidomide with or without dexamethasone in patients with primary systemic amyloidosis. This difference has not yet achieved statistical significance, but recognition of this decrease in mortality is important for physicians caring for these patients, as they weigh the pros and cons of auto-SCT vs novel agent-based treatment in management of amyloidosis. The decrease in treatment-related mortality and the improved 2-year survival we report herein are encouraging and represent a justification for the continued exploration of the role of auto-SCT in AL amyloidosis.
