Abstract
Achievement of a normal FLC ratio (FLCr) following treatment indicates hematologic response and suggests better outcomes in light chain amyloidosis (AL). We examined if elevated involved free light chain (hiFLC) impacts outcomes in patients achieving normal FLCr. We retrospectively analyzed 345 AL patients who were diagnosed within a 10-year period (2006-2015) and had 2 consecutive normal FLCr values after 1st line treatment. Among these, patients with hiFLC at 1st reading of normal FLCr (hiFLC1; n = 166; 48.1%) were compared to those who did not (n = 179; 51.9%). Patients with AL who have hiFLC1 after initial therapy had higher rates of multi-organ involvement (63.3 vs 46.4%; P = .002) and patients in advanced Mayo stage (42.9 vs 32.2%; P = .04) at diagnosis. The median progression free survival [PFS; 38.2 (95%CI; 26.4, 55.4) vs 67.1 (95%CI; 55.8, 88) months; P = .0002] and overall survival [OS; 94.4 (95%CI; 78, 107.1) vs not reached (NR, 95%CI; 116.1, NR) months; P < .0001] were lower in those who had hiFLC1. A more stringent comparison for patients with 2 consecutive hiFLC (hIFLC2; n = 111; 32.2%) versus not (n = 2234; 67.8%) showed consistent results [PFS; 27.1 (95%CI; 23, 53.8) vs 63.3 (95%CI; 55.4, 77) months; P < .0001 and OS; 78 (95% CI; 54.6, 98.8) vs NR (95%CI; NR, NR); P < .0001]. This poor prognostic impact of hiFLC on survival was independent of serum creatinine, Mayo stage, negative immunofixation status and inclusion of transplant in initial therapy on multivariate analysis. Hence, persistent elevation of iFLC predicts poor prognosis even among patients achieving normal ratio after initial therapy in AL.

Abstract
We analyzed the outcomes following initial relapse or refractory disease in systemic light chain amyloidosis (AL) and the impact of type of therapy employed.A total of 1327 patients with AL seen at Mayo Clinic within 90 days of diagnosis, between 2006 and 2015, were reviewed. The study included 366 patients experiencing a documented hematological or organ relapse or refractory disease requiring start of second line therapy. Overall survival (OS) and time to next treatment (TTNT) were calculated from start of second line treatment.The median time to require second line treatment was 16.2 months (1-93) from the start of first line therapy. At relapse, patients received proteasome inhibitors (PI; 45.1%), immunomodulators (IMiD; 22.7%), alkylators (9%), PI and IMiD combination (4.1%), autologous transplant (3.8%), steroids and other therapies (4.9%). Among these, 124 (33.9%) required change or reinstitution of therapy. The median time to require third line treatment was 31 months (95% CI; 24, 40.5) and the median overall survival (OS) was 38.8 months (95% CI; 29.6, 52.6) from the start of second line treatment. Retreatment with same therapy at relapse significantly reduced TTNT (22 m vs 32.3 m; P = .01) as compared to different therapy; but did not have any impact OS (30.8 m vs 51.1 m; P = .5). In conclusion, this study provides important information about outcomes of patients with AL who require second line treatment for relapsed/refractory disease . Treatment with a different therapy at relapse improves time to next therapy but does not impact OS.

Abstract
Immunoglobulin light chain amyloidosis (AL) is a rare, complex disease caused by misfolded free light chains produced by a usually small, indolent plasma cell clone. Effective treatments exist that can alter the natural history, provided that they are started before irreversible organ damage has occurred. The cornerstones of the management of AL amyloidosis are early diagnosis, accurate typing, appropriate risk-adapted therapy, tight follow-up, and effective supportive treatment. The suppression of the amyloidogenic light chains using the cardiac biomarkers as guide to choose chemotherapy is still the mainstay of therapy. There are exciting possibilities ahead, including the study of oral proteasome inhibitors, antibodies directed at plasma cell clone, and finally antibodies attacking the amyloid deposits are entering the clinic, offering unprecedented opportunities for radically improving the care of this disease.

Abstract
There is limited information on the outcome when organs other than heart or kidneys are involved by immunoglobulin light-chain amyloidosis (AL). We report the outcome of 53 patients with AL with gastrointestinal (GI), peripheral nerve (PN), liver, lung, or soft-tissue involvement, who underwent high-dose chemotherapy and autologous hematopoietic stem cell transplantation (auto-HCT) at our institution between 1997 and 2013. The median age at auto-HCT was 56 years (range, 35 to 74). One, 2, 3, or 4 organs were involved in 43%, 22%, 28%, and 4% of patients, respectively. Concurrent cardiac, renal, or both were involved in 24 (45%) patients. Forty-six patients received induction therapy before auto-HCT. The 100-day and 1-year treatment-related mortality (TRM) were 3.8% (n = 2) and 7.5% (n = 4), respectively. Forty-one (80%) patients achieved a hematologic response. Organ response at 1 year after auto-HCT was seen in 23 (57%) of the 40 evaluable patients. With a median follow-up of 24 months, the median progression-free survival and overall survival (OS) were 36 and 73 months, respectively. Auto-HCT was associated with a low TRM, durable organ responses, and a median OS of > 6 years in selected patients with AL and GI, PN, liver, lung, or soft-tissue involvement.

Abstract
Immunoglobulin light chain amyloidosis (AL amyloidosis) has an incidence of approximately 1 case per 100,000 person-years in Western countries. The rarity of the condition not only poses a challenge for making a prompt diagnosis but also makes evidenced decision making about treatment even more challenging. Physicians caring for patients with AL amyloidosis have been borrowing and customizing the therapies used for patients with multiple myeloma with varying degrees of success. One of the biggest failings in the science of the treatment of AL amyloidosis is the paucity of prospective trials, especially phase 3 trials. Herein, we present an extensive review of the literature with an aim of making recommendations in the context of the best evidence and expert opinion.

Abstract
AL amyloidosis is the most common form of systemic amyloidosis and is associated with an underlying plasma cell dyscrasia. It is often difficult to recognize because of its many manifestations. Recent diagnostic and prognostic advances include the serum-free light chain assay, cardiac MRI, and serologic cardiac biomarkers. Treatment strategies that have evolved during the past decade are prolonging survival and preserving organ function. This article outlines the role of high-dose melphalan and stem cell transplantation. This year marks the 20th anniversary for the first patient who underwent successful stem cell transplantation for this disease at Boston Medical Center.

Abstract
Previous studies have suggested that, in patients with AL amyloidosis treated with high-dose melphalan and autologous stem-cell transplantation (HDM/SCT), the greatest benefit is seen in those patients achieving a hematologic complete response (CR). We analyzed a series of 421 consecutive patients treated with HDM/SCT at a single referral center and compared outcomes for patients with and without CR. Treatment-related mortality was 11.4% overall (5.6% in the last 5 years). By intention-to-treat analysis, the CR rate was 34% and the median event-free survival (EFS) and overall survival (OS) were 2.6 and 6.3 years, respectively. Eighty-one patients died within the first year after HDM/SCT and were not evaluable for hematologic and organ response. Of 340 evaluable patients, 43% achieved CR and 78% of them experienced an organ response. For CR patients, median EFS and OS were 8.3 and 13.2 years, respectively. Among the 195 patients who did not obtain CR, 52% achieved an organ response, and their median EFS and OS were 2 and 5.9 years, respectively. Thus, treatment of selected AL patients with HDM/SCT resulted in a high organ response rate and long OS, even for those patients who did not achieve CR.

Abstract
High-dose melphalan (MEL) with autologous stem cell transplant (SCT) is an effective therapy for systemic AL amyloidosis (AL), but treatment-related mortality (TRM) has historically been high. We performed a phase II trial of risk-adapted SCT followed by adjuvant dexamethasone (dex) and thalidomide (thal) in an attempt to reduce TRM and improve response rates. Patients (n = 45) with newly diagnosed AL involving < or =2 organ systems were assigned to MEL 100, 140, or 200 mg/m(2) with SCT, based on age, renal function and cardiac involvement. Patients with persistent clonal plasma cell disease 3 months post-SCT received 9 months of adjuvant thal/dex (or dex if there was a history of deep vein thrombosis or neuropathy). Organ involvement was kidney (67%), heart (24%), liver/GI (22%) and peripheral nervous system (18%), with 31% having two organs involved. TRM was 4.4%. Thirty-one patients began adjuvant therapy, with 16 (52%) completing 9 months of treatment and 13 (42%) achieving an improvement in haematological response. By intention-to-treat, overall haematological response rate was 71% (36% complete response), with 44% having organ responses. With a median follow-up of 31 months, 2-year survival was 84% (95% confidence interval: 73%, 94%). Risk-adapted SCT with adjuvant thal/dex is feasible and results in low TRM and high haematological and organ response rates in AL patients.

Abstract
BACKGROUND High-dose chemotherapy followed by autologous hematopoietic stem-cell transplantation has been reported to provide higher response rates and better overall survival than standard chemotherapy in immunoglobulin-light-chain (AL) amyloidosis, but these two strategies have not been compared in a randomized study. METHODS We conducted a randomized trial comparing high-dose intravenous melphalan followed by autologous hematopoietic stem-cell rescue with standard-dose melphalan plus high-dose dexamethasone in patients with AL amyloidosis. Patients (age range, 18 to 70 years) with newly diagnosed AL amyloidosis were randomly assigned to receive intravenous high-dose melphalan plus autologous stem cells or oral melphalan plus oral high-dose dexamethasone. RESULTS Fifty patients were enrolled in each group. The results were analyzed on an intention-to-treat basis, with overall survival as the primary end point. After a median follow-up of 3 years, the estimated median overall survival was 22.2 months in the group assigned to receive high-dose melphalan and 56.9 months in the group assigned to receive melphalan plus high-dose dexamethasone (P=0.04). Among patients with high-risk disease, overall survival was similar in the two groups. Among patients with low-risk disease, there was a nonsignificant difference between the two groups in overall survival at 3 years (58% in the group assigned to receive high-dose melphalan vs. 80% in the group assigned to receive melphalan plus high-dose dexamethasone; P=0.13). CONCLUSIONS The outcome of treatment of AL amyloidosis with high-dose melphalan plus autologous stem-cell rescue was not superior to the outcome with standard-dose melphalan plus dexamethasone.

Abstract
PURPOSE OF REVIEW High-dose chemotherapy increasingly is being used for the management of patients with immunoglobulin light-chain amyloidosis. We describe nearly 300 patients who had treatment combining high-dose chemotherapy and stem cell transplantation at Mayo Clinic and review the recent literature. RECENT FINDINGS We review outcomes, engraftment data, and predictors of early mortality. The survival benefit of transplantation, however, has not been verified in a phase III clinical trial. SUMMARY Partial response rates and complete response rates are prognosticators of survival for patients with amyloidosis. These rates are much higher for patients who receive high-dose therapy and transplantation.

Abstract
Amyloidosis is a rare disease in which amyloid fibrils compromise organ function and lead to death. Systemic immunoglobulin light-chain amyloidosis, usually caused by free light chains (FLCs) made by clonal plasma cells, is the most frequent type. Hereditary and senile systemic amyloidosis are less frequent types. Rarely, a patient with a tissue diagnosis of amyloidosis might have a monoclonal gammopathy and a hereditary protein. In systemic immunoglobulin light-chain amyloidosis, circulating clonal light chains can be measured with the FLC assay and provide a target for therapy aimed at eliminating the underlying plasma cell disorder while supporting the patient. Elimination of the pathologic FLC can lead to resorption of amyloid deposits and improvement in organ function. Monthly oral melphalan and dexamethasone for 1 year is effective therapy for patients not eligible for autologous stem cell transplantation (SCT) but carries a risk of myelodysplasia. For patients with limited organ involvement, SCT is an effective approach and, when followed after SCT by adjuvant thalidomide and dexamethasone for persistent plasma cell disease, achieves a high 1-year hematologic response rate. Complete hematologic responses can be durable beyond a decade and are usually associated with organ recovery. New agents, such as bortezomib and lenalidomide, have shown promising activity, and novel monoclonal antibody approaches are also under active investigation.

Abstract
Amyloidosis is a disease in which abnormal proteins form fibrillar tissue deposits that can compromise key viscera and lead to early death. In order to treat amyloidosis, the type of abnormal protein must be identified. The most common type is monoclonal immunoglobulin light chain or AL amyloidosis; the other important type is hereditary, caused by variant forms of transthyretin and other proteins, whereas amyloid associated with chronic inflammation ("secondary") is rare in the developed world. AL can be misdiagnosed if a monoclonal gammopathy and a hereditary variant are present in the same patient. The aim of therapy in systemic AL amyloidosis is to reduce the amyloid-forming monoclonal light chain, measured with the serum free light chain assay, by suppressing the underlying plasma cell dyscrasia, while using supportive measures to sustain organ function. Amyloid deposits can be resorbed and organ function restored if the amyloid-forming precursor light chain is eliminated. The most effective treatment for systemic AL amyloidosis is risk-adapted melphalan with peripheral blood stem cell transplant (SCT). The hematologic response rate is 75% at 12 months when adjuvant therapy with thalidomide and dexamethasone is used post-SCT. Patients can achieve long-term durable remissions with organ recovery. Drugs effective in multiple myeloma are usually helpful in AL amyloidosis if tolerated. The use of novel antibody-based approaches for imaging amyloid and possibly for accelerating removal of deposits is under active investigation.

Abstract
Light-chain (AL) amyloidosis is the most common form of systemic amyloidosis and is associated with an underlying plasma cell dyscrasia. The disease often is difficult to recognize because of its broad range of manifestations and what often are vague symptoms. The clinical syndromes at presentation include nephrotic-range proteinuria with or without renal dysfunction, hepatomegaly, congestive heart failure, and autonomic or sensory neuropathy. Recent diagnostic and prognostic advances include the serum free light-chain assay, cardiac magnetic resonance imaging, and serologic cardiac biomarkers. Treatment strategies that have evolved during the past decade are prolonging survival and preserving organ function in patients with this disease. This review outlines approaches to diagnosis, assessment of disease severity, and treatment of AL amyloidosis.

Abstract
High-dose chemotherapy with autologous stem cell transplantation (SCT) is widely used as a treatment for systemic AL amyloidosis, but its efficacy has not been proved and it has substantial toxicity in this setting. We report here the outcome of 92 patients evaluated at the UK National Amyloidosis Centre who underwent SCT for AL amyloidosis between 1994 and 2004 in various British centres. Median age was 53 years and median of two organs were affected by amyloidosis. All-cause day 100 mortality [treatment-related mortality (TRM)] was 23% for the entire cohort, although this was substantially greater for patients treated from 1994 to 1998 (15/47, 32%) than subsequently (6/45, 13%). Independent factors significantly associated with TRM on multivariate analysis were: number of affected organs, performance status, serum albumin and age. Response of the underlying clonal disease, defined by > or = 50% reduction in the aberrant serum-free light chain concentration, occurred in 83% of evaluable patients. Overall median survival was 5.3 years, and was 8.5 years among patients who survived beyond day 100. Despite recent refinements in patient selection, TRM remains substantial during SCT for systemic AL amyloidosis, and its place in the therapeutic armamentarium for this disease needs to be defined in randomised controlled clinical studies.

Abstract
OBJECTIVE To determine the outcome of high-dose therapy with autologous hematopoietic stem cell transplantation (HSCT) in patients with primary systemic amyloidosis reported to the Center for International Blood and Marrow Transplant Research (CIBMTR). PATIENTS AND METHODS A total of 107 recipients of autologous HSCT for amyloidosis from 48 transplantation centers were reported to the CIBMTR between 1995 and 2001. Hematologic and organ responses were assessed at 100 days and 1 year. Transplantation-related mortality (TRM) was assessed at day 30 after HSCT. A multivariate analysis assessed factors that influenced overall survival. RESULTS Improvement at day 100 was seen in 1 or more amyloidosis-affected sites (bone marrow, kidney, liver, and/or heart) in 28 (36%) of 77 patients; the 1-year responses included complete response (16%), partial response (16%), stable disease (31%), and disease progression (10%). With a median follow-up of 30 months, the 1- and 3-year survival rates were 66% (95% confidence interval [CI], 56%-75%) and 56% (95% CI, 45%-66%), respectively. The day 30 TRM was 18% (95% CI, 11%-26%). In the multivariate analysis, only the year of transplantation (patients who most recently underwent transplantation) was associated with post-HSCT survival (P-.02). CONCLUSION In this multi-institutional CIBMTR study, the 3-year survival rate was comparable to single-center results, with patients who more recently underwent transplantation faring better. Of note, the TRM was higher than that reported by single centers, which may reflect differences in patient selection and/or experience in treating this challenging disease. We hope that a better understanding of the recently recognized prognostic factors and more stringent patient selection will result in lower TRM and improved survival.

Abstract
The natural history of multiple myeloma (MM) was revolutionized by the introduction of haematopoietic stem cell transplantation to the treatment armamentarium of this disease. Defined subgroups of MM patients (such as the elderly or dialysis-dependent) have required an individualized approach in order to minimize the transplant-related mortality. Little, however, is known about the management of 12-30% of MM patients with coexistent AL amyloidosis as the amyloidopathy is often overlooked and when recognized these patients commonly are excluded from clinical trials. While occult amyloidosis appears to have no impact on the toxicity and outcome of MM patients, the presence of symptomatic amyloidopathy clearly worsens their prognosis. Use of induction chemotherapy drugs that can cause further damage to the heart (Adriamycin), nervous system (Vincristine) or kidneys should be avoided as should lengthy delays in proceeding to autograft. Further, refining the transplant eligibility criteria for this subgroup of patients with co-existent amyloidopathy to include the number of organs involved and the degree of cardiac involvement (NYHA class, Troponins and NT-pro-BNP levels) along with melphalan dose-adjustment will minimize the treatment-related toxicity and mortality and possibly allow a reversal of the organ damage induced by the amyloidogenic light chain.

Abstract
The spectrum of plasma cell disorders is broad. Monoclonal gammopathy of undetermined significance and smoldering multiple myeloma are asymptomatic disorders characterized by monoclonal plasma cell proliferation in the bone marrow in the absence of end-organ damage. Waldenström macroglobulinemia typically involves an ontogenically less mature lymphoplasmacytic bone marrow cell and is characterized by secretion of a monoclonal IgM protein. Solitary plasmacytoma is the only known potentially curable plasma cell disorder. Finally, AL (immunoglobulin light chain) amyloidosis and POEMS (polyneuropathy, organomegaly, endocrinopathy, monoclonal gammopathy, and skin changes) syndrome are disorders characterized by low tumor burden but profound multisystemic disease. Updated diagnostic criteria for these disorders, risk stratification models to determine prognosis, and the current management of these diverse entitles are discussed in this review.

Abstract
Systemic amyloid light chain amyloidosis is a protein conformation disorder caused by a clonal plasma cell dyscrasia. Symptoms result from fibrillar extracellular deposits in kidney, heart, liver, gut, peripheral nervous system and other tissues. The deposits disrupt organ function and ultimately lead to death. The prognosis of systemic amyloid light chain (AL) amyloidosis is poor; less than 5% of all patients survive 10 years or longer. Using conventional chemotherapy, the median survival could be prolonged by 4 months. Treatment with high-dose melphalm (HDM) and autologous stem cell transplantation (ASCT) of selected patients has been shown to arrest and even to reverse the disease course. This procedure however remains controversial because treatment related mortality (TRM) in AL amyloidosis is substantially higher (15-40%) than in multiple myeloma (<5%). Here we review recent results of ASCT, eligibility criteria for HDM and report our own treatment results in 41 patients.

Abstract
Recent reports from large amyloidosis referral centers suggest that primary systemic AL amyloidosis patients treated with high-dose melphalan (HDM) and autologous stem cell transplantation (ASCT) survive longer than historical controls treated with less intensive chemotherapy, despite high transplant-related mortality (TRM) rates of >10%. A retrospective review was conducted to determine if the outcome of ASCT for AL amyloidosis at our institution was similar to that reported at major amyloidosis referral centers. Over a 7 year period, we treated a total of 15 AL amyloidosis patients with ASCT, including four with poor prognosis cardiac or multisystem involvement. No TRM was observed. Overall, 10 patients (67%) achieved a complete hematological response and four patients (27%) achieved a complete organ response. The 4-year event-free and overall survival rates were 60% (95% CI 32-89%) and 75% (95% CI 50-100%), respectively. One patient, who presented with cardiac failure and multiorgan involvement with colonic bleeding currently remains in complete remission 62 months post-ASCT. In conclusion, ASCT for primary AL amyloidosis can safely be performed at experienced transplant centers that are not associated with major amyloidosis referral centers, and is feasible for patients who have multisystem involvement, particularly for motivated patients with good performance status.
