Objective: To evaluate the response of oral melphalan plus high-dose dexamethasone (MDex) for patients with primary light chain amyloidosis (pAL). Methods: Clinical data, hematological and organ responses, and survival of 76 patients with pAL who had received MDex from January 2009 to July 2017 were retrospectively analyzed. Results: Of 76 patients (47 males and 29 females with the median age of 56 [range, 20-74] years old), 19.70% patients were defined as Mayo 2004 stage 3, involvement of more than or two organs was presented in 65 (85.53%) patients. Among 60 response evaluable patients, overall hematological response was 48.33% with complete response of 20.00% and very good partial response of 20.00%, respectively. The median time to the hematological response was 5 (range, 1-15) months. 36.67% patients achieved organ response. After the median follow up of 23(range, 1-113) months for surviving patients, median progression-free survival (PFS) and overall survival (OS) were 34 and 43 months, respectively. In a three months landmark analysis, the median rates of PFS and OS were 46 and 65 months, respectively. The median OS rates of patients with Mayo 2004 stage 3 and non Mayo 2004 stage 3 were 5 and 65 months (P=0.001), respectively. Conclusions: MDex was an effective treatment for patients with early stage pAL, but was not suitable for those with severe cardiac involvement.

OBJECTIVETo observe the efficacy and side-effects of low-dose melphalan for the treatment of intermediate- to high-risk myelodysplastic syndromes (MDS) patients.

METHODSThirty patients with intermediate- to high-risk MDS received oral melphalan at a daily dose of 2 mg. The melphalan therapy was continued until marrow blasts increased or severe cytopenia attributed to melphalan. Patients achieved complete remission (CR) or partial remission (PR) were still maintained with melphalan until disease relapse.

RESULTSAmong the 30 patients, 9 (30.0%) achieved CR, 3 (10.0%) PR, 3 (10.0%) bone marrow complete remission and hematology improvement (MCR + HI), 1 (3.3%) MCR, 4 (13.3%) stable disease and 10 (33.3%) no response, the overall response rate being 66.7% according to the Modified International Working Group Response Criteria for MDS. The CR plus PR rate (60.0%) and total response rate (80.0%) in patients with normocellular or hypocellular bone marrow were significantly higher than in those with hypercellular bone marrow (0.0%, 40%, respectively) (P = 0.002 and 0.045, respectively). Median overall survival (OS) and median relapse-free survival (RFS) were 18 (95% CI 14-22) and 11 (95% CI 3-19) months, respectively. There was no side-effect except for slight marrow suppression in 3 patients and one patient died from brain hemorrhage on inefficacy of platelet transfusion.

CONCLUSIONSLow-dose melphalan therapy for intermediate- to high-risk MDS patients is safe and effective, especially suitable for elderly patients with hypocellular marrow.

OBJECTIVETo evaluate the efficacy and adverse effects of low dose thalidomide (TD) combined with modified VCMP (vincristine+cyclophosphamide+melphalan+prednisone) (TD+mVCMP) and VAD (vincristine+doxorubicin+dexamethsone) (TD+VAD) regimens for treating aged patients with MM.

METHODSA total of 47 patients with newly diagnosed MM were enrolled in this study. Among them 27 cases were treated with TD+mVCMP regimen (TD+mVCMP group), 20 cases were treated with TD+VAD regimen (TD+VAD group). The dose of TD in 2 groups all was 100 mg/d. Each patient received 4 or more courses of treatment.

RESULTSOut of 27 cases in TD+mVCMP group, 9 cases achieved complete remission (CR), 5 cases-very good partial remission (VGPR), 6 cases-partial remission (PR); among 20 cases in TD+VAD group, 3 cases achieved CR, 3 cases achieved VGPR, 4 cases achieved PR. The total effective rate in 2 group was 74.1% and 50% respectively, there was statistical difference between 2 groups (P<0.05). The differences of Hb level, plasmocytic ratio of bone marrow and M protein level in 2 groups before and after treatment were significant (P<0.05). The 5 years survival rate of patients in TD+mVCMP and TD+VAD group was 72.8% and 66.9% respectively, there was no statistical difference (P>0.05). The incidence of adverse reactions including caxdiac toxicity, severe leucopenia and thrombocytopenia in TD+mVCMP group was lower than that in TD+VAD group.

CONCLUSIONLow dose TD combined with modified VCMP regimen for treatment of newly diagnosed aged patients with MM is safe and effective, which may be used as the first line treatment regimen for population in aged MM patients.

While pleural effusion in multiple myeloma is relatively infrequent, myelomatous pleural effusion is extremely rare. We experienced a 61-year-old woman with IgD-lambda multiple myeloma and pleural effusion. The diagnosis was made originally by pleural biopsy, pleural fluid cytology and immunoelectropheresis of pleural fluid. Transient improvement of the pleural effusion was observed after administration of combination chemotherapy of vincristine, melphalan, cyclophosphamide, prednisone (VMCP)/vincristine, cyclophosphamide, adriamycin, prednisone (VCAP). Two months later, myelomatous pleural effusion recurred and no response to salvage therapy was observed. We reviewed the clinical feature of this case and literature concerning myelomatous pleural effusion.

Impaired tumor necrosis factor receptor-1 (TNFR-1) signaling has been found in some malignant tumors with poor prognosis. However, the exact role of TNFR-1 signaling in fibrosarcoma remains unclear. Here, we explored the question by comparing the growth of TNFR-1 deficient (Tnfr1 (-)) and TNFR-1 competent (Tnfr1 (+)) fibrosarcoma FB61 cells (FB61-m and FB61-R1) in mice. TNFR-1 expression on fibrosarcoma cells delayed their growth in vivo but not in vitro. Moreover, reduced FB61-R1 tumor growth was also obtained in TNFR-1 knockout mice. The mechanism relies mainly on the TNFR-1-mediated downregulation of vascular endothelial growth factor (VEGF) production by tumor cells. Importantly, treatment of FB61-m tumors with melphalan resulted in a short delay of tumor growth, followed by a quick remission. However, when FB61-R1 tumors were treated with melphalan, tumor growth was similarly delayed at first and then completely rejected. Our results reveal evidence for TNFR-1 on tumor cells as a prerequisite in chemotherapy for fibrosarcoma, and provide novel insight into the therapeutic approach against some types of tumors using TNFR-1 angonist.

BACKGROUND: The long-term survival of patients with non-Hodgkin's lymphoma after conventional chemotherapy is about 35%, with the remaining 65% of patients tending to be refractory or experience relapse. As such, primary refractory patients responding to salvage chemotherapy, and sensitive relapsed patients and primary high- risk patients are recommended to receive high-dose chemotherapy (HDC) and autologous peripheral blood stem cell transplantation (PBSCT). We evaluated the role of HDC and autologous PBSCT in patients with primary refractory, primary high risk, and sensitive relapsed non-Hodgkin's lymphoma. METHODS: We performed a retrospective analysis of the data from 50 patients with non-Hodgkin's lymphoma who were treated with HDC and autologous PBSCT in the Catholic Hematopoietic Stem Cell Transplantation Center between 1997 and 2002. RESULTS: Of the 50 patients, the conditioning regimen was BEAM in 20, CMT (cyclophosphamide, melphalan and thiotepa) in 19, fludarabine- and total body irradiation (TBI) -based regimen in 8, and cyclophosphamide and TBI in 2. There were 3 (6%) deaths due to treatment-related toxicity within the first 50 days after transplantation. Twenty-five patients remain alive at a median follow-up duration of 40.5 months (range 9~61). Among the patients with partial response before transplantation, 76% showed further response after transplantation. In half of these responders, the disease state was changed into complete response (CR) after transplantation. 2-year overall survival was 52% and 2-year progression free survival was 36.8%. Median overall survival was 34 months (range 8~60), and median progression-free survival was 8 months (range 1~14). Median overall survival was 14 months (range 9~19) in the primary high-risk group (n=13), 7 months (range 4~10) in the resistance relapse group (n=5), and 6 months (range 0~14) in the primary refractory group (n=10). Overall survival in the sensitive relapse group (n=22) did not reach the median; the mean overall survival in this group was 33 months. The disease status before transplantation was the only significant prognostic factor in determining overall survival (p=0.032) and progression- free survival (p=0.001). CONCLUSION: HDC and autologous PBSCT appears to produce high response rate. Primary high-risk group and sensitive relapse group had good prognosis, while refractory and resistance relapse group had poor prognosis. And the pre-transplantation disease status was the only significant prognostic factor in multivariate analysis.

OBJECTIVETo investigate the safety of treatment with ophthalmic artery cannulation for intra-arterial chemotherapy (IAC) for children with intraocular retinoblastoma (RB).

METHODIn the RB Treatment Center of General Hospital of Armed Police Forces between January 2009 and September 2011, 42 patients who were diagnosed intraocular RB and treated with ophthalmic artery cannulation for IAC, 8 patients were treated 1 circle, 31 patients were treated 2 circles and 3 patients were treated 3 circles (total, 96 times). Each month had IAC once. The ophthalmic and the whole body evaluations were performed during IAC and after IAC for each circle, the blood cell count, alanine aminotransferase (ALT), serum creatinine (Scr), CK-MB content before and after IAC for 1 circle, 2 circles and 3 circles were determined.

RESULT(1) In 52 eyes of 42 patients, 44 eyes (84.6%) were in remission. (2) Successful IAC was achieved in all cases, no severe side effects occurred during IAC. (3) The main ophthalmic complications were eyelid edema and blepharoptosis after IAC, the incidence for 1 circle was 18% (2/11) and 9% (1/11); for 2 circles was 29% (11/38) and 21% (8/38); for 3 circles was all 100% (3/3). The rare complications were vitreous hemorrhage and heterotropia, the incidence was all 2% (1/42). The incidence of eyelid edema and blepharoptosis had no significant differences for 1 circle IAC compared with 2 circles (P > 0.05); the incidence of eyelid edema and blepharoptosis had significant differences for 3 circles IAC compared with 2 circles and 1 circle (P < 0.01). (4) No fever, septicemia and other systemic toxic effects occurred. (5) ALT of 19% patients (8/42) elevated temporarily and CK-MB of 24% patients (10/42) increased. The blood cell counts, ALT, Scr, and CK-MB content before IAC had no significant differences compared with that at 24 h after IAC for 1 circle, 2 circles and 3 circles (P > 0.05).

CONCLUSIONOphthalmic artery cannulation for IAC is a safe and effective method in treating intraocular stage retinoblastoma.
