Abstract Aim and Background: Renal impairment (RI) is common feature in patients with multiple myeloma (MM) and is considered as a poor prognostic factor. Improvement of renal function can lead to the improved survival in patients with MM, however little is known on the prognostic impact of reversal of RI compared to that of the patients without RI at diagnosis in the novel agent era. To address this issue, we retrospectively analyzed the impact of RI on survival of newly diagnosed multiple myeloma (NDMM) patients with or without RI seen at our Department over the past 15 years. Patients and Methods: The study population included all patients diagnosed as MM and treated during May 2000 to March 2015 at Kameda Medical Center, Kamogawa-shi, Japan. We reviewed and retrospectively analyzed the medical records of the Department of Hematology/Oncology. All statistical analyses were performed with EZR, which is a graphical user interface for R ver. 3.2.1. Results: We identified 258 patients with NDMM during this period. RI was defined as eGFR<50ml/min/1.73m2. The median age of patients at diagnosis was 72 years (range 42-90), and 144 patients (55.6%) were male. The median follow-up period for the entire group was 37 months, median serum creatinine at diagnosis was 2.01mg/dL (range 0.4-15) and median eGFR was 52.4ml/min/1.73m2 (range: 2.11-136). RI was observed 122 patients (47.2%). Median serum creatinine of patients with and without RI at diagnosis was 2.07 mg/dL (range: 0.80-4.2) and 0.75mg/mL (range: 0.4-1.1), respectively (p<0.001). Patients with RI had significantly higher proportion of light-chain only disease (39.3% vs 12.5%, p<0.001), International Staging System (ISS) stage 3 (76.2%, vs 31.6%, p=0.001), and lower hemoglobin concentration (Hb<8.5mg/dL: 44.2% vs 21.3%, p<0.001). Bortezomib use, high risk cytogenetics, sex, serum LDH, age at diagnosis, amount of involved immunoglobulin, light chain subtype, and urine albumin at diagnosis were not different between patients with and without RI. Median overall survival (OS) for patients with (n=122) and without (n= 136) RI were 39 months and 57 months, respectively (p=0.16). The median OS for patients with or without RI before and after December 2006, when bortezomib became available in Japan, were 28 months and 41 months (p= 0.66), and 46 months and 71 months (p=0.01), respectively. To evaluate the prognostic impact of renal improvement on survival, patients were divided into 3 groups according to the eGFR and subsequent renal response: Group A; eGFR ≥ 50ml/min/1.73m2 at diagnosis, Group B; eGFR < 50 ml/min/1.73m2 at diagnosis but improved to >50ml/min/1.73m2, Group C; eGFR < 50 ml/min/1.73m2 at diagnosis, and remained <50 ml/min/1.73m2. Median OS of patients with Group A, B, and C was 57 months (n=136), 41 months (n=73), and 25 months (n=49), respectively (p=0.02) (Figure 1). When patients were analysed before and after 2006, the median OS of patients with group A, B, and C before 2006 were 41months (n=59), 38months (n=25) and 19months (n=15) (p=0.02), and those of after 2006 were 71 months (n=77), 46 months (n=48) and not reached (n=34) (p=0.03), respectively. On landmark analysis, median OS at 6 months in each group (Group A, B, and C) were 66 months (n=122), 43 months (n=42), 62 months (n=54), respectively (p= 0.74). Early mortality rate (within 6 months from diagnosis) was significantly higher in patients with group C (16%) compared to other groups (8.5% for group A and 8% for group B, respectively, p=0.03). Patients with group C has significantly higher proportion of mortality rate of infectious disease (26.9%) compared to other groups (7.6% for group A and 11.5% for group B, respectively, p=0.04). Reversal of RI was associated with free light chain (FLC) reduction rate >95% at day 21, age<70years, and treatment response ≥VGPR on univariate analysis, but only FLC reduction rate>95% at day 21 retained its significance on multivariate analysis Conclusions: Patients with MM with RI showed poor prognosis compared to those without RI. FLC reduction > 95% at day 21 was the independent prognostic predictor for reversal of RI. The higher mortality rate within 6 month of diagnosis observed in patients with RI without renal recovery might attribute to the inferior survival in patients with RI. Although patients with RI with improved renal function had superior survival compared to those without, it remains inferior to the patients without RI at diagnosis Figure 1. mOS of group A, B, and C Figure 1. mOS of group A, B, and C Disclosures No relevant conflicts of interest to declare.

Abstract Abstract 955 Renal impairment (RI) is a common complication of multiple myeloma (MM) and is associated with increased mortality. High dose dexamethasone-based regimens have been extensively used for the initial management of patients with MM presenting with RI. Recently, novel agent-based regimens have been introduced in the frontline management of MM. The purpose of our analysis was to assess the effect of novel agent-based regimens on the rate of RI improvement and compare their efficacy with conventional chemotherapy (CC) plus dexamethasone (Dexa) in newly diagnosed MM patients. Over the last decade, 82 patients with newly diagnosed MM and RI, defined as creatinine clearance (CrCI) <50ml/min, received frontline treatment in our Center. Patients were divided into three groups: group A: 28 patients who received CC plus Dexa-based regimens (VAD, VAD-like regimens, melphalan plus Dexa); group B: 38 patients who received IMiDs-based regimens (thalidomide or lenalidomide with high dose Dexa and/or cyclophosphamide or melphalan) and group C: 16 patients who received bortezomib-based regimens with Dexa. Renal complete response (RCR) was defined as a sustained increase of baseline CrCI to >60ml/min. Renal partial response (RPR) was defined as an increase of CrCI from<15 to 30-50ml/min. Renal minor response (RMR) was defined as sustained improvement of baseline CrCI of<15ml/min to 15-29 ml/min, or, if baseline CrCI was 15-29 ml/min, improvement to 30-59 ml/min. Patients in group B were older than those of groups A and C (p=0.01) while more patient in group C had light chain only MM than in groups A and B (p=0.04). There were no significant differences in the severity of RI, Bence Jones proteinuria, hypercalcemia or ISS stage among the three groups. Improvement of renal function, recorded as RMR or better, was achieved more frequently in patients treated with novel agents (group B: 87% and in group C: 94%) than in patients treated with CC plus Dexa-based regimens (64%, p=0.024). Among 9 patients who required renal dialysis 3 became independent of this procedure after treatment. We subsequently focused our analysis in major renal responses (RPR or RCR), because this endpoint is clinically more relevant. RCR was achieved in 43% of patients in group A, in 50% in group B and in 69% of patients in group C (p=0.2) and RCR+RPR rates were 50% and 57% and 81% for groups A, B and C respectively (p=0.1). Creatinine clearance <30 ml/min was associated with a significantly lower probability of RCR or RPR only in patients treated with CC plus Dexa- or with IMiDs-based regimens (p<0.01), but not in patients treated with bortezomib (p=0.529). The probability of RPR+RCR was similar for patients treated with IMiDs compared to CC plus Dexa-based regimens (p=0.619). In multivariate analysis bortezomib–based regimens (p=0.02, OR: 7, 95% CI 1.5-25) and CrCl>30 ml/min (p=0.002, OR: 6.1, 95% CI 2.5-22.5) were independently associated with a higher probability of RCR+RPR. The median time to RPR was similar for patients treated with IMiDs compared to CC plus Dexa-based regimens (2.2 months for Group A, 1.5 months for Group B, p=0.587) but it was significantly shorter for Group C (0.7 months, p=0.017). Other factors associated with a shorter time to ≥RPR included CrCl>30 ml/min (p=0.039) and age<75 (p=0.089). In multivariate analysis bortezomib–based regimens (p=0.004, OR: 3 95% CI 1.6-6.7) and CrCl>30 ml/min (p=0.006, OR: 2.5 95% CI 1.3-4.5) were independently associated with a shorter time to ≥RPR. In landmark analysis (time was one month in order to reduce bias due to early deaths), rapid improvement of renal function (≤1 month) was associated with a trend for a longer survival compared to patients who achieved renal response later (>1 month) (47 vs. 21 months, p=0.19). Myeloma response to treatment was 58%, 68% and 79% for the three treatment groups respectively and was associated with renal response (p=0.024), though less strongly with a major renal response (p=0.061). Our data indicate that novel agent-based regimens can improve renal function in most patients; furthermore bortezomib-based regimens improve renal function to a higher degree and significantly more rapidly than CC plus Dexa-based or IMiD-based regimens even in patients with severe renal impairment. We conclude that bortezomib-based regimens may be the preferred treatment for newly diagnosed myeloma patients who present with renal impairment.

Abstract Introduction Serious renal failure represents a main complication of Multiple Myeloma (MM). An estimated 25% to 50% of patients are affected during the course of their disease. These patients are at increased risk for infections and have a significantly worse prognosis. Small phase I/II studies suggest that treatment with chemotherapy and/or new substances results in recovery of renal function in more than 25%. The window of opportunity for reversal of renal impairment is rather small making an immediate and highly active treatment strategy mandatory. Bortezomib and bendamustine have turned out to be quickly acting and effective drugs in the treatment of MM. Methods Between March 2005 and March 2013, 36 patients (median age 64; range 32-81 years) with relapsed/refractory MM and light chain induced renal failure (creatinine clearance <60ml/min) were treated with bendamustine 60mg/qm on day 1 and 2, bortezomib 1.3mg/qm on day 1, 4, 8 and 11, and prednisone 100mg on day 1, 2, 4, 8 and 11. Cycles were repeated every 21 days. Patients were divided into two groups: group A (n=20) consisted of patients with moderate or severe renal dysfunction (eGFR 15-59ml/min) and group B (n=16) of patients with renal failure/dialysis (eGFR <15ml/min). Results The median number of the BPV-treatment was 2 (1-7) cycles. 24 patients (67%) responded after at least one cycle of chemotherapy with 3 CR, 3 nCR, 6 VGPR, and 12 PR. Six patients had MR, 2 patients stable disease and 4 patients had a progress. With a median follow up of 22 months of the surviving patients, median PFS and OS for patients with moderate or severe renal dysfunction (group A) were 10 months and 25 months, respectively. Outcome for these patients was significantly better compared to patients with renal failure/dialysis (group B) with a median PFS and OS of 3 months and 7 months, respectively (p<0.02). Eleven patients showed a CRrenal, 5 patients a PRrenal and 15 patients a MRrenal. Median time to first renal response and best renal response were 21 days and 42 days, respectively. The most common severe side effect was grade 3-4 thrombocytopenia in 81% of the patients. Grade 3-4 neutropenia was observed in 50% of the patients. Moderate to severe infections were seen in 13 patients. Summary These results indicate that the combination of bortezomib, bendamustine and prednisone is effective and well tolerated in patients with relapsed/refractory MM and light chain induced renal failure. Disclosures: No relevant conflicts of interest to declare.

Abstract Introduction: Lenalidomide (Len) and dexamethasone (dex) has proven to be a highly effective treatment for multiple myeloma (MM) and serves as the basis of other combinations in relapsed disease. However, nearly 1/3 of myeloma patients have renal insufficiency, and the optimal use of Len in this population is not well known. We undertook this study in 3 cohorts of pts: Group A had creatinine clearance (CrCl) of 30-60 ml/min, Group B with CrCl < 30 ml/min, and Group C, with CrCl < 30 ml/min and requiring dialysis. The Phase I component of the trial has been previously reported (ASCO 2014) demonstrating that full dose Len (25mg daily 21/28 days) can be given to all patients despite renal insufficiency, even when on dialysis. We now present data on response to treatment. Methods: In the Phase 2 component accrual was slow and the trial was terminated. However, prior to termination a modified exploratory analysis plan was established, including all 34 patients treated at the recommended phase 2 dose. This plan would declare the treatment worthy of further study if 18 or more of the 34 patients responded to treatment. This design had 84% power to distinguish a response rate of 60% from a null rate of 40%, using a 1-sided test with 10% type I error. Results: The Phase 2 efficacy cohort accrued 34 patients, consisting of 20 patients from Group A, 9 patients from Group B, and 5 patients from Group C. Response of PR or greater was seen in 17 patients, resulting in a 50% overall response rate (CI 37-63%). Treatment was well tolerated with expected adverse events; the most common adverse events were anemia, diarrhea, and fatigue. Eleven episodes of Grade 3 and one Grade 4 pneumonia were reported for 10 patients across all cohorts and dose levels; 3 were considered possibly related to treatment. Seventeen patients have remained on treatment for more than 12 cycles. In the exploratory analyses, median PFS was 7.5 months (95% CI, 3.6 - 19.7 months) and median OS was 19.7 months (95% CI, 10.4 - 42.5 months). Conclusions: Len Dex can be safely administered to patients with impaired renal function at full dose of 25mg daily 21/28 days, and is associated with a 50% response rate. Further investigation into other combinations with Len Dex in patients with renal impairment should be considered. Table Table.

Abstract Multiple myeloma (MM) remains an incurable disease, with significant variation in the response and survival even with current treatment modalities, such as high-dose chemotherapy (CTx) and autologous stem cell transplantation (auto-SCT), novel drugs and intensive supportives. Hence, prognostic parameters that help to predict the benefit of different therapeutics are of utmost importance to be defined further. The objective of this analysis was to determine whether treatment selection and response are markedly influenced by specific clinico-pathological parameters and how these effect overall survival (OS). Of 143 consecutive MM patients (pts) receiving either standard therapy (Std-CTx, group A, n=79) or auto-SCT (group B, n=64) at our center between 1997–2003, gender, age, MM-type, -stage, number of CTx lines, LDH,β 2-MG and bone marrow (BM) infiltration were evaluated on response and survival in uni- and multivariate analyses and hazard ratios (HR) were determined. To further pay tribute to pts’ average age, as MM is primarily a disease of the elderly, special attention was paid to the influence of the performance status (Karnofsky Index=KI) and number of concurrent diagnoses (CD). Pts in groups A and B were comparable in terms of gender distribution, MM type, CD and LDH-level. However, group A as compared to B pts were older (65 vs. 56 yrs), had received more radiation (26 vs. 19%) and showed higher β2-MG (5 vs. 2.3g/L; respectively). Moreover, pts in group B as compared to A had more advanced disease (Durie and Salmon [D&S] stage II/III: 92 vs. 65%), a higher BM-infiltration (40 vs. 30%), and were treated later in their disease course. In group A pts, HR were increased for β2-MG>3, D&S stage II/III, stage B disease, CD>1, LDH>200U/L and age >60y, and HR decreased for females and KI>80%, reaching significance for β2-MG, D&S stage II/III, stage B disease, CD and KI. Although these HR were also observed for group B pts, none of these prognostic factors reached statistical significance. Multivariate analysis on all pts identified β2-MG >3mg/L and age >60y as independent prognostic factors, with HRs of 3.6 (95% CI 1.6–8.1) and 2.1 (CI 0.9–5.0), respectively. Of note, current CR/PR rates for group A and B pts are 4 vs. 20%, and at last follow-up (6/2006) median OS from treatment initiation is 49.5% vs. 61.4%, respectively. Our data show that an elevated β2-MG, D&S stage II/III, stage B disease, more than 1 CD and reduced performance status before therapy, negatively influence response and OS in Std-group pts, whereas these do not significantly impact HR in auto-SCT pts. We conclude that MM pts benefit from auto-SCT independently of prognostic factors which, however, do impact outcome with Std-CTx alone. Since randomized trials have repetitively shown response and survival with auto-SCT to be superior to Std-CTx, we propose that pts with the above prognostic factors should be carefully evaluated for intensive therapies, as this analysis accentuates that auto-SCT is the treatment of choice for eligible MM pts.

Objective To explore the effects of continuous renal replacement therapy (CRRT) on renal function and toxin clearance in patients with sepsis and concurrent acute kidney injury (AKI). Method A retrospective analysis was performed using the medical records of 115 patients with sepsis and AKI. Among them, 60 patients received routine treatment (group A) and 55 patients received CRRT plus routine treatment (group B). Result After treatment, the clearance rates of serum creatinine, lactic acid, and urea nitrogen were significantly lower in group A than in group B. The decrease in high-sensitivity C-reactive protein and tumor necrosis factor-α levels after treatment was significantly higher in group B than in group A. For the Acute Physiology Chronic Health Evaluation (APACHE) II and Sequential Organ Failure Assessment (SOFA) scores from the two groups, the scores were significantly lower in group B than in group A. The mortality rate within 28 days was significantly higher in group A than in group B. Conclusion CRRT can effectively improve the condition of patients with sepsis and AKI, promote elimination of toxins (serum creatinine, lactic acid, and urea nitrogen) from the body, and reduce the mortality rate.

Abstract Abstract 1869 Backgrounds & Aims: More intensive and novel therapy options in multiple myeloma (MM) improve the treatment outcome. However, disease evolution, induced with long disease duration and extensive pretreatment, has resulted in changes in the biological behavior of MM and unusual relapse emergence. Therefore, we studied the relapse pattern after bortezomib based salvage treatment in patients with MM and also we analyzed the prognostic significance according to relapse pattern. Methods: We have retrospectively analyzed the relapse pattern. Eligibility criteria included primary refractory or relapsed MM patients who must have received previous chemotherapy and they also received at least 2 cycles of bortezomib based salvage treatment. Immunoglobulin M type of MM, primary amyloidosis and plasma cell leukemia were excluded in this study. For evaluation of disease response, International Myeloma Working Group (IMWG) uniform response criteria were used. Results: Between November 2004 and August 2011, 132 patients received bortezomib based salvage chemotherapy. In 132 patients, 91 (68.9%) patients showed the disease relapse. The pattern of relapse after bortezomib salvage treatment was heterogeneous, the 14/91 (15.4%) patients relapsed as a novel manifestation comparison with the initiation of bortezomib (plasmacytoma: 7 patients, light chain escape pattern: 4 patients and, plasma cell leukemia: 2 patients). There was no statistical difference in the duration from diagnosis to bortezomib treatment according to novel (group A) vs isoform (group B) relapse. In the group B, the median overall survival after relapse was 16.1 months (95% CI: 11.4–20.8) and the group A was 2.5 months (95% CI: 0.0–5.7)(p=0.000). The 27 out of 132 patients received the retreatment of bortezomib and 23 out of 27 patients showed the disease progression. The 4/24 (16.7%) patients relapsed as a novel manifestation (plasmacytoma: 2 patients, light chain escape pattern: 1 patients and intact immunoglobulin secretion from plasmacytoma type: 1 patient). In patients received retreatment of bortezomib, novel relapsed group showed the trend of poor survival without statistical significance (2.2 months vs 10.0 months) (p=0.30). Conclusion: Our report suggests that bortezomib treatment contribute as a selective pressure and it has culminated in novel relapse manifestation. The relapsed patients as novel pattern after bortezomib treatment show the extreme poor prognosis. These findings suggest that these patients may be worth consideration for intensive treatment or early clinical trials. Disclosures: No relevant conflicts of interest to declare.

This study involved the collection of (90) samples of women serum which included (30) serum samples collected from women before menopause (reproductive women) in the age range of (22-43) years and were considered as (group A- control). While, (group B) included (30) serum samples collected from women using oral contraceptive pills between the ages of (22-43) years old. Whereas, another (30) serum samples were collected from women after menopause between the ages of (43-54) years and were considered as (group C). All of the collected serum samples were subjected to a number of serological and chemical tests for the measurement of (E2, HDL, LDL and Ca). Then, the obtained data were statistical analyzed and results showed a significant decrease (p˂ 0.05) in (E2 ,Ca and HDL) levels in menopausal women compared to that of the normal healthy controls. While, there were non-significant decrease (p> 0.05) in (E2, Ca and HDL) levels in women taking oral contraceptive when compared to the normal healthy controls. On the other hand, a significant increase (p˂ 0.05) was recorded in LDL level in menopausal women compared to that of the normal healthy controls whereas, no-significant increase (p˃ 0.05) in the LDL level in women taking oral contraceptives when compared to the control women.

Shweta Pradara (Leucorrhoea) is the disease which is characterized by vaginal white discharge. Vaginal white discharge this symptom is present in both physiological and pathological condition, when it becomes pathological it disturbs routine life style of the woman. Most of the women in the early stage will not express the symptoms because of hesitation and their busy schedule. If it is not treated it may leads to chronic diseases like PID (Garbhashaya Shotha etc.) Charaka mentioned Amalaki Choorna along with Madhu and Vata Twak Kashaya Yoni Pichu Dharana. This treatment is used in Shweta Pradara shown positive results, hence a study was under taken to assess its clinical efficacy. 30 diagnosed patients of Shweta Pradara were randomly selected, allocated in three groups. Group A and Group B received Amalaki Choorna with Madhu and Vata Twak Kashaya Yoni Pichu Dharana respectively and Group C received Amalaki Choorna with Madhu followed by Vata Twak Kashaya Yoni Pichu Dharana for 15 days. The patients were assessed for the severity of the symptoms subjectively and objectively before and after the treatment and at the end of the follow up. Data from each group were statistically analyzed and were compared. No side effects were noted and it may be considered as an effective alternative medicine in Shweta Pradara (leucorrhea). Amalaki is rich in natural source of vitamin C and contains phosphorus, iron and calcium. Honey contains carbohydrate, vitamin C, phosphorus iron and calcium. All together these help to increase Hb% and immunity. Vata Twak Kashaya contains tannin which helps to maintain normal pH of the vagina.

Background: Studies have shown that aggressive treatment of non-small cell lung cancer (NSCLC) with oligometastatic disease improves the overall survival (OS) compared to a palliative approach and some immunotherapy checkpoint inhibitors, such as anti-programmed cell death ligand 1 (PD-L1), anti-programmed cell death protein 1 (PD-1), and T-Lymphocyte-associated antigen 4 (CTLA-4) inhibitors are now part of the standard of care for advanced NSCLC. However, the prognostic impact of PD-L1 expression in the oligometastatic setting remains unknown. Methods: Patients with oligometastatic NSCLC were identified from the patient database of the Centre hospitalier de l’Université de Montréal (CHUM). “Oligometastatic disease” definition chosen is one synchronous metastasis based on the M1b staging of the eight IASLC (The International Association for the Study of Lung Cancer) Classification (within sixth months of diagnosis) or up to three cerebral metastasis based on the methodology of the previous major phase II randomized study of Gomez et al. We compared the OS between patients receiving aggressive treatment at both metastatic and primary sites (Group A) and patients receiving non-aggressive treatment (Group B). Subgroup analysis was performed using tumor PD-L1 expression. Results: Among 643 metastatic NSCLC patients, we identified 67 patients with oligometastasis (10%). Median follow-up was 13.3 months. Twenty-nine patients (43%) received radical treatment at metastatic and primary sites (Group A), and 38 patients (57%) received non-aggressive treatment (Group B). The median OS (mOS) of Group A was significantly longer than for Group B (26 months vs. 5 months, p = 0.0001). Median progression-free survival (mPFS) of Group A was superior than Group B (17.5 months vs. 3.4 months, p = 0.0001). This difference was still significant when controlled for primary tumor staging: stage I (p = 0.316), stage II (p = 0.024), and stage III (p = 0.001). In the cohort of patients who were not treated with PD-L1 inhibitors, PD-L1 expression negatively correlated with mOS. Conclusions: Aggressive treatments of oligometastatic NSCLC significantly improve mOS and mPFS compared to a more palliative approach. PD-L1 expression is a negative prognostic factor which suggests a possible role for immunotherapy in this setting.

Abstract Background Standardized training allows more physicians to master otoendoscopic surgery. However, the lecture-based learning (LBL) applied in otoendoscopy teaching may not be conducive to training students in clinical thinking and surgical ability. It is necessary to explore innovative methods for otoendoscopy teaching. This study aimed to determine the effect of a step-by-step (SBS) method combined with case-based learning (CBL) in otoendoscopy teaching. Methods Fifty-nine physicians who participated in otoendoscopy training were selected as the study subjects and randomly divided into two groups (A and B). Group A underwent training with the SBS & CBL method, while Group B underwent training with the LBL & CBL method. The effects of these two methods for otoendoscopy training were compared by evaluation of professional skills and questionnaires before and after the training. Results Proficiency in otoendoscopic anatomy and grades for both professional knowledge and otoendoscopic skills were significantly higher in Group A than in Group B(P < 0.05). In terms of learning interest, surgical ability, acting capacity during surgery, reducing surgical complications, and satisfaction with learning experience, all responses from Group A were better than those from Group B(P < 0.05). Conclusions The SBS & CBL method may help to improve ability in otoendoscopic surgery and clinical thinking and appears suitable for endoscopy teaching.
