PURPOSE To assess the efficacy, toxicity, and applicability of high-dose therapy administered as adjuvant initial treatment to women with breast cancer with extensive nodal involvement. PATIENTS AND METHODS Sixty-seven patients with stage II to III breast cancer involving > or = 10 axillary nodes received a novel high-dose sequential (HDS) regimen, including the high-dose administration of three non-cross-resistant drugs (cyclophosphamide, methotrexate, and melphalan) given within the shortest interval of time as possible with hematologic and nonhematologic toxicity. RESULTS Sixty-three patients completed the program as planned, one patient died of acute toxicity, and three patients were switched to standard-dose adjuvant therapy. After a median follow-up duration of 48.5 months and a lead follow-up of 78 months, actuarial relapse-free survival for all 67 registered patients is 57% and overall survival is 70%, respectively. Comparison with a historical control group of 58 consecutive patients showed a significantly superior rate of freedom from relapse for the HDS-treated group (57% v 41%, respectively), in particular when two subgroups of patients, more homogeneous for their number of involved nodes, were compared (65% v 42%). Overall, treatment was of short duration (median, 70 days), required a median of 32 days of hospital stay, and was associated with only a few severe side effects (the most distressing being oral mucositis after melphalan therapy). CONCLUSION HDS therapy emerges as an effective and applicable regimen, whose major toxicity was occasional. Final assessment of its value in a randomized, multicenter trial is presently underway.

PURPOSE We studied high-dose cyclophosphamide, cisplatin, and carmustine (CPA/cDDP/BCNU) with autologous bone marrow support (ABMS) as consolidation after standard-dose adjuvant chemotherapy treatment of primary breast cancer involving 10 or more axillary lymph nodes. PATIENTS AND METHODS One hundred two women with stage IIA, IIB, IIIA, or IIIB breast cancer involving 10 or more lymph nodes at surgery were registered; 85 were eligible, treated, and assessable. Patients were treated with four cycles of standard-dose cyclophosphamide, doxorubicin, and fluorouracil (CAF), followed by high-dose CPA/cDDP/BCNU with ABMS. RESULTS Actuarial event-free survival for the study patients at a median follow-up of 2.5 years is 72% (95% confidence interval, 56% to 82%). Comparison to three historical or concurrent Cancer and Leukemia Group B (CALGB) adjuvant chemotherapy trials selected for similar patients showed event-free survival at 2.5 years to be between 38% and 52%. Therapy-related mortality was 12%; pulmonary toxicity of variable severity occurred in 31% of patients. Quality-of-life evaluations indicate that patients are functioning well without major impairments. CONCLUSION High-dose consolidation with CPA/cDDP/BCNU and ABMS after standard-dose CAF results in a decreased frequency of relapse in patients with high-risk primary breast cancer compared with historical series at the median follow-up of 2.5 years. Evaluation in a prospective, randomized trial is warranted and currently underway.

Abstract Background The preservation or restoration of β cell function in type 1 diabetes (T1D) remains as an attractive and challengeable therapeutic target. Mesenchymal stromal cells (MSCs) are multipotent cells with high capacity of immunoregulation, which emerged as a promising cell-based therapy for many immune disorders. The objective of this study was to examine the efficacy and safety of one repeated transplantation of allogeneic MSCs in individuals with T1D. Methods This was a nonrandomized, open-label, parallel-armed prospective study. MSCs were isolated from umbilical cord (UC) of healthy donors. Fifty-three participants including 33 adult-onset (≥ 18 years) and 20 juvenile-onset T1D were enrolled. Twenty-seven subjects (MSC-treated group) received an initial systemic infusion of allogeneic UC-MSCs, followed by a repeat course at 3 months, whereas the control group (n = 26) only received standard care based on intensive insulin therapy. Data at 1-year follow-up was reported in this study. The primary endpoint was clinical remission defined as a 10% increase from baseline in the level of fasting and/or postprandial C-peptide. The secondary endpoints included side effects, serum levels of HbA1c, changes in fasting and postprandial C-peptide, and daily insulin doses. Results After 1-year follow-up, 40.7% subjects in MSC-treated group achieved the primary endpoint, significantly higher than that in the control arm. Three subjects in MSC-treated group, in contrast to none in control group, achieved insulin independence and maintained insulin free for 3 to 12 months. Among the adult-onset T1D, the percent change of postprandial C-peptide was significantly increased in MSC-treated group than in the control group. However, changes in fasting or postprandial C-peptide were not significantly different between groups among the juvenile-onset T1D. Multivariable logistic regression assay indicated that lower fasting C-peptide and higher dose of UC-MSC correlated with achievement of clinical remission after transplantation. No severe side effects were observed. Conclusion One repeated intravenous dose of allogeneic UC-MSCs is safe in people with recent-onset T1D and may result in better islet β cell preservation during the first year after diagnosis compared to standard treatment alone.

Abstract Objective: The objective of this study is comparision of local and distant control rates with high-dose versus standard-dose radiotherapy along with concurrent chemotherapy in esophageal cancer – a prospective randomized study. Materials and Methods: Histologically proven Stage I–III patients with carcinoma esophagus were randomized into two groups. One group has been treated with standard-dose radiotherapy, i.e., a total dose of 50.4 Gy (1.8 Gy/day, 28#, 5 days/week). The other group (study arm) has received high-dose radiotherapy, i.e. a total dose of 64.8 Gy (1.8 Gy/day, 36#, 5 days/week). Both groups have received 2 cycles of 3 weekly concurrent chemotherapy (cisplatin 75 mg/m[2] on day 1 and 5-fluorouracil 750 mg/m[2] continuous intravenous infusion over 24 h on day 1–4). Follow-up response evaluation was done by both endoscopy and computed tomography scan after 6–8 weeks and after 2 months thereafter. Results: Out of a total of 28 patients, 68% showed a complete response, 14% showed partial response, and 18% patients developed progressive disease at first and subsequent follow up (median follow-up of 21 months). Among the complete response patients, rates were higher in high-dose group compared to standard-dose radiotherapy group (71% vs. 64%, P = 0.38). Treatment-related toxicities were acceptable in both groups. Conclusion: High-dose radiotherapy with concurrent chemotherapy seems to be more effective with acceptable toxicity in our study. However, further follow-up and large sample size may be required to validate the current study conclusion.

BACKGROUND After a standard anticoagulation period (3-6 months), the risk of venous thromboembolism recurrence (RVTER) needs to be considered. Such risk is higher in unprovoked events and patients with persistent risk factor. The increase of D-dimer (DD) levels during the therapy seems to be strongly associated to RVTER. The use of rivaroxaban 10 mg/day and apixaban 2.5mg/12h as an extended therapy (ET) after the standard anticoagulation period has been proven to be an effective strategy to prevent recurrence without increasing bleeding events. AIM To assess the effectiveness and safety of reduced doses of rivaroxaban and apixaban as ET in patients with RVTER and to compare their DD levels with those of a control group on anticoagulant therapy at a standard dose. METHODS From April 2016 to June 2020, we included patients with venous thromboembolism (VTE) who received ET with rivaroxaban and apixaban with/at reduced doses. Dose reduction was performed following the clinical algorithm of our unit (Fig. 1). The DD values were determined using HemosIl D-Dimer HS-500 and the cut-off value was established at 500 µg/L DD levels were compared with a control group of 235 patients with VTE who received ET with standard doses of anticoagulation. DD levels were measured at the time of diagnosis (D1), initiation of treatment (D2) and 3 months after treatment (D3). RESULTS From a total of 116 patients (65.5% women), 77.6% (n=90) received rivaroxaban 10 mg/24h and 22.4% received apixaban 2.5 mg/12h as an ET. The mean duration of the initial anticoagulant therapy was 12 +/- 8.8 months. The mean DD value prior to the ET was 388 µg/L. In this group, 63.8% (n=74) was an unprovoked VTE and 17.2% (20) had hereditary thrombophilia. The mean of follow-up time was 6.9 +/- 8.3 months. No recurrences of VTE were observed during the follow-up and only one major bleeding event was reported in a high-bleeding risk patient. We observed a progressive decrease of DD levels from the VTE diagnosis to the last visit, with D1, D2, and D3 values of 987 µg/L ± 324, 388 µg/L ± 134, and 288 µg/L ± 98, respectively. There were no differences in d-dimer concentrations between patients with reduce doses of rivaroxaban or apixaban and the control group with standard doses (D1: 85.6% vs 81%, p =0.22; D2: 10.2% vs 8.0%, p =0.14; and D3: 9.1% vs 9.5%, p =0.18). CONCLUSIONS Our data indicated that an ET strategy with reduced doses of rivaroxaban or apixaban is effective and safe. We did not observe significant differences in DD levels at follow-up compared to the control group receiving a standard dose of anticoagulation. Further studies are needed in order to select and standardize dose reduction criteria in secondary prevention.

e14008 Background: We analyzed the treatment outcome of breast cancer patients with brain metastases (BM) in Korea to identify the prognostic factors and the role of whole brain radiation therapy (WBRT). Methods: Seven hundred thirty patients of breast cancer with BM treated at 17 institutions in Korea from 2000 to 2014 were analyzed. The median follow-up duration was 12 months. The analysis consisted of three cohorts: in cohort A, a total of 730 patients were included; in cohort B, 538 patients with available follow-up imaging after initial brain-directed treatment; and in cohort C, 54 patients receiving salvage WBRT due to recurrent BM after initial Stereotactic radiosurgery or WBRT. Overall survival (OS) was calculated from BM diagnosis in cohort A or from the last day of salvage WBRT in cohort C. Results: Median OS of cohort A was 15 months. In multivariate analysis, histologic grade 3, extracranial metastasis, number of BM > 4, hormone receptor (HR) or HER2 negativity, and shorter time interval to diagnosis of BM were associated with inferior OS. Among 538 patients in cohort B, 201 showed subsequent development of new BM at a median of 11 months after stereotactic radiosurgery or WBRT for the management of initial BM (at 1 year, HR+/HER2- 51.9%, HER2+ 44.0%, and TNBC 69.6%, respectively; p = 0.008). Upfront WBRT reduced subsequent development of new BM, which showed the significant difference among molecular subtypes (HR+/HER2-, 42% reduction at 1 year, p < 0.001; HER2+, 18.5%, p = 0.004; TNBC, 16.9%, p = 0.071). Multivariate analysis showed that shorter time interval to BM, TNBC subtype, extracranial systemic disease, number of BM > 4, and involvement of both tentoria increased subsequent development of new BM. Anti-HER2 therapy for HER2+ patients and upfront WBRT significantly reduced risk of new BM. In cohort C, upfront WBRT prolonged the salvage WBRT-free duration (median 6.9 vs. 8.7 months, p = 0.058). Median OS was 6.8 months after salvage WBRT. Longer interval to salvage WBRT, controlled primary tumor, high dose of salvage WBRT (BED10 > 37.5 Gy), and systemic treatment after salvage WBRT showed better OS. Uncontrolled extracranial systemic disease and salvage WBRT due to local progression without distant intracranial failure showed worse OS. Conclusions: The rates of new BM showed the significant differences among molecular subtypes. Upfront WBRT decreased subsequent development of new BM and this effect was dependent on the molecular subtype as well. Anti-HER2 therapy for HER2+ patients significantly decreased the subsequent development of new BM. On salvage WBRT setting, the patients having high dose of salvage WBRT, stable extracranial systemic disease and subsequent systemic therapy showed better OS.

Aim: This 18 month intervention study aims to determine the efficacy of a lifestyle modification program on prediabetes reversal among Saudi adults. Methods: An 18 month randomized, multicenter trial was conducted among Saudis with prediabetes aged 25–60 recruited from King Salman Hospital and primary care centers in Riyadh, Saudi Arabia. A total of 180 consenting individuals were randomized (1:1) to receive either intensive lifestyle intervention (ILIG) or guidance (control group, CG). ILIG was provided with a personalized lifestyle counseling by nutritionists every 3 months to improve diet and exercise behaviors. CG was given booklets containing information on prediabetes and its prevention. Data from lifestyle assessments and laboratory measurements were analyzed at baseline and every 6 months. The primary outcome was the reversal rate of prediabetes. Results: 158 participants were analyzed (CG:85, ILIG:73) at the 12 month follow-up and 28 participants (CG:11 and ILIG:17) completed the entire 18 month study. Post-intervention, the cumulative incidence of prediabetes reversal in the ILIG was 38 participants (52.1%) which was significantly higher than CG with 26 participants (30.6%) (p = 0.02). Conclusion: A tailored lifestyle intervention is effective in reversing prediabetes, at least for a year, among Arab adults with prediabetes. The challenge of sustaining interest in adopting lifestyle changes for a longer duration should be addressed in this population.
