PURPOSEThe incidence of symptomatic brain metastasis at diagnosis in non–small-cell lung cancer (NSCLC) is 5%-10%, and up to 40% develop during the disease course. There is a paucity of data supporting the role of brain imaging at diagnosis in asymptomatic cases particularly from resource-constraint settings. Here, we present our experience of mandatory baseline brain imaging with contrast-enhanced computed tomography (CECT) scans of all patients with NSCLC.MATERIALS AND METHODSThis was a prospective observation study of patients with NSCLC with mandatory baseline brain CECT and a CNS examination. All histology proven patients with NSCLC diagnosed between January 2018 and October 2019 were included irrespective of stage.RESULTSA total of 496 patients were enrolled. The median age was 57 years (range, 23-84) with majority being males (75%) and smokers (66%). The prevalence of epidermal growth factor receptor mutations and anaplastic lymphoma kinase fusions was 33.4% and 12%, respectively. Brain imaging leads to upstaging in 7% cases. The prevalence of brain metastases was 21% (n = 104), with half being asymptomatic (51%). Factors associated with higher proportion of brain metastasis were young age (≤ 40 years), adenocarcinoma histology, poor Eastern Cooperative Oncology Group performance status (3 and 4), and high neutrophil-lymphocyte ratio (NLR) (> 2.5). After a median follow-up of 10.8 months (95% CI, 7.33 to 12.73), the median overall survival was 7.46 versus 12.76 months (hazard ratio 0.67; 95% CI, 0.46 to 0.96; P = .03) in patients with and without brain metastases, respectively. On multivariate analyses, high NLR and molecular graded prognostic assessment affected the overall survival significantly.CONCLUSIONIn our study, 21% of patients had brain metastasis at diagnosis detected with a mandatory baseline brain imaging with CECT. NLR and molecular graded prognostic assessment are significant predictors of survival in patients with brain metastasis.

Background: Patients with multiple myeloma (MM) aged ≤ 65 to 70 years, with a good Eastern Cooperative Oncology Group performance status and no major comorbid conditions, are considered potential candidates for autologous stem cell transplant (ASCT) and will be treated with novel agent-based induction therapy for 4 to 6 cycles before ASCT., Patients and Methods: We analyzed the data from 326 patients with MM who had received novel agent-based induction before ASCT at our center to evaluate the effect of induction therapy on ASCT response, stem cell mobilization, engraftment characteristics, and survival. The median age was 52 years (range, 29-72 years), 216 patients were men (66.3%), 32.7% had stage III using the Revised Multiple Myeloma International Staging System, and 15.8% had high-risk cytogenetics. Of the 326 patients, 75 (23.0%) had undergone ASCT in second remission after salvage therapy for relapse. Also, 194 patients (59.5%) had received doublet induction therapy and 132 (40.5%) had received triplet induction therapy., Results: Triplet-based induction therapy was superior to doublet-based therapy for response (95.4% vs. 84.02%; P < .003), stem cell mobilization (CD34 +  ≥ 2 × 10 6 /kg; 88.6% vs. 76.8%; P < .005), and lower 100-day transplant-related mortality (P < .001). The ≥100 day post-ASCT overall response (97.4% vs. 91.7%; P = .124) and complete response (72.5% vs. 68.0%; P = .38) rates were similar. At a median follow-up of 62.5 months, the overall survival (97.5 months vs. 100.0 months; P = .606) and progression-free survival (54.5 months vs. 57 months; P = .515) were similar between the triplet and doublet induction groups., Conclusion: An initial response (chemosensitivity) to induction therapy will prepare patients better for subsequent consolidation therapy and ASCT, leading to favorable outcomes., (Copyright © 2020 Elsevier Inc.

Background: Platinum-based combination chemotherapy is recommended as the standard treatment for patients with advanced non-small-cell lung cancer (NSCLC), but its benefit is limited to patients with performance status (PS) of 0 or 1. However, it is not clear whether these benefits apply to patients with poor performance status (PS 2 and above) and there are no predictors of outcome to suggest whom to treat. The patients with poor performance status (PS 2 and above) accounts for a significant portion (up to 30%) of patients of our practice. In this retrospective analysis, we have analyzed our experience of chemotherapy in patients with poor performance status., Method: A retrospective analysis of patients of advanced NSCLC with poor PS (ECOG PS 2 or more), treated with chemotherapy from October, 2016 to June, 2018 was done. Patients with driver mutations who were treated with first line tyrosine kinase inhibitors were excluded. Hospital case records were reviewed for baseline characteristics, treatment details, and outcome data. Kaplan-Meier curves were drawn to estimate progression free survival. Log-rank test was used to assess factors affecting survival. Data was analyzed using STATA ver 11 (StataCorp. 2009. College Station, TX: StataCorp LP). P value <0.05 was taken as significant., Result: A total of 96 patients were included in the analysis. The median age of the patients was 62 years (range 30-84 years). Majority (67.7%) was males and 65% patients were smokers (current or former). Patients with ECOG PS (Eastern Cooperative Oncology Group Performance Status) of 2 constituted 64.5% of this cohort and 34 patients (33.5%) had an ECOG PS of 3 or 4. The most common chemotherapy regimen used was combination of weekly paclitaxel (60 mg/m 2 ) and carboplatin (AUC2) in 57.8%. Most patients (64%) could complete 4 or more cycles of chemotherapy, however, 15 patients (15.7%) could receive only 1 cycle. Grade 3⁄4 toxicities were observed in 22 (23%) % patients, which were hematological in most cases (anemia and thrombocytopenia). At least one point improvement in ECOG PS from baseline during chemotherapy was observed in 43 patients (45%) after 4 cycles of chemotherapy. Objective response and disease control rates were 20% and 48.42%, respectively. After a median follows-up of 11.2 months, median progression free survival was 6.3 months (95% confidence interval 5-10.63). On univariate analysis, we found that male sex and use of weekly paclitaxel-carboplatin were associated with better progression-free survival PFS., Conclusion: Systemic chemotherapy in modified doses and schedules in advanced NSCLC patients with PS 2 and above is feasible and may be associated with better symptom palliation with clinical benefit and improved survival., (Copyright © 2020.
