Introduction: Data regarding long-term survival and prognosis in loco-regionally advanced, non-metastatic gastric cancers (GC) using perioperative chemotherapy and D2 lymphadenectomies from India is scarce.
Materials And Methods: The study is a retrospective evaluation of locally advanced gastric cancers who received epirubicin-oxaliplatin-capecitabine (EOX) as perioperative therapy from May 2013 to December 2015 at Tata Memorial Hospital, Mumbai. The report concentrates on long-term survival outcomes and prognostic factors. Event-free survival (EFS) and overall survival (OS) were calculated using Kaplan-Meier method.
Results: Two hundred and sixty-eight patients were started on EOX regimen, of which 200 patients (74.6%) underwent definitive resection with D2 lymphadenectomy. With a median follow-up of 52.7 months, the estimated median 3-year and 5-year EFS were 38.5% and 36.3% respectively. The estimated median 3-year and 5-year OS were 41.7% and 37.6% respectively. Patients younger than age 40 years [HR 1.55 (1.034-2.321); p = 0.034] and with poorly differentiated histology [HR 0.65 (0.446-0.944); p = 0.024] had inferior OS compared to their counterparts.
Conclusions: Long-term OS in Indian patients in non-metastatic GC with EOX chemotherapy and D2 lymphadenectomy is similar to previously published Western data. Younger Indian patients fare worse than their older counterparts and this needs further evaluation.

Improving Medical Education in Oncology: Enhancing Students' Understanding of Cancer Treatments Through Multidisciplinary Clinical Rotations.

Cancer remains a leading cause of mortality worldwide, requiring physicians to understand multidisciplinary treatments. This study assessed the impact of a clinical rotation in a cancer center on medical students' knowledge of cancer treatments from a multidisciplinary perspective. A traditional single-department rotation was compared to a multidisciplinary rotation to determine whether broader exposure enhances knowledge and prepares students for multidisciplinary care.

Purpose: To investigate the effect of preoperative prealbumin levels on long-term survival outcomes after gastrectomy in patients with gastric cancer (GC) dichotomized based on age.
Methods: This retrospective cohort study included consecutive patients who underwent radical gastrectomy for primary stage I-III GC between May 2006 and March 2017. Patients were allocated to groups based on age (≥ 70 or < 70 years) and subgroups based on prealbumin levels (high, ≥ 22 mg/dL; moderate, 15-22 mg/dL; or low, < 15 mg/dL), and multivariate Cox regression was used for survival analyses.
Effective eradication of acute myeloid leukemia stem cells with FLT3-directed antibody-drug conjugates.

Department of Medicine III, LMU University Hospital, LMU Munich, Munich, Germany.
Refractory disease and relapse are major challenges in acute myeloid leukemia (AML) therapy attributed to survival of leukemic stem cells (LSC). To target LSCs, antibody-drug conjugates (ADCs) provide an elegant solution, combining the specificity of antibodies with highly potent payloads. We aimed to investigate if FLT3-20D9h3-ADCs delivering either the DNA-alkylator duocarmycin (DUBA) or the microtubule-toxin monomethyl auristatin F (MMAF) can eradicate quiescent LSCs.

Traumatic brain injury (TBI) is a risk factor for neurodegeneration, however little is known about how this kind of injury alters neuron subtypes. In this study, we follow neuronal populations over time after a single mild TBI (mTBI) to assess long ranging consequences of injury at the level of single, transcriptionally defined neuronal classes. We find that the stress-responsive Activating Transcription Factor 3 (ATF3) defines a population of cortical neurons after mTBI.
