Introduction: Diffuse-type gastric carcinoma with signet ring cells (SRC) is a poor-prognosis subtype of gastric cancer, highly ma- lignant with stromal induction .Till now searching for molecularly targeted drugs for these cases is disappointing. Case Presentation: A 59-year-old female diagnosed with gastric cancer was admitted to Aria Hospital in Rasht, Iran in 2011. She underwent a subtotal gastrostomy as complete tumor resection with free surgical margins and adequate lymph node dissection. Diffuse infiltrating carcinoma was poorly differentiated. SRC carcinoma, tumor invades at the serosal surface, vascular and per- ineurial invasion, but no regional lymph node metastasis was reported. Then, the patient received chemotherapy with Taxotere plus oxaliplatine and 5-fluorouracil (5 FU) for 6 cycles and 20 sessions of radiation. At present, 6 years after the initial surgery, the patient is alive without any recurrence. Conclusions: In the current case report the vital role of a multi-disciplinary approach to save cancer patients’ lives is strongly appreciated.

Background: In patients undergoing Cardiopulmonary Bypass (CPB) with extracorporeal circulation, the rapid restoration of blood flow to the ischemic tissue induces cardiac damage termed as myocardial Ischemic Reperfusion (I/R) injury.Objectives: In the current study, the researchers hypothesized that Dexmedetomidine (DEX) modulates I/R injury in Coronary Artery Bypass Graft Surgery (CABG) with Cardiopulmonary Bypass (CPB). Methods: This randomized, double-blind, clinical trial took place in a university affiliated Hospital, Gilan, Iran. From April 2016 to March 2017, 114 eligible patients undergoing elective and isolated CABG were randomized to receive either DEX infusion 0.3 to 0.5 μg/kg/hour before induction of anesthesia till 12 hours postoperatively (group D) or normal saline as placebo (group C). Theendpoints were used to assess creatinine phosphokinase-MB (CKMB) and cardiac troponin I (CTnI) levels at four measurement time points, including baseline (T0) and 6, 12, 24, and 48 hours after the operation (T0 - T4).Results: Overall, 114 patients’ data were analyzed; group D (n = 58) and group C (n = 56). No significant differences were found between the two groups, in view of baseline characteristics. Following CPB, a marked increase in CKMB and CTnI plasma levels was observed in both groups compared with baseline (P = 0.0001). Serum CKMB levels increased from 2.27 ± 0.59 to 7.81 ± 1.39, and 2.22 ± 0.64 to 7.46 ± 1.25 and CTnI levels from 10.22 ± 0.17 to 4.89 ± 1.1, and 0.27 ± 0.28 to 4.5 ± 1.4 in groups C and D, respectively (P = 0.0001). According to CKMB, there was a significant difference between the two groups at T2 (P = 0.002) and T3 (P = 0.0001), and based on CTnI at T2 (P = 0.004) and T3 (P = 0.0001). However, no significant difference was observed at the other measurement point times. No adverse effect was recorded due to this intervention. Conclusions: Perioperative DEX in cardiac surgery appears safe, with properties to alleviate I/R injury. Obviously, future standard trials are required to find optimal intervention strategies.

Background: In patients with coronary artery stenosis, coronary artery bypass graft surgery (CABG) is the most effective strategy to limit infarct size and improving outcomes. However, the rapid restoring of blood flow to the tissue can paradoxically induce cardiac damage. This phenomenon termed as myocardial ischemic/reperfusion (I/R) injury which is exacerbated under cardiopulmonary bypass (CPB) and is the cause of poor clinical outcomes. Therefore, it is essential to search for novel strategies with further cardio protective effects.Objectives: In the current study, we investigated the effects of selenium (Se) administration on I/R injury in CABG patients.Methods: This randomized double-blind clinical trial was conducted in the department of cardiac surgery of a university hospital in North of Iran from May 2015 to September 2015. One hundred and ten patients undergoing an elective isolated CABG surgery were divided into two groups using randomized fixed quadripartite blocks. They received either intravenous Se before induction of anesthesia, or normal saline as placebo. Cardiac troponin I (CTnI) and creatine kinase-MB (CKMB) were measured as biomarkers at four measurement point times, before the intervention (T0), at 6, 12, 24 and 48 hours after the surgery (T1-T4).Results: Finally, data from 104 patients were analyzed, the Se (n = 53) and control (n = 51) groups. There was no significant difference between the two groups regarding the baseline characteristics. In both groups CPB caused a markedly increase in CKMB and CTnI plasma concentrations compared to the baseline (P = 0.0001). Based on CKMB, there was no significant difference between the two groups at any point times, T0 (P = 0.357), T1 (P = 0.751), T2 (P = 0.46), T3 (P = 0.16) and T4 (P = 0.053). According to CTnI, there was just a significant difference between the two groups at T1 (P = 0.011) but not at T2 (P = 0.116), T3 (P = 0.09) and T4 (P = 0.634). No adverse effect was recorded linked to our intervention.Conclusions: Selenium can alleviate I/R injury in short time. Further well-planned trials are needed to find the optimized administration method to achieve the most beneficial effects to the patients.
