Purpose: This systematic analysis was conducted to evaluate the efficacy and safety of pemetrexed-based chemoradiotherapy in treating patients with locally advanced or metastatic esophageal cancer. Methods: Clinical studies evaluating the efficacy and safety of pemetrexed based regimens on response and safety for relevant patients were identified using a predefined search strategy. Pooled response rates (RRs) were calculated. Results: For pemetrexed-based regimens, 4 clinical studies including 47 patients with locally advanced or metastatic esophageal cancer were considered eligible for inclusion. Systematic analysis showed that, in all patients, the pooled RR was 51% (24/47). Major adverse effects of grade III/IV were esophagitis, neutropenia, thrombocytopenia, anemia anorexia, fatigue, diarrhea, dysphagia and vomiting. No treatment related death occurred with pemetrexed-based treatment. Conclusion: This systematic analysis suggests that pemetrexed based radiotherapy is associated with reasonable activity and good tolerability in treating patients with locally advanced or metastatic esophageal cancer.

Objective: To further observe the efficacy and safety of pemetrexed, combined with Irinotecan or oxaliplatin or cisplatin in treating patients with advanced gastric cancer as second-line or third-line chemotherapy. Methods: From September 2013 to February 2014 we recruited 50 patients with advanced gastric cancer, with stage IV disease or postoperative recurrence, or unresectable. Then treated with pemetrexed based chemotherapy. After two cycles of treatment, efficacy and toxicity were evaluated. Results: Pemetrexed based chemotherapy was used as second-line in 33 patients, RR(CR+PR) is 41.2%. And achieved 36.4% when used as third-line. Overall response rate of 50 patients treated with Pemetrexed based treatment was 38% (CR+PR). Treatment related side effects were bone marrow suppression, vomiting, hepatic dysfunction and malaise.No treatment related death occurred. Conclusions: Treatment with pemetrexed based chemotherapy is active and is well tolerated in patients with advanced gastric cancer.

Gastric cancer (GC) is one of the most common malignancies worldwide. The ABCB1 protein, a member of the ATP-binding cassette (ABC) transporter family, encoded by the ABCB1 gene, considerably influences the distribution of drugs across cell membranes as well as multidrug resistance (MDR) of antineoplastic drugs. In contrast to the extensive knowledge on the pharmacological action of ABCB1 protein, the correlation between the clinical-pathological data and ABCB1 protein expression in patients with GC remains unclear. The aim was to investigate association between ABCB1 expression and overall survival in GC patients. Human tumor fragments from 57 GC patients were examined by immunohistochemistry assay. We observed lower survival rate of patients with GC who were positive for ABCB1 expression (p=0.030). Based on these observations, we conclude that GC patients with positive ABCB1 protein immunohistochemical expression in their tumors suffer shorter overall survival.

The study aimed to find out to what degree suicidal thoughts and associated factors affect the suicide risk of advanced cancer patients. The frequency of suicidal thoughts among patients with cancer, especially in the advanced stages, is about 3 times greater than the adult average in South Korea. We recruited 457 participants with four types of cancers (colon, breast, cervical, and lung) using stratified sampling. Data collection was carried out through one-on-one interviews by trained nurses using a structured questionnaire. Advanced cancer patients with high, vs. low, levels of anxiety and pain had a higher suicide risk. In contrast, having one's spouse as the primary care provider was associated with a low suicide risk. Overall, the three factors of anxiety, pain, and the primary caregiver being one's spouse explained 17.2% of the variance in suicide risk. In conclusion, we derived influencing factors of suicide risk using a sample of patients with various types of advanced cancer. The results provide systematic baseline data for preparing nurse-led interventions to prevent suicidal thoughts and suicide attempts among advanced cancer patients.
