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.

The purpose of this study was to determine the changing patterns of nausea, vomiting, anorexia and calorie intake. To examine the influence of those variables on the nutritional status of the cancer patients receiving chemotherapy. Method: To assess nutritional status, anthropometry and blood test were performed on 94 stomach cancer patients receiving postoperational chemotherapy on the daily basis. NVA and calorie intake were measured during chemotherapy. Result: 93% of subjects had low level of hemoglobin and 45.7% was below the lymphocyte count. 57% of subjects lost 10% of usual weight. The value of anthropometry was reduced but the difference between pre- and post-chemotherapy did not reach any statistical significance. 27% of subjects was grouped into the malnutritional state. During chemotherapy, the higher the degree of NVA, the less calorie intake. The significant predictors for nutritional status were nausea and calorie intake. Conclusion: The chemotherapy affected the food intake of cancer patients through NVA. Though the influence of chemotherapy on anthropopmetry was not significant in this research, nausea and food intake were the most affecting factors for nutrition of cancer patients. Therefore we need to assess nutritional status and support for cancer patients receiving chemotherapy and to develop an intervention for improvement of symptoms and food intake.

To determine the efficacy of postoperative adjuvant chemotherapy with paclitaxel plus cisplatin (Taxol + DDP, TP therapy) for stage IIA esophageal squamous cell carcinoma (ESCC) and to investigate the expression of RUNX3 in lymph node metastasis-negative esophageal cancer and its relationship with medical prognosis, a retrospective summary of clinical treatment of 143 cases of stage IIA esophageal squamous cell carcinoma patients was made. The patients were divided into two groups, a surgery alone control group (52 patients) and a chemotherapy group that received postoperative TP therapy (91 patients). The disease-free and 5 year survival rates were compared between the groups and a multivariate analysis of prognostic factors was performed. The same analysis was performed for cases classified as RUNX3 positive and negative, with post-operative specimens assessed by immunohistochemistry. Although the disease-free and 5 year survival rates in control and chemotherapy groups did not significantly differ and there was no significance in RUNX3 negative cases, postoperative adjuvant chemotherapy in the chemotherapy group was shown to improve disease-free and 5 year survival rate compared to the control group in RUNX3 positive cases. On Cox regression multivariate analysis, postoperative adjuvant chemotherapy (P<0.01) was an independent prognostic factor for RUNX3 positive cases, suggesting that postoperative TP may be effective as adjuvant chemotherapy for stage IIA esophageal cancer patients with RUNX3 positive lesions.

Purpose: To investigate the efficacy and safety of intraperitoneal chemotherapy (IPC) for patients with gastric cancer and to compare effects between different regimens of IPC. Method: Randomized controlled trials comparing the effects of surgery plus intraperitoneal chemotherapy with surgery alone or comparing the efficacy between different regimens of intraperitoneal chemotherapy were searched for in Medline, Embase, Pubmed, the Cochrane Library and the Chinese BioMedical Disc and so on by two independent reviewers. After quality assessment and data extraction, data were pooled for meta-analysis using RevMan5.16 software. Tests of interaction were used to test for differences of effects among subgroups grouped according to different IPC regimens. Results: Fifteen RCTs with a total of 1713 patients with gastric cancer were included for quality assessment and data extraction. Ten studies were judged to be of fair quality and entered into meta-analysis. Hyperthermic intraoperative intraperitoneal chemotherapy (HR=0.60, P<0.01), hyperthermic intraoperative intraperitoneal chemotherapy plus postoperative intraperitoneal chemotherapy (HR=0.47, P<0.01) and normothermic intraoperative intraperitoneal chemotherapy (HR=0.70, P=0.01) were associated with a significant improvement in overall survival. Tests of interaction showed that hyperthermia and additional postoperative intraperitoneal chemotherapy did not impact on its effect. Further analysis revealed that intraperitoneal chemotherapy remarkably decrease the rate of postoperative hepatic metastasis by 73% (OR=0.27, 95% CI=0.12 to 0.67, P<0.01). However, intraperitoneal chemotherapy increased risks of marrow depression (OR=5.74, P<0.01), fever (OR=3.67, P=0.02) and intra-abdominal abscess (OR=3.57, P<0.01). Conclusion: The present meta-analysis demonstrates that hyperthermic intraoperative intraperitoneal chemotherapy and normothermic intraoperative intraperitoneal chemotherapy should be recommended to treat patients with gastric cancer because of improvement in overall survival. However, it is noteworthy that intraperitoneal chemotherapy can increase the risks of marrow depression, intra-abdominal abscesses, and fever.

Purpose: Multidisciplinary approaches of surgical resection and chemotherapy have been widely used for the treatment of non-metastatic osteosarcomas. We aimed to assess the effect of neoadjuvant chemotherapy for metastasis and disease-specific survival. Materials and Methods: Authors retrospectively reviewed 225 young (<30 years old) and non-metastatic osteosarcoma patients who underwent surgical resection and postoperative chemotherapy between February 1984 and July 2010. Mean age was 14.4 years old (ranged: 4-29 years old) and average follow-up period was 9.1 years (2-28 years). The patients were divided into two groups according to the application of preoperative chemotherapy. Both groups were compared with clinical characteristics, metastasis-free survival and disease-specific survival. Results: All of 225 patients, 32 patients were treated with postoperative chemotherapy and 193 patients were performed preoperative and postoperative chemotherapy. Postoperative chemotherapy group showed significantly high rate of amputation (p<0.001). Metastasis was occurred in 101 patients. Postoperative chemotherapy group indicated significant higher rate of metastasis (69% vs 41%, p=0.004) and early development of metastasis (mean: 11.5 vs 20.3 months, p=0.045) than pre-and postoperative chemotherapy group. Fifty-seven patients were died of osteosarcoma. Postoperative chemotherapy group revealed significant lower rate of 5-year disease-specific survival than pre-and postoperative chemotherapy group (51% vs 84%, p=0.001). Adult (>15 years) and large sized tumor (>8 cm) were meaningful risk factors of metastasis and disease-specific survival. Although, local recurrences were occurred in 13 patients, there was no significant difference. Conclusion: Neoadjuvant chemotherapy offers better disease-specific survival and metastasis-free survival.

Purpose: We aimed to explore whether the prognosis of patients treated with capecitabine and oxaliplatin (XELOX) or S-1 and oxaliplatin (SOX) regimens who received fewer cycles of chemotherapy after D2 radical resection for gastric cancer (GC) would be non-inferior to that of patients who received the standard number of cycles of chemotherapy. Materials and Methods: Data on patients who received XELOX or SOX chemotherapy after undergoing D2 radical resection at Harbin Medical University Cancer Hospital between January 2011 and May 2016 were collected. Results: In patients who received 4, 6, and 8 cycles of chemotherapy, the 5-year overall survival (OS) rates were 59.4%, 64.8%, and 62.7%, respectively. Compared to patients who received 4 cycles of chemotherapy, those who received 6 cycles (hazard ratio [HR], 0.882; 95% confidence interval [CI], 0.599-1.299; P=0.52) or 8 cycles (HR, 0.882; 95% CI, 0.533-1.458; P=0.62) of chemotherapy did not exhibit significantly prolonged OS. The 3-year disease-free survival (DFS) rate of patients who received 4, 6, and 8 cycles of chemotherapy was 62.1%, 67.2%, and 60.8%, respectively. Compared to patients who received 4 cycles of chemotherapy, those who received 6 cycles (HR, 0.835; 95% CI, 0.572-1.221; P=0.35) or 8 cycles (HR, 0.972; 95% CI, 0.606-1.558; P=0.91) of chemotherapy did not show significantly prolonged DFS. However, the 3-year DFS and 5-year OS rates of patients who received 6 cycles of chemotherapy appeared to be superior to those of patients who received 4 and 8 cycles of chemotherapy. Conclusions: For patients with stage III GC, 4 to 6 cycles of XELOX or SOX chemotherapy may be a favorable option. This study provides a rationale for further randomized clinical trials.

Purpose: Peritoneal seeding of gastric cancer is known to have a poor prognosis. With the diagnosis of peritoneal seeding, there is no effective treatment modality. Gastrectomy with chemotherapy or primary chemotherapy is basically one of major options for this condition. This study was conducted to compare the clinical outcomes of these treatments and to identify the better way to improve the prognosis of patients with peritoneal seeding. Materials and Methods: Between 2001 and 2007, gastric cancer patients with peritoneal seeding by preoperative or intraoperative diagnosis were reviewed retrospectively. The enrolled patients were divided as primary gastrectomy and primary chemotherapy group. Clinicopathologic characteristics and clinical outcomes of groups were analyzed and compared. Results: Fifty-four patients were enrolled. 21 patients belonged to the group of primary gastrectomy and 33 patients were to the primary chemotherapy group. Among 33 patients of the primary chemotherapy group, 17 patients were received only chemotherapy and 16 patients were received gastrectomy due to the good responses of primary chemotherapy. The 3 years survival rates were 14% in primary gastrectomy group, 55% in patients who received gastrectomy after primary chemotherapy, and 0% in patients with primary chemotherapy only. Conclusions: Although this study had many limitations, some valuable information was produced. In terms of survival benefits for the gastric cancer patients with peritoneal seeding, primary gastrectomy and additional gastrectomy after primary chemotherapy revealed the better clinical outcomes. But, prospective randomized clinical study and multi-center study should be performed to decide proper treatment for gastric cancer patients with peritoneal seeding.

Surgery is the only curative modality for the treatment of gastric cancer. There has been no drastic improvement in the treatment of gastric cancer with chemotherapy. Clinical trials have attempted to demonstrate the benefit of the preoperative chemotherapy for gastric cancer. The benefit of the use of preoperative chemotherapy or chemoradiotherapy has been demonstrated for other solid cancers such as breast cancer, esophageal cancer and rectal cancer. Despite the rationale of the use of preoperative chemotherapy for patients with gastric cancer, the evidence of positive results with the use of preoperative chemotherapy has not been clear. Recently the British Medical Research Council Adjuvant Gastric Cancer Infusional Chemotherapy (MAGIC) study demonstrated the survival benefit of preoperative and postoperative chemotherapy. However, this study had several problems with the use of a heterogeneous population of patients, the method of surgery and the use of perioperative chemotherapy. Further studies with new drugs are warranted to determine the role of pre-operative chemotherapy for patients with gastric cancer.

Background: Thyroid hormones (TH) are regulated by the hypothalamic-pituitary axis, which plays an important role in cell growth, differentiation, development and other aspects of metabolism. It is believed that an active hypothalamic-pituitary axis increases the susceptibility of thyroid dysfunction during systemic chemotherapy. In order to investigate the relation between thyroid function and chemotherapy the present study was designed to investigate TH in breast cancer patients receiving at least three cycles of chemotherapy. The levels of TH were measured at the baseline and before each cycle of chemotherapy. Materials and Methods: Blood samples for estimation of TH levels were collected from 80 (pre-menopausal-40; post-menopausal-40) breast cancer patients just before they were undergoing - $1^{st}$, $2^{nd}$, $3^{rd}$ and $4^{th}$ cycle of chemotherapy. The serum was separated and $T_3$, $T_4$ and TSH levels were determined by chemiluminescence method. Results: $T_3$ and $T_4$ were found significantly decreased and TSH was found significantly increased after $1^{st}$ (p<0.001), $2^{nd}$ (p<0.0001) and $3^{rd}$ cycle of chemotherapy (p<0.0001). The variation of $T_3$ levels (decreased) and TSH levels (increased) was found more in post-menopausal (p<0.0001) women then in pre-menopausal women after $3^{rd}$ cycle of chemotherapy as compared to baseline (p<0.001). Conclusions: TH were remarkably altered after each cycle of chemotherapy leading to decline in thyroid function of breast cancer patients. Further, the results also indicated that post-menopausal women were more prone towards decline in thyroid function then pre-menopausal women. The present study proposes the monitoring of TH after each cycle of chemotherapy in breast cancer patients.

Background: Platinum-hased chemotherapy for advanced non-small cell lung cancer (NSCLC) is still considered the first choice, presenting a modest survival advantage. However, the patients eventually experience disease progression and require second-line therapy. While there are reliable predictors to identify patients receiving first-line chemotherapy, very little knowledge is available about the prognostic factors in patients who receive second-line treatments. The present study was therefore performed. Methods: We retrospectively reviewed 107 patients receiving second-line treatments from August 2002 to March 2012 in the Dicle University, School of Medicine, Department of Medical Oncology. Fourteen potential prognostic variables were chosen for analysis in this study. Univariate and multivariate analyses were conducted to identify prognostic factors associated with survival. Result: The results of univariate analysis for overall survival (OS) were identified to have prognostic significance: performance status (PS), stage, response to first-line chemotherapy response to second-line chemotherapy and number of metastasis. PS, diabetes mellitus (DM), response to first-line chemotherapy and response to second-line chemotherapy were identified to have prognostic significance for progression-free survival (PFS). Multivariate analysis showed that PS, response to first-line chemotherapy and response to second-line chemotherapy were considered independent prognostic factors for OS. Furthermore, PS and response to second-line chemotherapy were considered independent prognostic factors for PFS. Conclusion: In conclusion, PS, response to first and second-line chemotherapy were identified as important prognostic factors for OS in advanced NSCLC patients who were undergoing second-line palliative treatment. Furthermore, PS and response to second-line chemotherapy were considered independent prognostic factors for PFS. It may be concluded that these findings may facilitate pretreatment prediction of survival and can be used for selecting patients for the correct choice of treatment.
