Heptaplatin, a new platinum derivative, has several contradicting reports on the nephrotoxicity. Therefore, the aim of this study is to compare the toxicities of heptaplatin-containing regimens in the chemotherapy. This study was performed retrospectively on seventy-seven patients with advanced gastric cancer who did not receive chemotherapy within the last 1 months before taking of heptaplatin- or cisplatin-containing chemotherapy. The 38 patients among total patients was received heptaplatin-containing regimens (26 with SEF regimens: heptaplatin/epirubicin/5-FU, 12 with SF regimens: heptaplatin/5-FU) and the rest 39 patients was received cisplatin-containg regimens (11 with CEF regimens: cisplatin/epirubicin/5-FU, 28 with ELF regimens: epirubicin/leucovorin/5-FU). Before and after the chemotherapy serum creatinine (Scr) and proteinuria were measured by urine stick test in all patient groups. Also Scr was measured a day before the second cycle and did not vary significantly between groups. However Scr on cycle 3 were significantly higher in SEF and SF groups. In case of proteinuria, it was more frequent on cycle 1 in heptaplatin/5-FU group. Proteinuria before and after on cycle 2 was not different between the two cisplatin -containing groups, but was more frequent in heptaplatin-containing groups. The reason why the Scr measured was not so different could be because we excluded the patients who received only one cycle of heptaplatin and changed the regimen due to signs of nephrotoxcity. As the results nephrotoxicity such as protienuria was appeared to be more frequent with heptaplatin-treated patients. It suggests that the clinical consequences of the toxicity need to further evaluation and also the modalities to prevent or minimize nephrotoxicity of heptaplatin should be studied for future utilization of the drug.

Background : The overall response (20-30%) to chemotherapy in non-small cell lung cancer (NSCLC) is quite poor. Heme oxygenase-1 (HO-1) is the rate-limiting enzyme in heme degradation. There is increasing evidence suggesting that the induction of HO-1 might have an important protective effect against oxidative stress including cisplatin containing chemotherapy. This study retrospectively investigated the relationship between HO-1 expression and the response to chemotherapy containing cisplatinin advanced NSCLC patients. Material and Methods : The medical records including the responses to chemotherapy of fifty nine cases were evaluated retrospectively, and the tissue samples of these patients were immunohistochemically stained for HO-1. Results : Forty three of the fifty nine patients(72.8%) showed positive staining for HO-1 in their cancer tissues. There was no significant difference according to the cell type, stage and tumor size. In addition, there was no correlation between HO-1 expression and the responses to chemotherapy. Conclusion : HO-1 expression in tumor tissue dose not predict the response to cisplatin containing chemotherapy in advanced NSCLC. Further prospective studies with a larger number of patients will be needed to confirm these results.

Background: Acute kidney injury is an important issue in chemotherapy receiving patients an neutrophil gelatinase-associated lipocalin has been proposed as a novel marker. We here aimed to assess the role of urinary levels for assessment after platin exposure. Materials and Methods: Patients who had treated with cisplatin or carboplatin or oxaliplatin containg regimens were included in this study. Baseline and postchemotherapy serum urea, creatinine, urine neutrophil gelatinase-associated lipocalin and urine creatinine levels were determined. To avoid the effects of hydration during chemotherapy infusion the urinary neutrophil gelatinase-associated lipocalin/urine creatinine ratio was used to determine acute kidney injury. Results: Of a total of 42 patients receiving platin compounds,14 (33.3%) received cisplatin containing regimens, 14 (33.3%) received carboplatin and 14 (33.3%) oxaliplatin. The median age was 60 (37-76) years. Nineteen of the patients (45.2%) had lung cancer, 12 (28.6%) colorectal cancer and 11 (26.2%) others. The median pre and post chemotherapy urine neutrophil gelatinase-associated lipocalin/urine creatinin ratio was 15.6 ng/mg and 35.8 ng/mg (p=0.041) in the cisplatin group, 32.5 ng/mg and 86.3 ng/mg (p=0.004) in the carboplatin group and 40.9 ng/mg and 62.3 ng/mg (p=0.243) in the oxaliplatin group. Conclusions: Nephrotoxicity is a serious side effect of chemotherapeutic agentslike cisplatin and carbopaltin, but only to a lower extent oxaliplatin. All platin compounds must be used carefully and urine neutrophil gelatinase-associated lipocalin measurement seems to be promising in detecting acute kidney injury earlier than with creatinine.

Objective: To observe the short-term efficacy, long-term survival time and adverse responses with nedaplatin (NDP) or cisplatin (DDP) concomitant with other chemotherapy in treating non-small cell lung cancer. Materials and Methods: A retrospective, randomized, control study was conducted, in which 619 NSCLC patients in phases III and IV who were initially treated and re-treated were randomly divided into an NDP group (n=294) and a DDP group (n=325), the latter being regarded as controls. Chemotherapeutic protocols (CP/DP/GP/NP/TP) containing NDP or DDP were given to both groups. Patients in both groups were further divided to evaluate the clinical efficacies according to initial and re-treatment stage, pathological pattern, type of combined chemotherapeutic protocols, tumor stage and surgery. Results: The overall response rate (ORR) and disease control rate (DCR) in the NDP group were 48.6% and 95.2%, significantly higher than in the DDP group at 35.1% and 89.2%, respectively (P<0.01). In NSCLC patients with initial treatment, squamous carcinoma and phase III, there were significant differences in ORR and DCR between the groups (P<0.05), while ORR was significant in patients with adenocarcinoma, GP/TP and in phase IIIa (P<0.05). There was also a significant difference in DCR in patients in phase IIIb (P<0.05). According to the statistical analysis of survival time of all patients and of those in clinical phase III, the NDP group survived significantly longer than the DDP group (P<0.01). The rates of decreased hemoglobin and increased creatinine, nausea and vomiting in the NDP group were evidently lower than in DDP group (P<0.05). Conclusion: NDP concomitant with other chemotherapy is effective for treating NSCLC, with higher clinical efficacy than DDP concomitant with chemotherapy, with advantages in prolonging survival time and reducing toxic and adverse responses.

Aims: To study the effectiveness of human recombinant endostatin injection (Endostar(R)) combined with cisplatin doublets in treating advanced non-small cell lung cancer (NSCLC), and to evaluate outcome by CT perfusion imaging. Methods: From April 2011 to September 2014, 76 patients with advanced NSCLC who were treated with platinum-based doublets were divided into group A (36 patients) and group B (40 patients). Endostar(R) 15mg/day was administered 4 days before chemotherapy and combined with chemotherapy from day 5 in group A, and combined with chemotherapy from the first day in Group B. Endostar(R) in the two groups was injected intravenously for 14 days. Results: Treatment effectiveness in the two groups differed with statistical significance (p<0.05). Effectiveness evaluated by CT perfusion imaging, BF, BV, MTT and PS also demonstrated significant differences (all p<0.05). Adverse reactions in the two groups did not significantly vary (p> 0.05). Conclusions: The response rate with Endostar(R) administered 4 days before chemotherapy and combined with chemotherapy from day 5 in group A was better than Endostar(R) combined with chemotherapy from the first day, and CT perfusion imaging could be a reasonable method for evaluation of patient outcomes.

Purpose: Chemotherapy-induced anemia (CIA) is one of the most important causes of anemia in cancer patients. This study was conducted to describe the prevalence and characteristics of CIA in solid cancer patients in the Chinese population, and to explore the relationship of white blood cell (WBC) or platelet decrease with CIA. Methods: Data on age, gender, tumor diagnosis, anti-cancer treatment and blood cell analyses were available from 220 untreated non-anemic cancer patients who received at least 2 cycles of chemotherapy, and the data were analyzed to assess their relationship with CIA or its severity. Results: 139 patients (63.2%) presented anemia, most being Grade 1 or 2. Esophageal and lung cancers were associated with a high prevalence. G3/4 leucopenia and decrease of platelets were identified as independent risk factors for the occurrence of CIA. Moreover, G3/4 leucopenia, decrease of platelet and G3/4 thrombocytopenia were found to be also associated with the severity of CIA. Cisplatin-containing regimens were a main potential factor in causing CIA, although significant association was only found on univariate analysis. Conclusion: Anemia or decrease in hematoglobin are common in Chinese cancer patients receiving chemotherapy. Cisplatin-containing regimens might be an important factor influencing the occurrence of CIA. Our analysis firstly described some risk factors, such as decrease of platelets or WBCs, severity of leucopenia or thrombocytopenia, associated with the occurrence and severity of CIA.

Introduction: Lung cancer is extremely harmful to human health and has one of the highest worldwide incidences of all malignant tumors. Approximately 80% of lung cancers are classified as non-small cell lung cancers (NSCLCs). Cisplatin-based multidrug chemotherapy regimen is standard for such lesions, but drug resistance is an increasing problem. F-box/WD repeat-containing protein 7 (FBW7) is a member of the F-box protein family that regulates cell cycle progression, and cell growth and differentiation. FBW7 also functions as a tumor suppressor. Methods: We used cell viability assays, Western blotting, and immunofluorescence combined with siRNA interference or plasmid transfection to investigate the underlying mechanism of cisplatin resistance in NSCLC cells. Results: We found that FBW7 upregulation significantly increased cisplatin chemosensitivity and that cells expressing low levels of FBW7, such as NCI-H1299 cells, have a mesenchymal phenotype. Furthermore, siRNA-mediated silencing or plasmid-mediated upregulation of FBW7 resulted in altered epithelial-mesenchymal transition (EMT) patterns in NSCLC cells. These data support a role for FBW7 in regulating the EMT in NSCLC cells. Conclusion: FBW7 is a potential drug target for combating drug resistance and regulating the EMT in NSCLC cells.

Aim: Tumors of upper gastrointestinal tract are among the cancers that have a quite lethal course. Cytotoxic chemotherapy is the most efficient therapeutic modality for metastatic gastric cancer. In patients who do not respond to first-line treatment, the response rate to second-line therapies is generally low and the toxicity rates high. This study concerned the efficacy and the side effect profile of second-line therapy with irinotecan in the patients who were being followed-up with the diagnosis of metastatic gastric cancer in $\dot{I}$zmir, Turkey. Materials and Methods: We retrospectively evaluated the efficacy and toxicity in 31 patients with metastatic gastric adenocarcinoma who presented to the polyclinic of Medical Oncology of Izmir Ataturk Education and Research Hospital between May 2008 and July 2011. All received chemotherapy regimens containing cisplatin, fluoropyrimidine (5-FU) and docetaxel as the first-line therapy for late stage disease. Irinotecan as a single agent was given at a dose of 210 mg/$m^2$ on each 21 days. Irinotecan (180 mg/$m^2$ on day 1), 5-FU (500 mg/$m^2$ on days 1-2) and leucovorin (LV; 60 mg/$m^2$ on days 1-2) as a combined regimen were given over a 14 day period. Results: Median age was 54 (range, 31-70). Irinotecan was given as a combined regimen for median 6 cycles (range, 3-12) and as a single agent for median 3 cycles (range, 1-10). Metastases were detected in one site in six patients (19%), in two different sites in 17 patients (55%) and in three or more sites in eight patients (26%). Four patients (12.9%) showed partial response and six patients (19.3%) showed stable disease. Progression-free survival (PFS) was found to be 3.26 months (95% CI, 2.3-4.2). Median overall survival (OS) was found to be 8.76 months (95% CI, 4.5-12.9). The most commonly seen grade 3/4 side effect was neutropenia but the the therapy was generally well-tolerated. Conclusions: In this study, it was demonstrated that second-line therapy with irinotecan given following the first-line therapy with cisplatin, fluoropyrimidine (5-FU) and docetaxel was efficient and safe. Further studies are needed for confirmation.

Purpose: To evaluate the efficacy of dolasetron mesylate in controlling nausea and vomiting in the first 24 hours and to extend these comparisons over the next 4 days in patients receiving moderately emetogenic chemotherapy. Methods: This was a single center, open-labeled study with single arm. Dolasetron (1.8 mg/kg) was given intravenously (I.V.) prechemotherapy with 10 mg of dexamethasone IV, followed 24 hours later by oral dolasetron (200 mg once daily) for the subsequent 4 days. The frequency of vomiting, severity of nausea and the presence of rescue antiemetics were assessed daily. Results: Of 30 patients enrolled, 28 were eligible and evaluable for the efficacy. Four out of 28 patients had complete control of nausea and vomiting without any rescue antiemetics through 5 days. The complete control got better as time went by with the rates of 17.9/46.4/42.9/53.6/60.7% on days 1 to 5. Vomiting was better controlled than nausea in both cisplatin-containing and non-containing chemotherapy. The adverse events were mild to moderate degrees of headache, diarrhea and fever, but were recovered spontaneously. Conclusion: Dolasetron was effective and safe for the control of nausea and vomiting in the patients with moderately emetogenic chemotherapeutic agents.
