Purpose: The purpose of this study was to identify factors that influence medication adherence in colorectal cancer patients receiving oral chemotherapy. Methods: One hundred and nine colorectal cancer patients receiving oral chemotherapy were recruited in the cross-sectional survey design. A survey including medication adherence, knowledge about chemotherapy, self-efficacy, depression and symptom experience were completed. Results: The level of medication adherence was $7.38{\pm}.80$. Medication adherence showed significant differences according to perceived health status and combination of IV chemotherapy. Medication adherence was significant correlated with self-efficacy, depression and symptom experience. On stepwise regression analysis, the most important factors related to the medication adherence were symptom experience, perceived health status and combination of IV chemotherapy. These variables explained 17% of medication adherence. Conclusion: The level of medication adherence in colorectal cancer patients receiving oral chemotherapy was relatively high. It is important to develop nursing intervention for medication adherence in colorectal cancer patients that focus on symptom experience and to consider about perceived health status and combination of IV chemotherapy.

Malignant pleural mesothelioma (MPM) is an aggressive, treatment-resistant, and generally fatal disease. A 68-year-old male who was diagnosed with MPM at another hospital came to our hospital with dyspnea. We advised him to take combination chemotherapy but he refused to take the treatment. That was because he had already received chemotherapy with supportive care at another hospital but his condition worsened. Thus, we recommended photodynamic therapy (PDT) to deal with the dyspnea and MPM. After PDT, the dyspnea improved and the patient then decided to take the combination chemotherapy. Our patient received chemotherapy using pemetrexed/cisplatin. Afterwards, he received a single PDT treatment and then later took chemotherapy using gemcitabine/cisplatin. The patient showed a survival time of 27 months, which is longer than median survival time in advanced MPM patients. Further research and clinical trials are needed to demonstrate any synergistic effect between the combination chemotherapy and PDT.

Immune checkpoint inhibition has been established as a new treatment option for various types of carcinoma, and many clinical trials are being actively conducted as a treatment for advanced or metastatic gastric cancer, either as a monotherapy with an immune checkpoint inhibitor or as a combination therapy with standard chemotherapy. In the CheckMate-649 clinical trial to confirm the efficacy of the combination of nivolumab and chemotherapy (FP) in advanced gastric cancer and gastroesophageal junction cancer, nivolumab group showed improvement in overall survival in programmed death ligand 1-positive cancer patients compared with placebo group. Also, the combination therapy of pembrolizumab, trastuzumab and chemotherapy (FP) in first-line treatment was tested through the KEYNOTE-811 trial. The pembrolizumab group showed 22.7% of improvement in objective response rate compared with placebo group. Accordingly, the combination of nivolumab/pembrolizumab with standard chemotherapy was approved for the first-line treatment. In KEYNOTE-059 trials for patients with progressive disease after at least two lines of chemotherapy, pembrolizumab monotherapy showed improvement in objective response rate and overall survival, and the use of pembrolizumab was approved for the third-line or more treatment. In this article, we review the result of clinical trials related to immune checkpoint inhibitors that have been recently introduced in the treatment of gastric cancer.

A Miniature Schnauzer presented with bilateral mucopurulent nasal discharge and sneezing. Computed tomography of the skull revealed exudates in the nasal cavity and frontal gyrus. Nasal swab cytology showed features of an epithelial-origin tumor. Histopathologic evaluation of the biopsy specimen revealed irregular proliferation of epithelial cells and necrotized tissue. Positive immunohistochemical staining confirmed the epithelial origin of the cells. The dog was diagnosed with nasal carcinoma and was treated with a chemotherapy protocol of carboplatin and piroxicam. This report confirms the effectiveness of combination chemotherapy only without radiotherapy in a dog with nasal carcinoma and provides a guideline for providing alternative treatment.

Tomographic examination requires several times of exposure usually, therefore, reduction of radiation dose per exposure without loss of image quality proves of great benefit to patient. We compared the exposure doses under the following experimental conditions, A and B. A is the combination of SRO 380(rare earth screen) and SRH(high contrast film) with additional Cu filters or without. B is the widely used combination which is BH-III and Cronex-4 without additional filter. As a result, comparing with the condition B, the condition A with additional filter of Cu 0.15 mm + Al 0.7 mm, Cu 0.4 mm+ Al 0.4 mm and Cu 0.8 mm showed better Image quality and lower surface dose, 44 %, 31 % and 24 % of the condition B, respectively.

This study is aimed to investigate the effects of intravenous Cultivated Wild Ginseng Pharmacopuncture(CWGP) and the FOLFIRI chemotherapy combination on recurred and metastatic ascending colon cancer patient. A 42-years-old man was diagnosed as ascending colon adenocarcinoma on 9th Mar. 2011. After performing right hemicolectomy and 12 cycles of FOLFOX chemotherapy recurrence at hemicolectomy site and metastases in liver, spleen and lungs were found on 7th Feb. 2012. Intravenous CWGP were performed during total 12 cycles of FOLFIRI chemotherapy from 3rd Mar. 2012 to 27th Sep. 2012. The effects and toxicities of CWGP and FOLFIRI chemotherapy combination were evaluated with PET torso(AA) and National Cancer Institute-Common Toxicity Criteria. The tumor mass in the splenic hilum and liver S4 was disappeared and multiple pulmonic lymph nodules were decreased in size. The recurred lesion on the site of right hemicolectomy showed no changes. During the treatment the patient had no toxicity over grade 1.

Background: We assessed the efficacy and toxicity of ifosfamide and doxorubicin combination chemotherapy (CT) regimen retrospectively in Turkish patients with recurrent or metastatic nasopharyngeal carcinoma (NPC) previously treated with platinum-based chemotherapy. Methods: A total of thirty patients who had received cisplatin based chemotherapy/chemoradiotherapy as a primary treatment received ifosfamide 2500 $mg/m^2$ days 1-3, mesna 2500 $mg/m^2$ days 1-3, doxorubicin 60 mg/m2 day 1 (IMA), repeated every 21 days. Eligible patients had ECOG PS< 2, measurable recurrent or metastatic disease, with adequate renal, hepatic and hematologic functions. Results: Median age was 47 (min-max; 17-60). Twenty six (86.7 %) were male. Median cycles of chemotherapy for each patient were 2 (range:1-6). Twenty patients were evaluable for toxicity and response. No patient achieved complete response, with nine partial responses for a response rate of 30.0% in evaluable patients. Stable disease, and disease progression were observed in five (16.7%) and six (20.0%) patients, respectively. Clinical benefit was 46.7%. Median time to progression was 4.0 months. Six patients had neutropenic fever after IMA regimen and there were one treatment-related death due to tumor lysis syndrome in first cycle of the CT. No cardiotoxicity was observed after CT and treatments were generally well tolerated. Conclusion: Ifosfomide and doxorubicin combination is an effective regimen for patients with recurrent and metastatic NPC. For NPC patients demonstrating failure of cisplatin based regimens, this CT combination may be considered as salvage therapy.

Background: Some recent clinical trials have been conducted to evaluate a combination of EGFR- TKI with chemotherapy for advanced NSCLC patients as second-line therapy, but the results on the efficacy of such trials are inconsistent. The aim of this meta-analysis was to evaluate the efficacy and safety of combination of EGFR-TKI and chemotherapy for patients with advanced NSCLC who failed first-line treatment. Materials and Methods: We searched relative trials from PubMed, EMBASE, ASCO Abstracts, ESMO Abstracts, Cochrane Library and Clinical Trials.gov. Outcomes analyzed were overall response rate (ORR), progression- free survival (PFS), overall survival (OS) and major toxicity. Results: Seven trails eventually were included in this meta-analysis, covering 1,168 patients. The results showed that the combined regimen arm had a significant higher ORR (RR 1.76 [1.16, 2.66], p=0.007) and longer PFS (HR 0.75 [0.66-0.85], p<0.00001), but failed to show effects on OS (HR 0.88 [0.68-1.15], p=0.36). In terms of subgroup results, continuation of EGFR-TKI in addition to chemotherapy after first-line EGFR-TKI resistance confered no improvement in ORR (RR 0.95 [0.68, 1.33], p=0.75) and PFS (HR 0.89[0.69, 1.15], p=0.38), and OS was even shorter (HR1.52 [1.05-2.21], p=0.03). However, combination therapy with EGFR-TKI and chemotherapy after failure of first-line chemotherapy significantly improved the ORR (RR 2.06 [1.42, 2.99], p=0.0002), PFS (HR 0.71 [0.61, 0.82], p<0.00001) and OS (HR 0.74 [0.62-0.88], p=0.0008), clinical benefit being restricted to combining EGFR-TKI with pemetrexed, but not docetaxel. Grade 3-4 toxicity was found at significantly higher incidence in the combined regimen arm. Conclusions: Continuation of EGFR-TKI in addition to chemotherapy after first-line EGFR-TKI resistance should be avoided. Combination therapy of EGFR-TKI and pemetrexed for advanced NSCLC should be further investigated for prognostic and predictive factors to find the group with the highest benefit of the combination strategy.
