Primary mediastinal immature teratoma is a rare germinal tumor which includes various elements of mature teratoma, choriocarcinoma, yolk sac carcinoma, embryonal carcinoma, and seminoma in some proportions. The tumor is virtually restricted to young man and the response to surgery and radiotherapy are poor. Recently, we experienced a case of primary mediastinal immature teratoma with elevated serum [-HCG and [-fetoprotein in 18 years old man. The well-encapsulated mass, weighing 4.5 kg, was completely resected and then adjuvant combination chemotherapy was tried with Vincristine, Bleomycin, and Cisplatin. Radical excision of tumor and adjuvant chemotherapy would appear to produce better result than have been reported in other cases. The postoperative course was uneventful and the tumor markers were returned to normal range.

The incidence of colorectal cancer (CRC) has continuously increased and CRC is a major cause of cancer-related death. Systemic chemotherapy has resulted in a significant improvement in overall survival in metastatic CRC. The development of biologic agents for the treatment of CRC has additionally expanded the options for the treatment. Cetuximab is useful in KRAS wild type tumors in combination with chemotherapy for metastatic disease in both the first and second line settings. It is also used as monotherapy after failure of both irinotecan and oxaliplatin containing regimens. Panitumumab has similar indications, and is primarily used in patients intolerant to cetuximab due to hypersensitivity reactions. Bevacizumab is primarily used as first line and second line therapy in metastatic CRC. However, the optimal way and duration to combine these chemotherapeutic agents are not yet established.

Background : Small-cell carcinomas of lung have a tendency for rapid growth and early wide metastasis. Despite the high response rates of combination chemotherapy alone or with radiotherapy, the overall long-term survival rate is very disappointing. According to autopsy findings, the common cause of failure is local recurrence in the primary cancer site. Therefore, surgical resection with combined chemotherapy has recently been attempted for very early stage small-cell carcinomas of the lung. Methods : 10 patients (TNM I & II: 5 cases each) undergoing surgical resection for small-cell carcinomas of the lung were treated with adjuvant chemotherapy in an attempt to prolong survival. Of these, 9 patients received chemotherapy, and a retrospective study for survival undertaken (Kaplan-Meier analysis). Results : The median survival time was 26 months, and the 2- and 5-year survival rates were 68.6 and 46.7%, respectively. If the 1 patient not having undergone chemotherapy was excluded, the 2-, 5-year survival rates were 76.2 and 50.8%, respectively? No difference in the survival rate was seen between patients with TNM stages I and II. Conclusion : Adjuvant chemotherapy after surgical resection results in prolonged survival for patients with TNM stages I and II small-cell carcinomas of the lung.

This study was conducted to evaluate the effectiveness of a combination of gemcitabine and nedaplatin therapy among patients with metastatic urothelial carcinoma previously treated with two lines of chemotherapy. Between February 2009 and August 2013, 30 patients were treated with gemcitabine and paclitaxel as a second-line chemotherapy. All had received a first-line chemotherapy consisting of methotrexate, vinblastine, doxorubicin and cisplatin. Ten patients who had measurable histologically proven advanced or metastatic urothelial carcinoma of the urinary bladder and upper urinary tract received gemcitabine $1,000mg/m^2$ on days 1, 8 and 15 and nedaplatin $70mg/m^2$ on day 2 as a third-line chemotherapy. Tumors were assessed by imaging every two cycles. The median number of treatment cycles was 3.5. One patient had partial response and three had stable disease. The disease-control rate was 40%, the median overall survival was 8.8 months and the median progression-free survival was 5.0 months. The median overall survival times for the first-line and second-line therapies were 29.1 and 13.9 months, respectively. Among disease-controlled patients (n=4), median overall survival was 14.2 months. Myelosuppression was the most common toxicity. There were no therapy-related deaths. Gemcitabine and nedaplatin chemotherapy is a favorable third-line chemotherapeutic option for patients with metastatic urothelial carcinoma. Given the safety and benefit profile seen in this study, further prospective trials are warranted given the implications of our results with regard to strategic chemotherapy for patients with advanced or metastatic urothelial carcinoma.

Background: Combination chemotherapy is now considered to be the cornerstone of small cell lung cancer (SCLC). management but the optimal management of limited SCLC is not well defined. The role of thoracic radiotherapy (TRT) is less well established. Recent meta-analyses reports revealed that TRT combined with chemotherapy produce "good" local control and prolonged survival. But other reports that survival was not changed. The liming, dose, volume and fractionation for TRT with the combined chemotherapy of SCLC remains unsettled. In this study, we analyzed the effects according to the timing of thoracic radiotherapy in limited SCLC. Method: All fifty one patients received cytoxan, adriamycin and vincristine(CAV) alternating with etoposide and cisplatin(VPP) every 3 weeks for 6 cycles were randomized prospectively into two groups: concurrent and sequential. 27 patients received 4500cGy in 30 fractions(twice daily 150cGy fractional dose) over 3 weeks 10 the primary site concurrent with the first cycle of VPP(concurrent gorup). 24 patients received 4000 to 5000cGy over 5 or 6 weeks after completion of sixth cycles of chemotherapy(sequential group). Results: 1. Response rates and response duration : Response rates were not significantly different between two groups(p=0.13). But response duration was superior in the concurrent group(p=0.03). 2. Survival duration was nor different between two groups(p=0.33). 3. Local control rate was superior in the concurrent group(p=0.00). 4. Side effects and toxicities: Hematologic toxicities, especially leukopenia, infection and frequency of radiation esophagitis were higher in the concurrent group (p=0.00, 0.03, 0.03). Conclusion: The concurrent use of TRT with chemotherapy failed to improve the survival of limited stage SCLC patients compared with the sequential use of TRT but response duration and local control rate were superior in the concurrent group. Frequency of radiation esophagitis, life threatening hematologic toxicities and infection were more frequent in the concurrent group than sequential group. So, the selection of an optimal schedule of chemotherapy combined with TRT that would lead to a major increase in survival with minimal toxicity is remained to be validated in large scale study in the future.

A chemosensitivity assay with small replicate Mm5mt/cl C3H mammary tumor cell cultures was developed to determine whether changes in viral antigen expression and release into culture fluids could be utilized as an in vitro measure of modulating drug effect. The 52,000 MW viral envelope glycoprotein (gp52) of the mouse mammary tumor virus (MMTV) was measured in culture fluids of control and drug-treated cultures while cell density was simultaneously determined by cell staining and OD 664 nm determination. While extra-cellular gp52 levels and cell density progressively increased over 72 hours for control cultures, declines in both parameters provided dual measures of effect for combination [N(phophonacetyl-L-aspartic acid)+5-fluorouracil], combination 〔N(phophonacetyl-L-aspartic acid )+5-fluoro-5'-deoxyuridine〕and single component treatment of this combination. At each treated time point, thesecombinations begin to produce a greater decline in both cell density and gp52 levels as compared to single drug treatments. These results indicate that N(phopho-nacetyl-L-aspartic acid) in combination can enhance the effectiveness of single drug.

Autophagy is a process of eliminating damaged or unnecessary proteins and organelles, thereby maintaining intracellular homeostasis. Deregulation of autophagy is associated with several diseases including cancer. Contradictory dual roles of autophagy have been well established in cancer. Cytoprotective mechanism of autophagy has been extensively investigated for overcoming resistance to cancer therapies including radiotherapy, targeted therapy, immunotherapy, and chemotherapy. Selective autophagy inhibitors that directly target autophagic process have been developed for cancer treatment. Efficacies of autophagy inhibitors have been tested in various pre-clinical cancer animal models. Combination therapies of autophagy inhibitors with chemotherapeutics are being evaluated in clinal trials. In this review, we will focus on genetical and pharmacological perturbations of autophagy-related proteins in different steps of autophagic process and their therapeutic benefits. We will also summarize combination therapies of autophagy inhibitors with chemotherapies and their outcomes in pre-clinical and clinical studies. Understanding of current knowledge of development, progress, and application of cytoprotective autophagy inhibitors in combination therapies will open new possibilities for overcoming drug resistance and improving clinical outcomes.

This research was conducted to compare differences in colon cancer lymphatic vessel invasion (LVI) with D2-40 antibody labeling and regular HE staining, blood vessel invasion (BVI) with CD34 antibody labeling and HE staining and to assess the possibility of using D2-40-LVI/CD34-BVI in combination for predicting stage II colon cancer prognosis and guiding adjuvant chemotherapy.Anti-D2-40 and anti-CD34 antibodies were applied to tissue samples of 220 cases of stage II colon cancer to label lymphatic vessels and small blood vessels, respectively. LVI and BVI were assessed and multivariate COX regression analysis was performed for associations with colon cancer prognosis. Regular HE staining proved unable to differentiate lymphatic vessels from blood vessels, while D2-40 selectively labeled lymphatic endothelial cell cytosol and CD34 was widely expressed in large and small blood vessels of tumors as well as normal tissues. Compared to regular HE staining, D2-40-labeling for LVI and CD34-labeling for BVI significantly increased positive rate (22.3% vs 10.0% for LVI, and 19.1% vs 9.1% for BVI). Multivariate analysis indicated that TNM stage, pathology tissue type, post-surgery adjuvant chemotherapy, D2-40-LVI, and CD34-BVI were independent factors affecting whole group colon cancer prognosis, while HE staining-BVI, HE staining-LVI were not significantly related. When CD34-BVI/D2-40-LVI were used in combination for detection, the risk of death for patients with two or one positive results was 5.003 times that in the LVI(-)&BVI(-) group (95% CI 2.365 - 9.679). D2-40 antibody LVI labeling and CD34 antibody BVI labeling have higher specificity and accuracy than regular HE staining and can be used as molecular biological indicators for prognosis prediction and guidance of adjuvant chemotherapy for stage II colon cancer.

Purpose: This study was designed to evaluate the effect of home care nursing intervention with parenteral hydration and IV anti-emetic therapy on distress, nutritional status, anxiety, depression and QOL in gynecologic cancer patients who were undergoing combination chemotherapy. Methods: Quasi-experimental design was used to test the intervention. Changes of result variables were measured to evaluate effects of the intervention. variables consisted of serum lab results(auto analytic equipment for lab), symptom distress Scale(McCorkle & Young, 1978; Song et al., 2000), nutritional status(body weight, circumference of upper arm, serum protein, serum albumin, oral intake per day), anxiety(Spielberger, 1972; Kim & Shin, 1978), depression(Zung, 1965; Kim, 1995) and QOL(Padilla et al., 1983; Lee & Jo, 1996). Subjects were selected among gynecologic cancer patients(EG 15 patients and CG 15 patients) by convenient sampling. Data collection was done from June to Nov. in 2000. Data were analyzed by Chi-test and Mann-whitney U test using SPSS Win 10.0. Result: Hypothesis 1, the EG receiving this intervention equals to lab test(Hb & ANC, GOT & GPT, BUN & Cr) the CG, was supported(u=69.50 p=.074; u=94.50, p= .455; u= 89.50, p= .339; u=106.50, p= .803; u=75.00, p= .119; u=97.50, p= .523). Hypothesis 2, the EG has less symptom distress than the CG, was also supported(u=43.50, p= .004). Hypothesis 3, the EG has higher nutritional status than the CG, was partially supported on daily oral intake (u=59.00, p= .025). Hypothesis 4, the EG has less anxiety than the CG, was rejected(u=86.50, p= .280). Hypothesis 5, the EG has less depression than the CG, was rejected(u=203.50, p= .228). and the last hypothesis 6, the EG has higher QOL than the CG was supported (u=51.50, p= .011). Conclusion: Home care nursing intervention undergone in this study was found to be effective to reduce patients' symptom distress and to improve their oral intake and QOL.
