Background: Megestrol acetate (MA) is a steroid origin medicine often used for control of cachexia in oncologic palliative care. Thrombosis is a common problem in oncology patients. One question is whether MA can cause thrombosis. This retrospective, registry-based analysis was therefore conducted to assess thrombotic processes in oncology patients using MA concurrent with chemotherapy. Materials and Methods: Data on oncology patients at the metastatic stage using MA were obtained from the archives of our center. Outcomes of patients were evaluated for thromboembolic events (VTEs) during treatment. Results: Ninety-seven oncology patients with a median age of 62 (33-84) years were included. During the median follow-up of 17 months, 58 (59.8%) died leaving 39 (31.2%) still alive. Median overall survival (OS) was 19 months (6-180). Mean time of MA use was 8.69 months(${\pm}3.53$), with a median dose of 160mg (range 160-480mg). Eleven VTEs were detected after MA use, 4 of these in pancreatic cancer cases. The patients with thrombosis non-significantly had worse OS, than those without thrombosis (p=0.106). Conclusions: This trial revealed that the 11.3% of all patients developed thrombosis,who had been treated with MA and chemotherapy concomittantly. There was no statistically significant difference regarding to occurrence of thrombotic process, among the patients receiving different chemotherapy regimens with MA concomittantly. Pancreatic cancer seemed to be related to thrombosis rather than MA use.

Despite a considerable improvement in antiemetic chemotherapy and the use of antiemetic prophylaxis for decades, there are still numerous cancer patients suffering from anorexia and nausea after chemotherapy, which forces them to postpone or refuse treatment. This case report is about a 66-year-old female patient diagnosed with malignant lymphoma of the small intestine who underwent right hemicolectomy. After the tumor and the colon adjacent to it were surgically removed, the patient continued to undergo chemotherapy. Chemotherapy-induced anorexia and nausea appeared but were well treated with administration of Dokhwaljihwang-tang-gamibang. During the treatment, no adverse effect related to this Korean medicine was reported. The outcome was evaluated by the functional assessment of anorexia/cachexia therapy (FAACT); the total score increased from 85 to 130 within 12 days, and the symptoms were alleviated. This improvement might suggest the feasibility of Dokhwaljihwang-tang-gamibang to help cancer patients suffering from chemotherapy-induced anorexia and nausea.

Due to poor nutrition and abnormal energy metabolism, cancer patients typically experience the loss of muscle mass. Although the diabetic conditions or dyslipidemia have been reported as a causal link of cancer but the consequence of such conditions in relation to gain or loss of skeletal muscle mass in cancer patients has not been well documented. The purpose of this study was to investigate the relationship of lean body mass and systemic parameters related to lipid metabolism in non-diabetic cancer patients using data from the Korean National Health and Nutrition Examination Survey (KNHANES) 2008-2011. As results the level of serum total cholesterol (total-C) was negatively associated with both total lean body mass and appendicular lean body mass in cancer patients after adjustment for sex, physical activity, energy intake and comorbidity. The associations between consumption of dietary factors (energy, carbohydrate, protein and fat) and lean body mass were disappeared after adjusting comorbidities of cancer patients. Multivariate-adjusted linear regression analysis by quartiles of serum total-C showed that higher quartile group of total-C had significantly lower percent of lean body mass than reference group in cancer patients. The data indicate that serum lipid status can be the potential estimate of loss of skeletal muscle mass in cancer patients and be referenced in nutrition care of cancer patients under the onset of cachexia or parenteral/enteral nutrition. This data need to be confirmed with large pool of subjects and should be specified by stage of cancer or the site of cancer in future studies.

Colorectal cancer has become a major disease threatening human health. To establish animal models that exhibit the characteristics of human colorectal cancer will not only help to study the mechanisms underlying the genesis and development effectively, but also provide ideal carriers for the screening of medicines and examining their therapeutic effects. In this study, we established a stable, colon cancer nude mouse model highly expressing green fluorescent protein (GFP) for spontaneous metastasis after surgical orthotopic implantation (SOI). GFP-labeled colon cancer models for metastasis after SOI were successfully established in all of 15 nude mice and there were no surgery-related complications or deaths. In week 3, primary tumors expressing GFP were observed in all model animals under fluoroscopy and two metastatic tumors were monitored by fluorescent imaging at the same time. The tumor volumes progressively increased with time. Seven out of 15 tumor transplanted mice died and the major causes of death were intestinal obstruction and cachexia resulting from malignant tumor growth. Eight model animals survived at the end of the experiment, 6 of which had metastases (6 cases to mesenteric lymph nodes, 4 hepatic, 2 pancreatic and 1 mediastinal lymph node). Our results indicate that our GFP-labeled colon cancer orthotopic transplantation model is useful with a high success rate; the transplanted tumors exhibit similar biological properties to human colorectal cancer, and can be used for real-time, in vivo, non-invasive and dynamic observation and analysis of the growth and metastasis of tumor cells.

Background: Correlation between colorectal cancer (CRC) and abdominal obesity has been established, but there is a paucity of data on non-obese CRC patients. The aim of this study was to establish the characteristics of CRCs that occur in such patients. Materials and Methods: Consecutive CRC patients without cachexia were included. Unintended body weight loss, T4- or M1-staged CRCs, extensive lymph node involvement, or synchronous malignancy were classified as cachectic conditions. Abdominal fat volumes were measured using a multidetector CT unit with a software (Rapidia, INFINITT, Seoul, Korea). Results: Of the newly-diagnosed CRC patients, 258 non-cachectic and 88 cachectic patients were analyzed. The cancer size (p<0.001) and T stage (p<0.001) were inversely correlated with body mass index (BMI), visceral fat and subcutaneous fat volumes. Cancer size was the only independent factor related to BMI (p=0.016), visceral fat volume (p=0.002), and subcutaneous fat volume (p=0.027). In non-cachectic patients, a significant inverse correlation was found only between the cancer size and visceral fat volume (p=0.017). Conclusions: Non-obese CRC patients tend to have larger CRC lesions than their obese counterparts even under non-cachectic conditions. Such an inverse correlation between cancer size and visceral fat volume suggests that considerable CRCs are not correlated with abdominal obesity.

Objectives : Anorexia is the primary symptom impinging cancer patients' Quality of Life. It is usually accompanied by gastrointestinal symptoms(GI symptoms). Thus, to measure anorexia symptom precisely, assessing anorexia and GI symptoms together is recommended. This study was designed to analyze cancer-related anorexia assessment tools, extract GI symptoms included in these tools and investigate usefulness of instruments in clinical trials. Methods : Instruments were selected by searching PubMed, PROQOLID database. We analyzed instruments by number of items, assessment method, type of question, GI symptoms. Results : 9 instruments were selected to assess cancer-related anorexia symptom. Most tools adopt Likert scale as response scale and 'during past week' as recall period. Assessment method of all 9 instruments is the self-administration. Questions measuring anorexia are able to be sorted into 3 forms (frequency, severeness, distress of anorexia symptom). Among the GI symptoms, nausea is included in all 9 instruments. In clinical trials of cancer-related anorexia, Edmonton Symptom Assessment Scale(ESAS) and Functional Assessment of Anorexia/Cachexia Therapy Questionnaire(FAACT) were selected as endpoint measure. Conclusions : The result showed that FAACT is the only specialized tool to assess cancer-related anorexia. To measure cancer-related anorexia precisely, the need to develop new instrument exists.

Objectives: The object of this study was to observe antitumor, anticachexia and immunomodulatory effects of Shipyeukmiyeugi-eum(SYM) on human breast cancer cell, MCF-7, xenograft Balb/c nu-nu nude mice. Methods: Three different dosages of SYM-125, 250 and 500 mg/kg were orally administered once a day for 28 days from 11 days after tumor cell inoculation, and the changes on the body weights, tumor volume and weights, weights of spleen and popliteal lymph node and epididymal fat, serum IL-6 and IFN-${\gamma}$ levels, NK cell and peritoneal macrophage activities, splenic TNF-${\alpha}$, IL-$1{\beta}$ and IL-10 contents were observed. In addition, histopathological observations of apoptotic cell, spleen, popliteal lymph node and cervical brown adipose were also detected. The results were compared with a potent cytotoxic estrogen receptor antagonist, Tamoxifen 20 mg/kg treated mice. Results: Tumor volumes and weights were decreased without cytotoxic effects on the both MCF-7 and MCF-10A cells as results of all three different dosages of SYM treatment. And weights of body, spleen, popliteal lymph node, epididymal fat, serum IFN-${\gamma}$, NK cell, peritoneal macrophage activities, splenic TNF-${\alpha}$, IL-$1{\beta}$ and IL-10 contents were increased with decrease of serum IL-6. At histopathological observations, apoptotic tumor cells, spleen, popliteal lymph node and cervical brown adipose tissue were increased. That means tumor-related immunosuppress and cachexia were markedly inhibited by SYM treatment as compared with tumor-bearing mice. On the other hand, Tamoxifen showed marked cytotoxic effects against MCF-7 and MCF-10A, decreases of tumor volume and weights, and increases of apoptotic tumor cells and related decreases of tumor cell volumes, but tamoxifen markedly deteriorated the tumor-related immune-suppress and cachexia. Conclusions: The results obtained in this study suggest that SYM showed favorable anticancer effects and anticachexic effects on the MCF-7 cell xenograft through immunomodulatory effects. SYM did not induce any cytotoxic effects against both normal and cancer cells.

Nuclear factor-${\kappa}{B}$ (NF-${\kappa}{B}$) belongs to a group of homodimers and heterodimers of Rel/NF-${\kappa}{B}$ proteins that bind to DNA target sites, where they directly regulate gene transcription. The activation of NF-${\kappa}{B}$ has been shown to mediate inflammation and suppress apoptosis. Activated NF-${\kappa}{B}$ has been found n various inflammatory diseases such as rheumatoid arthritis, Atherosclerosis, asthma, nflammatory bowel disease, and Helicobacter pylori-associated gastritis and associated with cancer, cachexia, diabetes, euthyroid sick syndrome, and AIDS.

The aim of this study was to evaluate the antitumor activities of Typhae pollen (TP) by confirming in vitro cytotoxicity and in vivo anti-tumor and immune-modulatory effect with anti-cachexia effect. The MTT assay is used in HepG2 cell to detect potential cytotoxic activities of aqueous extract of Typhae pollen (TPe). After HepG2 tumor cell implantation, eight mice per groups were assigned to six groups. Three different dosages of TPe (500, 250 and 125 mg/kg) were orally administered in the amount of $10m{\ell}/kg$ and sorafenib also administered 20mg/kg, every day for 35 days from 28 days after the tumor cell implantation. We observed the changes on body weights, tumor volume and weights, lymphatic organ, serum interferon $(IFN)-{\gamma}$ levels, splenocytes and peritoneal NK cell activity, splenic tumor necrosis factor $(TNF)-{\alpha}$, interleukin $(IL)-1{\beta}$, IL-10 contents. Periovarian fat weights, serum IL-6 levels, thicknesses of deposited periovarian adipose tissue and mean diameters were also detected to monitor the tumor-related anticachexic effects. In tumor masses, the immunoreactivities of cleaved caspase-3 and cleaved poly (ADP-ribose) polymerase (cleaved PARP) - apoptotic marks, cyclooxygenase-2 (COX-2), inducible nitric oxide synthases (iNOS) and tumor necrosis factor $(TNF)-{\alpha}$ were additionally observed by immunohistochemistry. The results were compared with sorafenib. Decreases of COX-2 were demonstrated in sorafenib and TPe treated mice and also increases of iNOS in tumor masses were observed in TPe, not in sorafenib. TPe increased periovarian fat pad weights compared with tumor-bearing controls and sorafenib treated mice. TPe showed increases of splenic $TNF-{\alpha}$, IL-10 and $IL-1{\beta}$, serum $IFN-{\gamma}$ and NK cell activities corresponding to increases of spleen weights, lymph node weights and non-atrophic changes of lymph nodes. Our results show oral treatment of TPe 500, 250 and 125 mg/kg has potent in vitro and in vivo antitumor activities through modest cytotoxic effects, immunomodulatory effects and apoptotic activities in HepG2 tumor cells. In addition, TPe can prevent cancer related cachexia.
