Background: Cancer care is currently the most important medical issue in Japan. Total pain of cancer patients consists of a combination of four factors: physical, psychological, social distress, and spiritual pain. Previous studies showed female cancer patients ask for more psychological support and seem to suffer different types of distress compared with male patients, for example, appearance-related symptoms. However, other factors of cancer distress related to gender have not been defined comprehensively. The aim of this study is to clarify the gender differences in cancer distress types in order to elucidate the measures that should be taken in Japan to improve the quality of whole cancer care based on gender-based medicine. Methods: The data of new patients who had visited the psycho-oncology outpatient service of Kinki University Hospital during the period of May 2013 to October 2015 were collected. Demographic factors and all assessed items were extracted from the patients' medical charts retrospectively. Based on an inquiry of cancer patients in 2010, each item representing the four factors of "total pain" of cancer patients was chosen, i.e., physical distress (pain, changes in appearance), psychological distress (anxiety, depression), social distress (family problems, job-related problems), and spiritual pain; together with sexuality issues, and answers were analyzed. Hospital Anxiety Depression Scale (HADS) was used for the assessment of psychological distress. Chi-square test and Fisher's exact test were performed for gender differences in the cancer distress types. Pearson's analysis and multiple logistic regression analysis were performed for the association of gender with each item. Results: The data of 101 cancer patients were analyzed and there were more female patients than male patients (female: male ratio = 71:30). Female cancer patients were more likely to suffer from psycho-social issues such as changes in appearance, family problems and sexuality issues than male patients, and male patients were more likely to have spiritual pain. Conclusions: There were gender differences in the distress types of cancer patients. In order to improve the quality of whole cancer care, more intensive intervention by medical professionals and social support is needed from the viewpoint of gender-based medicine and psycho-oncology.

Background: As the number of immigrants to Japan increases, the health problems of foreign nationals also have an increasing impact on Japanese medical institutions. The aim of this study was to clarify the Japan-specific health problems related to both the physical and psychological symptoms of foreign nationals from the viewpoint of psychosomatic medicine. The second aim was to clarify the measures that should be taken in Japan and similar countries where immigration may still be considered less than common. Case Presentation: The study period was from June 2004 to May 2015. The data of non-Japanese patients who had visited the Department of Psychosomatic Medicine, Kinki University Hospital and its branches, Sakai Hospital and Nihonbashi Clinic, were collected. All patients were aged 16 years or over. Multiple factors, such as age, sex, nationality, length of stay, marital status, employment status, level of Japanese proficiency, clinical symptoms, physical and psychiatric diagnosis, psycho-social factors and therapy were retrospectively analyzed from the medical charts of 20 non-Japanese patients. Cases were divided into two groups; early onset and late onset cases. This study showed that multiple factors related to the health problems of non-Japanese patients were combined and had a mutual influence, however, they can be summarized into two important clinical observations. These are 1) cultural differences, and 2) language barriers related to both the physical and psychological symptoms of non-Japanese patients from the viewpoint of psychosomatic medicine. Conclusions: Future efforts should focus on sensitizing health care professionals in Japan to the psychosomatic problems of non-Japanese patients as well as on facilitating medical systems with services such as medical professional interpreters and liaison-consultation models. It is essential to take measures against language barriers and to promote the field of transcultural psychiatry and psychosomatic medicine in Japan. In addition, the Japanese government should introduce a more comprehensive social support system for non-Japanese people. [ABSTRACT FROM AUTHOR]

Kampo medicines are currently manufactured under strict quality controls. The Ministry of Health, Labour and Welfare of Japan has approved 148 Kampo formulas. There is increasing evidence for the efficacy of Kampo medicines, and some are used clinically for palliative care in Japan. The specific aim of this review is to evaluate the clinical use of Kampo medicines in palliative care in the treatment of cancer. The conclusions are as follows: Juzentaihoto inhibits the progression of liver tumors in a dose-dependent manner and contributes to long-term survival. Hochuekkito has clinical effects on cachexia for genitourinary cancer and improves the QOL and immunological status of weak patients, such as postoperative patients. Daikenchuto increases intestinal motility and decreases the postoperative symptoms of patients with total gastrectomy with jejunal pouch interposition, suppresses postoperative inflammation following surgery for colorectal cancer, and controls radiation-induced enteritis. Rikkunshito contributes to the amelioration of anorectic conditions in cancer cachexia-anorexia syndrome. Goshajinkigan and Shakuyakukanzoto reduce the neurotoxicity of patients with colorectal cancer who undergo oxaliplatin and FOLFOX (5-fluorouracil/folinic acid plus oxaliplatin) therapy. Hangeshashinto has the effect of preventing and alleviating diarrhea induced by CPT-11(irinotecan) and combination therapy with S-1/CPT-11. O'rengedokuto significantly improves mucositis caused by anticancer agents. [ABSTRACT FROM AUTHOR]

Emergency post-coital contraception (EC) is an effective method of preventing pregnancy when used appropriately. EC has been available since the 1970s, and its availability and use have become widespread. Options for EC are broad and include the copper intrauterine device (IUD) and emergency contraceptive pills such as levonorgestrel, ulipristal acetate, combined oral contraceptive pills (Yuzpe method), and less commonly, mifepristone. Some options are available over-the-counter, while others require provider prescription or placement. There are no absolute contraindications to the use of emergency contraceptive pills, with the exception of ulipristal acetate and mifepristone. This article reviews the mechanisms of action, efficacy, safety, side effects, clinical considerations, and patient preferences with respect to EC usage. The decision of which regimen to use is influenced by local availability, cost, and patient preference. [ABSTRACT FROM AUTHOR]

Genetic differences in humans cause clinical difficulties in opioid treatment. Previous studies indicate that a single nucleotide polymorphism in the catechol-O-methyltransferase (COMT) gene (rs4680; p.Val158Met) may present as a predictive biomarker for the response to morphine treatment. In our previous pilot exploratory study, patients with a G/G genotype were demonstrated to require a higher dose of morphine, compared with patients with A/A and A/G genotypes. In the present study, the aim was to replicate the findings in an independent cohort of opioid-treatment-naïve patients exhibiting various types of cancer. This prospective study was conducted from 2011 to 2012 at the Kindai University Faculty of Medicine. A total of 50 patients with opioid-treatment naïve and histologically confirmed malignant neoplasms who were scheduled to undergo opioid treatment were evaluated in the present study. Assessments were conducted pre-treatment (day 1), post-treatment (day 1), and one week after treatment (day 8). The required dose of morphine on day 1 was significantly higher for patients with the G/G genotype of COMT, compared with those with the A/A and A/G genotypes (P=0.013). The results of the present study provide additional evidence that the COMT genotype may be a predictive biomarker for the response to morphine treatment. [ABSTRACT FROM AUTHOR]

There have been few studies on predictive biomarkers that may be useful to select the most suitable opioids to optimize therapeutic efficacy in individual patients with cancer pain. We recently investigated the efficacy of morphine and oxycodone using single nucleotide polymorphisms (SNPs) of the catechol-O-methyltransferase (COMT) rs4680 gene as a biomarker (RELIEF study). To explore additional biomarkers that may enable the selection of an appropriate opioid for individual patients with cancer pain, three SNPs were examined: C-C motif chemokine ligand 11 (CCL11; rs17809012), histamine N-methyltransferase (HNMT; rs1050891) and transient receptor potential V1 (TRPV1; rs222749), which were screened from 74 pain-related SNPs. These SNPs, which were identified as being significantly associated with the analgesic effect of morphine, were then used to genotype the 135 patients in the RELIEF study who had been randomized into a morphine group (n=69) or an oxycodone group (n=66). The present study then assessed whether the SNPs could also be used as selective biomarkers to predict which opioid(s) might be the most suitable to provide pain relief for patients with cancer. Oxycodone tended to provide superior analgesic effects over morphine in patients carrying the genotype AA for the CCL11 rs17809012 SNP (P=0.012 for interaction), suggesting that it could serve as a potential biomarker for personalized analgesic therapy for patients suffering with cancer pain.

Background: Cancer patients experience pain that has physiological, sensory, affective, cognitive, behavioral, and sociocultural dimensions. Opioids are used in treatment of pain in patients with various types of cancer. We previously showed that the catechol-O-methyltransferase (COMT) genotype is related to the plasma level of morphine and the required dose of morphine in an exploratory prospective study. The findings showed that a group of patients with a GG single nucleotide polymorphism (SNP) rs4680 in COMT required a significantly higher dose of morphine than a non-GG group. A biomarker for selection of opioids for cancer pain relief would be particularly useful clinically, and therefore we have planned a randomized comparative study of morphine and oxycodone, using the COMT rs4680 SNP as a biomarker. This study is aimed at verifying the assumption that patients in the GG group require an increased morphine dose for pain relief.Methods: The RELIEF study is a randomized, multi-institutional, open-label trial with a primary endpoint of the proportion of subjects requiring high-dose opioids, as calculated from the dose of a rescue preparation administered on day 0. Secondary endpoints include the Hospital Anxiety and Depression Scale, Short form McGill Pain Questionnaire-2, European Organization for Research and Treatment of Cancer QLQ-C15-PAL, Pain Catastrophizing Scale, and adverse events, Eligibility criteria are patients with advanced carcinoma with non-daily use of opioids in initial screening for registration; and cancer pain targeted for daily opioid treatment, NSAIDs or acetaminophen, NRS ≥3(average over 24 h), opioid-treatment naive within 30 h, no chemotherapy, radiotherapy, or bisphosphonate administration newly started within 2 weeks, and written informed consent at the time of second registration. Between November 2014 and June 2017, an estimated 110 patients from two sites in Japan were randomized (1:1) to morphine or oxycodone in GG and non-GG groups.Discussion: A method for selection of appropriate opioids in cancer patients is a high unmet medical need. This study was designed to evaluate the efficacy of different opioids in patients with cancer based on gene polymorphism, as the first potential multi-institutional registration trial to be conducted in cancer patients with pain.Trial Registration: UMIN000015579 Date of registration: 4 November 2014. It is updated once every six months, the latest update is 30 June 2017. Trial status. The enrollment started in November 2014. At the time of manuscript submission (July 2017), Three-quarters of patients have participated. We thus expect to complete the recruitment by March 2018. [ABSTRACT FROM AUTHOR]

Carnitine deficiency is reportedly associated with increased pain sensation in diabetes mellitus and fibromyalgia, but the association between serum carnitine concentration and cancer pain has not been fully elucidated. We investigated the incidence of carnitine deficiency in patients with cancer pain, and examined the effect of the patients' demographic and clinical characteristics on pain intensity and carnitine deficiency. The serum carnitine concentration was measured in 50 patients with cancer pain receiving non-steroidal anti-inflammatory drugs, but not opioids. Multivariate regression analysis was used to determine the association of carnitine concentration, pain intensity, age and gender with hemoglobin and C-reactive protein (CRP) concentrations. Carnitine deficiency was detected in 9 of the patients (18.0%) and found to be significantly correlated with an elevated CRP concentration (P=0.039). In conclusion, although there does not appear to be an association between carnitine deficiency and cancer pain, it may be affected by inflammation or infection. [ABSTRACT FROM AUTHOR]

Background Eribulin is a recently approved new therapeutic option for patients with metastatic breast cancer. According to several reports, eribulin has limited ability to cross the blood brain barrier. Recently, capecitabine and eribulin have been recognized as drugs with similar application for patients with advanced breast cancer. Although there have been several case reports describing the efficacy of capecitabine against brain metastases, no report of eribulin demonstrating efficacy for brain metastases exists today. Case presentation We describe a case of a 57-year-old Japanese woman who was diagnosed with breast cancer stage IV metastasized to multiple organs including liver and lung. After she received 3 regimens, she showed evidence of brain metastases, and whole brain radiation therapy was performed. Lapatinib and capecitabine was then administered as fourth-line chemotherapy, but the patient was hospitalized due to the exacerbation of interstitial pneumonitis and progression of brain and liver metastases. To control the systemic disease, eribulin was commenced as fifth-line chemotherapy. One month later, a significant response of brain metastases had been achieved, and this response has persisted for the last 4 months. We now describe a remarkable antitumor effect of eribulin against brain metastases from breast cancer. This case is the first report which indicates potential treatment of brain metastases using this medication. Conclusion This report suggests that eribulin treatment may be beneficial for breast cancer patients with brain metastases progressing after whole brain radiation therapy. However, further clinical studies are warranted to determine the clinical effect of eribulin in brain metastases. [ABSTRACT FROM AUTHOR]
