RESUMO

BACKGROUND: Migraine is a common and disabling neurological disorder. Studies on the relationship between migraine and the autonomic nervous system (ANS) have been inconclusive. Moreover, pediatric studies are extremely limited. Therefore, the present study investigated interictal ANS function in adolescent migraineurs. METHODS: We studied 21 patients with migraine and 26 healthy controls. Beat-to-beat blood pressure (BP) and heart rate (HR) were non-invasively and continuously measured in the supine and standing positions. ANS function was evaluated on power spectral analysis of HR variability and diastolic BP (DBP) variability. RESULTS: Heart rate and systolic BP were not different between the two groups in either the supine or standing position. DBP did not differ between groups in the standing position, but was significantly higher in migraineurs in the supine position. The vasoconstrictor index was significantly higher in migraineurs. High-frequency (HF) RR interval variability (RR-HF) and the ratio of the low-frequency (LF) to HF component of RR interval variability (RR-LF/HF) were not different between the two groups in both positions. The LF component of DBP variability (DBP-LF) in the supine position was significantly lower in migraineurs, while DBP-LF during standing in migraineurs was significantly higher than in controls. CONCLUSION: Migraineurs have significantly lower sympathetic vasomotor activity in the supine position, while sympathetic vasomotor activity was hyperresponsive during standing.

RESUMO

OBJECTIVE: Comprehensive assessment of perceived concerns can be used to guide supportive care appropriate to individual cancer patients. This study sought to determine the prevalence of cancer patients' concerns and the degree to which these concerns contribute to patients' quality of life. METHODS: Participants were patients with all types of cancer, who completed an Internet survey questionnaire regarding comprehensive concerns about physical, psychological, psychosocial and economic aspects of having cancer. The questionnaire was based on the newly developed Comprehensive Concerns Assessment Tool and the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire. RESULTS: We obtained complete data from 807 patients. Factors related to 'self-management' concerns were the most common (61.2%), followed by concerns about 'psychological symptoms' (48.5%), 'medical information' (46.2%), 'daily living' (29.9%), 'pain' (17.6%), 'constipation' (15.6%) and other 'physical symptoms' (15.2%). Multiple regression analysis revealed that all concerns except those about 'medical information' significantly contributed to quality of life. CONCLUSIONS: Cancer patients' concerns were shown to be multidimensional and significantly associated with quality of life. Thus, assessment of patients' concerns should be multidimensional in nature, and a multidisciplinary care team should help patients improve their quality of life.

RESUMO

OBJECTIVE: Cancer incidence and the number of cancer patients are increasing in today's aging society. The purpose of this study was to investigate the characteristics of elderly cancer patients' concerns and examine the association between their concerns and quality of life. METHODS: This was a cross-sectional web-based survey completed by ambulatory cancer patients aged 20 years or older. The questionnaire on cancer patients' concerns, comprehensive concerns assessment tool and the European Organization for Research and Treatment of Cancer QLQ-C30 were distributed to the subjects. Multiple regression analysis was conducted to determine which patients' concerns significantly contributed to their quality of life. RESULTS: The final study population consisted of 807 cancer patients, among whom 243 (30%) were elderly (65 years or older). Elderly cancer patients had particular difficulty with self-management, psychological symptoms and medical information, and the prevalence of their concerns was generally lower than that of younger patients, with the exception of physical symptoms. Multiple types of elderly patients' concerns were independently associated with quality of life. CONCLUSIONS: We found that elderly cancer patients suffered from various concerns, thus multidisciplinary intervention is important for providing them with optimal care. The results of this study suggest that elderly cancer patients' quality of life will improve if their concerns are properly handled.

RESUMO

BACKGROUND: Plasma amino acid profiles (PAAPs) vary in individual cancer patients, and it has been suggested that they may be useful for early detection of several types of cancer. We evaluated the diagnostic performance of a profile index for endometrial cancer composed of multiple plasma amino acids as a novel biomarker and compared its diagnostic performance with that of CA125. METHODS: Plasma amino acid levels of 80 patients with endometrial cancer, 122 with benign gynecological diseases, and 240 age- and body mass index-matched control subjects were measured using liquid chromatography and mass spectrometry. After univariate analysis, we applied a multiplex model based on the PAAP multivariate analysis to distinguish patients with endometrial cancer from control subjects. We compared the diagnostic performance of the multiple PAAP index (API) with that of CA125. RESULTS: The levels of several plasma amino acids were significantly different in patients with endometrial cancer. The area under the receiver operating characteristic curves (AUC) used to distinguish endometrial cancer patients from control subjects was 0.94. The AUC for API was significantly larger than that for CA125 (P = 0.0068). For the same specificity of 98.3 %, API showed a significantly higher sensitivity (60.0 %, 95 % CI, 43.3-75.1) than that of CA125 (22.5 %, 95 % CI, 10.1-38.5). In stage I cases, API showed significantly higher positivity than that of CA125 (P = 0.0002). CONCLUSIONS: The sensitivity and disease specificity of API for early-stage detection of endometrial cancer was superior to CA125. This novel plasma biomarker has the potential to become a diagnostic and screening marker for endometrial cancer.

RESUMO

BACKGROUND: Postural tachycardia syndrome (POTS) manifests as marked tachycardia while standing. We noticed two forms of circulatory response to orthostatic stress in POTS. We investigated cardiovascular and autonomic nervous response to orthostatic stress in the two forms. METHODS: We studied 79 patients with POTS and 38 healthy control subjects (Ct). Beat-to-beat blood pressure (BP) and heart rate (HR) were non-invasively and continuously measured in the supine and standing positions. Autonomic nervous function was evaluated on power spectral analysis of HR variability and diastolic BP variability. We divided the subjects into two groups: standing-induced tachycardia (SI group; increase in HR ≥35 beats/min) and supine tachycardia (Su group; standing HR ≥115 beats/min with standing-induced HR increase <35 beats/min). RESULTS: The Su group had higher supine BP and HR compared with the other groups, indicating dominant sympathetic control of the heart in the supine position. While rising, the SI group had a higher increase in HR than the Ct group, indicating excessive withdrawal of vagal tone. The Su group had a smaller increase in HR and a greater decrease of systolic BP and cardiac index by standing compared with the SI group. These results suggest that compensatory mechanisms of sympathetic function during standing failed in the Su group, probably because of exhaustion by the nearly maximum effort to generate sympathetic drive even in the supine position with low central blood volume. CONCLUSION: There is a difference between the two types of POTS, in the balance of resting autonomic function and hemodynamic response to standing.

RESUMO

BACKGROUND: We investigated the association of baseline body mass index (BMI) and weight change since age 20 years with liver cancer mortality among Japanese. METHODS: The data were obtained from the Japan Collaborative Cohort Study for Evaluation of Cancer Risk (JACC Study). A total of 31 018 Japanese men and 41 455 Japanese women aged 40 to 79 years who had no history of cancer were followed from 1988 through 2009. RESULTS: During a median 19-year follow-up, 527 deaths from liver cancer (338 men, 189 women) were documented. There was no association between baseline BMI and liver cancer mortality among men or men with history of liver disease. Men without history of liver disease had multivariable hazard ratios (HR) of 1.95 (95%CI, 1.07-3.54) for BMI less than 18.5 kg/m(2) and 1.65 (1.05-2.60) for BMI of 25 kg/m(2) or higher, as compared with a BMI of 21.0 to 22.9 kg/m(2). BMI was positively associated with liver cancer mortality among women and women with history of liver disease. Weight change since age 20 years was positively associated with liver cancer mortality among women regardless of history of liver disease. Women with history of liver disease had a multivariable HRs of 1.96 (1.05-3.66) for weight gain of 5.0 to 9.9 kg and 2.31 (1.18-4.49) for weight gain of 10 kg or more, as compared with weight change of -4.9 to 4.9 kg. CONCLUSIONS: Both underweight (BMI <18.5 kg/m(2)) and overweight (BMI ≥25 kg/m(2)) among men without history of liver disease, and weight gain after age 20 (weight change ≥5 kg) among women with history of liver disease, were associated with increased mortality from liver cancer.

RESUMO

The Japan Collaborative Cohort Study for Evaluation of Cancer Risk (JACC Study) was established in the late 1980s to evaluate the risk impact of lifestyle factors and levels of serum components on human health. During the 20-year follow-up period, the results of the study have been published in almost 200 original articles in peer-reviewed English-language journals. However, continued follow-up of the study subjects became difficult because of the retirements of principal researchers, city mergers throughout Japan in the year 2000, and reduced funding. Thus, we decided to terminate the JACC Study follow-up at the end of 2009. As a final point of interest, we reviewed the population registry information of survivors. A total of 207 (0.19%) subjects were ineligible, leaving 110 585 eligible participants (46 395 men and 64 190 women). Moreover, errors in coding date of birth and sex were found in 356 (0.32%) and 59 (0.05%) cases, respectively, during routine follow-up and final review. Although such errors were unexpected, their impact is believed to be negligible because of the small numbers relative to the large total study population. Here, we describe the final cohort profile at the end of the JACC Study along with selected characteristics of the participants and their status at the final follow-up. Although follow-up of the JACC Study participants is finished, we will continue to analyze and publish study results.

RESUMO

AIM: Postural tachycardia syndrome (POTS) is one of the most frequent forms of chronic orthostatic intolerance in children and adolescents. The aim of the present study was to examine the influence of a genetic background on POTS. METHODS: A total of 96 children and adolescents with orthostatic dysregulation were studied. The polymorphism of the G protein ß3 subunit (GNB3) C825T and G protein α subunit (GNAS1) T131C of genes encoding components of the autonomic nervous system were determined and compared with circulatory responses to active standing. RESULTS: In the GNB3 gene C825T polymorphism, the CT and TT genotype had a significant lower supine heart rate and a larger increase of heart rate by standing than the CC, associated with evaluated power of the high-frequency component of heart rate variability. According to the criteria of the Japanese clinical guidelines, 48 children were diagnosed as POTS and 30 were as normal responder with somatoform disorder (SD). In GNB3 C825T polymorphism, the TT genotype was more frequently found in the POTS group (45.8%) than in the SD group (20.0%; P = 0.036) [corrected]. In the GNAS1 T393C, the genotype frequencies for the T393C polymorphisms of GNA1 did not differ significantly between the groups. CONCLUSION: The gene polymorphisms GNB3 C825T might be a risk factor for POTS through the enhanced vagal withdrawal of the heart in children and adolescents.

RESUMO

Hot springs are a major tourism resource in nature-based tourism, and the hot springs market is one of the biggest sectors in wellness tourism markets. In the present study, we examine factors contributing to tourism demand for major hot spring resorts in Japan using ordinary least squares regression models and generalized linear mixed models, and compare the estimation results. The results show that significant factors in most of our models are quality of accommodations and the degree of dependence on inbound demand. Furthermore, the number of non-Japanese languages supported on websites of hot spring resorts has a significant impact on inbound demand. Since the results of the present study cover more than 80 hot spring sites, the results highlight common important factors for hot spring resorts. Such widely applicable factors have been missing in previous studies, and the present study fills this research gap.

RESUMO

OBJECTIVE: To analyze large-scale data obtained from telephone cancer consultations and clarify sex differences in the information sought by callers to guide future cancer survivor support. METHODS: We qualitatively analyzed 10,534 cases of telephone consultations with cancer patients. The relationships between callers' words and sex were visualized through a correspondence analysis, and the keywords extracted were visualized with a dependency relationship to the words "worry" and "anxiety," which had a high prevalence in the text data. RESULTS: Most of the male callers sought consultation about stomach cancer (11.8%), the consultations were predominantly about "suspicion of having cancer" (25.2%), and males indicated that the goal was to gather accurate information. Female callers mostly sought consultation about breast cancer (18.4%) were mainly interested in learning about "treatment" (31.0%), and mostly used the keywords "worry" and "anxiety." The total number of callers without a definitive diagnosis accounted for 20% of all consultations. CONCLUSIONS: Healthcare providers need to understand unique sex-based coping styles and perform regular follow-ups. There is also a need for online platforms that provide information from the patient's perspective. PRACTICAL IMPLICATIONS: Providing a cancer consultation support system and easy-to-understand medical information will improve communication between survivors, their families, and medical staff.

RESUMO

Abstract Objective. To assess retrospectively whether continuously high serum alanine aminotransferase (ALAT) levels (<80 IU) in the first three successive years after the diagnosis of liver cirrhosis (LC) are predictive of a subsequent high incidence of hepatocellular carcinoma (HCC) in patients with Child Stage A hepatitis C virus (HCV)-LC. Material and methods. The study comprised 132 HCV-LC (Child Stage A) patients who had not received interferon therapy but had been treated with anti-inflammatory agents. At the end of a 3-year follow-up after the diagnosis of LC, the patients were subdivided into three groups according to their serum ALAT levels and the subsequent incidence of HCC was assessed. Results. The cumulative incidence of HCC starting from 3 years after the diagnosis of LC in the continuously high ALAT group (annual average over 3 years always > or =80 IU; n=41; Group A) was markedly higher than that in the continuously low ALAT group (always <80 IU; n=48; Group B) (p<0.005) during an observation period of 7.9+/-3.7 years. The incidence of HCC in Group A was 11.8%/year. The odds ratios of developing HCC in Group A and Group C (mixed high and low ALAT levels; n=43) were 5.1-fold and 1.5-fold that of Group B, respectively. A multivariate analysis revealed that the ALAT group was independently associated with HCC development. Conclusions. Continuously high ALAT levels for three successive years following the diagnosis of LC can be predictive of a very high incidence of HCC in Child A HCV-LC patients. Prospective trials using therapeutic approaches aimed at decreasing ALAT levels are necessary in order to confirm a positive impact of ALAT reduction on the incidence of HCC in patients with HCV-LC.

RESUMO

BACKGROUND: Adequate treatment for extremely advanced endometrial cancer is unknown. The purpose of this study was to clarify the prognosis of patients with stage IVB endometrial carcinoma and the validity of treatment. Furthermore, we evaluated whether there was a connection between the prognosis and the site of metastasis. METHODS: The prognoses of 55 patients with stage IVB endometrial carcinoma were studied with reference to the initial treatment method and the metastatic site at the time of the initial treatment. RESULTS: The median survivals of the group of 35 patients who were initially treated with surgery and the group of 10 patients who underwent radiotherapy or chemotherapy as their initial treatment followed by surgery were 11.5 months and 9.5 months, respectively. The residual tumor diameter after surgery was precisely measured in 40 of these 45 patients. The prognosis was significantly better in the patients with a residual tumor diameter of less than 2 cm compared to those with a tumor diameter of 2 cm or greater, and the median survival periods in these two groups were 23.5 months and 11.5 months, respectively (P = 0.027). Furthermore, the prognosis of patients with lung metastasis was significantly better than that of patients with non-lung hematogenous metastasis; the median survival periods of these two groups were 18.5 months and 10.5 months, respectively (P = 0.014). CONCLUSION: For operable patients, surgery as an initial treatment and reduction of the residual tumor size to less than 2 cm appeared to contribute to a better prognosis. In addition, conservative initial treatment and the presence of non-lung hematogenous metastasis were poor prognostic factors.

RESUMO

PURPOSE: To evaluate the prostate and seminal vesicle motion in patients during both simulation and radiotherapy by rectal gas removal. METHODS AND MATERIALS: A total of 34 patients were treated in a whole pelvic radiotherapy (WPRT) arm and 42 patients in a non-WPRT arm. Of the 76 patients, 42 (26 in the non-WPRT arm and 16 in the WPRT arm) were instructed to insert their index finger and wash their rectums to evacuate their rectal gas. In addition to the planning computed tomography scan, three subsequent computed tomography scans were obtained during RT. The organs were outlined on each computed tomography image. Changes in the position of the prostate and seminal vesicles were analyzed using the center of mass (COM) coordinate system. The time trend, overall variations, systematic variations, and random variations were analyzed. RESULTS: The average cross-sectional area in the rectal gas removal group was significantly smaller than in all patients and in the WPRT arm. The vector of the prostate and seminal vesicle displacement for the rectal gas removal group was significantly smaller than in all patients. With rectal gas removal, the 95% confidence limit of the prostate displacement vector was reduced by 2.3 mm in the non-WPRT arm and 2.9 mm in the WPRT arm. The 95% confidence limit of the seminal vesicle displacement vector was reduced by 0.3 mm in the non-WPRT arm and 4.4 mm in the WPRT arm. CONCLUSIONS: Using rectal gas removal, the cross-sectional area could be decreased, resulting in reduced motion and margins for the prostate and seminal vesicles. This is especially important for WPRT patients who require RT to the prostate, seminal vesicles, and pelvic lymph nodes.

RESUMO

There has been an increased incidence of cervical cancer among young women, and they tend to have a poor prognosis due to unknown reasons. We hypothesize growth hormone (GH) receptor (GHR) may be involved in the proliferation of cervical carcinoma, because GH-related neoplasms arise in various organs and the amount of GH secretion may be different according to age. GHR is normally expressed in the cell membrane and cytoplasm, while the nuclear distribution of GHR has been considered to reflect high proliferative activity of cells. We analyzed the subcellular localization of GHR by immunohistochemistry in cervical neoplasms of 55 patients (38.6 +/- 13.9 years old): 33 patients (< 40 years) and 22 patients (>or= 40 years). Nuclear expression of GHR was detected in more than 50% of neoplastic cells present in the tissue samples derived from 20 patients under 40 years (20/33, 61%), whereas less than 25% of neoplastic cells expressed GHR in their nuclei in 17 patients over 40 years (17/22, 77%). In contrast, more than 75% of neoplastic cells showed cytoplasmic GHR expression in the tissues derived from both age groups. Furthermore, the population of cells with nuclear GHR expression was high in the squamous epithelium and the stromal cells of patients under 40, but low in patients over 40. The GH-GHR signal may act at the nuclear level to promote the proliferation of uterine cervical neoplasms in young patients. We suggest the involvement of GHR in progression of uterine cervical carcinoma.

RESUMO

In Japan, The Japanese Association of Clinical Cancer Centers (JACCCs) was established in 1965 by systematizing cancer-treatment-oriented hospitals. The core center of JACCCs is the National Cancer Center in Tokyo. In 1984, JACCCs created The "Improvement for Clinical Cancer Centers in Japan" Study Group (The Study Group) which has subsequently routinely evaluated the effectiveness of the therapy that is provided. In general, the 5-year (relative) survival rate is employed as an indicator of the treatment efficacy. The present survey used the PC software program KAP developed by Chiba Cancer Center in Japan, to calculate 5-year observed survival rates and the 5-year relative survival rates using Ederer II methods. The overall 5-year relative survival rates in patients with stomach (15,353 patients), colon (5,054), rectum (3,695), lung (10,153), breast (11,302) and cervix of the uterus (6,336) were 68.7%, 72.2%, 69.4%, 28.1%, 86.1% and 81.1%, respectively. The survival rates discussed so far are principally observed survival rates. The 5-year relative survival rate for those institutions that specialize in cancer treatment should become an index for Japanese cancer treatment.

RESUMO

"Thenar lancing phlebotomy" is a novel method for the self-collection of blood using a special phlebotomy device for the thenar and a self-collection blood kit. The thenar is punctured with a special lancet, the vein is subjected to automatic avascularization at the wrist and at the same time, a small centrifuge tube, attached to the suction cylinder of the device, is applied to the puncture and the blood is collected by suction. The small centrifuge tube containing the whole blood is centrifuged with a portable centrifugal separator to obtain plasma. In comparison with conventional finger prick phlebotomy, there is less pain and sufficient blood may be obtained. To investigate the accuracy of the method, we collected blood from the antecubital vein of 140 subjects and thenar lancing phlebotomy was simultaneously carried out on the same 140 subjects. The results of many blood tests currently included in medical check-ups were almost identical in the blood samples of both groups, suggesting that this method can be utilized in medical check-ups using self-collected blood sampies.

RESUMO

BACKGROUND: In this study we examined whether histopathological findings, specifically lymphatic vessel invasion identified by an anti-human podoplanin antibody, and several other factors are associated with lymph node metastasis in T1 colorectal cancer. METHODS: We searched PubMed and Cochrane Library, and also handsearched relevant journals, for reports written in English and published between 1998 and 2012, utilizing combination headings, such as 'colorectal cancer,' 'lymph node metastasis,' and 'risk factors.' For the report to be included in our study, the following criteria had to be met: (1) data on the frequency of lymph node metastasis in T1 colorectal cancer in relation to histopathological factors were reported; (2) patients had undergone bowel resection and had histologically diagnosed T1 colorectal cancer; (3) lymphatic vessel invasion was identified by immunohistochemistry with an anti-human podoplanin antibody rather than by hematoxylin and eosin staining; (4) univariate and multivariate analyses were conducted. Studies investigating molecular markers were excluded. The independent predictive factors were confirmed in at least one study included in the meta-analysis in the present systematic review. Microsoft Excel 2013 for Windows was used for the statistical analysis. RESULTS: Initially, 369 publications were identified in the database searches and handsearches, of which five ultimately met all of the inclusion criteria and selected for this systematic review. The meta-analysis revealed that only two factors were significantly associated with T1 colorectal cancer lymph node metastasis: (1) lymphatic vessel invasion identified by an anti-human podoplanin antibody [Mantel-Haenszel odds ratio (OR) 5.19; (95% confidence interval (CI) 3.31-8.15; P = 0.01]; (2) tumor budding (OR 7.45; 95 % CI 4.27-13.02; P = 0.0077). CONCLUSION: Our meta-analysis revealed that lymphatic vessel invasion identified by an anti-human podoplanin antibody and tumor budding were significantly associated with T1 colorectal cancer lymph node metastasis.

RESUMO

BACKGROUND: In Japan, cervical cancer (CC) deaths among women aged <50 years have doubled over the last three decades. Obtaining age-specific CC mortality rates among young women is important for taking measures against CC. Age-adjusted CC mortality rates for all ages are inadequate because of the classification of 'uterine cancer, not otherwise specified' (NOS uterine cancer) and CC mortality rates among elderly women. The aim of the present study was to calculate exact age-specific CC mortality rates in women aged <50 years in Kanagawa, taking into account the impact of NOS uterine cancer. METHODS: Using the Kanagawa Cancer Registry, CC deaths (1975-2012) were analyzed and CC mortality rates (age-adjusted, 20-29, 30-49, and ≥50 years) were calculated. In addition, hospitals were surveyed to reclassify cases of NOS uterine cancer. After reclassification, chronological trends were also analyzed. RESULTS: Age-specific CC mortality rates in Kanagawa and Japan overall showed increasing trends for ages 20-29 (P for trend<0.001) and 30-49 (P for trend<0.001). Rates of NOS uterine cancer death were significantly lower in Kanagawa than in Japan overall (P<0.05), except for patients aged <50 years in 2005-2009 (P=0.159). CONCLUSIONS: The present study revealed concern for CC among Japanese women younger than 50 years. Well-organized CC screening and HPV vaccination should be provided to reduce CC mortality rates for these young women.

RESUMO

We examined whether sustained alleviation of inflammation as monitored by serum alanine aminotransferase (ALT) levels was associated with longer survival in hepatectomized hepatocellular carcinoma (HCC) patients with hepatitis C virus-associated liver cirrhosis (HCV-LC). Thirty-four hepatectomized patients with HCV-LC and HCC as a single nodule, and for whom more than 5 years had elapsed after the hepatectomy, were studied. They had no histologic evidence of portal or hepatic vein invasion. They were subdivided into two groups according to their serum ALT levels in the 2 years after hepatectomy: the low ALT group comprised 13 patients whose serum ALT levels showed a sustained low level below 80 IU, and the high ALT group comprised 21 patients whose serum ALT levels showed several peaks or plateaus above 80 IU. The patients had been followed-up prospectively with frequent ultrasonography and magnetic resonance imaging or computed tomography for recurrence for > 5 years. The survival period, non-recurrence interval and number of recurrences were observed. Recurrences were treated with transcatheter chemoembolization in all cases. The cumulative survival rate in the low ALT group was significantly better than that in the high ALT group (P < 0.05). The 5-year survival in the low ALT group was as high as 92.3% (12 of 13) compared with 33.3% (7 of 21) in the high ALT group (P < 0.05). The cumulative non-recurrence rate in the low ALT group was also significantly better than that in the high ALT group (P < 0.01). The survival period correlated well with the interval until the first recurrence (r = 0.545, P = 0.006). There was a tendency for the number of recurrences in the low ALT group (1.5 +/- 0.4, mean +/- SE) to be fewer than that in the high ALT group (2.2 +/- 0.4), although this was not significant. Sustained alleviation of inflammation, as indicated by low ALT levels, provides a survival advantage mainly due to the longer non-recurrence interval, and possibly because of fewer recurrences, in hepatectomized HCC patients with HCV-LC.
