2023 Japan Society of clinical oncology clinical practice guidelines update for antiemesis.

BACKGROUND: The Japan Society of Clinical Oncology Clinical Practice Guidelines for Antiemesis 2023 was extensively revised to reflect the latest advances in antineoplastic agents, antiemetics, and antineoplastic regimens. This update provides new evidence on the efficacy of antiemetic regimens. METHODS: Guided by the Minds Clinical Practice Guideline Development Manual of 2017, a rigorous approach was used to update the guidelines; a thorough literature search was conducted from January 1, 1990, to December 31, 2020. RESULTS: Comprehensive process resulted in the creation of 13 background questions (BQs), 12 clinical questions (CQs), and three future research questions (FQs). Moreover, the emetic risk classification was also updated. CONCLUSIONS: The primary goal of the present guidelines is to provide comprehensive information and facilitate informed decision-making, regarding antiemetic therapy, for both patients and healthcare providers.

Defining the clinical benefits of adding a neurokinin-1 receptor antagonist to control chemotherapy-induced nausea and vomiting in moderately emetogenic chemotherapy: a systematic review and meta-analysis of the clinical practice guidelines for antiemesis 2023 from the Japan society of clinical oncology.

BACKGROUND: Chemotherapy-induced nausea and vomiting (CINV) commonly affects patient quality of life and the overall effectiveness of chemotherapy. This study aimed to evaluate whether adding neurokinin-1 receptor antagonists (NK1RAs) to 5-hydroxytryptamine-3 receptor antagonists (5-HT3RAs) and corticosteroids provides clinically meaningful benefits in preventing CINV in patients receiving moderately emetogenic chemotherapy (MEC). METHODS: We conducted a systematic review of PubMed, Cochrane Library, and Ichushi-Web to identify clinical studies evaluating NK1RAs combined with 5-HT3RAs and dexamethasone for managing CINV in MEC. The endpoints were complete response (CR), complete control (CC), total control (TC), adverse events, and costs. The data were analyzed using a random effects model. RESULTS: From 142 articles identified, 15 randomized controlled trials (RCTs), involving 4,405 patients, were included in the meta-analysis. Approximately 60% of the patients received carboplatin (CBDCA)-based chemotherapy. The meta-analysis showed that triplet antiemetic prophylaxis with NK1RA was significantly more effective for achieving CR than doublet prophylaxis in each phase. Regarding CC, the triplet antiemetic prophylaxis was significantly more effective than the doublet in the overall (risk difference [RD]: 0.11, 95% confidence interval [CI]: 0.06-0.17) and delayed (RD: 0.08, 95% CI: 0.02-0.13) phases. For TC, no significant differences were observed in any phase. Adding NK1RA did not cause adverse events. CONCLUSIONS: Adding NK1RA to CBDCA-based chemotherapy has shown clinical benefits. However, the clinical benefits of NK1RA-containing regimens for overall MEC have not yet been established and require RCTs that exclusively evaluate MEC regimens other than CBDCA-based chemotherapy.

Efficacy and safety of dexamethasone sparing for the prevention of nausea and vomiting associated with highly emetogenic risk antineoplastic agents: a systematic review and meta-analysis of the Clinical Practice Guidelines for Antiemesis 2023 from the Japan Society of Clinical Oncology.

BACKGROUND: Chemotherapy-induced nausea and vomiting (CINV) are common side effects, classified according to timing and severity. Conventional agents such as dexamethasone are effective but have various side effects. For moderately emetogenic chemotherapy, dexamethasone-sparing antiemetic therapies have been developed to minimize these side effects. This systematic review evaluated the efficacy and safety of dexamethasone-sparing antiemetic therapy for highly emetogenic chemotherapy (HEC). METHODS: We performed a thorough literature search for studies related to dexamethasone-sparing antiemetic therapy with neurokinin-1 antagonists (NK1RA) for HEC using the PubMed, Cochrane Library, and Ichushi-Web databases. A qualitative analysis of the combined data was performed and risk differences with confidence intervals were calculated. RESULTS: Two reviewers independently assessed the 425 records and 12 full-text articles were evaluated for eligibility. Two studies were included in the qualitative and meta-analyses. These studies included anthracycline-cyclophosphamide (AC) regimens and cisplatin-based regimens, with palonosetron as the serotonin receptor antagonist. In the two studies, no difference was found in the prevention of vomiting (delayed complete response). However, non-inferiority was not demonstrated in the subgroup that received cisplatin-containing regimens. Delayed complete control showed different results for nausea prevention; however, there was no significant difference in the meta-analysis. Only one report has shown non-inferiority for delayed total control. Although the strength of evidence for individual outcomes varied, there was no difference in the duration of dexamethasone administration. CONCLUSIONS: This systematic review and meta-analysis revealed that dexamethasone-sparing antiemetic therapy with NK1RA and palonosetron can be used to prevent CINV in HEC, limited to AC combination therapy.

Efficacy and safety of dexamethasone sparing for the prevention of nausea and vomiting associated with moderately emetogenic chemotherapy: a systematic review and meta-analysis of Clinical Practice Guidelines for Antiemesis 2023 from Japan Society of Clinical Oncology.

BACKGROUND: Palonosetron, a second-generation 5-HT3 receptor antagonist (5-HT3RA), is more effective than first-generation 5-HT3RA. Several studies have investigated whether dexamethasone (DEX), when combined with palonosetron as a 5-HT3RA, can be spared in the delayed phase after moderately emetogenic chemotherapy (MEC). In this systematic review, we aimed to determine which between 1- and 3-day DEX administration, when combined with palonosetron, is more useful in patients receiving MEC. METHODS: The PubMed, Cochrane Library, and Ichushi-Web databases were searched for relevant studies published between 1990 and 2020. We included studies that compared the efficacy of 1- and 3-day DEX administration in preventing nausea and vomiting associated with MEC. Outcomes were "prevention of vomiting (complete response rate and no vomiting rate)," "prevention of nausea" (complete control rate, total control rate, no nausea rate, and no clinically significant nausea rate)" in the delayed phase, "prevention of blood glucose level elevation," and "prevention of osteoporosis." RESULTS: Eight studies were included in this systematic review. The no vomiting rate was significantly higher in the 3-day DEX group than in the 1-day DEX group. However, the other efficacy items did not significantly differ between the two groups. Meanwhile, insufficient evidence was obtained for "prevention of blood glucose level elevation" and "prevention of osteoporosis." CONCLUSIONS: No significant differences in most antiemetic effects were found between 1- and 3-day DEX administration. Thus, DEX administration could be shortened from 3 days to 1 day when used in combination with palonosetron.

Non-pharmacological treatments for anticipatory nausea and vomiting during chemotherapy: a systematic review and meta-analysis of the Clinical Practice Guidelines for Antiemesis 2023.

BACKGROUND: Anticipatory chemotherapy-induced nausea and vomiting (CINV) is a conditioned response influenced by the severity and duration of previous emetic responses to chemotherapy. We aimed to evaluate the efficacy of non-pharmacologic interventions for anticipatory CINV among patients with cancer. METHODS: We conducted a systematic search in databases, including PubMed, the Cochrane Library, CINAHL, and Ichushi-Web, from January 1, 1990, to December 31, 2020. Randomized controlled trials, non-randomized designs, observational studies, or case-control studies that utilized non-pharmacological therapies were included. The primary outcomes were anticipatory CINV, with an additional investigation into adverse events and the costs of therapies. The risk-of-bias for each study was assessed using the Cochrane risk-of-bias tool, and meta-analysis was performed using Revman 5.4 software. RESULTS: Of the 107 studies identified, six met the inclusion criteria. Three types of non-pharmacological treatments were identified: systematic desensitization (n = 2), hypnotherapy (n = 2), and yoga therapy (n = 2). Among them, systematic desensitization significantly improved anticipatory CINV as compared to that in the control group (nausea: risk ratio [RR] = 0.60, 95% confidence interval [CI] = 0.49-0.72, p < 0.00001; vomiting: RR = 0.54, 95% CI = 0.32-0.91, p = 0.02). However, heterogeneity in outcome measures precluded meta-analysis for hypnotherapy and yoga. Additionally, most selected studies had a high or unclear risk of bias, and adverse events were not consistently reported. CONCLUSIONS: Our findings suggest that systematic desensitization may effectively reduce anticipatory CINV. However, further research is warranted before implementation in clinical settings.

Optimizing antiemetic treatment for chemotherapy-induced nausea and vomiting in Japan: Update summary of the 2015 Japan Society of Clinical Oncology Clinical Practice Guidelines for Antiemesis.

Patients with cancer should appropriately receive antiemetic therapies against chemotherapy-induced nausea and vomiting (CINV). Antiemetic guidelines play an important role in managing CINV. Accordingly, the first Japanese antiemetic guideline published in 2010 by the Japan Society of Clinical Oncology (JSCO) has considerably aided Japanese medical staff in providing antiemetic therapies across chemotherapy clinics. With the yearly advancements in antiemetic therapies, the Japanese antiemetic guidelines require revisions according to published evidence regarding antiemetic management worldwide. A revised version of the first antiemetic guideline that considered several upcoming evidences had been published online in 2014 (version 1.2), in which several updated descriptions were included. The 2015 JSCO clinical practice guideline for antiemesis (version 2.0) (in Japanese) has addressed clinical antiemetic concerns and includes four major revisions regarding (1) changes in emetogenic risk categorization for anti-cancer agents, (2) olanzapine usage as an antiemetic drug, (3) the steroid-sparing method, and (4) adverse drug reactions of antiemetic agents. We herein present an English update summary for the 2015 JSCO clinical practice guideline for antiemesis (version 2.0).

Temporal hemiarthroplasty for distal femoral osteosarcoma in early childhood: a case report.

BACKGROUND: Prosthetic reconstruction for distal femoral osteosarcoma is challenging for younger children. We herein report a successful case of limb-sparing surgery for a younger patient with distal femoral osteosarcoma requiring osteo-articular resection. CASE PRESENTATION: A 5-year-old girl with high-grade conventional osteosarcoma in the left distal femur underwent a series of surgeries. After three cycles of neoadjuvant chemotherapy, limb-salvage surgery was planned because femoral rotationplasty had been refused. At 6 years and 2 months old, distal femoral resection and temporary spacer insertion using a 7-mm-diameter intramedullary nail and molded polymethylmethacrylate was performed. At 7 years and 8 months old, secondary surgery was performed because the first spacer had been dislocated and the residual femur became atrophic. The distal end of the residual femur was removed by 1 cm, but the periosteum and induced membrane around polymethylmethacrylate was preserved. In order to stabilize the spacer against the tibia, a custom-made ceramic spacer with a smooth straight 8-mm-diameter stem was utilized. The bone-spacer junction was fixed with polymethylmethacrylate and then covered with the preserved periosteum and induced membrane. After surgery, the bone atrophy improved. At 9 years and 7 months old, the second spacer was removed because it had loosened, and the knee joint was reconstructed using a custom-made growing femoral prosthesis with a curved porous 8.5-mm-diameter stem. Cancellous bone tips from the proximal tibia were grafted around the bone-prosthesis junction underneath the induced membrane. At 10 years and 5 months old, the patient was able to walk unsupported and a radiograph showed further thickening of the cortex of the residual femur without any stress shielding. Although having 5 cm of limb length discrepancy, the patient and her mother were satisfied with the function. The MSTS score was 24 out of 30 points. Repeated limb length extensions are planned. CONCLUSIONS: This case report provides an example of limb-salvage surgery after distal femoral resection in a small child. The use of a temporary spacer utilizing partial cementation and preservation of the periosteum and induced membrane appears to afford a viable limb-salvage option after distal femoral resection for younger children.

Acute Myocardial Infarction in an Adolescent Receiving Anagrelide for Essential Thrombocythemia with Underlying Persistent Coronary Endothelial Dysfunction.

Essential thrombocythemia (ET) is a Philadelphia chromosome-negative myeloproliferative disorder that is characterized by the overproduction of platelets and a marked increase in the numbers of mature megakaryocytes present in the bone marrow. Thrombohemorrhagic disorders are major morbidities of ET, especially those with mutations in the gene encoding Janus kinase 2 (JAK2). In this study, we report the case of an 18-year-old patient with ET carrying JAK2 mutation who developed acute ST-elevation myocardial infarction (STEMI) 5 months after a commencement of anagrelide. Coronary endothelial dysfunction confirmed by positive acetylcholine provocation test lasted a year after the occurrence of STEMI. Furthermore, intracoronary imaging using optical coherence tomography demonstrated non-atheromatous intimal fibrosis possibly due to chronic endothelial damage. The coronary pathologies reflected chronic change potentially associated with properties of ET and JAK2 mutation in addition to hyperviscosity. These observations suggest that the side effect of anagrelide in our patient was considered causative, while underlying chronic endothelial dysfunction and adverse endothelial remodeling may be predisposing factors to his fatal cardiovascular events.

[Pathological Findings of Chronic Effects Observed in the Kidneys Exposed to Antineoplastic Agents in Two Adolescent Patients].

Cisplatin and ifosfamide are well-known nephrotoxic agents that can cause acute and chronic glomerular and/or tubular toxicity. We examined 2 adolescent patients who were receiving cisplatin and ifosfamide treatments. Pathological findings of patient 1 showed acute tubular necrosis-like patchy injury. Tubulointerstitial nephrosis and glomerular sclerosing were revealed in patient 2. These findings were consistent with the known damages induced by cisplatin and ifosfamide. Proteinuria and mild decline of eGFR were noticed after more than 10 months after the completion of the treatment. It is important to monitor such consequences in long-term follow up. Adult based medical services are required for childhood and adolescent cancer survivors.

Non-Invasive Pulmonary Capillary Wedge Pressure Assessment on Speckle Tracking Echocardiography as a Predictor of New-Onset Non-Valvular Atrial Fibrillation　- Four-Year Prospective Study (NIPAF Study).

BACKGROUND: Although new-onset atrial fibrillation (AF) increases with ageing, the prediction of new-onset AF is complicated. We previously reported that pulmonary capillary wedge pressure (ePCWP) estimated by the combination of left atrial volume index (LAVI) and active left atrial emptying function (aLAEF) had a strong relationship with PCWP on catheterization (r=0.92): ePCWP=10.8-12.4×log (aLAEF/minimum LAVI). We sought to determine the usefulness of ePCWP to predict new-onset AF. Methods and Results: We measured LAVI, aLAEF and ePCWP on speckle tracking echocardiography (STE) in 566 consecutive elderly patients (72±6 years) without a history of AF. A total of 63 patients (73±6 years) developed electrocardiographically confirmed AF during a mean follow-up period of 50 months. Baseline aLAEF was significantly lower in patients with than without new-onset AF (17.9±6.5 vs. 28.2±7.5%), whereas ePCWP was significantly higher (14.8±3.7 vs. 10.3±3.1 mmHg). In multivariate logistic regression analysis, ePCWP and aLAEF were strong independent predictors of AF. Using ePCWP >13 mmHg or aLAEF ≤22% on univariate Cox regression analysis, the HR for new-onset AF were 3.53 (95% CI: 1.68-7.44, P<0.001) and 4.06 (95% CI: 1.90-8.65, P<0.001), respectively. By combining these 2 criteria (>13 mmHg and ≤22%), the HR increased to 11.84 (95% CI: 6.85-20.5, P<0.001). CONCLUSIONS: ePCWP and aLAEF measured on STE are useful predictors of new-onset AF. ePCWP provides added value for risk stratification of new-onset AF.

Evaluation of systolic and diastolic properties of hypertensive heart failure using speckle-tracking echocardiography with high volume rates.

Left ventricular (LV) properties in hypertension (HTN) could be deteriorated by pressure overload, especially in endocardium, resulting in hypertensive heart failure (HHF). We sought to noninvasively examine LV systolic and diastolic functions at three myocardial layers in HTN and elucidate features of HHF by speckle-tracking echocardiography (STE) with high volume rates. We examined normotensive controls (n = 54), HTN patients without LV hypertrophy (LVH) (n = 50), and HTN patients with LVH (n = 40) and HHF patients (n = 45). The HHF group was divided into two subgroups based on their LVEF (20 heart failure with preserved ejection fraction: HFpEF and 25 heart failure with reduced ejection fraction: HFrEF). LV layer systolic function was assessed by strain rate during systole. Pulmonary capillary wedge pressure (PCWP) was estimated (ePCWP) using kinetics-tracking index (KT index) that we previously reported. HTN patients with LVH had a significant deterioration of systolic and diastolic properties compared with normotensive controls in the absence of a significant reduction in LVEF. Patients with HHF had further deterioration of systolic and diastolic properties compared with HTN patients with LVH. LV strain at entire myocardium and ePCWP in HFrEF was deteriorated compared with those in HFpEF. Deterioration of LV layer SR was more typical during systole, isovolumic relaxation, and early diastole compared with control. LV dilation was independently associated with LVEF (r = -0.48, p < 0.001) and ePCWP (r = 0.47, p < 0.001), and LVH (LV mass index) was independently associated with E/e' (r = 0.37, p = 0.025), LVEF (r = -0.44, p < 0.001), and ePCWP (r = 0.67, p < 0.001). LV layer analysis by STE could detect subtle impairments in systolic function before the deterioration of LVEF in patients with HTN. The ePCWP that was estimated using KT index was the independent factor associated with HHF. The ePCWP may be useful to noninvasively detect the early stage of HHF.

Estimated pulmonary capillary wedge pressure assessed by speckle tracking echocardiography predicts successful ablation in paroxysmal atrial fibrillation.

BACKGROUND: Atrial fibrillation (AF) is associated with left atrial (LA) remodeling caused by pressure and/or volume (LAV) overload. Increased pulmonary capillary wedge pressure (PCWP) represents LA pressure overload. We recently reported that pulmonary capillary wedge pressure (ePCWP) can be estimated by the kinetics-tracking (KT) index that combines LA function and volume using speckle tracking echocardiography (STE), and has a strong correlation with PCWP measured by right heart catheterization (r = 0.92). Therefore, we hypothesized that ePCWP is the best echocardiographic predictor of successful AF ablation. METHODS: We enrolled 137 patients with paroxysmal AF (age: 61 ± 10 years) who underwent pulmonary vein isolation. We measured LAV index, LA emptying function (EF) and LA stiffness during sinus rhythm before ablation using STE. PCWP was noninvasively estimated by STE as we previously reported. Parameters were compared between a group with AF recurrence (n = 30, age: 59 ± 11 years) and a group with successful ablation (sinus rhythm maintained for >1 year) (n = 107, age 61 ± 11 years). RESULTS: The ePCWP was correlated with PCWP measured by right heart catheterization (r = 0.76, p < 0.01). Compared with the non-recurrence group (n = 107, age: 61 ± 11), the AF recurrence group had significantly increased ePCWP (10.6 ± 3.5 vs 14.6 ± 2.9 mmHg, p < 0.01), minimum LAV index (29 ± 12 ml/m(2) vs 37 ± 14 ml/m(2), p < 0.01) and LA stiffness (0.47 ± 0.33 vs 0.83 ± 0.59, p < 0.01), but lower total LA EF (44 ± 11% vs 39 ± 13%, p < 0.01) before ablation. In multivariate logistic regression analysis, ePCWP was the most significant independent predictor of successful ablation. Using 13 mmHg of PCWP as the optimal cutoff value, the sensitivity and specificity for successful ablation were 73 and 77% (area under the curve = 0.81), respectively. CONCLUSION: The ePCWP that is measured by the combination of LA function and volume before ablation was a better predictor of the successful ablation compared with LA function and volume separately. The ePCWP estimated by STE is useful to predict the successful ablation in paroxysmal AF, and could be useful to improve candidate selection for AF ablation.

Japanese Society of Clinical Oncology clinical practice guidelines 2010 for antiemesis in oncology: executive summary.

The purpose of this article is to disseminate the standard of antiemetic therapy for Japanese clinical oncologists. On the basis of the Appraisal of Guidelines for Research and Evaluation II instrument, which reflects evidence-based clinical practice guidelines, a working group of the Japanese Society of Clinical Oncology (JSCO) reviewed clinical practice guidelines for antiemesis and performed a systematic review of evidence-based domestic practice guidelines for antiemetic therapy in Japan. In addition, because health-insurance systems in Japan are different from those in other countries, a consensus was reached regarding standard treatments for chemotherapy that induce nausea and vomiting. Current evidence was collected by use of MEDLINE, from materials from meetings of the American Society of Clinical Oncology National Comprehensive Cancer Network, and from European Society of Medical Oncology/Multinational Association of Supportive Care in Cancer guidelines for antiemesis. Initially, 21 clinical questions (CQ) were selected on the basis of CQs from other guidelines. Patients treated with highly emetic agents should receive a serotonin (5-hydroxytryptamine; 5HT3) receptor antagonist, dexamethasone, and a neurokinin 1 receptor antagonist. For patients with moderate emetic risk, 5HT3 receptor antagonists and dexamethasone were recommended, whereas for those receiving chemotherapy with low emetic risk dexamethasone only is recommended. Patients receiving high-emetic-risk radiation therapy should also receive a 5HT3 receptor antagonist. In this paper the 2010 JSCO clinical practice guidelines for antiemesis are presented in English; they reveal high concordance of Japanese medical circumstances with other antiemetic guidelines that are similarly based on evidence.

Anti-inflammatory and morphologic effects of pitavastatin on carotid arteries and thoracic aorta evaluated by integrated backscatter trans-esophageal ultrasound and PET/CT: a prospective randomized comparative study with pravastatin (EPICENTRE study).

BACKGROUND: We sought to evaluate the effects of a strong lipophilic statin (pitavastatin) on plaque components and morphology assessed by transesophageal echocardiography (TEE) and transthoracic echocardiography (TTE), as well as plaque inflammation assessed by 18F-fluorodeoxyglucose (FDG) PET/CT in the thoracic aorta and the carotid artery. Furthermore, we compared the effects of pitavastatin with those of mild hydrophilic statin (pravastatin). METHODS: We examined atherosclerotic plaques in the thoracic aorta by TEE and those in the carotid artery by integrated backscatter (IBS)-TTE and PET/CT. We identified the target plaque, where there was macrophage infiltration and inflammation, by strong FDG uptake in the thoracic aorta and carotid arteries and measured maximum standard uptake values (max SUV) by PET/CT. We measured the intima-media thickness (IMT) and the corrected IBS (cIBS) values in the intima-media complex by TEE and TTE at the same site of FDG accumulation by PET/CT. RESULTS: Patients were randomly divided into two treatment groups: a pitavastatin group (PI group: n =10, 68.4 ± 5.1 years) and a pravastatin group (PR group: n =10, 63.9 ± 11.2 years). The same examinations were performed after six months at the same site in each patient. We used calculated target-to-background ratio (TBR) to measure max SUV of plaques and evaluated percent change of TBR. There was no significant difference in low density lipoprotein-cholesterol, TBR, IMT and cIBS values in plaques at baseline between the PI and PR groups. After treatment, there was greater improvement in TBR, cIBS values and IMT in the PI group than the PR group. CONCLUSIONS: The pravastatin treatment was less effective on plaque inflammation than pitavastatin treatment. This trend was the same in the carotid arteries and the thoracic aorta. Pitavastatin not only improved the atherosis as measured by IMT and cIBS values but also attenuated inflammation of plaques as measured by max SUV at the same site. The present study indicated that pitavastatin has stronger effects on the regression and stabilization of plaques in the thoracic aorta and carotid arteries compared with pravastatin.

[The survey for anti-emetic guideline by using questioner].

BACKGROUND: Japan Society of Clinical Oncology published a guideline for anti-emetic therapy two years ago. This guideline was a first evidence based guideline of anti-emetic treatment for the patients who received chemotherapy in Japan. To investigate a current situation of anti-emetic treatment in Japan, we analyzed the data from nationwide questionnaire. MATERIAL: Questionnaire analysis; From June 2012 to August 2012, we gave 24 questionnaires on the Japan Society of Clinical Oncology Website and collected the response from the member of 5 major academic oncology societies. The questionnaires included degree of recognition, penetration, usefulness, problems and user type of medial stuff for the anti-emetic guideline published by (JSCO). RESULTS: Questionnaire; 1,529 medical stuff responded to our questionnaire. 1,308 (85.5%) stuffs recognized JSCO guidelines, 586 (51%) had regard for guideline and 489 (42.6%) referred to the guideline. 899 (78.3%) changed their practice in clinic to recommended practice by the guideline. But 385 (33.5%) complained high medical cost of recommended anti-emetic therapy. CONCLUSIONS: Degree of recognition and penetration of our guideline for anti-emetic therapy were very high in Japan.

Technical refinement in living-donor liver transplantation for hepatoblastoma with main portal vein tumor thrombosis - a pullout technique.

We present a case of a two-yr-old boy diagnosed with HBT with complete main PVTT. HBT was located in the bilateral lobe with PVTT involving the confluence of the SMV and the SpV. Cisplatin-based neoadjuvant chemotherapy was delivered; main tumor shrank and AFP levels decreased to below one hundredth. However, PVTT remained in the bilateral portal branches to the main trunk of PV. We describe the technical details of the portal venous tumor thrombectomy that was succeeded by a LDLT. The patient remained healthy 2.5 yr after LDLT, showing good patency of the PV with no evidence of recurrence of tumor.

Comparative effect of candesartan and amlodipine, and effect of switching from valsartan, losartan, telmisartan and olmesartan to candesartan, on early morning hypertension and heart rate.

Early morning hypertension and a high heart rate are risk factors for cardiovascular disease. The DOHSAM study was designed to evaluate the effect of candesartan on early morning blood pressure (BP) and heart rate in hypertensives. We used a prospective, randomized, open-label design. Protocol 1: Patients with early morning BP more than 135/85 mmHg who were not on any antihypertensive drug or on candesartan were given amlodipine 2.5 mg/day (amlodipine group, n = 22) or added candesartan 4 mg/day (candesartan group, n = 36). Candesartan or amlodipine was added when BP did not fall lower than 135/85 mmHg. Protocol 2: Early morning hypertensives who were on other angiotensin receptor blockers (ARBs) (n = 50) such as valsartan, losartan, telmisartan and olmesartan were switched to candesartan. Early morning BP significantly decreased in the candesartan group compared with the amlodipine group 9 and 12 months after treatment. Switching other ARBs except for olmesartan to candesartan significantly decreased early morning systolic and diastolic BP 3, 6, 9 and 12 months after treatment. Heart rate in the office significantly decreased by switching to candesartan 6, 9 and 12 months after treatment. In conclusion, candesartan significantly decreased early morning hypertension more than amlodipine or other ARBs except olmesartan in early morning hypertensives.
