In the context of cittaslow (slow city), this research attempts to examine the effects of memorable tourism experience (MTE) on tourist satisfaction and revisiting intention. The research used a structured questionnaire and collected 605 valid responses from tourists that visited Sanyi Cittaslow. Analyses of the measurement model and structural model by AMOS 22.0 were used to find the associations between each MTE dimension and satisfaction, and revisit intention. Test results revealed that all MTE dimensions are predictors of tourist satisfaction, among which knowledge and involvement are the strongest predictors; satisfaction is the strongest predictor for revisiting and is the mediator for the associations of most MTE dimensions and revisiting. Since the cittaslow movement was closely related to sustainable tourism, research finding from this research provide a good reference with evidence for the promotion of cittaslow through MTE creation.

Advanced breast cancer (ABC) has become a chronic disease. In such a situation, an effective therapy with low toxicities and economically acceptable is needed. Metronomic vinorelbine (mVNR) has been proved to be effective on the control of MBC. The aim of this study is to evaluate the efficacy and safety of mVNR as the salvage therapy for patients with ABC. Oral vinorelbine (VNR) was administered at 70 mg/m2, fractionated on days 1, 3, and 5, for 3 weeks on and 1 week off. Once the mVNR was combined with trastuzumab, or was combined with bevacizumab, the schedule was changed to 2 weeks on and 1 week off. Clinical data of patients with ABC who had received treatment with mVNR and tumor characteristics were collected and analyzed. From Mar. 2013 to Dec, 2020, there were 90 patients with ABC received mVNR. The overall response rate was 53.3% and overall disease control rate (DCR) was 78.9% in this study, including 4 (4.4%) cases reached complete response, 44 (48.9%) cases reached partial response and 23 (25.6%) cases were table disease. The median time to treatment failure (TTF) of the Lumina A patients was 13.3 months, Lumina B patients was 9.1 months, Her-2 enrich patients was 8.9 months, and triple negative breast cancer (TNBC) patients was 5.6 months. Median overall survival time for Lumina A, Lumina B, Her-2 enrich and TNBC were 54.6 months, 53.3 months, 59.5 months and 24.5 months separately. Side effects were minimal and manageable. Metronomic VNR can be an effective treatment for ABC either works as a switch maintenance or salvage therapy. In combination with target therapy or hormonal therapy, mVNR can further improve TTF and DCR with minimal toxicities. Further study should focus on the optimal dosage, schedule and combination regimen.

Background: Melatonin, produced by the pineal gland, is known for its antioxidant, oncostatic, and anti-inflammatory properties. However, studies on serum melatonin levels in different cancer types have yielded conflicting results, and little is known about the clinical significance of serum melatonin in oral squamous cell carcinoma (OSCC) in the Southern Asian population. Therefore, we explored its role in OSCC in this study. Methods: A total of 67 male OSCC patients and 78 healthy controls were enrolled in this case–control study. The serum levels of melatonin were determined by enzyme-linked immunosorbent assay (ELISA) and compared between the two groups. Results: The serum melatonin levels were significantly lower in OSCC patients compared with healthy controls (mean ± standard deviation, 15.0 ± 4.6 vs. 18.5 ± 11.8 pg/mL, p = 0.02). In the subgroup of age less than 55 years (mean age of OSCC), OSCC patients had a significantly decreased melatonin level than healthy controls (mean melatonin, 15.7 ± 12.6 vs. 20.8 ± 3.9 pg/mL, p = 0.02). Decreased serum melatonin (odds ratio (OR): 0.95, 95%CI: 0.91–0.99), alcohol consumption (OR: 29.02, 95%CI: 11.68–72.16), betel quid chewing (OR:136.44, 95%CI: 39.17–475.27), and cigarette smoking (OR:29.48, 95%CI: 11.06–78.60) all increased the risk of OSCC under univariate analyses of logistic regression. Betel quid chewing (OR: 45.98, 95%CI: 10.34–204.49) and cigarette smoking (OR:6.94, 95%CI: 1.60–30.16) were the independent risk factors for OSCC in Taiwan. In addition, a negative correlation between age and melatonin level was observed in healthy controls (Pearson r = −0.24, p = 0.03). However, the negative correlation was lost in patients with OSCC. Melatonin concentration had no association with the severity of OSCC. Conclusion: Overall, our study provides evidence that serum melatonin levels decreased in OSCC patients in Taiwan and the decreased level is much significant in young populations and suggests that the decreased melatonin was associated with OSCC, especially in young populations. Further studies are warranted to investigate whether melatonin can be a useful non-invasive screening tool for OSCC.

Background: Hepatitis C virus (HCV) in diffuse large B-cell lymphoma (DLBCL) is associated with a higher prevalence and distinctive clinical characteristics and outcomes. Methods: A retrospective analysis of adult DLBCL patients from 2011 to 2015 was studied. Results: A total of 206 adult DLBCL were enrolled with 22 (10.7%) HCV-positive patients. Compared to HCV-negative patients, the HCV-positive group had a poor performance status (p = 0.011), lower platelet count (p = 0.029), and higher spleen and liver involvement incidences (liver involvement, p = 0.027, spleen involvement, p = 0.026), and they received fewer cycles of chemotherapy significantly due to morbidity and mortality (p = 0.048). Overall survival was shorter in HCV-positive DLBCL (25.3 months in HCV-positive vs. not reached (NR), p = 0.049). With multivariate analysis, poor performance status (p &lt, 0.001), advanced stage (p &lt, 0.001), less chemotherapy cycles (p &lt, 0.001), and the presence of liver toxicity (p = 0.001) contributed to poor OS in DLBCL. Among HCV-positive DLBCL, the severity of liver fibrosis was the main risk factor related to death. Conclusion: Inferior survival of HCV-positive DLBCL was observed and associated with poor performance status, higher numbers of complications, and intolerance of treatment, leading to fewer therapy. Therefore, anti-HCV therapy, such as direct-acting antiviral agents, might benefit these patients in the future.

Simple Summary Systemic therapies for advanced biliarty tract cancers (BTC) are limited. The combination of gemcitabine with cisplatin (GC) has been the standard first-line treatment for advanced BTC from 2010 until now. In order to improve therapeutic effect, especially response rate, we added a novel schedule and dosage of bevacizumab to standard GC regimen. In our real world date, we found this regimen could increase the overall response rate to 50.0%, and side effects were managable. For patients with advanced BTC, especially whose tumors need rapid response to treatment, our regimen can provide an alternative choice. Abstract Background: Biliary tract cancer (BTC) is a heterogenous collection of biliary tract cancer at different primary sites, and the prognosis of advanced BTC is dismal. Systemic chemotherapy with gemcitabine and cisplatin (GC) has been the reference regimen since 2010. How to improve therapeutic effects of GC regimen is an urgent mission at present. Methods: Bevacizumab with a reduced dosage and modified schedule (10 mg/Kg/triweekly, 1 day before GS at the first 2 cycles) was combined with standard GC for patients with advanced BTC. Tumor response was assessed using Response Evaluation Criteria in Solid Tumors version 1.1 every 2 months. Kaplan–Meier curves were estimated for time-to-treatment failure (TTF), progression-free survival (PFS) and overall survival (OS). Result: A total of thirty cases of advanced BTC accepted this treatment, and the overall response rate (ORR) was 50.0%, and the disease control rate was 80.0% for all patients. The median TTF was 5.8 months, the median PFS was 8.4 months, and the median OS was 13.6 months. Most responses were noted at the first evaluation. Adverse effects (AEs) were mostly tolerable. Conclusions: After modifying the schedule, adding bevacizumab to a traditional GC regimen could increase the ORR with a shorter time-to-response, a better PFS and OS than GC alone but without the addition of AE. This regimen can be applied to patients with advanced BTC, especially those who are with a big tumor burden and who need a rapid response.

Perivascular epithelioid cell tumors (PEComas) are uncommon mesenchymal tumors characterized by the presence of both myogenic and melanocytic markers, and huge soft tissue PEComas are even rarer. With low prevalence, there has been no common consensus therapy in the past and the treatment response varies. As the aberrant activation of mammalian target of rapamycin (mTOR) pathway has been revealed in previous studies, mTOR inhibitor is now one of the treatment choices in malignant PEComa. Here we report a case of a 50-year-old man with identified 16-cm soft tissue mass at left flank with multiple lung and bone metastases, revealing typical immunohistochemical and pathological of malignant PEComa. Sirolimus was applied in an adjuvant setting, however interval progression in size was observed. To find the optimal dose of mTOR inhibitors, we performed a literature review for dosing strategy as well.

Background Hepatitis B virus (HBV) reactivation with a hepatitis flare is a common complication in lymphoma patients treated with immunotherapy and/or chemotherapy. Anti-HBV prophylaxis is suggested for non-Hodgkin lymphoma (NHL) patients undergoing rituximab therapy, even those with resolved HBV infection. Since anti-HBV prophylaxis for patients with resolved HBV infection is not covered by national health insurance in Taiwan, a proportion of these patients receive no prophylaxis. In addition, late HBV reactivation has emerged as a new issue in recent reports, and no consensus has been reached for the optimal duration of antiviral prophylaxis. Thus, the aim of our study was to investigate the incidence and outcomes of HBV reactivation in NHL patients in a real-world setting and to study the frequency of late HBV reactivation. Materials Non-Hodgkin lymphoma patients who received rituximab and/or chemotherapy at our institute between January 2011 and December 2015 and who were hepatitis B surface antigen (HBsAg)- or hepatitis B core antibody (HBcAb)-positive were reviewed retrospectively. Results A total of 388 patients were screened between January 2011 and December 2015. In total, 196 patients were excluded because HBsAg was not assessed, HBcAb was negative or not assessed, or they were not treated with immunosuppressive therapy. Finally, the retrospective study included 62 HBsAg-positive NHL patients and 130 NHL patients with resolved HBV infection (HBsAg-negative and HBcAb-positive). During a median 30.5-month follow-up period, seven patients experienced HBV reactivation, five of whom had a hepatitis flare. The incidence of HBV reactivation did not significantly differ between the HBsAg-positive patients and the resolved HBV infection population without anti-HBV prophylaxis (4.8% vs. 3.1%, P = 0.683). All patients with HBV reactivation were exposed to rituximab. Notably, late HBV reactivation was not uncommon (two of seven patients with HBV reactivation events, 28.6%). Hepatitis B virus reactivation did not influence the patients’ overall survival. An age ≥65 years and an advanced disease stage were independent risk factors for poorer overall survival. Conclusion The incidence of HBV reactivation was similar between the HBsAg-positive patients with antiviral prophylaxis and the resolved HBV infection population without anti-HBV prophylaxis. All HBV reactivation events occurred in NHL patients exposed to rituximab. Late reactivation was not uncommon. The duration of regular liver function monitoring for more than 1 year after immunosuppressive therapy or after withdrawal of prophylactic antiviral therapy should be prolonged. Determining the exact optimal duration of anti-HBV prophylaxis is warranted in a future prospective study for NHL patients treated with rituximab-containing therapy.

Hepatitis B reactivation is a common complication in lymphoma patients under immunosuppressive treatment with potentially serious and life-threating consequences. In this review, we discuss the basis of chronic Hepatitis B virus (HBV) infection, the definition and risk factors for HBV reactivation. We overview the management of HBV reactivation based on virological status and immunosuppressive regimen risk stratification. We also highlight and update information about the HBV reactivation in lymphoma patients under novel agent treatment, including newer monoclonal antibodies, small molecule inhibitors, and even chimeric antigen receptor T-cell immunotherapy.

Background: Fluoropyrimidine- and platinum-based doublet regimen is the standard treatment of adjuvant chemotherapy (AC) for gastric cancer (GC). Our study aims to compare S1 with doublet regimens as AC in patients with advanced GC after radical surgery with D2 dissection. Methods: Patients who were diagnosed with GC and underwent a curative surgery with D2 dissection followed by AC were enrolled into our study. A propensity score matching analysis was performed to reduce the selection bias. Kaplan&ndash, Meier curves were estimated for recurrence-free survival (RFS) and overall survival (OS). Cox regression models were conducted for survival. Results: After propensity sore matching, 64 patients with S1 and 64 patients with doublet regimens were identified. The median RFS (p = 0.355) and OS (p = 0.309) were both insignificant between S1 and ST. Cox regression analysis demonstrated that pathologic stage and lymph node ratio (LNR) were independently correlated with survival. Patients were then stratified into low risk and high risk groups. The median RFS (p &lt, 0.001) and OS (p &lt, 0.001) had significant differences between low risk and high risk. In the high-risk group, doublet regimens were strongly associated with survival (p = 0.020) as compared with S1. While in the low-risk group, doublet regimen and S1 did not have statistically different survival benefits. Conclusions: Our study demonstrated that doublet regimens are superior to S1 in high-risk groups, and that survival outcomes are similar between doublet regimens and S1 in low-risk groups. Our prognostic model might have clinical implications for AC.

This study aimed to investigate the treatment strategy, prognostic factors, and risk factors of early death in elderly patients (age ≥ 65 years) with diffuse large B-cell lymphoma (DLBCL) in the rituximab era. Data from elderly patients diagnosed with DLBCL between 2008 and 2014 were collected for analysis. Patients who were younger and had a better performance status were more likely to receive intensive frontline treatment. The median progression-free survival (PFS) and overall survival were 15 and 21 months, respectively. Anthracycline-containing chemotherapy achieved a higher remission rate and showed a trend towards better overall survival but a higher risk of severe neutropenia. Multivariate analysis revealed that very old age (≥81 years), a high-risk age-adjusted international prognostic index (aaIPI) score, and bone marrow involvement were associated with poorer PFS and overall survival. Progression of lymphoma was the major cause of death in the study population. In addition, approximately 25% of patients died within 120 days of being diagnosed. The risk factors for early mortality included very old age, a high-risk aaIPI score, and bone marrow involvement. The appearance of symptoms or signs of tumour lysis syndrome at diagnosis was associated with a trend towards early death.

Prostate cancer typically metastasizes to bones and regional lymph nodes. Generalized lymphadenopathy is a rare manifestation of metastatic prostate cancer. We report a case of prostate cancer in a 65-year-old male with initial presentation of generalized lymphadenopathy and no urinary symptoms. Lymph node biopsy revealed metastatic adenocarcinoma, and immunohistochemical staining was positive for prostate-specific antigen (PSA) compatible with a prostatic origin. Directed biopsy confirmed that the tumor originated in the prostate. Therefore, the prostate should be considered a possible origin of metastatic adenocarcinoma in men, and presentations consistent with generalized lymphadenopathy cannot exclude a diagnosis of prostate cancer.

Nonadherence is common in patients with chronic myeloid leukemia (CML) and leads to treatment failure and poor outcomes. Side effects due to treatment are also common in patients with CML. However, no study has investigated the link between side effects and medication adherence for patients with CML in Taiwan. Therefore, the aim of our study was to explore the influence of side effects on medication adherence in Taiwanese patients with CML. CML in chronic-phase patients treated with breakpoint cluster region-Abelson murine leukemia viral oncogene homolog 1 tyrosine kinase inhibitors were recruited. We designed a questionnaire to collect baseline patient information, medication adherence (measured using the 8-item Morisky Medication Adherence Scale), and side effects. Clinical outcomes were assessed by the 3-month early molecular response rate and the 12-month major molecular response rate. Statistical comparisons of different parameters between adherent and nonadherent groups were conducted. Fifty-eight patients were enrolled in this study, and 31% of them had poor adherence. The lack of information about treatment and medication was the major reason for poor medication adherence. Patients who were younger and unmarried were prone to poor adherence. The occurrence of side effects carried no statistically significant influence on adherence. Poor adherence resulted in a poor treatment response (lower 3-month early molecular response rate and lower 12-month major molecular response rate). Poor adherence is common in Taiwanese patients with CML. The main reason for a decrease in the adherence rate is the lack of comprehensive information about treatment and medication, particularly in young and single population. The next urgent step is to educate patients about their treatment and management of side effects to improve adherence and treatment outcome for patients with CML in Taiwan.

Background The purpose of this study was to investigate the association between previous exposure to statins and the risk of non-Hodgkin lymphoma (NHL). Methods This nationwide population-based case–control study was conducted using the National Health Insurance Research Database of Taiwan. The NHL group consisted of the patients with a first-time diagnosis of NHL between 2005 and 2008. The cases of the control group were pair-matched to the NHL group according to sex, year of birth and date of NHL diagnosis (index date). The statin administration data from both groups were retrospectively collected from the index date to January 1, 1996. The cumulative defined daily dose (cDDD) was estimated to evaluate the statin exposure. Adjusted odds ratios (ORs) and 95% confidence intervals (CIs) were estimated using multivariate logistic regression. Results The study population was composed of 1715 NHL patients and 16942 control subjects. The analysis revealed that previous statin administration was associated with a reduced risk of subsequent NHL with an adjusted OR of 0.52 (95% CI, 0.43–0.62). Additionally, there was a dose-response relationship between statin administration and the risk of NHL. The adjusted ORs were 0.63 (95% CI, 0.46–0.86), 0.58 (95% CI, 0.42–0.79), 0.51 (95% CI, 0.38–0.67), and 0.36 (95% CI, 0.24–0.53) for the subjects with statin administrations of fewer than 28, 28 to 90, 91 to 365, and more than 365 cDDDs, respectively, relative to the subjects without any statin administration. Conclusions The results of this study suggest that previous statin administration is associated with a lower risk of subsequent NHL. As statins are widely used medications, the magnitude of the risk reduction may have a substantial influence on public health. Further studies to confirm our findings are warranted.

Deriving from “Parasite Single” proposed by Yamada (1997), “parasites” in this study is redefined as those who live with and financially rely on their parents in terms of living expenses after school graduation. The current study adopts the logit model and utilizes the data from the 1999 to 2000 Taiwan Panel Study of Family Dynamics to investigate the determinants of “parasites”. The finding reveals that gender, age, marital status, and the value of filial piety are significantly different between parasites and non-parasites. Moreover, gender, monthly income, age and marital status are determinants of the probability of being parasites.

Thromboembolism is a complication of hematopoietic stem cell transplant. However, a literature search showed no previous reports of cerebral infarction during the thrombocytopenic stage after hematopoietic stem cell transplant. A 35-year-old woman with acute lymphoblastic leukemia (precursor B-cell type) was treated with hematopoietic stem cell transplant after induction and consolidation chemotherapy. On day 2 after transplant, she was unconscious, and had urinary incontinence and left hemiplegia. A computed tomography scan of the brain showed an acute ischemic infarct in the right middle cerebral artery region and an old infarct at the left thalamus without atherosclerosis. Factor VIII level was elevated (190%; normal range, 60% to 150%). She was treated with rehabilitation and low-dose aspirin. At 6 months after transplant, the leukemia remained in remission and she had no further thromboembolic events. This case suggests that prudent treatment of patients who have hematopoietic stem cell transplant may include monitoring for thromboembolism and testing factor VIII level before transplant.

Dear Editor, Donor cell leukemia (DCL), a relapse of leukemia derived from donor origin, is a rare complication of hematopoietic stem cell transplant (HSCT), and the etiology is still equivocal. Herein, we reported a rare case of donor cell-derived acute promyelocytic leukemia (APML) 3 years after HLA-identical allogeneic HSCT from his sister with literature review. A 52-year-old male was diagnosed of myelodysplastic syndrome, refractory anemia with excess blasts-1 in April 2010. Bone marrow aspiration revealed dysgranulopoietic change and dyserythropoiesis with increased blast cell up to 7.6 % with normal karyotype. He had supportive care and received allogeneic peripheral blood HSCT in December 2010, from his sex-mismatched HLA-identical sister. The donor was healthy without any underlying disorder in pretransplant survey. Total body irradiation (2Gy bid for 3 days) and cyclophosphamide (60 mg/kg for 2 days) were used as conditioning regimen with cyclosporine and methotrexate (on day 1, 3, 6, and 11) for GVHD prophylaxis. A total of 10.06× 10 CD34+cells/kg was infused. He suffered from acute GVHD (grade 2) at day +28 and cytomegalovirus (CMV) infection at day +42 after HSCT. CMV was controlled by gancyclovir 400 mg for 14 days, and the acute GVHD subsided after cyclosporine therapy. Cytogenetic and chimerism studies by PCR amplification of short tandem repeats (STR) revealed full donor chimerism 1month after the transplant and at the follow-up 1 year later. The patient got stable condition for 3 years with limited chronic GVHD over oral cavity, skin, and liver with cyclosporine therapy. Unfortunately, progressive thrombocytopenia was noted in January 2014. Bonemarrow examination showedAPMLwith marked infiltration with heavily granulated promyelocytes containing Auer roods. Molecular study by RT-PCR was positive for PML/RARA transcript, whichwas not found from donor sample and patient’s samples before and after HSCT (Fig. 1) [1]. Chromosome study showed t(15,17)(q22:q21) translocation in all donor cells (46,XX), and chimerism study was still in full donor chimerism. Donor cell-derived APML was diagnosed, and the patient received induction therapy with all-trans-retinoic-acid and idarubicin. Unfortunately, patient suffered from febrile neutropenia and died of septic shock 10 days after induction. The development of true DCL after allogeneic HSCT is rare with the first case reported in 1971 [2]. Since then, several cases had been reported, but the true incidence is difficult to assess [3–5]. A large survey from the European Group for Blood andMarrowTransplantation (EBMT) reported 14 cases from 10,489 transplantations performed during a 21-year period [6]. Our case with cytogenetic and chimerism studies H.

The outcome of allotransplants in patients with chronic -phase (CP) chronic myeloid leukemia (CML) who progressed to accelerated phase (AP) or blast phase (BP) following imatinib failure, especially those without preceding suboptimal response, remains unclear.One hundred and five patients with newly-diagnosed CML-CP were retrospectively reviewed. Sixty-six patients received first-line imatinib therapy, 26 received interferon followed by imatinib, and 13 received front-line allotransplants.No significant differences were found in overall survival (p=0.57) and blast-free survival (p=0.25) between different first-line therapies. Among 66 imatinib-treated patients, 18 (27.3%) developed imatinib failure, 14 (21.2%) progressed to AP/BP, including eight without preceding suboptimal response. Compared to front-line allotransplant, patients with imatinib failure had a significantly worse overall survival after allotransplants (p=0.015), mainly due to an increase of treatment-related mortality.Early recognition of imatinib-treated patients who should receive an allotransplant is important rather than waiting until imatinib failure with disease progression.

The case report describes a woman who has an acute psychosis episode during the second course of trimethoprim/sulfamethoxazole therapy, after having an allogeneic hematopoietic stem cell transplant that favored a dose-related effect of this adverse effect.
