RESUMO
Germline pathogenic variants of BRCA1 or BRCA2 cause hereditary breast and ovarian cancer syndromes. The present study investigated the participants' understanding and awareness of germline BRCA1/2 pathogenic variants before genetic counseling, the expectations and obstacles for genetic testing from the perspective of participants and their families, and their attitudes towards genetic testing after counseling. In this single-country, multicenter, non-interventional, patient-reported outcome study, untested cancer patients and their families who visited genetic counseling clinics or who wanted to receive pre-test genetic counseling were eligible to fill in the questionnaire after pre-test counseling for germline BRCA1/2 testing. Demographic information, clinical characteristics, and information collected from the questionnaires, including the understanding of BRCA1/2 pathogenic variants before genetic counseling, understanding of BRCA1/2 pathogenic variants and feelings after genetic counseling, willingness to share results of genetic testing with family, and willingness to receive genetic testing, were summarized using descriptive statistics. A total of 88 participants were enrolled. The proportion of slight understanding of BRCA1/2 pathogenic variants increased from 11.4% to 67.0%, and the proportion of full understanding increased from 0% to 8.0%. After genetic counseling, most participants were willing to undergo genetic testing (87.5%) and share the results with their families (96.6%). The main factors that may affect participants' willingness to undergo BRCA1/2 testing were management (61.2%) and testing costs (25.9%). After pre-test counseling, there was a high acceptance of BRCA1/2 testing and in-family information sharing in Taiwanese patients with cancer and their families, which may serve as a reference for implementing genetic counseling in Taiwan.

BACKGROUND: Laparoscopic procedure has inherent merits of smaller incisions, better cosmesis, less postoperative pain, and earlier recovery. In the current study, we presented our method of purely laparoscopic feeding jejunostomy and compared its results with that of conventional open approach. METHODS: We retrospectively reviewed our patients from 2012 to 2019 who had received either laparoscopic jejunostomy (LJ, n = 29) or open ones (OJ, n = 94) in Chang Gung Memorial Hospital, Linkou. Peri-operative data and postoperative outcomes were analyzed. RESULTS: In the current study, we employed 3-0 Vicryl, instead of V-loc barbed sutures, for laparoscopic jejunostomy. The mean operative duration of LJ group was about 30 min longer than the OJ group (159 ± 57.2 mins vs 128 ± 34.6 mins; P = 0.001). There were no intraoperative complications reported in both groups. The patients in the LJ group suffered significantly less postoperative pain than in the OJ group (mean NRS 2.03 ± 0.9 vs. 2.79 ± 1.2; P = 0.002). The majority of patients in both groups received early enteral nutrition (< 48 h) after the operation (86.2% vs. 74.5%; P = 0.143). CONCLUSIONS: Our study demonstrated that purely laparoscopic feeding jejunostomy is a safe and feasible procedure with less postoperative pain and excellent postoperative outcome. It also provides surgeons opportunities to enhance intracorporeal suture techniques.

BACKGROUND: The association between immune-related adverse events (irAEs) and survival outcomes in patients with advanced melanoma receiving therapy with immune checkpoint inhibitors (ICIs) has not been well established, particularly in Asian melanoma. METHODS: We retrospectively reviewed 49 melanoma patients undergoing therapy with ICIs (anti-PD-1 monotherapy), and analyzed the correlation between irAEs and clinical outcomes including progression-free survival (PFS) and overall survival (OS). RESULTS: Overall, the patients who experienced grade 1-2 irAEs had longer PFS (median PFS, 4.6 vs. 2.5 months; HR, 0.52; 95% CI: 0.27-0.98; p = 0.042) and OS (median OS, 15.2 vs. 5.7 months; HR, 0.50; 95% CI: 0.24-1.02; p = 0.058) than the patients who did not experience irAEs. Regarding the type of irAE, the patients with either skin/vitiligo or endocrine irAEs showed better PFS (median PFS, 6.1 vs. 2.7 months; HR, 0.40, 95% CI: 0.21-0.74; p = 0.003) and OS (median OS, 18.7 vs. 4.5 months; HR, 0.34, 95% CI: 0.17-0.69, p = 0.003) than patients without any of these irAEs. CONCLUSIONS: Melanoma patients undergoing anti-PD-1 monotherapy and experiencing mild-to-moderate irAEs (grade 1-2), particularly skin (vitiligo)/endocrine irAEs had favorable survival outcomes. Therefore, the association between irAEs and the clinical outcomes in melanoma patients undergoing anti-PD-1 ICIs may be severity and type dependent.

The circadian rhythm regulates blood pressure and maintains fluid and electrolyte homeostasis with central and peripheral clock. However, the role of circadian rhythm in the pathogenesis of tubulointerstitial fibrosis remains unclear. Here, we found that the amplitudes of circadian rhythm oscillation in kidneys significantly increased after unilateral ureteral obstruction. In mice that are deficient in the circadian gene Clock, renal fibrosis and renal parenchymal damage were significantly worse after ureteral obstruction. CLOCK-deficient mice showed increased synthesis of collagen, increased oxidative stress, and greater transforming growth factor-ß (TGF-ß) expression. TGF-ß mRNA expression oscillated with the circadian rhythms under the control of CLOCK-BMAL1 heterodimers. The expression of cyclooxygenase 2 was significantly higher in kidneys from CLOCK-deficient mice with ureteral obstruction. Treatment with a cyclooxygenase 2 inhibitor celecoxib significantly improved renal fibrosis in CLOCK-deficient mice. Taken together, these data establish the importance of the circadian rhythm in tubulointerstitial fibrosis and suggest CLOCK/TGF-ß signaling as a novel therapeutic target of cyclooxygenase inhibition.

PURPOSE: To assess the correlation of coronary calcium score (CS) obtained by artificial intelligence (AI) with those obtained by electrocardiography gated standard cardiac computed tomography (CCT) and nongated chest computed tomography (ChCT) with different reconstruction kernels. PATIENTS AND METHODS: Seventy-six patients received standard CCT and ChCT simultaneously. We compared CS obtained in 4 groups: CS CCT , by the traditional method from standard CCT, 25 cm field of view, 3 mm slice thickness, and kernel filter convolution 12 (FC12); CS AICCT , by AI from the standard CCT; CS ChCTsoft , by AI from the non-gated CCT, 40 cm field of view, 3 mm slice thickness, and a soft kernel FC02; and CS ChCTsharp , by AI from CCT image with same parameters for CS ChCTsoft except for using a sharp kernel FC56. Statistical analyses included Spearman rank correlation coefficient (ρ), intraclass correlation (ICC), Bland-Altman plots, and weighted kappa analysis (κ). RESULTS: The CS AICCT was consistent with CS CCT (ρ = 0.994 and ICC of 1.00, P < 0.001) with excellent agreement with respect to cardiovascular (CV) risk categories of the Agatston score (κ = 1.000). The correlation between CS ChCTsoft and CS ChCTsharp was good (ρ = 0.912, 0.963 and ICC = 0.929, 0.948, respectively, P < 0.001) with a tendency of underestimation (Bland-Altman mean difference and 95% upper and lower limits of agreements were 329.1 [-798.9 to 1457] and 335.3 [-651.9 to 1322], respectively). The CV risk category agreement between CS ChCTsoft and CS ChCTsharp was moderate (κ = 0.556 and 0.537, respectively). CONCLUSIONS: There was an excellent correlation between CS CCT and CS AICCT , with excellent agreement between CV risk categories. There was also a good correlation between CS CCT and CS obtained by ChCT albeit with a tendency for underestimation and moderate accuracy in terms of CV risk assessment.

This study aimed to evaluate the effect of Astragalus polysaccharides (PG2) on reducing chemotherapy-induced fatigue (CIF) and toxicity, thereby encouraging compliance to chemotherapy. This was a randomized, placebo-controlled, phase 2 study. Patients with stage II/III early breast cancer planning to undergo adjuvant anthracycline-based chemotherapy were randomly assigned to receive PG2 500 mg or placebo on days 1, 3, and 8 every 21 days. The fatigue global score (FGS) was assessed using the brief fatigue inventory (BFI)-Taiwan. The Breast Cancer-Specific Module of the European Organization for Research and Treatment of Cancer Quality of Life Questionnaires-Core30 evaluated the health-related quality of life during the first four cycles of adjuvant chemotherapy. Overall, 66 eligible patients were equally randomized into the PG2 and placebo groups between March 01, 2018, and March 09, 2021. The mean change in the FGS and fatigue intensity did not significantly differ between both groups. However, the FGS and fatigue intensity were less aggravated in the first four cycles in the premenopausal-PG2 group than in the placebo group. Our study concluded PG2 combined with adjuvant chemotherapy can reduce CIF, insomnia, the negative effect on future perspectives, and improve global health status, especially for premenopausal patients with breast cancer. Trial registration number: NCT03314805 registered on 19/10/2017.

To overcome the drawbacks of high solubility and instability of polyoxometalates (POMs) in aqueous solution and to expand their application in the electrocatalytic reduction of CO2 (ECR), we assemble sandwich-type POMs, K10[(PW9O34)2M4(H2O)2] (M = Mn, Ni, Zn, shortened as P2W18M4), into the hexagonal channel of a porphyrin-based metal-organic framework (MOF) PCN-222 to form P2W18M4@PCN-222 composites. Their ECR behavior displays polyoxoanion-dependent activity. P2W18Mn4@PCN-222 demonstrates a faradaic efficiency of 72.6% for the CO product (FECO), more than four times that of PCN-222 (FECO = 18.1%), and exhibits exceptional electrochemical stability over 36 h. P2W18Ni4@PCN-222 and P2W18Zn4@PCN-222 slightly increase (26.9%) and decrease (3.2%) in FECO, respectively. We combine the results with density functional theory (DFT) calculations to help understand the intrinsic reasons which reveals that the rate-determining step (RDS) reaction energy of P2W18Mn4@PCN-222 and P2W18Ni4@PCN-222 is significantly reduced compared to that of PCN-222. It is different in P2W18Zn4@PCN-222. Frontier molecular orbitals electron distribution results hint at directional electron transfer from P2W18Mn4/P2W18Ni4 to the porphyrin ring active center in PCN-222, promoting the electro-reduction of CO2 activity. By contrast, P2W18Zn4 may accumulate electrons from PCN-222, thus facilitating the hydrogen evolution reaction (HER). This work reveals the critical role of sandwich-type POMs in manipulating the electron transfer pathway during the electrocatalytic process. Our findings would broaden the scope of POM applications in electrochemical carbon dioxide reduction.
RESUMO
Esophageal cancer is a deadly disease, and neoadjuvant chemoradiotherapy can improve patient survival, particularly for patients achieving a pathological complete response (ypCR). However, existing imaging methods struggle to accurately predict ypCR. This study explores computer-aided detection methods, considering both imaging data and radiotherapy dose variations to enhance prediction accuracy. It involved patients with node-positive esophageal squamous cell carcinoma undergoing neoadjuvant chemoradiotherapy and surgery, with data collected from 2014 to 2017, randomly split into five subsets for 5-fold cross-validation. The algorithm DCRNet, an advanced version of OCRNet, integrates RT dose distribution into dose contextual representations (DCR), combining dose and pixel representation with ten soft regions. Among the 80 enrolled patients (mean age 55.68 years, primarily male, with stage III disease and middle-part lesions), the ypCR rate was 28.75%, showing no significant demographic or disease differences between the ypCR and non-ypCR groups. Among the three summarization methods, the maximum value across the CTV method produced the best results with an AUC of 0.928. The HRNetV2p model with DCR performed the best among the four backbone models tested, with an AUC of 0.928 (95% CI, 0.884-0.972) based on 5-fold cross-validation, showing significant improvement compared to other models. This underscores DCR-equipped models' superior AUC outcomes. The study highlights the potential of dose-guided deep learning in ypCR prediction, necessitating larger, multicenter studies to validate the results.
RESUMO
To avoid the agglomeration of iron NPs and improve the dispersion of Fe SAs, we employed a mixed-ligand strategy to regulate the iron content in PCN-224(ZnxFey) and PCN-222(ZnxFey). Thanks to the sublimation of Zn and the Kirkendall effect, uniform dispersions of Fe SAs with 1.04-1.06 wt% were obtained in the pyrolysis products Zn0.5Fe0.5-N-C-224 and Zn0.5Fe0.5-N-C-222 with excellent CO2 â CO activity, super-stability, and recyclability.
RESUMO
Background: Colorectal cancer (CRC) is the third leading cause of cancer-related deaths in Taiwan. Chronic obstructive pulmonary disease (COPD) is associated with CRC mortality in several population-based studies. However, this effect of COPD on CRC shows no difference in some studies and remains unclear in Taiwan's population. Methods: We conducted a retrospective cohort study using Taiwan's nationwide database. Patients newly diagnosed with CRC were identified from 2007 to 2012 via the Taiwan Cancer Registry dataset and linked to the National Health Insurance research database to obtain their medical records. Propensity score matching (PSM) was applied at a ratio of 1:2 in COPD and non-COPD patients with CRC. The 5-year overall survival (OS) was analyzed using the Cox regression method. Results: This study included 43,249 patients with CRC, reduced to 13,707 patients after PSM. OS was lower in the COPD group than in the non-COPD group. The adjusted hazard ratio (aHR) for COPD was 1.26 (95% confidence interval (CI), 1.19-1.33). Moreover, patients with CRC plus preexisting COPD showed a higher mortality risk in all stage CRC subgroup analysis. Conclusions: In this 5-year retrospective cohort study, patients with CRC and preexisting COPD had a higher mortality risk than those without preexisting COPD, suggesting these patients need more attention during treatment and follow-up.

BACKGROUND: The optimal definitive chemotherapy regimen during concurrent chemoradiotherapy (CRT) for patients with advanced esophageal squamous cell carcinoma (ESCC) remains unclear because of conflicting evidence. This study aimed to compare the effectiveness of taxane-based chemotherapy with that of conventional cisplatin plus 5-fluorouracil (PF) as the chemotherapy regimen in definitive CRT for ESCC. PATIENTS AND METHODS: This retrospective study included patients with ESCC who received paclitaxel plus carboplatin (PC) or PF during definitive CRT between May 2012 and February 2015 in a medical center in Taiwan. Survival outcomes were compared after adjustment for risk factors. RESULTS: Overall, 229 patients were evaluated. Patients in the PC group had an objective response rate of 71.1% compared with the 51.4% of the PF group (p = 0.016). The PC group showed a significantly longer progression-free survival (PFS, p = 0.002) and overall survival (OS, p = 0.019) than the PF group. Salvage surgery also helped prolong both the PFS and OS (p < 0001). Sex (male vs. female, HR, 1.831; 95% CI, 1.016-3.303), clinical stage (HR, 1.282; 95% CI, 1.069-1.537), accumulative radiation dose (≥41.4 Gy vs. <41.4 Gy; HR, 0.640; 95% CI, 0.413-0.993), salvage surgery (yes vs. no, HR: 0.412, 95% CI: 0.298-0.570), and regimen (PF vs. PC; HR, 1.514; 95% CI, 1.109-2.067) were independent prognostic factors for cancer mortality. CONCLUSION: Compared with the PF regimen, the PC regimen for definitive CRT yielded significantly increased response rates and longer survival times; therefore, the PC regimen may be preferable for chemotherapy for definitive CRT in patients with advanced ESCC.

Background: Immune checkpoint inhibitors (ICIs) have significantly changed the current approach to cancer treatment. Although the use of ICIs has become the standard of care for advanced melanoma, reports of ICI use among Asian populations with melanoma are limited. Therefore, we conducted this retrospective study to assess the efficacy and safety of ICI use in Taiwanese patients. Patients: Patients with histologically confirmed melanoma treated with ICIs at Linkou Chang Gung Memorial Hospital from January 2014 to July 2019 were retrospectively reviewed. Univariant and multivariant analyses were performed to identify possible prognostic factors. Results: Among 80 patients, 45 were treatment-naïve (56.3%), and 35 received prior systemic drugs other than ICIs. Regarding treatment regimens, patients were treated with ipilimumab (n = 9), nivolumab (n = 33), pembrolizumab (n = 16), or combination drugs (n = 22). Nine patients achieved either a complete (n = 2) or partial (n = 7) response and 13 patients were stable, with a resulting response rate of 11.3% and disease control rate of 27.5%. As of the last follow-up in January 2020, patients treated with combination drugs had longer median progression-free survival (PFS) of 5.6 (95% confidence interval [CI]: 1.6-9.6) months than nivolumab (2.9 months, 95% CI: 1.9-3.9 months), pembrolizumab (3.2 months, 95% CI: 2.6-3.8 months), and ipilimumab (2.6 months, 95% CI: 2.4-2.8 months; p = 0.011). No significant differences in overall survival (OS) among the four regimens (p = 0.891) were noted. In the multivariate analysis, combination treatment, disease control, and performance ≤ 1 were independent prognostic factors for PFS. Liver metastases and no disease control were independent unfavorable prognostic factors for OS. The most common factor was skin toxicity (45%), followed by endocrine toxicity (18.8%). Patients undergoing combination treatment experienced more frequent and serious adverse events than patients undergoing monotherapy. Conclusion: ICIs demonstrated efficacy and safety in Taiwanese patients with melanoma. Combination treatment showed the greatest efficacy, but this was also accompanied by greater toxicity among the four regimens. In addition, we identified important prognostic factors, such as liver metastases, performance status, and tumor response, for both PFS and OS. These findings could provide physicians with more information to justify clinical outcomes observed in Asian patients with advanced melanoma.
RESUMO
Pazopanib-a multitargeted tyrosine kinase inhibitor with prominent antiangiogenic effects-has shown promise in the treatment of soft-tissue sarcomas. Hyperthermia has been also applied as an adjunctive treatment to chemotherapy for these malignancies. Here, we show that pazopanib and hyperthermia act synergistically in inhibiting uterine leiomyosarcoma (LMS) cell growth. Compared with either treatment alone, the combination of pazopanib and hyperthermia exerted the highest antitumor activity in a xenograft model. Mechanistically, we found that combined treatment with pazopanib and hyperthermia inhibited histone acetyltransferase 1 (HAT1) expression in LMS cells. The Clock element on the HAT1 promoter was critical for pazopanib- and hyperthermia-induced HAT1 downregulation. Inhibition of HAT1-either by pazopanib and hyperthermia or through HAT1 silencing-was mediated by suppression of Clock. Accordingly, Clock protein reconstitution rescued both HAT1 levels and HAT1-mediated histone acetylation. Immunohistochemistry revealed a higher expression of HAT1 in uterine LMS than in leiomyomas (p = 0.007), with high HAT1 expression levels being associated with poor clinical outcomes (p = 0.007). We conclude that pazopanib and hyperthermia exert synergistic effects against LMS growth by inhibiting HAT1. Further preclinical studies on HAT1 as a potential drug target in uterine LMS are warranted, especially in combination with hyperthermia. KEY MESSAGES: Pazopanib and hyperthermia inhibit the growth of leiomyosarcoma. Their combined use inhibits HAT1 expression in leiomyosarcoma cells. The promoter Clock element is required for HAT1 downregulation. HAT1 expression is higher in leiomyosarcoma than in leiomyomas. An increased HAT1 expression is associated with poor clinical outcomes.

With the increasing use of targeted anticancer drugs and immunotherapies, there have been a substantial number of reports concerning life-threatening severe cutaneous adverse reactions (SCARs), including Stevens-Johnson syndrome (SJS), toxic epidermal necrolysis (TEN), drug rash with eosinophilia and systemic symptoms, drug-induced hypersensitivity syndrome, and acute generalized exanthematous pustulosis. Although the potential risks and characteristics for targeted anticancer agent- and immunotherapy-induced SCAR were not well understood, these serious adverse reactions usually result in morbidity and sequela. As a treatment guideline for this devastating condition is still unavailable, prompt withdrawal of causative drugs is believed to be a priority of patient management. In this review, we outline distinct types of SCARs caused by targeted anticancer therapies and immunotherapies. Also, we discuss the clinical course, latency, concomitant medication, tolerability of rechallenge or alternatives, tumor response, and mortality associated with these devastating conditions. Imatinib, vemurafenib, and rituximab were the top three offending medications that most commonly caused SJS/TEN, while EGFR inhibitors were the group of drugs that most frequently induced SJS/TEN. For drug rash with eosinophilia and systemic symptoms/drug-induced hypersensitivity syndrome and acute generalized exanthematous pustulosis, imatinib was also the most common offending drug. Additionally, we delineated 10 SCAR cases related to innovative immunotherapies, including PD1 and CTLA4 inhibitors. There was a wide range of latency periods: 5.5-91 days (median). Only eight of 16 reported patients with SCAR showed clinical responses. Targeted anticancer drugs and immunotherapies can lead to lethal SCAR (14 deceased patients were identified as suffering from SJS/TEN). The mortality rate of TEN was high: up to 52.4%. The information compiled herein will serve as a solid foundation to formulate ideas for early recognition of SCAR and to discontinue offending drugs for better management.
RESUMO
This study aimed to assess the utility of the Eastern Cooperative Oncology Group (ECOG) performance scale assessments on days 1 and 8 of palliative care, as well as scale change between these assessments, as prognostic tools for patients with terminally ill cancer. A total of 2392 patients with terminally ill cancer who received palliative care between January 2006 and December 2011 at a single medical center were analyzed. Our study showed that the ECOG scale is a useful prognostic tool to predict life expectancy in patients with terminally ill cancer. The ECOG scale assessments at different time points under palliative care were independent predictors for overall survival. The combined ECOG scale assessments on days 1 and 8 predicted survival more precisely than using day 1 ECOG scale assessment alone.

Bone marrow metastasis (BMM) in patients with solid cancers is indicative of advanced-stage disease with a poor prognosis. The clinical features and outcomes remain unclear. We aimed to develop a scoring system to predict survival in these patients to help with clinical decision making. A total of 165 adult patients diagnosed with solid cancers and BMM between 2000 and 2014 were selected as the derivation cohort. A risk model was developed using multivariate logistic regression from the derivation cohort and a marrow metastases prognostic score (MMPS) was generated. An independent cohort of 156 patients from 3 other hospitals was selected using the same recruiting criteria to validate the MMPS as a predictor of survival. The MMPS was calculated based on 4 independent prognostic variables: the Eastern Cooperative Oncology Group performance scale, site of cancer, platelet count, and neutrophil-to-lymphocyte ratio. Patients in both the derivation and validation cohorts were stratified into good, intermediate, and poor prognostic groups based on their MMPS. The median survival in each risk group of the derivation cohort was 241, 58, and 11 days for the good, intermediate, and poor prognostic groups, respectively, and 305, 65, and 9 days, respectively, in the validation cohort. The c-statistic values for prediction of mortality at 3, 6, and 12 months were significantly higher for the MMPS than for the Eastern Cooperative Oncology Group performance scale in both cohorts. We developed a risk model that accurately predicted survival in adult patients with solid cancers and BMM. This scoring system may help patients and clinicians with treatment decisions.
