RESUMO

BACKGROUND/OBJECTIVES: Liposomal irinotecan plus 5-fluorouracil and leucovorin (nal-IRI + 5-FU/LV) provides survival benefits for metastatic pancreatic adenocarcinoma (mPDAC) refractory to gemcitabine-based treatment, mainly gemcitabine plus nab-paclitaxel (GA), in current practice. Gemcitabine plus S-1 (GS) is another commonly administered first-line regimen before nab-paclitaxel reimbursement; however, the efficacy and safety of nal-IRI + 5-FU/LV for mPDAC after failed GS treatment has not been reported and was therefore explored in this study. METHODS: In total, 177 patients with mPDAC received first-line GS or GA treatment, followed by second-line nal-IRI + 5-FU/LV treatment (identified from a multicenter retrospective cohort in Taiwan from 2018 to 2020); 85 and 92 patients were allocated to the GS and GA groups, respectively. Overall survival (OS), time-to-treatment failure (TTF), and adverse events were compared between the two groups. RESULTS: The baseline characteristics of the two groups were generally similar; however, a higher median age (67 versus 62 years, p < 0.001) and fewer liver metastases (52% versus 78%, p < 0.001) were observed in the GS versus GA group. The median OS was 15.0 and 15.9 months in the GS and GA groups, respectively (p = 0.58). The TTF (3.1 versus 2.8 months, p = 0.36) and OS (7.6 versus 6.7 months, p = 0.83) after nal-IRI treatment were similar between the two groups. More patients in the GS group developed mucositis during nal-IRI treatment (15% versus 4%, p = 0.02). CONCLUSIONS: The efficacy of second-line nal-IRI +5-FU/LV treatment was unaffected by prior S-1 exposure. GS followed by nal-IRI treatment is an alternative treatment sequence for patients with mPDAC.

RESUMO

BACKGROUND: Few studies have examined the preoperative risks and healthcare costs related to free flap revision in hypopharyngeal cancer (HPC) patients. METHODS: A 20-year retrospective case-control study was conducted using the Chang Gung Research Database, focusing on HPC patients who underwent tumor excision and free flap reconstruction from January 1, 2001, to December 31, 2019. The impacts of clinical variables on the need for re-exploration due to free flap complications were assessed using logistic regression. The direct and indirect effects of these complications on medical costs were evaluated by causal mediation analysis. RESULTS: Among 348 patients studied, 43 (12.4%) developed complications requiring re-exploration. Lower preoperative albumin levels significantly increased the risk of complications (OR 2.45, 95% CI 1.12-5.35), especially in older and previously irradiated patients. Causal mediation analysis revealed that these complications explained 11.4% of the effect on increased hospitalization costs, after controlling for confounders. CONCLUSIONS: Lower preoperative albumin levels in HPC patients are associated with a higher risk of microvascular free flap complications and elevated healthcare costs, underscoring the need for enhanced nutritional support before surgery in this population.

RESUMO

BACKGROUND: Research studies have demonstrated that Midkine (MDK) can influence the expression and activity of Renin-angiotensin system (RAS) components. Angiotensin II is involved in tumor growth and angiogenesis in different cancers. We previously observed Angiotensin II receptor blockers (ARBs) improve the survival rates of patients with oral cancers. These findings have prompted us to investigate whether MDK can influence the RAS pathway, mainly through its association with angiotensin II type 1 receptor (AT1R), which contributes to the observed poor prognosis in head and neck squamous cell carcinoma (HNSCC) patients. METHODS: MDK and AT1R expressions were examined in 150 HNSCC patients post-operation by immunohistochemical staining between 1 January 2010 and 31 December 2016. We tested the over-expression and silencing of MDK to evaluate the AT1R expression and functional biological assays in HNSCC cell lines HSC-3 and SAS. RESULTS: Positive expression of MDK is correlated with positive AT1R expression. MDK predicted poor NSCC patients' survival. Silencing MDK could suppress AT1R and pAKT expression and reduce the growth, migration, and invasion of HNSCC cells. ARB also inhibits MDK stimulating HNSCC cell proliferation. Overexpression of MDK could upregulate AT1R and pAKT. CONCLUSIONS: MDK is an independent prognostic factor of HNSCC post-operation, and AT1R regulates HNSCC cell growth, invasion, and migration. Positive MDK and AT1R expressions are highly correlated. Mechanistically, the interaction between MDK and AT1R is crucial for MDK-mediated cell viability, and inhibiting AT1R can effectively counteract or abolish these effects. Furthermore, MDK exerts a regulatory role in the expression of AT1R, as well as in the growth and motility of HNSCC cells. These findings highlight the involvement of the interaction between MDK, AT1R, and the pAkt signaling pathways in HNSCC cell viability growth.

RESUMO

Leptin is a crucial regulator of metabolism and energy homeostasis in mammals. Many studies have investigated the impacts of leptin on human cancers, such as proliferation and metastasis. However, the mechanisms underlying leptin-mediated regulation of lipid metabolism in nasopharyngeal carcinoma (NPC) remain incompletely understood. In the current study, leptin downregulation ameliorated lipid accumulation, triglyceride, and cholesterol levels. Mechanistically, diminished leptin by siRNA not only inhibited sterol regulatory element-binding protein 1 (SREBP1), a master regulator of lipid metabolism, at the mRNA and protein levels, but also reduced SREBP1 downstream target expressions, such as fatty acid synthase (FASN) and stearoyl-CoA desaturase-1 (SCD1), in NPC cells. In addition, leptin expression could modulate the promoter activity of SREBP1. We also found that pharmacological inhibition of poly-ADP ribose polymerase-γ (PPAR-γ) resulted in increased SREBP1 expression in leptin-depleted NPC cells. Functionally, SREBP1 overexpression overcame the effects of leptin-silencing attenuated triglyceride level, cholesterol level and cell survival in NPC cells. Taken together, our results demonstrate that leptin is an important regulator of lipid metabolism in NPC cells and might could be a potential therapeutic target for treatment of NPC patients.

RESUMO

Otolaryngology (also known as ear, nose, and throat (ENT)) diseases can be significantly affected by the level of sex hormones, which indicates that sex differences affect the manifestation, pathophysiology, and outcomes of these diseases. Recently, increasing evidence has suggested that proinflammatory responses in ENT diseases are linked to the level of sex hormones. The sex hormone receptors are present on a wide variety of immune cells; therefore, it is evident that they play crucial roles in regulating the immune system and hence affect the disease progression of ENT diseases. In this review, we focus on how sex hormones, particularly estrogens, regulate ENT diseases, such as chronic rhinosinusitis, vocal fold polyps, thyroid cancer, Sjögren's syndrome, and head and neck cancers, from the perspectives of inflammatory responses and specialized proresolving mediator-driven resolution. This paper aims to clarify why considering sex differences in the field of basic and medical research on otolaryngology is a key component to successful therapy for both males and females in the future.

RESUMO

Pancreatic cancer (PC) is a highly lethal malignancy due to the cancer routinely being diagnosed late and having a limited response to chemotherapy. Pancreatic ductal adenocarcinoma (PDAC) is the most common form of pancreatic malignant tumor, representing more than 85% of all pancreatic cancers. In the present study, we characterized the phenotypes of concomitant P53 and APC mutations in pancreatic neoplasms driven by the oncogene KRAS in genetically modified mice (GEMM). In this GEMM setting, APC haploinsufficiency coupled with P53 deletion and KRASG12D activation resulted in an earlier appearance of pancreatic intraepithelial neoplasia (PanIN) lesions and progressed rapidly to highly invasive and metastatic PDAC. Through a microarray analysis of murine PDAC cells derived from our APC-deficient PDAC model, we observed that APC loss leads to upregulated CD34 expression in PDAC. CD34 is a member of a family of single-pass transmembrane proteins and is selectively expressed in hematopoietic progenitor cells, vascular endothelial cells, interstitial precursor cells, and various interstitial tumor cells. However, the functional roles of CD34 in pancreatic cancer remain unclear. Thus, in this study, we explored the mechanisms regarding how CD34 promotes the deterioration of pancreatic malignancy. Our results demonstrated that the increased expression of CD34 induced by APC inactivation promotes the invasion and migration of PDAC cells, which may relate to PDAC metastasis in vivo. Collectively, our study provides first-line evidence to delineate the association between CD34 and the APC/Wnt pathway in PDAC, and reveals the potential roles of CD34 in PDAC progression.

RESUMO

BACKGROUND: Post-surgical prognosis is usually poor for combined hepatocellular cholangiocarcinoma (CHCC-CC), a rare primary liver cancer. Although midkine (MK) is a prognostic biomarker for several known cancers, it is not known whether it can be used as such in resectable CHCC-CC. This study examined whether MK expression can predict recurrence and survival in patients with resectable CHCC-CC. METHODS: We retrospectively enrolled 52 patients with resectable CHCC-CC who had received curative hepatic resections. MK expression was assessed in post-surgical immunohistochemical studies of specimens in paraffin blocks. Clinical outcomes were analyzed from medical records. RESULTS: Two-year disease-free and three-year overall survival rates were 42.1% and 44.6%. MK was expressed in 30 patients. Univariate analysis showed patients positively expressing MK had a significantly poorer 2-year disease free and three-year overall survival. Multivariate analysis found positive MK expression independently predicted recurrence. CONCLUSIONS: Positive expression of MK predicts poor prognosis in patients with resectable CHCC-CC.

RESUMO

BACKGROUND: This study investigated the therapeutic benefit of radical resection (SRR) for clinical T4b oral cavity squamous cell carcinoma (OSCC) with partial or complete response after radical chemoradiotherapy (CRT). METHODS: At the authors' institution, 79 patients with newly diagnosed non-metastatic T4b OSCC were treated with CRT from January 2009 to December 2014. All of them were irradiated using intensity-modulated radiotherapy (IMRT), with a radical dose (median 70 Gy; range 66-76 Gy) in the gross tumor area. Of the 65 cases achieving partial or complete response after CRT, 33 were treated further with SRR and 32 with adjuvant chemotherapy or observation. The locoregional control (LRC), overall survival (OS), and cancer-free survival (CFS) rates were compared between the two groups. RESULTS: The 3-year LRC, OS, and CFS rates were respectively 72.3, 75.1, and 72.6 % in the SRR group compared with 32.8, 47.7, and 44.3 % in the non-SRR group (p < 0.05). Multivariate analysis showed that SRR was the only statistically significant prognostic factor related to LRC, OS, and CFS. For those with SRR, pathologic downstaging was observed in 27 cases (81.8 %). Perioperative flap failure was observed in three cases (9.2 %) and neck wound necrosis in four cases (12.1 %). CONCLUSIONS: For T4b OSCC, incorporating SRR in the therapy is technically safe and has survival benefit, with a significant response after CRT applied by IMRT, with a radical dose in the gross tumor area.

RESUMO

BACKGROUND: Smoking and betel nut chewing are well-known risk factors for head and neck squamous cell carcinoma (HNSCC). Smoking is also a strong prognosticator for patients with locally advanced HNSCC receiving induction chemotherapy. Smoking with or without betel nut chewing is a common practice in Asia. However, little is known regarding whether betel nut chewing can serve as a prognostic factor for smoking patients with locally advanced HNSCC receiving induction chemotherapy. The aim of this study was to evaluate the prognostic impact of betel nut chewing in such patients receiving induction chemotherapy with docetaxel, cisplatin, and fluorouracil (TPF). METHODS: From January 2010 to December 2012, we retrospectively analyzed 162 smoking patients with locally advanced HNSCC who received induction chemotherapy with TPF at our institution. Background characteristics, including a history of betel nut chewing, were analyzed as potential prognostic factors. RESULTS: Among the 162 smoking patients, 131 patients (81%) were betel nut chewers, while 31 (19%) were non-betel nut chewers. One hundred fifty-six (96%) were men, and 6 (4%) were women. The median age was 53 years. The overall response rates to induction chemotherapy were 57 and 77% in patients with and without betel nut chewing history, respectively (P = 0.038). The 2-year progression survival rates were 37 and 67% in patients with and without betel nut chewing history, respectively (P = 0.004). The 2-year overall survival rates were 47 and 71% in patients with and without betel nut chewing history, respectively (P = 0.017). Betel nut chewing history was independently associated with a poor response to induction chemotherapy, an inferior progression-free survival rate, and a poor overall survival rate. CONCLUSIONS: Our results indicate that betel nut chewing history is independently associated with poor prognosis in smoking patients with locally advanced HNSCC receiving induction chemotherapy with TPF. Further investigation is warranted to explain this effect of betel nut chewing history on these patients' prognosis.

RESUMO

BACKGROUND: Cancer stem cells (CSCs) are considered responsible for the recurrence and chemoresistance of cancer. Dysregulated autophagy is highly prevalent in many types of cancer including pancreatic cancer and has been implicated in cytoprotection and tumor promotion. This study aimed to investigate the role of autophagy in regulating cancer stemness and chemoresistance of pancreatic cancer. METHODS: The correlation between autophagy and CSCs and its clinical significance were analyzed using pancreatic cancer tissue microarrays. Genetic and pharmacological approaches were applied to explore the function of autophagy on CSC activity and gemcitabine resistance of pancreatic cancer cells in vitro and in vivo. RESULTS: LC3 expression positively correlated with the expression of CSC markers aldehyde dehydrogenase 1 (ALDH1), CD44, and CD133 in pancreatic cancer tissues. High coexpression of LC3/ALDH1 was associated with both poor overall survival and progression-free survival. In pancreatic cancer cell lines, higher LC3-II expression was observed in the sphere-forming cells than in the bulk cells. Blockade of autophagy by silencing ATG5, ATG7, and BECN1 or the administration of autophagy inhibitor chloroquine markedly reduced the CSC populations, ALDH1 activity, sphere formation, and resistance to gemcitabine in vitro and in vivo. Furthermore, osteopontin (OPN) was found to stimulate LC3-II, ALDH1, CD44, and CD133 expression in PANC-1 cells, whereas this effect could be prevented by OPN knockdown and autophagy blockade. After treatment with various inhibitors against the major signaling pathways downstream of OPN, only the inhibitor of NF-κB activation, BAY 1170-82, could effectively counteract OPN-induced autophagy and CSC activity. According to the histochemical results, pancreatic cancer patients manifesting high levels of OPN/LC3/ALDH1 and OPN/CD44/CD133 had poor survival. CONCLUSIONS: Induction of autophagy mediated by OPN/NF-κB signaling is required for maintenance of pancreatic CSC activity. Combination of gemcitabine with pharmacological autophagy inhibitors is a promising therapeutic strategy for pancreatic cancer.

RESUMO

UNLABELLED: Advanced hepatocellular carcinoma (HCC) remains a fatal disease even in the era of targeted therapies. Intra-arterial chemotherapy (IACT) can provide therapeutic benefits for patients with locally advanced HCC who are not eligible for local therapies or are refractory to targeted therapies. The aim of this retrospective study was to analyze the effect of IACT with cisplatin and doxorubicin on advanced HCC. METHODS: Patients with advanced HCC who were not eligible for local therapies or were refractory to sorafenib received doxorubicin (50 mg/m(2)) and cisplatin (50 mg/m(2)) infusions into the liver via the transhepatic artery. Between January 2005 and December 2011, a total of 50 patients with advanced HCC received this treatment regimen. The overall response rate (ORR) was 22% in all treated patients. In patients who received at least 2 cycles of IACT, the ORR was 36.7%, and the disease control rate was 70%. Survival rate differed significantly between patients who received only one cycle of IACT (group I) and those who received several cycles (group II). The median progression-free survival was 1.3 months and 5.8 months in groups I and II, respectively (P < 0.0001). The median overall survival was 8.3 months for all patients and was 3.1 months and 12.0 months in groups I and II, respectively (P < 0.0001). The most common toxicity was alopecia. Four patients developed grade 3 or 4 leukopenia. Worsening of liver function, nausea, and vomiting were uncommon side effects. This study demonstrated clinical efficacy and tolerable side effects of repeated IACT with doxorubicin and cisplatin in advanced HCC. Our regimen can be an alternative choice for patients with adequate liver function who do not want to receive continuous infusion of IACT.

RESUMO

OBJECTIVE: To investigate the clinical benefit of routine esophageal screening in newly diagnosed head and neck squamous cell carcinoma (HNSCC) patients. STUDY DESIGN: Retrospective cohort study. SETTING: Tertiary medical center. METHODS: This retrospective study selected newly diagnosed HNSCC patients from the Chang Gung Research Database between January 2007 and December 2019. Patients who underwent endoscopic esophageal examinations within 2 months of the initial diagnosis of HNSCC were included in the screening group. The clinical outcomes of the screening and nonscreening groups were analyzed. RESULTS: In total, 13,627 HNSCC patients were included, comprising 1032 females and 12,640 males (mean age 55.0 years), and the esophageal screening group included 7033 (51.4%) patients. The prevalence rate of esophageal tumors was 4.5%. Hypopharyngeal cancer patients were the most likely to have (13.4%) second primary esophageal tumors. The American Joint Committee on Cancer stage of the esophageal tumor was lower in the esophageal screening group than in the nonesophageal screening group. The oral, oropharyngeal, and hypopharyngeal cancer patients in the esophageal screening group had better survival outcomes than their counterparts in the nonesophageal screening group. CONCLUSION: Endoscopic esophageal screening of newly diagnosed HNSCC patients can detect esophageal tumors at an early stage and improve overall survival. Esophageal screening could be a routine survey in HNSCC patients, particularly those with lifestyle risk factors and in countries with a high prevalence of esophageal cancer.

RESUMO

BACKGROUND: a low PNI in patients with NPC is linked to poor survival, but prior studies have focused on single-timepoint measurements. Our study aims to employ joint modeling to analyze longitudinal PNI data from each routine visit, exploring its relationship with overall survival. METHODS: In this retrospective study using data from the Chang Gung Research Database (2007-2019), we enrolled patients with NPC undergoing curative treatment. We analyzed the correlation between patient characteristics, including the PNI, and overall survival. A joint model combining a longitudinal sub-model with a time-to-event sub-model was used to further evaluate the prognostic value of longitudinal PNI. RESULTS: A total of 2332 patient were enrolled for the analysis. Separate survival analyses showed that longitudinal PNI was an independent indicator of a reduced mortality risk (adjusted HR 0.813; 95% CI, 0.805 to 0.821). Joint modeling confirmed longitudinal PNI as a consistent predictor of survival (HR 0.864; 95% CI, 0.850 to 0.879). An ROC analysis revealed that a PNI below 38.1 significantly increased the risk of 90-day mortality, with 90.0% sensitivity and 89.6% specificity. CONCLUSIONS: Longitudinal PNI data independently predicted the overall survival in patients with NPC, significantly forecasting 90-day survival outcomes. We recommend routine PNI assessments during each clinic visit for these patients.

RESUMO

OBJECTIVE: Nutritional and inflammatory statuses have been associated with complications in microvascular-free flaps during head and neck surgeries. This study aimed to evaluate the potential of nutritional indicators in predicting postoperative free flap complications. STUDY DESIGN: We conducted a 20-year retrospective, case-control study within a defined cohort. SETTING: The study involved head and neck cancer patients from the Chang Gung Research Database who underwent simultaneous tumor ablation and free flap wound reconstruction between January 1, 2001, and December 31, 2019. METHODS: We employed logistic regression and stratified analysis to assess the risk of free flap complications and the subsequent need for flap revision or redo in relation to nutritional indicators and other clinical variables. RESULTS: Of the 8066 patients analyzed, 687 (8.5%) experienced free flap complications. Among these, 197 (2.4%) had free flap failures necessitating a redo of either a free flap or a pedicled flap. Beyond comorbidities such as chronic obstructive pulmonary disease, end-stage renal disease, and a history of prior radiotherapy, every 10-unit decrease in the preoperative prognostic nutritional index (PNI) was consistently associated with an increased risk of both free flap complications and failure. The covariate-adjusted odds ratios were 1.90 (95% confidence interval [CI]: 1.42-2.54) and 1.89 (95% CI: 1.13-3.17), respectively. CONCLUSION: A lower preoperative PNI suggests a higher likelihood of microvascular free flap complications in head and neck surgeries. Further randomized controlled trial designs are required to establish causality.

RESUMO

OBJECTIVE: The prognostic function of neurite growth-promoting factor 2 (Midkine (MK)) in adjuvant treatment of head and neck squamous cell carcinoma (HNSCC) is unclear. This study examined whether MK expression may predict treatment response and survival in resectable HNSCC patients. METHODS: In this retrospective study, MK expression in 144 HNSCC patients was analyzed by immunohistochemistry. A subset of patients (n = 10) had MK expression levels analyzed by western blot and semi-quantitative reverse transcription polymerase chain reaction. Data were analyzed using the Log-rank test and α = 0.05. RESULTS: Expression of MK was associated with poorer five-year progression-free and overall survival rates in HNSCC patients (p = 0.002). CONCLUSION: MK might play an important role in the progression of HNSCC and may be a useful prognostic factor.

RESUMO

BACKGROUND: The mainstay treatment of biliary tract cancer is complete tumor resection. Prior to surgery, risk stratification may help to predict and plan treatment approaches. In this study, we investigated the possibility of combining serum albumin concentrations and neutrophil-to-lymphocyte ratios (NLR) to create a score as ANS to predict the prognoses of biliary tract cancer before surgery. METHODS: This study retrospectively collected serum albumin concentration, neutrophil, and lymphocyte data measured in biliary tract cancer patients slated to receive complete tumor resections within two weeks before surgery. From January 2013 to December 2019, 268 biliary tract cancer patients who had received tumor resections at our hospital were categorized into 3 ANS groups: ANS = 0 (high albumin and low NLR), ANS = 1 (low albumin or high NLR), and ANS = 2 (low albumin and high NLR). RESULTS: Five-year survival rates were 70.1%, 47.6%, and 30.8% in the ANS = 0, 1, and 2 groups, respectively. The median overall survival time for the ANS = 0 group could not be determined by the end of the study, while those for ANS = 1 and ANS = 2 groups were 54.90 months and 16.62 months, respectively. The results of our multivariate analysis revealed that ANS could be used as an independent predictor of overall and recurrent-free survival. A high ANS was also correlated with other poor prognostic factors. CONCLUSIONS: The ANS devised for this study can be used to predict postoperative survival in patients with BTC and to guide treatment strategies.

RESUMO

This study evaluated the clinical characteristics of head and neck cancer (HNC) patients with hepatitis B (HBV) or hepatitis C (HCV) who underwent concurrent chemoradiotherapy (CCRT) and examined the prognostic impact of antiviral therapies. In a 19-year retrospective analysis of 8224 HNC patients treated with CCRT, 29.8% (2452) were diagnosed with HBV or HCV, of whom 714 received antiviral therapy. For non-metastatic HNC patients on CCRT, factors such as gender, Charlson Comorbidity Index (CCI), liver cirrhosis markers (Fibrosis-4, APRI), and initial tumor stage were significant determinants of their overall survival. However, the presence of HBV or HCV and the administration of antiviral treatments did not yield distinct survival outcomes. In summary, antiviral therapy for HBV or HCV did not affect the 5-year survival rates of non-metastatic HNC patients undergoing CCRT, while gender, tumor stage, CCI, and liver cirrhosis were notable prognostic indicators.

RESUMO

BACKGROUND: Incidence of fungal rhinosinusitis has increased in recent few years. We investigated the differences in microbiological findings between patients with fungal and non-fungal rhinosinusitis by growing microbiological cultures from samples obtained from sinus surgery. METHODS: Using the Chang Gung Research Database, we enrolled all chronic rhinosinusitis (CRS) patients who had ever undergone sinus surgery from 2001 to 2019 and had microbiological culture during sinus surgery. Enrolled patients were divided into fungal and non-fungal groups, based on fungal culture and surgical pathology. RESULTS: A total of 898 patients were diagnosed with fungal rhinosinusitis and 2884 with non-fungal rhinosinusitis. The fungal group had a higher age distribution (56.9 ± 13.1 vs. 47.0 ± 14.9), a larger proportion of females (62.4% vs. 37.0%), more unilateral lesions (80.4% vs. 41.6%), a lower incidence of the need for revision surgery (3.6% vs. 6.0%, p = 0.004), and a higher proportion of Pseudomonas aeruginosa in the culture (14.3% vs. 4.6%, p < 0.001). CONCLUSIONS: This large-scale study showed that Pseudomonas aeruginosa are more commonly found in patients with fungal rhinosinusitis and in patients who needed revision surgery, suggesting that efforts aimed at eliminating Pseudomonas are needed in order to improve the disease outcomes of patients with fungal rhinosinusitis.

RESUMO

AIM: Buprenorphine is one of the strongest opioids used for the relief of cancer pain. This study aims to evaluate the real-world clinical experiences of transdermal buprenorphine used in moderate to severe cancer pain in the Asian population. METHODS: This is an open-labeled, multicenter, 4-week observational study. Stable cancer pain patients who decided to switch the previous opioid to transdermal buprenorphine will be enrolled in this study. The safety and effectiveness were observed and collected. Pain assessment was performed using a numerical rating scale by the investigators and the Brief Pain Inventory Short Form (BPI-SF) by the patient. The safety profiles included concomitant medications and adverse events (AEs). RESULTS: A total of 83 patients were enrolled in this study. The global pain scores in the BPI, as well as the four individual pain parameters (worst, least, average, and right now), showed a continued decrease (p < .05) from week 2 to week 4. Significant improvements were observed in normal work activities, relations with other people, sleep, enjoyment of life, and global BPI pain interference score on week 4. Pain assessments conducted by investigators demonstrated significant, continuous improvements during the study periods. In addition, transdermal buprenorphine demonstrated good safety/tolerability with limited drug-related AEs in the Asian population with cancer pain. CONCLUSION: This study demonstrated that transdermal buprenorphine in the Asian population has good safety profiles and continued improvements in pain relief, sleep, and pain interferences. Transdermal buprenorphine can be an effective and convenient option as a transdermal opioid for patients with moderate to severe cancer pain in Taiwan. (NCT Number: NCT04315831).

RESUMO

Pancreatic cancer is a highly aggressive malignancy with a poor prognosis. Over the past decade, significant therapeutic advancements have improved the survival rates of patients with pancreatic cancer. One of the primary factors contributing to these positive outcomes is the evolution of chemotherapy, from monotherapy to doublet or triplet regimens, and the integration of multimodal approaches. Additionally, targeted agents tailored to patients with specific genetic alterations and the development of cell therapies show promise in benefiting certain subpopulations. This article focuses on examining pivotal studies that explore the role of chemotherapy in neoadjuvant, adjuvant, maintenance, and salvage settings; highlights interesting findings related to cell therapy; and provides an overview of ongoing trials concerning metastatic settings. This review primarily aimed to offer recommendations based on therapeutic evidence, recent advancements in new treatment combinations, and the most innovative approaches. A unique aspect of this review is the inclusion of published papers on clinical trials and real-world data in Taiwan, thus adding a valuable perspective to the overall analysis.
