RESUMEN
PURPOSE: Health-related quality of life (HRQoL) is associated with treatment-related complications and poor survival in patients with head and neck cancer (HNC). We investigated the effects of frailty on HRQoL in patients with HNC receiving definitive concurrent chemoradiotherapy (CCRT). METHODS: A total of 461 consecutive patients with locally advanced HNC who received CCRT between 2017 and 2018 at three medical centers in Taiwan were included. Frailty and HRQoL were assessed using the Comprehensive Geriatric Assessment and QLQ-H&N35 before CCRT. The sum score was calculated based on the first 30 questions of QLQ-H&N35. Multivariate analysis was performed to evaluate the impact of frailty on HRQoL. RESULTS: The overall sum score was 39 (34-49). The sum scores of patients with impairments in 0, 1, 2, 3, and ≥ 4 frailty domains were 34 (32-38), 40 (34-47), 46 (36-55), 48 (41-64), and 56 (50-60), respectively. Patients with impairments in more frailty domains had a higher symptom burden (p for trend < 0.001). Frail patients tended to experience symptoms across all QLQ-H&N35 subscales. Sex, body mass index, tumor type, tumor stage, Eastern Cooperative Oncology Group performance status, and frailty were determinants of HRQoL in the univariate analysis. Frailty was an independent determinant of HRQoL in the multivariate analysis. CONCLUSION: Routine frailty assessment may serve as a surrogate for the selection of patients with HNC with poor HRQoL before CCRT. Further studies are needed to determine whether appropriate interventions in frail patients would improve their HRQoL during CCRT.

BACKGROUND: Health-related quality of life (HRQoL) is a predictor of treatment outcomes in cancer patients. This study aimed to evaluate the effect of pretreatment HRQoL on treatment tolerance and survival outcomes in patients with HNC planned for concurrent chemoradiotherapy (CCRT) in Taiwan. METHODS: This study included 461 patients with HNC planned for definitive CCRT at three medical centers in Taiwan between August 2017 and December 2018. HRQoL was assessed using the QLQ-HN35 one week before the initiation of CCRT. Patients were grouped based on the sum scores of QLQ-HN35 (
RESUMEN
PURPOSE: There is no consensus on the selection of appropriate prophylactic tube feeding in patients with head and neck squamous cell carcinoma (HNSCC) undergoing concurrent chemoradiotherapy (CCRT). This study aimed to evaluate the effect of prophylactic tube feeding in patients with HNSCC who presented with a high Mallampati score and underwent CCRT. METHODS: We prospectively enrolled 185 consecutive patients with stage II to IVa HNSCC and a pre-treatment Mallampati score of 3 or 4 who received CCRT between August 2017 and December 2018 with follow-up data collected retrospectively. Patients were divided to either with or without prophylactic tube feeding group for comparison of treatment tolerance, toxicities, and quality of life(QOL). Propensity score matching (PSM) was used to achieve balanced covariates across the two groups. RESULTS: Of the cohort, 52 (28.1%) and 133 (71.9%) patients were allocated to the prophylactic and non-prophylactic tube feeding groups, respectively. Before and after PSM, patients in the tube feeding group had a significantly lower incidence of incomplete radiotherapy, incompletion of chemotherapy, emergency room visits, and grade 3 or higher infection, and improved symptoms of quality of life after CCRT than those in the non-tube feeding group. CONCLUSION: Prophylactic tube feeding was associated with better treatment tolerance, safety profiles, and quality of life in patients with HNSCC and high Mallampati scores who underwent CCRT. Therefore, Mallampati score might serve as a clinical tool for proactive selection of patients receiving prophylactic tube feeding in HNSCC patients upon receiving CCRT.

BACKGROUND: Whether the prevalence of frailty and its clinical significance are relevant to treatment outcomes in younger (aged < 65 years) cancer patients remains uncertain. This study aimed to evaluate the impact of frailty on treatment outcomes in younger cancer patients with head and neck and esophageal malignancy. MATERIAL AND METHODS: This multicenter prospective study recruited 502 patients with locally advanced head and neck and esophageal cancer during 2016-2017 in Taiwan, aged 20-64 years who received curative-intent concurrent chemoradiotherapy (CCRT) as first-line antitumor treatment. Baseline frailty assessment using geriatric assessment (GA) was performed for each patient within 7 days before CCRT initiation. RESULTS: Frailty was observed in 169 (33.7%) of 502 middle-aged patients. Frail patients had significantly higher incidences of chemotherapy incompletion (16.6% versus 3.3%, P < .001) and radiotherapy incompletion (16.6% versus 3.6%, P < .001) than fit patients. During CCRT, frail patients had a significantly higher percentage of hospitalizations (42.0% versus 24.6%, P < .001) and a trend toward a higher percentage of emergency room visits (37.9% versus 30.0%, P = .08) than fit patients. Frail patients more likely had a significantly higher incidence of grade ≥ 3 adverse events than fit patients during CCRT. The 1-year survival rate was 68.7% and 85.2% (hazard ratio 2.56, 95% confidence interval 1.80-3.63, P < .001) for frail and fit patients, respectively. CONCLUSIONS: This study demonstrated the significance of pretreatment frailty on treatment tolerance, treatment-related toxicity, and survival outcome in younger patients with head and neck and esophageal cancer undergoing CCRT. While GA is commonly targeted toward the older population, frailty assessment by GA may also be utilized in younger patients for decision-making guidance and prognosis prediction.

BACKGROUND: Nutritional counseling is frequently overlooked in cancer patients with normal nutritional status. This study aimed to evaluate the impact of nutritional counseling in head and neck cancer (HNC) patients with normal nutritional status prior to concurrent chemoradiotherapy (CCRT). METHODS: A total of 243 patients with pretreatment normal nutritional status and locally advanced HNC receiving concurrent chemoradiotherapy (CCRT) at three medical centers were enrolled. All patients were retrospectively allocated into the early (≤ 2 weeks, n = 105, 43.2%), late (> 2 weeks, n = 102, 42.0%), and no nutritional counseling groups (n = 36, 14.8%) according to the time interval between the date of CCRT initiation and the first date of nutritional counseling for comparison. RESULTS: The 1-year overall survival rates were 95.0%, 87.5%, and 81.3% in the early, late, and no nutritional counseling groups (p = 0.035), respectively. The median body weight changes at end of CCRT were - 4.8% (range, - 13.3 to 8.7%), - 5.6% (range, - 21.9 to 5.6%), and - 8.6% (range, - 20.3 to 2.4%) in patients in the early, late, and no nutritional counseling groups, respectively. The early termination of chemotherapy rates and the incompletion rates of planned radiotherapy were 1.9% and 1.9%, 2.9%, and 2.0%, 13.9%, and 19.4% in patients in the early, late, and no nutritional counseling groups, respectively. CONCLUSIONS: Our findings strongly suggest that while some HNC patients may have pretreatment normal nutritional status, early nutritional counseling is nevertheless essential for the improvement of treatment tolerance and survival outcome.

BACKGROUND: Concurrent chemoradiotherapy (CCRT) treatment incompletion is a known negative prognosticator for patients with head and neck cancer (HNC). Malnutrition is a common phenomenon which leads to treatment interruption in patients with HNC. We aimed to compare the performance of three nutritional tools in predicting treatment incompletion in patients with HNC undergoing definitive CCRT. MATERIAL AND METHODS: Three nutritional assessment tools, Mini Nutritional Assessment-Short Form (MNA-SF), Malnutritional Universal Screening Tool (MUST), and Nutritional Risk Screening 2002 (NRS-2002), were prospectively assessed prior to CCRT for HNC patients. Patients were stratified into either normal nutrition or malnourished groups using different nutrition tools. Treatment incompletion and treatment-related toxicities associated with CCRT were recorded. RESULTS: A total of 461 patients were included in the study; malnourished rates ranged from 31.0 to 51.0%. The CCRT incompletion rates were 4.9-6.3% and 14.5-18.2% for normal nutrition patients and malnourished patients, respectively. The tools had significant correlations with each other (Pearson correlation 0.801-0.837, p<0.001 for all) and accurately predicted the incompletion of CCRT. MNA-SF had the highest performance in predicting treatment-related toxicity, including emergency room visits, need for hospitalization, any grade III or higher hematological adverse events, and critical body weight loss, compared to the other tools. CONCLUSIONS: MNA-SF, MUST, and NRS2002 were all shown to be competent tools for prediction of treatment incompletion and treatment-related toxicity in HNC patients undergoing CCRT. We suggest implementing nutritional assessment prior to treatment to improve the rate of treatment completion and to reduce treatment-related toxicity in HNC patients.

BACKGROUND: No gold standard of nutritional assessment is established among patients with head and neck cancer (HNC) receiving concurrent chemoradiotherapy (CCRT). This study aimed to evaluate the clinical significance of pre-treatment nutritional status using the Mini Nutritional Assessment-short form (MNA-SF) among HNC patients receiving CCRT. METHODS: A total of 461 consecutive patients with newly diagnosed HNC treated with definitive CCRT at three medical institutes were prospectively enrolled. Nutritional status was assessed using MNA-SF within 7 days before CCRT initiation. Patients were classified as having normal nutrition, at risk of malnutrition, and malnourished groups according to MNA-SF for comparison. RESULTS: The 1-year overall survival rates were 89.8%, 76.8%, and 67.7% in the normal nutrition, at risk of malnutrition, and malnourished groups, respectively. Patients with normal nutrition had significantly lower rates of uncompleted radiotherapy and chemotherapy (4.5% and 4.1%, respectively) compared with patients at risk for malnutrition (14.1% and 11.5%, respectively) and those malnourished (11.1% and 11.1%, respectively). Patients with normal nutrition had significantly lower treatment-related complication rates regarding emergency room visits, hospital admission, and need for tubal feeding than those with at risk of malnutrition and malnourished. Patients with normal nutrition had significantly fewer severe hematologic toxicities (p = 0.044) and severe non-hematologic toxicities (p = 0.012) of CCRT than those malnourished. CONCLUSION: Pre-CCRT nutritional status identifies HNC patients vulnerable to treatment interruption and treatment complications. We suggest that nutritional assessment with MNA-SF should be incorporated in pre-CCRT evaluation for all HNC patients.

Hepatitis C virus-associated immune thrombocytopenia (HCV-ITP) has been assumed to be one of secondary ITP and associated with antiplatelet antibodies. This study was to clarify the antibody profile in HCV-ITP compared with primary ITP. We enrolled 55 HCV-ITP, 30 primary ITP, 11 Helicobacter pylori-ITP, 21 HCV control, and 16 healthy volunteers. We reviewed their blood cell counts, autoimmune markers, and spleen size. We used enzyme-linked immunosorbent assay kit to detect the specific antibody to glycoproteins IIb/IIIa, Ia/IIa, Ib/IX, IV, and human leukocyte antigen (HLA) class I. Compared with primary ITP patients, HCV-ITP patients had an older age, lower white blood cell (WBC) count and fewer presented with severe thrombocytopenia. The rate of positive antibody detection was 63.6% for the HCV-ITP group higher than the rate of 40% for the primary ITP. In the HCV control, antiplatelet antibodies were detected in 38.1% patients and no one had more than two types of antibodies. The antiplatelet antibodies correlated to severer thrombocytopenia. An HLA class I antibody was associated with lower WBCs and larger spleen. In conclusion, HCV-ITP patients had a high rate of positive antiplatelet antibody. The antibodies were associated with not only lower platelets but also leukopenia and splenomegaly.

BACKGROUND/PURPOSE: Ropeginterferon alpha-2b (Ropeg) is a novel pegylated interferon-alpha recently approved for the treatment of polycythemia vera (PV) in Europe. However, other than data from clinical trials, little is known about this agent in real world practice. METHODS: A compassionate use program employing Ropeg for treating patients with unmet medical need was initiated in Taiwan in 2017. Herein, we collected clinical data and assessed the safety as well as efficacy of Ropeg in nine patients treated in this program. RESULTS: Collectively, among evaluable patients, both the molecular response and complete blood count remission rates were 62.5%. Most therapy-related side effects were mild, and there was no treatment discontinuation attributable to intolerable adverse events. The agent also showed efficacy in symptom amelioration and spleen size reduction. Although no specific patterns of cytokine level alteration could be identified, significantly attenuated plasma levels of inflammation markers were observed in one particular patient who happened to have normalized spleen size and most remarkable reduction in JAK2 mutant allele burden, indicating all-around improvement in every aspect of this case. Furthermore, plasma hepcidin levels increased in two-thirds of PV patients, illustrating the potential of Ropeg to restore normal regulation of erythropoiesis. Using RNA sequencing on pre- and post-treatment samples from one patient, we demonstrated altered expression of genes participating in IFN response, inflammation, apoptosis, and cellular differentiation. CONCLUSION: Conclusively, observed signs of efficacy and safety in our real-world experience prove Ropeg as a promising option for the treatment of MPN.

Significant phenotypic heterogeneity exists in patients with all subtypes of myeloproliferative neoplasms (MPN), including essential thrombocythaemia (ET). Single-cell RNA sequencing (scRNA-Seq) holds the promise of unravelling the biology of MPN at an unprecedented level of resolution. Herein we employed this approach to dissect the transcriptomes in the CD34+ cells from the peripheral blood of seven previously untreated ET patients and one healthy adult. The mutational profiles in these patients were as follows: JAK2 V617F in two, CALR in three (one type I and two type II) and triple-negative (TN) in two. Our results reveal substantial heterogeneity within this enrolled cohort of patients. Activation of JAK/STAT signalling was recognized in discrepant progenitor lineages among different samples. Significantly disparate molecular profiling was identified in the comparison between ET patients and the control, between patients with different driver mutations (JAK2 V617F and CALR exon 9 indel), and even between patients harbouring the same driver. Intra-individual clonal diversity was also found in the CD34+ progenitor population of a patient, possibly indicating the presence of multiple clones in this case. Estimation of subpopulation size based on cellular immunophenotyping suggested differentiation bias in all analysed samples. Furthermore, combining the transcriptomic information with data from targeted sequencing enabled us to unravel key somatic mutations that are molecularly relevant. To conclude, we demonstrated that scRNA-Seq extended our knowledge of clonal diversity and inter-individual heterogeneity in patients with ET. The obtained information could potentially leapfrog our efforts in the elucidation of the pathogenesis of the disease.

BACKGROUND: Determining survival outcome in advanced pancreatic ductal adenocarcinoma (aPDAC) patients receiving second-line (L2) chemotherapy is important for clinical decision-making. The Besançon group from France recently proposed a prognostic nomogram to predict overall survival (OS) for aPDAC patients receiving L2 chemotherapy. The present study aimed to externally validate the performance of the Besançon nomogram in predicting OS in an Asian cohort. METHODS: We retrospectively enrolled 349 patients who received L2 chemotherapy for aPDAC between 2010 and 2016â¯at four institutes in Taiwan. The performance of the Besançon model in this cohort was evaluated with C-index and calibration plots. RESULTS: The median OS time in our patient cohort was 4.5 months (95% confidence interval [CI], 3.0-5.0). Using the Besançon nomogram-predicted risk groups, the median OS times in the low, intermediate, and high-risk groups were 6.7 (95% CI, 5.3-8.2), 3.2 (95% CI, 2.4-3.9), and 1.7 months (95% CI, 0.6-2.7), respectively. The C-index of the predicted six- and 12-month survival probabilities for the Besançon nomogram were 0.766 (95% CI, 0.715-0.816) and 0.698 (95% CI, 0.641-0.754), respectively. The calibration plot showed that the observed six-month survival probability was close to the diagonal line, while that for 12-month survival deviated below the diagonal line compared to the survival probability predicted by the Besançon nomogram. CONCLUSIONS: Although the Besançon nomogram tended to over-estimate the 12-month survival probability, our study demonstrated that the nomogram is a reliable and readily applicable model to estimate survival outcomes of aPDAC patients receiving L2 chemotherapy.

BACKGROUND AND AIM: Given that a wide variation in tumor response rates and survival times suggests heterogeneity among the patients with advanced pancreatic cancer (APC) who underwent second-line (L2) chemotherapy, it is a challenge in clinical practice to identify patients who will receive the most benefit from L2 treatment. METHODS: We selected 183 APC patients who received L2 palliative chemotherapy between 2010 and 2016 from a medical center as the development cohort. A Cox proportional hazard model was used to identify the prognostic factors and construct the nomogram. An independent cohort of 166 patients from three other hospitals was selected for external validation. RESULTS: The nomogram was based on eight independent prognostic factors from the multivariate Cox model: sex, Eastern Cooperative Oncology Group performance status, reason for first-line treatment discontinuation, duration of first-line treatment, neutrophil-to-lymphocyte ratio, tumor stage, body mass index, and serum carbohydrate antigen 19-9 levels at the beginning of L2 treatment. The model exhibited good discrimination ability, with a C-index of 0.733 (95% confidence interval, 0.681-0.785) and 0.724 (95% confidence interval, 0.661-0.787) in the development and validation cohorts, respectively. The calibration plots of the development and validation cohorts showed optimal agreement between model prediction and actual observation in predicting survival probability at 6 months, 1 year, and 2 years. CONCLUSIONS: This study developed and externally validated a prognostic model that accurately predicts the survival outcome of APC patients before L2 palliative chemotherapy, which could assist in clinical decision-making, counseling for treatment, and most importantly, prognostic stratification of patients.

BACKGROUND: Cancer-related fatigue (CRF) is an emerging clinical issue, although its prevalence and impact on quality of life (QOL) in cancer patients in Taiwan remain unclear. The present nationwide cross-sectional study was conducted to provide a thorough overview of the prevalence, related factors and impact of CRF in Taiwan. METHODS: In this multi-center survey, data were collected using the International Classification of Diseases 10th Revision (ICD-10) Fatigue evaluation, Brief Fatigue Inventory-Taiwan (BFI-T), the Chinese version of the Symptom Distressed Scale and a fatigue experience survey. Logistic regression was used to determine the correlations between fatigue characteristics and the factors studied. RESULTS: A total of 1207 cancer patients were recruited from 23 hospitals in Taiwan. Fatigue was the most distressing symptom in Taiwanese cancer patients. The distress score was higher if CRF was diagnosed using ICD-10 compared with BFI-T. Rest and nutritional supplementation were the most common non-pharmacological treatments; blood transfusion was the most common pharmacological treatment. There were 45% of patients reported not receiving a timely intervention for fatigue. CONCLUSIONS: Fatigue is the most bothersome symptom reported by Taiwanese cancer patients. Caregivers should be aware of the impact of CRF on QOL in cancer patients, constantly measure the severity of fatigue and provide appropriate interventions.

BACKGROUND: Acute renal impairment (ARI) is a major complication after cytoreductive surgery and hyperthermic intraperitoneal chemotherapy (CRS/HIPEC) for cancer patients with peritoneal metastases. This study aimed to investigate the incidence and identify the risk factors of post-HIPEC creatinine increased. METHODS: From April 2015 to December 2019, demographic and perioperative data of 169 patients undergoing CRS/HIPEC with a preoperative creatinine level <1.5 mg/dL were retrospectively reviewed. Renal impairment was defined according to the National Cancer Institute Common Terminology Criteria for Adverse Events (NCI-CTCAE) version 5.0. The risk factors of creatinine increased were analyzed using univariate and multiple logistic regression analyses. RESULTS: Among the 169 enrolled patients, 21 (12.4%) had postoperative creatinine increased (ARI group) and 148 (87.6%) did not (non-ARI group). Significantly more of the ARI group received a cisplatin HIPEC regimen than the non-ARI group (71.4 vs. 37.8%, p = 0.004). Multiple logistic regression analysis revealed that the patients who received a cisplatin HIPEC regimen (adjusted odds ratio [AOR] = 11.38, p < 0.001) and peritoneal dialysis solution as HIPEC perfusate (AOR = 7.07, p = 0.002) were more likely to develop post-HIPEC creatinine increased. CONCLUSIONS: Identifying the risk factors of post-HIPEC creatinine increased can help to improve patient selection, a dose of HIPEC regimens modification and perioperative care. We also identified the detrimental renal effect of peritoneal dialysis solution as HIPEC perfusate. More prospective studies are warranted to confirm these findings.

BACKGROUND: Research on cancer survivorship associated with nasopharyngeal carcinoma (NPC) is rare. We aimed to elucidate the risk of ischemic stroke in 5-year survivors of NPC following radiotherapy (RT) or concurrent chemoradiation therapy (CCRT). SUBJECTS, MATERIALS, AND METHODS: NPC survivors, defined as those who survived longer than 5 years after diagnosis, were identified and matched at a 1:5 ratio with normal controls from the Longitudinal Health Insurance Database 2005 of Taiwan. The stratified Cox regression models were used to access the risk of ischemic stroke, with adjustment for age, treatment modality, comorbidities, and socioeconomic characteristics. RESULTS: From 2000 to 2005, a total of 3,016 NPC survivors who had received RT (n = 959) or CCRT (n = 2,057) and 15,080 controls were matched for age, sex, income, and urbanization level. The risk of ischemic stroke was significantly higher in the NPC survivor cohort than in the control cohort. Stroke was positively related to death. Moreover, the age onset of stroke for NPC survivors was 10 years earlier than that for the general population. CONCLUSION: Not only was the stroke risk in NPC survivors higher than that in the general population, but the onset age was also 10 years earlier. Future survivorship care should include ischemic stroke as a late complication, for its proper prevention and management. IMPLICATIONS FOR PRACTICE: Nasopharyngeal carcinoma (NPC) is endemic in Taiwan, and its 5-year survival is 65.2%. With the increased 5-year cancer survivors, survivorship has become an important issue. However, research on NPC survivorship is very rare. To the authors' knowledge, this is the first population-based study on long-term NPC survivors. This study's results indicated that not only was the risk of ischemic stroke in NPC survivors at least triple that of the general population, but the onset age was also 10 years earlier. These results may provide solid evidence that survivorship care guidelines should include stroke as a late complication in 5-year NPC survivors, for its proper prevention and management.

PURPOSE: Poor adherence to analgesic drugs is one of the most common barriers to adequate pain management. This prospective, cross-sectional, patient-oriented observational study aimed to explore the adherence rate, clinical factors, and impact of adherence to analgesic drugs on the quality of life (QoL) among cancer outpatients in Taiwan. METHODS: Eight hundred ninety-seven consecutive adult outpatients with cancer who had reported tumor pain and received regular analgesic drug treatment were enrolled from 16 medical centers across Taiwan. The Brief Pain Inventory was used to assess pain intensity and QoL. Morisky's four-item medication adherence scale was used to assess adherence to analgesic drugs. Clinical factors possibly associated with good adherence to analgesic drugs were analyzed using multivariate logistic regression analyses. RESULTS: Of the 897 patients, 26.9% met criteria for the good, 35.5% for the moderate, and 37.6% for the poor adherence groups. The good adherence group had significantly better QoL outcomes than the moderate and poor adherence groups (all p < 0.05). Age ≥ 50 years, head and neck or hematological malignancies, cancer-related pain, patients who agreed or strongly agreed that the side effects of analgesic drugs were tolerable, and patients who disagreed or strongly disagreed that the dosing schedule could be flexibly self-adjusted to deal with the actual pain were predictors of good adherence to analgesic drugs. CONCLUSIONS: Awareness of the clinical factors associated with adherence to analgesic drugs may help clinicians to identify cancer patients at a greater risk of non-adherence, reinforce optimal pain management, and improve the QoL by enhancing adherence to pain medications.

The purpose of this study was to evaluate the longitudinal incidence, severity, pattern of changes or predictors of oxaliplatin-induced peripheral neuropathy (OXAIPN) in Taiwanese patients with colorectal cancer. A longitudinal repeated measures study design was employed, and 77 participants were recruited from the colorectal and oncology departments of two teaching medical centres in Taiwan. Physical examinations were performed, and self-reports regarding adverse impacts of OXAIPN and quality of life were obtained at five time points throughout 12 cycles of chemotherapy (C/T). The incidence of OXAIPN increased with C/T cycles (31.1%-81.9%), and the upper limb numbness and cold sensitivity were most significant acute OXAIPN symptoms (29.9%-73.6%). Findings also documented significant increases in overall severity, symptom distress, interference and physical results associated with OXAIPN over the course of C/T. Predictors of OXAIPN severity varied by treatment cycle, including younger patient, higher cumulative dose of oxaliplatin, greater body surface area, receipt of chemotherapy in winter and the occurrence of OXAIPN during prior C/T cycles. The results from this study might help healthcare providers to recognise the symptom characteristics, degree of influences, trends and high-risk group of OXAIPN, facilitating early evaluation and potential interventions to mitigate or prevent negative effects of OXAIPN on patients.

BACKGROUND: Cytoreductive surgery with hyperthermic intraperitoneal chemotherapy (CRS/HIPEC) is an emerging surgical procedure for peritoneal carcinomatosis (PC). CRS/HIPEC is a complicated treatment that requires multi-disciplinary teamwork (MDT), which may be lacking when establishing a CRS/HIPEC programme. Herein, we report our preliminary treatment outcomes with the early implementation of an MDT model for CRS/HIPEC. METHODS: From April 2015 to December 2016, 45 patients with a diagnosis of PC who received CRS/HIPEC were reviewed retrospectively in a single institution in Taiwan. RESULTS: Among the 45 patients, CRS was mainly performed by laparotomy (n = 42), and only three patients with limited PC underwent laparoscopic CRS. The first 13 patients received treatment before the MDT had been established (group 1), and the other 32 patients were treated after the MDT had been established (group 2). The highest peri-HIPEC body temperature in group 2 was significantly lower than that in group 1 (36.8 °C vs. 37.5 °C, p < 0.001). Overall, eight patients experienced major complications. The trend of a lower major complication rate was observed after the MDT model had been implemented (30.7% in group 1 vs. 12.4% in group 2, p = 0.202). Pre-CRS/HIPEC abdominal pain significantly increased the risk of post-operative major complications (p = 0.017). CONCLUSIONS: Our experience suggests that the early implementation of an MDT model when establishing a CRS/HIPEC programme at a single institution may result in a higher complete cytoreduction rate and lower major complication rate, and also shorten the learning curve of this complicated procedure.

High mobility group AT-hook 2 (HMGA2) is an architectural transcription factor that is negatively regulated by let-7 microRNA through binding to it's 3'-untranslated region. Transgenic mice expressing Hmga2 with a truncation of its 3'-untranslated region has been shown to exhibit a myeloproliferative phenotype. To decipher the let-7-HMGA2 axis in myeloproliferative neoplasms, we employed an in vitro model supplemented with clinical correlation. Ba/F3 cells with inducible JAK2V617F expression (Ton.JAK2.V617F cells) showed upregulation of HMGA2 with concurrent let-7a repression. Ton.JAK2.V617F cells treated with a let-7a inhibitor exhibited further escalation of Hmga2 expression, while a let-7a mimic diminished the Hmga2 transcript level. Hmga2 overexpression conferred JAK2-mutated cells with a survival advantage through inhibited apoptosis. A pan-JAK inhibitor, INC424, increased the expression of let-7a, downregulated the level of Hmga2, and led to increased apoptosis in Ton.JAK2.V617F cells in a dose-dependent manner. In samples from 151 patients with myeloproliferative neoplasms, there was a modest inverse correlation between the expression levels of let-7a and HMGA2 Overexpression of HMGA2 was detected in 29 (19.2%) of the cases, and it was more commonly seen in patients with essential thrombocythemia than in those with polycythemia vera (26.9% vs 12.7%, P=0.044). Patients with upregulated HMGA2 showed an increased propensity for developing major thrombotic events, and they were more likely to harbor one of the 3 driver myeloproliferative neoplasm mutations in JAK2, MPL and CALR Our findings suggest that, in a subset of myeloproliferative neoplasm patients, the let-7-HMGA2 axis plays a prominent role in the pathogenesis of the disease that leads to unique clinical phenotypes.

BACKGROUND: Approximately, 50% of all gastric cancer patients are aged >70 y. Although curative surgery is the treatment of choice, many geriatric patients die of surgical complications. Therefore, we aimed to evaluate the impact of radical surgery on the survival outcome of geriatric patients with resectable gastric cancers. METHODS: About 488 patients diagnosed with resectable gastric cancers, aged ≥70 y, between January 2007 and December 2012 at Chang Gung Memorial Hospital (CGMH) Linkou branch were included in this study. Using univariate and multivariate analyses, possible prognostic variables for survival outcome were assessed in 445 patients (91.2%) treated with radical surgery (operation [OP] group) and 43 (8.8%) receiving conservative treatment (non-OP group). The impact of radical surgery on survival outcomes was evaluated according to CGMH scores. RESULTS: On multivariate analysis, surgical resection with subtotal gastrectomy and CGMH score were the only independent prognostic factors for both overall and cancer-specific survival. The median survival time was 43 mo for the entire cohort. The OP group had significantly better survival outcome than the non-OP group (median survival, 50.3 versus 16.2 mo, P < 0.001). The median survival times for patients with CGMH scores ≤20 were 64.1 and 20.0 mo (P < 0.002) and those for patients with CGMH scores >20 were 13.8 and 10.4 mo (P = 0.18) in the OP and non-OP groups, respectively. CONCLUSIONS: Surgical resection and CGMH score are independent prognostic factors for overall and cancer-specific survival; the CGMH score might be a prognostic indicator of surgical outcome in geriatric patients with resectable gastric cancers.
