Quality of life across chemotherapy lines in patients with cancers of the pancreas and biliary tract

Advancing patient-centered cancer care: a systematic review of electronic patient-reported outcome measures

Background

Electronic Patient-Reported Outcome Measures (ePROMs) have emerged as valuable tools in cancer care, facilitating the comprehensive assessment of patients' physical, psychological, and social well-being. This study synthesizes literature on the utilization of ePROMs in oncology, highlighting the diverse array of measurement instruments and questionnaires employed in cancer patient assessments. By comprehensively analyzing existing research, this study provides insights into the landscape of ePROMs, informs future research directions, and aims to optimize patient-centred oncology care through the strategic integration of ePROMs into clinical practice.

Methods

A systematic review was conducted by searching peer-reviewed articles published in academic journals without time limitations up to 2024. The search was performed across multiple electronic databases, including PubMed, Scopus, and Web of Science, using predefined search terms related to cancer, measurement instruments, and patient assessment. The selected articles underwent a rigorous quality assessment using the Mixed Methods Appraisal Tool (MMAT).

Results

The review of 85 studies revealed a diverse range of measurement instruments and questionnaires utilized in cancer patient assessments. Prominent instruments such as the European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire Core 30 (EORTC QLQ-C30) and the Patient Reported Outcome-Common Terminology Criteria for Adverse Events (PRO-CTCAE) were frequently referenced across multiple studies. Additionally, other instruments identified included generic health-related quality of life measures and disease-specific assessments tailored to particular cancer types. The findings indicated the importance of utilizing a variety of measurement tools to comprehensively assess the multifaceted needs and experiences of cancer patients.

Conclusion

Our systematic review provides a comprehensive examination of the varied tools and ePROMs employed in cancer care, accentuating the perpetual requirement for development and validation. Prominent instruments like the EORTC QLQ-C30 and PRO-CTCAE are underscored, emphasizing the necessity for a thorough assessment to meet the multifaceted needs of patients. Looking ahead, scholarly endeavours should prioritize the enhancement of existing tools and the creation of novel measures to adeptly address the evolving demands of cancer patients across heterogeneous settings and populations.

Durvalumab plus gemcitabine and cisplatin in advanced biliary tract cancer (TOPAZ-1): patient-reported outcomes from a randomised, double-blind, placebo-controlled, phase 3 trial

BACKGROUND

In the ongoing, randomised, double-blind phase 3 TOPAZ-1 study, durvalumab, a PD-L1 inhibitor, plus gemcitabine and cisplatin was associated with significant improvements in overall survival compared with placebo, gemcitabine, and cisplatin in people with advanced biliary tract cancer at the pre-planned intermin analysis. In this paper, we present patient-reported outcomes from TOPAZ-1.

METHODS

In TOPAZ-1 (NCT03875235), participants aged 18 years or older with previously untreated, unresectable, locally advanced, or metastatic biliary tract cancer with an Eastern Cooperative Oncology Group performance status of 0 or 1 and one or more measurable lesions per Response Evaluation Criteria in Solid Tumors (RECIST; version 1.1) were randomly assigned (1:1) to the durvalumab group or the placebo group using a computer-generated randomisation scheme. Participants received 1500 mg durvalumab or matched placebo intravenously every 3 weeks (on day 1 of the cycle) for up to eight cycles in combination with 1000 mg/m2 gemcitabine and 25 mg/m2 cisplatin intravenously on days 1 and 8 every 3 weeks for up to eight cycles. Thereafter, participants received either durvalumab (1500 mg) or placebo monotherapy intravenously every 4 weeks until disease progression or other discontinuation criteria were met. Randomisation was stratified by disease status (initially unresectable vs recurrent) and primary tumour location (intrahepatic cholangiocarcinoma vs extrahepatic cholangiocarcinoma vs gallbladder cancer). Patient-reported outcomes were assessed as a secondary outcome in all participants who completed the European Organisation for Research and Treatment of Cancer's 30-item Quality of Life of Cancer Patients questionnaire (QLQ-C30) and the 21-item Cholangiocarcinoma and Gallbladder Cancer Quality of Life Module (QLQ-BIL21). We calculated time to deterioration-ie, time from randomisation to an absolute decrease of at least 10 points in a patient-reported outcome that was confirmed at a subsequent visit or the date of death (by any cause) in the absence of deterioration-and adjusted mean change from baseline in patient-reported outcomes.

FINDINGS

Between April 16, 2019, and Dec 11, 2020, 685 participants were enrolled and randomly assigned, 341 to the durvalumab group and 344 to the placebo group. Overall, 345 (50%) of participants were male and 340 (50%) were female. Data for the QLQ-C30 were available for 318 participants in the durvalumab group and 328 in the placebo group (median follow-up 9·9 months [IQR 6·7 to 14·1]). Data for the QLQ-BIL21 were available for 305 participants in the durvalumab group and 322 in the placebo group (median follow-up 10·2 months [IQR 6·7 to 14·3]). The proportions of participants in both groups who completed questionnaires were high and baseline scores were mostly similar across treatment groups. For global health status or quality of life, functioning, and symptoms, we noted no difference in time to deterioration or adjusted mean changes from baseline were observed between groups. Median time to deterioration of global health status or quality of life was 7·4 months (95% CI 5·6 to 8·9) in the durvalumab group and 6·7 months (5·6 to 7·9) in the placebo group (hazard ratio 0·87 [95% CI 0·69 to 1·12]). The adjusted mean change from baseline was 1·23 (95% CI -0·71 to 3·16) in the durvalumab group and 0·35 (-1·63 to 2·32) in the placebo group.

INTERPRETATION

The addition of durvalumab to gemcitabine and cisplatin did not have a detrimental effect on patient-reported outcomes. These results suggest that durvalumab, gemcitabine, and cisplatin is a tolerable treatment regimen in patients with advanced biliary tract cancer.

The advantages, disadvantages, threats, and opportunities of electronic patient-reported outcome systems in cancer: A systematic review

Objective

Electronic patient-reported outcome (ePRO) systems hold promise for revolutionizing communication between cancer patients and healthcare providers across various care settings. This systematic review explores the multifaceted landscape of ePROs in cancer care, encompassing their advantages, disadvantages, potential risks, and opportunities for improvement.

Methods

In our systematic review, we conducted a rigorous search in Scopus, Web of Science, and PubMed, employing comprehensive medical subject heading terms for ePRO and cancer, with no date limitations up to 2024. Studies were critically appraised and thematically analyzed based on inclusion and exclusion criteria, including considerations of advantages, disadvantages, opportunities, and threats.

Findings

Analyzing 85 articles revealed 69 themes categorized into four key areas. Advantages (n = 14) were dominated by themes like "improved quality of life and care." Disadvantages (n = 26) included "limited access and technical issues." Security concerns and lack of technical skills were prominent threats (n = 10). Opportunities (n = 19) highlighted advancements in symptom management and potential solutions for technical challenges.

Conclusion

This review emphasizes the crucial role of continuous exploration, integration, and innovation in ePRO systems for optimizing patient outcomes in cancer care. Beyond traditional clinical settings, ePROs hold promise for applications in survivorship, palliative care, and remote monitoring. By addressing existing limitations and capitalizing on opportunities, ePROs can empower patients, enhance communication, and ultimately improve care delivery across the entire cancer care spectrum.

Evaluating the relationship between patient activation and health-related quality of life (HRQOL) in patients with pancreatic cancer (PwPC)

PURPOSE

Advanced pancreatic cancer is synonymous with a high mortality rate, debilitating symptom profile, and minimal prolongation in overall survival. Therefore, health-related quality of life (HRQOL) is important in patients with pancreatic cancer (PwPC). In chronic conditions, patient activation is positively associated and higher HRQOL. However, no known study has evaluated patient activation, HRQOL, and their association in PwPC.

METHODS

A 43-item cross-sectional survey assessed patient activation and HRQOL of patients with locally advanced and metastatic pancreatic cancer undergoing chemotherapy. Variables were analyzed descriptively, and relationships were assessed using bivariate statistics (sig p < 0.05).

RESULTS

Fifty-six patients participating in the study had an average age of 69.5 ± 11.1 years, and the majority were females (51.8%), Caucasians (61.8%), married/partnered (64.3%), and had at least a college degree (59%). Almost half were at stage 4 (48.2%), and most were newly diagnosed (66.1%). Mean patient activation score was 63.5 ± 17.2 (scale range: 0-100), with most at higher activation levels of 3 or 4 (66.7%). Mean HRQOL score of 41.0 ± 12.7 (scale range: 0-72) was low. Patient activation levels, age, education level, and gender explained 21% of variation in overall HRQOL scores. Patients at activation level 4 had significantly higher overall HRQOL versus those at lower activation (level 1 or 2). Higher patient activation was significantly associated with having either private insurance only or multiple insurances and being partnered.

CONCLUSION

Patient activation significantly predicted HRQOL in PwPC despite the low sample size. Initiatives to increase patient activation should focus on patients of low socioeconomic status and those without partner support.

Effects of intensive physiotherapy on Quality of Life (QoL) after pancreatic cancer resection: a randomized controlled trial

BACKGROUND

Patients have significantly lower QoL scores after pancreatic resection due to cancer in the physical and psychological domains compared to healthy controls or other cancer patients. Intensified physiotherapy or physical training can increase QoL by reducing fatigue levels and improving physical functioning. However, data on the long-term effects of intensive or supervised physiotherapy is lacking. The aim of this exploratory study is the assessment of QoL in the intervention group, using various QoL questionnaires in their validated German translations and gather data on its feasibility in the context of chemotherapy with a follow-up of 12 months (and develop concepts to improve QoL after pancreatic cancer resection).

METHODS

Fifty-six patients (mean age: 66.4 ± 9.9 years) were randomized in this study to intervention (cohort A, n = 28) or control group (cohort B, n = 28). Intervention of intensified physiotherapy program consisted of endurance and muscle force exercises using cycle ergometer. In the control group physiotherapy was limited to the duration of the hospital stay and was scheduled for 20 min on 5 days per week. The clinical visits took place 2 days preoperatively, 1 week, 3 months, 6 months and 12 months postoperatively. Both groups attended the follow-up program. QoL was evaluated using the Short Physical Performance Battery (SPPB), Short Form-8 Health Survey (SF-8) and the European Organization for Research and Treatment of Cancer (EORTC) QLQ-C30 and pancreatic cancer-specific module QLQ-PAN26 questionnaires. The course of QoL was evaluated using a repeated measures ANOVA and a per protocol design.

RESULTS

Of the initial 56 randomized patients, 34 finished the 12 months follow-up period. There were no adverse events due to the intervention and 80% of patients in the intervention group where adherent. There was no significant influence on physical performance as measured by SPPB and SF-8 questionnaire. However, after 6 months patients in the intervention group regained their prior physical condition, whereas the control group did not. Intensive physiotherapy significantly influenced various factors of QoL measured with the C30 questionnaire positively, such as physical functioning (p = 0.018), role functioning (p = 0.036), and appetite loss (p = 0.037), even after 6 months. No negative effects in patients undergoing chemotherapy compared to those without chemotherapy was observed.

CONCLUSION

This first randomized controlled study with a 12-month follow-up shows that supervised physiotherapy or prescribed home-based exercise after pancreatic cancer resection is safe and feasible and should be proposed and started as soon as possible to improve certain aspects of QoL.

Gastrointestinal malignancies and supportive care trials: a snapshot of the last two decades

BACKGROUND

Patients with gastrointestinal (GI) cancers experience a high symptom burden due to the effects of both cancer and treatment. As such, trials assessing symptom burden and supportive interventions are crucial. Here, we characterise the landscape of phase III GI cancer clinical trials and explore study outcomes centred on the patient's quality of life (QoL).

METHODS

We searched ClinicalTrials.gov for phase III randomised controlled trials (RCTs) registered between 2000 and 2017 that are assessing a therapeutic intervention in adult patients with cancer and grouped trials by GI disease sites.

RESULTS

Overall, we identified 76 phase III trials specific to GI cancers that enrolled a total of 53 725 patients. When analysing the primary outcomes measured, the vast majority of studies (n=71, 86%) measured disease-related endpoints such as progression-free survival or overall survival. All trials had a secondary endpoint that measured adverse events, but only 30 trials (39%) included QoL measures as secondary endpoints. Of the 30 trials that included QoL secondary endpoints, only 16 (53%) reported these results. Only five trials (7%) assessed interventions aimed at supportive measures impacting disease-related or treatment-related toxicity. None of the supportive trials included QoL as a primary endpoint and only two of these trials (40%) included QoL as a secondary endpoint.

CONCLUSIONS

Most GI cancer trials failed to incorporate patient-centred outcomes or QoL measures when studying new interventions. These findings call for greater integration of patient-reported metrics, which may lead to better care and outcomes for patients with GI malignancies.

The Appropriate First-Line Chemotherapy Regimen for Incurable Pancreatic Cancer in Clinical Practice: A Consideration of Patients' Overall Survival and Quality of Life

Purpose: For incurable pancreatic cancer, the therapeutic goal is to prolong survival and maintain the quality of life (QOL). Unexpected outpatient consultation (OCT) and emergency hospitalization lead to QOL deterioration. The National Comprehensive Cancer Network (NCCN) guidelines recommend 5-fluorouracil/leucovorin, oxaliplatin, and irinotecan (FOLFIRINOX) and gemcitabine plus albumin-bound paclitaxel (nabPTX+GEM) as the preferred first-line regimens. Japanese clinical practice guidelines further recommend GEM and tegafur/gimeracil/oteracil potassium (S-1). Currently, no treatment strategy considers QOL at any stage during a patient's clinical course.

Methods: In this study, hospital-free survival (HFS), defined as the period without hospitalization and OCT, was introduced as a new indicator of the qualitative aspect of overall survival (OS). We compared OS, length of hospitalization (LOH), OCT, and HFS for the four first-line chemotherapy groups.

Results: No significant difference was observed in the median OS and HFS, nor was there a strong correlation between OS and LOH, based on the four first-line chemotherapy groups. In contrast, there were strong correlations between OS and OCT and between OS and HFS in all first-line chemotherapy groups. The ratio of OCT to OS was similar for mFOLFIRINOX and nabPTX+GEM. S-1 had the lowest OCT-to-OS ratio. The ratio of HFS to OS declined from highest to lowest in the order S-1, nabPTX+GEM, mFOLFIRINOX, and GEM.

Conclusion: Our findings suggested existence of correlation differences between OS and HFS between first-line mFOLFIRINOX and first-line nabPTX+GEM. In addition, a good HFS was obtained with S-1 alone in some cases. In the future, clinical trials for chemotherapy should examine QOL during the entire clinical course.

A Mechanistic Overview of Taste Bud Maintenance and Impairment in Cancer Therapies

Since the early 20th century, progress in cancer therapies has significantly improved disease prognosis. Nonetheless, cancer treatments are often associated with side effects that can negatively affect patient well-being and disrupt the course of treatment. Among the main side effects, taste impairment is associated with depression, malnutrition, and morbid weight loss. Although relatively common, taste disruption associated with cancer therapies remains poorly understood. Here, we review the current knowledge related to the molecular mechanisms underlying taste maintenance and disruption in the context of cancer therapies.

Effects of Counselling on Quality of Life among Cancer Patients in Malaysia: A Randomized Controlled Trial

Background

We aimed to assess whether "Managing Patients on Chemotherapy" book is effective to improve quality of life (QOL) of cancer patient via counselling by pharmacist.

Methods

A randomized control trial study was run among 2120 cancer patients in public hospitals in Peninsular Malaysia, from Apr 2016-Jan 2018. The treatment group received counselling regarding chemotherapy by using developed module. The data were collected at three time-points: baseline, 1^st, 2^nd and 3^rd follow-ups after counseling by Validated Malay version of the WHOQOL-BREF of questionnaire. Data analyses were done using χ² and two-way repeated measure ANOVA.

Results

The treatment group improved significantly as compared to control group in physical health, psychological health, social relationship, environment and overall QOL (P<0.00).

Conclusion

The "Managing Patients on Chemotherapy" book along with repetitive counselling by pharmacists is a useful intervention for improving QOL of cancer patients undergoing treatment.

Prevalence and severity of long-term physical, emotional, and cognitive fatigue across 15 different cancer entities

Background

Fatigue prevalence and severity have been assessed in a variety of studies, yet, not in a standardized way, and predominantly in breast cancer patients. Systematic, comparative investigations across a broad range of cancer entities are lacking.

Methods

The FiX study systematically enrolled 2244 cancer patients across 15 entities approximately 2 years after diagnosis. Fatigue was assessed with the multidimensional EORTC QLQ‐FA12 questionnaire. Physical, emotional, cognitive, and total fatigue were compared across entities and with normative values of the general population. Differences in patients' characteristics and cancer therapy between entities were taken into account using analyses of covariance models.

Results

Across all entities, mean physical fatigue levels were significantly higher than age‐ and sex‐matched means of the general population for all cancer entities (all Bonferroni‐Holm adjusted P < .01). For most entities also emotional and cognitive fatigue levels were significantly higher than normative values. Age‐ and sex‐standardized physical fatigue prevalence ranged from 31.8% among prostate to 51.7% among liver cancer patients. Differences between entities could not be fully explained by sex, age, BMI, or cancer therapy. Adjusted for these factors, mean physical fatigue was higher for stomach (P = .0004), lung (P = .034), kidney (P = .0011), pancreas (P = .081), and endometrium (P = .022) compared to breast cancer patients. Adjusted means of emotional fatigue were also lowest in breast cancer patients and significantly higher in stomach (P = .0047), bladder (P = .0036), and rectal (P = .0020) cancer patients.

Conclusions

Physical, emotional, and cognitive fatigue is prevalent in all 15 investigated cancer entities even 2 years after diagnosis. Fatigue in breast cancer patients, the so‐far most studied group, is in the lowest range among all entities, suggesting that the extent of fatigue is still insufficiently determined. Entity‐specific problems might need to be considered in the treatment of fatigue.

Landscape of Health-Related Quality of Life in Patients With Early-Stage Pancreatic Cancer Receiving Adjuvant or Neoadjuvant Chemotherapy: A Systematic Literature Review

OBJECTIVES

Pancreatic resection is associated with postoperative morbidity and reduced quality of life (QoL). A systematic literature review was conducted to understand the patient-reported outcome measure (PROM) landscape in early-stage pancreatic cancer (PC).

METHODS

Databases/registries (through January 24, 2019) and conference abstracts (2014-2017) were searched. Study quality was assessed using the Newcastle-Ottawa Scale/Cochrane risk-of-bias tool. Searches were for general (resectable PC, adjuvant/neoadjuvant, QoL) and supplemental studies (resectable PC, European Organisation for Research and Treatment of Cancer QoL Questionnaire [QLQ] - Pancreatic Cancer [PAN26]).

RESULTS

Of 750 studies identified, 39 (general, 22; supplemental, 17) were eligible: 32 used QLQ Core 30 (C30) and/or QLQ-PAN26, and 15 used other PROMs. Baseline QLQ-C30 global health status/QoL scores in early-stage PC were similar to all-stage PC reference values but lower than all-stage-all-cancer values. The QoL declined after surgery, recovered to baseline in 3 to 6 months, and then generally stabilized. A minimally important difference (MID) of 10 was commonly used for QLQ-C30 but was not established for QLQ-PAN26.

CONCLUSIONS

In early-stage PC, QLQ-C30 and QLQ-PAN26 are the most commonly used PROMs. Baseline QLQ-C30 global health status/QoL scores suggested a high humanistic burden. Immediately after surgery, QoL declined but seemed stable over the longer term. The QLQ-C30 MID may elucidate the clinical impact of treatment on QoL; MID for QLQ-PAN26 needs to be established.

A systematic review and meta-analysis on the quality of life after hepatic resection

BACKGROUND

Quality of life (QoL) after hepatic resection is a pertinent issue that has been poorly studied. The aim of this study was to compare changes in QoL before and after hepatic resection.

METHODS

A systematic review was performed using Medline, EMBASE, and the Cochrane library. Whenever possible, pooled mean differences of survey scores pre- and post-operatively were calculated.

RESULTS

22 studies were included comprising a total of 1785 participants. Using the EORTC-QLQ 30C survey, patients with benign disease tend to have better QoL post-surgery than those with malignant disease. There were post-operative improvements in the following FACT-HEP domains: physical at 9 months (MD 3.14, 95%CI 2.70 to 3.58, P < 0.001), social and family at 3 (MD 1.45, 95%CI 0.12 to 2.77, p = 0.030), 6 (MD 1.12, 95%CI 0.21 to 2.04, p = 0.020), 9 (MD 0.66, 95%CI 0.03 to 1.28, p = 0.040), and 12 (MD 0.58, 95%CI 0.12 to 1.03, p = 0.010) months, emotional at 9 (P < 0.001) and 24 months (P < 0.001), hepatobiliary at 24 months (p < 0.001), and global health status at 9 months (p = 0.002).

CONCLUSION

QoL scores tend to deteriorate post-surgery, but recover to baseline in the long-term at 9-months. Patients with malignant disease, and those who underwent major hepatectomy, have poorer QoL scores.

Treatment and survival rates of stage IV pancreatic cancer at VA hospitals: a nation-wide study

Background

Metastatic pancreatic cancer (MPC) is associated with an extremely high mortality. Current NCCN guidelines recommend systemic therapy, as it is superior to best supportive care. Undertreatment of MPC continues to be an issue. Recent treatment and survival data of MPC in Veterans' Affairs' (VA) hospitals have not been published. The relationship between MPC treatment and survival and the American College of Surgeons' (ACS) Committee on Cancer (CoC) accreditation in VA hospitals has not been studied.

Methods

Nationwide data from the National Veterans Affairs Cancer Cube Registry was analyzed. In total, 6,775 patients were diagnosed with MPC between 2000 and 2014. CoC accreditation of each VA hospital was obtained using the ACS website.

Results

MPC constitutes 52.31% of all pancreatic cancer diagnosed (6,775/12,951 cases). The near totality was men (97.44%). The above 70 years age group and the 60-70 years age group were the most common ages at diagnosis with 39.39% and 38.02% respectively. The proportion of early-onset pancreatic cancer (EOPC) was 2.84%. When compared to all stages of pancreatic cancer, stage IV pancreatic cancer had a lower proportion of cancer originating from the head of the pancreas (39.33% versus 50.63%) and more originating from the tail (17.99% versus 13.39%). Tumors originating from head of the pancreas are more likely to cause biliary symptoms and thus are more likely to be caught at an earlier stage. Overall, treatment rate in the VA at the national level with first-line chemotherapy was 37.61%. The rate of treatment over the years has increased in a linear fashion from 33.01% in 2000 to 41.95% in 2014. This has corresponded with an increase of 1-5 years survival of 9.29% in 2000 to 22.99% in 2014 and 5-10 years survival from 0.96% in 2000 to 6.00% in 2012. Treatment rates in CoC-accredited and non-CoC accredited VA hospitals were similar (38.94% and 38.12%, respectively). Survival rates in CoC-accredited and non-COC accredited VAs were similar with a 1-5 years survival rate of 8.89% and 8.57%, respectively.

Conclusions

Treatment and survival of MPC have risen significantly in the past decade at VA hospitals. CoC accreditation is not associated with a change in treatment or survival rates.

Association of time interval between cancer diagnosis and initiation of palliative chemotherapy with overall survival in patients with unresectable pancreatic cancer

INTRODUCTION

Palliative chemotherapy is the standard treatment for patients with unresectable pancreatic cancer. Whether the early initiation of palliative chemotherapy is associated with a favorable survival outcome for these patients is not known. This study aimed to analyze the association of the time interval between cancer diagnosis and initiation of palliative chemotherapy with survival outcome in patients with pancreatic cancer.

METHOD

A total of 838 patients with unresectable pancreatic cancer who underwent palliative chemotherapy from 2010 to 2016 at 4 institutions in Taiwan were retrospectively enrolled. All patients were categorized according to time interval between cancer diagnosis and initiation of palliative chemotherapy for comparison of the survival outcome.

RESULT

The median time interval was 14 days (range, 0 to 163 days) in our patient cohort. Accordingly, 22%, 29%, and 49% of the patients underwent palliative chemotherapy within 1, 1 to 2, and >2 weeks after cancer diagnosis, respectively. The survival outcome had no statistical difference among these 3 patient groups. Subgroup analyses revealed that patients with the time interval ≤2 weeks exhibited poorer survival outcome than those with the time interval >2 weeks if they initially presented with jaundice (6.1 months vs 8.4 months, P = 0.029). In contrast, patients with the time interval ≤2 weeks revealed a better survival outcome than those with the time interval >2 weeks if they initially presented with pain (8.0 vs 6.3 months, P = 0.014).

CONCLUSION

In our study, time interval between cancer diagnosis and the initiation of palliative chemotherapy >2 weeks was not associated with a poorer survival outcome for patients with unresectable pancreatic cancer. Our result might help clinicians to clarify that early initiation of palliative chemotherapy might provide survival benefit for patients who present with tumor pain, but not for those who present with jaundice.

Determinants of quality of life among Malaysian cancer patients: a cross-sectional study

BACKGROUND

Cancer is a serious public health problem not only in Malaysia, also worldwide. The aim of this study was to determine the determinants of quality of life (QOL) among cancer patients in Peninsular Malaysia.

METHODS

A cross sectional study was conducted among 2120 cancer patients in Peninsular Malaysia, between April 2016 to January 2017. All cancer patients aged 18 years old and above, Malaysian citizens and undergoing cancer treatment at government hospitals were approached to participate in this study and requested to complete a set of validated questionnaires. Inferential statistical tests such as t-test and one-way ANOVA were used to determine the differences between demographic variables, physical effects, clinical factors, psychological effects and self-esteem with the quality of life of cancer patients. Predictor(s) of quality of life were determined by using Multivariate linear regression models.

RESULT

A total 1620 out of 2120 cancer patients participated in this study, giving a response rate of 92%. The majority of cancer patients were female 922 (56.9%), Malays 1031 (63.6%), Muslim 1031 (63.6%), received chemotherapy treatment 1483 (91.5%). Overall, 1138 (70.2%) of the patients had depression and 1500 (92.6%) had anxiety. Statistically significant associations were found between QOL and clinical factors, physical side effects of cancer, psychological effects and self-esteem (p < 0.05). However, among socio-demographics only age, race, religion, working status were significantly associated with QOL. Based on the multivariate regression analysis, the main predictors of QOL among cancer patients in Malaysia were age, self-esteem as positive predictors, and Indian race, nausea, fatigue, hair loss, bleeding as negative predictors.

CONCLUSION

The findings of this study provide a scientific basis to develop a comprehensive program for improving quality of life of cancer patients in Malaysia.

Implication of 4E-BP1 protein dephosphorylation and accumulation in pancreatic cancer cell death induced by combined gemcitabine and TRAIL

Pancreatic cancer cells show varying sensitivity to the anticancer effects of gemcitabine. However, as a chemotherapeutic agent, gemcitabine can cause intolerably high levels of toxicity and patients often develop resistance to the beneficial effects of this drug. Combination studies show that use of gemcitabine with the pro-apoptotic cytokine TRAIL can enhance the inhibition of survival and induction of apoptosis of pancreatic cancer cells. Additionally, following combination treatment there is a dramatic increase in the level of the hypophosphorylated form of the tumour suppressor protein 4E-BP1. This is associated with inhibition of mTOR activity, resulting from caspase-mediated cleavage of the Raptor and Rictor components of mTOR. Use of the pan-caspase inhibitor Z-VAD-FMK indicates that the increase in level of 4E-BP1 is also caspase-mediated. ShRNA-silencing of 4E-BP1 expression renders cells more resistant to cell death induced by the combination treatment. Since the levels of 4E-BP1 are relatively low in untreated pancreatic cancer cells these results suggest that combined therapy with gemcitabine and TRAIL could improve the responsiveness of tumours to treatment by elevating the expression of 4E-BP1.

β-catenin is required for taste bud cell renewal and behavioral taste perception in adult mice

Taste stimuli are transduced by taste buds and transmitted to the brain via afferent gustatory fibers. Renewal of taste receptor cells from actively dividing progenitors is finely tuned to maintain taste sensitivity throughout life. We show that conditional β-catenin deletion in mouse taste progenitors leads to rapid depletion of progenitors and Shh⁺ precursors, which in turn causes taste bud loss, followed by loss of gustatory nerve fibers. In addition, our data suggest LEF1, TCF7 and Wnt3 are involved in a Wnt pathway regulatory feedback loop that controls taste cell renewal in the circumvallate papilla epithelium. Unexpectedly, taste bud decline is greater in the anterior tongue and palate than in the posterior tongue. Mutant mice with this regional pattern of taste bud loss were unable to discern sweet at any concentration, but could distinguish bitter stimuli, albeit with reduced sensitivity. Our findings are consistent with published reports wherein anterior taste buds have higher sweet sensitivity while posterior taste buds are better tuned to bitter, and suggest β-catenin plays a greater role in renewal of anterior versus posterior taste buds.

By remaining relatively constant throughout adult life, the sense of taste helps keep the body healthy. However, taste perception can be disrupted by various environmental factors, including cancer therapies. Here, we show that Wnt/β-catenin signaling, a pathway known to control normal tissue maintenance and associated with the development of cancers, is required for taste cell renewal and behavioral taste sensitivity in mice. Our findings are significant as they suggest that chemotherapies targeting the Wnt pathway in cancerous tissues may cause taste dysfunction and further diminish the quality of life of patients.

Pancreatic cancer survivors' preferences, barriers, and facilitators related to physical activity and diet interventions

PURPOSE

To conduct a telephone survey establishing pancreatic cancer survivors' level of interest in, preferences for, and perceived barriers and facilitators to participating in exercise and diet intervention programming. These data will inform the development of such interventions for newly-diagnosed patients.

METHODS

Seventy-one survivors treated for resectable pancreatic adenocarcinoma from October 2011 to August 2014 were identified through an institutional cancer registry and contacted via telephone. A telephone survey was conducted to query survivors' level of interest in, preferences for, and perceived barriers and facilitators to participating in an exercise and dietary intervention program shortly after disease diagnosis. Acceptability of a technology-based visual communication (e.g., Skype™, FaceTime®) intervention was also assessed.

RESULTS

Fifty participants completed the survey (response rate 71.8 %). Over two-thirds of participants reported interest in exercise and diet intervention programming. Over half reported comfort with a technology-delivered visual communication intervention. Barriers to participation included older age and physical, personal, and emotional problems. The most common facilitator was program awareness. Outcomes for future research important to participants were supportive care and quality of life.

CONCLUSIONS

Most pancreatic cancer patients are interested in exercise and diet interventions shortly after diagnosis; however, some barriers to program participation exist.

IMPLICATIONS FOR CANCER SURVIVORS

Future research and intervention planning for pancreatic cancer survivors should focus on developing messaging and strategies that provide support for survivorship outcomes, increase survivor awareness, address lack of familiarity with technology, reduce fears about potential barriers, and help survivors overcome these barriers. In so doing, survivorship needs can be better met and quality of life improved in this understudied population.

Beyond survivorship? A discursive analysis of how people with pancreatic cancer negotiate identity transitions in their health

We explored how people negotiate, and respond to, identity transitions following a diagnosis of pancreatic cancer. Interviews with 19 people with pancreatic cancer were analysed using thematic discourse analysis. While discursively negotiating two transitions, 'moving from healthy to ill' and 'moving from active treatment to end-of-life care', participants positioned themselves as 'in control', 'optimistic' and managing their health and illness. In the absence of other discourses or models of life post-cancer, many people draw on the promise of survival. Moving away from 'survivorship' may assist people with advanced cancer to make sense of their lives in a short timeframe.

Quality of life across chemotherapy lines in patients with advanced colorectal cancer: a prospective single-center observational study

BACKGROUND

Palliative chemotherapy in patients with nonresectable advanced colorectal carcinoma is performed to prolong survival, alleviate tumor-associated symptoms, and maintain or improve health-related quality of life (HRQOL). In this prospective single-center observational study, we assessed HRQOL across the various lines of palliative chemotherapy.

METHODS

HRQOL data were acquired using the EORTC Quality of Life Questionnaire-C30 (QLQ-C30) questionnaire. The first assessment was performed at the beginning of each chemotherapy line, the second after three cycles, and the third at the end of chemotherapy. Further assessments were conducted during checkups every 3 months in our outpatient unit.

RESULTS

In total, 100 consecutive patients with colorectal carcinoma (mean age 66.4 years; 60 % men) treated with palliative chemotherapy were recruited. Generally, QOL deteriorated constantly across time. Physical functioning, fatigue, pain, dyspnea, and appetite worsened steadily from first-line chemotherapy to the later treatment phase. Global QOL, emotional functioning, and role functioning improved slightly after the end of first-line chemotherapy, deteriorated during second-line chemotherapy to the level of first-line chemotherapy, and further deteriorated in the later treatment phases. In additional analyses, we found the largest differences between patients with and without a treatment response for pain (19.0 vs. 37.2 points) and appetite loss (17.4 vs. 32.7 points).

CONCLUSION

The individual QOL domains deteriorated constantly across time. Our data indicate that patients undergoing first- and second-line palliative chemotherapy experience stabilization of global QOL and psychosocial symptoms. We also found that unselected patients who achieved a treatment response had a lower symptom burden and better QOL than did patients with progressive disease.

Phase II clinical trial of ex vivo-expanded cytokine-induced killer cells therapy in advanced pancreatic cancer

Second-line chemotherapy in patients with gemcitabine-refractory advanced pancreatic cancer has shown disappointing survival outcomes due to rapid disease progression and performance deterioration. The aim of this phase II trial was to evaluate the efficacy and safety of adoptive immunotherapy using ex vivo-expanded, cytokine-induced killer (CIK) cells in gemcitabine-refractory advanced pancreatic cancer. Patients with advanced pancreatic cancer who showed disease progression during gemcitabine-based chemotherapy were enrolled in this study. For generation of CIK cells, peripheral blood samples were collected from each patient and cultured with anti-CD3 monoclonal antibody and IL-2. Patients received CIK cells intravenously 10 times, every week for 5 weeks and then every other week for 10 weeks. Twenty patients were enrolled between November 2009 and September 2010. The disease control rate was 25 % (4/16 patients). The median progression-free survival (PFS) was 11.0 weeks (95 % CI 8.8-13.2), and the median overall survival (OS) was 26.6 weeks (95 % CI 8.6-44.6). Grade 3 toxicities included general weakness in two patients and thrombocytopenia in one patient. Grade 4 hematologic or non-hematologic toxicity was not observed. Patients showed improvement in pancreatic pain, gastrointestinal distress, jaundice, body image alterations, altered bowel habits, health satisfaction, and sexuality when assessing quality of life (QoL). Adoptive immunotherapy using CIK cells showed comparable PFS and OS to survival data of previous trials that assessed conventional chemotherapies while maintaining tolerability and showing encouraging results in terms of patient QoL in gemcitabine-refractory advanced pancreatic cancer (clinicalTrials.gov number NCT00965718).

Quality of life in cancer patients undergoing chemotherapy in a tertiary care center in malwa region of punjab

OBJECTIVE

The objective of this prospective, non-interventional, 4-month observational study was to analyze and compare patient-reported quality of life (QOL) and their physical/psychosocial symptom burden during their respective chemotherapy sessions.

MATERIALS AND METHODS

A prospective and descriptive study was carried out jointly by Pharmacology and Oncology Departments of a tertiary care center in Malwa region of Punjab. The data collection was performed by administering validated questionnaire/response after taking informed consent.

RESULTS

A total of 131 cancer patients were recruited with the mean age of 49.05 ± 14.35 (SD (standard deviation)) years. As per the QOL scoring of Global Health Status (GHS) and four items of symptom scale, that is, insomnia, pain, appetite loss, and constipation, and financial difficulties attained a significance difference. GHS significantly improved in group three as compared to group one, indicating that the patient's overall health/QOL improved as the chemotherapy session progressed.

CONCLUSION

Although QOL scoring system did not show significant improvement in all areas (except insomnia, pain, appetite loss, constipation, and financial difficulties) with reference to their respective chemotherapy cycles, but a judicious diagnosis with an appropriate treatment including chemotherapy may lessen the negative perception of cancer as a deadly and fatal disease in our rural population.

New and emerging treatment options for biliary tract cancer

Biliary tract cancer (BTC) is a group of relatively rare tumors with a poor prognosis. The current standard of care consists of doublet chemotherapy (platinum plus gemcitabine); however, even with cytotoxic therapy, the median overall survival is less than 1 year. The genetic basis of BTC is now more clearly understood, allowing for the investigation of targeted therapy. Combinations of doublet chemotherapy with antiepidermal growth factor receptor agents have provided modest results in Phase II and Phase III setting, and responses with small molecule inhibitors are limited. Moving forward as we continue to characterize the genetic hallmarks of BTC, a stepwise, strategic, and cooperative approach will allow us to make progress when developing new treatments.
