Mast cells are commonly found in pancreatic ductal adenocarcinoma (PDAC), yet their role in the disease remains uncertain. Although mast cells have been associated with depression in several diseases, their connection to PDAC in this context remains unclear. This study explored the correlation between mast cells and psychosocial stress in patients with PDAC. Prior to surgery, 40 patients with PDAC (n = 29 primary resected, n = 11 neoadjuvant treated) completed four questionnaires assessing stress and quality of life. Immunostaining was performed on the resected tumor tissue. Spearman analysis was employed to correlate mast cells with distress and neuropeptides serotonin and beta-endorphin serum and tissue levels. Patients with PDAC exhibited elevated levels of distress and worry. Lower number of mast cells within the tumor correlated with greater psychological burden. Among primary resected patients, mast cell count moderately correlated with joy and inversely with worries. Following neoadjuvant chemotherapy, strong inverse correlation was observed between anxiety, depression, and mast cell quantity. No correlation was found between mast cells and serotonin or beta-endorphin levels. In summary, mast cell presence inversely correlates with psychosocial stress, suggesting a link between immune cells and psychological well-being in pancreatic cancer. Targeting mast cells might offer therapeutic avenues for addressing cancer-induced depression and anxiety., (© 2024. The Author(s).)

Background & Aims: Genetic testing uptake for cancer susceptibility in family members of patients with cancer is suboptimal. Among relatives of patients with pancreatic ductal adenocarcinoma (PDAC), The GENetic Education, Risk Assessment, and TEsting (GENERATE) study evaluated 2 online genetic education/testing delivery models and their impact on patient-reported psychological outcomes., Methods: Eligible participants had ≥1 first-degree relative with PDAC, or ≥1 first-/second-degree relative with PDAC with a known pathogenic germline variant in 1 of 13 PDAC predisposition genes. Participants were randomized by family, between May 8, 2019, and June 1, 2021. Arm 1 participants underwent a remote interactive telemedicine session and online genetic education. Arm 2 participants were offered online genetic education only. All participants were offered germline testing. The primary outcome was genetic testing uptake, compared by permutation tests and mixed-effects logistic regression models. We hypothesized that Arm 1 participants would have a higher genetic testing uptake than Arm 2. Validated surveys were administered to assess patient-reported anxiety, depression, and cancer worry at baseline and 3 months postintervention., Results: A total of 424 families were randomized, including 601 participants (n = 296 Arm 1; n = 305 Arm 2), 90% of whom completed genetic testing (Arm 1 [87%]; Arm 2 [93%], P = .014). Arm 1 participants were significantly less likely to complete genetic testing compared with Arm 2 participants (adjusted ratio [Arm1/Arm2] 0.90, 95% confidence interval 0.78-0.98). Among participants who completed patient-reported psychological outcomes questionnaires (Arm 1 [n = 194]; Arm 2 [n = 206]), the intervention did not affect mean anxiety, depression, or cancer worry scores., Conclusions: Remote genetic education and testing can be a successful and complementary option for delivering genetics care.

Background: The timing and the dose of Advanced Care Planning in patients with pancreatic ductal adenocarcinoma undergoing curative-intent resection are generally dictated by the surgeon performing the operation., Methods: A qualitative investigation using 1:1 interviews with 40 open-ended questions was conducted with a convenience sample of 10 high-volume pancreatic surgeons from across the country. The grounded theory approach was used for data analysis., Results: A total of 10 interviews were conducted with expert pancreatic surgeons-6 males and 4 females. During preoperative counseling, all surgeons attempt to motivate patients by emphasizing hope, optimism, and the fact that surgery offers the only opportunity for cure. All surgeons discuss the possibility of recurrence as well as postoperative complications; however, a majority perceived that patients do not fully appreciate the likelihood of recurrence or postoperative complications. All surgeons acknowledged the importance of end-of-life conversations when death is imminent. Seventy percent of surgeons had mixed opinions regarding benefits of preoperative Advanced Care Planning in the preoperative setting, while 20% felt it was definitely beneficial, particularly that delivery of care aligned with patient goals. All surgeons emphasized that Advanced Care Planning should be led by a physician who both knows the patient well and understands the nuances of pancreatic ductal adenocarcinoma management. Most common barriers to in-depth Advanced Care Planning discussion reported by surgeons include taking away hope, lack of time, and concern for sending "mixed messages.", Conclusion: We identified that surgeons experience a fundamental tension between promoting realistic long-term goals and expectations versus focusing on hope and enabling an overly optimistic perception of prognosis., (Copyright © 2021 Elsevier Inc.

Purpose: National Comprehensive Cancer Network guidelines for germline genetic testing have included pancreatic cancer in the context of additional family cancer history for many years but this was not recommended for patients with pancreatic ductal adenocarcinoma (PDAC) independent of a family history until 2019. This hypothesis-generating study reports the results from multigene panel testing for PDAC patients at an academic medical center., Patients and Methods: This prospective longitudinal feasibility study examined responses to genetic counseling and multigene panel testing among PDAC and breast or ovarian cancer (BrOv) patients between October 2016 and November 2017. Pre- and post-test surveys assessed perceptions of genetic risk and testing, recall, comprehension, and emotional reactions to results using open-ended and closed-ended items., Results: Forty-six BrOv and 33 PDAC patients were enrolled, and 44 BrOv and 31 PDAC participants underwent genetic testing. Seven pathogenic variants were identified in six BrOv participants (13.6%), and three pathogenic variants were identified in three PDAC participants (9.7%). The majority of both cohorts expressed similar attitudes about the importance of genetic testing for their personal and family medical management and expressed accurate understanding of implications of their results. Although sample size was small, there were no significant differences between the BrOv and PDAC cohorts for positive or negative emotions., Conclusion: This study points to high rates of positive emotions and low rates of negative emotions following genetic test results, suggesting that the emotional reactions to genetic test results are similar for patients with BrOv and PDAC, despite poor prognosis with PDAC diagnoses. Because of the unique needs of the PDAC population following diagnosis, a multidisciplinary approach to germline genetic testing following diagnosis may result in best patient and family member outcomes., (© 2021 by American Society of Clinical Oncology.)

In high-risk individuals participating in a pancreatic cancer surveillance program, worrisome features warrant for intensified surveillance or, occasionally, surgery. Our objectives were to determine the patient-reported burden of intensified surveillance and/or surgery, and to assess post-operative quality of life and opinion of surgery. Participants in our pancreatic cancer surveillance program completed questionnaires including the Cancer Worry Scale (CWS) and the Hospital Anxiety and Depression Scale (HADS). For individuals who underwent intensified surveillance, questionnaires before, during, and ≥ 3 weeks after were analyzed. In addition, subjects who underwent intensified surveillance in the past 3 years or underwent surgery at any time, were invited for an interview, that included the Short-Form 12 (SF-12). A total of 31 high-risk individuals were studied. During the intensified surveillance period, median CWS scores were higher (14, IQR 7), as compared to before (12, IQR 9, P = 0.007) and after (11, IQR 7, P = 0.014), but eventually returned back to baseline (P = 0.823). Median HADS scores were low: 5 (IQR 6) for anxiety and 3 (IQR 5) for depression, and they were unaffected by the intensified surveillance period. Of the 10 operated patients, 1 (10%) developed diabetes and 7 (70%) pancreatic exocrine insufficiency. The interviews yielded median quality-of-life scores comparable to the general population. Also, after surgery, patients' attitudes towards surveillance were unchanged (5/10, 50%) or became more positive (4/10, 40%). Although patients were aware of the (sometimes benign) pathological outcome, when asked if surgery had been justified, only 20% (2/10) disagreed, and all would again have chosen to undergo surgery. In conclusion, in individuals at high risk for pancreatic cancer, intensified surveillance temporarily increased cancer worries, without affecting general anxiety or depression. Although pancreatic surgery led to substantial co-morbidity, quality of life was similar to the general population, and surgery did not negatively affect the attitude towards surveillance.

Background: The primary aim of this study was to assess if patients with potentially resectable ductal adenocarcinoma (PDAC) of the head of the pancreas would choose a Whipple procedure versus palliative chemotherapy., Methods: A cohort of adults with radiological resectable PDAC was enrolled at a tertiary Canadian teaching hospital. Participants were informed about treatment options, expected outcomes, and adverse events using data from the most recent scientific literature. Probability trade-off (PTO) was used to elicit treatment preferences., Results: Surgery was preferred by all participants except one (96.7% vs. 3.3%; P = 0.0001). For 90% of participants preferring surgery, the main reason was the hope of being cured (P = 0.001). If the risk of perioperative mortality was higher than 57%, the risk of perioperative morbidity higher than 85% and the survival benefit was less than 4 months, half of the participants preferred palliative chemotherapy. The likelihood of needing blood transfusions, the length of hospital stay, and long-term consequences such as diabetes or pancreatic exocrine insufficiency were negligible concerns to participants., Conclusions: Informed patients with early-stage PDAC prefer resection over palliative chemotherapy. The dominating factor influencing their decision is the hope of a cure that overshadow the risks of complications, mortality and recurrent disease., (Copyright © 2019 International Hepato-Pancreato-Biliary Association Inc.

Objectives: To compare fatigue and quality of life (QOL) between individuals with pancreatogenic diabetes after total pancreatectomy (TP) and pancreaticoduodenectomy (PD)., Sample & Setting: 50 individuals (14 after TP and 36 after PD) were recruited from a pancreatic surgical outpatient department. A final sample of 39 matched individuals (13 after TP and 26 after PD) were included in the final analysis., Methods & Variables: A comparative cross-sectional approach was used. Variables were fatigue and QOL. The Fatigue Symptom Inventory and European Organisation for the Research and Treatment of Cancer Quality-of-Life Questionnaire-Core 30 were used. Data went through propensity score one-to-two matching. Generalized estimating equation was used to compare fatigue and QOL., Results: The groups showed no statistically significant difference in fatigue intensity and overall QOL. The TP group had significantly longer fatigue duration, perceived higher interference of functioning, lower physical function, and a higher level of insomnia., Implications for Nursing: Future studies with a larger sample and longitudinal design will help identify the trajectory of fatigue and QOL in individuals with pancreatogenic diabetes post-TP and PD.

Data regarding management of frail patients with pancreatic ductal adenocarcinoma practice is currently very scarce. Randomized clinical trials usually exclude these subgroup of patients and the majority of the publications only consider chronological age and ECOG performance status for their classification. Therefore, the current available data do not reflect daily clinical practice. Only data from a phase two study (FRAGANCE study), designed to select a tolerable dose-schedule of nab-placitaxel + gemcitabine (Phase one) and to evaluate the efficacy of the selected regimen (Phase two) in patients with ECOG-2 and previously untreated advanced PDAC, are currently available. Management of these particular patients is exceedingly complex and requires collaboration of multidisciplinary teams and intensive support treatment. This article reviews the literature available regarding the management of the so-called frail patients and provide guidance for chemotherapy as well as supportive care treatments., (Copyright © 2018 Elsevier Inc.

Palliative and supportive care holds a major place in pancreatic ductal adenocarcinoma (PDAC) management. It aims to prevent and reduce symptoms and hospital admissions, while ensuring optimal health-related quality of life (HRQoL), which has been reported to be correlated with overall survival in PDAC. Best supportive care includes non-specific treatment of pain, anxiety and depression, chemotherapy-related toxicities, as well as thromboembolic disease treatment and prevention in high-risk patients. Moreover, nutrition and physical activity interventions are receiving increasing attention as they are crucial to optimize treatment tolerance and efficacy. Of note, they require adaptation to the specificities of PDAC setting and stage of the disease. In this review, we propose an overview of palliative and supportive care interventions in PDAC, with a highlight on nutritional and physical activity management., (Copyright © 2019 Elsevier Masson SAS.

Background: The NAPOLI-1 study (NCT01494506) reported that liposomal irinotecan plus 5-fluorouracil and leucovorin (nal-IRI+5-FU/LV) improved overall survival vs 5-FU/LV with manageable toxicity in patients with metastatic pancreatic adenocarcinoma previously treated with gemcitabine-based therapy. Yet, clinicians need treatment strategies that also maintain the patient's health-related quality of life (HRQOL). Here, we report the HRQOL data., Methods: Patients completed the European Organisation for Research and Treatment of Cancer QOL core questionnaire C30 (EORTC QLQ-C30) at baseline, every 6 weeks, and at 30 days after discontinuation of study treatment. Patient-reported outcomes (PROs) were scored according to EORTC guidelines. nal-IRI+5-FU/LV HRQOL was compared with 5-FU/LV. The PRO population comprised intent-to-treat patients who completed baseline and at least one subsequent assessment on the EORTC QLQ-C30. Data were also analysed for missingness., Results: Of 236 patients in the intent-to-treat population, 128 (54.2%) comprised the PRO population (71 in the nal-IRI+5-FU/LV arm; 57 the in 5-FU/LV arm). Of the remaining 108 patients (45.8%) not included in the PRO population, most progressed rapidly, making participation difficult. Median change from baseline was ≤10 points at weeks 6 and 12 in global health status or functional and symptom scale scores, except for fatigue, which deteriorated by 11.1 points with nal-IRI+5-FU/LV but did not change vs 5-FU/LV. The proportion of patients whose HRQOL improved or deteriorated was not significantly different between the arms., Conclusion: In the NAPOLI-1 study, HRQOL was maintained with nal-IRI+5-FU/LV in patients with metastatic pancreatic adenocarcinoma previously treated with a gemcitabine-based regimen, while survival was significantly extended., (Copyright © 2018 The Authors.

The prevalence of major depressive disorder (MDD) in pancreatic cancer (PC) has been reported up to 7 times higher than the general population. Despite repeated studies that show worse quality of life, survival outcomes, and treatment compliance in cancer patients with depression, baseline antidepressant use ranges from 15% to 27%. A meta-analysis of 6 prospective trials specific to PC estimates that 43% of patients with PC experience depression after diagnosis. This is especially alarming in patients with PC, who may experience a prodrome of symptoms including depression and loss of drive. In fact, this prodrome of symptoms may very well be due to an overexpression of indoleamine 2,3-dioxgenase, an enzyme in the kynurenine pathway that leads to serotonin depletion and the buildup of cytotoxic metabolites in the brain. In this literature review, we outline all previous studies pertinent to PC and depression, as well as the molecular underpinnings that may contribute to states of depression, and report on previous randomized control trials in cancer populations that investigate the use of antidepressants to treat depressive symptoms and improve quality of life both prophylactically and after the onset of major depressive disorder. In addition, we detail a case report outlining the precipitous decline in health in 1 patient with PC and depression.

Background: Quality of life (QOL) is impaired in pancreatic cancer patients. Our aim was to investigate the determinants and prognostic value of QOL after diagnosis in a hospital-based cohort of racially/ethnically diverse patients with pancreatic ductal adenocarcinoma (PDAC)., Patients and Methods: QOL was prospectively assessed using the Short Form-12 in 2478 PDAC patients. The Physical Component Summary (PCS) and Mental Component Summary (MCS) were categorised into tertiles based on their distribution. Ordered logistic regression was adopted to compare the risk of having lower PCS and MCS by patient sociodemographic and clinical characteristics. The association of PCS and MCS with mortality was assessed by Cox regression., Results: Compared with non-Hispanic whites, Hispanics were at significantly higher risk of having lower PCS (odds ratio [95% CI], 1.69 [1.26-2.26]; P < 0.001) and lower MCS (1.66 [1.24-2.23]; P < 0.001). Patients diagnosed with stage III (1.80 [1.10-2.94]; P = 0.02) and stage IV (2.32 [1.50-3.59]; P < 0.001) PDAC were more likely to have lower PCS than stage I patients. Other determinants of QOL included sex, age, drinking, smoking, education level, comorbidities and time since diagnosis. The low tertile of PCS (hazard ratio [95% CI], 1.94 [1.72-2.18]; P < 0.001) and MCS (1.42 [1.26-1.59]; P < 0.001) were each related to poor prognosis. Similar results were found for non-Hispanic whites as compared with African-Americans/Hispanics/others., Conclusion: QOL after diagnosis is a significant prognostic indicator for patients with PDAC. Multiple factors determine QOL, suggesting possible means of intervention to improve QOL and outcomes of PDAC patients., (Copyright © 2017. Published by Elsevier Ltd.)

Pancreatic ductal adenocarcinoma (PDAC) carries a poor prognosis, and as such, a focus on quality of life is vital. This review will discuss various aspects of quality of life in patients with PDAC and their treatment. Pancreatic exocrine and endocrine insufficiency may result in issues related to nutrition, and pain and fatigue are other common symptoms, and may be managed with pharmaceutical or nonpharmaceutical methods. It has also been reported that low mood is a particular problem for patients with PDAC compared to patients with other cancers; however, the data supporting this is inconsistent. Data regarding improvements in quality of life in patients with PDAC receiving chemotherapy is also reviewed, which in some cases suggests a benefit to chemotherapy, particularly in the presence of a radiological response. Furthermore, the importance of early palliative care is discussed and the benefits reported including improved quality of life and mood, reduced aggressive interventions at the end of life and improved survival. Areas for future development may include increased use of quality of life as a trial outcome and the use of patient-reported outcomes to improve symptomatic care of patients, and particularly in those receiving active systemic treatment., (Copyright © 2018 Elsevier Inc.

Objectives: This study aims to evaluate the well-being of patients with main duct intraductal papillary mucinous neoplasms (MD-IPMNs) or mixed type IPMNs (mixed-IPMNs) of the pancreas., Methods: Twenty-two patients with MD/mixed-IPMNs of the pancreas were studied, and an equal number of patients having branch duct IPMNs (BD-IPMNs) were used as controls. The short form (SF) -12 Health Survey, State Trait Anxiety Inventory Y-1 and Y-2, General Health Questionnaire, and Beck Depression Inventory II were used to evaluate the quality of life once a year for 2 consecutive years., Results: At basal evaluation, the SF-12 Health Survey questionnaire administered to the 44 patients showed that the values of the physical component and mental component scores were similar between the 2 groups of patients studied. The State Trait Anxiety Inventory Y-1 and Y-2, General Health Questionnaire, and Beck Depression Inventory II scores were also similar in the 2 groups at basal evaluation. No differences were found between MD/mixed-IPMNs and BD-IPMNs at the 1-year and the 2-year evaluations., Conclusions: The well-being of patients with MD/mixed-IPMNs did not differ as compared with patients with BD-IPMNs.

Introduction: Survival for pancreatic ductal adenocarcinoma (PDAC) is relatively short even after complete resection. Pancreaticoduodenectomy (PD) carries a high risk for postoperative morbidity, and the effect on quality of life (QoL) is unclear. We aimed to study QoL in PDAC patients undergoing PD., Patients and Methods: Sixty patients with suspected PDAC and planned PD were asked to complete EORTC QoL questionnaires QLQ-C30 and QLQ-PAN26 preoperatively and at 3-6-12-18-24 months postoperatively., Results: 47 PDAC patients who underwent PD (66 (21-84) years, 53% men) were included. Follow-up was completed by 81% (6 months) and 45% (24 months) post-PD. Compared to preoperative level, QoL tended to improve or remained the same in 63% during the follow-up. At three months after PD patients had less hepatic symptoms (decreased by 100%; p < 0.001), pancreatic pain and sexuality symptoms tended to decrease by 33% and global and functional QoL tended to slightly improve. These parameters remained at the achieved level during the longer follow-up. A temporary rising tendency was seen in digestive symptoms at three months but this later reverted to the preoperative level. More altered bowel movements and sexuality symptoms tended to arise during the longer follow-up. A negative correlation was found between reported financial difficulties and length of survival., Conclusions: PD does not worsen the QoL in most of the patients with PDAC. The potentially beneficial effect on QoL is apparent already at three months after surgery. This information may be helpful for the clinician and patient, when deciding on the treatment for PDAC., (Copyright © 2017 IAP and EPC. Published by Elsevier B.V. All rights reserved.)

The genome of pancreatic ductal adenocarcinoma (PDAC) frequently contains deletions of tumour suppressor gene loci, most notably SMAD4, which is homozygously deleted in nearly one-third of cases. As loss of neighbouring housekeeping genes can confer collateral lethality, we sought to determine whether loss of the metabolic gene malic enzyme 2 (ME2) in the SMAD4 locus would create cancer-specific metabolic vulnerability upon targeting of its paralogous isoform ME3. The mitochondrial malic enzymes (ME2 and ME3) are oxidative decarboxylases that catalyse the conversion of malate to pyruvate and are essential for NADPH regeneration and reactive oxygen species homeostasis. Here we show that ME3 depletion selectively kills ME2-null PDAC cells in a manner consistent with an essential function for ME3 in ME2-null cancer cells. Mechanistically, integrated metabolomic and molecular investigation of cells deficient in mitochondrial malic enzymes revealed diminished NADPH production and consequent high levels of reactive oxygen species. These changes activate AMP activated protein kinase (AMPK), which in turn directly suppresses sterol regulatory element-binding protein 1 (SREBP1)-directed transcription of its direct targets including the BCAT2 branched-chain amino acid transaminase 2) gene. BCAT2 catalyses the transfer of the amino group from branched-chain amino acids to α-ketoglutarate (α-KG) thereby regenerating glutamate, which functions in part to support de novo nucleotide synthesis. Thus, mitochondrial malic enzyme deficiency, which results in impaired NADPH production, provides a prime 'collateral lethality' therapeutic strategy for the treatment of a substantial fraction of patients diagnosed with this intractable disease.

It is important to adequately and timely identify individuals with cancer worries amongst participants in a pancreatic ductal adenocarcinoma (PDAC) surveillance program, because they could benefit from psychosocial support to decrease distress. Therefore, the aim of this study was to assess both psychosocial and clinical factors associated with cancer worries. High-risk individuals participating in PDAC-surveillance were invited to annually complete a cancer worry scale (CWS) questionnaire which was sent after counseling by the clinical geneticist (T0), after intake for participation in PDAC-surveillance (T1), and then annually after every MRI and endoscopic ultrasonography (EUS) (T2 and further). Analyses were performed to identify factors associated with cancer worries in the second year of surveillance (T3). We found a significant intra-individual decrease in cancer worries (β = -0.84, P < 0.001), nevertheless, 33 % of individuals had a CWS-score ≥14 at T3. We found one factor significantly associated with cancer worries at T3: having a family member affected by PDAC <50 years of age (β = 0.22, P = 0.03). The detection of a cystic lesion, a shortened surveillance interval, or undergoing pancreatic surgery did not lead to more cancer worries (P = 0.163, P = 0.33, and P = 0.53, respectively). In conclusion, this study identified 'a family history of PDAC <50 years of age' as the only predictor of cancer worries experienced after 2 years of surveillance in individuals at high risk of developing PDAC. This knowledge could help clinicians to timely identify individuals 'at risk' for high levels of cancer worries who would likely benefit from psychosocial support., Competing Interests: The authors declare that they have no conflict of interest. Ethical approval All procedures performed in studies involving human participants were in accordance with the ethical standards of the institutional and/or national research committee and with the 1964 Helsinki declaration and its later amendments or comparable ethical standards. Informed consent Informed consent was obtained from all individual participants included in the study. Research involving human participants The Ethical Committee of all participating centers approved the study protocol and the study was conducted in accordance with the Declaration of Helsinki. All participants gave written informed consent prior to the performance of any study-related investigations.

Background: Uncertainties remain over whether prophylactic surgery or surveillance is the better management option for intraductal papillary mucinous neoplasm of the pancreas. The aim of this preliminary study was to determine if differences in anxiety and quality of life exist between patients who have surgery or undergo surveillance., Methods: Recruited patients were given the Hospital Anxiety and Depression Scale, a general survey that evaluates anxiety, and the Functional Assessment of Cancer Therapy-Pancreas, a disease-specific survey that assesses quality of life. Questionnaires were scored by standardized algorithms and compared using Student's t test or Wilcoxon rank-sum test., Results: Sixteen patients had surgery and 16 patients were undergoing surveillance. Mean age was 66.8 ± 19.9 years. Responses from both groups were remarkably similar. Surgery patients scored higher on the anxiety questionnaire than surveillance patients, although not statistically significant (p = 0.09). Surgery patients scored lower on the functional well-being domain of the quality-of-life instrument (p = 0.03), though there were no differences in overall quality of life., Conclusion: Prophylactic surgery does not reduce quality of life, and a protocol of surveillance does not appear to generate undue anxiety in this select patient group. Further investigation with more patients is required to validate these findings.

The European Study Group for Pancreatic Cancer (ESPAC-1) study is the largest study of adjuvant treatment for pancreatic ductal adenocarcinoma to date and confirmed a survival advantage for adjuvant chemotherapy but not for chemoradiation. The importance of parallel evaluation of survival and quality of life (QoL) has been recognized as fundamental and the aim was to assess QoL and quality adjusted survival. A longitudinal QoL study on a subset of ESPAC-1 patients who prospectively completed the EORTC QLQ C-30 questionnaire during treatment and follow-up. An integrated quality-survival product method was used to adjust any treatment effect on survival by a function of measured QoL, calculated over a restricted 24-month-period (QALM-24). Three hundred and sixteen patients completed 1,201 questionnaires. There were no differences between treatment groups in dimension scores at baseline (randomization). For the chemotherapy group, the mean Quality Adjusted Life Months over 24 months (QALM-24) was 9.6 (95% CI: 8.7, 11.2) months compared with the mean QALM-24 of 8.6 (95% CI: 7.6, 10.5) months for the no chemotherapy group. For the chemoradiation group, the mean QALM-24 was 7.1 (95% CI: 6.0, 9.0) months compared with the mean QALM-24 of 8.1 (95% CI: 7.0, 10.0) months for the no chemoradiation group. The previously reported survival advantage supporting the use of adjuvant chemotherapy is maintained when adjusted using quality adjusted survival methodology. Chemotherapy provided on average an additional 1.0 quality-adjusted life months within a restricted 2-year time period from the time of resection., (Copyright 2008 UICC.)
