Quality-of-life outcomes for adjuvant chemotherapy in early-stage non-small-cell lung cancer: results from a randomized trial, JBR.10

Patient-Reported Outcomes of Postoperative NSCLC Patients with or without Staged Chinese Herb Medicine Therapy during Adjuvant Chemotherapy (NALLC 2): A Randomized, Double-Blind, Placebo-Controlled Trial

OBJECTIVE

To investigate whether the combination of chemotherapy with staged Chinese herbal medicine (CHM) therapy could enhance health-related quality of life (QoL) in non-small-cell lung cancer (NSCLC) patients and prolong the time before deterioration of lung cancer symptoms, in comparison to chemotherapy alone.

METHODS

A prospective, double-blind, randomized, controlled trial was conducted from December 14, 2017 to August 28, 2020. A total of 180 patients with stage I B-IIIA NSCLC from 5 hospitals in Shanghai were randomly divided into chemotherapy combined with CHM (chemo+CHM) group (120 cases) or chemotherapy combined with placebo (chemo+placebo) group (60 cases) using stratified blocking randomization. The European Organization for Research and Treatment of Cancer (EORTC) Quality-of-Life-Core 30 Scale (QLQ-C30) was used to evaluate the patient-reported outcomes (PROs) during postoperative adjuvant chemotherapy in patients with early-stage NSCLC. Adverse events (AEs) were assessed in the safety analysis.

RESULTS

Out of the total 180 patients, 173 patients (116 in the chemo+CHM group and 57 in the chemo+placebo group) were included in the PRO analyses. The initial mean QLQ-C30 Global Health Status (GHS)/QoL scores at baseline were 57.16 ± 1.64 and 57.67 ± 2.25 for the two respective groups (P>0.05). Compared with baseline, the chemo+CHM group had an improvement in EORTC QLQ-C30 GHS/QoL score at week 18 [least squares mean (LSM) change 17.83, 95% confidence interval (CI) 14.29 to 21.38]. Conversely, the chemo+placebo group had a decrease in the score (LSM change -13.67, 95% CI -22.70 to -4.63). A significant between-group difference in the LSM GHS/QoL score was observed, amounting to 31.63 points (95% CI 25.61 to 37.64, P<0.001). The similar trends were observed in physical functioning, fatigue and appetite loss. At week 18, patients in the chemo+CHM group had a higher proportion of improvement or stabilization in GHS/QoL functional and symptom scores compared to chemo+placebo group (P<0.001). The median time to deterioration was longer in the chemo+CHM group for GHS/QoL score [hazard ratio (HR)=0.33, 95% CI 0.23 to 0.48, P<0.0010], physical functioning (HR=0.43, 95% CI 0.25 to 0.75, P=0.0005), fatigue (HR=0.47, 95% CI 0.30 to 0.72, P<0.0001) and appetite loss (HR=0.65, 95% CI 0.42 to 1.00, P=0.0215). The incidence of AEs was lower in the chemo+CHM group than in the chemo+placebo group (9.83% vs. 15.79%, P=0.52).

CONCLUSION

The staged CHM therapy could help improve the PROs of postoperative patients with early-stage NSCLC during adjuvant chemotherapy, which is worthy of further clinical research. (Registry No. NCT03372694).

The Role of Adjuvant Chemotherapy before Osimertinib in Epidermal Growth Factor Receptor Mutant Resected Non-Small Cell Lung Cancer and Communicating It to Patients

Patients with radically resected stage II and III NSCLC are exposed to a high risk of disease recurrence. Thus, adjuvant cisplatin-based chemotherapy is routinely offered to this patient population, although it results in an absolute increase in 5-year survival rate of only 4%. This modest improvement in survival rate makes it challenging to communicate to our patients about the decision to be treated with adjuvant chemotherapy or not. Nowadays, the decision to administer adjuvant chemotherapy or not in resected NSCLC is almost never completely shared with patients because its role is very difficult to explain. The risk-benefit ratio becomes clearly unfavourable in elderly and unfit patients. Recently, the phase III ADAURA trial demonstrated a clinically significant disease-free survival and overall survival benefit with adjuvant osimertinib (with or without adjuvant chemotherapy) versus a placebo in EGFR-mutated stage IB-IIIA resected NSCLC. In this patient population, the decision to administer chemotherapy or not is much more challenging given the great benefit offered by osimertinib alone. Thus, it is time now to improve our communication tools to explain the role of adjuvant chemotherapy to our patients, especially in the EGFR-mutated population, in order to undertake real shared decision making in a clinical context in which the opportunity to administer toxic chemotherapy is debatable and subjective.

Pain management for post-treatment survivors of complex cancers: a qualitative study of opioids and cannabis

Aim: We aimed to understand experiences with opioids and cannabis for post-treatment cancer survivors. Patients & methods: We conducted seven focus groups among head and neck and lung cancer survivors, using standard qualitative methodology to explore themes around 1) post-treatment pain and 2) utilization, perceived benefits and perceived harms of cannabis and opioids. Results & conclusion: Survivors (N = 25) experienced addiction fears, stigma and access challenges for both products. Opioids were often perceived as critical for severe pain. Cannabis reduced pain and anxiety for many survivors, suggesting that anxiety screening, as recommended in guidelines, would improve traditional pain assessment. Opioids and cannabis present complex harms and benefits for post-treatment survivors who must balance pain management and minimizing side effects.

Understanding health-related quality of life measures used in early-stage non-small cell lung cancer clinical trials: A review

Health-related quality of life (HRQoL) is an important consideration in cancer clinical research, which can be substantially influenced by cancer treatment procedures and medications. The treatment landscape for early-stage (stage I-III) non-small cell lung cancer (NSCLC) is rapidly evolving. In this light, it is important to evaluate the most suitable instruments for HRQoL assessment and timing. Given there is often a requirement for patients with early-stage disease to receive long-term treatment to reduce the risk of disease recurrence after surgery, maintenance or improvement in HRQoL is an important goal of both neoadjuvant and adjuvant treatments. Key challenges with assessing HRQoL relate to the suitability of existing instruments to measure relevant treatment-related adverse effects, consistency in HRQoL assessment approach between similar studies, gaps in data collection and reporting, and interpretation of longitudinal data. Frequent assessments during and after treatment are warranted to capture the true impact of treatment and disease progression on HRQoL, and changes in the relative importance of these factors over time. There is scope for improving existing HRQoL approaches, including ease of use and integration of digital tools to facilitate analysis and interpretation, to enhance the experience of both patients and healthcare professionals. In this narrative review, we discuss key considerations for HRQoL assessment and evaluate the tools currently available to measure HRQoL in NSCLC, many of which were designed with advanced disease in mind. We focus on the key challenges of measuring HRQoL for the specific needs of patients with early-stage disease, and consider future perspectives, to determine the most appropriate HRQoL instruments and analysis methods to use in early-stage NSCLC clinical trials.1.

Cost-effectiveness of granulocyte colony-stimulating factors (G-CSFs) for the prevention of febrile neutropenia (FN) in patients with cancer

PURPOSE

Clinical practice guidelines recommend the use of all approved granulocyte colony-stimulating factors (G-CSFs), including filgrastim and pegfilgrastim, as primary febrile neutropenia (FN) prophylaxis in patients receiving high- or intermediate-risk regimens (in those with additional patient risk factors). Previous studies have examined G-CSF cost-effectiveness by cancer type in patients with a high baseline risk of FN. This study evaluated patients with breast cancer (BC), non-small cell lung cancer (NSCLC), or non-Hodgkin's lymphoma (NHL) receiving therapy who were at intermediate risk for FN and compared primary prophylaxis (PP) and secondary prophylaxis (SP) using biosimilar filgrastim or biosimilar pegfilgrastim in Austria, France, and Germany.

METHODS

A Markov cycle tree-based model was constructed to evaluate PP versus SP in patients with BC, NSCLC, or NHL receiving therapy over a lifetime horizon. Cost-effectiveness was evaluated over a range of willingness-to-pay (WTP) thresholds for incremental cost per quality-adjusted life year (QALY) gained. Sensitivity analyses evaluated uncertainty.

RESULTS

Results demonstrated that using biosimilar filgrastim as PP compared to SP resulted in incremental cost-effectiveness ratios (ICERs) well below the most commonly accepted WTP threshold of €30,000. Across all three countries, PP in NSCLC had the lowest cost per QALY, and in France, PP was both cheaper and more effective than SP. Similar results were found using biosimilar pegfilgrastim, with ICERs generally higher than those for filgrastim.

CONCLUSIONS

Biosimilar filgrastim and pegfilgrastim as primary prophylaxis are cost-effective approaches to avoid FN events in patients with BC, NSCLC, or NHL at intermediate risk for FN in Austria, France, and Germany.

Premature senescence and cardiovascular disease following cancer treatments: mechanistic insights

Cardiovascular disease (CVD) is a leading cause of morbidity and mortality, especially among the aging population. The "response-to-injury" model proposed by Dr. Russell Ross in 1999 emphasizes inflammation as a critical factor in atherosclerosis development, with atherosclerotic plaques forming due to endothelial cell (EC) injury, followed by myeloid cell adhesion and invasion into the blood vessel walls. Recent evidence indicates that cancer and its treatments can lead to long-term complications, including CVD. Cellular senescence, a hallmark of aging, is implicated in CVD pathogenesis, particularly in cancer survivors. However, the precise mechanisms linking premature senescence to CVD in cancer survivors remain poorly understood. This article aims to provide mechanistic insights into this association and propose future directions to better comprehend this complex interplay.

Health State Utility Values in Early-Stage Non-small Cell Lung Cancer: A Systematic Literature Review

BACKGROUND

Non-small cell lung cancer (NSCLC) is the predominant histological subtype of lung cancer and is the leading cause of cancer-related deaths globally. Quality of life is an important consideration for patients and current treatments can adversely affect health-related quality of life (HRQoL).

OBJECTIVE

The objectives of this systematic literature review (SLR) were to identify and provide a comprehensive catalogue of published health state utility values (HSUVs) in patients with early-stage NSCLC and to understand the factors impacting on HSUVs in this indication.

METHODS

Electronic searches of Embase, MEDLINE and Evidence-Based Medicine Reviews were conducted via the Ovid platform in March 2021 and June 2022 and were supplemented by grey literature searches of conference proceedings, reference lists, health technology assessment bodies, and other relevant sources. Eligibility criteria were based on patients with early-stage (stage I-III) resectable NSCLC receiving treatment in the adjuvant or neoadjuvant setting. No restriction was placed on interventions or comparators, geography, or publication date. English language publications or non-English language publications with an English abstract were of primary interest. A validated checklist was applied to conduct quality assessment of the full publications.

RESULTS

Twenty-nine publications (27 full publications and two conference abstracts) met all eligibility criteria and reported 217 HSUVs and seven disutilities associated with patients with early NSCLC. The data showed that increasing disease stage is associated with decreasing HRQoL. It was also indicated that utility values vary by treatment approach; however, the choice of treatment may be influenced by the patients' disease stage at presentation. Few studies aligned with the requirements of health technology assessment (HTA) bodies, indicating a need for future studies to conform to these preferences, making them suitable for use in economic evaluations.

CONCLUSIONS

This SLR found that disease stage and treatment approach were two of several factors that can impact patient-reported HRQoL. Additional studies are warranted to confirm these findings and to investigate emerging therapies for early NSCLC. In collecting a catalogue of HSUV data, this SLR has begun to identify the challenges associated with identifying reliable utility value estimates suitable for use in economic evaluations of early NSCLC.

Anxiety, depression, and quality of life in postoperative non-small cell lung cancer patients under the intervention of cognitive-behavioral stress management

Objective

Cognitive-behavioral stress management (CBSM) is a psychotherapy that helps patients cognize and manage stress to improve mental health and quality of life. This study aimed to explore the influence of CBSM on anxiety, depression, and quality of life in non-small cell lung cancer (NSCLC) patients.

Methods

In total, 172 NSCLC patients who received tumor resection were randomized 1:1 into the usual care (UC) group (N = 86) and CBSM group (N = 86) to receive 10-week UC and CBSM interventions. Moreover, all participants attended a 6-month follow-up.

Results

Hospital Anxiety and Depression Scales (HADS)-anxiety score at 3^rd month (M3) (P = 0.015) and 6^th month (M6) (P = 0.018), HADS-depression score at M3 (P = 0.040) and M6 (P = 0.028), and depression rate at M6 (P = 0.035) were descended in CBSM group compared to UC group. Besides, depression severity was reduced at M6 (P = 0.041) in CBSM group compared to UC group, but anxiety severity only showed a decreased trend (P = 0.051). Additionally, Quality of Life Questionnaire-Core 30 (QLQ-C30) global health status score and QLQ-C30 function score at 1^st month (M1), M3, and M6 were elevated (all P < 0.05), while QLQ-C30 symptoms score was declined at M1 (P = 0.031) and M3 (P = 0.014) in CBSM group compared to UC group. Notably, the efficacy of CBSM was impressive in patients with baseline depression or undergoing adjuvant therapy.

Conclusion

CBSM is a feasible intervention that effectively improves mental health and quality of life in postoperative NSCLC patients.

Audiologists' perceived value of ototoxicity management and barriers to implementation for at-risk cancer patients in VA: the OtoMIC survey

PURPOSE

Platinum-based chemotherapies used to treat many types of cancers are ototoxic. Ototoxicity management (OtoM) to mitigate the ototoxic outcomes of cancer survivors is recommended practice yet it is not a standard part of oncologic care. Although more than 10,000 patients each year are treated with platinum-based chemotherapies at the US Veterans Health Administration (VA), the current state of OtoM in VA is not well-defined. This study reports on a national survey of VA audiologists' perceptions regarding OtoM in cancer patients.

METHODS

A 26-item online survey was administered to VA audiologists and service chiefs across the VA's 18 regional systems of care. Descriptive statistics and deductive thematic analysis were used to analyze the data.

RESULTS

The 61 respondents included at least one from each VA region. All reported they felt some form of OtoM was necessary for at-risk cancer patients. A pre-treatment baseline, the ability to detect ototoxicity early, and management of ototoxic effects both during and after treatment were considered high value objectives of OtoM by respondents. Roughly half reported routinely providing these services for patients receiving cisplatin and carboplatin. Respondents disagreed regarding appropriate hearing testing schedules and how to co-manage OtoM responsibilities with oncology. They identified barriers to care that conformed to three themes: care and referral coordination with oncology, audiology workload, and lack of protocols.

CONCLUSIONS

Although VA audiologists value providing OtoM for cancer patients, only about half perform OtoM for highly ototoxic treatment regimens. The OtoMIC survey provides clinician perspectives to benchmark and address OtoM care gaps.

IMPLICATIONS FOR CANCER SURVIVORS

Collaboration between oncology and audiology is needed to improve current OtoM processes, so that cancer survivors can have more control over their long term hearing health.

Health-Related Quality of Life Outcomes in Patients with Resected Epidermal Growth Factor Receptor-Mutated Non-Small Cell Lung Cancer Who Received Adjuvant Osimertinib in the Phase III ADAURA Trial

PURPOSE

In the phase III ADAURA trial, adjuvant treatment with osimertinib versus placebo, with/without prior adjuvant chemotherapy, resulted in a statistically significant and clinically meaningful disease-free survival benefit in completely resected stage IB-IIIA EGFR-mutated (EGFRm) non-small cell lung cancer (NSCLC). We report health-related quality of life (HRQoL) outcomes from ADAURA.

PATIENTS AND METHODS

Patients randomized 1:1 received oral osimertinib 80 mg or placebo for 3 years or until recurrence/discontinuation. HRQoL (secondary endpoint) was measured using the Short Form-36 (SF-36) health survey at baseline, 12, and 24 weeks, then every 24 weeks until recurrence or treatment completion/discontinuation. Exploratory analyses of SF-36 score changes from baseline until week 96 and time to deterioration (TTD) were performed in the overall population (stage IB-IIIA; N = 682). Clinically meaningful changes were defined using the SF-36 manual.

RESULTS

Baseline physical/mental component summary (PCS/MCS) scores were comparable between osimertinib and placebo (range, 46-47) and maintained to Week 96, with no clinically meaningful differences between arms; difference in adjusted least squares (LS) mean [95% confidence intervals (CI), -1.18 (-2.02 to -0.34) and -1.34 (-2.40 to -0.28), for PCS and MCS, respectively. There were no differences between arms for TTD of PCS and MCS; HR, 1.17 (95% CI, 0.82-1.67) and HR, 0.98 (95% CI, 0.70-1.39), respectively.

CONCLUSIONS

HRQoL was maintained with adjuvant osimertinib in patients with stage IB-IIIA EGFRm NSCLC, who were disease-free after complete resection, with no clinically meaningful differences versus placebo, further supporting adjuvant osimertinib as a new treatment in this setting. See related commentary by Patil and Bunn, p. 2204.

Deconstructing ADAURA. It is Not Yet Time to Forgo Platinum-based Adjuvant Chemotherapy in Resected Early Stage (IB-IIIA) EGFR-mutant NSCLC

Recently, the ADAURA study demonstrated statistically significant improved disease-free survival (DFS) with adjuvant osimertinib in patients with resected stage IB-IIIA non-small cell lung cancer (NSCLC) harboring an epidermal growth factor receptor (EGFR) mutation. A consistent improvement in disease-free survival (DFS) was shown, regardless of whether or not patients received adjuvant chemotherapy. Given benefit seen with and without adjuvant chemotherapy, some clinicians may be tempted to forgo chemotherapy and only offer osimertinib post surgical resection. Would this approach be appropriate? Here we carefully dissect data from the ADAURA trial and review how this may fit into the existing evidence on the treatment of early stage NSCLC by discussing five themes, the study design of ADAURA, attempts on adjuvant tyrosine kinase inhibitors, prior studies to support adjuvant chemotherapy, how adjuvant chemotherapy was administered in ADAURA and consideration of toxicities.

A Randomized Controlled Trial Using Automated Technology for Improving Ototoxicity Monitoring in VA Oncology Patients

Purpose Determine the efficacy of ototoxicity monitoring (OM) administered as automated protocols with the Oto-ID mobile audiometer (automated ototoxicity monitoring [A-OM]), compared with usual care (UC) OM in cancer patients receiving cisplatin. Method Participants were patients (n = 46, mean age 64.7 years; range: 30-78 years) receiving cisplatin-based chemotherapy at the Department of Veterans Affairs Portland Health Care System. A randomized controlled trial contrasted A-OM and UC at up to three program evaluations (PEs) conducted by the study audiologist who was blinded to arm through PE1. PE1 occurred before randomization or oncology treatment; PE2 and PE3 occurred during and/or after treatment at 35 and 365 days postrandomization. The A-OM group (n = 24) used Oto-ID to screen their hearing before each cisplatin dose. Oto-ID results were sent to the study audiologist for interpretation, follow-up, and care coordination. The UC group (n = 22) received a consult for OM services through the audiology clinic. Outcomes included hearing shift near each patient's high-frequency hearing limit, revised hearing-handicap inventory score, and survival time from the start of treatment. Adherence to OM protocols, patients' use of aural rehabilitation services, and oncologists' treatment decisions were also examined. Results Ototoxicity was identified at a high overall rate (46% and 76% at 35 and 365 days, respectively, postrandomization). Adherence to monitoring prior to each cisplatin dose was 83.3% for those randomized to A-OM compared with 4.5% for UC. Randomization to A-OM was not associated with reduced ototoxic hearing shifts or self-reported hearing handicap relative to UC; neither did it compromise participants' survival. Half of participants in each arm accessed aural rehabilitation services. One in each arm had a documented ototoxicity-related cisplatin dose reduction. Conclusions Auditory impairment was an actionable concern for the participants and their oncology providers. A dedicated surveillance program using the Oto-ID's automated protocols improved adherence to OM recommendations over a traditional UC service delivery model.

Primary Prophylaxis With Biosimilar Filgrastim for Patients at Intermediate Risk for Febrile Neutropenia: A Cost-Effectiveness Analysis

PURPOSE

Temporary COVID-19 guideline recommendations have recently been issued to expand the use of colony-stimulating factors in patients with cancer with intermediate to high risk for febrile neutropenia (FN). We evaluated the cost-effectiveness of primary prophylaxis (PP) with biosimilar filgrastim-sndz in patients with intermediate risk of FN compared with secondary prophylaxis (SP) over three different cancer types.

METHODS

A Markov decision analytic model was constructed from the US payer perspective over a lifetime horizon to evaluate PP versus SP in patients with breast cancer, non-small-cell lung cancer (NSCLC), and non-Hodgkin lymphoma (NHL). Cost-effectiveness was evaluated over a range of willingness-to-pay thresholds for incremental cost per FN avoided, life year gained, and quality-adjusted life year (QALY) gained. Sensitivity analyses evaluated uncertainty.

RESULTS

Compared with SP, PP provided an additional 0.102-0.144 LYs and 0.065-0.130 QALYs. The incremental cost-effectiveness ranged from $5,660 in US dollars (USD) to $20,806 USD per FN event avoided, $5,123 to $31,077 USD per life year gained, and $7,213 to $35,563 USD per QALY gained. Over 1,000 iterations, there were 73.6%, 99.4%, and 91.8% probabilities that PP was cost-effective at a willingness to pay of $50,000 USD per QALY gained for breast cancer, NSCLC, and NHL, respectively.

CONCLUSION

PP with a biosimilar filgrastim (specifically filgrastim-sndz) is cost-effective in patients with intermediate risk for FN receiving curative chemotherapy regimens for breast cancer, NSCLC, and NHL. Expanding the use of colony-stimulating factors for patients may be valuable in reducing unnecessary health care visits for patients with cancer at risk of complications because of COVID-19 and should be considered for the indefinite future.

Integration of immunotherapy into adjuvant therapy for resected non-small-cell lung cancer: ALCHEMIST chemo-IO (ACCIO)

Non-small-cell lung cancer (NSCLC) causes significant mortality each year. After successful resection of disease stage IB (>4 cm) to IIIA (per AJCC 7), adjuvant platinum-based chemotherapy improves median overall survival and is the standard of care, but many patients still experience recurrence of disease. An adjuvant regimen with greater efficacy could substantially improve outcomes. Pembrolizumab, a programmed cell death-1 inhibitor, has become an important option in the treatment of metastatic NSCLC. ALCHEMIST is a clinical trial platform of the National Cancer Institute that includes biomarker analysis for resected NSCLC and supports therapeutic trials including A081801 (ACCIO), a three-arm study that will evaluate both concurrent chemotherapy plus pembrolizumab and sequential chemotherapy followed by pembrolizumab to standard of care adjuvant platinum-based chemotherapy.

Clinical trial registration: NCT04267848 (ClinicalTrials.gov)

Non-small-cell lung cancer adjuvant platinum-based therapy is standard of care (SOC). Including pembrolizumab may improve efficacy. A081801 (ACCIO) is a three-arm study: SOC versus sequential chemotherapy–pembrolizumab versus concurrent chemotherapy + pembrolizumab.

Neoadjuvant and adjuvant end-points in health technology assessment in oncology

Health technology assessment (HTA) of clinical and economic value of a new intervention is an integral step in providing the access of patients to innovative cancer care and treatment. Overall survival (OS) is the preferred criterion for demonstrating the therapeutic efficacy in HTA given its direct clinical and patient relevance. However, with often long life expectancy of patients with early cancer, analysis of OS becomes less practical. Partially due to this reason, pathological complete response (pCR) and time-to-event end-points like disease-free survival are frequently incorporated into the pivotal clinical trials in the neoadjuvant and adjuvant settings. However, there exists a discrepancy between different national HTA bodies regarding the acknowledgement of patient relevance of these end-points. In this article, we analysed the perspectives of patients on different aspects of end-points used in clinical trials in early cancer. Gathered evidence strongly suggests that complete tumour eradication and reduced risk of recurrence provide important psychological benefits thus signifying that pCR and time-to-event end-points are directly relevant to patients. Additionally, we reviewed opinions on patient relevance of neoadjuvant and adjuvant therapy end-points adopted by HTA bodies during the recent evaluations. We found that improvements in end-points used in the adjuvant setting were commonly considered as valuable to patients. In contrast, opinions on patient relevance of neoadjuvant therapy end-points varied between the national HTA bodies. Universal acknowledgement of patient relevance of therapeutic end-points for early cancer by HTA bodies is necessary to balance the inequality in uptake of innovative therapies into national healthcare systems.

Survival benefit and toxicity profile of adjuvant icotinib for patients with EGFR mutation-positive non-small cell lung carcinoma: a retrospective study

Background

Adjuvant epidermal growth factor receptor (EGFR) tyrosine kinase inhibitors (TKIs) are increasing considered for the tailored management of resectable non-small cell lung cancer (NSCLC). This study aimed to analyze the survival and toxicity profile of patients with EGFR mutation-positive NSCLC treated with adjuvant icotinib.

Methods

This was a single-center retrospective study of patients with EGFR mutation-positive NSCLC who underwent R0 (microscopically margin-negative) resection and received adjuvant icotinib between November 2011 and December 2017. The outcomes included 2-year disease-free survival (DFS) rate, 3-year overall survival (OS) rates, DFS, OS, and adverse events (AEs).

Results

A total of 86 patients receiving adjuvant icotinib were included. Their mean age was 59.7±10.0 years, and 26 (30.2%) patients were male. The 2-year DFS rate was 86.7%, and the 3-year OS rate was 95.3% with adjuvant icotinib. DFS (P=0.044) and OS (P=0.003) are better in stage I/II disease than in stage III disease. There seems no differences in DFS and OS between patients with low or high preoperative CEA levels (cutoff of 5 ng/mL), patients with exon 19 or 21 EGFR mutation or patients with or without smoking history. The most common AEs with adjuvant icotinib were rash (83.7%) and diarrhea (19.8%). One (1.2%) patient-reported grade ≥3 AEs. No treatment-related death occurred.

Conclusions

For patients with EGFR mutation-positive NSCLC, adjuvant icotinib might be associated with a promising survival benefit, with an acceptable toxicity profile.

Magnetic particle targeting for diagnosis and therapy of lung cancers

Over the past decade, the growing interest in targeted lung cancer therapy has guided researchers toward the cutting edge of controlled drug delivery, particularly magnetic particle targeting. Targeting of tissues by magnetic particles has tackled several limitations of traditional drug delivery methods for both cancer detection (e.g., using magnetic resonance imaging) and therapy. Delivery of magnetic particles offers the key advantage of high efficiency in the local deposition of drugs in the target tissue with the least harmful effect on other healthy tissues. This review first overviews clinical aspects of lung morphology and pathogenesis as well as clinical features of lung cancer. It is followed by reviewing the advances in using magnetic particles for diagnosis and therapy of lung cancers: (i) a combination of magnetic particle targeting with MRI imaging for diagnosis and screening of lung cancers, (ii) magnetic drug targeting (MDT) through either intravenous injection and pulmonary delivery for lung cancer therapy, and (iii) computational simulations that models new and effective approaches for magnetic particle drug delivery to the lung, all supporting improved lung cancer treatment. The review further discusses future opportunities to improve the clinical performance of MDT for diagnosis and treatment of lung cancer and highlights clinical therapy application of the MDT as a new horizon to cure with minimal side effects a wide variety of lung diseases and possibly other acute respiratory syndromes (COVID-19, MERS, and SARS).

Quality of life with adjuvant gefitinib versus vinorelbine plus cisplatin in patients with completely resected stage II-IIIA (N1-N2) EGFR-mutant non-small-cell lung cancer: Results from the ADJUVANT (CTONG1104) study

OBJECTIVES

Health-related quality of life (HRQoL) data complement conventional clinical endpoints when comparing adjuvant gefitinib with chemotherapy in patients with early-stage non-small-cell lung cancer (NSCLC) and epidermal growth factor receptor (EGFR) mutations. This study aimed to assess changes in HRQoL with adjuvant gefitinib vs chemotherapy in this patient group.

MATERIALS AND METHODS

In the phase III ADJUVANT trial, patients with completely resected, stage II-IIIA (N1-N2), EGFR-mutant NSCLC were randomized (1:1) to receive either gefitinib for 24 months or vinorelbine plus cisplatin (VP) every 3 weeks for four cycles. HRQoL was assessed as a secondary endpoint using the Functional Assessment of Cancer Therapy-Lung Cancer (FACT-L), Lung Cancer Symptom Scale (LCSS) questionnaires, and Trial Outcome Index (TOI) composite score. HRQoL dynamics, improvements, and time to deterioration were compared between groups.

RESULTS

At baseline, 104 of 106, and 80 of 87 patients receiving gefitinib and VP, respectively, completed two questionnaires (FACT-L and LCSS). Baseline scores were balanced between groups. Although HRQoL fluctuated and gradually improved in both groups, longitudinally higher scores were reported with gefitinib than VP (FACT-L, odds ratio 418.16, 95 % confidence interval [CI] 2.75-63509.05, p =  0.019; LCSS, 1.13, 1.04-1.22, p =  0.003; TOI, 88.39, 4.40-1775.05, p =  0.003). Time to deterioration in HRQoL was delayed with gefitinib compared with VP (FACT-L, median 69 vs 6 weeks, hazard ratio 0.62, 95 % CI 0.42-0.90, p =  0.013; LCSS, median 45 vs 6 weeks, 0.63, 0.43-0.93, p =  0.020; TOI, median 164 vs 9 weeks, 0.51, 0.33-0.77, p =  0.001).

CONCLUSION

Adjuvant gefitinib is associated with improved HRQoL over VP, supporting its use in patients with stage II-IIIA (N1-N2), EGFR-mutant NSCLC.

Effects of curative-intent lung cancer therapy on functional exercise capacity and patient-reported outcomes

PURPOSE

Lung cancer treatment can lead to negative health consequences. We analyzed the effects of curative-intent lung cancer treatment on functional exercise capacity (EC) and patient-reported outcomes (PROs).

METHODS

We performed a prospective, observational cohort study of consecutive patients with stage I-IIIA lung cancer undergoing curative-intent therapy and assessed functional EC (primary outcome, six-minute walk distance (6MWD)), cancer-specific quality of life (QoL) (secondary outcome, European Organization for Research and Treatment of Cancer QoL Questionnaire Core 30 (EORTC-QLQ-C30) summary score), and exploratory outcomes including dyspnea (University of California San Diego Shortness of Breath Questionnaire (UCSD SOBQ)) and fatigue Brief Fatigue Inventory (BFI)) symptoms before and at 1 to 3 months post-treatment. We analyzed the time effect of treatment on outcomes using multivariable generalized estimating equations.

RESULTS

In 35 enrolled participants, treatment was associated with a clinically meaningful and borderline-significant decline in functional EC ((mean change, 95% CI) 6MWD = - 25.4 m (- 55.3, + 4.47), p = 0.10), clinically meaningful and statistically significant higher dyspnea (UCSD SOBQ = + 13.1 (+ 5.7, + 20.6), p = 0.001) and fatigue (BFI = + 10.0 (+ 2.9, + 17.0), p = 0.006), but no clinically meaningful or statistically significant change in cancer-specific QoL (EORTC-QLQ-C30 summary score = - 3.4 (- 9.8, + 3.0), p = 0.30).

CONCLUSIONS

Among the first prospective analysis of the effect of curative-intent lung cancer treatment on functional EC and PROs, we observed worsening dyspnea and fatigue, and possibly a decline in functional EC but not cancer-specific QoL at 1 to 3 months post-treatment. Interventions to reduce treatment-related morbidities and improve lung cancer survivorship may need to focus on reducing dyspnea, fatigue, and/or improving functional EC.

The effect of comprehensive rehabilitation program plus chemotherapy on quality of life in patients with postoperative non-small-cell lung cancer: study protocol of a multicenter randomized clinical trial

Background

Comprehensive rehabilitation therapy based on traditional Chinese medicine (TCM) has been widely applied in various cancer treatments in China. Thus far, Chinese herbal medicine (CHM) has been shown effective in reducing the adverse effects of chemotherapy and improving the quality of life (QoL) during chemotherapy. The purpose of the present study is to compare the effects of CHM plus Liu Zi Jue (LZJ) exercises with CHM plus rehabilitation education and with placebo plus rehabilitation education in patients who have undergone complete resection for nonsmall-cell lung cancer (NSCLC) followed by postoperative adjuvant chemotherapy.

Methods and design

A multicenter, randomized clinical trial will be performed with 354 stage Ib–IIIa NSCLC patients in five centers in China. Patients satisfying the inclusion criteria will be randomly divided into three groups according to a 1:1:1 ratio: intervention group A (IGA), intervention group B (IGB), and control group (CG). Each group will receive adjuvant platinum-based doublet chemotherapy for a total of four cycles. IGA participants will receive chemotherapy combined with CHM and LZJ exercises, IGB participants will receive chemotherapy combined with CHM and rehabilitation education, and CG participants will receive chemotherapy combined with placebo and rehabilitation education. The herbal treatment patients will be given granules daily and LZJ exercises will be performed four times per week during chemotherapy. The primary outcome is QoL, which will be assessed with the European Organization for Research and Treatment of Cancer (EORTC)-QLQ-C43 scale in each cycle. The secondary outcomes include the 2-year disease-free survival rate, disease-free survival, TCM symptoms, tumor markers, safety, and adverse events. After treatment, the patients will be followed up every 3 months within 2 years and every 6 months after 2 years until disease recurrence and/or metastasis.

Discussion

Our previous study reported that CHM in combination with chemotherapy could lower the overall incidence of adverse events but increased digestive and gastrointestinal side effects compared with chemotherapy alone in postoperative NSCLC patients. This study will lay a foundation for the effectiveness of chemotherapy with or without a comprehensive rehabilitation program for QoL in patients with postoperative NSCLC.

Cancer survivors treated with platinum-based chemotherapy affected by ototoxicity and the impact on quality of life: a narrative synthesis systematic review

Objective: To identify any change in quality of life (QoL) caused by chemotherapy-induced toxicities, such as hearing loss and tinnitus, to provide information in order to improve services and aid clinicians in their decision-making. Design: This systematic review followed the preferred reporting items for systematic reviews and meta-analysis (PRISMA) checklist. The search terms were cancer, platinum-based chemotherapy, ototoxicity and "quality of life". Titles and abstracts, followed by full texts, were screened by two independent researchers. The relevant data were extracted and quality analysis was performed using the NIH Quality Assessment Tool. Study sample: About 308 titles and abstracts were screened, and 27 full-text articles were screened. Ten articles representing 11 studies were included in the review. Study design included cross-sectional studies, randomised control trials and longitudinal studies. Results: Diagnostic criteria consisted of audiograms, questionnaires and patient complaints. The study quality ranged from 21.43% to 85.71%. Overall results found that those treated with cisplatin had more hearing loss and tinnitus than those treated with other therapies. Furthermore, those with hearing loss and tinnitus were more likely to have a lower QoL. Conclusions: There is an urgent need to standardise diagnostics when investigating ototoxicity and its effect on QoL, particularly for research into risk factors, prevention and management.

Impact of Lung Cancer Treatment on Cognitive Functioning

The impact of oncologic treatment for (non)-small-cell lung cancer (NSCLC and SCLC, respectively) on cognition is relevant when deciding which treatment is the most preferable option, especially when curation is not possible. A systematic search of Medline and EMBASE for studies on the effect of treatment on cognition in patients with lung cancer was performed. A total of 39 longitudinal articles were included. Study populations were heterogeneous with regards to stage and treatment type. In the 7 studies concerning SCLC, the median age of patients was between 59 and 68 years. Eighty-six percent of these studies had a loss to follow-up > 10%. Six studies used objective tests to assess cognition. Objective measurements showed a negative effect on attention, memory, and fluency after treatment. Thirty-three studies concerning NSCLC were included. The mean age of patients was between 53 and 77 years. Seventy percent of these studies included patients with stage III and IV NSCLC. Over one-half of the studies had a high rate of loss to follow-up. Eighty-eight percent used objective scales to assess cognitive functioning. Subjective decline of cognitive functioning up to 11.1% was experienced, with recovery at 4 to 6 months. Objective measurement of attention showed improvement over the course of chemotherapy. In SCLC, there is a significant negative effect on attention, memory, and fluency. In NSCLC, the longer term impact of treatment on both subjective and objective cognitive functioning appears limited. Thus, there is no evidence directing treatment choice for NSCLC based on longer term cognitive deficits. Further research is needed to precisely assess the impact of lung cancer treatment on cognition.

Quality of life of patients with lung cancer: A scoping review

Abstract Objective: To characterize scientific publications on the quality of life of people with lung cancer in order to explore current knowledge of the subject, with emphasis on assessment instruments and methodological aspects. Method: A scoping type literature review was performed. Articles were sought in the databases of the Virtual Health Library, in an integrative manner, with the descriptors: Quality of life and Lung Neoplasms, with no date of publication or language restrictions (n=138). The selection of articles was based on inclusion and exclusion criteria defined in the study proposal. Results: We included 18 publications published between 2006 and 2017, the majority (n = 10) of which had a cross-sectional design. Eight different instruments were used to evaluate the quality of life of patients with lung cancer, four of which were specific for people with cancer. There was a prevalence of the use of the European Organization for Research and Treatment of Cancer Care Quality of Life Questionnaire - EORTC QLQ-C30 (n=8). Prospective studies (n=8) assessed quality of life before and after chemotherapy, physical therapy or pulmonary resection. The studies adopted different methodologies and provided conflicting results of quality of life. Cross-sectional studies with comparatively healthy subjects found an inferior quality of life for people with lung cancer. Conclusion: The scoping review contributed to the identification of the multiple evaluated instruments, both generic and specific. It found a lack of homogeneity in the methodological approaches of the studies. Further prospective studies with a specific instrument and methodological standardization to evaluate the quality of life of people with lung cancer are recommended.

Prospective analysis of the association between skeletal-related events and quality of life in patients with advanced lung cancer (CSP-HOR13)

A prospective study has previously reported on the incidence of bone metastasis (BM) and skeletal-related events (SREs) in patients with advanced lung cancer. The aim of the present study was to prospectively investigate how the quality of life (QOL) of patients with advanced lung cancer was affected by SREs. Patients with stage IIIB or IV non-small cell lung cancer (NSCLC) or small cell lung cancer (SCLC) at any stage were followed up every four weeks to determine if they had developed SREs. QOL questionnaires were conducted at enrollment, at 3- and 12-months later and at 1 month after the onset of SREs, using QOL scores including the EuroQOL-5 Dimension (EQ-5D), Functional Assessment of Cancer Therapy-General (FACT-G) and activities of daily living (ADL) scores obtained by the Barthel Index. A total of 274 patients were enrolled in the study. At enrollment the EQ-5D and Barthel Index scores were lower in patients with SREs compared with patients without SREs. A chronological analysis revealed no statistically significant changes in either QOL or ADL in any of the patients. For 14 patients in whom QOL data was collected following the onset of SREs, the evaluation undertaken on the four subscales of the FACT-G revealed a significant decline in emotional functioning following the onset of SREs.

Pain in Platin-Induced Neuropathies: A Systematic Review and Meta-Analysis

Introduction

Platin-induced peripheral neuropathy (PIPN) is a common cause of PN in cancer patients. The aim of this paper is to systematically review the current literature regarding PIPN, with a particular focus on epidemiological and clinical characteristics of painful PIPN, and to discuss relevant management strategies.

Methods

A systematic computer-based literature search was conducted on the PubMed database.

Results

This search strategy resulted in the identification of 353 articles. After the eligibility assessment, 282 articles were excluded. An additional 24 papers were identified by scanning the reference lists. In total, 95 papers met the inclusion criteria and were used for this review. The prevalence of neuropathic symptoms due to acute toxicity of oxaliplatin was estimated at 84.6%, whereas PN established after chemotherapy with platins was estimated at 74.9%. Specifically regarding pain, the reported prevalence of pain due to acute toxicity of oxaliplatin was estimated at 55.6%, whereas the reported prevalence of chronic peripheral neuropathic pain in PIPN was estimated at 49.2%.

Conclusion

Peripheral neuropathy is a common complication in patients receiving platins and can be particularly painful. There is significant heterogeneity among studies regarding the method for diagnosing peripheral neuropathy. Nerve conduction studies are the gold standard and should be performed in patients receiving platins and complaining of neuropathic symptoms post-treatment.

Long-Term and Latent Side Effects of Specific Cancer Types

Although many cancer survivors diagnosed with early-stage disease will outlive their cancer, they may continue to experience long-term and/or latent side effects due to cancer treatment. Many of these side effects are common and contribute to worse quality of life, morbidity, and mortality for cancer survivors. This article summarizes the treatment side effects for several of the most prevalent cancers in the United States.

Effects of Chinese Medicine as Adjunct Medication for Adjuvant Chemotherapy Treatments of Non-Small Cell Lung Cancer Patients

The aim was to evaluate the effects of traditional Chinese medicine (TCM) as a combination medication with adjuvant chemotherapy on postoperative early stage non-small cell lung cancer (NSCLC) patients. The 314 patients with completely resected stage IB, II or IIIA cancers were assigned into vinorelbine plus cisplatin/carboplatin (NP/NC) (control, n = 158) and NP/NC with additional TCM (intervention, n = 156) groups. The primary endpoint was QOL scores; secondary endpoints were the toxicity and safety of the regimens. The NP/NC regimen caused mild (grade 1 or 2) non-hematologic toxic effects in the patients comprising vomiting (43.6%), fatigue (36.9%), pain (23%), dry mouth (27.6%) and diarrhea (7.9%). The incidence of adverse events was significantly lower in the intervention group than in the control group (0.57% vs 4.02%, P = 0.037). Transient severe (grade 3 or 4) hematological toxic effects occurred less often (hemoglobin reduction (11.9 vs 22.5 percent) and total bilirubin increased (to 42.1 vs 46.2%) in the intervention compared to the control group during the 2nd chemotherapy cycle. When combined with adjuvant chemotherapy, TCM led to partial relief of symptoms in addition to a reduction of side-effects and adverse events caused by the NP/NC regimens.

Characterization of Missing Data in Clinical Registry Studies

Patterns of missing data are seldom well-characterized in observational research. This study examined the magnitude of, and factors associated with, missing data across multiple observational studies. Missingness was evaluated for demographic, clinical, and patient-reported outcome (PRO) data from a procedure registry (TOPS), a rare disease (cystic fibrosis) registry (Port-CF), and a comparative effectiveness registry (glaucoma, RiGOR). Generalized linear mixed effects models were fit to assess whether patient characteristics or follow-up methods predicted missingness. Data from 156,707 surgical procedures, 32,118 cystic fibrosis patients, and 2373 glaucoma patients were analyzed. Data were rarely missing for demographics, treatments, and outcomes. Missingness for clinical variables varied by registry and measure and depended on whether a variable was required. Within RiGOR, PRO forms were missing more often when collected by e-mail compared with office-based paper data collection. In Port-CF, missingness varied based on insurance status and sex. Strategic consideration of operational approaches affecting missing data should be performed prior to data collection and assessed periodically during study conduct.

Health related quality of life after oesophagectomy: elderly patients refer similar eating and swallowing difficulties than younger patients

Background

Oesophagectomy for cancer could be safe and worthwhile in selected older patients, but less is known about the effect of oesophagectomy on perceived quality of life of such delicate class of cancer patients. The aim of this study was to evaluate the impact of oesophagectomy for cancer in elderly patients in term of health-related quality of life.

Methods

We retrospectively evaluated all consecutive patients who underwent oesophagectomy for cancer at the Surgical Oncology Unit of the Veneto Institute of Oncology between November 2009 and March 2014. Quality of life was evaluated using EORTC C-30 and OES-18 questionnaires at admission, at discharge and 3 months after surgery. Adjusted multivariable linear mixed effect models were estimated to assess mean score differences (MDs) of selected aspects in older (≥70 years) and younger (<70 years) patients.

Results

Among 109 participating patients, 23 (21.1 %) were at least 70 years old and 86 (78.9 %) were younger than 70 years. Global quality of life was clinically similar between older and younger patients over time (MD 4.4). Older patients reported clinically and statistically significantly worse swallowing saliva (MD 17.4, 95 % C.I. 3.6 to 31.2), choking when swallowing (MD 13.8, 95 % C.I. 5.8 to 21.8) and eating difficulties (MD 20.1 95 % C.I. 7.4 to 32.8) than younger patients only at admission.

Conclusions

Early health-related quality of life perception after surgery resulted comparable in older and younger patients. This result may also be due to some predisposition of the elderly to adapt to the new status.

Elevated β-catenin pathway as a novel target for patients with resistance to EGF receptor targeting drugs

There is a high death rate of lung cancer patients. Epidermal growth factor receptor tyrosine kinase inhibitors (EGFR-TKIs) are effective in some lung adenocarcinoma patients with EGFR mutations. However, a significant number of patients show primary and acquire resistance to EGFR-TKIs. Although the Akt kinase is commonly activated due to various resistance mechanisms, the key targets of Akt remain unclear. Here, we show that the Akt-β-catenin pathway may be a common resistance mechanism. We analyzed gene expression profiles of gefitinib-resistant PC9M2 cells that were derived from gefitinib-sensitive lung cancer PC9 cells and do not have known resistance mechanisms including EGFR mutation T790M. We found increased expression of Axin, a β-catenin target gene, increased phosphorylation of Akt and GSK3, accumulation of β-catenin in the cytoplasm/nucleus in PC9M2 cells. Both knockdown of β-catenin and treatment with a β-catenin inhibitor at least partially restored gefitinib sensitivity to PC9M2 cells. Lung adenocarcinoma tissues derived from gefitinib-resistant patients displayed a tendency to accumulate β-catenin in the cytoplasm. We provide a rationale for combination therapy that includes targeting of the Akt-β-catenin pathway to improve the efficacy of EGFR-TKIs.

Adjuvant chemotherapy in non-small cell lung cancer: state-of-the-art

Adjuvant chemotherapy (AC) plays now a significant role in the treatment of resected non-small cell lung cancer (NSCLC) patients and has become standard in clinical practice. It took more than two decades of clinical research to show its value, but it is has been well established that its benefit translates into a 4-5% absolute increase in 5-year survival according to published meta-analysis. This improvement is obtained with two-drug, Cisplatin-based regimens (multiples choices are acceptable but vinorelbine is the drug with more reported evidence) and usually four courses are recommended. Survival increase is restricted to cases in which there is involvement of lymph nodes (both N1 and N2 levels). For N0 cases AC might be considered, with a lower level of evidence, for tumors larger than 4 cm in diameter. At the present time, molecular predictive factors and gene signatures are investigational. Patient selection is of paramount importance. Proper recovery from surgery and the absence of major comorbidities are essential features. Toxicity is significant, but manageable and transient. Neutropenia is the most relevant side effect due to the risk of febrile neutropenia. The role of timing of administration, adjuvant radiotherapy (RT) and of newer drugs under evaluation is also reviewed.

Adjuvant chemotherapy of completely resected early stage non-small cell lung cancer (NSCLC)

Surgery is regarded as the primary treatment modality for early stage non-small cell lung cancer (NSCLC), but even after complete resection, a substantial percentage of these patients eventually develop local recurrence or distant metastases. Therefore more effective treatment strategies to reduce lung cancer mortality and recurrence rate are needed. Only recently has the use of adjuvant chemotherapy become standard in early stage NSCLC, at least for stage II and resected IIIA NSCLC. Controversies remain about the benefit for stage I patients. Five-year survival improvements of 5% to 10% have been reported with cisplatin-based adjuvant chemotherapy from multiple large randomized phase III clinical trials and meta-analyses. Questions remain as to which patients benefit and which regimens are best. In this paper, important clinical research in the field of adjuvant chemotherapy of NSCLC is reviewed.

Early-stage non-small-cell lung cancer: overview of adjuvant chemotherapy and promising advances

SUMMARY Adjuvant cisplatin-based chemotherapy for early-stage non-small-cell lung cancer has become standard of care, after three recent meta-analyses validated survival benefit of approximately 5% at 5 years. Subgroup analyses, however, demonstrated that the benefit appears largely confined to patients with stage II disease; however, 25–30% of patients with stage I disease are at high risk of relapse and death within 5 years. Therefore, there is a need to predict more accurately which patients are likely to relapse after surgery and thus benefit from adjuvant therapy. Recent studies indicate that molecular biomarkers, gene-expression profiling and gene-mutation analysis may not only identify those tumors that are more likely to respond to adjuvant chemotherapy, but also to specific cytotoxic agents. These novel bioanalyses will allow physicians to deliver personalized medicine that utilizes cancer therapeutic drugs more cost effectively, thereby improving response rates and, hopefully, conferring survival advantage.

Quality of life during chemotherapy in lung cancer patients: results across different treatment lines

Background:

Most lung cancer patients are diagnosed at an advanced disease stage and predominantly receive palliative treatment, which increasingly consists of several chemotherapy lines. We report on patients' quality of life (QOL) to gain knowledge on QOL during and across multiple lines of chemotherapy. This includes patients with (neo)adjuvant therapy up to 3rd or above line palliative chemotherapy.

Methods:

Lung cancer patients receiving outpatient chemotherapy at the Kufstein County Hospital completed an electronic version of the EORTC QLQ-C30. Linear mixed models were used for statistical analysis.

Results:

One hundred and eighty seven patients were included in the study. Surprisingly, irrespective of the chemotherapy line patients reported stable QOL scores during treatment. None of the calculated monthly change rates attained clinical significance, referring to established guidelines that classify a small clinical meaningful change as 5 to 10 points. According to treatment line, 3rd or above line palliative chemotherapy was associated with the worst QOL scores, whereas patients undergoing (neo)adjuvant or 1st line palliative chemotherapy reported fairly comparable QOL.

Conclusion:

The essential finding of our study is that all QOL aspects of the EORTC QLQ-C30 questionnaire remained unchanged during each chemotherapy line in an unselected population of lung cancer patients. Between treatment lines pronounced differences were found, indicating that later palliative chemotherapy lines are associated with higher QOL impairments. These changes in QOL may not primarily be related to the treatment, but rather refer to impairments due to disease progression and may be partly due to a consequence of the prior therapies.

Adjuvant treatment in resected non-small cell lung cancer: current and future issues

The cornerstone of treatment for early-stage non-small cell lung cancer (NSCLC) has been surgical resection. In the last five years two phase III trials have provided evidence of adjuvant platinum-based chemotherapy for completely resected stage II-IIIA patients. We review the evidence supporting adjuvant therapy in early-stage NSCLC; we discuss new issues surrounding adjuvant therapy such as treatment in the elderly-unfit population, treatment toxicity and its influence on outcomes, the importance of histology and gender in adjuvant treatment; and we discuss the future landscape of early-stage NSCLC research, namely, therapeutic strategies exploiting pharmacogenomic and gene-expression profiling, in an attempt to customize the treatment.

Health-related quality of life questionnaires in lung cancer trials: a systematic literature review

BACKGROUND

Lung cancer is one of the leading causes of cancer deaths. Treatment goals are the relief of symptoms and the increase of overall survival. With the rising number of treatment alternatives, the need for comparable assessments of health-related quality of life (HRQoL) parameters grows. The aim of this paper was to identify and describe measurement instruments applied in lung cancer patients under drug therapy.

METHODS

We conducted a systematic literature review at the beginning of 2011 using the electronic database Pubmed.

RESULTS

A total of 43 studies were included in the review. About 17 different measurement instruments were identified, including 5 generic, 5 cancer-specific, 4 lung cancer-specific and 3 symptom-specific questionnaires. In 29 studies at least 2 instruments were used. In most cases these were cancer and lung cancer-specific ones. The most frequently used instruments are the EORTC QLQ-C30 and its lung cancer modules LC13 or LC17. Only 5 studies combined (lung) cancer-specific questionnaires with generic instruments.

CONCLUSIONS

The EORTC-C30 and EORTC-LC13 are the most frequently used health-related quality of life measurement instruments in pharmacological lung cancer trials.

Randomized phase 2 trial on refinement of early-stage NSCLC adjuvant chemotherapy with cisplatin and pemetrexed versus cisplatin and vinorelbine: the TREAT study

BACKGROUND

Adjuvant chemotherapy is beneficial in non-small-cell lung cancer (NSCLC). However, balancing toxicity and efficacy mandates improvement.

PATIENTS AND METHODS

Patients with completely resected stages IB-pT3N1 NSCLC were randomly assigned to either four cycles cisplatin (C: 50 mg/m(2) day (d)1 + 8) and vinorelbine (V: 25 mg/m(2) d1, 8, 15, 22) q4 weeks or four cycles cisplatin (75 mg/m(2) d1) and pemetrexed (Px: 500 mg/m(2) d1) q3 weeks. Primary objective was the clinical feasibility rate (no grade (G)4 neutropenia/thrombocytopenia or thrombocytopenia with bleeding, no G3/4 febrile neutropenia or non-hematological toxicity; no premature withdrawal/death). Secondary objectives were drug delivery and efficacy.

RESULTS

One hundred and thirty two patients were randomized (stages: 38% IB, 10% IIA, 47% IIB, 5% pT3pN1; histology: 43% squamous, 57% non-squamous). The feasibility rates were 95.5% (cisplatin and pemetrexed, CPx) and 75.4% (cisplatin and vinorelbine, CVb) (P = 0.001); hematological G3/4 toxic effects were 10% (CPx) and 74% (CVb) (P < 0.001), non-hematological toxic effects were comparable (33% and 31%, P = 0.798). Delivery of total mean doses was 90% of planned with CPx, but 66% (cisplatin) and 64% (vinorelbine) with CVb (P < 0.0001). The median number of cycles [treatment time (weeks)] was 4 for CPx (11.2) and 3 for CVb (9.9). Time to withdrawal from therapy differed significantly between arms favoring CPx (P < 0.001).

CONCLUSION

Adjuvant chemotherapy with CPx is safe and feasible with less toxicity and superior dose delivery compared with CVb.

Multi-center randomized double-blind controlled clinical study of chemotherapy combined with or without traditional Chinese medicine on quality of life of postoperative non-small cell lung cancer patients

Background

Traditional Chinese medicine (TCM) is a widely applied complementary therapy for cancer patients. It can reduce the chemical drugs induced toxic effects to improve the quality of life (QOL). This study applies the highest quality of clinical trial methodology to examine the role of TCM in improving QOL of postoperative non-small-cell lung cancer patients.

Methods and design

This study is a multi-center, randomized, placebo-controlled, double-blind trial. Four hundred eighty patients will be recruited into seven different research centers in China. These patients that meet the inclusion criteria will be randomized into either a treatment group or a placebo group. Each group will receive treatments of 3-weekly chemotherapy with TCM or placebo for four cycles. The primary outcome will involve the evaluation of QOL and the secondary outcome assessments will include two-year disease-free survival rate and disease-free survival. Other efficacy assessments are changes of TCM symptoms and toxicity. Side effects and safety profile of the therapy would be evaluated at the same time. The investigators expect that TCM therapy combined with chemotherapy is superior to chemotherapy solely in terms of QOL improvement and disease-free survival extension. "Intention-to-treat" analysis will include all randomized participants.

Discussion

The results from the clinical trial will provide evidence for the effectiveness of chemotherapy combined with or without TCM in QOL of postoperative NSCLC patients.

Development and validation of a quantitative real-time polymerase chain reaction classifier for lung cancer prognosis

INTRODUCTION

This prospective study aimed to develop a robust and clinically applicable method to identify patients with high-risk early-stage lung cancer and then to validate this method for use in future translational studies.

METHODS

Three published Affymetrix microarray data sets representing 680 primary tumors were used in the survival-related gene selection procedure using clustering, Cox model, and random survival forest analysis. A final set of 91 genes was selected and tested as a predictor of survival using a quantitative real-time polymerase chain reaction-based assay using an independent cohort of 101 lung adenocarcinomas.

RESULTS

The random survival forest model built from 91 genes in the training set predicted patient survival in an independent cohort of 101 lung adenocarcinomas, with a prediction error rate of 26.6%. The mortality risk index was significantly related to survival (Cox model p < 0.00001) and separated all patients into low-, medium-, and high-risk groups (hazard ratio = 1.00, 2.82, 4.42). The mortality risk index was also related to survival in stage 1 patients (Cox model p = 0.001), separating patients into low-, medium-, and high-risk groups (hazard ratio = 1.00, 3.29, 3.77).

CONCLUSIONS

The development and validation of this robust quantitative real-time polymerase chain reaction platform allows prediction of patient survival with early-stage lung cancer. Utilization will now allow investigators to evaluate it prospectively by incorporation into new clinical trials with the goal of personalized treatment of patients with lung cancer and improving patient survival.

Health-related quality of life in non-small-cell lung cancer: an update of a systematic review on methodologic issues in randomized controlled trials

PURPOSE

This study is an update of a systematic review of health-related quality-of-life (HRQOL) methodology reporting in non-small-cell lung cancer (NSCLC) randomized controlled trials (RCTs). The objective was to evaluate HRQOL methodology reporting over the last decade and its benefit for clinical decision making.

METHODS

A MEDLINE systematic literature review was performed. Eligible RCTs implemented patient-reported HRQOL assessments and regular oncology treatments for newly diagnosed adult patients with NSCLC. Included studies were published in English from August 2002 to July 2010. Two independent reviewers evaluated all included RCTs.

RESULTS

Fifty-three RCTs were assessed. Of the 53 RCTs, 81% reported that there was no significant difference in overall survival (OS). However, 50% of RCTs that were unable to find OS differences reported a significant difference in HRQOL scores. The quality of HRQOL reporting has improved; both reporting of clinically significant differences and statistical testing of HRQOL have improved. A European Organisation for Research and Treatment of Cancer HRQOL questionnaire was used in 57% of the studies. However, reporting of HRQOL hypotheses and rationales for choosing HRQOL instruments were significantly less than before 2002 (P < .05).

CONCLUSION

The number of NSCLC RCTs incorporating HRQOL assessments has considerably increased. HRQOL continues to demonstrate its importance in RCTs, especially in those studies in which no OS difference is found. Despite the improved quality of HRQOL methodology reporting, certain aspects remain underrepresented. Our findings suggest need for an international standardization of HRQOL reporting similar to the CONSORT guidelines for clinical findings.

Health-related quality of life and cancer clinical trials

The measurement of patient-reported outcomes, including health-related quality of life, is a new initiative which has emerged and grown over the past four decades. Following the development of reliable and valid self-report questionnaires, health-related quality of life has been assessed in tens of thousands of patients and a wide variety of cancers. This review is based on a selection of data published in the last decade and is intended primarily for healthcare professionals. The assessments in clinical trials have been particularly useful for elucidating the effects of various cancers and their treatments on patients' lives and have provided additional information that enhances the usual clinical endpoints used for determining the benefits and toxicity of treatment. With growing experience the quality of the health-related quality of studies has improved and, in general, recent studies are more likely to be methodologically robust than those that were performed in earlier decades. Health-related quality of life has become a more accurate predictor of survival than some other clinical parameters, such as performance status. The overall outlook for the routine assessment of patient-reported outcomes in clinical trials is assured and, eventually, it is likely to become a standard part of clinical practice. However, there is still a need for a clear method for determining the clinical meaningfulness of changes in scores. The answer will probably come from the greater use of patient-reported outcomes and the consequent growth of experience that is necessary to make such judgements.

Metrics to assess quality of life after management of early-stage lung cancer

Quality of life (QOL) is a key clinical outcome in patients with lung cancer because of the debilitating nature of the disease and its treatments. In recent years, advances have been made in the assessment of QOL via patient-reported outcomes. A brief history of the evolution of QOL measures in oncology clinical trials and practice is given with specific reference to early-stage lung cancer. The role that QOL can play as a prognostic factor, especially among lung cancer patients, is delineated. The most commonly seen symptoms among lung cancer patients are listed. This review is intended to provide the clinical researcher with a summary of the alternative measures that are both valid and reasonable to consider when assessing QOL in early-stage lung cancer patients. Suggestions for QOL assessment in both a research setting and clinical environment are considered. A review of the most popular QOL assessments in general application to lung cancer and disease-specific measures is provided. An algorithm for selecting appropriate QOL assessments for lung cancer clinical research is provided. The primary conclusion from this work is that scientifically sound investigations into the QOL of early-stage lung cancer patients are feasible and encouraged so that the care of these patients can be optimized.

Assessment of symptom control in patients with cancer in Northwestern Turkey

AIM

The main purpose of this cross-sectional study was to compare symptoms occurring before and after chemotherapy treatment and to investigate the factors affecting those symptoms. The secondary purpose was to determine the most commonly occurring symptoms experienced by the patients with cancer after chemotherapy.

METHODS

Fifty inpatients and outpatients receiving chemotherapy for the first time with various cancer diagnoses and hospitalized in the oncology unit of Trakya University Medical Faculty Hospital between July 2006 and April 2007 were attended to the study. Data were collected using the Edmonton Symptom Assessment Scale (ESAS).

RESULTS

It was discovered that symptoms of fatigue, nausea, loss of appetite, impaired sense of well-being, changes in skin and nails, stomatitis and numbness in hands among chemotherapy patients increased by a statistically significant margin after treatment (p<0.05). Post-chemotherapy symptoms increased markedly (p<0.05) among patients within groups determined by age, gender, marital status, stage of cancer and date of diagnosis. Cross-group comparisons of post-chemotherapy participants analyzed in terms of marital status, clinical stage of disease, and date of diagnosis revealed that fewer symptoms (drowsiness and shortness of breath) increased compared to other symptoms measured along with treatment (p<0.05).

CONCLUSION

We conclude that by considering personal characteristic (i.e. age, gender, etc.) as well as disease-related characteristics (i.e. clinical stage of the disease, etc.), individual nursing care might significantly contribute to the alleviation and management of symptoms.

Adjuvant therapy in non-small cell lung cancer: current and future directions

The cornerstone of treatment for early-stage non-small cell lung cancer (NSCLC) has long been surgical resection. Over the past few years, there has been a paradigm shift to provide adjuvant platinum-based chemotherapy for patients with completely resected stage II-IIIA NSCLC founded on large randomized clinical trials demonstrating longer overall survival with this treatment. Reassuringly, the National Cancer Institute of Canada Cancer Therapeutics Group JBR.10 trial recently reported a continued survival advantage for patients treated with adjuvant chemotherapy after >9 years of median follow-up. In contrast, the gains from using this approach for stage IB disease are less clear, although data from an unplanned subgroup analysis suggest benefit for patients with tumors > or = 4 cm. Herein, we review the evidence supporting adjuvant therapy in early-stage NSCLC patients before discussing key mitigating factors in providing treatment, such as stage of disease and the impact of the new seventh edition of the tumor-node-metastasis classification system. Criteria such as patient age and performance status, as well as the value of appropriate chemotherapy selection, are highlighted as measures to help guide management. The role of postoperative radiotherapy and the future landscape of early-stage NSCLC research are also explored; namely, therapeutic strategies exploiting pharmacogenomic and gene-expression profiling, in an attempt to personalize care, and the integration of novel targeted therapies into adjuvant clinical trials.
