Attachment styles in patients with lung cancer and their spouses: associations with patient and spouse adjustment.

PURPOSE: This study examined attachment styles in patients with lung cancer and their spouses and associations between attachment styles and patient and spouse adjustment. METHODS: One hundred twenty-seven patients with early stage lung cancer completed measures of attachment style, marital quality, self-efficacy, pain, depression, anxiety, and quality of life. Their spouses completed measures of attachment style, marital quality, self-efficacy, caregiver strain, and mood. RESULTS: Analyses indicated that, among patients, those high in either attachment anxiety or avoidance had significantly higher levels of anxiety and poorer social well-being. Attachment avoidance was also significantly associated with higher levels of depression and poorer marital quality and functional well-being. Spouse avoidant attachment was significantly associated with patient reports of increased pain and poorer functional well-being, and spouse anxious attachment was associated with poorer patient marital quality. Among spouses, those high in attachment avoidance reported significantly higher levels of caregiver strain, anger, depressed mood, and poorer marital quality; those high in attachment anxiety reported higher anxious mood. Dyads in which both partners were insecurely attached had significantly poorer adjustment compared to dyads in which both partners reported secure attachment. CONCLUSIONS: These preliminary findings raise the possibility that attachment styles of cancer patients and their spouses as individuals and as a dyad may be important factors affecting adjustment in multiple domains.

A Phase 2 Clinical Trial of Combination Nivolumab, Ipilimumab, and Paclitaxel in Patients With Untreated Metastatic NSCLC: The OPTIMAL Trial.

Introduction: Most patients with advanced NSCLC will experience disease progression and death within 2 years. Novel approaches are needed to improve outcomes. Methods: We conducted an open-label, nonrandomized, phase 2 trial in patients with treatment-naive, advanced NSCLC to assess the safety and efficacy of nivolumab 360 mg every 3 weeks, ipilimumab 1 mg/kg every 6 weeks, and four to six cycles of paclitaxel 80 mg/m2 on days 1 and 8 of every 21-day treatment. The primary end point of the study was median progression-free survival (PFS), with secondary end points of safety, objective response rate, and median overall survival (OS). Results: A total of 46 patients underwent consent and received treatment. The median age was 66 (range: 48-82) years, most had adenocarcinoma (63%), and 50% (23) had programmed death-ligand 1 greater than or equal to 1%. The median follow-up on the study as of October 2021 was 19 months. The primary end point of median PFS was 9.4 months (95% confidence interval [CI]: 5.9-16.6) in all patients regardless of programmed death-ligand 1 expression. The objective response rate for patients in the study was 47.8% (95% CI: 33.4-62.3). The 12-month OS rate was 69.5% (95% CI: 53%-81%), and median OS was not yet reached. Treatment-related grade greater than or equal to 3 adverse events was found in 54.3% of the patients. Conclusions: The toxicity observed was consistent with other reported chemo-immunotherapeutic combinations and was manageable. The primary end point of exceeding median PFS of 9 months was achieved with nivolumab, ipilimumab, and weekly paclitaxel and should be evaluated further in a randomized trial.

The impact of induction chemotherapy and the associated tumor response on subsequent radiation-related changes in lung function and tumor response.

PURPOSE: To assess the impact of induction chemotherapy, and associated tumor shrinkage, on the subsequent radiation-related changes in pulmonary function and tumor response. METHODS AND MATERIALS: As part of a prospective institutional review board-approved study, 91 evaluable patients treated definitively with thoracic radiation therapy (RT) for unresectable lung cancer were analyzed. The rates of RT-associated pulmonary toxicity and tumor response were compared in the patients with and without pre-RT chemotherapy. In the patients receiving induction chemotherapy, the rates of RT-associated pulmonary toxicity and tumor response were compared in the patients with and without a response (modified Response Evaluation Criteria in Solid Tumor criteria) to the pre-RT chemotherapy. Comparisons of the rates of improvements in pulmonary function tests (PFTs) post-RT, dyspnea requiring steroids, and percent declines in PFTs post-RT were compared in patient subgroups using Fisher's exact test, analysis of variance, and linear or logistic regression. RESULTS: The use of pre-RT chemotherapy appears to increase the rate of radiation-induced pneumonitis (p = 0.009-0.07), but has no consistent impact on changes in PFTs. The degree of induction chemotherapy-associated tumor shrinkage is not associated with the rate of subsequent RT-associated pulmonary toxicity. The degree of tumor response to chemotherapy is not related to the degree of tumor response to RT. CONCLUSIONS: Additional study is needed to better clarify the impact of chemotherapy on radiation-associated disfunction.

Assessing the ability of the antiangiogenic and anticytokine agent thalidomide to modulate radiation-induced lung injury.

PURPOSE: Thalidomide has broad anticytokine properties, which might protect normal tissues in patients undergoing chemoradiotherapy. The purpose of this study was to determine the maximal tolerated dose of thalidomide when used in combination with vinorelbine plus thoracic radiotherapy. METHODS AND MATERIALS: Eligible patients had inoperable Stage III non-small-cell lung cancer, a Karnofsky Performance Status>or=70, and life expectancy>or=6 months. Patients underwent pretreatment evaluation of lung function. Radiotherapy consisted of 66 Gy in 6.5 weeks. Vinorelbine was administered i.v. (5 mg/m2) 3 times per week just before radiotherapy. Thalidomide was begun at 50 mg, p.o., on day 1 of chemoradiotherapy and continued once daily for 6 months. Side effects were scored using National Cancer Institute Common Toxicity Criteria. RESULTS: Ten patients were enrolled. Of the first 6 patients, 2 developed major thrombotic events that were believed to be possibly related to thalidomide. The study was suspended and modified to require prophylactic anticoagulation. Of the last 4 patients, 2 developed dose-limiting toxicity attributable to thalidomide; both patients required a dose reduction of thalidomide to <50 mg/day. Because the drug is not available in an oral product providing <50 mg/day, the study was closed. CONCLUSIONS: The combination of thalidomide concurrently with thoracic radiotherapy and vinorelbine resulted in excessive toxicity.

A phase I study of dose-dense topotecan given upfront to standard therapy in patients with small cell lung cancer.

OBJECTIVE: To determine the feasibility and maximum tolerated dose of dose-dense topotecan as induction chemotherapy before standard therapy (carboplatin plus etoposide alone or in combination with radiotherapy) in patients with small cell lung cancer (SCLC). PATIENTS AND METHODS: Chemotherapy-naive patients with SCLC and good performance status were eligible. Three 2-week cycles of dose-dense topotecan administered on days 1-3 with granulocyte colony-stimulating factor support were followed by four cycles of standard carboplatin plus etoposide therapy alone (extensive-stage SCLC) or with radiotherapy (limited-stage SCLC). The dose of topotecan was escalated from 1.5 mg/m2/day to 2.5 mg/m2/day in increments of 0.25 mg/m2/day within cohorts of 3-5 patients each. Dose-limiting toxicity was defined as any grade 3 or 4 toxicity resulting in a treatment reduction or a delay of >3 days. RESULTS: Twenty-two patients with SCLC (5 limited-stage, 17 extensive-stage) were enrolled. Treatment was well tolerated. The dose-limiting toxicities were thrombocytopenia and neutropenia, and the maximum tolerated dose of dose-dense topotecan induction therapy was 2.25 mg/m2/day. Overall, topotecan-related grade 3/4 haematological toxicities included neutropenia (n = 4), thrombocytopenia (n = 3) and febrile neutropenia (n = 1). No grade 4 non-haematological toxicities occurred. Grade 3 adverse events included nausea (n = 2), renal toxicity (n = 1) and anorexia (n = 1). Toxicity during the carboplatin plus etoposide +/- radiotherapy phase of therapy was consistent with that reported in previous trials. The overall response rate was 80% for limited-stage and 76% for extensive-stage SCLC. Median survival was 8 months in patients with limited-stage SCLC and 13.5 months for patients with extensive-stage SCLC. CONCLUSION: The results of this phase I study suggest that a regimen of sequential dose-dense topotecan and carboplatin plus etoposide is feasible, and the preliminary activity observed in patients with SCLC warrants further investigation at a starting dose of topotecan 2.25 mg/m2/day.

Carboplatin/paclitaxel or carboplatin/vinorelbine followed by accelerated hyperfractionated conformal radiation therapy: report of a prospective phase I dose escalation trial from the Carolina Conformal Therapy Consortium.

PURPOSE: To prospectively determine the maximum-tolerated dose of accelerated hyperfractionated conformal radiotherapy (RT; 1.6 Gy bid) for unresectable locally advanced lung cancer (IIB to IIIA/B) following induction carboplatin/paclitaxel (C/T) or carboplatin/vinorelbine (C/N). METHODS: Induction chemotherapy, C/T or C/N, was followed by escalating doses of conformally-planned RT (73.6 to 86.4 Gy in 6.4-Gy increments). Concurrent boost methods delivered 1.6 and 1.25 Gy bid to the gross and clinical target volumes, respectively. RESULTS: Between November 1997 and February 2002, 44 patients were enrolled (median age, 59 years; 59% male; stage III, 98%; median tumor size, 4 cm). Thirty-nine patients completed induction chemotherapy: 19 had a partial response, seven progressed, 15 had no response, and three were not assessable. Chemotherapy-associated toxicities were similar in the two chemotherapy groups. The incidence of grade > or = 3 RT-induced toxicity was 1/13, 2/14, and 4/12 at 73.6, 80, and 86.4 Gy, respectively, thus defining the maximum tolerated dose at approximately 80 Gy. Toxicities were in both lung and esophagus and were similar in the two chemotherapy arms. With a median followup of 34 months in the survivors, the actuarial 2-year survival was 47%, the median survival was 18 months. Fifteen patients had tumor relapse: 5 local failures in the high-dose volume, 2 regional failures outside of the high-dose volume, and 8 distant metastases. CONCLUSION: High-dose conformal twice-daily radiation therapy to approximately 80 Gy appears tolerable in well-selected patients with unresectable lung cancer following either C/T or C/N. Dose-limiting toxicities are mainly pulmonary and esophageal.

Bronchial stenosis: an underreported complication of high-dose external beam radiotherapy for lung cancer?

PURPOSE: To assess the incidence of clinically significant bronchial stenosis in patients treated with high doses (i.e., >70 Gy) of twice-daily external beam radiation therapy (RT). METHODS AND MATERIALS: The outcomes of 103 patients with unresectable non-small-cell lung cancer, treated twice daily to doses ranging from 7080 to 8640 cGy between 1992 and 2001, were analyzed. Most were treated on prospective clinical trials. For the dose-effect comparison, the patients were divided on the basis of the total dose: 67 received 74 Gy (range, 70.8-74.5 Gy; median, 73.6 Gy), 20 received 80 Gy, and 16 received 86 Gy (range, 85.2-86.4 Gy; median, 86.4 Gy). Sixty-six patients received sequential chemotherapy before RT. RT-induced bronchial stenosis was defined as symptomatic airway narrowing diagnosed by bronchoscopy or computed tomography scan without evidence of recurrent tumor in that region. RESULTS: Eight patients developed RT-induced, clinically significant, bronchial stenosis 2-48 months (median, 6 months) after RT. The 1-year and 4-year actuarial rate of stenosis was 7% and 38%, respectively. The median overall survival was 2.5 years (5 of 8 were alive at the writing of this report). A suggestion was also found of a dose-response effect with external beam radiotherapy-induced stenosis, with a rate of 4% and 25% at a dose of approximately 74 Gy and 86 Gy, respectively. CONCLUSION: Radiation therapy-induced bronchial stenosis is a significant clinical complication of dose escalation for lung cancer. This complication has been previously mentioned in the literature, but ours is the largest report to date, and the findings suggest that the risk rises with increasing dose. It is likely that this process would manifest in more patients if their disease were controlled well enough for more prolonged survival.

A phase I study of dexosome immunotherapy in patients with advanced non-small cell lung cancer.

BACKGROUND: There is a continued need to develop more effective cancer immunotherapy strategies. Exosomes, cell-derived lipid vesicles that express high levels of a narrow spectrum of cell proteins represent a novel platform for delivering high levels of antigen in conjunction with costimulatory molecules. We performed this study to test the safety, feasibility and efficacy of autologous dendritic cell (DC)-derived exosomes (DEX) loaded with the MAGE tumor antigens in patients with non-small cell lung cancer (NSCLC). METHODS: This Phase I study enrolled HLA A2+ patients with pre-treated Stage IIIb (N = 4) and IV (N = 9) NSCLC with tumor expression of MAGE-A3 or A4. Patients underwent leukapheresis to generate DC from which DEX were produced and loaded with MAGE-A3, -A4, -A10, and MAGE-3DPO4 peptides. Patients received 4 doses of DEX at weekly intervals. RESULTS: Thirteen patients were enrolled and 9 completed therapy. Three formulations of DEX were evaluated; all were well tolerated with only grade 1-2 adverse events related to the use of DEX (injection site reactions (N = 8), flu like illness (N = 1), and peripheral arm pain (N = 1)). The time from the first dose of DEX until disease progression was 30 to 429+ days. Three patients had disease progression before the first DEX dose. Survival of patients after the first DEX dose was 52-665+ days. DTH reactivity against MAGE peptides was detected in 3/9 patients. Immune responses were detected in patients as follows: MAGE-specific T cell responses in 1/3, increased NK lytic activity in 2/4. CONCLUSION: Production of the DEX vaccine was feasible and DEX therapy was well tolerated in patients with advanced NSCLC. Some patients experienced long term stability of disease and activation of immune effectors.

Topotecan in the treatment of elderly patients with relapsed small-cell lung cancer.

BACKGROUND: Almost 70% of all patients with lung cancer in the United States are>65 years of age, and the incidence of small-cell lung cancer (SCLC) increases with age until the eighth decade of life. However, elderly patients are underrepresented in clinical trials and are often suboptimally treated. The validity of age as a prognostic factor for toxicity or survival remains controversial. PATIENTS AND METHODS: To investigate the safety and efficacy of topotecan (an approved treatment for relapsed SCLC) in older patients, we performed a retrospective analysis in patients >or= 65 years of age versus patients < 65 years of age from 5 large topotecan trials. In all 5 trials, patients received topotecan 1.5 mg/m2 per day via a 30-minute intravenous infusion on days 1 through 5 of a 21-day cycle. Efficacy and tolerability outcomes were assessed for both age groups. RESULTS: Topotecan was similarly tolerated in both age groups, with generally manageable hematologic toxicity. The incidence, duration, and onset of severe hematologic toxicities did not vary significantly with age. In the<65 age group, grade 4 neutropenia and leukopenia were reported in 72% and 32% of patients, respectively; in the >or= 65 age group, grade 4 neutropenia and leukopenia were reported in 77% and 31% of patients, respectively. Grade 4 thrombocytopenia was less common in the<65 age group. Nonhematologic toxicities, median time to progression, and overall survival were comparable between groups. CONCLUSION: This is the first demonstration of the safety and efficacy of topotecan in older patients with recurrent SCLC. Future studies are needed to fully characterize the role of topotecan in the treatment of older patients.

A pilot study investigating the utility of the cognitive-behavioral model of insomnia in early-stage lung cancer patients.

This pilot study investigated the utility of a cognitive-behavioral model in understanding insomnia in early-stage lung cancer patients. Nineteen patients meeting criteria for insomnia and a comparison group of 13 patients not meeting these criteria completed questionnaires assessing dysfunctional sleep-related thoughts, poor sleep hygiene, lung cancer symptoms, mood, quality of life, and insomnia symptoms. Participants also completed standard sleep logs and wore an Actiwatch while sleeping each day for 7 days. Findings indicated that the insomnia group reported significantly more dysfunctional sleep-related thoughts, higher levels of pain and anxiety, and lower quality of life than those in the comparison group. Men in the insomnia group reported significantly higher levels of fatigue than men in the comparison group, whereas women demonstrated no group differences. These pilot findings support the utility of the cognitive-behavioral model in understanding insomnia in early-stage lung cancer patients and the hypothesis that insomnia is related to poor clinical status.

Serum CYFRA 21-1 in advanced stage non-small cell lung cancer: an early measure of response.

OBJECTIVES: Our objective was to test the prognostic importance of both the pretreatment level and change in serum CYFRA 21-1 after one cycle of chemotherapy in patients with advanced non-small cell lung cancer (NSCLC) and to compare these two CYFRA variables to routine clinical stage and response as measured by imaging. PATIENTS AND METHODS: Our patients consisted of 58 with advanced NSCLC who were treated with chemotherapy. Fourteen were stage IIIa, 8 stage IIIb, and 36 stage IV, and none had received previous treatment. The choice of chemotherapy was left to the discretion of the treating physicians. We collected two serum samples, one before the first cycle of chemotherapy and the second before the second cycle, and analyzed these for serum CYFRA 21-1 using an electrochemiluminescence immunoassay and the ElecSys 2010 system (Roche Diagnostics Corp., Indianapolis, IN). We expressed changes in CYFRA in terms of the natural ratio logarithm of post-treatment to pretreatment CYFRA, and we used the Cox proportional hazards model to analyze survival time. RESULTS: Patients experienced an average drop of 27% in serum CYFRA after the first cycle of chemotherapy. Furthermore, the Cox model demonstrated that both the initial natural logarithm of serum CYFRA and presence of >27% drop in CYFRA were significantly related to subsequent survival (model P < 0.0006), but neither clinical stage nor clinical response related to survival (P > 0.1). CONCLUSION: In advanced stage NSCLC, the initial level of serum CYFRA appears to provide more prognostic information than clinical stage. Furthermore, a drop of >27% in CYFRA after one cycle of therapy adds prognostic information, so that this threshold appears to be an early measure of response to chemotherapy.

Perceptions of patients' self-efficacy for managing pain and lung cancer symptoms: correspondence between patients and family caregivers.

This study examined the degree of correspondence between lung cancer patients and their family caregivers in their perceptions of the patients' self-efficacy for managing pain and other symptoms of lung cancer, and the association of this correspondence to demographic, disease, and psychosocial variables. Thirty patients who were newly diagnosed with lung cancer and their primary family caregivers completed telephone interviews assessing the patient's symptoms, the patient's self-efficacy for managing symptoms, the quality of the relationship between the patient and caregiver, patient and caregiver psychological distress, and caregiver strain. Although patients and their caregivers showed a moderate degree of agreement in their perceptions of the patient's self-efficacy for managing pain and other symptoms, there was considerable variability in the degree of congruence. Factors that contributed to lower levels of congruence included low patient-rated self-efficacy, female gender of the patient, high patient psychological distress, and high caregiver strain. Caregivers were about evenly split in their tendency to overestimate versus underestimate the patient's self-efficacy. A poorer quality of relationship between the caregiver and the patient (as rated by the patient), high levels of patient-rated symptoms, and high levels of caregiver strain were associated with caregivers overestimating patient self-efficacy.

Routine use of approximately 60 Gy once-daily thoracic irradiation for patients with limited-stage small-cell lung cancer.

PURPOSE: To review the outcome of patients with limited-stage small-cell lung cancer receiving daily thoracic irradiation (RT) to approximately 60 Gy. METHODS AND MATERIALS: The records of patients treated with RT for limited-stage small-cell lung cancer between 1991 and 1999 at Duke University were retrospectively reviewed. Sixty-five patients were identified who had received continuous course once-daily 1.8-2 Gy fractions to approximately 60 Gy (range 58-66). All patients received chemotherapy (CHT); 32 received concurrent RT/CHT and 33 sequential CHT and then RT. Prophylactic cranial RT was administered to 17 patients. The time from diagnosis to local failure, tumor progression, and death was assessed using actuarial methods. The median follow-up for all patients was 16.7 months and for surviving patients was 29.6 months. The median age was 64 years (range 36-83), and the median Karnofsky performance status was 80 (range 50-100). RESULTS: The 3-year actuarial rate of local failure, progression-free survival, and overall survival was 40%, 25%, and 23%, respectively. One case of acute Grade 3 esophagitis developed. Ten late complications occurred: four pulmonary, two esophageal, two infectious, one leukemia, and one retinal toxicity with prophylactic cranial RT. Six were mild and resolved with treatment. CONCLUSION: CHT plus approximately 60 Gy of once-daily RT for limited-stage small-cell lung cancer was generally well tolerated. The survival rates were less than have been reported using 45 Gy in 1.5-Gy twice-daily fractions (2-year overall survival rate 47% compared with 30% in this study), but may be comparable because fewer than one-half our patients received concurrent CHT/RT and only 26% received prophylactic cranial RT. The relatively low rate of normal tissue morbidity in our patients supports the use of conventional once-daily fractionation to > or = 60 Gy. A randomized trial would be required to compare the outcomes after maximally tolerated dose twice-daily RT vs. maximally tolerated dose daily RT.

Risk of long-term complications after TFG-beta1-guided very-high-dose thoracic radiotherapy.

PURPOSE: To report the incidence of late complications in long-term survivors of very-high-dose thoracic radiotherapy (RT) treated on a prospective clinical trial. METHODS AND MATERIALS: Patients with locally advanced or medically inoperable non-small-cell lung cancer received three-dimensional conformal RT to the primary tumor and radiographically involved lymph nodes to a dose of 73.6 Gy at 1.6 Gy twice daily. If the plasma transforming growth factor-beta1 (TGF-beta1) level was normal after 73.6 Gy, additional twice-daily RT was delivered to successively higher total doses until the maximal tolerated dose was reached. Patients within a given dose level were followed for 6 months before escalation to the next dose level was permitted. Late complications were defined according to Radiation Therapy Oncology Group/European Organization for Research and Treatment of Cancer criteria. RESULTS: Thirty-eight patients were enrolled between 1996 and 1999. Twenty-four patients were not eligible for radiation dose escalation beyond 73.6 Gy because of persistently abnormal TGF-beta1 levels. Fourteen patients received dose escalation (80 Gy in 8; 86.4 Gy in 6). Grade 3 or greater late complications occurred in 4 of 24, 1 of 8, and 2 of 6 patients treated to 73.6, 80, and 86.4 Gy, respectively. The corresponding patient numbers with late Grade 4-5 toxicity were 3 of 24, 0 of 6, and 0 of 8. Overall, 7 (18%) of the 38 patients developed Grade 3-5 late toxicity. Nonpulmonary complications predominated (4 of 7). Five (71%) of seven serious complications developed within 11 months after RT; however, the remaining two complications (29%) occurred very late (at 43 and 62 months). The 5-year actuarial risk of late Grade 3-5 complications was 33%. CONCLUSION: Long-term survivors of very-high-dose RT for non-small-cell lung cancer have a significant risk of severe treatment-related complications. At these high dose levels, the predominant toxicity may no longer be pulmonary. All Grade 4-5 complications occurred in patients whose dose was limited to 73.6 Gy because of a persistently elevated TGF-beta1. Thus, persistently elevated plasma TGF-beta1 levels toward the end of RT may identify patients at greatest risk of severe complications.

Satisficing in hypothesis generation.

Research in hypothesis generation suggests that people might act as satisficers and be less likely to generate plausible alternative hypotheses when they already have a hypothesis that accounts for the data in hand. Three experiments simulated scientific hypothesis development. In all 3, participants who had been given a hypothesis consistent with available data generated proportionally fewer of the simplest alternative hypotheses than participants given no such satisficing hypothesis. Furthermore, participant satisficing occurred regardless of whether the provided hypothesis was generated a priori or post hoc and despite high incentives for completeness. Limitations and implications of these findings are discussed for hypothesis development and the practice of taking post hoc hypotheses suggested by one's results and presenting them as a priori hypotheses.

Safety and effectiveness of bevacizumab-containing treatment for non-small-cell lung cancer: final results of the ARIES observational cohort study.

INTRODUCTION: Bevacizumab, a recombinant humanized monoclonal antibody against vascular endothelial growth factor, was approved by the US Food and Drug Administration for the treatment of advanced non-small-cell lung cancer (NSCLC) in combination with carboplatin and paclitaxel. ARIES (Avastin Regimens: Investigation of Effectiveness and Safety), a prospective observational cohort study, evaluated outcomes in a large, community-based population of patients with first-line NSCLC. METHODS: From 2006 to 2009, ARIES enrolled patients with locally advanced or metastatic NSCLC who were eligible for bevacizumab, excluding those with predominantly squamous histology. Patients were required to provide informed consent and to have initiated bevacizumab with chemotherapy within 4 months before enrollment. There were no protocol-defined treatments or assessments. The dosing of bevacizumab and chemotherapy, and the choice of chemotherapy regimen, was at the discretion of the treating physician. RESULTS: ARIES enrolled 1967 patients with first-line NSCLC. At study closure, median follow-up was 12.5 months (range, 0.2-65.5). Median age was 65 years (range, 31-93), and 252 patients (12.8%) identified as never smokers. Median progression-free survival was 6.6 months (95% confidence interval, 6.3-6.9), and median overall survival was 13.0 months (95% confidence interval, 12.2-13.8) with first-line bevacizumab plus chemotherapy. Incidences of bevacizumab-associated adverse events (19.7% overall) were consistent with those in randomized controlled trials of bevacizumab in NSCLC. CONCLUSION: Results from ARIES demonstrate similar outcomes to randomized controlled trials of bevacizumab when added to standard chemotherapy in a real-world patient population with advanced NSCLC.

Assessment of the impact of adjunctive proactive telephone counseling to promote smoking cessation among lung cancer patients' social networks.

PURPOSE: When a patient is diagnosed with lung cancer, members of his/her social network may be more likely to engage in smoking cessation efforts. Proactive telephone counseling combined with a tailored self-directed intervention may be more effective at promoting smoking cessation than a tailored self-directed intervention alone. DESIGN: Randomized controlled trial. SETTING: Four clinical sites. SUBJECTS: Current smokers who are family members and close friends of patients with lung cancer. INTERVENTION: Six counselor-initiated counseling calls using motivational interviewing techniques and focusing on teaching adaptive coping skills based on the transactional model of stress and coping along with tailored self-directed materials (including nicotine patches, if not contraindicated) (n  =  245) vs. tailored self-directed materials (including nicotine patches, if not contraindicated) (n  =  251). MEASURES: Participants were surveyed at baseline and at 2 weeks, 6 months, and 12 months postintervention. The outcome was 7-day point prevalent abstinence. ANALYSIS: The objective of this study was to test for arm differences in smoking cessation rates at 2 weeks and 6 months postintervention (primary) and at 12 months postintervention (secondary). RESULTS: We found no overall effect of the proactive intervention on cessation rates. Among younger participants (age <50), the cessation rate in the intervention group was higher than in the control group at 2 weeks postintervention (16% vs. 4%, p  =  .046). For older participants (age >50), there were no group differences. CONCLUSION: Proactive telephone counseling focusing on adaptive coping skills was difficult to implement among smokers in lung cancer patients' social network. Although this study did not demonstrate any added benefit to cessation rates, this null finding may be a result of an intervention that was weaker than intended, owing to difficulties in completing the counseling phone calls. We discuss lessons learned and areas for future research in this special population.

Randomized phase II study of pemetrexed, carboplatin, and thoracic radiation with or without cetuximab in patients with locally advanced unresectable non-small-cell lung cancer: Cancer and Leukemia Group B trial 30407.

PURPOSE: Cancer and Leukemia Group B conducted a randomized phase II trial to investigate two novel chemotherapy regimens in combination with concurrent thoracic radiation therapy (TRT). PATIENTS AND METHODS: Patients with unresectable stage III non-small-cell lung cancer (NSCLC) were randomly assigned to carboplatin (area under the curve, 5) and pemetrexed (500 mg/m(2)) every 21 days for four cycles and TRT (70 Gy; arm A) or the same treatment with cetuximab administered concurrent only with TRT (arm B). Patients in both arms received up to four cycles of pemetrexed as consolidation therapy. The primary end point was the 18-month overall survival (OS) rate; if the 18-month OS rate was ≥ 55%, the regimen(s) would be considered for further study. RESULTS: Of the 101 eligible patients enrolled (48 in arm A and 53 in arm B), 60% were male; the median age was 66 years (range, 32 to 81 years); 44% and 35% had adenocarcinoma and squamous carcinoma, respectively; and more patients enrolled onto arm A compared with arm B had a performance status of 0 (58% v 34%, respectively; P = .04). The 18-month OS rate was 58% (95% CI, 46% to 74%) in arm A and 54% (95% CI, 42% to 70%) in arm B. No significant difference in OS between patients with squamous and nonsquamous NSCLC was observed (P = .667). The toxicities observed were consistent with toxicities associated with concurrent chemoradiotherapy. CONCLUSION: The combination of pemetrexed, carboplatin, and TRT met the prespecified criteria for further evaluation. This regimen should be studied further in patients with locally advanced unresectable nonsquamous NSCLC.

Caregiver-assisted coping skills training for lung cancer: results of a randomized clinical trial.

CONTEXT: Lung cancer is one of the most common cancers in the United States and is associated with high levels of symptoms, including pain, fatigue, shortness of breath, and psychological distress. Caregivers and patients are adversely affected. However, previous studies of coping skills training (CST) interventions have not been tested in patients with lung cancer nor have systematically included caregivers. OBJECTIVES: This study tested the efficacy of a caregiver-assisted CST protocol in a sample of patients with lung cancer. METHODS: Two hundred thirty-three lung cancer patients and their caregivers were randomly assigned to receive 14 telephone-based sessions of either caregiver-assisted CST or education/support involving the caregiver. Patients completed measures assessing pain, psychological distress, quality of life (QOL), and self-efficacy for symptom management; caregivers completed measures assessing psychological distress, caregiver strain, and self-efficacy for helping the patient manage symptoms. RESULTS: Patients in both treatment conditions showed improvements in pain, depression, QOL, and self-efficacy, and caregivers in both conditions showed improvements in anxiety and self-efficacy from baseline to four-month follow-up. Results of exploratory analyses suggested that the CST intervention was more beneficial to patients/caregivers with Stage II and III cancers, whereas the education/support intervention was more beneficial to patients/caregivers with Stage I cancer. CONCLUSION: Taken together with the broader literature in this area, results from this study suggest that psychosocial interventions can lead to improvements in a range of outcomes for cancer patients. Suggestions for future studies include the use of three-group designs (e.g., comparing two active interventions with a standard-care control) and examining mechanisms of change.
