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

ABSTRACT: 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.

Project description:ObjectiveTo determine the benefits of preoperative breathing exercises on hospital length of stay (LOS), pneumonia, postoperative pulmonary complications (PPC), 6-minute walk distance (6MWD), forced expiratory volume in 1 second (FEV1), and health-related quality of life (HRQOL) in patients undergoing surgical lung cancer resection.Data sourcesPubMed, EMBASE, Web of Science Core Collection, and Cochrane Central Register of Controlled Trials were comprehensively searched from inception to March 2021.Study selectionOnly studies including preoperative inspiratory muscle training (IMT) and/or breathing exercises compared with a nontraining control group were included. The meta-analysis was done using Cochrane software for multiple variables including LOS, pneumonia, PPC, 6MWD, FEV1, mortality, and HRQOL.Data extractionTwo authors extracted the data of the selected studies. The primary outcomes were LOS and PPC.Data synthesisA total of 10 studies were included in this meta-analysis, 8 of which had both IMT and aerobic exercise. Pooled data for patients who performed preoperative breathing exercises, compared with controls, demonstrated a decrease in LOS with a pooled mean difference of -3.44 days (95% confidence interval [CI], -4.14 to -2.75; P<.01). Subgroup analysis also demonstrated that LOS was further reduced when breathing exercises were combined with aerobic exercise (χ2, 4.85; P=.03). Preoperative breathing exercises reduce pneumonia and PPCs with an odds ratio of 0.37 (95% CI, 0.18-0.75; P<.01) and 0.37 (95% CI, 0.21-0.65; P<.01), respectively. An increase in 6MWD of 20.2 meters was noted in those performing breathing exercises (95% CI, 9.12-31.21; P<.01). No significant differences were noted in FEV1, mortality, or HRQOL.ConclusionsPreoperative breathing exercises reduced LOS, PPC, and pneumonia and potentially improved 6MWD in patients undergoing surgical lung cancer resection. Breathing exercises in combination with aerobic exercise yielded greater reductions in LOS. Randomized controlled trials are needed to test the feasibility of introducing a preoperative breathing exercise program in this patient population.

Project description:PurposeWe examined long-term clinical outcomes among patients with synchronous oligometastatic non-small cell lung cancer (NSCLC) treated at our institution with definitive thoracic chemoradiation therapy (CRT) and local therapy to all oligometastatic lesions.Methods and materialsA retrospective review identified 38 patients with synchronous oligometastatic NSCLC (≤3 metastatic lesions) who were treated with definitive CRT to the primary tumor and regional lymph nodes between 1999 and 2017 at our institution. Of the 38 patients, 27 patients (71%) received induction chemotherapy, all of whom responded or stabilized with initial systemic therapy before consideration of CRT. Most patients received chemotherapy concurrently with radiation therapy (n = 32; 84%) and local therapy to the metastatic disease site(s) (n = 34; 89%). We assessed patterns of progression or failure, overall survival (OS), progression-free survival (PFS), and toxicities.ResultsThe median follow-up duration was 54.9 months. Most patients (84%) presented with N2 to N3 disease. The brain or central nervous system was the most common site of disease progression and occurred in 16 of 28 patients (57%) experiencing any progression and 10 of 16 patients (63%) who initially presented with brain oligometastases. Median OS was 21.1 months (95% confidence interval [CI], 15.6-49.0 months), and median PFS 9.7 months (95% CI, 8.2-14.4 months). The 1-, 2-, and 4-year OS rates were 75.7%, 45.0%, and 33.7%, respectively. On multivariate analysis, both locoregional progression (hazard ratio: 5.8; 95% CI, 2.2-15.0; P = .0003) and distant progression (hazard ratio: 6.0; 95% CI, 2.3-15.4; P = .0002), when treated as time-dependent covariates, were associated with inferior OS. Grade ≥3 esophagitis occurred in 9% and grade ≥3 pneumonitis in 5% of patients with evaluable data.ConclusionsPatients with synchronous oligometastatic NSCLC and a high regional nodal burden treated with definitive thoracic CRT experienced favorable survival outcomes and low toxicity. At our institution, treating oligometastatic disease with CRT after systemic therapy is incorporated into the treatment plan from the onset of therapy, and we monitor the neuraxis closely for progression during and after treatment. Future research should focus on novel treatment combinations, such as immunotherapy or targeted systemic therapy as appropriate to further improve tumor control and survival.

Project description:ObjectivesTo inform personalised home-based rehabilitation interventions, we sought to gain in-depth understanding of lung cancer survivors' (1) attitudes and perceived self-efficacy towards telemedicine; (2) knowledge of the benefits of rehabilitation and exercise training; (3) perceived facilitators and preferences for telerehabilitation; and (4) health goals following curative intent therapy.DesignWe conducted semi-structured interviews guided by Bandura's Social Cognitive Theory and used directed content analysis to identify salient themes.SettingOne USA Veterans Affairs Medical Center.ParticipantsWe enrolled 20 stage I-IIIA lung cancer survivors who completed curative intent therapy in the prior 1-6 months. Eighty-five percent of participants had prior experience with telemedicine, but none with telerehabilitation or rehabilitation for lung cancer.ResultsParticipants viewed telemedicine as convenient, however impersonal and technologically challenging, with most reporting low self-efficacy in their ability to use technology. Most reported little to no knowledge of the potential benefits of specific exercise training regimens, including those directed towards reducing dyspnoea, fatigue or falls. If they were to design their own telerehabilitation programme, participants had a predominant preference for live and one-on-one interaction with a therapist, to enhance therapeutic relationship and ensure correct learning of the training techniques. Most participants had trouble stating their explicit health goals, with many having questions or concerns about their lung cancer status. Some wanted better control of symptoms and functional challenges or engage in healthful behaviours.ConclusionsFeatures of telerehabilitation interventions for lung cancer survivors following curative intent therapy may need to include strategies to improve self-efficacy and skills with telemedicine. Education to improve knowledge of the benefits of rehabilitation and exercise training, with alignment to patient-formulated goals, may increase uptake. Exercise training with live and one-on-one therapist interaction may enhance learning, adherence, and completion. Future work should determine how to incorporate these features into telerehabilitation.

Project description:ImportanceAmpullary adenocarcinoma is a rare malignant neoplasm that arises within the duodenal ampullary complex. The role of adjuvant therapy (AT) in the treatment of ampullary adenocarcinoma has not been clearly defined.ObjectiveTo determine if long-term survival after curative-intent resection of ampullary adenocarcinoma may be improved by selection of patients for AT directed by histologic subtype.Design, setting, and participantsThis multinational, retrospective cohort study was conducted at 12 institutions from April 1, 2000, to July 31, 2017, among 357 patients with resected, nonmetastatic ampullary adenocarcinoma receiving surgery alone or AT. Cox proportional hazards regression was used to identify covariates associated with overall survival. The surgery alone and AT cohorts were matched 1:1 by propensity scores based on the likelihood of receiving AT or by survival hazard from Cox modeling. Overall survival was compared with Kaplan-Meier estimates.ExposuresAdjuvant chemotherapy (fluorouracil- or gemcitabine-based) with or without radiotherapy.Main outcomes and measuresOverall survival.ResultsA total of 357 patients (156 women and 201 men; median age, 65.8 years [interquartile range, 58-74 years]) underwent curative-intent resection of ampullary adenocarcinoma. Patients with intestinal subtype had a longer median overall survival compared with those with pancreatobiliary subtype (77 vs 54 months; P = .05). Histologic subtype was not associated with AT administration (intestinal, 52.9% [101 of 191]; and pancreatobiliary, 59.5% [78 of 131]; P = .24). Patients with pancreatobiliary histologic subtype most commonly received gemcitabine-based regimens (71.0% [22 of 31]) or combinations of gemcitabine and fluorouracil (12.9% [4 of 31]), whereas treatment of those with intestinal histologic subtype was more varied (fluorouracil, 50.0% [17 of 34]; gemcitabine, 44.1% [15 of 34]; P = .01). In the propensity score-matched cohort, AT was not associated with a survival benefit for either histologic subtype (intestinal: hazard ratio, 1.21; 95% CI, 0.67-2.16; P = .53; pancreatobiliary: hazard ratio, 1.35; 95% CI, 0.66-2.76; P = .41).Conclusions and relevanceAdjuvant therapy was more frequently used in patients with poor prognostic factors but was not associated with demonstrable improvements in survival, regardless of tumor histologic subtype. The value of a multimodality regimen remains poorly defined.
