Alaswad M. Locally advanced non-small cell lung cancer: current issues and recent trends. Rep Pract Oncol Radiother 2023; 28:286-303.

Abstract
The focus of this paper was to review and summarise the current issues and recent trends within the framework of locally advanced (LA) non-small cell lung cancer (NSCLC). The recently proposed 8th tumour-node-metastases (TNM) staging system exhibited significant amendments in the distribution of the T and M descriptors. Every revision to the TNM classification should contribute to clinical improvement. This is particularly necessary regarding LA NSCLC stratification, therapy and outcomes. While several studies reported the superiority of the 8th TNM edition in comparison to the previous 7th TNM edition, in terms of both the discrimination ability among the various T subgroups and clinical outcomes, others argued against this interpretation. Synergistic cytotoxic chemotherapy with radiotherapy is most prevalent in treating LA NSCLC. Clinical trial experience from multiple references has reported that the risk of locoregional relapse and distant metastasis was less evident for patients treated with concomitant radiochemotherapy than radiotherapy alone. Nevertheless, concern persists as to whether major incidences of toxicity may occur due to the addition of chemotherapy. Cutting-edge technologies such as four-dimensional computed tomography (4D-CT) and volumetric modulated arc therapy (VMAT) should yield therapeutic gains due to their capability to conform radiation doses to tumours. On the basis of the preceding notion, the optimum radiotherapy technique for LA NSCLC has been a controversial and much-disputed subject within the field of radiation oncology. Notably, no single-perspective research has been undertaken to determine the optimum radiotherapy modality for LA NSCLC. The landscape of immunotherapy in lung cancer is rapidly expanding. Currently, the standard of care for patients with inoperable LA NSCLC is concurrent chemoradiotherapy followed by maintenance durvalumab according to clinical outcomes from the PACIFIC trial. An estimated 42.9% of patients randomly assigned to durvalumab remained alive at five years, and free of disease progression, thereby establishing a new benchmark for the standard of care in this setting.

Considerations of Medical Preparedness to Assess and Treat Various Populations During a Radiation Public Health Emergency. Radiat Res 2023; 199:301-318.

Abstract
During a radiological or nuclear public health emergency, given the heterogeneity of civilian populations, it is incumbent on medical response planners to understand and prepare for a potentially high degree of interindividual variability in the biological effects of radiation exposure. A part of advanced planning should include a comprehensive approach, in which the range of possible human responses in relation to the type of radiation expected from an incident has been thoughtfully considered. Although there are several reports addressing the radiation response for special populations (as compared to the standard 18-45-year-old male), the current review surveys published literature to assess the level of consideration given to differences in acute radiation responses in certain sub-groups. The authors attempt to bring clarity to the complex nature of human biology in the context of radiation to facilitate a path forward for radiation medical countermeasure (MCM) development that may be appropriate and effective in special populations. Consequently, the focus is on the medical (as opposed to logistical) aspects of preparedness and response. Populations identified for consideration include obstetric, pediatric, geriatric, males, females, individuals of different race/ethnicity, and people with comorbidities. Relevant animal models, biomarkers of radiation injury, and MCMs are highlighted, in addition to underscoring gaps in knowledge and the need for consistent and early inclusion of these populations in research. The inclusion of special populations in preclinical and clinical studies is essential to address shortcomings and is an important consideration for radiation public health emergency response planning. Pursuing this goal will benefit the population at large by considering those at greatest risk of health consequences after a radiological or nuclear mass casualty incident.

Abstract
Purpose Radiation treatment interruption associated with unplanned hospitalization remains understudied. The intent of this study was to benchmark the frequency of hospitalization-associated radiation therapy interruptions (HARTI), characterize disease processes causing hospitalization during radiation, identify factors predictive for HARTI, and localize neighborhood environments associated with HARTI at our academic referral center. Methods and Materials This retrospective review of electronic health records provided descriptive statistics of HARTI event rates at our institutional practice. Uni- and multivariable logistic regression models were developed to identify significant factors predictive for HARTI. Causes of hospitalization were established from primary discharge diagnoses. HARTI rates were mapped according to patient residence addresses. Results Between January 1, 2015, and December 31, 2017, 197 HARTI events (5.3%) were captured across 3729 patients with 727 total missed treatments. The 3 most common causes of hospitalization were malnutrition/dehydration (n = 28; 17.7%), respiratory distress/infection (n = 24; 13.7%), and fever/sepsis (n = 17; 9.7%). Factors predictive for HARTI included African-American race (odds ratio [OR]: 1.48; 95% confidence interval [CI], 1.07-2.06; P = .018), Medicaid/uninsured status (OR: 2.05; 95% CI, 1.32-3.15; P = .0013), Medicare coverage (OR: 1.7; 95% CI, 1.21-2.39; P = .0022), lung (OR: 5.97; 95% CI, 3.22-11.44; P < .0001), and head and neck (OR: 5.6; 95% CI, 2.96-10.93; P < .0001) malignancies, and prescriptions >20 fractions (OR: 2.23; 95% CI, 1.51-3.34; P < .0001). HARTI events clustered among Medicaid/uninsured patients living in urban, low-income, majority African-American neighborhoods, and patients from middle-income suburban communities, independent of race and insurance status. Only the wealthiest residential areas demonstrated low HARTI rates. Conclusions HARTI disproportionately affected socioeconomically disadvantaged urban patients facing a high treatment burden in our catchment population. A complementary geospatial analysis also captured the risk experienced by middle-income suburban patients independent of race or insurance status. Confirmatory studies are warranted to provide scale and context to guide intervention strategies to equitably reduce HARTI events.

Elderly Patients with Locally Advanced and Unresectable Non-Small-Cell Lung Cancer May Benefit from Sequential Chemoradiotherapy. Cancers (Basel) 2021; 13:cancers13184534. [PMID: 34572760 PMCID: PMC8466795 DOI: 10.3390/cancers13184534] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/04/2021] [Revised: 09/01/2021] [Accepted: 09/06/2021] [Indexed: 12/25/2022] Open
Abstract
Simple Summary The combination of chemotherapy and radiotherapy, compared with radiotherapy alone, reduces the risk of local disease recurrence and the risk of distant metastases in patients with locally advanced unresectable non-small-cell lung cancer. Concurrent chemoradiotherapy is the most effective but also has the highest risk of toxicity. Older patients often have comorbidities and a reduced cardio-pulmonary capacity; therefore, they are less often qualified for concurrent chemoradiotherapy due to the predicted too high toxicity. The study documents the sense of considering sequential chemoradiotherapy in the elderly, regardless of whether they are in a good performance status and how many concomitant diseases were recognized earlier in their history. Compared to younger patients, the elderly benefit more from sequential chemoradiotherapy, because with the same toxicity, complete response is achieved more often and distant metastases are less frequently observed, which translates into a significantly longer survival. Abstract Concurrent chemoradiotherapy is recommended for locally advanced and unresectable non-small-cell lung cancer (NSCLC), but radiotherapy alone may be used in patients that are ineligible for combined-modality therapy due to poor performance status or comorbidities, which may concern elderly patients in particular. The best candidates for sequential chemoradiotherapy remain undefined. The purpose of the study was to determine the importance of a patients’ age during qualification for sequential chemoradiotherapy. The study enrolled 196 patients. Older patients (age > 65years) more often had above the median Charlson Comorbidity Index CCI > 4 (p < 0.01) and Simplified Charlson Comorbidity Index SCCI > 8 (p = 0.03), and less frequently the optimal Karnofsky Performance Score KPS = 100 (p < 0.01). There were no significant differences in histological diagnoses, frequency of stage IIIA/IIIB, weight loss, or severity of smoking between older and younger patients. Older patients experienced complete response more often (p = 0.01) and distant metastases less frequently (p = 0.03). Univariable analysis revealed as significant for overall survival: age > 65years (HR = 0.66; p = 0.02), stage IIIA (HR = 0.68; p = 0.01), weight loss > 10% (HR = 1.61; p = 0.04). Multivariable analysis confirmed age > 65years as a uniquely favorable prognostic factor (HR = 0.54; p < 0.01) independent of lung cancer disease characteristics, KPS = 100, CCI > 4, SCCI > 8. Sequential chemoradiotherapy may be considered as favorable in elderly populations.

Abstract
Lung cancer is the leading cause of cancer-associated mortality in the USA. The median age at diagnosis of lung cancer is 70 years, and thus, about one-half of patients with lung cancer fall into the elderly subgroup. There is dearth of high level of evidence regarding the management of lung cancer in the elderly in the three broad stages of the disease including early-stage, locally advanced, and metastatic disease. A major reason for the lack of evidence is the underrepresentation of elderly in prospective randomized clinical trials. Due to the typical decline in physical and physiologic function associated with aging, most elderly do not meet the stringent eligibility criteria set forth in age-unselected clinical trials. In addition to performance status, ideally, comorbidity, cognitive, and psychological function, polypharmacy, social support, and patient preferences should be taken into account before applying prevailing treatment paradigms often derived in younger, healthier patients to the care of the elderly patient with lung cancer. The purpose of this chapter was to review the existing evidence of management of early-stage, locally advanced disease, and metastatic lung cancer in the elderly.

Comorbidity Assessment Using Charlson Comorbidity Index and Simplified Comorbidity Score and Its Association With Clinical Outcomes During First-Line Chemotherapy for Lung Cancer. Clin Lung Cancer 2015; 17:205-213.e1. [PMID: 26589440 DOI: 10.1016/j.cllc.2015.10.002] [Citation(s) in RCA: 28] [Impact Index Per Article: 3.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/23/2015] [Revised: 10/05/2015] [Accepted: 10/13/2015] [Indexed: 01/26/2023]
Abstract
BACKGROUND Limited data is available on comorbidity assessment in patients with lung cancer. The present prospective study assessed the prevalence and association of the Charlson comorbidity index (CCI) and simplified comorbidity score (SCS) with clinical outcomes in patients with newly diagnosed lung cancer undergoing chemotherapy. PATIENTS AND METHODS All patients received histology-guided platinum doublets. The outcomes assessed were overall survival (OS), radiologic responses using Response Evaluation Criteria in Solid Tumors and toxicity using the Common Toxicity Criteria, version 3.0. The groups analyzed were SCS ≤ 9 (n = 173) and > 9 (n = 65) and CCI = 0 (n = 88), 1 (n = 97), and ≥ 2 (n = 53). Correlations of the CCI and SCS were assessed using Spearman's (rho) method. Hazard ratios (HRs) with 95% confidence intervals (CIs) were calculated for the factors affecting OS using Cox proportional hazard (CPH) modeling. RESULTS Most patients had advanced disease (stage IIIB in 33.6%, stage IV in 42.4%). The median SCS was 7 (interquartile range, 7-11), and the median CCI was 1 (interquartile range, 0-1). The correlation between the CCI and SCS was moderate (rho = 0.474; P < .001). Age correlated weakly with both SCS (rho = 0.293; P < .001) and CCI (rho = 0.205; P < .001). The SCS > 9 group (vs. SCS ≤ 9) had a significantly older mean age, patients aged ≥ 70 years, men, smokers, and squamous cell histologic type. The mean age in the CCI groups was 55.2 years for a CCI of 0, 59.6 years for a CCI of 1, and 60.3 years for a CCI of 2, with a statistically significant difference (P = .002). The radiologic responses and toxicity profiles were similar between the SCS and CCI groups. The median OS was 287 days (95% CI, 232-342 days) and did not differ between the SCS and CCI groups. On multivariate CPH analyses, worse OS was independently associated with stage IV disease (adjusted HR, 2.0; 95% CI, 1.4-2.7) and poor performance status (Eastern Cooperative Oncology Group score ≥ 2; adjusted HR, 1.8; 95% CI, 1.1-2.8) but not with comorbidity, histologic type, or age. CONCLUSION The SCS and CCI scores correlated moderately with each other and weakly with age. The presence of comorbidities did not adversely influence clinical outcomes in this Indian cohort of lung cancer patients undergoing first-line chemotherapy.

Abstract
BACKGROUND Clinical trials indicate that the benefit of adding concurrent chemotherapy to radiotherapy of locally advanced non-small cell lung cancer (NSCLC) for fit elderly is similar to the benefit for younger patients. However, since elderly patients are under-represented in most trials, the results might be due to selection bias, thus reports from a cohort of consecutively treated patients are warranted. The current single institution study reports on the influence of age on survival of locally advanced NSCLC patients treated with radiotherapy combined with or without concurrent chemotherapy. MATERIAL AND METHODS Altogether, 478 patients completed radical radiotherapy in doses of 60-66 Gy/30-33 fractions from 1995 to June 2012; 137 of the patients had concurrent chemotherapy. The data was analyzed in age groups<60, 60-69, and ≥70 years. RESULTS In the analyses of overall and lung cancer specific survival the hazard ratio was related to the use of concurrent chemotherapy was 0.49 (95% CI 0.29; 0.82), 0.68 (95% CI 0.48; 0.98) and 1.01 (95% CI 0.67; 1.51) for the age groups<60, 60-69, and ≥70, respectively. CONCLUSION Use of concurrent chemotherapy to radiotherapy of locally advanced NSCLC was associated with a survival benefit in patient younger than 70 years which was not the case for patients older than 70 years, indicating the need to be careful when selecting elderly patients for concurrent chemo-radiation.

Abstract
During radiotherapy to kill femoral hydatid tapeworms, the sciatic nerve surrounding the focus can be easily damaged by the treatment. Thus, it is very important to evaluate the effects of radiotherapy on the surrounding nervous tissue. In the present study, we used three-dimensional, conformal, intensity-modulated radiation therapy to treat bilateral femoral hydatid disease in Meriones meridiani. The focus of the hydatid disease on the left femur was subjected to radiotherapy (40 Gy) for 14 days, and the right femur received sham irradiation. Hematoxylin-eosin staining, electron microscopy, and terminal deoxynucleotidyl transferase-dUTP nick end labeling assays on the left femurs showed that the left sciatic nerve cell structure was normal, with no obvious apoptosis after radiation. Trypan blue staining demonstrated that the overall protoscolex structure in bone parasitized with Echinococcus granulosus disappeared in the left femur of the animals after treatment. The mortality of the protoscolex was higher in the left side than in the right side. The succinate dehydrogenase activity in the protoscolex in bone parasitized with Echinococcus granulosus was lower in the left femur than in the right femur. These results suggest that three-dimensional conformal intensity-modulated radiation therapy achieves good therapeutic effects on the secondary bone in hydatid disease in Meriones meridiani without damaging the morphology or function of the sciatic nerve.

How Do Elderly Poor Prognosis Patients Tolerate Palliative Concurrent Chemoradiotherapy for Locally Advanced Non-Small-Cell Lung Cancer Stage III? A Subset Analysis From a Clinical Phase III Trial. Clin Lung Cancer 2014; 16:183-92. [PMID: 25481662 DOI: 10.1016/j.cllc.2014.08.005] [Citation(s) in RCA: 15] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/17/2014] [Revised: 08/03/2014] [Accepted: 08/26/2014] [Indexed: 12/14/2022]
Abstract
BACKGROUND In a phase III trial of patients with unresectable, locally advanced, stage III non-small-cell lung cancer (NSCLC) with a poor prognosis, palliative concurrent chemoradiotherapy (CRT) provided a significantly better outcome than chemotherapy alone, except among performance status (PS) 2 patients. In the present subgroup analysis, we evaluated the effect on patients aged ≥ 70 years (42% of all included) compared with patients aged < 70 years enrolled in the trial. PATIENTS AND METHODS All patients received 4 courses of intravenous carboplatin and oral vinorelbine. The experimental arm also received radiotherapy (42 Gy in 15 fractions). The included patients were required to have large tumors (> 8 cm), weight loss (> 10% within the previous 6 months) and/or PS 2. RESULTS The overall survival was increased among the CRT patients in both age groups, but the difference was significant only in patients aged < 70 years (median survival, 14.8 vs. 9.7 months; P = .001; age ≥ 70 years, median survival, 10.2 vs. 9.1 months; P = .09). Patients aged ≥ 70 years experienced better preserved health-related quality of life (QOL) and significantly less hematologic toxicity. The 2- and 3-year survival was significantly increased in both age groups receiving CRT. CONCLUSION Elderly patients aged ≥ 70 years with unresectable, stage III, locally advanced, NSLCL and a poor prognosis can tolerate CRT with the doses adjusted to age and palliative intent. These results indicate that CRT can provide both survival and QOL benefits in elderly patients, except for those with PS 2 or worse. The male predominance in the ≥ 70-year-age group and the reduced chemotherapy intensity for the patients aged > 75 years might explain the lack of significant survival improvement among those patients aged ≥ 70 years.

Abstract
Purpose The objective of this study was to evaluate external beam radiotherapy (EBRT) in lung cancer patients who suffer from airway obstruction. Materials and Methods Medical data of 95 patients with a lung mass that obstructed the airway and received EBRT for it were analyzed. Fifty-nine patients (62.1%) had non-small cell lung cancer and 36 patients (37.9%) had small cell lung cancer. Radiotherapy was given at 8 to 45 Gy (median, 30 Gy) in 1 to 15 fractions (median, 10 fractions). The response to EBRT was assessed through changes in radiographic findings and/or subjective symptoms between before and after EBRT. The median follow-up duration was 124 days. The primary end point was the airway-obstruction resolving rate after EBRT. The secondary end points were patient survival and toxic effects of EBRT. Results Improvement of airway obstruction after EBRT on chest X-ray was achieved in 75 of 95 patients (78.9%). The median time for resolving the radiologic findings and/or symptoms of airway obstruction after EBRT was 7 days (range, 1 to 76 days). The 1-year survival rate was significantly higher in responders than non-responders (12.5% vs. 0.0%, p < 0.001). The biologically effective dose of ≥ 39 Gyα/β=10 (p < 0.01) and the longest obstructive lesion of < 6 cm (p=0.04) were significantly associated with a good response to EBRT in resolving the airway obstruction. No one had grade 3 or higher acute and chronic toxicities. Conclusion EBRT is an effective treatment in relieving airway obstruction without severe toxicities in lung cancer patients.

Abstract
Most patients with non-small-cell lung cancer (NSCLC) are elderly but evidence to guide appropriate treatment decisions for this age group is generally scant. Careful evaluation of the elderly should be undertaken to ensure that treatment appropriate for the stage of the tumour is guided by patient characteristics and not by age. The Comprehensive Geriatric Assessment (CGA) remains the preferred option, but briefer tools may be appropriate to select patients for further evaluation. The predicted outcome should be used to guide management decisions together with a reappraisal of polypharmacy. Patient expectations should also be taken into account. Management recommendations are generally similar to those of general guidelines for the NSCLC population, although the risks of surgery and toxicity of chemotherapy and radiotherapy are often increased in the elderly compared with younger patients; therefore, patients should be closely scrutinised and subjected to a CGA to ensure suitability of the planned treatment. If surgery is indicated, then lobectomy is generally the preferred option, although limited resection may be more feasible for some. Radiotherapy with curative intent is an alternative, with stereotactic body radiotherapy the most likely preferred modality. Adjuvant chemotherapy is also an appropriate approach, whereas adjuvant radiotherapy is generally not recommended. Concurrent chemoradiotherapy should be considered for elderly patients with inoperable locally advanced disease and chemotherapy for advanced/metastatic disease. Efforts should also be made to increase participation of elderly patients with NSCLC in clinical trials, thereby enhancing evidence-based treatment decisions for this majority group. This will require overcoming barriers relating to trial design and to physician and patient awareness and attitudes.

Abstract
BACKGROUND Concurrent chemo-radiotherapy (CON-CRT) is recommended for selected patients with stage III non-small cell lung cancer (NSCLC), but utilization varies. We assessed the response to national guidelines introduced in 2004 and the impact on outcomes. MATERIAL AND METHODS Retrospective study of stage III NSCLC patients treated with radical intent non-surgical treatment during 2003-2010 in a university medical center characterized by multidisciplinary assessment, routine use of four-dimensional computed tomography for radiotherapy planning, and rapid implementation of radiotherapy advances. RESULTS Between 2003 and 2010, 319/435 (73%) patients with stage III NSCLC received (chemo) radiotherapy. The number receiving CON-CRT in successive two-year periods increased from 13/48 (27%) - 40/80 (50%) - 63/90 (70%), to 74/101 (73%). Median overall survival (OS) from start of radiotherapy was 18.6 months for CON-CRT (190/319) and 17.4 months for sequential (SEQ), typically hypofractionated, CRT (90/319) (p = 0.78). Eleven months OS with radiotherapy alone (39/319) was significantly shorter (p = 0.006). OS did not differ between the four periods (p = 0.87). CON-CRT was not over-represented in the 16% of patients dying within five months of starting radiotherapy. CONCLUSIONS Between 2003 and 2010, CON-CRT for stage III NSCLC was rapidly and safely increased. However, OS did not increase and, as practiced, did not differ between CON- or SEQ-CRT.

Comparison of toxicity and outcomes of concurrent radiotherapy with carboplatin/paclitaxel or cisplatin/etoposide in stage III non-small cell lung cancer. Cancer Med 2013; 2:916-24. [PMID: 24403265 PMCID: PMC3892396 DOI: 10.1002/cam4.142] [Citation(s) in RCA: 24] [Impact Index Per Article: 2.2] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/27/2013] [Revised: 08/25/2013] [Accepted: 09/02/2013] [Indexed: 12/18/2022] Open
Abstract
Concurrent chemoradiotherapy (CCRT) has become the standard of care for patients with unresectable stage III non-small cell lung cancer (NSCLC). The comparative merits of two widely used regimens: carboplatin/paclitaxel (PC) and cisplatin/etoposide (PE), each with concurrent radiotherapy, remain largely undefined. Records for consecutive patients with stage III NSCLC treated with PC or PE and ≥60 Gy chest radiotherapy between 2000 and 2011 were reviewed for outcomes and toxicity. Survival was estimated using the Kaplan-Meier method and Cox modeling with the Wald test. Comparison across groups was done using the student's t and chi-squared tests. Seventy-five (PC: 44, PE: 31) patients were analyzed. PC patients were older (median 71 vs. 63 years; P = 0.0006). Other characteristics were comparable between groups. With PE, there was significantly increased grade ≥3 neutropenia (39% vs. 14%, P = 0.024) and thrombocytopenia (10% vs. 0%, P = 0.039). Radiation pneumonitis was more common with PC (66% vs. 38%, P = 0.033). Five treatment-related deaths occurred (PC: 3 vs. PE: 2, P = 1.000). With a median follow-up of 51.6 months, there were no significant differences in relapse-free survival (median PC 12.0 vs. PE 11.5 months, P = 0.700) or overall survival (median PC 20.7 vs. PE 13.7 months; P = 0.989). In multivariate analyses, no factors predicted for improved survival for either regimen. PC was more likely to be used in elderly patients. Despite this, PC resulted in significantly less hematological toxicity but achieved similar survival outcomes as PE. PC is an acceptable CCRT regimen, especially in older patients with multiple comorbidities.
