Abstract
Cavitating lung tumors occur in approximately 10-15% of the patients, are more commonly associated with squamous histology, and are typically located in the lung parenchyma. Herein we describe an exceedingly rare series of 5 patients, 4 of whom treatment-naïve, whose tumor caused the disruption of the normal airway anatomy at the level of lobar or segmental bronchi, leading to the formation of an endoscopically-visible cavity which ended up in the lung parenchyma or even into the pleural space. Sex (3 males, 2 females), smoking habit (2 never smokers, 2 former smokers, 1 current smoker), and histology (3 adenocarcinoma, 2 squamous cell carcinoma) were heterogeneous, but the 4 patients treatment-naïve presented with metastatic disease, poor ECOG performance status, similar clinical complaints of long duration, and lack of actionable mutations. The only patient who exhibited a meaningful response to treatment had the lowest symptoms' duration, the smallest size of the cavitated mass, and the best performance status at the time of diagnosis. This series provides the first comprehensive description of a rare presentation of lung cancer characterized by similar clinical complaints, delayed diagnosis and poor prognosis.

Comparison of post-chemoradiotherapy pneumonitis between Asian and non-Asian patients with locally advanced non-small cell lung cancer: a systematic review and meta-analysis. EClinicalMedicine 2023; 64:102246. [PMID: 37781162 PMCID: PMC10539643 DOI: 10.1016/j.eclinm.2023.102246] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/22/2023] [Revised: 08/28/2023] [Accepted: 09/13/2023] [Indexed: 10/03/2023] Open
Abstract
Background Pneumonitis is a common complication for patients with locally advanced non-small cell lung cancer undergoing definitive chemoradiotherapy (CRT). It remains unclear whether there is ethnic difference in the incidence of post-CRT pneumonitis. Methods PubMed, Embase, Cochrane Library, and Web of Science were searched for eligible studies from January 1, 2000 to April 30, 2023. The outcomes of interest were incidence rates of pneumonitis. The random-effect model was used for statistical analysis. This meta-analysis was registered with PROSPERO (CRD42023416490). Findings A total of 248 studies involving 28,267 patients were included. Among studies of CRT without immunotherapy, the pooled rates of pneumonitis for Asian patients were significantly higher than that for non-Asian patients (all grade: 66.8%, 95% CI: 59.2%-73.9% vs. 28.1%, 95% CI: 20.4%-36.4%; P < 0.0001; grade ≥2: 25.1%, 95% CI: 22.9%-27.3% vs. 14.9%, 95% CI: 12.0%-18.0%; P < 0.0001; grade ≥3: 6.5%, 95% CI: 5.6%-7.3% vs. 4.6%, 95% CI: 3.4%-5.9%; P = 0.015; grade 5: 0.6%, 95% CI: 0.3%-0.9% vs. 0.1%, 95% CI: 0.0%-0.2%; P < 0.0001). Regarding studies of CRT plus immunotherapy, Asian patients had higher rates of all-grade (74.8%, 95% CI: 63.7%-84.5% vs. 34.3%, 95% CI: 28.7%-40.2%; P < 0.0001) and grade ≥2 (34.0%, 95% CI: 30.7%-37.3% vs. 24.6%, 95% CI: 19.9%-29.3%; P = 0.001) pneumonitis than non-Asian patients, but with no significant differences in the rates of grade ≥3 and grade 5 pneumonitis. Results from subgroup analyses were generally similar to that from the all studies. In addition, the pooled median/mean of lung volume receiving ≥20 Gy and mean lung dose were relatively low in Asian studies compared to that in non-Asian studies. Interpretation Asian patients are likely to have a higher incidence of pneumonitis than non-Asian patients, which appears to be due to the poor tolerance of lung to radiation. Nevertheless, these findings are based on observational studies and with significant heterogeneity, and need to be validated in future large prospective studies focusing on the subject. Funding None.

Abstract
Although non-small-cell lung cancer occasionally presents as cavitary lesions, it is rare for small-cell lung cancer (SCLC) to present or progress in such a manner. If a cavitary lesion is seen in the setting of small-cell lung carcinoma, infectious etiologies must be excluded first. We present the case of a 43-year-old man with refractory SCLC that progressed despite two lines of therapy, and who was ultimately found to have recurrent adenopathy and numerous widespread cavitary lung nodules. Fine-needle aspiration of a hilar lymph node revealed extensively necrotic SCLC, while bronchoalveolar cultures grew Aspergillus fumigatus and Candida albicans. The patient was subsequently treated with voriconazole; however, despite these measures, his overall clinical course deteriorated and the patient ultimately succumbed to his illness. Aspergillosis is a major cause of cavitary lung lesions, especially in immunocompromised patients. Our patient with refractory stage four SCLC was found to have several cavitary lung lesions. Before assuming that cavitary lesions are neoplastic, evaluation for aspergillosis should be conducted, particularly in SCLC patients. Although invasive fungal infections are often missed, it may be prudent to conduct such testing because aspergillosis is a treatable condition and the treatment can improve a patient’s hospitalization and overall clinical course.

J Med Imaging Radiat Oncol 2020; 64:779-786. [PMID: 32705779 DOI: 10.1111/1754-9485.13087] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/11/2020] [Revised: 06/21/2020] [Accepted: 06/28/2020] [Indexed: 11/28/2022]
Abstract
INTRODUCTION To correlate tumour grading and prognostic immunohistochemical markers of lung cancer with simultaneously acquired standardised uptake values (SUV) and apparent diffusion coefficient (ADC) derived from hybrid PET/MRI. METHODS In this retrospective study, 55 consecutive patients (mean age 62.5 ± 9.2 years) with therapy-naïve, histologically proven lung cancer were included. All patients underwent whole-body PET/MRI using 18F-flourdeoxyglucose (18F-FDG) as a radiotracer. Diffusion-weighted imaging of the chest (DWI, b-values: 0, 500, 1000 s/mm2 ) was performed simultaneously with PET acquisition. Histopathological tumour grading was available in 43/55 patients. In 15/55 patients, immunohistochemical markers, that is, phospho-AKT Ser473 (pAKTS473), phosphorylated extracellular signal-regulated kinase (pERK), phosphatase and tensin homolog (PTEN), and human epidermal growth factor receptor 2 (erbB2) were available. RESULTS The average SUVmax, SUVmean, ADCmin and ADCmean in lung cancer primaries were 12.6 ± 5.9, 7.7 ± 4.6, 569.9 ± 96.1 s/mm2 and 825.8 ± 93.2 s/mm2 , respectively. We found a significant inverse correlation between the ADCmin and SUVmax (r = -0.58, P < 0.001) as well as between the ADCmin and SUVmean (r = -0.44, P < 0.001). Tumour grading showed a significant positive correlation with SUVmax and SUVmean (R = 0.34 and R = 0.31, both P < 0.05) and a significant inverse correlation with ADCmin and ADCmean (r = -0.30 and r = -0.40, both P < 0.05). In addition, erbB2 showed a significant inverse correlation with SUVmax and SUVmean (r = -0.50 and r = -0.49, both P < 0.05). The other immunohistochemical markers did not show any significant correlation. CONCLUSION 18F-FDG-PET/MRI showed weak to moderate correlations between SUV, ADC, tumour grading and erbB2-expression of lung cancer. Hence, 18F-FDG-PET/MRI may, to some extent, offer complementary information to the histopathology of lung cancer, for the evaluation of tumour aggressiveness and treatment response.

Prognostic factors for overall survival of stage III non-small cell lung cancer patients on computed tomography: A systematic review and meta-analysis. Radiother Oncol 2020; 151:152-175. [PMID: 32710990 DOI: 10.1016/j.radonc.2020.07.030] [Citation(s) in RCA: 10] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/27/2020] [Revised: 07/15/2020] [Accepted: 07/15/2020] [Indexed: 12/15/2022]
Abstract
INTRODUCTION Prognosis prediction is central in treatment decision making and quality of life for non-small cell lung cancer (NSCLC) patients. However, conventional computed tomography (CT) related prognostic factors may not apply to the challenging stage III NSCLC group. The aim of this systematic review was therefore to identify and evaluate CT-related prognostic factors for overall survival (OS) of stage III NSCLC. METHODS The Medline, Embase, and Cochrane electronic databases were searched. After study selection, risk of bias was estimated for the included studies. Meta-analysis of univariate results was performed when sufficient data were available. RESULTS 1595 of the 11,996 retrieved records were selected for full text review, leading to inclusion of 65 studies that reported data of 144,513 stage III NSCLC patients andcompromising 26 unique CT-related prognostic factors. Relevance and validity varied substantially, few studies had low relevance and validity. Only four studies evaluated the added value of new prognostic factors compared with recognized clinical factors. Included studies suggested gross tumor volume (meta-analysis: HR = 1.22, 95%CI: 1.05-1.42), tumor diameter, nodal volume, and pleural effusion, are prognostic in patients treated with chemoradiation. Clinical T-stage and location (right/left) were likely not prognostic within stage III NSCLC. Inconclusive are several radiomic features, tumor volume, atelectasis, location (pulmonary lobes, central/peripheral), interstitial lung abnormalities, great vessel invasion, pit-fall sign, and cavitation. CONCLUSIONS Tumor-size and nodal size-related factors are prognostic for OS in stage III NSCLC. Future studies should carefully report study characteristics and contrast factors with guideline recognized factors to improve evidence evaluation and validation.

Risk Factors for Fatal Pulmonary Hemorrhage following Concurrent Chemoradiotherapy in Stage 3B/C Squamous-Cell Lung Carcinoma Patients. JOURNAL OF ONCOLOGY 2018; 2018:4518935.

Abstract
We aimed to identify the fatal pulmonary hemorrhage- (FPH-) related risk factors in stage 3B/C squamous-cell lung carcinoma (SqCLC) patients treated with definitive concurrent chemoradiotherapy (C-CRT). Medical records of 505 stage 3B/C SqCLC patients who underwent 66 Gy radiotherapy plus 1-3 cycles of concurrent chemotherapy with available pretreatment thoracic computerized tomography scans were retrospectively analyzed. Primary end-point was the identification of FPH-related risk factors. Examined factors included the basal patient and tumor characteristics with specific emphasis on the tumor cavitation (TC) status, tumor size (TS) and cavitation size (CS), tumor volume and cavitation volume (TV and CV), relative cavitation size (RCS = CS/TS), and relative cavitation volume (RCV=CV/TV). FPH emerged in 13 (2.6%) patients, with 12 (92.3%) of them being diagnosed ≤12 months of C-CRT. All FPHs were diagnosed in patients with TC (N=60): group-specific FPH incidence: 21.6%. TC (P<0.001) was the unique independent factor associated with higher FPH risk in multivariate analysis. Further analysis limited to TC patients exhibited the RCV>0.14 (37.5% versus 11.1% for RCV≤0.14; P<0.001), major RCS group [31.0% versus 19.0% for minor versus 0% for minimum RCS; P=0.008), and baseline hemoptysis (26.3% versus 13.6% for no hemoptysis; P=0.009) as the independent risk factors for higher FPH incidence. FPH was an infrequent (2.6%) complication of C-CRT in stage 3B/C SqCLC patients, but its incidence increased to 37.5% in patients presenting with TC and RCV>0.14. Diagnosis of >90% FPHs ≤12 months of C-CRT stresses the importance of close and careful follow-up of high-risk patients after C-CRT for multidisciplinary discussion of possible invasive preventive measures.

Abstract
OBJECTIVE To identify imaging markers predicting clinical outcomes to regorafenib in metastatic colorectal carcinoma (mCRC). METHODS The RadioCORRECT study is a post hoc analysis of a cohort of patients with mCRC treated within the phase III placebo-controlled CORRECT trial of regorafenib. Baseline and week 8 contrast-enhanced CT were used to assess response by RECIST 1.1, changes in the sum of target lesion diameters (ΔSTL), lung metastases cavitation and liver metastases density. Primary and secondary objectives were to develop ex novo univariable and multivariable models to predict overall survival (OS) and progression-free survival (PFS), respectively. RESULTS 202 patients were enrolled, 134 (66.3%) treated with regorafenib and 68 (33.7%) with placebo. In the univariate analysis, PFS predictors were lung metastases cavitation at baseline (HR 0.50, 95% CI 0.27 to 0.92, p=0.03) and at week 8 (HR 0.58, 95% CI 0.36 to 0.93, p=0.02). Baseline cavitation (HR 0.23, 95% CI 0.08 to 0.66, p=0.007), RECIST 1.1 (HR 0.23, 95% CI 0.14 to 0.4, p <0.0001) and ΔSTL (HR 1.16, 95% CI 1.06 to 1.27, p=0.002) predicted OS. We found an increase of 9% of diameter as the best threshold for discriminating OS (HR 2.64, 95% CI 1.61 to 4.34, p <0.001). In the multivariate analysis, baseline and week 8 cavitation remained significant PFS predictors. Baseline cavitation, RECIST 1.1 and ΔSTL remained predictors of OS in exploratory multivariable models. Assessment of liver metastases density did not predict clinical outcome. CONCLUSIONS RECIST 1.1 and ΔSTL predict favourable outcome to regorafenib. In contrast to liver metastases density that failed to be a predictor, lung metastases cavitation represents a novel radiological marker of favourable outcome that deserves consideration.

Shien K, Toyooka S. Role of surgery in N2 NSCLC: pros. Jpn J Clin Oncol 2016; 46:1168-1173. [PMID: 27655902 DOI: 10.1093/jjco/hyw125] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/30/2016] [Revised: 08/09/2016] [Accepted: 08/10/2016] [Indexed: 12/25/2022] Open
Abstract
The optimal management of clinical N2 Stage IIIA non-small cell lung cancer is still controversial. For a cure of locally advanced IIIA/N2 non-small cell lung cancer, the control of both local regions and possible distant micrometastases is crucial. Chemotherapy is generally expected to prevent distant recurrence. For local tumor control, radiotherapy or surgery has been adopted singly or in combination. If a complete resection can be safely performed, surgery remains the strongest modality for 'eradicating' local disease. Many retrospective studies have reported a possible survival benefit of induction treatment followed by surgery in selected patients with IIIA/N2 non-small cell lung cancer; however, randomized Phase III trials have failed to demonstrate the superiority of induction treatment followed by surgery over chemoradiotherapy, mainly because of the heterogeneity of the N2 status. IIIA/N2 non-small cell lung cancer consists of a heterogeneous group of disease ranging from microscopically single station to radiologically bulky ipsilateral multi-station mediastinal lymph node involvement. A recent definition proposed by the American College of Chest Physicians classified non-small cell lung cancer based on the N2 status, such as discrete or infiltrative type, and recommendations were made according to this N2 status, with definitive chemoradiotherapy recommended for infiltrative clinical N2 and definitive chemoradiotherapy or induction treatment followed by surgery recommended for other cases. Thus, the introduction of a multimodality treatment strategy seems to be necessary for the improved prognosis of non-small cell lung cancer patients with IIIA/N2 disease. In this review, we discuss the role of surgery and the optimal surgical management for patients with IIIA/N2 non-small cell lung cancer.

Abstract
Non-Small Cell Cancer (NSCLC) are frequently diagnosed at a later stage [1]. Treatment involves chemotherapy and radiation, either sequentially or concurrently [2]. Concurrent therapy is more efficacious but also associated with more complications [4–6]. We present a rare care of trachea-pulmonary fistula formation after concurrent chemo and radiation in a patient with Squamous Cell Cancer (SCC).

Abstract
Severe haemoptysis due to nonsmall cell lung cancer (NSCLC) is considered a grim condition, and there is still scarce data on its characteristics and outcome, despite new imaging and treatment modalities. This retrospective study sought to describe the clinical characteristics, pathophysiology and outcome of NSCLC-related haemoptysis. We included 125 consecutive patients with severe haemoptysis (>100 mL) at admission, 65 (52%) exhibiting squamous cell carcinoma. Tumour cavitation/necrosis was reported in 26 (21%) patients. 52 patients had received anticancer treatment, but none had received anti-angiogenic agents. Severe haemoptysis was related mainly to the bronchial artery (82%), and major pulmonary artery involvement was rare (6.4%). Interventional radiology was performed in 102 patients. Bleeding cessation was achieved in 108 (87%) out of 125 patients. The overall in-hospital and 1-year survival rates were 69% and 30%, respectively. Performance status (PS) ≥ 2 (OR 3.6, 95% CI 1.3-9.6), advanced stage (OR 8.6, 95% CI 2-37) and mechanical ventilation (OR 13, 95% CI 4.5-36) were independent predictors of in-hospital mortality. Performance status ≥ 2 (hazard ratio (HR) 2.4, 95% CI 1.5-3.7), advanced stage (HR 4, 95% CI 2.1-7.7), cancer progression (HR 2, 95% CI 1.01-2.7) and cavitation/necrosis (HR 1.7, 95% CI 1.21-3.2) were independently associated with 1-year mortality. Management of severe haemoptysis related to NSCLC should be improved, given our observed survival rates after hospital discharge.

Abstract
OBJECTIVES To investigate risk and predictors for radiation pneumonitis (RP) and tolerance of lung to radiation in patients treated with thoracic radiotherapy (RT) with or without surgery. METHODS AND MATERIALS A total of 433 consecutive patients with locally advanced non-small cell lung cancer were followed after three-dimensional conformal radiotherapy. Among them 284 received RT without surgical intervention and 149 received postoperative radiotherapy (PORT). RP was graded according to Common Terminology Criteria for Adverse Events version 4.0. RESULTS The rate of grade ≥ 2 and grade ≥ 3 RP was 50 and 16% in the PORT group compared with 38 and 9% in the non-surgical group (p < 0.05 for each comparison). The lung volume was significantly smaller in PORT group than in no-surgical group (3181 ± 915 cm(3) vs. 4010 ± 1120 cm(3), p<0.05). Age, chemotherapy, mean lung dose (MLD) and planning target volume (PTV) were predictors of RP for both non-surgical group and PORT group. Mean heart dose (MHD) predicted RP in PORT group only (OR = 1.28, p = 0.003). Among patients who developed RP, V20, MLD, and MHD were significantly lower in PORT group than in no-surgical group (p < 0.05 for each comparison). CONCLUSIONS Except MHD predicting RP in PORT group only, most of predictors for RP were consistent in patients treated with RT with or without surgery. Patients receiving PORT had a higher risk of RP than patients receiving RT without surgery did, possibly due to decreased lung volume and lower tolerance of lung to chemoradiotherapy.

Abstract
Local control for advanced non-small cell lung cancer (NSCLC) remains a significant problem with chemoradiation local failure rates in the chest of 30-50%. Despite attempts at dose escalation with conventional radiation therapy techniques, toxicities limit the amount of radiation that can be delivered. For stage I NSCLC, mounting evidence supports the use of hypofractionated radiation therapy (SBRT) to gain high local control rates with acceptable toxicity. For healthy patients with stage II/III NSCLC, the National Comprehensive Cancer Network guidelines suggest surgery is the preferred standard of care for patients with <N2 nodes or T3 tumors. In select patients who are surgical candidates or have more extensive disease, guidelines may include pre-operative chemoradiation followed by surgery, although this remains controversial and is the subject of a current national clinical trial (RTOG 0839). Dose escalation through conventional radiation therapy planning suggests that we can improve outcomes in stage III patients, but toxicity remains problematic. It follows that with improvements in imaging and delivery of radiotherapy, dose escalation with SBRT incorporation may improve local control in stage II/III NSCLC for medically inoperable patients. The rationale for dose escalation and some of the considerations for incorporation of SBRT dose escalation in stage III lung cancer are reviewed here.

Abstract
BACKGROUND Concurrent chemoradiation in stage III non-small cell lung cancer (NSCLC) patients with cavitary lesions is reported to cause serious lung complications and is a predictor of poor survival. However, the efficacy and toxicity associated with chemotherapy for advanced NSCLC patients with cavitary lesions is not clear. We investigated the toxicities, particularly hemoptysis and cavity infection, and efficacy associated with chemotherapy for NSCLC patients with cavitary lesions. METHODS We retrospectively reviewed consecutive patients who received first-line chemotherapy, including platinum-based chemotherapy, single-agent chemotherapy, or epidermal growth factor receptor-tyrosine kinase inhibitors, at our institution between January 2008 and December 2010. RESULTS We found tumor cavitation prior to treatment in 23 of 415 NSCLC patients (5.5%). The response rate of all the patients was 30%, and the median survival time (MST) was 8.9 months. The MST of the 15 patients treated with platinum-based chemotherapy was 11 months. Grade 1 bronchopulmonary hemorrhage occurred in 2 patients. Grade 3 cavitary infection occurred in 2 patients, resulting in the discontinuation of chemotherapy. CONCLUSIONS This study indicates that the toxicity of chemotherapy for NSCLC patients with cavitary lesions is tolerable; however, the development of cavitary infection should be carefully considered. In addition, this study suggests that the efficacy of chemotherapy for NSCLC patients with cavitary lesions is similar to the response rates reported in the literature; however, the survival of these patients may be worse than that for general NSCLC patients.

Abstract
Radiation is the foundation of treatment for locally advanced non-small cell lung cancer (NSCLC), and as such, optimal radiation dose is essential for successful treatment. This article will briefly review biological considerations of radiation dose and their effect in the context of three-dimensional conformal radiation therapy (3D-CRT) including intensity modulated radiation therapy (IMRT) and stereotactic body radiation therapy (SBRT) for NSCLC. It will focus on literature review and discussions regarding radiation dose effect in locally advanced NSCLC including potential severe and lethal toxicities of high dose radiation given with concurrent chemotherapy. Potential new approaches for delivering safe and effective doses by individualizing treatment based on functional imaging are being applied in studies such as the PET boost trial and RTOG1106. The RTOG concept of delivering high dose radiation to the more resistant tumors with the use of isotoxic dose prescription and adaptive planning will also be discussed in detail.

Abstract
Clinical significance of tumor cavitation (TC) prior to and following first-line chemotherapy of lung cancer is unclear. An evaluation of the incidence and prognostic role of TC among treatment naive lung cancer patients undergoing chemotherapy at a tertiary care institute in North India was undertaken. Retrospective data analysis and radiological review of newly diagnosed lung cancer patients initiated on chemotherapy over a 2-year period were carried out. Demographic characteristics and overall survival (OS) were compared between patients with and without TC at baseline. Patients who received 3 or more cycles of chemotherapy were included in analysis for response rates and new onset TC. Overall, 27 (7.8 %) of 347 patients had baseline TC. Among 271 non-small cell lung cancer (NSCLC) patients with (n = 26) and without (n = 245) baseline TC, histology was the only demographic characteristic that differed significantly [squamous 76.9 vs. 46.9 %; p = 0.004]. Majority (82.7 %) of NSCLC patients had advanced (stage IIIB/IV) disease. NSCLC patients with and without baseline TC alive at 6 months, 1 and 2 years were 34.6 versus 53.9 %, 11.5 versus 25.7 % and 3.8 versus 7.8 %, respectively. NSCLC patients with baseline TC had shorter median OS than those without (174 days [95 % confidence interval (CI) 106-242 days] vs. 235 days [95 % CI 207-263 days]). On multivariate Cox proportional hazard analysis, age [hazard ratio (HR) = 1.02, 95 % CI 1.01-1.04] and baseline TC [HR = 1.66, 95 % CI 1.03-2.69] were found significant. Response rates were similar between the two groups. Patients with TC after chemotherapy differed from those without in frequency of squamous histology (77.8 vs. 38.9 %; p < 0.001) and presence of metastatic disease (19.4 vs. 40.9 %; p = 0.016). Squamous histology has a significant association with presence of baseline TC and of new onset TC after chemotherapy. Presence of baseline TC has an independent association with shorter OS among NSCLC patients undergoing first-line chemotherapy.
