RESUMEN
Introduction: Immune checkpoint inhibitor (ICI)-based treatment has become standard treatment for patients with advanced NSCLC. We aimed to determine the survival benefit of upfront radiotherapy for brain metastases (BMs) in patients with NSCLC who received ICI alone (ICI-alone) or with chemotherapy (ICI-chemo). Methods: This study included consecutive patients with NSCLC having BMs who received ICI alone or ICI-chemo at 50 institutes between February 2017 and September 2021. The presence of BMs was confirmed by imaging before treatment. Treatment outcomes were compared between patients who did and did not receive upfront radiotherapy for BMs. Potential confounding factors were adjusted between the groups through inverse probability treatment weighting (IPTW) analysis and overlap weighting (OW) analysis with propensity scores. Results: Patients were grouped as ICI-alone cohort, 224 patients (upfront-radiotherapy group, 135 patients; no-radiotherapy group, 89 patients) and ICI-chemo cohort, 367 patients (upfront-radiotherapy group, 212 patients; no-radiotherapy group, 155 patients). In the ICI-alone cohort, the overall survival of the upfront-radiotherapy group was significantly longer than that of the no-radiotherapy group (IPTW-adjusted hazards ratio [HR] = 0.45 [95% confidence interval [CI]: 0.29-0.72], OW-adjusted HR = 0.52 [95% CI: 0.35-0.77]). In contrast, in the ICI-chemo cohort, the OS of the upfront-radiotherapy group was not significantly different from that of the no-radiotherapy group (IPTW-adjusted HR = 1.02 [95% CI: 0.70-1.48], OW-adjusted HR = 0.93 [95% CI: 0.65-1.33]). Conclusions: Upfront radiotherapy for BMs was associated with longer overall survival in patients with NSCLC who received ICI alone; however, it did not exhibit survival benefits in the patients who received ICI-chemo.
RESUMEN
Effective treatment for advanced lung cancer and idiopathic interstitial pneumonia (IIP) remains an unmet medical need. The relationship between chemotherapy's effectiveness in advanced lung cancer and the risk of acute exacerbation of IIP is poorly investigated. There is limited evidence that patients who experience an acute exacerbation of IIPs during cytotoxic chemotherapy have poorer outcomes than those who do not. Among 1004 patients with advanced lung cancer and IIPs enrolled in our published multi-centre retrospective study from 110 Japanese institutions, 708 patients (male: female, 645:63; mean age, 70.4) received first-line chemotherapy. The occurrence of chemotherapy-triggered acute exacerbations of IIPs and overall survival (OS) were analysed. The OS between groups of patients with and without the occurrence of acute exacerbation was compared at four landmark time points (30, 60, 90, and 120 days), starting from the first-line chemotherapy, using the landmark method. The incidence of acute exacerbation in patients who received first-line chemotherapy with small cell lung cancer (SCLC) and non-small cell lung cancer (NSCLC) was more frequent in NSCLC patients than in SCLC (4.2% vs 12.6%; odds ratio [OR]: 3.316; 95% confidence interval [CI] 1.25-8.8). Median survival time was 9.9 months (95% CI 9.2-10.7). Patients who experienced acute exacerbation had significant worse survival outcomes than those who did not at various time points (30 days, hazard ratio [HR]: 5.191, 95% CI 2.889-9.328; 60 days, HR: 2.351, 95% CI 1.104-5.009; 90 days, HR: 2.416, 95% CI 1.232-4.739; and 120 days, HR: 2.521, 95% CI 1.357-4.681). Acute exacerbation during first-line chemotherapy can predict poor survival.Trial Registration number: UMIN000018227.

OBJECTIVES: Osimertinib is a standard treatment for patients with EGFR-mutant non-small cell lung cancer (NSCLC) and is highly effective for brain metastases (BMs). However, it is unclear whether local treatment (LT) for BMs prior to osimertinib administration improves survival in EGFR-mutant NSCLC. We aimed to reveal the survival benefit of upfront local treatment (LT) for BMs in patients treated with osimertinib. MATERIALS AND METHODS: This multicenter retrospective study included consecutive patients with EGFR mutation (19del or L858R)-positive NSCLC who had BMs before osimertinib initiation between August 2018 and October 2021. We compared overall survival (OS) and central nervous system progression-free survival (CNS-PFS) between patients who received upfront LT for BMs (the upfront LT group), and patients who received osimertinib only (the osimertinib-alone group). Inverse-probability treatment weighting (IPTW) analysis was performed to adjust for potential confounding factors. RESULTS: Of the 121 patients analyzed, 57 and 64 patients had 19del and L858R, respectively. Forty-five and 76 patients were included in the upfront LT group and the osimertinib-alone groups, respectively. IPTW-adjusted Kaplan-Meier curves showed that the OS of the upfront LT group was significantly longer than that of the osimertinib-alone group (median, 95 % confidence intervals [95 %CI]: Not reached [NR], NR-NR vs. 31.2, 21.7-33.2; p = 0.021). The hazard ratio (HR) for OS and CNS-PFS was 0.37 (95 %CI, 0.16-0.87) and 0.36 (95 %CI, 0.15-0.87), respectively. CONCLUSIONS: The OS and CNS-PFS of patients who received upfront LT for BMs followed by osimertinib were significantly longer than those of patients who received osimertinib alone. Upfront LT for BMs may be beneficial in patients with EGFR-mutant NSCLC treated with osimertinib.

BACKGROUND: Everolimus, a mammalian target of rapamycin inhibitor used as an antineoplastic drug, is associated with a remarkably high incidence of interstitial lung disease (ILD). The clinical and pathological characteristics of ILD caused by everolimus have not been thoroughly investigated; therefore, we aimed to elucidate the features of everolimus-associated ILD. METHODS: We retrospectively reviewed the medical records of patients who received everolimus for cancer treatment at our hospital. Patient backgrounds were compared between the ILD and non-ILD groups. Chest computed tomography (CT), changes in biomarkers, and lung histopathological features were analyzed for ILD cases. RESULTS: Sixty-six patients were reviewed, and ILD developed in 19. There were no differences in patient demographics between the ILD and non-ILD groups. The severity of ILD was grade 1 (G1) in 9 and grade 2 (G2) in 10 cases. Chest CT showed organizing pneumonia (OP) or a hypersensitive pneumonia pattern. The levels of lactate dehydrogenase, C-reactive protein, Krebs von den lungen-6, and surfactant protein-D (SP-D) at the onset of ILD were significantly higher than those at baseline. Analysis of G1 and G2 ILD subgroups showed a higher SP-D levels in the G2 subgroup. Five patients underwent lung biopsies; all specimens demonstrated alveolitis with lymphocytic infiltration and granulomatous lesions, and some had OP findings. CONCLUSIONS: Everolimus-associated ILD is mild and has a favorable prognosis. Patients with symptomatic ILD were more likely to have higher SP-D levels than those with asymptomatic ILD. Granulomatous lesions are an important pathological feature of everolimus-associated ILD.

BACKGROUND: Idiopathic interstitial pneumonias are an independent risk factor of lung cancer, and a chemotherapy-induced acute exacerbation is the most common lethal complication in Japanese patients. The safety and efficacy of carboplatin and weekly paclitaxel for the treatment of non-small cell lung cancer with idiopathic interstitial pneumonias has been previously reported in prospective studies. However, carboplatin + paclitaxel with bevacizumab is currently the standard therapy. We conducted a multicenter, phase II study to confirm the safety and efficacy of carboplatin + weekly paclitaxel + bevacizumab for the treatment of patients with lung cancer complicated by idiopathic interstitial pneumonias. METHODS: Chemotherapy-naïve patients with advanced-stage or patients with post-operative recurrent non-squamous non-small cell lung cancer complicated by idiopathic interstitial pneumonias were enrolled. Patients received carboplatin (area under the curve: 5.0) and bevacizumab (15 mg/kg) on day 1 and paclitaxel (100 mg/m2) on days 1, 8, and 15 of each 4-week cycle. RESULTS: Seventeen patients less than the predetermined number were enrolled and received a median of four treatment cycles (range: 1-6). One patient (5.9%; 95% confidence interval: 0.1-28.7%) had acute exacerbation of interstitial pneumonia related to the study treatment which improved after corticosteroid treatment. The overall response rate was 52.9%. The median progression-free survival, median survival time, and 1-year survival were 5.7 months, 12.9 months, and 52.9%, respectively. CONCLUSION: The addition of bevacizumab to carboplatin and weekly paclitaxel might be safe and effective for the treatment of advanced non-small cell lung cancer complicated by idiopathic interstitial pneumonias.

PURPOSE: Vascular endothelial growth factor (VEGF) inhibitors are widely used in chemotherapy for non-small lung cancer (NSCLC). The purpose of the current study was to examine the impact of background cardiovascular risk factors on VEGF inhibitor-related adverse vascular events (VEGF-related AVEs) in patients with NSCLC who also had comorbidities. METHODS: We conducted a retrospective study of 118 NSCLC patients treated with bevacizumab or ramucirumab from April 2010 to December 2022. We compared baseline cardiovascular risk factors with VEGF-related AVEs. RESULTS: VEGF-related AVEs and discontinuation due to VEGF-related AVEs were reported in 54 patients and 21 patients, respectively. VEGF-related AVEs were significantly more common with male sex, smoking history, history of hypertension, dyslipidemia, diabetes mellitus, or cardiovascular disease. Discontinuation due to VEGF-related AVEs was significantly more common in patients with history of hypertension or chronic kidney disease. VEGF-related AVEs were significantly more common in patients with ≥ 3 cardiovascular risk factors than patients with < 3. Discontinuation due to VEGF-related AVEs was significantly more common in patients with ≥ 4 cardiovascular risk factors than patients with < 4. Multivariate analysis demonstrated that male sex, hypertension, and ≥ 6 cycles of VEGF inhibitors were each associated with VEGF-related AVEs and hypertension was associated with discontinuation due to VEGF-related AVEs. CONCLUSION: Our study demonstrated that history of hypertension was independently associated with increased risk of both VEGF-related AVEs and discontinuation due to VEGF-related AVEs. In conclusion, we need to be aware of VEGF-related AVEs when using VEGF inhibitors for patients with ≥ 3 cardiovascular risk factors.

BACKGROUND: Nab-paclitaxel (nab-PTX) has better transfer to tumor tissue than cremophor-based paclitaxel. It suggests that the optimum dose of nab-PTX might be lower than the dose and schedule that is widely used. We designed a randomized phase II trial to examine the clinical utility and safety of nab-PTX in patients with previously treated advanced non-small cell lung cancer (NSCLC). METHODS: Patients were randomly allocated (1:1) to receive nab-PTX monotherapy at 100 mg/m2 (group A) or 70 mg/m2 (group B). The primary endpoint was progression-free survival (PFS). Secondary endpoints included overall survival (OS), objective response rate (ORR), and adverse events (AEs). RESULTS: Finally, 81 patients were randomized. Similar results were observed in both groups for PFS (3.75 vs. 3.71 months), OS (13.50 vs. 16.13 months), or ORR (20.5% vs. 23.1%). The incidences of grade 3 or worse AEs were 57.5% in group A and 41.5% in group B. The proportion of serious side effects was 10.0% in group A and 4.9% in group B. CONCLUSION: Both standard dose and low dose of nab-PTX monotherapy are active for previously treated NSCLC patients with better safety profile. Therefore, nab-PTX 70 mg/m2 dose and schedule in the trial would be a reasonable option.

BACKGROUND: The clinical questions of whether chemotherapy as initial treatment, compared with best supportive care (BSC), improves overall survival (OS) and whether it increases the occurrence risk of acute exacerbation of idiopathic interstitial pneumonia (IIP) in patients with advanced-stage lung cancer and IIP remain inconclusive. This study addresses these issues, given that chemotherapy-related acute exacerbation of IIP may be a direct cause of mortality in these patients. METHODS: We enrolled 1003 patients from 110 Japanese institutions and collected clinical profiles from 707 and 296 patients in the chemotherapy (men: women, 645:62; mean age, 70.4 ± 6.9 years) and BSC (men: women, 261:35; mean age, 75.2 ± 7.8) groups, respectively. We used propensity score matching to create 222 matched pairs from both groups using patient demographic data (age, sex, smoking status, performance status, history of acute exacerbation of IIP, desaturation on exertion, clinical diagnosis of IIP, high-resolution computed tomography findings, serum fibrotic markers, pulmonary function status, and lung cancer histopathology). Logistic or Cox regression analyses were performed using matched data to assess the effects of chemotherapy on the risk of acute exacerbation of IIP or OS, respectively. RESULTS: In the well-matched cohort, chemotherapy improved OS (hazard ratio: 0.629, 95% confidence interval [CI]: 0.506-0.783, p < 0.0001); however, it involved significant acute exacerbation of IIP (odds ratio: 1.787, 95% CI: 1.026-3.113) compared to BSC. CONCLUSIONS: Compared with BSC, chemotherapy can improve OS in patients with advanced-stage lung cancer and IIP; however, it increases the risk of acute exacerbation of IIP.

INTRODUCTION: Malignant tumors are the major cause of death in hemodialysis patients. Management of these patients remains challenging as there is no evidence that chemotherapy is beneficial, and a lack of information about actual clinical practice. METHODS: This multicenter retrospective study included hemodialysis patients who were diagnosed with lung cancer from January 2002 to June 2018. We reviewed their clinical information including patient characteristics associated with lung cancer and end-stage renal disease, regimen, efficacy and safety of chemotherapy, and outcomes. RESULTS: A total of 162 patients from 22 institutions in Japan were registered. Of 158 eligible patients, 91 received chemotherapy (80 as palliative chemotherapy and 11 as chemoradiotherapy) and 67 received best supportive care only regardless of cancer stage. In small cell lung cancer (SCLC) and non-small cell lung cancer (NSCLC) patients who received cytotoxic chemotherapy, the objective response rates (ORR) and median overall survival (OS) were 68.1 %, 12.3 months and 37.0 %, 8.5 months, respectively. The ORR and median OS in patients with EGFR-mutant NSCLC treated with EGFR-tyrosine kinase inhibitors (TKI) were 44.4 % and 38.6 months. The treatment-related adverse events (Grade 3 or higher) induced by cytotoxic chemotherapy were myelosuppression and febrile neutropenia; treatment-related death (TRD) was observed in one patient. TRD occurred in 3 of 18 patients who received EGFR-TKI. CONCLUSION: Chemotherapy should be considered for hemodialysis patients with EGFR-mutant NSCLC and SCLC. However, the survival benefits of chemotherapy for NSCLC patients with EGFR-wild type are unclear; physicians should carefully consider whether to offer chemotherapy to this patient subset.

BACKGROUND: Idiopathic pulmonary fibrosis (IPF) is a fatal lung disease implicated as an independent risk factor for lung cancer. However, optimal treatment for advanced lung cancer with IPF remains to be established. We performed a randomised phase 3 trial (J-SONIC) to assess the efficacy and safety of nintedanib plus chemotherapy (experimental arm) compared with chemotherapy alone (standard-of-care arm) for advanced nonsmall cell lung cancer (NSCLC) with IPF. METHODS: Chemotherapy-naïve advanced NSCLC patients with IPF were allocated to receive carboplatin (area under the curve of 6 on day 1) plus nanoparticle albumin-bound paclitaxel (nab-paclitaxel) (100â mg·m-2 on days 1, 8 and 15) every 3â weeks with or without nintedanib (150â mg twice daily, daily). The primary end-point was exacerbation-free survival (EFS). RESULTS: Between May 2017 and February 2020, 243 patients were enrolled. Median EFS was 14.6â months in the nintedanib plus chemotherapy group and 11.8â months in the chemotherapy group (hazard ratio (HR) 0.89, 90% CI 0.67-1.17; p=0.24), whereas median progression-free survival was 6.2 and 5.5â months, respectively (HR 0.68, 95% CI 0.50-0.92). Overall survival was improved by nintedanib in patients with nonsquamous histology (HR 0.61, 95% CI 0.40-0.93) and in those at GAP (gender-age-physiology) stage I (HR 0.61, 95% CI 0.38-0.98). Seven (2.9%) out of 240 patients experienced acute exacerbation during study treatment. CONCLUSIONS: The primary end-point of the study was not met. However, carboplatin plus nab-paclitaxel was found to be effective and tolerable in advanced NSCLC patients with IPF. Moreover, nintedanib in combination with such chemotherapy improved overall survival in patients with nonsquamous histology.

Thymic carcinoma is a relatively rare type of malignant tumor. The present retrospective study evaluated the efficacy and safety of carboplatin plus nanoparticle albumin-bound paclitaxel for the treatment of advanced thymic carcinoma. The study included data from 12 patients with advanced thymic carcinoma treated in the Nippon Medical School Hospital (Tokyo, Japan). Response to treatment, patient survival and treatment safety were assessed. The objective response rate was 66.7% (8/12 patients). Disease control was achieved in 11 patients (91.7%). At the median follow-up time of 27.6 months (range, 6.2-75.1 months), the median progression-free survival and median first-line overall survival times were 16.7 months [95% confidence interval (CI), 13.2-37.7] and 14.3 months (95% CI, 4.7-54.6), respectively. There was no occurrence of febrile neutropenia or treatment-related death. The results of the present study showed that carboplatin plus nanoparticle albumin-bound paclitaxel was effective and safe. Therefore, it is a promising chemotherapy regimen for the treatment of advanced thymic carcinoma.
RESUMEN
Antibody-drug conjugate (ADC) was novel type of anticancer drugs. Trastuzumab deruxtecan (T-DXd), a human epidermal growth factor receptor 2 (HER2) targeting ADC, can be a novel treatment option for HER2 alternation (mutation, expression, amplification) advanced-stage non-small-cell lung cancer (NSCLC) from DESTINY-Lung01 result. Herein, we report a successful treatment with T-DXd for NSCLC harboring HER2 exon 20 insertion mutation in a patient with poor performance status (PS). We presented a case of a 52-year-old heavily pretreated female patient diagnosed with lung adenocarcinoma (cT1bN3M0, stage IIIB). After fifth-line pretreatment of systemic chemotherapy, primary tumor recurrence, pleural effusion, and miliary lung metastases were observed. The patient presented with hypoxia requiring oxygen therapy via nasal cannula at a flow rate of 4 L per minute, cancer pain, and cachexia requiring opioid treatment. Her Eastern Cooperative Oncology Group PS score was assessed 3. Comprehensive genomic profiling revealed HER2 exon 20 insertion mutation. After treatment with T-DXd was approved by the ethical review committee of Nippon Medical School Hospital, treatment was started. The tumor size decreased significantly, and her PS score decreased from 3 to 1, with improvement of hypoxia, cancer pain, and cachexia. The patient is still receiving treatment, without disease progression 6 months after starting treatment with T-DXd. Despite cases of poor PS, NGS should be performed and target therapy including ADCs should be considered.
RESUMEN
INTRODUCTION: To investigate the genomic profiles of patients with lung cancer with idiopathic pulmonary fibrosis (IPF-LC), mechanism of carcinogenesis, and potential therapeutic targets. METHODS: We analyzed 29 matched, surgically resected, cancerous and noncancerous lung tissues (19 IPF-LC and 10 non-IPF-LC) by whole-exome sequencing and bioinformatics analysis and established a medical-engineering collaboration with the Department of Engineering of the Tokyo University of Science. RESULTS: In IPF-LC, CADM1 and SPC25 were mutated at a frequency of 47% (9 of 19) and 53% (10 of 19), respectively. Approximately one-third of the IPF-LC cases (7 of 19; 36%) had both mutations. Pathway analysis revealed that these two genes are involved in transforming growth factor-ß1 signaling. CADM1 and SPC25 gene mutations decreased the expression of CADM1 and increased that of SPC25 revealing transforming growth factor-ß1-induced epithelial-to-mesenchymal transition and cell proliferation in lung cancer cells. Furthermore, treatment with paclitaxel and DNMT1 inhibitor suppressed SPC25 expression. CONCLUSIONS: CADM1 and SPC25 gene mutations may be novel diagnostic markers and therapeutic targets for IPF-LC.
RESUMEN
BACKGROUND/AIM: Pulmonary pleomorphic carcinoma (PPC) is a rare and aggressive tumor that is resistant to treatment. The expression and prognostic value of programmed cell death-ligand 1 (PD-L1) and its association with epithelial-mesenchymal transition (EMT) in PPC remains unclear. PATIENTS AND METHODS: The expression of PD-L1 and EMT markers, such as E-cadherin, vimentin, zinc finger E-box-binding homeobox 1 (ZEB-1), and cellular mesenchymal-epithelial transition (c-Met) was evaluated by immuno - histochemistry in 16 patients with PPC who underwent surgical resection. RESULTS: The expression of PD-L1 varied between carcinomatous and sarcomatous areas. Positive correlations between PD-L1 and vimentin expression in carcinomatous areas (r=0.668, p=0.005) and PD-L1 and ZEB-1 expression in sarcomatous areas (r=0.562, p=0.023) were found. High PD-L1 and ZEB-1 expression in sarcomatous areas predicted poor survival (p=0.045 and p=0.012, respectively). CONCLUSION: PD-L1 expression associated with ZEB1 expression in the sarcomatoid component of patients with PPC may be useful for predicting patient prognosis.

BACKGROUND: Lung cancer is most common among older individuals. However, polypharmacy and comorbidities, which are also more common in older individuals, can limit treatment options. Previous studies suggest that afatinib can be used safely and effectively in elderly patients. This study investigated the anti-tumour activity and safety profile of first-line afatinib in previously-untreated elderly Japanese patients with EGFR mutation-positive non-small cell lung cancer (NSCLC). METHODS: This was a single-arm, open-label, phase II study, performed in multiple centres in Japan. Previously untreated patients, aged ≥75 years, with EGFR mutation-positive (Del19 or L858R) advanced NSCLC were treated with afatinib 40 mg until disease progression or unacceptable toxicity. Adverse events (AEs) were managed with protocol-defined dose adjustments. The primary endpoint was objective response rate (ORR) by central review. RESULTS: In total, 38 patients received at least one dose of afatinib, and 37 were evaluable for response. Median age was 77.5 years (range 75-91), all patients had an Eastern Cooperative Oncology Group performance status of 0 or 1, and 60.5% had Del19-positive disease. Median follow-up was 838 days. ORR was 75.7% (2 complete responses and 26 partial responses). Median progression-free survival was 14.2 months (95% confidence interval [CI], 9.5-19.0). Median overall survival (OS) was 35.2 months (95% CI, 35.2-not reached); the 2-year OS rate was 78.3%. The most common grade 3/4 treatment-related AEs (TRAEs) were diarrhoea (28.9%), paronychia (23.7%), and rash/acne (15.8%). Dose reductions due to TRAEs were reported in 78.9% of patients, and eight (21.1%) patients discontinued afatinib due to TRAEs. No treatment-related deaths were reported. CONCLUSION: Although dose adjustments were relatively common in this small group of Japanese patients aged ≥75 years with EGFR mutation-positive NSCLC, discontinuation occurred much less frequently, and most patients were able to stay on treatment for well over a year. Further, afatinib was associated with high response rates and prolonged PFS and OS.

BACKGROUND: Patient participation in decisions related to their treatment is strongly recommended. This study was conducted to develop and evaluate a support tool that can help patients make decisions related to their own treatment. METHODS: Twenty cancer patients who were hospitalized for first-line treatment were enrolled. Before hospitalization, a 'Check sheet on treatment selection', which contained 14 questions, was distributed to patients and/or their families. After hospitalization, the attending physician explained the treatment while referring to the written check sheet. At discharge, patients' responses to the 'Questionnaire on check sheet and treatment selection' were collected to evaluate the utility of the check sheet. Finally, the 'Questionnaire of the check sheet' was handed to the attending physician to evaluate. RESULTS: Of the fourteen patients who responded to the questionnaire, all indicated that the check sheets were helpful for decision-making and that using the sheets empowered them to ask their doctors questions. Only one person felt uncomfortable with compiling the check sheet. Physicians stated that the check sheet facilitated patient decision-making and improved communication with patients. However, some felt that this activity increased the administrative burden of medical professionals. CONCLUSION: Almost all patients stated that the present check sheet was useful as a decision support tool and facilitated communication between doctors and patients. Before incorporation into general clinical practice, this increased benefit should be weighed against the potential extra administrative workload imposed on clinicians.

Osimertinib is the standard treatment for epidermal growth factor receptor (EGFR)-mutant non-small-cell lung cancer. However, drug-induced interstitial lung disease (ILD) is recognized as a serious adverse event associated with EGFR-tyrosine kinase inhibitors (TKIs). We herein report a 78-year-old woman with stage IV lung adenocarcinoma harboring an EGFR L858R mutation on exon 21 who received rechallenge treatment with afatinib after osimertinib-induced ILD with an organizing pneumonia pattern. This is the first report of successful rechallenge with afatinib after osimertinib-induced ILD. Treatment with other EGFR-TKIs after osimertinib-induced ILD may be an option for subsequent therapy.

BACKGROUND: Chemotherapy-induced acute exacerbation (AEx) of idiopathic interstitial pneumonias (IIPs) seriously compromises the success of treatment of Japanese lung cancer patients. Here, we conducted a nationwide surveillance to clarify the risk of AEx and compare it with the survival benefit of chemotherapy for this population. METHODS: Advanced nonsmall cell lung cancer (NSCLC) or small cell lung cancer (SCLC) patients with IIPs were retrospectively analysed. For the surveillance of first-line chemotherapy in 2009, we gathered clinical data from 396 patients who received chemotherapy at 19 institutions between January 1990 and July 2009. In a consecutive retrospective study in 2012, we analysed data from 278 patients from 17 institutions who received second-line chemotherapy between April 2002 and March 2012. RESULTS: Of the 396 patients analysed, 13.1% developed chemotherapy-related AEx. Combination chemotherapies of carboplatin plus paclitaxel (CP) or carboplatin plus etoposide (CE) were frequently used as first-line treatments. The lowest incidence of AEx was 3.7% in CE, followed by 8.6% in CP. In the retrospective study, 16.2% of the 278 patients developed a second-line chemotherapy-related AEx. The overall response rate by second-line chemotherapy was 7.4% in NSCLC and 25.7% in SCLC. The median overall survival from second-line and first-line chemotherapy was 8.0 and 14.3â months in NSCLC, and 8.7 and 16.0â months in SCLC, respectively. CONCLUSION: Combination chemotherapies consisting of CP or CE are candidates for standard first-line treatments for patients with advanced lung cancer accompanied by IIP. Second-line chemotherapy should be considered for patients remaining fit enough to receive it.
RESUMEN
BACKGROUND: Interstitial lung disease (ILD) induced by immune checkpoint inhibitors (ICIs) is a potentially life-threatening adverse event. The purpose of this study was to evaluate whether the development of immune-related adverse events (irAEs), especially ILD, was associated with treatment efficacy and to research the features and risk factors of ILD in advanced non-small cell lung cancer (NSCLC). METHODS: Between December 2015 and November 2018, 130 advanced NSCLC patients were treated with nivolumab, pembrolizumab or atezolizumab. The patients were categorized into two groups (irAEs group or non-irAEs group). Subsequently, we divided the irAEs group into two groups based on the incidence of ILD (ILD group and irAEs-non-ILD group). Treatment efficacy and the characteristics of ILD were evaluated. RESULTS: A total of 39 (30%) patients developed irAEs. ILD was observed in 16 (12%) patients. Patients with ILD had a higher objective response rate (ORR) compared with irAEs-non-ILD patients and non-irAEs patients (63%, 43% and 22%, respectively). Median progression-free survival (mPFS) was 15.9 months in ILD patients, 5.4 months in irAEs-non-ILD patients and 3.3 months in non-irAEs patients (log-rank test, P = 0.033). Pre-existing interstitial pneumonia (IP) was an independent risk factor for ILD-induced ICIs (odds ratio [OR] 14.7; 95% confidence interval [CI]: 2.16-99.6, P = 0.006). CONCLUSIONS: ORR and PFS were significantly better in ILD patients than in irAEs-non-ILD and non-irAEs patients. Pre-existing history of IP was an independent risk factor for ILD-induced ICIs.

Dramatic progress in targeted therapy and immunotherapy has been changing clinical practices in lung cancer. With the accumulation of clinical practice, it has become clear that pre-existing interstitial pneumonia (IP) could be a risk factor for drug-induced lung injury, which has enhanced awareness regarding the difficulty in treating lung cancer with comorbid IP. Unfortunately, there is only low-grade evidence in the field of lung cancer with comorbid IP, because almost all clinical trials exclude such patients. There have been very few specialized clinical trials for patients with lung cancer and underlying IPs thus far. Therefore, it is necessary to treat such cases empirically or to give up on the treatment itself. Considering these circumstances, establishing how to treat lung cancer with comorbid IP is an urgent issue. This paper is a summary of the official statement reported by the Diffuse Lung Disease/Thoracic Oncology Assembly and the Japanese Respiratory Society (JRS) in 2017, which attempts to approach lung cancer with comorbid IP systematically.
