Epidermal growth factor receptor (EGFR) is the most frequently mutated driver oncogene in non-smoking-related, non-small-cell lung cancer (NSCLC). EGFR-mutant NSCLC has a non-inflamed tumor microenvironment (TME), with low infiltration by CD8+ T cells and, thus, immune checkpoint inhibitors, such as anti-programmed cell death-1 (anti-PD-1) have weak anti-tumor effects. Here, we showed that CD8+ T-cell responses were induced by an EGFR-tyrosine kinase inhibitor (TKI) in syngeneic Egfr-mutant NSCLC tumors, which was further pronounced by sequential dual blockade of PD-1 and vascular endothelial growth factor receptor 2 (VEGFR2). However, simultaneous triple blockade had no such effect. PD-1/VEGFR2 dual blockade did not exert tumor-inhibitory effects without pre-treatment with the EGFR-TKI, suggesting that treatment schedule is crucial for efficacy of the dual blockade therapy. Pre-treatment with EGFR-TKI increased the CD8+ T-cell/regulatory T-cell (Treg) ratio, while also increasing expression of immunosuppressive chemokines and chemokine receptors, as well as increasing the number of M2-like macrophages, in the TME. Discontinuing EGFR-TKI treatment reversed the transient increase of immunosuppressive factors in the TME. The subsequent PD-1/VEGFR2 inhibition maintained increased numbers of infiltrating CD8+ T cells and CD11c+ dendritic cells. Depletion of CD8+ T cells in vivo abolished tumor growth inhibition by EGFR-TKI alone and the sequential triple therapy, suggesting that EGFR inhibition is a prerequisite for the induction of CD8+ T-cell responses. Our findings could aid in developing an alternative immunotherapy strategy in patients with cancers that have driver mutations and a non-inflamed TME.

PURPOSE: Osimertinib is still essential for the treatment of epidermal growth factor receptor (EGFR)-T790M-positive non-small-cell lung cancer (NSCLC) even in a relapsed setting, which suggests the importance of rebiopsy. The clinical value of repeat rebiopsy in patients with NSCLC who are T790M-negative on a first rebiopsy remains unclear. In this study, we examined the status of the first rebiopsy and evaluated the frequency of repeat rebiopsy of T790M-negative tumors detected by the first rebiopsy. METHODS: We reviewed 144 patients with NSCLC with major EGFR mutations, but not T790M, who received first- or second-generation EGFR tyrosine kinase inhibitors (TKIs), registered in the prospective, umbrella-type lung cancer patient registry (CS-Lung-003). RESULTS: Overall, 63 patients (44%) underwent the first rebiopsy. In the first rebiopsy, 51 (81%) and 12 (19%) of 63 underwent histological/cytological rebiopsy and liquid biopsy with the blood sampling, respectively. In the repeat rebiopsy, 23 (85%) and 4 (15%) of 27 underwent histological/cytological rebiopsy and liquid biopsy, respectively. The most frequently rebiopsied site was a pulmonary lesion (n = 24, 38.7%). Overall, 29 (46.0%) of 63 patients harbored the T790M mutation. Interestingly, a high detection rate of cancer cells did not necessarily indicate a high detection rate of the T790M mutation (p < 0.01). Among 34 patients with T790M-negative tumors confirmed on the first rebiopsy, 20 (58.8%) underwent repeat rebiopsies following interval therapy, revealing that seven (36.8%) had T790M-positive tumors. Osimertinib yielded median progression-free survival of 11.8 and 16.2 months in patients with the 790M mutation detected by the first rebiopsy and repeat rebiopsy, respectively. CONCLUSION: In our prospective cohort, the T790M mutation was detected in 46% of patients who underwent the first rebiopsy. Repeat rebiopsy may increase the ability to detect the T790M mutation positivity rate.

BACKGROUND: Tyrosine kinase activation plays an important role in the progression of pulmonary fibrosis. In this study, we analyzed the expression of 612 kinase-coding and cancer-related genes using next-generation sequencing to identify potential therapeutic targets for idiopathic pulmonary fibrosis (IPF). METHODS: Thirteen samples from five patients with IPF (Cases 1-5) and eight samples from four patients without IPF (control) were included in this study. Six of the thirteen samples were obtained from different lung segments of a single patient who underwent bilateral pneumonectomy. Gene expression analysis of IPF lung tissue samples (n = 13) and control samples (n = 8) was performed using SureSelect RNA Human Kinome Kit. The expression of the selected genes was further confirmed at the protein level by immunohistochemistry (IHC). RESULTS: Gene expression analysis revealed a correlation between the gene expression signatures and the degree of fibrosis, as assessed by Ashcroft score. In addition, the expression analysis indicated a stronger heterogeneity among the IPF lung samples than among the control lung samples. In the integrated analysis of the 21 samples, DCLK1 and STK33 were found to be upregulated in IPF lung samples compared to control lung samples. However, the top most upregulated genes were distinct in individual cases. DCLK1, PDK4, and ERBB4 were upregulated in IPF case 1, whereas STK33, PIM2, and SYK were upregulated in IPF case 2. IHC revealed that these proteins were expressed in the epithelial layer of the fibrotic lesions. CONCLUSIONS: We performed a comprehensive kinase expression analysis to explore the potential therapeutic targets for IPF. We found that DCLK1 and STK33 may serve as potential candidate targets for molecular targeted therapy of IPF. In addition, PDK4, ERBB4, PIM2, and SYK might also serve as personalized therapeutic targets of IPF. Additional large-scale studies are warranted to develop personalized therapies for patients with IPF.

A 76-year-old woman who was treated with lorlatinib for postoperative recurrent anaplastic lymphoma kinase-positive lung adenocarcinoma visited our hospital with massive hemoptysis. Chest computed tomography showed massive bleeding from the right upper lobe; however, the cause of bleeding was unclear. After bronchial artery embolization (BAE), bronchial occlusion was performed using an Endobronchial Watanabe Spigot (EWS) that was easily placed because BAE had reduced the bleeding volume. Treatment with BAE alone was inadequate; however, additional therapy with EWS after BAE successfully controlled the massive hemoptysis, especially in this patient who underwent lobectomy to prevent respiratory dysfunction.

Tepotinib, the novel MET-tyrosine kinase inhibitor, shows an antitumor effect for patients with non-small-cell lung cancer (NSCLC) harboring MET exon 14 skipping mutation. In January 2022, the AmoyDx® Pan Lung Cancer polymerase chain reaction Panel (AmoyDx® panel), which had a shorter turnaround time than the conventional test, was launched in Japan as a tepotinib companion test. We report a patient with an advanced MET-mutant NSCLC promptly diagnosed using the AmoyDx® panel and successfully treated with tepotinib. Although the patient's performance status (PS) worsened due to the rapid tumor progression and lung abscess formation, the tumor shrank immediately after tepotinib treatment with marked PS improvement.

記述言語：英語

Dasatinib, an effective second-generation tyrosine kinase inhibitor, is used to treat breakpoint cluster region-Ableson-positive chronic myeloid leukemia or Philadelphia chromosome-positive acute lymphocytic leukemia. One common adverse event associated with dasatinib use is fluid retention, including pleural effusion. Chylothorax, however, is a rare adverse event. Although the precise mechanism of dasatinib-induced chylothorax is unclear, almost all cases involve right or bilateral chylothorax, and mostly occur within 5 years of dasatinib initiation. Here, we report a rare case of a patient with dasatinib-induced massive left chylothorax 10 years after dasatinib initiation, which improved after dasatinib termination and a switch to bosutinib.

Primary salivary gland-type tumors of the lung are rare, accounting for &lt
1% of all lung tumors. There are few reports on chemotherapy for the treatment of primary salivary gland-type tumors of the lung. The patient in this report was a 71-year-old woman who presented with a chief complaint of dysphagia. Upper gastrointestinal endoscopy revealed an esophageal stricture, but biopsy showed no malignancy. Chest computed tomography (CT) showed carcinomatous lymphangiomatosis and a nodule in the right lung. Bronchoscopy showed a rough mucous membrane of the central bronchi, while biopsy showed adenocarcinoma. The patient was diagnosed with bronchogenic adenocarcinoma and received carboplatin, pemetrexed, and pembrolizumab, which alleviated the esophageal stricture and cancerous lymphangiopathy. However, the adenocarcinoma progressed, and she subsequently received several rounds of chemotherapy. One year after diagnosis, the patient died, and pathological autopsy revealed primary salivary gland-type tumors of the lung.

Osimertinib, a third generation epidermal growth factor receptor (EGFR) tyrosine kinase inhibitor, is the standard treatment for patients with lung cancer harboring EGFR T790M; however, acquired resistance is inevitable due to genetic and epigenetic changes in cancer cells. In addition, a recent randomized clinical trial revealed that the combination of osimertinib and bevacizumab failed to exhibit superior progression-free survival compared with osimertinib alone. The present study aimed to investigate the effect of triple therapy with osimertinib, bevacizumab and cetuximab in xenograft tumors with different initial tumor volumes (conventional model, 200 mm3 and large model, 500 mm3). The results demonstrated that osimertinib significantly inhibited tumor growth in both the conventional and large models; however, maximum tumor regression was attenuated in the large model in which hypoxia-inducible factor-1α (HIF-1α) and transforming growth factor-α (TGF-α) expression levels increased. Although the combination of osimertinib and bevacizumab exerted a greater inhibitory effect on tumor growth compared with osimertinib in the conventional model, the effect of this combination therapy was attenuated in the large model. TGF-α attenuated sensitivity to osimertinib in vitro; however, this negative effect was counteracted by the combination of osimertinib and cetuximab, but not osimertinib and bevacizumab. In the large xenograft tumor model, the triple therapy induced the greatest inhibitory effect on tumor growth compared with osimertinib alone and its combination with bevacizumab. Clinical trials of the triple therapy are required for patients with lung cancer with EGFR mutations and HIF-1α/TGF-α.

Pembrolizumab is a monoclonal antibody with anti-tumor effects. Only a few reports have previously described retrobulbar optic neuritis induced by pembrolizumab. We herein report the case of a 64 -year-old man with advanced lung adenocarcinoma who received cisplatin, pemetrexed, and pembrolizumab combination therapy for six months. Following treatment, a visual field test showed a left central scotoma. Imaging studies showed left optic neuritis without brain metastasis. Blood tests showed an elevated serum creatinine level. He was diagnosed with retrobulbar optic neuritis and pembrolizumab-induced renal failure. After receiving corticosteroid treatment, his renal function rapidly improved. The optic neuritis improved somewhat, but it was not adequately resolved.

Heerfordt's syndrome is a rare subtype of sarcoidosis and features a combination of facial palsy, parotid swelling, and uveitis, associated with a low-grade fever. Cases with two of three symptoms are called "incomplete Heerfordt's syndrome." Heerfordt's syndrome involving other cranial nerve symptoms is relatively rare. We herein report a case of incomplete Heerfordt's syndrome presenting with trigeminal nerve palsy and a reversed halo sign, a rare manifestation of pulmonary sarcoidosis. The histological diagnosis following a biopsy of the parotid gland and endobronchial ultrasound-guided trans-bronchial needle aspiration of the mediastinal lymph nodes was sarcoidosis. The symptoms and lung lesions improved after corticosteroid therapy.

Epidermal growth factor receptor (EGFR)-tyrosine kinase inhibitors (TKIs) are key drugs in the treatment of non-small cell lung cancer (NSCLC) patients with EGFR mutations; however, first-generation EGFR-TKIs, such as gefitinib and erlotinib, are not effective in patients with uncommon EGFR mutations. In contrast, efficacy of afatinib has been reported in some types of uncommon EGFR mutation such as G710X, L861Q. The effect of afatinib in NSCLC patients with the EGFR K860I mutation has been shown in vitro, but its clinical efficacy has not been demonstrated. Here, we report the experience of afatinib administration in an NSCLC patient with an EGFR K860I mutation. A 69-year-old woman presented with right hemiplegia and dysarthria. Multiple brain and lung tumors were observed. She underwent craniotomy and was diagnosed with lung adenocarcinoma. After stereotactic brain radiation therapy, cisplatin, pemetrexed, and bevacizumab combination therapy was initiated. Unfortunately, she was unable to continue chemotherapy as she had an intestinal perforation after two cycles. After five months, recurrence of multiple brain metastases and an increase in primary lung cancer were confirmed. Next-generation sequencing (NGS) was performed in a clinical trial, and an EGFR K860I mutation was detected in her tumor. Afatinib was administered and the primary lung tumor shrank, but multiple brain metastases were exacerbated. After irradiation of the brain, afatinib administration was continued. In conclusion, afatinib may show an effect in NSCLC patients with the EGFR K860I mutation, but its efficacy is limited.

OBJECTIVE: A third-generation epidermal growth factor receptor (EGFR) tyrosine kinase inhibitor (TKI), osimertinib, is the standard treatment for patients with non-small cell lung cancer harbouring mutant EGFR. Unfortunately, these patients inevitably acquire resistance to EGFR-TKI therapies, including osimertinib. However, the mechanism associated with this resistance remains unclear. METHODS: A 63-year-old Japanese female with lung adenocarcinoma underwent right upper lobectomy (pT1bN2M0 pStage IIIA, EGFR Ex21 L858R). She manifested post-operative tumour recurrence with multiple lung metastases 8 months later and began gefitinib treatment. The lung lesions re-grew 15 months later, and EGFR T790M mutation was detected in the lung metastasis re-biopsy. She was administered osimertinib; however, it relapsed with pleural effusion 16 months later. We isolated cells from the osimertinib-resistant pleural effusion to establish a novel cell line, ABC-31. RESULTS: Although the EGFR L858R mutation was detected in ABC-31 cells, the T790M mutation was lost. ABC-31 cells were resistant to EGFR-TKIs, including osimertinib. Phospho-receptor tyrosine kinase array revealed activation of the insulin-like growth factor 1 receptor (IGF1R), whereas overexpression of the IGF1R ligand, IGF2, induced IGF1R activation in ABC-31 cells. Combination therapy using EGFR-TKIs and IGF1R inhibitor acted synergistically in vitro. She was re-administered osimertinib since EGFR-TKIs and IGF1R inhibitor combination therapy was impossible in clinical practice. This had a slight and short-lived effect. CONCLUSIONS: Taken together, we have successfully established a new osimertinib-resistant lung adenocarcinoma cell line with activated IGF1R. These ABC-31 cells will help develop novel therapeutic strategies for patients with lung adenocarcinoma resistant to specific treatment via IGF1R activation.

Background: The guidelines on pharmacotherapy for cancer-related pain advocate active measures against the adverse effects of opioids to increase adherence to medication. However, preventative therapy for the management of nausea and vomiting has not been specified. This study aimed to verify the effects of prophylactic anti emetics in preventing opioid-induced nausea and vomiting. Patients and Methods: We conducted a retrospective analysis of cases at our hospital in which oral opioids or patches were initiated for the management of pain due to malignant tumours from January 2017 to September 2019. Results: Strong opioids were initiated for 349 patients; of these, data for 298 patients were analysed. A total of 193 patients were on anti-emetic prophylaxis. We found that the group that did not receive anti-emetic prophylaxis was significantly more likely to be prescribed an additional anti emetic. Conclusion: Prophylactic administration of anti emetics at the time of initiating opioid analgesics may reduce gastrointestinal toxicity.

Molecular agents targeting the epidermal growth factor receptor (EGFR)-, anaplastic lymphoma kinase (ALK)- or c-ros oncogene 1 (ROS1) alterations have revolutionized the treatment of oncogene-driven non-small-cell lung cancer (NSCLC). However, the emergence of acquired resistance remains a significant challenge, limiting the wider clinical success of these molecular targeted therapies. In this study, we investigated the efficacy of various molecular targeted agents, including erlotinib, alectinib, and crizotinib, combined with anti-vascular endothelial growth factor receptor (VEGFR) 2 therapy. The combination of VEGFR2 blockade with molecular targeted agents enhanced the anti-tumor effects of these agents in xenograft mouse models of EGFR-, ALK-, or ROS1-altered NSCLC. The numbers of CD31-positive blood vessels were significantly lower in the tumors of mice treated with an anti-VEGFR2 antibody combined with molecular targeted agents compared with in those of mice treated with molecular targeted agents alone, implying the antiangiogenic effects of VEGFR2 blockade. Additionally, the combination therapies exerted more potent antiproliferative effects in vitro in EGFR-, ALK-, or ROS1-altered NSCLC cells, implying that VEGFR2 inhibition also has direct anti-tumor effects on cancer cells. Furthermore, VEGFR2 expression was induced following exposure to molecular targeted agents, implying the importance of VEGFR2 signaling in NSCLC patients undergoing molecular targeted therapy. In conclusion, VEGFR2 inhibition enhanced the anti-tumor effects of molecular targeted agents in various oncogene-driven NSCLC models, not only by inhibiting tumor angiogenesis but also by exerting direct antiproliferative effects on cancer cells. Hence, combination therapy with anti-VEGFR2 antibodies and molecular targeted agents could serve as a promising treatment strategy for oncogene-driven NSCLC.

AIM: Evidence is lacking on the best standard method for forced diuresis to prevent cisplatin-induced nephrotoxicity. We compared the cisplatin-induced nephrotoxicity prevention effect of furosemide or mannitol in patients with advanced non-small cell lung cancer. METHODS: Patients with advanced non-small cell lung cancer suitable to receive cisplatin-containing regimen were randomly assigned to receive furosemide or mannitol with appropriate hydration. The primary endpoint was the proportion of ≥ grade 1 serum creatinine elevation in the first cycle. RESULTS: The trial was terminated early with 44 (22 per arm) of the planned 66 patients because of slow accrual. Patients' characteristics were well balanced with median baseline creatinine clearance of 98.0 and 95.1 mL/min in the furosemide and mannitol arms, respectively. In the first cycle, two (9%) and four (18%) patients developed grade 1 creatinine elevation (P = .66), respectively, despite no ≥ grade 2 toxicity. The median times to develop the worst creatinine score were 10 and 8 days, respectively. For all cycles, median times to recover to grade 0 were 56 and 20 days, respectively. The furosemide arm was characterized by relatively high urine output after cisplatin administration (900 vs 550 mL/h), low frequency of unplanned additional hydration (14% vs 32%), and high incidence of hyponatremia (18% and 5%) compared with the mannitol arm. Both arms showed similar progression-free survival and overall survival. CONCLUSION: The preventive effect of the two forced diuretics on cisplatin-induced nephrotoxicity was not significantly different. However, the two diuretics have some distinct types of clinical presentations.

Alectinib is a key drug for treating anaplastic lymphoma kinase (ALK)-positive non-small-cell lung cancer (NSCLC). Alectinib-induced hepatotoxicity is less common than that through other ALK inhibitors, such as crizotinib or ceritinib. Herein, we describe a case of ALK-positive adenocarcinoma successfully treated with lorlatinib after developing alectinib-induced hepatotoxicity. A 57-year-old Japanese man received alectinib as first-line therapy for ALK-positive NSCLC. After 79 days, alectinib was discontinued because of hepatotoxicity and later restarted at 150 mg/day, inducing hepatotoxicity again after 64 days. Switching to lorlatinib treatment (continued for >4 months) caused no severe adverse effects. Hence, lorlatinib may be useful for patients experiencing alectinib-induced hepatotoxicity.

Necrotizing sarcoid granulomatosis (NSG) is a rare disease that presents with nodular lung lesions and necrosis. The pathology is consistent with sarcoidosis, but the necrosis can lead to a diagnosis of tuberculosis. Herein, we report a rare case of NSG that recurred four years after the initial diagnosis was made by surgical lung biopsy. A 51-year-old woman was initially referred to our hospital for the evaluation of multiple lung nodules. The pathological evaluation of a lung biopsy showed granulomas with necrosis and the infiltration of lymphocytes; thus, she was diagnosed with NSG. The lung nodules gradually improved after the diagnosis and we continued to follow her even though she did not require treatment. Four years after her initial diagnosis, she complained of back pain. Upon evaluation, we found that multiple lung nodules had recurred. Bronchoscopy also revealed a tracheal polypoid lesion, which showed granulomas with necrosis pathologically. Therefore, we diagnosed her with the recurrence of NSG. After the corticosteroid therapy, multiple lung nodules drastically improved. NSG patients should be carefully followed-up over several years, even if they do not require treatment.
