RESUMO
OBJECTIVES: Thoracoscopy under local anaesthesia is widely performed to diagnose malignancies and infectious diseases. However, few reports have described the use of this procedure for diagnosing and treating intrathoracic infections. This study aimed to evaluate the safety and efficacy of thoracoscopy under local anaesthesia for the management of intrathoracic infections. RESULTS: Data from patients who underwent thoracoscopy procedures performed by chest physicians under local anaesthesia at our hospital between January 2018 and December 2023 were retrospectively reviewed. We analysed their demographic factors, reasons for the examinations, diseases targeted, examination lengths, anaesthetic methods used, diagnostic and treatment success rates, as well as any adverse events. Thirty patients were included. Of these, 12 (40%) had thoracoscopies to diagnose infections, and 18 (60%) had them to treat pyothorax. In terms of diagnosing pleurisy, the causative microorganism of origin was identified via thoracoscopy in only three of 12 (25.0%) patients. For diagnosing pyothorax, the causative microorganism was identified in 7 of 18 (38.9%) patients. Methicillin-resistant Staphylococcus aureus was the most common causative microorganism identified. The treatment success rates were very high, ranging between 94.4 and 100%, whereas the identification rate of the causative microorganisms behind infections was low, ranging between 25.0 and 38.9%. The most frequent adverse events included perioperative hypoxaemia and pain. There were two (6.7%) serious adverse events of grade ≥ 3, but none resulted in death. CONCLUSIONS: The efficacy of managing intrathoracic infections through thoracoscopy under local anaesthesia is commendable. Nonetheless, the diagnostic accuracy of the procedure, regarding the precise identification of the causative microorganisms responsible for intrathoracic infections, persists at a notably low level, presenting a substantial clinical hurdle.

Background: It is known that the mortality of pneumonia in patients with risk factors for aspiration is worse than that in those without these risk factors. However, it is still unknown which risk factors for aspiration predict prognosis. Therefore, we aimed to determine which risk factors for aspiration are associated with death or prolonged hospitalization. Methods: We prospectively followed patients with community-acquired pneumonia at a single hospital providing acute to chronic care in Japan until they died or were discharged. Patients at any risk of aspiration were included. The associations between pneumonia severity, individual risk factors for aspiration, and in-hospital death or prolonged hospitalization were investigated. Overall survival was estimated by the Kaplan - Meier method, and the factors associated with in-hospital death or prolonged hospitalization were investigated by multivariate analysis using factors selected by a stepwise method. Results: In total, 765 patients with pneumonia and risk factors for aspiration were recruited. One hundred and ten patients deceased, and 259 patients were hospitalized over 27 days. In-hospital death increased as the number of risk factors for aspiration increased. In the multivariate analysis, male, impaired consciousness, acidemia, elevated blood urea nitrogen, and bedridden status before the onset of pneumonia were associated with in-hospital death (odds ratio [OR]: 2.5, 2.5, 3.6, 3.1, and 2.6; 95% confidence interval [CI]: 1.6-4.1, 1.4-4.2, 1.6-8.0, 1.9-5.0, and 1.6-4.2 respectively). In the Cox regression analysis, these factors were also associated with in-hospital death. None of the vital signs at admission were associated. Tachycardia, elevated blood urea nitrogen, hyponatremia, and bedridden status were associated with hospitalization for >27 days (OR: 4.1, 2.3, 4.3, and 2.9; 95% CI: 1.3-12.9, 1.5-3.4, 2.0-9.4, and 2.0-4.0, respectively). Conclusions: Blood sampling findings and bedridden status are useful for predicting in-hospital mortality and long-term hospitalization in patients with pneumonia and any risk factor for aspiration.
RESUMO
BACKGROUND: Nontuberculous mycobacterial pulmonary disease (NTM-PD) often exhibits pulmonary function impairment, such as obstructive or restrictive pattern, with variation among patients according to the damaged lesions in the lung. METHODS: Patients with NTM-PD were consecutively enrolled between September 2019 and December 2020 at the Respiratory Infection Clinic of our hospital. Patients' data were comprehensively collected through laboratory examinations, PFT, chest computed tomography, and questionnaires for the assessment of subjective symptoms and health-related quality of life (HRQOL). Hierarchical cluster analysis was performed using PFT parameters to compare the clinical findings among clusters. RESULTS: Data of 104 patients were analyzed and classified into four clusters. The restrictive pattern with decreased forced expiratory volume in 1 s (FEV1) group showed high serum C-reactive protein and low albumin levels, severe radiological findings, and low HRQOL. In the restrictive pattern with preserved FEV1 group, HRQOL was as low as that in the restrictive pattern with decreased FEV1 group, and bacterial exacerbation was observed relatively frequently. HRQOL in the obstructive impairment group was maintained in comparison with that in the normal group. CONCLUSION: NTM-PD phenotypes were identified using cluster analysis based on PFT. Two different severe phenotypes were also observed. In the early stages of NTM-PD, PFT may be useful in recognizing disease progression.

BACKGROUND: The substantial heterogeneity of clinical presentations in patients with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pneumonia still requires robust chest computed tomography analysis to identify high-risk patients. While extension of ground-glass opacity and consolidation from peripheral to central lung fields on chest computed tomography (CT) might be associated with severely ill conditions, quantification of the central-peripheral distribution of ground glass opacity and consolidation in assessments of SARS-CoV-2 pneumonia remains unestablished. This study aimed to examine whether the central-peripheral distributions of ground glass opacity and consolidation were associated with severe outcomes in patients with SARS-CoV-2 pneumonia independent of the whole-lung extents of these abnormal shadows. METHODS: This multicenter retrospective cohort included hospitalized patients with SARS-CoV-2 pneumonia between January 2020 and August 2021. An artificial intelligence-based image analysis technology was used to segment abnormal shadows, including ground glass opacity and consolidation. The area ratio of ground glass opacity and consolidation to the whole lung (GGO%, CON%) and the ratio of ground glass opacity and consolidation areas in the central lungs to those in the peripheral lungs (GGO(C/P)) and (CON(C/P)) were automatically calculated. Severe outcome was defined as in-hospital death or requirement for endotracheal intubation. RESULTS: Of 512 enrolled patients, the severe outcome was observed in 77 patients. GGO% and CON% were higher in patients with severe outcomes than in those without. Multivariable logistic models showed that GGO(C/P), but not CON(C/P), was associated with the severe outcome independent of age, sex, comorbidities, GGO%, and CON%. CONCLUSION: In addition to GGO% and CON% in the whole lung, the higher the ratio of ground glass opacity in the central regions to that in the peripheral regions was, the more severe the outcomes in patients with SARS-CoV-2 pneumonia were. The proposed method might be useful to reproducibly quantify the extension of ground glass opacity from peripheral to central lungs and to estimate prognosis.

Pulmonary cryptococcal infections are fungal infections that often occur in immunocompromised patients and present with a variety of radiographic patterns ranging from nodular to infiltrative shadows. In the present case, we experienced a rare case of organizing pneumonia due to cryptococcal infection in a 71-year-old woman with rheumatoid arthritis. Transbronchial lung biopsy showing fibrotic changes in the alveolar walls, small granulation lesions and cryptococcal organisms with positive Grocott staining. Serum cryptococcal antigen was also found to be positive. Based on these findings, we confirmed the diagnosis of secondary organizing pneumonia due to cryptococcal infection. Treatment with corticosteroids and antifungal drugs led to improvement of the cough and reduction of organizing pneumonia. In immunocompetent patients with organizing pneumonia, it is essential to perform bronchoscopic lung biopsies and serum antigen tests to search for the cause, whenever possible, as it may be due to an infection caused by Cryptococcus, as in the present case.
RESUMO
BACKGROUND: There have been several reports demonstrating the safety of flexible bronchoscopy (FB) in the elderly, but none have focused specifically on lung cancer, which is a frequent biopsy procedure. METHODS: In this study, we retrospectively evaluated the safety of FB and subsequent treatment in elderly patients with suspected primary lung cancer. Elderly patients were defined as 75 years of age or older. RESULTS: A total of 141 patients, 77 in the elderly group and 64 in the nonelderly group, were reviewed. The median age of the elderly group was 80 years. Transbronchial lung biopsy was performed in more than 80% of all patients. Primary lung cancer was diagnosed in 42 (54.4%) of the elderly group and 35 (54.7%) of the nonelderly group (p = 0.38). Approximately 70% of the elderly patients with a confirmed diagnosis were treated, while more than half of the undiagnosed elderly patients had best supportive care. Complications such as bleeding, pneumothorax, fever, and pneumonia were similar in the elderly and nonelderly groups. CONCLUSIONS: This study suggests that flexible bronchoscopy can be performed as safely in the elderly as in the nonelderly. Furthermore, even elderly patients may have a greater chance of receiving treatment when a definitive diagnosis is achieved.

Searching for driver gene alteration is a prerequisite for chemotherapy of non-small cell lung cancer. Due to its high sensitivity and concordance rate, the Amoy Dx Pan Lung Cancer PCR panel has been approved and is widely used in Japan. In this report, we describe a case in which a positive result for Kristen rat sarcoma virus (KRAS) exon2 p.G12F, a rare KRAS mutation, may have led to a false-positive result for KRAS exon2 p.G12C on AMOY. Genetic analysis in this case was performed by LC-SCRUM-Asia.

BACKGROUND: Pneumothorax is a known sequela of coronavirus disease 2019 (COVID-19). However, the clinical features of pneumothorax associated with COVID-19 have not been fully elucidated. METHODS: Patients who developed pneumothorax within 6 months of being diagnosed with COVID-19 were retrospectively analysed at two institutions. We investigated the background factors, COVID-19 severity and treatment, timing of pneumothorax onset, treatment modalities, treatment duration, and prognosis of these patients. RESULTS: A total of 21 patients were diagnosed with pneumothorax within 6 months of COVID-19 diagnosis. The combined incidence rate of pneumothorax at two institutions was 0.89 %. The mean age of these patients was 72.5 years, and they were predominantly male (90.5 %), with a history of smoking (76.1 %). The most frequent comorbidity was hypertension, followed by type 2 diabetes mellitus, COPD, and malignancy. Approximately 76 % of the patients had moderate or severe disease requiring oxygenation. Moreover, 90.5 % of these patients were taking antiviral drugs; 52.4 %, immunosuppressant agents (baricitinib/tocilizumab); and 66.7 % were on dexamethasone. The median time to the onset of pneumothorax was 15.0 days, and 86 % of cases occurred within 1 month of COVID-19 diagnosis. Bilateral pneumothorax and pneumomediastinum were noted in one patient each. Chest drainage was performed in 71.4 % of the patients. The mean treatment duration for pneumothorax was 14.1 days, and the 30-day mortality rate was 28.6 %. CONCLUSION: Pneumothorax associated with COVID-19 was more common in patients with moderate or severe disease requiring oxygenation, and occurred within 1 month of COVID-19 diagnosis. Pneumothorax associated with COVID-19 is a serious complication with a high mortality rate and clinicians should pay attention to it.

BACKGROUND: Wearing facemasks in public is effective in preventing viral transmission. However, no study has evaluated the impact of wearing facemasks during exercise on dyspnea in patients with chronic pulmonary infections from multifaceted aspects, including sensory qualities and emotional responses. The aim of this study was to evaluate facemask-related dyspnea during exercise in this patient population. METHODS: We conducted a randomized crossover study involving adult patients with non-tuberculous mycobacterial pulmonary disease (NTM-PD) or bronchiectasis who participated in exercise sessions, both with (mask-on) and without (mask-off) surgical facemasks. The sensory and emotional dimensions of dyspnea during each exercise session were assessed using the Multidimensional Dyspnea Profile. Statistical analyses were performed to identify factors associated with worsening scores for each dimension. RESULTS: Thirty-four patients (mean age [standard deviation]: 71.6 [8.6] years) were included in the analysis. The median [interquartile range] total scores for the sensory and emotional dimensions of dyspnea were 3.5 [1, 9.5] (mask-off) vs. 10 [5.5, 23.8] (mask-on) (P < 0.001) and 0 [0, 5] (mask-off) vs. 3 [0.8, 10.3] (mask-on) (P = 0.115), respectively. "Air hunger" was the primary sensory descriptor of mask-related dyspnea. Vital capacity (VC) < 80% of the predicted value was a significant risk factor for worsening sensory dimension scores when wearing masks (odds ratio [95% confidence interval]: 5.5 [1.16-26.1], P = 0.038). CONCLUSIONS: The findings of this study indicate that patients with NTM-PD or bronchiectasis, particularly those with VC <80% of the predicted value, are likely to experience the sensory dimension of dyspnea during exercise while wearing surgical facemasks.

Introduction: Granulocyte colony-stimulating factor (G-CSF), including pegfilgrastim, increases the peripheral blood leukocyte count and is widely used in clinical practice in combination with cytotoxic chemotherapy. The most frequent side effects of G-CSF are pain and fever; aortitis, in contrast, is a rare and serious side effect. Case Presentation: A 73-year-old man with small-cell lung cancer was treated with a full dose of a combination of carboplatin/etoposide/durvalumab and pegfilgrastim. The patient developed fever and right ear pain 12 days after pegfilgrastim administration and was diagnosed with aortitis by contrast-enhanced computed tomography 5 days later. Because the patient had already been administered the immune checkpoint inhibitor and had a history of hepatitis B, the patient was followed up without corticosteroid administration, and the patient's symptoms resolved spontaneously. Conclusion: In situations where immunosuppression should be avoided, we believe that follow-up without corticosteroids for G-CSF-induced aortitis is a promising option.
RESUMO
Osimertinib, a third-generation tyrosine kinase inhibitor, is the first-line treatment for metastatic non-small cell lung cancer (NSCLC) with sensitizing epidermal growth factor receptor (EGFR) mutations. It is known to cause drug-induced cardiotoxicity, including QT prolongation syndrome, heart failure, and ventricular arrhythmias, which can lead to sudden death. Once severe arrhythmias occur, it is difficult to continue osimertinib treatment. We report a case of a 66-year-old woman with recurrent NSCLC after concurrent chemoradiotherapy who experienced osimertinib-induced ventricular arrhythmia-causing syncope. The patient was initially treated with concurrent chemoradiotherapy, and genetic testing revealed EGFR exon 19 deletion. Three years following treatment initiation, the primary tumor progressed, and new bone metastases developed. The patient was diagnosed with recurrent NSCLC and was treated with targeted therapy with osimertinib. On the 10th day of osimertinib administration, syncope occurred. Electrocardiography showed polymorphic non-sustained ventricular tachycardia, which was believed to be the cause of syncope. The patient was switched to erlotinib. Two and a half years later, disease progression in the primary lesion was observed. A liquid biopsy revealed an EGFR T790M resistance mutation. Therefore, osimertinib (40 mg) was administered every alternate day. After confirming the absence of palpitations and arrhythmias on electrocardiogram, the osimertinib dosing was increased to 40 mg daily. Thereafter, no further events occurred, and tumor shrinkage was observed. Low-dose osimertinib rechallenge after induced ventricular arrhythmia may be considered an option under close monitoring; however, osimertinib rechallenge must be carefully selected based on the risk-benefit analysis.
RESUMO
Background: Flexible bronchoscopy (FB) is a common method used for diagnostic sampling of the thorax. Although the safety and efficacy of FB in the general population are well-established, data on the elderly population are limited. This study aimed to determine the safety and efficacy of FB in elderly people aged ≥80 years. Materials and Methods: We retrospectively studied elderly patients aged ≥80 years who underwent FB at our hospital between April 2021 and March 2022. Outcomes, such as indications, sampling methods, diagnostic results, and complications, were compared with those of a control group of patients aged 18-79 years. Results: In total, 247 patients (154 men) were included in the study, with 65 and 182 patients in the elderly and non-elderly groups, respectively. The most frequent indication for FB was the presence of a mass or nodule, with transbronchial lung biopsy, transbronchial biopsy, and endobronchial ultrasound-guided transbronchial needle aspiration performed in 162 (65.6%), 29 (11.7%), and 36 (15.6%) patients, respectively. FB led to a diagnosis in 36 (57.1%) and 103 (56%) patients in the elderly and non-elderly groups, respectively, with no significant difference observed. There were no patient deaths or significant differences in the incidence of hemorrhage, hypoxia, pneumothorax, fever, or pneumonia between the two groups. Conclusions: The findings of this study indicate that FB can be performed effectively and safely in elderly patients aged ≥80 years, similar to non-elderly patients.

Conclusiones: Los resultados de este estudio indican que la FB se puede Los resultados de este estudio indican que la FB puede realizarse de forma eficaz y segura en pacientes de edad ≥80 años, de forma similar a los pacientes no ancianos.
RESUMO
The effect of inhaled corticosteroids (ICS) and biologics on the humoral immune response following severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) mRNA vaccination in patients with asthma is unknown. We prospectively evaluated the humoral immune response 3 weeks (T1) and 6 months (T2) after the second dose of BNT162b2 in 30 SARS-CoV-2-naïve patients with asthma. We measured anti-spike immunoglobulin G (IgG) titers and serum-neutralizing activity against the ancestral SARS-CoV-2 strain. The anti-spike IgG titer and neutralizing activity did not differ significantly between the biologics and non-biologics groups at T1 (P = 0.708 and P = 0.417, respectively) or T2 (P = 0.299 and P = 0.492, respectively). In the multivariate analysis, age and sex were significantly associated with the magnitude of the humoral immune response; however, the use of biologics and ICS dose were not, suggesting that these would not affect BNT162b2 immunogenicity in patients with asthma. Larger studies are needed to validate these findings.

The aim of this study was to longitudinally evaluate the undetermined impact of methotrexate (MTX) on the cumulative immunogenicity elicited by three doses of SARS-CoV-2 mRNA vaccination in patients with rheumatoid arthritis (RA). We prospectively evaluated vaccine-induced immune responses following the first dose, 1 and 6 months after the second dose, and 1 month after the third dose of BNT162b2 or mRNA-1273 in 144 SARS-CoV-2 naïve participants (70 patients with RA, 29 disease controls without immunosuppressive conditions, and 45 healthy controls). Humoral immune responses were assessed by quantifying anti-spike IgG antibody titers and the capacity of circulating antibodies to neutralize the ancestral SARS-CoV-2 strain and the Alpha, Delta, and Omicron variants. Vaccine-induced T-cell responses were measured using an interferon-gamma release assay. At 1 and 6 months after the second dose, anti-spike titers were highest in healthy controls, followed by disease controls and patients with RA. Multivariate analyses revealed that MTX treatment was significantly associated with a decrease in anti-spike titers, neutralizing activity, and SARS-CoV-2-specific interferon-gamma levels. Furthermore, MTX dose per body weight was negatively correlated with these two indices of humoral immune response. The third vaccine dose boosted anti-spike titers, especially in patients receiving MTX, while sera from these patients neutralized the Omicron variant far less robustly than those from healthy controls. In conclusion, MTX attenuated immunogenicity following two doses of SARS-CoV-2 mRNA vaccine in patients with RA, particularly resulting in dose-dependent suppression of the humoral immune response. Furthermore, MTX deteriorated the neutralizing activity against the Omicron variant, even after the third immunization.

BACKGROUND: The role of re-immunotherapy in advanced non-small cell lung cancer (NSCLC) remains unclear. No studies have evaluated the re-immunotherapy regimen including anti-cytotoxic T-lymphocyte antigen-4 antibody for lung cancer treatment. This study aimed to investigate the efficacy and safety of re-immunotherapy with nivolumab plus ipilimumab in patients with advanced NSCLC previously treated with anti-programmed death-1 (PD-1) and/or anti-programmed death ligand-1 (PD-L1) antibodies. METHODS: We retrospectively reviewed patients with advanced or recurrent NSCLC who received immunotherapy with nivolumab plus ipilimumab (without concomitant cytotoxic chemotherapy) between November 2020 and November 2022 at the National Hospital Organization Kyoto Medical Center, Kyoto, Japan. Data were extracted from patients who had previously received immunotherapies with anti-PD-1 and/or anti-PD-L1 antibodies. Treatment responses and adverse events were evaluated. RESULTS: Of the 67 patients who received immunotherapy with nivolumab plus ipilimumab, 23 were included in final analysis. The objective response rate was 17%, and the disease control rate was 48% for nivolumab plus ipilimumab therapy. The highest grade of immune-related adverse events was grade 3, occurring in 11% of cases. CONCLUSION: Re-immunotherapy with nivolumab plus ipilimumab after anti-PD-1 and/or anti-PD-L1 immunotherapy may be feasible and provide clinical benefit in selected patients. Further prospective studies are warranted to identify the patient population that may benefit from re-immunotherapy.
RESUMO
This report describes the case of a 79-year-old Japanese man diagnosed with orbital extranodal marginal zone lymphoma (EMZL) and stage IIIA lung cancer. The patient received concurrent chemoradiation for lung cancer with carboplatin/paclitaxel treatment, resulting in regression of both the lymphoma and lung cancer. To our knowledge, this is the first reported case of concurrent orbital EMZL and lung cancer. In this case, a treatment strategy that prioritized lung cancer treatment was deemed appropriate. This case suggests that chemotherapy with carboplatin and paclitaxel may serve as an effective treatment for both lung cancer and lymphoma.
RESUMO
We present a case report of a 92-year-old patient with thoracic empyema, who was successfully treated via CT-guided insertion of a pigtail catheter. The advanced age of the patient often poses challenges in managing pyothorax due to limited physical activity and cognitive decline stemming from decreased activities of daily living. In instances where thoracic drainage is not feasible, the course of treatment is protracted and the prognosis is poor. Our case report exemplifies the successful treatment of pyothorax in a geriatric patient via CT-guided insertion of a pigtail catheter. We believe that this educational case serves as a testament to the fact that even the most aged patients can be successfully treated with resourcefulness.
RESUMO
The coronavirus disease 2019 (COVID-19) pandemic has restricted many medical practices. We aimed to investigate the impact of the COVID-19 pandemic on the number of bronchoscopies, outpatients, and hospital admissions. We retrospectively analyzed the number of outpatients, admissions, and bronchoscopies performed between March 2020 and May 2022. We defined "Peak month of the pandemic," "Wave of the pandemic," "Month in the wave," and "Period of a state of emergency" for each analysis. In the first year of the COVID-19 pandemic, analysis of variance (ANOVA) in linear mixed models indicated significant effects of "month in each wave" on the number of bronchoscopies (P = .003), outpatients (P = .041), and admissions (P = .017). The number of outpatients, admissions, and bronchoscopies was significantly influenced by the first wave of the COVID-19 pandemic. In contrast, in the second year of the COVID-19 pandemic, a mixed-ANOVA indicated significant effects of "month in each wave" only on the number of outpatients (P = .020) but no significant effects on the number of bronchoscopies (P = .407) and admissions (P = .219). During the second year of the pandemic, the number of bronchoscopies and admissions was not significantly affected by the waves of the pandemic. There were no significant differences in the number of admissions and bronchoscopies between the fourth and sixth waves. Although the number of bronchoscopies was found to be significantly affected in the early stages of the COVID-19 pandemic, the impact of the pandemic was much more limited thereafter.

Background: Influenza-related bacterial pneumonia is a leading complication of influenza infection. However, the differences in the incidence rates and risk factors associated with concomitant viral/bacterial pneumonia (CP) and secondary bacterial pneumonia following influenza (SP) remain unclear. This study aimed to clarify the incidence rates of CP and SP following seasonal influenza and identify factors associated with their development. Methods: This retrospective cohort study was conducted using the JMDC Claims Database, a health insurance claims database in Japan. All patients aged <75 years who developed influenza during 2 consecutive epidemic seasons, 2017/2018 and 2018/2019, were analyzed. CP was defined as bacterial pneumonia diagnosed between 3 days before and 6 days after the date of influenza diagnosis, and SP was defined as pneumonia diagnosed 7-30 days after the date of diagnosis. Multivariable logistic regression analyses were performed to identify factors associated with the development of CP and SP. Results: Among the 10 473 014 individuals registered in the database, 1 341 355 patients with influenza were analyzed. The average age at diagnosis (SD) was 26.6 (18.6) years. There were 2901 (0.22%) and 1262 (0.09%) patients who developed CP and SP, respectively. Age 65-74 years, asthma, chronic bronchitis/emphysema, cardiovascular disease, renal disease, malignant tumor, and immunosuppression were significant risk factors for both CP and SP, whereas cerebrovascular disease, neurological disease, liver disease, and diabetes were risk factors specific to CP development. Conclusions: The results determined the incidence rates of CP and SP and identified their risk factors, such as older age and comorbidities.
RESUMO
The transformation to SCLC is a known mechanism of resistance against molecularly targeted therapies. This study reports a patient with untreated lung adenocarcinoma, characterized by a KRAS G12C mutation, which transformed into SCLC before treatment. Both the adenocarcinoma and SCLC components were responsive to sotorasib.
