RESUMO
BACKGROUND: End-of-life discussions for patients with advanced cancer are internationally recommended to ensure consistency of end-of-life care with patients' values. This study examined the elements of end-of-life discussions associated with end-of-life care. MATERIALS AND METHODS: We performed a prospective observational study among consecutive patients with pretreated non-small cell lung cancer after the failure of first-line chemotherapy. We asked oncologists whether they had ever discussed "prognosis," "do not attempt resuscitation," "hospice," and "preferred place of death" with a patient at baseline. The quality of life (QOL) and depressive symptoms of patients were assessed using validated questionnaires at baseline and 3 months later. The end-of-life care that patients received was investigated using medical records. Oncologists' compassion and caregivers' preferences for hospice care were also assessed using questionnaires. Multiple regression analyses were conducted to examine the association between elements of end-of-life discussions and patient-reported outcomes as well as actual end-of-life care. RESULTS: We obtained 200 valid responses at baseline, 147 valid responses 3 months later, and 145 data points for medical care at the end-of-life stage. No element of the end-of-life discussion between the patient and their oncologist was significantly associated with patients' reported outcomes or actual end-of-life care. In addition, oncologists' compassion was significantly associated with improvement in both comprehensive QOL and depressive symptoms, and caregivers' preferences for hospice care and high educational level were significantly associated with hospice death. CONCLUSION: Oncologist-patient alliances and caregivers' involvement in end-of-life discussions may be influential in achieving optimal end-of-life care.

BACKGROUND: Targeted therapy is now the standard of care in driver-oncogene-positive non-small cell lung cancer (NSCLC). Its initial clinical effects are remarkable. However, almost all patients experience treatment resistance to targeted therapy. Hence, chemotherapy is considered a subsequent treatment option. In patients with driver-oncogene-negative NSCLC, combined immune checkpoint inhibitors (ICIs) and chemotherapy as the first-line therapy has been found to be beneficial. However, the efficacy of ICI plus chemotherapy against driver-oncogene-positive NSCLC other than epidermal growth factor receptor mutation and anaplastic lymphoma kinase fusion is unclear. METHODS: Using the hospital medical records, we retrospectively reviewed advanced or recurrent NSCLC patients who were treated with chemotherapy with or without ICIs at Aichi Cancer Center Hospital between January 2014 and January 2023. Patients with druggable rare mutations such as KRAS-G12C, MET exon 14 skipping, HER2 20 insertion, BRAF-V600E mutations, and ROS1 and RET rearrangements were analyzed. RESULTS: In total, 61 patients were included in this analysis. ICI plus chemotherapy was administered in 36 patients (the ICI-chemo group) and chemotherapy in 25 patients (the chemo group). The median progression-free survival (PFS) rates were 14.0 months in the ICI-chemo group and 4.8 months in the chemo group (hazard ratio [HR] = 0.54, 95% confidence interval [CI] = 0.28-1.01). The median overall survival rates were 31.3 and 21.7 months in the ICI-chemo and chemo groups, respectively (HR = 0.70, 95% CI = 0.33-1.50). Multivariate Cox regression analysis of PFS revealed that HER2 exon 20 insertion mutation was significantly associated with a poorer PFS (HR: 2.39, 95% CI: 1.19-4.77, P = 0.014). Further, ICI-chemo treatment was significantly associated with a better PFS (HR: 0.48, 95% CI: 0.25-0.91, P = 0.025). CONCLUSION: ICI plus chemotherapy improves treatment efficacy in rare driver-oncogene-positive NSCLC.

BACKGROUND: The treatment of lung cancer has made dramatic progress in the past decade, but due to the high cost of drugs, the total pharmaceutical cost has been rising explosively. There are currently no data available in Japan on which regimens are used, to what extent they are used, and what their total cost is. METHODS: Sixty Japanese centers belonging to the Lung Cancer Study Group of the Japan Clinical Oncology Group were surveyed for information about the first-line treatment for advanced lung cancer in practice from July 2021 to June 2022. Three types of cancer were included: driver gene mutation-negative NSCLC, EGFR mutation-positive NSCLC, and extensive-stage small cell lung cancer (ES-SCLC). RESULTS: Recent treatment costs for ICIs or ICI plus chemotherapy were about 20-55 times higher than those for conventional chemotherapy. Of the 3738 patients with driver gene aberration-negative NSCLC, 2573 (68.8%) received treatments with monthly cost of 500 000 Japanese yen (JPY) or more; 2555 (68.4%) received ICI therapy. Of the 1486 patients with EGFR mutation-positive NSCLC, 1290 (86.8%) received treatments with a monthly cost of 500 000 JPY or more; 1207 (81.2%) received osimertinib. ICI treatments with a monthly cost of 500 000 JPY or more were administered to 607 (56.3%) of 1079 patients with ES-SCLC. Elderly NSCLC patients received slightly more high-cost treatment than younger patients. CONCLUSION: Recent treatments cost many times more than conventional chemotherapy. This study revealed that high-cost treatments were widely used in advanced lung cancer and some of high-cost treatments were used despite the lack of clear evidence. Physicians should pay attention to the cost of treatments they use.
RESUMO
PURPOSE: Determining whether patients' unrealistic expectations of chemotherapy as a cure were associated with their perception of the disclosure of incurability. METHODS: This prospective study included consecutive patients with pretreated non-small cell lung cancer from four study sites. Patients and their oncologists were asked whether they perceived the disclosure of cancer incurability. Patients were also asked if they thought that chemotherapy was curative. We followed up on whether the deceased patients received specialized palliative care 14 months after their last enrollment. Multiple regression analyses were conducted to examine the association between the expectation of chemotherapy as a cure and patient/oncologist-reported perceptions of the disclosure of incurability. RESULTS: We analyzed 200 patients, 77 (38.5%) of whom had unrealistic expectations of a cure. Based on patients' perceptions, incurability was disclosed to 138 (69.0%) patients, and based on their oncologists' perceptions, incurability was disclosed to 185 (92.5%) patients (patient/oncologist agreements, κ = 0.19). Patients without a perception of the oncologist's disclosure of incurability-regardless of their oncologist's perception-were more likely to have unrealistic expectations of a cure than patients for whom both patient and oncologist perceptions were present. Patients who had unrealistic expectations of chemotherapy as a cure were shown to be significantly less likely to have received specialized palliative care, after adjusting for covariates (adjusted OR, 0.45; 95% CI, 0.23-0.91; p = .027). CONCLUSION: Oncologists' disclosure of incurability was not fully recognized by patients, and expectations of chemotherapy as a cure were associated with patients' perception of the disclosure of incurability.

BACKGROUND: Information regarding the status of surgical antimicrobial prophylaxis (SAP) in Japanese hospitals is lacking. This study aimed to explore the status of SAP prescriptions for surgeries and adherence to Japanese SAP guidelines. METHODS: From February to July 2020, a 1-day multicentre point prevalent survey was conducted at 27 hospitals in Aichi Prefecture, Japan. Patients prescribed SAP were included in this study. The appropriateness of the SAP was evaluated based on the guidelines for selection of antimicrobials and their duration. Surgery was defined as appropriate when all the items were appropriate. RESULTS: A total of 728 patients (7.1 %; 728/10,199) received antimicrobials for SAP. Among them, 557 patients (76.5 %, 557/728) underwent the surgeries described in the guidelines. The overall appropriateness of all surgeries was 33.9 % (189/557). The appropriate selection of antimicrobial before/during and after surgery and their durations were 67.5 % (376/557), 67.5 % (376/557), and 43.3 % (241/557), respectively. The overall appropriateness ranged from 0 % (0/37, oral and maxillofacial surgery) to 58.7 % (88/150, orthopaedic surgery) and 27.7 % (36/130, community hospitals with 400-599 beds) to 47.2 % (17/36, specific hospitals). Cefazolin was the most prevalent antimicrobial prescribed before/during (55.5 %, 299/539), and after (45.1 %, 249/552) surgery. In total, 101 oral antimicrobials were prescribed postoperatively. CONCLUSIONS: SAP adherence by specific surgical fields and hospitals was shown in this study. Intensive intervention and repeated surveillance are necessary to improve SAP prescriptions in Japanese hospitals.

BACKGROUND: Although patients with advanced cancer often have poor prognostic awareness, the most effective communication approach for improving prognostic awareness is unclear. In addition, the association between prognostic awareness and preferences for future medical treatment remains unexplored. MATERIALS AND METHODS: We performed a prospective observational study of consecutive patients with advanced or post-operative recurrent non-small cell lung cancer whose disease had progressed after first-line chemotherapy, and their caregivers. We evaluated patterns of clinical discussions about incurability, prognostic awareness, and preference for future medical treatment at baseline and 3 months later. RESULTS: We obtained 200 valid responses to the questionnaires at baseline and 147 valid responses 3 months later. In addition, 180 caregivers returned valid responses. A total of 54% of patients and 51% of caregivers had accurate awareness at baseline, and 52% of patients had accurate awareness 3 months later. Multiple logistic regression analysis revealed that patients who were informed about incurability in recent and past discussions were significantly more likely to have accurate awareness 3 months later, compared with those who were only informed recently (adjusted odds ratio 5.08; 95% CI, 1.31-19.78; P = .019). Accurate awareness at 3 months was significantly negatively associated with preference for life-prolonging treatment at 3 months after adjusting for covariates (adjusted odds ratio 0.39; 95% CI, 0.17-0.90; P = .028). CONCLUSION: Patients with advanced cancer who had both recent and past discussions about incurability with their oncologists have more accurate prognostic awareness. Improving prognostic awareness could reduce the preference for life-prolonging treatment.

BACKGROUND: Nivolumab, an anti-programmed death 1 (PD-1) monoclonal antibody, has shown survival benefit in clinical trials of various malignant tumors. Nivolumab-induced pneumonitis is major immune-related adverse event (irAE) that is occasionally serious and life-threatening. The aim of this study was to examine the association between pre-existing interstitial lung disease (ILD) on chest computed tomography (CT) and nivolumab-induced pneumonitis among different types of solid tumors. METHODS: We retrospectively collected the clinical data of 311 patients who were diagnosed with non-small cell lung cancer (NSCLC), head and neck cancer (HNC), or gastric cancer (GC), and treated with nivolumab monotherapy. Patients who underwent chest CT immediately before starting nivolumab without previous thoracic radiotherapy or other immune checkpoint inhibitors were eligible. We collected baseline patient characteristics and assessed pre-existing ILD on baseline chest CT. RESULTS: Finally, 188 patients were included in the analysis: 96 patients with NSCLC, 43 patients with HNC, and 49 patients with GC. NSCLC patients had a significantly higher rate of pre-existing ILD compared with HNC/GC patients (P = 0.047). Nivolumab-induced pneumonitis occurred in 11.7% (22 of 188), including 14.6% (14 of 96) of NSCLC, and 8.7% (8 of 92) of HNC/GC. Univariate and multivariate logistic regression analyses revealed that pre-existing ILD (odds ratio, 5.92; 95% confidence interval (CI), 2.07-18.54, P = 0.0008) and male sex (odds ratio, 5.58; 95% CI, 1.01-104.40, P = 0.049) significantly increased the risk of nivolumab-induced pneumonitis. CONCLUSION: Our results indicated that pre-existing ILD and male sex are risk factors for nivolumab-induced pneumonitis in solid tumors.

Immune checkpoint inhibitors (ICIs) have dramatically changed the strategy used to treat patients with non-small-cell lung cancer (NSCLC); however, the vast majority of patients eventually develop progressive disease (PD) and acquire resistance to ICIs. Some patients experience oligoprogressive disease. Few retrospective studies have evaluated clinical efficacy in patients with oligometastatic progression who received local therapy after ICI treatment. We conducted a retrospective analysis of advanced NSCLC patients who received PD-1 inhibitor monotherapy with nivolumab or pembrolizumab to evaluate the effects of ICIs on the patterns of progression and the efficacy of local therapy for oligoprogressive disease. Of the 307 patients treated with ICIs, 148 were evaluated in our study; 42 were treated with pembrolizumab, and 106 were treated with nivolumab. Thirty-eight patients showed oligoprogression. Male sex, a lack of driver mutations, and smoking history were significantly correlated with the risk of oligoprogression. Primary lesions were most frequently detected at oligoprogression sites (15 patients), and 6 patients experienced abdominal lymph node (LN) oligoprogression. Four patients showed evidence of new abdominal LN oligometastases. There was no significant difference in overall survival (OS) between the local therapy group and the switch therapy group (reached vs. not reached, P = .456). We summarized clinical data on the response of oligoprogressive NSCLC to ICI therapy. The results may help to elucidate the causes of ICI resistance and indicate that the use of local therapy as the initial treatment in this setting is feasible treatment option.

The year 2019 was considered to be the first year of cancer genome medicine in Japan, with three gene-panel tests using next-generation sequencing (NGS) techniques being introduced into clinical practice. Among the three tests, the Oncomine CDx Target test was approved under the category of regular molecular testing for lung cancer, which meant that this test could be used to select patients for molecularly targeted drugs. Conversely, the other two tests, NCC OncoPanel and FoundationOne CDx, were assigned to be used under the National Cancer Genome Medicine Network, and implementation was restricted to patients for whom standard treatment was completed or expected to be completed. These NGS tests can detect a series of genetic alterations in individual tumors, which further promotes the development of therapeutic agents and elucidates molecular pathways. The NGS tests require appropriate tissue size and tumor cell content, which can be accessed only by pathologists. In this report, we review the current reimbursement schema in our national healthcare policy and the requirements of the specimens for NGS testing based on the recently published 'Guidance of Gene-panel Testing Using Next-Generation Sequencers for Lung Cancer', by the Japanese Society of Lung Cancer.

There are few reports on the use of salvage surgery for small cell lung cancer (SCLC). Five patients who underwent resection of post-chemoradiotherapy residual lesion/local reprogression of SCLC between 2005 and 2017 were included in the study. We retrospectively reviewed their surgical outcomes and prognosis to assess the feasibility and potential efficacy of salvage surgery. Indications for salvage surgery were local reprogression (four patients) and residual lesion (one patient) with ycN0 disease. Complete pathological resection was achieved in four patients; however, malignant pleural effusion was diagnosed in one patient after the surgery. Morbidity and mortality rates were 0%. Estimated 5-year survival rate was 67%. Recurrence and death after surgery occurred only in the patient with malignant pleural effusion. We demonstrate the feasibility of salvage surgery in SCLC. In carefully-selected patients, especially those without lymph node involvement, salvage surgery may provide effective local control and favorable survival outcomes.

BACKGROUND: Everolimus is a mammalian target of rapamycin inhibitor used in the treatment of multiple tumor types, and its most common toxicity, stomatitis, can affect patient quality of life. Recent studies in breast cancer have supported the efficacy of steroid mouthwash for the prevention of everolimus-associated stomatitis. However, a few studies have been reported to date, and none have examined this effect in other tumor types. METHODS: This single-arm phase 2 study was designed to evaluate the efficacy of steroid-containing mouthwash for the prevention of stomatitis in patients with multiple tumor types receiving everolimus. The primary outcome was incidence of grade ≥ 2 stomatitis at 8 weeks of everolimus with steroid-containing mouthwash prophylaxis. We also assessed the stability of steroid-containing mouthwash components. RESULTS: Twenty-nine patients were evaluated, of which 76% had breast cancer and 24% had neuroendocrine tumors originating in the lung, gastrointestinal tract, pancreas, or of unknown primary origin. Grade ≥ 2 stomatitis incidence at 8 weeks was 28.1% (90% CI 16.2-46.1); the higher confidence limit exceeded the prespecified threshold of 30%. No patients developed grade ≥ 3 stomatitis. Most stomatitis occurred behind the oral cavity, with no lesions observed on the lips or floor of the mouth. CONCLUSIONS: Our findings did not support a prophylactic effect of steroid-containing mouthwash on everolimus-associated stomatitis. Given the needs of prevention of everolimus-associated stomatitis in various tumor types, further studies in a larger population using a randomized controlled trial design are, therefore, required to confirm the efficacy of steroid-containing mouthwash.

BACKGROUND: Cisplatin-based chemoradiotherapy is the standard treatment for unresectable, locally advanced non-small-cell lung cancer (NSCLC). This trial evaluated two experimental regimens that combine chemotherapy with concurrent radiotherapy. METHODS: Eligible patients with unresectable stage III NSCLC were randomised to either the SP arm (S-1 and cisplatin) or VP arm (vinorelbine and cisplatin), with early concurrent thoracic radiotherapy of 60 Gy, comprising 2 Gy per daily fraction. The primary endpoint was the overall survival rate at 2 years (2-year overall survival (OS)) (Study ID: UMIN000002420). RESULTS: From September 2009 to September 2012, 112 patients were enroled. Of the 108 eligible patients, the 2-year OS was 75.6% (80% confidence interval (CI), 67-82%) in the SP arm and 68.5% (80% CI: 60-76%) in the VP arm. The hazard ratio (HR) for death between the two arms was 0.85 (0.48-1.49). The median progression-free survival was 14.8 months for the SP arm and 12.3 months for the VP arm with an HR of 0.92 (0.58-1.44). There were four treatment-related deaths in the SP arm and five in the VP arm. CONCLUSIONS: The null hypotheses for 2-year OS were rejected in both arms. The West Japan Oncology Group will employ the SP arm as the investigational arm in a future phase III study.

BACKGROUND: Lung adenocarcinoma in the young is a rare entity, and the oncogenic genetic alterations (GAs) and clinical characteristics associated with this disease are poorly understood. Conversely, it has been demonstrated that young age at diagnosis defines unique biology in other cancers. For this report, the effects of young age on lung adenocarcinoma are reported. METHODS: The authors retrospectively screened 1746 consecutive patients who were diagnosed with stage I through IV adenocarcinoma between 2009 and 2015 and identified 81 who were aged 40 years or younger at diagnosis. The clinical and genetic characteristics of this younger population were analyzed. RESULTS: Of the 81 younger patients identified, 36 (44%) were men, 36 (44%) were never smokers, and the median age was 36 years (range, 26-40 years). Thirty-three patients (41%) harbored anaplastic lymphoma kinase (ALK) translocations, 24 (30%) had epidermal growth factor receptor (EGFR) mutations, and 2 (2%) had v-Ki-ras2 Kirsten rat sarcoma viral oncogene homolog (KRAS) mutations. Rare oncogenic GAs also were studied in patients who had wild-type ALK/EGFR/KRAS adenocarcinoma, including 4 patients with HER2 mutations, 2 with Ret proto-oncogene (RET) translocations, and 2 with ROS proto-oncogene 1 receptor tyrosine kinase (ROS1) translocations. Notably, oncogenic GAs (P < .001), ALK (P < .001) and ROS1 (P = .033) translocations, and HER2 mutations (P < .001) were associated with young age, and a similar trend was observed for RET translocations (P = .108). Younger patients who had adenocarcinoma without GAs had a significantly worse prognosis compared with older patients without GAs (overall survival, 8.9 vs 16.4 months; P < .001) and patients with GAs (24.9 months; P < .001). CONCLUSIONS: Younger patients with adenocarcinoma have a distinctly unique prevalence of oncogenic GAs. Comprehensive oncogenic GA screening is especially recommended for personalized medicine strategies in this population. Cancer 2017;123:1731-1740. © 2017 American Cancer Society.

For symptom alleviation, subcutaneous continuous injection of octreotide was administered to a patient with pancreatic neuroendocrine tumor (NET) accompanied by multiple hepatic metastases and ascites. The level of the tumor marker neuron-specific enolase decreased to the normal range and cystic necrosis of the tumors was confirmed. There have been some reports on the antineoplastic effects of octreotide on pancreatic NET; therefore, octreotide appears to be a valid option as a therapeutic agent in patients with highly advanced pancreatic NET, in whom administration of molecular targeted or anticancer agents is difficult because of a poor general status.

Interstitial lung disease (ILD) or pneumonitis caused by epidermal growth factor receptor (EGFR) tyrosine kinase inhibitors (TKI) or immune checkpoint inhibitors (ICI) is a major concern in the treatment of non-small cell lung cancer (NSCLC). Whether the addition of vascular endothelial growth factor (VEGF) and VEGF receptor (VEGFR) inhibitors can reduce the incidence of drug-induced ILD remains unclear. We conducted a systematic review to assess the incidence of ILD induced by EGFR-TKIs or ICIs in the presence or absence of VEGF/VEGFR inhibitors in relevant randomized trials between January 2009 and October 2023. The primary outcome was the odds ratio for the incidence of ILD in all patients worldwide and Asians. Secondary outcomes were the odds ratios (ORs) of the incidence at grade-3 or higher ILD in all patients worldwide and Asians. We identified 13 randomized studies, one sub-analysis in the EGFR-TKI group, and three randomized studies in the ICI group. In the EGFR-TKI group, the OR of ILD incidence at any grade with VEGF/VEGFR inhibitors was 0.54 (95% CI, 0.32-0.90; p = 0.02), which represented a significantly lower incidence than that without VEGF/VEGFR inhibitors. Contrarily, the OR of ILD incidence at grade ≥ 3 with VEGF/VEGFR inhibitors was 1.00 (95% CI, 0.43-2.36; p = 0.99). In all subjects in the ICI group, the OR of ILD incidence at any grade with VEGF/VEGFR inhibitors was 0.78 (95% CI, 0.51-1.21; p = 0.27). The systematic review demonstrated that the addition of VEGF/VEGFR inhibitors could reduce the incidence of drug-induced ILD at any grade caused by EGFR-TKI in patients with NSCLC but could not reduce that at grade ≥ 3. The ILD induced by ICIs remains undetermined owing to the limited number of randomized trials for which ILD data are available.

RESUMO
In patients with non-small cell lung cancer (NSCLC), pre-existing interstitial lung disease (ILD) is a risk factor for the development of pneumonitis induced by immune checkpoint inhibitors (ICIs). Anti-fibrotic agents, including nintedanib, reduce the potential for acute exacerbation of idiopathic pulmonary fibrosis (IPF). However, whether nintedanib can reduce the potential for ICI-induced pneumonitis is unknown. From among 140 patients with NSCLC treated with atezolizumab monotherapy at our institution, we retrospectively investigated 4 patients with pre-existing ILD treated concurrently with nintedanib. On computed tomography (CT), a usual interstitial pneumonia (UIP) pattern was present in one patient, probable UIP pattern in one patient, and indeterminate for UIP pattern in two patients. Of those four patients with pre-existing ILD, two achieved a partial response to ICI treatment, with response durations of 8.1 and 7.6 months. The other two patients experienced progressive disease. Notable adverse events included the development of non-symptomatic grade 1 pneumonitis in the patient with a probable UIP pattern and grade 3 lower gastrointestinal hemorrhage in another patient. None of the patients experienced a worsening of respiratory symptoms. In patients with NSCLC and pre-existing ILD, nintedanib might reduce the potential for ICI-induced pneumonitis and enhance the antitumor effect.
RESUMO
Introduction: Lorlatinib is an ALK tyrosine kinase inhibitor approved in Japan for the treatment of advanced ALK+ NSCLC. There has been little evidence about lorlatinib efficacy after first-line (1L) alectinib in clinical practice in Japan. Methods: We retrospectively analyzed patients with advanced ALK+ NSCLC previously treated with 1L alectinib at multiple sites in Japan. Primary objectives were to collect patient demographics at baseline and estimate time to treatment failure (TTF) with second-line (2L) or third-line (3L) or later line (≥3L) lorlatinib treatment. Secondary objectives included objective response rate (ORR) with lorlatinib, reason for discontinuation and time to last treatment failure with lorlatinib, TTF and ORR of alectinib, and combined TTF. Results: Among the 51 patients included in the study, 29 (56.9%) received 2L and 22 (43.1%) received ≥3L lorlatinib treatment. At lorlatinib initiation, brain metastases were reported in 25 patients (49.0%), and 32 (62.7%) had an Eastern Cooperative Oncology Group performance status of 0 or 1. Median TTF with lorlatinib was 11.1 months (95% confidence interval [CI]: 4.6-13.8) in any line, 10.8 months (95% CI: 3.9-13.8) in 2L, and 11.5 months (95% CI: 2.9-not reached) in ≥3L. Median TTF was 11.5 months (95% CI: 3.9-not reached) in patients with brain metastases at lorlatinib initiation and 9.9 months (95% CI: 4.3-13.8) in patients without brain metastases. ORR was 35.7% with any-line lorlatinib treatment. Conclusions: Patient characteristics and efficacy were comparable with previous reports when lorlatinib was given after 1L alectinib in patients with ALK+ NSCLC.
RESUMO
PURPOSE: Trastuzumab deruxtecan (T-DXd) 5.4 and 6.4 mg/kg showed robust antitumor activity in multiple cancer indications; however, T-DXd 5.4 mg/kg has not been evaluated in patients with previously treated human epidermal growth factor receptor 2-mutant (HER2m; defined as single-nucleotide variants and exon 20 insertions) metastatic non-small-cell lung cancer (mNSCLC). METHODS: DESTINY-Lung02, a blinded, multicenter, phase II study, investigated T-DXd 5.4 mg/kg once every 3 weeks for the first time in previously treated (platinum-containing therapy) patients with HER2m mNSCLC and further assessed T-DXd 6.4 mg/kg once every 3 weeks in this population. The primary end point was confirmed objective response rate (ORR) per RECIST v1.1 by blinded independent central review. RESULTS: One hundred fifty-two patients were randomly assigned 2:1 to T-DXd 5.4 or 6.4 mg/kg once every 3 weeks. As of December 23, 2022, the median duration of follow-up was 11.5 months (range, 1.1-20.6) with 5.4 mg/kg and 11.8 months (range, 0.6-21.0) with 6.4 mg/kg. Confirmed ORR was 49.0% (95% CI, 39.0 to 59.1) and 56.0% (95% CI, 41.3 to 70.0) and median duration of response was 16.8 months (95% CI, 6.4 to not estimable [NE]) and NE (95% CI, 8.3 to NE) with 5.4 and 6.4 mg/kg, respectively. Median treatment duration was 7.7 months (range, 0.7-20.8) with 5.4 mg/kg and 8.3 months (range, 0.7-20.3) with 6.4 mg/kg. Grade ≥ 3 drug-related treatment-emergent adverse events occurred in 39 of 101 (38.6%) and 29 of 50 (58.0%) patients with 5.4 and 6.4 mg/kg, respectively. 13 of 101 (12.9%) and 14 of 50 (28.0%) patients had adjudicated drug-related interstitial lung disease (2.0% grade ≥ 3 in each arm) with 5.4 and 6.4 mg/kg, respectively. CONCLUSION: T-DXd demonstrated clinically meaningful responses at both doses. Safety profile was acceptable and generally manageable, favoring T-DXd 5.4 mg/kg.

The GABA-synthesizing enzymes glutamate decarboxylase (GAD)1 and GAD2 are universally contained in GABAergic neurons in the central nervous system of the mouse and rat. The two isoforms are almost identically expressed throughout the brain and spinal cord. By using in situ hybridization, we found that the mouse lateral striatum concentrates medium-sized projection neurons with high-level expression of GAD1, but not of GAD2, mRNA. This was confirmed with several types of riboprobe, including those directed to the 5'-noncoding, 3'-noncoding and coding regions. Immunohistochemical localization of GAD1 also revealed predominant localization of the enzyme in the same striatal region. The lateral region of the mouse striatum, harboring such neurons, is ovoid in shape and extends between interaural +4.8 and +2.8, and at lateral 2.8 and dorsoventral 2.0. This intriguing region corresponds to the area that receives afferent inputs from the primary motor and sensory cortex that are presumably related to mouth and forelimb representations. The lateral striatum is included in the basal ganglia-thalamocortical loop, and is most vulnerable to various noxious stimuli in the neurodegeneration processes involving the basal ganglia. We have confirmed elevated expression of GAD1 mRNA, but not of GAD2 mRNA, also in the rat lateral striatum. Image analysis favored the view that the regional increase is caused by elevated cellular expression, and that the greatest number of medium-sized spiny neurons were positive for GAD1 mRNA. The GAD1 mRNA distribution in the mouse lateral striatum partially resembled those of GPR155 and cannabinoid receptor type 1 mRNAs, suggesting functional cooperation in some neurons.
