    الوصف: Abstract The efficacy of immune checkpoint inhibitors (ICIs) has been widely recognized in several cancers and is now being used in the perioperative setting for lung cancer. We recently encountered an immune-related adverse event that has not been previously reported: thoracic lymphangitis, which occurred after postoperative ICI treatment for lung cancer. The patient complained of breathlessness and her condition rapidly progressed to hypoxia grade 3. Chest computed tomography revealed significant lymphostasis. With high-dose steroid treatment, the patient showed improvement. Therefore, as the frequency of neoadjuvant, adjuvant, and perioperative ICI use is expected to increase, it is crucial to understand and monitor this adverse event.

    الوصف: Abstract The efficacy of second-line chemotherapy in patients with pulmonary large cell neuroendocrine carcinoma (LCNEC) is unclear. This study aimed to evaluate the efficacy of second-line chemotherapy in patients with pulmonary LCNEC. We retrospectively reviewed patients with pulmonary LCNEC or possible LCNEC (pLCNEC) who received platinum-based chemotherapy as the first-line treatment. Among these patients, we evaluated the efficacy of second-line treatment by comparing patients with small cell lung cancer (SCLC group). Of the 61 patients with LCNEC or pLCNEC (LCNEC group) who received first-line chemotherapy, 39 patients were treated with second-line chemotherapy. Among the 39 patients, 61.5% received amrubicin monotherapy. The median progression-free survival (PFS) and overall survival (OS) in the LCNEC groups were 3.3 and 8.3 months, respectively. No significant differences in the PFS (hazard ratio [HR]: 0.924, 95% confidence interval [CI] 0.647–1.320; P = 0.664) and OS (HR: 0.926; 95% CI 0.648–1.321; P = 0.670) were observed between the LCNEC and SCLC groups. In patients treated with amrubicin, the PFS (P = 0.964) and OS (P = 0.544) were not different between both the groups. Second-line chemotherapy, including amrubicin, may be considered as a treatment option for patients with pulmonary LCNEC.

    الوصف: Abstract Background Which patients benefit from the addition of immune checkpoint inhibitors (ICIs) to chemotherapy for small cell lung cancer (SCLC) remains unclear. There have been few reports on the efficacy of ICIs based on conventional immunohistochemical neuroendocrine (NE) markers (synaptophysin, chromogranin A, and neural cell adhesion molecule [NCAM]). In the present study, we aimed to analyze the relationship between the expression of immunohistochemical NE markers and the efficacy of ICIs in patients with extensive disease (ED)‐SCLC, to assess whether conventional NE markers are predictive of ICIs. Methods Patients with untreated ED‐SCLC who received first‐line therapy at the Shizuoka Cancer Center between November 2002 and July 2021 were retrospectively reviewed. We evaluated the efficacy of first‐line chemotherapy according to the expression status of each immunohistochemical NE marker in patients treated with ICI plus chemotherapy (ICI‐chemo group) and with chemotherapy alone (chemo group). Results A total of 227 patients were included in the ICI‐chemo and chemo groups, respectively. The progression‐free survival (PFS) tended to be better in patients in the ICI‐chemo group than those treated with chemotherapy alone in patients with NE marker‐positive SCLC. In particular, it was statistically significant in patients with chromogranin A‐positive SCLC (p = 0.036). In patients with NE marker‐negative SCLC, no significant differences were observed in PFS between the two groups. There were no significant differences in overall survival (OS), regardless of the expression of any conventional NE marker. Conclusion Our study suggests that the efficacy of ICIs in addition to chemotherapy may be poor in patients with NE marker‐negative SCLC.

    الوصف: Abstract Background Amrubicin (AMR) regimens have shown efficacy as second‐line treatment in patients with small cell lung cancer (SCLC); however, adverse events such as febrile neutropenia (FN) sometimes preclude their use. Further, the safety and efficacy of AMR with primary prophylactic pegfilgrastim (P‐PEG) have not been sufficiently evaluated. In this study, we evaluated the safety and efficacy of AMR with or without P‐PEG as second‐line chemotherapy for SCLC. Methods We retrospectively reviewed patients with SCLC who received AMR as second‐line chemotherapy at Shizuoka Cancer Center, between December 2014 and November 2021. Based on presence/absence of P‐PEG in their regimen, patients (n = 60) were divided into P‐PEG (n = 21) and non‐P‐PEG groups, and their clinical outcomes were evaluated. Results Median of AMR treatment cycles was five (range: 1–39 cycles) in P‐PEG group and four (range: 1–15 cycles) in non‐P‐PEG group. The incidence of FN (4.8% vs. 30.8%; p = 0.02) and AMR dose reduction because of adverse events (4.8% vs. 25.6%; p = 0.08) were lower in the P‐PEG group than in the non‐P‐PEG group. The objective response rates were 52.4% and 30.8%, and median progression‐free and overall survival were 4.7 and 3.0 months, and 9.6 and 6.8 months, in the P‐PEG and non‐P‐PEG groups, respectively. Conclusions AMR with P‐PEG as second‐line chemotherapy for SCLC reduced the incidence of FN at a maintained AMR dose intensity and was associated with favorable tumor responses and survival outcomes. P‐PEG should be considered for patients treated with AMR for SCLC including refractory relapsed SCLC.

    الوصف: Abstract Carboplatin plus etoposide is a standard treatment for older extensive‐stage small‐cell lung cancer (ES‐SCLC) patients with performance status (PS) 2. However, older patients often exhibit poor PS (3, 4), and the treatment effect in them is poorly understood. To determine the therapeutic efficacy and safety of carboplatin plus etoposide therapy for this population, we retrospectively analyzed 63 patients with ES‐SCLC with PS ≥2, aged ≥71 years, who had received first‐line carboplatin plus etoposide therapy. We compared the treatment efficacy and safety in patients with baseline PS 2 versus those with PS 3–4. In the PS 2 (38 patients) and PS ≥3 (25 patients) groups, the overall response rate was 71.1% and 72.0%, median progression‐free survival was 4.6 and 3.1 months, and overall survival was 7.7 and 5.1 months, respectively. PS improved to 0–1 post‐treatment in 65.8% and 48.0% of the patients in the PS 2 and PS ≥3 groups, respectively. Patients with PS ≥3 showing improved PS had a progression‐free survival of 6.1 months. A higher incidence of grade ≥3 decreased neutrophil counts, febrile neutropenia, and treatment‐related death was observed in the PS ≥3 group. The progression‐free survival of patients administered prophylactic granulocyte colony‐stimulating factor (G‐CSF) was 5.2 and 6.1 months in the PS2 and PS ≥3 groups. Overall, carboplatin plus etoposide therapy provided comparable tumor shrinkage, but shorter progression‐free and overall survival in older ES‐SCLC patients with PS ≥3 than in those with PS 2. Thus, supportive care, such as prophylactic G‐CSF administration, may be necessary to ensure safety and survival.

    الوصف: Abstract Background Programmed cell death 1 (PD‐1)/programmed cell death ligand (PD‐L1) inhibitors plus chemotherapy (ICI + Chemo) is the standard treatment for advanced non‐small‐cell lung cancer (NSCLC). However, the impact of tumour burden on the efficacy of ICI + Chemo remains unknown. Methods We retrospectively evaluated 92 patients with advanced NSCLC treated with ICI + Chemo. Tumour burden was assessed as the sum of the longest diameter of the target lesion (BSLD) and number of metastatic lesions (BNMLs). We categorised the patients into three groups based on the combined BSLD and BNML values. Results Sixty‐eight patients (74%) had progressive disease or died. Forty‐four patients (48%) in the low‐BSLD group had a median progression‐free survival (PFS) of 9.5 months, whereas patients in the high‐BSLD group had a median PFS of 4.6 months (hazard ratio [HR] = 0.54, p = 0012). Twenty‐five patients (27%) in the low‐BNML group had a median PFS of 9.6 months, whereas patients in the high‐BNML group had a median PFS of 6.5 months (HR = 0.51, p = 0.029). Low‐BSLD and low‐BNML were associated independently with improved PFS in multivariate analysis. Analysis of the tumour burden combined with BSLD and BNML revealed a trend towards improved PFS as the tumour burden decreased, with median PFS of 22.3, 8.7, and 3.9 months in the low‐ (N = 13), medium‐ (N = 42) and high‐burden (N = 37) groups respectively. Conclusions Our findings demonstrated that a high tumour burden negatively impacts the efficacy of ICI + Chemo in patients with advanced NSCLC.

    الوصف: Abstract Background Cancer cachexia and tumor burden predict efficacies of programmed cell death‐1 (PD‐1)/programmed death‐ligand 1 (PD‐L1) inhibitors and chemotherapy or pembrolizumab in non‐small cell lung cancer (NSCLC). There are no predictive models that simultaneously assess cancer cachexia and tumor burden. Methods In the present retrospective study, we reviewed the medical records of patients with advanced NSCLC who received cancer immunotherapy as first‐line systemic therapy. Clinical immune predictive scores were defined according to multivariate analysis of progression‐free survival (PFS) and overall survival (OS). Results A total of 157 patients were included in the present study (75 treated with PD‐1/PD‐L1 inhibitors + chemotherapy; 82, pembrolizumab monotherapy). Multivariate analysis for PFS revealed that PD‐L1 tumor proportion scores

    الوصف: Abstract Background Adipose tissue induces inflammation, which desensitizes the efficacy of immunotherapy. However, several reports show that the therapeutic effect of programed cell death 1 (PD‐1)/programed death‐ligand 1 (PD‐L1) inhibitor(s) monotherapy is significantly better in obese patients. Therefore, the effect of adipose tissue on immunotherapy is unclear. Methods In this study, we retrospectively reviewed patients with advanced non‐small cell lung cancer (NSCLC) who received PD‐1/PD‐L1 inhibitor monotherapy between May 2016 and December 2018. We classified patients into total adipose tissue maintenance or loss groups according to adipose tissue change during the 6 months before treatment and compared the therapeutic effect of PD‐1/PD‐L1 inhibitors between these groups along with the presence or absence of cachexia, a poor prognostic factor. Results Of the 74 patients, 40 (54.1%) were cachexic. Among cachexic patients, we found no clear difference in the overall response rate (ORR) and progression‐free survival (PFS) between the total adipose tissue maintenance and loss group. However, among noncachexic patients, the total adipose tissue loss group had a higher ORR (64.7% vs. 23.5%, p

    الوصف: Purpose: This study aimed to clarify the characteristics of and evaluate the risk factors for radiation pneumonitis (RP) induced by chemoradiation therapy (CRT) using accelerated hyperfractionated (AHF) radiation therapy (RT) in patients with limited-stage small cell lung cancer (LS-SCLC). Methods and Materials: Between September 2002 and February 2018, 125 patients with LS-SCLC were treated with early concurrent CRT using AHF-RT. Chemotherapy was comprised of carboplatin/cisplatin with etoposide. RT was administered twice daily (45 Gy/30 fractions). We collected data regarding onset and treatment outcomes for RP, and analyzed the relationship between RP and total lung dose–volume histogram findings. Uni- and multivariate analyses were performed to assess patient- and treatment-related factors for grade ≥2 RP. Results: The median age of patients was 65 years, and 73.6% of participants were men. In addition, 20% and 80.0% of participants presented with disease stage II and III, respectively. The median follow-up time was 73.1 months. Grades 1, 2, and 3 RP were observed in 69, 17, and 12 patients, respectively. Grades 4 to 5 RP were not observed. RP was treated with corticosteroids in patients with grade ≥2 RP, without recurrence. The median time from initiation of RT to onset of RP was 147 days. Three patients developed RP within 59 days, 6 within 60 to 89 days, 16 within 90 to 119 days, 29 within 120 to 149 days, 24 within 150 to 179 days, and 20 within ≥180 days. Among the dose–volume histogram parameters, the percentage of lung volume receiving >30 Gy (V30) was most strongly related to the incidence of grade ≥2 RP, and the optimal threshold to predict RP incidence was V30 ≥20%. On multivariate analysis, V30 ≥20% was an independent risk factor for grade ≥2 RP. Conclusions: The incidence of grade ≥2 RP correlated strongly with a V30 of ≥20%. Contrarily, the onset of RP induced by concurrent CRT using AHF-RT may occur later. RP is manageable in patients with LS-SCLC.

    الوصف: Abstract Background Epidermal growth factor receptor tyrosine kinase inhibitors (EGFR‐TKIs) are currently the primary treatment option for patients with EGFR‐mutant non‐small cell lung cancer (NSCLC). However, the effect of EGFR‐TKIs are eventually weakened due to resistance, and there is also a differential efficacy based on EGFR mutation subtypes. The combination of angiogenesis inhibitor (AI) with EGFR‐TKI has shown better efficacy than EGFR‐TKI monotherapy, regardless of the mutation subtypes. Nevertheless, the effect of AI eligibility on overall survival (OS) and progression‐free survival (PFS) remains to be elucidated. Thus, we assessed this impact on patients with NSCLC harboring EGFR mutation. Methods In this study, the data for 450 patients with EGFR‐mutant NSCLC, who were treated with EGFR‐TKI monotherapy, were retrospectively analyzed for AI eligibility. The patients were categorized into AI‐eligible (AI fit) and ineligible groups (AI unfit). Results The median PFS of the AI fit group was 12.9 months, compared to 9.6 months in the unfit group (p = 0.007), and OS was also significantly longer in the AI fit group (median OS = 33.0 months) compared to that in the unfit group (18.5 months, p
