Condensed Matter - Abstract
In the plasma confinement type fusion reactor, in-vessel structures such as a blanket module slide at the joints each other when plasma disruption occurs, and then frictional heat is generated there. Therefore, for the selection of material and the use as the design data, it is important to understand the frictional characteristics of metals and ceramic films in the vacuum. In the present study, we have manufactured a prototype of rotary friction tester and examined the performances of the tester. The frictional characteristics of metals in the room air was measured using the friction tester, and the results obtained are as follows. A drifting friction force for a constant time and a friction force during the idling were 98 mN and 225 mN, respectively. These values were sufficiently small as compared to pressing load (9.8 - 57.8 N) used in the friction test. In a friction force measurement of stainless steel, dynamic friction force obeyed Amontons' law which indicated that dynamic friction force is not depend on either pressing load and sliding speed. The measured dynamic friction force of metals tended to decrease as the increasing hardness value of them, and it was maximum in aluminium. SEM observation of the surface for stainless steel and aluminium showed that the plastic flow was extensively generated in the mild metals during the friction test.

- Abstract
Objective:: To determine the preventive and curative effects of manual acupuncture on the symptoms of the common cold. Method:: Students and staff in five Japanese acupuncture schools (n=326) were randomly allocated to acupuncture and no-treatment control groups. A specific needling point (Y point) on the neck was used bilaterally. Fine acupuncture needles were gently manipulated for 15s, evoking de qi sensation. Acupuncture treatments were performed four times during the 2-week experimental period with a 2-week follow-up period. A common cold diary was scored daily for 4 weeks, and a common cold questionnaire was scored before each acupuncture treatment and twice at weekly intervals. A reliability test for the questionnaire was performed on the last day of recording. Results:: Five of the 326 subjects who were recruited dropped out. The diary score in the acupuncture group tended to decrease after treatment, but the difference between groups was not significant (Kaplan-Meier survival analysis, log rank test P=0.53, Cox regression analysis, P>0.05). Statistically significantly fewer symptoms were reported in the questionnaire by the acupuncture group than control group (P=0.024, general linear model, repeated measure). Significant inter-centre (P<0.001, general linear model) and sex (P=0.027, general linear model) differences were also detected. Reliability tests indicated that the questionnaire with 15 items was sufficiently reliable. No severe adverse event was reported. Conclusion:: This is the first report of a multi-centre randomized controlled trial of acupuncture for symptoms of the common cold. A significantly positive effect of acupuncture was demonstrated in the summed questionnaire data, although a highly significant inter-centre difference was observed. Needling on the neck using the Japanese fine needle manipulating technique was shown to be effective and safe. The use of acupuncture for symptoms of the common cold symptoms should be considered, although further evidence from placebo controlled RCTs is required.

- Abstract
Background: Cancer cachexia affects more than half of all cancer patients, reducing survival rates. Evidence-based approaches are urgently needed to optimize treatment., Methods: A systematic review and network meta-analysis were conducted to assess the effectiveness and safety of different pharmacotherapies for cancer cachexia. Three databases (PubMed, Cochrane Library, and Web of Science) were searched for the period from January 1, 2000, to March 20, 2024. The netmeta package in R software was used to calculate the pooled effect, employing a random effects model., Results: Seven placebo-controlled randomized trials involving 1421 patients were analyzed. Pairwise analysis showed that body weight increases were 4.6 kg (95% confidence interval [CI] 0.83-8.37 kg) for olanzapine, 3.82 kg (95% CI 0.73-6.91 kg) for espindolol (20 mg), 2.36 kg (95% CI 1.84-2.89 kg) for anamorelin (100 mg), and 1.31 kg (95% CI 0.42-2.19 kg) for anamorelin (50 mg). In terms of safety profiles, olanzapine demonstrated the lowest odds ratio when compared to placebo, at 0.26 (95% CI 0.07-0.94), followed by anamorelin (50 mg) at 0.86 (95% CI 0.30-2.48), and anamorelin (100 mg) at 0.89 (95% CI 0.42-1.88). However, network meta-analysis could not confirm the superiority of olanzapine over anamorelin in terms of efficacy and safety., Conclusion: Both olanzapine and anamorelin are useful in improving body weight in patients with cancer cachexia. Personalization may be helpful for different patients., (© 2024 The Author(s). Cancer Medicine published by John Wiley & Sons Ltd.)

- Abstract
Rationale: A fatal acute exacerbation (AE) occasionally develops during chemotherapy for small cell lung cancer (SCLC) with comorbid idiopathic pulmonary fibrosis (IPF). Objectives: This study aimed to assess the safety and efficacy of carboplatin, etoposide, and nintedanib combination therapy for unresectable SCLC with comorbid IPF. Methods: The NEXT-SHIP study is a multicenter, single-arm, phase 2 trial for unresectable SCLC with IPF (Japan Registry of Clinical Trials registry number jRCTs031190119). The patients received carboplatin, etoposide, and nintedanib (150 mg twice daily). The primary endpoint was the incidence of IPF-AE at 28 days after the last administration of cytotoxic chemotherapy, and the sample size was set at 33 (5.0% expected, 20.0% threshold). Results: A total of 33 patients were registered; 87.9% were male, the median age was 73 years, the median percentage forced vital capacity was 85.2%, and 51.5% had honeycomb lungs. The median observation period was 10.5 months. The incidence of IPF-AE at 28 days after the last administration of cytotoxic chemotherapy was 3.0% (90% confidence interval [CI], 0.2-13.6). The objective response rate was 68.8% (95% CI, 50.0-83.9). The median progression-free survival and overall survival times were 4.2 months (95% CI, 4.2-5.5) and 13.4 months (95% CI, 8.1-21.6), respectively. The most common adverse event of grade 3 or higher was neutropenia (81.8%), followed by leukopenia (39.4%) and thrombocytopenia (30.3%). Conclusions: This study met its primary endpoint regarding the incidence of IPF-AEs with promising results for efficacy. Carboplatin, etoposide, and nintedanib combination therapy may be one of the standard treatment options for SCLC with comorbid IPF.Clinical trial registered with the Japan Registry of Clinical Trials (jRCTs031190119).

- Abstract
Background: Central venous catheters (CVCs) are sometimes superior to peripheral vascular access for chemotherapy. Central line-associated bloodstream infections (CLABSIs) are an important complication of CVCs in chemotherapy., Methods: A retrospective, observational study was conducted to investigate patients with implanted venous access ports (PORTs) from July 2010 to June 2021 in a teaching hospital. General conditions of the PORTs, backgrounds, and characteristics of patients were compared between CLABSI cases and uninfected cases to identify predictors of CLABSI., Results: A total of 566 patients with PORTs who underwent chemotherapy were enrolled in this study, with CLABSI identified in 41 patients, for a total of 436,597 catheter-days. The median duration of PORT use was 26 vs . 494 days (P<0.001) in the CLABSI and uninfected groups, respectively. There were no significant differences in tumor classification, staging, white blood cell (WBC) count, neutrophil proportion, lymphocyte proportion, albumin, C-reactive protein (CRP), and performance status between the CLABSI and uninfected groups. Multivariable analysis showed that antibiotic usage within the previous week, total protein (TP), and immediate PORT use were independently associated with CLABSI, and their odds ratios (ORs) were 4.89 [95% confidence interval (CI): 1.67, 14.35], 1.95 (95% CI: 1.14, 3.53), and 3.13 (95% CI: 1.18, 8.30), respectively. The area under the curve (AUC) of the receiver-operating characteristic curve for TP was 0.63, and the cutoff value was 5.9 g/dL., Conclusions: PORT implantation should be avoided in patients who had antibiotic treatment episodes within 1 week, especially for those with low serum TP levels., Competing Interests: Conflicts of Interest: All authors have completed the ICMJE uniform disclosure form (available at https://tcr.amegroups.com/article/view/10.21037/tcr-23-1217/coif).

- Abstract
Introduction: Necitumumab plus gemcitabine and cisplatin (GCN) is a standard therapy for patients with advanced lung squamous cell carcinoma (LSqCC). However, the efficacy and tolerability of GCN in second-line or later treatment for patients previously treated with immune checkpoint inhibitors (ICIs) remain unknown., Methods: This multicenter, retrospective, cohort study assessed the efficacy and tolerability of GCN initiated between November 1, 2019 and March 31, 2022 as second-line to fourth-line treatment in patients with advanced LSqCC who had been pretreated with ICIs. The primary end point was progression-free survival (PFS)., Results: A total of 93 patients from 35 institutions in Japan were enrolled. The median PFS, median overall survival (OS), and objective response rate were 4.4 months (95% confidence interval [CI]: 3.8-5.3), 13.3 months (95% CI: 9.6-16.5), and 27.3% (95% CI: 18.3-37.8), respectively. The median PFS, median OS, and objective response rate for second-line, third-line, and fourth-line treatment groups were 4.8 months, 3.8 months, and 4.3 months ( p = 0.24); 15.7 months, 11.6 months, and 10.1 months ( p = 0.06); and 31.0%, 13.6%, and 37.5% ( p = 0.22), respectively. The severity of GCN-related skin disorders was associated with longer PFS ( p < 0.05) and OS ( p < 0.05). The frequencies of grade ≥3 skin disorders, hypomagnesemia, pneumonitis, and febrile neutropenia were 16.1%, 7.5%, 1.1%, and 4.3%, respectively. There were no treatment-related deaths., Conclusions: GCN for ICI-pretreated patients with LSqCC seems tolerable and offers promising efficacy regardless of treatment line, and ICI pretreatment might enhance GCN efficacy., (© 2023 The Authors.)

- Abstract
Background: Dacomitinib significantly improves progression-free survival and overall survival (OS) compared with gefitinib in patients with non-small-cell lung cancer (NSCLC) harboring epidermal growth factor receptor (EGFR)-activating mutations. However, dacomitinib often causes skin toxicities, resulting in treatment discontinuation. We aimed to evaluate a prophylactic strategy for skin toxicity induced by dacomitinib., Methods: We performed a single-arm, prospective, open-label, multi-institutional phase II trial for comprehensive skin toxicity prophylaxis. Patients with NSCLC harboring EGFR-activating mutations were enrolled and received dacomitinib with comprehensive prophylaxis. The primary endpoint was the incidence of skin toxicity (Grade ≥2) in the initial 8 weeks., Results: In total, 41 Japanese patients participated between May 2019 and April 2021 from 14 institutions (median age 70 years; range: 32-83 years), 20 were male, and 36 had a performance status of 0-1. Nineteen patients had exon 19 deletions and L858R mutation. More than 90% of patients were perfectly compliant with prophylactic minocycline administration. Skin toxicities (Grade ≥2) occurred in 43.9% of patients (90% confidence interval [CI], 31.2%-56.7%). The most frequent skin toxicity was acneiform rash in 11 patients (26.8%), followed by paronychia in five patients (12.2%). Due to skin toxicities, eight patients (19.5%) received reduced doses of dacomitinib. The median progression-free survival was 6.8 months (95% CI, 4.0-8.6 months) and median OS was 21.6 months (95% CI, 17.0 months-not reached)., Conclusion: Although the prophylactic strategy was ineffective, the adherence to prophylactic medication was quite good. Patient education regarding prophylaxis is important and can lead to improved treatment continuity., (© 2023 The Authors. Cancer Medicine published by John Wiley & Sons Ltd.)

- Abstract
Objectives: This study aimed to determine the inhibitory and bactericidal effects of teicoplanin (TEC) on TEC-susceptible Staphylococcus haemolyticus isolated from a patient with cancer in whom infection persisted despite TEC therapy. We also focused on the biofilm-forming ability of the isolate in vitro., Methods: S. haemolyticus clinical isolate (strain 1369A) and its control strain, ATCC 29970 were cultured in Luria-Bertani (LB) broth with TEC. The inhibitory and bactericidal effects of TEC on planktonic, adherent, biofilm-dispersed, and biofilm-embedded cells of these strains were analyzed by using a biofilm formation/viability assay kit. The expression of biofilm-related genes was measured using quantitative real-time polymerase chain reaction (qRT-PCR). Biofilm formation was determined by using scanning electron microscopy (SEM)., Results: The clinical isolate of S. haemolyticus had enhanced ability to bacterial growth, adherence, aggregation, and biofilm formation, thus the inhibitory and bactericidal effects of TEC on planktonic, adherent, biofilm-dispersed, and biofilm-embedded cells of the isolate were attenuated. Additionally, TEC induced cell aggregation, biofilm formation, and some biofilm-related gene expression of the isolate., Conclusion: The clinical isolate of S. haemolyticus is resistant to TEC treatment due to cell aggregation and biofilm formation., Competing Interests: Declaration of competing interest The authors declare the following financial interests/personal relationships which may be considered as potential competing interests: Yoshinori Sato reports financial support was provided by JSPS KAKENHI.

- Abstract
Background: Ramucirumab plus docetaxel combination therapy (DOC/RAM) for advanced non-small cell lung cancer (NSCLC) achieves favorable outcomes; however, efficacy and safety for patients with brain metastases are still unclear., Methods: Eligible patients included those with advanced NSCLC with measurable asymptomatic brain metastases that progressed after chemotherapy. Patients were intravenously administered ramucirumab (10 mg/kg) and docetaxel (60 mg/m2) every 21-day cycle., Results: Due to difficulties in accumulating the planned 65 participants, enrollment was terminated early when 25 patients were enrolled. Primary endpoint: Median progression-free survival (PFS) was 3.9 months (95% CI, 1.8-5.3). Secondary endpoints: Median intracranial progression-free survival was 4.6 months (95% CI, 2.5-5.9); median overall survival was 20.9 months (95% CI, 6.6-not possible to estimate); objective response rate was 20% (95% CI, 6.8-40.7); disease control rate was 68% (95% CI, 46.5-85.1). The most common grade 3 or higher toxicities were neutropenia in 10 patients (40%). Neither intracranial hemorrhage nor grade 5 adverse events were observed. Patients with higher serum soluble vascular endothelial growth factor receptor 2 concentrations at the start of treatment had slightly longer PFS., Conclusion: No clinical concerns were identified with DOC/RAM for NSCLC with brain metastases in this study. Further investigation with a larger sample size is needed to determine the tolerability and safety of these populations (Trial Identifiers: University Hospital Medical Information Network in Japan [UMIN000024551] and Japan Registry of Clinical Trials [jRCTs071180048])., (© The Author(s) 2023.

- Abstract
Background: The standard of care for unresectable, locally advanced non-small-cell lung cancer (LA-NSCLC) is chemoradiotherapy (CRT) followed by durvalumab, based on the PACIFIC study. Although multiple Japanese phase II studies have shown high efficacy and tolerability of CRT with cisplatin plus S-1 (SP), no prospective study using durvalumab after SP-based CRT has been reported., Objectives: We conducted a multicenter phase II study of this approach, the interim analysis of which showed a high transition rate to durvalumab consolidation therapy. Here, we report the primary analysis results., Design: In treatment-naïve LA-NSCLC, cisplatin (60 mg/m
2 , day 1) and S-1 (80-120 mg/body, days 1-14) were administered with two 4-week cycles with concurrent thoracic radiotherapy (60 Gy) followed by durvalumab (10 mg/kg) every 2 weeks for up to 1 year., Methods: The primary endpoint was 1-year progression-free survival (PFS). The expected 1-year PFS and its lower limit of the 80% confidence interval (CI) were set as 63% and 47%, respectively, based on the results of TORG1018 study., Results: In all, 59 patients were enrolled, with 51 (86.4%) proceeding to durvalumab. The objective response rate throughout the study was 72.9% (95% CI: 59.7-83.6%). After median follow-up of 21.9 months, neither median PFS nor OS was reached. The 1-year PFS was 72.5% (80% CI: 64.2-79.2%, 95% CI: 59.1-82.2%), while the 1-year overall survival was 91.5% (95% CI: 80.8-96.4%). No grade 5 adverse events were observed throughout the study. The most common adverse event during the consolidation phase was pneumonitis (any grade, 78.4%; grade ⩾3, 2.0%). Eventually, 52.5% of patients completed 1-year durvalumab consolidation therapy from CRT initiation., Conclusion: This study of durvalumab after SP-based CRT met its primary endpoint and found a 1-year PFS of 73% from CRT initiation. This study provides the first prospective data on the prognosis and tolerability of durvalumab consolidation from the initiation of CRT., Trial Registration: Japan Registry of Clinical Trials, jRCTs031190127, registered 1 November, 2019, https://jrct.niph.go.jp/latest-detail/jRCTs031190127., Competing Interests: H.T. received personal fees as honoraria from Boehringer Ingelheim, AstraZeneca, Pfizer, Chugai Pharmaceutical, Bristol-Myers Squibb, and Ono Pharmaceutical.

- Abstract
Background: Osimertinib is one of the standard first-line treatments for advanced non-small cell lung cancer in patients with epidermal growth factor receptor (EGFR) mutations, because it achieves significantly longer progression-free survival (PFS) than conventional first-line treatments (hazard ratio: 0.46). However, the efficacy and safety of osimertinib as a first-line treatment for patients aged ≥75 years remain unclear., Methods: This phase II study was performed to prospectively investigate the efficacy and safety of osimertinib for elderly patients with EGFR mutation-positive advanced non-small cell lung cancer. The primary endpoint was 1-year PFS rate; secondary endpoints were overall response rate (ORR), PFS, overall survival (OS), and safety., Results: Thirty-eight patients were included in the analysis. The 1-year PFS rate was 59.4% (95% confidence interval [CI], 46.1%-72.7%), which did not meet the primary endpoint (the threshold 1-year PFS rate of 50% predicted using data from the NEJ003 study). The most common grade 3/4 adverse events were rash/dermatitis acneiform/ALT increased/hypokalemia (2 patients, 5%). Seven patients developed pneumonitis (17.5%). There were no other cases of treatment discontinuation due to adverse events other than pneumonitis., Conclusion: Although this study did not meet the primary endpoint, osimertinib was tolerable for elderly patients with EGFR mutation-positive advanced non-small cell lung cancer.

- Abstract
Background: The standard of care for unresectable, locally advanced non-small cell lung cancer (LA-NSCLC) is chemoradiotherapy (CRT) followed by durvalumab, based on the PACIFIC trial. Disease progression and pneumonitis were reported as the main reasons to preclude the initiation of durvalumab in multiple retrospective studies. However, the transition rate and the reasons for failure to proceed to consolidation therapy with durvalumab after CRT were not evaluated prospectively. Although phase II studies in Japan have shown high efficacy and tolerability of CRT with cisplatin + S-1 (SP), no prospective study using durvalumab after SP-based CRT has yet been reported. We therefore conducted a phase II study to verify the efficacy and safety of durvalumab following SP-based CRT. In this interim analysis, we report the transition rate and the reasons for its failure., Methods: In treatment-naïve LA-NSCLC, cisplatin (60 mg/m
2 , day 1) and S-1 (80-120 mg/body, days 1-14) were administered with two 4-week cycles with concurrent thoracic radiotherapy (60 Gy) followed by durvalumab every 2 weeks for up to 12 months. The primary endpoint was 12 month progression-free survival rate., Results: Fifty-nine patients were enrolled, of whom 86.4% (51/59) proceeded to durvalumab. All of them initiated durvalumab within 42 days after CRT [median 18 days (range: 3-38)], including 27.5% (14/51) in <14 days. Common reasons for failure to proceed to durvalumab were disease progression (2/59, 3.4%) and adverse events (6/59, 10.2%). Among the latter cases, four resumed treatment and proceeded to durvalumab within 42 days on off-protocol. The objective response rate and the disease control rate were 62.7% and 93.2%, respectively. The incidences of ⩾grade 3 pneumonitis, febrile neutropenia, and esophagitis were 0%, 8.5%, and 3.4%, respectively., Conclusion: Regarding durvalumab after CRT, this interim analysis of the SAMURAI study clarified the high transition rate, early introduction, and reasons for failure to proceed to consolidation therapy, which were not determined in the PACIFIC trial., Trial Registration: Japan Registry of Clinical Trials, jRCTs031190127, registered 1 November, 2019, https://jrct.niph.go.jp/latest-detail/jRCTs031190127., Competing Interests: Competing Interests: ST received research funding from AstraZeneca and personal fees as honoraria from AstraZeneca, Chugai Pharmaceutical, Taiho Pharmaceutical, and Eli Lilly.

- Abstract
Background: Pulmonary large cell neuroendocrine carcinoma (LCNEC) is a rare subset of lung carcinoma with poor overall survival., Methods: A systematic review following a meta-analysis of studies was performed to identify the effect of different selections of chemotherapy in LCNEC. Articles providing overall survival data for adjuvant chemotherapy or palliative chemotherapy for LCNEC were eligible. The odds ratio (OR) of mortality at one or two years after chemotherapy was evaluated., Results: A total of 16 reports were finally included in the quantitative synthesis, involving a total of 5916 LCNEC patients. Adjuvant chemotherapy was administered to 1303 patients, and palliative chemotherapy was administered to 313 patients using either a small cell lung cancer (SCLC) or a non-small cell lung cancer (NSCLC) regimen. The OR for adjuvant chemotherapy was 0.73 (95% confidence interval (CI): 0.59 to 0.89, p = 0.002). The SCLC regimen showed an OR of 0.52 (95% CI: 0.11 to 2.38, p = 0.40) after one year, and 0.32 (95% CI: 0.11 to 0.89, p = 0.03) after two years, compared with the NSCLC regimen., Conclusions: Adjuvant chemotherapy for pulmonary large cell neuroendocrine carcinoma improved the outcome after surgery. The SCLC regimen showed better survival than the NSCLC regimen as palliative chemotherapy.

- Abstract
Background: Malignancy-related ascites (MRA) is one of the symptoms causing discomfort in advanced cancer patients. Cell-free and concentrated ascites reinfusion therapy (CART) is one of the palliative treatments widely conducted in Japan only., Methods: A systematic review following a meta-analysis of CART was performed. The efficiency and adverse events were evaluated., Results: A total of 2567 patients and 6013 procedures of CART were identified in this study. The mean volume of MRA collected was 4.29 (95% confidence interval (CI) 3.47-5.11) L, and the volume reinfused after concentrating was 0.49 (95% CI 0.39-0.60) L. A total of 86.1 (95% CI 77.1-95.2) g protein and 42.9 (95% CI 36.0-50.0) g albumin was reinfused. The mean time to the next paracentesis was 20.7 (95% CI 15.6-25.8) days. The body weight was reduced by 3.38 (95% CI 1.90-4.86; p < 0.01) kg, and abdominal circumference was reduced by 7.86 (95% CI 6.58-9.14; p < 0.001) cm. Serum albumin increased an average of 0.14 (95% CI -0.01-0.28; p = 0.07) mg/dL the day after CART. Abdominal distension, dyspnea, and fatigue were alleviated by 6.0 (95% CI 5.59-6.51), 2.66 (95% CI 2.05-3.28), and 2.64 (95% CI 1.86-3.42) points using a numerical rating scale system ranging from 0 to 10. Overall, 17% (95% CI 0.03-0.31%) of patients had improved performance status after CART. Significant body temperature elevation was observed, at an average of 0.4 °C (95% CI 0.18-0.62 °C)., Conclusions: CART might be a safe and effective palliative therapy in MRA and further clinical trials are necessary.

- Abstract
As a treatment strategy for various carcinoma, immune checkpoint inhibitors(ICIs)can prolong overall survival with ICI monotherapy, ICIs combination therapy, or chemotherapy and ICI combination therapy. It has been validated in clinical trials and is recognized as a key drug in the treatment of cancer. In two large phase Ⅲ trials(IMpower133 and CASPIAN), the strategy of anti PD‒L1 antibody, such as atezolizumab and durvalumab, with chemotherapy was prolonged overall survival compared with the chemotherapy alone in extensive stage small cell lung cancer. Although attention should be paid to immune‒related adverse events, treatment discontinuation rates for adverse events in both trials were considered to be comparable to those in the chemotherapy alone group, indicating that treatment was tolerated. Currently, carboplatin plus etoposide plus atezolizumab combination therapy or platinum agent(carboplatin or cisplatin)plus etoposide plus durvalumab combination therapy is recommended grade 1A in the Guidelines for Diagnosis and Treatment of the Lung Cancer/ Malignant Pleural Mesothelioma/Thymic Tumors 2020 as the first‒line treatment for extensive stage small cell lung cancer in Japan. This article presents an overview of each clinical trials and clinical questions.

- Abstract
Background: Atezolizumab is a programmed death-ligand 1 (PD-L1) targeted monoclonal antibody that inhibits PD-L1 interacting with its receptors PD-1 and B7-1, thereby enhancing anticancer immunity. Some real-world efficacy and safety studies of anti-PD-1 antibody have been previously reported. However, there have been no reports investigating the efficacy of atezolizumab monotherapy in clinical practice which have focused on performance status and previous anti-PD-1 antibody treatment., Methods: We retrospectively reviewed consecutive advanced NSCLC patients who received atezolizumab monotherapy between April 2018 and February 2019 at eight institutions. A total of 152 patients with NSCLC were enrolled in this study., Results: A total of 38 patients (25%) had already been treated with anti-PD-1 treatment (nivolumab or pembrolizumab) before atezolizumab. The median OS and TTF was 384 days (12.8 months) (95% confidence interval [CI]: 206-424), and 42 days (1.4 months) (95% CI: 27-56) in all patients, respectively. ECOG PS 0 had significantly longer OS (median OS; not reached, p < 0.0001) and TTF (median TTF; 63 days, p = 0.012) compared with PS 1 or 2-3. Most retreated patients were unable to continue atezolizumab for a longer period, but seven patients (18.4%) were able to continue atezolizumab over four months as an ICI retreatment., Conclusions: In previously treated advanced NSCLC patients, atezolizumab monotherapy demonstrated good efficacy and safety regardless of heavily treated patients in real-world clinical practice, and ECOG PS 0 was a favorable predictive factor. The efficacy of retreatment with atezolizumab was limited but was well tolerated in patients treated with prior anti-PD-1 antibody., (© 2021 The Authors.

- Abstract
Background: Based on the results of the PACIFIC study, chemoradiotherapy followed by 1-year consolidation therapy with durvalumab was established as the standard of care for unresectable, locally advanced non-small-cell lung cancer (LA-NSCLC). However, some topics not foreseen in that design can be explored, including progression-free survival (PFS) and overall survival (OS) after the start of chemoradiotherapy, the proportion of patients who proceeded to consolidation therapy with durvalumab, and the optimal chemotherapeutic regimens. In Japan, the combination regimen of S-1 + cisplatin (SP), for which the results of multiple clinical studies have suggested a good balance of efficacy and tolerability, is frequently selected in clinical settings. However, the efficacy and safety of consolidation therapy with durvalumab following this SP regimen have not been evaluated. We therefore planned a multicenter, prospective, single-arm, phase II study., Methods: In treatment-naïve LA-NSCLC, two cycles of combination chemotherapy with S-1 (80-120 mg/body, Days 1-14) + cisplatin (60 mg/m
2 , Day 1) will be administered at an interval of 4 weeks, with concurrent thoracic radiotherapy (60 Gy). Responders will then receive durvalumab every 2 weeks for up to 1 year. The primary endpoint is 1-year PFS rate., Discussion: Compared with the conventional standard regimen in Japan, the SP regimen is expected to be associated with lower incidences of pneumonitis, esophagitis, and febrile neutropenia, which complicate the initiation of consolidation therapy with durvalumab, and have higher antitumor efficacy during chemoradiotherapy. Therefore, SP-based chemoradiotherapy is expected to be successfully followed by consolidation therapy with durvalumab in more patients, resulting in prolonged PFS and OS. Toxicity and efficacy results of the SP regimen in this study will also provide information important to the future establishment of the concurrent combination of chemoradiotherapy and durvalumab., Trial Registration: Japan Registry of Clinical Trials, jRCTs031190127, registered 1 November 2019, https://jrct.niph.go.jp/latest-detail/jRCTs031190127., Competing Interests: Conflict of interest statement: S.T. received research funding from AstraZeneca K.K.

- Abstract
Background: Neutrophil-to-lymphocyte ratio (NLR) has recently attracted attention as a prognostic predictor in patients with non-small cell lung cancer (NSCLC) who receive immune checkpoint inhibitors (ICIs). However, the utility of NLR in relation to cytotoxic anticancer drugs or molecular targeted drugs remains unclear. We determined if NLR could predict the treatment efficacy and prognosis in NSCLC patients who receive cytotoxic anticancer drugs or molecular targeted drugs, as well as ICIs, in a cross-sectional manner., Methods: Of 658 patients with advanced NSCLC who received first-line systemic treatment in our hospital between 2008 and 2019, 312 who met the analytical criteria were included in the study. We retrospectively analyzed the ability of NLR with a cut-off value of 5 to predict time to treatment failure (TTF) and overall survival (OS) in patients who received the following treatments: first-line treatment with molecular targeted drugs (mt group, n=100); first-line treatment with cytotoxic anticancer drugs (wt group, n=212); and first-line treatment with cytotoxic anticancer drugs followed by ICIs (ICI group, n=58)., Results: In the high- and low-NLR mt subgroups, median TTFs were 6.7 and 14.9 months (P<0.01), respectively, and median survival times (MSTs) were 17.8 and 39.1 months (P<0.01), respectively. In the high- and low-NLR wt subgroups, median TTFs were 1.5 and 5.8 months (P<0.01), and MSTs were 6.3 and 20.7 months (P<0.01), respectively. In the high- and low-NLR ICI subgroups, median TTFs were 1.3 and 6.8 months (P<0.01), and MSTs were 9.2 and 25.8 months (P<0.01), respectively. Multivariate analysis identified NLR as a significant independent predictor of TTF [hazard ratio (HR) 1.89, P=0.01; HR 2.51, P<0.01; and HR 5.06, P<0.01 in the mt, wt, and ICI groups, respectively) and OS (HR 3.81, P<0.01; HR 2.59, P<0.01; and HR 2.48, P<0.01, respectively)., Conclusions: This study showed that NLR might be a predictor of treatment efficacy and prognosis in advanced NSCLC patients who receive various systemic treatments. This finding of consistent applicability of NLR to a wide variety of systemic treatments is of great significance., Competing Interests: Conflicts of Interest: All authors have completed the ICMJE uniform disclosure form (available at http://dx.doi.org/10.21037/tlcr-20-777).

- Abstract
We herein report a case of breast cancer in a 74-year-old woman treated with exemestane as fourth-line hormonal therapy and bone-modifying agents for long time. She suddenly developed a right femoral shaft fracture during treatment. Her femoral fracture had a beaking sign on radiogram. Given this finding, her fracture was ultimately diagnosed as atypical femoral fracture (AFF). In this case, it was difficult to recognize the difference between groin pain as a prodromal symptom of AFF and that due to an adverse reaction to hormonal therapy. Therefore, clinicians should recognize the difficulty of this differentiation and consider the situation with caution.

- Abstract
Common dermatological side-effects associated with erlotinib, epidermal growth factor receptor (EGFR) tyrosine kinase inhibitor (TKI), include pruritus and skin rash, which are mediated by substance P, leading to the occasional discontinuation of cancer treatment. Aprepitant is an antagonist of neurokinin-1 receptor, through which substance P activates the pruritogens. Thus, aprepitant is expected to offer a promising option for the treatment of erlotinib-induced pruritus. However, the appropriate treatment schedule for aprepitant administration is under consideration. Here, we discuss the need for flexible adjustment of the treatment schedule for aprepitant administration against erlotinib-induced refractory pruritus and skin rush. A 71-year-old female smoker presented with stage IV EGFR-mutated lung adenocarcinoma. She was started on erlotinib at 150 mg/day. However, by 28 days, severe pruritus and acneiform skin rush resistant to standard therapies occurred, resulting in the interruption of erlotinib therapy. After recovery, she was restarted on erlotinib at 100 mg/day. However, severe pruritus and skin rush developed again within 2 weeks. Then, we started the first 3-day dose of aprepitant (125 mg on day 1, 80 mg on day 3, and 80 mg on day 5) based on the results of the previous prospective study, which showed the success rate of 100% with at least the second dose of aprepitant. However, the pruritus and skin rush exacerbated again within 4 weeks. Therefore, we started the second 3-day dose of aprepitant, but in vain. At this point, as the patient-centered medicine, bi-weekly schedule of the 3-day dose of aprepitant was considered and, then, adopted. As the results, the pruritus and skin rush remained well-controlled throughout the subsequent treatment with erlotinib.

- Abstract
In lung cancer, several potential mechanisms of intrinsic and acquired resistance to epidermal growth factor receptor (EGFR) tyrosine kinase inhibitors (TKIs) have been explored, including mesenchymal-epithelial transition factor (MET) signaling pathway activation. On the other hand, vascular endothelial growth factor (VEGF) production of EGFR-mutated lung cancer cells is stimulated by predominantly activated MET signaling pathway. Therefore, the inhibition of VEGF axis as the downstream target of MET signaling pathway seems promising. Here, for the first time, we report the potential efficacy of combination therapy with bevacizumab and erlotinib in an EGFR-mutated NSCLC patient with MET amplification who showed intrinsic resistance to initial EGFR-TKI therapy. The patient was a 60-year-old male smoker, showing performance status (PS) 2, who presented with stage IV lung adenocarcinoma (cT4N2M1a) harboring the EGFR exon 19 deletion mutation. He was started on gefitinib at 250 mg/day. However, by 28 days, his symptoms further deteriorated along with the increased tumor size, resulting in PS 3. Then, repeat biopsy was performed, showing the positive MET amplification and the preserved EGFR exon 19 deletion mutation. Therefore, on the basis of the potential efficacy for activated MET signaling pathway as well as the confirmed safety by the known phase II trial for EGFR-mutated patients, the patient was started on combination therapy with bevacizumab at 15 mg/kg every 3 weeks plus erlotinib at 150 mg/day. By 21 days, his symptoms gradually improved along with the decreased tumor size, resulting in better PS with no severe toxicities.

- Abstract
For sebaceous carcinoma (SC), a rare malignant tumor, no standard chemotherapy regimen for patients with distant metastasis has been studied. We experienced a case of eyelid SC with multiple lung metastases that responded to combination chemotherapy with carboplatin and paclitaxel with 11-month progression-free survival (PFS). This patient also responded to second-line treatment with docetaxel, another taxane, with 7-month PFS, resulting in at least 18 months of survival at the time of reporting. This report shows that taxane-based chemotherapy may be effective for advanced SC, for which no standard therapy has been established.

- Abstract
We encountered a case of primary lung cancer complicated with membranous nephropathy as primary nephrotic syndrome. Because treatment approaches vary greatly for primary and secondary nephrotic syndrome, a renal biopsy was performed for diagnosis. Much time was required to make a definitive diagnosis of primary nephrotic syndrome, as opposed to paraneoplastic nephrotic syndrome. Consequently, the subsequent chemotherapy was ineffective and caused significant toxicity due to reduced performance status (PS) and progression of hypoalbuminemia. Therefore, it is imperative that a diagnosis be made and treatment be initiated without delay before PS declines and hypoalbuminemia progresses.

- Abstract
A 50-year-old man with lung adenocarcinoma (c-T1aN2M1b) experienced reddish purpura mainly on the lower legs after receiving 12 cycles of second-line chemotherapy with docetaxel. There was tumor enlargement on computed tomography performed to assess the therapeutic response, so paraneoplastic IgA vasculitis was considered. IgA vasculitis was diagnosed based on a biopsy of the skin lesion and histology of an upper gastrointestinal hemorrhagic mucosal erosion. As IgA vasculitis can lead to serious gastrointestinal or systemic complications, IgA vasculitis should be considered as a differential diagnosis for rashes in patients with malignancy.

- Abstract
The patient was a 66-year-old woman. An induration of approximately 15 mm in size that accompanied redness was palpable in the umbilical fossa. She did not respond to 1-month antibiotic treatment provided by the previous physician. For this reason, a biopsy of the site was performed with the possibility of neoplastic disease in mind, resulting in the detection of adenocarcinoma. Subsequent detailed whole-body examination revealed advanced gastric cancer and peritoneal dissemination, and the induration in the umbilical fossa was diagnosed as a direct infiltration from the peritoneal dissemination. Metastasis or infiltration of malignant tumor to the umbilicus is called Sister Mary Joseph's nodule (SMJN), and considered as a sign of poor prognosis. However, this case was successfully treated and achieved a long-term prognosis by the early diagnosis of SMJN. In routine clinical practice, it is considered necessary to examine patients carefully, as not to overlook SMJN.

- Abstract
A 73-year-old man, followed for prostatic hyperplasia, developed submandibular gland cancer. Initially, because of the concurrent presence of elevated serum prostate-specific antigen (PSA) and multiple bone metastases, he was clinically determined as having stage IV prostate cancer in addition to stage II submandibular gland cancer, and radical surgery for his submandibular gland cancer was performed first. However, subsequent detailed examinations of the prostate gland showed no prostate cancer, and a diagnosis of advanced submandibular gland cancer with increased PSA and multiple bone metastases was established. Serum PSA is highly specific for prostate diseases and is widely used as a tumor marker of prostate cancer. However, clinicians should be aware that, in patients with non-prostate cancer, the detection of increased PSA and multiple bone metastases does not necessarily indicate the concurrent presence of prostate cancer.

- Abstract
The patient was a 69-year-old male who had started experiencing acute-onset pain in both shoulder joints and edema of both hands and feet. His symptoms progressively worsened within 1 month. Laboratory data indicated elevated CRP and erythrocyte sedimentation rate despite the normal range of antinuclear antibodies and rheumatoid factor and normal organ function. Furthermore, imaging data of the hand indicated synovitis without bone erosions. Meanwhile, chest CT revealed a lung tumor, leading to a diagnosis of primary lung adenocarcinoma with EGFR mutation (cT2aN3M0, stage IIIB). Based on these findings, he was diagnosed as suffering from paraneoplastic remitting seronegative symmetrical synovitis with pitting edema (RS3PE) syndrome. Thereafter, his symptoms disappeared as the tumor size was rapidly decreased by gefitinib therapy for lung adenocarcinoma. Currently, RS3PE syndrome can be classified as a vascular endothelial growth factor (VEGF)-associated disorder. Given that his symptoms improved by chemotherapy, the present case further supported the possible hypothesis that paraneoplastic RS3PE syndrome might be caused by tumor-induced VEGF. Therefore, the present case suggested that the symptoms of acute-onset joint pain accompanied by pitting edema in elderly patients should be considered suspicious for a malignant tumor, thereby warranting a detailed full-body examination.

- Abstract
A 40-year-old man with a diagnosis of lung adenocarcinoma (cT4N3M1c, stage IVB) experienced worsening of lymphangitic carcinomatosis in the right lung and right pleural effusion after receiving 1 cycle of first-line chemotherapy consisting of cisplatin and pemetrexed. Bevacizumab was thus added from the second cycle of the cisplatin-pemetrexed regimen, leading to a marked improvement in pulmonary lymphangitic carcinomatosis and a decrease in pleural effusion. Subsequently, maintenance therapy consisting of pemetrexed and bevacizumab was continued, successfully leading to long-term progression-free survival. Generally, pulmonary lymphangitic carcinomatosis shows poor prognosis because of poor response to chemotherapy. However, recent studies have been elucidating the role of the vascular endothelial growth factor A (VEGF-A)/VEGF receptor-2 pathway in pulmonary lymphangitic carcinomatosis. Therefore, bevacizumab is expected to be beneficial in the treatment of this pathological condition.

- Abstract
We report a hemodialysis patient with extensive small-cell lung cancer who was administered CPT-11(50mg/m2)chemotherapy and achieved a partial response after four courses of chemotherapy. Hemodialysis was performed 24 hours after the first course of CPT-11 was completed. Because the patient developed thrombocytopenia and pneumonia, hemodialysis was performed 4 hours following the second course of chemotherapy, after which grade III bone marrow suppression was observed. The plasma concentrations of CPT-11 and its metabolic products(SN-38 and SN-38G)were measured during both courses. A pharmacokinetic study showed that the plasma concentration of CPT-11 after the first course was relatively high, and that the kinetics was similar to that in a non-dialysis case. However, 4 hours after hemodialysis, the concentrations of CPT-11 and SN-38G were re-elevated, and showed a sustained level higher than that obtained 24 hours after hemodialysis. Further study is needed to determine the optimal dosages of CPT-11, and the best time to conduct hemodialysis for chronic cancer patients requiring it.

- Abstract
We summarize the results from a series of investigations of Japanese style acupuncture and moxibustion therapies on symptoms of the common cold that have been conducted (FTLE 1999-03, supported by the Foundation for Training and Licensure Examination in Anma- Massage- Acupressure, Acupuncture and Moxibustion). We also discuss the various interventions and concerns that we faced during these investigations. The subjects were students and teachers. The pilot study (FTLE1999) of a two arm (real and non-treatment control) RCT at a Japanese acupuncture school showed that manual acupuncture to a specific needling point at the throat clearly reduced symptoms of the common cold. The first multi-center (five centers) RCT (FTLE 2000) revealed a significant reduction in cold symptoms, by general linear model analysis (between groups, P = 0.024). To reduce the technical variation, we employed indirect moxibustion to the neck points as a uniform intervention in the next project (FTLE 2001) without statistically significant results. Then we elongated the periods of treatment from 2 to a maximum of 12 weeks (FTLE 2002) with different interventions accompanied by 4 weeks follow-up. The results were still not statistically significant. As the final project, we tried to develop a new experimental design for individualized intervention by conducting n-of-1 trials using elderly subjects in a health care center but without detecting a clear effect. In conclusion, the safety of Japanese acupuncture or moxibustion was sufficiently demonstrated; however, a series of clinical trials could not offer convincing evidence to recommend the use of Japanese style acupuncture or moxibustion for preventing the common cold. Further studies are required as the present trials had several limitations.

- Abstract
The effects of repetitive electrical stimulation of a lumbar sympathetic trunk (LST) for 30 s at various frequencies and supramaximum intensity on the nerve blood flow in a sciatic nerve were studied by laser Doppler flowmetry in anesthetized Fischer-344 male rats. The response was biphasic; i.e. an initial increase and then a decrease. The maximum mean increase after 2 Hz stimulation was 22 +/- 8%, while the maximum mean decrease after 20-50 Hz stimulation was 79 +/- 3%, of the prestimulus control level. The initial increase, which was greater at lower frequencies and existed even after local sympathetic denervation, was passive, and was caused by the systemic pressor response to LST stimulation. The decrease, which was nearly abolished by an i.v. alpha-adrenergic blocker, phentolamine (10 mg/kg), resulted from vasoconstriction in the vasa nervorum, mainly via activation of alpha-adrenergic receptors.
