RESUMO
PURPOSE: To retrospectively investigate the safety and efficacy of percutaneous radiofrequency ablation (RFA) by analyzing results in patients with lung neoplasm accompanied by interstitial lung disease (ILD) on computed tomography (CT) in a multicenter study. MATERIALS & METHODS: Patients with lung neoplasm accompanied by ILD who underwent RFA between April 2002 and October 2017 at seven institutions were investigated. Technical success rate, and local tumor progression (LTP) of ablated tumors were evaluated. Adverse events including acute exacerbation of ILD were also evaluated. Univariate analyses were performed to identify factors associated with acute exacerbation. RESULTS: Forty-nine patients with 64 lung neoplasm (mean diameter, 22.6 mm; range, 4-58 mm) treated in 66 sessions were included. Usual interstitial pneumonia (UIP) pattern on CT was identified in 23 patients (47%). All patients underwent successful RFA. Acute exacerbations were seen in 5 sessions (8%: 7% with UIP pattern, 8% without) in 5 patients, all occurring on or after 8 days (median, 12 days; range, 8-30 days). Three of those 5 patients died of acute exacerbation. Treatment resulted in mortality after 5% of sessions, representing 6% of patients. Pleural effusion and fever ≥38°C after RFA were identified by univariate analysis (p = 0.0012, p = 0.02, respectively) as significant risk factors for acute exacerbation. The cumulative LTP rate was 43% at 1 year. CONCLUSIONS: RFA appears feasible for patients with lung neoplasm complicated by ILD. Acute exacerbation occurred in 8% of patients with symptoms occurring more than 8 days post-ablation and was associated with a 45% mortality rate.

Herein, we report the successful treatment using atezolizumab plus bevacizumab of a patient with hepatocellular carcinoma (HCC) with a portal vein tumor thrombus and multiple pulmonary metastases from rectal cancer with microsatellite stability. This patient developed rectal cancer with synchronous pulmonary metastases and HCC. After resecting the primary lesion of the rectal cancer, transcatheter arterial chemoembolization was performed for the HCC. Drug therapy was planned for multiple pulmonary metastases of rectal cancer; however, the early development of recurrent HCC with portal vein tumor thrombus had to be highly prioritized, and atezolizumab plus bevacizumab was introduced. Following the disappearance of the recurrent HCC lesion, the metastatic pulmonary nodules shrunk into scar-like spots. The treatment for both HCC and pulmonary metastases of rectal cancer were considered to result in clinical complete response.

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
BACKGROUND: Based on the JCOG1109 trial, it is suggested that the combination of docetaxel, cisplatin, and 5-fluorouracil (DCF) could potentially become a standard neoadjuvant chemotherapy regimen, alongside the conventional 5-fluorouracil and cisplatin (CF) therapy, for esophageal cancer. However, there are few reports on the impact of body composition changes associated with neoadjuvant chemotherapy on prognosis. AIM: Our study aimed to explore the effect of different neoadjuvant chemotherapy regimens on body composition during treatment and the impacts of body composition changes on their prognosis. METHODS AND RESULTS: This is a retrospective study of 215 patients with advanced thoracic esophageal cancer who had surgery after neoadjuvant chemotherapy from 2013 to 2019. Computed tomography scans were performed before and after neoadjuvant chemotherapy to assess body composition. Skeletal muscle mass index (SMI) was calculated by dividing total skeletal muscle mass at the 3rd lumbar level by the square of height, while visceral and subcutaneous fat masses were measured at the level of umbilicus. Patients in the lowest 25% of both sexes were classified into the low visceral fat and low subcutaneous fat groups, respectively. Of the patients enrolled, 178 were male and 37 were female. Among them, 91 had clinical Stage II disease, and 124 had clinical Stage III disease. Additionally, 146 patients received neoadjuvant chemotherapy CF, and 69 received neoadjuvant chemotherapy DCF. Comparing the DCF and CF groups, the DCF group consisted of significantly younger patients (p < .01), a higher proportion of males (p = .03), and a greater number of clinical Stage III cases (p < .01). However, although percent change in SMI and visceral fat mass was not significantly different between two regimens, percent change in subcutaneous fat mass was significant in the DCF group. The major prognostic factors for patients undergoing surgery after neoadjuvant chemotherapy for thoracic esophageal cancer were clinical Stage III, transition to low visceral fat, and response rating (SD/PD), while the specific neoadjuvant chemotherapy regimen did not significantly influence the outcomes. CONCLUSION: This study suggests that prevention of the shift to low visceral fat throughout the neoadjuvant chemotherapy process should improve patient outcomes.

Introduction: Hepatic arterial infusion chemotherapy (HAIC) with cisplatin and lenvatinib exhibits strong antitumor effects against advanced hepatocellular carcinoma (HCC). Higher antitumor activity is expected for the combination treatment. The aim of this trial was to evaluate the efficacy and safety of lenvatinib in combination with HAIC using cisplatin in patients with advanced HCC. Methods: In this multicenter, open-labeled, single-arm, phase II trial, patients with advanced HCC categorized as Child-Pugh class A with no prior history of systemic therapy were enrolled. Patients received lenvatinib plus HAIC with cisplatin (lenvatinib: 12 mg once daily for patients ≥60 kg, 8 mg once daily for patients <60 kg; HAIC with cisplatin: 65 mg/m2, day 1, every 4-6 weeks, maximum of six cycles). The primary endpoint was the objective response rate (ORR) assessed using modified RECIST by the Independent Review Committee. The secondary endpoints were the ORR assessed using RECIST v1.1, progression-free survival, overall survival, and frequency of adverse events associated with the treatment. Results: A total of 36 patients were enrolled between September 2018 and March 2020. In the 34 evaluable patients, the ORR assessed by the Independent Review Committee using modified RECIST and RECIST v1.1 were 64.7% (95% confidence interval [CI]: 46.5-80.3%) and 45.7% (95% CI: 28.8-63.4%), respectively. The median progression-free survival and overall survival were 6.3 months (95% CI: 5.1-7.9 months) and 17.2 months (95% CI: 10.9 - not available, months), respectively. The main grade 3-4 adverse events were increased aspartate aminotransferase (34%), leukopenia (22%), increased alanine aminotransferase (19%), and hypertension (11%). Conclusion: Lenvatinib plus HAIC with cisplatin yielded a favorable ORR and overall survival and was well tolerated in patients with advanced HCC. Further evaluation of this regimen in a phase III trial is warranted.
RESUMO
Introduction: Transarterial chemoembolization (TACE) is the standard treatment for unresectable intermediate-stage hepatocellular carcinoma (HCC), but recurrence after TACE is common. The present phase 2, prospective, multicenter, single-arm trial, the TACTICS-L trial, investigated the efficacy and safety of TACE plus lenvatinib (LEN), a drug that more strongly promotes vascular normalization and has a better objective response rate (ORR) than sorafenib (jRCTs031180074). Methods: Participants were patients with HCC who had not previously received systemic therapy, hepatic arterial infusion chemotherapy, or immunotherapy and who were ineligible for resection or percutaneous ablation therapy. LEN was to be administered 14-21 days before the first TACE, stopped 2 days before TACE, and resumed 3 days after TACE. Key inclusion criteria were unresectable HCC, Child-Pugh A liver function, 0-2 prior TACE sessions, tumor size ≤10 cm, number of tumors ≤10, and ECOG performance status 0-1. Key exclusion criteria were vascular invasion and extrahepatic spread. The primary endpoint was progression-free survival (PFS) by RECICL, and secondary endpoints were time to untreatable progression, ORR, overall survival (OS), and safety. Results: A total of 62 HCC patients were enrolled in this trial. The median age was 72 years, 77.4% of patients were men, and 95.2% had PS 0. The primary endpoint of median PFS was 28.0 months (90% confidence interval [CI] 25.1-31.0) after a minimum 24 months of follow-up. The secondary endpoint of median OS was not reached (90% CI 35.5 months-NR). LEN-TACE achieved a high response rate and high complete response (CR) rate (4 weeks after the first TACE: ORR 79.0%, CR rate 53.2%; best response: ORR 88.7%, CR rate 67.7%) by RECICL. Exploratory subgroup analyses showed that the characteristics of responders/nonresponders (ORR and CR rate) were similar and that LEN-TACE would be effective in all subgroups, including the population in whom TACE alone would be less likely to be curative (e.g., patients with the non-simple nodular type or a high tumor burden). The relative dose intensity of LEN before the first TACE was important for achieving higher CR rate/ORR by LEN-TACE. No new safety concerns were observed. Conclusion: The results of this trial provide encouraging evidence, supporting the efficacy and favorable safety profile of LEN-TACE in patients who are ineligible for locoregional therapy.
