ABSTRACT
BACKGROUND: The semiquantitative Clinical Frailty Scale (CFS) is reportedly a useful marker for predicting short- and mid-term mortality after transcatheter aortic valve implantation (TAVI). We assessed the long-term prognostic impact of CFS in patients with severe aortic stenosis undergoing TAVI. METHODS: We prospectively assessed patients undergoing TAVI in Kokura Memorial Hospital using a 9-level CFS and enrolled 1594 patients after excluding patients with CFS 8-9. The patients were divided into the low (CFS level, 1-3; N = 842), intermediate (4; N = 469), and high (5-7; N = 283) groups according to their CFS levels. RESULTS: In the low, intermediate, and high groups, 3-year all-cause mortality rates were 17.4%, 29.4%, and 41.7% (P < .001) and composite rates of cardiovascular mortality and heart failure hospitalization were 12.1%, 19.1%, and 23.9% (P < .001), respectively. Multivariable analysis showed that higher frailty was independently associated with all-cause mortality (intermediate group: adjusted hazard ratio [HR], 1.63, 95% confidence interval [CI], 1.24-2.15, P < .001; high group: adjusted HR, 2.18, 95% CI, 1.59-2.99, P < .001) and composite of cardiovascular mortality and heart failure hospitalization (intermediate group: adjusted HR, 1.47, 95% CI, 1.04-2.08, P = .030; high group: adjusted HR, 1.66, 95% CI, 1.09-2.51, P = .018) and this result was consistent, irrespective of stratification based on age, sex, body mass index, left ventricular ejection fraction, Society of Thoracic Surgeons score, and New York Heart Association functional class without significant interaction. CONCLUSIONS: The simple CFS tool predicts the long-term adverse outcomes post-TAVI.

Proteinuria has been described as a major on-target adverse event of lenvatinib, although its long-term impact on renal function and clinical outcomes remains unclear. We conducted a retrospective observational study to assess renal function and prognosis in patients with radioiodine-refractory differentiated thyroid cancer (RR-DTC) receiving lenvatinib. Overall, 70 patients with RR-DTC treated with lenvatinib were enrolled. When proteinuria was observed, the dose and schedule of lenvatinib were adjusted to achieve a urine protein-to-creatinine ratio (UPCR) of less than 3.5 g/gCre according to the study protocols of recent pivotal trials. In total, 50 (71%) and 25 (36%) patients presented with any-grade and grade 3 proteinuria, respectively. Multivariate analysis revealed that age [>65; odds ratio (OR) 8.24, 95% confidence interval (CI) 1.74-39.00, p < 0.01], history of diabetes mellitus (OR 7.79, 95% CI 1.31-46.20, p = 0.02), and hypertension (OR 4.07, 95% CI 1.22-13.60, p = 0.02) were significantly associated with the development of grade 3 proteinuria. Overall, the median estimating glomerular filtration rate (eGFR) gradually decreased every 3 months during treatment. However, no significant deterioration in eGFR was observed in patients with grade 3 proteinuria compared with patients with grades 0-2 proteinuria until 48 months. Patients who developed proteinuria had better survival outcomes than those without proteinuria. In conclusion, the proteinuria grade was not significantly associated with decreased eGFR under UPCR monitoring in our study. Therefore, lenvatinib can carefully be continued targeting UPCR of less than 3.5 g/gCre.

INTRODUCTION: Although systemic therapy, including multi-kinase inhibitors and cytotoxic chemotherapy, is an option for recurrent or metastatic adenoid cystic carcinoma of the head and neck (HNACC), it is not proven whether these therapies can prolong overall survival (OS). The present study investigated the impact of cytotoxic chemotherapy on survival outcomes compared with observation without chemotherapy. METHODS: We retrospectively reviewed the medical records of the patients diagnosed with recurrent or metastatic HNACC. We compared the survival outcomes, including survival time from recurrence/metastasis (OS) patients who received systemic chemotherapy with paclitaxel (200 mg/m2) and carboplatin (area under the curve 6) (TC) on day 1 of a 3-week cycle and observation alone. Subgroup analysis was conducted to identify patients who can get benefit from TC. RESULTS: Seventy-five patients (32 in TC and 43 in observation) were analyzed. There was no difference in median OS between TC and observation (52.2 months vs. 44.0 months, hazard ratio 0.76, 95% confidence interval 0.32-1.30, p = 0.21). Landmark analysis to reduce immortal bias also showed no difference between TC and observation in terms of OS. Subgroup analysis showed nonsignificant trends toward longer OS in asymptomatic patients with pulmonary metastasis and without bone metastasis. CONCLUSIONS: In our non-randomized comparison, patients who underwent TC did not show prolonged survival time from recurrence and/or metastasis diagnosis compared with observation alone in patients with recurrent or metastatic HNACC. Although systemic chemotherapy is a possible option for metastatic/recurrent HNACC, initial observation might be a valid strategy for asymptomatic patients without extrapulmonary diseases. Further research is warranted to identify the optimal patients and therapeutic regimens to prolong OS in HNACC.

BACKGROUND: Soft tissue sarcomas (STS) are a rare type of malignancy comprising a variety of histological diagnoses. Chemotherapy constitutes the standard treatment for advanced STS. Doxorubicin-based regimens, which include the administration of doxorubicin alone or in combination with ifosfamide or dacarbazine, are widely accepted as first-line chemotherapy for advanced STS. Trabectedin, eribulin, pazopanib, and gemcitabine plus docetaxel (GD), which is the empirical standard therapy in Japan, are major candidates for second-line chemotherapy for advanced STS, although clear evidence of the superiority of any one regimen is lacking. The Bone and Soft Tissue Tumor Study Group of the Japan Clinical Oncology Group (JCOG) conducts this trial to select the most promising regimen among trabectedin, eribulin, and pazopanib for comparison with GD as the test arm regimen in a future phase III trial of second-line treatment for patients with advanced STS. METHODS: The JCOG1802 study is a multicenter, selection design, randomized phase II trial comparing trabectedin (1.2 mg/m2 intravenously, every 3 weeks), eribulin (1.4 mg/m2 intravenously, days 1 and 8, every 3 weeks), and pazopanib (800 mg orally, every day) in patients with unresectable or metastatic STS refractory to doxorubicin-based first-line chemotherapy. The principal eligibility criteria are patients aged 16 years or above; unresectable and/or metastatic STS; exacerbation within 6 months prior to registration; histopathological diagnosis of STS other than Ewing sarcoma, embryonal/alveolar rhabdomyosarcoma, well-differentiated liposarcoma and myxoid liposarcoma; prior doxorubicin-based chemotherapy for STS, and Eastern Cooperative Oncology Group performance status 0 to 2. The primary endpoint is progression-free survival, and the secondary endpoints include overall survival, disease-control rate, response rate, and adverse events. The total planned sample size to correctly select the most promising regimen with a probability of > 80% is 120. Thirty-seven institutions in Japan will participate at the start of this trial. DISCUSSION: This is the first randomized trial to evaluate trabectedin, eribulin, and pazopanib as second-line therapies for advanced STS. We endeavor to perform a subsequent phase III trial comparing the best regimen selected by this study (JCOG1802) with GD. TRIAL REGISTRATION: This study was registered with the Japan Registry of Clinical Trials ( jRCTs031190152 ) on December 5, 2019.

An inflammatory myofibroblastic tumor is a rare component of bone and soft-tissue sarcomas that has distinct pathological features as a lymphoplasmacytic inflammatory infiltrate. As is the case for other non-small round cell sarcomas, surgical resection remains the standard treatment strategy for inflammatory myofibroblastic tumors, but recurrence is possible. Concerning systemic therapy, the available data for conventional chemotherapy (such as those of doxorubicin-based regimens) are limited, and case reports of anti-inflammatory inflammatory myofibroblastic tumor treatments describe some degree of symptom relief and efficacy against tumor progression. However, as more information about cancer genomics accumulates, the potential for molecularly targeted therapies for inflammatory myofibroblastic tumors has become more promising. Approximately half of inflammatory myofibroblastic tumors harbor anaplastic lymphoma kinase (ALK) fusion genes, and the other half could have potentially targetable fusion genes or mutations such as ROS1, NTRK and RET; case reports demonstrating the clinical efficacy of treatments targeted to inflammatory myofibroblastic tumor have been published, as have several prospective clinical trials. Few drugs are approved for the treatment of inflammatory myofibroblastic tumor, and most of them were approved for tumor-agnostic indications. Drugs that could be used for pediatric indications and dosing in inflammatory myofibroblastic tumor have also not been established. To provide effective targeted therapy for rare diseases such as inflammatory myofibroblastic tumor, it is necessary to obtain clinical evidence by designing and performing clinical trials and to find a path toward regulatory approval.

Human epidermal growth factor receptor 2 (HER2), coded by the proto-oncogene ERBB, is known to be mutated or amplified in various malignant diseases, and many HER2-targeted therapies (including monoclonal antibodies and low-molecular-weight tyrosine kinase inhibitors) have been investigated. HER2 overexpression is observed in ~30% of patients with osteosarcoma, and HER2-targeted therapy for osteosarcoma has also been investigated, along with the prognostic and/or predictive value of HER2. An effective HER2-targeted therapy for osteosarcoma has not been established, however. An antibody-drug conjugate (ADC), i.e., trastuzumab deruxtecan (T-DXd), has been approved for the treatment of HER2-positive malignant diseases such as breast cancer and gastric cancer. T-DXd showed promising efficacy in a tumor-agnostic clinical trial, but even T-DXd did not demonstrate sufficient efficacy against HER2-positive osteosarcoma. In this review, the underlying reasons/mechanisms for the failure of HER2-targeted treatments for osteosarcoma (including T-DXd) are discussed, and the potential and future direction of HER2-targeted therapy is described.

BACKGROUND: The clinical benefit of systemic chemotherapy for recurrent/metastatic retroperitoneal/intra-abdominal soft tissue sarcoma (STS) compared to its benefits for other primary lesions has not been known or sufficiently evaluated. METHODS AND PATIENTS: We retrospectively reviewed the cases of the STS patients who consulted a department of medical oncology in Tokyo between June 2011 and March 2018, and we extracted the cases of patients with primary sites at the retroperitoneum/intra-abdomen (cohort R) or extremities/trunk (cohort E) who received systemic chemotherapy in a recurrent/metastatic setting, comparing the cohorts' characteristics, chemotherapy details, and prognoses. RESULTS: Of all 337 STS patients, we enrolled 49 patients in cohort R and 75 patients in cohort E. Liposarcoma was more frequently observed in cohort R (51.0%) than cohort E (22.7%). The median chemotherapy treatment line was two lines (range: 1-6) in cohort R and three lines (range: 1-9) in cohort E. The doxorubicin usage rates differed in recurrent/metastatic settings (90.0% in cohort R and 55.0% in cohort E), due mainly to the higher rate of a perioperative chemotherapy treatment history in cohort E (52.0% vs. 6.1% in cohort R). The median overall survival from the start of salvage chemotherapy was 31.9 months (cohort R; 95% CI: 20.9-42.8) and 27.1 months (cohort E; 95% CI: 21.6-32.5) (p = 0.549). CONCLUSION: There were differences in the distributions of pathology and antitumor drugs used in a salvage setting between retroperitoneal/intra-abdominal and extremities/trunk STS patients in recurrent/metastatic settings, but the prognoses with salvage chemotherapy were similar in the two cohorts.

BACKGROUND: Heart failure (HF) is one of the potential adverse events of pazopanib treatment for soft tissue sarcoma (STS), but detailed reports of such HF cases are scarce. This study determined the incidence and risk factors of HF following pazopanib treatment for STS at our Institute and the clinical outcomes.MethodsâandâResults:This study retrospectively analyzed the cases of STS patients treated with pazopanib (n=151) between 2012 and 2020. HF occurred in 6 patients (3.9%) at the median onset of 137 (range 14-468) days after the treatment initiation. When their HF was diagnosed, pazopanib was interrupted in all 6 patients. No patients experienced HF-related death, and HF development was not a significant factor for poor overall survival. The cumulative doses of anthracyclines (>225 mg/m2) before pazopanib initiation (83% vs. 37%, P=0.031), pazopanib initiation at age ≥60 years (83% vs. 35%, P=0.026), and the baseline B-type natriuretic peptide (BNP) concentration (≥50 pg/mL) before pazopanib (67% vs. 11%, P=0.002) initiation were predictive factors for post-pazopanib treatment HF. CONCLUSIONS: The study findings highlight the effect of past anthracycline exposure and baseline BNP for pazopanib-associated HF. Although the study patients' clinical outcomes were generally favorable, periodic monitoring of cardiac function using ultrasonic echocardiography or serum markers is essential to detect events early and begin therapeutic intervention appropriately under a cardiologist's instructions.
ABSTRACT
Bone sarcoma is a rare component of malignant solid tumors that accounts for only ~0.2% of malignancies. Bone sarcomas present various histological types, and genomic mutations differ markedly by the histological types. Although there are vast mutations in various bone sarcomas, most of them are non-actionable, and even potential targetable mutations that are actionable targets in other malignancies have not shown the appropriate responses in clinical trials for bone sarcomas. Investigations of new systemic therapy, including molecular targeted therapies for bone sarcomas, have thus not progressed like those for other solid tumors. Another problem is that high rates of pediatric/adolescent and young adult patients have bone sarcomas such as osteosarcoma, and patient recruitment for clinical trials (especially randomized trials) is challenging. For pediatric patients, evaluations of tolerability and appropriate dose modifications of new drugs are needed, as their findings could provide the threshold for investigating new drugs for bone sarcomas. To solve these problems, improvements in registry systems, real world data, and pediatric extrapolation have been attempted. We review the issues regarding targeted drug investigations for bone sarcomas, focusing on the current clinical evidence and efforts to resolve these issues.

Several autoantigens related to inflammatory myopathy have been identified. Antimitochondrial antibody M2 (AMA-M2) is known as one of the serologic hallmarks of primary biliary cholangitis (PBC). There have been several reports on the association between AMA-M2 and various types of inflammatory myopathy, including cardiomyopathy. We report a case of a 58-year-old man with decompensated heart failure who also had PBC and skeletal inflammatory myopathy. Endomyocardial biopsy revealed severe fibrotic replacement of the myocardium without massive inflammatory infiltration, which was pathologically similar to what happens in dilated cardiomyopathy (DCM). Although the potential relationship between chronic autoimmune inflammation and DCM has been discussed, the concept of the inflammatory DCM has not yet been established. When we see elevated liver enzymes, and which is not simply due to congestive hepatopathy, we should consider the coexisting disease such as PBC.

Milademetan (DS-3032, RAIN-32) is an orally available mouse double minute 2 (MDM2) antagonist with potential antineoplastic activity owing to increase in p53 activity through interruption of the MDM2-p53 interaction. This phase I, dose-escalating study assessed the safety, tolerability, efficacy, and pharmacokinetics of milademetan in 18 Japanese patients with solid tumors who relapsed after or were refractory to standard therapy. Patients aged ≥ 20 years received oral milademetan once daily (60 mg, n = 3; 90 mg, n = 11; or 120 mg, n = 4) on days 1 to 21 in a 28-day cycle. Dose-limiting toxicities, safety, tolerability, maximum tolerated dose, pharmacokinetics, and recommended dose for phase II were determined. The most frequent treatment-emergent adverse events included nausea (72.2%), decreased appetite (61.1%), platelet count decreased (61.1%), white blood cell count decreased (50.0%), fatigue (50.0%), and anemia (50.0%). Dose-limiting toxicities (three events of platelet count decreased and one nausea) were observed in the 120-mg cohort. The plasma concentrations of milademetan increased in a dose-dependent manner. Stable disease was observed in seven out of 16 patients (43.8%). Milademetan was well tolerated and showed modest antitumor activity in Japanese patients with solid tumors. The recommended dose for phase II was considered to be 90 mg in the once-daily 21/28-day schedule. Future studies would be needed to further evaluate the potential safety, tolerability, and clinical activity of milademetan in patients with solid tumors and lymphomas. The trial was registered with Clinicaltrials.jp: JapicCTI-142693.

Neuroendocrine carcinoma (NEC) of the head and neck is a rare type of malignancy, accounting for only 0.3% of all head and neck cancers, and its clinicopathological and genomic features have not been fully characterized. We conducted a retrospective analysis of 27 patients with poorly differentiated NEC of the head and neck seen at our institution over a period of 15 years. Patient characteristics, adopted therapies, and clinical outcomes were reviewed based on the medical records. Pathological analysis and targeted sequencing of 523 cancer-related genes were performed using evaluable biopsied/resected specimens based on the clinical data. The most common tumor locations were the paranasal sinus (33%) and the oropharynx (19%). Eighty-one percent of the patients had locally advanced disease. The 3-year overall survival rates in all patients and in the 17 patients with locally advanced disease who received multimodal curative treatments were 39% and 53%, respectively. Histologically, large cell neuroendocrine carcinoma was the predominant subtype (58% of evaluable cases), and the Ki-67 labeling index ranged from 59 to 99% (median: 85%). Next-generation sequencing in 14 patients identified pathogenic/likely pathogenic variants in TP53, RB1, PIK3CA-related genes (PREX2, PIK3CA, and PTEN), NOTCH1, and SMARCA4 in six (43%), three (21%), two (14%), two (14%), and one (7%) patients, respectively. Sequencing also detected the FGFR3-TACC3 fusion gene in one patient. The median value of the total mutational burden (TMB) was 7.1/Mb, and three patients had TMB ≥ 10. Regardless of the aggressive pathological features, our data revealed favorable clinical characteristics in the patients with locally advanced disease who received curative treatment. The lower TP53 and RB1 mutation prevalence rates compared to those described for small cell lung cancer suggests the biological heterogeneity of NEC in different parts of the body. Furthermore, the FGFR3-TACC3 fusion gene and mutations in genes encoding the components of the NOTCH and PI3K/AKT/mTOR pathways found in our study may be promising targets for NEC of the head and neck.

BACKGROUND: Pneumocystis jirovecii pneumonia (PCP)-related risk factors among patients with solid tumors are not completely defined. Thus, we aimed to characterize PCP cases with underlying solid tumors, to highlight the factors contributing to its development besides the prolonged use of moderate-to-high dose corticosteroids. METHODS: We retrospectively reviewed the medical records of patients with solid tumors diagnosed with PCP between 2006 and 2018 at a cancer center in Tokyo, Japan. Demographic and clinical data were collected, which included malignancy types, total lymphocyte count, coexisting pulmonary disease, chemotherapy, radiation therapy, corticosteroid use, and PCP-attributable mortality. RESULTS: Twenty cases of PCP with solid tumors were documented in 151,718 patients and 788,914 patient-years. Lung cancer (n = 6, 30%) was the most common underlying tumor, followed by breast cancer (n = 3, 15%). Only six (30%) patients were taking a dosage of ≥20 mg prednisone equivalents daily for ≥4 weeks from the onset of PCP. Among the remaining 14 patients, seven (50%) had coexisting pulmonary diseases, 10 (71%) had received chemotherapy within 90 days prior to PCP diagnosis, seven (50%) had undergone chest radiation therapy before PCP diagnosis, seven (50%) had received only intermittent corticosteroids, and one (7%) received no corticosteroids. Mortality attributable to PCP was 40%. CONCLUSIONS: More than half of the patients were not taking a dosage of ≥20 mg prednisone equivalents daily for ≥4 weeks. Multiple other factors (e.g., lymphocytopenia, radiation to chest) may have potentially contributed to PCP in patients with solid tumors in a composite manner. We need to establish a method for estimating the likelihood of PCP taking multiple factors into account in this patient population.

Lenvatinib is a standard therapy for radioiodine-refractory differentiated thyroid cancer (RR-DTC). However, because of the high incidence of adverse events resulting from this treatment, it is not easy to maintain the dose intensity of lenvatinib, especially in Japanese patients. Although the prognostic impact of lenvatinib dose interruption has been reported, the target dose intensity of lenvatinib to optimize survival benefits remains unknown. We therefore propose a target dose intensity of lenvatinib during the first 8 weeks of treatment. We retrospectively analyzed 42 RR-DTC patients who were treated with lenvatinib for more than 8 weeks. We performed receiver operating characteristic curve analysis to determine the cut-off value of 8 weeks' relative dose intensity (8w-RDI) to predict treatment response, and identified that the optimal cut-off value of 8w-RDI was 60% (sensitivity: 81.8%; specificity: 80.6%). Median progression-free survival (PFS) (not reached [NR] vs. 11.0 months; hazard ratio [HR] 0.29; 95% confidence interval [CI] 0.11-0.72; p < 0.01) and overall survival (NR vs. 27.6 months; HR 0.44; 95% CI 0.11-0.91; p = 0.03) were longer in the higher 8w-RDI (≥60%) patients than in the lower 8w-RDI (<60%) patients. Multivariate analysis revealed that 8w-RDI at ≥60% was an independent prognostic factor for PFS (HR 0.29; 95% CI 0.09-0.96; p = 0.04). Targeting for ≥60% of the relative dose intensity during the first 8 weeks of lenvatinib treatment can be sufficient to achieve significant tumor shrinkage and prolong PFS in RR-DTC patients.

Cytotoxic chemotherapy, including cyclophosphamide, vincristine, and dacarbazine (CVD) therapy, is widely used to treat metastatic pheochromocytoma and paraganglioma. Because these diseases are rare, studies are needed to establish treatment strategies. This was a single-center and retrospective study to analyze the efficacy of chemotherapy for patients with metastatic pheochromocytoma and paraganglioma diagnosed in 1983-2020. Clinical characteristics, tumor volume response, biochemical response based on catecholamine level, overall survival, and progression-free survival were evaluated. Patients with a complete response or partial response in tumor volume or catecholamine level were classified as responders. Sixteen patients were administered chemotherapy for a median of 16.5 cycles (interquartile range, 10-42). The tumor volume response was classified as follows: partial response (N = 4), stable disease (N = 9), and progressive disease (N = 3) (disease control rate = 81%). The biochemical responses were as follows: complete response (N = 2), partial response (N = 5), no change (N = 3), and progressive disease (N = 1) (disease control rate = 91%). The 5-year survival rate was 50% (95% confidence interval [CI], 21-74%) and median overall survival was 4.4 years (95% CI, 2.4 years-not reached). Overall survival and progression-free survival between responders and nonresponders were not statistically different. One patient developed myelodysplastic syndrome during CVD therapy. In conclusion, chemotherapy achieved disease control among more than half of patients, although survival did not differ between responders and nonresponders. Further fundamental research and prospective trials are needed to analyze the efficacy of CVD therapy.

Adrenocortical carcinoma (ACC) is a rare malignancy with a poor prognosis. While mitotane is the only agent approved for ACC, clinical data are scarce, especially in the Asian population. We reviewed 10 patients with ACC who received mitotane as a single agent or in combination with other agents in our institution. Patient characteristics, clinical outcomes, and toxicities were analyzed. Mitotane was administered to 2 patients as an adjuvant therapy and to 8 patients for systemic control. In the latter 8 patients, 1 patient had locally advanced disease and 1 had metastatic disease at the time of initial diagnosis, whereas the other 6 patients experienced metastatic relapse at mitotane initiation. The administered regimen was mitotane alone in 7 patients, and mitotane plus cytotoxic chemotherapy in 3 patients. The initial daily mitotane dose was 3.0 g in 2 patients, 1.5 g in 7 patients, and 1.0 g in 1 patient. The median duration of treatment was 3.7 (range, 0.7-22.1) months. In 8 systemic cases, the median overall survival from chemotherapy initiation was 7.2 months, and only 1 patient survived over 1 year. The median interval from mitotane termination to death in systemic cases was 2.8 months, and the cause was progressive disease in 4 patients and toxicity (hallucination, mycobacteriosis, or liver injury) in 3 patients. As a second-line regimen, 2 systemic cases and 1 adjuvant case were enrolled in clinical trials. Our analysis exhibited extremely poor prognosis under mitotane-based regimens, and further treatment strategies are warranted to improve outcomes.

OBJECTIVE: To report our institutional experience with treatment of primary genitourinary soft tissue sarcoma. METHODS: We retrospectively reviewed the medical records of adult soft tissue sarcoma patients treated between March 2005 and May 2019. The primary tumor sites included the prostate, kidney, urinary bladder and the paratesticular structures. RESULTS: A total of 19 patients - 16 men (84%) and three women (16%) - were enrolled in the study. The median age was 41 years (range 20-79 years). The most common primary site was the prostate (in eight patients; 42%), and prostatic sarcoma patients were younger than patients with sarcomas of other origins. The most common histological subtype was leiomyosarcoma (in five patients; 26%). The overall survival rates after 1, 3 and 5 years were 61.5%, 34.4% and 25.8%, respectively. The median survival time was 20.7 months (95% confidence interval 5.9-35.5 months). Univariate analysis showed that an absence of metastasis at diagnosis and complete surgical resection were predictive of favorable survival. In the chemotherapy group, the objective response rate was 20.5%. Pazopanib was administered to nine patients in the late-line setting, and the objective response rate was 11.1%; six grade ≥3 adverse events were observed in three patients. CONCLUSIONS: Inoperable metastatic genitourinary soft tissue sarcoma remains difficult to treat, as previously reported. Further investigation on this malignancy, including optimization of currently available antitumor drugs and the development of novel therapeutic agents, is required.

PURPOSE: Large prospective studies of chemotherapy for metastatic or recurrent adenoid cystic carcinoma (ACC) of the head and neck are lacking due to the rarity of ACC. The aim of this study is to evaluate the efficacy of carboplatin plus paclitaxel toward ACC and perform an exploratory investigation of the prognostic factors to investigate the optimal strategy for metastatic or recurrent ACC. METHODS: We retrospectively analyzed recurrent or metastatic ACC patients treated with carboplatin plus paclitaxel between April 2007 and September 2019 in our hospital. Objective response rate (ORR), disease control rate (DCR), progression-free survival (PFS), and overall survival (OS) were evaluated, and an exploratory analysis of the prognostic factors was conducted. RESULTS: A total of 26 ACC patients were enrolled. ORR and DCR were 11.5 and 76.9%; the median PFS and OS were 8.1 and 22.3 months, respectively. From the results of the multivariate analysis, higher (≥ 6%/month) tumor growth rate (TGR) was associated with worse PFS (hazard ratio [HR] 7.00, 95% CI 1.34-36.53, p = 0.02) and OS (HR 29.33, 95% CI 3.38-254.80, p < 0.01). The median PFS (10.6 vs. 6.6 months, log-rank p < 0.05) and OS (48.5 vs. 16.9 months, log-rank p < 0.01) were significantly shorter in patients with higher TGR. CONCLUSIONS: Carboplatin plus paclitaxel showed modest efficacy for recurrent or metastatic ACC patients. Watchful waiting may be optimal for ACC patients with lower TGR. Systemic chemotherapy should be considered when TGR increases during active surveillance.

We report a fatal case of invasive pulmonary aspergillosis caused by voriconazole-resistant Aspergillus tubingensis in a patient with solid tumor but without severe immunosuppression. A high index of suspicion for invasive pulmonary aspergillosis, coupled with molecular identification of species and resistance genes, may facilitate early initiation of appropriate treatment.

AIM: To investigate the safety and efficacy of lenvatinib in advanced thyroid cancer. PATIENTS/METHODS: In this Phase II study, 51 Japanese patients with radioiodine-refractory differentiated thyroid cancer (RR-DTC), medullary thyroid cancer (MTC) or anaplastic thyroid cancer (ATC) received once-daily lenvatinib 24 mg. The primary end point was safety. RESULTS: All patients experienced ≥1 adverse event (AE); only one patient experienced an AE leading to discontinuation. The most common any-grade AEs were hypertension, decreased appetite, palmar-plantar erythrodysesthesia, fatigue and proteinuria. Response rates for RR-DTC: 68%; MTC: 22%; ATC: 24%. Median progression-free survival for RR-DTC: 25.8 months; MTC: 9.2 months; ATC: 7.4 months. CONCLUSION: Lenvatinib demonstrated a manageable safety profile, proven antitumor activity in RR-DTC and promising efficacy in MTC and ATC. CLINICAL TRIAL REGISTRATION: clinicaltrials.gov NCT01728623.
