RESUMO
INTRODUCTION: This study examines whether neoadjuvant docetaxel, cisplatin plus S-1 (DCS) therapy is superior to docetaxel, cisplatin plus 5-fluorouracil (DCF) therapy for resectable advanced esophageal squamous cell carcinoma (ESCC). METHODS: Patients diagnosed with resectable advanced ESCC at our hospital between January 2010 and December 2019 underwent either neoadjuvant DCF therapy or DCS therapy, followed by radical esophagectomy. Prior to August 2014, we usually used neoadjuvant DCF therapy; we then completely transitioned to using neoadjuvant DCS therapy. RESULTS: A total of 144 patients received one of these triplet regimens as neoadjuvant chemotherapy: DCF therapy to 67 patients and DCS therapy to 77 patients. After propensity score matching, 55 patients in each group were selected as matched cohorts. There was no significant difference between the groups in complete response (DCF = 7.3%, DCS = 9.1%) or in partial response (DCF = 45.4%, DCS = 52.7%). The pathological response rate was 23.8% for grade 2 and 18.2% for grade 3 in the DCF group, compared with 30.9% and 14.5% in the DCS group. Independent predictive factors for recurrence-free survival were poor clinical response and pathological response ≤1b. Independent prognostic factors for overall survival were poor clinical response, anastomotic leakage, and pathological response ≤1b. Duration of hospital stays in the DCS group was significantly shorter than those of the DCF group (6.0 vs. 15.0 days, p < 0.001). Expenses of drug and hospitalization for the neoadjuvant chemotherapy in the DCS group were also significantly lower than those of the DCF group (265.7 vs. 550.3 USD, p < 0.001). CONCLUSIONS: Neoadjuvant DCS therapy for resectable advanced ESCC did not result in significantly higher clinical and pathological response than neoadjuvant DCF therapy. However, neoadjuvant DCS therapy for resectable ESCC required comparatively shorter hospital stays and incurred lower costs, making it an attractive therapeutic option.

INTRODUCTION: We demonstrated that there was a significant relationship between the severity measured using the A-DROP scoring system and the mortality rate in patients with COVID-19 community-acquired pneumonia (CAP) in the ancestral strain, Alpha variant, and Delta variant. We investigated the usefulness of the A-DROP scoring system in SARS-CoV-2 Omicron variant CAP and compared it with severity scores, the Pneumonia Severity Index (PSI) and CURB-65 score. METHODS: We analyzed a total of 547 patients with COVID-19 CAP Omicron variant; 198 cases were the BA.1 subvariant, 127 cases were the BA.2 subvariant, and 222 cases were the BA.5 subvariant, respectively. RESULTS: The mortality rates in patients with COVID-19 CAP among the three Omicron subvariants were identical in each pneumonia severity group. The mortality rate in patients with the Omicron variant was 0 % in patients classified with mild disease, 0.6 % in those with moderate disease, 10.4 % in those with severe disease, and 34.8 % in those with extremely severe disease. The mortality rate in patients with COVID-19 CAP increased depending on the severity classified according to the A-DROP system in each of the Omicron subvariants (Cochran-Armitage trend test; p < 0.001). The values of the area under the curve in Receiver Operating Characteristic analysis for prediction of 30-day mortality was 0.881, 0.879, and 0.863 for A-DROP, PSI, and CURB-65, respectively. There were no significant differences in the predictive ability of each pneumonia severity score. CONCLUSIONS: Our results demonstrated that the A-DROP scoring system is useful for predicting mortality in patients with COVID-19 CAP.

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.

Aim: To provide a real-world snapshot of the clinical profile, management, and patient-reported outcomes (PRO) for advanced medullary and papillary thyroid cancer prior to the availability of rearranged during transfection (RET) inhibitors in Japan. Materials & methods: Physicians completed patient-record forms for eligible patients seen during routine clinical practice. Physicians were also surveyed about their routine practice and patients were asked to provide PRO data. Results: RET testing patterns varied by hospital type; no therapeutic relevance was a commonly cited reason to not carry out testing. Multikinase inhibitors were the main systemic therapies prescribed, although timing to start multikinase inhibitors varied; adverse events were reported as challenges. PROs revealed high disease/treatment burden. Conclusion: More effective and less toxic systemic treatment targeting genomic alterations is needed to improve long-term outcomes of thyroid cancer.
This survey, conducted in Japan in 2020, included doctors who treat thyroid cancer and their patients. It is called a real-world survey because it provides information such as the types of tests and treatments used for thyroid cancer management in everyday clinical practice. The survey focused on two types of thyroid cancer: papillary thyroid cancer (PTC), a common type, and medullary thyroid cancer (MTC), an uncommon type. About 1020% of people with PTC and most people with MTC have alterations in a gene called RET, which caused the cancer. Laboratory tests can identify these gene alterations, fusions (joining the parts of two different genes) or mutations (changes to a gene's DNA sequence) and results can help guide treatment decisions. The survey showed that testing for RET gene alterations was less than optimal and varied by the type of hospital/center. Common reasons provided by doctors for not testing for RET alterations were, "no therapeutic relevance for patient management" and "specific targeted therapies not available". However, the survey was conducted before the availability in Japan of the treatment selpercatinib, which selectively targets/inhibits tumors with RET alterations. Most patients in the survey, including those with RET alterations, received treatment with a type of inhibitor called multikinase inhibitors, as per available guidelines. Doctors considered side effects due to inhibition of multiple targets by multikinase inhibitors to be among areas for improvement needed. People with PTC and MTC also reported substantial burdens (i.e., negative impact on their lives) from the disease/treatment. The researchers concluded that barriers to RET testing need to be overcome, and more effective and less toxic treatments targeting gene alterations are needed to improve long-term outcomes.

INTRODUCTION: The Japanese Respiratory Society (JRS) pneumonia guidelines recommend simple predictive rules, the A-DROP scoring system, for assessment of the severity of community-acquired pneumonia (CAP) and nursing and healthcare-associated pneumonia (NHCAP). We evaluated whether the A-DROP system can be adapted for assessment of the severity of coronavirus disease 2019 (COVID-19) pneumonia. METHODS: Data from 1141 patients with COVID-19 pneumonia were analyzed, comprising 502 patients observed in the 1st to 3rd wave period, 338 patients in the 4th wave and 301 patients in the 5th wave in Japan. RESULTS: The mortality rate and mechanical ventilation rate were 0% and 1.4% in patients classified with mild disease (A-DROP score, 0 point), 3.2% and 46.7% in those with moderate disease (1 or 2 points), 20.8% and 78.3% with severe disease (3 points), and 55.0% and 100% with extremely severe disease (4 or 5 points), indicating an increase in the mortality and mechanical ventilation rates in accordance with severity (Cochran-Armitage trend test; p = <0.001). This significant relationship between the severity in the A-DROP scoring system and either the mortality rate or mechanical ventilation rate was observed in patients with COVID-19 CAP and NHCAP. In each of the five COVID-19 waves, the same significant relationship was observed. CONCLUSIONS: The mortality rate and mechanical ventilation rate in patients with COVID-19 pneumonia increased depending on severity classified according to the A-DROP scoring system. Our results suggest that the A-DROP scoring system can be adapted for the assessment of severity of COVID-19 CAP and NHCAP.

INTRODUCTION: The Japanese Respiratory Society (JRS) atypical pneumonia score is a useful tool for the rapid presumptive diagnosis of atypical pneumonia. We investigated the clinical features of community-acquired pneumonia (CAP) due to Chlamydia psittaci and validated the JRS atypical pneumonia score in patients with C. psittaci CAP. METHODS: This study was conducted at 30 institutions and assessed a total of 72 sporadic cases with C. psittaci CAP, 412 cases with Mycoplasma pneumoniae CAP, and 576 cases with Streptococcus pneumoniae CAP. RESULTS: Sixty-two of 72 patients with C. psittaci CAP had a history of avian exposure. Among the six parameters of the JRS score, matching rates of four parameters were significantly lower in the C. psittaci CAP than the M. pneumoniae CAP in the following parameters: age <60 years, no or minor comorbid illness, stubborn or paroxysmal cough, and absence of chest adventitious sounds. The sensitivity of the diagnosis of atypical pneumonia in patients with C. psittaci CAP was significantly lower than the M. pneumoniae CAP (65.3% and 87.4%, p < 0.0001). When the diagnostic sensitivity was analyzed for different ages, the diagnostic sensitivities for the C. psittaci CAP were 90.5% for non-elderly patients and 30.0% for elderly patients. CONCLUSIONS: The JRS atypical pneumonia score is a useful tool for distinguishing between C. psittaci CAP and bacterial CAP in patients aged <60 years, but not in patients aged ≥60 years. A history of avian exposure in middle-aged patients with normal white blood cell count may be suggestive of C. psittaci pneumonia.

PURPOSE: The stomach is the most common organ which is used for reconstruction after esophagectomy for esophageal cancer. It is controversial which is better narrow gastric tube reconstruction or whole stomach reconstruction to prevent anastomotic leakage. METHODS: From August 2022 to March 2023, we started a prospective cohort study of whole stomach reconstruction after esophagectomy. Until then (from January 2018 to July 2022), narrow gastric tube reconstruction was performed as a standard reconstruction. RESULTS: Narrow gastric tube reconstruction and whole stomach reconstruction were performed in 183 patients and 20 patients, respectively. The patient's characteristics were not significantly different between the narrow gastric tube group and the whole stomach group. In particular, for all patients in the whole stomach reconstruction group, retrosternal route and esophagogastrostomy by hand sewn were applied. There were no occurrences of AL through the continuous 20 cases in the whole stomach group, otherwise 42 (22.9%) patients in the narrow gastric group (P = 0.016). Postoperative hospital stays were significantly shorter in the whole stomach group than in the narrow gastric group (21 days vs. 28 days, P < .001). Blood perfusions were evaluated by indocyanine green for all cases, which had very good blood perfusion in all cases. Additionally, quantitative blood perfusion was examined by SPY-QP (Stryker, USA) for one case. Even the edge of the fornix showed more than 90% blood perfusion levels when the antrum was fixed as the reference point. CONCLUSION: Whole stomach reconstruction with excellent blood perfusion is considered to be safe and has the possibility to prevent from occurring AL after esophagectomy for esophageal cancer patients.

BACKGROUND: Alpha-Fetoprotein Producing Gastric Cancer (AFPGC) is an aggressive subgroup of gastric cancer. Recently ramucirumab has shown survival benefits in hepatocellular carcinoma, but only in those with higher Alpha-Fetoprotein (AFP) levels. However, the efficacy of ramucirumab-containing chemotherapy in AFPGC remains unclear. METHODS: We retrospectively assessed 352 patients who received ramucirumab-containing chemotherapy between June 2015 and December 2019. AFPGC was defined when serum AFP levels were elevated at diagnosis and correlated with the disease state during treatment. Non-AFPGC was defined when serum AFP levels were normal at diagnosis. RESULTS: Among the 352 patients, 28 patients were defined as AFPGC and 246 patients were defined as non-AFPGC. AFPGC was characterized by high frequency of liver metastasis and low frequency of peritoneal metastasis compared to non-AFPGC. Ramucirumab containing chemotherapy showed higher response rates in AFPGC (39.1% vs 24.8%, p = 0.198) and disease control rates (86.9% vs 61.5%, p = 0.028) than those of non-AFPGC, respectively. Median progression-free survival (PFS) was 5.5 months (95%CI 3.9-7.1) in AFPGC and 4.0 months (95%CI 3.6-4.6) in non-AFPGC (HR: 0.91, 95% CI 0.61-1.36, p = 0.66), and median overall survival (OS) was 10.7 months (95% CI 7.4-20.8) in AFPGC and 9.2 months (95% CI 8.1-10.4) in non-AFPGC (HR: 0.72, 95% CI 0.48-1.08, p = 0.11), respectively. In multivariate analysis, AFPGC was not a negative prognostic factor both for PFS and OS. CONCLUSION: Ramucirumab containing chemotherapy showed higher response and comparable survival in AFPGC compared to those of non-AFPGC. Considering the generally poor prognosis of AFPGC, ramucirumab-containing chemotherapy might be a promising treatment option in AFPGC.

Diaphragmatic hernia is a very rare but high-risk complication after esophagectomy. Although there are many studies on the Ivor Lewis esophagectomy procedure for diaphragmatic hernia, there are fewer studies on the McKeown procedure. The present study aimed to estimate the incidence of diaphragmatic hernia after esophagectomy, describing its presentation and management with the McKeown procedure. We retrospectively evaluated the 622 patients who underwent radical esophagectomy between January 2002 and December 2020 at the Wakayama Medical University Hospital. Statistical analyses were performed to evaluate risk factors for diaphragmatic hernia. Emergency surgery for postoperative diaphragmatic hernia was performed in nine of 622 patients (1.45%). Of these nine patients, one developed prolapse of the small intestine into the mediastinum (11.1%). The other eight patients underwent posterior mediastinal route reconstructions (88.9%), one of whom developed prolapse of the gastric conduit, and seven of whom developed transverse colon via the diaphragmatic hiatus. Laparoscopic surgery was identified in multivariate analysis as the only independent risk factor for diaphragmatic hernia (odd's ratio [OR] = 9.802, p = 0.034). In all seven cases of transverse colon prolapse into the thoracic cavity, the prolapsed organ had herniated from the left anterior part of gastric conduit. Laparoscopic surgery for esophageal cancer is a risk factor for diaphragmatic hernia. The left anterior surface of gastric conduit and diaphragmatic hiatus should be fixed firmly without compromising blood flow to the gastric conduit.

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.
RESUMO
BACKGROUND: Laparoscopic sleeve gastrectomy (LSG) for morbid obesity may improve gut microbiota balance and decrease chronic inflammation. This study examines the changes in gut microbiota and immune environment, including mucosal-associated invariant T cells (MAIT cells) and regulatory T cells (Treg cells) caused by LSG. METHODS: Ten morbidly obese patients underwent LSG at our institution between December 2018 and March 2020. Flow cytometry for Th1/Th2/Th17 cells, Treg cells and MAIT cells in peripheral blood and colonic mucosa and 16S rRNA analysis of gut microbiota were performed preoperatively and then 12 months postoperatively. RESULTS: Twelve months after LSG, the median percent total weight loss was 30.3% and the median percent excess weight loss was 66.9%. According to laboratory data, adiponectin increased, leptin decreased, and chronic inflammation improved after LSG. In the gut microbiota, Bacteroidetes and Fusobacteria increased after LSG, and indices of alpha diversity increased after LSG. In colonic mucosa, the frequency of MAIT cells increased after LSG. In peripheral blood, the frequency of Th1 cells and effector Treg cells decreased after LSG. CONCLUSIONS: After LSG for morbid obesity, improvement in chronic inflammation in obesity is suggested by change in the constituent bacterial species, increase in the diversity of gut microbiota, increase in MAIT cells in the colonic mucosa, and decrease in effector Treg cells in the peripheral blood.

INTRODUCTION: Casirivimab-imdevimab, an antibody cocktail containing two severe acute respiratory syndrome coronavirus 2 neutralizing antibodies, reduces the viral load and the risk of coronavirus disease 2019 (COVID-19)-related hospitalization or death. The objective of this study was to evaluate the clinical efficacy of casirivimab-imdevimab in patients with COVID-19 Delta variant in Japan. METHODS: This study was conducted at five institutions and assessed a total of 461 patients with COVID-19 who met the inclusion criteria. The treatment group received a dose of casirivimab-imdevimab consisting of a cocktail of two monoclonal antibodies, (casirivimab 600 mg and imdevimab 600 mg intravenously). The control consisted of age- and sex-matched COVID-19 patients (n = 461) who sufficed the inclusion criteria but did not receive casirivimab-imdevimab. The outcome was the requirement of oxygen therapy. RESULTS: In the treatment group, patients received oxygen therapy (n = 30), nasal canula (n = 23), high flow nasal cannula (n = 5), and mechanical ventilation (n = 2). In the control group, patients received oxygen therapy (n = 56), nasal canula (n = 45), high flow nasal cannula (n = 8), and mechanical ventilation (n = 3). The administration of oxygen therapy was significantly lower in the treatment group than the control group (6.5% vs. 12.1%, P = 0.0044). All these patients admitted to our hospitals and received additional therapy and recovered. CONCLUSIONS: Our results demonstrate that the casirivimab-imdevimab combination antibody treatment is associated with reduced rates of requiring oxygen therapy among high-risk patients with COVID-19 Delta variant.

INTRODUCTION: The Japanese Respiratory Society (JRS) scoring system is a useful tool for the rapid presumptive diagnosis of atypical pneumonia in non-elderly (aged <60 years) patients. As SARS-CoV-2 vaccination progresses, COVID-19 in elderly people has markedly reduced. We investigated changes in diagnostic usefulness of the JRS scoring system in COVID-19 pneumonia between the Delta variant group (vaccination period) and non-Delta variant group (before the vaccination period). METHODS: This study was conducted at five institutions and assessed a total of 1121 patients with COVID-19 pneumonia (298 had the Delta variant). During the vaccination period, the Delta variant has spread and replaced the Alfa variant. We evaluated the vaccination period as the Delta variant group. RESULTS: Among the six parameters of the JRS scoring system, matching rates of two parameters were higher in the Delta variant group than the non-Delta variant group (pre-vaccination period): age <60 years (77.5% vs 42.2%, P < 0.0001) and no or minor comorbid illness (69.1% vs 57.8%, p = 0.0007). The sensitivity of the diagnosis of atypical pneumonia in patients with COVID-19 pneumonia was significantly higher in the Delta variant group compared with the non-Delta variant group (80.2% vs 58.3%, p < 0.0001). When the diagnostic sensitivity was analyzed for different ages, the diagnostic sensitivities for the Delta variant and non-Delta variant groups were 92.6% and 95.5% for non-elderly patients and 39.1% and 32.5% for elderly patients, respectively. CONCLUSIONS: Our results demonstrated that the JRS scoring system is a useful tool for distinguishing between COVID-19 pneumonia and bacterial pneumonia in the COVID-19 vaccination period, but not before the vaccination period.

INTRODUCTION: The objective of this study was to clarify the clinical differences between nursing and healthcare-associated pneumonia (NHCAP) and community-acquired pneumonia (CAP) due to COVID-19. We also investigated the clinical characteristics to determine whether there is a difference between the variant and non-variant strain in patients with NHCAP due to COVID-19. In addition, we analyzed the clinical outcomes in NHCAP patients with mental disorders who were hospitalized in a medical institution for treatment of mental illness. METHODS: This study was conducted at five institutions and assessed a total of 836 patients with COVID-19 pneumonia (154 cases were classified as NHCAP and 335 had lineage B.1.1.7.). RESULTS: No differences in patient background, clinical findings, disease severity, or outcomes were observed in patients with NHCAP between the non-B.1.1.7 group and B.1.1.7 group. The median age, frequency of comorbid illness, rates of intensive care unit stay, and mortality rate were significantly higher in patients with NHCAP than in those with CAP. Among the patients with NHCAP, the mortality rate was highest at 37.5% in patients with recent cancer treatment, followed by elderly or disabled patients receiving nursing care (24.3%), residents of care facilities (23.0%), patients receiving dialysis (13.6%), and patients in mental hospitals (9.4%). CONCLUSIONS: Our results demonstrated that there were many differences in the clinical characteristics between NHCAP patients and CAP patients due to COVID-19. It is necessary to consider the prevention and treatment content depending on the presence or absence of applicable criteria for NHCAP.

INTRODUCTION: The Japanese Respiratory Society (JRS) scoring system is a useful tool for identifying Mycoplasma pneumoniae pneumonia. Most COVID-19 pneumonia in non-elderly patients (aged <60 years) are classified as atypical pneumonia using the JRS scoring system. We evaluated whether physicians could distinguish between COVID-19 pneumonia and M. pneumoniae pneumonia using chest computed tomography (CT) findings. In addition, we investigated chest CT findings if there is a difference between the variant and non-variant strain. METHODS: This study was conducted at five institutions and assessed a total of 823 patients with COVID-19 pneumonia (335 had lineage B.1.1.7.) and 100 patients with M. pneumoniae pneumonia. RESULTS: In COVID-19 pneumonia, at the first CT examination, peripheral, bilateral ground-glass opacity (GGO) with or without consolidation or crazy-paving pattern was observed frequently. GGO frequently had a round morphology (39.2%). No differences were observed in the radiological findings between the non-B.1.1.7 groups and B.1.1.7 groups. The frequency of pleural effusion, lymphadenopathy, bronchial wall thickening and nodules (tree-in-bud and centrilobular) was low. In contrast to COVID-19 pneumonia, bronchial wall thickening (84%) was observed most frequently, followed by nodules (81%) in M. pneumoniae pneumonia. These findings were significantly higher in M. pneumoniae pneumonia than COVID-19 pneumonia. CONCLUSIONS: Our results demonstrated that a combination of the JRS scoring system and chest CT findings is useful for the rapid presumptive diagnosis of COVID-19 pneumonia in patients aged <60 years. However, this clinical and radiographic diagnosis is not adapted to elderly people.

BACKGROUND: This retrospective study aimed to investigate the short-term surgical outcomes and nutritional status of ileo-colon interposition in patients with esophageal cancer who could not undergo gastric tube reconstruction. METHODS: Sixty-four patients underwent subtotal esophagectomy with reconstruction using ileo-colon interposition for esophageal cancer at the Wakayama Medical University Hospital between January 2001 and July 2020. Using propensity scores to strictly balance the significant variables, we compared treatment outcomes. RESULTS: Before matching, 18 patients had cologastrostomy and 46 patients had colojejunostomy. After matching, we enrolled 34 patients (n = 17 in cologastrostomy group, n = 17 in colojejunostomy group). Median operation time in the cologastrostomy group was significantly shorter than that in the colojejunostomy group (499 min vs. 586 min; P = 0.013). Perforation of the colon graft was observed in three patients (7%) and colon graft necrosis was observed in one patient (2%) in the gastrojejunostomy group. Median body weight change 1 year after surgery in the cologastrostomy group was significantly less than that of the colojejunostomy group (92.9% vs. 88.5%; P = 0.038). Further, median serum total protein level 1 year after surgery in the cologastrostomy group was significantly higher than that of the colojejunostomy group (7.0 g/dL vs. 6.6 g/dL, P = 0.030). CONCLUSIONS: Subtotal esophagectomy with reconstruction using ileo-colon interposition is a safe and feasible procedure for the patients with esophageal cancer in whom gastric tubes cannot be used. Cologastrostomy with preservation of the remnant stomach had benefits in the surgical outcomes and the postoperative nutritional status.

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 This open-label, phase 1 study investigated TAS4464, a potent NEDD8-activating enzyme inhibitor, in patients with advanced/metastatic solid tumors (JapicCTI-173,488; registered 13/01/2017). The primary objective was dose-limiting toxicities (DLTs). Maximum-tolerated dose (MTD) was investigated using an accelerated titration design. Methods The starting 10-mg/m2 dose was followed by an initial accelerated stage (weekly dosing; n = 11). Based on liver function test (LFT) results, a 14-day, 20-mg/m2 dose lead-in period was implemented (weekly dosing with lead-in; n = 6). Results Abnormal LFT changes and gastrointestinal effects were the most common treatment-related adverse events (AEs). DLTs with 56-mg/m2 weekly dosing occurred in 1/5 patients; five patients had grade ≥ 2 abnormal LFT changes at 40- and 56-mg/m2 weekly doses. Further dose escalation ceased because of the possibility of severe abnormal LFT changes occurring. DLTs with weekly dosing with lead-in occurred in 1/5 patients at a 56-mg/m2 dose; MTD could not be determined because discontinuation criteria for additional enrollment at that particular dose level were met. As no further enrollment at lower doses occurred, dose escalation assessment was discontinued. Serious treatment-related AEs, AEs leading to treatment discontinuation, and DLTs were all related to abnormal LFT changes, suggesting that TAS4464 administration could affect liver function. This effect was dose-dependent but considered reversible. Complete or partial responses to TAS4464 were not observed; one patient achieved prolonged stable disease. Conclusions MTD could not be determined due to TAS4464 effects on liver function. Further evaluation of the mechanism of NEDD8-activating enzyme inhibitor-induced abnormal liver function is required. Trial registration number JapicCTI-173,488 (registered with Japan Pharmaceutical Information Center). Registration date 13 January 2017.
