6months) versus the chemotherapy group (3.6months). ORRs were similar between the nivolumab [22.4% of patients (24/107)] and chemotherapy groups [22.2% (24/108); odds ratio, 0.98; 95% CI 0.52-1.87]. DCR was lower in the nivolumab group [41.1% (44/107)] versus the chemotherapy group [66.7% (72/108)]. OS in the exploratory analysis consistently favored the nivolumab group versus the chemotherapy group. Overall, nivolumab demonstrated favorable efficacy and safety versus chemotherapy in the Japanese subpopulation, and the trend was similar to that observed in the overall ATTRACTION-3 ITT population.
Nivolumab represents a new standard second-line treatment option for Japanese patients with advanced ESCC.

This study aimed to establish a simple and useful prognostic indicator for elderly esophageal cancer patients. We designed the modified geriatric nutrition risk index (mGNRI) using the inverse of C-reactive protein (CRP) instead of albumin and compared its prognostic value with those of the GNRI and other indices.
We included 128 patients aged > 65years who underwent esophagectomy for esophageal cancer. We defined mGNRI as (1.489/CRP in mg/dL) + (41.7 × present/ideal body weight) and divided patients into two groups the low-mGNRI (mGNRI < 70, n = 50) and high-mGNRI (mGNRI ≥ 70, n = 78) groups. We retrospectively examined the relationship between mGNRI and long-term prognosis.
The low-mGNRI group had more advanced cancer by stage, higher rates of recurrence, and earlier recurrence than the high-mGNRI group. Univariate analysis identified the following factors as significantly associated with poor overall survival (OS) a lower American society of anesthesiologist performance status (ASA-PS), male gender, CRP-albumin ratio ≥ 0.1, CRP ≥ 1.0, low-mGNRI, tumor depth ≥ T3, Charlson comorbidity index ≥ 2, tumor size ≥ 40mm, and age > 75years. A low-mGNRI, ASA-PS 3, age > 75years, and tumor depth ≥ T3 were independent unfavorable prognostic factors for OS. A low-mGNRI was an independent poor prognostic factor for relapse-free survival. We performed model selection analysis to identify the most clinically useful indices; mGNRI was the best predictive model.
mGNRI in patients with esophageal cancer correlated with early recurrence and was a useful independent prognostic factor.

Fifteen minutes after inserting the chest tube, the patient with right spontaneous pneumothorax was diagnosed with right re-expansion edema by chest radiograph. Although multiple treatments were administered, the patient died. However, the findings from autopsy showed bilateral RPE existed in the decedent but not unilateral RPE. Autopsy, microscopic examination, and clinical records concluded that the cause of death was acute cardiac and respiratory failure due to bilateral re-expansion pulmonary edema following unilateral spontaneous pneumothorax. Bilateral RPE due to a unilateral pneumothorax is quite rare in clinical and forensic practice. To the best of our knowledge, this is the first time that the pathological changes of RPE have been described by gross and microscopic examinations. This case is reported to provide histopathologic references for diagnosis of RPE and indicate that combining death investigation, pathological findings and clinical courses plays a vital role in diagnosis of RPE in forensic pathology.
As an alternative to traditional wire localization, an inducible magnetic seed system can be used to identify and remove nonpalpable breast lesions and axillary lymph nodes intraoperatively. We report the largest single-institution experience of magnetic seed placement for operative localization to date, including feasibility and short-term outcomes.
Patients who underwent placement of a magnetic seed in the breast or lymph node were identified from July 2017 to March 2019. Imaging findings, core needle biopsy, surgical pathology results, and type of surgery were collected. Outcomes included procedural complications, magnetic seed and biopsy clip retrieval rates, and need for additional surgery.
A total of 842 magnetic seeds were placed by nine radiologists in 673 patients and retrieved by six surgeons at six operative locations. The majority of breast lesions were malignant (395/659, 59.9%); 136 seeds were placed for lymph node localization. Smad pathway The overall magnetic seed retrieval rate was 98.6%, whereas twith biopsy clip migration.
Pathologic complete response (pCR) after neoadjuvant chemoradiotherapy (nCRT) is found in 15-20% of patients with locally advanced rectal cancer. A watch-and-wait (W&W) strategy has been introduced as an alternative strategy to avoid surgery for selected patients with a clinical complete response at multidisciplinary response evaluation. The primary aim of this study was to evaluate the efficacy of the multidisciplinary response evaluation by comparing the proportion of patients with pCR since the introduction of the structural response evaluation with the period before response evaluation.
This retrospective cohort study enrolled patients with locally advanced rectal cancer who underwent nCRT between January 2009 and May 2018, categorizing them into cohort A (period 2009-2015) and cohort B (period 2015-2018). The patients in cohort B underwent structural multidisciplinary response evaluation with the option of the W&W strategy. Proportion of pCR (ypT0N0), time-to-event (pCR) analysis, and stoma-free survival were evaluated in both cohorts.
Of the 259 patients in the study, 21 (18.4%) in cohort A and in 8 (8.7%) in cohort B had pCR (p = 0.043). Time-to-event analysis demonstrated a significant pCR decline in cohort B (p < 0.001). The stoma-free patient rate was 24% higher in cohort B (p < 0.001).
Multidisciplinary clinical response evaluation after nCRT for locally advanced rectal cancer led to a significant decrease in unnecessary surgery for the patients with a complete response.
