Decreased numbers of gastric, colorectal, lung, and breast cancer surgeries performed in 17 cancer-designated hospitals in Gunma Prefecture of Japan during the COVID-19 pandemic.

PURPOSE: This study aims to clarify the influence of the COVID-19 pandemic on cancer surgery in Gunma Prefecture. METHODS: A total of 9839 cases (1406 gastric cancer, 3569 colorectal cancer, 1614 lung cancer, and 3250 breast cancer) from 17 hospitals in Gunma Prefecture were investigated. We compared the number of surgical cases, proportion of cases found by screening, and cStage at the time of the first visit by month in 2020 and 2021 with those in 2019. RESULTS: The rate of decline in cancer surgery was 8.9% in 2020 compared with 2019 (p = 0.0052). Compared with the same month of 2019, in some months of 2020 and 2021, significant decreases were observed in the number of surgeries for gastric and colorectal cancer, the percentage of surgical cases detected by screening in all four cancers, and the proportion of cancers with a relatively early cStage in gastric and breast cancer. CONCLUSIONS: The number of surgical cases of the four cancer types detected by cancer screening decreased in Gunma Prefecture owing to the influence of the COVID-19 pandemic. Furthermore, for some cancer types, the number of operations performed in patients with early-stage cancer is also decreased.

Successful Endovascular Therapy in an Elderly Patient with Severe Hemorrhage Caused by Traumatic Injury.

An 85-year-old female suffered pelvic fracture, multiple rib fractures, right hemopneumothorax, and blunt abdominal aortic injury in a traffic accident. After transfer to our hospital, transcatheter arterial embolization (TAE) was performed immediately for hemorrhage from the bilateral internal iliac arteries. Enhanced computed tomography (CT) after TAE showed an increase of hematoma and extravasation at the bifurcation of the abdominal aorta. Therefore, emergency abdominal endovascular aortic repair was performed on the same day. On the 3rd day after transfer, metabolic acidosis worsened suddenly, and enhanced CT revealed intestinal necrosis. Emergency surgery for the intestinal necrosis was performed. The patient was transferred to the previous hospital on the 31st day after transfer. Endovascular treatment is useful for elderly patients with severe trauma. However, the preservation and/or reconstruction of the blood flow to important organs should be monitored.

Lung adenocarcinoma with anomalous bronchi and pulmonary veins preoperatively identified by computed tomography.

A 69-year-old woman visited our hospital complaining of right chest pain. Chest computed tomography showed a 55 × 45 mm tumor in the right upper lobe. Bronchoscopy revealed displaced anomalous B 1 and B 2+3 arising from the right main bronchus, and the patient was diagnosed with lung adenocarcinoma by transbronchial lung biopsy from the displaced B 2+3 . Three-dimensional computed tomography with multiplanar reconstruction revealed a displaced anomalous B 1 and B 2+3 branching directly from the right main bronchus, respectively, and abnormal distribution of the aberrant pulmonary vein (V 2 ) descended dorsally to the right main bronchus and emptied into the left atrium. Video-assisted right upper lobectomy with nodal dissection was successfully performed. Attention should be paid to the anomalous bronchus and pulmonary vessels for safer lung cancer operations, especially for video-assisted thoracic surgery.

Prospective multicenter case-control study of telemedicine for home medical care.

We evaluated the safety and efficacy of the combined use of remote medical services for patients with stroke, cancer, neuromuscular diseases, and other conditions, who are being cared for at home. This study was conducted as a part of a multicenter joint trial supported by the Health and Labour Sciences Research Grant for the 'Comparative Study of the home telemedicine in Japan'.

Usefulness of an enhanced recovery after surgery protocol for perioperative management following open repair of an abdominal aortic aneurysm.

PURPOSE: To achieve early recovery and early discharge from the hospital by applying an enhanced recovery after surgery (ERAS) protocol, which is mainly used with colonic surgery, for the perioperative management of open AAA surgery. METHOD: One hundred twenty-seven open AAA surgery cases successfully carried out between 2003 and 2011 were included in this study. The ERAS protocol was used for the cases from April 2008 onward, and we performed a comparison of the conventionally treated cases with ERAS cases regarding the start of postoperative oral consumption, the postoperative hospital stay, and hospitalization medical costs. RESULTS: The time to restarting oral consumption and the postoperative hospital stay were significantly shorter for the ERAS group (n = 52) compared to the conventionally managed group (n = 75); with values of 59 ± 15 and 93 ± 25 h (p = 0.021), 9 ± 3 and 16 ± 5 days (p = 0.001), respectively. The medical costs for the ERAS group were 92 % of the costs of the conventionally managed group. CONCLUSION: Use of the ERAS protocol for the perioperative management of open AAA surgery shortened the time before recommencing oral consumption, the postoperative hospital stay, and reduced the medical costs compared to the conventional approach.

The Effects of Percutaneous Endoscopic Gastrostomy on Quality of Life in Patients With Dementia.

BACKGROUND: To examine the effects of percutaneous endoscopic gastrostomy (PEG) on quality of life (QOL) in patients with dementia. METHODS: We retrospectively included 53 Japanese community and tertiary hospitals to investigate the relationship between the newly developed PEG and consecutive dementia patients with swallowing difficulty between Jan 1st 2006 and Dec 31st 2008. We set improvements in 1) the level of independent living, 2) pneumonia, 3) peroral intake as outcome measures of QOL and explored the factors associated with these improvements. RESULTS: Till October 31st 2010, 1,353 patients with Alzheimer's dementia (33.1%), vascular dementia (61.7%), dementia with Lewy body disease (2.0%), Pick disease (0.6%) and others were followed-up for a median of 847 days (mean 805 ± 542 days). A total of 509 deaths were observed (mortality 59%) in full-followed patients. After multivariate adjustments, improvement in the level of independent living was observed in milder dementia, or those who can live independently with someone, compared with advanced dementia, characterized by those who need care by someone: Odds Ratio (OR), 3.90, 95% confidence interval (95%CI), 1.59 - 9.39, P = 0.003. Similarly, improvement of peroral intake was noticed in milder dementia: OR, 2.69, 95%CI, 1.17 - 6.17, P = 0.02. Such significant associations were not observed in improvement of pneumonia. CONCLUSIONS: These results suggest that improvement of QOL after PEG insertion may be expected more in milder dementia than in advanced dementia.

[A case report of urinary extravasation by renal trauma Grade III successfully managed by percutaneous drainage].

A 30-year-old man was diagnosed with renal trauma Grade a and hospitalized on February 22, 2009. There was no apparent stenosis from the renal pelvis to ureter on pyelography, but computed tomography demonstrated urinary extravasation on March 2. An indwelling drainage catheter was placed percutaneously by an ultrasound-guided approach. An incidental ureter-obstructing blood clot prolonged the indwelling period of the drainage catheter, but we succeeded in avoiding open surgery. Although ureteral stenting might be generally selected for the primary management of traumatic urinary extravasation, it should be remembered that percutaneous drainage is effective in some cases. We consider it important to select the optimal treatment based on an accurate diagnosis of each case.

Prognostic model of stage II non-small cell lung cancer by a discriminant analysis of the immunohistochemical protein expression.

PURPOSE: We aimed to identify the key proteins that influence the prognosis of non-small cell lung cancer (NSCLC) using protein expression profiles of previously known prognostic markers. METHODS: Thirty-one cases of Stage II NSCLC with 5-year follow-up data were selected. Tissue microarrays (TMA) and immunohistochemistry were used to make protein expression profiles of 18 previously reported immunohistochemical prognostic markers and their value in NSCLC was statistically re-evaluated by a discriminant analysis. RESULTS: For the discriminant analysis using marker protein expression profiles, we selected three significant markers, TTF-1, RCAS1 and c-MET, to evaluate each patient's 5-year survival. The requested discriminant function was V = -1.08754 x (RCAS1 score) - 0.83174 x (TTF1 score) + 0.55204 x (cMET score) + 5.46972, and V = 0 served as a cut-off point. The correctness for evaluating a patient's 5-year survival by a discriminant analysis was 87.1%. CONCLUSIONS: A discriminant analysis is thus considered to be a useful statistical method for analyzing the protein expression profiles obtained by combined TMA and immunohistochemical techniques using archival NSCLC tissues. However, the sample size and selection of the marker protein depending on the histology greatly influence the results of a NSCLC study.
