Food-derived components with physiological effects have been attracting attention in recent years, and studies have comprehensively analyzed these components. In this study, we sought to identify food components with functional properties for the prevention and improvement of metabolic syndrome. We performed a luciferase reporter assay using fatty acid synthase (FAS) and low-density lipoprotein receptor (LDL) receptor gene promoters. Naturally occurring isothiocyanate sulforaphane impaired FAS promoter activity and reduced sterol regulatory element-binding protein (SREBP) target gene expression in human hepatoma Huh-7 cells. Sulforaphane reduced SREBP proteins by promoting the degradation of the SREBP precursor. Furthermore, we screened LDL receptor promoter effectors and observed that extract from sweet cherry peduncles induces LDL receptor gene promoter activity. Several analytical and chemical methods revealed that chrysin 7O-β-D-glucopyranoside in cherry peduncle extract stimulated LDL receptor gene promoter activity. Thus, this comprehensive search for components that alter the expression of genes associated with lipid metabolism led to the discovery of new functions of food components.

Notable advances have recently been achieved in drug therapies for renal cell carcinoma (RCC). Several tyrosine kinase inhibitors (TKIs) and immune checkpoint inhibitors (ICIs) have been approved for metastatic RCC (mRCC). The current first-line treatment for mRCC involves combination therapies using TKIs and ICIs. However, there is no consensus on which TKI+ICI therapy is best or how to select the appropriate therapy for individual patients with RCC. The kidney expresses various metabolic enzymes, including CYP and uridine diphosphate glucose (UDP)-glucuronosyltransferase (UGT). Although information on CYP and UGT expression in the kidney is limited compared to our understanding of liver expression, the main CYP and UGT subtypes expressed at high levels in the kidney are estimated to be CYP2B6, CYP3A5, CYP4A11, CYP4F2, UGT1A6, UGT1A9, and UGT2B7. In RCC, the expression profiles and levels of these enzymes are somewhat altered compared with normal kidney. The main known subtypes of CYP and UGT in RCC are CYP1B1, CYP3A5, CYP4A11, UGT1A6, UGT1A9, UGT1A10, and UGT2B7. High CYP expression has been reported in several cancers, possibly conferring resistance to anti-cancer drugs including TKIs, due to extensive drug metabolism. Additionally, CYP and UGT expression levels may possibly affect cancer prognosis by metabolizing endogenous substrates, regardless of their role in anti-cancer drug metabolism. In this review, I discuss CYP and UGT expression level profiles in RCC based on previously published papers, including ours, and examine possible relationships between these enzyme expression profiles and treatment outcomes for patients with RCC.

The patient is an 81-year-old man. He underwent surgery for pancreatic body cancer in 201X and was followed up every six months with computed tomography (CT) imaging. A CT scan in 201X+5 showed a new nodule in S6 of the right lung. The nodule grew in the latter half of the year and was diagnostically resected on suspicion of being a metastatic lung tumor. A histopathological examination of the resected lung revealed pulmonary cryptococcosis. The postoperative course was uneventful, and the patient was treated with fluconazole 200 mg/day for six months. The patient is currently alive and recurrence-free three years after surgery. Pulmonary cryptococcosis can recur and may be complicated by meningitis. Postoperative antifungal therapy should be considered because of the poor prognosis of meningitis. Postoperative treatment should be performed with caution, especially in patients who are susceptible to infection, have positive preoperative serum cryptococcal antigen levels or have a high standardized uptake value (SUV) max on positron emission tomography (PET)-CT scanning, and are considered to have high fungal loads or activity.

The long-term outcomes of patients with stroke or transient ischemic attack (TIA) after widespread use of direct oral anticoagulants (DOACs) were investigated. Patients with ischemic stroke or TIA admitted between April 2014 and September 2015 were prospectively enrolled and followed for up to 5 years after the index stroke or TIA. Primary outcome measures were any cause of death and stroke recurrence. A total of 555 consecutive patients (323 men; mean age, 75 years; ischemic stroke, n = 520; TIA, n = 35) were analyzed. The follow-up rate was 93%, and the mean follow-up period was 48 ± 20 months. DOACs accounted for 52% of anticoagulants at discharge. During follow-up, 162 patients died, for cumulative mortality rates of 30% (particularly, 53% in cardioembolism) at 5 years. Recurrent stroke occurred in 90 patients, with cumulative risks of stroke recurrence of 19% at 5 years. The 5-year mortality rate remain even after widespread use of DOACs, and further treatment approaches are warranted.

Pyoderma gangrenosum(PG)is a rare skin disorder and its diagnosis is often delayed owing to its wound infection mimicking course. A 50-year-old woman presented to our hospital with multiple liver and bone metastases from breast cancer. A port was created on her right upper arm to administer chemotherapy. Although this treatment was successful, the port wound disrupted 10 months after treatment initiation. An infection was suspected, the port was removed, and chemotherapy was discontinued. However, another ulcer with necrotic tissue was observed in the right inguinal region. Skin biopsy revealed dense infiltration of neutrophils into the epidermis and dermis. The patient was administered prednisolone 30 mg/ day, and both wounds recovered. This case shows that, when skin necrotic ulcers are observed in patients with cancer, PG must be considered as a differential diagnosis.

When respiratory failure occurs due to intractable pleural effusion, frequent thoracentesis is necessary. We herein report a patient who underwent diaphragmoplasty and pleuroperitoneal shunt for refractory pleural effusion after cardiac surgery. The patient was an 82-year-old man with a history of tricuspid valve replacement for tricuspid regurgitation 9-years ago. Heart failure recurred due to prosthetic valve dysfunction, and he underwent repeat tricuspid valve replacement. Postoperatively, he had right diaphragmatic nerve palsy and required frequent thoracentesis for persistent dyspnea on exertion and pleural effusion. He underwent thoracoscopically-assisted right diaphragmatic plication and right pleuro-peritoneal shunting using a Denver shunt. Dyspnea subsided, and pleural effusion disappeared. Diaphragmatic plication and pleuro-peritoneal shunting using a Denver shunt for refractory pleural effusion with diaphragm elevation may improve patient's quality of life.

A 41-year-old asymptomatic male with no significant medical history had a heterogenous cystic tumor with a diameter of 5.1 cm containing fatty density in the anterior mediastinum and a nearby homogeneous enhancing nodule with a diameter of 2.0 cm were observed on chest computed tomography( CT). A malignant teratoma with mediastinal lymph node metastasis was suspected preoperatively. The tumor was completely removed via median sternotomy, with concomitant resection of the lung, pericardium, and right phrenic nerve. Postoperative pathological examination revealed a large mature cystic teratoma, 6.0 cm in diameter, and a small nodule, 3.7 cm in diameter, diagnosed as stageⅠ, type B2 thymoma. The postoperative course was uneventful, with no recurrence 30 months later. The simultaneous occurrence of mature teratoma and stageⅠthymoma is extremely rare. When suspecting a teratoma with small satellite nodules preoperatively, consideration of concurrent small thymoma is suggested.

In recent years, percutaneous coronary intervention (PCI) has been performed for left main trunk lesions and severe three-vessel lesions, which were previously considered indications for coronary artery bypass grafting( CABG). As a result, more patients with poorer general conditions or vascular characteristics are being considered for CABG. In the current era of PCI, surgeons are required to achieve high bypass graft patency and to perform anastomosis according to the coronary artery lesion and the characteristics of the bypass graft. There are two types of distal anastomosis for bypass grafts:end-toside and side-to-side. End-to-side anastomosis is a commonly used method in many institutions. Because the cuff-like anastomotic morphology of the end-to-side anastomosis has been reported to have a hydrodynamic advantage in blood flow at the anastomotic site, end-to-side anastomosis needs to be cuff-shaped. On the other hand, side-to-side anastomosis is reported to be easier to anastomose even when there is a mismatch in vessel diameter between the coronary artery and the bypass graft because the coronary artery incision and the bypass graft incision are more easily aligned in plan. In addition, extensive revascularization( onlay-patch grafting) is used for diffuse lesions in the coronary arteries. This section focuses on each method of coronary anastomosis.

A 36-year-old woman presented to our hospital with a complaint of melena. Examinations revealed type 3 gastric cancer with left supraclavicular lymph node(Virchow's node)and para-aortic lymph node(PAN)metastases. The patient was treated with S-1 and CDDP combination chemotherapy. After 2 courses of chemotherapy, the lymph node metastases were significantly reduced. Subsequently, a total gastrectomy with D2 plus PAN dissection was performed. Histopathological examination revealed the complete absence of cancer cells in both the primary lesion of the stomach and all dissected lymph nodes. No additional surgery or radiation therapy was performed for Virchow's node metastasis. Postoperatively, she received S-1 chemotherapy for 2.5 years. She remains well 9.5 years after the surgery, without any evidence of recurrent disease.

Preoperative embolization(POE)of intracranial meningioma is performed worldwide. Although clear evidence of the effectiveness of POE has not been reported in the literature, the technique plays an important role in open surgery, especially for large or skull base meningiomas. The purposes of embolization include: 1)induction of tumor necrosis, resulting in a safer operation, 2)reduction in intraoperative bleeding, and 3)decrease in operative time. Knowledge of the functional vascular anatomy, embolic materials, and endovascular techniques is paramount to ensure safe embolization. Our standard procedure is as follows: 1)embolization is performed several days before open surgery; 2)in cases with strong peritumoral edema, steroid administration or embolization may be performed immediately prior to surgery; 3)patients undergo the procedure under local anesthesia; 4)the microcatheter is inserted as close as possible to the tumor; 5)particulate emboli are the first-line material; 6)embolization is occasionally performed with N-butyl cyanoacrylate(NBCA)glue; and 7)if possible, additional proximal feeder occlusion with coils is performed. The JR-NET study previous showed the situation regarding intracranial tumor embolization in Japan. Endovascular neurosurgeons should fully discuss the indications and strategies for POE with tumor neurosurgeons to ensure safe and effective procedures.

The patient, an 83-year-old woman, was diagnosed with ER- and PgR-positive left breast cancer(T2N0M0, Stage ⅡA) at the age of 68. At the time, she underwent preoperative chemotherapy followed by Bp+Ax and postoperative radiotherapy to the conserved breast. She also received endocrine therapy as adjuvant therapy. At the age of 73, she underwent radiotherapy for multiple bone metastases and left axillary lymphadenectomy due to left axillary lymph node recurrence. After surgery, she received 4 regimens of endocrine therapy over a period of 5 years and 1 month for bone metastases. At the age of 79, S-1 was administered for pulmonary metastasis which continued for the next 2 years and 8 months. At the age of 81, palbociclib+letrozole were administered for 1 year and 8 months owing to the progression of bone metastases. At the age of 83, she developed liver metastases and was administered ethinyl estradiol, starting at 1.5 mg/day and continued at a reduced dose of 0.5 mg/day for 9 months. The reduction in tumor markers after treatment initiation was rapid, and there were no serious adverse events. Ethinyl estradiol was useful for maintaining QOL in this elderly patient with recurrent breast cancer.

A 42-year-old man visited our hospital complaining of secondary infertility. An abdominal ultrasonography screening incidentally revealed a protruding lesion in the bladder. As the lesion extended from the prostatic urethra and bladder neck, there was a possibility of ejaculation dysfunction after resection of the lesion. Therefore, with the patient's informed consent, sperm cryopreservation was conducted for fertility preservation, and subsequently histological examination was performed by partial transurethral resection of bladder tumor. The pathological findings were proliferative cystitis including all three subtypes (glandularis, cystica, and papillary). Cyclooxygenase-2 immunostaining was positive in cytoplasm; weakly positive in cystic and papillary lesions, and strongly positive in glandular lesions. According to a literature review of massive proliferative cystitis, the patient was the 77th case in Japan. Novel postoperative immunological pharmacotherapies with cyclooxygenase-2 inhibitors have been introduced in recent years.

In promoting the community-based comprehensive care system, designated cancer hospitals are required to provide decision- making support for treatment and care in the face of increasingly sophisticated and diverse treatments, to promote hospitalization and discharge support to shorten the length of hospital stay, and to implement multidisciplinary cooperation for coordination of treatment and care due to the increasing number of elderly and multi-morbidity cancer patients. However, it is difficult at present to link and integrate designated cancer hospitals, which are required to provide cancer treatment in each secondary medical care area, and community comprehensive care systems, which provide medical care and care to support daily life and autonomy and independence of patients and their families in the patients' living areas. In the future, through the promotion of networking and educational activities for healthcare professionals, as demonstrated in previous studies, it will be necessary to establish a system in which cancer treatment and community-based comprehensive care systems are linked to provide high-quality medical care and care to cancer patients.

Muscle biopsy for inflammatory myopathies facilitates the direct observation of muscle pathology at the site of inflammation by obtaining a small amount of tissue for pathological diagnosis. In clinical settings, muscle pathology derived from a muscle biopsy provides information limited to the tissue sampled. Thus, clinical information must supplement this to ascertain whether the obtained muscle pathology aligns with patient clinical presentation of myositis. This paper discusses considerations for effectively utilizing muscle biopsy in diagnosing inflammatory muscle diseases in clinical practice. Additionally, we briefly explore interpreting the pathological findings of myositis obtained from biopsy samples.

The superior petrosal sinus and petrosal vein are important drainage routes for the posterior cranial fossa, with some variations and collateral vessels. An anterolateral-type tentorial dural arteriovenous fistula, which occurs around the petrosal vein, often develops aggressive symptoms due to venous reflux to the brainstem and cerebellum. Neuroendovascular treatment of this fistula is usually challenging because transarterial embolization has a high risk and indications for transvenous embolization are limited. In the cavernous sinus and transverse sinus/sigmoid sinus dural arteriovenous fistulas, venous reflux to the petrosal vein is dangerous, and a treatment strategy with the occlusion of the petrosal vein is indispensable. Furthermore, attention should be paid to venous approaches through the superior petrosal sinus.

Background: The novel coronavirus disease(corona virus disease 2019: COVID-19)has calmed down worldwide, and the severity of the disease is decreasing. On the other hand, due to the emergence of strain mutations, the number of infected people shows a wavy course. I have experienced a case of gastric cancer that underwent chemotherapy including an immune checkpoint inhibitors(ICI) early after COVID-19, so I will report it including a discussion., Case: A 71-year-old man. The patient visited our hospital with a chief complaint of stomach discomfort, and gastrointestinal endoscopy revealed advanced gastric cancer accompanied by narrowing of the gastric lumen. The histopathological examination showed a poorly differentiated adenocarcinoma. A CT scan of the chest and abdomen showed thickening of the entire gastric wall, indicating the presence of enlarged adjacent lymph nodes and infiltration into adjacent organs. No other obvious distant metastases were observed. Staging laparoscopy was performed, it revealed infiltration of the posterior wall of the stomach into the celiac artery and anterior surface of the pancreas. We determined that curative resection would be difficult. As a result of planning chemotherapy for locally advanced gastric cancer, the patient contracted COVID-19 due to a hospital- acquired infection. The patient's COVID-19 infection was managed with supportive care alone without severe complications, and they recovered within the course of treatment. Two weeks after the onset of the infection, chemotherapy(FOLFOX+ Nivo)was initiated. The patient completed up to 9 courses of chemotherapy, and the treatment response was determined to be stable disease(SD). Due to a tendency of stenosis in the gastric lumen, the possibility of future dilation procedures was considered. As a result, the patient underwent second-line chemotherapy with a combination of wPTX+RAM. After completing 1 course of treatment, the patient developed drug-induced interstitial pneumonia, which was managed with intensive care and steroid pulse therapy, resulting in improvement. There was progression of gastric lumen stenosis, and an endoscopic dilation procedure/stent placement was performed. Subsequently, there was a rapid increase in malignant ascites and a decline in activities of daily living(ADL), leading to palliative care. Unfortunately, the patient succumbed to cancer-related complications 10 months after the diagnosis., Discussion: In this case, the serial antibody titers of COVID-19 also indicated the sustained effectiveness of the multi-drug combination chemotherapy. The treatment course suggests a suspicion of drug-induced interstitial pneumonia due to PTX/RAM, but the long-term imaging follow-up implies that ICI may be the cause. When using ICI, COVID-19 infection alone may pose a potential risk factor.

Calcified amorphous tumor (CAT), a non-neoplastic tumor, is rare. Histopathologic features are the presence of calcified nodules in an amorphous background of fibrin. CAT is reported to be associated with renal dysfunction or hemodialysis, and possibly causes cerebral embolism. We report a case of CAT diagnosed after stroke. A 58-year-old male with a 2-year history of hemodialysis was diagnosed with an acute stroke, and was treated medically. Paralysis promptly improved, but transthoracic echocardiography revealed a tumor attached to the posterior mitral leaflet and dense mitral annular calcification. To prevent embolism due to the large tumor, we performed resection of the tumor. Pathological findings showed calcifications surrounded by amorphous fibrous tissue, indicating CAT. Postoperative course was uneventful.

A man in his 50s was stabbed deeply in the back with a knife and brought to the emergency room. He was found to have a significant left hemopneumothorax. He was planned to undergo hemostatic surgery under general anesthesia. However, shortly after the change in a right lateral decubitus position, he experienced ventricular fibrillation. Hemostasis of the intercostal artery injury, the source of bleeding, and suture of the injured visceral pleura were performed under extracorporeal membrance oxgenation( ECMO). Although sinus rhythm was resumed, when positive pressure ventilation was applied to the left lung for an air leak test, ST elevation on the electrocardiogram and loss of arterial pressure occurred. A transesophageal echo revealed air accumulation in the left ventricle. It was determined that air had entered the damaged pulmonary vein from the injured bronchi due to the stab wound, leading to left ventricular puncture decompression and lower left lower lobectomy. Subsequently, his circulatory status stabilized, and ECMO was weaned off. He recovered without postoperative neurological deficits postoperatively. The mortality rate for chest trauma with systemic air embolism is very high. In cases of deep lung stab wounds, there is a possibility of systemic air embolism, so treatment should consider control of airway and vascular disruption during surgery.

The aim of this study was to investigate the short-term outcomes of surgery for colorectal cancer(CRC)in the elderly aged over 90 years old. We retrospectively analyzed 1,043 patients with stage Ⅰ-Ⅳ CRC who underwent curative surgery in our institutions between 2013 and 2022. The patients were divided into the super older(aged ≥90 years, 20 patients) and non-super older groups(aged 80-89 years, 243 patients). The short-term outcomes were compared between the 2 groups. There were no significant differences in tumor location, stage, surgical approach, duration of operation and blood loss. The incidence of severe postoperative complications did not differ between the 2 groups. In conclusion, our study suggested that surgery for colorectal cancer could be as safely performed in super elderly patients as in non-super elderly patients.

A 61-year-old woman was referred for further evaluation of an intracystic nodule in her left upper lung. Computed tomography( CT) showed a 15 mm nodule in a pulmonary cyst adjacent to aortic arch and mediastinum. Fluorodeoxyglucose-positron emission tomography (FDG-PET)-CT showed little uptake of FDG in the lesion. No abnormality was found in the bronchoscopy findings. On imaging findings, the possibility of pulmonary aspergilloma was considered, but the serological findings were inconsistent, and surgical resection of the lesion was performed for both diagnosis and treatment. The final pathohistological diagnosis was well differentiated liposarcoma. No adjuvant therapy was performed and the patient has been well without recurrence for 2 years after the surgery. We report a rare case of well differentiated liposarcoma of a lung mimicking pulmonary aspergilloma.

Background: Lung segment anatomy is complex and difficult for medical students to comprehend, so education is a challenging issue. Three-dimensional (3D) models may be a more effective teaching tool for medical students. We evaluated the usefulness of 3D models in education for segmentectomy., Methods: Sixty-six students who participated in clinical training for thoracic surgery from November 2020 to March 2022 were included in the study. Computed tomography (CT) images, 3D-CT images, and 3D models were used to investigate students' level of understanding for each lung segment. Levels of understanding were assessed using a questionnaire administered using the interview method. The results of the questionnaire were tabulated and analyzed using the Kruskal-Wallis test., Results: The response rate was 100%. Comprehension scores for all questions were highest for 3D models, followed by 3D-CT and CT. These results suggest that use of a 3D entity model may have a high educational effect., Conclusion: Although it is unclear whether students' comprehension was directly related to their understanding of correct anatomy, our results suggest that 3D models may be an effective way for medical students to understand lung segmentectomy.

Several studies have reported the importance of preoperative simulations. This report describes the methods and utility of neuroendovascular treatment using a three-dimensional(3D)-printed hollow cerebral aneurysm model. This model was created using a stereolithography apparatus-type 3D printer with digital imaging and communications in medicine data from 3D digital subtraction angiograms. The 3D model was used to perform preoperative simulations of microcatheter placement in aneurysms, microguidewire manipulation, and stent deployment. We performed each simulated procedure during surgery. The hollow cerebral aneurysm 3D model can also be used as a training model for surgical trainees. Preoperative simulation using a high-precision hollow cerebral aneurysm model created using 3D printers enables the discussion of specific treatment strategies for each case, including new devices and device sizes, and is expected to develop into "tailor-made medicine" in the future, contributing to safe and reliable treatment implementation.

We report a case of bioprosthetic valve dysfunction and acute aortic valve regurgitation. The case was a 75-year-old female who had sudden onset chest pain. ST-segment depression in several leads on electrocardiogram( ECG) suggested acute coronary syndrome. Coronary angiography showed no significant stenosis in coronary arteries. Transesophageal echocardiography revealed severe aortic regurgitation, suggesting that angina was caused by myocardial ischemia associated with acute aortic regurgitation. She was diagnosed as having bioprosthetic valve dysfunction, and underwent redo aortic valve replacement. One leaflet of the bioprosthetic valve was torn along the stent post and caused bioprosthetic valve dysfunction. Failed bioprosthetic valve was removed and replaced by a mechanical valve.

We report a 27 years-old previously healthy male admitted to a psychiatric hospital because of abnormal behavior. He was suspected meningoencephalitis with fever, abnormal sweating, muscle tone, confusion, and introduced to the neurology department of our hospital. After admission, increasing convulsions and apnea attack required mechanical ventilation therapy. Anti-N-methyl-D-aspartate( NMDA) - receptor encephalitis was diagnosed based on positive (20-fold) anti-NMDA antibody in cerebrospinal fluid examination. An enhanced chest computed tomography (CT) showed a 43 mm cystic mass with calcification of the anterior mediastinum. He underwent the tumor resection under median sternotomy on the 18th hospital day. The plasmapheresis and steroid therapies were treated after the operation. The consciousness level gradually improved, the patient was withdrawn from the respirator on the post operative day( POD) 35, and transferred to a rehabilitation hospital on POD 60. The pathological result was mature teratoma. However, no specific findings such as inflammatory cell infiltration into nerve components were observed. Anti-NMDA receptor encephalitis was established by Dalmau in 2007 as encephalitis associated with ovarian teratoma. It presents mainly in young adult women with psychiatric symptoms, and requires mechanical ventilation management due to disturbance of consciousness, convulsions, and central hypoventilation in a short period of time. It presents severe symptoms in the acute phase and shows a unique clinical finding with a good prognosis even though it shows a protracted course. Treatment requires prompt tumor detection and early resection, as well as methylprednisolone (mPSL) pulse, plasmapheresis, and high-dose gamma globulin therapy. It is a neurological disease that requires emergency response, and the understanding and prompt response of related departments is important.

Radical cystectomy for locally advanced colorectal cancer with urinary bladder invasion significantly reduces the quality of life in exchange for a cure. We performed preoperative chemotherapy with FOLFOXIRI plus bevacizumab for 3 patients with locally advanced colorectal cancer with urinary bladder invasion to avoid radical cystectomy and to achieve local control for urinary bladder preservation. Grade 3 neutropenia was observed in 2 patients as an adverse reaction to the preoperative chemotherapy, but all 3 patients showed good tumor regression. All 3 patients underwent laparoscopic high anterior rectal resection and partial cystectomy, and all were able to undergo R0 resections with urinary bladder preservation. One patient had anastomotic leakage as a postoperative complication. One patient had local recurrence in the urinary bladder, and 2 had recurrence with peritoneal dissemination during their postoperative courses. Preoperative chemotherapy(FOLFOXIRI plus bevacizumab)for locally advanced colorectal cancer with urinary bladder invasion is considered to be a useful treatment option because of its potential for tumor shrinkage and bladder preservation.

Aim: To reveal the characteristics and the oral function of institutionalized frail older adults and the factors contributing to frailty., Methods: This multicenter, cross-sectional study included 214 patients. A questionnaire was administered to registered dietitians from these institutions. Sex, age, height, weight, grip strength, calf circumference, level of care need, FRAIL-NH, MNA ® -SF, dysphagia, food form and water thickening, number of medications, major diseases, comorbidities, independence in daily living of older people with dementia, use of medication with dry mouth, nutritional care issues (malnutrition-related problems) by multiple occupations in Nutrition and Eating Swallowing Screening, Assessment and Monitoring, and nine oral-related items were evaluated., Results: One hundred six patients (49.5%) were classified as frail, 75% of the patients were women, and the mean BMI was 19.7 kg/m 2 . Older adults with frailty were characterized by high care needs, malnutrition, multiple comorbidities, multiple medications, eating and swallowing disorders, the requirement of feeding assistance, and the need to adjust the shape of meals and fluids. The multivariable OR (95%CI) for "choking and residue problems" was 1.81 (1.20-2.73), while that for "dietary concentration problems" was 4.28 (2.10-8.74)., Conclusion: Caregivers must maintain posture and provide meal assistance. Professionals in various occupations must adjust the proper food form and medication content. Meal times must be examined in consideration of the times at which drugs will be most effective. Oral care must be provided, and an environment must be created to help the subject concentrate. Focusing on problems of choking, residue, and concentration on meals is expected to improve frailty, aspiration pneumonia, and the prognosis of institutionalized older adults.

A 62-year-old man presented with fever and anorexia since July X. Initial treatments were rendered ineffective, and due to altered consciousness and vomiting, he was referred to our hospital. On admission, he manifested delirium, drowsiness, and disorientation. While blood tests were normal, gastroscopy identified a type 3 tumor in his lower gastric body, later diagnosed as a poorly differentiated adenocarcinoma. Immunohistochemistry demonstrated negative human epidermal growth factor receptor 2 and positive programmed death-ligand 1 expression with a combined positive score ≥5. Furthermore, a positive Epstein-Barr virus-encoded small RNA in situ hybridization result was noted. Abdominal contrast-enhanced CT and PET-CT scans demonstrated multiple lymph node metastases around the stomach and liver, establishing the diagnosis of stage IVB gastric cancer (T4aN2M1). Brain magnetic resonance imaging (MRI) demonstrated enhanced lesions in the brainstem, cerebellar sulci, and right occipital lobe. Although cerebrospinal fluid cytology was negative for malignancy, the clinical symptoms and MRI findings confirmed leptomeningeal carcinomatosis (LMC). The patient underwent radiotherapy for LMC (total of 30Gy in 10 fractions), followed by combination therapy with a nivolumab and SOX regimen. Posttreatment, the LMC symptoms resolved;however, he experienced grade 3 immune-related adverse events related to liver dysfunction. Nivolumab was discontinued, and with steroid administration, the adverse events improved. Imaging evaluations posttreatment showed gastric tumor reduction and the absence of LMC. After 7 cycles, nivolumab was reintroduced, with no liver dysfunction recurrence noted through 15 cycles. Endoscopic examination 1 year postonset demonstrated that the gastric tumor had scarred, and MRI showed no signs of LMC recurrence. In 5-8% of solid tumors, LMC complications are present, resulting in limited treatment options and poor prognosis. Recent reports suggest the potential of immune checkpoint inhibitors in treating intracranial metastasis from solid tumors. In Japan, nivolumab was approved for gastric cancer treatment in 2017 and for first-line therapy in combination with chemotherapy since 2021. We report a case in which radiotherapy and chemotherapy combined with nivolumab provided durable control of LMC originating from gastric cancer for more than 1 year.

Purpose: This study investigated the factors associated with oral frailty among community-dwelling older adults. In particular, we compared the factors between individuals in the young-old and old-old groups and clarified the differences between the two groups., Methods: We measured the basic attributes, body composition, grip strength, gait function, oral function, cognitive function, and daily living function using the Kihon checklist in older people living independently in T City, Aichi Prefecture. The risk of oral frailty was assessed using the Oral Frailty Screening and Evaluation Form (OFI-8), and the measurement results were compared between two groups: those with and those without risk. To identify the factors associated with oral frailty, we performed a multivariate analysis with the risk of oral frailty as the dependent variable and a univariate analysis separately for the young-old and old-old groups., Results: The mean age of the 100 subjects was 76.6±4.6 years old. Forty-four subjects were at risk of oral frailty, and 55 subjects were not at risk. The high-risk group had significantly higher rates of polypharmacy, depression, and a slow walking speed than the no-risk group. The risk factors associated with oral frailty were living alone, polypharmacy, and depression. The risk factors for oral frailty were a poor ambulatory function in the young-old and a poor ambulatory function, decline in the cognitive function, and depression in the old-old., Conclusions: The results of this study suggest that the risk factors for oral frailty differ between older individuals in the young-old and old-old groups and that age-appropriate support is necessary to prevent oral frailty in older people.

Chylous ascites is a rare post operative complication after gastrectomy, which commonly occurs in early postoperative period. Here, we successfully treated a patient with unresectable gastric cancer who occurred chylous ascites 9 months after first surgery and underwent laparoscopic surgery for chylous ascites. Since prolonged chylous ascites may cause malnutrition, surgical treatment should be considered for refractory chylous ascites.

Purpose: The present multicenter randomized controlled trial explored the effectiveness of a person-centered care program (intervention group) and a dementia-type-specific program (control group) for nurses in acute-care hospitals., Methods: Seven hospitals in Prefecture A were randomly allocated to two groups (an intervention group and a control group), and a study of these groups was conducted from July 2021 to January 2022., Results: A total of 158 participants were included in the study: 58 in the control group and 100 in the intervention group. In a comparison of assessment values immediately after the course, three months later, and six months later for both the intervention and control groups, "expertise in dementia nursing," "medical expertise in dementia, " and "confidence in nursing older people with dementia" were all significantly higher than before the course. Significant improvements in the intervention group's "knowledge of dementia" and "sense of dignity" on the ethical sensitivity scale were found immediately after the course compared to baseline, three months later, and six months later and were also significantly greater than the control group in terms of the amount of change. In the control group's "unique care tailored to cognitive function and the person," there were significant improvements in the ratings immediately after the course and three and six months after the course compared to baseline, with significantly greater amounts of change than in the intervention group., Conclusion: The person-centered care program for nurses led to improvements in the knowledge about dementia and awareness of the dignity of ethical sensitivity. In addition, the type of dementia program had a significant influence on medical knowledge and unique care tailored to the cognitive function and the individual patient. Further outcome evaluations of physical restraint rates as a quality of care in nursing practice are needed.

We conducted a comprehensive survey of Foods with Function Claims (FFC) submitted from April to August 2022 to examine the scientific reliability of the systematic review (SR), which is the basis for functional claims. The results of the review of 611 functional claims for 398 products showed that there were 121 functionally active substances and 87 health claims (Hc) that were labeled, with some functionally active substances having multiple functions. SRs, meta-analyses, and clinical studies were submitted as the basis of functionality for 87%, 10%, and 3% of the reports, respectively. Of these SRs, 39% of the SRs included a single paper. In 67% of the SRs with a single paper included, some of the authors of the included paper and the person who conducted the SR had the same affiliation, which raises concerns about conflicts of interest. The median of clinical trial participants in papers included for SR was relatively small, 38, and the smallest total number of SRs was 6. Thus, it was shown that there are many SRs for FFC that are based on only a single paper or a small-scale clinical trial and that lack reliability as scientific evidence.

The patient was a 61-year-old man with a diagnosis of carcinoma of the pancreatic head. Abdominal computed tomography( CT)showed no distant metastasis, and he underwent subtotal stomach-preserving pancreatoduodenectomy. Immediately after surgery, he received liver perfusion chemotherapy with 5-fluorouracil followed by systemic gemcitabine. Eighteen months after surgery, CT revealed liver metastasis in the S6 segment, and partial hepatectomy was performed. The pathological diagnosis was liver metastasis of pancreatic cancer. Postoperatively, the patient was treated with gemcitabine and S-1 therapy for 1 year and then switched to S-1 monotherapy for about 6 months. Four years after the initial surgery, CT showed 2 metastases in the right lung. After 2 months of S-1 monotherapy, wedge resection of the upper and lower lobes of the right lung was performed. Gemcitabine and nab-paclitaxel therapy were administered, after the metastasectomy, but pleural dissemination appeared on CT 5 years after the initial surgery. Modified FOLFIRINOX therapy was started and continued for 8 months, but CT revealed further disseminated lesions in the diaphragm. Palliative irradiation was provided, but the disease gradually progressed. After multidisciplinary treatment, the patient survived for 6 years and 3 months after the initial surgery.

A 28-year-old female patient with no particular medical history had a sore throat seven days before admission. Subsequently, she developed malaise, right abdominal pain, and a fever of 38°C and visited our hospital. A blood test revealed a mild inflammatory response and elevated liver enzymes, and she was admitted to the hospital for detailed examination and acute liver injury treatment. Various viral tests and autoantibody measurements revealed elevated Epstein-Barr virus (EBV) immunoglobulin M and negative EB nuclear antigen antibodies. Therefore, she was diagnosed with primary infectious mononucleosis-associated EB viral hepatitis. Abdominal computed tomography upon admission revealed swollen lymph nodes around the stomach;thus, esophagogastroduodenoscopy (EGD) was performed. A histopathological examination revealed severe lymphocytic infiltration, and EB encoding region in situ hybridization demonstrated that 10-20% of the lymphocytes were EBV-infected. Drip and rest treatment improved the patient's liver enzymes, and her symptoms resolved. Repeat EGD after two months revealed improved gastric erosions. Here, we report a case of EBV-associated gastritis that was discovered due to perigastric lymphadenopathy accompanied by infectious mononucleosis. This report includes a review of the literature because a few studies reported EBV-associated gastritis.

Congenital protein C (PC) deficiency is one type of hereditary thrombosis. Patients with hereditary thrombosis are at high risk for thrombosis in the perioperative period, but a standard management strategy has not been established. Here we report a case of perioperative management of a fracture in a child with homozygous congenital PC deficiency. The patient was a 3-year-old boy who was diagnosed with congenital PC deficiency at birth. He sustained a traumatic supracondylar fracture of the right humerus and underwent emergency surgery. To prepare for open surgery for fixation of the fracture, warfarin was discontinued, and an activated PC (APC) concentrate was used in combination with vitamin K antagonism. However, warfarin was administered during the scheduled nail extraction because the operation was minimally invasive. No thrombotic or bleeding complications occurred in either operation. In emergency surgery in patients with congenital PC deficiency, the combination of vitamin K and APC concentrate is considered a maintenance option for PC deficiency. Postoperative PT-INR control was difficult in our patient due to the administration of vitamin K and withdrawal of warfarin, and this issue must be addressed in the future. Further case experience is desirable to standardize perioperative management.

Environmental electrophiles modify thiol groups of proteins in organs, disrupting cellular functions carried out by the modified proteins and increasing the risk of various diseases. The transcription factor NF-E2-related factor 2 (Nrf2) plays a crucial role in detoxifying electrophiles by forming glutathione adducts and subsequently excreting them into extracellular spaces. Supersulfides such as cysteine persulfides (CysSSH) produced by cystathionine γ-lyase (CSE) capture environmental electrophiles through sulfur adduct formation. However, the Nrf2 and CSE contributions to blocking environmental electrophile-mediated toxicity have yet to be evaluated. Therefore, we assessed the individual and combined roles of Nrf2 and CSE in suppressing toxicity induced by environmental electrophiles using Nrf2 knockout (KO), CSE KO, and Nrf2/CSE double KO (DKO) mice. Our findings indicate that CSE/Nrf2 DKO mice are more sensitive to environmental electrophiles compared to their single KO counterparts, highlighting the distinct mechanisms through which both pathways mitigate the toxic effects of reactive electrophiles. Moreover, diverse metabolites produced by symbiotic gut bacteria in the human body are known to exert various effects on host organ functions beyond the intestinal tract. We observed reduced blood supersulfide levels in mice lacking gut microflora compared to normal mice. Furthermore, we identified intestinal bacteria belonging to the families Ruminococcaceae and Lachnospiraceae as high CysSSH-producing bacteria. This suggests that the gut microbiota serves as a source of in vivo supersulfide molecules. These findings suggest that supersulfide derived from gut bacteria may act protectively against environmental electrophilic exposure in the host.

Already a rare presentation in patients with systemic mastocytosis (SM), chronic diarrhea is even rarer in those with mast cell leukemia (MCL), a subtype of SM. We present a case to illustrate the utility of lower gastrointestinal endoscopy with histological examination in the diagnosis of MCL in a patient with chronic diarrhea. A woman in her 70s presented with persistent diarrhea. Colonic mucosal biopsy with lower gastrointestinal endoscopy revealed mast cell proliferation, which led to the diagnosis of mastocytosis. Elevated serum tryptase levels and mast cell proliferation in the bone marrow and lymph nodes led to the diagnosis of MCL, a subtype of SM, based on the presence of >30% mast cells in the bone marrow.

Herein, we report the case of a 7-year-old girl with a history of atopic dermatitis because of infancy. Her grandfather grew Egoma (Perilla frutescens), and her family frequently consumed food items prepared using Egoma; however, she never consumed them because she did not enjoy these food items; she experienced vomiting, facial swelling, and oral discomfort upon ingesting Egoma during school lunch for the first time. Her food oral challenge test was positive, as well as a skin-prick test with sesame powder. Egoma antigen protein was extracted and reacted with patient serum by immunoblotting, which detected a positive band of approximately 26kDa. She was brought up in an environment with high exposure to Egoma; hence, she most likely developed an allergy to Egoma because of percutaneous sensitization. This is the first time an Egoma allergen analysis has been conducted in Japan, and we consider it to be a valuable case.

Background and Aims: Bronchial thermoplasty (BT) is a bronchoscopic treatment for adult patients with moderate to severe asthma. A systematic review was conducted to examine the efficacy of this treatment., Methods: Randomized controlled comparing BT to a control in adult patients with moderate to severe asthma were added to the previously conducted systematic review. Literature published prior to July 2022 was selected., Results: Four trials were included in this study. BT resulted in significant improvement in quality of life. However, no significant difference in asthma control was observed. Moreover, the incidence of severe adverse events during the treatment period was increased by BT. Furthermore, BT did not improve lung function, increase withdrawal from oral corticosteroids, reduce frequency of rescue medication usage, or increase the number of symptom-free days., Conclusion: From a risk-benefit perspective, there is insufficient evidence to support a recommendation of BT in adult patients with moderate to severe asthma.

A 19-year-old female, normal at birth, grew up without neck movement when getting up. She needed a handrail to climb stairs since the age of 10 years old, and walked slowly since the age of 16 years old. Neurological examination revealed loss of deep tendon reflexes, decreased vibratory sensation, weakness of distal muscles of the lower extremities, and weakness of mainly cervical trunk muscles suspected to be due to myopathy. Nerve conduction studies suggested axonal polyneuropathy, and needle EMG showed short duration MUP, myotonic discharge, and rimmed vacuoles on muscle biopsy. Genetic analysis revealed a previously reported pathological mutation (p.P209L, heterozygous) in Bcl2-Associated Athanogene 3 (BAG3), and a diagnosis of MFM6 was made. P209L is a poor prognosis myopathy that develops in childhood and is associated with cardiomyopathy. P209L is a solitary myopathy associated with axonal neuropathy and characterized by apex foot contracture and weak neck to trunk flexion. This disease is suspected in young-onset neuromyopathy.

A 72-year-old woman presented with obstructive jaundice. Computed tomography revealed a 12-mm low-density mass in the head of the pancreas. She was diagnosed as having pancreatic cancer by endoscopic ultrasound-guided fine-needle aspiration. She received gemcitabine plus nab-paclitaxel as preoperative chemotherapy. After 2 courses, hepatoduodenal lymph node metastasis appeared and was accompanied by increased tumor marker levels. The regimen was changed to modified FOLFIRINOX. After 5 courses, the lymph node metastasis was reduced in size and the tumor marker levels were decreased, so subtotal stomach-preserving pancreaticoduodenectomy was performed. Adjuvant chemotherapy was administered postoperatively. The patient was alive and well without recurrence 2 years and 9 months after the surgery, but died of sepsis. Nevertheless, this case highlights that when preoperative chemotherapy for resectable pancreatic cancer appears to be ineffective, a change in regimen may be useful.

The patient is a 74-year-old woman. She had breast cancer(invasive ductal carcinoma, ER[+], PgR[+], HER2[-], Ki-67: 30-40%)and primary right lung cancer with lumbar metastasis, which led to the diagnosis synchronous double cancers of the breast and the lung. We decided to precede surgery for lung cancer because breast cancer was indicated hormonal receptor positive. Breast cancer is treated with anastrozole, thoracoscopic right upper lobectomy was performed for the lung cancer. Radiation therapy was performed for metastatic bone tumors. 13 months later, partial mastectomy sentinel lymph node biopsy performed. The histopathological diagnosis of breast cancer was pT2, pN0, cM0, pStage ⅡA, and histological response was Grade 2a. The remaining breast was treated radiation therapy. The breast cancer has not recurred and is doing well 6 months after surgery. As for primary lung cancer, 19 months have passed since surgery, and the patient is in complete remission without recurrence.

A 31-year-old man with a big epigastric mass from pancreas body was completely removed by distal pancreatectomy and segmental gastrectomy. Two years after oral administration of S-1 for 4 courses, peritoneal dissemination on the right subdiaphragmatic space was detected. Laparotomy revealed white colored round nodules were found scattered on the peritoneal surface, and the peritoneal cancer index(PCI)was 18. To achieve complete resection of peritoneal nodules, peritonectomy was performed. After complete removal of macroscopic peritoneal metastasis(PM), intraoperative hyperthermic intraoperative peritoneal chemotherapy using 1 gr of gemcitabine and 60 mg of docetaxel was performed for 40 min with thermal dose of 41.5 min. Postoperative course was uneventful. Drug sensitivity test(HDRA method)showed that gemcitabine that gemcitabine showed the highest inhibition rate. The patient was treated with systemic gemcitabine chemotherapy. He is still alive without recurrence 18 months after peritonectomy plus intraoperative HIPEC. Pathological examination showed pancreatic acinar cell carcinoma(PACC)demonstrating positive for chymotrypsin. In conclusion, we present a PACC-case with PM successfully treated by a comprehensive treatment. Intraoperative HIPEC using gemcitabine may be effective for PACC patients with PM in treating residual micrometastasis after peritonectomy.

The case is a woman in her 60s. Sigmoid colon cancer surgery, liver metastasis surgery, and adjuvant chemotherapy were performed at another hospital 2 years ago. Later, she developed a metastasis in her liver and was recommended surgery, but she refused treatment and was transferred. Her liver metastasis had invaded the stomach and formed a giant gastric ulcer. This time she had an adhesive ileus and underwent laparoscopic surgery at our hospital. At that time, we observed the state of liver metastasis and gastric infiltration by laparoscopy, so we thought that palliative surgery was possible and recommended it. Although she initially refused treatment, the relative ease with which her ileus surgery was performed encouraged her to undergo palliative surgery. Laparoscopic-assisted gastrectomy and partial hepatectomy were performed, and she was discharged on hospital day 13 after surgery. She subsequently developed liver metastases and died 8 months after palliative surgery, although she was able to eat and maintain her ADL until the end of life. By staying close to the patient, we were able to lead the patient from refusal of surgery to palliative surgery, and we felt that we were able to make the patient reach a favorable end.

Some cases of advanced hepatocellular carcinoma(HCC)diagnosed as unresectable(UR)have been reported to undergo conversion surgery following systemic therapy. Furthermore, the combination of atezolizumab plus bevacizumab(Atez/Bev) shows potential therapeutic effects in conversion surgery for UR-HCC. At our hospital, neoadjuvant chemotherapy(NAC) using New-FP therapy(hepatic arterial infusion chemotherapy: HAIC)has been performed for borderline resectable HCC. New-FP therapy for advanced HCC with macrovascular invasion has a high response rate of 70%. For hepatectomy after NAC, a high response rate is required as a pretreatment, and New-FP therapy may be useful as the initial treatment. Limited reports exist of the laparoscopic approach in conversion surgery for advanced HCC. However, 14 cases of minimally invasive liver resection, including 10 cases after New-FP therapy and 4 cases after Atez/Bev therapy, have been safely performed conversion surgery for advanced HCC. In selected patients with advanced HCC, minimally invasive liver resection may be safely performed if the tumor shows shrinkage with various treatments.

We investigated the safety and efficacy of UDON(5-FU, docetaxel and nedaplatin), a similar DCF therapy, as neoadjuvant chemotherapy for advanced esophageal cancer. Twelve patients who underwent radical esophagectomy after neoadjuvant chemotherapy for esophageal cancer at our department from June 2021 to December 2022 were retrospectively evaluated. One patient had Grade Ⅲ or higher neutropenia(8%)and 2 patients had anorexia(15%)as adverse events, but they could be safely treated. Nutritional status and ADL were maintained in all patients, and surgery was performed after 2-3 courses of neoadjuvant chemotherapy. The median postoperative hospital stay was 14 days, and no severe postoperative complications were observed. The histological effect to chemotherapy was Grade 3 in 3 patients(23%). UDON therapy is a safe and effective treatment.

A 58-year-old woman presented with a complaint of weight loss. Abdominal computed tomography showed dilatation of the biliary and pancreatic ducts and a mural nodule in the pancreatic duct. The diagnosis was intraductal papillary mucinous neoplasm(IPMN). Endoscopic retrograde cholangiopancreatography(ERCP)and cholangioscopy revealed a fistula between the common bile duct and the IPMN. A sudden increase in hepatobiliary enzymes was noted preoperatively. ERCP showed that the common bile duct was obstructed by mucus. A nasobiliary drainage tube was inserted into the bile duct endoscopically and kept open by daily tube washing, and the liver dysfunction improved. Total pancreatectomy, splenectomy, and regional lymph node dissection were performed. Histological examination confirmed that the primary tumor was mixed invasive intraductal papillary mucinous adenocarcinoma. The patient remains alive and well with no evidence of recurrence 18 months after resection.

A 66-year-old man was referred to our hospital with fever and abdominal pain. CT showed a mass in the intrapancreatic bile duct but no wall thickness in the perihilar bile ducts. Neither regional lymphadenopathy nor distant metastasis was observed. Biliary cytology showed adenocarcinoma. The diagnosis was distal cholangiocarcinoma, and pancreatoduodenectomy was performed. Intraoperative frozen section examination of the ductal resection margins at the right and left hepatic ducts was positive for carcinoma in situ, and the operation ultimately completed with R1 resection. Histological examination confirmed a diagnosis of cholangiocarcinoma with superficial spread and a single positive lymph node. Adjuvant chemotherapy with S-1 was administered for 1 year. Anastomotic recurrence at the hepaticojejunostomy was found 5 years after resection; biopsy specimens revealed adenocarcinoma. Thereafter, S-1 chemotherapy was resumed, and the patient remains alive and well 9 years and 1 month after resection.

As medical insurance coverage for robotic surgery has been expanded in the field of gastrointestinal surgery in Japan, the number of cases undergoing robotic surgery for hepato-biliary-pancreatic disease has been increasing. Therefore, cases with malignant tumors and metastatic lesions tend to undergo robotic operation for both primary tumors and metastases. Herein, we report a case of neuroendocrine tumor(NET)in the pancreatic tail with simultaneous single liver metastasis, which was treated with two-stage robotic-assisted surgery. A 67-year-old female underwent a computed tomography scan and a hypovascularized tumor in the pancreatic tail region and liver was found. A biopsy of the pancreatic tumor by endoscopic ultrasound-guided fine needle aspiration demonstrated a NET G1-2. The liver lesion was diagnosed as a metastatic tumor, considering the other examinations. The patient underwent a robotic distal pancreatectomy(RDP)and was histopathologically diagnosed as NET G2. Sixty-three days after the RDP, a two-stage partial liver resection for the metastatic tumor was performed under robotic assistance. Curative resection was achieved through two-stage robot-assisted surgery, there were no postoperative complications.

A 72-year-old man visited his local doctor for gastric discomfort. Esophagogastroduodenoscopy revealed a type 3 tumor on the gastric antrum, and histopathological examination revealed a moderately differentiated adenocarcinoma(tub2). The patient was referred to our hospital and CT scan revealed wall thickening with contrast effect in the gastric angle but no enlarged lymph nodes in the region. The patient was diagnosed as cT3N0M0, Stage ⅡB gastric cancer and underwent open distal gastrectomy and D2 lymph node dissection. No peritoneal dissemination was observed, but intraoperative laparoscopic cytology showed Class Ⅴ. The patient was diagnosed as CY1 Stage Ⅳ gastric cancer, and treated with S-1 plus Tmab therapy starting 1 month after surgery. One year postoperative follow-up CT revealed recurrence of peritoneal disseminations, and the patient was treated with nab-PTX as a second-line therapy. Tumor shrinkage was achieved steadily, and the peritoneal disseminations disappeared at the CT after 12 courses, resulting in cCR. Thereafter, cCR continued and treatment was terminated at the 17th course. Seven years have passed since the end of chemotherapy, and the patient is still alive without recurrence.

A 56-year-old female was referred to our hospital for further examination and treatment because of her increasing right axillary mass for 1 year. Based on histological examination diagnosing the right axillary mass as carcinoma and radiological examination showing no evidence of distal metastasis, we decided to perform a radical resection. The patient underwent right axillary mass resection, axillary lymph node dissection, and latissimus dorsi musculocutaneous flap reconstruction. Right-sided breast cancer was diagnosed based on histopathological examination. The diagnosis was similar to that of breast cancer. The patient underwent adjunctive chemotherapy and is currently undergoing endocrine therapy. The incidence of accessory breast cancer is 0.2-0.6% among all breast cancers and is relatively rare. Postoperative adjuvant pharmacotherapy has no consensus. However, endocrine therapy, chemotherapy, and molecular target therapy are performed in cases of conventional breast cancer. Herein, we describe a case of right axillary accessory breast cancer with skin invasion successfully treated with radical resection.
