RESUMO
BACKGROUND: Prehabilitation during neoadjuvant therapy has the potential to improve clinical outcomes. However, information on its global dissemination status is limited. This Japanese nationwide survey investigated the implementation status of and barriers to prehabilitation during neoadjuvant chemotherapy (NAC) for patients with locally advanced esophageal cancer in hospitals. METHODS: This multicenter nationwide survey was conducted by post. The eligible facilities were 155 Japanese hospitals that had been certified within the last 10 years as authorized institutes for board-certified esophageal surgeons by the Japan Esophageal Society. We administered an original questionnaire to investigate the current status of prehabilitation during NAC. RESULTS: The response rate was 75% (117/155 facilities). Forty-six facilities (39%) provided prehabilitation during NAC. The most frequently selected reasons for not providing or providing insufficient prehabilitation were lack of human resources, issues with the reimbursement of medical fees, difficulty in providing continuous prehabilitation during repeated inpatient and outpatient care, the lack of established standard prehabilitation programs, challenges in providing multidisciplinary prehabilitation, and difficulty in managing physical symptoms. CONCLUSION: We observed that the implementation rate of prehabilitation during NAC was low. Critical reasons were not only the lack of medical resources but also the lack of evidence-based standard prehabilitation programs during NAC and the lack of evidence for how to continuously deliver prehabilitation during NAC to patients with physical symptoms.
RESUMO
Sarcopenia is prevalent among 11-25% of adult cancer survivors, depending on the cancer type, although the available data on post-treatment survivors in Japan are limited. If cancer patients develop cachexia, they may experience sustained weight loss as a result, ultimately leading to sarcopenia. Conversely, some patients experience post-treatment weight gain, resulting in sarcopenic obesity. Both sarcopenia and obesity elevate the risk of cardiovascular diseases and mortality; therefore, the importance of sarcopenia prevention and management is undeniable. The Guidelines for Exercise for Cancer Survivors recommend continued physical activity. Recent studies have reported the effectiveness of multimodal interventions, combining pharmacological, nutritional, and exercise approaches, necessitating multidisciplinary care for post-treatment sarcopenia. Innovative health interventions using mobile devices have also gained attention. However, studies on sarcopenia in post-treatment cancer survivors, especially those regarding exercise interventions, remain scarce in Japan, primarily due to limited insurance coverage for such post-treatment interventions and workforce challenges. It is clear that some cancer survivors have sarcopenia, which can lead to worse survival and secondary illness. While the benefits of exercise are clear, a comprehensive approach to sarcopenia is a further challenge for the future.

This systematic review and meta-analysis investigated the impact of quality of life (QoL) on mortality risk in patients with esophageal cancer. A literature search was conducted using the CINAHL, PubMed/MEDLINE, and Scopus databases for articles published from inception to December 2022. Observational studies that examined the association between QoL and mortality risk in patients with esophageal cancer were included. Subgroup analyses were performed for time points of QoL assessment and for types of treatment. Seven studies were included in the final analysis. Overall, global QoL was significantly associated with mortality risk (hazard ratio 1.02, 95% confidence interval 1.01-1.04; p < 0.00004). Among the QoL subscales of QoL, physical, emotional, role, cognitive, and social QoL were significantly associated with mortality risk. A subgroup analysis by timepoints of QoL assessment demonstrated that pre- and posttreatment global and physical, pretreatment role, and posttreatment cognitive QoL were significantly associated with mortality risk. Moreover, another subgroup analysis by types of treatment demonstrated that the role QoL in patients with surgery, and the global, physical, role, and social QoL in those with other treatments were significantly associated with mortality risk. These findings indicate that the assessment of QoL in patients with esophageal cancer before and after treatment not only provides information on patients' condition at the time of treatment but may also serve as an outcome for predicting life expectancy. Therefore, it is important to conduct regular QoL assessments and take a proactive approach to improve QoL based on the results of these assessments.

PURPOSE: This systematic review and meta-analysis aimed to examine the impact of global quality of life (QOL) on mortality risk in patients with cancer, considering cancer type and timepoint of QOL assessment. METHODS: A systematic search was conducted using Cumulated Index to Nursing and Allied Health Literature, PubMed/MEDLINE, and Scopus databases from inception to December 2022. Observational studies that assessed QOL and examined mortality risk in patients with cancer were extracted. Subgroup analyses were performed for cancer types and timepoints of QOL assessment. RESULTS: Overall, global QOL was significantly associated with mortality risk (hazard ratio: 1.06, 95% confidence interval: 1.05-1.07; p < 0.00001). A subgroup analysis based on cancer type demonstrated that lung, head and neck, breast, esophagus, colon, prostate, hematologic, liver, gynecologic, stomach, brain, bladder, bone and soft tissue, and mixed type cancers were significantly associated with mortality risk; however, melanoma and pancreatic cancer were not significantly associated with mortality risk. Additionally, global QOL was associated with mortality risk at all timepoints (pretreatment, posttreatment, and palliative phase); pretreatment QOL had the largest impact, followed by posttreatment QOL. CONCLUSION: These findings provide evidence that QOL is associated with mortality risk in patients with cancer at any timepoint. These results indicate the importance of evaluating the QOL and supportive interventions to improve QOL in any phase.
RESUMO
BACKGROUND: Patients with breast cancer present with various problems that have an adverse effect on the quality of life (QOL). However, the association between the QOL and mortality among patients with breast cancer remains controversial. Therefore, this systematic review and meta-analysis aimed to determine whether QOL impacts prognosis in patients with breast cancer. METHODS: The databases of CINAHL, Scopus, and PubMed databases were searched to retrieve observational studies that assessed the QOL and mortality risk in patients with breast cancer published before December 2022. RESULTS: Among the 119,061 articles retrieved, six observational studies were included in the meta-analysis. Physical QOL (hazard ratio [HR]: 1.04, 95% confidence interval [CI]: 1.01-1.07, p = 0.003), emotional QOL (HR: 1.01, 95% CI: 1.00-1.03, p = 0.05), and role QOL (HR: 1.01, 95% CI: 1.00-1.01, p = 0.007) showed significant associations with mortality risk. In contrast, global QOL, cognitive QOL, and social QOL showed no associations with mortality risk. Subgroup analysis performed according to treatment time points revealed that the post-treatment physical QOL was associated with mortality risk. CONCLUSIONS: Physical QOL, emotional QOL, and role QOL are associated with mortality risk in patients with breast cancer. Furthermore, post-treatment physical QOL showed a more significant association with prolonged survival than pre-treatment physical QOL.

BACKGROUND: Although many studies have explored the correlation between quality of life and survival, none have reported this relationship for specific cancers assessed at distinct time points. This meta-analysis aimed to investigate the impact of pretreatment Global Quality of Life (QOL) and functioning QOL, including physical, social, role, emotional, and cognitive QOLs, on mortality risk in patients with lung cancer. METHODS: A literature search was conducted across the Cumulative Index to Nursing and Allied Health Literature (CINAHL), Scopus, and PubMed databases for articles published between their inception and December 2022. Subsequently, 11 studies were selected based on predefined eligibility criteria to investigate the relationship between pretreatment QOLs and mortality risk in patients with lung cancer. RESULTS: Pretreatment global, physical, social, role, and emotional QOLs were significantly associated with mortality risk as follows: Global QOL (hazard ratio [HR] = 1.08 95% confidence interval [CI] = 1.03-1.13); Physical QOL (HR = 1.04 95% CI = 1.02-1.05); Social QOL (HR = 1.02 95% CI = 1.01-1.03; Role QOL (HR = 1.01 95% CI = 1.01-1.02); Emotional QOL (HR = 1.01 95% CI = 1.00-1.03). CONCLUSIONS: These findings underscore the importance of early QOL assessment after diagnosis as well as early provision of physical, social, and psychological support accommodating each patient's demands.

BACKGROUND: This systematic review and meta-analysis aimed to determine whether chemotherapy-induced peripheral neuropathy (CIPN) affects the risk of falls and physical function in patients with cancer. METHODS: A literature search was conducted in the CINAHL, Scopus, and PubMed databases for articles published from January 1950 to April 2022. Seven review authors retrieved studies using predetermined eligibility criteria, extracted the data, and evaluated the quality. RESULTS: Nine studies were included in the analysis. Patients with CIPN had a significantly higher risk of falls than those without CIPN (risk ratio = 1.38, 95% confidence interval [CI] =1.18-1.62). Patients with CIPN had lower grip strength (standardized mean difference [SMD] =-0.42, 95% CIs = -0.70 to -0.14, P = .003), longer chair stand time (SMD = 0.56, 95% CIs = -0.01 to 1.17, P = .05), worse timed up and go test time (SMD = 0.79, 95% CIs = 0.41 to 1.17, P < .0001), and lower mean Fullerton Advanced Balance scale score (SMD = -0.81, 95% CIs = -1.27 to -0.36, P = .005) than patients without CIPN. There were no significant differences in gait speed (P = .38) or Activities-specific Balance Confidence Scale score (P = .09) between patients with and without CIPN. CONCLUSIONS: This systematic review and meta-analysis demonstrated that patients with CIPN are prone to falls and impaired balance function and muscle strength.

In recent years, the number of cancer survivors has been increasing each year due to advances in the early diagnosis and treatment of cancer. Cancer survivors present a variety of physical and psychological complications due to cancer and its treatment. Physical exercise is an effective nonpharmacological treatment for complications in cancer survivors. Furthermore, recent evidence has shown that physical exercise improves the prognosis of cancer survivors. The benefits of physical exercise have been widely reported, and guidelines for physical exercise for cancer survivors have been published. These guidelines recommend that cancer survivors engage in moderate- or vigorous-intensity aerobic exercises and/or resistance training. However, many cancer survivors have a poor commitment to physical exercise. In the future, it is necessary to promote physical exercise among cancer survivors through outpatient rehabilitation and community support.
RESUMO
BACKGROUND/AIM: To investigate the effects of ocular and systemic risk factors for glaucomatous progression in different sectors of the visual field (VF). METHOD: 409 eyes from 268 patients with 10 reliable VFs from the Japanese Archive of Multicentral Databases in Glaucoma (JAMDIG) were investigated. VFs were divided into six sectors (mean total deviation (mTD)s20+, mTDs10-20 and mTDs0-10, >20°, 10-20° and <10° in the superior hemifield, respectively; and mTDi20+, mTDi10-20 and mTDi0-10, >20°, 10-20° and <10° in the inferior hemifield, respectively). The relationship between sectorial progression rate and eight variables (age, mTD at baseline VF, average intraocular pressure (IOP), SD of IOP, systemic hypertension, migraine, family history of glaucoma and smoking status) was investigated. RESULT: The mTD progression rate was -0.21â dB/year. Older age was related to progression of mTDs20+, mTDs10-20, mTDi20+ and mTDi10-20. Mean IOP was not related to progression in any VF sector; however, a larger SD of IOP was related to progression of mTDs20+, mTDi0-10, mTDi10-20 and mTDi20+. Smoking status was related to progression in all inferior VF sectors (mTDi0-10, mTDi10-20 and mTDi20+). CONCLUSIONS: Smoking status is related to glaucomatous VF progression in all sectors of the inferior hemifield.

We report herein on a case of ectopic cervical thymus in a 5-year-old boy and the literature is reviewed. Swelling of the right neck was seen in the patient in his newborn period and it was diagnosed as cystic disease of the neck in a previous hospital at 4 months of age. Ultrasonography (US) and MRI revealed a cervical tumor consisting of a solid component in our hospital, and histopathologic examination showed no evidence of malignancy. The lesion revealed almost no change in size but showed a mosaic pattern on US, whereon the parents agreed to the removal of the tumor. Intraoperatively, the tumor could be easily dissected from the surrounding tissue and resected. The pathological diagnosis was normal thymic tissue. The postoperative course was uneventful and no complication or immunological disorders were seen. A cervical ectopic thymus is a congenital lesion that results from abnormal thymic migration during embryogenesis. Most patients are asymptomatic and the condition is found incidentally. Preoperative diagnosis of cervical ectopic thymus in children is rarely made, so surgical treatment is the definitive means of pathological diagnosis. This disease should be listed in the differential diagnosis for neck masses in children, and should be suspected when the mosaic pattern is detected in the lesion on US.

PURPOSE: Scar formation is most frequently responsible for the failure of glaucoma filtration surgery. Retinoic acids are vitamin A derivatives that play diverse roles in development, immunity, and tissue repair. The effects of the retinoic acid receptor (RAR) γ agonist R667 on the contractility of human Tenon fibroblasts (HTFs) cultured in a three-dimensional collagen gel as well as on intraocular pressure (IOP) in a rat model of glaucoma filtration surgery were investigated. METHODS: HTFs were cultured in a type I collagen gel, the contraction of which was evaluated by measurement of the gel diameter. The release of matrix metalloproteinases (MMPs) into culture supernatants was assessed with immunoblot analysis and gelatin zymography. Phosphorylation of focal adhesion kinase (FAK) was examined with immunoblot analysis, and production of fibronectin and type I collagen was measured with immunoassays. RESULTS: R667 inhibited transforming growth factor-ß1 (TGF-ß1)-induced collagen gel contraction mediated by HTFs in a concentration- and time-dependent manner, whereas an RARα agonist inhibited this process to a lesser extent and an RARß agonist had no effect. TGF-ß1-induced MMP-1 and MMP-3 release, FAK phosphorylation, and fibronectin and type I collagen production in HTFs were also attenuated by R667. Furthermore, R667 lowered IOP in rats after glaucoma filtration surgery. CONCLUSIONS: R667 inhibited TGF-ß1-induced contraction and extracellular matrix synthesis in HTFs. Such effects might have contributed to the lowering of IOP by R667 in a rat model of glaucoma filtration surgery. RARγ agonists might thus prove effective for inhibition of scar formation after such surgery.

PURPOSE: Collagen contraction mediated by retinal pigment epithelial (RPE) cells contributes to the pathogenesis of proliferative vitreoretinopathy (PVR). We examined the effects of sex hormones on this process. METHODS: Mouse RPE cells were cultured in a type I collagen gel and exposed to 17ß-estradiol, progesterone, or dehydro-epiandrosterone. Collagen contraction induced by transforming growth factor-ß2 (TGF-ß2) was determined by measurement of gel diameter. Expression of α-smooth muscle actin (α-SMA), as well as phosphorylation of Smad2 and myosin light chain (MLC), was examined by immunoblot analysis. Matrix metalloproteinase (MMP) release was evaluated by gelatin zymography. Fibronectin and interleukin-6 secretion was measured with immunoassays. RESULTS: The female sex hormones 17ß-estradiol and progesterone inhibited TGF-ß2-induced collagen contraction mediated by RPE cells, whereas the male sex hormone dehydro-epiandrosterone had no such effect. The TGF-ß2-induced release of MMP-2 and MMP-9 from RPE cells was also inhibited by 17ß-estradiol and progesterone, and the MMP inhibitor GM6001 attenuated TGF-ß2-induced collagen contraction. Expression of the mesenchymal markers α-SMA and fibronectin, interleukin-6 release, and Smad2 and MLC phosphorylation induced by TGF-ß2 were all inhibited by 17ß-estradiol and progesterone. Immunohistochemical analysis also detected nuclear immunoreactivity for estrogen and progesterone receptors in proliferative fibrocellular membranes of PVR patients. CONCLUSIONS: Female sex hormones inhibited TGF-ß2-induced collagen contraction mediated by RPE cells. This action appeared to be mediated through inhibition both of MMP, α-SMA, and fibronectin expression as well as of Smad2 and MLC phosphorylation. Female sex hormones might thus prove effective for the treatment of PVR.

PURPOSE: Keratocytes are connected to each other by gap junctions, which mediate intercellular communication and contribute to maintenance of corneal homeostasis. The possible effect of tumor necrosis factor (TNF)-alpha, a proinflammatory cytokine, on gap junctional intercellular communication (GJIC) in cultured human corneal fibroblasts was examined. METHODS: GJIC activity was measured by observing the intercellular diffusion of the fluorescent dye Lucifer yellow. The expression of the gap junction protein connexin43 (Cx43) was evaluated by immunofluorescence and immunoblot analyses with a specific monoclonal antibody. The abundance of Cx43 mRNA was determined by quantitative reverse transcription and polymerase chain reaction analysis. RESULTS: TNF-alpha induced a time- and concentration-dependent decrease in GJIC activity in human corneal fibroblasts. Immunofluorescence analysis revealed that TNF-alpha reduced the level of specific staining for Cx43 at sites of contact between adjacent cells. Immunoblot analysis detected four specific Cx43 bands, one corresponding to the nonphosphorylated form of the protein and three corresponding to phosphorylated forms. Exposure of cells to TNF-alpha reduced the relative abundance of the three phosphorylated forms of Cx43. The amount of Cx43 mRNA was not affected by TNF-alpha. CONCLUSIONS: TNF-alpha inhibited GJIC in cultured human corneal fibroblasts, an effect that was possibly mediated by dephosphorylation and consequent degradation of Cx43. The downregulation of GJIC among keratocytes in response to TNF-alpha may contribute to the breakdown of corneal homeostasis during corneal inflammation.
