文摘Caregiver load refers to the subjective and objective negative impact of caregivers in the care of patients,and excessive load will have a serious impact on patients and caregivers themselves and can reduce their quality of life.For the main caregivers,it not only needs to care for the patients in life and daily life,but also needs to pay the cost of treatment for the patients,coupled with the need to carry out their own original work,life,etc.excessive life pressure,economic pressure,work pressure,emotional pressure,etc.lead to heavy load of the main caregivers,which can easily cause caregivers to have different degrees of psychological problems,which will cause serious adverse effects on the caregivers themselves and cancer patients,not conducive to the construction of a harmonious family and society.This article analyzes the current situation of primary caregiver burden in patients with gastrointestinal malignant tumors,analyzes its influencing factors,and specifies specific treatment strategies.It is hoped to provide scientific guidance for later related research and application.
文摘BACKGROUND Few relevant literature reports on applying acupoint press-needle embedding combined with emotional nursing in patients with a gynecological malignant tumor.AIM To explore the effect of traditional Chinese medicine acupoint needle embedding combined with emotional nursing on chemotherapy-related nausea and vomiting(CINV),cancer-related fatigue(CRF)and psychological state in patients with gynecological malignant tumors.METHODS Retrospective analysis of the clinical information of 84 patients with gynecological malignant tumors treated in our hospital from August 2020 to December 2022 Led to the development of an observation group(n=42)and a control group(n=42)based on various nursing approaches.Ondansetron hydrochloride injection was administered to the individuals in the control group.However,the observation group received emotional nursing based on the control group and acupoint pressneedle embedding of traditional Chinese medicine.Patients in both groups received the chemotherapy regimen of paclitaxel liposome+carbo-platin/cisplatin.For four weeks,both groups intervened.The CINV grade,quality of life,CRF,psychological status and sleep quality scores of the two groups before and RESULTS After intervention,the degree of CINV in the observation group was significantly better than that in the control group.After intervention,the scores of each dimension and total score of FLIE scale were significantly higher than those in the control group.After intervention,the scores of each dimension and total score of Piper Fatigue Scale were significantly lower than those in the control group(P<0.05).After intervention,the scores of avoidance and yield dimensions in the observation group were significantly lower than those in the control group,and the scores of confrontation dimension were significantly higher than those in the control group(P<0.05).After intervention,the sleep quality score of the observation group was significantly lower than that of the control group,and the Karnofsky Performance Status scale score was significantly higher than that of the control group(P<0.05).CONCLUSION The acupuncture point needle embedding of traditional Chinese medicine combined with emotional nursing can further reduce the incidence of chemotherapy-related nausea and vomiting in patients with gynecological malignant tumors,improve the quality of life and the degree of CRF,alleviate the bad psychological state,adopt a positive way to face the disease and treatment,and improve the quality of sleep and quality of life.
文摘BACKGROUND Malignant peripheral nerve sheath tumor(MPNST)is a rare and aggressive soft tissue sarcoma that poses a major diagnostic and therapeutic challenge.CASE SUMMARY We retrospectively reviewed patients with head and neck MPNSTs treated in our hospital from 2000 to 2021.The clinical features,pathological manifestations,treatments,and prognoses were summarized.We also reviewed the literature,focusing on MPNST in the mandible and maxilla.The study population consisted of five women and five men aged 22–75 years(mean age,49 years).Of the 10 patients,7 were initial cases and 3 were recurrent cases.All lesions were sporadic.The most common site was the mandible.The most frequently encountered symptoms were a progressive mass and local swelling.Complete or partial loss of trimethylation at lysine 27 of histone H3(H3K27me3)was evident on staining in four of nine cases(one case was excluded due to lack of tissue for evaluation of loss of H3K27me3).The 2-and 5-year disease-specific survival rates were 86%a nd 43%,respectively.The average survival time was 64 mo.CONCLUSION MPNST is a highly malignant tumor with a poor prognosis,prone to a high risk of recurrence and distant metastasis.Complete surgical resection is the main treatment.
文摘BACKGROUND Malignant schwannoma is a rare tumor in the peripheral nervous system,accounting for approximately 5%to 10%of systemic soft tissue sarcomas.Especially,malignant schwannoma occurring in the broad ligament of the uterus with hemophilic syndrome and bone marrow fibrosis is extremely rare in clinical practice.Here,we report the first case of an patient diagnosed with malignant peripheral nerve sheath tumor(MPNST)of the broad ligament of the uterus with hemophilic syndrome and bone marrow fibrosis,and share our reference clinical diagnosis and treatment experience.CASE SUMMARY A patient was diagnosed with MPNST of the uterus harboring hemophilic syndrome and bone marrow fibrosis.She received combination,and repeated imaging revealed further encountered rare complications(hemophilia syndrome and bone marrow fibrosis)after two cycles of chemotherapy.Thereafter,combined treatment with pazopanib,gemcitabine,and dacarbazine was initiated.Unfortunately,the patient succumbed to death at hospital after two weeks.CONCLUSION This report firstly provided reference clinical practice for a patient with MPNST of the uterus harboring hemophilic syndrome and bone marrow fibrosis.Our case raises a reminder about the tolerance and safety of combination therapy,especially in young women.
文摘BACKGROUND Malignant small round cell tumor(MSRCT)metastasis to the common bile duct associated with recurrent biliary hemorrhage is extremely rare.Thus far,there have been no reports of metastatic small round cell tumors of the common bile duct.CASE SUMMARY Herein,we report the case of a 77-year-old female patient with an MSRCT in the common bile duct.The patient was admitted to hospital due to gastrointestinal hemorrhage and abdominal pain.We found a neoplasm in the common bile duct with active bleeding through a spyglass.We performed biopsy through the spyglass and placed a metal stent to stop bleeding.The pathological result suggested that it was an MSRCT metastasized from the back to the common bile duct.Later,we found using fluorescence in situ hybridization that the SS18 gene break test was negative,ruling out the diagnosis of synovial sarcoma.CONCLUSION MSRCT is a group of tumors with similar cell morphology and diffuse histological structure.Complete tumor resection results in improved survival in patients with MSRCT.Roux-en-Y cholangiojejunostomy was performed.After excision of the common bile duct tumor,the patient felt that the abdominal pain improved and hemorrhage disappeared.The patient underwent routine fecal examination one month after surgery,indicating a negative fecal occult blood test.On May 22,2023,the patient was reexamined by abdominal computed tomography,and no abdominal space occupying lesions or abdominal lymphadenopathy was found.
文摘Objective:To explore and analyze the evaluation and driving factors of postoperative psychological pain inpatients with oral and maxillofacial malignant tumors.Methods:Relevant data were collected from 80 patients with oral and maxillofacial malignant tumors who attended the outpatient clinic for follow-up consultations between May 2021 to May 2023.The patients used the psychological distress thermometer(DT)to circle words that best described their experiences in the past week,assigning a numerical value(0-10)to indicate their pain level on each day.The scoring results were employed to assess the psychological pain in these patients.A self-developed patient basic information questionnaire was utilized to record demographic details.Logistic regression analysis was employed to evaluate patients two weeks after surgery,focusing on the assessment of psychological distress and the identification and location of driving factors.Results:Following evaluation,the results revealed that the average postoperative DT score for the 80 patients with oral and maxillofacial malignant tumors was 4.53±1.98 points.Scores<4 points indicated no psychological pain(Group N)in 48 cases,while scores≥4 points indicated psychological pain(Group Y)in 32 cases.The differences in postoperative DT scores among patients with varying educational levels,fears and worries about disease progression,economic problems,sleep problems,level of hope,and oral pain were statistically significant(P<0.05).Multiple linear regression analysis results indicated that education level,fear and worry about disease progression,economic problems,sleep problems,level of hope,and oral pain are driving factors of postoperative psychological pain in patients with oral and maxillofacial malignant tumors(P<0.05).Conclusion:The postoperative psychological pain level in patients with oral and maxillofacial malignant tumors is at a moderate level.Educational level,fear and worry about disease progression,economic problems,sleep problems,level of hope,and oral pain were identified as driving factors for postoperative psychological pain in these patients.
文摘BACKGROUND Extragastrointestinal stromal tumors(EGIST)and gastrointestinal stromal tumors are of similar pathological type and form.Here we report a rare case of EGIST diffusely distributed in membranous tissue in abdominal cavity,the feature of which included diffuse tumors at membranous tissue in entire abdominal cavity and spontaneous bleeding of the tumors.CASE SUMMARY The patient was a 71-year man and hospitalized due to continuous pain at lower abdomen for more than 10 days.Upon physical examination,the patient had flat and tough abdomen with mild pressing pain at lower abdomen,no obvious abdominal mass was touchable,and shifting dullness was positive.Positron emission tomography-computed tomography(CT)showed that in his peritoneal cavity,there were multiple nodules of various sizes,seroperitoneum,multiple enlarged lymph nodes in abdominal/pelvic cavity and right external ilium as well as pulmonary nodules.Plain CT scanning at epigastrium/hypogastrium/pelvic cavity+enhanced three-dimensional reconstruction revealed multiple soft tissue nodules in abdominal/pelvic cavity,peritoneum and right groin.Tumor marker of carbohydrate antigen 125 was 808 U/mL,diffuse tuberous tumor was seen in abdominal/pelvic cavity during operation with hematocelia,and postoperative pathological examination confirmed EGIST.Imatinib was administered with better therapeutic effect.CONCLUSION Gene testing showed breast cancer susceptibility gene 1 interacting protein C-terminal helicase 1 and KIT genovariation,and the patient was treated with imatinib follow-up visit found that his clinical symptoms disappeared and the tumor load alleviated obviously via imageological examination.
