RESUMO
Objective:To investigate the feasibility and adverse reactions of simultaneous integrated boost (SIB) in volumetric modulated arc therapy (VMAT) for early breast cancer after breast-conserving surgery.Methods:A total of 67 patients with early breast cancer after breast-conserving surgery at Zhongshan People's Hospital from September 2019 to May 2021 were enrolled. All patients received VMAT-SIB to the whole breast and tumor bed. The total breast dose and tumor bed dose were 40.5Gy/15 times every 3 weeks and 48 Gy/15 every 3 weeks respectively. The exposure dose of organs at risk and acute adverse reactions of radiotherapy were evaluated.Results:The average doses of planning target volume of the whole brease (PTV WB) and planning target volume of the boost(PTV BOOST) were (42.0±2.1) Gy and (49.9±0.8) Gy, respectively. The V 95% and V 105% of PTV WB and PTV BOOST were (98.8±1.2)% and (31.4±11.3)%, (99.8±0.6)% and (22.9±10.2)%, respectively. The V 5Gy, V 20Gy, V 30Gy and mean dose (D mean) of ipsilateral lung were (52.4±12.0)%, (15.3±4.5)%, (6.7±2.2)% and (11.0±2.4) Gy respectively. The V 18Gy, V 40Gy and D mean of heart were 3.80% (0.48%,9.60%), 0 (0,0.16%) and (6.7±2.1) Gy respectively. At the end of radiotherapy, 19 patients (29%) of all 67 patients had no acute skin toxicity, 41 patients (61%) showed radiation erythema, 5 patients (7%) had radioactive dry peeling and 2 patients (3%) had wet peeling mainly located in the nipple, areola area and breast folds. None of the patients had grade 3-4 acute skin reactions. Breast swelling and breast pain were found respectively in 9 patients (13%) and 7 patients (10%). No local recurrence or distant metastases were observed during the follow-up period. The 2-year disease-free survival rate was 100%. Conclusions:VMAT combined with SIB is feasible in the treatment of early breast cancer. The adverse reactions of radiotherapy are mild and well tolerated.
RESUMO
ObjectiveTo explore the effect of home visit based on empowerment education on psychotic symptoms， self-management ability and well-being of schizophrenia patients in home rehabilitation. MethodsA total of 87 cases of schizophrenia patients who met the diagnostic criteria of International Classification of Diseases， tenth edition （ICD-10） and were recovering at home in Caiba town， Yibin city from January to July 2021 were selected by random sampling method as research subjects. They were divided into experimental group （n=43） and control group （n=44） according to the random number table method. The two groups received routine family visits， and the experimental group received family visits based on empowerment education. The intervention cycle of the two groups was 6 months. Before and after the intervention， the severity of psychotic symptoms， self-management ability and well-being of the patients in the two groups were assessed with the Brief Psychiatric Rating Scale （BPRS）， the Schizophrenia Self-Management Instrument Scale （SSMIS） and the Index of Well-Being Scale （IWB）. ResultsAfter intervention， the intra group comparison showed that the BPRS score in the experimental group was lower than that before the intervention （t=4.550， P<0.01）， the SSMIS scores in both groups were higher than those before intervention （t=-17.107， -6.367， P<0.01）， and the IWB score in the experimental group was higher than that before intervention （t=-9.239， P<0.01）. The comparison between groups showed that the BPRS score of the experimental group was lower than that of the control group， and the SSMIS and IWB scores were higher than those of the control group （t=-3.899， 10.564， 9.690， P<0.01）. ConclusionThe implementation of family visit based on empowerment education may help to improve the psychotic symptoms of home rehabilitation schizophrenia， and improve their self-management ability and well-being.
RESUMO
@#Objective To evaluate the efficacy of video-assisted thoracoscopic sleeve lobectomy in the treatment of central non-small cell lung cancer. Methods The clinical data of 105 patients with central non-small cell lung cancer who underwent sleeve lobectomy surgery in the Second Hospital of Shanxi Medical University and Shanxi Cancer Hospital from December 2014 to December 2019 were retrospectively analyzed, including 83 males and 22 females, with an average age of 57.4 (32.6-77.8) years and weight of 62.5 (52.4-79.1) kg. Thirty-five patients received video-assisted thoracoscopic sleeve lobectomy (a group A), and 70 patients received traditional thoracotomy sleeve lobectomy (a group B). The operation time, intraoperative blood loss, number of lymph node dissection, postoperative complication rate, early postoperative mortality, total thoracic drainage volume at 24 hours, time of indwelling chest tube after operation, pain score at 24 hours after operation, postoperative hospital stay, postoperative short-term (1 month, 6 months and 1 year) quality of life score and postoperative 3-year survival rate of two groups were compared. Results There was statistical difference in the operation time (228.1±24.7 min vs. 175.0±23.7 min, P=0.02), postoperative complication rate (28.6% vs. 34.3%, P=0.04), postoperative pain score at 24 h (3.6±3.5 points vs. 5.9±2.0 points, P=0.03) and postoperative indwelling chest tube time (5.0±2.9 d vs. 8.4±2.1 d, P=0.04) between the two groups. There was no statistical difference in the intraoperative blood loss (182.5±36.9 mL vs. 189.8±27.5 mL, P=0.34), number of lymph node dissections (11.1±2.6 vs. 12.3±1.9, P=0.49), early postoperative mortality (2.9% vs. 4.3%, P=0.31), total thoracic drainage volume at 24 h after surgery (346.8± 91.1 mL vs. 329.8±101.4 mL, P=0.27), postoperative hospital stay (7.9±4.2 d vs. 8.5±3.4 d, P=0.39) and 3-year postoperative survival rate (68.6% vs. 72.9%, P=0.82) between the two groups. Conclusion Video-assisted thoracoscopic sleeve lobectomy for the treatment of central non-small cell lung cancer is safe and feasible. Compared with traditional thoracotomy for sleeve lobectomy, fewer postoperative complications occur, body recovers faster and the quality of life is higher within the postoperative 6 months. Besides, the 3-year survival rate can achieve similar oncological prognosis results.
