目的探讨舌癌患者根治术后实施整体护理的效果。方法将入住我院50例接受舌癌舌颌颈联合根治术的患者,按照随机数字表法分为观察组和对照组各25例,对照组患者应用常规护理方法,观察组患者应用整体护理方法,比较两组患者护理的口腔清洁度、术后语言表达效果及满意度。结果观察组患者的口腔清洁度优良率高于对照组,两组比较差异有统计学意义(χ~2=9.44,P0.05);观察组患者的术后语言效果优于对照组,两组比较差异有统计学意义(χ~2=5.09,P0.05);观察组患者满意度高于对照组,两组比较差异有统计学意义(χ~2=9.92,P0.05)。结论通过整体护理的实施,有助于增强舌癌患者术后治疗信心,促进康复及提高他们的生活质量,值得临床推广。  相似文献

Objective: To quantify distress in men treated with radical prostatectomy (RP) or active surveillance (AS). Methods: In a retrospective cross-sectional design, we assessed men through questionnaire and investigator-designed questions. Results: RP patients worried more about cancer spread than AS patients. RP patients were influenced by friends for treatment decision, whereas AS patients were influenced by urologists. RP group report declines in intimacy and instrumental. AS men worried more about future health and dying than post-RP men. Conclusion: Fear of disease progression may be a motivating factor in choosing RP. AS patients adhere to their treatment decision in spite of distress.  相似文献

The management of recurrent prostate cancer after radiotherapy or brachytherapy is non-standardized and rapidly evolving. Local recurrence is observed on average in 30% of cases several years following irradiation. A key challenge is to determine the site of recurrence and imaging (MRI and PET choline) coupled to prostate biopsies are important to confirm the local character. Salvage therapy performed by the urologist can then control the situation. Radical prostatectomy subject to strict technical conditions is one of the most efficient local treatments, however it comes at the cost of significant urinary morbidity; minimally invasive therapies (focused ultrasound and cryotherapy) have also their place in specific indications. Each clinical situation should be discussed in pluridisciplinary meetings integrating the oncologic and functional status at recurrence, the risk/benefit ratio of each treatment, the patient's wishes and probability of survival.  相似文献

ObjectiveAsian patients tend to have higher stage prostate cancer at diagnosis compared with patients of other races. This article aims to investigate the use of four-port extraperitoneal laparoscopic radical prostatectomy (EPLRP) as the first step in a multimodality treatment strategy for Asian patients with high-risk prostate cancer (HRPC).Materials and methodsA cohort of 202 patients underwent EPLRP between January 2006 to January 2016, of whom 122 (60.3%) had HRPC as defined by D'Amico classification: clinical T stage ≥ cT2c or PSA level ≥ 20 ng/mL or biopsy Gleason sum ≥ 8). All patients underwent proper preoperative staging. The median age was 68 years (48–82), PSA level 17.8 ng/mL (3.3–191.1), and biopsy Gleason sum 7 (6–10). All patients underwent pelvic lymphadenectomy, and some underwent neurovascular bundle preservation according to their risk category.ResultsPerioperative outcomes included a median operative time of 185 min (65–380), total blood loss 150 ml (30–500), postoperative hospitalization 10 days (6–25), and urethral catheterization time 7 days (4–22). No patient was converted to open surgery. Median specimen weight was 42 g (19–124), lymph node yield was 10 (0–35) with 11.5% positivity and a positive surgical resection margin rate of 28.7%. The median follow-up period was 37 months (6–129). 96.7% of patients achieved continence and 53.8% of the 39 potent patients prior to surgery maintained their sexual potency at one year after EPLRP. The 5-year cancer-specific, overall, and biochemical recurrence-free survival rates were 98.8%, 92.2%, and 68.7%, respectively.ConclusionExtraperitoneal laparoscopic radical prostatectomy has low morbidity, and can provide fair functional and oncological outcomes as the first step of a multimodality treatment strategy for high-risk prostate cancer in Asian.  相似文献

Despite significant advances in patient selection as well as surgical technique over the past few decades, it is still not uncommon for patients with urological malignancy and positive surgical margins to be observed. Meanwhile, intraoperative pathology consultation with frozen section assessment, which generally provides useful information for the optimal procedure, has been widely utilized for the assessment of surgical margins during urological surgeries. Thus, it remains unanswered whether intraoperative frozen section assessment has an impact on final surgical margin status as well as long‐term oncological outcomes. The present review summarizes and discusses available data assessing the utility of frozen section assessment of the surgical margins during urological surgeries, such as radical prostatectomy, partial nephrectomy and radical cystectomy. The current findings suggest that select patients might benefit from the routine frozen section assessment.  相似文献
