This work aimed to determine the benefits and risks of prophylactic feeding tubes for adult patients with squamous cell carcinoma of the head and neck who receive combined chemotherapy and radiotherapy with curative intent and to make recommendations on the use of prophylactic feeding tubes and the provision of adequate nutrition to this patient population.
A national multidisciplinary panel conducted a systematic review of the evidence and formulated recommendations to guide clinical decision-making. The draft evidence summary and recommendations were distributed to clinicians across Canada for their input.
No randomized controlled trials have directly addressed this question. Evidence from studies in the target population was limited to seven descriptive studies: two with control groups (one prospective, one retrospective) and five without control groups. Results from ten controlled studies in patients treated with radiotherapy alone were also reviewed.
The available evidence was insufficient to draw definitive conclusions about the effectiveness of prophylactic feeding tubes in the target patient population or to support an evidence-based practice guideline. After review of the evidence, of guidelines from other groups, and of current clinical practice in Canada, the multidisciplinary panel made consensus-based recommendations regarding comprehensive interdisciplinary clinical care before, during, and after cancer treatment. The recommendations are based on the expert opinion of the panel members and on their understanding of best clinical practice.
本研究旨在确定接受以治愈为目的的联合化疗和放疗的头颈部鳞状细胞癌成年患者预防性置管的获益和风险,并针对该患者人群的预防性置管和充足营养供给提出使用建议。
一个多学科的全国委员会对证据进行了系统回顾,并制定了建议,以指导临床决策。证据概要和建议草案分发给加拿大各地的临床医生征求意见。
没有随机对照试验直接针对这一问题。目标人群研究中的证据仅限于七项描述性研究:两项有对照组(一项前瞻性,一项回顾性),五项无对照组。还回顾了单独接受放疗的患者的十项对照研究的结果。
目前的证据不足以对目标患者人群中预防性置管的有效性得出明确结论,也无法支持循证实践指南。在审查证据、其他团体的指南以及加拿大当前的临床实践后,多学科委员会就癌症治疗前后的综合多学科临床护理提出了基于共识的建议。这些建议基于小组成员的专业意见以及他们对最佳临床实践的理解。
