Clinical and cost outcomes of a polyethylene glycol (PEG)-coated patch versus drainage after axillary lymph node dissection in breast cancer: results from a multicentre randomized clinical trial.

BACKGROUND: The aim of this study was to compare the clinical outcomes between breast cancer patients who underwent axillary lymph node dissection with postoperative management using a polyethylene glycol-coated patch versus axillary drainage. The direct costs associated with both postoperative management strategies were also evaluated. METHODS: This was a multicentre RCT in women with breast cancer who underwent axillary lymph node dissection (ClinicalTrials.gov identifier: NCT04487561). Patients were randomly assigned (1 : 1) to receive either drainage or a polyethylene glycol-coated patch as postoperative management. The primary endpoints were the need for an emergency department visit for any event related to the surgery and the rate of seroma development. RESULTS: A total of 227 patients were included , 115 in the patch group (50.7 per cent) and 112 (29.4 per cent ) in the drainage group. The incidence of emergency department visits was significantly greater for patients with drainage versus a polyethylene glycol-coated patch (incidence rate difference 26.1 per cent, 95 per cent c.i. 14.5 to 37.7 per cent; P < 0.001). Conversely, the seroma rate was significantly higher in the polyethylene glycol-coated patch group (incidence rate difference 22.8 per cent, 95 per cent c.i. 6.7 to 38.9 per cent; P < 0.0055). Compared with drainage, using a polyethylene glycol-coated patch resulted in cost savings of €100.41 per patient. An incremental cost-effectiveness ratio analysis found that drainage was associated with an incremental cost-effectiveness ratio of €7594.4 for no need for hospital admission and €491.7 for no need for an emergency department visit. CONCLUSION: Compared with patients who received drainage after axillary lymph node dissection, the use of a polyethylene glycol-coated patch resulted in a higher rate of seroma, but a lower number of postoperative outpatient or emergency department visits and thus a reduction in overall costs.

Results of implementation of a fast track pathway for diagnosis of colorectal cancer.

INTRODUCTION: fast track pathways for diagnosis of cancer intend to decrease delays in diagnosis and treatment of cancer. It is recommended to initiate treatment in a period no longer than 30 days since admission in these circuits. AIMS: to know the characteristics and fluency of our Fast Track Diagnostic Pathway (FTDP) for Colorectal Cancer (CRC), with special attention to those patients selected for surgical treatment as a first choice. MATERIAL AND METHOD: all patients who entered the FTDP for CRC during a period of 2 years (2008-2009) were analyzed as well as the rest of patients also diagnosed with CRC but never seen in the FTDP. RESULTS: of the 316 patients referred to the FTDP only 78 (24.7%) were diagnosed as having some kind of cancer derived from the digestive system. At the end 61 patients (19.3%) were diagnosed with CCR. The time interval from entry into the FTDP to the first hospital visit was 3 days (range 1-8), and the interval until colonoscopy was performed was 11.5 days (range 1-41). Fourteen (41.1%) of those patients chosen for surgery were operated on in a period lesser than 30 days while 28 patients (82.3%) underwent surgery before day 45 since admission into the circuit. CONCLUSIONS: though the functioning of the FTDP is acceptable, any increase in number of patients can generate delays. For this reason it is advisable to have a team to assure a good functioning of the FTDP. A proper follow-up of the whole process will possibly avoid unnecessary delays and it will improve coordination of the different phases of the fast track pathway and treatment. As the diagnostic outcome is poor it is mandatory to implement alternatives programs like screening of asymptomatic population, allowing an early detection of this condition.

Muscle strength, physical performance, and metabolic changes after subtotal parathyroidectomy for secondary hyperparathyroidism.

BACKGROUND: Hyperparathyroidism in patients on chronic hemodialysis presents with bone pain, pruritus, and extra-skeletal calcifications. Little attention has been paid to low plasma protein concentrations and muscle weakness in these patients. The present study was undertaken to characterize the impact of subtotal parathyroidectomy for chronic hemodialysis on body composition, muscle strength, plasma proteins, quality of life, and long-term clinical course. METHODS: We performed a prospective observational before-after assessment study of consecutive chronic hemodialysis patients referred for parathyroidectomy. Patients were investigated at baseline before parathyroidectomy and then at 1 and 6 months after surgery, with the aim to assess changes in metabolic parameters, body composition by bioimpedance, muscle strength, and quality of life (36-items Short Form Health Survey questionnaire). Follow-up was terminated when patients reached 1 of the 3 pre-defined end points: recurrence of secondary hyperparathyroidism, transplantation, or death. RESULTS: A group of 23 patients on hemodialysis were included. Preoperative handgrip strength was diminished by 52.4 ± 17%. After parathyroidectomy, a drop of immunoreactive parathyroid hormone concentrations (1,153 vs 237 pg/mL; P < .001) was observed together with increases in plasma protein (total: 6.8 vs7.8 g/dL, s-albumin 3.7 vs 4.4 g/dL and prealbumin: 31.7 vs 35.2 mg/dL; P < .001), handgrip strength (18.3 vs 22.9 kg: P = .001) as well as an improvement in physical dimension (32.9 vs 35.6; P = .004) and vitality (32.3 vs 47.1; P = .002) domains of the 36-items Short Form Health Survey questionnaire. After10 years, one-third of the patients had died, one-third of the patients had a recurrence of secondary hyperparathyroidism, and one-third of patients had received a kidney transplant and maintained a normal parathyroid function. CONCLUSION: Subtotal parathyroidectomy improves protein metabolic markers, muscle strength, and physical performance in chronic hemodialysis patients.
