Do we understand the pathophysiology of endometrial cancer?

Endometrial carcinoma is the fourth most common cancer in U.K. women. Previous literature describes local, haematological or lymphatic dissemination to common sites including vaginal vault, lungs, liver, bones and brain. The authors present two unusual cases of endometrial cancer metastases to the psoas major muscle and laparoscopic port sites. Case 1 involves a 71-year-old female who underwent total abdominal hysterectomy, bilateral salpingo-oophorectomy and peritoneal washings (TAH, BSO, PW) for Grade 1 endometrial cancer, Stage lB. Three years later she represented with lower back and right hip pain, with MRI imaging revealing psoas muscle metastases. Case 2 describes a 60-year-old female who underwent laparoscopic-assisted vaginal hysterectomy (LAVH), BSO+ PW for Grade 1 endometrial cancer, Stage 1B. Three years postoperatively she presented with a lateral abdominal mass overlying the laparoscopic port site scar, which was Grade 1 endometrial cancer on biopsy. These rare metastatic locations question our traditional understanding of the pathophysiology of endometrial carcinoma.

Remifentanil as single agent to facilitate awake fibreoptic intubation in the absence of premedication.

Remifentanil is increasingly being used as the primary agent to provide sedation during awake fibreoptic nasal intubation. In this observational study, we aimed to determine the optimal effect site concentration of remifentanil, using a target controlled infusion based on the Minto pharmacological model, to provide optimal safe intubation conditions without the use of other sedatives/premedication and/or spray-as-you-go local anaesthesia. Twenty patients with anticipated difficult airway participated in the study. Good intubating conditions were achieved in all patients with mean (SD) effect site concentration of 6.3 (3.87) ng.ml(-1) of remifentanil recorded at nasal endoscopy and 8.06 (3.52) ng.ml(-1) during tracheal intubation. No serious adverse event occurred during any of these procedures. These preliminary findings suggest that this is a feasible and safe technique for awake fibreoptic nasal intubation.

The effect of neoadjuvant chemotherapy on physical fitness and survival in patients undergoing oesophagogastric cancer surgery.

BACKGROUND: Neoadjuvant chemotherapy (NAC) followed by surgery for resectable oesophageal or gastric cancer improves outcome when compared with surgery alone. However NAC has adverse effects. We assess here whether NAC adversely affects physical fitness and whether such an effect is associated with impaired survival following surgery. METHODS: We prospectively studied 116 patients with oesophageal or gastric cancer to assess the effect of NAC on physical fitness, of whom 89 underwent cardiopulmonary exercise testing (CPET) before NAC and proceeded to surgery. 39 patients were tested after all cycles of NAC but prior to surgery. Physical fitness was assessed by measuring oxygen uptake (VO2 in ml kg(-1) min(-1)) at the estimated lactate threshold (θL) and at peak exercise (VO2 peak in ml kg(-1) min(-1)). RESULTS: VO2 at θL and at peak were significantly lower after NAC compared to pre-NAC values: VO2 at θL 14.5 ± 3.8 (baseline) vs. 12.3 ± 3.0 (post-NAC) ml kg(-1) min(-1); p ≤ 0.001; VO2 peak 20.8 ± 6.0 vs. 18.3 ± 5.1 ml kg(-1) min(-1); p ≤ 0.001; absolute VO2 (ml min(-1)) at θL and peak were also lower post-NAC; p ≤ 0.001. Decreased baseline VO2 at θL and peak were associated with increased one year mortality in patients who completed a full course of NAC and had surgery; p = 0.014. CONCLUSION: NAC before cancer surgery significantly reduced physical fitness in the overall cohort. Lower baseline fitness was associated with reduced one-year-survival in patients completing NAC and surgery, but not in patients who did not complete NAC. It is possible that in some patients the harms of NAC may outweigh the benefits. Trials Registry Number: NCT01335555.

Anaesthesia for spinal surgery in adults.

The spectrum of spinal surgery in adult life is considerable. Anaesthesia for major spinal surgery, such as spinal stabilization following trauma or neoplastic disease, or for correction of scoliosis, presents a number of challenges. The type of patients who would have been declined surgery 20 yr ago for medical reasons, are now being offered extensive procedures. They commonly have preoperative co-morbid conditions such as serious cardiovascular and respiratory impairment. Airway management may be difficult. Surgery imposes further stresses of significant blood loss, prolonged anaesthesia, and problematical postoperative pain management. The perioperative management of these patients is discussed. The advent of techniques to monitor spinal cord function has reduced postoperative neurological morbidity in these patients. The anaesthetist has an important role in facilitating these methods of monitoring.
