Preoperative Exercise for Patients Undergoing Complex Cancer Surgery

Treatment for people with cancer of the lung or the oesophagus (food-pipe) often involves surgery. This surgery is complex and there is a high risk that patients will develop severe complications afterwards, leading to a longer hospital stay and higher hospital costs, and impacting greatly on recovery and quality of life. If patients' lungs and heart can be optimised before surgery, then recovery may be improved. While fitness can be improved by exercise, the lead-in time to surgery following a cancer diagnosis is often very short, and research is needed to examine what types of exercise might be most effective at increasing fitness over a short period. This project will investigate if high intensity interval training (HIIT) can increase fitness levels in people scheduled for surgery for cancer of the oesophagus or the lungs. HIIT alternates between periods of high intensity exercise, cycling on a stationary bike, followed by a period of more relaxed exercise. This approach is known to improve fitness but has not previously been investigated in patients awaiting complex cancer surgery. Groups will be compared for changes in pre-surgery fitness levels, any complications they may experience after surgery, general physical recovery after surgery and the cost of care after surgery. The investigators anticipate that patients who undergo HIIT before surgery will have less complications and better recovery after surgery, a significantly improved quality of life, and lower costs of care.

Laparoscopic D2 Distal Gastrectomy Following Neoadjuvant Chemotherapy for Locally Advanced Gastric Cancers

Gastric cancer is the third major cancer of global cancer-related death. In China, the early diagnosis rate of gastric cancer is relatively low, and most patients are with locally advanced tumor stage. The neoadjuvant chemotherapy (NAC) can bring the survival advantage for gastric cancer patients with locally advanced tumor stage. The primary goal of NAC is to control the micrometastasis and/or progression of the primary lesion in order to improve potential of radical gastrectomy. NAC is recommended for patients with locally advanced stage (T2-4Nx) according to the latest NCCN Gastric Cancer Guidelines. Laparoscopy distal gastrectomy (LDG) can achieve a better postoperative short-term recovery than the traditional open distal gastrectomy (ODG), which can reduce the intraoperative blood loss and to shorten the postoperative hospital stay. Therefore, Enhanced Recovery After Surgery program of gastric cancer surgery recommends the use of minimally invasive surgery. For long-term survival outcomes, there is limited evidence supported that laparoscopic gastrectomy is comparable open gastrectomy. Therefore, due to the lack of high-quality prospective clinical trial results, whether advanced tumor is suitable for laparoscopic surgery is still controversial. Therefore, some multi-center prospective randomized controlled trials have been carried out, compared safety and long-term survival outcome between laparoscopic and open gastrectomy in locally advanced gastric cancer patients. CLASS-01 trials reported that for locally advanced gastric cancers, laparoscopic D2 distal gastrectomy is safe and feasible. Patient's surgical tolerance and stress response may be inhibited after the treatment of NAC. The aim of this trial is to confirm the safety of laparoscopy distal D2 radical gastrectomy for the treatment of after neoadjuvant chemotherapy gastric cancer patients (cT3-4a, N+, M0) in terms of postoperative complications.
