Clinical Study on Laparoscopic Gastrectomy for Early Gastric Cancer (COACT_0301) (NCC052)

2012년 5월 22일 업데이트: Young-Woo Kim, National Cancer Center, Korea

Prospective Randomized Trial of Laparoscopy-assisted Distal Gastrectomy (LADG) Versus Open Distal Gastrectomy (ODG) in Patients With Early Gastric Cancer (EGC)

Rationale: For the treatment of early gastric cancer (EGC) in the distal portion of the stomach, subtotal gastrectomy and lymph node dissection has been a standard operation. With the increasing tendency toward minimally invasive surgery, there has been an effort to apply minimally invasive techniques to the treatment of EGC. Laparoendoluminal mucosectomy and lesion-lifting gastric wedge resection have been developed for this purpose. However, these methods have the disadvantage of limited indications according to the size, shape and depth of invasion. Kitano et al. performed the first laparoscopy-assisted subtotal gastrectomy with lymph node dissection and manual anastomosis with anterior wall lifting method for a patient with EGC. In 1995, Uyama et al. and Nagai et al. performed laparoscopy-assisted subtotal gastrectomy with lymph node dissections using an automatic stapler instead of manual anastomosis for the gastroduodenal anastomosis. It has been possible to maintain an adequate distance from the lesion to the proximal and distal margins of resection, to perform radical lymph node dissection, and to achieve excellent postoperative recovery. However, there is a very limited evidence of superiority of laparoscopic gastrectomy over open surgery. There is only one interim report of randomized clinical trial of comparing laparoscopic gastrectomy and open gastrectomy. A well-designed clinical study to prove the benefit and safety is definitely needed Objective: to compare Laparoscopy - assisted Distal Gastrectomy (LADG) with Open Distal Gastrectomy (ODG) in terms of survival, recovery, pain, complications, and quality of life (QOL) Hypothesis: LADG is beneficial in QOL, pain, recovery, complications while maintaining equivalent survival with ODG

상세 설명

  1. Randomization

    Randomization is done by person who is not involved in study. So it is done by the person in Center for Clinical Trial in National Cancer Center. The patient is enrolled in the out-patient clinic after getting informed consent of the clinical study from the patient. Surgeon factor is not considered as a randomization factor because this clinical study will be performed intramurally. In Center for Gastric Cancer, National Cancer Center, Surgical techniques and extent of resections are generally standardized and surgical outcomes are same in terms of complication and recovery.

  2. Follow-up schedule

    Patients are followed up in the outpatient department at four weeks, three months, six months, and twelve months after the operation, and every six months thereafter. On each visit, history was reviewed and physical examination was done. A complete blood count (CBC) and serum chemistry were evaluated also. An esophago-gastro-duodenoscopy (EGD) was performed at three months after the operation and yearly thereafter. Abdominal computed tomography (ACT) was evaluated annually.

  3. Assessment of QOL The European EORTC QLQ-C30 (version 3.0) questionnaire is a 30-item cancer-specific integrated system for assessing the health-related QOL of cancer patients. The questionnaire incorporates five scales of function (physical, role, cognitive, emotional and social), three symptom scales (fatigue, pain and nausea and vomiting), a global health and QOL scale, and single items for the assessment of additional symptoms commonly reported by cancer patients (e.g., dyspnea, appetite loss, sleep disturbance, constipation and diarrhea), as well as the perceived financial impact of the disease and treatment. All items were scored on four-point Likert scales, with the exception of two items in the global health QOL scale, which used modified seven-point linear analog scales. The EORTC QLQ-STO22 with a 22-item stomach cancer-specific questionnaire was also used. It incorporates five hypothesized scales-(dysphasia, eating restrictions, pain, reflux and anxiety) and four single items (having a dry mouth, body image, taste, and hair loss) covering disease and treatment-related symptoms and specific emotional consequences of gastric cancer.12 All instruments of the questionnaire were administered preoperatively and postoperatively at seven days, 30 days, 90 days and yearly. Those time points were chosen at usual follow-up schedule for every gastrectomized patients in our institute, to maximize compliance for the questionnaire, and to compare other parameters at the same time.
  4. Statistical analyses The EORTC QLQ-C30 symptom subscale and the EORTC QLQ-STO22 subscale scores are reported using a scale from 0 to 100. Statistical analyses of the QOL outcomes evaluated the differences between the LADG and the ODG groups with respect to the overall changes from the preoperative scores (baseline) to those obtained at follow-up. To adjust for possible baseline differences, we included the baseline values in the model. All comparisons between groups were based on 'intent-to-treat' analyses in which patients were analyzed according to their assigned treatment group. Categorical variables were compared using the χ2 test, and continuous variables were analyzed using the Student's t-test. Analysis of Covariance (ANCOVA) with repeated measures was used to compare the two groups of patients with respect to overall changes in their short term quality of life after the surgery. The SAS (SAS Institute Inc., Cary, NC, USA) program called 'PROC GLM' was used.
