Health-related quality of life after robot-assisted distal gastrectomy in early gastric cancer

Relationship Between Symptom Distress and Fatigue Characteristics in Patients with Gastric Cancer During 1 Month after Gastrectomy

This study's purpose was to describe changes in symptom distress and fatigue characteristics identifying which symptoms significantly impacted fatigue characteristics of patients with Gastric Cancer (GC) within 1 month after gastrectomy. A prospective longitudinal study was conducted. Patients with GC who were scheduled for gastrectomy were recruited from surgical outpatient clinics and surgery wards in northern Taiwan. Data were collected using a set of questionnaires before (T0) and 7 (T1) and 28 days (T2) after gastrectomy. Over all, 86 patients experienced mild levels of fatigue and symptom distress. The changes in worst fatigue and fatigue interference were greatest at T1. Anxiety had a significant negative effect on both worst fatigue and fatigue interference. Dry mouth, pain, and body image had significant deleterious effects on worst fatigue. The co-occurring symptoms affecting fatigue for patients with GC in the acute phase after gastrectomy should be actively assessed to ensure optimal fatigue management.

Assessment of Pain, Acceptance of Illness, Adjustment to Life, and Strategies of Coping with Illness among Patients with Gastric Cancer

Gastric cancer is the fourth leading cause of deaths in Poland. The standard treatment for non-advanced gastric cancer is surgery, which significantly reduces the quality of life of patients. The objective of the study was to evaluate the strategy of coping with pain and its control, acceptance of illness, and adjustment to living with cancer in patients suffering from gastric cancer. The analysis of the impact of socio-economic factors on the above-mentioned problems was also analyzed. The study was conducted among 93 patients diagnosed with gastric cancer, treated on an outpatient basis at the Oncology Center-Maria Skłodowska-Curie Institute in Warsaw in 2017-2018. The PAPI (paper and pencil interview) technique was used. The questionnaire interview included metric questions (socio-economic variables) and four psychometric tests: BPCQ (the Beliefs about Pain Control Questionnaire), CSQ (the Pain Coping Strategies Questionnaire), AIS (Acceptance of Illness Scale), and Mini-MAC (Mental Adjustment to Cancer) test. In the area of pain control, patients with gastric cancer assign the greatest role to internal factors (M = 16.34, SD = 4.93), although women obtained the highest value in the impact of physicians. In the area of coping with pain, patients most likely select the strategy of praying/hoping (M = 22.19, SD = 9.36). The mean value of acceptance of illness for patients with gastric cancer is M = 24.02, SD = 7.69, and it is not conditioned by any socio-economic variable. In the area of mental adjustment to illness, the highest values were obtained by positive reevaluation (M = 20.73, SD = 3.35) and fighting spirit (M = 20.68, SD = 3.98). Patients with gastric cancer control pain mainly through internal factors. The most frequently chosen strategy for coping with pain is praying/hoping, and positive reevaluation prevails in the field of mental adjustment. The results point to specific factors that can affect the patient's pain, quality of life, and treatment outcomes. Knowing the diversity of these factors, it is possible to plan specific psychotherapeutic activities for specific groups of people that could be a supplement to the standard treatment process.

Should robotic gastrectomy become a standard surgical treatment option for gastric cancer?

Robotic gastrectomy (RG) using the da Vinci Surgical System for gastric cancer was approved for national medical insurance coverage in Japan in April, 2018, and has been used increasingly since. We reviewed the current evidence on RG, open gastrectomy (OG), and conventional laparoscopic gastrectomy (LG) to identify differences in surgical outcomes between Japan and other countries. Briefly, three independent reviewers systematically reviewed the data collected from a comprehensive literature search by an independent organization and focused on the following nine endpoints: mortality, morbidity, operative time, estimated volume of blood loss, length of postoperative hospital stay, long-term oncologic outcome, quality of life, learning curve, and cost. Overall, the mortality rate of the three approaches did not differ, but RG and LG had less intraoperative blood loss and resulted in a shorter postoperative hospital stay than OG. RG had longer operative times and incurred higher costs than LG and OG. However, in Japan, RG may be more effective than LG and OG for decreasing morbidity. Further studies are needed to establish the specific indications for RG, optimal robotic setup, and dissection methods to best utilize the surgical robot.

Impact of Body Mass Index on the Quality of Life after Total Gastrectomy for Gastric Cancer

Purpose

We evaluated the impact of postoperative body mass index (BMI) shifts on the quality of life (QoL) following total gastrectomy in patients with gastric cancer.

Materials and Methods

QoL data collected from the European Organization for Research and Treatment of Cancer (EORTC) Quality of Life Questionnaire (QLQ)-C30 and QLQ-STO22 questionnaires were obtained from 417 patients preoperatively and 1 year after surgery. Patients were divided into two groups based on changes in BMI: group 1 comprised patientswhose BMIrange category dropped, and group 2 included patients who maintained or rose to a higher category compared to their preoperative BMI category.

Results

There were 276 patients in group 1 and 141 in group 2. QoLs with respect to the global health status and functional scales were not significantly different between the groups 1 year after surgery. However, there were significantly greater decreases in QoL in group 1 due to gastrointestinal symptoms, such as nausea and vomiting (p=0.008), appetite loss (p=0.001), and constipation (p=0.038). Of the QLQ-STO22 parameters, dysphagia (p=0.013), pain (p=0.012), reflux symptoms (p=0.017), eating restrictions (p=0.007), taste (p=0.009), and body image (p=0.009) were associated with significantly worse QoL in group 1 than in group 2 1 year after surgery.

Conclusion

Patients have significantly different QoLs depending on the BMI shift after total gastrectomy. Efforts to reduce the gap in QoL should include intensive nutritional support and restoration of dietary behaviors. Appropriate clinical and institutional approaches, plus active medical interventions, are required for maintaining patients' BMIs after surgery.

Robotic gastrectomy for gastric cancer

The number of robotic gastrectomy (RG) performed per year has been increasing, particularly in East Asia where the incidence of gastric cancer is high and approximately half of the cases are diagnosed as early gastric cancer. With articulated devices of RG, surgeons are able to perform every procedure more meticulously, which can result in less bleeding and damage to organs. There are many single arm and comparative studies, and these study showed similar trends, which included relatively less estimated blood loss and longer operation time following RG than laparoscopic gastrectomy (LG), equivalent number of harvested lymph nodes and similar length of postoperative hospital stay between RG and LG. Considering the results of these retrospective comparative studies, RG seems to be as feasible as LG in terms of early surgical outcomes. However, medical expense of RG is approximately twice as much as that of LG. Lack of solid evidence in terms of long-term outcomes is another problem. Considering the higher medical expenses associated with RG, its superiority in terms of long-term survival outcomes needs to be confirmed in the future for it to be accepted more widely.

Chronological Changes in Quality of Life after Distal Gastrectomy for Gastric Cancer

PURPOSE

Patient quality of life (QoL) may be severely disrupted following distal gastrectomy for gastric cancer. This issue should be addressed to improve postoperative care.

MATERIALS AND METHODS

QoL data from the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire, and its gastric cancer-specific module, were administered to 202 patients preoperatively, and 5 years postoperatively. Patients were classified into subgroups based on their answers to each questionnaire item: group I (good), answering "not at all"; group II (fair), answering "a little"; group III (poor), answering "quite a bit" or "very much."

RESULTS

At 5 years post-operation, the proportion of patients in group III on the functional scales ranged from 4.3% to 5.7%. The proportions of patients in group III with fatigue, insomnia, diarrhea, and financial difficulties were 8.9%, 9.0%, 11.5%, and 9.1%, respectively. The proportions of patients in group III with anxiety, dry mouth, body image concerns, and hair loss were 12.8%, 10.5%, 9.9%, and 12.6%, respectively. These proportions were less than 5% for other QoL symptom scales/items and for the gastric cancer-specific module.

CONCLUSIONS

Most patients reported good or fair QoL following surgery. However, symptom management of fatigue, insomnia, diarrhea, anxiety, dry mouth, body image, and hair loss should be specifically targeted for long-term patient care in approximately 10% of patients.

Survival benefit of additional surgery after noncurative endoscopic resection in patients with early gastric cancer

BACKGROUND AND AIMS

Excellent long-term outcome is expected for early gastric cancers (EGCs) after endoscopic submucosal dissection (ESD). However, if ESD is considered noncurative at the pathologic evaluation, additional surgery is recommended. We evaluated whether long-term outcome is compromised if additional surgery is not performed for EGCs that are out-of-indication.

METHODS

We retrospectively analyzed a cohort of patients with EGC not meeting ESD indications whose initial treatment was either ESD (n = 219) or surgery (n = 1799). Among them, 127 patients who underwent additional surgery after initial ESD and 67 patients who did not were matched using propensity scores to patients who initially underwent standard surgery, at a 1:1 ratio. Overall mortality and gastric cancer recurrence were compared.

RESULTS

The overall mortality and gastric cancer recurrence rates were not significantly different between the 127 patients who underwent initial ESD with additional surgery and the corresponding initial standard surgery patients. However, the overall mortality of the 67 patients who underwent ESD without additional surgery (5-year mortality, 26.0%; 95% CI, 13.5%-49.9%) was higher than that of the matched initial standard surgery patients (5-year mortality, 14.5%; 95% CI, 6.3%-33.6%; P = .04). Gastric cancer recurrence was also higher in ESD patients without additional surgery (5-year recurrence, 17.0%; 95% CI, 7.6%-37.8%) than in the matched initial surgery group (0%; P = .002). In multivariate analyses, ESD without additional surgery was a significant risk factor for overall mortality and gastric cancer recurrence.

CONCLUSIONS

Additional surgery should be encouraged after non-curative ESD to obtain long-term outcomes comparable with those of initial standard surgery. (Clinical trial registration number: NCC2015-0093.).

Technique of totally robotic delta-shaped anastomosis in distal gastrectomy

BACKGROUND:

We aimed to clarify the utility of delta-shaped anastomosis (Delta), an intracorporeal Billroth-I anastomosis-based reconstruction technique used after laparoscopy-assisted distal gastrectomy (LADG), in robot-assisted distal gastrectomy (RADG).

METHODS:

RADG was performed in patients with clinical Stage I gastric cancer, and reconstruction was performed using Delta. The Delta procedure was the same as that performed after LADG, and the operator practiced the procedure in simulated settings with surgical assistants before the operation. After gastrectomy, the scope and robotic first arm were reinserted from separate ports on the right side of the patient. Then, a port on the left side of the abdomen was used as the assistant port from which a stapler was inserted, with the robotic arm in a coaxial mode. The surgical assistant performed functional end-to-end anastomosis of the remnant stomach and duodenal stump using a powered stapler.

RESULTS:

The mean anastomotic time in four patients who underwent Delta after RADG was 16.5 min. All patients were discharged on the post-operative day 7 without any post-operative complications or need for readmission.

CONCLUSIONS:

Pre-operative simulation, changes in ports for insertion of the scope and robotic first arm, continuation of the coaxial operation, and use of a powered stapler made Delta applicable for RADG. Delta can be considered as a useful reconstruction method.

Chronological Changes of Quality of Life in Long-Term Survivors after Gastrectomy for Gastric Cancer

Purpose

A few studies have prospectively evaluated changes in quality of life (QoL) after surgery in short-term survivors; however, no prospective study has evaluated the longitudinal changes in QoL in long-terms survivors. We prospectively evaluated the chronological changes in QoL after a gastrectomy over a 5-year postoperative period in a large group of patients.

Materials and Methods

QoL data from the European Organization for Research and Treatment of Cancer QLQ-C30 and the QLQ-STO22 questionnaires were obtained from 254 patients who completed the entire series of QoL assessments preoperatively and at 1, 2, 3, 4, and 5 years after surgery.

Results

There was no statistically significant change in global health status/QoL during the 5-year postoperative period. Decreases in QoL from upper gastrointestinal symptoms including diarrhea (p < 0.001), dysphagia (p < 0.001), reflux symptoms (p=0.029), and eating restrictions (p < 0.001) were observed among the long-term survivors. Decreased physical functioning (p < 0.001), role functioning (p < 0.001), and cognitive functioning (p < 0.001), along with fatigue (p=0.045) and a poor body image (p=0.003), negatively impacted the patients’ QoL for a long time.

Conclusion

Management of gastrointestinal symptoms should be specifically targeted as a part of long-term patient care after a gastrectomy. Proper nutritional care will improve food intake resulting in weight gain and improved physical functioning, role functioning, and body image. In addition, patients should be encouraged to preserve self-esteem and maintain social activity.

Comparison of Quality of Life and Nutritional Status in Gastric Cancer Patients Undergoing Gastrectomies

The aim of this study was to compare the quality of life (QoL) depending on the postoperative survival period or nutritional status in gastric cancer patients. Surviving gastric cancer patients (n = 222) after the gastrectomy were included in the study at Soonchunhyang University Bucheon Hospital from April 2010 to August 2012. The Korean versions of the European Organization for Research and Treatment of Cancer (EORTC) Quality of Life Questionnaire Core 30 (QLQ-C30) and a gastric cancer-specific module, the EORTC QLQ-STO22, were used to assess the QoL. The postoperative survival period of the patients fell into two groups; the less-than-1-year group or the more-than-1-year group, and the nutritional status of the patients fell into three groups by a score of patient generated-subjective global assessment (SGA)-A, B, and C. As a result, the rate of malnutrition was 34.5% in the less-than-1-year group and 19.8% in the more-than-1-year group, respectively. Score for the fatigue (p = 0.006), loss of appetite (p = 0.002), reflux (p = 0.027) and body image (p = 0.004) in which the QoL was significantly lower in the less-than-1-year group than in the more-than-1-year group. The score of QoL according to the nutritional status of all subjects, overall health status (p = 0.043), physical functioning (p = 0.016), fatigue (p = 0.006), pain (p = 0.028), loss of appetite (p = 0.017), reflux (p = 0.003), eating restriction (p = 0.002), anxiety (p = 0.010), and body image (p = 0.001) was significantly lower in the SGA-C group than in other SGA groups. These results suggest that the nutritional status of the gastrectomy patients with stomach cancer may impact on their QoL. It is necessary to to develop nutritional intervention to improve QoL in gastric cancer patients with postoperative malnutrition.

Robotic surgery for gastric cancer

Laparoscopic gastrectomy is a widely used minimally invasive surgery for gastric cancer. However, skillful techniques are required to perform lymph node dissection using straight shaped forceps, particularly for D2 dissection. Robotic surgery using the da Vinci surgical system is anticipated to be a powerful tool for performing difficult techniques using high-resolution three-dimensional (3D) images and the EndoWrist equipped with seven degrees of freedom. Attempts are being made to apply robotic surgery in gastrectomy procedures mainly in Japan, South Korea, and Europe. Although definite superiority to laparoscopic gastrectomy is yet to be proven, robotic surgery has been reported to have a shorter learning curve and offer more precise dissection for total gastrectomy. Hence, its oncological efficacy needs to be verified in a clinical trial.
