Study reveals overuse of surveillance colonoscopy in older adults with limited life expectancy
23 Mar, 2023 | 13:11h | UTCSummary: This study investigated the association between estimated life expectancy, surveillance colonoscopy findings, and follow-up recommendations among older adults. The study utilized data from the New Hampshire Colonoscopy Registry and included adults over 65 who underwent colonoscopy for surveillance after prior polyps.
Life expectancy was estimated using a validated prediction model and categorized into three groups: less than 5 years, 5 to less than 10 years, and 10 or more years.
Out of the 9,831 adults included in the study, 8% had advanced polyps or CRC. Among the 5,281 patients with available recommendations, 86.9% were advised to return for a future colonoscopy. Surprisingly, 58.1% of older adults with less than 5 years of life expectancy were also recommended to return for future surveillance colonoscopy.
The study concluded that many older adults with limited life expectancy are still recommended for future surveillance colonoscopy. This data could help refine decision-making about pursuing or stopping surveillance colonoscopy in older adults with a history of polyps.

RCT | Comparable 5-year relapse-free survival for laparoscopic vs. open distal gastrectomy in advanced gastric cancer
22 Mar, 2023 | 13:27h | UTCSummary: The JLSSG0901 randomized clinical trial aimed to compare the 5-year survival outcomes of laparoscopy-assisted distal gastrectomy (LADG) and open distal gastrectomy (ODG) with D2 lymph node dissection for locally advanced gastric cancer.
The study involved 507 patients from 37 institutes in Japan. The primary endpoint was 5-year relapse-free survival. The results showed that the 5-year relapse-free survival rates were 73.9% and 75.7% for the ODG and LADG groups, respectively, confirming the noninferiority of LADG, and no significant differences were observed in severe postoperative complications between the two groups.
The study concluded that LADG with D2 lymph node dissection, when performed by qualified surgeons, was proven noninferior to ODG, and could become a standard treatment for locally advanced gastric cancer.

Study suggests there is little added value from follow-up pelvic CT after treatment of hepatocellular carcinoma
23 Feb, 2023 | 13:39h | UTCSummary: The study investigated the added value of pelvic coverage at follow-up liver CT in detecting pelvic metastasis or incidental tumors in patients treated for hepatocellular carcinoma (HCC). The study found that the incidence of isolated pelvic metastasis or incidental pelvic tumor was low in patients treated for HCC. The cumulative rates of isolated pelvic metastasis and incidental pelvic tumor were 1.4% and 0.5%, respectively, at 3 years. Only baseline T stage was associated with an increased risk of isolated pelvic metastasis. The study concludes that excluding the pelvic scan can reduce radiation dose and decrease the workload for radiologists. However, the study also had limitations, such as being retrospective and single-center. Therefore, more research is necessary to study the optimal scanning strategy for the pelvis and the effect of pelvic CT coverage on survival in patients with HCC.

RCT | Laparoscopic proximal gastrectomy with double-tract reconstruction vs. total gastrectomy in upper-third early gastric cancer
23 Feb, 2023 | 13:29h | UTCSummary: This randomized trial examined whether laparoscopic proximal gastrectomy with double-tract reconstruction (LPG-DTR) is a superior surgical treatment compared to laparoscopic total gastrectomy (LTG) for patients with early gastric cancer (GC) in the upper third of the stomach. The study found that LPG-DTR resulted in significantly decreased amounts of vitamin B12 supplementation, but no significant difference in hemoglobin change compared to LTG. The study also found no difference in complication rates or overall and disease-free survival rates between the two groups. The study suggests that LPG-DTR may be a function-preserving procedure for the treatment of patients with upper-third early GC.
