Purpose: The relationship between board certification, clinical guideline implementation, and quality of gastric cancer surgery remains unclear. Methods: A web-based questionnaire survey was administered to departments registered in the National Clinical Database (NCD) of Japan between October 2014 and January 2015. Quality indicators (QIs) based on the Donabedian model were evaluated. Structural QIs (e.g., affiliations with academic societies and board certifications) and process QIs (adherence to clinical practice guidelines for gastric cancer) were assessed using risk-adjusted odds ratios (AORs) for surgical mortality. Multivariable logistic regression models with a generalized estimating equation were used. Results: A total of 835 departments performing 40,992 distal gastrectomies and 806 departments performing 19,618 total gastrectomies responded. Some certified institutions and physicians showed significant associations, with lower AORs for surgical mortality. Important process QIs included pre- and postoperative abdominal CT scanning, endoscopic resection based on progression, curative resection with D2 dissection for advanced gastric cancer, laparoscopic surgery, and HER2 testing for patients with unresectable recurrent gastric cancer. Conclusions: Multiple structural and process QIs are associated with surgical mortality after gastrectomy in Japan. Measuring and visualizing QIs may enhance healthcare improvements.

Background: Pancreatic ductal adenocarcinoma (PDAC) often recurs early after radical resection, and such early recurrence (ER) is associated with a poor prognosis. Predicting ER is useful for determining the optimal treatment. Methods: One hundred fifty-three patients who underwent pancreatectomy for PDAC were divided into an ER group (n = 54) and non-ER group (n = 99). Clinicopathological factors were compared between the groups, and the predictors of ER and prognosis after PDAC resection were examined. Results: The ER group had a higher platelet count, higher platelet-to-lymphocyte ratio (PLR), higher preoperative CA19-9 concentration, higher SPan-1 concentration, larger tumor diameter, and more lymph node metastasis. The receiver operating characteristic (ROC) curve analysis identified cut-off values for PLR, carbohydrate antigen 19–9 (CA19-9), SPan-1, and tumor diameter. In the multivariate analysis, a high PLR, high CA19-9, and tumor diameter of >3.1 cm were independent predictors of ER after resection (all p < 0.05). When the parameter exceeded the cut-off level, 1 point was given, and the total score of the three factors was defined as the ER prediction score. Next, our new ER prediction model using PLR, CA19-9 and tumor diameter (Logit(p) = 1.6 + 1.2 × high PLR + 0.7 × high CA19-9 + 0.5 × tumor diameter > 3.1cm) distinguished ER with an area under the curve of 0.763, a sensitivity of 85.2%, and a specificity of 55.6%. Conclusions: ER after resection of PDAC can be predicted by calculation of a score using the preoperative serum CA19-9 concentration, PLR, and tumor diameter. [ABSTRACT FROM AUTHOR]

Background: Current guidelines recommend a comprehensive geriatric assessment (CGA) for the management of older adults with cancer. We evaluated the effect of CGA conducted by a geriatric oncology service (GOS) on the management of older adults with cancer. We also queried patients about their perceptions of the value of this process. Methods: This was a prospective quality assessment study of 498 consecutive older adults with cancer who were referred to the GOS from May 2020 through December 2021. Treating physicians requested a consultation and the GOS conducted a CGA and assessed patient preferences. The GOS provided recommendations on cancer treatment and geriatric interventions. Patient perspectives on the consultation were evaluated using collaboRATE and modified Patient Assessment of Care for Chronic Conditions (PACIC) subscales. Results: A 10‐item frailty index based on a CGA (FI‐CGA‐10) [Oncologist, 26, e1751 (2021)] in the 498 patients showed that 19% of patients were fit, 40% pre‐frail, and 41% frail. Prior to CGA the intent of the proposed cancer treatment was curative in 56% (n = 280), life‐extending in 40% (n = 201), and palliative in 3.4% (n = 17). After a CGA consultation, a cancer treatment decision was changed in 45% of patients. The intent of treatment after the CGA consultation was curative in 45%, life‐extending in 34%, and palliative in 21%. At least one referral to relevant disciplines was recommended for 88% of patients and was implemented in 43%. As part of the GOS consultation educational support was provided to 97% of patients. Based on the collaboRATE and PACIC tools, patients perceived the GOS consultation positively and helpful for facilitating shared decision‐making and patient‐centered care. Conclusion: Our institutional experience demonstrated the valuable effect of the CGA consultation on oncologic decision‐making and geriatric interventions in a patient‐centered manner.

Background: Compared with open standard gastrectomy (OG), laparoscopic gastrectomy (LG) did not result in inferior disease-free survival for early-stage and locally advanced gastric cancer (AGC). However, whether LG for AGC in elderly patients is more beneficial than OG is unclear. Methods: This study examined 458 patients with AGC. The mortality, morbidity, and prognosis were compared by age, gender, T and N factors, and pathological stage in the LG and OG groups using propensity score matching analysis. For the final analysis, 151 pairs of patients were selected from at each group. Results: The results showed that no significant difference in mortality and morbidity existed between the two groups. The 5-year relapse-free survival (RFS) rates were 70% and 62% in the LG and OG groups, respectively (p = 0.104). The 5-year RFS rates in patients with pathological stages I, II, and III who had undergone LG were 84%, 80%, and 55%, respectively, and 78%, 70%, and 45%, respectively, in those who had undergone OG (p < 0.005). The 5-year RFS rates in nonelderly patients who underwent LG or OG were 75% and 68%, respectively, and 58% and 40%, respectively, in elderly patients who underwent LG or OG (p < 0.005). Conclusion: The 5-year RFS rates in patients with AGC at each stage did not significantly differ between LG and OG. However, the benefits at 5-year RFS in patients who underwent LG compared with OG were larger in elderly patients than those in nonelderly patients. [ABSTRACT FROM AUTHOR]

Purpose: Selected patients with initially unresectable colorectal cancer (CRC) and liver metastases undergo conversion surgery after appropriate chemotherapy. The prognosis of these patients is good, with some even cured of the disease. This retrospective, single-institution study analyzes the clinical importance of patient characteristics on the outcomes of conversion hepatectomy. Methods: We evaluated 229 consecutive patients with initially unresectable CRC and liver metastasis, who underwent systemic chemotherapy. The patients were assigned to groups depending on conversion hepatectomy. Results: Conversion hepatectomy was performed in 30 patients (13.1%). The proportion of patients with extrahepatic metastasis was significantly lower in the conversion group than in the unresectable group (30.0 vs. 66.8%; P < 0.01). The rate of left-sided primary colorectal tumors was significantly higher in the conversion group than in the unresectable group (96.7 vs. 65.8%; P < 0.01). Multivariate analyses identified that left-sided tumors, no extrahepatic metastasis, H1 or H2 grade CLM, and treatment with molecular-targeted agents were associated with conversion hepatectomy (odds ratios: 16.314, 4.216, 7.631, and 4.070; P < 0.01). Overall survival was significantly longer in the conversion group than in the unresectable group (MST: 50.0 versus 14.7 months; P < 0.01). Conclusion: Left-sided primary tumors, absence of extrahepatic metastases, H1 or H2 grade, and use of molecular-targeted agents were associated with successful conversion hepatectomy; thus, patients with these characteristics may be candidates for conversion therapy.
