Abstract
Osteoporosis is a common systemic disease of the skeleton, characterized by compromised bone mass and strength, consequently leading to an increased risk of fragility fractures. In women, the disease mainly occurs due to the menopausal fall in estrogen levels, leading to an imbalance between bone resorption and bone formation and, consequently, to bone loss and bone fragility. Moreover, osteoporosis may affect men and may occur as a sequela to different diseases or even to their treatments. Despite their wide prevalence in the general population, the skeletal implications of many gastrointestinal diseases have been poorly investigated and their potential contribution to bone fragility is often underestimated in clinical practice. However, proper functioning of the gastrointestinal system appears essential for the skeleton, allowing correct absorption of calcium, vitamins, or other nutrients relevant to bone, preserving the gastrointestinal barrier function, and maintaining an optimal endocrine-metabolic balance, so that it is very likely that most chronic diseases of the gastrointestinal tract, and even gastrointestinal dysbiosis, may have profound implications for bone health. In this manuscript, we provide an updated and critical revision of the role of major gastrointestinal disorders in the pathogenesis of osteoporosis and fragility fractures.

Abstract
Some authors have suggested that a relationship exists between gastrectomy for gastric cancer and metabolic bone disorders. However, few studies have investigated metabolic bone disorders after gastrectomy for gastric cancer in detail. Thus, we reviewed the findings of our recent prospective study and those of other reports on this subject. Osteoporosis and osteomalacia have been observed after gastrectomy and appear to be caused by reduced food intake and absorption, and steatorrhea. Moreover, the incidence of fracture is high after gastrectomy, although subtotal or total gastrectomy and reconstruction for gastric cancer have not been identified as significant risk factors for decreased bone mineral density (BMD). Recently, we reported that the BMD decreased significantly within 12 months after gastrectomy for gastric cancer in both male and female patients, but there was no significant gender-related difference in the rate of change in BMD. More than 1 year after gastrectomy, the steep decrease in the BMD stabilized and normal levels of 1,25(OH)2 vitamin D3 were maintained, despite the lack of precursor for 1,25(OH)2 vitamin D3 synthesis after gastrectomy. Alendronate therapy might be effective and prevent postgastrectomy metabolic bone disorders; however, the optimal treatment and prevention strategy for this bone disorder has not been delineated.

Incidence and risk factors of osteoporotic status in outpatients who underwent gastrectomy for gastric cancer. JGH OPEN 2020; 4:903-908. [PMID: 33102762 PMCID: PMC7578282 DOI: 10.1002/jgh3.12347] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 11/27/2019] [Revised: 03/14/2020] [Accepted: 04/08/2020] [Indexed: 02/06/2023]
Abstract
Background and Aim Disorders in bone metabolism have long been recognized as typical sequelae of gastrectomy; however, the pathogenesis has not been fully elucidated, resulting in a variation of reported incidence. This study aimed to evaluate current bone health by measuring bone mineral density (BMD) in patients treated by gastrectomy for gastric cancer, with a focus on incidence and risk factors of osteoporosis. Methods The study enrolled 81 patients who underwent gastrectomy for gastric cancer at Kochi Medical School. BMD of the lumbar spine was measured by dual‐energy X‐ray mineral absorptiometry, with the results expressed as a percentage of the young adult mean (YAM). Clinical data were also obtained to investigate associations with BMD. Results Of the 81 study patients, 12 (14.8%) were deemed to have osteoporosis, defined by a percentage of YAM <70, with a dominance of females over males (66.7% vs 17.4%; P < 0.001). The median body weight, hemoglobin concentration, and serum alkaline phosphatase (ALP) level of the patients with osteoporosis was significantly lower than in those with a percentage of YAM ≥70 group (39.6 kg vs 53.1 kg, P < 0.001; 10.9 mg/dL vs 12.5 mg/dL, P = 0.010; 210 U/L vs 251 U/L, P = 0.002). Further analyses revealed a significant positive correlation between body weight and percentage of YAM (r = 0.441, P < 0.001). Despite the administration of bisphosphonates in these patients during this study, one acquired a bone fracture. Conclusion Osteoporosis was found in 14.8% of postoperative gastric cancer patients, with female gender, low body weight, and low ALP proposed as risk factors for osteoporosis and thus future bone fracture.

Abstract
Recent developments in diagnostic technology, accumulated clinical effort and established evidence have boosted early detection and drastically improved early and long-term outcomes of gastric cancer. However, gastric cancer continues to be one of the most aggressive and life-threatening malignancies among all cancers and is a global health problem. Between January 2017 and December 2018, various fascinating reports of managements and research were published, including the new 15th Japanese Classification of Gastric Carcinoma reflecting the 8th American Joint Committee on Cancer/Union for International Cancer Control (AJCC/UICC) tumor, node and metastasis (TNM) classification (October 2017) and the new Gastric Cancer Treatment Guidelines version 5 (January 2018). Moreover, pivotal molecular features of gastric cancer were clarified by the worldwide cancer genome project, and various treatment targets and biomarkers such as circulating DNAs and microRNAs were detected. Novel treatment options using programmed cell death protein 1 immune checkpoint inhibitors have been started. In this review, we summarize the recent topics of classification, guidelines, and clinical and basic research in order to bring new insights to gastric cancer treatment.

[PMID: 31254731 DOI: 10.1016/j.bone.2019.06.014] [Citation(s) in RCA: 16] [Impact Index Per Article: 3.2] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/05/2019] [Revised: 06/02/2019] [Accepted: 06/17/2019] [Indexed: 12/24/2022]
Abstract
PURPOSE Many studies have reported that patients with a history of gastrectomy (gastrectomized patients) have lower areal bone mineral density (aBMD) and higher fracture risk than those without. However, population-based studies on this topic are scarce, and little is known regarding the bone metabolic status of gastrectomized patients in the long-term. This study aimed to clarify the association of gastrectomy with aBMD, bone metabolism markers, and fracture risk in community-dwelling elderly Japanese men. METHODS A total of 1992 men aged ≥65 years completed baseline measurements including aBMD at the spine and hip, serum levels of intact parathyroid hormone (PTH), intact osteocalcin (OC), tartrate-resistant acid phosphatase isoenzyme 5b (TRACP5b), and undercarboxylated OC (ucOC), and an interview regarding past medical history including gastrectomy. Osteoporotic fractures (OPFs) that occurred during the 5-year follow-up period were determined through structured interviews. RESULTS After excluding participants with type 1 diabetes mellitus and those with missing values, 1985 men, including 132 gastrectomized men, were analyzed. Gastrectomized men had significantly higher PTH, TRACP5b, and ucOC levels, and lower aBMD, than non-gastrectomized men. Gastrectomy was associated with a significantly higher risk of OPF after adjusting for confounding variables (hazard ratio (HR): 2.55, 95% confidence interval (CI): 1.17, 5.55), and the risk was no longer significant when further adjusted for PTH and aBMD. Even in this model, however, increase in OPF risk was significant in gastrectomized men who survived 20 years or more after the surgery (HR: 3.56, 95% CI: 1.33, 9.52). CONCLUSIONS History of gastrectomy was associated with elevated bone resorption, decreased aBMD, and increased fracture risk in community-dwelling elderly Japanese men. This increase in fracture risk was more prominent long after gastrectomy.

Abstract
Background: This paper purports to use a meta-analysis to compare the postoperative quality of life (QoL) and nutritional status of between Roux-en-Y (R-Y) and Billroth-I (B-I) reconstruction after distal gastrectomy.Methods: For this study, the following databases were searched for articles published from inception until December 2018: PubMed, Web of Science, EBSCO, and Cochrane library.Results: A total of 13 eligible studies, covering 3645 patients, were selected for a meta-analysis. The analysis showed that compared with B-I group in term of short-term outcomes, patients undergoing R-Y reconstruction did not only have significantly better physiological function (P = 0.02), but had significantly less pain (P = 0.04). In the long-term outcomes, the dyspnea and constipation in the B-I group were worse than that in the R-Y group (P = 0.004; P = 0.04, respectively). Patients in the B-I group had higher cholesterol than those in the R-Y group at 5 years postoperatively (P = 0.003). There were no significant differences in termof other nutritional indicators including total protein, cholesterol, albumin, hemoglobin and weight in short-term outcomes.Conclusions: The final conclusion was that R-Y may be superior to the B-I reconstruction in some aspects of QoL. Besides, R-Y reconstruction could reduce the patient's cholesterol level for a long time. For the short-term outcomes, there were no significant differences in other common nutritional indicators.

Abstract
For benign and borderline tumors in the pancreatic neck and proximal body, laparoscopic spleen-preserving distal pancreatectomy (LSPDP) and laparoscopic central pancreatectomy (LCP) are alternative surgical procedures. Choosing between LSPDP and LCP is difficult. This retrospective cohort study was looking forward to provide evidence for clinical decision.A total of 59 patients undergoing LSPDP (Kimura procedure) and LCP between June 2013 and March 2017 were selected. The clinical outcomes of patients were compared by χ test or Fisher exact test and Student t test.This study included 36 patients in LSPDP group, and 23 patients in LCP group. The overall complications incidence in LCP group was significantly higher than LSPDP group (35 vs 6%, P = .004), and the postoperative pancreatic fistula (POPF) (grade B and C) rate and abdominal infection rate in LCP group were still significantly higher than LSPDP group (POPF 22 vs 3%, P = .019; abdominal infection 35 vs 3%, P = .001, respectively). The length of resected pancreas was significantly longer in LSPDP group (9.8 ± 2.0 vs 5.3 ± 1.1 cm, P = .007). The median follow-up was 39 months (range 12-57 months). No patient was confronted by tumor recurrence. The proportion of postoperative pancreatin and insulin treatment in LCP group were similar to LSPDP group (9 vs 17%, P = .383; 0 vs 3%, P = 1.000, respectively).For patients with poor general condition, the safety of LCP needs to be taken seriously; in some ways, LSPDP may be more secure, physiological, and easier operation for tumor located in pancreatic neck and proximal body.
