[A Case of Small Intestinal Metastasis from Lung Cancer].

An 88-year-old man underwent thoracoscopic lower lobectomy for left lung cancer at the age of 87. Ten months later, he was examined closely for abdominal distention, frequent constipation, and anemia with a decreased Hb of 6.1 g/dL.

[A Case of Complete Remission in a Patient with Synchronous Double Cancers of the Breast and Lung].

The patient is a 74-year-old woman. She had breast cancer(invasive ductal carcinoma, ER[+], PgR[+], HER2[-], Ki-67: 30-40%)and primary right lung cancer with lumbar metastasis, which led to the diagnosis synchronous double cancers of the breast and the lung. We decided to precede surgery for lung cancer because breast cancer was indicated hormonal receptor positive.

Nonresponder Considerations for Romosozumab Treatment.

Romosozumab can increase bone mineral density (BMD) in patients with osteoporosis, but some patients do not respond to it. This study aimed to identify risk factors for being a nonresponder to romosozumab treatment. This retrospective observational study included 92 patients.

[A Case of Liver Metastasis of Colorectal Cancer Successfully Treated with Hepatic Arterial Infusion Chemotherapy after Systemic Chemotherapy Was Difficult to Administer].

The patient underwent partial sigmoid colon resection for sigmoid colon cancer with hyper CEA blood(1,110.6 ng/mL) and concurrent liver metastases mostly in the right lobe of the liver, followed by systemic chemotherapy(SOX plus BEV). Seven courses of chemotherapy resulted in PR on imaging, and CEA was reduced to 5.

[A Case of Rectal GIST under Long-Term Follow-Up with Oral Imatinib].

The patient was a 79-year-old man with complaints of defecation difficulties and constipation. CT scan showed a 7.5 cm diameter mass in the lower rectum, and biopsy revealed GIST.

[The Short-Term and Long-Term Outcomes of Laparoscopic and Open Distal Gastrectomy].

We compared laparoscopic gastrectomy and open gastrectomy for the early gastric cancer. Laparoscopic surgery was comparable to laparotomy in terms of operation time and number of lymph node dissections, significantly less bleeding volume, postoperative hospital stay, and lower postoperative complication rate. As a result of E-PASS, surgical invasion was significantly low and the overall risk score was also significantly low.

Risk Factors for Esophagojejunal Anastomotic Leakage in Gastric Cancer Patients after Total Gastrectomy.

Background: Leakage at the esophagojejunal anastomosis site is an important postoperative complication of total gastrectomy. We analyzed our surgical cases to determine the risk factors for esophagojejunal anastomotic leakage.

Methods: This study included 309 patients who underwent total gastrectomy and esophagojejunal anastomosis.

The Prognostic Nutritional Index as a Predictor of Gastric Cancer Progression and Recurrence.

Background: Gastric cancer can recur soon after treatment. We evaluated the prognostic nutritional index (PNI), a predictor of postoperative complications, and examined the association of PNI with progression and recurrence of gastric cancer.

Methods: We retrospectively investigated data from 697 patients who had undergone surgery for gastric carcinoma (excluding those with stage IV disease) and analyzed associations of age, sex, performance status (PS), American Society of Anesthesiologists (ASA) classification, diabetes, depth of main tumor (T), lymph node metastasis, postoperative complications, recurrence, and survival with PNI.

Effect of the duration of previous osteoporosis treatment on the effect of romosozumab treatment.

Unlabelled: The effect of romosozumab is affected by previous osteoporosis treatment. Here we showed that the duration of the previous treatment just before romosozumab affects the therapeutic effect of romosozumab. Using denosumab and oral bisphosphonates for more than 1 year attenuates the effect of romosozumab.

[A Case of Hyaline Vascular-Type Castleman's Disease].

The patient was a 29-year-old female with a chief complaint of transient right-sided abdominal pain. A CT scan revealed homogenously contrasted tumor of 4 cm in diameter with smooth margins and clear borders in the lower part of the pancreatic head. The tumor was contrast-enhanced on MRI and stained on abdominal angiography using the proximal branch of the right colonic artery as a feeding vessel.

The Influences of Obesity in Laparoscopic and Open Distal Gastrectomy for Patients with Early Gastric Cancer.

Background: A recent increase in the number of surgeries performed on obese patents has raised several issues. In this study, we examined the effects of obesity on laparoscopic and open distal gastrectomy.

Methods: A total of 262 patients with gastric cancer (cStage I) who underwent distal gastrectomy were classified into open distal gastrectomy (ODG) (145 patients) and laparoscopic distal gastrectomy (LDG) (117 patients) groups.

Early clinical effects, safety, and predictors of the effects of romosozumab treatment in osteoporosis patients: one-year study.

Unlabelled: Romosozumab is an effective treatment for spine osteoporosis because it reduces the incidence of new fractures and significantly increases the percent change in the spine BMD at 12 months. The percent change in the spine BMD is higher in patients not previously treated with other anti-osteoporosis medications.

Introduction: Romosozumab appeared as a new osteoporosis medication in Japan in 2019.

[Comparison of Laparoscopic Gastrectomy and Open Gastrectomy Outcomes in the Elderly].

In this study, we compared the outcomes of laparoscopic gastrectomy and open gastrectomy in the elderly. Laparoscopic surgery was comparable to laparotomy in terms of the operation time and number of lymph node dissections and was significantly associated with less bleeding volume, duration of postoperative hospital stay, and a lower postoperative complication rate. Surgical invasion and overall risk scores were significantly low as assessed by the Estimation of Physiologic Ability and Surgical Stress(E-PASS)system.

[A Case of Colon Cancer with Synchronous Multiple Metastases Successfully Treated with Combined Chemotherapy].

A 68-year-old man having a descending colon cancer with multiple metastases of up to 9.5 cm in the right lobe of the liver(T3, N0, M1a)underwent laparoscopic colon resection for anemia control. Chemotherapy with mFOLFOX6 plus Bmab was administered postoperatively.

Early clinical effects, safety, and appropriate selection of bone markers in romosozumab treatment for osteoporosis patients: a 6-month study.

Unlabelled: Our 6-month study showed the usefulness of romosozumab for preventing fractures and its safety. It was effective in patients with low baseline spine BMD, high TRACP-5b, and high iP1NP. Percent change from baseline of TRACP-5b and iP1NP after 1 month correlated with that from baseline of BMD after four to 6-month treatment.

[Study on Gastric Cancer Surgery in an Aged Society].

We examined the occurrence of complications following gastric cancer surgery in the elderly and its influence on the prognosis of reduction surgery.The study included 805 surgical cases of gastric cancer; elderly, middle-aged, and young patients were examined.In the elderly patients, there was a tendency to undergo reduction surgery.

[Stage Ⅳ Breast Cancer with Difficulty in Initiating Chemotherapy-A Case Report].

We report a case of breast cancer(T4b[skin], N1, M1[lung], ER-, PR-, HER2 3+)in a 63-year-old woman with liver dysfunction of unknown cause(T-Bil 3.6mg/dL, ALP 3,483 U/L, AST 214 U/L, ALT 320 U/L, g / -GTP 1,943 U/L). Further- more, serum CA19-9(4,670 U/mL)and HbA1c(8.

[A Case of Unresectable Sigmoid Colon Cancer with Peritoneal Dissemination Treated with Chemotherapy after an Unintended Emergency Jejunostomy Formation].

A 33-year-old man was diagnosed with bowel obstruction due to advanced sigmoid colon cancer and underwent an emergency laparotomy. The sigmoid colon cancer turned out to be unresectable because of firm invasion to the retroperitoneum with severe adhesions and diffuse dissemination. Therefore, unplanned jejunostomy was performed, which was complicated by high-output stoma and short bowel syndrome.

Hypoalbuminemia differently affects the serum bone turnover markers in hemodialysis patients.

Renal osteodystrophy (ROD) represents bone disorders related to chronic kidney disease (CKD) and several bone biomarkers are used clinically to predict ROD in CKD and hemodialysis (HD) patients. Serum albumin associates with inflammation other than nutritional status in these patients. Chronic inflammation is proved to relate with bone loss, however, the influence of hypoalbuminemia on bone biomarkers is still unclear.

[A Case of Advanced Rectal Cancer in Which Long-Term Disease-Free Survival Was Achieved by Multidisciplinary Therapy].

The is a case involving a 55-year-old man with advanced rectal cancer(type 3). MRI showed urinary tract and regional lymph node metastases without distant metastasis. The tumor was reduced(PR)after neoadjuvant chemotherapy(mFOL FOX6 plus Bmab, 4 courses).

[A Case of Successful Treatment with Gemcitabine plus Nab-Paclitaxel Therapy for Nonresected Pancreatic Body Cancer(Stage IVb)].

A 61-year-old woman was introduced for consultation with a chief complaint of frequent vomiting. CT revealed a pancreatic body cancer approximately 40mm in size; an invading stenosis from the horizontal part of the duodenum to the jejunum, superior mesenteric artery, and portal vein, splenic vein obstruction, lymphadenopathy, and some ascitic fluid. We diagnosed a passage disorder due to the invasive stenosis from the horizontal part of the duodenum of the pancreatic body cancer to the jejunum, and subsequently performed a duodenum and jejunum bypass operation.

The Primary Result of Prospective Randomized Multicenter Trial of New Spray-Type Bio-absorbable Adhesion Barrier System (TCD-11091) Against Postoperative Adhesion Formation.

Background: Postoperative adhesions are the major cause of postoperative complications including intestinal obstruction, infertility, and chronic pelvic pain. In order to reduce postoperative adhesions, Terumo Corporation (Tokyo, Japan) has developed an adhesion barrier system (TCD-11091) which is easy to use at the treatment site in various surgical procedures including laparoscopic surgeries. We conducted a prospective randomized single-blind study in patients who underwent laparotomy with ileostomy.
