ABSTRACT
BACKGROUND: We previously reported the response rate of a phase II OGSG1602 study on panitumumab in chemotherapy-naive frail or elderly patients with RAS wild-type unresectable colorectal cancer (CRC) [Terazawa T, Kato T, Goto M, et al. Oncologist. 2021;26(1):17]. Herein, we report a survival analysis. METHODS: Patients aged ≥65 years and considered unsuitable for intensive chemotherapy or aged ≥76 years were enrolled. Primary tumors located from the cecum to the transverse colon were considered right-sided tumors (RSTs); those located from the splenic flexure to the rectum were considered left-sided tumors (LSTs). RESULTS: Among the 36 enrolled patients, 34 were included in the efficacy analysis, with 26 and 8 having LSTs and RSTs, respectively. The median progression-free survival (PFS) and overall survival (OS) were 6.0 [95% CI, 5.4-10.0] and 17.5 months (95% CI, 13.8-24.3), respectively. Although no significant differences existed in PFS between patients with LST and RST {6.6 (95% CI, 5.4-11.5) vs. 4.9 months [95% CI, 1.9-not available (NA), P = .120]}, there were significant differences in OS [19.3 (95% CI, 14.2-NA) vs.12.3 months (95% CI, 9.9-NA), P = .043]. CONCLUSION: Panitumumab showed favorable OS in frail or elderly patients with RAS wild-type CRC and no prior exposure to chemotherapy. Panitumumab may be optimal for patients with LSTs (UMIN Clinical Trials Registry Number UMIN000024528).

BACKGROUND: Biliary atresia (BA) is among the commonest indications for liver transplantation (LT) in children. We examined whether serum matrix metalloproteinase-7 (MMP-7) is useful for diagnosis of BA in Japanese infants, and whether serum MMP-7 concentrations before and after Kasai portoenterostomy (KP) predicted LT within a year. METHODS: Subjects under 6 months old at eight pediatric centers in Japan were enrolled retrospectively, including patients with cholestasis and normal controls (NC) without liver disease. Patients with cholestasis were divided into groups representing BA versus cholestasis from other causes (non-BA). Serum samples were collected from patients with BA at diagnosis and 1 and 4 weeks after KP, as well as from non-BA and NC. RESULTS: Serum MMP-7 concentrations were significantly higher in BA at diagnosis (median, 89.1 ng/ml) than in non-BA (11.0; p < 0.001) or NC (10.3; p < 0.001). Receiver operating characteristic (ROC) analysis of MMP-7 for BA versus non-BA yielded an area under the ROC curve of 0.99 (95% confidence interval, 0.96-1.00). An optimal cut-off value of 18.6 ng/ml for serum MMP-7 in diagnosing BA demonstrated sensitivity and specificity of 100% and 90%, respectively. Serum MMP-7 before and 1 week and 4 weeks after KP did not differ significantly between BA requiring only KP and BA requiring LT after KP. CONCLUSION: Serum MMP-7 is a useful marker for diagnosis of BA in Japanese infants, but it could not predict LT within a year.
ABSTRACT
BACKGROUND: Reports of zinc and selenium deficiencies accompanying inflammatory bowel disease (IBD) mostly have originated from Western countries and concerned adult patients. Whether Japanese children with IBD have similar deficiencies remained unclear. AIM: We aimed to elucidate differences in serum zinc and selenium concentrations in Japanese children between types of IBD. METHODS: Children under 17 years old undergoing care at 12 Japanese pediatric centers were retrospectively enrolled between November 2016 and February 2018 to 3 groups representing Crohn's disease (CD), ulcerative colitis (UC), and normal controls (NC) with irritable bowel syndrome or no illnesses. Serum zinc and selenium were measured by atomic absorption spectrophotometry. Zinc and selenium deficiencies were defined by serum concentrations < 70 µg/dL and < 9.5 µg/dL, respectively. RESULTS: Subjects included 98 patients with CD (median age, 13 years), 118 with UC (11 years), and 43 NC (11 years). Serum zinc and selenium were significantly lower in CD (median, 64 and 12.6 µg/dL respectively) than in UC (69 and 14.6; P < 0.05 and P < 0.001) or NC (77 and 15.7; P < 0.01 and P < 0.001). Zinc deficiency was significantly more prevalent in CD (60.2%) than in NC (37.2%; P < 0.05), but not than in UC (51.7%; P = 0.22). Selenium deficiency was significantly more prevalent in CD (15.3%) than in UC (5.9%; P < 0.05) or NC (0%; P < 0.01). CONCLUSIONS: In Japanese children under 17 years old, serum zinc and selenium were significantly lower in CD than in UC or NC. Zinc and selenium should be monitored, and supplemented when deficient, in children with IBD, especially CD.

LESSONS LEARNED: The 3-year disease-free survival rate of the twice-daily regimen was not inferior to that of the conventional three-times-daily regimen, and the twice-daily regimen did not lead to an increase in adverse events. The effectiveness of the twice-daily regimen highlights an increased number of treatment options for patients. This will facilitate personalized medicine, particularly for elderly or frail patients who may experience more severe side effects from the combination therapy. BACKGROUND: Tegafur-uracil (UFT)/leucovorin calcium (LV) is an adjuvant chemotherapy treatment for colorectal cancer. We conducted a multicenter randomized trial to assess the noninferiority of a twice-daily compared with a three-times-daily UFT/LV regimen for stage II/III colorectal cancer in an adjuvant setting. METHODS: Patients were randomly assigned to group A (three doses of UFT [300 mg/m2 per day]/LV [75 mg per day]) or B (two doses of UFT [300 mg/m2 per day]/LV [50 mg per day]). The primary endpoint was 3-year disease-free survival. RESULTS: In total, 386 patients were enrolled between July 28, 2011, and September 27, 2013. The 3-year disease-free survival rates of group A (n = 194) and B (n = 192) were 79.4% and 81.4% (95% confidence interval, 72.6-84.4-74.5-85.9), respectively. The most common grade 3/4 adverse events in group A and B were diarrhea (3.9% vs. 7.3%), neutropenia (2.9% vs. 1.6%), increase in aspartate aminotransferase (4.0% vs. 3.9%), increase in alanine aminotransferase (6.2% vs. 6.8%), nausea (1.7% vs. 3.4%), and fatigue (1.1% vs. 2.3%). CONCLUSION: Group B outcomes were not inferior to group A outcomes, and adverse events did not increase.

LESSONS LEARNED: Panitumumab monotherapy showed favorable efficacy and feasibility in the treatment of frail or elderly patients with RAS wild-type unresectable colorectal cancer. It is especially effective for left-sided tumors; therefore, panitumumab as first-line treatment could be an additional therapeutic option for frail elderly patients, particularly in those who are unsuitable for upfront oxaliplatin-based or irinotecan-based combination regimens. BACKGROUND: First-line panitumumab monotherapy is expected to be well tolerated and improve survival in patients ineligible for intensive chemotherapy. However, its safety and efficacy in chemotherapy-naïve frail or elderly patients with unresectable RAS wild-type (WT) colorectal cancer (CRC) have not been studied. The aim of this phase II trial was to evaluate the efficacy and safety of panitumumab as first-line treatment. METHODS: We conducted a multicenter phase II study on patients aged ≥76 years or ≥65 years considered unsuitable for intensive chemotherapy. Panitumumab 6 mg/kg of intravenous infusion was administered every 2 weeks. The primary endpoint was disease control rate (DCR). Secondary endpoints included progression-free survival (PFS), overall survival (OS), response rate (RR), time to treatment failure (TTF), and incidence of grade 3 or 4 toxicities. RESULTS: Thirty-six patients (median age: 81 [range, 67-88] years) were enrolled between February 2017 and August 2018. Two patients were excluded from the analysis of efficacy: one from lack of image examination at baseline and the other from lack of a measurable lesion. Thirty-three (91.6%) patients had a performance status (PS) of 0 or 1, whereas two (5.6%) patients and one (2.8%) patient had a PS of 2 and 3, respectively. Twenty-eight patients (77.8%) had left-sided CRC, whereas eight (22.2%) had right-sided CRC. The RR was 50.0% (95% confidence interval [CI], 32.4-67.6), including three patients (8.8%) who had complete responses. A total of 26.5% had stable diseases, resulting in a DCR of 76.5% (90% CI, 61.5-87.7). The RR of patients with left- and right-sided tumors was 65.4% (95% CI, 44.3-82.8) and 0.0% (95% CI, 0.0-36.9), respectively. Major grade 3 or 4 nonhematologic toxicities were rash (n = 6, 16.7%), hypomagnesemia (n = 4, 11.1%), fatigue (n = 3, 8.3%), paronychia (n = 2, 5.6%), and hyponatremia (n = 2, 5.6%). The only grade 3 hematologic toxicity was neutropenia (n = 1, 2.8%). CONCLUSION: Panitumumab monotherapy showed favorable efficacy and feasibility in frail or elderly patients with RAS WT unresectable CRC. Survival analysis including OS, PFS, and TTF is currently in progress.

BACKGROUND AND AIM: Serologic markers such as myeloperoxidase (MPO) antineutrophil cytoplasmic antibodies (ANCA) (MPO-ANCA) have been used to screen patients for ulcerative colitis (UC). However, MPO-ANCA shows limited accuracy in Asians. Proteinase 3 ANCA (PR3-ANCA) has performed better at UC diagnosis in Japanese adults than MPO-ANCA. The present study aimed to evaluate usefulness of PR3-ANCA for diagnosis of UC in Japanese pediatric practice. METHODS: Patients under 17 years old undergoing assessment at 12 Japanese pediatric centers between November 2016 and February 2018 were prospectively enrolled and divided into groups with UC, Crohn's disease (CD), intestinal disease control (IC), and healthy control (HC). Serum PR3-ANCA and MPO-ANCA were analyzed using chemiluminescence enzyme immunoassay kits. RESULTS: Sera from 367 patients (148 with UC at a median age of 12 years; 120 with CD, 13 years; 56 with IC, 10.5 years; and 43 with HC, 10 years) were examined. Median PR3-ANCA values in UC (1.6 U/mL) were greater than in CD (0.2; P < 0.001), IC (0.15; P < 0.001), and HC (0.1; P < 0.001). In receiver operating characteristic curve analyses, the area under the curve for PR3-ANCA was 0.79, significantly greater than for MPO-ANCA (0.58; P < 0.001). Using a cut-off value of 0.8 U/mL determined from the receiver operating characteristic analyses, PR3-ANCA showed significantly greater sensitivity (64.9%) than MPO-ANCA (cut-off, 0.2 U/mL; sensitivity, 19.6%; P < 0.001) and good specificity (83.6%). CONCLUSIONS: In Japanese children and adolescents, PR3-ANCA performed better as a serologic marker for diagnosis of UC than MPO-ANCA. To our knowledge, this is the first report of such a comparison.

A patient was 70-year-old female. Because unknown fever following operation of left knee in December 20XX-1, abdominal simple CT was performed, diagnosed as cholecystitis and liver abscesses. However, her unknown fever did not improve with antibiotics therapy. Abdominal enhanced CT and MRI revealed to gallbladder cancer with liver invasion and metastases. These lesions were relatively localized in liver S4a/S5 and gallbladder, hepatoduodenal mesentery. Because unknown fever was exhausting, cholecystectomy, S4a+S5 hepatectomy with extrahepatic bile duct resection and lymph node dissemination were performed in January 20XX+1. In these pathological findings, there were moderate to poorly differentiated adenocarcinoma with squamous cell differentiation in almost area of gallbladder, diagnosed as adeno-squamous carcinoma with liver invasion and metastasis(pT3a[SI][H-inf], int, INF-ß, ly1, v3, pn1, pN1, pM1, pStage â £B). One months after operation, abdominal CT revealed multiple liver metastatic recurrences. She died 7 months after operation. Although gallbladder adeno-squamous carcinoma has a poor prognosis, these many cases had a tendency to local infiltration accompanied with tumor fever. If curative resection might be obtained and the symptoms might be improved, aggressive resection should be performed.

A 69-year-old female underwent a mesh repair for an abdominal incisional hernia 4 years previously in our hospital. She visited local hospital for abdominal pain and fever. Abdominal CT showed a localizes abscess formation above the mesh, then she was taken to our hospital. We suspected mesh infection and performed emergent mesh removal. After the operation, we examined for her anemia. Her colonoscopy and CT findings pointed to transverse colon cancer. We performed right hemicolectomy, and final diagnosis was transverse colon cancer pT4aN0M0, pStage â ¡b. She underwent adjuvant chemotherapy, and 9 months after surgery, no recurrence was found.

BACKGROUND: Chemotherapy in relapsed colorectal cancer patients treated with oxaliplatin as adjuvant chemotherapy is under debate. REACT study aimed to investigate the efficacy of reintroducing modified FOLFOX6 (mFOLFOX6) or CAPOX with or without bevacizumab in recurrent colorectal cancer patients after oxaliplatin adjuvant chemotherapy. METHODS: Patients that participated in this trial had a medical history of adjuvant chemotherapy, including oxaliplatin with a cumulative dose greater than 400 mg/m2, and recurrence that was diagnosed more six months post adjuvant chemotherapy. Primary endpoints were response rate (RR) and disease control rate (DCR), while key secondary endpoints were time to treatment failure (TTF), progression-free survival (PFS), overall survival (OS), and safety. RESULTS: A total of 31 patients were enrolled between October 2012 and October 2016. Of the 29 eligible patients, 7 received mFOLFOX6 and 22 received CAPOX. The RR was 62.1% (95% confidence interval 42.3-79.3) and the DCR was 82.8% (95% confidence interval 64.2-94.2). The RR for oxaliplatin-free interval was 100.0% in months 6-12 and 56.0% after 12 months. Median TTF, PFS, and OS were 6.3, 10.8, and 28.7 months, respectively. Grade 3 or worse peripheral sensory neuropathy developed in 6.5%. Allergic reactions occurred in 12.9% of the patients, with one (3.2%) grade 3 episode. There were no other severe treatment-related adverse events. CONCLUSION: Reintroduction of oxaliplatin was feasible and achieved high RR or DCR in patients after more than 6 months post oxaliplatin adjuvant chemotherapy.

A 50-year-old woman was admitted to our hospital due to intermittent epigastric pain and vomiting for 2 months. Contrast enhanced CT scan showed stenosis in the upper jejunum. She was diagnosed with small intestinal ileus. A small enteroscopy revealed a peripheral type 2 lesion in the upper jejunum, approximately 10 cm from the Treitz's ligament. Upon biopsy, she was diagnosed with a well-differentiated adenocarcinoma. A laparoscope-assisted extracorporeal operation was performed due to the ease of raising the umbilical wound. Swollen lymph nodes were found in the mesentery. A surgical margin of 5 cm on the oral side and 20 cm on the anal side was secured. We performed partial resection of the small intestine, including the mesentery with the enlarged lymph nodes. The histopathological diagnosis was a Type 2, 3×2 cm, tub2, pT4aN1aM0, pStage â ¢b small intestinal cancer. Due to the development of small intestinal ileus, the small bowel cancer was diagnosed preoperatively. Hence, it was slightly we will report including the literature consideration of.

A man in his 60s with a large Type 3 gastric cancer presented with the chief complaint of epicardial discomfort. We decided to perform laparoscopy. The patient was diagnosed with cT4aN2M1(CY1), cStage â £ disease and was treated with XP(capecitabine plus cisplatin[CDDP])plus trastuzumab(HER). After chemotherapy, CY0 was confirmed using laparoscopy. The patient underwent total gastrectomy and D2 lymph node dissection. Histopathological examination revealed ypT4aN3M0, ypStage â ¢C disease. Therefore, adjuvant treatment with XP plus HER was continued. Four months after surgery, liver, lung, and # 16b1latLN metastases were observed on CT. The metastatic foci were observed even after 3 courses of ramucirumab plus paclitaxel. Nivolumab was administered as the third-line treatment; after 3 courses, the liver metastasis increased markedly. Hence, our final diagnosis was hyperprogressive disease(HPD).

The patient was a 79-year-old woman. In January 20XX, upper gastrointestinal endoscopy revealed a duodenal tumor with bleeding and ulceration. This tumor was diagnosed as a duodenal neuroendocrine tumor(NET)based on biopsy findings. In March 20XX, the patient underwent pancreatoduodenectomy with lymph node dissemination. Based on these pathological findings, the tumor was diagnosed as a duodenal NET(G2)with a lymph node metastasis(T2, N1, M0, Stage â ¢). Twenty months after the operation, abdominal CT revealed multiple liver metastases(S4, S7, and S8). After this recurrence, she underwent the subcutaneous somatostatin analogue injection therapy every 28 days, and transarterial chemoembolization( TACE)when these recurrent tumors showed remarkable regrowth, once a year, accounting for her age. She has maintained good disease control for 5 years.

A 78-year-old woman had undergone subtotal stomach-preserving pancreatoduodenectomy for acinar cell carcinoma (ACC)of the pancreatic head approximately 2 years before presentation, and the pathological diagnosis had been pT2pN0pM0, fStageâ B(JPS 7th). Adjuvant chemotherapy was discontinued after 3 months because of side effects. Contrast- enhanced CT and PET-CT 2 years postoperatively revealed a tumor measuring 2 cm with a high concentration of FDG in the minor curvature of the stomach. During laparotomy, a 3 cm large lymph node was palpated in the minor curvature of the stomach, and a small lymph node was found adjacently. We diagnosed the patient with multiple lymph node recurrences and performed gastric lymph node dissection of the minor curvature. The pathological diagnosis was a single 2 cm large ACC lymph node metastasis. The patient did not consent to postoperative adjuvant chemotherapy and showed no recurrence for 1 year and 7 months postoperatively. Pancreatic ACC is a rare pancreatic tumor, and its clinicopathologic features are still largely unknown. In recent years, there have been reports of active resection or long-term survival with anti-cancer drug treatment even in recurrent cases, such as the present case. However, the indication and method of anti-cancer treatment are unclear and might need the accumulation of many more cases.

A 60's woman was admitted to our hospital because of palpitations that occurred with exertion. Coronary angiography computed tomography(CT)of suspected angina detected a tumor in the pancreatic head region. Abdominal CT showed a poorly enhanced 40×32 mm solid tumor in the hepatoduodenal ligament that contained a fatty component and calcification. During surgery, the tumor was located in the hepatoduodenal ligament, adhered to the pancreatic head, common hepatic artery, gastroduodenal artery, portal vein and common bile duct. However, the tumor was resected by preserving them. The tumor contained stratified squamous epithelium, a sebaceous gland, nerve, a pancreatic gland, and an adrenal gland. The histological diagnosis was a mature cystic teratoma. The patient showed no recurrence in 2 years and 10 months post-surgery. Mature teratomas in the hepatoduodenal ligament are extremely rare. Some reports showed that combined resection was performed when the tumor was in contact with the common bile duct, portal vein, and arteries. However, in our case, the tumor was removed relatively safely without combined resection.

An 84-year-old woman with a chief complaint of right lower abdominal pain was admitted to our hospital in November 20XX. Abdominal CT scan revealed a 9.6×4.1 cm diameter low density area proximal to the 13 mm diameter appendix, which led to perforated appendicitis with a huge abscess. The patient underwent an open appendectomy with partial cecum resection. The appendix was found to be twisted by 540°. The pathological diagnosis was low-grade appendiceal mucinous neoplasm(LAMN). Recent research has found that the use of laparoscopic surgery for the treatment of LAMN has been increasing. Appropriate surgical intervention should be considered for LAMN because it is a borderline malignancy. Careful treatment with laparoscopic surgery might be considered as one of the treatment options for LAMN. We hope to accumulate more cases of LAMN to confirm our results.

In December 20XX-1, abdominal enhanced CT of a 73-year-old female patient showed a 28mm-in-diameter pancreatic tail cancer with splenic venous invasion. She underwent neoadjuvant GEM/TS-1 combination chemotherapy but abandoned this chemotherapy due to melena and exanthema. She underwent a distal pancreatectomy with lymph node dissemination. In these pathological findings, the tumor was diagnosed as a pancreatic tail cancer with splenic venous invasion(T3, N0, M0, Stage â ¡A). She underwent adjuvant GEM chemotherapy, but she abandoned this chemotherapy due to exanthema and was managed with observation. In September 20XX, she had a postoperative bowel obstruction and was treated with natural light. However, she had a postoperative bowel obstruction again in July, 20XX+1. Fluoroscopic images revealed stenosis in the intestine located 170 cm from the nasal cavity. She underwent open surgery to manage the bowel obstruction. There was a peritoneal tumor with adhesion to each intestine serosa in 3 areas located 80 cm, 100 cm, and 150 cm from the Treitz ligament. Therefore, she underwent a small intestine resection and anastomosis 70 cm to 110 cm from the Treitz ligament. Pathological findings showed that there was a 3mm-in-diameter adenocarcinoma in this peritoneal tumor. In these findings, this final diagnosis was an adhesive intestinal obstruction caused by peritoneal metastasis. Curative resection for single peritoneal recurrent metastasis might be useful for prognosis prolongation.

OBJECTIVE: To clarify clinical and genetic features of Japanese children with congenital chloride diarrhea (CCD). STUDY DESIGN: This was a multi-institutional, retrospective survey of 616 pediatric centers in Japan with identified patients with CCD between 2014 and 2018. Mutations involving SLC26A3 were detected by Sanger sequencing. RESULTS: Thirteen patients met all entry criteria including mutations in SLC26A3, and 14 patients satisfied clinical diagnostic criteria. Homozygous or compound heterozygous mutations in SLC26A3, including 6 novel mutations, were identified in 13 of these 14 patients (93%). The most common (detected in 7 of 13) was c.2063-1g>t. Median age at diagnosis was 1 day. Nine of the patients meeting all criteria were diagnosed as neonates (69%). Median follow-up duration was 10 years. When studied, 8 patients had <5 stools daily (62%), and all had fewer than in infancy. Only 1 patient had nephrocalcinosis, and 3 (23%) had mild chronic kidney disease. Neurodevelopment was generally good; only 1 patient required special education. Five patients (38%) received long-term sodium, potassium, and chloride supplementation. CONCLUSIONS: Early fetal ultrasound diagnosis and prompt long-term sodium, potassium, and chloride supplementation were common management features. Genetic analysis of SLC26A3 provided definitive diagnosis of CCD. In contrast with previously reported localities, c.2063-1g>t might be a founder mutation in East Asia.

BACKGROUND: Hermansky-Pudlak syndrome (HPS) is a rare, genetically heterogeneous disorder that manifests oculocutaneous albinism together with bleeding diatheses that reflect a platelet storage pool deficiency. Ten genetic subtypes of this autosomal recessive condition have been described to date. Some patients with Hermansky-Pudlak syndrome type 1, 4, or 6 develop Crohn's-like inflammatory bowel disease at any age including early childhood, but most often in adolescence or young adulthood. Here we report infantile-onset of inflammatory bowel disease in a patient with Hermansky-Pudlak syndrome type 1 who responded to infliximab. CASE PRESENTATION: A Japanese boy, the second child of non-consanguineous healthy parents, was born with chalky white skin, silvery-white hair, and gray eyes, representing oculocutaneous albinism. He developed frequent diarrhea and fever accompanied by weight loss at 6 months, and was diagnosed with Crohn's-like inflammatory bowel disease based on the endoscopic finding of longitudinal ulcerations in the colon and the histopathologic finding of nonspecific chronic inflammation without granulomas at the age of 11 months. Treatment with an elemental diet, salazosulfapyridine, and corticosteroids failed to improve clinical or laboratory abnormalities, and the diarrhea became bloody. At 13 months he began treatment with infliximab, which produced marked improvement followed by clinical remission. Endoscopy at 20 months demonstrated healing of the colonic mucosa. At 22 months he is in sustained clinical remission receiving only infliximab. Because albinism with inflammatory bowel disease suggested Hermansky-Pudlak syndrome, we performed genetic screening using next-generation sequencing in a targeted gene panel analysis for primary immunodeficiency disease and/or inflammatory bowel disease. The patient proved to have a compound heterozygous mutation of the HPS1 gene resulting in Hermansky-Pudlak syndrome type 1. CONCLUSIONS: We consider this report to be the first account of type 1 Hermansky-Pudlak syndrome with infantile-onset of inflammatory bowel disease. Early administration of infliximab was effective. We recommend next-generation sequencing for patients with very early-onset inflammatory bowel disease suspected to be monogenic.

A70s man was admitted to our hospital complaining of chest discomfort. Endoscopic examination showed mucosal erythema and irregularity and an area unstained by iodine in the middle esophagus 21 to 41 cm from the incisors. The biopsy specimen showed moderately differentiated squamous cell carcinoma. An abdominal computed tomographic(CT)scan revealed swelling of the lymph nodes along the celiac artery and abdominal aorta. The patient was diagnosed with unresectable advanced esophageal cancer(cT2N4M0, cStage â £a). Systemic chemotherapy was initiated using a regimen of 5-FU and cisplatin(FP). After 2 courses of chemotherapy, an abdominal CT scan showed reduction of the lymph node swelling along the abdominal aorta, but the lymph node swelling remained along the celiac artery. Therefore, chemoradiotherapy(CRT; FP plus RT 60 Gy/30 Fr at the main tumor and the swelling of lymph nodes along the celiac artery)was administered. An abdominal CT scan showed reduced swelling of the lymph nodes along the abdominal aorta and the celiac artery after CRT. In addition, FP chemotherapy was also administered. APET -CT scan showed no increased FDG up take in the main tumor and swollen lymph nodes after 2 courses of chemotherapy. The complete response(CR)has been maintained for 30 months without therapy.

A 57-year-old woman was diagnosed with advanced gastric cancer with bone marrow metastasis(cT4aN1pM1[MAR], pStage â £). After 18 courses of S-1 and cisplatin and 18 courses of ramucirumab and paclitaxel, the chemotherapy was stopped because of stenosis. We performed endoscopic metallic stent placement, but stenosis reappeared after a month. Subsequently, distal gastrectomy was performed as a palliative surgery. She had no complications and improved appetite, therefore, she resumed chemotherapy after 3 postoperative months and continued for 4 years and 9 months from the first visit. In general, gastric cancer with bone marrow metastasis has a poor prognosis, however, in this case, long-term survival was achieved with palliative surgery.
