[Analysis of Short-Term Results after Introduction of Robotic Gastrectomy for Gastric Cancer at Our Hospital].

BACKGROUND: Robotic gastrectomy(RG)for gastric cancer(GC)has been covered by health insurance since 2018. In this study, we examined the results of RG for GC at our hospital during the initial period of its introduction. MATERIALS AND METHOD: From August 2022 to May 2023, we retrospectively examined the surgical outcomes and short-term postoperative outcomes of the first 9 patients who underwent RG for GC at our hospital. RESULTS: The median patient age was 77(67-82) years, gender was 4 males and 5 females, and distal gastrectomy was performed in all patients. The median operative time was 410(323-486)min, blood loss was 5(1-140)mL, postoperative hospital stay was less than 9 days in all patients, and there was no conversion to laparoscopic or open surgery. There were no postoperative complications of Clavien-Dindo Grade Ⅱ or above. CONCLUSION: In this study, RG for GC was performed safely without intraoperative or postoperative complications.

Serum NY-ESO-1 and p53 antibodies as useful tumor markers in gastric cancer.

Purpose: The NY-ESO-1 antigen is highly immunogenic and often spontaneously induces an immune response in patients with cancer. We conducted a large-scale multicenter cohort study to investigate the utility of serum NY-ESO-1 and p53 antibodies as predictive markers for the postoperative recurrence of gastric cancer. Here, we examined the usefulness of pre-treatment NY-ESO-1 and p53 antibodies as tumor markers for the diagnosis of gastric cancer in combination with carcinoembryonic antigen (CEA) and carbohydrate antigen 19-9 (CA19-9). Methods: A total of 1031 patients with cT3-4 gastric cancer were enrolled in the study. NY-ESO-1 and p53 antibodies were assessed prior to treatment. The positivity of NY-ESO-1 and p53 antibodies, CEA, and CA19-9 was evaluated before treatment. Results: Serum NY-ESO-1 and p53 antibodies were positive in 12.6% and 18.1% of the patients, respectively. Positive NY-ESO-1 antibody response was correlated with male gender, higher cStage, and upper tumor location. However, a positive p53 antibody response was not associated with tumor factors. The combination of NY-ESO-1 or p53 antibody response with CEA and CA19-9, or the 4-factors, was positive in 45.1%, 49.6%, and 53.8% of patients, respectively. Moreover, the 4-factor combination was able to detect >60% of cStage III-IV diseases, which was 14% higher than that with the combination of CEA and CA19-9. Conclusion: The combination of NY-ESO-1 and p53 antibody responses to CEA and CA19-9 increases the diagnostic accuracy of gastric cancer. Serum NY-ESO-1 and p53 antibodies may be useful tumor markers for gastric cancer.

Phase II study of S-1 plus docetaxel as first-line treatment for older patients with advanced gastric cancer (OGSG 0902).

BACKGROUND: Although there is insufficient evidence for the treatment of older patients with advanced gastric cancer, fluorouracil combined with platinum chemotherapy has been recognized as a standard first-line treatment for such populations in Japan despite the lack of efficacy and toxicity data. METHODS: Patients aged 75 years or older with advanced gastric cancer were enrolled. S-1 plus docetaxel (docetaxel: 40 mg/m2, day 1; S-1: 80 mg/m2, days 1-14; q21 days) was repeated every 3 weeks. The primary endpoint was overall response rate. Secondary endpoints were safety, progression-free survival, time to treatment failure, and overall survival. The sample size was calculated as 30 under the hypothesis of an expected response rate of 40% and a threshold response rate of 20%, at a power of 90% and a two-sided alpha value of 5%. RESULTS: From February 2010 to January 2015, 31 patients were enrolled and assessed for efficacy and toxicity. The response rate was 45.2% (95% CI 27.3%-64.0%; p = 0.001) and it exceeded the expected response rate set at 40%. Median progression-free survival was 5.8 months, the 1-year survival rate was 58.1%, and the median survival time was 16.1 months. The major grade 3/4 adverse events were neutropenia (58%), febrile neutropenia (13%), anemia (10%), anorexia (10%), and fatigue (6%). CONCLUSIONS: These findings indicate that S-1 plus docetaxel as first-line treatment for older patients is feasible and that it has promising efficacy against advanced gastric cancer.

Effects of postoperative oral elemental nutritional supplement on skeletal muscle loss after gastrectomy for gastric cancer.

BACKGROUND: We previously showed that daily nutritional intervention with an oral elemental diet (ED) at 300 kcal/day for 6-8 weeks postoperatively decreased the percentage of body weight loss (%BWL), and that the effect was maintained for 1 year. This post hoc analysis aimed to determine whether this intervention decreased skeletal muscle mass loss 1-year post-gastrectomy. METHODS: Data from consecutive, untreated patients with histopathologically confirmed stage I-III gastric adenocarcinoma who planned to undergo total gastrectomy (TG) or distal gastrectomy (DG) and were enrolled in a previously published randomized trial were used. The primary endpoint was the percentage of skeletal muscle mass index (%SMI) loss from baseline at 1 year postoperatively, based on abdominal computed tomography images obtained preoperatively and at 1 year postoperatively. RESULTS: The overall median %SMI loss was lower in the ED versus control group, but the difference was not significant. The difference in %SMI loss in the ED and control groups was greater in patients with TG (10.1 vs. 13.0; P = 0.12) than in those with DG (5.5 vs. 6.8; P = 0.69). A correlation was observed between %BWL and %SMI loss in both groups (ED group, coefficient 0.591; control group, coefficient 0.644; P < 0.001 for both). Type of gastrectomy (coefficient 7.38; P = 0.001) and disease stage (coefficient - 6.43; P = 0.04) were independent predictors of postoperative skeletal muscle mass loss. CONCLUSION: ED administration for 6-8 weeks following gastrectomy had no inhibitory effect on skeletal muscle loss at 1 year postoperatively. CLINICAL TRIAL REGISTRATION: UMIN000023455.

Meta-analysis of three randomized trials of capecitabine plus cisplatin (XP) versus S-1 plus cisplatin (SP) as first-line treatment for advanced gastric cancer.

BACKGROUND: S-1 plus cisplatin (SP) and capecitabine plus cisplatin (XP) are standard first-line regimens for advanced gastric cancer (AGC) worldwide. We conducted a meta-analysis using individual participant data (IPD) to investigate which is more suitable. METHODS: IPD from three randomized trials were collected. In these trials, patients with AGC were randomly allocated to SP (S-1 80-120 mg for 21 days plus cisplatin 60 mg/m2 (q5w)) or XP (capecitabine 2000 mg/m2 for 14 days plus cisplatin 80 mg/m2 (q3w)). RESULTS: In 211 eligible patients, median overall survival (OS) for SP versus XP was 13.5 and 11.7 months (hazard ratio [HR], 0.787; p = 0.114), progression-free survival (PFS) was 6.2 and 5.1 months (HR, 0.767; P = 0.076), and TTF was 5.1 and 4.0 months (HR, 0.611; P = 0.001). The most common grade ≥ 3 adverse events with SP or XP were neutropenia (18% vs. 29%) and anorexia (16% vs.18%). Subgroup analysis demonstrated significant interaction between treatment effect and performance status > 1 (HR, 0.685; P = 0.036), measurable lesion (HR, 0.709; P = 0.049), primary upper third tumor (HR, 0.539; P = 0.040), and differentiated type (HR, 0.549; interaction, 0.236; P = 0.019). For the differentiated type, OS was significantly longer in the SP group (13.2 months) than in the XP group (11.1 months) (HR, 0.549; P = 0.019). For the undifferentiated type, OS was similar in the SP group (14.2 months) and in the XP group (12.4 months) (HR, 0.868; P = 0.476). CONCLUSIONS: SP and XP were both effective and well tolerated. SP might be suitable for the pathological differentiated subtype of AGC. CLINICAL TRIAL REGISTRATION: The HERBIS-2, HERBIS-4A, and XParTS II trials were registered with UMIN-CTR as UMIN000006105, UMIN000006755, and UMIN000006045, respectively.

Proximal Resection Line Determination Using Intraoperative Radiography in Laparoscopic Distal Gastrectomy for Gastric Cancer.

BACKGROUND/AIM: Laparoscopic distal gastrectomy for gastric cancer has become a common procedure in many institutions. As manual palpation is impossible, various methods have been developed to identify the location of the tumor and determine the proximal resection line. Intraoperative endoscopy requires manpower and is time-consuming. The authors take an intraoperative X-ray. Here, we demonstrate our methods and outcomes. PATIENTS AND METHODS: We preoperatively applied metal clips just proximal to the tumor through esophagogastroduodenoscopy. During surgery, we applied metal vessel clips to the greater and lesser curvatures of the planned resection line of the stomach and took an intraoperative X-ray to examine the distance between the planned resection line and the tumor. If the distance was appropriate, the stomach was resected on the planned line, and if the distance was judged to be insufficient, the stomach was resected on the more proximal line, as appropriate. An intraoperative frozen section of the proximal resection margin was examined, as appropriate. RESULTS: We performed this method for 71 patients. Tumors were successfully resected together with preoperative endoscopic clips in all patients. In five patients, intraoperative frozen section of the proximal resection margins was positive; however, additional resection confirmed negative margins. One patient underwent total gastrectomy, and the remaining 70 patients underwent distal gastrectomy. CONCLUSION: An intraoperative X-ray seems to be a simple and useful method for identifying the location of the tumor and determining the proximal resection line.

[A Case of Hepatocellular Carcinoma with Haemobilia after Transcatheter Hepatic Arterial Embolization for Tumor Rupture].

A 79-year-old man was scheduled for surgery for hepatocellular carcinoma(HCC)after transcatheter hepatic arterial embolization for rupture. Two weeks before surgery, the patient came to our hospital with a chief complaint of back pain. First, we performed biliary drainage, under the diagnosis of HCC with obstructive jaundice due to haemobilia. Hepatectomy was performed when the patient's condition stabilized. It should be kept in mind that haemobilia may occur after TAE for HCC with bile duct tumor thrombus, and appropriate treatment should be performed when bleeding occurs.

[A Case of Colon Metastasis from Gastric Cancer Treated by Laparoscopic-Assisted Segmental Colectomy].

We report a case of colon metastasis from gastric cancer treated by laparoscopic-assisted segmental colectomy. An 81-year-old man was undergone distal gastrectomy, D2 dissection and Billroth Ⅰ reconstruction for gastric cancer 3 years previously, with a final diagnosis of gastric cancer L, Post, Type 2, sig/por2, pT4a(SE), pN3b(30/56), H0, P0, M0, pStage ⅢC. Three years after gastrectomy, CT scan showed an elevated lesion in the transverse colon, which was suspected to be metastatic colorectal cancer on closer examination. As no metastatic lesions were found other than the tumor of transverse colon, we performed laparoscopic-assisted segmental colon resection. A small incision was placed in the umbilical region, and the transverse colon was extracted from the umbilical region after dissection of the adhesions by single-incision laparoscopic surgery. The transverse colon containing the mass lesion was partially resected extracorporeally and reconstructed with a functional end-to-end anastomosis. The postoperative pathological findings revealed tumor cells predominantly below the submucosal layer and partly showing the signet ring cell carcinoma, and the transvers colon tumor was diagnosed as a metastasis from gastric cancer. The postoperative course was uneventful and the patient was discharged 8 days after surgery, and is alive for 10 months after the segmental colon resection followed by chemotherapy.

[A Case of Recurrent Esophageal Cancer with Long-Term Survival Treated by S-1 Monotherapy].

We report a case of recurrent esophageal cancer with long-term survival treated by S-1 monotherapy. A 66-year-old man underwent subtotal esophagectomy, two-field lymphadenectomy after 2 courses of DCF chemotherapy for esophageal cancer 1 year earlier. The final diagnosis was esophageal cancer, Lt, CT-Type 2, ypT3, ypN0(0/62), M0, ypStage Ⅲ. At 6 months after esophagectomy, CT scan revealed mediastinal lymph node metastasis and pleural dissemination, and paclitaxel monotherapy was performed, but lymph node re-enlargement was observed on CT at 12 months after esophagectomy. Chemotherapy with S-1 monotherapy was performed, and 3 months after initiation of S-1 monotherapy, CT showed reduced lymph node metastases and pleural dissemination remained reduced. Adverse events were CTCAE v5.0 Grade 2 thrombocytopenia and diarrhoea, but no Grade 3 or higher adverse events were observed. Long-term survival was achieved with no disease progression for more than 2.5 years after initiation of S-1 monotherapy.

[A Rare Case of Advanced Gastric Cancer with Duodenal Intramural Metastasis].

Here we report the case of a patient with advanced gastric cancer who presented with duodenal intramural metastasis based on the pathological results after surgery. The patient was 78-year-old female, who was referred to our department for further evaluation and treatment of upper abdominal pain. An upper gastrointestinal series demonstrated a tumor occupying the lesser curvature of the gastric body. Biopsy specimens from the tumor demonstrated moderately to poorly differentiated adenocarcinoma. A computed tomography scan showed thickening of the gastric wall and swelling of the regional lymph nodes. The patient underwent distal gastrectomy and D2 lymph node dissection for gastric cancer. A histopathological examination disclosed that the gastric tumor was poorly differentiated adenocarcinoma with severe lymphatic permeation and also demonstrated the other poorly differentiated adenocarcinoma occupying the part of the muscularis propria layer of the duodenum. The gastric tumor was not contiguous with the duodenal tumor, and the duodenal cancer cells had the same pathological characteristics as the primary gastric cancer cells; therefore, we diagnosed the duodenal tumor as an intramural metastasis from gastric cancer. The patient's disease was staged as pT4aN3bM1, Stage Ⅳ according to the TNM classification. We report this rare case along with a discussion of the literature.

[A Case of Sigmoid Rectal Cancer with a Vesicoconstrictor Fistula Curatively Resected after Neoadjuvant Chemotherapy].

A 50-year-old man presented with fecaluria and was diagnosed with sigmoid colon cancer with a colovesical fistula. Total bladder resection was determined to be necessary for curative resection at the time of diagnosis. In anticipation of bladder preservation, 6 courses of mFOLFOX6 plus panitumumab were administered after transverse colostomy, resulting in marked tumor regression and a decision to proceed with surgery. The patient underwent robotic-assisted low anterior resection of the rectum and partial cystectomy, which yielded pathological radical treatment. We report a case of sigmoid colon cancer with a colovesical fistula complicated by bladder invasion, in which preoperative chemotherapy was effective and total cystectomy was avoided, allowing bladder preservation.

Histology Classification Highlights Differences in Efficacy of S-1 versus Capecitabine, in Combination with Cisplatin, for HER2-Negative Unresectable Advanced or Recurrent Gastric Cancer with Measurable Disease.

It has been suggested that the therapeutic efficacy of S-1 + cisplatin (SP) and capecitabine + cisplatin (XP) may differ depending on the histology of the tumor, but no clear evidence exists. Individual participant data were obtained from three randomized phase II trials in which such patients received either SP (S-1 [40-60 mg twice daily for 21 days] plus cisplatin [60 mg/m2 on day 8], every 5 weeks) or XP (capecitabine [1000 mg/m2 twice daily for 14 days] plus cisplatin [80 mg/m2 on day 1], every 3 weeks). A total of 162 patients were included, with 79 patients in the SP arm and 83 patients in the XP arm. Although there was also no difference between arms in ORR according to histological classification, differentiated tumors showed a significantly better OS (but not PFS) for SP versus XP that was associated with a deeper tumor shrinkage. Undifferentiated tumors showed a consistently better OS, and PFS for SP versus XP, likely because cases without tumor shrinkage tended to be fewer for SP. Our data thus showed that SP was superior to XP in this setting, but there were qualitative differences in therapeutic efficacy dependent on tumor histology.

[Analysis of Short-Term Outcomes and Nutritional Assessment of Elderly Gastric Cancer Surgery Cases].

BACKGROUND: We analyzed the short-term outcomes and nutritional assessment of gastric cancer surgery patients who underwent exercise intervention after gastrectomy. MATERIALS AND METHOD: Gastric cancer patients who underwent gastrectomy at our department from January 2021 were included in the study. Postoperative exercise intervention(lower limb training) was performed in gastric cancer patients aged 75 years or older(group H: 7 patients)and compared retrospectively with gastric cancer patients younger than 75 years(group L: 10 patients)who did not receive exercise intervention. The rate of decrease in each index after 1 week was compared between the 2 groups. RESULTS: Postoperative complications(yes/no) were 3/4(42.8%)in group H and 2/8(20.0%)in group L(p=0.59); postoperative hospital stay was 11.5(10.8-21.3) days in group H and 11.0(9.0-14.0)days in group L(p=0.37). The percentage decrease in each index was as follows: for BMI in groups H/L: 2.9/5.6%(p=0.17), grip strength in groups H/L: 2.4/－7.6%(p=0.07), skeletal muscle mass in groups H/L: －2.3/7.0%(p=1.00), PNI in groups H/L: 26.6/18.1%(p=0.12). CONCLUSION: In this study, no significant differences were noted in postoperative complication rates or postoperative hospital stay between groups H and L.

A phase II study of S-1 therapy for patients with advanced and recurrent esophageal cancer resistant or intolerable to fluorouracil, platinum, and taxane therapy (OGSG 1404).

BACKGROUND: Fluorouracil (FU), platinum (PT), and taxane (TAX) therapy was the standard chemotherapy for esophageal squamous cell carcinoma (ESCC) before the era of anti-programmed death-1 antibodies. The aim of this phase II trial was to evaluate the efficacy and safety of S-1 monotherapy for patients with recurrent or metastatic (R/M) ESCC resistant or intolerable to FU, PT, and TAX therapy. METHODS: Eligible patients had R/M ESCC; no prior S-1 use; were intolerant or refractory to prior FU, PT, and TAX therapy; aged ≧ 20 years; and Eastern Cooperative Oncology Group performance status 0 or 1. S-1 was administered orally from days 1 to 28, every 6 weeks until disease progression. The primary endpoint was the disease control rate (DCR) for each patient, assessed by Response Evaluation Criteria in Solid Tumors, version 1.1. Secondary endpoints were overall survival, progression-free survival, time to treatment failure, response rate, and toxicity. RESULTS: Between October 2015 and December 2017, 17 patients were recruited, and the trial was terminated because of slow accrual. The DCR was 46.7%. The response rate was 13.3%. The median progression-free survival was 2.0 months. The median time to treatment failure was 1.9 months. The median overall survival was 8.4 months, and the 1 year overall survival rate was 30.5%. CONCLUSIONS: Although this trial closed early because of slow accrual, we observed modest clinical activity with S-1 in patients with R/M ESCC who could not tolerate or whose tumors were refractory to FU, PT, and TAX therapy.

Real-world effectiveness of third- or later-line treatment in Japanese patients with HER2-positive, unresectable, recurrent or metastatic gastric cancer: a retrospective observational study.

BACKGROUND: Real-world evidence on the preference for and effectiveness of third- or later-line (3L +) monotherapy for HER2-positive gastric cancer is limited in Japan. This study evaluated the utility of nivolumab, irinotecan, and trifluridine/tipiracil (FTD/TPI) monotherapy as 3L + treatment in Japanese patients with HER2-positive gastric/gastroesophageal junction (G/GEJ) cancer who were previously treated with trastuzumab. METHODS: In this multicenter, retrospective, observational study (20 centers), data of eligible patients were extracted from medical records (September 22, 2017-March 31, 2020), with follow-up until June 30, 2020. Outcomes included overall survival (OS), real-world progression-free survival (rwPFS), time to treatment failure (TTF), objective response rate (ORR; complete response [CR] + partial response [PR]), and disease control rate (DCR). RESULTS: Of 127 enrolled patients, the overall analysis population comprised 117 patients (median [range] age, 71 [38-89] years). The most commonly prescribed 3L + monotherapy was nivolumab (n = 100), followed by irinotecan (n = 12) and FTD/TPI (n = 5). The median (95% confidence interval [CI]) OS, rwPFS, and TTF were 6.2 (4.5-8.0), 1.9 (1.5-2.3), and 1.8 (1.5-2.2) months, respectively, at median (range) 150 (25-1007) days of follow-up. The ORR (CR + PR) and DCR were 9.0% (1% + 8%) and 32.0%, respectively. Factors such as higher neutrophil-lymphocyte ratio (≥ 2.54), Glasgow prognostic score (≥ 1), Eastern Cooperative Oncology Group performance status (ECOG PS; ≥ 2), and hepatic metastasis significantly impacted OS. CONCLUSIONS: The observed OS in this study for HER2-positive G/GEJ cancer was shorter than that reported previously, suggesting that the effectiveness of nivolumab, irinotecan, or FTD/TPI as 3L + therapy may be limited.

[Analysis of Chemotherapy-Induced Nausea and Vomiting during Chemotherapy for Gastric Cancer].

BACKGROUND: Chemotherapy-induced nausea and vomiting(CINV)are typical side effects caused by chemotherapy. We analyzed CINV during first-line chemotherapy for gastric cancer. MATERIALS AND METHOD: Thirty-one patients who received first-line chemotherapy for gastric cancer were retrospectively assessed for CINV. RESULTS: The median age was 70 years, and the gender(male/female)was 23/8 cases. NK1 receptor antagonist, 5-HT3 receptor antagonist, and dexamethasone were used as antiemetic agents in 29 patients(94%). Sixteen patients(52%)had Grade 1 or higher nausea, and 6 patients (19%)had Grade 1 or higher vomiting, and complete control of nausea and vomiting was achieved in 21 patients(68%). Nausea was significantly more frequent in patients with liver metastasis(p=0.0008), but there was no significant difference in vomiting(p=1.0000). There was no significant difference in the occurrence of CINV between chemotherapy regimens or combination of olanzapine. CONCLUSION: During first-line chemotherapy for gastric cancer, 3 antiemetic agents were used in 94% of cases, and the complete control rate of CINV was 67.8%.

[A Case of Early Gastric Cancer with Adachi Type â ¥ Vascular Anomaly Treated by Laparoscopic Distal Gastrectomy].

We report a case of early gastric cancer with Adachi Type Ⅵ vascular anomaly treated by laparoscopic distal gastrectomy. An 81-year-old woman was admitted because of anorexia, and was diagnosed with early gastric cancer. Preoperative MDCT revealed Adachi Type Ⅵ vascular anomaly, where the hepatic artery does not appear at the superior border of the pancreas. The patient was treated successfully with laparoscopic distal gastrectomy with D1+lymph node dissection. At surgery, we identified the portal vein, then, dissection of No. 8a lymph nodes was performed. The postoperative course was uneventful and the patient was discharged 10 days after surgery. The final pathology result showed gastric cancer, M, Less, Type 0-Ⅱc+Ⅲ, 58×50 mm, tub1>pap, pT1a(M), Ly0, V0, pN0(0/40), H0, P0, M0, pStage ⅠA. We understand the arterial running pattern before surgery by using MDCT, and performed laparoscopic surgery safely.

[A Case of Laparoscopic Resection Using the ICG Fluorescence for Peritoneal Disseminations of Hepatocellular Carcinoma].

A 71-year-old male had repeated resection and transcatheter arterial chemo-embolization(TACE)for hepatocellular carcinoma(HCC). Treatment with lenvatinib was started due to multiple liver recurrences and peritoneal disseminations. Since only the disseminated lesion had increased, it was decided to perform laparoscopic resection. Indocyanine green(ICG) was intravenously injected the day before surgery. Disseminated lesions could be easily detected with intraoperative fluorescence imaging, and we could completely resect disseminated lesions. The ICG fluorescence could be considered to be useful in laparoscopic resection for peritoneal dissemination of HCC.

[A Case of Stage â £ Gastric Cancer Completely Resected after Successful Second-Line Chemotherapy].

A 60s man was diagnosed with advanced gastric cancer(cT4b[PAN], cN+, cM0, cStage ⅣA). He started first-line chemotherapy consisting of S-1 and cisplatin, but tumor markers remained elevated and CT showed cancer progression. He then started second-line chemotherapy consisting of ramucirumab and paclitaxel. The tumor markers decreased, and CT revealed tumor regression. A distal gastrectomy with D2 lymph node dissection was performed as conversion surgery. The patient had an uncomplicated postoperative course and was discharged early from the hospital. A histological analysis confirmed complete resection of the Grade 1a tumor. The RAM plus PTX regimen was restarted on postoperative day 57. At 15 months postoperative, the patient remained alive and relapse-free.

[A Case of Recurrent Sigmoid Colon Cancer with Peritoneal Metastasis and Liver Metastasis Successfully Treated with Capecitabine plus Bevacizumab].

A 78-year-old man had undergone a laparoscopic sigmoid colon resection; left ureteral resection; and a ureteral reconstruction for sigmoid colon cancer with left ureteral invasion. The patient did not wish to undergo postoperative adjuvant chemotherapy, and he was followed up at fixed intervals. Six months after surgery, CT revealed peritoneal metastasis and liver metastasis(S6). Considering his advanced age and adverse events, the patient was started on capecitabine plus bevacizumab therapy. The patient was able to continue the treatment, even though he had to suspend and reduce the dose due to adverse events of hand-foot syndrome, and achieved CR by CT after 21 courses of treatment. Chemotherapy was discontinued after 24 courses, CR was maintained for 5 years, and the patient is still alive with no evidence of recurrence.
