Serum NY-ESO-1 antibody as a predictive biomarker for postoperative recurrence of gastric cancer: a multicenter prospective observational study.

BACKGROUND: No reliable marker has been identified to predict postoperative recurrence of gastric cancer. We designed a clinical trial to investigate the utility of serum NY-ESO-1 antibody responses as a predictive marker for postoperative recurrence in gastric cancer. METHODS: A multicenter prospective study was conducted between 2012 and 2021. Patients with resectable cT3-4 gastric cancer were included. Postoperative NY-ESO-1 and p53 antibody responses were serially evaluated every 3 months for 1 year in patients with positive preoperative antibody responses. The recurrence rate was assessed by the positivity of antibody responses at 3 and 12 months postoperatively. RESULTS: Among 1001 patients, preoperative NY-ESO-1 and p53 antibody responses were positive in 12.6% and 18.1% of patients, respectively. NY-ESO-1 antibody responses became negative postoperatively in non-recurrent patients (negativity rates; 45% and 78% at 3 and 12 months, respectively), but remained positive in recurrent patients (negativity rates; 9% and 8%, respectively). p53 antibody responses remained positive in non-recurrent patients. In multivariate analysis, NY-ESO-1 antibody positivity at 3 months (P < 0.03) and 12 months (P < 0.001) were independent prognostic factors for a shorter recurrence-free interval. CONCLUSIONS: Serum NY-ESO-1 antibodies may be a useful predictive marker for postoperative recurrence in gastric cancer. CLINICAL TRIAL REGISTRATION: UMIN000007925.

Tumor Response Predicts Survival Time of Nivolumab Monotherapy for Advanced Gastric Cancer: A Subgroup Analysis of the DELIVER Trial (JACCRO GC-08).

BACKGROUND: This prospective observational study evaluated the real-world effectiveness of nivolumab monotherapy in previously treated advanced gastric cancer (GC). A preplanned 2-year final analysis was performed to confirm survival and tumor behavior with nivolumab monotherapy. PATIENTS AND METHODS: The primary endpoint was overall survival (OS). The data regarding tumor size were prospectively collected and evaluated using the RECIST criteria. Exploratory analyses were performed for survival according to the tumor response and depth of response (DpR) in patients with measurable lesions who were receiving nivolumab monotherapy as third- or later-line therapy. RESULTS: In 487 patients, the median OS and progression-free survival (PFS) were 5.8 (95% CI 5.3-6.9) months and 1.8 (95% CI 1.7-2.0) months, respectively. The response rate (RR) was 14.5% in 282 patients with measurable lesions. In 234 patients treated with third- or later-line, the DpR was found to be associated with PFS and OS in the Spearman analysis (r = 0.55 and 0.44, respectively) as well as using a discrete variable. When the DpR was divided into 5 groups (-20%≥DpR; -20%

Long-Term Effects of Oral Nutritional Supplements After Gastrectomy for Gastric Cancer: A Survival Analysis from a Multicenter, Open-Label, Randomized Controlled Trial.

BACKGROUND: Weight loss (WL) after gastrectomy for gastric cancer is associated with both decreased compliance with adjuvant chemotherapy and impaired survival. This study examined the effects of administering oral nutritional supplements (ONS) for 3 months after gastrectomy in terms of compliance with adjuvant chemotherapy and survival outcomes. METHODS: This large-scale, multicenter, open-label, randomized controlled trial enrolled 1,003 gastric cancer patients undergoing curative gastrectomy. Patients were assigned to the control group (n = 503) or ONS group (n = 500). In the ONS group, 400 kcal/day of ONS was recommended in addition to a regular diet for 3 months after gastrectomy. Compliance with adjuvant chemotherapy and survival outcomes were compared between the two groups. RESULTS: Compared with the control group, the ONS group showed significantly decreased WL at 3 months after gastrectomy (8.6 ± 6.1 vs. 7.2 ± 5.7%, respectively, P = 0.0004). The control and ONS groups did not differ regarding the induction rate of adjuvant chemotherapy (84.9 vs. 82.8%, respectively, P = 0.614) or the continuation rate at 3 months postoperatively (75.3 vs. 76.6%, respectively, P = 0.809). Oral nutritional supplements for 3 months showed no survival benefit; the 3- and 5-year overall survival (OS) rates were 91.3% and 87.6% in the control group and 89.6% and 86.4% in the ONS group, respectively, indicating no significant difference (P = 0.548). Subgroup analysis could not detect a population in which ONS administration increased OS. CONCLUSIONS: Administration of ONS for 3 months after gastrectomy was not associated with increased compliance with adjuvant chemotherapy or with improved prognosis.

Distal gastrectomy and Roux-en-Y reconstruction for refractory reflux esophagitis after proximal gastrectomy and esophagogastric anastomosis reconstruction.

Refractory gastroesophageal reflux disease can develop after proximal gastrectomy and esophagogastrostomy. We introduce a new method that combines distal gastrectomy and Roux-en-Y reconstruction to treat refractory reflux esophagitis in patients who have undergone proximal gastrectomy and esophagogastric anastomosis reconstruction. This novel method may be useful not only for alleviating the symptoms of gastroesophageal reflux disease but also for preventing future esophageal malignancies arising from long-term reflux esophagitis.

Prognostic factors and significance of postoperative adjuvant chemotherapy in patients with advanced gastric cancer undergoing neoadjuvant chemotherapy followed by gastrectomy.

PURPOSE: In Japan, gastrectomy with D2 lymph node dissection and postoperative adjuvant chemotherapy are the standard treatments for locally advanced gastric cancer. Neoadjuvant chemotherapy (NAC) is not affected by postgastrectomy syndromes or postoperative complications. This multicenter retrospective study investigated the prognostic factors and significance of postoperative adjuvant chemotherapy in patients with advanced gastric cancer who underwent NAC followed by gastrectomy. METHODS: Consecutive patients (n = 221) with advanced gastric cancer who underwent NAC followed by curative surgery were enrolled in this study. Prognostic factors including postoperative adjuvant chemotherapy were investigated using univariate and multivariate analyses. RESULTS: A multivariate analysis revealed that pathological lymph node metastasis (ypN) status and postoperative adjuvant chemotherapy were independent prognostic factors for the overall and relapse-free survival. Forty-five patients (20.4%) did not receive postoperative adjuvant chemotherapy. There were no significant differences between patients with and without adjuvant chemotherapy for all factors, except age. The most common reason for not undergoing postoperative adjuvant chemotherapy was a poor condition (n = 23). CONCLUSIONS: ypN status and postoperative adjuvant chemotherapy were independent prognostic factors in gastric cancer patients who underwent NAC followed by curative gastrectomy. It is important to maintain the patient's condition during NAC and the perioperative period so that they can receive postoperative adjuvant chemotherapy.

[A Study on the Significance of NST Early Intervention for Cancer Patients].

BACKGROUND: Cancer patients are often complicated by weight loss and malnutrition, thus it is important to provide nutritional therapy in parallel with disease treatment. This study examined the significance of early intervention by NST for cancer patients. METHODS: Seventy-five cancer patients out of 281 patients who underwent NST intervention between July 2021 and June 2022 were included. Intervention outcomes, such as energy and protein sufficiency(=intake/target), and final evaluation by a NST nutritionist at the end of the intervention("improvement"/"unchanged"/"disease progression"/ "death"), were compared between patients who received NST intervention within 7 days from admission(Group A)and after 7 days from admission(Group B). RESULTS: Nutritional sufficiency at the end of NST intervention was higher in Group A for both energy and protein, and the proportion of"improvement"was higher in Group A for the final evaluation by a NST nutritionist. Patients' situation(pre-initial treatment/post-chemotherapy/post-surgery/worsening nutritional status during follow-up)was biased between 2 groups, however Group A showed better results for nutritional sufficiency rate and final evaluation in each subgroup of patients' situation. CONCLUSION: Early intervention may improve the effectiveness of NST for cancer patients. It is important to extract subjects and start NST intervention at early timing.

The impact of time to postoperative recurrence on the prognosis of patients with esophageal cancer post recurrence: exploratory analysis of OGSG 1003.

BACKGROUND: The association between recurrence timing and prognosis in patients with locally advanced resectable esophageal cancer undergoing neoadjuvant chemotherapy (NAC) followed by esophagectomy remains unclear. This study aimed to clarify this association using multicenter prospective clinical trial data. METHODS: Among 162 patients enrolled in a NAC phase II study comparing the efficacy of cisplatin and fluorouracil plus docetaxel with cisplatin and fluorouracil plus adriamycin, 64 patients with recurrence after R0 resection were included in this study. We evaluated the association between recurrence timing and overall survival after recurrence (OSr), along with clinicopathological factors associated with recurrence timing and OSr. RESULTS: Among 64 patients, 46 (71.9%) and 59 (92.2%) experienced recurrence within 1 and 2 years after surgery, respectively. Groups based on recurrence timing, including ≤ 6, 6-12, and > 12 months, had median OSr of 3.6, 13.9, and 13.4 months, respectively. The prognosis was significantly poorer for patients with recurrence ≤ 6 months after surgery than for other patients (P < 0.001). Multivariate analysis revealed pathological lymph node staging as an independent factor associated with early recurrence (odds ratio: 3.46, 95% confidence interval: 1.47-8.02, P = 0.0045). On the other hand, multivariate analysis for factors associated with OSr revealed pT (hazard ratio [HR]: 1.91, 95%CI 1.26-2.88, P = 0.0022), early recurrence (HR: 6.88, 95%CI 2.68-17.6, P < 0.001), and treatment after recurrence, with both local treatment (HR: 0.47, 95%CI 0.22-0.98, P = 0.043) and chemotherapy (HR: 0.25, 95%CI 0.11-0.58, P = 0.0011) as independent prognostic factors. CONCLUSION: Patients with advanced esophageal cancer experiencing recurrence within 6 months after esophagectomy following NAC have an extremely poor prognosis, suggesting that an advanced pN stage is associated with early recurrence.

Chemoradiotherapy versus triplet chemotherapy as initial therapy for T4b esophageal cancer: survival results from a multicenter randomized Phase 2 trial.

BACKGROUND: We report the long-term results as primary endpoint in a multicentre randomized prospective Phase 2 trial which compared chemoradiotherapy (CRT) and triplet chemotherapy (CT) as the initial therapy for conversion surgery (CS) in T4b esophageal cancer (EC). METHODS: Patients with T4b EC were randomly assigned to the CRT group or CT group as initial treatment. CS was performed if resectable after initial or secondary treatment. The primary endpoint was 2-year overall survival, analysed by intention-to-treat. RESULTS: The median follow-up period was 43.8 months. The 2-year survival rate was higher in the CRT group (55.1%; 95% CI: 41.1-68.3%) compared to the CT group (34.7%; 95% CI: 22.8-48.9%), although the difference was not significant (P = 0.11). Local and regional lymph node recurrence in patients undergoing R0 resection was significantly higher in the CT group compared to the CRT group (local: 30% versus 8%, respectively, P = 0.03; regional: 37% versus 8%, respectively, P = 0.002). CONCLUSIONS: Upfront CT was not superior to upfront CRT as induction therapy for T4b EC in terms of 2-year survival and was significantly inferior to upfront CRT in terms of local and regional control.

Three-Course Neoadjuvant Chemotherapy Associated with Unfavorable Survival of Non-responders to the First Two Courses for Locally Advanced Esophageal Cancer.

BACKGROUND: Three-course neoadjuvant chemotherapy (NAC) followed by surgery has become a standard of care for locally advanced esophageal cancer (EC). However, some patients occasionally experience a poor tumor response to the third course and have a poor clinical outcome. METHODS: An exploratory analysis of data from the authors' recent multicenter randomized phase 2 trial compared patients with locally advanced EC who received two courses (n = 78) and those who received three courses (n = 68) of NAC. The association between tumor response and clinico-pathologic factors, including survival, was evaluated to identify risk factors in the three-course group. RESULTS: Of 68 patients who received three courses of NAC, 28 (41.2%) had a tumor reduction rate lower than 10% during the third course. This rate was associated with unfavorable overall survival (OS) and progression-free survival (PFS) compared with a tumor reduction rate of 10% or higher (2-year OS rate: 63.5% vs. 89.3%, P = 0.007; 2-year PFS rate: 52.6% vs. 79.7%, P = 0.020). The independent prognostic factors for OS were tumor reduction rate lower than 10% during the third course (hazard ratio [HR], 2.735; 95% confidence interval [CI] 1.041-7.188; P = 0.041) and age of 65 years or older (HR, 9.557, 95% CI 1.240-73.63; P = 0.030). Receiver operating characteristic curve and multivariable logistic regression analyses identified a tumor reduction rate lower than 50% after the first two courses as an independent predictor of a tumor reduction rate lower than 10% during the third course of NAC (HR, 4.315; 95% CI 1.329-14.02; P = 0.015). CONCLUSION: Continuing NAC through a third course may worsen survival for patients who do not experience a response to the first two courses in locally advanced EC.

Analysis of the risk factors for osteoporosis and its prevalence after gastrectomy for gastric cancer in older patients: a prospective study.

PURPOSE: Osteoporosis leads to fragility fractures and is a major public health problem. We conducted this study to analyze the prevalence of and risk factors for osteoporosis after gastrectomy in older patients. METHODS: This multicenter prospective trial comprised older patients without recurrence of gastric cancer for > 3 years after curative surgery. The prevalence of osteoporosis was identified using the World Health Organization bone mineral density (BMD)-based definition. Univariate and multivariate analyses were performed to identify the risk factors for osteoporosis. RESULTS: BMD values were measured in 267 of the 271 enrolled patients. The prevalence of osteoporosis was 38.2% (men 24.0%; women 60%). Analysis using FRAX® revealed that 51.7% of patients were candidates for pharmacologic therapy. Female sex (odds ratio [OR] 5.16, 95% confidence interval [CI] 2.61-10.2), age (OR 1.06, 95% CI 1.00-1.12), low body mass index (< 19.0 kg/m2) after gastrectomy (OR 5.31, 95% CI 2.79-10.13), and history of fracture (OR 2.06, 95% CI 1.06-4.02) were independently associated with osteoporosis. CONCLUSIONS: The prevalence of osteoporosis in older patients after gastrectomy was 38.2%. Moreover, female sex, age, low body mass index after gastrectomy, and a history of fracture were risk factors significantly associated with osteoporosis. Thus, older patients undergoing gastrectomy should have proactive surveillance and receive treatment for osteoporosis.

[A Case of Hepatocellular Carcinoma Extending into Right Atrium Was Resected Successfully Using Cardiopulmonary Bypass].

A 59-year-old male was referred to our hospital for a thorough examination of liver function abnormality in the background of chronic hepatitis C. Abdominal contrast-enhanced CT showed multiple tumors in the right lobe of the liver, and an 8 cm tumor occupying S7, a tumor thrombus extending from the right hepatic vein to the inferior vena cava, and a tumor thrombus in the right branch of the portal vein. The patient was diagnosed with hepatocellular carcinoma, cT4N0M0, cStage ⅣA. After 5 courses of hepatic arterial infusion therapy, the intrahepatic lesion was significantly reduced, but micropulmonary metastasis appeared, and the tumor thrombus in the inferior vena cava increased to the thoracic inferior vena cava and just below the tricuspid valve. The patient had difficulty blocking blood flow in the inferior vena cava in the pericardial sac. The patient underwent right hepatectomy, tumor thrombus resection of the inferior vena cava, combined resection of the inferior vena cava, and bovine pericardial patch reconstruction under artificial cardiopulmonary support. He was discharged on the 23rd day after surgery and has been under outpatient observation for 16 months while receiving molecular-targeted drugs for lung metastasis.

[A Case of Thoracic Esophageal Cancer Treated with COVID-19 Pneumonia during Preoperative Chemoradiotherapy(CRT)].

INTRODUCTION: There is concerned that prognosis of cancer-bearing patients is adversely affected by postponement of cancer treatment due to infection with a new type of coronavirus(COVID-19). We report a case of thoracic esophageal cancer treated with COVID-19 pneumonia during preoperative CRT. A 60-year-old female diagnosed as having Stage Ⅳ thoracic esophageal cancer(cT3N0M1LYM[104R])started receiving preoperative chemoradiotherapy. On the 12th day, she had a fever and was diagnosed with COVID-19 infection. CRT temporarily interrupted and she was treated for COVID-19 pneumonia preferentially. CRT was resumed promptly after remission. Finally, video-Assisted radical esophagectomy was performed. There were no postoperative complications. Nivolumab was started as an adjuvant therapy on the 2nd postoperative months. CONCLUSIONS: We experienced a case of thoracic esophageal cancer in which COVID-19 pneumonia was treated during preoperative CRT, and CRT and surgery were completed without complications by appropriate treatment.

[A Case of Long-Term Survival with Multidisciplinary Treatment for Postoperative Local Recurrence of Intrahepatic Cholangiocarcinoma].

We report a case of local recurrence of intrahepatic bile duct cancer that was successfully treated using chemotherapy and radiation therapy. A man in his 80s underwent hepatic resection for intrahepatic cholangiocarcinoma, and abdominal CT 11 months after surgery revealed local recurrence around the dissected surface. He was diagnosed with a local recurrence of intrahepatic cholangiocarcinoma and started systemic chemotherapy(GEM plus CDDP plus S-1). After 11 courses of chemotherapy, stereotactic body radiation therapy(SBRT)was administered to the same site at 50 Gy/10 Fr, as the local recurrence area had increased, although no distant metastases were detected on imaging. The patient was then started on chemotherapy( GEM plus S-1), but after 2 courses, 8 courses of GEM alone were administered at the patient's request. No increase in tumor markers was observed, but an increase in the low-absorption area was observed on imaging. Thereafter, the regimen was changed to S-1. Three months later, the same area was reduced in size and obscured on imaging evaluation. The patient is still taking it 12 months later. No recurrence has been observed since 2 years and 7 months after the start of treatment for local recurrence. This case suggested that multidisciplinary therapy might be useful for local recurrence of intrahepatic cholangiocarcinoma.

[A Case of Conversion Surgery after Long-Term Chemotherapy for Pancreatic Cancer with Peritoneal Metastasis].

A 66-year-old woman was referred to the gastroenterology division of our hospital due to elevation of serum CEA level. Contrast-enhanced CT showed a hypovascular tumor at the body of pancreas. She was diagnosed with pancreatic cancer by EUS-FNA. By laparotomy, we found white nodules on mesentery and abdominal wall, which were diagnosed as peritoneal metastasis. After systemic chemotherapy with 9 courses of gemcitabine(GEM)plus nab-paclitaxel(PTX)and 30 courses of mFOLFIRINOX, the tumor had shrunk and serum CA19-9 level were remarkably decreased. Distal pancreatectomy was performed as conversion surgery. Pathological analysis revealed no remnant cancer cells in the primary tumor or the lymph nodes, confirming a pCR. S-1 was started as adjuvant chemotherapy, and she remains alive without recurrence 8 months after surgery.

[A Case of Sister Mary Joseph's Nodule after Radiation Therapy for Cervical Cancer].

An umbilical metastasis from an internal malignancy is called Sister Mary Joseph's nodule(SMJN)and has a poor prognosis. Herein, we report a case of umbilical metastasis of cervical cancer. A woman in her eighties underwent radiation therapy for cervical cancer(cT3bN0M0, cStage ⅢB). Primary tumor shrank after treatment, suggesting that radiation therapy induced complete response. Two years and 9 months after treatment, the patient presented with umbilical pain. A CT scan showed an umbilical mass near the umbilical hernia. PET-CT demonstrated high accumulation of FDG at the mass, which led to suspicion of umbilical metastasis(SMJN). Although she underwent radical surgery, she died from cancer 8 months after surgery.

[A Case of Recurrent Gastric Cancer with Long-Term Control via Two Resections and Multidisciplinary Treatment Including Nivolumab].

A 78-year-old woman underwent total gastrectomy with distal pancreatectomy and splenectomy for type 3 gastric cancer and a cystic tumor of the pancreas. Her pathological diagnosis was pT4aN3bM0, pStage ⅢC, and HER2-negative. Capecitabine and oxaliplatin was started as an adjuvant therapy, and capecitabine was administered until 1 year postoperatively. Thirteen months after surgery, she had a recurrence in S3 of the liver and underwent liver resection due to solitary metastasis. The postoperative diagnosis was peritoneal dissemination of gastric cancer with invasion of the falciform ligament. S-1 was started postoperatively. Ten months after surgery, she had a recurrence in S3 of the liver and underwent repeated resection. It invaded into the diaphragm and pericardium, and the final diagnosis was recurrent peritoneal dissemination of gastric cancer. After 5 courses of paclitaxel and ramucirumab, nivolumab was started as a fourth-line therapy for the recurrence of the right supraclavicular lymph nodes, bone, and liver. She had some immune-related adverse events(irAE), including hypothyroidism and hypoadrenocorticism, which required management, but she maintained PR more than 2 years after the initiation of the treatment. Multimodality therapies, including repeated resection and nivolumab, were considered to help her long-term survival.

[A Case of Pancreatic Metastasis from Renal Cell Carcinoma 16 Years after Left Nephrectomy].

A 73-year-old woman underwent left nephrectomy for renal cell carcinoma(RCC). The computed tomography(CT)and magnetic resonance imaging(MRI)revealed a 20-mm tumor in the pancreatic tale showing early enhancement in the arterial phase 16 years after surgery. Fluorodeoxyglucose positron emission tomography(FDG-PET)showed slightly uptake (maximum standard uptake value: SUVmax 2.3)and EUS-FNA showed a hyper-vascularized tumor in the pancreatic tail. A single pancreatic metastasis from RCC was diagnosed, and we performed distal pancreatectomy. The histopathological diagnosis was a metastatic pancreatic tumor from RCC. The postoperative course was uneventful and 1 month after surgery, she is alive with no recurrence.

[The Use of Platinum-Based Chemotherapy for Esophageal Cancer Patients with Impaired Renal Function].

INTRODUCTION: The key drugs of first-line chemotherapy for metastatic esophageal cancer are 5-FU and cisplatin(CF). However, the treatment strategy for unfit patients of CF regimen remains controversial. METHODS: Fifty patients who received first-line chemotherapy including platinum-containing drug for metastatic esophageal cancer between 2018-2022 at Osaka National Hospital were analyzed. They were divided into 4 groups according to estimated creatinine clearance(Ccr) at the beginning of the treatment; Group A(over 60 mL/min)31 patients, Group B(50-59 mL/min)12 patients, Group C(30-49 mL/min)5 patients, and Group D(under 30 mL/min)2 patients. The background and treatment outcome data of each group were retrieved retrospectively and compared. RESULTS: Group B, C, D had more elderly patients than Group A. Each Group B, C, D included 1 patient who received FOLFOX regimen. More than half patients in Group B, C, D reduced the dose of CDDP and the initial dose of CDDP was adequately reduced according to Ccr. Group B, C, D had more patients with decreased renal function over Grade 1 than Group A. The clinical response rate was Group A 65%, Group B 42%, Group C 60%, Group D 50%, respectively. There were no patients who ceased the treatment due to adverse events. CONCLUSION: Adequate dose reduction of CF regimen would become more important in the era that only CF regimen can be a partner of immune-checkpoint inhibitor.

[A Case of Radical Resection after Neoadjuvant Chemotherapy for Rectal Cancer with Pelvic Abscess].

A 66-year-old man with a history of frequent diarrhea was diagnosed with rectal cancer with obstruction and a pelvic abscess. Following a transverse colostomy, he was referred to our hospital. The initial diagnosis was rectal cancer(cT4a N1bM0, cStage Ⅲb)and a pelvic abscess due to tumor perforation. To address this condition, we performed neoadjuvant chemotherapy using a combination of 5-fluorouracil, Leucovorin, oxaliplatin, and irinotecan(FOLFOXIRI). Following 6 courses of FOLFOXIRI, the abscess disappeared and no signs of tumor progression and distant metastases were detected. Subsequently, we performed radical resection with D3LD2 lymph node dissection, leading to a pathological diagnosis of ypT3N1aM0, ypStage Ⅲb. The patient then underwent adjuvant chemotherapy with capecitabine and oxaliplatin(CAPOX). No recurrence was observed after 9 months of follow-up.

[A Case of Conversion Surgery after Chemotherapy for Unresectable Liver Metastasis of Rectal Cancer].

A 50s female was diagnosed as rectal cancer with multiple liver metastases after fecal occult blood scrutiny. Liver metastases were multiple in both lobes and involved the right Glisson's capsule. We determined that the liver metastases were unresectable and initiated FOLFOXIRI plus panitumumab treatment. After 6 courses of chemotherapy, rectal cancer resection was performed. After 12 courses of chemotherapy, the liver metastases which had extensively involved the right Glisson on imaging, shrank until the P7 root was visible. If S7 Glisson could be preserved, the radical resection was planned. If not, associated liver partition and portal vein ligation for staged hepatectomy(ALPPS)was planned. Intraoperatively, it was determined that preservation of S7 Glisson was possible and blood flow preservation in the S7 region was feasible, and an anterior segment hepatic resection(S5-6-8)and lateral segment hepatic partial resection(S2/3)were performed. She was discharged on the 18th day and has been under outpatient observation 12 months after hepatectomy.
