A 72-year-old woman with past medical history of rectal cancer resection (adenocarcinoma, pT3N1aM0) presented with a 2-month history of dysphagia. Imaging studies found a thoracic esophageal cancer, for which subtotal esophagectomy with gastric conduit reconstruction via retrosternal route followed by chemoradiotherapy were performed (squamous cell carcinoma, pT4N1M0, RM1). Seven months after the esophagectomy, a contrast-enhanced computed tomography (CT) demonstrated a new asymptomatic mass inside the right atrium. A thrombus or a tumorous lesion was suspected. Positron emission tomography (PET)/CT showed abnormal uptake in the mass. After a thorough discussion by a multidisciplinary oncology group, we performed 1-week anticoagulant therapy first, resulting in mass enlargement. Then tumorectomy was carried out. The final pathological findings revealed that the mass was squamous cell carcinoma, yielding the diagnosis of cardiac metastasis from esophageal cancer. The patient's postoperative course was unremarkable. PET/CT may help to estimate malignancy and to omit invasive heart surgery.

The progressive, systemic depletion of muscle mass is a poor prognostic factor for various types of cancers. However, the assessment of body composition for patients with esophagectomy remains unclear. Therefore, we evaluated the significance of the fat-free mass index (FFMI) and estimated the appropriate cutoff value.We compiled clinicopathological characteristics of patients who underwent curative operation for esophageal cancer between October 2013 and March 2018 at Toranomon Hospital and reviewed them until December 2020. We analyzed the short- and long-term outcomes, compared to conventional nutritional factors, and calculated the area under the receiver operating characteristic (ROC) curve.A total of 200 patients were eligible for inclusion. FFMI was ineffective in predicting postoperative complications, with no correlation with other nutritional biomarkers. Preoperative low FFMI led to poor overall survival (OS), and the lower cutoff values based on the time-dependent ROC analysis were 14.4 and 16.8 kg/mThe low FFMI was not predictive of postoperative complications but an independent prognostic factor in esophageal cancer with curative resection, having no correlation with other biomarkers. Our cutoff FFMI values could be useful in selecting the target for muscle improvement programs.

We sought to evaluate the feasibility of esophageal carcinoma (EC) surgery in cases requiring dialysis. Among 250 consecutive patients undergoing surgical resection for EC, three on maintenance dialysis were identified. We retrospectively analyzed their clinical characteristics. The three dialyzed patients were all males, 39-77 years old at EC surgery. The operations were thoracoscopic esophagectomy with nodal clearance (Case 1), cervical esophageal resection without thoracic procedures (Case 2), and thoracoscopic esophagectomy without reconstruction, emergently conducted for tumor bleeding (Case 3). Reoperation had been required for postoperative abdominal hematoma in Case 1. Postoperative tracheostomy had been performed due to severe pneumonia in Case 2. EC surgery for dialyzed patients, despite appearing to be feasible, might be associated with a high risk of life-threatening morbidities. To minimize surgical risk, therapeutic decision-making for such cases should be based on the balance between radicality and safety.

There has been much debate on whether to perform TD resection in radical esophagectomy for esophageal cancer from the perspectives of metastatic rate, effect on postoperative hemodynamics, and other factors. The objective of this study was to determine whether TDLN dissection contributes to improved prognosis. This study involved 1211 patients who underwent D2/D3 dissection with TD resection for thoracic esophageal cancer between 1984 and 2020. The lymph nodes along the TD were defined as TDLNs and the remaining No. 112 nodes as non-TDLNs. The metastatic rate in TDLNs and non-TDLNs and their outcomes were compared with those of other thoracic lymph nodes. Correlation with the invasion depth of the main lesion was also analyzed (T0–2 545 patients, T3–4 666 patients). The metastatic rates in TDLNs/non-TDLNs in all patients were 7.3%/7.5%, respectively, while those in T0–2 were 2.2%/3.9%, and those in T3–4 were 11.5%/10.6%, with both having higher rates in advanced cases. The efficacy index (EI) for lymphadenectomy in T3–4 was 2.94 for TDLNs and 3.44 for non-TDLNs, with no significant difference. The metastatic rate in TDLNs by tumor site was as follows: Ut/Mt/Lt = 1.1/2.4/2.4% (T0–2) and 7.7/14.5/8.4% (T3–4), being especially high (~ 15%) in patients with advanced cases in Mt region. The EI was comparable or higher for TDLNs compared with other group-2 (Mt/Lt) and group-3 (Ut) regional lymph nodes, regardless of site. The significance of TD resection was low in T0–2 due to the low metastatic rate but became evident in cases with invasion depth of T3–4. TDLN resection was at least as effective as dissection of other group-2 or -3 lymph nodes, including No. 112 nodes.

Gastric lymphangioma (GLA) is an extremely rare tumor without an established therapeutic strategy. Surgical resection is considered the mainstay of treatment, although there is a high risk of local recurrence if negative margins are not achieved. A 51-year-old man underwent routine abdominal ultrasonography, which incidentally detected a 20-mm tumor adjacent to the lesser curvature of the stomach. GLA was suspected based on its polycystic appearance. After a 16-month monitoring period, laparoscopic resection was performed because of tumor growth and involvement of the left gastric artery. Intraoperative indocyanine green (ICG) navigation system revealed lymphatic drainage from the tumor, which we used to help determine the optimal excision line and minimize the loss of gastric volume. Pathological examination confirmed complete resection with negative margins and supported a diagnosis of lymphangioma. We performed laparoscopic radical resection of GLA under guidance from intraoperative ICG fluorescence imaging, which allowed us to maximize residual gastric volume.

Although gastric conduit cancer (GCC) arising after esophagectomy is increasingly being reported, therapeutic strategies for resectable GCC have yet to be optimized. We investigated clinicopathological features of patients undergoing endoscopic versus more invasive surgical treatments for GCC and compared their outcomes. Fifty-one patients, who had a history of esophagectomy with gastric conduit reconstruction for esophageal cancer and underwent resection for metachronous GCC, were identified. Their characteristics and outcomes were retrospectively reviewed. There were 48 males and three females, ranging in age from 46–86 years. Twelve patients underwent surgery for GCC (group S) and 39 underwent only endoscopic resection (group E). The most common cause of death was pneumonia (10/51, 19.6%). Neither overall survival nor cumulative incidence of pneumonia-caused death differed significantly between the two groups (P = 0.60, 0.84, respectively). In group S, partial gastrectomy was performed in four cases and total gastrectomy in seven. Partial resections, including three antrectomy without sternotomy or intrathoracic procedures, were completed with significantly shorter operative durations than total resections (median 208 vs 513 min, P = 0.012). GCC recurrence was experienced in two cases: one undergoing open approach partial resection of the corpus and the other thoracoscopic total gastrectomy. Even compared with endoscopic treatment, outcomes following surgery for GCC appeared to be acceptable. Open approach total gastric gastrectomy could be the most radical modality, while other less invasive alternatives, e.g., antrectomy, are also an option. Clinicians may select a treatment strategy balancing radicality and patient status, reflecting tolerance to invasive procedures.

Background and study aimsTreatment of superficial cancer in the remnant esophagus after esophagectomy is highly invasive, and early detection and minimally invasive treatment are considered necessary. We performed endoscopic submucosal dissection (ESD) for superficial cancer in the remnant esophagus and evaluated its safety and efficacy.Patients and methodsThis study involved 28 patients (33 lesions) who underwent ESD for superficial esophageal cancer in the remnant esophagus after esophagectomy from January 2007 to December 2018. The safety and efficacy of ESD were evaluated retrospectively.ResultsThe average age of all 28 cases (24 men and 4 women) was 69.6 ± 5.3 years. The average duration of ESD from esophagectomy was 2826 ± 2197 days. Twenty-six of the 28 cases were treated under general anesthesia. All 33 lesions were resected en bloc. The complete resection rate was 81.8% (27/33). There were no serious adverse events such as perforation, intraoperative bleeding, postoperative bleeding, and pneumonia. The overall survival rate was 78.6% (22/28) with a mean observation period post-ESD of 1793 ± 1148 days. There was no local recurrence, lymph node metastasis, or distant metastasis.ConclusionsThe ESD procedure for superficial cancer of the remnant esophagus was performed with high rate of complete resection without serious complications. In addition, there was no local recurrence and lymph node metastasis, and so ESD for superficial cancer of the remnant esophagus can be considered a safe and effective treatment.

Background Patients with esophageal cancer often have depressed mood and fear of metastasis and death. Esophagectomy is an invasive procedure with a high incidence of complications. The objective of this study was to examine the association between stress-coping style and psychological distress at different points in the treatment of esophageal cancer. Methods Of 152 consecutive patients treated for esophageal cancer at the outpatient clinic at Toranomon Hospital between April 2017 and April 2019, 102 met the eligibility criteria for this study. Questionnaires designed to identify psychological distress and stress-coping styles were longitudinally administered at 5 time points, from the initial outpatient consultation to 3 months after esophagectomy. Results The coping styles ‘fighting spirit’ (OR 0.836, 95% CI 0.762–0.918; p

Previous studies have evaluated the clinicopathological significance of carcinoembryonic antigen (CEA) of esophageal cancer in relatively small numbers of patients. Therefore, this study aimed to clarify the prognostic significance of CEA in 1822 patients with esophageal squamous cell carcinoma (SCC).Based on the Japanese Esophageal Society nationwide multi-institutional retrospective study, a total of 1,748 surgically treated ESCC from 15 hospitals were enrolled to evaluate prognostic impact of preoperative CEA values. Among them, 605 patients were categorized to up-front surgery group, and 1,217 patients were categorized to neoadjuvant therapy group. The CEA threshold for positivity was 3.7 ng/ml. The clinicopathological and prognostic impact of CEA was evaluated by univariate and multivariate analysis in each treatment modality groups.In total, the CEA positive rate was 25.8% (470/1822). CEA-positive status was significantly associated with distant metastasis (P = 0.004) but not associated with other factors. CEA-positive status was associated with poor overall survival (P 0.001) in univariate analysis as well as multivariate analysis (P = 0.003).CEA was an independent prognostic determinant of overall survival in esophageal SCC. Based on the subgroup analysis, regardless of the treatment modality, patients with high pretreatment CEA showed poor overall survival.

The presence of Barrett’s mucosa in the esophageal remnant is a result of post-esophagectomy anastomotic site exposure to gastric acid and is regarded as a human model of Barrett’s esophagus onset. Here, we attempted to clarify the relationship between duodenogastric reflux and formation of columnar epithelium by following the changes over time after esophagectomy. A total of 96 patients underwent esophagectomy due to superficial cancer from April 2000 to March 2018 were included in this study. Cases were divided into two groups according to the reconstruction technique after esophagectomy as either the gastric pull-up (Ga) group and ileocolonic interposition (Ic) group. Previously obtained endoscopic pictures of the cases were reviewed retrospectively and chronologically. There were 24 cases of columnar epithelium in the Ga group (42%) and 1 in the Ic group (2.6%) (P

Percutaneous endoscopic gastrostomy (PEG) is a minimally invasive procedure providing nutritional benefits to malnourished patients. Although a past history of celiotomy is not a contradiction for PEG construction, this procedure is rarely undertaken in post-esophagectomy patients, for two reasons: anatomically limited gastric spaces and high susceptibility to pulmonary aspiration. To overcome these limitations, we developed an original method of introducing PEG with jejunal extension for esophagectomized patients with retrosternal gastric pull-up reconstruction. The procedures were as follows: (1) confirmation of endoscopic transillumination of the antrum; (2) test puncture of the antral wall and subsequent gastropexy using a double-needle device; (3) insertion of a needle jejunostomy catheter into the antrum; (4) direct catheter cannulation to the pylorus and introduction of a feeding tube into the jejunum. We successfully carried out this procedure in three male patients (70-78 years old): two suffering from repetitive aspiration pneumonia and one with extensive recurrence of esophageal carcinoma. The operative times ranged 15-50 min. There were no PEG-associated complications. Of note, none of the patients experienced aspiration pneumonia after PEG construction. Our novel method appears to be a promising approach to managing esophagectomized patients because of its feasibility and the potential to prevent postoperative pulmonary aspiration.

Recurrent esophageal cancer after radical therapy usually is thought to be incurable and treated with palliative-intent systemic therapy. However, it is empirically known that surgical resection may be effective for selected patients, although no consensus exists on the efficacy of surgery for recurrent esophageal cancer. This study sought to identify a group of patients for whom surgical resection is considered effective. The study enrolled 206 patients at a single center who had recurrence after radical therapy for esophageal cancer. Prognostic factors after recurrence were identified, and efficacy of surgery was analyzed according to whether the recurrent lesions were oligometastases (i.e., ≤ 5 lesions in a single domain) or not. In the multivariate analysis, oligometastatic presentation was the only factor associated with survival after recurrence (hazard ratio 6.29; 95% confidence interval, 4.10–9.71). The actuarial survival rates for the patients with oligometastases were 59.5% at 3 years and 51.7% at 5 years. The survival rates at 3 and 5 years were significantly higher for the patients who underwent resection (64.3% and 55.6%, respectively) than for those who did not (both 100%) and for the patients with multiple metastases (9.8% and 0%, respectively). The survival rates for the patients who had oligometastases without resection were comparably lower than for the patients with multiple metastases. Oligometastatic presentation at recurrence was associated with better survival outcomes for the patients who experienced recurrence after radical treatment for esophageal cancer, and surgical resection could be a choice of treatment for this group of patients.

Diaphragmatic herniation (DH) is a rare but potentially fatal event after total gastrectomy (TG). Despite being life-threatening, risk factors for postoperative DH have yet to be elucidated. We conducted a retrospective analysis to identify clinical characteristics of patients developing DH after TG, along with a comprehensive review of the published literature. Among 1361 consecutive patients undergoing TG for esophagogastric cancer between 1985 and 2013 in Toranomon Hospital, those requiring surgical intervention for postoperative DH were included. We also conducted a PubMed literature search on DH following TG. Five patients (four males, one female), with a median age of 68 at DH surgery, were identified. Intervals between TG and DH repair ranged from 2.9 to 189.0 (median, 78.1) months. Four patients had needed emergency surgery. Three patients had undergone open TG and two others laparoscopic TG, suggesting a significantly higher incidence of DH after laparoscopic TG (3/1302 vs. 2/59, p = 0.017). The diaphragmatic crus incision, creating the space for esophagojejunostomy, had been performed in all cases. The literature yielded seven relevant publications (16 patients). Intervals between TG and DH reduction ranged from 2 days to 36 months. All operations for DH had been carried out emergently. The risk of DH persisted after TG. DH is potentially a very late complication of TG, presenting as a surgical emergency. Laparoscopic TG was suggested to be a risk factor for postgastrectomy DH. Incising the crus might also be a predictor of DH. Measures to prevent DH, e.g., appropriate closure of the crus, would be recommended in minimally invasive TG.

Background Pancreatic exocrine insufficiency (PEI) is known to occur after total gastrectomy. We experienced a case of PEI occurring 18 years after surgery, leading to a potentially fatal condition of capillary leak syndrome (CLS). Case presentation The case is a 58-year-old man on a healthy diet who underwent total gastrectomy 18 years before. He was admitted for a 3-month history of anasarca, steatorrhea, and hypoalbuminemia. An episode of fever occurred during workup, followed by pulmonary edema and shock. The patient was transferred to the intensive care unit and was started on fluid management with albumin infusion. A multidisciplinary team meeting was held, and a clinical diagnosis of PEI resulted in CLS was made and we started administration of oral pancrelipase to show clinical improvement. The patient was discharged, and he remained asymptomatic for 13 months. Conclusion In a post-gastrectomy patient with malnutrition, PEI should be suspected regardless of the period since surgery. When recognized, immediate replenishment of albumin and pancreatic enzymes should be initiated to prevent clinical deterioration.

Purpose The prognostic significance of pretreatment serum C-terminus of cytokeratin 19 (CYFRA21-1, CYFRA) status was evaluated in the patients with surgically treated esophageal squamous cell carcinoma. Methods A total of 1047 patients with surgically treated esophageal cancer were enrolled in a multi-institutional study promoted by the Japanese Esophageal Society. This study included an up-front surgery group (n = 412), a neoadjuvant chemotherapy (NAC) group (n = 486), and a neoadjuvant chemoradiation/radiation therapy (NACRT/RT) group (n = 149). The pretreatment CYFRA status was analyzed to assess prognostic significance using multivariate analysis according to treatment modalities. Results The CYFRA-positive group was significantly associated with deep tumor. Univariate analysis showed that the overall survival of the CYFRA-positive group was significantly worse than that of the CYFRA-negative group, but the difference was not significant in the multivariate analysis. CYFRA was an independent risk factor for poor prognosis just in the NACRT/RT group. Conclusions The CYFRA-positive group was associated with deep tumor and poor survival. Pretreatment CYFRA was not an independent risk factor for poor prognosis in the up-front surgery group or NAC group. It was an independent risk factor for poor prognosis just in the NACRT/RT group.

Background Although patients with positive lavage cytology (CY1) are classified as having stage IV disease, long-term survival without other unresectable factors (P0CY1) has been reported. Conversion gastrectomy in patients with a change in cytology status after induction chemotherapy might improve survival, but appropriate treatment remains controversial. Here, we reviewed our experience in treating CY1 gastric cancer to evaluate the best treatment strategy. Methods Clinical and pathological findings of patients with a diagnosis of P0CY1 gastric cancer at Toranomon Hospital between February 2006 and April 2019 were retrospectively analyzed. Patients were classified into two groups according to initial treatment: a surgery-first group and a chemotherapy-first group. In addition, the patients were categorized into subgroups based on the subsequent treatment pattern. The surgery-first group was divided into two subgroups: adjuvant chemotherapy and palliative gastrectomy only. The chemotherapy-first group was divided into three subgroups with the subsequent treatment pattern depending on the response to chemotherapy: conversion gastrectomy, palliative gastrectomy after induction therapy, and palliative chemotherapy. Results In total, 38 patients were eligible for inclusion in this study. After initial assessment of cytology status, 21 patients underwent gastrectomy as initial treatment (surgery first) and 17 received induction chemotherapy (chemotherapy first). Ten patients underwent surgery first with adjuvant chemotherapy, 11 underwent palliative gastrectomy alone, 5 underwent conversion surgery, 5 with CY1 disease after induction chemotherapy underwent palliative gastrectomy, and 7 received palliative chemotherapy only. The 3-year survival rate was 23.4% (median survival, 17.7 months) in the surgery-first group and 27.3% (median survival, 19.7 months) in the chemotherapy-first group. The 3-year survival rate was 75% for conversion gastrectomy, 16.7% for palliative chemotherapy, and 0% for palliative gastrectomy after induction chemotherapy. Conclusions There was no significant difference in outcome according to whether surgery or chemotherapy was performed first. The prognosis of conversion surgery with curative resection was better than that of the other types of treatment. However, the outlook after induction chemotherapy was poor. Patients with advanced gastric cancer should be treated cautiously until more effective treatment options become available.

Summary Background The long-term outcomes after esophagectomy for esophageal cancer remain uncertain and the optimal surveillance strategy after curative surgery remains controversial. Methods In this study, the clinicopathological characteristics of patients who underwent curative thoracic esophagectomy between 1991 and 2015 at Toranomon Hospital were retrospectively analyzed and reviewed until December 2020. We evaluated the accumulated data regarding the pattern and rates of recurrence and second malignancy. Results A total of 1054 patients were eligible for inclusion in the study. Of these, 97% were followed up for 5 years, and the outcomes after 25 years could be determined in 65.5%. Recurrence was diagnosed in 318 patients (30.2%), and the most common pattern was lymph node metastasis (n = 168, 52.8%). Recurrence was diagnosed within 1 year in 174 patients (54.7%) and within 3 years in 289 (90.9%). Second malignancy possibly occurred through the entire study period after esophagectomy even in early-stage cancer, keeping 2%–5% of the incidental risk. There was no significant difference in the prognosis between 3-year survivors with and without a second malignancy. Conclusions Most recurrences after resection of esophageal cancer occurred within 3 years regardless of disease stage. However, these patients have an ongoing risk of developing a second malignancy after esophagectomy. Further consideration is required regarding the efficacy of long-term surveillance.

BackgroundPrimary malignant melanoma of the esophagus is a rare tumor with a poor prognosis; the optimal treatment strategy has yet to be established. This study aimed to clarify clinical features, courses, and outcomes of patients undergoing surgical resection of primary malignant melanoma of the esophagus.MethodsSix patients with primary malignant melanoma of the esophagus, in whom the absence of other primary melanomas had been confirmed, were selected from the medical database maintained in Toranomon Hospital. Their clinicopathological characteristics and long-term outcomes were retrospectively reviewed and analyzed.ResultsAll 6 patients (five males and one female) underwent radical esophagectomy with three-field regional lymphadenectomy, and none received neoadjuvant therapy. Tumor invasion was classified into T1 in 5 (83%) cases and T3 in one (17%). Four (67%) patients had nodal metastases (one N1, one N2 and two N3). No distant metastatic lesions were detected preoperatively in any of our cases. Postoperative surveillance revealed recurrence in all 6 patients, and 5 (83%) died of the disease. The median overall survival was 24 months. One patient with a T3N3M0 tumor was treated after surgery with a dacarbazine-nimustine-vincristine regimen followed by irradiation for bone recurrence and survived for 87 months postoperatively. Another patient with a T1N3M0 tumor who survived for 27 months after liver and bone recurrence was treated with nivolumab, ipilimumab, and dacarbazine.ConclusionAlthough the courses of patients with primary malignant melanoma of the esophagus were consistently unfavorable, surgical resection with multidisciplinary therapeutic modalities may prolong survival in some cases.

A suitable treatment strategy for esophageal cancer after definitive chemoradiotherapy for T4 cases has not been established and remains unclear. This study aimed to clarify the independent prognostic factors, surgical indications, and optimal extent of lymphadenectomy for T4 esophageal cancer. Of 803 patients who underwent esophagectomy for esophageal cancer at the authors’ institution from 2006 to March 2018, the study included 33 patients who underwent salvage esophagectomy with locally advanced T4 cancer. The study examined the baseline attributes and treatment results of these cases and evaluated the prognostic factors and treatment strategies. The independent favorable prognostic factors in T4 cancer (T4a/T4b = 11/22) included non-T4b status [hazard ratio (HR), 15.311; 95% confidence-interval (CI), 1.277–183.5] and R0 resection (HR, 14.706; 95% CI, 1.193–166.67). For the cases in which R0 resection was possible (n = 14), both the 1- and 5-year survival rates were 90.9%, whereas for the cases without R0 dissection (n = 19), the 1- and 5-year survival rates were respectively 44.9% and 0%. In the univariate analysis, the patients who underwent two- or three-field lymph node dissection tended to have a better prognosis (p = 0.062), and those with 60 or more lymph nodes dissected had a significantly better prognosis (p = 0.038). For the patients who underwent salvage esophagectomy with typical lymph node dissection, the rate of complications classified as Clavien–Dindo grade 3 or higher (33.3%) was not increased, indicating that the procedure was relatively safe. The results showed that in salvage esophagectomy for T4 esophageal cancer, R0 resection led to improved prognosis. Because typical two- or three-field lymph node dissection including prophylactic dissection could be performed safely and led to a better prognosis in salvage esophagectomy, typical esophagectomy including prophylactic lymph node dissection should be performed if possible.

Background Pyogenic granuloma is a benign vascular tumor, usually occurring on the skin or in the oral cavity. Small intestinal pyogenic granuloma is extremely rare, but intestinal intussusception due to the tumor is even rarer. Only 3 cases have been reported in the English literature at this writing. Case presentation An 86-year-old woman presented with abdominal pain and vomiting. Laboratory data discovered anemia. Contrast-enhanced computed tomography revealed small bowel obstruction due to intestinal intussusception. After decompression by long tube for 1 week, the obstruction did not improve and the anemia got worse. Therefore, laparoscopic assisted small bowel resection was performed as a diagnostic therapy. Pathology confirmed the diagnosis of pyogenic granuloma. The postoperative course was uneventful and the patient was discharged 10 days after surgery. Conclusions We experienced a case of intestinal intussusception and progressive anemia due to pyogenic granuloma of the ileum. Although the condition is extremely rare, surgeons must take into consideration the tumor in similar cases, and complete surgical resection is required.

Background: Gastric lymphangioma (GLA) is an extremely rare tumor without an established therapeutic strategy. Surgical resection is considered the mainstay of treatment, although there is a high risk of local recurrence if negative margins are not achieved. Thus, it would be useful to develop tools and strategies to achieve safe and complete resection. We describe our experience with the first case involving GLA resection under the intraoperative guidance of indocyanine green (ICG) fluorescence imaging, which allowed us to achieve limited but complete resection with negative margins.Case Presentation: A 51-year-old Japanese man with a history of alcoholic liver disease underwent routine abdominal ultrasonography, which incidentally detected a 20-mm tumor adjacent to the lesser curvature of the stomach. The mass was suspected to be GLA based on its polycystic appearance. After a 16-month monitoring period, the patient was referred to our hospital for further assessment because of tumor growth and involvement of the left gastric artery. We selected surgical resection to facilitate a pathological diagnosis and treatment of potential invasion to the surrounding organs. Intraoperative use of a ICG navigation system revealed lymphatic drainage from the tumor, which we used to help determine the optimal excision line and minimize the loss of gastric volume. Pathological examination confirmed complete resection with negative margins and supported a diagnosis of lymphangioma.Conclusions: We performed laparoscopic radical resection of GLA under guidance from intraoperative ICG fluorescence imaging, which allowed us to maximize residual gastric volume. Although further cases are needed to validate this strategy, it may be useful for guiding the resection of GLA.

Although surgical resection is a mainstay in the management of esophageal carcinoma (EC), its postoperative outcomes remain unsatisfactory. To optimize surgical strategies for EC, a simple method of stratifying patients according to risk factors is desired. Controlling nutritional status (CONUT), the prognostic nutritional index (PNI), transthyretin and transferrin are nutritional parameters used to predict the long-term outcomes of EC patients. We aimed to comparatively evaluate the prognostic significance of these four markers, measured preoperatively, in patients with operable EC. In total, 224 patients undergoing surgical resection for EC were retrospectively reviewed. Overall/cancer-specific survivals (OS/CSS) were estimated applying the Cox proportional hazard model to univariate and multivariate analyses. PNI, transthyretin and transferrin levels were treated as continuous variables in these analyses. Preoperative CONUT had significant associations with tumor location, depth and preoperative irradiation. The other three markers all showed significant relationships with age and tumor depth. On univariate Cox regression analysis, preoperative CONUT, PNI, transthyretin and transferrin all correlated significantly with OS and CSS. On multivariate Cox regression analysis, the preoperative transthyretin level was identified as an independent predictor of OS (HR 0.51 per 10 mg/dL increase, 95% CI 0.29–0.88, p = 0.017) and CSS (HR 0.50, 95% CI 0.27–0.91, p = 0.027) as well as tumor depth, nodal metastasis and preoperative irradiation, while the other three parameters were not. Preoperative transthyretin, as a continuous variable, independently predicted both OS and CSS in resectable EC patients, appearing to be the best prognosticator among conventional nutrition-related parameters.

BackgroundEsophageal cancer patients often feel depressed and are fearful of metastasis and death. The objective of this study was to clarify the characteristics of patients with psychological distress at all 5 time points compared with patients with no psychological distress especially from standpoints of personal coping styles and QOL.MethodsIn total, 102 of 152 consecutive patients who attended the outpatient clinic at Toranomon Hospital between April 2017 and April 2019 met eligibility criteria for inclusion in this study. Questionnaires designed to identify psychological distress (HADS-scores) and assess QOL (EORTC QLQ C-30/OES18) were administered at 5 time points from the time of the first outpatient consultation to 3 months after esophagectomy. The questionnaire of coping strategies (MAC-scales) was administered at only time 1 point.ResultsBased on the trends of HADS-scores, we defined two groups: “persistent high-HAD scores” and “persistent low-HADS scores.” There are strong relationships between psychological distress and coping strategy, and psychological distress and QOL. The possibility that there are relationships between stress coping strategies and some QOL status depending on some point of treatment.ConclusionsThe psychological distress during the treatment course of esophageal cancer is significantly associated with the coping strategies and QOL influenced by esophagectomy. This study can provide baseline information for identifying patients in need of psychological management and paves the way for larger clinical studies in the future.

Aim This study aimed to clarify the prognostic factors, the advantageous factors of R0 curative resection, and optimal extents of lymph node dissection for conversion esophagectomy after induction therapy. Methods Among 1903 patients with esophageal cancer at Toranomon Hospital between January 2006 to May 2020, 151 patients with locally advanced T4b thoracic esophageal cancer were divided into two groups according to treatment: conversion surgery group (n = 54) and non‐surgical treatment group (n = 97) for comparison. Results The patients who underwent R0 curative resection showed preferable survival comparable to the survival rate of patients with cCR in the non‐surgical treatment group (1‐, 3‐ and 5‐year survival: 96.9%, 82.1% and 76.7% vs 94.1%, 86.3%, and 86.3%; P = 0.770). Multivariate analysis revealed that the T4b tumor invasion by primary site (odds ratio (OR) = 6.100; 95% CI, 1.439‐25.865: P = 0.014) and time to conversion surgery from start of induction therapy within four months (OR = 5.229; 95% CI, 1.296‐21.102: P = 0.020) were all independent advantageous factors of R0 curative resection. Actuarial 1‐, 3‐ and 5‐year survival rates in patients who underwent conversion surgery with D2‐3 lymphadenectomy were 90.9%, 48.6%, and 40.8%, respectively. Conclusions R0 resection led to improved prognosis in conversion esophagectomy for cT4b esophageal cancer. The T4b tumor invasion by primary site and time to conversion surgery from start of induction therapy within 4 months were independent advantageous factors of R0 curative resection. In addition, standard radical esophagectomy including prophylactic D2‐/3‐ lymphadenectomy should be performed if it is possible, while taking adequate care regarding the increased risk after induction therapy., In conversion esophagectomy for T4b esophageal cancer after induction therapy, R0 curative resection was found to be the most favorable prognostic factor. The T4b tumor invasion by primary site and time to conversion surgery from start of induction therapy within four months were independent advantageous factors of R0 curative resection. In addition, typical esophagectomy including prophylactic D2 or D3 lymphadenectomy should be performed if it is possible, while taking adequate care to avoid damage to the aorta and trachea.

Surveillance after curative surgery for gastric cancer is conventionally performed for 5 years. However, the appropriate follow-up period remains controversial. This study retrospectively compiled a clinicopathological database of patients who underwent curative gastrectomy between 1975 and 2010 at Toranomon Hospital and were reviewed until March 2020. Analyzing the follow-up rate and recurrence rate for each stage in each postoperative year, we set each follow-up endpoint when the subsequent recurrence rate fell below 1%. A total of 5235 patients were eligible for inclusion in the study. The rate of patients followed up for 5 years was 90.3%. The rates of follow-up were 52.7% at 10 years, 38.3% at 15 years, and 10.3% at 20 years. Recurrence was confirmed in 850 patients in total (16.2%) and in 50 patients beyond 5 years. The adequate follow-up endpoints according to stage (with

A 70-year-old man who had undergone total gastrectomy 15 years ago for mucinous gastric carcinoma on the lesser curvature of the cardia, visited our hospital complaining of cough. Chest X-ray showed a right hilar shadow and an infiltrative shadow in the left middle lung field, which was not seen in the previous year. Whole-body positron emission tomography-computed tomography (CT) revealed abnormal uptake in the irregular consolidation of the left lung, enlarged right hilar lymph nodes, and a mass lesion on the right adrenal gland. Advanced primary lung adenocarcinoma with multi-organ metastasis was suspected and a CT-guided percutaneous lung biopsy was performed. Histopathological examination showed immunostaining patterns in complete accordance with those of the resected specimen of stomach, and the diagnosis of late recurrence of gastric carcinoma was confirmed. Pulmonary metastasis might have occurred as a direct hematogenous metastasis rather than through the liver. He achieved 31 months survival after the diagnosis receiving some sequences of chemotherapy. Late recurrence over 10 years after gastrectomy is extremely rare and significant predictive factors of late recurrence are not known. We hope that this case will help in detecting significant factors predictive of late recurrence after gastrectomy for gastric carcinoma.
