RESUMEN
BACKGROUND: A closed-loop bedside-type artificial pancreas for perioperative glucose control has previously been introduced. However, artificial pancreas therapy was often interrupted due to continuous blood sampling failure. We developed an interprofessional work manual to reduce the interruption time of artificial pancreatic therapy for perioperative blood glucose control due to continuous blood sampling failure. This study aimed to investigate the usefulness of this manual. METHODS: The manual consisted of the following sections: (1) the roles of the professionals in the preparation and management of the artificial pancreas, (2) how to address continuous blood sampling failure, and (3) checkpoints for interprofessional transfer of the artificial pancreas. We compared the results before the introduction of the manual and 2 years after the introduction of the manual. RESULTS: There were 35 and 37 patients in the Before and After groups, respectively. There were no significant differences in patient backgrounds between the two groups, although there was significantly less blood loss in the After group (1164 vs. 366 mL; p < 0.001). The mean artificial pancreas therapy and artificial pancreas therapy interruption times were 847 min and 20 min, respectively. Artificial pancreas therapy interruption time (34 vs. 8 min; p = 0.078) and time per interruption (24 vs. 4 min; p < 0.001) were significantly shorter in the After group than in the Before group. CONCLUSIONS: The interprofessional working manual was useful in reducing the artificial pancreatic therapy interruption time for perioperative glucose control.
RESUMEN
We report a very rare case of delayed necrosis of the reconstructed colon 6 months after esophagectomy.A 67-year-old male patient had undergone esophagectomy with gastric tube reconstruction for esophageal cancer in 2014. Subsequently, total gastrectomy and ileo-colon reconstruction via a retrosternal route was performed for gastric tube cancer in 2022. Six months later, he suffered acute chest pain and came to our hospital. Contrast-enhanced CT showed severe dilation of the reconstructed colon with poor enhancement of the wall opposite mesentery, without arterial obstruction. Endoscopy showed no ischemic changes in the esophago-ileum anastomosis; however, mucosal color change to black was observed in the reconstructed colon. We diagnosed ischemic colitis of the reconstructed colon and started conservative treatment; however, 18 days later, he developed a right pyothorax due to perforation of the reconstructed colon. We performed necrosed colectomy with right chest drainage and cervical esophageal fistula was made. Histopathological examination revealed mucosal detachment, thinning of the muscularis propria, and ghost-like appearance of crypt. If necrosis of the reconstructed colon is suspected in the late postoperative period, endoscopic findings of the colonic mucosa may be useful in determining surgical treatment, even in the absence of arterial blood flow obstruction.
RESUMEN
A 54-year-old woman with a mycotic superior mesenteric artery (SMA) aneurysm underwent emergent aneurysm resection with a great saphenous vein bypass. Follow-up computed tomography revealed a rapidly growing recurrent SMA aneurysm at the stump. Under the diagnosis of recurrent pseudoaneurysm of SMA with a fragile stump, we performed an open dual arterial bypass using indocyanine green fluorescence angiography and endovascular coil embolization. Subsequently, the patient's recurrent mycotic SMA aneurysm was successfully managed without mesenteric ischemic complications. This method may help prevent fatal mesenteric ischemia during SMA aneurysm surgery.
RESUMEN
Although esophageal stenting is one treatment option as a palliative treatment for tracheoesophageal fistulas, serious complications are associated with stent migration. Some reports have described stent fixation using various devices to prevent stent migration. However, these have yet to be sufficiently examined. We performed esophageal stent fixation using the MANTIS Clip (Boston Scientific), a novel re-openable endoclip. An 89-year-old man developed a tracheoesophageal fistula after radiotherapy for esophageal squamous cell carcinoma. Esophageal stenting was considered because the patient had difficulty with oral intake. However, the patient had a mild stenosis, which suggested stent migration. Therefore, we performed esophageal stent fixation by grasping the mouth side of the stent and the normal mucosa of the esophagus with the MANTIS Clip after placement of the stent. The esophageal stent closed the fistula, and the patient was able to take food orally. Upper gastrointestinal endoscopy performed 3 weeks after stenting showed residual MANTIS Clip and no evidence of stent migration. Esophageal stent fixation with MANTIS clips for tracheoesophageal fistulas may be an option to prevent stent migration.
RESUMEN
PURPOSE: Near-infrared fluorescence imaging using indocyanine green (ICG-NIFI) can visualize a blood flow in reconstructed gastric tube; however, it depends on surgeon's visual assessment. The aim of this study was to re-analyze the ICG-NIFI data by an evaluator independent from the surgeon and feasibility of creating the time-intensity curve (TIC). METHODS: We retrospectively reviewed 97 patients who underwent esophageal surgery with gastric tube reconstruction between January 2017 and November 2022. From the stored ICG videos, fluorescence intensity was examined in the four regions of interest (ROIs), which was set around the planned anastomosis site on the elevated gastric tube. After creation the TICs using the OpenCV library, we measured the intensity starting point and time constant and assessed the correlation between the anastomotic leakage. RESULTS: Postoperative leakage occurred for 12 patients. The leakage group had significantly lack of blood flow continuity between the right and left gastroepiploic arteries (75.0% vs. 22.4%; P < 0.001) and tended to have slower ICG visualization time assessed by the surgeon's eyes (40 vs. 32 s; P = 0.066). TIC could create in 65 cases. Intensity starting point at all ROIs was faster than the surgeon's assessment. The leakage group tended to have slower intensity starting point at ROI 3 compared to those in the non-leakage group (22.5 vs. 19.0 s; P = 0.087). CONCLUSION: A TIC analysis of ICG-NIFI by an independent evaluator was able to quantify the fluorescence intensity changes that the surgeon had visually determined.

The placement of a jejunostomy catheter during esophagectomy may cause postoperative bowel obstruction. The proximity of the jejunostomy site to the midline might be associated with bowel obstruction, and we have introduced laparoscopic jejunostomy (Lap-J) to reduce jejunostomy's left lateral gap. We evaluated 92 patients who underwent esophagectomy for esophageal cancer between February 2013 and August 2022 to clarify the benefits of Lap-J compared to other methods. The patients were classified into two groups according to the method of feeding catheter insertion: jejunostomy via small laparotomy (J group, n = 75), and laparoscopic jejunostomy (Lap-J group, n = 17). Surgery for bowel obstruction associated with the feeding jejunostomy catheter (BOFJ) was performed on 11 in the J group. Comparing the J and Lap-J groups, the distance between the jejunostomy and midline was significantly longer in the Lap-J group (50 mm vs. 102 mm; P < 0.001). Regarding surgery for BOFJ, the distance between the jejunostomy and midline was significantly shorter in the surgery group than in the non-surgery group (43 mm vs. 52 mm; P = 0.049). During esophagectomy, Lap-J can prevent BOFJ by placing the jejunostomy site at the left lateral position to the midline and reducing the left lateral gap of the jejunostomy.

We herein describe the rare case of a patient with a gastric duplication cyst who underwent laparoscopic resection. A 67-year-old man was referred to our hospital with an intra-abdominal lesion incidentally diagnosed on abdominal computed tomography. Esophagogastroduodenoscopy revealed normal esophageal and gastric mucosa without any lesions. Abdominal contrast-enhanced computed tomography revealed an 18 mm well-defined mass adjacent to the lesser curvature side of the esophagogastric junction. Following clinical diagnosis as an intra-abdominal mass, the patient underwent laparoscopic surgery in a five-port setting. The lesion originated from the stomach, near the muscular layer. The stomach muscle layer was partially resected; however, no communication between the mass and gastric mucosa was identified. Macroscopically, the resected specimen was 19 × 18 mm with a smooth surface and distinct margins. Microscopic examination confirmed the diagnosis of a gastric duplication cyst. The inner surface was covered with gastric gland pit-type columnar epithelial cells without atypia or neoplastic changes. The cyst wall presented layers of mucosa, muscularis mucosae, submucosa, muscularis propria, and subserosa. The patient's course after the procedure was uneventful, and he was discharged 8 days postoperatively. Gastric duplication cysts are rare and mostly asymptomatic, and their laparoscopic partial resection is safe and effective.

Recently, the results of gastric cancer treatment have improved; however, its characteristics in adolescents and young adults are not well known. We report the case of a patient with advanced gastric cancer, Fanconi anemia (FA), and primary biliary cholangitis. A 26-year-old woman visited a local physician complaining of epigastralgia. Esophagogastroduodenoscopy revealed edematous changes with poor distension and circumferential thickened folds with erosions in the gastric body. Biopsy results of the lesion specimens revealed poorly differentiated adenocarcinoma. Abdominal contrast-enhanced computed tomography revealed gastric wall with irregular thickness, several nodules in the peritoneal cavity, and a mass lesion in the right ovary. We diagnosed the patient with T4N2M1 stage IV gastric cancer accompanied by peritoneal and ovarian metastases and initiated nivolumab with S-1 plus oxaliplatin as the first-line treatment regimen. Because of immune-related adverse events after one course of systemic treatment, the regimen was changed to ramucirumab combined with nab-paclitaxel chemotherapy as the second-line treatment. After three cycles of weekly nab-paclitaxel with ramucirumab, the decreased platelet count did not recover, and her general condition gradually deteriorated. Comprehensive genome profiling using next-generation sequencing was performed to determine the feasibility of genotype-matched therapies. Alterations in FA complementation group A (FANCA) F1263del (49.1%) and E484Q (12.3%), which encode a key component of the multiprotein FA complex, were identified. The patient died 10 months after treatment initiation. In conclusion, when treating malignancies in adolescent and young adult patients, the genomic background should be considered.

Herein, we report the case of a patient with splenic hemangioma after distal gastrectomy who was treated with laparoscopic partial splenectomy. A 64-year-old woman previously underwent laparoscopic distal gastrectomy with regional lymph-node dissection for a gastric neuroendocrine tumor (G3) with venous infiltration and no lymph-node metastases. Periodic follow-up abdominal computed tomography revealed a well-defined, heterogeneous mass in the lower pole of the spleen 5 years after the operation, which grew from 12 to 19 mm 1 year later. A laparoscopic partial splenectomy was planned. During surgery, a smooth-surfaced mass with a lighter color than that of the surrounding area was observed at the lower pole of the spleen. The inferior polar branch of the splenic artery was transected, and the ischemic area of the lower pole of the spleen, where the tumor was present, was confirmed. First, the line used to perform splenic transection was determined using soft coagulation. The splenic parenchyma was then gradually transected using a vessel-sealing device system, and partial splenectomy was possible with almost no bleeding. The patient was discharged on postoperative day 8 without any complications. Pathological examination revealed a hemangioma without any malignant findings. Laparoscopic partial splenectomy is a safe and useful procedure that can be performed, considering the tumor size and location.

A 72-year-old female with type 1 diabetes, a history of interstitial pneumonia, and diabetic ketoacidosis was admitted to our hospital with dysphagia. Endoscopy revealed a circumferential neoplastic lesion in the upper to middle esophagus, and a biopsy revealed squamous cell carcinoma. Computed tomography revealed invasion of the left main bronchus, and induction chemotherapy was initiated with a diagnosis of unresectable locally advanced esophageal cancer. After one course of induction chemotherapy, the tumor size reduced, bronchial invasion improved, and thoracoscopic esophagectomy was performed. During surgery and until 3 days after surgery, the patient's blood glucose level was controlled using an artificial pancreas, and the target blood glucose range was set at 140-180 mg/dL. On the fourth postoperative day, the patient was managed using a sliding scale. Mean blood glucose was 186.7 ± 70.0 mg/dL for 3 days before surgery, 190.5 ± 25.0 mg/dL during artificial pancreas therapy from the surgery to the next day, 169.8 ± 22.0 mg/dL during artificial pancreas therapy on the second to third postoperative days, and 174.5 ± 25.0 mg/dL during sliding scale therapy for 4-15 days after surgery. No hypoglycemia or ketoacidosis was noted.
RESUMEN
We report a case of a 93-year-old woman with gastric cancer who presented with gastroduodenal intussusception and was treated with laparoscopic distal gastrectomy. Esophagogastroduodenoscopy showed a giant protruding lesion in the gastric antrum extending into the duodenal bulb, and biopsy confirmed a well-differentiated adenocarcinoma. Abdominal contrast-enhanced computed tomography (CT) revealed a well-defined mass with homogeneous enhancement and a stalk arising from the distal stomach extending into the duodenal bulb. With a clinical diagnosis of gastric cancer with gastroduodenal intussusception, the patient underwent laparoscopic distal gastrectomy with regional lymph node dissection and reconstruction using the Billroth I method. Reduction of the intussusception was performed through a 4 cm incision under the xiphoid process in the epigastric region because it could not be laparoscopically reduced. Gross examination of the resected specimen showed a well-circumscribed, elevated lesion measuring 11.2 × 4.7 × 3.6 cm in the antrum. Microscopic examination of the elevated tumor confirmed the diagnosis of well-differentiated adenocarcinoma invading the gastric submucosal layer without lymph node metastasis. There was no lymphatic or venous invasion or lymph node metastasis. The postoperative course was uneventful, and her hemoglobin level improved to 11.9 g/dL. The patient has been postoperatively well without evidence of recurrence for 3 months. Part of the superficial spreading-type tumor may be drawn into the duodenum under strong peristaltic movement because it does not infiltrate the muscle layer.

BACKGROUND/AIM: We report the case of a patient with gastric and bone metastases arising from an invasive lobular carcinoma of the breast coexisting with ductal carcinoma at the same time. CASE REPORT: A 68-year-old woman with gastric and right costal tumors was referred to our hospital. Esophagogastroduodenoscopy (EGD) revealed irregular, slightly elevated lesions extending from the gastric body to the antrum, and biopsy specimens revealed a poorly differentiated adenocarcinoma. Furthermore, abdominal contrast-enhanced computed tomography (CT) revealed extensive wall thickening with homogeneous enhancement in the stomach. 18F-2-deoxy-2-fluoro-glucose positron emission tomography (FDG-PET) showed intense FDG uptake in the right mammary gland and right third rib. Moreover, fine-needle aspiration of the third right rib lump and the right breast mass lesion was performed, and subsequent pathological investigations revealed metastatic adenocarcinoma and invasive ductal carcinoma, respectively. Immunohistochemical examination revealed that estrogen receptor was strongly positive (>95%) in breast cancer and focally positive (<5%) in gastric cancer with bone metastasis. In addition, another right breast tumor was detected by breast magnetic resonance imaging (MRI), and biopsy revealed invasive lobular carcinoma that matched the histological findings of bone and gastric lesions, including immunohistochemical examination. The patient was treated with an aromatase inhibitor, a CDK4/6 inhibitor, and a receptor activator of nuclear factor-kappa B ligand (RANKL) monoclonal antibody. She showed no symptoms or disease progression at 9-month follow-up after the initiation of systemic drug treatment. CONCLUSION: Invasive lobular carcinoma can metastasize to the gastrointestinal tract, and new treatment developments are expected as more cases will accumulate in the future.

BACKGROUND/AIM: We report a case of tracheo-esophageal fistula at a non-metastatic site during lenvatinib treatment of hepatocellular carcinoma with multiple bone metastases. CASE REPORT: A 58-year-old male patient was diagnosed with hepatocellular carcinoma with multiple bone metastases and was treated with atezolizumab-bevacizumab. However, as the bone metastasis progressed, palliative radiation therapy was administered to the third thoracic vertebra, and lenvatinib was administered as a second-line treatment. The patient was hospitalized for aspiration pneumonia five months later. Chest computed tomography and bronchoscopy revealed a 5 cm tracheoesophageal fistula located 3 cm cranial to the carina. We diagnosed a benign tracheoesophageal fistula due to lenvatinib because his previous CT scan showed no metastases at the site of the fistula, and we performed esophageal bypass surgery 4 weeks after discontinuation of the lenvatinib. CONCLUSION: To the best of our knowledge, this is the first case report of tracheoesophageal fistula at a nonmetastatic site during lenvatinib treatment for hepatocellular carcinoma.
RESUMEN
Introduction: Although it was reported that serum zinc levels were lower in patients with various malignancies, serum zinc levels of patients with gastric cancer were not well documented. Objectives: This study aimed to evaluate the association between clinicopathologic features and serum zinc levels in preoperative patients with gastric cancer. Methods: The study enrolled 83 patients scheduled for gastric cancer surgery at the Kochi Medical School. Clinical data were obtained to investigate associations between clinicopathological features, including nutritional indicators and serum zinc levels. Serum zinc deficiency was defined as serum zinc level <80 µg/dL. Results: The median zinc level of the 83 patients was 73 µg/dL (range, 20-152 µg/dL), and serum zinc deficiency was present in 66.3% of patients. Albumin was significantly lower in the zinc low level group than in the normal group (3.9 g/dL vs. 4.4 g/dL, p < 0.001), and the median serum zinc level was significantly lower in the albumin <4.1 g/dL group than in the albumin ≥4.1 g/dL group (69 µg/dL vs. 82 µg/dL, p < 0.001). Lymphocyte count was significantly lower in the zinc low level group than in the normal group (1,500 vs. 1810 years, p = 0.041). The median serum zinc level was significantly lower in the age ≥74 group than in the age <74 (71 µg/dL vs. 76 µg/dL, p = 0.002). Serum zinc levels showed a significant positive correlation with serum albumin (r = 0.637, p = 0.009). Conclusion: Serum zinc deficiency was found in 66.3% of preoperative patients with gastric cancer, which was highly correlated with serum albumin.
RESUMEN
BACKGROUND: This study aimed to determine the optimal target range of perioperative glycemic control for gastroenterological surgery. A closed-loop-type artificial pancreas (AP) was used to diminish the negative impact of hypoglycemia and glycemic variability during tight glycemic control. METHODS: In this single-center randomized trial, non-diabetic patients were assigned to tight (80-110 mg/dL) or moderate glycemic control (110-140 mg/dL) groups between August 2017 and May 2021. AP was used from the intraoperative period until discharge from the intensive care unit. The primary endpoint was the serum interleukin (IL)-6 level on the third postoperative day (3POD), and the secondary endpoints included clinical outcomes. RESULTS: Recruitment was closed before reaching the planned number of patients due to slow enrollment. Tight glycemic control (n = 62) resulted in lower mean glucose levels than moderate glycemic control (n = 66) (121.3 ± 10.8 mg/dL vs. 133.5 ± 12.0 mg/dL, p < 0.001). Insulin was administered at a 65% higher rate for tight glycemic control, achieving appropriate glucose control more than 70% of the treatment time. No hypoglycemia occurred during the AP treatment. No significant difference was observed in serum IL-6 levels on 3POD (23.4 ± 31.1 vs. 32.1 ± 131.0 pg/mL, p = 0.64), morbidity rate, surgical mortality rate, or length of hospital stay between the two groups. CONCLUSIONS: Clinically relevant short-term results did not differ, implying that 80-110 and 110-140 mg/dL are permissible glycemic control ranges when using AP in non-diabetic patients undergoing gastroenterological surgery.

We report a case of a patient with multiple diospyrobezoars, a phytobezoar attributed to persimmons (Diospyros kaki) consumption, in the stomach, who was treated with laparoscopic complete surgical excision. A 76-year-old man with gastric phytobezoars presented to our hospital. Abdominal contrast-enhanced computed tomography revealed three well-defined, oval, nonhomogeneous masses with a mottled appearance in the stomach. Esophagogastroduodenoscopy revealed three large brown solid phytobezoars and gastric ulcers at the gastric angle. The clinical diagnosis was diospyrobezoar, and, due to the huge masses, the patient eventually underwent laparoscopic treatment when the medical and endoscopic approaches were unsuccessful. After gastrotomy in the anterior wall of the stomach, the phytobezoar was mobile inside the stomach, which was opened beside the gastric incision. The three phytobezoars were removed through the wound protector using sponge-holding forceps; the hole in the gastrotomy was closed in the mucosal and seromuscular layers with an intracorporeal suture technique. The weight and size of the phytobezoars were 140 g and 115 × 55 × 50 mm, 70 g and 55 × 45 × 35 mm, and 60 g and 50 × 40 × 35 mm, respectively. The patient was discharged on the 8th postoperative day without any complications. Laparoscopic surgery to extract bezoar is the treatment of choice for this rare entity, because it is a safe and effective approach.

We describe the rare case of a patient with ureteric rupture during systemic drug treatment for peritoneal metastases of gastric cancer, who underwent double-J stent placement. A 66-year-old man with gastric cancer was referred to the authors' hospital. Esophagogastroduodenoscopy showed an irregular elevated lesion with thickened gastric folds, and biopsy specimens revealed a poorly differentiated adenocarcinoma. Abdominal contrast-enhanced computed tomography (CT) revealed extensive wall thickening with homogeneous enhancement of the stomach, enlarged lymph nodes in the perigastric area, and nodules in the peritoneal cavity, suggesting peritoneal metastases. The clinical diagnosis was cT4N2M1 with peritoneal metastases, and the patient received chemotherapy (S-1 plus oxaliplatin). After six courses of chemotherapy, the patient presented to the emergency outpatient department with a complaint of acute severe pain in the left lower back. Emergency abdominal contrast-enhanced CT showed extravasation of the contrast medium from the left upper ureter in the periureter area along with the retroperitoneum, and there was no mass lesion or stone in the kidney, ureter, or bladder. A double-J stent was placed under cystoscopic guidance, and no resistance was felt when the stent was inserted. The patient's postprocedural course was uneventful, and he received ramucirumab in combination with paclitaxel after double-J stent placement. However, 2 months later, systemic drug treatment was discontinued because of loss of appetite and increased general fatigue and changed to the best supportive care. His general condition gradually deteriorated, and he died 3 months after the ureteral rupture. Prompt interventions, including retrograde placement of ureteral stents with concurrent use of antibiotics, will reduce mortality and morbidity in this rare entity.
RESUMEN
BACKGROUND/AIM: Despite the widespread use of laparoscopic surgery, intracorporeal anastomosis remains a complicated procedure that often prolongs the operation time. This study aimed to investigate the efficacy of a novel staple line reinforcement (SLR) during laparoscopic gastrectomy for gastric cancer. PATIENTS AND METHODS: The study included 30 patients who underwent laparoscopic gastrectomy for gastric cancer at the Kochi Medical School between November 2021 and May 2022. A review of these patients was conducted, and perioperative outcomes were compared according to the use of SLR. RESULTS: The reconstruction time using SLR was significantly shorter compared to when SLR was not used (20.5 min vs. 32.0 min, p=0.048). The incidence of hemostasis during anastomosis was significantly lower in the SLR group than in the non-SLR group (0 vs. 3 times, p=0.041). There were no significant differences in the operating time and estimated blood loss after surgery between the two groups. Furthermore, there were no significant differences in postoperative complications or nutritional status between the two groups. CONCLUSION: The usefulness of SLR in reducing the time for intracorporeal reconstruction and archiving the best interaction between device and tissue during laparoscopic gastrectomy for gastric cancer, was herein demonstrated.

BACKGROUND: The purpose of this study was to compare the results of the hybrid mediastino-thoracoscopic approach with that of the conventional thoracoscopic approach and to identify the advantages and disadvantages of the hybrid approach. METHODS: We retrospectively analyzed 172 patients who underwent thoracoscopic esophagectomy for esophageal cancer from July 2009 to June 2021, excluding salvage surgery. In the mediastinoscopic approach, the lymph nodes were dissected from a small incision in the left aspect of the neck to the aortic arch with supine double-lung ventilation. Thereafter, the middle-to-lower mediastinum and right superior mediastinum were dissected thoracoscopically in the prone position. The patients' demographics, surgical outcomes, postoperative complications, and postoperative recurrence patterns were compared between 51 patients in the hybrid approach and 121 patients in the conventional approach. RESULTS: The hybrid group had more elderly patients (71 years vs. 67 years; P = 0.010), more cardiovascular disease (33.3% vs. 16.7%; P = 0.021), lower rates of preoperative chemotherapy (49.0% vs. 69.4%; P = 0.015), and shorter right lung collapse time (196 min vs. 264 min; P < 0.001). Postoperative hoarseness was not different between the two groups (31.4% vs. 27.3%; P = 0.584), and there was a significant difference in the sternal-vertebral distance at the level of the sternal notch (41 mm in the hybrid group vs. 48 mm in the conventional group; P = 0.029). The sternal-vertebral distance of less than 45 mm was an independent risk factor for postoperative hoarseness in the logistic analysis (odds ratio 3.636, 95% confidence interval 1.054-12.546; P = 0.041). CONCLUSION: The hybrid mediastino-thoracoscopic approach could be safely adapted to elderly or cardiopulmonary diseased patients; however, short sternal-vertebral distance might be a risk factor of postoperative recurrent laryngeal nerve palsy.

BACKGROUND: In Japan, nivolumab administration is the standard treatment for patients with unresectable advanced or recurrent esophageal squamous cell carcinoma (ESCC) who are refractory or intolerant to fluoropyrimidines and platinum-based chemotherapy. We determined if inflammatory prognostic factors are useful in patients with ESCC treated with nivolumab monotherapy. METHODS: The clinical data of patients with ESCC treated with nivolumab monotherapy as the second- or later-line treatment were retrospectively analyzed. Neutrophil/lymphocyte, platelet/lymphocyte, and C-reactive protein/albumin ratios (CAR); prognostic index; and prognostic nutritional index were investigated. Cut-off values for each factor were determined according to overall survival using time-dependent receiver operating characteristic curves. RESULTS: During January 2017-June 2021, 93 consecutive patients with ESCC were enrolled from five institutions (median age, 70 years; male, 77%). With a median follow-up period of 9.1 (range, 1.0-34.7) months, the median overall and progression-free survival were 12.8 (95% confidence interval [CI], 9.0-16.6) and 4.0 (95% CI, 2.6-5.4) months, respectively. Of five inflammatory prognostic factors, the cut-off value for CAR was 0.62; prognosis was significantly longer in those with CAR < 0.62 (hazard ratio, 0.39; 95% CI, 0.22-0.67; p = 0.001). CONCLUSIONS: Inflammatory prognostic factors were useful in predicting prognosis for ESCC patients pretreated with nivolumab, especially for those with CAR < 0.62, suggesting that CAR adequately reflects prognosis.
