RESUMEN
BACKGROUND: The esophagus has no serosa; therefore, esophageal cancer may quickly invade its adjacent organs. In recent years, reports of conversion surgery (CS) and salvage surgery (SS) have described resection of esophageal cancer previously considered unresectable, with the addition of intensive preoperative chemotherapy or chemoradiotherapy. Currently, there is no established method for determining whether tumor excision is possible. Additionally, differences in surgical approaches between facilities may influence outcome after resection. However, the option for resection is considered a significant factor in determining a patient's prognosis. METHODS: Patients who were diagnosed with advanced-stage (T3 or higher) squamous cell carcinoma of the esophagus and subsequently underwent resection with CS or SS were included in the study. Resection was performed through a small thoracotomy using a thoracoscope. Clinicopathologic factors, such as complete resection rate (R0) and prognosis, were investigated. RESULTS: A total of 49 surgeries were conducted: 39 CS and 10 SS cases. The male-to-female ratio was 37:12. R0:R1:R2 equals 42:3:4, and the R0 resection rate was 85.7%. The 5-year survival rates for CS and SS cases were 69.2% and 32.1%, respectively. The 5-year survival rates for R0, R1, and R2 resections were 63.4%, 0.0%, and 25.0%, and those for R0 and R1 + 2 resections were 63.4% and 14.3%, respectively, indicating that the prognosis for R0 resection cases was significantly better (P = 0.001 and P = 0.001, respectively). Regarding chemotherapy for CS, 29 patients received 5-FU and cisplatin therapy, whereas 10 patients received 5-FU, cisplatin, and docetaxel (DCF) therapy. After 2015, the ratio of DCF was significantly high, and the R0 resection rate was 100% in patients who received DCF therapy. CONCLUSIONS: In this study, a satisfactory R0 rate was achieved using the magnifying effect of the thoracoscope while ensuring safety during thoracotomy. TRIAL REGISTRATION: This was a single-center cohort study wherein clinical data were retrospectively registered. This study was approved by the Chiba Cancer Center review board (H29-262). All procedures adhered to the ethical standards of the responsible committee on human experimentation and the Helsinki Declaration of 1964 and its later amendments.

We verified the significance of intestinal blood flow evaluation by indocyanine green(ICG)fluorescence during intracorporeal anastomosis in laparoscopic colectomy which was performed from July 2019 to December 2019 in our institute. For 11 cases of intracorporeal anastomosis, we examined the patient background, surgical results such as operation time and blood loss, evaluation of intraoperative ICG blood flow, and perioperative complications. In all cases, after the mesentery treatment in the abdominal cavity and before the intestinal incision, the blood flow of the planned anastomosis site was evaluated by ICG fluorescence observation. No cases were required to be changed the anastomosis site. The average operation time was 240 minutes and the average blood loss was 10 mL. There were no perioperative complications such as anastomotic leakage, stenosis, bleeding, nor wound infection. It was suggested that the intraoperative evaluation of ICG blood flow during intracorporeal anastomosis in laparoscopic colectomy may contribute to the suppression of complications such as anastomotic leakage.

There are few reports on laparoscopic stoma creation; we report here our experience with laparoscopic stoma creation. PATIENTS AND METHODS: Seven patients who underwent laparoscopic stoma creation between April 2019 and December 2019 were studied and their clinical outcome was evaluated retrospectively. Operation approach: We performed a colostomy in the transverse colon. At first, we insert a 12 mm first port into the site of stoma marking. And more, we insert three 5 mm ports on the opposite side of the first port. We remove the adhesions of the intestinal tract and create a colostomy. RESULT: We changed open method 2 cases out of 7 cases due to extensive adhesion. In laparoscopically, we had an operation time of 97 (42-130) minutes and a blood loss of 5(2-40) mL. We had no postoperative complications or stoma problems. CONCLUSION: Laparoscopic stoma creation was useful due to few postoperative complications and can be rapidly transferred to chemotherapy.

We report a case of transverse colon cancer resected by laparoscopic partial colectomy, followed by open gastrectomy. A man in his 70s was diagnosed with transverse colon cancer. He had a history of open gastrectomy for gastric lymphoma; thus, postoperative adhesions were expected in the upper abdomen. We performed a laparoscopic partial colectomy with gentle adhesiotomy, without injury. After preparation of the marginal vessels, blood flow towards the planned anastomotic line was confirmed by infrared observation after venous injection of indocyanine green. However, the initially planned oral anastomotic line did not show a blood supply; therefore, the anastomotic line was altered to a site of sufficient blood flow. In postlaparotomy cases, delicate handling and careful adhesiotomy are necessary in the laparoscopic approach due to the possibility of severe intraoperative injury resulting in conversion to open surgery. Furthermore, blood flow confirmation by fluorescence angiography is recommended in cases in which anatomical alterations might have occurred due to the previous operation.

Neoadjuvant chemotherapy has been performed for locally advanced colorectal cancer with invasion to other organs or lateral lymph node metastasis in to control local recurrence and distant metastasis. We evaluated the treatment results and the significance of surgery in 53 patients(36 rectal cancer cases and 17 sigmoid colon cancer cases)who underwent surgery after chemotherapy by XELOX plus bevacizumab for 3 months. As pretreatment diagnosis, 42 cases were T4b and 39 cases were lymph node positive. Combined resection was performed in 34 cases including 12 cases of total pelvic exenteration. Pathological diagnosis showed 27 cases of ypT4b and 34 cases of ypN0. Pathological curative resection was performed in 90.4%. Histological effect by chemotherapy was 31 cases in Grade(Gr)1a, 10 cases in Gr 1b, 8 cases in Gr 2, and 4 cases in Gr 3, respectively. The 5-year survival rate was 60.9% in Gr 1a or lower and 100% in Gr 1b or higher. Tumor markers( CEA and CA19-9)were reduced into normal range after neoadjuvant chemotherapy in all 4 patients with Gr 3. Pathological CR could not be predicted from clinical findings after neoadjuvant chemotherapy. It was suggested that neoadjuvant chemotherapy for locally advanced rectal cancer with invasion to other organs or lateral lymph node metastasis is useful for improving the prognosis, surgical resection is indispensable as a multidisciplinary treatment, and that the pathological therapeutic effect leads to prognosis prediction.

BACKGROUND: The number of patients with esophagogastric junction (EGJ) cancers has tended to increase. However, no clear consensus on the optimum treatment policy has yet been reached. METHODS: This study included patients diagnosed with adenocarcinoma of Sievert type II in whom resection was performed in our hospital. We performed a clinicopathological examination, and patients were divided into two groups by the tumor size: L group, tumor size ≥4 cm; and S group, tumor size < 4 cm. The clinical factors, such as nodal dissection and recurrence pattern, were then analyzed. RESULTS: A total of 48 patients were diagnosed with ECJ cancers. The average tumor size was 55.1 mm, and 32 cases (66.7%) had tumors ≥4 cm. Metastasis to the mediastinum was noted in 4 cases (12.5%) in the L group but none in the S group. Recurrence in the upper or middle mediastinum lymph nodes was noted in 3 cases (9.4%) in the L group. The 5-year overall survival rates were 49.7 and 83.9% in the L and S groups, respectively. CONCLUSIONS: As the tumor grows large, it is difficult to accurately judge EGJ on the image, and as a result it is difficult to understand the exact esophageal invasion distance of the tumor. Therefore, lymph node dissection including the upper mediastinum is considered vital, regardless of the degree of esophageal invasion.

Neoadjuvant chemotherapy(NAC)with S-1 plus CDDP(SP)followed by gastrectomy has been used for the treatment of patients with locally advanced gastric cancer. We examined the number of treatment courses, histologic effects, ypStage, and prognosis to estimate the utility and define the best treatment course of SP NAC. The patients were divided into 1 course(A: 54 cases), 2 courses(B: 50 cases), and incomplete first course(C: 12 cases). The rates of Grade 2 or more in histological effect were 24.1% in group A, 34.0% in B, and 0% in C. Four patients achieved pathological CR(1 case in group A and 3 cases in group B). The pathological response by NAC was more effective in group B than in group A. In down-staging cases by NAC, survival curves were obtained according to ypStage. The 5-year survival rates in R0 cases were 67.0%in the effective therapeutic group and 51.0%in the non-effective group; the results being significantly different. According to the number of therapeutic courses of NAC, the 5-year survival rates were 57.9% in group A, 65.2% in group B, and 20.0% in group C, demonstrating a significantly better prognosis in group B. Although the pathological response appeared in 1 course, it was significant in 2 courses of NAC. The results indicate that the completion of at least 2 courses of NAC are necessary in locally advanced gastric cancer.

We report a case of synchronous cancer of the kidney and ascending colon that was resected concurrently using roboticassisted partialnephrectomy and laparoscopic ileocecalresection. A man in his 70s was diagnosed as having renaland ascending colon cancers. Thus, simultaneous resection was planned. First, robotic partial nephrectomy was performed via a transabdominalapproach by the urologicalsurgeon. After changing the position from semi-lateraldecubitus to supine, severalports were added and laparoscopic ileocecal resection was performed. Robotic and laparoscopic surgery was performed simultaneously, and the benefits of minimally invasive surgery were obtained.

With the aging population, the number ofearly gastric cancer patients aged 80 years or older is increasing. We clarified the outcome ofgastrectomy among early gastric cancer patients aged 80 years or older and examined the significance ofadditional gastrectomy for non-curative ESD cases. 1 ) Surgical outcomes in 90 cases ofearly gastric cancer patients aged 80 years or older with gastrectomy were analyzed. Gastrectomy was performed for patients up to 88 years of age and 84 cases (93.3%)were pStageâ A. Three years and 5 years survival rates were 83.9% and 60.4%, respectively. The causes ofdeath included other disease in 28 cases, other cancer in 4 cases, and death associated with hospital stay in 1 case. 2 ) There were 28 non-curative ESD cases, including 6 T1a, 9 T1b1, and 13 T1b2. Among them, 8 additional gastrectomies were performed, but none were lymph node metastases and cancer residue at the proper muscle layer was identified in only 1 case. Three years and 5 years survival rates ofthe additional gastrectomy group were 100% and 60%, respectively. Although 2 years survival rate ofthe group without additional gastrectomy was 83.3%, there were no deaths due to gastric cancer. In elderly patients with early gastric cancer, considering the increasing the proportion deaths due to other diseases and the decreased quality of life after gastrectomy, the usefulness of additional gastrectomy for non-curative ESD is limited.

BACKGROUND: Although serum p53 autoantibodies (s-p53-Abs) are induced even in the early stages of colorectal cancer, their positive rate is only approximately 20%. Therefore, we assessed the possibility of using other serum autoantibodies to increase the positive rates for detecting colorectal cancer. METHODS: Autoantibodies against 17 tumor antigens (p53, RalA, HSP70, Galectin1, KM-HN-1, NY-ESO-1, p90, Sui1, HSP40, CyclinB1, HCC-22-5, c-myc, PrxVI, VEGF, HCA25a, p62, and Annexin II) were evaluated in 279 patients with colorectal cancer and 74 healthy controls. Cutoff values were fixed at mean + 3 standard deviations of serum titers in healthy controls. RESULTS: Autoantibodies with the highest positive rates were p53 (20%), RalA (14%), HSP70 (12%), and Galectin1 (11%). Combination assays using multiple autoantibodies increased the positive rates based on the number of autoantibodies used. Positive rates of 56, 62, 66, 71, and 73% were obtained with 6, 9, 11, 14, and 17 antibodies, respectively, for the overall disease. Moreover, these autoantibodies showed relatively high positive rates even during stage 0/I disease (55 and 70% with 6 and 17 antibodies, respectively). CONCLUSION: The measurement of set of 17 autoantibodies allowed autoantibody profiling in patients with colorectal cancer. The combination assay of six tumor antigens (p53, RalA, HSP70, Galectin1, KM-HN-1, and NY-ESO-1) achieved a positive rate of 56%. Such high positive rates will be helpful for detecting colorectal cancer regardless of tumor stages.

Preoperative chemotherapy has been performed for locally advanced colorectal cancer, to achieve cytoreduction, local control, and prevention of distant metastasis. The regimens of mFOLFOX6/XELOX plus bevacizumab for 3 months have been adopted to succeed curative resection for borderline resectable colorectal cancer. We examined treatment results for locally advanced colorectal cancer without distant metastasis. Thirty-four patients were examined and the mean age was 62.7 years old. The cohort comprised of 23 cases of rectal cancer and 11 of sigmoid colon cancer. Thirty cases were diagnosed as cT4b and 25 cases were as cN+before chemotherapy. Stoma creations were performed in 26 patients before preoperative chemotherapy. Reduction ratio of the tumor diameter was 33.6±28.2%. The reduction in CEA was 38.5±39.4%, and the reduction in CA19-9 was 62.8±42.3%. There were 23 extended resections combined with involved organs including 8 total pelvic exenterations. Chemotherapeutic effect was diagnosed as Grade 1a or less, 20 cases; Grade 1b, 6 cases; Grade 2, 5 cases; Grade 3, 3 cases. Recurrence was found in 9 cases and 8 of them were Grade 1a or less. Overall 5-year survival rate was 74.6%. The utility of preoperative chemotherapy for locally advanced rectal cancer is suggested not only for local treatment but also systemic therapy, especially in chemotherapeutic effective cases.

We report a case of locally advanced rectal cancer invading toward sacrum treated by laparoscopic low anterior resection. A man in his 60's was diagnosed with rectal cancer expanding near to sacrum. The circumferential resection margin was assessed to be scarce. After preoperative chemotherapy, we performed laparoscopic low anterior resection. In order to obtain surgical margin, we had to cut into presacral venous plexus. With prepared sufficient devices, hemostasis was safely acquired. Pathological findings revealed clear surgical margin. It is important to prepare appropriate hemostasis devices in managing cases with high risks of intraoperative hemorrhage. Laparoscopic approach may contribute to these cases, making hemostasis easier than laparotomy with the magnified view, pneumoperitoneum and Trendelenburg position.

We report a case of mucinous adenocarcinoma of the appendix with peritoneal dissemination diagnosed by laparoscopic abdominal exploration and appendectomy. A man in his 60's was diagnosed with peritoneal dissemination of mucinous adenocarcinoma incidentally during an operation for an inguinal hernia. Carcinoma of the appendix was suspected as the primary lesion after further examination. We performed laparoscopic abdominal exploration and appendectomy. The purpose of the operation was to detect the primary lesion, make a pathological diagnosis, and to evaluate the extent of peritoneal dissemination. Laparoscopic findings revealed wide spread peritoneal dissemination and the pathological findings confirmed mucinous adenocarcinoma of the appendix. These laparoscopic procedures lead to a precise diagnosis and allowed for adequate treatment selection.

This study aimed to survey treatment ofgastric cancer via gastrectomy or endoscopic submucosal dissection(ESD)in patients aged 85 years or older and to clarify the risks and benefits of gastrectomy in terms of postoperative complications and prognosis. The analysis included 40 patients who were treated via gastrectomy and 41 who were treated via ESD. All patients were aged 85 years or older. Although most ofthe patients who had gastrectomy had good performance status(PS), comorbidities were found in 72.5%, and limited operation was often performed. In the gastrectomy group, R0 tumor-free resection margins were achieved in 75%, and postoperative complications occurred in 45%. Despite R0 surgery, the 2-year overall survival rate was 61.7% and the 3-year overall survival was 42.9%. Seven patients(17.1%)in the ESD group were diagnosed with T1b tumors, and no patients were shifted to surgery. Treatment decisions for super-elderly gastric cancer patients are made with regard to age, PS, and comorbidities. There is a limit to survival time after radical gastrectomy. It is necessary to examine the negative effect of gastrectomy on survival time. Selected patients aged 85 years or older with T1b gastric cancer should be given the option of ESD.

A 78-year-old man presented with a chief complaint of dysphagia. He was diagnosed with an esophageal squamous cell carcinoma and referred to our hospital. A type 3 tumor was identified in the lower thoracic esophagus on endoscopy. A CT scan revealed lymph node metastases at the No. 3 station. The clinical stage of the tumor was T3N1M0, Stage III. The patient was treated with neoadjuvant chemotherapy consisting of2 courses of5 -FU and nedaplatin. He had a partial response and underwent a radical esophagectomy. Histopathological examination revealed a complete response of the primary lesion and viable cancer cells in only one lymph node at the No. 3 station. No adjuvant chemotherapy was administered. Three months after the operation, recurrences in the upper abdominal multiple para-aortic lymph nodes were detected. Although he was treated with chemotherapy, he died 7 months after the operation. Even after a complete response of the primary lesion was achieved using neoadjuvant chemotherapy, esophageal cancer with lymph node metastasis has the potential for an early recurrence. Therefore, we should consider adjuvant therapy in such cases.

We report a case of anal canal cancer with inguinal lymph node metastasis treated with laparoscopic abdominoperineal resection combined with inguinal lymph node dissection. A 52-year-old woman was diagnosed with anal squamous carcinoma after excision of an anal canal tumor. Further examination revealed right inguinal lymph node metastasis. Chemoradiotherapy was administered but was discontinued because of serious adverse events. We therefore performed laparoscopic abdominoperineal resection combined with inguinal lymph node dissection. The pathological findings revealed residual squamous cell carcinoma at the lymphatic vessels in the rectal wall and lymph nodes, including the right inguinal region. Therapeutic effect of Grade 1a was achieved in spite of interruption of the chemoradiotherapy. She was discharged 17 days after the operation, and no recurrence was observed for 11 months. Radical resection was performed for the anal canal squamous cell carcinoma with the metastasis to the right inguinal lymph node, even after interruption of the chemoradiotherapy.

We monitored serum p53 antibody (s-p53-Ab) titers in a 76-year-old man with esophageal adenocarcinoma, clinical stage III (T2N2M0), for over 4 years, including during the perioperative period and throughout follow-up after surgery. Screening tests for CA19-9 (205 IU/ml) and s-p53-Abs (381 U/ml) were positive before treatment. After neoadjuvant chemotherapy with 5-FU and cisplatin, CA19-9 decreased to the normal range, but the s-p53-Ab titer remained positive (224 U/ml). Pathological findings of surgically resected specimens showed stage T1b disease and no lymph node metastases. After surgery, s-p53-Ab titers consistently decreased, with no disease recurrence. Although the s-p53-Ab titer remained positive even after 4 years, it decreased to 8.66, 3.59, 2.38, and 1.92 U/ml, 1, 2, 3, and 4 years after surgery, respectively. Thus, monitoring perioperative changes in s-p53-Ab titers proved useful for detecting the presence of residual cancer cells in a patient with superficial esophageal adenocarcinoma.

We evaluated the efficacy of intraperitoneal chemotherapy with cisplatin (CDDP) for peritoneal recurrent gastric cancer following surgical intervention. Twelve patients were enrolled. The combination systemic chemotherapy was S-1 or S-1 plus paclitaxel (S-1+PTX). PTX was administered intravenously at 80 mg/m² on day S-1 and 15. S-1 was administered at 80 mg/ m²/ day for 7 consecutive days, followed by 7 days of rest, and the cycle was repeated. CDDP was administered intraperitoneally at 40 mg/body on day 8. This treatment was repeated every 4 weeks until disease progression was diagnosed. The survival time(ST)and time to treatment failure(TTF)were estimated. The surgical interventions were gastrectomy in 3 patients, colostomy in 8 patients, and enterostomy in 1 patient. Overall, the median TTF and ST were 294 days and 455 days, respectively. When stratified by surgical method and combination chemotherapy, the median TTF and ST were not statistically significant. However, when stratified by performance status (PS), the median TTF was 352 days for patients with PS 0 and 218 days for those with PS 1, 2 (p=0.0029), whereas the median ST was 553 days for patients with PS 0 and 331 days for those with PS 1, 2 (p=0.0198). In conclusion, the data suggest that intraperitoneal CDDP chemotherapy with systemic chemotherapy is effective for the treatment of extensive peritoneal recurrent gastric cancer, especially in patients with good PS.

Uncertainty exists about whether elderly patients benefit to the same extent as younger patients from the chemotherapy for colorectal cancer. Patients older than 75 years of age are usually excluded from metastatic colorectal cancer randomized studies. Some subset analyses with comparison of younger and elderly patients from these pooled data revealed the significance of the chemotherapy for elderly colorectal cancer patients. This article introduces the review of these subset analyses and JCOG1018 trial which is on-going study to clarify the efficacy of oxaliplatin combination first line chemotherapy for elderly metastatic colorectal cancer patients.

Background: Critical upper airway obstruction, hematoma formation, and recurrent laryngeal nerve palsy have been reported as postoperative complications of thyroid surgery. Although remimazolam may reduce the risk of these complications, the efficacy of flumazenil with remimazolam has not been reported. We present the successful anesthesia management of thyroid surgery using remimazolam and flumazenil. Case Presentation. A 72-year-old woman was diagnosed with a goiter and scheduled for a partial thyroidectomy under general anesthesia. We used remimazolam for induction and maintenance using a neural integrity monitor, electromyogram, and endotracheal tube under the bispectral index monitor. At the end of the surgery, spontaneous respiration was confirmed after the intravenous administration of sugammadex, and the patient was extubated under mild sedation. In the operating room, we administered flumazenil intravenously to confirm recurrent laryngeal nerve palsy and active postoperative hemorrhage. The patient was confirmed to have no recurrent laryngeal nerve palsy under full wakefulness but developed active postoperative hemorrhage with normal blood pressure. The patient required reoperation and was reintubated under intravenous administration of propofol. The anesthesia was maintained using 5% of desflurane, and the patient was extubated without any postoperative problems. The anesthesia was then terminated. The patient had no recall of the procedure. Conclusion: Maintenance of general anesthesia using remimazolam allowed the use of a neurostimulator with minimal muscle-relaxant effects, and extubation under sedation reduced the risk of abrupt and unexpected changes in blood pressure, body movement, and coughing. Furthermore, after extubation, the patient was rendered fully awake using flumazenil to confirm the presence of recurrent laryngeal nerve palsy and active postoperative hemorrhage. In addition, the patient had no memory of the reoperation, suggesting that the anterograde amnesic effect of remimazolam had a favorable psychological outcome associated with the reoperation. We safely managed thyroid surgery using remimazolam and flumazenil.
