Prognostic significance of p16, p21, and Ki67 expression at the invasive front of colorectal cancers.

Cancer cells at the invasive front are believed to be responsible for invasion/metastasis. This has led to examining various morphological features and protein expressions at the invasive front. However, accurate assessment of the pathological section requires long-time training, and inter-observer disagreement is problematic. Immunohistochemistry and digital imaging analysis may mitigate these problems; however, the choice of which proteins to stain and the best analysis method remains controversial. We used the "go-or-grow" hypothesis to select markers with the greatest prognostic relevance. Importantly, nonproliferating cells can migrate. We used Ki67 as a proliferation marker, with p16 and p21 designating nonproliferating cells. We established a semi-automated quantification workflow to study protein expression in serial pathological sections. A total of 51 patients with completely resected colorectal cancer (stages I-IV) were analyzed, and 44 patients were followed up. Patients with cancer cells with p16-high/p21-low or p21-low/Ki67-low at the deepest invasive front demonstrated a significantly worse prognosis than those who did not display these characteristics. These results suggest that the nonproliferating cancer cells at the invasion front possess invasion/metastatic property with heterogeneity of senescence.

[A case of acalculous gangrenous cholecystitis due to artery dissection].

A 62-year-old male presented with right intercostal muscle pain. Clinical examination revealed muscular defense in the same area. Abdominal ultrasonography revealed a distended gallbladder and ascites effusion, but no gallstones or polyps were present. Contrast-enhanced computerized tomography was performed, which revealed luminal obstruction due to arterial dissection of the celiac artery and intrinsic hepatic artery. This finding suggested gangrenous cholecystitis; thus, urgent cholecystectomy was performed. Only a few cases of celiac artery dissection and only one case of gangrenous cholecystitis without stones have been reported. We report here an extremely rare case of celiac artery dissection.

Relationship between fatty liver change and nutritional status after total gastrectomy in gastric cancer patients: a retrospective study.

BACKGROUND: The relationship between chronological nutritional changes and development of fatty liver after total gastrectomy (TG) in gastric cancer (GC) patients is still unclear. This study aimed to evaluate relationship between development of fatty liver and chronological changes of nutritional parameters during 12 months after TG. METHODS: We retrospectively analyzed medical records of 59 patients with GC who underwent TG at the Kanazawa Medical University Hospital between January 2009 and December 2017. We defined fatty liver change as a mean liver-to-spleen attenuation ratio (L/S ratio) of less than 1.2 in the computed tomography images at 12 months after TG and divided the patients into fatty liver (FL) and non-FL groups from the L/S ratio. We analyzed serum levels of total protein and albumin, and psoas muscle index (PMI) before TG and at 6 and 12 months after TG in the non-FL and FL groups. RESULTS: Six patients showed an L/S ratio of less than 1.2 at 12 months after TG and were included into FL group. There was no significant difference between the groups in serum parameters, L/S ratio, and PMI before TG. In the FL group, the mean levels of total protein and albumin decreased after TG and were significant lower at 6 months, compared with the non-FL group. And then, these levels in the FL group recovered at 12 months. In contrast, the mean levels of total protein and albumin in the non-FL group did not decrease below the preoperative levels throughout the year after surgery. As with laboratory parameters, all patients in the FL group showed decrease of PMI at 6 months after TG. This proportion was significantly higher than that in the non-FL group (100% vs. 40.8%, P = 0.006). CONCLUSIONS: We evaluated that the patients with fatty liver occurring after TG had significantly lower levels of serum nutritional parameters and skeletal muscle index at 6 months, not but 12 months, after TG.

[Role of Surgical Resection after Chemoradiotherapy in Locally Advanced Pancreatic Cancer].

We investigated 34 cases of preoperative chemoradiotherapy(CRT)for locally advanced pancreatic cancer including resectable pancreatic cancer in our department during the past 11 years. For resectable(R)or borderline resectable(BR)pancreatic cancer, survival curves were generally higher in the CRT plus S-1 group treated after CRT than in the CRT group treated with post-CRT chemotherapy, but there was no statistically significant difference. In non-resected cases, local exacerbation was observed, which was one of the causes of a decline in terminal QOL. From the above, at present, it is desirable to remove R or BR pancreatic cancer after CRT, but the significance of surgery may change in the future due to the improvement of multidisciplinary treatment.

[Significance of Preoperative Chemoradiotherapy for Resectable Pancreatic Cancer].

We investigated the effect of chemoradiotherapy(CRT)on pancreatic cancer and the significance of preoperative chemoradiotherapy( NACRT)on resectable pancreatic cancer. The subjects were 36 patients who underwent CRT for locally advanced pancreatic cancer experienced in our department in the past 12 years(. 1)Regarding the antitumor effect of CRT, tumor diameter, tumor marker, and FDG for PET examination were reduced in 72%, 81%, and 96% of cases, respectively. In addition, the effect of Grade 1b plus 2 was observed in 10 of 16 patients who were resected after CRT(response rate 63%). In these successful cases, irradiation of 40 Gy or more and oral administration of S-1 1,500 mg or more were performed during this period. In addition, the survival rate of the NACRT plus S group(16 cases)was the same as that of the SF group (20 cases)of cStage ⅡA or lower at the same time, 50% survival was longer, and local recurrence was less. Based on the above, preoperative chemoradiotherapy combined with S-1 for resectable pancreatic cancer may be a promising preoperative treatment in the future.

Phase 2 study of irinotecan plus cetuximab rechallenge as third-line treatment in KRAS wild-type metastatic colorectal cancer: JACCRO CC-08.

BACKGROUND: Regorafenib or trifluridine/tipiracil as third-line treatment have limited efficacy in metastatic colorectal cancer (mCRC). METHODS: This Phase 2 trial evaluated the efficacy and safety of irinotecan plus cetuximab rechallenge as third-line treatment in KRAS wild-type mCRC patients who achieved clinical benefit with first-line cetuximab-containing therapy. The primary endpoint was 3-month progression-free survival (PFS) rate. A sample size was calculated; 30 patients with a 3-month PFS rate of 45% deemed promising and 15% unacceptable. Patients with greater and less than the cut-off value of cetuximab-free intervals (CFIs) were classified into the long and short CFI groups, respectively, in subgroup analyses. RESULTS: Among 34 eligible patients who received treatment at least once, 3-month PFS rate was 44.1% (95% confidence interval, 27.4-60.8%). The median PFS and overall survival (OS) were 2.4 and 8.2 months, respectively. The response and disease control rates were 2.9 and 55.9%, respectively. PFS and OS were significantly longer in the long- than in the short CFI group. CONCLUSIONS: Irinotecan plus cetuximab rechallenge as third-line treatment for KRAS wild-type mCRC was safe and had promising activity, especially in those with a long CFI, warranting further investigation in a Phase 3 randomised trial. CLINICAL TRIAL REGISTRATION: UMIN000010638.

The neutrophil/lymphocyte ratio as a predictor of successful conversion surgery for stage IV gastric cancer: a retrospective study.

BACKGROUND: Conversion surgery (CS) following a response to chemotherapy occasionally leads to prolonged survival in patients with stage IV gastric cancer (GC). This study aimed to evaluate the predictive value of the neutrophil/lymphocyte ratio (NLR) for the success of CS in patients with stage IV GC. METHODS: We retrospectively analyzed data of 50 patients with stage IV GC who received systemic chemotherapy between January 2009 and December 2017 at the Kanazawa Medical University Hospital. The successful CS group included the patients who underwent R0 or R1 resection with CS, and the failed CS group included the patients who did not undergo CS after chemotherapy or those who, despite undergoing CS, had to additionally undergo R2 resection. Clinicopathological characteristics were examined in both groups. Univariate and multivariate analyses were performed to identify pretherapeutic parameters that were independently associated with the achievement of successful CS. RESULTS: The number of patients in the successful and failed CS groups were 12 and 38, respectively. On univariate analysis, gender (P = 0.01), NLR (P = 0.003), albumin levels (P = 0.004), and absence of peritoneal metastasis (P = 0.004) were found to be significantly correlated with a successful CS. On multivariate analysis, NLR < 4 and absence of peritoneal metastasis were independently correlated with a successful CS (P = 0.02 and P = 0.002, respectively). In patients without peritoneal metastasis, successful CS rates in patients with NLR < 4 were significantly higher than those in patients with NLR ≥ 4 (61.1% vs. 10.0%, P = 0.005). CONCLUSIONS: The NLR was a significant independent predictor of the achievement of successful CS in stage IV GC patients, especially among the patients without peritoneal metastasis. Patients with a low NLR could have higher possibility of achieving successful CS.

Prophylactic efficacy of ninjin'yoeito for oxaliplatin-induced cumulative peripheral neuropathy in patients with colorectal cancer receiving postoperative adjuvant chemotherapy: a randomized, open-label, phase 2 trial (HOPE-2).

PURPOSE: Peripheral neuropathy (PN) is an intractable side effect of oxaliplatin, with no effective prophylaxis so far. Ninjin'yoeito (NYT), a Kampo medicine, is protective against oxaliplatin-induced neuronal cell injury in vitro and ameliorates oxaliplatin-induced PN in vivo. Thus, this randomized controlled trial was aimed at clarifying NYT's prophylactic effect for oxaliplatin-induced cumulative PN. METHODS: 52 patients with colorectal cancers of pathological stage 3 received postoperative adjuvant chemotherapy with the CapeOX regimen: eight cycles of capecitabine (2400 mg/m2) plus oxaliplatin (130 mg/m2) at 3-week intervals. They were randomly assigned to NYT administration and non-administration groups. NYT (9.0 g/day) was administered from day 1 of cycle 1 in the NYT group. The NYT was administered orally daily throughout each cycle. The primary endpoint was the grade of cumulative PN at the end of eight cycles. The secondary endpoints included relative dose intensity (RDI) of oxaliplatin, recurrence-free survival (RFS), and overall survival (OS). RESULTS: 40 patients (n = 20 in both groups) completed 8 chemotherapy cycles. The incidence of grade 2 or greater cumulative PN at the 8th chemotherapy cycle was significantly lower in the NYT group (2/20, 10.0%) than in the control group (11/20, 55.0%, P < 0.01). RDI of oxaliplatin was significantly higher in the NYT group than in the control group (P = 0.02). RFS and OS were better in the NYT group than in the control group, but the difference was not significant. CONCLUSIONS: NYT may reduce the incidence of oxaliplatin-induced cumulative PN and facilitate maintenance of the CapeOX dosing regimen.

[A Case of Effective Disease Control of Advanced Gastric Cancer with Distant Lymph Node Metastases Following Nivolumab Treatment].

A 66-year-old man was diagnosed with advanced gastric cancer(L, Less, Type 2, T4a[SE], N2, M1[LYM], H0, P0, cStage Ⅳ)and received treatment with S-1/cisplatin as first-line chemotherapy. This treatment resulted in partial response(PR) after 3 months, with reduction in the sizes of metastatic lymph nodes surrounding the pancreatic head and paraaortic lesion. However, the sizes of metastatic lymph nodes increased after 7 months of chemotherapy. Ramucirumab/nab-paclitaxel was then administered as second-line chemotherapy, and the diameter of the metastatic lymph nodes subsequently decreased after 4 months of the regimen. However, progressive disease was observed at 7 months, and blood transfusion was required because of bleeding from the primary gastric tumor. Therefore, nivolumab was initiated as third-line chemotherapy 14 months after the first treatment. After nivolumab administration, a 28% reduction in metastatic lymph nodes was achieved within 3 months, together with the regression of the primary gastric tumor and improvement in anemia within 6 months. PR was achieved after 12 months of nivolumab administration, and effective disease control was maintained for 16 months without any adverse reaction to nivolumab.

Clinicopathological significance of heterogeneic ezrin expression in poorly differentiated clusters of colorectal cancers.

Multicellular structures, such as tumor buddings and poorly differentiated clusters (PDC), exist at the invasive front of colorectal cancers (CRC). Although it has been reported that CRC with PDC showed frequent lymph node metastases with a worse prognosis, the molecular markers of PDC that are responsible for prognosis have not been identified. We here noticed for the first time that Ezrin, a regulator of the actin cytoskeleton, is expressed in the corner cells of PDC. We then aimed to verify whether heterogeneous Ezrin expression in PDC predicts the prognosis of CRC patients. We immunohistochemically analyzed Ezrin expression in PDC of 184 patients with completely resected stages I-III CRC. We established the Ezrin corner score (ECS), which quantifies the tendency of Ezrin-positive cells to accumulate at the corners of PDC. On the basis of ECS values, 2 indices, the mean ECS and the number of PDC with high ECS, were obtained. Both indices were significantly higher in CRC with lymphatic invasion, higher PDC grade, and presence of micropapillary (MP) PDC. The mean ECS-high group showed shorter recurrence-free survival than the mean ECS-low group but without significance. The other index, the number of ECS-high PDC, was significantly associated with recurrence-free survival. These results suggest that Ezrin is involved in PDC progression and lymphatic invasion, and that ECS may be a marker for aggressive PDC.

The neutrophil/lymphocyte ratio as a predictor of peritoneal metastasis during staging laparoscopy for advanced gastric cancer: a retrospective cohort analysis.

BACKGROUND: The use of staging laparoscopy (SL) has become widespread in patients with advanced gastric cancer (GC). This study aimed to evaluate the predictive value of the neutrophil/lymphocyte ratio (NLR) for the presence of peritoneal metastasis during staging laparoscopy in patients with advanced GC. METHODS: This retrospective analysis was performed in 35 patients with advanced GC who underwent SL at Kanazawa Medical University Hospital between January 2009 and December 2017. Clinicopathological characteristics were examined and multivariate analyses were performed to identify preoperative laboratory parameters that were independently associated with the presence of peritoneal metastasis or cytological malignancy (P/CY positive) during SL. RESULTS: A P/CY-positive result was confirmed during SL in 16 patients (45.7%). Patients with type 4 or diffuse type 3 tumors showed a significantly higher P/CY-positive rate than those with other tumor types (58.3% vs. 18.2%, P = 0.02). In the univariate analysis for preoperative laboratory parameters, NLR (P < 0.0001) and total protein (P = 0.03) and albumin (P = 0.04) levels were significantly correlated with a P/CY-positive result. On multivariate analysis, NLR was significantly correlated with a P/CY-positive result (P = 0.0002). In patients with type 4 or diffuse type 3 tumors, a high NLR (> 3.5) was associated with a significantly higher P/CY-positive rate than a low NLR (≤ 3.5) (83.3% vs. 33.3%, P = 0.01). Moreover, in patients without type 4 or diffuse type 3 tumors, the P/CY-positive rates were 100% and 0% in patients with NLR > 3.5 and NLR ≤ 3.5, respectively. CONCLUSIONS: The preoperative NLR was a significant independent predictor of the presence of peritoneal metastasis during SL. Regardless of tumor type, patients with a high NLR could be reasonable candidates for SL. On the other hand, non-diffuse type tumor accompanied by a low NLR may not need to undergo SL.

[A Case of Sigmoid Cancer with Six Asynchronistic Metastases to Multiple Organs That Were Resected through Four Surgeries].

A 49-year-old man underwent sigmoidectomy for the diagnosis of type 2 sigmoid cancer. Pathological findings showed a tumor 3.5×4.0cm in size, type 2, pSS, ly2, v1, pN0, cH0, cP0, cM0, pStageⅡ, R0. Asynchronistic metastases to the liver and lungs were subsequently found. Left hepatectomy was performed for 1 liver metastasis, and 4lung metastases were resected through 3 surgeries. A subcutaneous tumor in an abdominal wall scar was also resected in the 4th surgery for metastasis resection. All pathological diagnoses were metastases from sigmoid cancer, and complete curative resection was possible. The final surgery was performed 1 year and 1 month prior, and the patient has now survived without recurrence for 10 years and 2 months after sigmoidectomy. Chemotherapy was not administered during the whole course. This case shows that longterm survival is possible with repeated resection of recurrent metastasis of sigmoid cancer.

Local resection of the stomach for gastric cancer.

The local resection of the stomach is an ideal method for preventing postoperative symptoms. There are various procedures for performing local resection, such as the laparoscopic lesion lifting method, non-touch lesion lifting method, endoscopic full-thickness resection, and laparoscopic endoscopic cooperative surgery. After the invention and widespread use of endoscopic submucosal dissection, local resection has become outdated as a curative surgical technique for gastric cancer. Nevertheless, local resection of the stomach in the treatment of gastric cancer in now expected to make a comeback with the clinical use of sentinel node navigation surgery. However, there are many issues associated with local resection for gastric cancer, other than the normal indications. These include gastric deformation, functional impairment, ensuring a safe surgical margin, the possibility of inducing peritoneal dissemination, and the associated increase in the risk of metachronous gastric cancer. In view of these issues, there is a tendency to regard local resection as an investigative treatment, to be applied only in carefully selected cases. The ideal model for local resection of the stomach for gastric cancer would be a combination of endoscopic full-thickness resection of the stomach using an ESD device and hand sutured closure using a laparoscope or a surgical robot, for achieving both oncological safety and preserved functions.

[A Case of Unresectable Gastric Cancer with Multiple Metastases Responding to Chemotherapy].

A 73-year-old man presented to a clinic complaining of upper abdominal pain with nausea and diarrhea. The patient was subsequently diagnosed with progressive gastric cancer: cT4a(SE), N3M1(H1P1), Stage IV . For first-line therapy, SP: S-1(120 mg, 3 weeks)and CDDP(90 mg, 8 days iv) were selected. Though the patient had Grade 3 thrombocytopenia and renal dysfunction, 13 courses were performed over 1 year 6 months. The primary lesion in the stomach showed complete response, while the metastatic foci in the liver reduced in size. Because of renal dysfunction and thrombocytopenia, 19 courses of SOX: S-1(80 mg, 2 weeks)and oxaliplatin(100 mg, 3 weeks)were administered for 1 year. Thereafter, S-1(80 mg, 4 weeks) was continued for 6 months. Appropriate administration of chemotherapy led to complete radiographic resolution of the gastric tumor, with survival currently approaching 3 years 6 months.

[Long-Term Survival Due to Combination Therapy in a Patient with Locally Advanced Body-Tail Pancreatic Cancer].

A 49-year-old man was referred to a neighboring hospital with a chief complaint of abdominal pain.He was diagnosed with locally advanced body-tail pancreatic cancer that had invaded the celiac artery and SMA.He came to our department after undergoing radiotherapy, 2.5 Gy×22 Fr, and chemotherapy with gemcitabine(GEM)and S-1.The same chemotherapy was continued for 15 months until DIC occurred.He was subsequently treated with GEM only and then S-1 only in sequence for 6 years.We decided to stop the chemotherapy because the original lesion had been stable for a long time.After 1 month, a hard nodule appeared in the subcutaneous layer of the navel.Although resection was performed and he received chemotherapy, he died after surviving a total of 7 years and 10 months.This case is important when considering whether to discontinue chemotherapy with a stable long-term pancreatic cancer patient.

[Prognosis of Conversion Gastrectomy Cases for Stage IV Gastric Cancer].

BACKGROUND: We evaluated the efficacy of surgical resection following response to primary chemotherapy for prospective registered Stage IV gastric cancer patients. PATIENTS AND METHODS: We analyzed the details and prognosis of 6 patients having advanced gastric cancer clinically diagnosed as resectable following primary chemotherapy between 2011 and 2015. RESULTS: The reason for being diagnosed as unresectable before chemotherapy was metastasis to distant sites, including paraaortic lymph node metastasis in 3 cases, peritoneal metastasis in 2 cases, and liver metastasis in 1 case.Two patients were able to undergo R0 resection, and the remaining 4 patients were unable to undergo complete resection.The median survival time (MST)of the patients who underwent R0 resection was 567.5 days, and the MST of the patients who could not undergo R0 resection was 474 days. CONCLUSION: Careful consideration of conversion gastrectomy may be important in inducing longterm survival in clinical Stage IV gastric cancer patients.

[Remission of Advanced Gastric Cancer with Concurrent Portal Vein Tumor Thrombosis via Chemotherapy - A Case Report].

The following is a case report of moderately differentiated tubular adenocarcinoma of the stomach with widespread thrombosis of the portal vein, for which chemotherapy proved effective. A 75-year-old man presented to the clinic with a new onset ofmalaise. The patient had anemia, elevation ofliver and biliary enzymes, and significantly elevated CA19-9 levels at 43,581 U/mL and CEA levels at 2,560 ng/mL. An upper endoscopy revealed a mass lesion extending from the fundus to the pylorus as well as to the duodenum along the smaller curvature of the stomach. A biopsy revealed moderately differentiated tubular adenocarcinoma. Abdominal CT showed a mass lesion extending from the body of the stomach and penetrating through the gastric wall, and extensive lymphadenopathy in the surrounding areas. In addition, multiple thromboses were identified in the portal vein and its tributaries, including the inferior mesenteric vein, splenic vein, and intrahepatic capillaries. The patient subsequently received a single round ofS -1 and CDDP. The tumor demonstrated a marked response; the tumor size and lymphadenopathy showed a significant improvement and the CA19-9 level decreased. Because the patient's condition deteriorated, this chemotherapy regimen was discontinued. The patient was switched to S-1 monotherapy and is still alive today, 2 years 10 months after the initial diagnosis.

[Radical Resection of cT3a Gallbladder Cancer after Neoadjuvant Chemotherapy - A Case Report].

We report a case of a radical resection of cT3a gallbladder cancer after neoadjuvant chemotherapy(NAC). A 68-year-old man was referred to our hospital with a chief complaint of right hypochondralgia.Imaging findings were consistent with acute cholecystitis with a stone at the neck of the gallbladder, and advanced gallbladder cancer with infiltration into segments 4 and 5 from the fundus of the gallbladder, Gfb, cT3a(liver), cN1(8a), cM0, cStage III B, was diagnosed on staging laparoscopy. The patient received 3 courses of GEM plus CDDP NAC.The response to the treatment included reduction of the main tumor by 35%, diminished accumulation of FDG at the 8a lymph node, and decrease in serum CA19-9, from 163 U/mL to 75 U/mL. Cholecystectomy with the gallbladder bed and regional lymphadenectomy were performed.The histologic examination revealed extensive necrosis and degeneration of cancer cells in the infiltrating lesions, and the therapeutic effect was judged as Grade I b.The patient has now survived for 11 months without recurrence.

[Treatment Outcomes of Advanced Gastric Cancer after Neoadjuvant Chemotherapy with S-1 and Cisplatin].

BACKGROUND: The prognosis after neoadjuvant chemotherapy(NAC)is expected to improve in patients with resectable advanced gastric cancer who are at high risk of recurrence or those with unfavorable prognostic factors. PATIENTS AND METHODS: This retrospective study examined treatment outcomes and survival of 25 patients with advanced gastric cancer who received NAC with S-1 and cisplatin(CDDP)between October 2008 and December 2015. RESULTS: Among patients with clinical Stage II (4 patients)and III (21 patients)tumors, 13 had partial response(PR)and 12 had stable disease(SD). Neither complete response(CR)nor progressive disease(PD)was noted. CR of lymph node metastases was observed in 6 patients, PR in 9 patients, and SD in 7 patients. R0 resection was performed in 16 patients, R1 in 3 patients, and R2 in 6 patients. Histologic grades of primary tumors were Grade 0(1 patient), Grade 1a(16 patients), Grade 1b(5 patients), Grade 2(3 patients), and Grade 3(none). The 3-year survival rate after R0 resection was 46%, 3-year progression-free survival rate was 68%, and 3-year recurrence-free survival rate was 69%. Significant differences were observed for pathologic stages ypN0/1, 2, and 3(p=0.04), tumor down-stage(p=0.02), and overall tumor fStage I , II / III , and IV (p<0.01). CONCLUSION: It is conceivable that R0 resection and downstaging after NAC will improve prognosis.

[Clinical Analysis of Esophageal Bypass Surgery with Nutritional Assessment in Patients with Unresectable Esophageal Cancer].

BACKGROUND: Esophageal bypass surgery is palliative surgery for unresectable esophageal cancer with esophageal stenosis, which often leads to poor nutrition. We investigated the clinical characteristics, nutritional status, and outcomes of patients who underwent esophageal bypass surgery. PATIENTS AND METHODS: We reviewed 11 cases of esophageal bypass surgery for unresectable esophageal cancer performed in our hospital between 1992 and 2015, and we examined the surgical outcome along with preoperative nutritional assessment. RESULTS: There were 1, 9, and 1 cases of cStage Ⅲ, Ⅳa, and Ⅳb, respectively. For the bypass, a gastric tube was used in 8 cases and colon reconstruction in 3. Postoperative complications were 1 case of recurrent laryngeal nerve palsy (9%), 4 cases of anastomotic leakage (36%), and 4 cases of pneumonia (36%). The preoperative nutritional status (total protein, albumin, and cholinesterase levels) in the esophageal bypass group (n=11) was significantly worse than that in the esophagectomy group (n=40). The median survival of all patients (n=11) was 5.7 months. Patients receiving induction chemoradiotherapy followed by bypass surgery (n=7) had a median survival of 15.2 months. CONCLUSION: Since patients undergoing esophageal bypass surgery often present with malnutrition, attention to anastomotic leakage and infectious complications is necessary.
