RESUMEN

PURPOSE: Using a circular stapler to create an anastomosis for esophagogastrostomy after esophagectomy is well accepted; however, it remains uncertain if the greater curvature (GC) or lesser curvature (LC) of the gastric conduit is better for the anastomosis. We conducted this prospective study to compare the integrity of esophagogastrostomy between the esophagus and the GC or LC side of the gastric conduit. METHODS: The subjects of this study were 70 patients who underwent esophagectomy and were randomized to a "GC" group and an "LC" group (n = 35 each). The primary and secondary end points were anastomotic leakage (AL) and anastomotic stricture (AS), respectively. RESULTS: The overall AL rate was 22.1%, without a significant difference between the groups. Stump leakage developed in eight of nine patients in the GC group, whereas leakage developed at the esophagogastric anastomosis in five of six patients in the LC group. The rate of stump leakage was significantly higher than that of esophagogastric AL in the GC group. The overall AS rate was 4.4%, with a significant difference between the groups (0% in the GC group vs. 9.1% in the LC group). CONCLUSIONS: AL rates were comparable in the two groups, but the sites of leakage were significantly different.

RESUMEN

BACKGROUND: While chemoradiation therapy (CRT) is one of the most useful treatments for esophageal squamous cell carcinoma (ESCC), it is important to predict response prior to treatment by using markers because some patients respond well and others do not. METHODS: Fifty-nine patients with ESCC were treated with neoadjuvant CRT at the Kagoshima University Hospital. The expression of seven types of biomarker candidate proteins in biopsy specimens of untreated primary tumors was evaluated to determine whether it correlated with response and prognosis. RESULTS: The positive expression rates were 47% for p53, 83% for CDC25B, 68% for 14-3-3sigma, 76% for p53R2, 75% for ERCC1, 32% for Gli-1, and 54% for Nrf2. In terms of histological response, tumor grade of the 59 patients was 48.8% for grade 1 as the non-responder, 29.2% for grade 2, and 22.0% for grade 3 as the responder. CRT was significantly effective in p53(-), p53R2(-), ERCC1(-), and Nrf2(-) tumors, while p53(-), p53R2(-), and ERCC1(-) were factors independently correlated with effective histological response. Their combined expression of two or three negative expressions had 100% effective response and was a significant prognostic factor. CONCLUSION: Our results suggest that two or three negative expressions of p53, p53R2, and ERCC1 in biopsy specimens of primary tumors were associated with a favorable response to CRT for ESCC. Assessment of tumor suppressor and DNA repair protein expressions in biopsy specimens may be useful for the potential utility of CRT therapy for patients with ESCC prior to treatment.

RESUMEN

A 24-year-old woman was admitted to the hospital for abdominal pain. Abdominal contrast-enhanced computed tomography( CT)revealed a cystic mass measuring 11×8 cm in the left lobe of the liver with extravasation. Vascular embolization was performed, but extravasation remained on CT images. She was then transferred to our hospital. We performed an emergency extended left hepatectomy. Histopathological examination revealed solid proliferation of spindle-shaped cells. Immunohistochemical staining showed that the tumor cells were positive for vimentin and negative for AE1/AE3. Thus, a diagnosis of undifferentiated sarcoma was confirmed. Multiple recurrent tumors were recognized on CT images of the lung and right atrium taken 1 year and 10 months post-surgery. Partial resection of the tumor was performed for the right atrial mass, the left lingular segment, the left inferior lobe, and the right middle lobe. Pathological diagnosis confirmed metastasis of undifferentiated sarcoma from the liver. Chemotherapy consisting of vincristine, actinomycin D, and cyclophosphamide(VAC) was not effective, and the patient died 31 months after the primary surgery. Undifferentiated sarcoma of the liver is a rare malignant mesenchymal tumor, whose occurrence is extremely rare in adults. Although surgical treatment is the first choice, outcomes remain poor. Multimodality treatment should be used to improve the outcome.

RESUMEN

Patients with advanced esophageal squamous cell carcinoma (ESCC) is received chemoradiotherapy or chemotherapy for clinical management. However, it is difficult to predict tumor response and prognosis using blood markers before starting treatments. The purpose of this study was to investigate the pre-treatment plasma fibrinogen and neutrophil-lymphocyte ratio (NLR) in patients with advanced ESCC treated with chemoradiotherapy or chemotherapy, and to assess the clinical utility of a combined score using these blood markers, named as the F-NLR (fibrinogen and NLR) score, as a predictor of tumor response and prognosis. A total of 98 advanced ESCC patients, treated with chemoradiotherapy or chemotherapy, were classified into three groups: F-NLR score of 2, having both hyperfibrinogenemia (>400 mg/dL) and high NLR (>3.0), score of 1, one of these hematological abnormalities, and score of 0, having neither hyperfibrinogenemia nor high NLR. Fibrinogen and NLR were significantly higher in the progressive disease (PD) group than the non-PD group (P = 0.0419, and P = 0.0001, respectively). A significantly higher F-NLR score was found in the PD group than the non-PD group (P = 0.0140). Overall survival was significantly lower in patients with an F-NLR score of 2 than in those with an F-NLR score of 0 or 1 (P < 0.0001). Multivariate analysis showed that the F-NLR score was one of the independent prognostic factors (P = 0.0081). Our study demonstrates that the F-NLR score is promising as a predictive marker for therapeutic effects and prognosis in patients with advanced ESCC.

RESUMEN

BACKGROUND: Cysteine/histidine-rich 1 (CYHR1) was first discovered in a yeast two-hybrid screen with murine galectin-3, and no previous reports have described a relationship between the CYHR1 gene and human cancer. The current study evaluated the role and significance of CYHR1 in esophageal cancer. METHODS: The human esophageal squamous cell carcinoma (ESCC) cell line TE-8 and the CYHR1 knock-down cell line TE-8/small interfering (si)-CYHR1 were used for in vitro and in vivo assays. For clinical study, ESCC tissues (n = 104) were used. RESULTS: Compared with parental cells, TE-8/si-CYHR1 cells had suppressed proliferation and invasion activities. In the in vivo assay, the tumors from TE-8 cells treated with si-CYHR1 had abrogated tumorigenicity. In the clinical study, the expression of CYHR1 mRNA was associated with lymph node metastasis and stage and shown to be an independent prognostic factor. CONCLUSIONS: As the findings show, CYHR1 may represent not only a valuable prognostic marker but also a therapeutic target for ESCC patients.

RESUMEN

BACKGROUND: The impact of oral capecitabine as adjuvant chemotherapy for Japanese patients with resected colon cancer was unclear. We previously planned and conducted a prospective feasibility study (KSCC0803) and reported on the safety of oral capecitabine as adjuvant chemotherapy for Japanese patients with resected stage III colon cancer. The purpose of the current study was to assess the survival results from that study. METHODS: The study subjects were Japanese patients with resected stage III colon cancer. The protocol adjuvant regimen consisted of oral capecitabine 1250 mg/m2 twice daily on days 1-14 of a 3-week cycle for a total of eight cycles. The 3- and 5-year disease free survival (DFS) rates and overall survival (OS) rates were analyzed in the eligible cohort. RESULTS: Ninety-seven patients were registered between September 2008 and August 2009 and treated with the protocol regimen. The median follow-up time was 60.7 months. The 3- and 5-year DFS rates were 71.2% [95% confidence interval (CI): 61.7-79.8%] and 69.7% (95% CI: 59.4-77.8%), respectively. The 3- and 5-year OS rates were 92.6% (95% CI: 85.2-96.4%) and 84.5% (95% CI: 75.1-90.5%), respectively. CONCLUSIONS: The survival results in this study are in line with those of previously reported, reliable, studies. The safety and tolerability of the protocol regimen have already been confirmed. Oral capecitabine is acceptable as adjuvant chemotherapy for Japanese patients with resected stage III colon cancer.

RESUMEN

PURPOSE: To evaluate the safety and feasibility of laparoscopic complete mesocolic excision via combined medial and cranial approaches with three-dimensional visualization around the gastrocolic trunk and middle colic vessels for transverse colon cancer. METHODS: We evaluated prospectively collected data of 30 consecutive patients who underwent laparoscopic complete mesocolic excision between January 2010 and December 2015, 6 of whom we excluded, leaving 24 for the analysis. We assessed the completeness of excision, operative data, pathological findings, length of large bowel resected, complications, length of hospital stay, and oncological outcomes. RESULTS: Complete mesocolic excision completeness was graded as the mesocolic and intramesocolic planes in 21 and 3 patients, respectively. Eleven, two, eight, and three patients had T1, T2, T3, and T4a tumors, respectively; none had lymph node metastases. A mean of 18.3 lymph nodes was retrieved, and a mean of 5.4 lymph nodes was retrieved around the origin of the MCV. The mean large bowel length was 21.9 cm, operative time 274 min, intraoperative blood loss 41 mL, and length of hospital stay 15 days. There were no intraoperative and two postoperative complications. CONCLUSION: Our procedure for laparoscopic complete mesocolic excision via combined medial and cranial approaches is safe and feasible for transverse colon cancer.

RESUMEN

We report a case of acute focal bacterial nephritis(AFBN)as a complication of chemotherapy in esophageal cancer patient. A 54-year-old woman underwent thoracoscopic esophagectomy for thoracic esophageal cancer. The final pathological diagnosis was a squamous cell carcinoma, pT1b, N2(No. 110), M0, pStage II . She received adjuvant chemotherapy with docetaxel, CDDP and 5-FU(mDCF)in our hospital from February, 2016. There was no complication in first course. She visited our hospital with complaints of a fever and right flank pain on the 22 nd day after second course of chemotherapy. There was a severe inflammation reaction in the laboratory test. An enhanced CT revealed swelling and partial low density area in the right kidney. Therefore, we diagnosed AFBN, and administrated antibiotic levofloxacin for 16 days. Her symptom improved immediately, and renal function was normal when followed up 10 months later.

RESUMEN

OBJECTIVE: We assessed the clinical applicability of the F-NLR score, which is based on fibrinogen (F) and the neutrophil-lymphocyte ratio (NLR), and the Glasgow Prognostic Score (GPS) to predict the therapeutic effects of chemotherapy or chemoradiotherapy on advanced gastric cancer and the prognoses of patients. METHODS: Sixty-eight patients with advanced gastric cancer treated with first-line chemotherapy or chemoradiotherapy were classified into two groups based on tumor response. Furthermore, we categorized patients according to cutoff F-NLR scores of 2 [hyperfibrinogenemia (>400 mg/dl) and high NLR (>3.0)], 1 [one of these hematological abnormalities], and 0 [neither hyperfibrinogenemia nor high NLR]. RESULTS: A total of 27 patients had progressive disease (PD) and 41 did not. The F-NLR scores were significantly higher in the PD than in the non-PD group (p = 0.003). Survival was significantly shorter for patients with high F-NLR scores and GPS (p = 0.0071 and p = 0.0065, respectively). Multivariate analysis selected the F-NLR score as an independent prognostic factor (p = 0.017). CONCLUSION: A novel grading system based on F-NLR scores, as well as the GPS, appears to have value as a clinical predictor of the therapeutic response of advanced gastric cancer to chemotherapy or chemoradiotherapy and the prognoses of patients.

RESUMEN

PURPOSE: Therapeutic mammoplasty (TM) for breast cancer is a widely practiced oncoplastic technique. Intraductal spread towards the nipple or the location of the cancerous lesion on the central breast may become a contraindication for breast-conserving surgery. We herein report the results of TM in such cases. METHODS: Six patients underwent TM that combined partial mastectomy with free nipple-areola (NA) grafting. The nipple was removed together with the cancerous lesions, and the areola was preserved for NA reconstruction. The tumors were located in the lower quadrant (n = 1), the central area (n = 1), the upper-outer area (n = 2), and the upper-inner area (n = 2). The types of mammoplasty that were performed included: amputation (n = 1), inverted T mammoplasty (n = 3), and L mammoplasty (n = 2). With the exception of one patient, all patients underwent inverted T mammoplasty on the contralateral breast in order to achieve symmetry. RESULTS: The total surgical and plastic periods ranged from 155 to 235 min (mean 207 min) and 100 to 150 min (mean 121 min), respectively. Oncological safety and excellent cosmetic results were achieved. CONCLUSIONS: TM combining partial mastectomy with NA grafting was successfully performed in patients with early-stage cancer in all quadrant areas.

RESUMEN

A 51-year-old man who had undergone distal gastrectomy for gastric cancer was admitted in Kagoshima University Hospital under the diagnosis of anastomotic recurrence of gastric cancer. From abdominal CT results, the recurred tumor was suspected to invade into the pancreas with regional node metastases. Because of the intense radicality of surgical intervention, we planned 3 courses of docetaxel, cisplatin, and S-1 triplet therapy(DCS therapy). After the chemotherapy, the recurred tumor and lymph node metastases shrunk drastically. Segmental gastrectomy with lymph node dissection was performed with curative intent. Final pathology revealed complete regression of both the recurred tumor and lymph node metastases. The patient's postoperative course was uneventful without tumor relapse. DCS therapy seems to be suitable to obtain drastic tumor regression before surgical intervention as a neoadjuvant chemotherapy for locally advanced gastric cancer.

RESUMEN

BACKGROUND: Esophageal squamous cell carcinoma is an aggressive gastrointestinal tract cancer. To date, the presence of circulating tumor cells (CTC) has been reported as a prognostic factor in peripheral blood from patients with gastrointestinal cancers. METHODS: The CellSearch system was used to isolate and enumerate CTCs. A total of 90 patients with esophageal squamous cell carcinoma who received chemotherapy or chemoradiotherapy were enrolled. Peripheral blood specimens were collected before and after treatments. RESULTS: At baseline analysis, CTCs were detected in 25 patients (27.8 %). Overall survival was significantly shorter in patients with than without CTCs. Follow-up blood specimens were obtained from 71 patients. Partial response, stable disease, and progressive disease after treatment were seen in 32, 12, and 27 patients, respectively. CTC positivity after treatment in the progressive disease group (40.7 %) was significantly higher than that of the partial response group (6.3 %). Patients with a change in CTC status from positive to negative had a good prognosis as well as patients without baseline CTCs. CONCLUSIONS: Evaluation of CTCs may be a promising indicator for predicting tumor prognosis and the clinical efficacy of chemotherapy or chemoradiation therapy in patients with esophageal squamous cell carcinoma.

RESUMEN

BACKGROUND: Chemoradiation therapy (CRT) is one of the most useful treatments for esophageal squamous cell carcinoma (ESCC). However, because some patients respond well to CRT and others do not, it is important to be able to predict response to CRT before beginning treatment by using markers. Aurora-A encodes a cell cycle regulated serine/threonine kinase that has essential functions in centrosome maturation and chromosome segregation. In this study, we investigated the relationship between the expression of Aurora-A and the response to CRT in patients with ESCC. METHODS: We immunohistochemically investigated the expression of Aurora-A in biopsy specimens of untreated primary tumors of 78 patients with ESCC and determined the relationship between Aurora-A levels and patient responses to CRT, which consisted of 5-fluorouracil plus cisplatin and 40 Gy of radiation. RESULTS: Tumors were judged as Aurora-A positive when more than 10% of the cancer cells displayed a distinct positive nuclear anti-Aurora-A immunoreaction by immunohistochemical evaluation. The tumors of 46 of 78 patients (58.9%) displayed positive expression of Aurora-A. In terms of clinical response the percentage of patients showing complete response (CR), incomplete response/stable disease of primary lesion (IR/SD), and progressive disease (PD) was 19.2, 69.2, and 11.5%, respectively. In terms of histological response the tumor grade of the 41 patients who underwent surgery was as follows: grade 1, 48.8%; grade 2, 29.2%; grade 3, 22.0%. CRT was effective for patients who had Aurora-A (+) tumors (clinically: P = 0.0003, histologically: P = 0.036). CONCLUSIONS: Our results suggest that Aurora-A expression in biopsy specimens of primary tumors is associated with CRT efficacy in patients with ESCC. Assessment of Aurora-A expression in biopsy specimens maybe useful for regarding the potential utility of CRT therapy for patients with ESCC before treatment.

RESUMEN

BACKGROUND: The transcription factor nuclear factor (erythroid-2)-related factor 2 (Nrf2) was originally identified as a critical regulator of intracellular anti-oxidants and of phase II detoxification enzymes through its transcriptional up-regulation of many anti-oxidant response element (ARE)-containing genes. Nrf2 protects not only normal cells but also cancer cells from cellular stress, and enhances cancer cell survival. Some studies have shown that Nrf2 expression in cancer patients has clinical significance. However, there has been no comprehensive analysis of the nuclear expression level of Nrf2 in gastrointestinal cancer cells. In this study we aimed to immunohistochemically evaluate the expression of Nrf2, and to assess its clinical significance in gastric cancer. METHODS: A total of 175 gastric cancer patients who received R0 gastrectomy with standard lymph node dissection were enrolled. We immunohistochemically evaluated Nrf2 expression in the paraffin-embedded surgically resected specimens of these 175 patients. Group differences were analyzed using the χ (2) test, Fisher's exact test, and the Mann-Whitney U test. Associations between Nrf2 expression and clinicopathological features, including clinical outcome, were assessed using univariate and multivariate analyses, and Kaplan-Meier curves with the log-rank test, respectively. RESULTS: Nrf2 immunoreactivity was predominantly identified in the nucleus of gastric cancer cells. Nrf2 positivity was closely associated with tumor size, tumor depth, lymph node metastases, lymphovascular invasion, histology and stage (p < 0.05 for all). A log-rank test indicated that the overall survival of the Nrf2-positive group was significantly poorer than that of the Nrf2-negative group (p < 0.01). And, positive Nrf2 expression was significantly associated with resistance to 5FU-based adjuvant chemotherapy (p = 0.024). CONCLUSIONS: Nrf2 expression was positively associated with aggressive tumor behavior in gastric cancer. This result suggests that Nrf2 expression in gastric cancer is a potential indicator of worse prognosis.

RESUMEN

BACKGROUND: We have evaluated the safety and feasibility of combining median-to-lateral and anterior-to-median (MLAM) approaches to perform laparoscopic complete mesocolic excision (CME) with radical lymph node dissection along the gastrocolic trunk of Henle (GTH) for right hemicolon cancer. PATIENTS AND METHODS: We retrospectively analyzed data obtained from a prospectively maintained database on 31 consecutive patients who had undergone laparoscopic CME with radical lymph node dissection for right hemicolon cancer between January 2010 and December 2013. We used video recordings of the procedure to assess the quality of the surgery and completeness of CME. We also assessed operative data, pathological findings, length of large bowel resected, complications, BMI, operative time by experience of surgeon, and length of hospital stay. RESULTS: All patients had undergone en bloc resection of the enveloped parietal planes and radical lymph node dissection along the surgical trunk without any serious intraoperative complications. Twenty six and five patients graded mesocolic and intra-mesocolic plane, respectively. Five, three, eleven, and thirteen patients had T1, T2, T3, and T4 tumors, respectively. The median number of lymph nodes retrieved was 25, lymph node metastasis being identified in 11 patients. The mean length of large bowel resected was 21.8 cm. The mean operative time and intraoperative blood loss were 269 min and 39 mL, respectively. No intraoperative complications occurred in any patient. Three patients had postoperative complications. The mean BMI was 22.6 kg/m(2). The mean operative time for patients stratified by BMI of <22 or ≥22 was 225 and 297 min, respectively. There were no correlations with operative time by experience of surgeon. The median postoperative hospital stay was 13 days. CONCLUSIONS: Laparoscopic CME conducted by fusion fascia exposure with radical lymph node dissection along the GTH via a combination of MLAM approaches is a safe and feasible procedure for right hemicolon cancer.

RESUMEN

BACKGROUND: Laparoscopic colectomy has become accepted for resection of colon cancer, and laparoscopic complete mesocolic excision (CME) has proved feasible and safe. We have evaluated the safety, efficacy, and feasibility of laparoscopic CME via reduced port surgery (RPS) in patients with colon cancer. METHODS: We prospectively assessed 17 consecutive patients with colon cancer undergoing laparoscopic CME via RPS between February 2012 and January 2014. Video recordings were used to assess the quality of the surgery, including CME completion. We also assessed operative data, complications, pathological findings, visual analog scale (VAS), cosmesis, and the hospital length of stay. RESULTS: All patients underwent en bloc resection of mesocolon with CME completion. The median surgical duration and blood loss were 298 min and 41 ml, respectively. No intraoperative complications occurred in any patient. The median number of lymph nodes retrieved was 20, with lymph node metastasis identified in eight patients. The mean VAS scores for postoperative days 1, 3, and 7 were 3.2, 1.5, and 0, respectively. All patients were satisfied with their cosmesis. The median postoperative hospital stay was 11 days. CONCLUSIONS: Laparoscopic CME via RPS for colon cancer is a safe and feasible surgical procedure with cosmetic advantages.

RESUMEN

PURPOSE: Mediastinoscope-assisted transhiatal esophagectomy (MATHE) is a useful surgical procedure in esophageal cancer patients who have limited indications for transthoracic operations due to preoperative complications. METHODS: In the last 10 years, 63 patients underwent MATHE at our department. We examined the clinical data of these patients and assessed the indications, postoperative outcomes, and prognostic factors of MATHE. RESULTS: The 5-year overall survival (OS) rate was 53.4 %, and disease-free survival (DFS) rate was 66.0 %. Postoperative complications were observed in 22 cases (34.9 %), and recurrent disease occurred in 17 cases (27.0 %). On univariate analyses of OS, location of the tumor, tumor depth, lymph node metastasis, clinical stage, simultaneous resection of other organs, postoperative pneumonia, and blood loss were significant prognostic factors. On multivariate analyses, location of the tumor and lymph node metastasis were independent prognostic factors of OS. On univariate analyses, location of the tumor, tumor depth, lymph node metastasis, clinical stage, and blood loss were significant prognostic factors of DFS, while on multivariate analyses of DFS, lymph node metastasis and blood loss were independent prognostic factors. CONCLUSION: MATHE is a useful procedure for the middle to lower thoracic esophageal cancer patients without clinical lymph node metastasis with serious complications who were unable to undergo thoracotomy.

RESUMEN

BACKGROUND: We reported our experience of adenocarcinoma of sigmoid colon neovagina. CASE PRESENTATION: A 67-year-old female with a history of neovagina construction for Rokitansky syndrome complained of vaginal bleeding. She had a mucinous adenocarcinoma at the anterior aspect of the neovagina. Her original surgery, using sigmoid colon to construct the artificial vagina, was 40 years ago CONCLUSIONS: This patient's case may contribute to our understanding of carcinogenesis in the colon.

RESUMEN

A 48-year-old Japanese woman was found to have local recurrence of breast cancer in the chest wall following neoadjuvant chemotherapy, total mastectomy with axillary lymphadenectomy, postoperative radiation therapy to the chest wall, and adjuvant systemic therapy using trastuzumab. As a third line of treatment after recurrence, bevacizumab with paclitaxel was initiated for several metastatic lesions on the skin of the chest wall, left internal costal lymph nodes, and right axillary lymph nodes. The wound on the chest wall continued to expand in diameter and depth after the third course of bevacizumab with paclitaxel until the rib was exposed. After stopping the bevacizumab, granulation tissue expanded and by 3 months, had covered the bottom of the ulcer. The patient died soon thereafter, despite systemic chemotherapy with eribulin; however, there was no further bleeding from the ulcer on the chest wall or the exposed ribs.

RESUMEN

A 66-year-old man was diagnosed with synchronous early esophageal cancer and advanced gastric cancer. He received CDDP-based combination chemotherapy (docetaxcel, CDDP, and TS-1). During chemotherapy for gastric cancer, he suddenly developed septic shock, requiring intensive treatment with antibiotics, intravenous immunoglobulin, circulatory and respiratory care, and hemoperfusion with a polymyxin B column. He also had disseminated intravascular coagulation (DIC), complicated by sepsis. Recombinant human soluble thrombomodulin (rTM) was administered to treat DIC. The intensive treatments described above allowed the patient to recover from septic shock and DIC several days later. Early and adequate treatment could be used to rescue a compromised cancer-bearing patient from septic shock following chemotherapy.
