[A Case of Advanced Gastric Cancer with Multiple Bone Metastases, Virchow Lymph Node and Para-Aortic Lymph Node Metastases That Responded to Combined Modality Therapy and Underwent Conversion Surgery].

A 41-year-old woman with type 3 advanced gastric cancer and Virchow lymph node, para-aortic lymph node, and multiple bone metastases was diagnosed with U-less cType 3 cT4aN3M1, cStage IV. We administered docetaxel, cisplatin, and S-1 (DCS)therapy for unresectable gastric cancer. After 11 courses of DCS, we confirmed that the distant lymph node metasta- ses were significantly reduced. We performed radiotherapy(30 Gy/10 Fr)on the thoracic lumber vertebrae. Because the patient was successfully downstaged, we performed total gastrectomy with Roux-en-Y reconstruction. The histopathological diagnosis was ypT3N2M0, ypStage III A. In this case, DCS therapy successfully treated gastric cancer with distant metastases, including multiple bone metastases.

[A Case of Locally Advanced Breast Cancer Successfully Treated with Local Control That Achieved a Pathological Complete Response after Bevacizumab and Paclitaxel Combination Chemotherapy].

A 68-year-old woman with a 5-year history of an untreated left breast tumor presented to our hospital. She was admitted for untreated diabetes and severe anemia. The cause of the anemia was bleeding from the tumor, and she was referred to our department. She was diagnosed with T4bN0M0, stage IIIb breast cancer. First, we initiated hormonal therapy. However, the tumor did not decrease in size. We then administered chemotherapy. The tumor markedly decreased in size, and mastectomy and axillary lymph node dissection were performed. The response was a pathological complete response. She is currently undergoing hormonal therapy at the time of this writing.

Buried bumper syndrome in percutaneous endoscopic gastrostomy with a jejunal extension tube in patients undergoing levodopa-carbidopa intestinal gel treatment.

BACKGROUND: Levodopa-carbidopa intestinal gel (LCIG) treatment is an effective Parkinson's disease (PD) treatment that requires percutaneous endoscopic gastrostomy with a jejunal extension tube (PEG-J). Buried bumper syndrome (BBS) is an uncommon but significant complication of PEG-J for LCIG. Case presentation A 71-year-old man had been undergoing LCIG therapy for PD since a PEG-J was implemented at our department two years previously. He presented with appetite loss. Computed tomography showed that the gastrostomy bumper was buried in the gastric wall. The patient was surgically treated with the simultaneous removal and replacement of PEG-J. Postoperative gastrocutaneous fistula occurred, which was conservatively treated. CONCLUSIONS: Notably, patients and medical staff should be aware that patients with PD on LCIG treatment have a high risk of BBS in PEG-J and that there might be some patients with latent BBS. When simultaneous removal and replacement surgery is performed, establishing a new route at the stomach and abdominal wall is recommended.

Segmental cervical esophagectomy with free jejunal flap reconstruction for cervical esophageal cancer in patients with previous history of gastric surgery: a report of two cases.

Although free-flap jejunal reconstruction is frequently performed after cervical esophagectomy for cervical esophageal cancer, the procedure after gastric surgery has not been reported. We encountered two patients with esophageal cancer and previous gastric surgeries who eventually underwent segmental esophagectomy with free-flap jejunal reconstruction. Case one involved a 75-year-old man who underwent abdominal abscess and duodenal ulcer perforation surgeries (abdominal drainage and subsequent gastrojejunal bypass). A type 0-IIa tumor was located posterior to the cervical esophagus's right wall, 21 cm from the incisor, without lymph node swelling or distant metastasis. The left lobe of the thyroid gland was mobilized to ensure an oral resection margin. Severe abdominal adhesions required careful adhesiolysis to harvest the jejunum (20 cm long) 40 cm from the jejunojejunostomy. An end-to-side and side-to-end esophagojejunostomy were performed for the proximal and distal ends, respectively. Case two involved a 75-year-old male with a history of distal gastrectomy with Billroth I reconstruction for early gastric cancer. A submucosal tumor-like lesion was located on the cervical esophageal wall on the left side, 21 cm from the incisor. The distal esophagus required additional segmental resection because the anal resection line was close to the tumor. Jejunum (10 cm long) 30 cm from Ligament of Treitz was harvested. An end-to-side and end-to-end esophagojejunostomy for the proximal and distal ends, respectively, was performed. This surgery requires a thorough preoperative examination to ensure an adequate surgical margin and a careful free-flap harvest based on post-gastric surgery anatomy.

Therapeutic strategy aiming at R0 resection for borderline-resectable esophageal squamous cell carcinoma using induction chemotherapy with docetaxel, cisplatin, and 5-fluorouracil.

OBJECTIVE: Treatment for borderline resectable (cT3br) esophageal squamous cell carcinoma (SCC) is currently undefined. This study aimed to analyze the outcome of treatment strategies including induction chemotherapy with docetaxel, cisplatin, and 5-fluorouracil (DCF) against T3br esophageal SCC. METHODS: A total of 32 patients with cT3br esophageal SCC enrolled in this study were treated with two cycles of DCF induction therapy. RESULTS: The overall response rate to DCF induction therapy was 62.5%, while the disease control rate was 93.8% (complete response (CR), three; partial response (PR), 17; stable disease (SD), 10; progressive disease (PD), 2). After DCF induction chemotherapy, 27 patients underwent conversion surgery (CS) and five patients underwent definitive chemoradiotherapy (CRT). Out of 27 patients who underwent CS, 17 underwent transthoracic esophagectomy and 10 underwent thoracoscopic esophagectomy. Anastomotic leakage occurred in five patients (18.5%) and pneumonia in four (14.8%). Recurrent laryngeal nerve paralysis and arrhythmia were observed in two patients (7.4%). The R0 resection rate was 81.5%. Among the five patients who underwent definitive CRT, only one patient (20.0%) achieved CR. Two patients (40.0%) had PR and two (40.0%) had PD. Salvage esophagectomy was performed in one patient after definitive CRT. The 1-, 3-, and 5-year overall survival rates were 75.0, 50.6, and 46.4%, respectively, whereas the 1-, 3-, and 5-year disease-free survival rates were 54.9, 38.8, and 38.8%, respectively. CONCLUSION: DCF induction therapy and subsequent CS or definitive CRT are promising treatment strategies for cT3br esophageal SCC.

Successful combined laparoscopic and thoracoscopic surgery for esophago-mediastinal fistulae.

Minimally invasive surgeries have been developed, not only for gastrointestinal cancer, but also for benign or emergency cases. We report the case of a 62-year-old male who underwent laparoscopic and thoracoscopic combined surgery for an esophago-mediastinal fistula caused by a press-through package. In the initial laparoscopic phase, transhiatal dissection of the lower thoracic esophagus and harvesting of the greater omentum were performed. In the thoracoscopic phase, resection of the fistula and esophageal wall closure were performed. Thereafter, the greater omentum was lifted via the esophageal hiatus and wrapped around the repaired part of the esophagus for reinforcement. The total operative time was 371 min, with 163 and 208 min for the laparoscopic and thoracoscopic phases, respectively. In total, 20 ml of blood was lost. No perioperative complications or recurrences were observed. Laparoscopic and thoracoscopic combined omentoplasty was effective for refractory esophago-mediastinal fistula.

Strategy Treatment of cT4b Esophageal Squamous Cell Carcinoma Using Docetaxel, Cisplatin, and 5-Fluorouracil.

BACKGROUND/AIM: This study analyzed the outcomes of docetaxel, cisplatin, and 5-fluorouracil (DCF) therapy and DCF plus concurrent radiotherapy (DCF-RT), both followed by conversion surgery, if possible, in patients with cT4b esophageal cancer. PATIENTS AND METHODS: Forty-six patients with cT4b esophageal cancer, including borderline cT4b lesions, were eligible. Borderline cT4b lesions were treated with induction DCF therapy. For definitive cT4b lesions, definitive DCF-RT was administered. Patients unsuitable for induction DCF therapy or DCF-RT were treated with other therapies. After treatment, conversion surgery (CS) was performed for the residual tumor in resectable cases. RESULTS: Induction DCF therapy was administered to 12 patients (group A), and DCF-RT was provided to 18 patients (group B). Meanwhile, other therapies were provided to 16 patients (group C). The 1-, 3-, and 5-year overall survival (OS) rates were 66.7, 30.0, and 15.0%, respectively, in group A; 66.7, 37.5, and 37.5%, respectively, in group B; and 62.5, 0, and 0%, respectively, in group C. DCF-RT tended to prolong survival, albeit without significance (p=0.1040). The group A + B had significantly better overall survival than group C (p=0.0437). Fourteen patients underwent CS (30.4%), and patients who underwent CS had significantly better overall survival than those who did not undergo surgery (p=0.0291). CONCLUSION: Induction DCF or DCF-RT is promising for the treatment of cT4b esophageal cancer. Effective CS including combined resection of the invaded organ can contribute to improved therapeutic outcomes.

Clinical Effectiveness of Intermittent Infusion Hemodiafiltration Using Backfiltration of Ultrapure Dialysis Fluid Compared with Predilution On-Line Hemodiafiltration.

BACKGROUND: In conventional hemodialysis (HD) treatment, excessive water removal sometimes induces a rapid drop in blood pressure. Intermittent infusion hemodiafiltration (I-HDF) has been developed to improve patients' peripheral circulation by repeated intermittent infusion during HD treatment. SUMMARY: A prospective, multicenter, parallel group comparative trial examined the clinical effectiveness of I-HDF compared with predilution on-line HDF (pre-HDF), the most popular on-line HDF therapy in Japan. Patients were allocated to 2 groups after matching for age (± 5 years), dry weight (± 5 kg), and presence/absence of diabetes. After informed consent was obtained, 36 patients (18 pairs) participated in the trial. The results showed no difference in clinical condition or quality of life (QOL) scores between the 2 therapy groups. The rate of reduction in systolic blood pressure initially showed no difference between the groups, but decreased slightly as the trial proceeded after changing from HD therapy. There was also no difference in the incidence rate of treatments initially, although this significantly decreased in both groups as the trial proceeded. Rates of ß2-microglobulin removal were significantly higher in the pre-HDF group than in the I-HDF group. At the same time, the amount of albumin leakage during treatment was significantly greater in the pre-HDF group. Key Messages: The clinical condition and QOL of patients receiving I-HDF was not inferior to those receiving pre-HDF. Pre-HDF demonstrated a significantly higher removal rate of middle- and larger-molecular-weight solutes and higher albumin leakage compared with I-HDF.

Validity of neoadjuvant chemotherapy with docetaxel, cisplatin, and S-1 for resectable locally advanced gastric cancer.

Gastrectomy with D2 lymphadenectomy plus postoperative chemotherapy is the standard treatment for resectable locally advanced gastric cancer in Japan. However, the prognosis of patients with serosa-positive tumors remains unsatisfactory because of peritoneal recurrence. This study aimed to investigate the validity of neoadjuvant therapy with docetaxel, cisplatin, and S-1 (DCS) in patients with locally advanced gastric cancer. Thirty patients with locally advanced gastric cancer underwent neoadjuvant DCS therapy at Dokkyo Medical University Hospital between June 2013 and October 2015. Gastrectomy and D2 lymphadenectomy were performed after two cycles of preoperative DCS therapy. The clinical responses of the primary gastric tumors based on endoscopic findings were partial response in 17 patients (57%) and stable disease in 13 patients (43%). Analysis of pathological response in the primary gastric lesions showed grade 1a in five patients (17%), grade 1b in nine patients (30%), grade 2 in 11 patients (37%), and grade 3 in five patients (17%). Twenty-four patients (80%) remained alive after a median follow-up period of 31 months. The 2- and 3-year overall survival rates in all patients were 89 and 70%, respectively. The 2-year overall survival rate in pathological responders (grade 1b-3) was 96%, compared with 50% in pathological non-responders (grade 1a) (P = 0.00187). Pathological responders had a significantly higher survival rate than non-responders. These results indicate that neoadjuvant DCS therapy may improve the prognosis in patients with serosa-positive locally advanced gastric cancer.

Hypopharyngeal perforation caused by intraoperative transesophageal echocardiography.

Intraoperative transesophageal echocardiography (TEE) is an invaluable tool for cardiac surgical decision-making. TEE is considered reasonably noninvasive and safe, but insertion and manipulation of the TEE probe can lead to complications. Here, we report a patient with aortic stenosis who experienced TEE-associated hypopharyngeal perforation at the pyriform sinus complicated by esophageal trauma, pneumomediastinum and pneumoretroperitoneum. Based on this case, we suggest that rare complications be kept in mind when using TEE intraoperatively.

Phase I Dose-Escalation Study of Docetaxel, Cisplatin, and 5-Fluorouracil Combination Chemotherapy in Patients With Advanced Esophageal Carcinoma.

A dose-escalation study of docetaxel (DOC), cisplatin (CDDP), and 5-fluorouracil (5-FU; DCF combination regimen) was performed to determine the maximum-tolerated dose (MTD), recommended dose (RD) and dose-limiting toxicities (DLT) in advanced esophageal carcinoma. Eighteen patients with esophageal carcinoma were enrolled and received DCF combination therapy at different dose levels. DLTs included febrile neutropenia and oral mucositis. DLT occurred in 2 out of 6 patients at level 2 and 3. The study proceeded to level 4, according to the protocol. The level 4 dose was defined as the MTD and the level 3 dose was defined as the RD. The RD for DCF combination chemotherapy for advanced esophageal carcinoma in the present study was 70 mg/m(2) DOC plus 70 mg/m(2) CDDP on day 1 plus 700 mg/m(2) 5-FU on days 1-5 at 4-week intervals. This regimen was tolerable and highly active. A phase II study has been started.
