RESUMO

BACKGROUND/AIM: The chemokine receptors C-X-C chemokine receptor type 4 (CXCR4) and C-C chemokine receptor type 7 (CCR7) play an important role in the invasion and metastasis of cancer. This study investigated the relationship between relative expression of CXCR4 and CCR7 mRNA, clinicopathological factors, and outcomes in patients with colorectal cancer (CRC). PATIENTS AND METHODS: We studied 202 patients who underwent surgery for CRC. The expression levels of CXCR4 and CCR7 mRNA in cancerous tissue were measured using quantitative real-time reverse-transcriptase polymerase chain reaction. RESULTS: High CCR7 mRNA expression levels in CRC tissues were positively associated with tumour size and were more frequently associated with cancer of the rectum than of the colon. Moreover, outcomes were significantly poorer in patients with high CCR7 mRNA expression than in those with low expression. On multivariate Cox regression analysis, a higher CCR7 mRNA expression level was a significant independent predictor of poorer overall survival in patients with CRC. CONCLUSION: Overexpression of CCR7 mRNA may be a useful independent prognostic factor in patients with CRC.

RESUMO

BACKGROUND: Post-operative pneumonia is a major complication after general elective surgery in elderly patients and is often caused by aspiration associated with oesophageal reflux. The aim of this study was to identify the risk factors of post-operative pneumonia after gastrectomy in elderly patients with gastric cancer with two potential risk factors of ageing and oesophageal reflux. METHODS: We retrospectively examined the data of 251 patients ≥75 years old who underwent gastrectomy between January 2014 and December 2018 in our institution. The reconstruction methods were Billroth-I or Roux-Y after distal gastrectomy, jejunal interposition or double tract after proximal gastrectomy and Roux-Y after total gastrectomy. The severity of pneumonia was evaluated by the Clavien-Dindo classification. RESULTS: Post-operative pneumonia was identified in 15 patients (5.9%) and was significantly associated with an age ≥80 years old, poor performance status, history of smoking and cardia-non-preserving gastrectomy (total gastrectomy and proximal gastrectomy) in univariate analyses. Multivariate analyses showed that a poor performance status and cardia-non-preserving gastrectomy were independent risk factors for post-operative pneumonia. The patients who suffered post-operative pneumonia required a longer hospital stay than those without post-operative pneumonia (P = 0.002). CONCLUSION: We identified a poor performance status and cardia-non-preserving gastrectomy, which are likely to lead to oesophageal reflux, as risk factors for post-operative pneumonia in elderly patients with gastric cancer. These results warrant further prospective studies to evaluate their utility for reducing the rate of post-operative pneumonia in elderly patients through cardia-preserving gastrectomy or anti-reflux reconstruction.

RESUMO

BACKGROUND: Renal cell carcinoma (RCC) is a primary tumor with the highest frequency of pancreatic metastasis. Although surgical resection can improve the prognosis of some patients with pancreatic metastasis of RCC (PM-RCC), the role of palliative surgery remains unclear. Herein, we described a case of jejunal limb occlusion caused by a tumor thrombus arising from a PM-RCC which was treated by surgical resection. CASE PRESENTATION: A 75-year-old, male patient with metastatic RCC was admitted to our hospital with new-onset dysphagia and weight loss. Twenty years earlier he underwent a right nephrectomy with an adrenalectomy for the first surgical resection of RCC, and 12 years ago he underwent a left partial nephrectomy for metachronous primary RCC. Nine years later, multiple pancreatic metastases were detected. After discontinuing interferon therapy, he was followed up at his request without anticancer treatment. Multiple, pulmonary metastases developed 3 years ago, and resection of a brain metastasis was performed 6 months ago. He had also undergone a total gastrectomy with Roux-en Y reconstruction and splenectomy for gastric cancer 23 years ago. Computed tomography revealed a metastatic lesion in the pancreatic tail extending into the jejunal limb, which was obstructed by a tumor thrombus. Jejunal limb resection was performed concomitantly with a distal pancreatectomy as palliative surgery. The jejunal limb remnant was approximately 30 cm long and was re-anastomosed to the esophagus using a circular stapler. Blood perfusion at the anastomotic site was confirmed by indocyanine green fluorescence imaging. He was discharged on postoperative day 24 and was followed in the outpatient clinic. He achieved sufficient oral intake at 8 months postoperatively. CONCLUSIONS: PM-RCC can invade the gastrointestinal tract and cause tumor thrombus formation resulting in bowel occlusion requiring surgical intervention.

RESUMO

BACKGROUND: A multi-institutional phase II study was conducted to evaluate the efficacy and safety of preoperative docetaxel, cisplatin and S-1 therapy in marginally resectable advanced gastric cancer. METHODS: Patients with macroscopic type 4, large macroscopic type 3 and bulky lymph node metastasis received two cycles of preoperative docetaxel, cisplatin and S-1 therapy (docetaxel 40 mg/m2 and cisplatin 60 mg/m2 on day 1, and S-1 80 mg/m2 for 14 days, every 4 weeks). The primary endpoint was the pathological response rate, with an expected value of 65%. RESULTS: Thirty-one patients were enrolled in this study. The pathological response rate was 54.8%, and it was higher than the threshold value but lower than the expected rate. The R0 resection rate was 93.5%. The frequencies of grade 3-4 toxicities during docetaxel, cisplatin and S-1 therapy were 41.9% for neutropenia, 6.5% for febrile neutropenia and 32.3% for nausea/vomiting. Grade 2 and 3 surgical morbidities occurred in 23.3 and 6.7% of the patients, respectively. CONCLUSIONS: Preoperative docetaxel, cisplatin and S-1 therapy was feasible in terms of chemotherapy-related toxicities and surgical morbidity, but the effect did not achieve the expected value. The association between the pathological response rate and survival will be evaluated in the final analysis of this clinical trial.

RESUMO

OBJECTIVE: To investigate the prognostic values of the preoperative modified Glasgow Prognostic Score (mGPS) and carcinoembryonic antigen (CEA) alone and combined in elderly patients with colorectal cancer (CRC) planning to receive curative surgery. METHODS: We retrospectively analyzed 130 elderly patients (aged ≥80 years) with CRC who received curative surgery between 2008 and 2016. The preoperative mGPS and CEA levels were calculated. RESULTS: Elevated preoperative mGPS or CEA level was significantly associated with shorter relapse-free survival (p = 0.005, both) and cancer-specific survival (p = 0.011 and p < 0.001, respectively). Combined use of these two factors improved the predictive accuracy for tumor recurrence relative to that of either factor. CONCLUSION: Both mGPS and CEA were independent prognostic factors of CRC in elderly patients receiving curative surgery, but their combination was more accurate.

RESUMO

Gastrojejunostomy has been performed as a palliative treatment for unresectable, advanced gastric cancer patients with gastric outlet obstruction (GOO). However, its role before neoadjuvant chemotherapy (NAC) has not been established. We present the case of a 72-year-old man with distal advanced gastric cancer with GOO. Computed tomography showed para-aortic lymph node (PAN) metastasis without other distal metastasis. We performed laparoscopic stomach-partitioning gastrojejunostomy (LSPGJ), which avoided new gastrojejunostomy reconstruction when performing distal gastrectomy after NAC. His oral intake improved after surgery and NAC was successfully administered on postoperative day 14, without surgical complications. After completion of NAC, the patient underwent radical distal gastrectomy with gastrojejunostomy reused as Billroth-II reconstruction. A histological examination revealed no residual cancer cells. LSPGJ, with partitioning on the expected resection line in distal gastrectomy after NAC, can be useful for treating advanced gastric cancer with GOO when NAC followed by curative gastrectomy is planned.

RESUMO

Here, we report a case of successful surgical resection of expansive-growth acinar cell carcinoma. A 59-year-old man was referred to a local hospital with abdominal distention. CT revealed a large abdominal tumor. Subsequently, he was referred to our hospital. Physical examination showed a large tumor on his left upper abdomen without tenderness. CT revealed an enhanced 18 cm-sized expansive-growth tumor on the left flank, suggesting a primary pancreatic tumor. EUS-FNA yielded a diagnosis of adenocarcinoma. Imaging findings were not typical for pancreatic ductal carcinoma. We performed distal pancreatectomy with splenectomy, transverse colon resection, and proximal gastrectomy. Pathological findings revealed a tumor, measuring 19.5×16.5×15.5 cm, originating from the pancreatic body, positive for trypsin, chymotrypsin, and elastase, consistent with a diagnosis of acinar cell carcinoma, pT3, N0, M0. Four courses of adjuvant chemotherapy with S-1 were provided, and the patient is currently alive without recurrence for 10 months.

RESUMO

Perforated gastric cancer reported to be relatively rare and to have a poor prognosis. This study examined 9 patients with perforated gastric cancer. Two-thirds of the patients were male and the median age was 69 years. The timing of the diagnosis of gastric cancer was preoperative clinical findings in 4 cases, intraoperative surgical findings in 3 cases, and postoperative examination in 2 cases. The depths of tumor invasion were T3 in 3 cases, T4a in 4 cases, and T4b in 2 cases and 5 patients were Stage Ⅳ. Four patients underwent palliative gastrectomy and only 1 patient underwent curative(R0)gastrectomy. Four patients underwent repair surgery, 2 of which underwent omental patch repair during the initial surgery. One of patients with omental patch repair received 2-stage curative gastrectomy; the other patient received chemotherapy after recovering from acute peritonitis. The median overall survival was 17.9 months and the prognosis was favorable in cases with curative resection or chemotherapy. For patients with perforated gastric cancer, if curative resection cannot be expected, the initial surgery should be directed toward the treatment of peritonitis and radical oncological surgery or systemic chemotherapy should be planned following patient recovery.

RESUMO

Only a few studies have been conducted regarding the palliative radiation therapy(RT)for gastric cancer(GC)bleeding. Data of 9 patients with gastric cancer requiring blood transfusions due to gastric bleeding who were treated with RT were reviewed. All patients were men with a median age of 83(range, 70-91)years. The clinical stage was ⅡB in 2 patients, Ⅲin 1, ⅣA in 1, and ⅣB in 5. Performing gastrectomy was difficult in 4 patients with distant metastasis or tumor invasion to adjacent organ, 3 with poor performance status, and 2 with advanced age. The median hemoglobin levels before RT was 6.0 (range, 3.3-7.7)g/dL, and all patients received blood transfusions before RT. Seven patients received 30 Gy RT and 2 patients received 50 Gy. Two patients received concurrent chemotherapy. A total of 2 hematological and 4 non-hematological treatment-related adverse events occurred. All patients improved conservatively. Hemorrhage occurred in 8 patients, except for 1. Of the 8 patients who responded to RT, 1 had rebleeding on day 81. The median rebleeding-free survival time from the beginning of RT was 125(range, 21-421)days. Palliative radiation therapy was useful for bleeding control in nonresectable gastric cancer.

RESUMO

Laparoscopic-assisted total gastrectomy(LATG)has several complications early during the introduction of the procedure, so a careful approach is necessary. In this study, we evaluated short-term outcomes after LATG at our hospital. From 2014 to 2017, 21 patients underwent LATG using ENDO-PSI. A 6-cm midline incision was made at the epigastrium, and the abdominal esophagus was transected using ENDO-PSI. The anvil head was fixed with extracorporeal ligation, and an end loop was added to the proximal side of the first suture. Reconstruction was performed with the Roux-en-Y method. The jejunojejunal anastomosis was performed extracorporeally, and esophagojejunostomy was performed using a circular stapler through the small incision. There were 15 men and 6 women, with a mean age of 74 years. The mean operation time was 296 min, and volume of blood loss was 75 mL. The median fasting period was 3(3-10)days, and the postoperative hospitalization period was 12(8-28)days. The postoperative complications were Grade Ⅱ in 4 patients and Grade Ⅲ in 1 patient. The complication due to esophagojejunostomy was anastomotic leakage in 1 patient, while no anastomotic stenosis was found. LATG using ENDO-PSI can be safely performed.

RESUMO

The aim of this study was to compare the outcome of using trans-anal ileus tube and self-expandable metallic stent(SEMS) for obstructive colorectal cancer. METHODS: Between 2014 and 2018, 14 patients received trans-anal ileus tube placement (group I)and 34 received SEMS insertion as bridge to surgery(BTS)and underwent primary resection. RESULTS: The technical success rate was 100%in both groups, and the clinical success rate was 85.7%(12/14 cases)in group I and 91.2%(31/34 cases)in group S. In group S, the CROSS score significantly improved, the rates of stoma construction and postoperative complications were significantly lower, and the period until oral intake and hospital discharge was significantly short. CONCLUSION: SEMS insertion is more effective than trans-anal ileus tube placement in terms of short-term outcome.

RESUMO

The aim of this study was to clarify the risk factors of severe postoperative complications and prognostic factors in patients who underwent emergent surgery for colorectal cancer perforation. ASA-PSB3 and Mannheim Prognostic Index(MPI)B27 were selected as the independent risk factors for postoperative severe complications on multivariate analysis. Moreover, severe postoperative complications and non-curative surgery were selected as the independent factors of poor prognosis.

RESUMO

In elderly patients, surgical procesure is decided considering the general condition and surgical invasion. The aim of this study was to clarify the appropriate rage of lymph node dissection for elderly colorectal cancer patients. One hundred forty one colorectal cancer patients aged 75 years or more, who underwent R0 colorectal resection with D2 or D3 lymph node dissection in clinical T3/T4 or clinical N+, were enrolled in this study. The patients whose tumor located in the rectum below the peritoneal reflection(Rb)were excluded. Five-year overall survival(OS)rate and disease specific survival(DSS)rate were 79.1% and 89.4%, respectively. More than 2 preoperative co-morbidities and macroscopic type 3-5 were independent prognostic factors in OS, whereas the rage of lymph node dissection was not risk factor. When comparing the outcomes of D2 and D3 dissections by age, D3 dissection was better tendency in DSS in patients aged under 80, however, D2 dissection was better tendency in patients aged 80 or more. In elderly colorectal cancer patients, there was no difference in prognosis between D2 and D3 dissection, and especially in patients aged 80 years or more, D2 might be sufficient if R0 resection was possible.

RESUMO

BACKGROUND: Lean body mass loss after surgery, which decreases the compliance of adjuvant chemotherapy, is frequently observed in gastric cancer patients who undergo gastrectomy for gastric cancer. However, the risk factors for loss of lean body mass remain unclear. METHODS: The current study retrospectively examined the patients who underwent curative gastrectomy for gastric cancer between June 2010 and March 2014 at Kanagawa Cancer Center. All the patients received perioperative care for enhanced recovery after surgery. The percentage of lean body mass loss was calculated by the percentile of lean body mass 1 month after surgery to preoperative lean body mass. Severe lean body mass loss was defined as a lean body mass loss greater than 5 %. Risk factors for severe lean body mass loss were determined by both uni- and multivariate logistic regression analyses. RESULTS: This study examined 485 patients. The median loss of lean body mass was 4.7 %. A lean body mass loss of 5 % or more occurred for 225 patients (46.4 %). Both uni- and multivariate logistic analyses demonstrated that the significant independent risk factors for severe lean body mass loss were surgical complications with infection or fasting (odds ratio [OR] 3.576; p = 0.001), total gastrectomy (OR 2.522; p = 0.0001), and gender (OR 1.928; p = 0.001). CONCLUSIONS: Nutritional intervention or control of surgical invasion should be tested in future clinical trials for gastric cancer patients with these risk factors to maintain lean body mass after gastrectomy.

RESUMO

Adrenal metastasis from colorectal cancer occurs in the presence of multiple synchronous metastases at other sites. We report a case of heterochronous solitary adrenal metastasis from rectal cancer. A 55-year-old man underwent anterior resection with D3 lymph node dissection for rectal cancer. The pathological stage of the tumor was III b, and adjuvant chemotherapy with mFOLFOX6 was administered for 6 months. Eighteen months after surgery, abdominal computed tomography(CT) revealed right solitary adrenal metastasis. His tumor marker levels were considerably elevated; therefore, he received preoperative chemotherapy with FOLFIRI plus bevacizumab(BV). After preoperative chemotherapy, his tumor marker levels decreased, and CT and FDG-PET/CT did not uncover any other metastatic lesions. The patient was diagnosed with solitary adrenal metastasis, and right adrenalectomy was performed. Histological examination confirmed the tumor to be adrenal metastasis from rectal cancer, and the histopathological Grade was 2. The patient received adjuvant chemotherapy with mFOLFOX6, and he is alive 7 months after adrenalectomy without evidence of recurrence. Adrenalectomy is recommended for solitary adrenal metastasis from colorectal cancer. Additionally, adrenalectomy after preoperative chemotherapy is an effective strategy for patients with solitary adrenal metastasis and high tumor marker levels.

RESUMO

BACKGROUND: A significant body weight loss (BWL) is observed during 1 month after gastrectomy for gastric cancer. However, it remains unclear which body component mainly accounts for the weight loss. METHODS: Two-hundred forty-four patients who underwent gastrectomy for gastric cancer between May 2010 and October 2013 were examined. Body weight and composition were evaluated by a bioelectrical impedance analyzer within 1 week before surgery (first measurement), at 1 week after surgery (second measurement), and at 1 month after surgery (third measurement). The changes in the early period were defined as the differences until the second measurement, and those in the late period were defined as the differences from the second to the third measurement. RESULTS: Total BWL within 1 month was -3.4 kg, and the rate of body weight at 1 month to the preoperative body weight was 94.1 %. BWL was significantly greater in the early period than in the late period (-2.1 kg vs -1.2 kg, p < 0.001). In the early period, loss of lean body mass was significantly greater than loss of fat mass (-1.5 kg vs -0.6 kg, p < 0.001). The same trend was observed when the subset of patients who had surgical morbidities was excluded. CONCLUSION: BWL during the first week after surgery was significantly greater than that during the subsequent 3 weeks. Furthermore, loss of lean body mass accounted for a significant part of the BWL during the first week.

RESUMO

We report 2 cases of signet ring cell carcinoma of the appendix and colon. Case 1: A 61-year-old man was admitted for lower abdominal pain. Colonoscopy revealed an elevated lesion in the orifice of the appendix. Signet ring cell carcinoma was diagnosed on biopsy. The surgical findings showed multiple peritoneal dissemination nodules, while the primary tumor was unresectable owing to extensive invasion into the retroperitoneum. The histopathological findings were signet ring cell carcinoma, T4b (retroperitoneum), NX, P3, Stage Ⅳ. Although the patient received 14 courses of treatment with S-1 as postoperative chemotherapy, he died of his illness at 32 postoperative months. Case 2: A 76-year-old man was admitted for abdominal pain. Perforation of the lower gastrointestinal tract was diagnosed on abdominal CT, and an emergency operation was performed. The surgical findings demonstrated a large number of peritoneal dissemination nodules, cecal invasion of a sigmoid tumor, and perforation of the ascending colon. The primary tumor was thought to be unresectable, and the perforated segment was resected. The histopathological findings were signet ring cell carcinoma, T4b (cecum), NX, P3, Stage Ⅳ. Although 11 courses of treatment using FOLFIRI+Bev were administered as postoperative chemotherapy, the patient died of his illness at 26 postoperative months.

RESUMO

In March 2011, trastuzumab was approved for treating human epidermal growth factor receptor 2 (HER2) positive advanced gastric cancer (AGC) in Japan. Therefore, all patients with AGC should be evaluated for HER2 status. In this study, we analyzed the clinicopathological features and current status of treatment in HER2 positive gastric cancer. One hundred 6 gastric cancer patients were examined for HER2 expression in our hospital between March 2011 and August 2014. Sixteen patients (15.1%) were HER2 positive. There was no correlation between HER2 status and age, sex, and location of tumor; however, HER2 positivity was significantly more frequent in patients with intestinal type tumors and had a tendency towards being more frequent in patients with macroscopic types 0, 1 or 2. Trastuzumab was administered to 10 patients with HER2 positive AGC. The total number of doses of trastuzumab was 1 to 44 (median 7.5), and the therapeutic effect of trastuzumab combination chemotherapy was 1 patient with a complete response and 4 with a partial response. Adverse events due to trastuzumab were not observed. The incidence of HER2 over-expression was 15.1%, and trastuzumab combination chemotherapy was relatively safe and effective.

RESUMO

A 64-year-old woman was diagnosed with Stage IV gastric cancer with lymph node and multiple liver metastases. She was treated with 6 courses of chemotherapy, in 3-week courses, with capecitabine (1,000 mg/m/(2)) plus cisplatin(80 mg/m(2)) administered for 2 weeks, followed by a drug-free week. She underwent curative total gastrectomy with D2 lymph node dissection and reconstruction by using the Roux-en-Y method. The postoperative pathological findings revealed a T3 (SE), N1M1, Stage II B tumor; the tumor was determined to be Grade 1b owing to the chemotherapeutic effect. Postoperatively, only S-1 therapy was administered, because of the development of Grade 3 hand-foot syndrome. The patient is alive 1 year and 8 months after the initial gastrectomy.
