RESUMO

BACKGROUND: This study evaluated the perioperative outcomes for patients who had locally advanced esophageal adenocarcinoma (EAC) treated with neoadjuvant immunotherapy (IO) and chemotherapy versus a matched cohort of patients who received neoadjuvant chemotherapy (NAC) alone. METHODS: A single-center non-randomized phase 2 trial was undertaken with locally advanced (cT3-4 and/or N+) EAC, and 49 patients completed neoadjuvant avelumab + docetaxel, cisplatin, 5FU (DCF) and esophagectomy between February 2018 and February 2020. These patients were matched with contemporary patients (January 2018 to June 2020) who met the inclusion criteria but received neoadjuvant chemotherapy alone (NAC) with a comparable docetaxel-based therapy. The postoperative outcomes then were compared between the two groups. RESULTS: For this study, 99 patients with locally advanced EAC underwent esophagectomy and met the enrolment criteria. Of these patients, 50 received NAC alone and 49 received IO + NAC. Baseline characteristics such as age, gender, and clinical stage were comparable between the two groups. Operative approach and rate of minimally invasive esophagectomy (~ 60%) were similar in the two groups. For the NAC-alone and IO + NAC groups, the respective overall and major complication rates were similar between the two groups (50% vs. 51% [p = 0.91] and 20% vs. 26% [p = 0.44], respectively), with concordant rates for anastomotic leak (6 [12%] vs. 6 [12%]; p = 0.86) and respiratory complications (13 [26%] vs. 11 [22%]; p = 0.68). The two groups did not differ significantly in terms of hospital length of stay or 30- and 90-day mortality rates. CONCLUSION: The addition of immunotherapy to neoadjuvant chemotherapy for locally advanced esophageal adenocarcinoma does not appear to alter perioperative short-term outcomes significantly after esophagectomy.

RESUMO

Gastric adenocarcinoma is a leading cause of cancer death worldwide. The management of this aggressive malignancy largely depends on tumor characteristics especially stage. Superficial early-stage gastric cancer can be safely managed by endoscopic resection, though clear negative deep and lateral margins must be obtained. Optimal surgical resection is an essential part of the treatment for locally advanced gastric adenocarcinoma, with perioperative and adjuvant therapies having significant impact on long-term outcomes. Chemoradiation is reserved for patients with suboptimal surgical resection. Recent therapeutic advances have prolonged survival in patients with metastatic gastric adenocarcinoma, include checkpoint inhibitors and biomarker-directed therapy. Targeted therapies in gastric adenocarcinoma include monoclonal antibodies directed against vascular endothelial growth factor (VEGF), vascular endothelial growth factor receptor-2 (VEGFR-2), and human epidermal growth factor receptor 2 (HER2). While anti-VEGF therapies were not found beneficial in the perioperative setting, the effectiveness of HER2 targeted agents in resectable HER2-positive gastric adenocarcinoma is being studied. Microsatellite instability (MSI) varies greatly in patients with gastric adenocarcinoma between 5-20% based on ethnic origin, tumour heterogeneity and staging. The role chemotherapy in the perioperative setting for patients with MSI-high tumors remains controversial while immunotherapy demonstrates promising results in preliminary studies. Immune checkpoint inhibitors in combination with chemotherapy has been shown to improve outcomes in patients with metastatic gastric adenocarcinoma who express programmed cell death 1 ligand 1 (PD-L1) and is now being investigated in the perioperative setting.

RESUMO

BACKGROUND: The neutrophil to lymphocyte ratio (NLR) has demonstrated prognostic value in various malignant conditions, including gastric adenocarcinoma. However, chemotherapy may affect NLR. OBJECTIVES: To evaluate the prognostic value of NLR as an accessory decision-making tool in terms of operating patients after neoadjuvant chemotherapy in patients with resectable gastric cancer. METHODS: We collected oncologic, perioperative, and survival data of patients with gastric adenocarcinoma who underwent curative intent gastrectomy and D2 lymphadenectomy between 2009 and 2016. The NLR was calculated from preoperative laboratory tests and classified as high (> 4) and low (≤ 4). The t-test, chi-square, Kaplan-Meier analysis, and Cox multivariate regression models were used to assess associations of clinical, histologic, and hematological variables with survival. RESULTS: For 124 patients the median follow-up was 23 months (range 1-88). High NLR was associated with greater rate of local complication (r=0.268, P < 0.01). The rate of major complications (Clavien-Dindo ≥ 3) was higher in the high NLR group (28% vs. 9%, P = 0.022). Among the 53 patients who received neoadjuvant chemotherapy, those with low NLR had significantly improved disease-free survival (DFS) (49.7 vs. 27.7 months, P = 0.025). Low NLR was not significantly associated with overall survival (mean survival, 51.2 vs. 42.3 months, P = 0.19). Multivariate regression identified NLR group (P = 0.013), male gender (P = 0.04), and body mass index (P = 0.026) as independently associated with DFS. CONCLUSIONS: Among gastric cancer patients planned for curative intent surgery who underwent neoadjuvant chemotherapy, NLR may have prognostic value, particularly regarding DFS and postoperative complications.

RESUMO

PURPOSE: Locoregional recurrence of esophageal carcinoma after neoadjuvant therapy and en bloc esophagectomy, although uncommon, is challenging to manage. Currently, there are no standard treatment approaches prompting many health care providers to adopt a palliative approach. We describe our experience and outcomes of treating this specific group of patients with a focus on salvage curative intent local therapy. METHODS: All patients undergoing en bloc esophagectomy following neoadjuvant therapy between 2007 and 2017 at the McGill University Health Centre, a tertiary referral center for esophageal cancer, were identified. Patient follow-up included a structured surveillance protocol with serial endoscopic and cross-sectional imaging studies. Local recurrence was defined as histologically confirmed recurrences at the anastomosis. Regional recurrence was defined as radiological evidence of celiac, mediastinal, or para-esophageal/conduit lymphadenopathy. Demographic, pathologic, therapeutic variables were extracted as well as disease free and overall survival. RESULTS: Of 755 patients identified, locoregional recurrences occurred in 27 patients (3.6%) of whom 18 were included in the analysis. The median disease-free survival post index operation was 15 months (IQR 10-23). The sites of recurrence were local (6/18, 33.3%); regional (8/18, 44.4%); and locoregional (4, 22.2%). Chemoradiation was the most common modality used to treat recurrence (10/18, 55.6%) whilst 4 (22.2%) underwent surgery. Following treatment for locoregional recurrence, 1-year overall survival was 61.1% and at 5 years was 22.2%. CONCLUSION: Consolidative salvage local therapy for locoregional recurrence after en bloc esophagectomy is feasible and can entail prolonged survival in a subset of patients.

RESUMO

BACKGROUND: Surgery, as part of a multimodal approach, offers the greatest chance of cure for esophageal cancer. However, esophagectomy is often perceived as having a lasting impact on quality of life (QOL), biasing some physicians and patients toward nonoperative management. A comprehensive understanding of the dynamic changes in patient-centered outcomes is therefore important for decision making. Our objective was to determine the long-term QOL after esophagectomy. METHODS: Data were obtained from a prospectively collected (2006-2015) esophagectomy database at a high-volume center, and patients surviving 3 or more years were identified. Health-related QOL was evaluated using the Functional Assessment of Cancer Therapy-Esophageal Module (FACT-E) at diagnosis and every 3 to 6 months, and was stratified according to operative approach, stage, and complications. In addition, QOL scores were compared with normative population values. RESULTS: Of 480 patients, 47% (n = 226) survived 3 or more years and 70% (158 of 226) completed the health-related QOL assessments. Time of follow-up was 5.1 ± 2.8 years. After a reduction at 1 to 3 months, FACT-E increased from a baseline of 126 (95% CI, 121-131) to 133 (95% CI, 127-139) at 12 months, and to 147 (95% CI, 142-153) by 5 years. There was no difference in long-term FACT-E with respect to the surgical approach, clinical and pathologic stage, or postoperative complications. At long-term follow-up (more than 3 years), QOL did not differ significantly from the normative population reference values. CONCLUSIONS: The long-term QOL of esophagectomy patients surviving at least 3 years is improved when compared with the time of diagnosis and does not differ from the general population.

RESUMO

Background: Palliative chemotherapy is the mainstay of treatment for metastatic gastric adenocarcinoma but in some patients, surgically correctable factors such as obstruction lead to intolerance of further systemic treatment. The aim of this study was to evaluate the role of selective palliative surgery in incurable gastric cancer. Methods: All patients with stage IV and locally advanced unresectable gastric adenocarcinoma treated at a single centre from March 2006 to January 2019 were included. Data were retrieved from a prospectively maintained database. Patients were categorized into palliative surgery (PS) and no surgery (NS). Results: Of 666 patients with gastric cancer treated over the study period, 146 patients had stage IV gastric adenocarcinoma and 121 patients met inclusion criteria. Sites of metastases were peritoneum (55; 46%), non-regional lymph nodes (10; 8%), solid organ (17, 14%), adjacent organ invasion (4, 3.3%) and a combination of factors (32, 26%). Forty-six (38%) patients underwent palliative surgery which included anatomical gastrectomy (total, subtotal, distal or proximal, 78%) gastro-jejunal bypass and feeding jejunostomy (12%). Thirty-day post-operative complications occurred in 24 patients (52%) with one mortality (2.1%). Following surgery, 52% received systemic chemotherapy. For the PS and NS groups respectively, median overall survival was 9.1 versus 9.4 months (p = 0.6) and median progression-free survival was 7.1 versus 6.7 months (p = 0.2) after a follow up period of 7.3 (4.7-13.1) versus 7.8 (2.6-13.4) months (p = 0.46). Conclusion: Targeted surgical intervention for incurable gastric cancer can be used to palliate symptoms and facilitate continuation of systemic therapy with acceptable risks and post-operative outcomes.

RESUMO

BACKGROUND: Pilonidal sinus is a chronic, inflammatory condition. Controversy exists regarding the best surgical management for pilonidal sinus, including the extent of excision and type of closure of the surgical wound. OBJECTIVES: To assess the short- and long-term outcomes and success rate of the trephine procedure for the treatment of pilonidal sinus. METHODS: A retrospective observational cohort study was conducted at a single center. Patients who underwent trephine procedure between 2011 and 2015 were included. Data collection included medical records review and a telephone interview to establish long-term follow-up. RESULTS: A total of 169 patients underwent the trephine technique for the repair of pilonidal sinus. Follow-up included 113 patients, median age 20 years. Initial postoperative period, 35.6% recalled no pain and 58.6% reported a mild to moderate pain. Postoperative complications included local infection (7.5%) and mild bleeding (15.1%). On early postoperative follow-up, 47.1% recalled no impairment in quality of life, and 25%, 21.2 %, and 6.7% had mild, moderate and sever disturbance respectively. The median time to return to work or school was 10 days. At a median follow-up of 29 months (IQR 19-40), recurrence rate was 45.1% (51/113), and 38 (33.9%) of the patients underwent another surgical procedure Overweight, smoking, and family history were associated with higher recurrence rate. CONCLUSIONS: The trephines technique has a significant long-term recurrence rate. Short-term advantages include low morbidity, enhanced recovery, and minimal to mild postoperative impairment to quality of life. The trephine procedure may be justified as a first treatment of pilonidal disease.

RESUMO

Surgical resection, the cornerstone of curative intent treatment for gastric adenocarcinoma, is associated with a high rate of infection-related post-operative complications, leading to an increased incidence of metastasis to the peritoneum. However, the mechanisms underlying this process are poorly understood. Lipopolysaccharide (LPS), an antigen from Gram-negative bacteria, represents a potential mechanism via induction of local and systemic inflammation through activation of Toll-like receptor (TLR). Here, we use both a novel ex vivo model of peritoneal metastasis and in vivo animal models to assess gastric cancer cell adhesion to peritoneum both before and after inhibition of the TLR4 pathway. We demonstrate that activation of TLR4 by either LPS or Gram-negative bacteria (E. coli) significantly increases the adherence of gastric cancer cells to human peritoneal mesothelial cells, and that this increased adherence is abrogated by inhibition of the TLR4 signal cascade and downstream TAK1 and MEK1/2 pathways. We also demonstrate that the influence of LPS on adherence extends to peritoneal tissue and metastatic spread. Furthermore, we show that loss of TLR4 at the site of metastasis reduces tumor cell adhesion, implicating the TLR4 signaling cascade in potentiating metastatic adhesion and peritoneal spread. These results identify potential therapeutic targets for the clinical management of patients undergoing resection for gastric cancer.

RESUMO

BACKGROUND: Pyloric drainage procedures, namely pyloromyotomy or pyloroplasty, have long been considered an integral aspect of esophagectomy. However, the requirement of pyloric drainage in the era of minimally invasive esophagectomy (MIE) has been brought into question. This is in part because of the technical challenges of performing the pyloric drainage laparoscopically, leading many surgical teams to explore other options or to abandon this procedure entirely. We have developed a novel, technically facile, endoscopic approach to pyloromyotomy, and sought to assess the efficacy of this new approach compared to the standard surgical pyloromyotomy. METHODS: Patients who underwent MIE for cancer from 01/2010 to 12/2019 were identified from a prospectively maintained institutional database and were divided into two groups according to the pyloric drainage procedure: endoscopic or surgical pyloric drainage. 30-day outcomes (complications, length of stay, readmissions) and pyloric drainage-related outcomes [conduit distension/width, nasogastric tube (NGT) duration and re-insertion, gastric stasis] were compared between groups. RESULTS: 94 patients were identified of these 52 patients underwent endoscopic PM and 42 patients underwent surgical PM. The groups were similar with respect to age, gender and comorbidities. There were more Ivor-Lewis esophagectomies in the endoscopic PM group than the surgical PM group [45 (86%), 15 (36%) p < 0.001]. There was no significant difference in the rate of complications and readmissions. Gastric stasis requiring NGT re-insertion was rare in the endoscopic PM group and did not differ significantly from the surgical PM group (1.9-4.7% p = 0.58). CONCLUSIONS: Endoscopic pyloromyotomy using a novel approach is a safe, quick and reproducible technique with comparable results to a surgical PM in the setting of MIE.

RESUMO

BACKGROUND: Postoperative ambulation is an important tenet in enhanced recovery programs. We quantitatively assessed the correlation of decreased postoperative ambulation with postoperative complications and delays in gastrointestinal function. METHODS: Patients undergoing major abdominal surgery were fitted with digital ankle pedometers yielding continuous measurements of their ambulation. Primary endpoints were the overall and system-specific complication rates, with secondary endpoints being the time to first passage of flatus and stool, the length of hospital stay, and the rate of readmission. RESULTS: 100 patients were enrolled. We found a significant, independent inverse correlation between the number of steps on the first and second postoperative days (POD1/2) and the incidence of complications as well as the recovery of GI function and the likelihood of readmission (P < .05). POD2 step count was an independent risk factor for severe complications (P = .026). DISCUSSION: Digitally quantified ambulation data may be a prognostic biomarker for the likelihood of severe postoperative complications.

RESUMO

BACKGROUND: We have previously demonstrated that implementing an enhanced recovery protocol (ERP) improved outcomes after esophagectomy. We sought to examine if, after a decade of an established ERP, further improvements in postoperative outcomes could be made after continually optimizing and revising the pathway. METHODS: Patients undergoing esophagectomy for cancer from January 2019 to January 2020 were compared with our early-experience group within the initial ERP (June 2010-May 2011) and pre-ERP traditional care (June 2009-May 2010). The original ERP was initiated on June 2010 and underwent several revisions from 2014 to 2018, incorporating the following, amongst other elements: shorten the planned length of stay from 7 to 6 days, elimination of nasogastric tubes, use of soft closed-suction chest drains, and increased application of minimally invasive esophagectomy (MIE). Thirty-day outcomes (complications, length of stay, readmission) were compared for patients undergoing esophagectomy during the initial and most recent ERPs. RESULTS: Overall, 175 patients were identified; 47 underwent esophagectomy before ERP implementation (traditional care), 59 patients underwent esophagectomy after implementation of the original ERP, and 69 patients underwent esophagectomy after the most recent ERP (ERP 2.0). The groups were similar with respect to age, sex, and diagnosis. There were three times more MIEs in the ERP 2.0 group with a shorter median length of stay (7 [6-9] vs. 8 [7-17] vs. 10 [9-17]; p < 0.001) without impacting postoperative morbidity or readmission rate. CONCLUSION: Continued evaluation of institutional outcomes after esophagectomy should be performed to identify target areas for optimization and revision of established enhanced recovery protocols. ERPs are dynamic processes that can be further refined to yield greater improvements in outcomes.

RESUMO

INTRODUCTION: In primary Crohn's disease (CD), laparoscopic ileocolic resection has been shown to be both feasible and safe, and is associated with improved outcomes in terms of postoperative morbidity and length of hospital stay. However, it is unclear whether the laparoscopic approach can be routinely proposed as a safe procedure for patients with complex enterovisceral fistulas.The aim of this study is to assess the feasibility and safety of laparoscopic surgery for complex enterovisceral fistulas, and compare it with CD patients who underwent primary laparoscopic ileocolic resection. PATIENTS AND METHODS: All patients who underwent laparoscopic primary ileocolic resection (LICR) for complex enterovisceral fistulas between July 2006 and July 2017 were included. They were compared with all consecutive patients who underwent LICR for nonfistulizing CD in the same period of time. Patients with previous bowel resections or recurrent disease were excluded. RESULTS: Nineteen patients with 20 enterovisceral fistulas (group I) were compared with 61 patients who underwent LICR for nonfistulizing disease (group II). There were no differences between the groups in age, sex, preoperative body mass index, nutritional status, and American Society of Anesthesiology score. There was no conversion to open surgery in both groups.There were no significant differences between groups in terms of operative time [120 (range: 65 to 232) vs. 117 (range: 62 to 217) min, P=0.7], hospital stay [6 (5 to 8) vs. 7 (5 to 65) days, P=0.56], overall morbidity 26.3% versus 16.4% (P=0.33), major morbidity (Clavien-Dindo >3) 15.7% versus 10% (P=0.66) and reoperation rates 5.3% versus 4.9% (P=0.9). There was no mortality in both groups. CONCLUSIONS: Our experience shows that the laparoscopic approach for complex enterovisceral fistulas in selected CD patients is both feasible and safe in the hands of experienced inflammatory bowel disease surgeons with extensive expertise in laparoscopic surgery. Larger study cohorts are needed to confirm these findings.

RESUMO

BACKGROUND: Minimally invasive adrenalectomy has facilitated resection of resistant adrenal metastases. The adrenal gland may function as a sanctuary site for metastatic growth despite systemic therapy. The objective of the study was to assess the outcomes of selective minimally invasive adrenalectomy during immunotherapy. METHODS: Candidates included patients with adrenal metastases resistant to systemic therapy who underwent minimally invasive adrenalectomy. RESULTS: There were 15 patients undergoing 16 minimally invasive adrenalectomies. Patients received either immunotherapy or BRAF inhibition prior to surgery. The mean operative time was 130 min with a median length of hospital stay of 2 days. At a median follow up of 24 months, 7 patients have no evidence of disease, 6 patients had progression with eventual mortality, while another patients has stable disease with maintenance therapy. One was lost to follow up. CONCLUSION: Despite an increase in objective durable responses in metastatic melanoma, there is still some site-specific resistance in isolated areas like the adrenal where early minimally invasive adrenalectomy remains indicated.

RESUMO

INTRODUCTION: The management of peritoneal surface malignancies has changed dramatically. Moving, in less than two decades, from a nihilistic approach offering limited palliation and a short median survival into an aggressive surgical approach combining resection of all tumor deposits (cytoreductive surgery (CRS) combined with hyperthermic intra-peritoneal chemotherapy (HIPEC). This novel approach dramatically changed the outcome of this group of disorders offering a long term survival with curative intent to selected patients. The aim of the current review is to describe, based on current medical literature and our experience, current treatment options with CRS+HIPEC in various peritoneal surface malignancies of gastrointestinal origin, namely, colorectal cancer and appendiceal cancer, indications, technique, and outcomes.

RESUMO

BACKGROUND AND OBJECTIVE: Entero vesical fistulas (EVFs) are an uncommon complication mainly of diverticular disease (70%) and less commonly of Crohn's disease (10%). Only about 10% are caused by malignancies. At this time, it is unclear whether the laparoscopic approach can be routinely proposed as a safe procedure for patients with EVF. The aim of this study was to assess the feasibility and safety of laparoscopic surgery in the treatment of EVFs in patients with complicated diverticular and Crohn's disease. METHODS: All patients with the diagnosis of EVF who underwent laparoscopic surgery were identified from prospective collected data based in two institutions between 2007 and 2017. Patients with malignancy were excluded. Recorded parameters included operative time, conversion to open surgery, the presence of a protective loop ileostomy, perioperative complications, number of units of blood transfused, postoperative course, and histologic findings. RESULTS: Seventeen patients were included in the study: 10 patients with a colo-vesical fistula due to diverticular disease, and 7 patients with an ileo-vesical fistula due to Crohn's disease. There were no conversions to open surgery and none of the patients needed a protective ileostomy. The bladder was sutured in 12 patients (70%). No intra-operative complications were met, and no blood transfusions were needed; there were no anastomotic leaks, nor mortality in both groups. CONCLUSIONS: The laparoscopic approach for benign EVF in selected patients is both feasible and safe in the hands of experienced surgeons with extensive expertise in laparoscopic surgery.

RESUMO

BACKGROUND: Recent studies have analyzed risk factors associated with complications after gastric cancer surgery using the Clavien-Dindo classification (CD). However, they have been based on Asian population cohorts (Chinese, Japanese, Korean). OBJECTIVES: To prospectively analyze all post-gastrectomy complications according to severity using CD classification and identify postoperative risk factors and complications. METHODS: We analyzed all gastrectomies for gastric cancer performed 2009-2014. Recorded parameters included demographic data, existing co-morbidities, neo-adjuvant treatment, intra-operative findings, postoperative course, and histologic findings. Postoperative complications were graded using CD classification. RESULTS: The study comprised 112 patients who underwent gastrectomy. Mean age was 64.8 ± 12.8 years; 53 patients (47%) underwent gastrectomy, 37 (34%) total gastrectomy, and 22 (19%) total extended gastrectomy. All patients had D2 lymphadenectomy. The average number of retrieved lymph nodes was 35 ± 17. Severe complication rate (≥ IIIa) was 14% and mortality rate was 1.8%. In a univariate analysis, age > 65 years; ASA 3 or higher; chronic renal failure; multi-organ resection; and tumor, node, and metastases (TNM) stage ≥ IIIc were found to be significantly associated with CD complication grade > III (P = 0.01, P = 0.05, P = 0.04, P = 0.04, and P = 0.01, respectively). Multivariate regression analysis revealed advanced stage (≥ IIIc) and age > 65 years to be significant independent risk factors (P < 0.05). CONCLUSIONS: Age > 65 and advanced stage (≥ IIIc) were the primary risk factors for complications of grade > III according to the CD classification following gastrectomy for gastric cancer.

RESUMO

BACKGROUND: Jejunal diverticulitis is a rare clinical entity often overlooked by physicians as a cause for abdominal pain. Although diagnostic capabilities improved in recent years, there is little data about diverticular disease in the proximal small bowel. The aim of this study is to present the clinical course and management in a series of eight cases of jejunal diverticulitis and possible therapeutic interventions. METHODS: A cohort retrospective analysis of all patients admitted for acute jejunal diverticulitis between January 2010 and June 2015 was conducted. Patient demographics, clinical, and surgical outcome were recorded and analyzed. RESULTS: Eight patients were admitted for acute jejunal diverticulitis with a mean age of 72.1 (range 55-87) years. Clinical presentation included six patients (75%) with a sealed perforation and only one patient demonstrated distant pneumoperitoneum. All patients were treated initially without surgery and only one patient required surgery because of diverticular complications. Recurrent episodes occurred in two patients (25%). Colonoscopy was performed in all patients after hospitalization that revealed large bowel diverticulosis in all patients (100%). Median follow-up was 8.2 months (3-15 months). CONCLUSION: Jejunal diverticulitis can be initially treated conservatively but complicated disease should be considered for surgical management. Further study is required on the relationship between small and large bowel diverticulosis.
