RESUMO

BACKGROUND: Patients undergoing high-risk surgery are at a risk of sudden deterioration of their health. This study aimed to examine the feasibility of the development of two patient decision aids (PtDAs) to assist patients undergoing high-risk surgeries in informed decision-making about their medical care in a crisis. METHODS: This field testing implemented two PtDAs that met the international criteria developed by the researchers for patients before surgery. Study participants were patients scheduled to be admitted to the intensive care unit after surgery at one acute care hospital in Japan and their families. The study used a mixed-methods approach. The primary outcome was patients' decision satisfaction evaluated by the SURE test. Secondary outcomes were the perception of the need to discuss advance care planning (ACP) before surgery and mental health status. The families were also surveyed on their confidence in proxy decision-making (NRS: 0-10, quantitative data). In addition, interviews were conducted after discharge to assess the acceptability of PtDAs. Data were collected before (preoperative outpatients, baseline: T0) and after providing PtDAs (in the hospital: T1) and following discharge (T2, T3). RESULTS: Nine patients were enrolled, of whom seven agreed to participate (including their families). The SURE test scores (mean ± SD) were 2.1 ± 1.2 (T0), 3.4 ± 0.8 (T2), and 3.9 ± 0.4 (T3). The need to discuss ACP before surgery was 8.7 ± 1.3 (T1) and 9.1 ± 0.9 (T2). The degree of confidence in family surrogate decision-making was 6.1 ± 2.5 (T0), 7.7 ± 1.4 (T1), and 8.1 ± 1.5 (T2). The patients reported that using PtDAs provided an opportunity to share their thoughts with their families and inspired them to start mapping their life plans. Additionally, patients wanted to share and discuss their decision-making process with medical professionals after the surgery. CONCLUSIONS: PtDAs supporting ACP in patients undergoing high-risk surgery were developed, evaluated, and accepted. However, they did not involve any discussion of patients' ACP treatment wishes with their families. Medical providers should be coached to provide adequate support to patients. In the future, larger studies evaluating the effectiveness of PtDAs are necessary.

RESUMO

Current algorithms for surveillance of patients with esophageal adenocarcinoma (EAC) after chemoradiation and surgery (trimodality therapy [TMT]) remain empiric. The authors hypothesized that the frequency, type, and timing of relapses after TMT would be highly associated with surgical pathology stage (SPS), and therefore SPS could be used to individualize the surveillance strategy. Between 2000 and 2010, 518 patients with EAC were identified who underwent TMT at The University of Texas MD Anderson Cancer Center and were frequently surveyed. Frequency, type, and timing of the first relapse (locoregional and/or distant) were tabulated according to SPS. Standard statistical approaches were used. The median follow-up time after esophageal surgery was 55.4 months (range, 1.0-149.2 months). Disease relapse occurred in 215 patients (41.5%). Higher SPS was associated with a higher rate of relapse (0/I vs II/III, P≤.001; 0/I vs II, P=.002; SPS 0/I vs III, P≤.001; and SPS II vs III, P=.005) and with shorter time to relapse (P<.001). Irrespective of the SPS, approximately 95% of all relapses occurred within 36 months of surgery. The 3- and 5-year overall survival rates were shorter for patients with a higher SPS than those with a lower SPS (0/I vs II/III, P≤.001; 0/I vs II, P≤.001; 0/I vs III, P≤.001; and II vs III, P=.014). The compelling data show an excellent association between SPS and frequency/type/timing of relapses after TMT in patients with EAC. Thus, the surveillance strategy can potentially be customized based on SPS. These data can inform a future evidence-based surveillance strategy that can be efficient and cost-effective.

RESUMO

BACKGROUND: It is unclear whether patients undergoing trimodality therapy (TMT) should be screened or surveyed for brain metastases. METHODS: We retrospectively analyzed esophageal cancer (EC) patients who underwent TMT between the years 2000 and 2010. All were systematically staged and surveyed but none had screening or surveillance brain imaging. RESULTS: The median follow-up time for 518 patients was 29.3 months (range 1-149.2); all patients had adenocarcinoma of the esophagus. Of 188 (36.3%) patients who developed distant metastases, 20 (10.6% of 188 patients or 3.9% of 518 patients) had brain metastases. A higher baseline clinical stage (stage III or IVa) was associated with brain metastases. Most (90%) patients with brain metastases were diagnosed within 24 months of surgery. Sixteen patients had central nervous system symptoms at diagnosis. Twelve (60%) patients had solitary metastasis and 8 (40%) patients had multiple metastases. Although 17 patients received therapy for brain metastases, the median overall survival time of 20 patients was only 10.5 months (95% CI 6.6-14.0). CONCLUSION: After TMT, 3.9% of EC patients developed brain metastases and their prognosis was poor. Our data suggest that screening and/or surveillance for brain metastases in the EC population undergoing TMT is not warranted.

RESUMO

BACKGROUND: Trimodality therapy (TMT; chemoradiation plus surgery) has level-1 evidence for survival advantage for TMT-eligible esophagogastric cancer patients. Some patients, however, decline surgery after preoperative chemoradiation. The question of which patient should have esophagectomy and which one should not is unlikely to be answered by a prospective comparison; therefore, we matched the clinical covariates of several patients who had surgery with those who declined surgery (DS). METHODS: Between 2002 and 2011, we identified 623 patients in our databases. Of 623 patients, 244 patients had TMT and 61 TMT-eligible patients were in the DS group. Using the propensity-score method, we matched 16 covariates between 36 DS patients and 36 TMT patients. RESULTS: Baseline characteristics between the two groups were balanced (p = NS). The median overall survival times were: 57.9 months (95% CI: 27.7 to not applicable, NA) for the DS group and 50.8 months (95% CI: 30.7 to NA) for the TMT group (p = 0.28). The median relapse-free survival times were: 18.5 (95% CI: 11.5-30.4) for the DS group and 26.5 months (95% CI: 15.5-NA) for the TMT group (p = 0.45). Eleven (31%) of 36 patients in the DS group had salvage surgery. CONCLUSIONS: Our results are intriguing but skewed by the patients who had salvage surgery in the DS group. Until highly reliable predictive models are developed for esophageal preservation, TMT must be encouraged for all TMT-eligible gastroesophageal cancer patients.

RESUMO

Gastric cancer confers a poor prognosis even when diagnosed as localized disease. Multimodality therapy improves the cure rate of patients with localized cancer. However, adjunctive therapeutic approaches differ in different regions of the world. This review focuses on the current standards and unresolved issues based on updated literature on therapy for localized gastric cancer. In the USA, the Intergroup 0116 trial established the use of postoperative chemoradiotherapy as a standard for patients who have surgery first for treatment of gastric cancer. In Europe, the MAGIC trial investigating perioperative chemotherapy demonstrated a survival benefit for gastric cancer patients. Finally, in Asia, the ACTS-GC and CLASSIC trials investigating postoperative chemotherapy established this as the standard of care after primary surgery that included D2 dissection. It is clear, however, that surgery alone is insufficient to achieve the highest possible cure rates.

RESUMO

Ramucirumab (IMC-1121B) is a fully humanized monoclonal antibody that binds to VEGFR2 and can inhibit angiogenesis, a quintessential mechanism for promoting tumor growth and metastasis. Several antiangiogenesis agents are already approved for cancer therapy; however, ramucirumab's selectivity for VEGFR2 makes it interesting. The selectivity of an agent can improve safety and efficacy. This article describes the mechanism of action, pharmacokinetics, safety and clinical trial results of ramucirumab with particular emphasis on gastric cancer.

RESUMO

The aim of the present study was to investigate the significance of appendicoliths as an exacerbating factor of acute appendicitis using multivariate analysis. A total of 254 patients with pathologically proved acute appendicitis were enrolled in this retrospective study (male, 51 %; mean age, 40.1 years; range, 15-91 years). Two radiologists performed a consensus evaluation of preoperative CT images for the presence of appendicoliths in consensus. When there were appendicoliths, they assessed the number and location of appendicoliths, and measured the longest diameter of the largest appendicolith. Pathological diagnosis was used for the reference standard. The relationships of appendicoliths to gangrenous appendicitis and to perforated appendicitis were each assessed with multiple logistic regression models, which were adjusted for demographic and clinical characteristics of patients. Significant relationships were identified between gangrenous appendicitis and the presence of appendicoliths (OR, 2.2; 95 % CI, 1.2-4.0), the largest appendicolith more than 5 mm in the longest (OR, 3.0; 95 % CI, 1.6-5.7), and location of an appendicolith at the root of the appendix (OR, 2.0; 95 % CI, 1.1-3.8). Among the CT characteristics, the location of an appendicolith at the root of the appendix only showed significant relationship with perforated appendicitis (OR, 4.5; 95 % CI, 1.4-15.4). Size of the largest appendicolith and location of appendicoliths at the root of the appendix are exacerbating factors of acute appendicitis.

RESUMO

Extraperitoneal mesh repair for ventral hernia has garnered attention and its rate has been increasing due to concerns for the potential complications of intraperitoneal mesh repair. Recently, robotic-assisted ventral hernia repair is highlighted as a solution to the technically demanding nature of laparoscopic transabdominal or enhanced-view totally extraperitoneal retrorectus ventral hernia repair. A 78-year-old man, who had undergone robot-assisted radical prostatectomy 10 months earlier, presented with an incisional hernia of European Hernia Society Classification M3W2, length 4 cm, width 5 cm with rectus diastasis. A right single-docking robotic-assisted transabdominal retrorectus repair was performed using a 21 by 14 cm self-gripping mesh and anterior wall reconstruction was done by 0 barbed nonabsorbable running suture. There were no complications and recurrence observed during a 7 months postoperative period. Single-docking robotic-assisted transabdominal retrorectus repair was considered a good option for midline moderate-size incisional hernias from the point of view of the ease of suturing, adequateness of dissection and prevention of bowel injury.

RESUMO

BACKGROUND: For patients with localized esophageal cancer (EC) who can withstand surgery, the preferred therapy is chemoradiation followed by surgery (trimodality). However, after achieving a clinical complete response [clinCR; defined as both post-chemoradiation endoscopic biopsy showing no cancer and physiologic uptake by positron emission tomography (PET)], some patients decline surgery. The literature on the outcome of such patients is sparse. METHOD: Between 2002 and 2011, we identified 622 trimodality-eligible EC patients in our prospectively maintained databases. All patients had to be trimodality eligible and must have completed preoperative staging after chemoradiation that included repeat endoscopic biopsy and PET among other routine tests. RESULTS: Out of 622 trimodality-eligible patients identified, 61 patients (9.8%) declined surgery. All 61 patients had a clinCR. The median age was 69 years (range 47-85). Males (85.2%) and Caucasians (88.5%) were dominant. Baseline stage was II (44.2%) or III (52.5%), and histology was adenocarcinoma (65.6%) or squamous cell carcinoma (29.5%). Forty-two patients are alive at a median follow-up of 50.9 months (95% CI 39.5-62.3). The 5-year overall and relapse-free survival rates were 58.1 ± 8.4 and 35.3 ± 7.6%, respectively. Of 13 patients with local recurrence during surveillance, 12 had successful salvage resection. CONCLUSION: Although the outcome of 61 EC patients with clinCR who declined surgery appears reasonable, in the absence of a validated prediction/prognosis model, surgery must be encouraged for all trimodality-eligible patients.

RESUMO

BACKGROUND: In patients with localized gastric cancer (LGC) who are unfit for surgery, decline surgery, or have unresectable cancer, chemoradiotherapy may provide palliation; however, data in the literature are sparse. METHODS: We identified 66 LGC patients who had definitive chemoradiation but no surgery. All patients had baseline and postchemoradiation staging including an endoscopic biopsy. Multiple statistical methods were used to analyze outcomes. RESULTS: Most patients were men and most had stage III or IV cancer. Five patients were surgery eligible but declined to have surgery. The median follow-up time was 33.9 months (95% CI 18.3-49.6). The median survival time (MST) for 66 patients was only 14.5 months (95% CI 10.8-19.7) and the median relapse-free survival (RFS) was 5.03 months (95% CI 4.67-6.40). The estimated overall survival (OS) and RFS rates at 3 years were 22.6% (95% CI 13.7-37.3) and 7.7% (95% CI 3.2-18.6), respectively. Twenty-three (35%) patients who achieved a clinical complete response (cCR; negative postchemoradiation biopsy and no progression by imaging) fared better than those who achieved less than cCR (

RESUMO

We performed laparoscopic surgery for three cases of colorectal cancer using an 8K ultra-high-definition endoscopic system, which offers 16-fold higher resolution than the current 2K high-definition endoscope. The weight of the camera has been successfully reduced to 370 g. To maximize the advantages of the 8K ultra-high-definition endoscope, surgery was performed by darkening the room and placing a large 85-in. display as close to the surgeon as possible. As a result, the autonomic nerve was preserved, and the membrane structure could be clearly observed. Moreover, we were able to feel the stereoscopic effect near the 3-D image. This suggests the possibility of improved curability and function preservation with the 8K endoscope. Although there are some disadvantages that need to be overcome, the 8K ultra-high-definition endoscope will surely contribute to further progress in laparoscopic surgery.

RESUMO

INTRODUCTION: The aim of this study was to introduce and examine a modified mechanical end-to-side esophagogastrostomy method ("reverse-Tornado" anastomosis) in laparoscopy-assisted proximal gastrectomy. METHODS: Five patients with gastric cancer who underwent laparoscopy-assisted proximal gastrectomy were analyzed retrospectively. Esophagogastrostomy in the anterior wall was performed in three patients, and esophagogastrostomy in the posterior wall was performed in two patients. Clinicopathological features, operative outcomes (operative time, operative blood loss), and postoperative outcomes (complications, postoperative hospital stay, reflux esophagitis) were evaluated. RESULTS: Operative time was normal (278 min). There was no marked operative blood loss, postoperative complications, prolonged hospital stay, or reflux esophagitis. CONCLUSION: Esophagogastrostomy was completed in a normal time with reverse-Tornado anastomosis. This method can be safe and can enable good postoperative quality of life.

RESUMO

PURPOSE: Patients with esophageal carcinoma (EC) who are treated with definitive chemoradiotherapy (bimodality therapy [BMT]) experience frequent relapses. In a large cohort, we assessed the timing, frequency, and types of relapses during an aggressive surveillance program and the value of the salvage strategies. PATIENTS AND METHODS: Patients with EC (N = 276) who received BMT were analyzed. Patients who had surgery within 6 months of chemoradiotherapy were excluded to reduce bias. We focused on local relapse (LR) and distant metastases (DM) and the salvage treatment of patients with LR only. Standard statistical methods were applied. RESULTS: The median follow-up time was 54.3 months (95% CI, 48.4 to 62.4). First relapses included LR only in 23.2% (n = 64), DM with or without LR in 43.5% (n = 120), and no relapses in 33.3% (n = 92) of patients. Final relapses included no relapses in 33.3%, LR only in 14.5%, DM only in 15.9%, and DM plus LR in 36.2% of patients. Ninety-one percent of LRs occurred within 2 years and 98% occurred within 3 years of BMT. Twenty-three (36%) of 64 patients with LR only underwent salvage surgery, and their median overall survival was 58.6 months (95% CI, 28.8 to not reached) compared with those patients with LR only who were unable to undergo surgery (9.5 months; 95% CI, 7.8 to 13.3). CONCLUSION: Unlike in patients undergoing trimodality therapy, for whom surveillance/salvage treatment plays a lesser role,(1) in the BMT population, approximately 8% of all patients (or 36% of patients with LR only) with LRs occurring more than 6 months after chemoradiotherapy can undergo salvage treatment, and their survival is excellent. Our data support vigilant surveillance, at least in the first 24 months after chemotherapy, in these patients.

RESUMO

Gastric cancer (GC) is a major health burden throughout the world, especially in certain endemic regions. GC is commonly diagnosed at an advanced stage because of the lack of early detection strategies and is usually associated with a dismal outcome. For patients with localized GC (LGC), surgery is the best cure: cure rates are highly associated with the surgical pathology stage. Adjunctive therapies improve the cure rates by about an additional 10%. Therefore, a multimodality approach is highly recommended for all patients with LGC. This article highlights some of the therapeutic advances made against GC and features important ongoing trials.

RESUMO

Esophageal cancer management is based on baseline clinical stage, location of the tumor, and associated comorbid conditions. In patients with localized esophageal cancer (LEC) with technically resectable tumors and who are medically fit for surgery, the current recommendation is trimodality therapy (chemoradiation followed by surgery). Bimodality therapy (definitive chemoradiation) is reserved for patients with cervical esophageal tumors, technically unresectable tumors, for patients who cannot be recommended surgery due to medical comorbidities, or those who decline surgery. Prospective data from 2 studies suggest that definitive chemoradiation may be sufficient for LEC with squamous cell histology; a definite answer, however, is unclear.

RESUMO

PURPOSE: The primary purpose of surveillance of patients with esophageal adenocarcinoma (EAC) and/or esophagogastric junction adenocarcinoma after local therapy (eg, chemoradiotherapy followed by surgery or trimodality therapy [TMT]) is to implement a potentially beneficial salvage therapy to overcome possible morbidity/mortality caused by locoregional failure (LRF). However, the benefits of surveillance are not well understood. We report on LRFs and salvage strategies in a large cohort. PATIENTS AND METHODS: Between 2000 and 2010, 518 patients with EAC who completed TMT were analyzed for the frequency of LRF over time and salvage therapy outcomes. Standard statistical techniques were used. RESULTS: For 518 patients, the median follow-up time was 29.3 months (range, 1 to 149 months). Distant metastases (with or without LRF) occurred in 188 patients (36%), and LRF only occurred in 27 patients (5%). Eleven of 27 patients had lumen-only LRF. Most LRFs (89%) occurred within 36 months of surgery. Twelve patients had salvage chemoradiotherapy, but only five survived more than 2 years. Four patients needed salvage surgery, and three who survived more than 2 years developed distant metastases. The median overall survival of 27 patients with LRF was 17 months, and 10 patients (37%) survived more than 2 years. Thus, only 2% of all 518 patients benefited from surveillance/salvage strategies. CONCLUSION: Our surveillance strategy, which is representative of many others currently being used, raises doubts about its effectiveness and benefits (along with concerns regarding types and times of studies and costs implications) to patients with EAC who have LRF only after TMT. Fortunately, LRFs are rare after TMT, but the salvage strategies are not highly beneficial. Our data can help develop an evidence-based surveillance strategy.

RESUMO

Paraneoplastic neurological syndromes (PNS) are associated with small-cell lung cancer, breast and gynecological cancers. We describe a gastric neoplasm presented with neurological symptoms. A 74-year-old male presented with tonic-clonic seizures. Initial investigations were normal; however, brain magnetic resonance imaging showed abnormal signal intensity in the hippocampi. A diagnosis of PNS was suspected. The patient was then diagnosed with a gastric neuroendocrine carcinoma with N-type voltage-gated calcium channel antibodies. The neurological impairments improved after the primary was resected and the patient remains free of cancer and paraneoplastic syndrome. We reviewed 10 cases of PNS associated with gastric cancer and found several characteristics: (1) older men, (2) neuroendocrine component or predominance, (3) oncological outcome for patients with PNS is better than for patients without PNS, and (4) neurological impairment is diagnosed 6 months prior to the diagnosis of gastric malignancy. In conclusion, elderly men with symptoms suggestive of PNS should be investigated for a gastric neuroendocrine malignancy.

RESUMO

BACKGROUND: The presence of malignant lymph nodes (+ypNodes) in the surgical specimen after preoperative chemoradiation (trimodality) in patients with oesophageal cancer (EC) portends a poor prognosis for overall survival (OS) and disease-free survival (DFS). Currently, none of the clinical variables highly correlates with +ypNodes. We hypothesised that a combination of clinical variables could generate a model that associates with high likelihood of +ypNodes after trimodality in EC patients. METHODS: We report on 293 consecutive EC patients who received trimodality therapy. A multivariate logistic regression analysis that included pretreatment and post-chemoradiation variables identified independent variables that were used to construct a nomogram for +ypNodes after trimodality in EC patients. RESULTS: Of 293 patients, 91 (31.1%) had +ypNodes. OS (p=0.0002) and DFS (p<0.0001) were shorter in patients with +ypNodes compared to those with -ypNodes. In multivariable analysis, the significant variables for +ypNodes were: baseline T-stage (odds ratio [OR], 7.145; 95% confidence interval [CI], 1.381-36.969; p=0.019), baseline N-stage (OR, 2.246; 95% CI, 1.024-4.926; p=0.044), tumour length (OR, 1.178; 95% CI, 1.024-1.357; p=0.022), induction chemotherapy (OR, 0.471; 95% CI, 0.242-0.915; p=0.026), nodal uptake on post-chemoradiation positron emission tomography (OR, 2.923; 95% CI, 1.007-8.485; p=0.049) and enlarged node(s) on post-chemoradiation computerised tomography (OR, 3.465; 95% CI, 1.549-7.753; p=0.002). The nomogram after internal validation using the bootstrap method (200 runs) yielded a high concordance index of 0.756. CONCLUSION: Our nomogram highly correlates with the presence of +ypNodes after chemoradiation, however, considerably more refinement is needed before it can be implemented in the clinic.

RESUMO

Objective. Mesorectal excision corresponding to the location of a tumor, termed tumor-specific mesorectal excision (TSME), is commonly performed for resection of upper rectal cancer. We devised a new laparoscopic procedure for sufficient TSME with rectal transection followed by mesorectal excision. Operative Technique. After mobilization of the sigmoid colon and ligation of inferior mesenteric vessels, we dissected the mesorectum along the layer of the planned total mesorectal excision. The rectal wall was carefully separated from the mesorectum at the appropriate anal side from the tumor. After the rectum was isolated and transected using an endoscopic linear stapler, the rectal stump drew immediately toward the anal side, enabling the mesorectum to be identified clearly. In this way, sufficient TSME can be performed easily and accurately. This technique has been successfully conducted on 19 patients. Conclusion. This laparoscopic technique is a feasible and reliable procedure for achieving sufficient TSME.
