RESUMO

Background: The development and improved response to chemotherapy has resulted in a survival benefit of conversion surgery (CS) for advanced gastric cancer (GC). However, this benefit is limited in some cases, such as in those with very early recurrence (VER). This study investigated the relationship between outcome and clinicopathological characteristics after CS for stage IV GC, and the risk factors for VER after CS. Methods: We retrospectively studied 184 patients with stage IV GC who initially underwent chemotherapy, including 36 patients who underwent CS between May 2007 and January 2022. We evaluated the long-term outcome after CS for stage IV GC and the clinicopathological characteristics of the patients who underwent CS. Results: Median survival times (MSTs) in the chemotherapy alone and CS groups were 13.4 and 36.5 months, respectively (p < 0.0001). Of the 27 patients who underwent R0 resection, 22 remained free of early recurrence and five experienced VER. MSTs in the VER and free of early recurrence groups were 15.2 and 44.1 months, respectively (p < 0.0001). Significantly more patients had liver metastasis before initial treatment in the VER group than in the FER group (p = 0.016). There were more patients with preoperative PNI <40 in the VER group (p = 0.046). Conclusion: CS is an effective treatment for stage IV GC, but VER is associated with poor prognosis. We need to carefully consider the indications for CS, especially for patients with poor nutritional status and liver metastases.

RESUMO

PURPOSE: Textbook outcome (TO) is a composite quality measurement of short-term outcomes for evaluating surgical procedures. We investigated whether TO can be used to predict outcomes after curative gastric cancer (GC) surgery in older adults. METHODS: We retrospectively analyzed 492 consecutive patients who underwent curative gastrectomy for GC from 2005 to 2017. Among these, 141 advanced-age patients were eligible. The patients were divided into two groups: those who achieved TO (a-TO group) and those who failed to achieve TO (f-TO group). In accordance with previous reports, TO consisted of eight metrics. We evaluated the association between TO and long-term survival. RESULTS: TO was achieved 73 (52%) patients. The patients in the f-TO group had a significantly higher body mass index (P = 0.01), longer surgery time (P = 0.03), and more blood loss (P = 0.001). The metric with the lowest achievement rate was "no postoperative severe complication." The patients in the f-TO group had significantly shorter overall survival than those in the a-TO group (P = 0.03). Multivariable Cox regression analyses of overall survival revealed that an American Society of Anesthesiologists physical status classification of 3 (hazard ratio [HR], 3.28; 95% confidence interval [CI], 1.79-5.98; P < 0.0001) and f-TO (HR, 1.92; 95% CI, 1.09-3.39; P = 0.02) were significantly associated with poor overall survival. CONCLUSION: TO can be used to predict outcomes after curative GC surgery in patients of advanced age.

RESUMO

PURPOSE: Textbook outcome (TO) has been used to define achievement of multiple "ideal" or "optimal" surgical and postoperative quality measures from the patient's perspective. However, TO has not been reported for their impact on survival in elderly, including CRC surgery. This study determined whether TO is associated with long-term outcomes after curative colorectomy in patients with colorectal cancer (CRC). METHODS: Patient who underwent curative surgery over 75 years old for CRC between March 2005 and December 2016. TO included five separate parameters: surgery within 6 weeks, radical resection, Lymph node (LN) yield ≥ 12, no stoma, and no adverse outcome. When all 5 short-term quality of care parameters were realized, TO was achieved (TO). If any one of the 5 parameters was not met, the treatment was not considered TO (nTO). RESULTS: TO was realized in 80 patients (43.0%). Differences in surgical-related characteristics and pathological characteristics according to TO had no statistically significant differences in baseline characteristics, except for Lymph node dissection. The Kaplan-Meier curves for OS and RFS association between TO and nTO had significantly poor 5-year OS and 5-year RFS compared with the TO groups (OS, 77.8% vs. 60.8%, P < 0.01; RFS, 69.6% vs. 50.8%, P = 0.01). In the multivariate analysis, nTO was an independent predictive factor for worse OS (HR, 2.04; 95% confidence interval (CI), 1.175-3.557; P = 0.01) and RFS (HR, 1.72; 95% CI, 1.043-2.842; P = 0.03). CONCLUSIONS: TO can be a useful predictor for postoperative morbidity and prognosis after curative colorectomy for CRC.

RESUMO

BACKGROUND: Increased 18F-fluorodeoxyglucose (FDG) uptake in the bone marrow (BM) on positron emission tomography/computed tomography (PET/CT) clinically reflects increased BM metabolism owing to systemic inflammation, bacterial infection, anemia, and cytokine-producing tumors. The association between FDG uptake in the BM and prognosis after esophagectomy for esophageal cancer has not been investigated. METHODS: This study included 651 patients who underwent PET/CT before any treatment and McKeown esophagectomy for esophageal cancer between June 2007 and August 2021. The pretreatment degree of FDG uptake in the BM was evaluated using a visual assessment criterion. Patients were divided into low- and high-FDG uptake groups. We retrospectively investigated whether the degree of FDG uptake in the BM was associated with clinicopathological and surgical backgrounds, blood parameters, and prognosis. RESULTS: High FDG uptake in the BM was significantly associated with elevated white blood cell and neutrophil counts, increased C-reactive protein levels, decreased hemoglobin, serum albumin, and total cholesterol levels. High FDG uptake in the BM was an independent predictor of worse overall survival in clinical stages 0-II esophageal cancer (hazard ratio, 2.27; 95% confidence interval, 1.097-4.695; P = 0.027). Worse overall survival was also associated with advanced age, low American Society of Anesthesiologists physical status, an advanced clinical stage, and high intraoperative blood loss. CONCLUSION: Increased FDG uptake in the BM on pretreatment PET/CT may be a surrogate indicator of various clinically disadvantageous backgrounds and may act as a predictor of poor prognosis after esophageal cancer surgery.

RESUMO

BACKGROUND: The Clinical Frailty Scale (CFS) is a simple and validated tool for assessing frailty, and higher CFS scores are correlated with worse perioperative outcomes after cardiovascular surgery. However, the relationship between the CFS scores and postoperative outcomes after esophagectomy remain unclear. METHODS: We retrospectively analyzed data from 561 patients with esophageal cancer (EC) who underwent resection from August 2010 to August 2020. We defined a CFS score of ≥4 as indicative of frailty; thus, patients were classified into frail patients (CFS scores of ≥4) and non-frail patients (CFS scores of ≤3). The Kaplan-Meier method was used to describe the overall survival (OS) distributions with the log-rank test. RESULTS: Of the 561 patients, 90 (16%) had frailty and 471 (84%) did not. Frail patients had a significantly older age, lower body mass index, higher American Society of Anesthesiologists physical status classification, and greater cancer progression than non-frail patients. The 5-year survival rate was 68% in non-frail patients and 52% in frail patients. OS was significantly shorter in frail than non-frail patients (p = 0.017 by log-rank test). In particular, OS was significantly shorter in frail patients with clinical stage I-II EC (p = 0.0024 by log-rank test) but was not correlated with frailty in patients with clinical stage III-IV EC (p = 0.87 by log-rank test). CONCLUSIONS: Preoperative frailty was associated with shorter OS after resection of EC. The CFS score may be a prognostic biomarker for patients with EC, especially early-stage EC.

RESUMO

BACKGROUND: Seroma/hematoma formation is the most common postoperative complication after laparoscopic inguinal hernia repair. The occurrence of seroma/hematoma remains unclear. The aim of this study was to determine the risk factors for seroma/hematoma formation after transabdominal preperitoneal patch plasty (TAPP). METHODS: The study enrolled 359 groin hernia patients treated by TAPP at Kumamoto Medical Center between 2014 and 2019. The primary outcome was risk factors for postoperative seroma/hematoma formation after TAPP. The secondary outcomes included recurrence of hernia, postoperative complications, and hospital stay. RESULTS: Among the 359 patients, the incidence rate of seroma/hematoma was 16% (n = 69 patients), and the recurrence rate was 0.3% (n = 1 patient, both sides). In total, there were 452 lesions. Japan Hernia Society (JHS) type II was present in 23% (n = 106) of the total cases but was significantly more common in the postoperative seroma/hematoma group (40%; P = 0.0082). Meanwhile, JHS type I-3 comprised 27% of the total JHS type I group but was significantly higher in the postoperative seroma/hematoma JHS type I group (40%; P = 0.016). Compared with JHS type I, the multivariable odds ratio for postoperative seroma/hematoma formation in JHS type II was 2.77 (95% CI 1.54-4.95). Compared with JHS grade 1/2, the multivariable odds ratio for postoperative seroma/hematoma formation in JHS grade 3 was 2.27 (95% CI 1.28-4.03). CONCLUSIONS: Internal inguinal hernia and hernia size ≥ 3 cm were considered risk factors for postoperative seroma/hematoma formation after TAPP.

RESUMO

BACKGROUND: Radiofrequency ablation (RFA) is widely used as a minimally invasive treatment for hepatocellular carcinoma (HCC). RFA has a low risk of complications, especially compared with liver resection. Nevertheless, various complications have been reported after RFA for HCC; however, diaphragmatic hernia (DH) is extremely rare. CASE PRESENTATION: A 78-year-old man underwent thoracoscopic RFA for HCC located at the medial segment adjacent to the diaphragm approximately 7 years before being transported to the emergency department due complaints of nausea and abdominal pain. Computed tomography revealed a prolapsed small intestine through a defect in the right diaphragm, and emergency surgery was performed. The cause of diaphragmatic hernia was the scar of RFA. We confirmed that the small intestine had prolapsed into the right diaphragm, and we resected the necrotic small intestine and repaired the right diaphragm. Herein, we report a case of ileal strangulation due to diaphragmatic hernia after thoracoscopic RFA. CONCLUSIONS: Care should be taken when performing thoracoscopic RFA, especially for tumors located on the liver surface adjacent to the diaphragm. Patients should be carefully followed up for possible DH, even after a long postoperative interval.

RESUMO

BACKGROUND: Solitary fibrous tumor (SFT) is a relatively rare mesenchymal tumor that mainly affects adults. Its prognosis is good after curative resection, but distant recurrences after 10 years or longer have been reported. Recurrent SFT usually arises as a local lesion; distant metastasis is rarely reported. Here, we report lung metastases that recurred a decade after excising a retroperitoneal primary SFT. CASE PRESENTATION: A 44-year-old woman had an SFT resected from her right retroperitoneum at our hospital. Ten years later, at age 54, she underwent a lung resection after CT showed three suspected metastases in her left lung. All three were histologically diagnosed as lung metastases from the retroperitoneal SFT. However, whereas the primary SFT had 1-2 mitotic cells/10 high power fields (HPF), the metastatic lesion increased malignancy, at 50/10 HPF. CONCLUSION: Patients who have had resected SFTs should be carefully followed up, as malignancy may change in distant metastasis, as in this case.

RESUMO

BACKGROUND: Solid pseudopapillary neoplasm of the pancreas is a rare tumor in young women, metastasizing in only 5-15% of cases, and most commonly to the liver. Although treatment guidelines have not been established, surgical resection is usually performed. We report a rare case of repeat hepatectomy for liver metastases after distal pancreatectomy with solid pseudopapillary neoplasm. CASE PRESENTATION: The patient was a 71-year-old woman who underwent distal pancreatectomy for solid pseudopapillary neoplasm, and liver metastasis occurred 4 years after the first surgery. Partial liver resection was performed for four liver metastases, and histopathological examination revealed a diagnosis of liver metastasis from solid pseudopapillary neoplasm. However, 18 months later, liver metastases were detected again; three tumors were identified, and partial resection was performed, which has provided 18 months' recurrence-free survival. CONCLUSIONS: Long-term prognosis can be expected following R0 resection for resectable liver metastasis from solid pseudopapillary neoplasm.

RESUMO

BACKGROUND/AIM: Emergency surgery for colorectal cancer (CRC) is a high-risk procedure with high morbidity and mortality rates, especially for older patients. The relationship between patient age status and long-term outcomes is unclear. We hypothesize that patient age might be associated with long-term outcomes in patients with CRC who undergo emergency surgery. PATIENTS AND METHODS: Utilizing a database of CRC patients who received emergency surgery, we examined the prognostic association of patient age. RESULTS: The ≥80-years group was significantly associated with American Society of Anesthesiologists (ASA) physical status, bowel obstruction, N stage, shorter operating time, and less adjuvant chemotherapy (all p<0.03); and also, with shorter recurrence-free survival [multivariable hazard ratio, 2.79; 95% confidence interval, 1.13-7.21; p=0.026]. ASA status and adjuvant chemotherapy were significantly associated with recurrence-free survival (all p<0.03). CONCLUSION: Advanced age is associated with shorter recurrence-free survival in CRC patients who undergo emergency surgery.

RESUMO

AIM: With population aging, the number of frail patients with colorectal cancer has increased. The Clinical Frailty Scale (CFS) is a validated tool for assessing frailty, and higher scores indicate worse clinical outcomes following cardiovascular procedures. This retrospective study aimed to examine preoperative frailty in relation to recurrence and mortality following curative resection of colorectal cancer. METHODS: We retrospectively analyzed data for 729 consecutive patients undergoing curative resection of stage I-stage III colon and rectal adenocarcinoma between January 2009 and December 2016. Frailty was assessed using the CFS: 1 (very fit) to 9 (terminally ill), and frailty was defined as CFS ≥ 4. Recurrence-free survival (RFS) and overall survival (OS) were compared between frail and nonfrail patients. Cox proportional hazards model was used to calculate hazard ratios (HRs), controlling for potential confounders. RESULTS: CFS score was negatively correlated with the Barthel index of activities of daily living (Spearman's ρ = -0.83). Of the 729 patients, 253 (35%) were frail. In multivariable analyses adjusting for potential confounders including age and disease stage, frailty was independently associated with shorter RFS (multivariable HR: 1.70, 95% confidence interval: 1.25-2.31, P < .001) and OS (multivariable HR: 2.04, 95% confidence interval: 1.40-2.99, P < .001). There were no significant interactions of frailty with age and disease stage regarding RFS and OS (P interaction > .72). CONCLUSION: Preoperative frailty was independently associated with shorter RFS and OS following resection of nonmetastatic colorectal cancer, regardless of age and disease stage. Further trials are needed to establish treatment strategies for frail patients with colorectal cancer.

RESUMO

INTRODUCTION: Liposarcomas comprise around 10%-16% of soft tissue sarcomas. The two major sites of liposarcoma are the extremities and retroperitoneum. However, retroperitoneal liposarcomas mimicking inguinal hernia are rare. We present a case of retroperitoneal liposarcoma mimicking inguinal hernia, which was diagnosed after laparoscopic surgery and underwent curative resection. PRESENTATION OF CASE: A 46-year-old man was admitted to our hospital with a right inguinal pain and swelling that had been recognized for 3 years. We diagnosed the inguinal swelling as a right inguinal hernia and planned laparoscopic surgery for inguinal hernia repair. A hernia sac, however, was not found and swollen retroperitoneal fatty tissue near the right internal inguinal ring was observed by laparoscopy. We aborted the surgical procedure and performed computed tomography and magnetic resonance imaging, which revealed an extraperitoneal and lipomatous tumor extending through the inguinal canal to the scrotum. Wide local excision of the tumor, along with right orchidectomy, was performed under laparotomy. Histopathological diagnosis showed well-differentiated liposarcoma of the retroperitoneum and confirmed tumor-free margins. No evidence of recurrence or metastasis was seen in the 9 months after curative resection. DISCUSSION AND CONCLUSION: Laparoscopic surgery for inguinal hernia enables to observation of the inguinal region and management of rare cases, such as retroperitoneal liposarcoma.

RESUMO

BACKGROUND/AIM: The number of older patients with colorectal cancer (CRC) is increasing. Stage II CRC is a heterogeneous group of cancers with different prognoses. We aimed to examine older patients in relation to clinical outcome following curative resection in stage II CRC. PATIENTS AND METHODS: We analyzed data for 329 consecutive patients with stage II CRC following curative resection. Recurrence-free survival (RFS) and overall survival (OS) were compared between older patients ≥75 years of age and those <75 years. Cox proportional hazards model was used to compute hazard ratios (HRs) controlling for potential confounders. RESULTS: In the multivariable analyses, patients ≥75 years were independently associated with shorter RFS (multivariable HR=2.56, 95% confidence interval (CI)=1.55-4.31, p<0.001) and OS (multivariable HR=4.36, 95%CI=2.08-9.97, p<0.001) in stage II CRC. CONCLUSION: Older patients were independently associated with shorter RFS and OS following curative resection in stage II CRC.

RESUMO

BACKGROUND: Respiratory morbidity is common after esophagectomy and can be a major cause of surgery-related mortality. Thus, it is important to identify novel predictors that can preoperatively estimate the incidence of postoperative respiratory morbidity. Asymptomatic sputum in the respiratory tract is sometimes observed on preoperative computed tomography (CT). This study aimed to determine the clinical importance of sputum in the respiratory tract as a predictor of postoperative morbidity after esophagectomy for esophageal cancer. PATIENTS AND METHODS: The study included 609 consecutive patients who underwent three-incisional esophagectomy for esophageal cancer between April 2005 and November 2018. RESULTS: Among the patients, 76 (12.5%) had sputum in the respiratory tract on preoperative CT. This finding was significantly associated with older age, more extreme smoking habit, worse performance status, lower forced expiratory volume 1%, and more frequent pulmonary comorbidities. Additionally, the incidence of postoperative pneumonia was higher in these patients than in those without sputum (16 vs 8%, p = 0.028). Sputum in the main bronchus was associated with higher frequencies of morbidity of Clavien-Dindo classification (CDc) ≥ II (p = 0.019), severe morbidity of CDc ≥ IIIb (p = 0.058), pneumonia (p = 0.10), and pulmonary morbidity (p = 0.19) compared with the finding of sputum in the trachea alone. On multivariate analysis, sputum in the respiratory tract was an independent risk factor (hazard ratio, 2.07; 95% confidence interval, 1.019-4.207; p = 0.044) for postoperative pneumonia. CONCLUSIONS: Sputum in the respiratory tract is a novel predictor of postesophagectomy pneumonia. Patients with sputum in the more distal respiratory tract might have high risk of postoperative morbidities.
