RESUMO
In pancreatic ductal adenocarcinoma (PDAC) patients, the importance of peritoneal lavage cytology, which indicates unresectability, remains controversial. This study sought to determine whether positive peritoneal lavage cytology (CY+) precludes pancreatectomy. Furthermore, we propose a novel liquid biopsy using peritoneal lavage fluid to detect viable peritoneal tumor cells (v-PTCs) with TelomeScan F35, a telomerase-specific replication-selective adenovirus engineered to express green fluorescent protein. Resectable cytologically or histologically proven PDAC patients (n = 53) were enrolled. CY was conducted immediately following laparotomy. The resulting fluid was examined by conventional cytology (conv-CY; Papanicolaou staining and MOC-31 immunostaining) and by the novel technique (Telo-CY; using TelomeScan F35). Of them, 5 and 12 were conv-CY+ and Telo-CY+, respectively. All underwent pancreatectomy. The two double-CY+ (conv-CY+ and Telo-CY+) patients showed early peritoneal recurrence (P-rec) postoperatively, despite adjuvant chemotherapy. None of the three conv-CY+ Telo-CY- patients exhibited P-rec. Six of the 10 Telo-CY+ conv-CY- patients (60%) relapsed with P-rec. Of the remaining 38 double-CY- [conv-CY-, Telo-CY-, conv-CY± (Class III)] patients, 3 (8.3%) exhibited P-rec. Although conv-CY+ status predicted poor prognosis and a higher risk of P-rec, Telo-CY was more sensitive for detecting v-PTC. Staging laparoscopy and performing conv-CY and Telo-CY are needed to confirm the indication for pancreatectomy.

BACKGROUND: Advanced hepatobiliary-pancreatic cancer often invades critical blood vessels, including the portal vein (PV) and hepatic artery. Resection with tumor-free resection margins is crucial to achieving a favorable prognosis in these patients. Herein, we present our cases and surgical techniques for PV wedge resection with patch venoplasty using autologous vein grafts during surgery for pancreatic ductal adenocarcinoma (PDAC) and perihilar cholangiocarcinoma (PhCC). CASE PRESENTATION: Case 1: 73-year-old female patient with PDAC; underwent subtotal stomach-preserving pancreatoduodenectomy, with superior mesenteric vein wedge resection and venoplasty with the right gonadal vein. Case 2: 67-year-old male patient with PDAC; underwent distal pancreatectomy and celiac axis resection, with PV wedge resection and venoplasty with the middle colic vein. Case 3: 51-year-old female patient with type IV PhCC; underwent left hepatectomy with caudate lobectomy and bile duct resection, with hilar PV wedge resection and venoplasty with the inferior mesenteric vein (IMV). Case 4: 69-year-old male patient with type IIIA PhCC; underwent right hepatopancreatoduodenectomy, with hilar PV resection and patch venoplasty with the IMV. All patients survived for over 12 months after the surgery, without local recurrence. CONCLUSIONS: PV wedge resection and patch venoplasty is a useful technique for obtaining tumor-free margins in surgeries for hepatobiliary-pancreatic cancer.
RESUMO
INTRODUCTION: The prognostic nutritional index and D-dimer level are two useful measures for gastric cancer prognosis. Since they each comprise different factors, it is possible to employ a more useful combined indicator. This study therefore aimed to establish a prognostic nutritional index-D score-which combines the prognostic nutritional index and D-dimer level-and validate its usefulness as a prognostic marker. METHODS: We collected data from 1,218 patients with gastric cancer who had undergone radical gastrectomy (R0) between January 2004 and December 2015. Patients were divided into three prognostic nutritional index-D score groups based on the following criteria: score 2, low prognostic nutritional index (≤46) and high D-dimer levels (>1.0 µg/ml); score 1, either a low prognostic nutritional index or high D-dimer levels; and score 0, no abnormality. We then defined the PNI-D score as low (score 0 or 1) and high (score 2). RESULTS: The prognostic nutritional index-D score was significantly associated with overall, recurrence-free, and disease-specific survival (all log-rank P<0.0001). The 5-year overall survival rates of the patients with prognostic nutritional index-D scores of low and high were 88.1% and 64.7%, respectively; their 5-year recurrence-free survival rates were 86.7% and 61.3%, respectively; and their 5-year disease-specific survival rates were 99.3% and 76.5%, respectively. Cox multivariate analysis revealed that a high prognostic nutritional index-D score was an independent, statistically significant prognostic factor for poor overall (P=0.01) survival in the patients with gastric cancer. CONCLUSIONS: The prognostic nutritional index-D is an independent prognostic factor for patients with gastric cancer.
RESUMO
BACKGROUND/AIM: The Japanese Gastric Cancer Treatment Guidelines recommend doublet chemotherapy (S-1 plus another chemotherapy) over S-1 alone for patients with pStage III gastric cancer who underwent radical gastrectomy. However, no consensus exists on adjuvant regimens for patients with pStage III gastric cancer. Therefore, we conducted a comparative study to evaluate the tolerability, safety, and survival outcomes of docetaxel plus S-1 (DS) and S-1 plus oxaliplatin (SOX) therapies as adjuvant chemotherapy for patients with pStage III gastric cancer. PATIENTS AND METHODS: We retrospectively collected data from consecutive patients with gastric cancer who underwent gastrectomy and received DS or SOX therapies postoperatively at the Osaka International Cancer Institute between December 2016 and December 2021. We conducted a propensity score matching analysis to balance clinical backgrounds. RESULTS: Eighty patients who met the eligibility criteria were analyzed. After matching, 40 patients were included in the study (20 each in the DS and SOX groups). No significant adverse events were observed. The mean ratios of the delivered dose to the planned dose were 74.1% and 86.6% for S-1 and docetaxel in the DS group, respectively, and 75.8% and 76.9% for S-1 and oxaliplatin in the SOX group, respectively. No significant differences were found in recurrence-free and overall survival between the DS and SOX groups (p=0.688 and p=0.772, respectively). CONCLUSION: DS and SOX therapies as adjuvants were safe and manageable for patients with pStage III gastric cancer who underwent radical gastrectomy. No significant differences were found in prognosis between the two therapies.

INTRODUCTION: Curative esophagectomy is not always possible in patients with locally advanced esophageal cancer. However, few studies have investigated patients who underwent non-curative surgery with intraoperative judgment. This study aimed to investigate patient characteristics and clinical outcomes for patients undergoing non-curative surgery and compare them between non-resectional and non-radical surgery. METHODS: Among 989 consecutive patients with thoracic esophageal squamous cell carcinoma (ESCC) who were preoperatively expected for curative esophagectomy, 66 who were eligible for non-curative surgery were included in this study. RESULTS: Intraoperative diagnosis of T4b accounted for 93% of the reasons for the failure of curative surgery. In those patients, esophageal cancer locally invaded into the aortobronchial constriction (70%), trachea (25%), or pulmonary vein (5%). LN metastasis mainly invaded into the trachea (50%), or bronchus (28%).The overall survival of patients with non-curative surgery was 51.5%, 25.7%, and 10.4% at 6, 12, and 24 months after surgery, respectively. Although there were no differences in preoperative patient characteristics between non-resectional and non-radical surgery, distant metastasis, especially pleural dissemination, was significantly observed in T4b patients due to esophageal cancer with non-radical surgery than those with non-resectional surgery (35% vs. 15%, P=0.002). Even in patients with non-curative surgery, R1 resection and postoperative CRT were identified as independent factors for survival 1 year after surgery (P=0.047, and 0.019). CONCLUSIONS: T4b tumor located in aortobronchial constriction or trachea/bronchus makes it difficult to diagnose whether it is resectable or unresectable. Moreover, surgical procedures and perioperative treatment were deeply associated with the clinical outcomes.
RESUMO
The anastomotic technique after esophagectomy is of great interest in the prevention of anastomotic complications that adversely affect postoperative recovery. This study aimed to compare the clinical outcomes of modified Collard (MC) and circular stapled (CS) anastomoses after esophagectomy. A total of 504 consecutive patients with thoracic esophageal cancer who underwent esophagectomy and cervical esophagogastric CS or MC anastomosis from January 2013 to December 2019 were enrolled. Out of 504 patients, 134 and 370 underwent CS and MC anastomoses. The frequency of anastomotic leakage and stricture was significantly lesser in the MC group than in the CS group (3.0 vs. 10.5%, P = 0.0014 and 11.1 vs. 34.3%, P < 0.001, respectively). CS anastomosis was an independent risk factor for anastomotic stricture (odds ratio, 4.89; P < 0.001). Oral intake was significantly higher in the group without anastomotic stricture than in the group with anastomotic stricture at 2, 3, and 6 months postoperatively (P < 0.001, P = 0.013, and P < 0.001, respectively). The percentage body weight loss (%BWL) was -12.2% in the group with anastomotic stricture and -7.5% in the group without anastomotic stricture at 3 months postoperatively (P = 0.0012). Anastomotic stricture was an independent factor associated with %BWL (odds ratio, 4.86; P = 0.010). Propensity score-matched analysis, which included 88 pairs of patients, confirmed a significantly lower anastomotic stricture rate in the MC group than in the CS group (10.2 vs. 35.2%, P < 0.001). MC anastomosis is better than CS anastomosis for reducing the frequency of anastomotic stricture, which may be useful for maintaining early postoperative nutritional status.

In cases of pancreatic cancer with anatomical variations of the hepatic artery, it is important to evaluate the hemodynamics of each case for surgical indication. We report the case of a 68-year-old man with locally advanced pancreatic cancer and an aberrant right hepatic artery who underwent distal pancreatectomy with celiac axis resection(DP-CAR). He was admitted to our institute due to abdominal discomfort. A CT scan showed pancreatic cancer invading the common hepatic artery. He underwent chemoradiotherapy with a diagnosis of locally advanced pancreatic cancer. After the tumor downstaging, we performed DP-CAR, which included a gastroduodenal artery and a proper hepatic artery resection. Even though delayed gastric emptying was observed after the operation, he was discharged on postoperative day 36.

BACKGROUND: Duke pancreatic mono-clonal antigen type 2 (DUPAN-II) is a famous tumour maker for pancreatic cancer (PC) as well as carbohydrate antigen 19-9 (CA19-9). We evaluated the clinical implications of DUPAN-II levels as a biological indicator for PC during preoperative chemoradiation therapy (CRT). METHODS: This retrospective analysis included data from 221 consecutive patients with resectable and borderline resectable PC at diagnosis who underwent preoperative CRT between 2008 and 2017. We focused on 73 patients with elevated pre-CRT DUPAN-II levels (> 230 U/mL; more than 1.5 times the cut-off value for the normal range). Pre- and post-CRT DUPAN-II levels and the changes in DUPAN-II ratio were measured. RESULTS: Univariate analysis identified normalisation of DUPAN-II levels after CRT as a significant prognostic factor (hazard ratio [HR] = 2.06, confidence interval [CI] = 1.03-4.24, p = 0.042). Total normalisation ratio was 49% (n = 36). Overall survival (OS) in patients with normalised DUPAN-II levels was significantly longer than that in 73 patients with elevated levels (5-year survival, 55% vs. 21%, p = 0.032) and in 60 patients who underwent tumour resection (5-year survival, 59% vs. 26%, p = 0.039). CONCLUSION: Normalisation of DUPAN-II levels during preoperative CRT was a significant prognostic factor and could be an indicator to monitor treatment efficacy and predict patient prognosis.

BACKGROUND: Surgical site infections are common after pancreaticoduodenectomy. Our institution routinely performs intraoperative bile culture with pancreaticoduodenectomy. Herein we examined whether antibiotic selection based on bile culture analysis reduced the surgical site infection risk after pancreaticoduodenectomy. METHODS: A total of 349 patients underwent pancreaticoduodenectomy with intraoperative bile cultures in our institution between 2008 and 2019. Patients were categorized into "group A" (196 patients who underwent pancreaticoduodenectomy between 2008 and 2013) or "group B" (153 patients who underwent pancreaticoduodenectomy between 2018 and 2019). Group A received cefazoline perioperatively and for 2 days postoperatively, whereas group B received piperacillin-tazobactam instead based on the bile culture findings in group A. RESULTS: In group A, 91 (46.4%) intraoperative bile cultures were positive, and surgical site infections occurred in 61 patients (31.1%). A total of 32 patients had both positive bile culture and surgical site infection, of whom 23 (71.9%) exhibited the same microorganisms in the biliary and surgical site infection cultures. Due to the common finding of cefazoline-resistant Enterococcus spp. and Enterobacter spp. in group A, group B received piperacillin-tazobactam. Surgical site infection incidence in group B was 18.3% (n = 28), which was significantly lower than in group A (P = .006). Cefazoline-resistant Enterococcus spp. and Enterobacter spp., respectively, were cultured in 69.8% and 24.3% of patients with preoperative biliary drainage, compared with 32.2% and 9.7% of patients without preoperative biliary drainage. CONCLUSION: The perioperative selection of antibiotics based on bile culture findings at pancreaticoduodenectomy can reduce the incidence of surgical site infection.

BACKGROUND: Preoperative chemoradiation therapy (CRT) or chemotherapy (CT) followed by surgery is currently being administered for advanced esophageal cancer. However, few studies have directly compared CRT and CT for treating locally advanced esophageal carcinoma. This study aimed to assess postoperative recurrence patterns and post-recurrence outcomes in patients with radical esophagectomy after CRT or triplet CT regimen with docetaxel, cisplatin, and 5-fluorouracil (DCF). METHODS: This study included 325 consecutive patients with thoracic esophageal cancer who received preoperative CRT or DCF followed by curative esophagectomy between January 2010 and December 2019. We compared recurrence patterns after surgery and post-recurrence treatments between CRT and DCF. Locoregional recurrence was defined as recurrences at the primary tumor site or regional lymph nodes. Distant recurrence was defined as non-regional lymph node recurrences, systemic metastases, malignant pleural effusions, or peritoneal metastases. RESULTS: Among 325 patients, 74 received preoperative CF + RT and 251 received preoperative DCF. A propensity score-matched cohort of 53 with CRT and 53 with DCF was included. CRT patients had tumors located in the upper esophagus and had more advanced cancer than DCF patients; however, no differences in patient characteristics were observed in the matched cohort. CRT patients had better histopathological responses and control of locoregional recurrence than DCF patients. On the other hand, distant recurrence, especially in the non-regional lymph node, lung, and pleural dissemination, significantly developed more frequently in CRT patients. Furthermore, CRT patients may have received insufficient post-recurrence treatment, owing to fewer treatment options. Therefore, although there was no difference in recurrence rate in the two groups, CRT patients had significantly poorer post-recurrence survival than DCF patients. CONCLUSIONS: Preoperative DCF could reduce distant recurrence after surgery compared to preoperative CRT. The differences in recurrence patterns can be related to the selection of post-recurrence treatment and their prognosis after recurrence.

BACKGROUND: Despite having once been extensively used for cosmetics or pain reduction, the use of single-incision laparoscopic cholecystectomy (SILC) has declined in recent years due to technical difficulties and a reported increase in complications. Since the introduction of SILC in 2009, our hospital has been actively involved with this technique. Our experience suggests that SILC is not a difficult procedure and can be safe and useful, with particularly excellent cosmetic outcomes. This study retrospectively details the outcomes of SILC at our hospital. METHOD: Data on 1469 cases of SILC performed on a waitlist basis at Osaka Police Hospital from May 2009 to December 2020 were collected and retrospectively analysed. RESULTS: The median operative time and blood loss were 96 min and 0 mL, respectively. A total of 46 patients (3.1%) required conversion surgery, including 36 needing additional ports and 10 requiring laparotomy. Intraoperative complications included common bile duct injury in 1 patient (0.07%) and right hepatic artery injury in 1 patient (0.07%), with no other organ injury. Postoperative Clavien-Dindo 3 or higher complications were observed in 18 patients (1.2%). Incisional hernias occurred in 15 patients (1.0%). The median postoperative hospital stay was 3 days. CONCLUSION: This study showed that SILC can be performed safely without any increase in complications, as reported previously. Granted that it is performed safely, SILC may be a useful technique due to its superior cosmetic outcomes or pain reduction.

A 67-year-old man with a history of appendectomy 40 years ago underwent single-incision laparoscopic surgery for total extraperitoneal inguinal hernia repair. Postoperatively, the pararectal incisional scar obtained from the appendectomy was infected; thus, antibiotic therapy and drainage were performed. However, the infection persisted. After 5 postoperative months, the mesh was laparoscopically removed at a sufficient distance from the infected site. No enterocutaneous fistula was observed. After 1 year and 10 months, no recurrence of hernia or infection was observed. Thus, laparoscopic mesh removal is feasible. Infection of a 40-year-old incision rarely results in mesh infection. Therefore, in pararectal incision, the extent of mesh coverage should be considered; if the overlap is large, changing the technique by not covering the incision may be necessary.

PURPOSE: Pancreatic fistula (PF) is a common and challenging complication after pancreatic surgery. The aim of this study was to investigate the efficacy of a new method for preventing PF utilizing self-assembling peptide hydrogel SPG-178 as a preclinical study. METHODS: The degradability of SPG-178 was confirmed by mixing it with protease. A PF rat model was then established to investigate the efficacy of SPG-178 at preventing PF. After transecting the pancreatic duct toward the spleen, SPG-178 was attached to both sides of the pancreatic stump. The levels of amylase and lipase in both the serum and ascites were measured and surgical specimens investigated pathologically. RESULTS: The hardness of SPG-178 did not change when treated with protease over a short period. The ascitic amylase level was significantly lower in rats treated with SPG-178 than rats who were not 3 days after transection of the pancreatic duct toward the spleen. Pathological examination showed fewer inflammatory cells and presence of a structure body on the surface of the pancreatic stump in the SPG-178-treated group. SPG-178 remained on the surface and many cells that covered it formed fibrous tissue or mesothelium. CONCLUSION: Self-assembling peptide hydrogel SPG-178 has potential as a tool for preventing PF.

BACKGROUND: Long-term outcomes of single-incision laparoscopic colectomy (SILC) for colon cancer (CC), as practiced in real-world settings, especially in relation to disease stage, have not been established. We examined, retrospectively, both short- and long-term outcomes of SILC versus those of multiport laparoscopic colectomy (MPLC) performed for CC in a propensity-score-matched cohort. METHODS: The study involved 263 patient pairs matched 1:1 from among 691 patients who, between January 2008 and May 2014, underwent either SILC or MPLC for a primary solitary CC at our hospital. Short-term and long-term operative outcomes were compared between the two groups. RESULTS: Operation time was the only surgical outcome that varied significantly between the two groups (p = 0.0004). Overall 5-year cancer-specific survival (CSS) in the SILC group was 93.7 (95% CI 89.6-96.2)%, and CSS per pathological stage (I, II and III) was 98.5 (90.0-99.8)%, 96.0 (88.2-98.7)%, and 88.3 (79.6-93.6)%, respectively, whereas overall 5-year CSS in the MPLC group was 93.3 (89.4-95.9)%, and CSS per pathological stage was 100%, 95.4 (88.3-98.3)%, and 84.1 (74.1-90.8)% (p = 0.5278, 0.2679, 0.7666, and 0.9073), respectively. Overall 3-year disease-free survival (DFS) in the SILC group was 94.0 (90.2-96.4)%, and 3-year DFS per pathological stage was 98.6 (90.4-99.8)%, 90.1 (81.4-95.0)%, and 79.0 (69.4-86.2)%, respectively, whereas overall 3-year DFS in the MPLC group was 93.2 (89.4-95.7)%, and 3-year DFS per pathological disease stage was 100%, 94.5 (87.4-97.7)% and 75.5 (64.7-83.8)% (p = 0.2829, 0.7401, 0.4335 and 0.8518), respectively. Thus, oncological outcomes did not differ significantly between groups. Incisional hernia occurred in 21 (8.0%) SILC group patients and 17 (6.5%) MPLC group patients, without a significant between-group difference (p = 0.6139). CONCLUSION: Our data indicate that perioperative and oncological outcomes of SILC performed for CC are comparable to those of MPLC performed for CC.

BACKGROUND: We aimed to clarify usefulness of the modified Frailty Index 11 (mFI-11) for assessing risk of postoperative complications (POCs) and effectiveness of perioperative management team (POMT) intervention for improving postoperative status of frail aged patients requiring colorectal cancer (CRC) surgery. METHODS: We compared, retrospectively, surgical outcomes among 151 consecutive CRC surgery patients aged ≥80 years. Patients were grouped by mFI-11 scores and by POMT intervention (vs. no POMT intervention). RESULTS: POCs were more prevalent, postoperative stays were longer, and discharge status was poorer among high-risk (mFI-11 ≥ 3/11) patients without POMT intervention than among low-risk (mFI-11 ≤ 2/11) patients (p = 0.04, p = 0.02, p < 0.01). Multiple POCs occurred less frequently and performance of activities of daily living was better for high-risk patients with (vs. those without) POMT intervention (p = 0.04, p = 0.03). CONCLUSION: POMT intervention appears beneficial for frail aged patients scheduled for CRC surgery.

PURPOSE: This retrospective study was conducted to compare the long-term outcomes of single-incision totally extraperitoneal (S-TEP) inguinal hernia repair and conventional multiport totally extraperitoneal (M-TEP) inguinal hernia repair. METHODS: The study population included 186 consecutive patients (S-TEP, n = 149; M-TEP, n = 37) who underwent elective surgery for inguinal hernia at Osaka Police Hospital between 2011 and 2013. RESULTS: No significant between-group difference was found in patient or hernia characteristics or in perioperative outcomes, with the exception of age (S-TEP group vs. M-TEP group: median 69 [IQR 60-75] years vs. 64 [55-69] years, respectively; P = 0.019). Furthermore, no significant between-group difference was found in follow-up time (5.5 [3.0-5.8] vs. 5.4 [3.1-5.7] years, P = 0.839), recurrence rate (0.6 vs. 2.4%, P = 0.358), chronic pain (1.2 vs. 0%, P = 1.000), feeling the mesh (2.3 vs. 7.1%, P = 0.142), or movement limitation (0.6 vs. 0%, P = 1.000). All chronic symptoms were "mild but not bothersome." A metachronous contralateral inguinal hernia developed in 8.1% of patients. CONCLUSION: The long-term outcomes of S-TEP repair were comparable to those of M-TEP, with rates of recurrence, chronic pain, feeling the mesh, and movement limitation falling within acceptable limits.

Gastrointestinal cancer (GIC) is a common disease and is considered to be the leading cause of cancer-related death worldwide; thus, new diagnostic and therapeutic strategies for GIC are urgently required. Noncoding RNAs (ncRNAs) are functional RNAs that are transcribed from the genome but do not encode proteins. MicroRNAs (miRNAs) are short ncRNAs that are reported to function as both oncogenes and tumor suppressors. Moreover, several miRNA-based drugs are currently proceeding to clinical trials for various diseases, including cancer. In recent years, the stability of circulating miRNAs in blood has been demonstrated. This is of interest because these miRNAs could be potential noninvasive biomarkers of cancer. In this review, we focus on circulating miRNAs associated with GIC and discuss their potential as novel biomarkers.
RESUMO
BACKGROUND/AIM: The rate of lymph node metastasis (LNM) of colorectal carcinoma (CRC) with a submucosal (SM) invasion depth of 1000 µm or more can reach 12.5%, which is the most common reason for additional resection in daily practice. Other studies have reported that the rate of LNM is less than 2%, regardless of the depth of invasion, if the lesions show good histology, lymphovascular infiltration is negative, and tumor budding is limited. The purpose of this study was to investigate new risk factors for LNM in T1b colorectal cancer. PATIENTS AND METHODS: The 239 patients who were diagnosed with pathological T1b CRC after colorectal surgical resection at the Osaka Police Hospital in Japan between January 2008 and December 2018 were retrospectively reviewed in this study. RESULTS: The LNM rate was 11.3% (27/239). The variables identified as being significant factors using multivariate analysis were: i) lymphatic invasion (Ly)-positive [odds ratio (OR)=5.97; 95% confidence interval (CI)=2.27-15.74], ii) female gender (OR=3.49; 95%CI=1.38-8.85), and iii) left-sided colorectal involvement (OR=4.98; 95%CI=1.22-20.39). If none of these risk factors were present with T1b, the LNM rate was 0% (0/28). CONCLUSIONS: Ly-positive, female gender, and left-sided colorectal involvement could be risk factors for LNM in T1b CRC.

With the advancement of endoscopic resection(ER)of colorectal cancer, surgical resection after ER has been increasing. This study evaluated the effects of initial ER on short- and long-term outcomes in T1b colorectal cancer. This retrospective cohort study enrolled patients with pathological T1b colorectal cancer who underwent colorectal surgical resection between 2008 and 2018. A total of 239 eligible patients were divided into 2 groups: patients initially treated using surgical resection with lymph node dissection(LND)(surgery alone, n=142)and patients treated using initial ER and additional surgical resection with LND(surgery after ER, n=97). No significant differences were observed in short-term outcomes(ie, operative time, blood loss, or postoperative complications)or the long-term outcomes(ie, recurrence rate, overall survival rate, or recurrence free survival rate)between groups.

In cases where carcinomatous meningitis leads to hydrocephalus and increases intracranial pressure, patients present with exacerbated pain and several neurological symptoms. It is reported that multidisciplinary therapy, including radiation therapy, drug therapy, and surgery, is performed for patients with carcinomatous meningitis; however, it is rarely successful. Ventriculoperitoneal shunting(V-P shunt)is a surgical intervention that might relieve the pain temporarily and improve the quality of life. VPS should be taken into consideration in line with patients' and their families' intentions since the overall survival is fairly short.
