RESUMEN
BACKGROUND: Fourth-degree perineal tears associated with vaginal delivery (PTAVD) occur in approximately 0.25 to 6% of vaginal deliveries. A persistent challenge in treating fourth-degree PTAVD is the high incidence of anastomotic leakage, leading to impaired quality of life, marked by incontinence, rectovaginal fistula, and painful sexual intercourse. Thus, effective interventions are necessary. Herein, we report our successful approach in repairing a fourth-degree PTAVD, involving the placement of a transanal decompression tube (TDT) during the early postoperative period. CASE PRESENTATION: Five patients underwent the repair of fourth-degree PTAVD by suturing the mucosal and muscular layers of the rectum, and the vaginal wall in layers. Subsequently, a TDT was placed in the rectum, positioned 10-15 cm from the anal verge. The TDT was allowed to drain spontaneously without suction. Gastrografin enema examination was performed through a TDT, followed by a computed tomographic scan on postoperative days 3-4. After unfavorable complications were ruled out, the TDT was removed and the patients were transitioned to a normal diet. RESULT: All patients showed favorable outcomes with no occurrence of vaginal fistula or incontinence. CONCLUSION: This simple intervention demonstrates potential efficacy in reducing anastomotic leakage following the repair of fourth-degree PTAVD.
RESUMEN
Prognostic stratification is an urgent concern for patients with colorectal cancer (CRC). The desmoplastic reaction (DR) is speculated to mirror the tumor microenvironment. DR types are considered independent prognostic indicators in CRC, but have not been incorporated in previous prognostic nomograms. We aimed to assess the prognostic significance of a novel approach incorporating histopathological indicators reflecting tumor glandular differentiation and microenvironment. We evaluated 329 consecutive patients with CRC who underwent surgical resection at Kansai Medical University. Histological glandular differentiation was scored as 2 (0 point), 3 (1 point), or 4 (2 points). Tumor buddings (TBs) were classified as TB1 (0 point), TB2 (1 point), or TB3 (2 points). pT1 or 2 was considered as 0 point, pT3 or 4 + DR non-immature type as 1 point, and pT3 or 4 + DR immature type as 2 points. Lymph node metastasis was classified as pN0 (0 point), pN1 (1 point), or pN2 (2 points). The preoperative carcinoembryonic antigen levels were categorized as < 5.0 ng/mL (0 point) and â§5.0 (1 point). Considering these factors, the following D&M (tumor differentiation and microenvironment) scoring system was applied: I (0-2 points), II (3-4 points), III (5-6 points), and IV (7-9 points). Kaplan-Meier curves showed significant differences in disease-specific survival and recurrence-free survival among the assigned scores, highlighting their enhanced utility compared with the American Joint Committee on Cancer 8th edition staging system. The D&M scoring system was valuable as the initial prognostic nomogram, including DR.

Tailgut cyst is a rare congenital cyst occurring in the retrorectal space and development of neoplastic lesions in tailgut cyst has been reported. Due to the rarity of the tumor, the histogenesis of neoplastic lesions in tailgut cyst has remained elusive. In the present study, the clinicopathological features of tailgut cyst were analyzed with a particular focus on the development of neoplastic lesions. The clinicopathological features of four patients with tailgut cyst (one female and three males) were retrospectively reviewed. No symptoms were present in two patients. Perineal discomfort, and constipation and urinary retention, were described in the other two patients, respectively. Magnetic resonance imaging showed that the cystic lesions were hypointense on T1- and hyperintense on T2-weigted images in all patients. Histopathological analysis revealed that all lesions were multilocular, and cystic walls were covered by squamous and ciliated epithelia without nuclear atypia. The development of neoplastic lesions was noted in two patients. Dysplastic change composed of piling-up proliferation of glandular cells with mild to moderate nuclear atypia was present in one patient, and invasive adenocarcinoma with a dysplasia component was observed in another patient. Dysplasia of the glandular cells, as seen in two patients in the present series, may be a precursor lesion of invasive adenocarcinoma; therefore, adenocarcinoma arsing in tailgut cyst may show a dysplasia-carcinoma sequence. While the reported incidence of neoplastic lesions in tailgut cysts is ~9% or less, their frequency remains to be accurately determined. Therefore, complete surgical resection is important for the management of patients with tailgut cyst. Additional clinicopathological and molecular studies with large cohorts may be required to clarify the histogenesis of neoplastic lesion in tailgut cyst.
RESUMEN
Appendiceal metastases of breast cancer (BC) are very rare, and there are few reports of resection. Asymptomatic appendiceal enlargement is often suspected to be a primary appendiceal tumor, making it difficult to suspect metastatic tumors, especially metastases from BC. On the other hand, advances in drug therapy, including hormonal therapy for BC, have prolonged survival, and there is a possibility of encountering metastatic cases that have rarely been seen before. We herein present a case in which an enlarged appendix, identified during hormonal therapy for advanced BC, was laparoscopically removed and diagnosed as BC metastasis. A 53-year-old woman had been diagnosed with invasive ductal carcinoma (IDC) based on a breast biopsy, and the appendiceal specimen was diagnosed as invasive lobular carcinoma (ILC). We herein report this unique case and provide a detailed review of 13 previous reports.
RESUMEN
Carbon ion radiotherapy (CIRT) has received attention for the treatment of locally recurrent rectal cancer. When the surrounding primary organs are close to the irradiation site, a spacer is required to ensure safe irradiation. This work describes a novel technique using a bioabsorbable polyglycolic acid spacer placed laparoscopically and presents a technical report with five case studies. The short-term surgical outcomes were as follows: mean operating time 235 min with blood loss of 38 mL. CIRT was planned, and the patients underwent irradiation within 2 months of surgery. No pelvic infections occurred, and all procedures were performed safely. Herein, were present a technical report with reference to a video of the surgical procedure.

BACKGROUND: Adjuvant chemotherapy for stage II colorectal cancer (CRC) is considered appropriate for patients with risk factors for recurrence, rather than for all patients uniformly. However, the risk factors for recurrence remain controversial, and there is limited information, especially for elderly patients. The Geriatric Nutritional Risk Index (GNRI) is widely used as a simple nutritional screening tool in the elderly and is associated with cancer prognosis and recurrence. This study aimed to investigate the risk factors for recurrence in the elderly with stage II CRC, focusing on the GNRI. METHODS: We enrolled 348 elderly patients (≥ 75 years) with stage II CRC who underwent curative resection at the Department of Surgery, Tottori University and our 10 affiliated institutions. The patients were divided into GNRIhigh (≥ 93.465) and GNRIlow (< 93.465) groups. RESULTS: The GNRIlow group showed a significantly worse overall survival (OS), cancer-specific survival (CSS), and relapse-free survival (RFS) (P < 0.001, P < 0.001, and P < 0.001, respectively). In a multivariate analysis, GNRIlow (hazard ratio [HR]: 2.244, P < 0.001), pathologic T4 stage (HR: 1.658, P = 0.014), and moderate to severe lymphatic or venous invasion (HR: 1.460, P = 0.033) were independent factors affecting RFS. By using these three factors to score the risk of recurrence from 0 to 3 points, the prognosis was significantly stratified in terms of OS, CSS, and RFS (P < 0.001, P < 0.001, and P < 0.001, respectively). The recurrence rate for each score was as follows: 0 points, 9.8%; 1 point, 22.0%; 2 points, 37.3%; and 3 points, 61.9%. CONCLUSIONS: GNRIlow, pathologic T4 stage, and moderate to severe lymphatic or venous invasion are high-risk factors for recurrence in the elderly with stage II CRC. The scoring system using these three factors appropriately predicted their recurrence and outcome.

Bladder cancer is divided into two molecular subtypes, luminal and basal, which form papillary and nodular tumors, respectively, and are identifiable by gene expression profiling. Although loss of heterozygosity (LOH) of the long arm of human chromosome 9 (9q) has been observed in the early development of both types of bladder cancer, the functional significance of LOH remains to be clarified. The present study introduced human chromosome 9q into basal bladder cancer cell line, SCaBER, using microcell-mediated chromosome transfer to investigate the effect of LOH of 9q on molecular bladder cancer subtypes. These cells demonstrated decreased proliferation and migration capacity compared with parental and control cells. Conversely, transfer of human chromosome 4 did not change the cell phenotype. Expression level of peroxisome proliferator-activated receptor (PPAR)γ, a marker of luminal type, increased 3.0-4.4 fold in SCaBER cells altered with 9q compared with parental SCaBER cells. Furthermore, the expression levels of tumor suppressor PTEN, which regulates PPARγ, also increased in 9q-altered cells. These results suggested that human chromosome 9q may carry regulatory genes for PPARγ that are involved in the progression of neoplastic transformation of bladder cancer.
RESUMEN
Frequent loss of heterozygosity (LOH) on the short arm of human chromosome 3 (3p) region has been found in pancreatic cancer (PC), which suggests the likely presence of tumor suppressor genes in this region. However, the functional significance of LOH in this region in the development of PC has not been clearly defined. The human telomerase reverse transcriptase gene (hTERT) contributes to unlimited proliferative and tumorigenicity of malignant tumors. We previously demonstrated that hTERT expression was suppressed by the introduction of human chromosome 3 in several cancer cell lines. To examine the functional role of putative TERT suppressor genes on chromosome 3 in PC, we introduced an intact human chromosome 3 into the human PK9 and murine LTPA PC cell lines using microcell-mediated chromosome transfer. PK9 microcell hybrids with an introduced human chromosome 3 showed significant morphological changes and rapid growth arrest. Intriguingly, microcell hybrid clones of LTPA cells with an introduced human chromosome 3 (LTPA#3) showed suppression of mTert transcription, cell proliferation, and invasion compared with LTPA#4 cells containing human chromosome 4 and parental LTPA cells. Additionally, the promoter activity of mTert was downregulated in LTPA#3. Furthermore, we confirmed that TERT regulatory gene(s) are present in the 3p21.3 region by transfer of truncated chromosomes at arbitrary regions. These results provide important information on the functional significance of the LOH at 3p for development and progression of PC.

BACKGROUND: As antithrombin III (AT-III) is produced in the hepatocytes, its serum activity decreases at the time of liver failure, in addition to ischemia reperfusion injury, vascular endothelial dysfunction, and disseminated intravascular coagulation (DIC). Here, we examined whether the serum AT-III value after hepatectomy could be a prognostic factor for hepatocellular carcinoma (HCC). METHODS: Of 141 patients who underwent hepatectomy for HCC, data for 101 patients in whom serum AT-III activity was measured on the first postoperative day were extracted. Patients with serum AT-III activity > 50% and ≤ 50% were assigned to high value (72 cases) and low value (29 cases) groups, respectively. We examined the clinical and prognostic differences between these two groups. RESULTS: The average age of enrolled patients (83 men and 18 women) was 68.0 years. The 5-year overall survival rate was 88% and 60% in the high and low value groups, respectively (P < 0.01). Furthermore, the 2-year relapse-free survival rate was 71% and 54% in the high and low value groups, respectively (P = 0.03). CONCLUSION: This is the first study to demonstrate that serum AT-III levels on the first postoperative day may serve as a prognostic factor in HCC patients.
RESUMEN
BACKGROUND: The geriatric nutritional risk index (GNRI), originally developed as a nutritional assessment tool to evaluate mortality and morbidity in older hospitalized patients (i.e., those aged ≥65 years), is regarded as a prognostic factor in several cancers. Body composition is also an important consideration when predicting the prognosis of patients with cancer. This study aimed to investigate the relationship between the GNRI and psoas muscle volume (PMV) for survival outcomes in patients with pancreatic cancer. METHODS: This retrospective study evaluated the prognostic significance of the GNRI and PMV in 105 consecutive patients aged ≥65 years who underwent pancreatectomy for histologically confirmed pancreatic cancer. The patients were divided into high (GNRI > 98) and low GNRI groups (GNRI ≤98), and into high (PMV > 61.5 mm3/m3 for men and 44.1 mm3/m3 for women) and low PMV (PMV ≤ 61.5 mm3/m3 for men and 44.1 mm3/m3 for women) groups. RESULTS: Both the 5-year overall survival (OS) and recurrence-free survival (RFS) rates were significantly greater among patients in the high GNRI group than among patients in the low GNRI group. Similarly, both the 5-year OS and RFS rates were significantly greater among patients in the high PMV group than among patients in the low PMV group. Patients were stratified into three groups: those with both high GNRI and high PMV; those with either high GNRI or high PMV (but not both); and those with both low GNRI and low PMV. Patients with both low GNRI and low PMV had a worse 5-year OS rate, compared with patients in other groups (P < 0.001). The C-index of the combination of the GNRI and PMV for predicting 5-year OS was greater than the C-indices of either the GNRI or PMV alone. Multivariate analysis revealed that the combination of the GNRI and PMV was an independent prognostic factor in patients aged ≥65 years with pancreatic cancer (P = 0.003). CONCLUSIONS: The combination of the GNRI and PMV might be useful to predict prognosis in patients aged ≥65 years with pancreatic cancer.

BACKGROUND: Decreased mean platelet volume (MPV) predicts poor prognosis in some cancers. However, its significance as a prognostic indicator in pancreatic cancer (PC) remains unclear. METHODS: A total of 91 PC patients who underwent pancreatectomy were included in this study. MPV and serum carbohydrate antigen 19-9 (CA19-9) were measured within 1 week before surgery. RESULTS: We divided patients into MPVhigh (≥ 8.65; n = 40), MPVlow (< 8.65; n = 51), CA19-9high (≥ 66.3; n = 47), and CA19-9low (< 66.3; n = 44) groups based on the optimal cut-off values determined from receiver operating characteristic curve analysis. The 5-year overall survival (OS) rates were significantly lower in the MPVlow than in the MPVhigh group (16.9% and 56.3%, respectively; P = 0.0038), and the 5-year disease-specific survival (DSS) rates in the MPVlow group and MPVhigh group were 20.5% and 62.2%, respectively (P = 0.0031). Multivariate analysis identified MPV as an independent prognostic indicator for both OS and DSS. The patients were then divided into groups A (MPVhigh and CA19-9low), B (MPVhigh and CA19-9high), C (MPVlow and CA19-9low), and D (MPVlow and CA19-9high), with 5-year OS rates of 73.2%, 40.4%, 25.8%, and 10.3%, respectively (P = 0.0002), and 5-year DSS rates of 80.8%, 44.9%, 27.3%, and 16.4%, respectively (P = 0.0003). CONCLUSIONS: Classification based on MPV and CA19-9 might be useful for predicting long-term outcomes in patients with PC.

RESUMEN
BACKGROUND: Sarcopenia is a prognostic factor in various cancers. However, the impact of sarcopenia in patients with recurrent pancreatic cancer remains unclear. This study evaluated the prognostic significance of sarcopenia in patients with recurrent pancreatic cancer. METHODS: Seventy-four patients who developed postoperative recurrence of pancreatic cancer after undergoing pancreatectomies were enrolled. Sarcopenia in these patients was defined according to the psoas muscle index (PMI) measured via computed tomography at the third vertebra. RESULTS: The mean PMIs at the time of recurrence were 4.47 ± 1.27 cm2/m2 for men and 3.26 ± 0.70 cm2/m2 for women. Of the 74 patients, 65 (87.8%) were diagnosed with sarcopenia with low PMI. The 2-year post-recurrence survival curve in the sarcopenia group was significantly worse than that in the non-sarcopenia group (P = 0.034). Multivariate analysis revealed that sarcopenia at the time of recurrence was an independent prognostic factor (P = 0.043) along with a high neutrophil-to-lymphocyte ratio (P = 0.004), early recurrence (P = 0.001), and chemotherapy after recurrence (P = 0.005) in patients with recurrent pancreatic cancer. Furthermore, the area under the curve (AUC) of the combination of sarcopenia and time to recurrence for predicting 2-year survival was 0.763, which was much higher than that of sarcopenia alone (AUC = 0.622). CONCLUSIONS: Sarcopenia is a useful prognostic factor in patients with recurrent pancreatic cancer. The combination of sarcopenia and time of recurrence may more accurately predict post-recurrence survival than can sarcopenia alone.

BACKGROUND: The aim of this study was to investigate the usefulness of the range of change in prognostic nutritional index (PNI) during the early postoperative period as a predictor of postoperative pancreatic fistula (POPF) after pancreaticoduodenectomy. METHODS: Data were retrospectively analyzed for 192 patients who underwent pancreaticoduodenectomy. Univariate and multivariate logistic regression analyses were used to evaluate perioperative variables. PNIP3-Pre ratio represented the range of change in PNI from before surgery to postoperative day (POD) 3, PNIP1-Pre ratio represented the range of change in PNI from before surgery to POD 1, and PNIP3-P1 ratio represented the range of change in PNI from POD 1 to POD 3. RESULTS: The area under the curve (AUC) for PNIP3-P1 for prediction of POPF following pancreaticoduodenectomy was 0.683 (P < 0.001), which was highest among PNI ratios and higher than PNI on POD 3. The AUC for serum amylase level on POD 1 was 0.704 (P < 0.001), which was superior to the corresponding AUC on POD 3. The AUC for the combination of PNIP3-P1 ratio and serum amylase level on POD 1 for prediction of POPF was higher than the AUC of either indicator alone (0.743, P < 0.001). The combination of PNIP3-P1 ratio and serum amylase level on POD 1 was an independent predictor of POPF following pancreaticoduodenectomy (P = 0.018). CONCLUSIONS: The combination of the range of change in PNI from POD 1 to POD 3 and serum amylase levels on POD 1 may be useful for prediction of POPF following pancreaticoduodenectomy.

We present a very rare case of a laparoscopically-assisted repair of a small bowel perforation secondary to multiple metastases of undifferentiated pleomorphic sarcoma from the posterior mediastinum. A 46-year-old man presented with middle to upper abdominal pain during chemotherapy for lung metastases from undifferentiated pleomorphic sarcoma. Computed tomography revealed intra-abdominal free air, and emergency laparoscopy was performed. Consequently, a perforation was detected in the jejunum, and partial jejunal resection was performed by mini-laparotomy. Pathological examination demonstrated an ulcerated tumor with perforation and four additional tumors in the resected jejunum. Pathological examination also revealed undifferentiated pleomorphic sarcoma in all five tumors. To our knowledge, our case is the first report of a laparoscopically-assisted repair of a small bowel perforation secondary to metastasis of undifferentiated pleomorphic sarcoma. Although the perforation site was unclear preoperatively, laparoscopic observation readily identified the lesion in this patient. Therefore, minimally invasive surgery could be performed successfully with mini-laparotomy following laparoscopic observation. Laparoscopic techniques for the small intestine are viable options, even in acute and uncommon situations, and small bowel perforation secondary to metastasis should be considered in patients with undifferentiated pleomorphic sarcoma and acute abdomen.
RESUMEN
BACKGROUND/AIM: Indocyanine green (ICG) clearance test is one of the most popular dynamic methods for evaluating preoperative liver function to avoid posthepatectomy liver failure (PHLF). Tc-99m-diethylenetriamine-penta-acetic acid-galactosyl human serum albumin scintigraphy (GSA) also facilitates the direct estimation of functional hepatocytes and can estimate the ICG retention rate (R15); however, in some cases, there is a discrepancy between results of a preoperative examination of ICG-R15 and the estimated ICG-R15 obtained by 99mTc-GSA (GSA-R15). This study evaluated the gap between ICG-R15 and GSA-R15 (ΔICG) for predicting background liver fibrosis in patients who underwent hepatectomy. PATIENTS AND METHODS: Sixty-four consecutive patients who underwent hepatectomy and preoperative ICG-R15 and GSA-R15 examinations from 2016 to 2019 were retrospectively evaluated. The gap between GSA-R15 and ICG-R15 was defined as ΔICG and the factors predicting liver fibrosis were investigated. RESULTS: In the pathologically-proven cirrhotic group, platelet counts were significantly lower and ΔICG values were significantly larger than those in the non-/early-cirrhotic group. A multivariate analysis identified a higher total bilirubin level, a higher AST level, and a larger ΔICG level as significant predictive factors for liver cirrhosis. CONCLUSION: Larger ΔICG was found to be an independent preoperative predictor of liver fibrosis and may positively contribute to decision-making before hepatectomy to avoid PHLF.

BACKGROUND: C-reactive protein (CRP) levels reflect ongoing inflammation and/or tissue damage, and studies suggest that platelets play a role in tumor invasion and metastasis. P-CRP is defined as the multiplied product of serum CRP and platelet levels. Here the prognostic value of pre- and post-operative P-CRP levels in pancreatic cancer (PC) patients was assessed. METHODS: This retrospective study used data from 107 consecutive PC patients who had undergone either pancreaticoduodenectomy or distal pancreatectomy. Clinicopathological parameters and pre/post-operative laboratory data derived from patient records were used for analyses. P-CRP was defined as the product of peripheral thrombocyte count (/uL) × serum CRP level (mg/dL) divided by 104; the optimal P-CRP cut-off value was defined using receiver operating characteristic curves. RESULTS: PC patients were classified as either P-CRPLow (< 1.782; n = 49) or P-CRPHigh (≥ 1.782; n = 58), based on the cut-off value of 1.782. Univariate analysis revealed that performance status, clinical stage, pathological T and N stages, P-CRP, and carbohydrate antigen 19-9 (CA19-9) significantly affected overall survival (OS). Multivariate analysis revealed that independent risk factors for OS were pathological N stage, P-CRP, and CA19-9. Additionally, 103 PC patients for whom postoperative data were available were classified into four groups (P-CRPLow-Down, P-CRPLow-Up, P-CRPHigh-Down and P-CRPHigh-Up), based on preoperative P-CRP and postoperative trend of P-CRP, and we found that prognosis, in terms of OS, was significantly different among these groups (P = 0.012). CONCLUSION: Pre- and post-operative P-CRP values are a potential predictor of prognosis in PC patients.
RESUMEN
BACKGROUND/AIM: Recent studies have investigated a novel inflammation-based prognostic system using the combination of platelet count and neutrophil-lymphocyte ratio (COP-NLR). As platelet count decreases with liver damage, we hypothesized that COP-NLR could indicate both inflammation and hepatic reserve in patients with hepatocellular carcinoma (HCC). This study was conducted to clarify the prognostic significance of preoperative COP-NLR in patients with HCC. PATIENTS AND METHODS: We enrolled 176 patients with histologically-proven HCC who underwent initial curative hepatectomy. Patients were assigned one point each for low platelet count (<15×104/µl) or for high NLR (≥2.0), for hepatic-COP-NLR scores (h-COP-NLR) of 0, 1 or 2. RESULTS: Five-year overall survival (OS) and recurrence-free survival (RFS) rates were 74.5±9%, and 62.2%±9.3% for score 0, 63.6±5.4% and 50.3%±5.6% for score 1, and 45.2±8.8% and 40.6±8.7% for score 2, respectively, and significantly differed (OS: p=0.01; RFS: p=0.03). In multivariate analysis, h-COP-NLR was an independent risk factor for tumor recurrence (HR=1.39, p=0.03) and death (HR=1.71, p=0.02). CONCLUSION: h-COP-NLR was an independent predictor for prognosis of HCC patients after hepatic resection.

BACKGROUND/AIM: To evaluate the impact of DEPDC1 expression on patient prognosis after hepatic resection for hepatocellular carcinoma (HCC). PATIENTS AND METHODS: We reviewed data from 75 patients who underwent hepatic resection for HCC between 2004 and 2013. Recurrence at 2 years following resection, which mainly included metastatic recurrence, was defined as late recurrence. RESULTS: DEPDC1 was up-regulated in HCC tissue and in non-tumor tissue of patients with HCC compared to normal liver (p<0.01 and p<0.01, respectively). High expression of DEPDC1 was associated with poor overall, disease-specific, and disease-free survival (p=0.02, p<0.01, and p<0.01, respectively). High DEPDC1 expression was an independent predictor of death and recurrence (p=0.03 and p<0.01, respectively). High expression of DEPDC1 in non-tumor liver was an independent risk factor for late recurrence (p=0.04). CONCLUSION: High expression of DEPDC1 in tumor tissue appears to be associated with tumor progression and poor prognosis.
