Prognostic Impact of Lymphocyte-C-Reactive Protein Ratio in Patients Who Underwent Surgical Resection for Hepatocellular Carcinoma.

J Gastrointest Surg 2021 Jul 13. Epub 2021 Jul 13.

Department of Surgery, Hiroshima Red Cross Hospital and Atomic-bomb Survivors Hospital, Hiroshima, 730-0052, Japan.

Background: Systemic inflammation-related factors, either independently or in combination, are recognized as prognostic factors for various cancers. The ratio of lymphocyte count to C-reactive protein concentration (lymphocyte-CRP ratio; LCR) is a recently identified prognostic marker for several cancers. Here, we examined the prognostic value of the LCR in patients with hepatocellular carcinoma (HCC).

Methods: This was a single-center retrospective study of patients who underwent surgical resection for HCC between 2004 and 2017. Patients were divided into high- and low-LCR status groups, and the relationships between LCR status, prognosis, and other clinicopathological characteristics were analyzed.

Results: A total of 454 patients with HCC were enrolled and assigned to the high- (n=245) or low- (n=209) LCR groups. Compared with the high-LCR group, patients in the low-LCR group had a significantly lower serum albumin level (median 4.1 vs. 3.9 g/dL, P <0.0001), lower platelet count (median 14.0 vs. 12.0 ×10/μL, P=0.0468), lower prothrombin time (median 93.2 vs. 89.6 %, P=0.0006), and larger tumor size (median 2.3 vs. 2.5 cm, P=0.0056). Patients with low-LCR status had significantly worse outcomes of overall survival and disease-free survival than patients with high-LCR status (P=0.0003 and P=0.0069, respectively). Low-LCR status was significantly associated with worse overall survival in multivariate analysis (hazard ratio 1.57, 95% confidence interval 1.14-2.17, P=0.0058).

Conclusions: Low-LCR status may predict worse outcomes in patients with HCC. Measurement of LCR is routine and can easily be applied for risk stratification in the assessment of patients with HCC.

Hepatic resection for recurrent hepatocellular carcinoma during pregnancy: a case report.

Surg Case Rep 2020 Sep 29;6(1):229. Epub 2020 Sep 29.

Department of Surgery, Hiroshima Red Cross Hospital and Atomic-Bomb Survivors Hospital, 1-9-6 Senda-machi, Naka-ku, Hiroshima, 730-8619, Japan.

Background: Hepatocellular carcinoma (HCC) during pregnancy is extremely rare. Treatment strategies for cancers detected during pregnancy have been controversial. We herein report a case of recurrent HCC detected at 20 weeks of pregnancy, which subsequently prompted hepatic resection after abortion.

Case Presentation: A 36-year-old woman underwent laparoscopic partial hepatectomy for HCC (20 mm in diameter) in segment 5 of the liver during follow-up after being determined as a hepatitis B virus carrier two and a half years ago. Post-surgery follow-up abdominal ultrasonography revealed a 36-mm tumor in segment 7 of the liver. Abdominal contrast-enhanced computed tomography revealed a well-enhanced tumor with a 40-mm diameter in segment 7 adjacent to the inferior vena cava and right hepatic vein, suggesting HCC recurrence. Laboratory data revealed total bilirubin (0.4 mg/dL), aspartate aminotransferase (28 IU/L), alanine aminotransferase (30 IU/L), glutamyltransferase (16 IU/L), prothrombin time (115.3%), and indocyanine green retention rate at 15 min (7.0%). α-Fetoprotein (AFP) (12,371.5 ng/mL; normal range < 10 ng/mL) and PIVKA-II (208 mAU/mL; normal range < 40 mAU/mL) were both significantly elevated. After discussions with a cancer board consisting of experts from the departments of gastroenterology, obstetrics and gynecology, and surgery, as well as obtaining appropriate informed consent from the patient and her family, we decided to perform a hepatic resection after abortion. Subsequently, abortion surgery was performed at 21 weeks and 2 days of pregnancy. After 6 days, subsegmentectomy of liver segment 7 was performed under general and epidural anesthesia, with a pathological diagnosis which was moderately differentiated HCC being established. Given the good postoperative course, without particular complications, the patient was subsequently discharged 10 days after the operation. Approximately 2 years after the surgery, the patient remains alive without recurrence, while both AFP and PIVKA-II were within normal limits.

Conclusions: Treatment strategies for HCC detected during pregnancy remain controversial. As such, decisions should be made based on HCC growth and fetal maturity after thorough multidisciplinary team discussions and obtaining appropriate informed consent from the patient and her family.

Large surgically resected leiomyosarcoma of the liver: a case report.

Surg Case Rep 2020 Jul 9;6(1):168. Epub 2020 Jul 9.

Department of Surgery, Hiroshima Red Cross Hospital and Atomic-bomb Survivors Hospital, 1-9-6 Senda-machi, Naka-ku, Hiroshima 730-8619, Japan.

Background: Primary hepatic leiomyosarcoma (PHL) is an extremely rare type of tumor. We herein report a case of a large surgically resected leiomyosarcoma of the liver.

Case Presentation: A 69-year-old man with a feeling of epigastric compression was referred for examination of an abdominal mass. He had no history of liver disease or alcohol abuse. Liver function tests indicated Child-Pugh class A. Tumor markers were negative. Computed tomography (CT) and magnetic resonance imaging (MRI) revealed a relatively well-contrasted 12 × 11 × 8 cm tumor with well-defined boundary replacing the lateral segment of the liver alongside multiple intrahepatic metastases. Several nodules up to 12 mm were found in both lungs, suggestive of metastasis. SUVmax of the liver mass and lung tumor in positron emission tomography were 10.4 and 1.5, respectively. Hepatocellular carcinoma was primarily suspected. Lateral segmentectomy of the liver was performed to confirm diagnosis and prevent tumor rupture. Macroscopically, the lateral segment of the liver had been replaced by a lobular or multinodular tumor with a maximum diameter of 15 cm. In pathological findings, the tumor consisted of bundle-like proliferation of complicated banding spindle-like cells with clear cytoplasm, accompanied by storiform pattern and compressed blood vessels. Nuclear fission images were observed in 8/10 HPF. Partial necrosis was present, with associated venous invasion and intrahepatic metastasis. Immunohistochemical staining for tumor cells revealed desmin, α-smooth muscle actin (αSMA), and h-caldesmon were all positive, informing a final diagnosis of PHL. The postoperative course was uneventful, and he was discharged on the 12th postoperative day.

Conclusions: PHL is a rare malignant disease with relatively poor prognosis. To confirm a diagnosis of PHL, immunohistochemical analysis as well as histopathological findings is important. The preferred treatment is surgical resection, sometimes in combination with adjuvant chemotherapy and radiotherapy. Further studies are needed to elucidate and better understand this uncommon clinical entity.

Mixed adenoneuroendocrine carcinoma of the distal bile duct: a case report.

Surg Case Rep 2020 Jul 6;6(1):160. Epub 2020 Jul 6.

Department of Surgery, Hiroshima Red Cross Hospital and Atomic-bomb Survivors Hospital, 1-9-6 Senda-machi, Naka-ku, Hiroshima, 730-8619, Japan.

Background: Mixed adenoneuroendocrine carcinoma (MANEC) of the common bile duct (CBD) is very rare, with only 10 reported cases. Here, we report a case of MANEC of the distal bile duct (DBD) that was surgically resected under a diagnosis of cholangiocarcinoma (CCA).

Case Presentation: A 60-year-old male had epigastric pain and was admitted to our hospital for the treatment of a suspected CBD stone. Upon admission, laboratory findings revealed elevated hepatobiliary enzymes including serum aspartate aminotransferase, serum alanine aminotransferase, serum glutamyltransferase, and serum alkaline phosphatase. Both carcinoembryonic antigen and carbohydrate antigen 19-9 were negative. Computed tomography (CT) showed dilation of the CBD. Endoscopic retrograde cholangiopancreatography (ERCP) showed circumferential stenosis and a 5-mm elevated lesion in the DBD. Brush cytology showed atypical ductal cells, indicating adenocarcinoma (AC) of the DBD. Under a diagnosis of CCA of the DBD, a subtotal stomach-preserving pancreaticoduodenectomy was performed. Neither peritoneal dissemination nor lymph node metastasis was found. Microscopically, the lesion was seen to be composed of predominantly well-differentiated tubular AC in the superficial layer of the tumor, admixed with neuroendocrine carcinoma (NEC) in the deeper portion, indicating a diagnosis of MANEC of the DBD. After immunohistochemical staining, NEC components were positive for synaptophysin and CD56 and were for SSTR2, SSTR5, and mammalian target of rapamycin (mTOR). Three months postsurgery, postoperative adjuvant chemotherapy with S-1 was started. More than 3 years postsurgery, he is alive without recurrence.

Conclusions: MANEC is highly malignant, progresses rapidly, and has a poor prognosis. Preoperative diagnosis is difficult; therefore, identifying NEC components by immunohistochemical staining using resected specimens is important.

A case of perforation of Meckel's diverticulum with enterolith.

Surg Case Rep 2020 Jul 6;6(1):161. Epub 2020 Jul 6.

Department of Surgery, Hiroshima Red Cross Hospital and Atomic-bomb Survivors Hospital, 1-9-6 Senda-machi, Naka-ku, Hiroshima, 730-8619, Japan.

Background: Perforation of Meckel's diverticulum with enteroliths is a rare complication. Here, we report a case of perforation of Meckel's diverticulum with one enterolith, which could not be accurately diagnosed by preoperative computed tomography.

Case Presentation: A 16-year-old male patient with acute onset of severe abdominal pain and a localized muscle guarding in the right hypochondrium had a solitary stone detected in the right abdomen by radiography. Abdominal computed tomography revealed a saclike outpouching of the small intestine, which contained fluid levels and an enterolith, with a mesenteric inflammatory change in the right paraumbilical area. He was diagnosed with peritonitis due to appendicitis or Meckel's diverticulitis with enterolith, and emergency operation was indicated. The perforated Meckel's diverticulum was identified approximately 30 cm proximal to the ileocecal valve. The diverticulum was transected at the base and removed. The patient's postoperative course was uneventful.

Conclusions: It is crucial for clinicians to thoroughly examine patients and appropriately request investigations that consider perforation of Meckel's diverticulum as a possible diagnosis to facilitate prompt treatment.

Acute median arcuate ligament syndrome after pancreaticoduodenectomy.

Surg Case Rep 2018 Nov 26;4(1):137. Epub 2018 Nov 26.

Department of Surgery, Hiroshima Red Cross Hospital and Atomic Bomb Survivors Hospital, 1-9-6, Sendamachi, Naka-ku, Hiroshima City, Hiroshima, 730-0052, Japan.

Background: Median arcuate ligament syndrome (MALS) can cause severe complications after pancreaticoduodenectomy (PD). Most of the reported cases of MALS have been diagnosed perioperatively and can be treated efficiently by interventional radiology or division of the median acute ligament (MAL) fibers.

Case Report: A 69-year-old woman underwent PD with resection of the SMV for pancreatic head cancer. Intraoperative exploration showed normal anatomy of the celiac trunk. Intraoperative digital palpation revealed normal pulsation of the common hepatic artery after resection of the gastroduodenal artery. On postoperative day (POD) 3, her liver function tests were abnormal, and bloody fluids were found in the drain. Abdominal CT showed necrosis of the pancreatic body and ischemia in the liver secondary to MALS which was not detected in the preoperative CT. Interventional radiology was tried first but failed. Division of the MAL fibers markedly increased the blood flow in the hepatic artery. Resection of the remnant pancreas and spleen was also performed simultaneously. Abdominal CT on POD 20 showed re-occlusion of the celiac artery. She experienced rupture of the gastrojejunostomy site, severe hepatic cytolysis, and choledochojejunostomy stricture thereafter.

Conclusions: This is the third case of MALS that has developed acutely after PD. MALS can cause refractory complications even after MAL release.

Thymidine Kinase 1 Loss Confers Trifluridine Resistance without Affecting 5-Fluorouracil Metabolism and Cytotoxicity.

Mol Cancer Res 2018 10 4;16(10):1483-1490. Epub 2018 Jun 4.

Department of Surgery and Science, Graduate School of Medical Sciences, Kyushu University, Fukuoka, Japan.

Acquired resistance to therapeutic drugs is a serious problem for patients with cancer receiving systemic treatment. Experimentally, drug resistance is established in cell lines by repeated, continuous exposure to escalating concentrations of the drug; however, the precise mechanism underlying the acquired resistance is not always known. Here, it is demonstrated that the human colorectal cancer cell line DLD1 with acquired resistance to trifluridine (FTD), a key component of the novel, orally administered nucleoside analogue-type chemotherapeutic drug trifluridine/tipiracil, lacks functional thymidine kinase 1 (TK1) expression because of one nonsense mutation in the coding exon. Targeted disruption of the gene also conferred severe FTD resistance, indicating that the loss of TK1 protein expression is the primary cause of FTD resistance. Both FTD-resistant DLD1 cells and DLD1- cells exhibited similar 5-fluorouracil (5-FU) sensitivity to that of the parental DLD1 line. The quantity of cellular pyrimidine nucleotides in these cells and the kinetics of thymidylate synthase ternary complex formation in 5-FU-treated cells is similar to DLD1 cells, indicating that 5-FU metabolism and cytotoxicity were unaffected. The current data provide molecular-based evidence that acquired resistance to FTD does not confer 5-FU resistance, implying that 5-FU-based chemotherapy would be effective even in tumors that become refractory to FTD during trifluridine/tipiracil treatment. .

A case of mixed adenoneuroendocrine carcinoma (MANEC) arising in Barrett's esophagus: literature and review.

Surg Case Rep 2018 May 8;4(1):45. Epub 2018 May 8.

Department of Surgery and Science, Graduate School of Medical Sciences, Kyushu University, 3-1-1 Maidashi, Higashi-ku, Fukuoka, 812-8582, Japan.

Background: Mixed adenoneuroendocrine carcinoma (MANEC) is defined as a neoplasm composed of both exocrine and endocrine carcinomas, each comprising at least 30% of the tumor. MANEC can occur in various organs of the gastrointestinal tract, including the esophagus, stomach, and colon. We herein provide the first case report of surgically resected MANEC arising in Barrett's esophagus (BE).

Case Presentation: A 70-year-old man presenting with abdominal pain was referred to our hospital. Upper endoscopy showed a type 0-IIa + IIc elevated lesion adjacent to BE. According to a biopsy specimen, the elevated lesion was diagnosed as adenocarcinoma with neuroendocrine differentiation. No lymphatic or distant metastasis was detected in the preoperative examination. Laparoscopic distal esophagectomy and proximal gastrectomy were performed, and a diagnosis of MANEC in BE was determined according to the surgically resected specimen.

Conclusions: A very rare case of MANEC in BE was detected. BE can be the origin of esophageal MANEC as well as adenocarcinoma. Due to the small number of esophageal or esophagogastric MANEC cases reported, further accumulation of such cases is necessary to recommend an optimal management strategy for esophageal or esophagogastric MANEC.

Neoadjuvant Chemoradiotherapy for Patients with cT3/Nearly T4 Esophageal Cancer: Is Sarcopenia Correlated with Postoperative Complications and Prognosis?

World J Surg 2018 09;42(9):2894-2901

Department of Surgery and Science, Graduate School of Medical Sciences, Kyushu University, 3-1-1 Maidashi, Higashi-ku, Fukuoka, 812-8582, Japan.

Background: Since the clinical impact of sarcopenia on multimodal therapy for patients with esophageal cancer is not well understood, this study was conducted to determine the influence of sarcopenia on the efficacy of neoadjuvant chemoradiotherapy (NACRT) for locally advanced esophageal cancer.

Methods: The skeletal muscle index was quantified at the level of the third lumbar vertebra on computed tomography images, and sarcopenia was defined as a skeletal muscle index that was less than the average for each gender. We compared treatment outcomes in patients with cT3 and nearly T4 thoracic esophageal squamous cell carcinoma between the sarcopenia group (n = 85) and the non-sarcopenia group (n = 72).

Results: The 5-year survival rates were 33.4% in the non-sarcopenia group and 31.5% in the sarcopenia group; these differences were not significant. The prognosis of the patients with sarcopenia was worse than that of the patients without sarcopenia in the surgery-alone group, but there was no difference between patients with and without sarcopenia in the NACRT group.

Conclusions: NACRT could be a useful option for patients with locally advanced esophageal squamous cell carcinoma, even for those with sarcopenia, without increasing the incidence of morbidity and mortality.

"Energy-less technique" with mini-clips for recurrent laryngeal nerve lymph node dissection in prone thoracoscopic esophagectomy for esophageal cancer.

Am J Surg 2018 12 23;216(6):1212-1214. Epub 2017 Oct 23.

Department of Surgery and Science, Graduate School of Medical Sciences, Kyushu University, Fukuoka, Japan.

Background: Meticulous recurrent laryngeal nerve (RLN) lymph node dissection in thoracoscopic esophagectomy for esophageal cancer often results in RLN paralysis.

Methods: We had attempted to simply cut the vessels around RLN sharply with scissors without using energy device in order to prevent RLN paralysis. However, these procedures often result in minor bleeding. Since we introduced the use of mini-clips for hemostasis before cutting the vessels with scissors, we herein compared the surgical results between before and after the introduction of use of mini-clips.

Results: With regard to RLN paralysis, the incidence was 24.0% in the before group; this incidence went down to 5.1% in the after group (P = 0.0259). Moreover, length of hospital stay after surgery was significantly shortened, from 36.1 days to 22.0 days, after the introduction of energy-less techniques with mini-clips (P = 0.0075).

Conclusions: Our data demonstrated that this technique contributed to prevent RLN paralysis and to shorten the patient's length of hospital stay.

Chemoradiotherapy for Solitary Skeletal Muscle Metastasis from Oesophageal Cancer: Case Report and Brief Literature Review.

Anticancer Res 2017 10;37(10):5687-5691

Department of Surgery and Science, Graduate School of Medical Sciences, Graduate School of Medicine, Kyushu University, Fukuoka, Japan

Background: The incidence of skeletal muscle metastasis from oesophageal cancer is very low, and the treatment strategy has not been established.

Case Report: A 77-year-old man underwent oesophagectomy following neoadjuvant chemotherapy for oesophageal squamous cell carcinoma (CT-pT3 N0 M0, CT-pStage II). Fourteen months after surgery, he became aware of a subcutaneous tumour in his left forearm. Computed tomography and fluorodeoxyglucose positron-emission tomography revealed a 65×75 mm intramuscular nodular lesion with a standardized uptake value of 8.5. Further examination by biopsy strongly suggested this was a solitary metastasis from oesophageal cancer. The patient received chemoradiotherapy with two cycles of 5-fluorouracil combined with cisplatin and radiation. Clinical complete response was confirmed by imaging 7 months after chemoradiation and no recurrence has occurred at 20 months since chemoradiation.

Conclusion: Radiotherapy or chemoradiotherapy can be an alternative locoregional therapy to surgery for solitary skeletal muscle metastasis.

Sarcopenia is an independent predictor of complications after colorectal cancer surgery.

Surg Today 2018 Feb 11;48(2):151-157. Epub 2017 Jul 11.

Department of Surgery and Science, Graduate School of Medical Sciences, Kyushu University, Maidashi 3-1-1, Higashi-ku, Fukuoka, 812-8582, Japan.

Purpose: The significance of sarcopenia after colorectal cancer (CRC) resection has only been discussed with relatively small samples or short follow-up periods. This study aimed to clarify the clinical significance of sarcopenia in a large-sample study.

Methods: We retrospectively analyzed the relationship between sarcopenia and clinical factors, surgical outcomes, and the survival in 494 patients who underwent CRC surgery between 2004 and 2013. Sarcopenia was defined based on the sex-specific skeletal muscle mass index measured by preoperative computed tomography.

Results: Sarcopenia was associated with sex (higher rate of male, P < 0.0001), and low body mass index (P < 0.0001), but not age or tumor stage. Sarcopenia was associated with higher incidence of all postoperative complications (P = 0.02), especially for patients with Clavien-Dindo classification grade ≥2 (CDC; P = 0.0007). Postoperative hospital stays were significantly longer for sarcopenic patients than for non-sarcopenic patients (P = 0.02). In a multivariate analysis, sarcopenia was an independent predictor for postoperative complications (P = 0.01, odds ratio 1.82, 95% confidence interval 1.13-3.00). Among postoperative complications (CDC grade ≥2), sarcopenia was correlated with non-surgical-site infections (P = 0.03). Sarcopenia was not correlated with the overall or recurrence-free survival.

Conclusions: Sarcopenia was an independent predictive factor for postoperative complications after CRC surgery.

Prognostic Significance of Sarcopenia in Patients with Esophagogastric Junction Cancer or Upper Gastric Cancer.

Ann Surg Oncol 2017 Jul 21;24(7):1804-1810. Epub 2017 Feb 21.

Department of Surgery and Science, Graduate School of Medical Sciences, Kyushu University, Fukuoka, Japan.

Background: The association between sarcopenia and postoperative outcomes for patients with gastrointestinal malignancies remains controversial. This study aimed to assess the impact of sarcopenia on short- and long-term outcomes after surgery for esophagogastric junction cancer (EGJC) or upper gastric cancer (UGC).

Methods: The study reviewed 148 patients with EGJC or UGC who underwent surgical resection. The patients were categorized into the sarcopenia group or the non-sarcopenia group according to their skeletal muscle index calculated using abdominal computed tomography images. The study compared clinicopathologic factors, postoperative complications, and prognosis between the two groups.

Results: Sarcopenia was present in 19 patients (32.2%) with EGJC and 23 patients (25.8%) with UGC. The 5-year overall survival (OS) and recurrence-free survival (RFS) rates were significantly poorer in the sarcopenia group than in the non-sarcopenia group (OS 85.5 vs 54.8%, P = 0.0010; RFS 78.7 vs 51.7%, P = 0.0054). The development of postoperative complications did not differ significantly between the two groups. Both the uni- and multivariate analyses showed that N stage (P < 0.0001) and sarcopenia (P = 0.0024 and 0.0293, respectively) were independent poor prognostic factors for OS.

Conclusions: Sarcopenia was strongly associated with a poor long-term prognosis for patients with EGJC or UGC who underwent surgery. The results suggest that special attention might be needed during the development of treatment strategies for patients with sarcopenia who intend to undergo operations for EGJC and UGC.

[The Molecular Aspect of the Antitumor Effect of Oxaliplatin in Combination with 5-FU].

Gan To Kagaku Ryoho 2016 Jun;43(6):707-14

Dept. of Molecular Oncology, Graduate School of Medical Sciences, Kyushu University.

Platinum-based chemotherapeutic drugs as a component of combination chemotherapy are widely used in the treatment of cancer. In particular, oxaliplatin(L-OHP), one such platinum-based chemotherapeutic drug, has a synergistic effect in combination with 5-FU and Leucovorin for the treatment of advanced colorectal cancer. However, the underlying molecular mechanism of this synergistic effect has not been fully clarified yet. In this review, we summarize several updates about the in vitro action of oxaliplatin in human tumor cells and discuss the underlying mechanism of its synergistic effect with 5-FU.
