Abstract
The efficacy of laparoscopic surgery for elderly patients aged over 80 years who have colorectal cancer was investigated concerning complications. Sixty-five patients over 80 years old who underwent colorectal cancer resection until January 2018 were enrolled. Factors that led to complication were analyzed retrospectively. Thirty-three men and 32 women were included, with a median age of 83 years. Forty-eight cases were located at the colon; and 17, at the rectum. The median operating time was 164 minutes, including 39 cases treated with the laparoscopic approach. Postoperative complications were observed in 28 cases(43.1%), of which 15(23.1%)had a Clavien-Dindo(CD)classification of Grade BⅡ. These cases had significantly prolonged postoperative hospital stay. Complications included 10 cases of incisional surgical site infection(SSI), 9 cases of ileus, 6 cases of melena, 2 cases of urinary infection, 2 cases of urinary disorder, and 1 case of postoperative death. Open surgery was the only significant factor associated with the incidence of CD classification of BⅡ(p=0.0330). Among the complications, the incisional SSI was reduced by laparoscopic surgery(p=0.0050). The number of laparoscopic surgeries reduced the incidence of CD classification BⅡ of complications in elderly patients aged over 80 years who had with colorectal cancer resection. The use of incisional SSI also decreased with the use of laparoscopic surgery. Laparoscopic surgery for colorectal cancer in elderly patients may lead to reduced complication rates.

Abstract
We herein report a case of lung metastases from rectal cancer treated with FOLFIRI plus ramucirumab(Ram)therapy after salvage for a long time. A 44-year-old woman underwent low anterior resection for rectal cancer. Fifteen months after the surgery, mFOLFOX6 plus bevacizumab(BV)therapy was initiated for left obturator lymph node metastases. Although the target lesion shrunk, left lung metastasis was found 36 months after the surgery. Partial resection of the lung metastasis was performed, and carbon-ion radiotherapy for pelvic recurrence was administered. Following these treatments, mFOLFOX6 plus BV therapy was administered again for multiple lung metastases 42 months after the surgery. FOLFIRI plus BV therapy, TAS- 102 plus BV therapy, and regorafenib were then administered because of the disease progression. Although the best supportive care was provided after disease progression, FOLFIRI plus Ram therapy was initiated owing to the patient's wish. Although Grade 3 hematological toxicity was observed, severe digestive symptoms were not noted. Long-term administration(approximately 1 year, 21 courses)of the drugs was possible with withdrawal. The patient died due to disease progression 66 months after recurrence. We experienced a case in which FOLFIRI plus Ram therapy after salvage line could be administered for a quite long time. It has been suggested that anti-VEGF drugs with different targets may improve the prognosis even as a late line of therapy if it is tolerable.

Abstract
A 74-year-old man with recurrence of cecal cancer received systemic chemotherapy(CapeOX plus bevacizumab). After the administration of 9 courses, he reported sudden appearance of bloody bowel discharge. Endoscopic examination could not locate the bleeding point. A CT scan indicated that the small intestine was affected by the recurrence of cancer. Therefore, resection of the small intestine was performed after 6 weeks of drug withdrawal. Although direct closure with fascia incision was performed for the repair of wound dehiscence after surgery, re-dehiscence occurred because of paralytic ileus. Wound lavage and nutritional intervention were performed, followed by negative pressure wound therapy. Excellent wound healing was achieved by this therapeutic approach for 3 months.

Abstract
We report a case of effective treatment comprising mFOLFOX6 plus bevacizumab for neuroendocrine carcinoma of the ascending colon. A 60-year-old woman was admitted for diarrhea and abdominal pain. Colonoscopy showed a Type 2 tumor in the ascending colon. She was diagnosed with neuroendocrine cell carcinoma based on biopsy and immunostaining. CT and MRI showed liver metastasis and lymph node #12a metastasis. Right hemi-colectomy, lymphadenectomy, and partial hepatectomy were performed(T4a, N2, M1b, Stage IV). Neuroendocrine cell carcinoma(small-cell type)was finally diagnosed based on a histological examination because the nuclear fission image was 30(/10HPF)and the Ki-67 index was 42%. Three months after the surgery, multiple lymph node metastases were found using CT and MRI. mFOLFOX6 plus bevacizumab was initiated. After 4 courses of the chemotherapy, the metastases responded completely. A total of 10 courses of chemotherapy were administered. About 2 years and 6 months after the surgery, no recurrence is allowed.

Abstract
We herein report a Stage IV case ofrectal cancer in a patient who achieved stable disease and was treated monthly with fluorouracil(FU)monotherapy plus bevacizumab(Bmab)against relapse after residual tumor resection and withdrawal because ofref usal to continue chemotherapy, even though a marked response was obtained with standard chemotherapy. A 73-year-old woman visited a former hospital in 2014, and was diagnosed with rectal cancer with liver and lung metastases (diagnosed with Rb, T3, M1b[liver, lung]cStage IV). Chemotherapy(mFOLFOX6 plus Bmab)was initiated with a consideration of conversion. After 5 courses, she moved to our hospital. Since she was not aggressive to chemotherapy from the beginning, an imaging examination was performed after 9 courses. The primary lesion and lung metastases had disappeared, and there was only one liver metastasis. Partial hepatic resection was performed to attempt chemotherapy withdrawal following informed consent. Six months after surgery with no therapy, since relapse in the rectum and lungs was confirmed, laparoscopic rectal amputation was performed to control the primary tumor. Chemotherapy containing FU monotherapy plus Bmab was reinitiated after 15 months of withdrawal because liver and lung metastases increased 5 months after rectal amputation. Two months after resuming chemotherapy, the metastatic lesion decreased in size, and the tumor marker level normalized. The same regimen is continued monthly, and the response has been maintained for 17 months(infusions of 5-FU/LV plus Bmab, 18 courses).

Abstract
INTRODUCTION There are few reports on the outcome of relapsed cases after curative resection for colorectal cancer(CRC) with adjuvant oxaliplatin-based chemotherapy. Thus, we analyzed such cases. PATIENTS AND METHOD In total, 48 patients with CRC who received oxaliplatin-based postoperative adjuvant chemotherapy from 2012 were analyzed. The clinical course was examined in 9 cases ofrecurrence. RESULTS Stages II, III a, and III b(1, 3, and 5 cases, respectively)were judged as recurrence in 9 cases. Metastatic sites were the lungs, local sites, liver, and peritoneum(3, 3, 3, and 1 case[s], respectively). The median time to relapse was 390 days. There were 2 cases ofwild -type RAS and 7 cases ofmutant RAS. Although R0 resection was performed in 1 case, re-relapse was recognized. Another 8 cases involved induced chemotherapy. An oxaliplatin-based regimen was administered as first-line treatment in 4 of8 cases. At present, 5 patients died, and 3 of8 cases could not progress to second-line treatment. The overall survival(OS)after relapse was 475 days, and survival more than 3 years was not observed. CONCLUSION Recurrent cases after Cur A resection for CRC with oxaliplatin-based adjuvant chemotherapy were examined. Although the 3-year RFS and 5-year OS were relatively good, the prognosis after relapse was quite poor.

Abstract
INTRODUCTION we examined the cases in which surgery was performed for the lower intestinal perforation due to peritoneal dissemination in our hospital. SUBJECTS Four cases of lower intestinal perforation of patients with peritoneal dissemination who underwent emergency operation in our hospital were enrolled. RESULTS Two males and 2 females patients with median age of 65.5 year old(63-71)were included. The perforated sites were 3 cases of small intestine and 1 case of ascending colon, and the APACHE II score at the visit was 14.5(10-16)points. The surgical procedure was performed in 3 cases of resection of the perforated site and 3 cases of stoma creation. In 2 out of 4 cases, it became difficult to control bacterial peritonitis and died on the 16th postoperative day. One case could discharge hospital and continued BSC, survived 4 months after surgery. CONCLUSION Although long-term prognosis could not be expected, there were cases in which it was possible to restart the oral intake after surgery or discharge. Surgical treatment might be selected for the lower intestinal perforation due to peritoneal dissemination.

Abstract
PURPOSE We analyzed to clarify an outcome of multiple resections of metastases from colorectal cancer. PATIENTS AND METHOD Total 7 cases who underwent several resections for metastases from colorectal cancer in Saiseikai Kurihashi Hospital after 2010 were enrolled for analysis. RESULT Age of patients at the time of the primary site resection was 67(45-78)year-old, including 4males and 3 females. Patients located at cecum/ascending/sigmoid/rectosigmoid/upper rectum were 1/1/2/2/1 respectively. Metachronous metastases were found in 5 patients. There were 1 patient for Stage I , 2 patients for Stage III a and III b each and all Stage III patients received adjuvant chemotherapy. The resected organs were 9 in lung, 8 in liver, 1 case in lymph node, local site and peritoneum and the median resected sites were 3(2-4)lesions. In 17 months median observation periods after latest resection, 5 cases have not been prolapsed including 3 cases with chemotherapy. Two cases were relapsed with unresectble status. One case died for 24 months and one case is under the chemotherapy for 12 months. Five year survival rate was 75% and 2 year prolapse free rate was 66.7%, since the relatively good prognosis was obtained by multiple resections. CONCLUSION The cases that multiple resections with R0 were able to perform for the metastases were analyzed. Although cases which become finally to be unresectable exist, it is suggested that the relatively good prognosis might be obtained by multiple resections for metastases.

Abstract
We report the case of a 78-year-old man with liver metastases from rectal cancer treated with hepatectomy after 14 months of chemotherapy. This was the fourth hepatic recurrence after hepatectomy. Distant metastasis of colorectal cancer can be considered for resection, if it can be an R0 resection; however, there is no consensus regarding the timing and extent of resection. Although a study has shown the efficacy of perioperative chemotherapy for resectable liver metastasis from colorectal cancer, the regimen and duration of chemotherapy has not been established yet. It is important that an adequate treatment should be selected for each case, such as chemotherapy as systemic therapy and surgery as local therapy.

Abstract
The cryopyrin-associated periodic syndrome (CAPS) is an autosomal dominant autoinflammatory disease characterized by fever, skin rash, and joint involvement with acute inflammatory response. The genetic defect involves the NLRP3 gene that encodes cryopyrin and leads to an abnormal production of interleukin-1 (IL-1). Therefore, anti-IL-1 treatment represents an effective therapy. One of the most severe manifestations of the disease is secondary amyloidosis that causes renal failure. We present a patient with CAPS who underwent renal transplantation for renal insufficiency caused by amyloidosis. The function of the transplanted kidney deteriorated because of the late administration of IL-1 receptor antagonist, anakinra. This case may indicate the importance of early initiation of anti-IL-1 treatment in CAPS patients who have undergone kidney transplantation.

Abstract
The present study examines the clinical significance of serum neuron-specific enolase (NSE) in patients with adult T cell-leukemia (ATL). Serum NSE values were measured using a radioimmunoassay in 35 patients (acute type, n = 15; lymphoma type, n = 10; chronic type, n = 10) and in 7 controls carrying T lymphotropic virus type-1 (HTLV-1). Serum NSE values >10 ng/mL were detected in 9 of 15 patients with acute type (60%), 5 of 10 with lymphoma type (50%), and in one of 10 patients with chronic type (10%) ATL, but in none of the HTLV-1 carriers. Contrary to previous findings demonstrating that 20% of patients with non-Hodgkin's lymphoma (NHL) had positive serum NSE, the frequency of a high NSE value in patients with acute and lymphoma type ATL was much higher (60% and 50%, respectively). The serum NSE value positively correlated with serum thymidine kinase activity (TK) and serum soluble interleukin-2 receptor (sIL-2R) levels (P < 0.04 and P < 0.01, respectively). Serum NSE values at the initial diagnosis were adversely related to overall survival time according to the log-rank test (P < 0.02). Pathological examinations demonstrated that both patients with anaplastic large cell lymphoma type ATL had cytoplasmic NSE and CD30 markers on cell membranes. These findings suggest that serum NSE is partially produced by ATL cells and that ATL tumor cells seem preferentially produce NSE compared with other NHL cells. Serum NSE may be a novel marker of disease aggressiveness as well as a prognostic factor for ATL.

Abstract
The significance of cytomegalovirus (CMV) infections developed over the clinical course of adult T-cell leukemia/lymphoma (ATLL) were evaluated in relation to the patient survival rate, ATL activity and immunocompetent cells. ATLL patients with CMV infections on admission exhibited a poor survival rate, while patients with CMV infections at any time after admission survived longer than those not infected with this virus. ATLL patients who exhibited a numbers of CMV infection on admission showed higher ATL activity and had lower numbers of CD8-positive and CD56-positive cells than those who developed CMV infections at any time after admission. Therefore, it appears likely that patients with CMV infections on admission were in an immunosuppressive state due to aggressive ATL activity.

Abstract
The relationship between cytomegalovirus (CMV) antigenemia and the clinical course was examined in 57 patients with adult T-cell leukemia/lymphoma (ATLL). All patients included had the acute/lymphoma type of ATL according to the criteria of the Japan Lymphoma Study Group (LSG). CMV antigenemia was assessed on admission and at the time when the patients had fever higher than 37. 5 degrees C, which did not respond to antibiotics for longer than 3 days. The incidence of CMV antigenemia was 44%. Approximately 90% of patients with CMV antigenemia died of infections with viruses, bacteria, and/or fungi, while approximately 40% of patients without CMV antigenemia died of deterioration of ATLL (P<0.0001). In this study, the patients with CMV antigenemia tended to survive longer than those negative for it (321.4 days vs. 266.2 days), although there was no statistical significance (P=0.09). Kaplan-Meier analysis revealed that CMV antigenemia was not a poor prognostic factor. When the disease status of ATLL was evaluated by thymidine kinase (TK) and soluble interleukin 2 receptor (sIL-2R), both had lower titers during CMV antigenemia (TK: P=0.01, sIL-2R: P=0.03, respectively). Therefore, CMV infections in ATLL patients seemed to have bimodal meanings; CMV infection at the end of clinical course were life-threatening, but infection during the first half of clinical course seemed to suppress ATLL activity and to contribute to the longer survival of the patients.

Abstract
A 73-year-old man with acute adult T-cell leukemia (ATL) in remission was re-admitted to our hospital due to drowsiness, headache, and bilateral knee joint pain on May 17, 1998. On admission, examinations revealed decreased serum sodium concentration (112 mEq/l), low plasma osmotic pressure (259 mOsm/l), and elevated antidiuretic hormone(5.6 pg/ml). Cerebrospinal fluid examination showed an increased number of abnormal flower-like lymphocyte (951/microliter). Brain computed tomography and magnetic resonance imaging found no abnormality in the hypothalamus or pituitary gland. These findings yielded a diagnosis of syndrome of inappropriate antidiuretic hormone secretion (SIADH). Though ATL patients typically exhibit a variety of clinical symptoms, SIADH is rarely one of the complications. Further investigation showed that IL-1 beta and IL-6 concentrations were increased in spinal fluid but not in serum. Recently, it has been reported that exogeneous IL-6 is an inducer of ADH secretion, and that primary ATL cells and HTLV-I infected cell lines can produce IL-6. In this case, we speculated that IL-6 produced by ATL cells that infiltrated a cerebral lesion may have played an important role in the development of SIADH.

Abstract
To clarify the properties of an inducible type of nitric oxide synthase (i-NOS) in the brain, we examined whether lipopolysaccharide (LPS) induces NOS in glial cells cultured from neonatal rats. NOS activities (NO2- accumulation and L-[14C]citrulline formation) were detected by treatment with LPS at 10 micrograms/ml for 6-72 hr. L-[14C]citrulline formation by LPS-induced i-NOS was inhibited by NG-monomethyl-L-arginine (a NOS inhibitor) and diphenyleneiodonium (a flavo-protein inhibitor). The activity was not markedly changed in the presence or absence of Ca2+. The induction of i-NOS by LPS was abolished by cycloheximide, actinomycin D, or dexamethasone. In addition, the induction was inhibited by herbimycin A (a tyrosine kinase inhibitor), but was not by staurosporine, W-7, or FK-506. After LPS stimulation, 130 kDa proteins were reacted with anti-rat liver i-NOS antibody 5-72 hr. i-NOS induced from glial cells coupled tightly with endogenous calmodulin (CaM) even in the absence of Ca2+. These results suggest that LPS induces expression of 130-kDa i-NOS through an activation of tyrosine kinase, after which i-NOS couples with CaM, and that NO is formed for 6-72 hr in glial cells.

Abstract
Characterization of the serotonin-induced increase in guanosine 3',5'-cyclic monophosphate (cyclic GMP) was investigated and compared with that induced by atrial natriuretic peptide (ANP) in NG108-15 cells. The cyclic GMP formed by serotonin or ANP was transported in a similar manner to the extracellular medium, although the cyclic GMP formed by bradykinin was not. Serotonin and ANP raised cyclic GMP additively. Serotonin-induced cyclic GMP formation was completely inhibited by pretreatment with 100 nM 12-o-tetradecanoylphorbol 13-acetate (TPA), although that induced by ANP was only partially inhibited and the effects were blocked by pretreatment with staurosporin. In membrane preparations, ANP stimulated cyclic GMP formation in the presence of ATP, but serotonin did not. Serotonin-stimulated cyclic GMP formation was found to occur in neuroblastoma N18TG-2, but not in glioma C6Bu-1. These results suggest that a novel subtype of serotonin receptors (5-HTGC) which stimulates membrane-bound guanylyl cyclase, different from that stimulated by natriuretic peptide, may exist especially in neurons.

Abstract
Nitric oxide (NO) which is produced by activation of Ca2+/calmodulin-dependent NO synthase is known to induce neuronal damage. We examined the effects of 3'-azido-2',3'-dideoxythymidine (AZT, a reverse transcriptase inhibitor), pentamidine (a therapeutic drug for Pneumocystis carinii pneumonia) and calmodulin antagonists such as trifluoperazine and N-(6-aminohexyl)-5-chloro-1-naphthalenesulfonamide (W-7) on NO synthase activation. Although AZT had no effect on the activity of constitutive neuronal NO synthase, pentamidine inhibited the activation of neuronal NO synthase as did trifluoperazine and W-7. The inhibition by pentamidine was prevented by the addition of purified calmodulin. In addition, pentamidine inhibited calmodulin-dependent activation of neuronal NO synthase purified from rat cerebellum. From these results, it is suggested that pentamidine inhibits the neuronal NO synthase activation by probably acting as a calmodulin antagonist.

Abstract
The Escherichia coli mutant NM81, which is deficient in the nhaA gene for the sodium/proton antiporter, still has a sodium ion extrusion activity because of a second antiporter encoded by nhaB (E. Padan, N. Maisler, D. Taglicht, R. Karpel, and S. Schuldiner, J. Biol. Chem. 264:20297-20302, 1989). By chance, we have found that E. coli pop6810 already contains a mutation affecting the sodium ion circulation, probably in or near nhaB, and that its delta nhaA mutant, designated RS1, has no sodium ion extrusion activity at alkaline pH. The growth of RS1 was inhibited completely by 0.1 M sodium, whereas growth inhibition of NM81 was observed only at sodium concentrations greater than 0.2 M. RS1 grew at a normal rate in an alkaline medium containing a low sodium concentration. Furthermore, RS1 grew with a negligible proton motive force in the alkaline medium containing carbonyl cyanide m-chlorophenylhydrazone. The transport activities for proline and serine were not impaired in RS1, suggesting that these transport systems could be driven by the proton motive force at alkaline pH. These findings led us to conclude that the operation of the sodium/proton antiporter is not essential for growth at alkaline pH but that the antiporter is required for maintaining a low internal sodium concentration when the growth medium contains a high concentration of these ions.
