Abstract
A 68-year-old woman with ascending colon cancer was the patient (cT4bN2M1a [LYM] cStage IVA, BRAF V600E mutation-positive, and MSI-high). She was given modified FOLFOXIRI as first-line therapy but did not respond. The infiltration of the primary lesion in the abdominal wall was alleviated, allowing conversion surgery to be performed.

Abstract
Background Chemosensitivity testing, including collagen gel droplet‐embedded culture drug sensitivity test, has proven to be a useful tool in therapeutic decision‐making. This retrospective analysis investigated chemosensitivity testing of peritoneal metastases collected during cytoreductive surgery (CRS), and its impact on survival in patients with colorectal cancer. Methods All patients with peritoneal metastasis from colorectal cancer who underwent CRS with or without hyperthermic intraperitoneal chemotherapy (HIPEC) between November 2008 and October 2014 were included. The growth inhibition rate was expressed as the ratio between the image density after treatment (T) and that before treatment (control, C). Tumours with a reduction in T/C ratio of less than 20 per cent were defined as resistant and those with a reduction of 20 per cent or more as sensitive. Groups were compared for overall (OS) and disease‐free (DFS) survival. Results Of 84 eligible patients, 81 received neoadjuvant chemotherapy (NACT), including 56 patients with an oxaliplatin‐based regimen. Mean(s.d.) follow‐up was 23·4(22·9) months. The median overall survival of all patients was 19·0 (i.q.r. 5·7–36·1) months, with a progression‐free survival time of 10·1 (4·5–17·0) months. Patients who received oxaliplatin‐based NACT had significantly altered chemosensitivity to oxaliplatin; only 20 of 51 such patients showed chemosensitivity to oxaliplatin compared with 16 of 24 who did not undergo oxaliplatin‐based NACT (P = 0·046). However, patients who showed chemoresistance to oxaliplatin had similar OS to those with chemosensitivity (18·8 versus 18·1 months; P = 0·835). The choice of HIPEC agents in patients who received oxaliplatin‐based NACT did not significantly influence survival (oxaliplatin versus mitomycin C: median OS 20·6 (10·9–24·8) versus 19·0 (10·5–34·6) months, P = 0·811; DFS 6·6 (2·8–25·7) versus 9·3 (4·1–13·9) months, P = 0·191). Conclusion Patients who had oxaliplatin‐based NACT showed a higher rate of chemoresistance to oxaliplatin at the time of CRS and HIPEC. The impact of chemosensitivity testing on OS remains unclear and needs further investigation.

Abstract
Simple Summary Approximately 1% of all patients with colorectal cancer, and 15% of patients with peritoneal metastasized colorectal cancer present with the subtype of signet ring cell, which is associated with inferior oncological outcome and reduced overall survival. The evidence whether patients with signet ring cell subtype are benefiting from cytoreductive surgery and hyperthermic intraperitoneal chemotherapy is limited. The aim of this large bicentric retrospective study including 60 patients with this subtype was to explore the survival and define predictive factors of these patients. Median overall survival was 14.4 months, while small bowel PCI > 2 (HR: 6.5; p = 0.008) was the strongest predictive factor for inferior patient survival. The study concludes, that after thoroughly selection patients for CRS and HIPEC, even patients with signet ring cell subtype of colorectal cancer may benefit from this concept. Abstract Signet ring cell subtype (SRC) of colorectal cancer (CRC) is a rare subtype and occurs in approximately 1% of all patients with CRC. Patients with peritoneal metastasis (PM) of SRC have a poor prognosis, and this subtype is frequently considered as a contra-indication for extensive surgical treatment. This retrospective study from two dedicated peritoneal surface malignancy centers in Japan included all patients treated with CRS ± hyperthermic intraperitoneal chemotherapy (HIPEC) between July 1994 and December 2017 from a prospectively maintained database. Preoperative, operative, and postoperative parameters were recorded, including complication rates and follow-up. Sixty of the 320 patients treated with CRS due to CRC were diagnosed with SRC subtype. The mean age of the patients was 51.4 years, and the mean peritoneal carcinomatosis index (PCI) was 13.1. Complete cytoreduction was achieved in 61.7% of cases. The postoperative morbidity rate was 25% and the mortality rate was 1.7%. The median overall survival (OS) was 14.4 months. Cox regression analysis revealed small bowel PCI > 2 (hazard ratio (HR) 6.5; p = 0.008) as the most important factor for OS. With accurate patient selection (e.g., PCI ≤ 12 or small bowel PCI ≤ 2), even patients with PM of CRC with SRC subtype may benefit from CRS and HIPEC, with median OS from 17.8 to 20.8 months and 5-year OS of 11.6%.

Abstract
INTRODUCTION A new treatment strategy involving cytoreductive surgery (CRS) combined with perioperative intraperitoneal (IP) chemotherapy was proposed in 1999 by the Peritoneal Surface Oncology Group International, and the strategy is now justified as a state-of-the-art treatment to improve the long-term survival of patients with peritoneal metastasis (PM). To achieve cure in the patients with PM, complete removal of macroscopic tumors and eradication of micrometastasis on the peritoneum, left after CRS are essential. Systemic chemotherapy is not indicated for the treatment of PM. In contrast, intraperitoneal (IP) chemotherapy brings about significantly higher locoregional dose intensity in the peritoneal cavity and subperitoneal tissues. In combination with anticancer drugs, hyperthermia enhances cytotoxicity against cancer cells. AREA COVERED This article provides a systematic overview of PM from various cancers including gastric, colorectal, small bowel, appendiceal cancer, and mesothelioma. It also includes all the essential aspects of therapy. EXPERT OPINION CRS plus perioperative intraperitoneal chemotherapy is safe with acceptable morbidity and mortality. It is justified as a standard treatment to improve the long-term survival of patients with PM and is now performed with curative intent for PM from various malignancies.

Abstract
UNLABELLED Peritoneal Surface Oncology Group International(PSOGI)proposed a novel treatment, named comprehensive treatment for peritoneal metastasis(PM)from colorectal cancer(CRC). The present study demonstrated the efficacies of the treatment regarding the peritoneal sectors and organs involved with PM from CRC. MATERIALS AND METHODS Among 365 patients received laparotomy, 278 CRC patients with PM underwent complete cytoreductive surgery(CC-0). RESULTS After CC-0 resection Grade 3, Grade 4, and Grade 5 postoperative complication were found in 20(7.2%), 26(9.3%), and 6(2.2%). Five- and 10-year survival rate(YSR)of CC-0 resection were 24.5%, and 11.6% with median survival time(MST)of 42.0 months. Regarding the peritoneal cancer index(PCI)of small bowel(SB-PCI), all patients of PCI B3 died of the disease. In contrast, 10-YSR of patients with SB-PCI of 0, 1, and 2 were 26.1%, 19.5%, and 6.2%, respectively. Ten-YSR of patients with the number of involved peritoneal sectors C9 ranged from 6.9% to 29.8%. MST of patients with PM in each peritoneal sector(sector 0 to sector 8)ranged from 26.4 months to 49.2 months, and 10-YSR ranged from 4.2%to 17.2%. Ten-YSR of patients with involvement of rectum, stomach, liver capsule, seminal vesicle, ureter, uterus, or ovary ranged from 0% to 16.9%. CONCLUSIONS From the present data, PM should be removed aggressively to achieve complete cytoreduction, when the patients with PCIC26, involved peritoneal sectorsC9 and SB-PCIC2 are supposed to receive complete cytoreduction of PM.

Abstract
BACKGROUND AND OBJECTIVES Treatment failure after complete cytoreduction for appendiceal mucinous carcinoma peritonei (AMCP)has not been fully investigated. The present study was performed to clarify the risk factor for recurrence after complete cytoreduction for AMCP. METHODS A total of 400 patients with AMCP who underwent complete cytoreductive surgery combined with perioperative chemotherapy were investigated. RESULTS Documented recurrence was developed in 135 (33.8%)patients. The 5- and 10-year progression-free survival was 51% and 49%, respectively. By multivariate analysis, histological subtype of peritoneal disease(high-grade AMCP[AMCP-H]and AMCP-H with signet ring cells), serum CA19- 9 level, and PCIB20 were significantly associated with reduced progression-free survival. In contrast, histologic subtype of mucin without epithelial cells(MWEC)showed the lowest risk for recurrence. Eighty-six patients had localized intra-abdominal recurrence, and 42 patients had diffuse peritoneal recurrence. Recurrence was found in the various peritoneal sectors. Eighty-one patients underwent complete cytoreduction for the recurrence, and the overall survival 5-year survival rate after secondary cytoreduction was 49%. CONCLUSIONS Risk factors for recurrence were histologic subtype, PCI cutoff level, and serum CA19-9 levels. Aggressive second attempt of cytoreduction in patients with localized recurrence improved the survival.

Abstract
BACKGROUND AND OBJECTIVES The current standard of treatment for malignant peritoneal mesothelioma(MPM)is cytoreductive surgery(CRS)plus perioperative intraperitoneal or systemic chemotherapy(comprehensive treatment), The present study was performed to clarify the prognostic factors of PMP after comprehensive treatment. METHODS Among 63 patients with MPM, male and female patients were 34 and 29. CRSwas performed in 47 patients and complete cytoreduction(CC-0) was performed in 14(22%)patients. Mean numbers of resected peritoneal sectors and organs were 5.2(1-13), and 2.9(0- 9), respectively. Hyperthermic intraperitoneal chemoperfusion(HIPEC)was performed in 27 patients. Grade 1/2, Grade 3, and Grade 4 complications were experienced in 5, 6, and 3 patients, respectively. One patient died of sepsis, and the mortality rate was 2.3%. Independent prognostic factors for favorable prognosis were performance of HIPEC, peritoneal cancer index (PCI)score C12, no distant metastasis and histologic epithelial type. Relative risk of no HIPEC, PCI score B13, presence of distant metastasis and non epithelial type were 7.69, 22.1, 3.6 and 3.9, respectively. CONCLUSIONS Risk factors for death after comprehensive treatment were no HIPEC, PCI score B13, and non epithelial type. However, only 11(17%)patients showed PCI score C12. Accordingly, PCI score should be reducedC12 before CRSby neoadjuvant chemotherapy.

Abstract
To analyze the role of cytoreductive surgery(CRS)plus perioperative chemotherapy on the survival of colorectal cancer(CRC)patients with metachronous peritoneal metastasis(PM). A comprehensive treatment consisting of neoadjuvant chemotherapy plus CRS was performed in 291 CRC patients. Among the 291, 142 and 149 patients had synchronous and metachronous PM, respectively. The results showed no survival difference between the 2 groups. Median survival time(MST)of patients with metachronous PM with complete cytoreduction(CCR-0), small bowel(SB)-PCIC2, PCIC14 and differentiated histologic type ranged from 3.1 to 4.1 years. Five-year survival rates of metachronous group of the CCR-0, SB-PCIC2, PCI C14 and differentiated histologic type ranged from 25.8 to 38.9%. However, the 5-year survival rates of the incomplete cytoreduction(CCR-1), SB-PCIB3, PCIB15 and poorly differentiated type were significantly lower than those of the CCR-0, SB-PCIC2, PCIC14 and differentiated histologic type. Postoperative Grade 3, and Grade 4 morbidity were experienced in 11(5.8%)and 16(10.7%)in metachronous group. Mortalities of metachronous group were 1.3%(2/149). The comprehensive treatment can be performed safely and improves the survival of CRC patients with metachronous PM. After NAC, patients with SB-PCIC2, PCIC14 and differentiated type of histology are candidates for CRS, and CCR-0 resection combined with HIPEC is recommended.

Abstract
The present study reports a case of eosinophilia-associated rectal cancer that was successfully stabilized using chemotherapy, and reviews the mechanisms of eosinophilia and the importance of chemotherapy. A 65-year-old man, who had previously been diagnosed with suspected rectal cancer, presented with the chief complaint of melena. Eosinophilia, abnormal blood coagulation, and elevated carcinoembryonic antigen and carbohydrate antigen 19-9 tumor marker levels were observed, and the patient was subsequently diagnosed with advanced rectal cancer accompanied by multiple lymph node metastases that extended from the para-aortic lymph nodes to the left axillary lymph nodes. The complication of deep vein thrombosis was also observed. Tumor hemorrhage was exacerbated, and thus, Hartmann's procedure was performed. Pathological findings included poorly- to moderately-differentiated adenocarcinoma; however, no eosinophil infiltration was observed within the tumor. Following surgery, the eosinophilia and lymph node metastasis were exacerbated, and an oxaliplatin plus capecitabine chemotherapy regimen was initiated. The patient's eosinophil count and tumor marker levels normalized, and the lymph nodes decreased in size; however, re-enlargement of the lymph nodes was observed 6 months after surgery. The patient was then administered a chemotherapeutic regimen of irinotecan/fluorouracil/folinic acid + bevacizumab, and stable disease was maintained until pleural and peritoneal dissemination were observed at 22 months post-surgery. Following a rapid deterioration in condition, the patient succumbed to the disease at 23 months post-surgery. The present case indicates that although eosinophilia-associated colon cancer exhibits a poor prognosis, early chemotherapeutic intervention may improve this.

Abstract
A nationwide survey has been performed in Japan involving 75 laboratories to assess the relative reliability of different methods of reporting prothrombin time results in anticoagulant control. The interchangeability of results using prothrombin time, prothrombin activity percentage, prothrombin ratio and international normalized ratios (INR) were compared with four different thromboplastin reagents and a range of coagulometers. A secondary batch of reference thromboplastin of human brain origin (BCT/454) was used to calibrate the local thromboplastins and for comparison of methods of reporting. The study revealed the closest agreement of the results between BCT and the other reagents, and the regression lines of these reagents were almost identical, when the results were reported as INR. Box-Whisker plot analysis showed that the distribution of the results was large with the more deficient plasmas with all methods of reporting. It was found by this analysis that the interchangeability of the results was greatest when the results were expressed by INR, because the mean values obtained of each plasma using different thromboplastin reagents gave the lowest CV and the frequency of the far-out data was least, compared with the other methods of expression. On the other hand, the type of coagulometer had almost as much effect as the thromboplastin reagent on the prothrombin time, even if INR was used. Interchangeability of INR would be further improved by providing ISI values for each reagent/instrument combination.

Abstract
Effects of LPS on primary and secondary antibody responses to typical TI-2 antigens were investigated in mice. Simultaneous injection of LPS with a TI-2 antigen showed only little adjuvant effect on the following primary antibody response to the antigen. In contrast, either a single or multiple injections of LPS, prior to the immunization with a TI-2 antigen, significantly augmented the following primary antibody response to the antigen. LPS, however, inhibited the development of B-cell memory to a TI-2 antigen when administered together with the antigen. Moreover, an injection of LPS in mice, which had strong IgM and IgG B-cell memories to a TI-2 antigen, caused disappearance or profound reduction of the memories. The results suggest that LPS produced by gram-negative bacteria exerts inhibitory effects on the development and continuation of B-cell memory to bacterial infections.

Abstract
Peripheral natural killer (NK) cells were identified by their morphologic appearance as large granular lymphocytes (LGLs) in a cytocentrifuged or spun blood film but not in thin wedge blood film. The authors studied the effect of different methods of sample preparation and staining on the enumeration of peripheral human LGLs as a routine test. In the blood film made from anticoagulated venous blood, LGLs were scattered in a field and sometimes deformed by compression of erythrocytes. In a blood film made from mononuclear cells, LGLs were shrunken, rendering it difficult to always identify cytoplasmic granules. In contrast, LGLs were easily and accurately identified in a blood film made from leukocyte-rich plasma, displaying none of the above artifacts. As well, the percentage of LGLs obtained was similar to that obtained from a blood film made from anticoagulated venous blood. In addition, May-Grünwald-Giemsa (MGG) stained azurophilic granules more clearly than did Giemsa above. As a result of these observations, a blood film that was made from leukocyte-rich plasma and that was stained by MGG was considered to be most suitable for the routine enumeration of LGL. Using this method, the authors found a significant correlation between the percentages of LGLs and Leu-7+ cells in the same subjects (r = 0.71; n = 22; P less than 0.001) and also a significant sex difference in the percentages of peripheral LGLs, which were significantly lower in women (17.0 +/- 3.6%; n = 35; P less than 0.05) than in men (19.5 +/- 5.3%; n = 20). Furthermore, the percentage of LGLs with abundant cytoplasmic granules, which might have greater NK activity, was also significantly lower in women (15.9 +/- 3.1%; n = 35; P less than 0.01) than in men (17.9 +/- 4.0%; n = 20).

Abstract
We describe the simple and rapid enzyme immunoassay of protein C in human plasma with use of a Cobas Fara centrifugal analyzer. The antibody, labeled with horseradish peroxidase, is reacted with antigen (protein C) for 15 min. The peroxidase activity of the resulting antigen-antibody conjugate is measured at 500 nm for 5 min in the presence of excess H2O2, phenol, and 4-aminoantipyrine, as compared with that of free conjugates. Results are calculated from a stored standard curve and expressed as a percentage of the value determined for a pooled specimen of normal adult plasma. The standard curve is linear from 0% to 200%. The CV is generally less than 4% for different concentrations of protein C. In liver cirrhosis, hepatocellular carcinoma, therapy with warfarin, thrombosis, and disseminated intravascular coagulation, protein C concentrations are about 40-70% of normal. Results obtained with the present homogeneous enzyme immunoassay correlated well with those by enzyme-labeled immunosorbent assay (r = 0.97).

Abstract
Tolerance induction by oral administration of sheep red blood cells (SRBC) was investigated in young and aged mice. Two-month old C3H/He mice receiving oral administration of 8 X 10(9) SRBC a day for two weeks became tolerant to a subsequent SRBC challenge in the systemic immune system. In contrast, older C3H/He mice aged about 1 year old receiving the same treatment did not become tolerant but resisted tolerance induction and produced a prominent IgG memory in the systemic immune system. Autoimmune-prone NZB mice showed a similar resistance to tolerance induction even at 3 months of age. To investigate a possible role of the liver in the oral tolerance induction, young (2-month old) C3H/He mice received an injection of 1 X 10(8) SRBC via portal vein. The mice thus treated, were not tolerized at all but immunized. The results suggest that gut-associated local immune system play a key role in the induction of the oral tolerance and that the tolerance inducing function of the local immune system declines with aging. Antigens in the gut including denatured self antigens may immunize the systemic immune system of aged animals.

Abstract
Peripheral large granular lymphocytes (LGL) were enumerated in normal subjects and patients with autoimmune thyroid diseases. In normal subjects, the percentage of LGL was significantly lower in women (mean +/- s.d., 17.0 +/- 3.6%; n = 35; P less than 0.05) than in men (19.5 +/- 5.3%; n = 20). In untreated patients with thyrotoxic Graves' disease (GD), both the percentage (11.5 +/- 2.7%; n = 12; P less than 0.001) and the absolute count (244 +/- 102/mm3; P less than 0.01) of LGL were significantly lower than those in normal women (17.0 +/- 3.6% and 334 +/- 122/mm3; n = 35). No significant differences from normal controls were observed in the percentages or absolute counts of LGL in patients with euthyroid GD under treatment or in euthyroid or hypothyroid patients with Hashimoto's disease (HD). The percentage of LGL was inversely correlated with the serum levels of T4 and T3 and the free T4 index, but not with the titre of anti-thyroid antibodies, the size of goitre or the degree of proptosis in the group of untreated patients with GD and HD. The decreased levels of LGL in thyrotoxic patients with GD may be related to the self-perpetuation of thyrotoxicosis in patients with this disease.

Abstract
This report concerns an unusual case of adult T cell leukemia (ATL) complicated with progressive systemic sclerosis (PSS). The surface markers of peripheral blood mononuclear cells (PBM) and lymph node cells, both of which mainly consisted of leukemic cells, were examined. The effect of these cells on the pokeweed mitogen (PWM)-induced IgG synthesis by normal PBM also was studied. The leukemic cells formed rosettes with sheep red blood cells (SRBC; E) and expressed T cell antigen, Leu-1, and DR antigen. The detection of cell surface antigens was carried out by employing monoclonal antibodies against these antigens. We diagnosed this case as DR positive ATL. In terms of the immunoregulatory function of these leukemic cells, the co-culture experiments showed that these cells had some suppressive effect on the PWM-induced IgG production by allogeneic normal PBM.

Abstract
The present study demonstrates that human peripheral blood mononuclear cells (PMC) can be stimulated in vitro to become cytotoxic T lymphocytes (CTL) by PHA. A significant cytotoxic activity of PMC was detected 48 hr after the culture initiation in the presence of 5 micrograms/ml of PHA and the peak level of the activity was obtained by culturing PMC for 72 hr. The cytotoxic cells require the presence of PHA as a cell agglutinin for the expression of their cytotoxic activity. The effector cells mediating the activity were identified as T lymphocytes by E-rosette fractionation of PMC. In this system, removal of carbonyl iron phagocytosed or attached cells from PMC did not abrogate CTL generation of PMC. In addition, human alpha-interferon did not augment CTL generation or expression of their activity. Although the target cells employed were sensitive to natural killer (NK) cells, the effector cells induced by PHA did not seem to have any relation to the NK cells. The present study may provide a useful tool to analyze for precursors of killer T cells.

Abstract
Peripheral T and B lymphocytes were examined in autoimmune thyroid diseases. The percentages of T and B lymphocytes were calculated from the proportions of E and EAC rosette-forming cells and peroxidase-positive cells determined by micromethods. In thyrotoxic Graves' disease, the percentage of T cells was significantly lower, and the percentage of B cells was higher than in normal controls. The absolute count of B lymphocytes was also markedly increased. The serum levels of thyroid hormones showed a significant correlation with the percentage of B cells and an inverse correlation with that of T cells in untreated cases of Graves' disease. Similar abnormalities of lymphocyte subpopulations were observed in patients with thyrotoxic Graves' disease under drug therapy, but the proportions and absolute counts of T and B lymphocytes were normal in euthyroid patients with Graves' disease, either under drug therapy or in remission. No abnormalities in T and B cells were found in Hashimoto's disease. The data indicate that the main feature of the abnormality of the lymphocyte subpopulations in thyrotoxic Graves' disease is an increase of B lymphocytes. The reasons for the discrepancy between our results and those of earlier reports and for the B cell abnormality in Graves' disease are discussed.

Abstract
Thirty cases of ulcerative colitis were examined endoscopically by means of magnifying colonoscope with dye spraying method (the combined method), and their minute mucosal structures were classified into four categories endoscopically, which correlated well with the histological findings. By this procedure, it was easy to detect the subsidence of inflammation of the mucosa in the quiescent phase or to reveal the active inflammatory involvement of the bowel. Moreover, inspecting the minute changes of the colonic mucosa detected by the combined method, remission was more correctly decided and rigid control is contributing to the decrease in the recent rate of recurrence of ulcerative colitis.
