Abstract
Patients experiencing severe side effects when taking high-risk drugs may have a significantly reduced health-related quality of life (QOL); therefore, it is important to identify changes in the health-related QOL in these patients. This study aimed to determine the health-related QOL in community pharmacy outpatients taking high-risk drugs. This prospective observational study was conducted in 29 community pharmacies with 71 pharmacists in 12 regions and cities in Japan from October to December 2020 and 760 patients were enrolled. Using descriptive questionnaires of EuroQOL-5-dimensions-5-levels (EQ-5D-5L), community pharmacists obtained health-related QOL data from outpatients taking high-risk drugs. The mean health-related QOL of all outpatients was 0.869. The health-related QOL decreased with increasing age. The outpatient health-related QOL was 0.700, 0.763, 0.785, and 0.817 when taking antiepileptic, antidepressant, digitalis, and antiarrhythmic drugs, respectively, which was lower than the average health-related QOL of all outpatients. Mobility and pain/ discomfort accounted for a large proportion of the decline in the health-related QOL with increasing age. There were no significant differences in personal care with increasing age; however, the number of outpatients with mobility, normal activity, and pain challenges decreased with age. In contrast, outpatients aged <65 years with anxiety/depression showed a lower than overall average health-related QOL. To the best of our knowledge, this is the first study in Japan to report an investigation by community pharmacists regarding health-related QOL assessment in outpatients taking high-risk drugs.

Abstract
The use of cisplatin may cause nephrotoxicity in patients. Hydration solutions supplemented with magnesium could reduce cisplatin-induced nephrotoxicity. In this study, we evaluated the preventive effect of magnesium pre-loading on cisplatin-induced nephrotoxicity in patients with esophageal cancer. We retrospectively evaluated the prevalence of, and risk factors for, nephrotoxicity in 160 patients with esophageal cancer treated with the 5-fluorouracil/cisplatin regimen from 2014 to 2016 with and without magnesium supplementation. Significant differences were observed between the magnesium and non-magnesium groups in terms of frequency of estimated creatinine clearance of grade 2 or higher that was at 4% (n = 3) and 13% (n = 10) (p = 0.027), respectively. The logistic regression analysis revealed that eCcr of grade 2 or higher was significantly associated with the non-magnesium regimen (odds ratio (OR), 4.175; 95% confidence interval (CI) = 1.061-16.430; p = 0.041) and age ≥ 65 years (OR, 13.951; 95% CI = 1.723-112.974; p = 0.014). This study suggests that 20 mEq magnesium pre-loading significantly reduces the prevalence of cisplatin-induced nephrotoxicity. Furthermore, when cisplatin is administered to individuals older than 64 years, a close observation for the onset of cisplatin-induced nephrotoxicity is crucial.

Abstract
Extended shelf life (ESL) processing (i.e., heat treatment at 130°C for 2 s) is usually not used for producing set yogurt because of the fragility of the curd structure. We investigated the effects of homogenization conducted at higher pressure than the conventional conditions (10 MPa for the first stage and 5 MPa for the second stage) on the curd structure of set yogurt, with a focus on the fat globule size. Each yogurt mix was adjusted at the range of fat globule sizes from 0.45 μm to 1.1 μm by a homogenizer and then heated at 95°C for 5 min (conventional heat treatment), 120°C for 2 s, ESL processing, or 140°C for 2 s. The yogurt mixes were fermented by a common yogurt starter, and the curd texture of the obtained yogurts was evaluated. We observed that the curd hardness and curd firmness of the yogurt were each negatively correlated with the fat globule size regardless of the heat-treatment temperature. Compared with the curd obtained with conventional heat treatment, the ESL-processed curd was extremely fragile, but significantly smooth. With ESL processing, a curd hardness >40 g, which is a sufficient strength for commercial transport systems, was obtained by making the fat particle size <0.6 µm, using 2-stage homogenization pressure: 35 MPa for the first stage and 5 MPa for the second stage. A microscopy analysis indicated that the smaller fat globules reinforce the network structure. The yogurt made by ESL processing and that created with 35 + 5 MPa homogenization had significant sensory evaluation scores. Our results indicate that the combination of ESL processing and 35 + 5 MPa homogenization is a novel and useful method for manufacturing set yogurt.

Abstract
Objective: The efficacy of docetaxel, cisplatin, and 5-fluorouracil (DCF) therapy in treating esophageal cancer has been reported. However, febrile neutropenia (FN) is a potentially serious adverse event of DCF therapy with an incidence of 10 to 40%. Pegfilgrastim, a granulocyte colony-stimulating factor (G-CSF), has been shown to have a primary prophylactic role in FN. However, it has been suggested that excessive use of expensive G-CSF should be avoided. Therefore, we performed a cost-utility analysis of primary prophylaxis with pegfilgrastim. Design: Cost-effectiveness analysis using decision tree modelling. Methods: We used a decision tree analysis model based on the report of primary prophylaxis with pegfilgrastim. Based on a previous study, the FN incidence rate was set at 40.0% (95% confidence interval (CI): 11.9-68.1) for the pegfilgrastim group and 43.5% (95%CI: 21.6-65.4) for the no pegfilgrastim group. The FN treatment cost was US$726.63, and the duration of FN was 3.65±1.20 days. The utility value of patients who received DCF therapy was 0.643, and the change in utility value at FN onset was -0.15. Expected cost, quality-adjusted life year (QALY), and incremental cost-effectiveness ratio (ICER) were calculated, and cost-utility analysis was performed. Results: The ICER of pegfilgrastim was 184,976.75 USD/QALY. As a result of sensitivity analysis, the utility of FN had the greatest impact on the cost-effectiveness analysis, followed by the drug cost of pegfilgrastim. Conclusion: Primary prophylaxis of FN with pegfilgrastim might not be cost-effectiveness. In determining whether to administer pegfilgrastim it is necessary to consider patient factors, not just the incidence of FN.

Abstract
In many phenomena of biological systems, not a majority, but a minority of cells act on the entire multicellular system causing drastic changes in the system properties. To understand the mechanisms underlying such phenomena, it is essential to observe the spatiotemporal dynamics of a huge population of cells at sub-cellular resolution, which is difficult with conventional tools such as microscopy and flow cytometry. Here, we describe an imaging system named AMATERAS that enables optical imaging with an over-one-centimeter field-of-view and a-few-micrometer spatial resolution. This trans-scale-scope has a simple configuration, composed of a low-power lens for machine vision and a hundred-megapixel image sensor. We demonstrated its high cell-throughput, capable of simultaneously observing more than one million cells. We applied it to dynamic imaging of calcium ions in HeLa cells and cyclic-adenosine-monophosphate in Dictyostelium discoideum, and successfully detected less than 0.01% of rare cells and observed multicellular events induced by these cells.

Abstract
Neoadjuvant treatment has become standard care for patients with resectable esophageal cancer. However, some patients cannot undergo surgery or curative resection because of disease progression during neoadjuvant treatment. The aim of this study is to identify the pretreatment characteristics of patients in whom neoadjuvant treatment failed. The study enrolled 231 patients who underwent chemotherapy with cisplatin and 5-fluorouracil (CF) as neoadjuvant therapy for T1N1-3 or T2-3 any-N esophageal squamous cell carcinoma (ESCC). Of these patients, 201 (87.0%) underwent curative resection (R0) and 30 (13.0%) could not undergo curative resection; 19 patients (8.2%) underwent incomplete resection (R1 or R2), and 11 patients (4.8%) could not undergo surgery because of disease progression. We compared clinical characteristics and survival between patients who underwent curative resection (curative group) and those who could not undergo curative resection (noncurative group) to determine the factors predicting noncurative treatment. The noncurative group had significantly worse disease-specific survival than the curative group (P < 0.001). All patients in the noncurative group had cT3 tumors. In 141 patients with cT3 tumors, those in the noncurative group were more likely to have higher serum SCC antigen concentration (P = 0.021), location of the main tumor in the upper to the middle third of the esophagus (P = 0.071), intramural metastases (P < 0.001), advanced N category (P = 0.016), and bulky lymph node metastases (P = 0.060). Multivariate logistic regression analysis identified location of the main tumor in the upper to the middle third of the esophagus (P = 0.047), intramural metastases (P = 0.002), and nodal metastases (N1, P = 0.014; N2, P = 0.015, respectively) as independent predictors of treatment failure in patients with cT3 tumors. Neoadjuvant CF therapy alone may not be effective for patients with cT3 tumors accompanied by these risk factors, and the efficacy of alternative strategies, such as triplet chemotherapy or chemoradiotherapy, should be evaluated.

Abstract
BACKGROUND No potential tumour markers have been validated for prognosis in endometrial cancer. However, carcinoembryonic antigen (cea) is one of the most widely used tumour markers in various types of cancer. Although cea expression in endometrial cancer has been investigated, its prognostic value remains controversial, and no studies have investigated serum cea levels in large case series. In the present study, we investigated diagnostic and prognostic applications of serum cea for endometrial cancer. METHODS This prospective study was approved by our Institutional Review Board. Between January 2006 and December 2012, serum cea was measured prospectively in 215 patients with endometrial cancer and was subsequently measured during treatment and at scheduled follow-up examinations in patients with elevated baseline serum cea. RESULTS During the study period, 215 patients (142 stage i, 19 stage ii, 32 stage iii, 22 stage iv) were treated for endometrial cancer. By the time of last follow-up, 52 had relapsed (24.2%), and the median follow-up duration was 45 months (range: 1-95 months). Elevated serum cea was identified in 25 patients (11.6%) and was associated with histologic type (p = 0.04), histologic grade (p = 0.03), and myometrial invasion depth (p = 0.01). Elevated serum cea was not related to clinical stage, lymph node metastasis, distant metastasis, age, menopausal status, or body mass index. Relapse of disease was related to elevated serum cea (p = 0.006). CONCLUSIONS Serum cea is a potential prognostic indicator for endometrial cancer.

Abstract
BACKGROUND Krukenberg tumors mostly occur after 40 years. Metastatic ovarian tumors in young age are very rare. CASE A 18-year-old female presented with colon cancer which was accompanied by Krukenberg tumor. The present case was a very rare case of metastatic ovarian tumor in very young age. The present patient presented with abdominal pain. On examination, colon tumor was detected and bilateral ovary were almost normal with only slight swelling. During the operation for colon tumor, biopsy of bilateral ovary was performed for histopathological evaluation. Although there were no specific findings in bilateral ovary, microscopic examination revealed poorly differentiated adenocarcinoma, diffusely invading the ovarian parenchyma. Diagnosis of colon cancer was made postoperatively and ovarian Krukenberg tumor was confirmed. CONCLUSION In case of suspecting colon cancer even in very young patient with normal ovary, biopsy of ovary should be considered for the diagnosis of Krukenberg tumor.

Abstract
Nongestational choriocarcinoma is very rare and carries a poor prognosis in female patients. In this report, the authors present a case of nongestational choriocarcinoma with brain metastasis in a female. A 58-year-old female with intermittent back pain was referred to a private hospital. On examination, a mediastinal tumor and a pancreatic tumor were detected. Endoscopic ultrasound-guided fine needle aspiration biopsy of the tumor was performed for histological evaluation. Pathological diagnosis was difficult because only a small amount of tissue was collected. Head MRI showed multiple metastatic tumors in the brain. The patient was diagnosed with primary mediastinal choriocarcinoma with brain metastasis. She was treated with one course of an etoposide, methotrexate, dactinomycin, cyclophosphamide, and vincristine regimen, but her general condition gradually deteriorated, and she died on day 41. Nongestational choriocarcinoma is drug resistant, whereas gestational choriocarcinoma has better chemotherapeutic sensitivity.

Abstract
BACKGROUND Anti-N-methyl D-aspartate (anti-NMDA) receptor encephalitis is often accompanied by ovarian teratoma. Early tumor resection is reported to be effective as a treatment. CASE A 21-year-old woman presented with anti-NMDA receptor encephalitis which was accompanied by ovarian teratoma. The present case was a very rare case of an early stage of anti-NMDA receptor encephalitis receiving operative treatment before confirming the presence of anti-NMDA receptor antibody. The diagnosis was established postoperatively by identifying anti-NMDA receptor antibody. CONCLUSION In case of suspecting anti-NMDA receptor encephalitis in a patient with ovarian teratoma, early operative treatment should be considered even before confirming the presence of anti-NMDA receptor antibody.

Abstract
PURPOSE OF INVESTIGATION Primary peritoneal carcinoma (PPC) is histologically similar to ovarian serous carcinoma, but its biochemical features remain obscure. The authors investigated and compared clinical findings, treatments, and outcomes of patients with PPS and those with epithelial ovarian cancer (EOC) patients. MATERIALS AND METHODS The authors retrospectively reviewed data from 14 patients with PPC and 219 patients with EOC treated at the present hospital from January 2005 to December 2012, including demographic data, pathologic findings, treatments, and outcomes. RESULTS Patients with PPC were significantly older (62.6 ± 8.4 years) than those with EOC (56.3 ± 11.3 years) (p = 0.045). There was no significant difference in serum CA-125 levels. The five-year survival rates did not differ significantly between patients with PPC (61.1%) and those with EOC (60.3%; p = 0.78); nor between patients with PPC and those with Stage III serous EOC (43.8%; p = 0.40). CONCLUSIONS Treatment strategies for EOC applied to PPC apparently led to similar survival patterns among the two patient groups. Cytoreductive surgery combined with pre/postoperative platinum-containing chemotherapy may be effective for PPC patients.

Abstract
OBJECTIVES Chemotherapy-induced thrombocytopenia seems to be a relevant problem and the risk or clinical bleeding in patients wim gynecologic malignancy is reported to be higher than other malignancy. In this study, the authors investigated chemotherapy-induced thrombocytopenia recently performed in all patients with gynecologic malignancy. MATERIALS AND METHODS Between January 2009 and December 2011, the authors examined reported chemotherapy-induced thrombocytopenia using the Common Terminology Criteria for Adverse Events (CTCAE) v.4.0. They analyzed the incidence and clinical features of chemotherapy-induced thrombocytopenia in patients with gynecologic malignancy. RESULTS During this period they administered over 1,614 infusions (29 regimens) to 291 patients. Chemotherapy-induced thrombocytopenia occurred in 43 (14.8%) patients over 56 (3.5%) chemotherapy cycles. Bleeding occurred in 13 (4.5%) patients over 14 (0.9%) cycles. Platelet transfusions were administered for eight (2.7%) patients over eight (0.5%) cycles. Median platelet count at platelet transfusions was 17,000 /μl. Chemotherapy-induced thrombocytopenia was associated with more than five previous chemotherapy cycles, previous radiotherapy, disseminated disease, distant metastatic disease, poor performance status, and taxane-including regimens. Clinical bleeding was associated with previous radiotherapy, distant metastatic disease, poor performance status, and taxane-including regimens. CONCLUSIONS Estimating bleeding risk factor such as previous radiotherapy, distant metastatic disease, poor performance status, and taxane-including regimens seem to be important for safe management of chemotherapy-induced thrombocytopenia.

Abstract
PURPOSE OF INVESTIGATION Chemotherapy-related hypersensitivity reaction seems to be problematic in the safe management of chemotherapy. In this study we investigated chemotherapy-related hypersensitivity reaction in patients with gynecologic malignancy. METHODS Between January 2009 and December 2010, we examined hypersensitivity reaction (> or = grade2) using the Common Terminology Criteria for Adverse Events (CTCAE) v.4.0. We analyzed the incidence, clinical features, management, and outcome. RESULTS We administered over 1,057 infusions (24 regimens) to 205 patients. We found a total of four hypersensitivity reactions (> or = grade 2) cases (carboplatin: 2; nedaplatin: 1; docetaxel: 1). Signs and symptoms were varied. In two cases, the same regimen was rechallenged by using anti-allergic drugs. The docetaxel case was successful. The carboplatin case was not successful. CONCLUSION Chemotherapy-related hypersensitivity reaction (> or = grade2) does not occur frequently. In the case of platinum, especially, carboplatin, re-administering after hypersensitivity reaction should be done carefully though platinum is a key drug in patients with gynecologic malignancies.

Abstract
INTRODUCTION Laparoscopic spleen-preserving distal pancreatectomy (LSPDP) with conservation of the splenic artery and vein has recently been performed as a minimally invasive surgery to retain splenic function in the treatment of pancreatic diseases. As the branches of the splenic vessels are very delicate, division of these branches increases the risk of bleeding. MATERIALS AND METHODS To overcome this problem, we have used the electrothermal bipolar vessel sealer (EBVS) to divide branches of the splenic vessels in LSPDP while conserving the splenic vessels themselves. RESULTS The EBVS reliably provided excellent and safe hemostasis, minimizing the risk of serious blood loss. CONCLUSION Use of the EBVS is safe and efficient in LSPDP with conservation of the splenic vessels.

Abstract
14552 Background: Oxaliplatin-based regimen (FOLFOX regimen) for patients with colorectal cancer have improved survival. Neurotoxicity is the most frequent dose-limiting toxicity of oxaliplatin. Various strategies and pharmacologic agents are currently under investigation to prevent or treat oxaliplatin-induced neurotoxicity. One of them is Stop-and-Go strategy based on the observation of reversibility of the neurotoxic symptoms after discontinuation of oxaliplatin. Stop-and-Go concept will prolong the time of oxaliplatin-based therapy as long as antitumor efficacy is still maintained. Methods: Patients with a histologically verified advanced colorectal carcinoma were eligible for the study. From April 2005 to March 2006 at Cancer Institute Hospital, 187 patients whom treated with bimonthly oxaliplatin-based regimen (FOLFOX4) were enrolled. An oxaliplatin specific neurotoxicity scale are distinct from the National Cancer Institute common toxicity criteria classification (CTC-AE vol. 3). This study was performed to carefully assess the onset and duration to recovery of oxaliplatin neurotoxicity and resumption rate of FOLFOX4. Results: Neurotoxicity was observed in 72 patients with Grade 1, 56 patients with Grade 2 and 33 patients with Grade 3. Oxaliplatin-induced cumulative neurotoxicity develops progressively. The median cumulative doses of oxaliplatin were 170 mg/m2 with Gr. 1; 845.8 mg/m2 with Gr. 2; and 850 mg/m2 with Gr. 3. The median time to onset were 16 days with Gr. 1; 174 days with Gr. 2; and 177 days with Gr. 3. The median time to recovery after stopping the therapy and the median time to progression during the discontinuation of oxaliplatin were 56 and 59 days, respectively, in patients allocated to Gr. 2 compared with 106 and 73 days, respectively, in patients allocated to Gr. 3. The recovery time during the discontinuation showed a statistically significant reduction of the values in the Gr. 2 but not in Gr. 3 (p = 0.0024). The resumption rates of oxaliplatin were 73.7% with Gr. 2 and 46.4% with Gr. 3. Conclusions: Our results may focus to manage time course of Stop-and-Go strategy in clinical practice. No significant financial relationships to disclose.

Abstract
We here present a rare case of intravascular lymphoma (IVL) in a Japanese man. 4 months after cholecystectomy due to cholecystitis, a diagnosis of intravascular lymphoma (IVL) was strongly suspected. Lymphoma cells were diffusely observed in the bone marrow parenchyma, but were absent in the vascular spaces. The patient died of respiratory failure and at autopsy a small number of lymphoma cells in the extravascular parenchyma of the adrenal gland and bone marrow were seen. Serial sections of the surgically resected gallbladder retrospectively confirmed the diagnosis of IVL. In addition, congestion and edema were observed in the connective tissue layer. It is possible that edema or ischemia in the gallbladder wall or at other anatomic sites due to the circulation disturbance induced by the intravascular obstruction of lymphoma cells may have caused the initial symptoms. In conclusion, clinicians and pathologists should keep in mind that the gallbladder may be initially involved in IVL.

Abstract
Hepatitis B virus X protein (HBx) has many cellular functions and is a major factor in hepatitis and hepatocellular carcinoma caused by HBV infection. A proteomic approach was used to search for HBx-interacting proteins in order to elucidate the molecular mechanism of hepatocarcinogenesis. HBx was attached to myc and flag tags (MEF tags) and expressed in 293T cells; the protein complex formed within the cells was purified and characterized by mass spectrometry. COP9 signalosome (CSN) subunits 3 and 4 were subsequently identified as HBx-interacting proteins. In addition, CSN subunit 5, Jun activation domain-binding protein 1 (Jab1), was shown to be a novel cellular target of HBx. In vivo and in vitro interactions between HBx and Jab1 were confirmed by standard immunoprecipitation and GST pull-down assays. An analysis of HBx deletion constructs showed that amino acids 30-125 of HBx were responsible for binding to Jab1. Confocal laser microscopy demonstrated that HBx was mainly localized in the cytoplasm, while Jab1 was found mainly in the nucleus and partially in the cytoplasm, and that the two proteins colocalized in the cytoplasm. The cotransfection of HBx and Jab1 resulted in substantial activator protein 1 (AP-1) activation and knockdown of endogenous Jab1 attenuated AP-1 activation caused by HBx. In addition, the coexpression of HBx and Jab1 potentiated phosphorylation of JNK, leading to the subsequent phosphorylation of c-Jun, whereas the level of c-Jun and JNK phosphorylation induced by HBx was decreased in Jab1 knockdown cells. These results suggest that the interaction between HBx and Jab1 enhances HBx-mediated AP-1 activation.

Abstract
By using multiwalled carbon nanotubes as an element of a nanobiprism, we evaluated quantitatively the coherence of electrons emitted from tungsten tips at room temperature and 78 K, and found an enhancement of coherence at 78 K. The increase of the transverse coherence length of the electron beam agreed well with that of the inelastic mean free path of electrons in solids, demonstrating the direct relationship between the coherences of the electron beam and the original electronic states. On the basis of this experimental fact, we comment on the interpretation of recent Hanbury Brown-Twiss type experiments for electrons reported by Kiesel et al. [Nature (London) 418, 392 (2002)]].

Abstract
While papillary serous adenocarcinomas are histocytologically common in primary peritoneal carcinomas, clear cell carcinomas are rare. We report a new regimen for the treatment of recurrent clear cell carcinomas of the peritoneum. A 45-year-old woman was referred to our hospital and underwent optimal debulking surgery. Thirty-two months after the operation, lymph node swelling and elevation of serum CA19-9 were detected and recurrence was diagnosed. Paclitaxel (175 mg/m(2)) in a 3-hour and carboplatin (300 mg/m(2)) in a 1-hour infusion were repeated at three-week intervals. After completion of four courses, abdominal CT and serum CA19-9 were undertaken and results compared. Lymph node swelling was significantly decreased and the serum CA19-9 level was decreased to within a normal range. Paclitaxel and carboplatin combination chemotherapy may be effective in preventing the recurrence of peritoneal carcinomas.

Abstract
BACKGROUND AND STUDY AIMS No studies comparing virtual computed tomography (CT) cholangioscopy of the common bile duct compared with fiberoptic cholangioscopy are available. The aim of our study was to evaluate the feasibility of virtual CT cholangioscopy of the common bile duct. PATIENTS AND METHODS The study population comprised 52 patients (25 women, 27 men; mean age 56.5, range 32 - 81) with biliopancreatic disorders. Endoscopic images were produced by a volume-rendering method and a perspective projection. The ability to detect the endoluminal view and abnormalities of the common bile duct by virtual CT cholangioscopy and fiberoptic cholangioscopy was evaluated. RESULTS Except for two cases (4 %), virtual CT cholangioscopy revealed excellent and moderate endoluminal visualization. There was no significant difference between the techniques (virtual CT cholangioscopy vs. fiberoptic cholangioscopy: excellent, 73 % vs. 85 %, P = 0.149; moderate 23 % vs. 15 % (P = 0.319); poor, 4 % vs. 0 %, P = 0.153). Virtual CT cholangioscopy revealed no significantly different ability to detect stenosis and obstruction of the common bile duct, compared with fiberoptic cholangioscopy. However, the ability of virtual CT cholangioscopy to detect minute papillary tumors (virtual CT cholangioscopy 30 % vs. fiberoptic cholangioscopy 100 %, P = 0.001) and stones smaller than 5 mm (virtual CT cholangioscopy 25 % vs. fiberoptic cholangioscopy 100 %; P = 0.002 was significantly less than that of fiberoptic cholangioscopy. CONCLUSIONS Virtual CT cholangioscopy cannot replace fiberoptic cholangioscopy completely. However, the use of this technique, instead of fiberoptic cholangioscopy, may be feasible for following up patients after biliary intervention.

Abstract
Comparative immunostaining with antibodies against gastric mucin and p53 was performed on 6 cases of minimal deviation adenocarcinoma (MDA) of the uterine cervix. The MDAs consisted of predominant areas of glands lined by extremely well-differentiated tall columnar epithelial cells with little cytological atypia and minor foci of less well-differentiated glandular epithelium with a minor degree of nuclear atypia. Immunostaining for gastric mucin with a monoclonal antibody HIK1083 revealed that all the tumors areas of typical MDA were partly immunoreactive for HIK1083, but the coexisting less well-differentiated glands were essentially negative. Four MDAs focally contained cells with p53 positive nuclei that were located exclusively in the less well-differentiated cells that lacked gastric mucin. In the pelvic lymph nodes in 2 cases, most of the metastatic tumor was less differentiated and a positive reaction for HIK1083 was observed only in small foci of typical MDA. No significant overexpression of p53 was observed in the metastases. Immunohistochemical expression of gastric mucin and p53 may be related to the histological differentiation of MDA, and detection of p53 overexpression may help to identify critical steps in the local progression of MDA.
