Abstract
BACKGROUND Automatic staplers are often used to reconstruct the digestive tract during surgeries for gastric cancer. Intragastric free cancer cells adhering to automatic staplers may come in contact with the laparoscopic port area and progress to port site recurrence. This study aimed to investigate the presence/absence of cancer cells adhering to automatic staplers during gastric cancer surgery using cytological examinations. We further determined the positive predictive clinicopathological factors and clinical implications of free cancer cells attached to automatic staplers. METHODS This study included 101 patients who underwent distal gastrectomy for gastric cancer. Automatic staplers used for anastomosis in gastric cancer surgeries were shaken in 150 ml of saline solution to collect the attached cells. Papanicolaou stains were performed. We tested the correlation between cancer-cell positivity and clinicopathological factors to identify risk factors arising from the presence of attached cancer cells to the staplers. RESULTS Based on the cytology, cancer cells were detected in 7 of 101 (6.9%) stapler washing fluid samples. Univariate analysis revealed that circular staplers, type 1 tumors, and positive lymph nodes were significantly associated with higher detection of free cancer cells adhering to staplers. No significant differences in other factors were detected. Of the seven cases with positive cytology, one developed anastomotic recurrence. CONCLUSIONS Exfoliated cancer cells adhered to the automatic staplers used for anastomoses in 6.9% of the staplers used for distal gastrectomies in patients with gastric cancer. Staplers used for gastric cancer surgeries should be handled carefully.

Abstract
BACKGROUND Only one thyroid follicular cell-derived tumor with a purely trabecular growth pattern has previously been described. This report aims to describe the histological, immunohistochemical, and molecular findings of our second case, propose a novel thyroid tumor, and discuss its diagnostic pitfalls. CASE PRESENTATION A 68-year-old female presented with an encapsulated thyroid tumor composed of thin and long trabeculae. No papillary, follicular, solid, or insular patterns are observed. The tumor cells were elongated or fusiform and arranged perpendicular to the trabecular axis. No nuclear findings of papillary thyroid carcinoma and increased basement membrane material were found. Immunohistochemically, the tumor cells were positive for paired-box gene 8, thyroid transcription factor-1, and negative for thyroglobulin, calcitonin, and chromogranin A. Inter- and intra-trabecular accumulation of type IV collagen-positive materials was not demonstrated. None of PAX8/GLIS1 and PAX8/GLIS3 and mutations in BRAF, HRAS, KRAS, NRAS, TERT promoter, CTNNB1, PTEN, and RET were detected. CONCLUSIONS We report our case as a novel disease entity called non-hyalinizing trabecular thyroid adenoma, which has the diagnostic pitfalls of hyalinizing trabecular tumor and medullary thyroid carcinoma.

Abstract
BACKGROUND The histological classifications of invasive lung adenocarcinoma subtypes are considered to predict patient prognosis after surgical treatment. The objectives of this study were to evaluate cytomorphological characteristics and proliferative activities among the histological predominant patterns by performing cytomorphometric and flow cytometric analyses using liquid-based cytology materials. METHODS Cytological samples fixed by liquid-based cytology preservatives from 53 surgically-resected lung adenocarcinoma specimens were obtained between August 2018 and November 2019. The Papanicolaou-stained and paired Ki-67-stained slides were analyzed for calculating nuclear morphology (nuclear area, nuclear perimeter and nuclear circularity) and Ki-67 labeling index using software. The cell proliferation index (CPIx) was calculated and cellular information including cell cycle stage of tumor cells was obtained by flow cytometry. RESULTS The 53 cases included papillary (n = 29), acinar (n = 8), lepidic (n = 5), and solid (n = 4) subtypes, and invasive mucinous adenocarcinoma (n = 7) were also included. In the lepidic pattern, nuclear area (79.6 ± 28.8 μm2 ) and perimeter (34.1 ± 6.1 μm) were relatively larger and longer than those of the other predominant patterns. The Ki-67 labeling index of the solid pattern (27.9 ± 12.5%) was highest compared with those of other predominant patterns. There were statistically significant differences in the lepidic versus solid patterns and the papillary versus solid patterns (p = .013 and p = .039, respectively). The calculated mean CPIx of the lepidic and the acinar patterns were approximately two-fold higher than those of the other predominant patterns. CONCLUSION By revealing the differences of cytomorphological characteristics, these methodologies might be used for diagnosing cytopathological materials using digital cytopathology.

Abstract
INTRODUCTION Molecular targeted therapies have been established for various diseases, including cancers, and there is an increasing need for molecular testing on cytology specimens. The aim of this study was to determine the optimal preservation methods of liquid-based cytology (LBC) materials for molecular testing. METHODS Cytological samples from 35 surgical resected non-small cell lung carcinoma specimens were obtained between June 2016 and June 2021. The samples were fixed in CytoRich™ red Preservative and stored at 4°C. One week later, three tubes were prepared from each specimen sample and divided into the following groups: the SurePath™ group (continued storage at 4°C), Frozen (Fr) group (stored at -80°C after centrifugation), and LBC-Cell Block (LBC-CB) group (generation of paraffin-embedded CB and storage at 4°C). Samples from 5 patients were used for the time course analysis, and we performed evaluations on these samples at 1, 3, 6, 12, 24, and 36 months. The concentrations and purities of extracted DNA and RNA were measured. The double-stranded DNA (dsDNA) and RNA concentrations were also measured by a fluorometer. The DNA and RNA integrities were quantified by the DNA and RNA integrity number. RESULTS Evaluation of samples was performed at baseline and the six timepoints. In the LBC-CB group, DNA and dsDNA concentrations were higher rather than those in the other groups. The RNA concentration of the LBC-CB group was relatively high compared with those of the other groups at the 36-month timepoint. The Fr group maintained higher DNA quality compared with the other groups over 3 years. The LBC-CB group maintained a higher RNA quality than the other groups until 24 months. CONCLUSION LBC-CB preparation is an effective method to maintain DNA/RNA quality and quantity in long-duration preservation for eventual molecular testing. Therefore, LBC-CB may have applications on preanalytical stage for molecular genomic testing such as next-generation sequencing.

Abstract
The Japanese Society of Thyroid Pathology and the Japan Association of Endocrine Surgeons developed the eighth edition of the General Rules for the Description of Thyroid Cancer (GRDTC) in December 2019. This article describes the pathological diagnosis of the GRDTC, which has been improved through repeated revisions based on the experience of Japanese pathologists and translated into English to introduce the Japanese diagnostic standard to foreign countries. In this edition of the GRDTC, the histopathological classification and descriptions differ in some respects from those of the fourth edition of the World Health Organization (WHO) classification as revised in 2017. For example, the GRDTC does not adopt the concept of borderline lesions (FT-UMP, WDT-UMP, and NIFTP) of the WHO, taking into consideration the popular histological criteria accepted by Japanese pathologists. The cytological reporting system of the GRDTC was partly modified from the Bethesda system in 2015. It has an additional cyst fluid category separated from the unsatisfactory category that has been demonstrated to be useful in Japan. This translated edition makes it easy to submit Japanese clinicopathological studies of thyroid tumors in an international journal. We also wish to contribute to the improvement, standardization, and globalization of the pathological diagnosis of thyroid tumors.

Abstract
Immune checkpoint inhibitors such as anti-cytotoxic T-lymphocyte antigen-4 and anti-programmed death-1 antibodies are effective against malignant tumors. However, they induce unique adverse events known as immune-related adverse events. Hypophysitis is one of the most frequent immune-related adverse events of anti-cytotoxic T-lymphocyte antigen-4 therapies. However, there have been few reports describing the pathological findings of hypophysitis induced by anti-programmed death-1 antibodies. The present case is the first autopsy case of hypophysitis induced by nivolumab monotherapy, an anti-programmed death-1 antibody. Pathologically, lymphocytes infiltrated the anterior lobe of the pituitary gland, and the number of pituitary cells, especially adrenocorticotropic hormone-positive cells, decreased. However, necrosis and remarkable fibrosis were not observed. Immunohistologically, some pituitary cells expressed programmed death-ligand 1. Lymphocytes were predominantly CD8-positive T cells, and CD68-positive macrophages and CD20-positive B-cells were also observed. IgG and C4d were deposited on pituitary cells, but IgG4 (a subclass of nivolumab) was not detected. These findings indicate that type IVc and type II hypersensitivity mechanisms may occur in hypophysitis induced by anti-programmed death-1 antibodies and that the inflammatory mechanisms underlying hypophysitis induced by anti-programmed death-1 and anti-cytotoxic T-lymphocyte antigen-4 antibodies are different.

Abstract
Background Adenosquamous carcinoma of the prostate (ASCP) is an extremely rare and aggressive prostate cancer variant, whose genomic characteristics have not been elucidated. Although liquid biopsy of circulating tumor cells (CTCs) is an emerging topic in oncology, no study has assessed CTCs in patients with ASCP. Case presentation. A 76-year-old man presented with discomfort in his urethra. His prostate-specific antigen (PSA) level was 13.37 ng/mL. A computed tomography (CT) scan indicated a prostate mass with multiple lymph node and lung metastases. The patient underwent transurethral resection of the prostate and prostatic needle biopsy; both specimens demonstrated Gleason grade group 5 acinar adenocarcinoma of the prostate. Bone scintigraphy indicated bone metastasis in the ischium. Combined androgen blockade was implemented, and his serum PSA level rapidly decreased to 0.01 ng/mL. However, a CT scan 6 months after the initial diagnosis revealed worsening of the disease. The patient therefore underwent repeated prostatic needle biopsy; its specimen demonstrated prostatic adenocarcinoma together with squamous carcinoma components. As immunohistochemical analyses showed the tumor cells to be negative for CD56, chromogranin A, synaptophysin, and PSA, the definitive diagnosis was ASCP. Although the patient underwent chemotherapy (docetaxel and cabazitaxel), he died of the disease 3 months after the diagnosis of ASCP, or 13 months after the initial diagnosis of prostatic adenocarcinoma. His PSA values remained ≤ 0.2 ng/mL. CTCs from the patient’s blood (collected before starting docetaxel) were analyzed and genomically assessed. It showed 5 cytokeratin (CK)+ CTCs, 14 CK− CTCs, and 8 CTC clusters, per 10 mL. Next-generation sequencing identified a total of 14 mutations in 8 oncogenes or tumor suppressor genes: PIK3CB, APC, CDKN2A, PTEN, BRCA2, RB1, TP53, and CDK12. Of 14 mutations, 9 (64%) were detected on CK− CTCs and 5 (36%) were detected on CK+ CTCs. Conclusions This is the first report of CTC analysis and genomic assessment in ASCP. Although the prognosis of ASCP is dismal due to lack of effective treatment, genomic analysis of CTCs might lead to effective treatment options and improved survival.

Abstract
A 51-year-old man with a history of renal cell carcinoma presented with sudden aphasia, right hemiparesis, and dysesthesia. MRA showed left middle cerebral artery occlusion, and he was diagnosed with acute ischemic stroke and treated with intravenous recombinant tissue plasminogen activator and endovascular thrombectomy. The pathological diagnosis of the retrieved thrombus was consistent with the already-known pathological findings of the primary renal cell carcinoma. Therefore, a diagnosis of cerebral embolism caused by tumor cells was made. The pathological findings of the retrieved thrombi were important in determining the cause of ischemic stroke.

Abstract
OBJECTIVES Thymic epithelial tumors are the most common adult mediastinal tumors; however, their growth mechanism remains relatively unknown. Among the JAK/STAT pathway-related proteins, which control various intracellular events, STAT3 is deeply involved in cell proliferation. Constitutive activation of STAT3 and the resulting overexpression of cyclin D1 have been confirmed in various tumors, but have not been thoroughly investigated in thymic epithelial tumors. In this study, we immunohistochemically examined STAT3 activation, cyclin D1 expression, and JAK3 activation in thymic epithelial tumors and statistically analyzed their correlation with clinicopathological features. METHODS Formalin-fixed paraffin-embedded specimens of 94 thymic epithelial tumors surgically resected at Kyorin University Hospital between 2005 and 2018 were included in this study. pSTAT3, cyclin D1, and pJAK3 were immunohistochemically examined, and the correlation with histology, Masaoka stage, and survival time was statistically analyzed. RESULTS Cyclin D1 was found to be significantly overexpressed in the STAT3-activated group. This phenomenon was associated with histology and Masaoka stage. JAK3 was also activated in thymic epithelial tumors; however, JAK3 and STAT3 activation were not always correlated. Using survival time analysis, the STAT3-activated group, cyclin D1-expressed group, and JAK3-activated group had significantly lower progression-free survival times than those for both the non-activated and non-expressed groups. CONCLUSIONS STAT3 activation may promote cyclin D1 overexpression in thymic epithelial tumors, and intracellular signaling pathways other than JAK3 may be involved in STAT3 activation. STAT3 activation, cyclin D1 overexpression, and JAK3 activation are biomarker candidates that indicate clinically poor prognosis.

Abstract
BACKGROUND Sentinel lymph node biopsy is widely applied for the management of clinically node-negative breast cancer, and a radioisotope with a blue dye are most often used as tracers. Fluorescence of indocyanine green could also potentially be used as tracer. This study aimed to demonstrate the long-term survival results of fluorescence-guided sentinel lymph node biopsy. PATIENTS AND METHODS Patients with clinically node-negative breast cancer who underwent surgery as initial treatment were included in this study. Both fluorescence of indocyanine green and indigo carmine blue dye were used as tracers. Axillary lymph node dissection was omitted unless metastasis was pathologically proven in sentinel nodes. Breast cancer recurrence and death were recorded and prognostic factors were identified using disease-free survival and overall survival data. RESULTS A total of 565 patients were analyzed. There were 14 (2.5%) patients whose sentinel nodes could not be identified, yielding an identification rate of 97.5%. Axillary dissection was performed in 90 patients. Forty-three recurrences including 6 ipsilateral axilla recurrence and 13 deaths were observed during the median 83 months of follow-up period. Seven-year disease-free and overall survival were 92.4% and 97.3%, respectively. Multivariate analyses demonstrated that pre-menopausal status and invasive lobular carcinoma were significant unfavorable prognostic factors of disease-free survival. Half of ipsilateral axilla recurrences occurred within 5 years after surgery and these recurrences were correlated with inappropriate adjuvant therapy. CONCLUSION Fluorescence-guided sentinel lymph node biopsy demonstrated favorable prognostic results and could be alternative to the radioisotope for clinically node-negative breast cancer.

Abstract
BACKGROUND/AIM The telomerase reverse transcriptase (TERT) promoter has a regulatory single nucleotide polymorphism (rSNP), rs2853669, and occasionally shows point mutations C228T and C250T. Although C228T and C250T have been well examined to increase TERT promoter activity and are known as risk factors for thyroid carcinoma, the significance of rs2853669 has not been well investigated. This study aimed to clarify the influence of rs2853669 on TERT promoter activity in thyroid carcinoma cells. MATERIALS Seven of 8 examined thyroid cell lines had rs2853669, 5 had C228T, and 1 had C250T. RESULTS Three papillary thyroid carcinoma cell lines, harboring both rs2853669 and C228T, showed higher TERT mRNA expression on real-time PCR than the other cell lines. Anaplastic thyroid carcinoma cell lines, in contrast, showed variable TERT mRNA expression depending on the combination of rs2853669, C228T, and C250T. Luciferase assays, performed to compare the influences of rs2853669, C228T, and C250T on TERT promoter activity in thyroid carcinoma, showed that rs2853669, as well as C228T, increased the promoter activity, and the combination of rs2853669 and C228T increased the promoter activity even more strongly than C228T alone. CONCLUSION We conclude that the presence of rs2853669 within the TERT promoter could be as significant as the C228T mutation in thyroid carcinoma.

Abstract
Germline pathogenic ETV6 variants have been discovered in families with inherited thrombocytopenia and predisposition to hematological and solid malignancies. We present a patient with short stature who was initially diagnosed with chronic immune thrombocytopenia. Subsequently, the patient developed acute lymphoblastic leukemia, followed by mammary analog secretory carcinoma. Sequencing analysis identified an ETV6 c.641C > T (p.Pro214Leu) germline variant. The variant protein exhibited attenuated nuclear localization, increased protein degradation, and reduced transcription repression function. Our findings suggest that the ETV6 gene should be sequenced in patients with inherited thrombocytopenia and malignancy, and emphasize the importance of careful follow-up to identify secondary cancer in patients with pathogenic ETV6 variants.

Abstract
BACKGROUND Liquid-based cytology (LBC) allows immunohistochemistry (IHC), fluorescence in situ hybridization, and molecular testing to be performed in fixed cell materials. We examined the feasibility of subtyping and EGFR mutation testing of bronchoscopic samples from patients with lung cancer using cell blocks (CB) based on LBC fixation (LBC-CB). METHODS We included 35 consecutive patients with peripheral lung nodules who underwent endobronchial ultrasonography with a guide sheath in our hospital. Thirty of these patients were diagnosed with lung cancer by obtaining cytological samples. Cytological subtyping was performed with IHC using LBC-CB, and the Cobas EGFR Mutation Test ver. 2 was performed using extracted genomic DNA from the LBC-CB, formalin-fixed paraffin-embedded (FFPE) tissue, and matched plasma. RESULTS Of the 30 cases, 25 were classified cytomorphologically as adenocarcinoma (ADC, n = 17) and squamous-cell carcinoma (SQCC, n = 8). The remaining five cases were classified by IHC as favor ADC (n = 3) and favor SQCC (n = 2) according to the WHO criteria. In the final ADC group (n = 20), EGFR mutations on the LBC-CB were identified in eight cases (40%; 1 exon 19 deletion, 6 L858R, and 1 L861Q). Mutations in FFPE samples were identified in seven cases (35%) at the same site in each case. Plasma EGFR mutations were identified in four cases (20%) at the same site. The CB detection rate was higher than for FFPE and plasma. CONCLUSION LBC-CB is suitable for subtyping and EGFR mutation testing in lung cancers.

Abstract
Papillary thyroid carcinoma (PTC) is the most common thyroid malignancy. Point mutations in the telomerase reverse transcriptase (TERT) promoter, C228T and C250T and oncogene BRAFV600E have been investigated as risk factors for PTC. However, little research has been done on the single nucleotide polymorphism rs2853669 in the TERT promoter in PTC. This study aimed to clarify the clinicopathological significance of rs2853669 in Japanese patients with PTC. The genetic frequencies of rs2853669, C228T, C250T and BRAFV600E were investigated in 58 patients with PTC and compared with the clinicopathological parameters of PTC. rs2853669, C228T, C250T and BRAFV600E were found in 58.6%, 17.2%, 5.2% and 37.0% of the PTC patients, respectively. PTC with rs2853669 and C228T were associated only with tumor sizes larger than 2.0 cm (P < 0.05). Furthermore, the coexistence of rs2853669 and C228T was strongly associated with tumor size (P < 0.01), with an odds ratio of 6.4 (P < 0.05). We showed that rs2853669, as well as C228T, may be a risk factor for the aggressiveness of PTC, and the coexistence of these mutations might represent greater risk.

Abstract
Follicular thyroid neoplasm is a common tumor, and consists of follicular thyroid adenoma (FTA) and carcinoma (FTC). The mechanisms of tumor development of FTA and FTC are not well-understood. Single-nucleotide polymorphisms (SNPs) and point mutations in the telomerase reverse transcriptase (TERT) promoter have been associated with tumor development of many cancers. In order to clarify the significance of TERT promoter SNPs and mutations, including rs2853669 (-245T>C), C228T, and C250T, we analyzed 59 FTA patients and 19 FTC patients. Rs2853669 was found in 67.8% (40/59) and 57.9% (11/19) of FTAs and FTCs, respectively, and homozygous rs2853669 (CC) was more frequently found in FTC than in FTA. Furthermore, in FTA, rs2853669 was significantly associated with tumor size greater than 2.0 cm (P < 0.05). C228T was found in 5.1% and 36.8% of FTAs and FTCs, respectively. Frequencies of rs2853669 or/and C228T mutation were 71.2% in FTAs and 73.7%, in FTCs, and were significantly associated with larger tumor sizes in FTAs (P < 0.05). Rs2853669 is considered to be associated with tumor development in FTA and FTC.

Abstract
BACKGROUND Anomalous left coronary artery from the pulmonary artery (ALCAPA) is a rare congenital coronary anomaly that results in high mortality if left untreated. Our aim was to extend our knowledge of the histological, angiographic, and clinical characteristics of ALCAPA in order to deepen our understanding of this rare entity. CASE PRESENTATION We were involved in the assessment, treatment, and pathological evaluation of two adult ALCAPA patients who were rescued from ventricular fibrillation and then surgically treated to establish a dual coronary artery system. Histological studies indicated various chronic ischemic changes in the myocardium, patchy fibrosis, and severely thickened arteriolar walls in both ventricles. The first patient is alive and well 11.5 years after surgical correction without any implantable cardioverter defibrillator (ICD) activations. The second patient required re-do surgery 9 months after the initial operation but subsequently died. Histologically, chronic ischemic alteration of the myocardium and thickened arteriolar walls persisted even after surgical correction, and coronary angiography (CAG) showed an extremely slow flow phenomenon even after surgical correction in both patients. The average postoperative opacification rate in the first case was 7.36 + 1.12 (n = 2) in the RCA, 3.81 + 0.51 (n = 3) in the left anterior descending (LAD) artery, and 4.08 + 0.27 (n = 4) in the left circumflex (LCx) artery. The slow flow phenomenon may represent persistent high arteriolar resistance in both ventricles. CONCLUSIONS Seldom reported or new findings in adult ALCAPA were identified in two cases. More frequent diagnosis of adult ALCAPA can be expected because of the widespread availability of resuscitation and more advanced diagnostic modalities. Accumulation of pathological and clinical findings and confirmation of the long-term follow-up results after treatment may contribute to expanding our knowledge of this rare entity and establishing optimal treatment.

Abstract
Iodide transport and storage in the thyroid follicles is crucial for thyroid hormone synthesis. Pendrin, the iodide exporter that transports iodide to thyroid follicles, is responsible for Pendred syndrome, a disorder characterized by congenital hypothyroidism and hearing loss. However, thyroid hormone levels are basically normal in patients with Pendred syndrome, indicating the presence of another unknown iodide transporter. Here, we show that SLC26A7 is a novel iodide transporter in the thyroid. We observe that SLC26A7 is specifically expressed in normal thyroid tissues and demonstrate its function in iodide transport. Using whole-exome sequencing, we also find a homozygous nonsense mutation in SLC26A7 (c.1498 C > T; p.Gln500Ter) in two siblings with congenital goitrous hypothyroidism. The mutated SLC26A7 protein shows an abnormal cytoplasmic localisation and lacks the iodide transport function. These results reveal that SLC26A7 functions as a novel iodide transporter in the thyroid and its dysfunction affects thyroid hormonogenesis in humans and causes congenital goitrous hypothyroidism.

Abstract
Breast cancer has been suggested to have two distinct driving mechanisms: the hormone receptor and the growth factor receptor pathways. We hypothesized that each driving system produces a different expression pattern of estrogen-regulated genes, such as progesterone receptor, in proliferating cells. Progesterone receptor and Ki67 expressions were assessed by dual-fluorescence immunohistochemistry in estrogen-receptor-positive breast cancer tissues. Two distinct proliferating cell populations were observed: progesterone-receptor-positive and progesterone-receptor-negative. In the training cohort, tissues with progesterone-receptor-positive proliferating cells were associated with lower grade and better disease-free survival (p = 0.0055 and 0.0026, respectively). These associations were confirmed in the validation cohort from the neoadjuvant endocrine trial JFMC34 (p = 0.033 and 0.0003, respectively). In the validation cohort, patients with progesterone-receptor-positive proliferating cells responded better to endocrine therapy and had a lower Oncotype DX Recurrence Score. In the multivariate analysis, progesterone receptor status of proliferating cells, but not progesterone receptor or Ki67 alone, was an independent predictor of disease-free survival in both cohorts (p = 0.0043 and 0.0026). In conclusion, the progesterone receptor status of proliferating cancer cells was associated with histological grade and Recurrence Score, and a potent prognostic factor in estrogen-receptor-positive breast cancers. Results suggest that different driving systems generate different expression patterns of progesterone receptor in proliferating cancer cells. Further studies are warranted to validate the findings.

Abstract
Background Primary central nervous system lymphoma (PCNSL) remains an aggressive and refractory tumor despite high-dose methotrexate-based chemo-radiotherapy. Age and performance status have been shown to be important clinical prognostic factors, however others, especially molecular factors, affecting the prognosis are still uncertain. Methods We investigate clinical, neuroimaging and immunohistochemical data in tissue from 41 PCNSL patients treated primarily with methotrexate-based chemo-radiotherapy and evaluate the influence of potential prognostic factors on clinical outcome as well as correlation among these factors. Results Median progression-free survival (PFS) and overall survival (OS) were 29 and 73 months, respectively. Expression of the mismatch repair (MMR) proteins, MLH1, MSH2, MSH6 and PMS2, correlated tightly with each other and high expression of MSH2 was significantly associated with better OS and PFS (P = 0.005 and P = 0.007), while methotrexate metabolism-related proteins did not affect survival. In addition, low expression of PMS2 was an independent predictor of methotrexate resistance (P = 0.039). Among neuroimaging findings, involvement of the fornix and tegmentum/velum were significantly associated with poorer OS (P < 0.001 and P = 0.013) and PFS (P = 0.014 and P = 0.043, respectively). Germinal center B cell (GCB)-PCNSL subtype as opposed to non-GCB subtype, tended toward better survival. Regarding oncogenes, cMYC-positive cases showed unfavorable OS (P = 0.046). By multivariate analysis, MSH2 and involvement of the fornix were independent predictors for both OS and PFS, whereas tegmentum/velum location and cMYC expression were significantly associated with OS. Conclusions Although further studies are needed, these results suggest that MMR protein expression, as well as specific deep locations and cMYC expression, may be a novel prognostic and predictive markers for PCNSL.

Abstract
Well-differentiated thyroid carcinomas have driver mutations involving growth factor receptor-tyrosine kinases (RTKs) or their intracellular signaling pathway, that is, the mitogen-activated protein kinase (MAPK) pathway. Sorafenib is a multikinase inhibitor of RTKs and the MAPK pathway and has recently been used for the treatment of unresectable well-differentiated thyroid carcinoma. In normal thyroid follicular cells, stimulation of the thyroid-stimulating hormone (TSH) receptor activates the cyclic adenosine monophosphate (cAMP) pathway and promotes cell growth as well as hormonal secretion. However, an adenylyl cyclase (AC) activator, forskolin, has been reported to suppress the growth of thyroid carcinoma cells. To clarify the roles of the MAPK and cAMP pathways in proliferation of well-differentiated thyroid carcinoma cells, we compared the effects of sorafenib and forskolin in in vitro models. Sorafenib inhibited constitutive activation of the MAPK pathway, cyclin-dependent kinase 4 (CDK4), and phosphorylated retinoblastoma protein (RB) in 3 well-differentiated carcinoma cell lines, but it did not show sufficiently effective suppression of cell growth. Forskolin significantly suppressed the growth of all 3 cell lines and also activated the cAMP pathway and inhibited expression of cyclin D1. Our results suggest that activation of the cAMP pathway could be more potent than activation of the MAPK pathway in suppressing proliferation of well-differentiated thyroid cancer cells. We postulate that the AC activator suppresses growth of thyroid carcinoma cells through undetermined mechanisms.

Abstract
We describe a 74-year-old man with a nodular goiter accompanied by an incidental sporadic minute medullary thyroid carcinoma (MTC). Histopathologically, the MTC was a well-defined 1.7 mm tumor in the upper one-third right lobe, with solid cell nests (SCNs) adjacent to the MTC. C-cells were scattered mainly around the SCNs, but C-cell hyperplasia was not evident in the background thyroid. The MTC cell phenotype was immunohistochemically identical to background C-cells, but was completely different from the SCN main cells. Direct DNA analyses of isolated MTC paraffin-embedded specimens revealed two RET proto-oncogene missense point mutations in exon 11 (i.e., C630R and C634W). The non-tumor thyroid tissue did not reveal any mutations. This study reports the smallest case of sporadic MTC with a double RET somatic mutation, substantiating that RET mutations can occur during a very early stage of carcinogenesis. The combined presence of C630R and C634W represent a novel somatic mutation in sporadic MTC. The present case indicates that the sporadic MTC originated from the surrounding C-cells of the SCNs without C-cell hyperplasia and that the SCN main cells may not be able to develop into an MTC.

Abstract
The multi-step progression of colorectal cancer through precancerous lesions (adenoma and dysplasia) is associated with cumulative molecular alterations, a number of which have also been demonstrated to be present in morphologically normal transitional mucosa adjacent to colorectal cancer. The cytoskeletal protein cytokeratin 7 (CK7) and the receptor tyrosine kinase, KIT proto-oncogene receptor tyrosine kinase (CD117), encoded by the proto-oncogene c-Kit, are lacking in normal colorectal crypt epithelium and are aberrantly expressed in a subset of colorectal cancer. The aim of the present study was to evaluate the expression of CK7 and CD117 in morphologically normal transitional mucosa adjacent to colorectal cancer. Immunohistochemical staining for CK7 and CD117 was performed in the mucosa adjacent to five groups of surgically resected colorectal tumors [low-grade adenoma, high-grade adenoma, mucosal adenocarcinoma, small-sized invasive adenocarcinoma (≤2 cm) and large-sized invasive adenocarcinoma (>2 cm)]. CK7 was expressed in the mucosa adjacent to a subset of colorectal tumors, and the positivity ratio increased according to tumor grade from low-grade adenoma up to small-sized invasive adenocarcinoma (61.2%). However, the positivity ratio of CK7 in the mucosa adjacent to the large-sized invasive adenocarcinoma (25.0%) was significantly lower compared with that of the next lower grade. CD117 was also expressed in the mucosa adjacent to a subset of colorectal tumors. In contrast to CK7, the positivity ratio of CD117 increased according to tumor grade from low-grade adenoma all the way through to the large-sized invasive adenocarcinoma (45.0%). Based on these results, the mechanism of CK7 and CD117 expression in the transitional mucosa adjacent to colorectal cancer may be different, and analysis of their individual expression may provide novel insights into the development and progression of colorectal cancer.

Abstract
Background Biliary tract cancer is a rare malignancy that carries poor prognosis. Complete surgical resection is the only curable treatment. However, biliary tract cancer patients are often diagnosed with advanced stages and treated in systemic chemotherapy or palliative treatment settings rather than curative surgery. Case presentation This case report describes a pathological complete response of advanced biliary tract cancer achieved after 2 years of intensive combined chemotherapy with gemcitabine and S-1. A 70-year-old female patient who developed severe stenosis in the middle common bile duct with para-aortic lymph nodes swelling was diagnosed with advanced extrahepatic biliary tract cancer that includes metastatic para-aortic lymph nodes and treated with combined chemotherapy of gemcitabine and S-1. After 32 courses of the combined chemotherapy, substantial shrinkage of these enlarged lymph nodes were confirmed and she underwent pylorus-preserving pancreaticoduodenectomy. The pathological examination revealed no viable neoplastic cells in the common bile duct or lymph nodes. She did not receive any further adjuvant chemotherapy. No recurrent lesions have been detected for 48 months after the primary surgery. Conclusions This case shed light on the probability of conversion and/or adjuvant surgery for biliary tract cancer with novel systemic chemotherapy regimens.

Abstract
Background: We previously reported about immune suppression in breast cancer patients at this meeting. In brief, tumor tissue specimens and peripheral blood mononuclear cells (PBMC) were analyzed in 50 early or advanced breast cancer (BC) patients. To compare between 38 early and 12 advanced BC cases, CD163-positive tumor cells and CCR4-positive tumor cells were detected more frequently in advanced cases than in early cases. Regulatory T (Treg) cells in PBMC significantly increased in percentage of the population in 37 BC patients than in 21 healthy volunteers (AACR 2011). In addition, several cytokines were examined in that cohort and plasma IL-17A had significantly higher levels in early BC than in advanced BC (AACR 2013). Then, we examined their prognosis and immunological profile.
Patients and methods: Treg cells were examined by counting CD4+CD25highCD127low/-cells in PBMC with flow cytometry analysis. Immunohistochemical evaluation of tumor specimens was performed with monoclonal antibodies of HLA-ABC and DR, CD56, CD68, CD83, CD163 and CCR4. The number of stained cells was analyzed using a semiquantitative ordinal scale ranging from 0 to 3 (0, +/-, ++, +++). Human IL-2, IL-4, IL-6, IL-10, TNF, INFγ and IL-17A were measured using cytometric beads array system. Most patients received chemotherapy, hormonal therapy, and/or anti-HER2 therapy on the basis of intrinsic subtype and breast irradiation after breast-conserving surgery.
Results and discussions: At the median follow-up of 7 years after blood sample collection, only 2 operable patients relapsed and 3 patients including 2 cases of stage IV died of disease. Of 5 cases of stage IV or recurrent BC, CD163 and/or CCR4 were strongly stained positive in tumor cells. There were significant differences of staining intensity in CD163 and CCR4-positive tumor cells between those cases and the rest 45 cases (p<0.01 at Chi-square test). However, other immune cell profiles, Treg cells in PBMC and cytokines in plasma had no trend between them. Several reports demonstrated that cancer patients with CD163-positive tumor-infiltrating macrophages and CD163-positive tumor cells had poor prognosis due to tumor-associated macrophage. Phenotypic macrophage traits in cancer cells, like CD163 expression, may be explained by heterotypic cell fusion between monocytes/macrophages and cancer cells.
Conclusion: Targeted therapy against M2 macrophage or CCR4 is considered as a promising strategy of advanced breast cancer.

Abstract
Several proteins implicated in hormonogenesis of the adrenal cortex have alternatively spliced isoforms, which respond differently to adrenocorticotropic hormone (ACTH). Heterogeneous nuclear ribonucleoproteins A2 and B1 are among the abundant pre-mRNA-binding proteins involved in alternative splicing. We examined the expression of A2 and B1 in normal adrenal cortex and tumors. B1 was variably expressed in the zona fasciculata-reticularis, although A2 was diffusely expressed in the three zones. B1 was more abundant in compact cells than clear cells, and B1 expression was frequent in the zona reticularis, which consists mainly of compact cells. In three kinds of cortical adenomas autonomously producing hormones, B1 was generally overexpressed and there were no significant differences among them. In cortisol-producing tumors, non-tumor parts of the cortex, which were generally atrophic due to low ACTH, had less B1 protein than normal adrenals. These results suggested a correlation between B1 expression and the hormonal activity responding to ACTH. In vitro ACTH stimulation induced a biphasic expression of B1 in an H295R cortical carcinoma cell line, and it paralleled hormonogenesis. Conclusively, B1 expression varied in relation to the hormonal activity responding to the ACTH, and it may provide a key to elucidating the splicing mechanisms involved in hormonogenesis.

Abstract
Mechanisms of endocrine secretory granule (SG) formation in thyroid C cells and medullary thyroid cancer (MTC) cells have not been fully elucidated. Here we directly demonstrated that PROX1, a developmental homeobox gene, is transcriptionally involved in SG formation in MTC, which is derived from C cells. Analyses using gene expression databases on web sites revealed that, among thyroid cancer cells, MTC cells specifically and highly express PROX1 as well as several SG-forming molecule genes. Immunohistochemical analyses showed that in vivo MTC and C cells expressed PROX1, although follicular thyroid cancer and papillary thyroid cancer cells, normal follicular cells did not. Knockdown of PROX1 in an MTC cells reduced SGs detected by electron microscopy, and decreased expression of SG-related genes (chromogranin A, chromogranin B, secretogranin II, secretogranin III, synaptophysin, and carboxypeptidase E). Conversely, the introduction of a PROX1 transgene into a papillary thyroid cancer and anaplastic thyroid cancer cells induced the expression of SG-related genes. Reporter assays using the promoter sequence of chromogranin A showed that PROX1 activates the chromogranin A gene in addition to the known regulatory mechanisms, which are mediated via the cAMP response element binding protein and the repressor element 1-silencing transcription factor. Furthermore, chromatin immunoprecipitation-PCR assays demonstrated that PROX1 binds to the transcriptional regulatory element of the chromogranin A gene. In conclusion, PROX1 is an important regulator of endocrine SG formation in MTC cells.

Abstract
BACKGROUND Cigarette smoking is considered to be one of major causes of acute worsening of asthma as well as chronic obstructive pulmonary disease (COPD). Macrolide antibiotics have been reported to reduce the risk of exacerbations of COPD, and possibly neutrophilic asthma. However, the effect of clarithromycin (CAM) on pulmonary inflammation caused by short term exposure to cigarette smoke still remains to be investigated. METHODS C57BL/6J female mice were daily exposed to tobacco smoke using a tobacco smoke exposure system, or clean air for 8 days, while simultaneously treated with either oral CAM or vehicles. Twenty four hours after the last exposure, mice were anaesthetized and sacrificed, and bronchoalveolar lavage (BAL) fluids were collected. Cellular responses in BAL fluids were evaluated. Levels of cytokine mRNA in the lung tissues were measured by quantitative RT-PCR. Paraffin-embedded lung tissues were evaluated to quantitate degree of neutrophil infiltration. RESULTS The numbers of total cells, macrophages and neutrophils in the BAL fluid of smoke-exposed mice were significantly increased as compared to clean air group. These changes were significantly ameliorated in CAM-treated mice. The lung morphological analysis confirmed decrease of neutrophils by CAM treatment. Studies by quantitative PCR demonstrated CAM treatment significantly reduced lung expression levels of IL-17A, keratinocyte-derived chemokine (KC), granulocyte-macrophage colony stimulating factor (GM-CSF) and MMP-9 induced by cigarette smoke. CONCLUSION We demonstrate that CAM administration resolves enhanced pulmonary inflammation induced by short term cigarette smoke exposure in mice.

Abstract
One-third of lung malignancies demonstrate a proneural/neuroendocrine phenotype or type of differentiation. However, it has not been clearly elucidated how proneural/neuroendocrine differentiation is controlled in lung cancers. We recently demonstrated that the POU3F2 gene plays a significant role in proneural/neuroendocrine differentiation of lung cancers. Because class III POU genes (POU3F1, POU3F2, POU3F3, and POU3F4) and class IV POU genes (POU4F1, POU4F2, and POU4F3) share similar properties in neural development, we analyzed the association between class III/IV POU genes and a proneural/neuroendocrine phenotype in lung cancers using seven small cell lung cancer (SCLC) cell lines and twelve non-SCLC (NSCLC) cell lines. Class III/IV POU gene expression was generally restricted to SCLC cells. However, the forced expression of class III/IV POU genes in the NSCLC cell lines induced the expression of neuroendocrine-specific markers (neural call adhesion molecule 1, synaptophysin, and chromogranin A) and proneural transcription factors (achaete-scute homolog-like 1, NeuroD1, and thyroid transcription factor 1) in various degrees. Furthermore, each class III/IV POU gene induced other class III/IV POU genes, suggesting the mutual induction of class III/IV POU genes. These findings suggest that the expression of class III/IV POU genes is important for the proneural/neuroendocrine differentiation of lung cancer cells.

Abstract
A woman in her 50s was referred to our department with the chief complaint of nasal congestion and pharyngeal discomfort. The patient had been diagnosed with sleep apnea at the Department of Internal Medicine, and had undergone nasal continuous positive airway pressure (nCPAP) therapy, but her response to the treatment was poor. A cystic lesion occupying the nasopharynx, which was detected by nasopharyngeal fiberscopy, computed tomography, and magnetic resonance imaging, was thought to be the cause of the nasal congestion, pharyngeal discomfort, and obstructive sleep apnea syndrome (OSAS). Consequently, the patient underwent extirpation of the lesion under general anesthesia for the purpose of obtaining a definitive diagnosis as well as for treatment of the nasopharyngeal tumor. The diagnosis of intra-adenoid cyst was eventually made based on the pathological findings, which revealed lymphoid tissue accompanied by expansion of the crypt, as well as inflammatory cell infiltration with follicular hyperplasia. After the operation, the patient reported subjective improvement of her symptoms, and began to respond to the nCPAP therapy for her sleep apnea syndrome. Nasopharyngeal cysts, in particular adult intra-adenoid cyst, are relatively rare. The outcomes of the current case indicated that the presence of a nasopharyngeal cystic disease was hampering the nCPAP treatment of refractory OSAS.

Abstract
Lobular carcinoma in situ (LCIS) clinically constitutes a risk factor for the subsequent development of either invasive lobular carcinoma (ILC) or invasive ductal carcinoma (IDC). In order to approach the possibility of this common precursor of both ILC and IDC, we investigated combined lobular and ductal carcinomas. Thirty-two cases of lobular carcinoma were picked up out of 773 cases of operated breast carcinomas. The histopathological detailed re-examination using immunostain of E-cadherin and β-catenin revealed a rather high frequency of combined lobular carcinomas than previous reports. Clinicopathologically, combined lobular carcinomas were younger and smaller than pure lobular carcinomas, and the cytological atypia was relatively low. These results suggested that combined lobular carcinomas could be detected in the earlier stage of breast cancer. Furthermore, the lobular and ductal components of combined carcinomas coexisted in the neighborhood and were distributed contiguously. The immunohistochemical phenotypes of both components were accorded in most combined cases. A genetic analysis using methylation-specific PCR on the HUMARA gene demonstrated that the same allele was inactivated in both lobular and ductal components in all detectable cases of combined carcinoma. Therefore, it is reasonable to assume that both lobular and ductal components of combined carcinomas are clonal and derived from the LCIS as the common precursor lesion, which may contradict the conventional concept that the lobular and ductal carcinomas arise from distinct differentiation pathways.

Abstract
AIM OF THE STUDY Interleukin (IL)-10 is an anti-inflammatory cytokine, but its role in cigarette smoke (CS)-induced inflammation and chronic obstructive pulmonary disease (COPD) has not been fully elucidated. The purpose of this study was to investigate the effect of IL-10 deficiency on CS-induced pulmonary inflammation in mice in vivo and in vitro. MATERIALS AND METHODS IL-10-deficient and wild-type control mice with a C57BL6/J genetic background were exposed to CS, and inflammatory cells in bronchoalveolar lavage fluid (BALF) and mRNA of cytokines in lung were evaluated with enzyme-linked immunosorbent assay (ELISA) and reverse transcription polymerase chain reaction (RT-PCR). RESULTS During 12 days of daily CS exposure to wild-type mice, neutrophil counts in BAL fluid and tumor necrosis factor (TNF)-α mRNA expression were increased, peaked at day 8, and then declined on day 12 when the level of IL-10 reached its peak. In IL-10-deficient mice, neutrophil recruitment and TNF-α mRNA levels induced by CS exposure were significantly greater than those in wild-type mice. Keratinocyte-derived chemokine (KC; murine ortholog of human CXCL8) and granulocyte macrophage colony-stimulating factor (GM-CSF) mRNA levels or matrix metalloproteinase(MMP)-9 protein levels were not correlated with neutrophil count. CONCLUSIONS IL-10 had a modulatory effect on CS-induced pulmonary neutrophilic inflammation and TNF-α expression in mice in vivo and therefore appears to be an important endogenous suppressor of airway neutrophilic inflammation.

Abstract
We report a 48-year-old female who developed lymphoproliferative disorder (LPD) during treatment of rheumatoid arthritis (RA) with methotrexate (MTX). She presented with multiple tumors in the cervical lymph nodes (LNs), multiple lung shadows and round shadows in both kidneys with pancytopenia and a high CRP level. The LN showed CD8-positive T-cell LPD associated with Epstein-Barr (EB) virus-infected B-cells. Clonality assays for immunoglobulin (Ig) heavy chain and T-cell receptor gamma (TCRγ) were negative. The cessation of MTX without chemotherapy resulted in the complete disappearance of the tumors and abnormal clinical features. We compared this case with previously published ones and discuss the pathological findings, presuming that the proliferation of CD8 T-cells was a reactive manifestation to reactivated EB virus-infected B-cells.

Abstract
An 83-year-old man died of aspiration pneumonia 5 months after closure of atrial septal defect (ASD) with an Amplatzer atrial septal defect occluder (ASO). At autopsy, the device was scarcely covered by the endothelium. After percutaneous ASD closure, 6-month course of antiplatelet therapy and prophylaxis for endocarditis are recommended. However, the 6-month duration may not be sufficient for some patients. More data are required to clarify how long it takes for the ASO device to be endothelialized in the human body and to determine predictors of poor endothelialization.

Abstract
Thyroid transcription factor 1 (TTF1) plays crucial roles in thyroid, lung, and developing brain morphogenesis. Because TTF1-expressing neoplasms are generated from organs and tissues that normally express TTF1, such as the thyroid follicular epithelium and peripheral lung airway epithelium, TTF1 is widely used as a cell lineage-specific and diagnostic marker for thyroid carcinomas and for lung adenocarcinomas with terminal respiratory unit (TRU) differentiation. However, among lung neuroendocrine tumors, small-cell carcinomas (small-cell lung cancers (SCLCs)), most of which are generated from the central airway, also frequently express TTF1 at high levels. To clarify how SCLCs express TTF1, we investigated the molecular mechanisms of its expression using cultivated lung cancer cells and focusing upon neural cell-specific transcription factors. Both SCLC cells and lung adenocarcinoma cells predominantly expressed isoform 2 of TTF1, and TTF1 promoter assays in SCLC cells revealed that the crucial region for activation of the promoter, which is adjacent to the transcription start site of TTF1 isoform 2, has potent FOX-, LHX-, and BRN2-binding sites. Transfection experiments using expression vectors for FOXA1, FOXA2, LHX2, LHX6, and BRN2 showed that BRN2 substantially upregulated TTF1 expression, whereas FOXA1/2 weakly upregulated TTF1 expression. BRN2 and FOXA1/2 binding to the TTF1 promoter was confirmed through chromatin immunoprecipitation experiments, and TTF1 expression in SCLC cells was considerably downregulated after BRN2 knockdown. Furthermore, the TTF1 promoter in SCLC cells was scarcely methylated, and immunohistochemical examinations using a series of primary lung tumors indicated that TTF1 and BRN2 were coexpressed only in SCLC cells. These findings suggest that TTF1 expression in SCLC is a cell lineage-specific phenomenon that involves the developing neural cell-specific homeoprotein BRN2.

Abstract
BACKGROUND Axillary treatment of breast cancer patients is undergoing a paradigm shift, as completion axillary lymph node dissections (ALNDs) are being questioned in the treatment of patients with tumor-positive sentinel nodes. This study aims to develop a novel multi-institutional predictive tool to calculate patient-specific risk of residual axillary disease after tumor-positive sentinel node biopsy. METHODS Breast cancer patients with a tumor-positive sentinel node and a completion ALND from five European centers formed the original patient series (N = 1000). Statistically significant variables predicting nonsentinel node involvement were identified in logistic regression analysis. A multivariable predictive model was developed and validated by area under the receiver operating characteristics curve (AUC), first internally in 500 additional patients and then externally in 1068 patients from other centers. All statistical tests were two-sided. RESULTS Nine tumor- and sentinel node-specific variables were identified as statistically significant factors predicting nonsentinel node involvement in logistic regression analysis. A resulting predictive model applied to the internal validation series resulted in an AUC of 0.714 (95% confidence interval [CI] = 0.665 to 0.763). For the external validation series, the AUC was 0.719 (95% CI = 0.689 to 0.750). The model was well calibrated in the external validation series. CONCLUSIONS We present a novel, international, multicenter, predictive tool to assess the risk of additional axillary metastases after tumor-positive sentinel node biopsy in breast cancer. The predictive model performed well in internal and external validation but needs to be further studied in each center before application to clinical use.

Abstract
Abstract
Background: Recent multi-disciplinary treatments of breast cancer (BC) could decrease the mortality rate, but successful immune therapy remains uncertain. To explore new strategy of immune therapy of BC, we are investigating about host-tumor immune response in BC patients. Materials and methods: Tumor tissue specimens and peripheral blood mononuclear cells (PBMC) were obtained from early and advanced BC patients. PBMC were also collected from healthy volunteers. Regulatory T (Treg) cells were examined by counting CD4+CD25highCD127low/−cells in PBMC with flow cytometry analysis. Immunohistochemical evaluation of tumor specimens was performed with monoclonal antibodies of HLA-ABC and DR, CD56, CD68, CD83, and CD163. The number of stained cells was analyzed using a semiquantitative ordinal scale ranging from 0 to 3 (0, +/−, ++, +++). Results: HLA-ABC and DR were stained negative in 44% and 82% of 50 BC cases. When host-tumor immune response were compared between 38 early BC cases and 12 advanced BC cases, numbers of CD68-positive cells significantly increased in peripheral tumor tissues of advanced BC cases than in those of early BC cases (92% versus 53%). CD163-positive tumor cells were also detected more frequently in advanced BC cases than in early BC cases (75% versus 16%). There were no significant differences of distribution of CD4, CD8, CD56, and CD83-positive cells in early and advanced BC cases. Treg cells in PBMC significantly increased in percentage of the population in 37 BC patients than in 21 healthy volunteers (4.2% versus 2.5% of CD4-positive cells at mean value). Interestingly, Treg cells decreased in percentage of the population in 36 postoperative BC patients. Conclusions: Our results suggest that Treg cells render BC patients under immune suppression and M2 macrophage plays an important role of tumor progression. Targeted therapy against M2 macrophage may be a promising strategy of breast cancer.

Abstract
It has been suggested that various cytokines are associated with the pathophysiology of prostate carcinoma (Pca). We profiled ten cytokines (IL-1β, IL-2, IL-4, IL-5, IL-6, IL-8, IL-10, IL-12, IFN-γ and TNF-α) in the serum levels of 11 patients with organ-confined Pca, 15 with advanced Pca without cachexia, 8 with advanced Pca with cachexia (cachexia group) and 5 healthy males as controls. Cytokines were measured using a highly sensitive fluorescence microsphere system. Compared to the control group, serum levels of all cytokines were significantly higher in the cachexia group, and six cytokines (IL-1β, IL-2, IL-8, IL-12, TNF-α and IFN-γ) were significantly higher in the group with advanced Pca without cachexia. In the group with organ-confined Pca, only IL-1β and IL-12 levels were significantly higher compared to the control group. In the cachexia group, levels of all cytokines apart from TNF-α were significantly higher compared to the group with organ-confined Pca, and levels of four cytokines (IL-2, IL-4, IL-8 and IL-10) were significantly higher compared to the group with advanced Pca without cachexia. These results indicate that i) an aberrance imbalance of cytokine production was associated with the pathophysiology of Pca and cachexia, ii) cytokine profiles in Pca patients were distinct by disease stage, and iii) IL-1β and IL-12 may be applicable as early diagnostic indicators.
