RESUMEN
AIM: Patients with cancer experience various forms of psychological distress, including depressive symptoms, which can impact quality of life, elevate morbidity risk, and increase medical costs. Psychotherapy and pharmacotherapy are effective for reducing depressive symptoms among patients with cancer, but most patients prefer psychotherapy. This study aimed to develop an efficient and effective smartphone psychotherapy component to address depressive symptom. METHODS: This was a decentralized, parallel-group, multicenter, open, individually randomized, fully factorial trial. Patients aged ≥20 years with cancer were randomized by the presence/absence of three cognitive-behavioral therapy (CBT) skills (behavioral activation [BA], assertiveness training [AT], and problem-solving [PS]) on a smartphone app. All participants received psychoeducation (PE). The primary outcome was change in the patient health questionnaire-9 (PHQ-9) total score between baseline and week 8. Secondary outcomes included anxiety. RESULTS: In total, 359 participants were randomized. Primary outcome data at week 8 were obtained for 355 participants (99%). The week 8 PHQ-9 total score was significantly reduced from baseline for all participants by -1.41 points (95% confidence interval [CI] -1.89, -0.92), but between-group differences in change scores were not significant (BA: -0.04, 95% CI -0.75, 0.67; AT: -0.16, 95% CI -0.87, 0.55; PS: -0.19, 95% CI -0.90, 0.52). CONCLUSION: As the presence of any of the three intervention components did not contribute to a significant additive reduction of depressive symptoms, we cannot make evidence-based recommendations regarding the use of specific smartphone psychotherapy.

BACKGROUND: Cowden syndrome (CS) is an autosomal-dominant hereditary disorder caused by a germline PTEN variant and characterized by multiple hamartomas and a high risk of cancers. However, no detailed data on CS in Asian patients nor genotype-phenotype correlation have been reported. METHODS: We performed the first Japanese nationwide questionnaire survey on CS and obtained questionnaire response data on 49 CS patients. RESULTS: Patients included 26 females (median age 48 years). The incidence of breast, thyroid, endometrium, and colorectal cancer was 32.7%, 12.2%, 19.2% (among females), and 6.1%, respectively. The incidence of any cancers was relatively high among all patients (46.9%, 23/49), and particularly female patients (73.1%, 19/26), compared with previous reports from Western countries. Gastrointestinal (GI) polyps were more frequently found throughout the GI tract compared with previous studies. PTEN variants were detected in 95.6% (22/23) of patients; 12 in the N-terminal region (11 in phosphatase domain) and 10 in the C-terminal (C2 domain) region. The incidence of cancer in the C2 domain group was significantly higher than in the N-terminal region (phosphatase) group. All female patients with C2 domain variant had breast cancer. CONCLUSION: Our data suggest that Japanese patients with CS, particularly female patients and patients with C2 domain variant may have a high risk of cancers.

OBJECTIVE: To examine the association between surgical margin status and recurrence pattern in invasive vulvar Paget's disease. METHODS: This is a preplanned secondary analysis of a previously organized nationwide retrospective study in Japan (JGOG-1075S). Women with stage I-IV invasive vulvar Paget's disease who received surgical treatment from 2001-2010 were examined (n=139). Multivariable analysis was performed to assess local-recurrence, distant-recurrence, and all-cause mortality based on surgical margin status. RESULTS: The median age was 70 years. The majority had stage I disease (61.2%), and the median tumor size was 5.0cm. Nodal metastasis was observed in 15.1%. Simple vulvectomy (46.0%) was the most common surgery type followed by radical vulvectomy (28.1%). More than half received vulvar reconstructive surgery (59.0%). Positive surgical margin was observed in 35.3%, and close margin <1cm was observed in 29.5%. Vulvectomy type was not associated with surgical margin status (P=0.424). The median follow-up was 5.8 years. Positive surgical margin was associated with increased local-recurrence (5-year cumulative rates for positive versus negative margin: 35.8% versus 15.0%, P=0.010) but not distant-recurrence (18.3% versus 16.0%, P=0.567). Positive surgical margin was also associated with increased all-cause mortality (5-year overall survival rates for positive versus negative margin: 72.6% versus 88.2%, P=0.032). In multivariable analysis, positive surgical margin remained an independent factor associated with increased risk of local-recurrence (hazard ratio 2.80, 95% confidence interval 1.18-6.63) and all-cause mortality (hazard ratio 2.87, 95% confidence interval 1.20-6.83). CONCLUSION: Positive surgical margin appears to be common in invasive vulvar Paget's disease that is associated with increased local-recurrence and all-cause mortality risks. Role of alternative surgical technique or adjuvant therapy merits further investigation to improve local disease control.

AIM: The early and precise diagnosis and proper palliative treatment of bone metastasis is important for improving the quality of life of cervical cancer patients. The aim of this study was to clarify the clinical features, treatment modalities and prognosis of bone metastasis in cervical cancer patients in Japan. METHODS: The medical records of 75 cervical cancer patients with bone metastasis who were treated between January 2000 and December 2010 were retrospectively analyzed in a multi-institutional study. RESULTS: Fifty-four patients (72.0%) had a single bone metastasis. Bone metastases were found in the spine (46.7%) and pelvis (42.7%). Forty-three patients (57.3%) also had extra-osseous metastases. Most of the patients received radiotherapy, chemotherapy or both, but 25 patients (33.3%) received palliative care only. Bisphosphonates were given as palliative therapy to 25 patients (33.3%). The median overall survival after the diagnosis of bone metastasis was significantly shorter in patients with extra-osseous metastases than in those without extra-osseous metastases (14 vs 5 months; P < 0.05). The survival of patients who received chemotherapy following radiotherapy or concurrent chemoradiotherapy was significantly longer than that of the patients who received palliative care. On multivariate analysis, the presence of extra-osseous metastasis was an independent predictor of survival in patients with bone metastasis from cervical cancer. CONCLUSIONS: Multidisciplinary treatment might improve the prognosis of patients with bone metastasis who do not have extra-osseous lesions.

A 47-year-old man was admitted to the emergency room, half a day after having fallen down on his right cheek drunkenly onto a concrete block. Physical examination revealed that the contusion was limited to the right side of his face, only around the cheek, without trauma to the neck, chest or abdomen. But wide ranging tactile crepitus with severe swelling was present on his face and neck due to widely spread emphysema. Computed tomography (CT) scan revealed some fractures of maxillary antrum, facial and cervical emphysema spreading to the lower part of mediastinum. After a conservative treatment, he recovered without any severe systematic complication. It was found that the facial and cervical emphysema and pneumomediastimum completely disappeared on the follow-up CT scan, 18 days after the event.

AIM: To assess whether FOXL2 p.C134W mutation may play a role in the development of human ovarian tumors in the Japanese, we investigated the FOXL2 codon 134 mutation and protein expression of inhibin-α, bone morphogenetic protein 2 (BMP2) and follistatin (FST) in Japanese patients with granulosa cell tumor (GCT) of the ovary and other ovarian tumors. METHODS: We analyzed 114 tumor tissues from ovarian tumors, including 44 adult-type and two juvenile-type GCT of the ovary and 68 ovarian tumors by DNA sequencing. Immunohistochemistry was also performed in the adult and juvenile GCT tissues by immunostaining inhibin-α, BMP2 and FST. RESULTS: We found the FOXL2 p.C134W mutation in 27 out of 44 (61.4%) adult-type GCT of the ovary, but none in other ovarian tumors. Histologically, all of the adult-type GCT sections were positive for inhibin-α, and the expression of BMP2 and FST was detected in 14 of 44 (31.8%) and zero of 47 (0%), respectively. No significant differences regarding the diagnosed age, preoperative serum carbohydrate antigen 125 levels, or BMP2 immunopositivity between the FOXL2 p.C134W mutation-positive and mutation-negative were found in the adult-type GCT patients. CONCLUSION: Our findings suggest that FOXL2 p.C134W mutation-positive adult-type GCT of the ovary may not be common in the Japanese as compared to the previous data.

BACKGROUND: Leucine-rich alpha-2 glycoprotein (LRG) is a novel serum biomarker for inflammation in inflammatory bowel disease (IBD). This prospective study aimed to compare the value of LRG with C-reactive protein (CRP) and fecal calprotectin for evaluating clinical and endoscopic disease activity in patients with IBD. METHODS: At entry, clinical and endoscopic disease activity was assessed in 267 patients with IBD (ulcerative colitis [UC] 203; Crohn's disease [CD] 64), and the levels of LRG, CRP and fecal calprotectin were measured. The accuracy of the biomarkers for the detection of clinical and endoscopic disease activity was determined by the area under the receiver operating characteristic curve. RESULTS: Leucine-rich alpha-2 glycoprotein showed a significant relationship with the clinical and endoscopic severity in both UC and CD (both diseases, P < .0001). In the clinical assessment of UC, the accuracy of LRG was significantly higher than that of CRP (0.73 vs 0.63; P < .001). In the endoscopic assessment of UC, the accuracy of LRG was significantly higher than that of CRP (P = .01), but it was significantly lower than that of fecal calprotectin (P = .009; LRG, 0.80; CRP, 0.72; fecal calprotectin, 0.91). In the clinical and endoscopic assessment of CD, the accuracy was not significantly different between the biomarkers (clinical activity: LRG, 0.71; CRP, 0.64; fecal calprotectin, 0.66; in endoscopic activity: LRG, 0.79; CRP, 0.78; fecal calprotectin, 0.81). CONCLUSIONS: Leucine-rich alpha-2 glycoprotein is a reliable serum biomarker for the assessment of clinical and endoscopic disease activity in patients with IBD. It can be an alternative to CRP for the assessment of UC.

Birth cohort studies examining pregnancy and infant outcomes among adolescent and young adult (AYA) cancer survivors have been limited. The present study examined whether AYA cancer affects pregnancy outcomes of survivors and infectious diseases in their infants up to 1 year of age. Pregnant women were recruited for the Japan Environment and Children's Study, a nationwide, large-scale, prospective cohort study. The present study included 103,060 pregnant women and collected questionnaire-based data during the first and second/third trimester, and at 1 month, 6 months and 1 year after delivery. Adverse pregnancy outcomes and infectious diseases in infants up to 1 year of age were compared between AYA cancer survivors and pregnant women without a history of cancer using binominal logistic regression analyses and a multiple imputation method. Of 99,816 participants (3,244 were missing), 1,102 (1.1%) had a cancer history, including 812 participants (0.8%) with a history of cervical cancer. Among cervical cancer survivors, the adjusted (a)ORs were as follows: 3.25 (95% CI, 2.31-4.57; q=0.00) for a preterm birth <34 weeks' gestation; 2.82 (95% CI, 2.31-3.44; q=0.00) for a preterm birth <37 weeks' gestation; and 1.67 (95% CI, 1.36-2.06; q=0.00) for premature rupture of the membrane. Among the other cancer survivors, the aOR for caesarean section was 1.43 (95% CI, 1.10-1.87; q=0.0). Furthermore, lower respiratory tract inflammation in 1-year-old infants born by vaginal delivery increased significantly in cases with a history of cervical cancer (aOR, 1.77; 95% CI, 1.33-2.36; q=0.00). The present study identified the risk of lower respiratory tract inflammation in 1-year-old infants born by vaginal delivery in cervical cancer survivors for the first time. In addition, the frequency of caesarean section increased in all cancer survivors. No risk of congenital anomalies or other infections were found in the total group of cancer survivors.

RESUMEN
Introduction: Treatment-emergent small cell/neuroendocrine prostate cancer occurs predominantly in advanced or metastatic castration-resistant prostate cancer that arises when prostate adenocarcinoma is transformed after androgen deprivation therapy. The clinical course for the pathogenesis involved or associated genetic information have not been clearly elucidated. Case presentation: A Japanese male, 63-year-old, underwent a para-aortic lymph biopsy due to sudden severe bilateral leg edema, with a final diagnosis of stage IV prostate adenocarcinoma. He was initially responsive to upfront abiraterone with androgen deprivation therapy; however, relapse occurred in the liver and bone 10 months after initial treatment, with serum neuron-specific enolase elevation and without prostate-specific antigen elevation. Pathological findings of liver tumor revealed treatment-emergent small cell/neuroendocrine prostate cancer. FoundationOne® CDx was used for cancer-related gene profiling of liver tumor specimen; a BRCA2 mutation was identified. Conclusion: Early detection of this transformation and pathological diagnosis can improve patient survival when genetic mutations, including BRCA 1/2.
RESUMEN
The aim of the present study was to examine primary cilia in endometrial tissue during the menstrual cycle and to clarify their morphological changes with different grades of endometrial cancer. Images of fluorescence immunostaining taken by confocal microscopy were used to count the number of primary cilia in normal endometrium and endometrioid carcinoma Grade 1 and Grade 3 specimens. To examine the association between autophagy and ciliogenesis in endometrioid carcinoma, the expression of p62/Sequestosome-1, a selective substrate for autophagy, and oral-facial-digital syndrome 1 protein (OFD1), a protein associated with ciliogenesis, were examined using images of fluorescence immunostaining taken by confocal microscopy. The level of p62 expression was confirmed by western blotting. In proliferative and secretory endometrial stromal cells, the percentage of cells that were ciliated was 7.2 and 32.7% (95% confidence interval=21.61-39.79; P<0.01), and the length of the primary cilia was 1.24 µm and 2.34 µm (0.92-1.26; P<0.01), respectively. In stromal cells of endometrioid carcinoma Grade 1 and Grade 3, the percentage of ciliated cells was 13.5 and 2.9% (7.89-15.05; P<0.001), and the length of the primary cilia was 2.02 and 1.14 µm (0.76-0.99; P<0.001), respectively. In both normal menstrual cycle tissue and endometrial carcinomas, the percentage of primary cilia was lower and their length was shorter in tissues with higher proliferative potential. The expression of OFD1 was significantly higher in Grade 3 compared with Grade 1 as indicated by quantifying the intensity of the fluorescence images (133-12248; P=0.046). To the best of our knowledge, this is the first study concerning the distribution of primary cilia in normal endometrium and endometrial cancer tissues. Overall, fewer ciliated cells in the highly malignant endometrial cancer tissues may be associated not only to the proliferation of cancer cells, but also to the excessive accumulation of OFD1 due to dysfunctional autophagy.
RESUMEN
We report a case of ependymoma of the broad ligament occurring in a 21-year-old woman. CT and MRI findings showed a 40-mm-diameter, well-demarcated cystic mass with a lobulated solid component in the right pelvis. The solid component showed heterogeneous intermediate signal intensity on T2-weighted image and prolonged mild contrast enhancement. The tumor was resected and confirmed as ependymoma based on the histologic findings along with its immunohistochemical profile. To our knowledge, this is the first report of an adnexal ependymoma describing the precise radiological characteristics that resembled those of borderline or malignant epithelial ovarian tumors.
RESUMEN
Gastrointestinal cancer is one of the most common causes of mortality globally. The present study examined the influence of cytokine genetic polymorphisms [interleukin (IL)-1B C-31T, IL-1RN VNTR, IL-6 C-634G, IL-8 T-251A, IL-10 T-819C and IL-10 A-1082G] on clinical outcomes in patients with gastrointestinal cancer in palliative care. A total of 59 patients with gastrointestinal cancer who were admitted to Iga City General Hospital were analyzed. Genotyping was conducted using a polymerase chain reaction with confronting two-pair primers. Patients with at least one IL-1RN 2 allele demonstrated a significantly better survival (P=0.0275) while those with IL-6-634 G/G demonstrated a worse survival (P=0.0024). Multivariate analyses using the Cox proportional hazard model revealed that those with at least one IL-1RN 2 allele, IL-6-634 G/G or IL-10-1082 A/G had a significantly elevated adjusted hazard ratio of 9.20 (P=0.014), 41.01 (P=0.001) or 6.49 (P=0.046), respectively, compared with those with each homozygous wild-type polymorphism. In addition, the evaluation of weight loss by genotype revealed the potential influence of IL-10 T-819C genotype (P=0.072). IL-1RN, IL-6 and IL-10 polymorphisms were associated with the survival of patients with gastrointestinal cancer, suggesting the clinical feasibility of genetic testing in patients with gastrointestinal cancer in palliative care.
RESUMEN
OBJECTIVE: We conducted a retrospective, multi-institutional, collaborative study to accumulate cases of neuroendocrine carcinoma of the endometrium, to clarify its clinicopathologic features, treatment, prognosis and prognostic factors to collate findings to establish future individualized treatment regimens. To our knowledge, this is the largest case study and the first study to statistically analyze the prognosis of this disease. METHODS: At medical institutions participating in the Kansai Clinical Oncology Group/Intergroup, cases diagnosed at a central pathologic review as neuroendocrine carcinoma of the endometrium between 1995 and 2014 were enrolled. We retrospectively analyzed the clinicopathologic features, treatment, prognosis and prognostic factors of this disease. RESULTS: A total of 65 cases were registered from 18 medical institutions in Japan. Of these, 42 (64.6%) cases were diagnosed as neuroendocrine carcinoma of the endometrium based on the central pathological review and thus included in the study. Advanced International Federation of Gynecology and Obstetrics stages (stage III and IV) and pure type small cell neuroendocrine carcinoma cases had a significantly worse prognosis. Upon multivariate analysis, only histologic subtypes and surgery were significant prognostic factors. Pure type cases had a significantly worse prognosis compared to mixed type cases and complete surgery cases had a significantly better prognosis compared to cases with no or incomplete surgery. CONCLUSION: Our findings suggest that complete surgery improves the prognosis of neuroendocrine carcinoma of the endometrium. Even among cases with advanced disease stages, if complete surgery is expected to be achieved, clinicians should consider curative surgery to improve the prognosis of neuroendocrine carcinoma of the endometrium.

We used clinical data from Iga General Hospital to examine the association between polymorphisms in MTR (methionine synthase) A2756G (rs1805087), MTRR (methionine synthase reductase) His595Tyr (rs10380), MTHFR (methylenetetrahydrofolate reductase) C677T (rs1801133), MTHFR A1298C (rs1801131) and SHMT (serine hydroxymethyltransferase) C1420T (rs1979277), which are genes involved in folate metabolism, and the risk of weight loss in patients with gastrointestinal cancers, with the aim of establishing personalized palliative care for each patient based on genetic information. The data from 59 patients (37 males and 22 females) with gastrointestinal cancers who visited the outpatient clinic for cancer chemotherapy and palliative care at Iga General Hospital from December 2011 to August 2015 were analyzed. There was no significant association between the single nucleotide polymorphisms (SNPs) in the folate metabolizing genes examined and weight loss defined as weight loss of more than 5 percent or more than 10 percent during the first 6 months after initiation of chemotherapy. We did not detect any significant association between any of the SNPs examined and overall survival of patients. The present study indicated that these SNPs have relatively limited or no roles in the genesis of cachexia in patients with gastrointestinal cancers; however, further investigations into the roles of these folate metabolizing genes in the context of cancer palliative care, from clinical, biological and epidemiological viewpoints are warranted.

BACKGROUND: In palliative care, prediction of life expectancy is one of the most crucial issues for patients, family and medical staff, in order to provide appropriate end-of-life care. The aim of this study was to formulate a new objective score to predict life expectancy within 1 week for terminally ill patients with cancer. PATIENTS AND METHODS: Medical records were obtained from 187 terminally-ill patients with cancer who were admitted for palliative care. The biomarkers for a potential 'Objective Predictive Score' were assessed. RESULTS: Profiling of blood parameters demonstrated that elevated levels of alanine aminotransferase (ALT), total bilirubin (T-bil), blood urea nitrogen (BUN), creatinine (Cr) and a decreased platelet count were significantly correlated with death within 1 week in a training cohort. Our formulated Objective Predictive Score was able to predict death within 1 week with high accuracy in a training and a validation cohort. CONCLUSION: Our scoring system might enable the assessment of prognostication with higher accuracy in a terminal care setting.

Despite recent advances in chemotherapy for gastrointestinal cancer, a crucial factor related to poor prognosis is reduced tolerance to chemotherapy induced by cancer cachexia. Fish oil (FO)-derived eicosapentaenoic acid (EPA) modulates inflammation in patients with various malignancies; however, the impact of FO-enriched nutrition as a combined modality therapy on clinical outcomes remains controversial. We systemically analysed chronological changes in biochemical and physiological status using bioelectrical impedance analysis in 128 gastrointestinal cancer patients provided with or without FO-enriched nutrition during chemotherapy. Furthermore, we evaluated the clinical significance of FO-enriched nutrition and clarified appropriate patient groups that receive prognostic benefits from FO-enriched nutrition during treatment of gastrointestinal cancer. The control group showed significant up-regulation of serum CRP) levels and no significant difference in both skeletal muscle mass and lean body mass. In contrast, the FO-enriched nutrition group showed no changes in serum CRP concentration and significantly increased skeletal muscle mass and lean body mass over time. Furthermore, high CRP levels significantly correlated with reduced tolerance to chemotherapy, and FO-enriched nutrition improved chemotherapy tolerance and prognosis, particularly in gastrointestinal cancer patients with a modified Glasgow prognostic score (mGPS) of 1 or 2. We conclude that FO-enriched nutrition may improve the prognosis of patients with cancer cachexia and systemic inflammation (i.e., those with a mGPS of 1 or 2).

Serous borderline tumors and low-grade serous adenocarcinomas typically exhibit a low mitotic index and are largely resistant to chemotherapy. They are characterized by specific mutations, including mutations of KRAS and BRAF, which target specific cell signaling pathways. Mutational analyses may provide further insight into the development sequence of low-grade serous carcinomas. There are 3 methods to detect BRAF mutations: direct sequencing, such as Sanger sequencing (Sas); immunohistochemistry (IHC); and competitive allele-specific hydrolysis probe (TaqMan) PCR technology (CAST-PCR). In the present study, we matched the results of these 3 methods in ovarian serous borderline tumor cases. This study was carried out in 11 surgically removed ovarian serous borderline tumors. Detection of the BRAF V600E mutation was carried out by the FLEX detection system using the VE1 clone antibody and the results were compared with those of Sas and CAST-PCR. The autostainer IHC VE1 assay was positive in 3 of the 11 ovarian serous borderline tumors and negative in the remaining 8 tumors. CAST-PCR demonstrated a BRAF V600E mutation ratio of 16.4, 17.7 and 12.7%, respectively, in the 3 IHC-positive cases. Sas detected the BRAF V600E mutation in only 2 cases, while revealing wild-type BRAF in the remaining 9 cases. Sas revealed KRAS mutations in 2 of these 9 cases with wild-type BRAF. Our data suggest a high concordance rate of the results between CAST-PCR and IHC. Thus, IHC using the VE1 clone and FLEX linker is a specific method for the detection of BRAF V600E and may be an alternative to molecular-biologic techniques for the detection of mutations in ovarian serous borderline tumors. This method may be a useful screening method for the BRAF mutation.
