OBJECTIVE The purpose of this study was to evaluate whether preoperative measurements of the minimum apparent diffusion coefficient (ADCmin) on magnetic resonance imaging (MRI) and the tumor marker CA125 are correlated with the clinical characteristics and prognosis of patients with endometrial cancer. METHODS The distribution of cases that scored positive for each of the biological parameters examined and the correlations with the ADCmin of the primary tumor and the serum tumor marker CA125 were examined for 111 patients with preoperative assessment of primary endometrial cancer. RESULTS There were significant correlations between the ADCmin of the primary tumor and the FIGO stage (P=0.001), depth of myometrial invasion (P<0.001), cervical involvement (P=0.003), lymph node metastasis (P=0.027), ovarian metastasis (P<0.001), peritoneal cytology (P=0.027) and tumor maximum size (P<0.001). The disease-free survival (DFS) rate of patients with high serum CA125 was significantly lower than that of patients with low serum CA125 (P=0.0395). The DFS rate of patients with a low ADCmin of the primary tumor was significantly lower than that of patients with a high ADCmin of the primary tumor (P<0.001). In particular, the ADCmin of the primary tumor was an independent factor for disease recurrence in a multivariate analysis (P=0.019). CONCLUSIONS The present findings indicate that a low preoperative ADCmin of the primary tumor is an important predictive factor for identifying endometrial cancer patients with a risk of disease recurrence.

Inflammation and tumor immunology are associated with prognosis in a variety of cancers. The aim of the present retrospective study was to identify associations between the neutrophil to lymphocyte ratio (NLR), platelet to lymphocyte ratio (PLR), cancer antigen 125 (CA125) concentrations, tumor response, performance status (PS) and survival of patients that developed recurrent ovarian cancer subsequent to receiving chemotherapy. The NLR and PLR measured prior to fourth-line chemotherapy were significantly increased compared with those measured prior to second-line chemotherapy (P=0.029 and 0.049, respectively). By using receiver operating characteristic curves, the cut-off values were determined for the NLR, PLR and CA125 levels that were measured during the pre-treatment phase, which predicted the outcomes. According to univariate analyses, pre-treatment NLR >3.91, PLR >299.0 and PS 2 were each significantly associated with poor outcomes (P=0.001, 0.005 and 0.021, respectively). According to multivariate analyses, only pre-treatment NLR was associated with poor outcome (P=0.035). The present findings indicate that pre-treatment NLR is an important predictor of prognosis in patients with ovarian cancer that experience recurrence following chemotherapy.

Abstract:  Prostatic basal cell carcinoma (BCC), a distinctive variant of adenocarcinoma, is rare. We report a patient with pure basaloid BCC showing an extraprostatic extension and lymph node metastases. A 67‐year‐old man with urinary outlet obstruction was referred to our hospital. Digital rectal examination disclosed a stony hard prostate. Serum prostate‐specific antigen and prostatic acid phosphatase were within the normal range. Transrectal needle biopsy of the prostate was followed by transurethral resection as symptomatic treatment. The lesion was diagnosed histopathologically as BCC. Despite antiandrogen therapy distant metastases developed, and the patient died 5 months postoperatively. We discuss the histological and immunohistochemical findings in this case.

Background The molecular characterization of endometrial cancer (EC) can facilitate identification of various tumor subtypes. Although EC patients with POLE mutations reproducibly demonstrate better prognosis, the outcome of patients with microsatellite instability (MSI) remains controversial. This study attempted to interrogate whether genetic stratification of EC can identify distinct subsets with prognostic significance. Materials and methods A cohort of 138 EC patients who underwent surgical resection with curative intent was enrolled. Sanger sequencing was used to evaluate mutations in the POLE and KRAS genes. MSI analysis was performed using four mononucleotide repeat markers and methylation status of the MLH1 promoter was measured by a fluorescent bisulfite polymerase chain reaction (PCR). Protein expression for mismatch repair (MMR) proteins was evaluated by immunohistochemistry (IHC). Results Extensive hypermethylation of the MLH1 promoter was observed in 69.6% ECs with MLH1 deficiency and 3.5% with MMR proficiency, but in none of the ECs with loss of other MMR genes (P < .0001). MSI-positive and POLE mutations were found in 29.0% and 8.7% EC patients, respectively. Our MSI analysis showed a sensitivity of 92.7% for EC patients with MMR deficiency, and a specificity of 97.9% for EC patients with MMR proficiency. In univariate and multivariate analyses, POLE mutations and MSI status was significantly associated with progression-free survival (P = 0.0129 and 0.0064, respectively) but not with endometrial cancer-specific survival. Conclusions This study provides significant evidence that analyses of proofreading POLE mutations and MSI status based on mononucleotide repeat markers are potentially useful biomarkers to identify EC patients with better prognosis.

Objective This study aimed to investigate the correlation of sarcopenia findings with prognostic factors in patients with cervical cancer (CC) undergoing concurrent chemoradiotherapy (CCRT). Methods We retrospectively collected data on body composition and clinicopathological features from the medical records of 60 patients with CC who underwent CCRT and analyzed correlations between prognosis and changes in body composition as measured by computed tomography (skeletal muscle and iliopsoas muscle [IM]). Statistical analyses were performed using the Mann-Whitney U test. Progression-free survival (PFS) and overall survival (OS) were analyzed using the Kaplan-Meier method. Cox proportional hazard regression was used for univariate and multivariate analyses. Results The median follow-up for all patients who were alive at the last follow-up was 33.5 months (range, 1–104 months). The PFS and OS rates were worse for patients with at least 15.0% than for those with less than 15.0% loss of skeletal muscle and IM from baseline (P < 0.001 for both). Furthermore, multivariate analyses showed that at least 15.0% loss of IM was an independent prognostic factor for PFS and OS (P = 0.002 for both). Conclusions Sarcopenia (≥15.0% loss of IM from baseline) was revealed to be an important prognostic factor in patients with CC undergoing CCRT.

Objective The Glasgow prognostic score (GPS) determined at pretreatment is important in the prediction of prognosis in various cancers. We investigated if the GPS used both at pretreatment and during concurrent chemoradiotherapy (CCRT) could predict the prognosis of patients with cervical cancer. Methods We collected GPS and clinicopathological data from the medical records of 91 patients who underwent CCRT for cervical cancer; their GPSs at pretreatment and during CCRT were retrospectively analyzed for correlations with recurrence and survival. Statistical analyses were performed using the Mann-Whitney U test. Disease-free survival (DFS) and overall survival (OS) were analyzed using the Kaplan-Meier method. Cox’s proportional hazard regression was used for univariate and multivariate analyses. Results The median follow-up for all patients who were alive at the time of last follow-up was 38.0 months (range, 1–108 months). The DFS and OS rates of patients with a high GPS during CCRT (GPS 1 + 2; 55 patients; 60.4%) were significantly shorter than those for patients with a low GPS (GPS 0; 36 patients; 39.6%) (DFS, P < 0.001; OS, P < 0.001). Furthermore, multivariate analyses showed that high GPS during CCRT was an independent prognostic factor of survival for OS (P = 0.008). Conclusions During CCRT, a high GPS was revealed to be an important predictor of survival for cervical cancer.

Abstract Umbilical arteriovenous malformation (AVM) is a rare congenital malformation. We report a case of umbilical AVM that was prenatally diagnosed by further color Doppler ultrasonography because of fetal cardiomegaly. At 35 weeks gestation, a male newborn was delivered by emergent cesarean section because of rapid progress of cardiomegaly and breech presentation. Three-dimensional reconstructed computed tomography after birth demonstrated the shunt was spontaneously closed. This is the first case report of umbilical AVM, which was prenatally diagnosed, and the boy was successfully delivered, suggesting that, when fetal cardiomegaly is identified, umbilical AVM must be taken into consideration.

Objective The objective of this observational study was to investigate correlations between adverse effects (lower-extremity lymphedema [LEL], dysuria, and severe gastrointestinal symptoms) and quality of life (QOL) (physical well-being [PWB], social well-being, emotional well-being [EWB], and functional well-being) before treatment, at least 6 weeks after treatment (posttreatment1), and 3 or 6 months after treatment (posttreatment2) of patients with gynecologic cancer (GC). Methods From August 2012 to October 2016, questionnaire responses and clinical data of 75 patients with GC were collected and assessed by treatment received. The χ2 test was used to determine the significance of correlations. Results Participants with LEL had significantly poorer QOL than did those without it in the domains of PWB at posttreatment1 (P = 0.026) and EWB at posttreatment2 (P = 0.020). Moreover, patients with 2 adverse effects (LEL plus dysuria or severe gastrointestinal symptoms) had significantly poorer QOL than did those with no or single adverse effect in the domains of PWB at posttreatment1 and posttreatment2 (posttreatment1: P = 0.049, P = 0.001; posttreatment2: P = 0.002, P = 0.028) and poorer QOL compared with those with no adverse effect in the domain of EWB at posttreatment1 (P = 0.017). Conclusions Poorer QOL in emotional and physical domains is associated with adverse effects of treatment in patients with GC. It is important to consider the effects of radical therapy not only on survival but also on the QOL of survivors.
