Long-term outcomes of the first prospective study of active surveillance for prostate cancer in Japan.

Background: Active surveillance for prostate cancer was initiated in the early 2000s. We assessed the long-term outcomes of active surveillance in Japan.

Methods: This multicenter prospective observational cohort study enrolled men aged 50-80 years with stage cT1cN0M0 prostate cancer in 2002 and 2003.

A phase II Japanese trial of 90-minute rituximab infusion for untreated B-cell lymphoma.

Objective: This phase II clinical trial evaluated feasibility and tolerability of 90-minute rituximab infusion and a concentration of 4 mg/mL rituximab infusion in Japanese patients with previously untreated follicular lymphoma or diffuse large B-cell lymphoma.

Methods: Treatment was rituximab with cyclophosphamide, doxorubicin, vincristine and prednisolone. In cycle 1, rituximab at a dose of 375 mg/m2 (4 mg/mL) was administered at the standard infusion rate stipulated in the package insert.

A prospective study of the relationship between CRPC patient's quality of life after enzalutamide and serum testosterone levels measured via LC-MS/MS.

Background: Enzalutamide (ENZ) is used in the treatment of patients with castration-resistant prostate cancer (CRPC). The quality of life (QoL) of CRPC patients during ENZ treatment is very important, but predictive markers of QoL have not been identified. We investigated the relationship between the serum testosterone (T) level before ENZ treatment and QoL changes in CRPC patients.

Early dynamics of chronic myeloid leukemia on nilotinib predicts deep molecular response.

Chronic myeloid leukemia (CML) is a myeloproliferative disorder caused by the BCR-ABL1 tyrosine kinase. Although ABL1-specific tyrosine kinase inhibitors (TKIs) including nilotinib have dramatically improved the prognosis of patients with CML, the TKI efficacy depends on the individual patient. In this work, we found that the patients with different nilotinib responses can be classified by using the estimated parameters of our simple dynamical model with two common laboratory findings.

Castleman disease and mimickers: Clinicopathological findings of atypical lymphoproliferative disorders associated with autoimmune disease.

Atypical lymphoproliferative disorders (LPDs) related with autoimmune disease (AID) show marked clinicopathological diversity, which are defined as three distinct clinicopathological subtypes such as those resembling Castleman disease (CD), atypical paracortical hyperplasia with lymphoid follicles (APHLF), and atypical lymphoplasmacytic and immunoblastic proliferation (ALPIB). We studied excisional biopsy specimens from 31 patients with atypical LPDs associated with systemic lupus erythematosus (SLE), rheumatoid arthritis (RA), and Sjögren syndrome (SjS). The lesions in these 31 cases were classified into 6 (19.

Combined Interstitial and Intracavitary High-Dose Rate Brachytherapy of Cervical Cancer.

High-dose-rate brachytherapy by remote afterloading is now performed under three-dimensional image guidance by CT or MRI. Three-dimensional image-guided brachytherapy in cervical cancer disclosed that the traditional intracavitary brachytherapy by Manchester method cannot deliver an adequate dose to the large tumor with resulting local recurrence. To improve the local control rate, combined interstitial and intracavitary (hybrid) brachytherapy can increase the dose to the large parametrial involvement without increasing the dose to the rectum and bladder.

Avelumab plus axitinib therapy for renal cell carcinoma in a patient with pulmonary alveolar proteinosis: A case report.

Pulmonary alveolar proteinosis (PAP) is a rare disease characterized by the abnormal accumulation of surfactant-derived substances in the lungs. To the best of our knowledge, the successful treatment of metastatic renal cell carcinoma in patients with PAP has not been reported. Here, we describe such treatment of a patient via avelumab plus axitinib therapy.

A Prospective Study of the Relationship Between Clinical Outcomes After Enzalutamide and Serum Androgen Levels Measured via Liquid Chromatography-tandem Mass Spectrometry in Patients with Castration-resistant Prostate Cancer.

Background: Enzalutamide (ENZ) is used to treat patients with castration-resistant prostate cancer (CRPC). However, the kinetics of serum androgens before and after ENZ treatment are unknown.

Objective: To elucidate the kinetics of serum androgens and explore the possibility of identifying a useful marker for predicting the effects of ENZ.

Patient-reported outcomes following neoadjuvant endocrine therapy, external beam radiation, and adjuvant continuous/intermittent endocrine therapy for locally advanced prostate cancer: A randomized phase III trial.

Background: We evaluated patient-reported outcomes (PRO) during neoadjuvant androgen deprivation therapy (ADT) plus external beam radiation therapy (EBRT) followed by either adjuvant continuous ADT (CADT) or intermittent ADT (IADT) for patients with locally advanced prostate cancer (Pca).

Methods: A multicenter, randomized phase III trial enrolled 303 patients with locally advanced Pca. The patients were treated with 6 months (M) of ADT followed by 72 Gy of EBRT, and were randomly assigned to CADT or IADT after 14 M.

DA-EPOCH-R combined with high-dose methotrexate in patients with newly diagnosed stage II-IV CD5-positive diffuse large B-cell lymphoma: a single-arm, open-label, phase II study.

CD5-positive diffuse large B-cell lymphoma (CD5+ DLBCL) is characterized by poor prognosis and a high frequency of central nervous system relapse after standard immunochemotherapy. We conducted a phase II study to investigate the efficacy and safety of dose-adjusted (DA)- EPOCH-R (etoposide, prednisone, vincristine, cyclophosphamide, doxorubicin, and rituximab) combined with high-dose methotrexate (HD-MTX) in newly diagnosed patients with CD5+ DLBCL. Previously untreated patients with stage II to IV CD5+ DLBCL according to the 2008 World Health Organization classification were eligible.

Oncological outcomes for patients with locally advanced prostate cancer treated with neoadjuvant endocrine and external-beam radiation therapy followed by adjuvant continuous/intermittent endocrine therapy in an open-label, randomized, phase 3 trial.

Background: To date, research has not determined the optimal procedure for adjuvant androgen deprivation therapy (ADT) in patients with locally advanced prostate cancer (PCa) treated for 6 months with neoadjuvant ADT and external-beam radiation therapy (EBRT).

Methods: A multicenter, randomized, phase 3 trial enrolled 303 patients with locally advanced PCa between 2001 and 2006. Participants were treated with neoadjuvant ADT for 6 months.

Optimal treatment strategy with nilotinib for patients with newly diagnosed chronic-phase chronic myeloid leukemia based on early achievement of deep molecular response (MR ): The phase 2, multicenter N-Road study.

For patients who have chronic myeloid leukemia (CML), one of the primary treatment options is administration of nilotinib 300 mg twice daily (BID). In previous studies which compared outcomes associated with nilotinib or imatinib treatment, nilotinib achieved a higher rate of deep molecular response (MR). We conducted a phase II, open-label, multicenter study to investigate an intrapatient nilotinib dose-escalation strategy for patients with newly diagnosed chronic-phase (CP) CML based on early MR achievement.

A phase I and extension study of S-1 and carboplatin for previously untreated patients aged 75 years or more with advanced non-small cell lung cancer -TCOG 1101.

Purpose: Combination carboplatin and S-1 is active in the treatment of non-small cell lung cancer (NSCLC). However, data on this combination for elderly patients with NSCLC are insufficient.

Methods: Eligibility criteria were no prior chemotherapy, Stage IIIB or IV NSCLC, performance status 0-1, age ≥ 75 years, and adequate hematological, hepatic, and renal functions.

[CLINICAL OUTCOMES OF ABIRATERONE ACETATE FOR TREATMENT OF CASTRATION-RESISTANT PROSTATE CANCER: A RETROSPECTIVE ANALYSIS].

(Objective) We retrospectively evaluated the clinical efficacy and safety of abiraterone acetate (AA) in patients with castration-resistant prostate cancer (CRPC). (Methods) We analyzed the clinical records of 50 patients who had received AA in Gunma Cancer Center between October 2014 and June 2017. We assessed the response of prostate-specific antigen (PSA) to AA, and analyzed the association between overall survival and various parameters, including the types of primary hormonal therapy, PSA level, Gleason score, time to CRPC, prior treatment with enzalutamide (Enz) and docetaxel, and sites of metastases.

Plerixafor for mobilization and collection of haematopoietic stem cells for autologous transplantation in Japanese patients with non-Hodgkin lymphoma: a randomized phase 2 study.

The present study (ClinicalTrials.gov Identifier: NCT02221492) was conducted to assess the efficacy and safety of plerixafor for the mobilization and collection of haematopoietic stem cells (HSCs) for autologous transplantation in Japanese non-Hodgkin lymphoma (NHL) patients. In this randomized phase 2 study, patients received granulocyte-colony stimulating factor (G-CSF, filgrastim) 400 µg/m²/day for up to 8 days.

Bortezomib maintenance therapy in transplant-ineligible myeloma patients who plateaued after bortezomib-based induction therapy: a multicenter phase II clinical trial.

In the era of novel therapeutic agents for multiple myeloma (MM), both the significance of achieving the plateau phase and the efficacy of subsequent maintenance therapy remain unclear. In the present study, we evaluated the efficacy and safety of bortezomib maintenance therapy (biweekly for 1 year) in transplant-ineligible MM patients who plateaued after bortezomib-based induction therapy. Of 36 evaluable patients, the overall response rate during induction therapy was 61%, with a stringent complete response in 6%, a complete response in 6%, a very good partial response in 17%, and a partial response in 33%.

Differences in heart rate variability may be related to the appearance of postoperative pain in patients undergoing breast cancer surgery.

Background: Some reports have highlighted the relationship between heart rate variability (HRV) and the degree of postoperative pain experienced. This study retrospectively examined whether differences in heart rate variability may be related to the appearance of postoperative pain in patients undergoing breast cancer surgery.

Findings: We retrospectively analyzed 20 postoperative patients who had no pain immediately upon admission to the post-anesthesia care unit (PACU), divided into two groups: group A ( = 16) had no pain on admission to PACU, remaining pain free upon discharge (12 h after surgery); group B ( = 4) comprised patients with no pain on admission to PACU but who experienced increasing pain requiring intervention in PACU 1 h after surgery.

Clinical management and outcomes of completely resected stage I follicular lymphoma.

Recent studies have revealed the clinical and biological features of stage I follicular lymphoma (FL), but information about patients with stage I FL who underwent total resection after tissue biopsy is limited. Among 305 FL patients diagnosed between 2001 and 2013, clinical stage I disease was observed in 36 patients. Of these, 18 patients underwent total resection after diagnostic tissue biopsy.

Effect of Low Dose Remifentanil on Postoperative Pain Relief and Heart Rate Variability in Post-Anaesthesia Care Unit.

Objective: Several reports have shown the negligible adverse effects of low-dose remifentanil on the autonomic nervous system. We propose that the administration of low-dose remifentanil would be beneficial without adverse respiratory and hemodynamic effects. This study aimed to examine the effects of low-dose remifentanil on postoperative pain relief and heart rate variability (HRV) after surgery.

Randomized phase II study of a bendamustine monotherapy schedule for relapsed or refractory low-grade B-cell non-Hodgkin lymphoma or mantle cell lymphoma (RABBIT-14).

The aim of this randomized phase II study was to improve the treatment delays and discontinuations associated with bendamustine use by comparing the effect of Benda-14 (intravenous bendamustine, 120 mg/m on days 1 and 15, repeated every 4 weeks for a total of 6 cycles) with those of the standard treatment in relapsed indolent lymphoma and/or mantle cell lymphoma. Forty-six patients were randomly assigned to the treatments from September 2012 to February 2016. Treatment accomplishment rate and median relative dose intensity were similar in both arms: 38 and 63.

Retrospective analysis of prognostic factors for Waldenstrӧm macroglobulinemia: a multicenter cooperative study in Japan.

Although population-based cancer registries have reported lower incidence of Waldenstrӧm macroglobulinemia (WM) in East Asia than in Western countries, previous retrospective analyses have found the clinical features of WM to be similar in these two populations. To clarify the characteristics of Japanese WM patients, we retrospectively analyzed clinical and laboratory characteristics, treatments, outcomes, and prognostic factors in 93 patients with WM. Based on the Second International Workshop on WM (IWWM-2) criteria, symptomatic WM was found in 73 (78.
