BACKGROUND: The salvage treatments for biochemical recurrence (BCR) include local external beam radiation therapy (RT) and systemic androgen-deprivation therapy (ADT). METHODS: We reviewed patients who underwent radical prostatectomy (RP) and developed BCR at three institutions. After excluding patients whose nadir prostate-specific antigen (PSA) was higher than 0.2 ng/mL, those who received neoadjuvant/adjuvant therapy, and those whose BCR was not treated until their PSA exceeded 4.0 ng/mL, the remaining 335 patients comprised the cohort of this study. Salvage RT and ADT were performed for 154 and 181 patients, respectively. After the failure of salvage RT, all patients received subsequent ADT. The starting point of this study was the timing of BCR and the endpoint was the development of castration-resistant prostate cancer (CRPC). RESULTS: During the mean follow-up period of 8.5 years after BCR, CRPC was observed in 13 patients administered RT and 24 patients administered ADT. Kaplan-Meier curves demonstrated no significant difference in CRPC-free survival between the RT and ADT groups (10-year CRPC-free survival 89.9 vs. 86.3%, p = 0.199). On the other hand, we found a significant difference in CRPC-free survival between the RT and ADT groups in 50 high-risk patients with two risk factors of Grade Group ≥ 4 and PSA-doubling time < 6 months (10-year CRPC-free survival 73.4 vs. 40.3%, p = 0.040). CONCLUSION: This study revealed that salvage RT increases the CRPC-free survival rate compared with salvage ADT in high-risk patients with Grade Group ≥ 4 and PSA-doubling time < 6 months.

Introduction: Most metastatic prostate cancers acquire the capacity for androgen-independent growth and become resistant to androgen deprivation therapy. A patient-focused treatment strategy is needed for aggressive castration-resistant prostate cancer. Case presentation: We report the case of a 62-year-old man who presented with prostatic adenocarcinoma who was treated by radiation and combined androgen blockade. After completion of first-line therapy, he was diagnosed with multiple metastatic castration-resistant prostate cancer in the lung. Second-line therapy with abiraterone acetate resulted in partial remission of the lung metastases. Thoracic surgery was performed to remove the single lung metastasis remaining. Next-generation sequencing of the specimens demonstrated homozygous loss of BRCA2. We note in this case a heterogeneous response to abiraterone acetate may be related to the somatic BRCA2 deletions. Conclusions: We present the first Japanese case of a metastatic abiraterone acetate-resistant castration-resistant prostate cancer accompanied by BRCA2 mutation.

Transient hypercalcemia in a patient with SAPHO syndrome

Yoshida T., Oya M.

Journal of General and Family Medicine (Journal of General and Family Medicine) 23 ( 1 ) 44 - 46 2021

ISSN 2189-7948

We here report a case of SAPHO (synovitis-acne-pustulosis-hyperostosis-osteitis) syndrome with hypercalcemia. The patient was diagnosed with SAPHO syndrome at the age of 54, because he exhibited osteitis and hyperostosis around the sternoclavicular joints and the temporomandibular joints bilaterally and had past medical history of palmoplantar pustulosis. At the age of 67, he exhibited appetite loss and nausea. Corrected serum calcium was 13.0 mg/dl. Adequate hydration was recommended, and his calcium levels returned to the normal range without any medical treatment. Although speculative, his hypercalcemia was considered to be caused by an increased bone activity in SAPHO syndrome. This is the first report describing transient hypercalcemia in a patient with SAPHO syndrome.

Background: Patients with anti-melanoma differentiation-associated gene 5 (MDA5) antibody-positive dermatomyositis (DM) are frequently accompanied by rapidly progressive-interstitial lung disease (RP-ILD). They are often refractory to intensive immunosuppressive therapy and have poor prognosis. Case presentation: A 73-year-old woman presented with fever, cold symptoms, and skin eruption for a month. She also exhibited muscle weakness on upper extremities slightly. The titer of anti-MDA5 antibody was extremely high, and computed tomography showed ground glass opacity and reticular shadows in the lungs. She was diagnosed as anti-MDA5 antibody-positive classical DM-associated RP-ILD and treated with intensive immunosuppressive therapy. However, the titer of anti-MDA5 antibody did not decrease satisfactorily, and plasma exchange was alternatively initiated. The titer decreased remarkably, and she obtained disease remission. Similarly, a 63-year-old woman presented with stiffness of the neck and hands, fever and cough. She was also diagnosed as anti-MDA5 antibody-positive classical DM-associated RP-ILD, because she had skin eruptions, slight muscle weakness, an elevation in anti-MDA5 antibody, and RP-ILD. She was unresponsive to intensive immunosuppressive therapy, but plasma exchange successfully improved the titer of anti-MDA5 antibody, the symptoms, and the findings of computed tomography. Conclusions: Although anti-MDA5 antibody-positive DM-associated RP-ILD has a high mortality rate, this report suggests the usefulness of plasma exchange to improve the prognosis.

A 61-year-old woman with a 4-year history of maintenance hemodialysis due to end-stage renal disease of unknown cause was admitted because of a recurrent fever and abdominal pain lasting for 3 months. She had rheumatoid arthritis as a complication and had taken sulfasalazine for over 4 years. Laboratory data revealed thrombocytopenia, hypocomplementemia, a high C-reactive protein level, and positivity for antinuclear antibody and anti-double strand DNA antibody. Gallium scintigraphy showed pericarditis, pleuritis, and peritonitis. Nonscarring alopecia was also noted. She was diagnosed as having systemic lupus erythematosus (SLE). Drug-induced lupus elicited by sulfasalazine was ruled out because the symptoms did not improve even after the discontinuation of the drug upon admission. Oral prednisolone treatment markedly improved her symptoms and laboratory data. However, she later died of sepsis arising from proctitis on day 71 of admission. This report underscores the necessity of considering new-onset SLE in patients with unexplained fever and serositis, including pleuritis, peritonitis, or pericarditis, even if they are receiving maintenance dialysis.

The Brg/Brahma-associated factor (BAF, mSWI/SNF) chromatin remodeling complex is of importance in development and has been linked to prostate oncogenesis. The oncogenic MUC1-C protein promotes lineage plasticity in the progression of neuroendocrine prostate cancer (NEPC), however, there is no known association between MUC1-C and BAF. We report here that MUC1-C binds directly to the E2F1 transcription factor and that the MUC1-C→E2F1 pathway induces expression of embryonic stem cell-specific BAF (esBAF) components BRG1, ARID1A, BAF60a, BAF155, and BAF170 in castrate-resistant prostate cancer (CRPC) and NEPC cells. In concert with this previously unrecognized pathway, MUC1 was associated with increased expression of E2F1 and esBAF components in NEPC tumors as compared with CRPC, supporting involvement of MUC1-C in activating the E2F1→esBAF pathway with progression to NEPC. MUC1-C formed a nuclear complex with BAF and activated cancer stem cell (CSC) gene signatures and the core pluripotency factor gene network. The MUC1-C→E2F1→BAF pathway was necessary for induction of both the NOTCH1 effector of CSC function and the NANOG pluripotency factor, and collectively, this network drove CSC self-renewal. These findings indicate that MUC1-C promotes NEPC progression by integrating activation of E2F1 and esBAF with induction of NOTCH1, NANOG, and stemness. SIGNIFICANCE: These findings show that MUC1-C, which promotes prostate cancer progression, activates a novel pathway that drives the BAF remodeling complex, induces NOTCH1 and NANOG, and promotes self-renewal of prostate cancer stem cells.

BACKGROUND: Darolutamide, an oral androgen receptor inhibitor, has been approved for treating nonmetastatic castration-resistant prostate cancer (nmCRPC), based on significant improvements in metastasis-free survival (MFS) in the ARAMIS clinical trial. Efficacy and safety of darolutamide in Japanese patients are reported here. METHODS: In this randomized, double-blind, placebo-controlled phase III trial, 1509 patients with nmCRPC and prostate-specific antigen (PSA) doubling time ≤ 10 months were randomized 2:1 to darolutamide 600 mg twice daily or matched placebo while continuing androgen deprivation therapy. The primary endpoint was MFS. RESULTS: In Japan, 95 patients were enrolled and randomized to darolutamide (n = 62) or placebo (n = 33). At the primary analysis (cut-off date: September 3, 2018), after 20 primary end-point events had occurred, median MFS was not reached with darolutamide vs. 18.2 months with placebo (HR 0.28, 95% CI 0.11-0.70). Median OS was not reached due to limited numbers of events in both groups but favored darolutamide in the Japanese subgroup. Time to pain progression, time to PSA progression, and PSA response also favored darolutamide. Among Japanese patients randomized to darolutamide vs. placebo, incidences of treatment-emergent adverse events (TEAEs) were 85.5 vs. 63.6%, and incidences of treatment discontinuation due to TEAEs were 8.1 vs. 6.1%. CONCLUSIONS: Efficacy outcomes favored darolutamide in Japanese patients with nmCRPC, supporting the clinical benefit of darolutamide in this patient population. Darolutamide was well tolerated; however, due to the small sample size, it is impossible to conclude with certainty whether differences in the safety profile exist between Japanese and overall ARAMIS populations.

Because end-stage renal disease patients undergoing hemodialysis frequently take acid suppressants for the treatment or prevention of gastrointestinal diseases, it is important to clarify the drug-interactions between acid suppressants and phosphate binders on the control of serum phosphate levels. In the present study, we examined whether the phosphate-lowering effects of three phosphate binders, lanthanum carbonate (LC), ferric citrate hydrate (FCH), and sucroferric oxyhydroxide (SFOH), were affected by proton pump inhibitors (PPIs) in maintenance hemodialysis patients. Laboratory data for 71 patients who had been newly prescribed one of the three phosphate binders were examined. LC at a dosage of 500 ± 217 mg/day significantly decreased serum phosphate levels by -18% in the absence of a PPI (n = 9), while a dosage of 700 ± 230 mg/day only decreased it by -3% in the presence of a PPI (n = 10). Thus, the efficacy of LC in reducing serum phosphate levels was significantly hindered by the presence of PPIs. FCH significantly decreased serum phosphate levels by -18% in the absence of a PPI (n = 7, FCH: 571 ± 189 mg/day) and by -17% in the presence of a PPI (n = 20, FCH: 638 ± 151 mg/day). The decrease in serum phosphate levels by SFOH (393 ± 197 mg/day) was -7% in the absence of a PPI (n = 7), and SFOH at a dosage of 556 ± 316 mg/day significantly decreased serum phosphate levels by -13% in the presence of a PPI (n = 18). These results suggest that the phosphate-lowering effect of LC, but not of FCH or SFOH, is diminished in the presence of PPIs in hemodialysis patients.

OBJECTIVES: In our multicenter study evaluating metastatic papillary renal cell carcinoma (PRCC), 29% of tumors diagnosed as PRCC in collaborative institutes were finally diagnosed as other RCCs under central review. In those tumors, mucinous tubular and spindle cell carcinoma (MTSCC) was the leading histology, followed by unclassified RCC (ucRCC). We focused on those patients with MTSCC or ucRCC. METHODS: We reviewed the processes for the pathological diagnoses of nine tumors and reviewed their clinical features. RESULTS: All of the MTSCCs and ucRCCs were positive for AMACR, which is frequently positive in PRCC. Mucin was demonstrated in 80% of the MTSCCs, and its presence is important for their diagnoses. One MTSCC was diagnosed as a mucin-poor variant. The presence of spindle cells with low-grade nuclei was suggestive of MTSCC, but the diagnosis of high-grade MTSCC was difficult. Four tumors were diagnosed as ucRCC by histological and immunohistochemical findings. Three of the four tumors were suspicious of ucRCC in the initial review due to atypical findings as PRCC. Sunitinib and interferon-α were effective for one MTSCC patient who survived for >5 years. Two MTSCC patients who were Memorial Sloan-Kettering Cancer Center poor risk had unfavorable prognoses. One patient with mucin-poor MTSCC had an indolent clinical course. Two of four ucRCC patients showed durable stable disease with targeted agents (TAs) and survived >3 years. CONCLUSION: Some MTSCC metastases progressed very slowly and poor-risk tumors progressed rapidly. Systemic therapies including TAs showed some efficacies. Some patients who have metastatic ucRCC with microscopic papillary architecture can benefit from TAs.

Cyclin-dependent kinase 12 (CDK12), one of the key factors associated with DNA damage response pathways, is located on chromosome 17 proximal to Erb-B2 receptor tyrosine kinase 2 (ERBB2). In this report, CDK12 and ERBB2 coamplification was detected by targeted next-generation sequencing in two urothelial carcinomas. The staining intensity of the CDK12 and human epidermal growth factor receptor-2 proteins was associated with the prognosis of each urothelial carcinoma case. Our results suggest that CDK12 coamplification with ERBB2 might be associated with tumor aggressiveness and contribution to cancer pathogenesis. Therapies targeting CDK12 should be developed for these patients.
