Objective:
To evaluate the long-term efficacy and safety of niraparib in Japanese women with heavily pretreated ovarian cancer.
Methods:
This was the follow-up analysis of a phase 2, multicenter, open-label, single-arm study in Japanese women with homologous recombination-deficient, platinum-sensitive, relapsed, high-grade serous epithelial ovarian, fallopian tube, or primary peritoneal cancer who had completed 3–4 lines of chemotherapy and were poly(ADP-ribose) polymerase inhibitor naïve. Participants received niraparib (starting dose, 300 mg) once daily in continuous 28-day cycles until objective disease progression, unacceptable toxicity, or consent withdrawal. The primary endpoint was confirmed objective response rate (ORR), as assessed using Response Evaluation Criteria in Solid Tumors version 1.1. Safety evaluations included treatment-emergent adverse events (TEAEs).
Results:
20 patients were enrolled in the study and included in both efficacy and safety analyses. Median total study duration was 759.5 days. Median dose intensity was 201.3 mg/ day. Confirmed ORR was 60.0% (90% confidence interval [CI]=39.4–78.3); 2 patients had complete response and 10 patients had partial response. Median duration of response was 9.9 months (95% CI=3.9–26.9) and the disease control rate was 90.0% (95% CI=68.3–98.8).The most common TEAEs were anemia (n=15), nausea (n=12), and decreased platelet count (n=11). TEAEs leading to study drug dose reduction, interruption, or discontinuation were reported in 16 (80.0%), 15 (75.0%), and 2 patients (10.0%), respectively.
Conclusion
The long-term efficacy and safety profile of niraparib was consistent with previous findings in the equivalent population in non-Japanese patients. No new safety signals were identified.

In this study, we aimed to clarify awareness regarding genetic testing among pharmacists in Hiroshima City to contribute to regional medical care provided in pharmacies. Pharmacists should consider the advantages and disadvantages of being able to easily receive genetic tests. We conducted an awareness survey on genetic testing among pharmacists belonging to the Hiroshima Pharmaceutical Association, at 645 pharmacies in Hiroshima City. Responses were received from 674 pharmacists, yielding a response rate of 43.4% (280 pharmacies). In response to the question, “Can you perform genetic testing at a pharmacy?”, 6.7% of pharmacists answered yes and 65.4% said this was impossible. Among the 92.4% of pharmacists other than those available, 79.6% answered “I am worried about my knowledge of genetic testing,” followed by 39.3% “cannot take the time,” 29.2% “hurdles for new business,” 28.1% “problems such as pharmacy facilities to protect personal information,” and 15.7% “ethical difficulties.” From the age difference, pharmacists do not carry out genetic testing even if they have knowledge; they need to make an ethical judgment to determine whether to conduct genetic testing. Additionally, although pharmacies provide medication guidance and protect personal information, 28.1% of pharmacists answered that there are problems with their pharmacy’s ability to protect personal information when handling “genetic information.” Pharmacists should consider it critical to treat “genetic information” as personal information, with the utmost care and understanding.

Journal of Gynecologic Oncology 2021;32(1):e9-
Objective:
The standard dose for pegylated liposomal doxorubicin (PLD) is 50 mg/m2 every 4 weeks. While 40 mg/m2 has recently been used in clinical practice, evidence supporting this use remains lacking.
Methods:
This phase III randomized, non-inferiority study compared progressionfree survival (PFS) for patients with platinum-resistant ovarian carcinoma between an experimental arm (40 mg/m2 PLD) and a standard arm (50 mg/m2 PLD) until 10 courses, disease progression or unacceptable toxicity. Eligible patients had received ≤2 prior lines.Stratification was by performance status and PFS of prior chemotherapy (<3 months versus ≥3 months). The primary endpoint was PFS and secondary endpoints were overall survival (OS), toxicity profile, clinical response and tolerability. The total number of patients was 470.
Results:
The trial was prematurely closed due to slow recruitment, with 272 patients randomized to the experimental arm (n=137) and standard arm (n=135). Final analysis was performed with 234 deaths and 269 events for PFS. In the experimental arm vs. standard arm, median PFS was 4.0 months vs. 4.0 months (hazard ratio [HR]=1.065; 95% confidence interval [CI]=0.830–1.366) and median OS was 14.0 months vs. 14.0 months (HR=1.078; 95% CI=0.831–1.397). Hematologic toxicity and oral cavity mucositis (≥grade 2) were more frequent in the standard arm than in the experimental arm, but no difference was seen in ≥grade 2 hand-foot skin reaction.
Conclusion
Non-inferiority of 2 PLD dosing schedule was not confirmed because the trial was closed prematurely. However, recommendation of dose reduction of PLD should be based both on efficacy and safety.

Journal of Gynecologic Oncology 2021;32(2):e16-
Objective:
To evaluate the efficacy and safety of niraparib in Japanese women with heavily pretreated ovarian cancer.
Methods:
This Phase 2 open-label, single-arm study enrolled Japanese women with homologous recombination deficiency-positive relapsed, high-grade serous ovarian, fallopian tube, or primary peritoneal cancer who had completed 3–4 lines of therapy. The starting dose of niraparib was 300 mg administered once daily in continuous 28-day cycles until objective progressive disease, unacceptable toxicity, consent withdrawal or discontinuation. The primary endpoint, objective response rate (ORR), was assessed by the investigator using RECIST version 1.1. Safety evaluations included the incidence of treatment-emergent adverse events (TEAEs), including serious TEAEs.
Results:
Twenty women were enrolled and the confirmed ORR in the full analysis set (FAS) was 35.0% (7/20), consisting of 1 complete response and 6 partial responses. Disease control rate in the FAS was 90.0%. The most frequently reported TEAEs (>50%) were anemia, nausea, and platelet count decreased. One patient (5.0%) had TEAEs leading to discontinuation of niraparib whereas reductions or interruptions were reported in 14 (70.0%) and 15 (75.0%) patients, respectively. The median dose intensity (202.9 mg daily) corresponded to a relative dose intensity of 67.6%.
Conclusion
Efficacy and safety of niraparib in heavily pretreated Japanese women was comparable to that seen in an equivalent population of non-Japanese women. No new safety signals were identified.

Objective:
In this study we sought to investigate the clinical factors that affect postprogression survival (PPS) in patients with recurrent or persistent clear cell carcinoma (CCC).We utilized the JGOG3017/Gynecological Cancer InterGroup data to compare paclitaxel plus carboplatin (TC) and irinotecan plus cisplatin (CPT-P) in the treatment of stages I to IV CCC.
Methods:
We enrolled 166 patients with recurrent or persistent CCC and assessed the impact of variables, including platinum sensitivity, treatment arm, crossover chemotherapy, primary stage, residual tumor at primary surgery, performance status, ethnicity, and tumor reduction surgery at recurrence on the median of PPS in patients with recurrent or persistent CCC.
Results:
A total of 77 patients received TC, and 89 patients received CPT-P. The median PPS for patients with platinum-resistant disease was 10.9 months, compared with 18.8 months for patients with platinum-sensitive disease (hazard ratio [HR]=1.88; 95% confidence interval [CI]=1.30–2.72; log-rank p<0.001). In the multivariate analysis, the platinum sensitivity (resistant vs. sensitivity; HR=1.60; p=0.027) and primary stage (p=0.009) were identified as independent predictors of prognosis factors for PPS in recurrent or persistent CCC.
Conclusions
Our findings revealed that platinum sensitivity and primary stage are clinical factors that significantly affect PPS in patients with recurrent or persistent CCC as wellas other histologic subtypes of ovarian cancer. PPS in patients with recurrent CCC should establish the basis for future clinical trials in this population.

OBJECTIVE: To examine the surgical-pathological predictors of para-aortic lymph node (PAN) metastasis at radical hysterectomy, and for PAN recurrence among women who did not undergo PAN dissection at radical hysterectomy. METHODS: This is a retrospective analysis of a nation-wide cohort study of surgically-treated stage IB–IIB cervical cancer (n=5,620). Multivariate models were used to identify independent surgical-pathological predictors for PAN metastasis/recurrence. RESULTS: There were 120 (2.1%) cases of PAN metastasis at surgery with parametrial involvement (adjusted odds ratio [aOR]=1.65), deep stromal invasion (aOR=2.61), ovarian metastasis (aOR=3.10), and pelvic nodal metastasis (single-node aOR=5.39 and multiple-node aOR=33.5, respectively) being independent risk factors (all, p<0.05). Without any risk factors, the incidence of PAN metastasis was 0.9%, while women exhibiting certain risk factor patterns (>20% of the study population) had PAN metastasis incidences of ≥4%. Among 4,663 clinically PAN-negative cases at surgery, PAN recurrence was seen in 195 (4.2%) cases that was significantly higher than histologically PAN-negative cases (2.5%, p=0.046). In clinically PAN-negative cases, parametrial involvement (adjusted hazard ratio [aHR]=1.67), lympho-vascular space invasion (aHR=1.95), ovarian metastasis (aHR=2.60), and pelvic lymph node metastasis (single-node aHR=2.49 and multiple-node aHR=8.11, respectively) were independently associated with increased risk of PAN recurrence (all, p<0.05). Without any risk factors, 5-year PAN recurrence risk was 0.8%; however, women demonstrating certain risk factor patterns (>15% of the clinically PAN-negative population) had 5-year PAN recurrence risks being ≥8%. CONCLUSION: Surgical-pathological risk factors proposed in this study will be useful to identify women with increased risk of PAN metastasis/recurrence.

We report on a rare case of Marfan syndrome with giant dissecting descending thoracic and abdominal aortic aneurysms associated with poor left ventricular function and severe mitral regurgitation. Before the anesthetic induction, a partial extra-corporeal circulation was established to prevent a collapse of the circulation. Descending aortic graft replacement and following abdominal aortic graft replacement were performed safely using the partial extra-corporeal circulation to relief the afterload for the severely deteriorated left ventricle with severe mitral regurgitation. Intra-aortic balloon pumping was also promptly used to assist the poor circulation in the postoperative period. Despite the admission to a specialized institute, he died from irreversible heart failure with a developing renal failure. Even for a difficult patient with Marfan syndrome with severe left ventricular dysfunction and mitral regurgitation, graft replacement was feasible with meticulous perioperative circulatory management using partial extra-corporeal circulation and intra-aortic balloon pumping. However, a prompt registration for heart transplantation and an aortic surgery concomitant with implantation of left ventricular assisted device should have been considered to save the patient.
