To evaluate the efficacy of the retroperitoneal approach (RP) when compared with the transperitoneal approach (TP) in elective aortoiliac reconstruction, 41 cases were reviewed. From February 1987 through October 1991, 16 patients underwent aortoiliac reconstruction through the TP approach and 25 patients underwent operation through the RP approach for abdominal aortic aneurysms (AAA). The TP approach was associated with larger intraoperative blood loss (648.6±416.5ml) when compared with the RP approach (357.7±208.9ml) (p<0.01). The TP approach was associated with greater intraoperative blood transfusion (2093.8±1179.0ml) when compared with the RP approach (1010.4±905.3ml) (p<0.01). Both groups had similar operative times. Postoperative initiation of oral water intake was prolonged in the TP group (50.2±27.4hr) when compared with the RP group (22.3±8.9hr) (p<0.01). Postoperative initiation of walking training was prolonged in the TP group (88.7±37.1hr) when compared with the RP group (60.1±23.2) (p<0.01). This experience demonstrates that the RP approach is a preferable alternative to the TP approach in elective aortoiliac reconstruction.

From May 1975 to August 1991, 90 patients (56 males and 34 females) underwent Bentall's operations or its modified technique. In our modified technique the coronary ostium is cut out like a button and anastomosed to the aortic graft and aortic grafts are not wrapped by the aortic wall. Preoperative diagnoses were AAE (25 patients, 28%), Stanford type A dissection (19, 21%), Marfan's syndrome (16, 18%), aortitis syndrome (12, 13%), AR+ascending aortic aneurysm (6, 7%), syphilitic aortitis (5, 6%), AS+ascending aortic aneurysm (3, 3%), Valsalva's sinus aneurysm (2, 2%) and other diseases (2, 2%). The hospital mortality rate was 17% (15/90) for all cases. The hospital mortality for aortic dissection (37% (7/19)) and reoperation cases (75% (3/4)) were very high. There were 10 cases of late death and the 10 year actuarial survival rate was 66.3%. Among 11 cardiovascular events which occured in the late phase, 5 were dissection at other aortic sites in the type A dissection and Marfan syndrome cases, and 3 were pseudoaneurysm formation at the site of coronary or the aortic anastomosis in the aortitis syndrome cases, and a detachment of the composite graft in the Marfan's syndrome cases. The 10-year event-free rate was 92.0% for non-specific AAE, 68.8% for aortitis syndrome, 61.9% for Marfan's syndrome and 47.3% for Stanford type A dissection. Non-specific AAE had excellent long-term results, but Marfan's syndrome and dissection had poor results. The button technique for coronary reconstruction is effective for all cases and its long term results are good, but, even with this technique, coronary pseudo-aneurysm occured in cases of aortitis syndrome.

OBJECTIVE: The aim of this study is to evaluate the efficacy of carboplatin-paclitaxel (TC) as an initial treatment in patients with the International Federation of Gynecology and Obstetrics (FIGO) stage IVb cervical cancer. METHODS: We retrospectively reviewed seven patients with stage IVb cervical cancer who have been primarily treated with TC. The activity and the toxicity were evaluated. Response rate was the main endpoint. RESULTS: Overall, the treatment of TC was well tolerated. The overall response rate was 71.4% (2 complete response, 3 partial response). Although grade 3-4 hematologic toxicities were observed in 3 out of 7 patients (42.8%), no patients experienced grade 3-4 non-hematologic toxicities. When we combined our present results with the previous reports, the overall response rate of TC is 63.6%. CONCLUSION: TC is active and well tolerated in patients FIGO stage IVb cervical cancer. This combination may be considered as an initial treatment regimen in this patient population.

OBJECTIVE: To evaluate the clinical efficiency of identifying patients with suspicious severe lesions by conization among prediagnosed cervical intraepithelial neoplasia (CIN) 1 and 2 patients in Japan. METHODS: The data in a Japanese nation-wide registry for cervical cancer (2009 and 2011) was collected to analyze the clinical efficacy of pre- and postdiagnosis for 13,215 Japanese women who underwent treatment by conization. Their preoperative and postoperative histologic findings and clinical outcomes were evaluated using standard statistical procedures including clinical and demographic characteristics. RESULTS: Almost half of 1,536 women who were treated by conization after the prediagnosis of CIN1 and 2 because the lesions showed no evidence of natural regression actually contained CIN1–2 (45.0%), CIN3 (47%), or invasive cancer (2.7%) in their cervical tissue. They underwent conization either for therapeutic (treatment) (78.5%) or diagnostic (21.5%) reasons. Invasive disease was diagnosed postoperatively more often in diagnostic cases (6.1%) than in therapeutic cases (2.8%). All the patients survived their diagnostic and therapeutic conization after approximately 30 months of follow up. CONCLUSION: Our study shows that the continuous observation of the prediagnosed CIN1 and 2 cases by the combination of cytology, colposcopy and histology in Japan has worked successfully to identify severe lesions by using conization as well in the process.

Objective: BRCA1 and BRCA2 mutation carriers are recommended to undergo risk-reducing salpingo-oophorectomy (RRSO) by age 40 and 45, respectively. However, the carriers have a different way of thinking about their life plan. We aimed to investigate the distribution of age at diagnosis of ovarian cancer (OC) patients to examine the optimal timing of RRSO in the carriers. Methods: We examined a correlation between age at diagnosis of OC and common mutation types in 3,517 probands that received BRCA genetic testing. Among them, germline BRCA1 mutation (gBRCA1m), germline BRCA2 mutation (gBRCA2 m) and germline BRCA wild-type (gBRCAwt) were found in 185, 42 and 241 OC patients, respectively. Results: The average age at diagnosis of OC in gBRCA1m and gBRCA2 m was 51.3 and 58.3 years, respectively, and the difference from gBRCAwt (53.8 years) was significant. The gBRCA2 m carriers did not develop OC under the age of 40. The average age was 50.1 years for L63X and 52.8 years for Q934X in BRCA1, and 55.1 years for R2318X and 61.1 years for STOP1861 in BRCA2 . The age at diagnosis in L63X or R2318X carriers was relatively younger than other BRCA1 or BRCA2 carriers, however their differences were not significant. With L63X and R2318X carriers, 89.4% (42/47) and 100% (7/7) of women were able to prevent the development of OC, respectively, when RRSO was performed at age 40. Conclusion There appears to be no difference in the age at diagnosis of OC depending on the type of BRCA common mutation. Further analysis would be needed.

Background: Poly (adenosine diphosphate)-ribose polymerase (PARP) inhibitors for tumors with homologous recombination deficiency (HRD), including pathogenic mutations in BRCA1/2, have been developed. Genomic analysis revealed that about 20% of uterine leiomyosarcoma (uLMS) have HRD, including 7.5%–10% of BRCA1/2 alterations and 4%–6% of carcinomas of the uterine corpus, and 2.5%–4% of the uterine cervix have alterations of BRCA1/2. Preclinical and clinical case reports suggest that PARP inhibitors may be effective against those targets. The Japanese Gynecologic Oncology Group (JGOG) is now planning to conduct a new investigator-initiated clinical trial, JGOG2052. Methods JGOG2052 is a single-arm, open-label, multi-center, phase 2 clinical trial to evaluate the efficacy and safety of niraparib monotherapy for a recurrent or persistent rare fraction of gynecologic malignancies with BRCA1/2 mutations except for ovarian cancers. We will independently consider the effect of niraparib for uLMS or other gynecologic malignancies with BRCA1/2 mutations (cohort A, C) and HRD positive uLMS without BRCA1/2 mutations (cohort B). Participants must have 1–3 lines of previous chemotherapy and at least one measurable lesion according to RECIST (v.1.1). Niraparib will be orally administered once a day until lesion exacerbation or unacceptable adverse events occur. Efficacy will be evaluated by imaging through an additional computed tomography scan every 8 weeks. Safety will be measured weekly in cycle 1 and every 4 weeks after cycle 2 by blood tests and physical examinations. The sample size is 16–20 in each of cohort A and B, and 31 in cohort C. Primary endpoint is the objective response rate.

Objective: To assess the incidence of bevacizumab-associated gastrointestinal (GI) perforation during first-line treatment of patients with ovarian, fallopian tube, or peritoneal cancer receiving neoadjuvant chemotherapy (NAC) in Japanese real-world clinical practice. Methods: A retrospective study was conducted using a healthcare claims database owned by Medical Data Vision Co., Ltd. (study period, 2008–2020). Patients who initiated first-line treatment of ovarian, fallopian tube, or peritoneal cancer were identified and divided into NAC and primary debulking surgery (PDS) groups. The incidence of bevacizumab-associated GI perforation was compared within the NAC group and between the groups. Results: Paclitaxel + carboplatin (TC) was most commonly used as first-line treatment (39.5% and 59.6% in the NAC and PDS groups, respectively). TC + bevacizumab was used in 9.3% and 11.6% of patients in the NAC and PDS groups, respectively. In the NAC group receiving TC, the proportion of patients with risk factors for GI perforation was lower among patients with versus without concomitant bevacizumab. The incidence of GI perforation in the NAC group was 0.38% (1/266 patients) in patients receiving TC + bevacizumab and 0.18% (2/1,131 patients) in patients receiving TC without bevacizumab (risk ratio=2.13; 95% confidence interval [CI]=0.19 to 23.36; risk difference=0.20; 95% CI=−0.58 to 0.97). None of the 319 patients in the PDS group receiving TC + bevacizumab had GI perforation. Conclusion No notable increase was observed in GI perforation associated with NAC containing bevacizumab. We conclude that bevacizumab is prescribed with sufficient care in Japan to avoid GI perforation.
