RESUMO
AIM: Minimally invasive surgeries for endometrial cancer are increasing worldwide. In Japan, some articles have examined surgical outcomes, but only a few have addressed oncological outcomes. This study aims to compare robot surgery, laparoscopic surgery, and laparotomy in terms of surgical and oncological outcomes within a low-risk group for endometrial cancer recurrence. METHODS: This study included patients with endometrial cancer deemed to be at low risk of recurrence and who underwent surgery between January 2011 and December 2020. We studied 99 patients who underwent robot surgery, 85 patients who underwent laparotomy, and 77 patients who underwent laparoscopic surgery. Surgical and oncological outcomes were compared retrospectively for these groups of patients. RESULTS: The median follow-up period was 47, 61, and 60 months in the laparotomy, laparoscopy, and robotic groups, respectively. The three groups had similar perioperative and pathological data. No significant differences in overall survival and disease-free survival were observed among the groups. Univariate and multivariate analyses conducted on the overall study population for disease-free survival and overall survival showed that the surgical approach did not have any influence. Minimally invasive surgery groups had longer operating times compared to the laparotomy group, but they had significantly less blood loss. The number of resected pelvic lymph nodes was similar, and the complication rate was not significant. CONCLUSIONS: Robot-assisted surgery and laparoscopic surgery were found to be less invasive and showed similar oncologic outcomes compared to laparotomy surgery for endometrial cancer in patients with a low risk of recurrence.

Mesonephric-like adenocarcinoma (MLA) has recently been described as a tumor of the endometrium or ovaries, which, morphologically and immunohistochemically, resembles mesonephric adenocarcinoma arising mostly in the uterine cervix. Herein, we report, to our knowledge, the first case of ovarian MLA that developed into an extremely rapidly growing recurrent mesonephric-like carcinosarcoma, as confirmed by a genomic profiling test. A 51-year-old woman underwent chemotherapy with complete debulking surgery for ovarian carcinoma. Pathologically, the patient was diagnosed with stage IVB ovarian MLA. Subsequent to 15 months of complete remission, an enhanced computed tomography scan revealed a solid tumor of 10 cm diameter in the abdominal cavity. Secondary surgery was terminated with a 2 cm 2 tumor biopsy specimen collection considering perioperative complications. Histologically, the tumor consisted of short spindle cells, and immunohistochemical staining revealed a rhabdomyosarcomatous profile without an epithelial component. Despite treatment for the sarcoma, she died 3 months after the detection of the tumor. The genomic profiling of the primary ovarian carcinoma and secondary resected tumor biopsy specimens revealed an identical KRAS mutation in both. Therefore, we concluded that the ovarian MLA recurred with a rhabdomyosarcoma component.
RESUMO
AIM: To evaluate changes of treatment strength and its impact on prognosis in older patients with ovarian cancer. METHODS: We compared relative dose intensity (RDI) as a representative of treatment strength, prognosis, and other features between older (≥65 years) and younger patients (<65 years) retrospectively. Seventy-seven older patients of 301 who received dose-dense-paclitaxel-carboplatin (dTC) and 93 older patients of 304 who received conventional-paclitaxel-carboplatin (cTC) from the Japanese Gynecologic Oncology Group (JGOG) 3016 clinical trial were analyzed. RESULTS: The RDI of older patients was lower than that of younger patients in cTC (87.4% vs. 90.8%, p = 0.009) but not in dTC (79.0% vs. 81.2%, p = 0.205). In both regimens, older patients had worse overall survival than younger patients: hazard ratio [HR] = 1.80; 95% confidence interval [CI]: 1.25-2.59; p = 0.001 for dTC, and HR = 1.59; 95% CI: 1.15-2.19; p = 0.04 for cTC. However, the RDI was not determined as a prognostic factor statistically. The prognostic factors identified by multivariate analysis for both regimens were clinical stage and residual disease; for dTC were age, performance status, and serum albumin; and for cTC was white blood cell count. There was no difference in neutropenia observed between age groups in either regimen. CONCLUSIONS: The RDI of older patients varies according to the administered schedule and is not always lower than that of younger patients. Older patients with comparable treatment strength to younger patients in the dTC group did not accomplish the same level of prognosis as younger patients. Other biologic factors attributable to aging may affect prognosis.

OBJECTIVE: This study aimed to assess gynecologic oncologists (GOs)' perceptions and attitudes toward cancer survivorship to help improve survivor care. METHODS: We conducted a web-based questionnaire survey about survivorship issues for the GOs belonging to the Japan Gynecologic Oncology Group. We analyzed the proactiveness of the participants toward addressing 25 survivor issues. In addition, the practice patterns and barriers to care for survivors' long-term health issues, such as second primary cancer (SPC) and lifestyle-related diseases (LSRD), and return-to-work (RTW) support were assessed. RESULTS: We received 313 responses. The respondents had a mean of 22 years of physician experience. The ratio of men to women was approximately 7:3, and 84.7% worked at facilities for multidisciplinary cancer treatment. The respondents' proactiveness for addressing psychosocial problems was significantly lower than physical and gynecological issues (p<0.01 by χ² test). However, most GOs tried to contribute to such issues according to patients' demands. Women GOs were more proactively involved in some survivorship issues than the men (p<0.05 by logistic regression analysis). The rates of the respondents who proactively discussed SPC, LSRD, and RTW were unexpectedly high (60.7%, 36.1%, and 52.4%, respectively). However, the GOs only provided verbal support for these issues in many cases. CONCLUSION: The Japanese GOs were enthusiastic about survivorship care. However, their tendency to deal with survivors' problems through their own knowledge and judgments raises concerns about the quality of care. Therefore, creating survivorship care guidelines and enhancing multidisciplinary collaboration should be prioritized.

Introduction: We would like to present a rare case of metastatic renal tumor. Case presentation: A 60-year-old woman presented to our department with a left renal tumor. She underwent a total hysterectomy and right adnexal resection for a stage IA ovarian granulosa cell tumor approximately 15 years ago, followed by left adnexal resection and postoperative chemotherapy with gemcitabine and paclitaxel 6 years ago. She received six courses of gemcitabine and carboplatin to treat a stage IC clear cell adenocarcinoma of the ovary.The patient was diagnosed with the left renal tumor and underwent a laparoscopic left nephrectomy. Immunostaining was positive for α-inhibin and SF-1 and showed FOXL2 402CâG (C134W) mutation. Finally, the patient was diagnosed with renal metastasis of a granulosa cell tumor. Conclusion: To our knowledge, this is a very rare case of renal metastasis of a granulosa cell tumor with the FOXL2 mutation in an adult.
RESUMO
A previous retrospective study of a neuroendocrine carcinoma of the endometrium including 42 cases employed a central pathologic review to ensure the reliability of the findings. However, the pathological processes were not described in detail. In this study, we further analyzed these processes and the results of pretreatment endometrial cytology of neuroendocrine carcinoma. Of the 65 patients from 18 institutions registered in the study, 42 (64.6%) were diagnosed with neuroendocrine carcinoma of the endometrium based on the central pathological review. Thirteen of the 23 excluded cases conflicted from their original diagnoses: 5 (38.5%) were diagnosed with endometrioid adenocarcinoma, 5 (38.5%) with undifferentiated carcinoma, and 3 (23.1%) with carcinosarcoma. Immunohistochemical staining led to a change in diagnosis for 8 (61.5%) of the 13 cases. Pretreatment endometrial cytology was examined in 38 (90.5%) cases; 34 (89.5%) of these 38 cases were found, or suspected, to be positive. To ensure the selection of appropriate therapy and keeping patients correctly informed, it is important to distinguish neuroendocrine carcinoma from other similar histologic types. Endometrial cytology may help in the early detection of this disease.

Chemotherapy-induced peripheral neuropathy (CIPN) is a frequently observed treatment-related adverse effect, particularly associated with taxane-based chemotherapy, which affects the quality of life of the patients. To date, CIPN has been subjectively evaluated by patients or physicians. Intraepidermal electrical stimulation (IES) may be applied to evaluate the function of small fibers by measuring pain threshold, and assess the degree of diabetic peripheral neuropathy. The aim of the present study was to evaluate CIPN objectively by using IES. The pain threshold measured by IES in patients with gynecological cancer who underwent taxane-based chemotherapy was compared with the clinical grading scale of peripheral neuropathy (National Cancer Institute Common Terminology Criteria for Adverse Events, version 4.0). A total of 57 patients were evaluated (151 measurements). The median age of the patients was 63 years. The number of measurements with clinical grades of 0, 1 and ≥2 was 49, 57 and 45, respectively. The mean pain threshold was 0.1, 0.14 and 0.18 mA for grades 0, 1 and ≥2, respectively. Therefore, the mean pain threshold significantly increased with the progression of the clinical grade. The measurement of pain threshold by using IES may be a reliable indicator for quantitative evaluation of CIPN.
RESUMO
BACKGROUND: Postoperative ileus is a major complication of abdominal surgical procedures. The purpose of this study was to investigate preventive effect of daikenchuto (DKT) on onset of ileus in patients who received gynecological surgery for malignant tumors. METHODS: A total of 904 patients who received gynecological surgery for malignant tumors by opening retroperitoneum along with retroperitoneal lymph node dissection during a period between 2004 and 2018 were included in this retrospective study. The retroperitoneum was not sutured in all patients. Comparisons were made for proportion of patients developing ileus (frequency of postoperative ileus onset), timing of ileus onset, and treatment types for ileus among following three groups: a group treated with enema or laxatives to release gas if they did not pass the intestinal gas for 3 days postoperatively (Group A, n = 152); a group treated with adhesion-inhibitory absorptive barrier at the opening to the retroperitoneum (Group B, n = 188); and a group treated with adhesion-inhibitory absorptive barrier and oral intake of DKT 7.5 g per day (Group C, n = 564). RESULTS: The frequency of ileus onset significantly decreased in both Groups B (4.8%) and C (3.5%) compared to Group A (16.4%). Furthermore, the frequency of ileus onset was significantly less in Group C compared to Group B. For the treatment types, frequency of ileus, which was successfully treated only with conservative therapy, was the same for Groups B and C. However, incidence of serious ileus that required surgery decreased by 45% in Group C (2/564) compared to Groups A (2/152) and B (3/188). CONCLUSIONS: Results suggest that DKT prevents development of serious ileus after gynecological surgery for malignant tumors and therefore contributes to improvement in patients' QOL.

The aim of the present study was to evaluate the oncologic safety and reproductive outcome in patients with stage I epithelial ovarian cancer (EOC) treated with fertility-sparing surgery (FSS). Women aged ≤40 years with stage I EOC who had undergone FSS between 2000 and 2010 were retrospectively reviewed. Survival was examined using the Kaplan-Meier method and statistical significance was analyzed using the log-rank test. A total of 29 EOC patients (stage IA, n=14; stage IC1 n=6; stage IC3, n=9) from seven participating institutions belonging to the Tohoku Gynecologic Cancer Unit were enrolled. After a median follow-up duration of 60.6 months (range, 6-135 months), five patients (17.2%) experienced tumor recurrence. The respective five-year relapse-free survival (RFS) and overall survival (OS) rates were 90.9 and 100% for stage IA/IC1, and 43.8 and 87.5% for stage IC3. Significant differences in RFS were observed between stage IA/IC1 and IC3 patients (P=0.026). However, there was no significant difference in OS between patients with 1A/1C1 and those with 1C3 (P=0.712). After FSS, seven pregnancies occurred in five patients, which resulted in the birth of six healthy children. The results of the present study confirmed that FSS may be an acceptable treatment method for stage IA and IC1 EOC, exhibiting a favorable reproductive outcome. However, the safety of FSS for treating stage IC3 EOC is uncertain and warrants further investigation.
RESUMO
BACKGROUND: The proportion of elderly Japanese people (age ≥ 65 years) is currently 27.7%, and the average life span of women is 87.14 years, both of which are unprecedented. In gynecologic cancer, evidence of treatment for the elderly is scarce, and treatment policies are determined by each facility. The aim of the present study was to investigate the status of treatment policies for elderly patients with gynecologic cancer. METHODS: A web-based questionnaire regarding how treatment strategies are currently determined for elderly patients with gynecologic cancer was conducted on gynecologic oncologists to develop a tool for the objective evaluation of treatment policy decisions for elderly patients. RESULTS: The responses showed that 48% of the gynecologic oncologists were aware of comprehensive geriatric assessment (CGA), but only 6% had actually conducted CGA. Age, comorbidities, performance status, and pretreatment evaluations were regarded as important in determining the treatment strategy. Invasive treatments such as radical hysterectomy and para-aortic lymph node dissection tended to have age limits. CONCLUSIONS: These findings suggest that awareness of CGA is low in Japan, and that elderly people may not be given standard therapy, which highlights the importance of building on these findings by gathering further evidence and developing a new tool for predicting treatment outcomes for elderly patients with gynecologic cancer.

OBJECTIVE: We conducted a retrospective, multi-institutional, collaborative study to accumulate cases of neuroendocrine carcinoma of the endometrium, to clarify its clinicopathologic features, treatment, prognosis and prognostic factors to collate findings to establish future individualized treatment regimens. To our knowledge, this is the largest case study and the first study to statistically analyze the prognosis of this disease. METHODS: At medical institutions participating in the Kansai Clinical Oncology Group/Intergroup, cases diagnosed at a central pathologic review as neuroendocrine carcinoma of the endometrium between 1995 and 2014 were enrolled. We retrospectively analyzed the clinicopathologic features, treatment, prognosis and prognostic factors of this disease. RESULTS: A total of 65 cases were registered from 18 medical institutions in Japan. Of these, 42 (64.6%) cases were diagnosed as neuroendocrine carcinoma of the endometrium based on the central pathological review and thus included in the study. Advanced International Federation of Gynecology and Obstetrics stages (stage III and IV) and pure type small cell neuroendocrine carcinoma cases had a significantly worse prognosis. Upon multivariate analysis, only histologic subtypes and surgery were significant prognostic factors. Pure type cases had a significantly worse prognosis compared to mixed type cases and complete surgery cases had a significantly better prognosis compared to cases with no or incomplete surgery. CONCLUSION: Our findings suggest that complete surgery improves the prognosis of neuroendocrine carcinoma of the endometrium. Even among cases with advanced disease stages, if complete surgery is expected to be achieved, clinicians should consider curative surgery to improve the prognosis of neuroendocrine carcinoma of the endometrium.

OBJECTIVE: We conducted a multicenter clinicopathological study to characterize patients with high-grade serous carcinoma presenting as primary peritoneal carcinoma (clinical PPC). METHODS: At 9 sites in Japan, patients with clinical PPC diagnosed according to Gynecologic Oncology Group criteria were enrolled retrospectively. The Gynecologic Oncology Group criteria allow for minor ovarian involvement by high-grade serous carcinoma. There was no systematic detailed histopathological review of the fallopian tubes to determine whether they were involved by serous carcinoma. RESULTS: There were 139 patients and 64% were aged 60 years or older. Median pretreatment serum CA-125 was 1653.5 IU/mL. Pretreatment performance status was poor in more than 50%, endometrial cytology was positive in 40.3%, and the preoperative clinical diagnosis was correct in 72.7%. Primary debulking surgery was performed in 36% of patients, whereas 64% underwent neoadjuvant chemotherapy (NAC) with interval debulking surgery (IDS). The main tumor sites were the upper abdomen (greater omentum), extrapelvic peritoneum, mesentery, and diaphragm. Lymph node metastasis was found in 46.8% of patients undergoing systematic retroperitoneal node dissection. The optimal surgery rate was 32.0% with primary debulking surgery versus 53.9% with NAC and IDS (P = 0.0139). The response rate was 82.0% with NAC and 80.6% with postoperative chemotherapy. Median progression-free survival was 19.0 months and median overall survival was 41.0 months. Multivariate analysis showed that prognostic factors for progression-free survival were NAC and residual tumor diameter after debulking surgery, whereas the only prognostic factor for overall survival was the residual tumor diameter. CONCLUSIONS: This study identified various characteristics of clinical PPC. Neoadjuvant chemotherapy with IDS is a reasonable treatment strategy, and complete debulking surgery is optimum.

PURPOSE: We report a phase II clinical study of the combination of irinotecan (CPT-11) and pegylated liposomal doxorubicin (PLD) in platinum- and taxane-resistant recurrent ovarian cancer, based on the recommended doses determined in a phase I trial. METHODS: PLD was administered intravenously at a dose of 30 mg/m2 on day 3. CPT-11 was administered intravenously at a dose of 80 mg/m2 on days 1 and 15, according to the recommendations of the phase I study. A single course of chemotherapy lasted 28 days, and patients underwent at least 2 courses until disease progression. The primary endpoint was antitumor efficacy, and the secondary endpoints were adverse events, progression-free survival (PFS), and overall survival (OS). RESULTS: The response rate was 32.3% and the disease control rate was 64.5%. Grade 3 and 4 neutropenia, anemia, and a decrease in platelet count were observed in 17 (54.9%), 3 (9.7%), and 1 patient (3.2%), respectively. In terms of grade 3 or higher non-hematologic toxicities, grade 3 nausea occurred in 1 patient (3.2%), vomiting in 3 patients (9.7%), and grade 3 diarrhea and fatigue in 1 patient (3.2%). The median PFS and OS rates were 2 months and not reached, respectively. Of the 11 patients with a treatment-free interval (TFI) of ≥3 months, the response rate was 63.3%, and the median PFS was 7 months. CONCLUSIONS: The treatment outcomes for the 31 patients enrolled in this study were unsatisfactory. However, sub-analysis suggested that patients with a TFI of ≥3 months had a good response rate and PFS. This suggests that CPT-11/PLD combination therapy may be a chemotherapy option for platinum-resistant recurrent ovarian cancer.

Protoporphyrin IX (PpIX) levels are crucial to the antitumor action of photodynamic therapy (PDT). In the present study, the underling molecular mechanisms for the variation in PpIX levels in ovarian cancer cells were investigated. Five ovarian cancer cell lines were subcutaneously grafted onto the backs of nude mice. Once tumors had developed, 5-aminolevulinic acid methyl ester hydrochloride (methyl-ALA) was administered intraperitoneally and the tumor was irradiated twice/week. PpIX levels in the tumor were assayed using high-performance liquid chromatography. Enzymes involved in heme synthesis and degradation were screened using a microarray technique. Expression of the glutathione transferase Omega-1 (GSTO1) gene involved in the conversion of PpIX into heme in cells was quantified using the reverse transcription-quantitative polymerase chain reaction. In HTOA, HRA and DISS cells, PDT resulted in significant tumor shrinkage in comparison with the controls. In MCAS and TOV21G cells, no significant alterations in tumor growth were identified compared with the untreated cells. PpIX levels increased significantly in HTOA, DISS and HRA cells compared with in MCAS and TOV21G cells. A comparison of genetic profiles using PDT-sensitive DISS cells and PDT-resistant MCAS cells indicated that MCAS cells exhibited significantly increased levels of δ-aminolevulinate synthase (a rate-limiting enzyme in heme synthesis), heme oxygenase 2 (an enzyme that degrades heme into biliverdin), and biliverdin reductase B (an enzyme that reduces biliverdin into bilirubin) in comparison with DISS cells. The level of GSTO1 expression in HTOA, HRA and DISS cells was ~2.5-fold that in MCAS and TOV21G cells. Sensitivity to PDT is related to PpIX levels in cells. The results of the present study suggested that PpIX tends not to accumulate in PDT-resistant cells despite active heme synthesis and degradation, and that high levels of GSTO1 expression are associated with increased sensitivity to PDT.
RESUMO
The Japanese Gynecologic Oncology Group (JGOG) is leading Japan in the treatment of gynecological malignancies. The JGOG consists of three treatment committees focusing on uterine cervical cancer, endometrial cancer, and ovarian cancer. Each committee makes efforts to improve treatment and diagnosis. In addition, the Supportive and Palliative Care Committee was established in 2015. Novel studies of supportive care and palliative care have been initiated by this committee. Furthermore, surveys about not only treatment results such as overall survival rates but also quality of life (QOL) and cost-effectiveness assessments are performed by the ovarian cancer committee. Improvements of patients' QOL in the treatment of gynecological malignancies were divided into three concepts as follows: QOL associated with cancer treatment, health care after cancer therapy, and progression of cancer. In this review, we report the contributions and future plans for the improvement of QOL in patients with gynecological malignancies.

Purpose: To evaluate palliative care for patients with gynecologic cancer in Japan. Materials and Method: A questionnaire asking facility characteristics, systems to coordinate palliative care, current status of end-of-life care, provision of symptom relief, palliative radiation therapy and chemotherapy, and cases of death from gynecological cancer, was mailed to facilities treating gynecologic cancer. Results: A total of 115 facilities (29.3% of the total) responded to the questionnaire. Of these, 33.0 (29.0%) had a palliative care ward. End-of-life care was managed by obstetricians and gynecologists in 72.0% of the facilities. The site where end-of-life care was provided was most often a ward in the department where the respondent worked. The waiting period for transfer to a hospice was 2 weeks or more in 52% of facilities. Before the start of primary treatment, pain control was managed by obstetrians and gynecologists in 98.0% of facilities. Palliative radiation therapy or chemotherapy was administered at 93.9% and 92.0% of facilities, respectively. Of the 115 facilities, 34.0 (29.6%) reported cases of death from gynecological cancer. There were 1,134 cases of death. The median time between the last cycle of chemotherapy and death was 85 days for all gynecological cancers. The proportion of patients receiving chemotherapy in the last 30 and 14 days of life were 17.4% and 7.1%, respectively. Conclusions: This large-scale survey showed characteristics of palliative care given to patients with gynecologic cancer in Japan. Assessment of death cases showed that the median time between the last cycle of chemotherapy and death was relatively short.
RESUMO
WAGR syndrome is caused by an 11p13 deletion and includes Wilms' tumor, aniridia, genitourinary anomalies and mental retardation. We encountered a case of a dysgerminoma originating in an ectopic ovary in a woman with WAGR syndrome. Our patient was a 24-year-old nulliparous woman who was diagnosed with WAGR syndrome. The patient had undergone left nephrectomy for a Wilms' tumor and postoperative chemotherapy at the age of 7 months. She also had a history of glaucoma surgery in both eyes, and was followed up at the Department of Pediatrics for diabetes mellitus, hypertension, liver dysfunction and hyperuricemia. The patient was investigated for oliguria and had elevated levels of blood urea nitrogen (45 mg/dl) and creatinine (5.4 mg/dl); she was admitted to the hospital with acute renal failure and a computed tomography scan revealed a pelvic tumor with a long axis of 10 cm that was obstructing the right ureter. Following insertion of a ureteral stent, the tumor was removed. The tumor had developed in the retroperitoneal space independent of the ovaries. The right adnexa were normal. The tumor was histopathologically diagnosed as dysgerminoma. Follicles were found in part of the tumor; it was thus hypothesized that the tumor developed from an ectopic ovary. The patient was administered etoposide after surgery, and has been recurrence-free for 4 years since treatment.
RESUMO
Endometrial cancers are mostly estrogen-dependent. FOXP1 is a P subfamily of forkhead box (FOX), and known as an estrogen-responsive transcription factor. The aims of this study were to examine histological location of FOXP1 in normal and malignant endometrium, and to investigate a possible association between FOXP1 and other factors considered to be involved in pathogenesis of endometrial cancer. The levels of FOXP1, estrogen receptor (ER)α, and ERß expression were examined immunohistochemically in normal and malignant endometrium obtained from 75 women (8 normal, 8 atypical endometrial hyperplasia, and 59 endometrial cancers from grade 1 to 3). The effects of estrogen on ERα, FOXP1, KRAS, and PTEN expression were analyzed in telomerase-immortalized human endometrial stromal cells (T HESCs) by Western blotting. Western blotting was also used to examine the effect of FOXP1 plasmid DNA or siRNA transfection on KRAS and PTEN expression in Ishikawa cells (well differentiated endometrioid adenocarcinoma), HEC-50B cells (poorly differentiated endometrioid adenocarcinoma), and T HESCs, respectively. FOXP1 was expressed in normal and malignant endometrium, but the rate of expression was different depending upon menstrual cycle and pathological grade of malignancy. FOXP1 expression in nucleus and cytoplasm of grade 3 endometrioid cancers was significantly lower than that of grade 1 and 2 ones. Estradiol increased levels of FOXP1 and KRAS expression in a dose- and time-dependent manner in T HESCs cells, and FOXP1 transfection or knockdown led to increase or decrease of KRAS expression but not PTEN. KRAS expression level was significantly related to FOXP1 and ERα levels in cancer tissues. Estradiol did not affect KRAS expression in T HESCs cells transfected with FOXP1 siRNA. These results suggest that FOXP1 is involved in estrogen dependent endometrial cancers through KRAS pathway.
RESUMO
BACKGROUND: The current study examined the effectiveness of concurrent therapy using photodynamic therapy (PDT) and clofibric acid (CA) to treat peritoneal carcinomatosis resulting from ovarian cancer. MATERIALS AND METHODS: Nude rats were used to create a model of peritoneal carcinomatosis resulting from ovarian cancer and the effectiveness of PDT with 5-aminolevulinic acid methyl ester hydrochloride (methyl-ALA-PDT) was determined. The survival time of rats receiving that therapy was compared to the survival time of a control group. Rats with peritoneal carcinomatosis resulting from ovarian cancer were divided into 3 groups: a group that received debulking surgery (DS) alone, a group that received DS+methyl-ALA-PDT, and a group that received DS+methyl-ALA-PDT+CA. The survival time of the 3 groups was compared. Protoporphyrin, a metabolite of methyl-ALA, produces a photochemical action when activated by light. The level of protoporphyrin (the concentration) that reached organs in the abdomen was measured with HPLC. RESULTS: Rats receiving methyl- ALA-PDT had a significantly longer survival time compared to the controls. Rats with peritoneal carcinomatosis that received DS+methyl-ALA-PDT+CA had a significantly longer survival time compared to the rats that received DS alone. Some of the rats that received concurrent therapy survived for a prolonged period. Protoporphyrin was highly concentrated in peritoneal metastases, but only small amounts reached major organs in the abdomen. PDT was not found to result in necrosis in the intestines. CONCLUSIONS: The results indicated that concurrent therapy consisting of PDT with methyl-ALA and CA is effective at treating peritoneal carcinomatosis resulting from ovarian cancer without damaging organs.

We incorporated liquid-based cytology (LBC) in population-based screening for cervical cancer. The usefulness of using LBC in mass screening for cervical cancer was examined. From 2009 to 2014, 157,061 individuals underwent mass screening for cervical cancer in Aomori Prefecture. From 2009 to 2011, cells were collected from 82,218 individuals and the specimens were conventionally prepared (CP). From 2012 to 2014, cells were collected from 74,843 individuals and the specimens were prepared using LBC (TACAS™). Cytology results for the 2 sets of specimens were compared and differences in cytologic features were examined. ASC-US and more severe lesions were detected at a rate of 1.13 % by CP and 1.44 % by LBC, so LBC had a 1.3-fold higher rate of detection. LBC had a 1.6-fold higher rate of LSIL detection and a 1.2-fold higher rate of HSIL detection. CP detected cancer in 20 cases at a rate of 0.024 % while LBC detected cancer in 18 cases at a rate of 0.024 %. Cytodiagnosis of the 18 cases of SCC that LBC identified revealed that 7 were SCC, 8 were HSIL, and 3 were ASC-H. Atypical cells tended to be smaller with TACAS™. LBC reduced the time needed for microscopic examination of a single specimen by 42 % in comparison to CP. LBC using TACAS™ allowed the detection of slight lesions and slight changes in cells. LBC can lessen the burden on medical personnel and may lead to improved accuracy.
