Perceptions and practice patterns of cancer survivorship care among Japanese gynecologic oncologists: The JGOG questionnaire survey / 부인종양

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.

Clinicopathologic features, treatment, prognosis and prognostic factors of neuroendocrine carcinoma of the endometrium: a retrospective analysis of 42 cases from the Kansai Clinical Oncology Group/Intergroup study in Japan / 부인종양

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.

Decreased ARID1A expression is correlated with chemoresistance in epithelial ovarian cancer / 부인종양

OBJECTIVE: Loss of ARID1A is related to oncogenic transformation of ovarian clear cell adenocarcinoma. The present study was conducted in epithelial ovarian cancer of all tissue types to investigate whether an increased or decreased expression level of ARID1A can be a prognostic factor for ovarian cancer or can influence the sensitivity to anticancer drugs. METHODS: The expression level of ARID1A was investigated in 111 patients with epithelial ovarian cancer who received initial treatment at the Hirosaki University Hospital between 2006 and 2011. The expression level of ARID1A was immunohistochemically graded using staining scores, which were calculated by multiplying the staining intensity of the nuclei by the stain-positive area. RESULTS: The level of ARID1A was significantly lower in clear cell adenocarcinoma than in other histologic types. Among the patients with stage III, IV cancer (n=46), the level of ARID1A was significantly lower (p=0.026) in patients who did not achieve complete response (CR; n=12) than in patients who achieved CR (n=34). The level of ARID1A was relatively lower (p=0.07) in patients who relapsed after achieving CR (n=21) than in patients who did not relapse (n=13). When the staining score of 0 was defined as ARID1A-negative and other staining scores were defined as ARID1A-positive, there was significant difference in progression-free survival between ARID1A-negative (n=11) and ARID1A-positive (n=35) patients in stage III, IV disease. CONCLUSION: The result suggests that decreased ARID1A expression is correlated with chemoresistance and may be a predictive factor for the risk of relapse of advanced cancer after achieving CR.
