Informed consent forms for gynecologic cancer surgery: recommendations from the Korean Society of Gynecologic Oncology

The sociomedical environment is changing. In the traditional physician-patient relationship, the physician was authoritative and the patient was obedient. The contractual relationship featured patient consent to the physician’s decision. Today, the physician must explain fully the planned medical treatment, and any alternative, to the patient, who has the right to choose her treatment after considering the benefits and side-effects. The Korean Society of Gynecologic Oncology thus decided to standardize the surgical consent forms to meet the legal requirements of modern medicine, improve patient understanding of the surgical details, and protect medical staff from legal disputes. To determine the format and content, subcommittees for each cancer type collected and reviewed all relevant articles and the current consent forms of domestic medical institutions. After several meetings, 16 basic items to be included for each type of gynecologic cancer were selected. Also, to help patients understand the surgical details, figures were included. The revised forms were legally reviewed in terms of the appropriateness of the format and content. We also developed English versions to provide adequate information for foreign patients. We hope that these efforts will promote trust between patients and physicians, and contribute to effective treatment by laying a foundation of mutual respect.

The incidence and survival of cervical, ovarian, and endometrial cancer in Korea, 1999-2017: Korea Central Cancer Registry

Objective@#The three major gynecologic cancers are cervical, endometrial, and ovarian cancer. This study aimed to describe the 19-year trends and survival rates in cervical, endometrial, and ovarian cancer in a Korean female population. @*Methods@#We searched the Korea Central Cancer Registry to identify patients with gynecologic cancer between 1999 and 2017. Age-standardized rates and annual percent changes were calculated. The relative survival rate (RSR) was reported by histology, age, and stage for each gynecological cancer. @*Results@#The total number of cervical, endometrial, primary peritoneal, ovarian epithelial, fallopian tube (POFT) cancer was 134,863, with the number of cases increasing every year: 6,077 in 1999 to 8,011 in 2017. The incidence of cervical cancer has decreased; however, that of POFT and endometrial cancer has increased. The 5-year RSR of cervical, POFT, and endometrial cancer was reported to be 80.8%, 61.4%, and 88.1%, respectively. In the case of cervical cancer, squamous cell carcinoma showed better survival than other histology (82.8% vs. 73.5%). Furthermore, in the case of endometrial cancer, endometrioid histology had substantially better 5-year RSR than the others (93.2% vs. 76.5%). Contrastingly, in the case of ovarian cancer, serous carcinoma had worse 5-year RSR than other types of histology. @*Conclusion@#The incidence rates for gynecologic cancers increased from 2005 to 2017, with an annual increase of 2.76 per year until 2017. Endometrial cancer had the highest RSR, while ovarian cancer had the lowest. Active cancer screening and the introduction of effective treatments might have contributed to the improved RSRs of gynecologic cancers.

Real world effectiveness and safety of pegylated liposomal doxorubicin in platinum-sensitive recurrent ovarian, fallopian, or primary peritoneal cancer: a Korean multicenter retrospective cohort study / 부인종양

OBJECTIVE@#To evaluate the effectiveness and safety of the combination of pegylated liposomal doxorubicin with carboplatin (CD) compared with those of carboplatin and paclitaxel (CP) for platinum-sensitive recurrent ovarian, fallopian, or primary peritoneal cancer in a real-world setting in Korea.@*METHODS@#We enrolled relevant patients from 9 institutions. All patients received CD or CP as the second- or third-line chemotherapy in routine clinical practice during 2013–2018. The primary endpoints were progression-free survival (PFS) and toxicity. The secondary endpoint included the objective response rate (ORR).@*RESULTS@#Overall, 432 patients (224 and 208 in the CD and CP groups, respectively) were included. With a median follow-up of 18.9 months, the median PFS was not different between the groups (12.7 vs. 13.6 months; hazard ratio, 1.161; 95% confidence interval, 0.923–1.460; p=0.202). The ORR was 74.6% and 80.1% in the CD and CP group, respectively (p=0.556). Age and surgery at relapse were independent prognostic factors. More patients in the CD group significantly experienced a grade 3 to 4 hematologic toxicity and hand-foot syndrome (13.8% vs. 6.3%), whereas grade 2 or more alopecia (6.2% vs. 36.1%), peripheral neuropathy (4.4% vs. 11.4%), and allergic/hypersensitivity reaction (0.4% vs. 8.5%) developed more often in the CP group.@*CONCLUSIONS@#The safety and effectiveness of chemotherapy with CD in a real-world setting were consistent with the results from a randomized controlled study. The different toxicity profiles between the 2 chemotherapy (CD and CP) regimens should be considered in the clinical practice.TRIAL REGISTRATION: ClinicalTrials.gov Identifier: NCT03562533

Survival outcomes of adjuvant radiotherapy and chemotherapy in women with stage I serous papillary and clear cell carcinoma of the endometrium: a Korean multicenter study / 부인종양

OBJECTIVE: To compare the survival outcomes of adjuvant radiotherapy and chemotherapy in women with uterine-confined endometrial cancer with uterine papillary serous carcinoma (UPSC) or clear cell carcinoma (CCC). METHODS: Medical records of 80 women who underwent surgical staging for endometrial cancer were retrospectively reviewed. Stage I UPSC and CCC were pathologically confirmed after surgery. Survival outcomes were compared between the adjuvant radiotherapy and chemotherapy groups. RESULTS: Fifty-four (67.5%) and 26 (32.5%) women had UPSC and CCC, respectively. Adjuvant therapy was administered to 59/80 (73.8%) women (25 radiotherapy and 34 chemotherapy). High preoperative serum cancer antigen-125 level (25.1±20.2 vs. 11.5±6.5 IU/mL, p 0.999) and overall survival (77.5% vs. 87.8%, p=0.373) rates were similar between the groups. Neither radiotherapy (hazard ratio [HR]=1.810; 95% confidence interval [CI]=0.297–11.027; p=0.520) nor chemotherapy (HR=1.638; 95% CI=0.288–9.321; p=0.578) after surgery was independently associated with disease recurrence. CONCLUSION: Our findings showed similar survival outcomes for adjuvant radiotherapy and chemotherapy in stage I UPSC and CCC of the endometrium. Further large study with analysis stratified by MI or LVSI is required.

Primary nasal type NK/T cell lymphoma of the endometrium : A case report / 대한산부인과학회지

Non-Hodgkin lymphoma can involve the female genital tract usually as a manifestation of systemic disease, the vast majority of cases being B cell lineage. We report here one case of nasal type NK/T cell lymphoma arising in the uterus, of a 45-year-old Korean woman. The endometrium and myometrium showed diffuse infiltrative mass with hemorrhage and necrosis. Microscopic examination of the tumor revealed medium-sized atypical lymphoid cells. The tumor cells were positive for cytoplasmic CD3 and CD56, and were negative for vimentin, CD10, smooth muscle actin and desmin. Furthermore, In situ hybridization analysis for Epstein-Barr virus (EBV) RNA was positive. The histopathologic and immunohistochemical findings were consistent with extranodal nasal type NK/T cell lymphoma. We report this case to illustrate that NK/T cell lymphomas can involve, and rarely arise in, the gynecologic tract.

Clinical analysis of laparoscopic surgery of tuboovarian abscess in acute pelvic inflammatory disease / 대한산부인과학회지

OBJECTIVE: To evaluate the clinical characteristics between patients with tuboovarian abscess and those presenting with non-tuboovarian abscess in acute pelvic inflammatory disease according to the operation findings. METHODS: The patients were divided into 2 groups based on the operation findings at laparoscopic surgery; 56 patients diagnosed with evidence of tuboovarian abscess and 74 patients diagnosed with acute pelvic inflammatory disease without tuboovarian abscess. Those were compared with respect to patient characteristics, clinical and laboratory findings depending on the significant differences. RESULTS: There were no significant differences between the two groups considering the percentage of age, parity, mean abortion rate and rate of the history of previous pelvic inflammatory disease. But there were differences in mean white blood cell count, erythrocyte sedimentation rate and C-reactive protein level. A higher number of patients having intrauterine devices were observed in the tuboovarian abscess group than in the non-tuboovarian abscess group. Also, statistical significance was noted in hospital stay after operation but there was no difference in number of sick days prior to operation. CONCLUSION: Our results suggest that some variables noted between the tuboovarian abscess group and acute pelvic inflammatory disease group. These results make easier to calculate diagnostic accuracy of patients prone to developing tuboovarian abscess and prevent subsequent complications from the delay of treatment if sensitivity, specificity, negative and positive predictive values were assessed.
