Awareness of Symptoms and Risk Factors of Ovarian Cancer in a Population of Women and Healthcare Providers

Use of Period Analysis to Timely Assess Five-Year Relative Survival for Patients with Ovarian Cancer from Taizhou, Eastern China

OBJECTIVE

Ovarian cancer is a deadly gynecologic malignancy with a poor prognosis. It is essential to evaluate the early detection and screening programs of ovarian cancer via timely assessment of long-time survival, particularly in China where those data are incredibly limited. Here, we aimed to provide timely and accurately assessment of long-term survival estimate of ovarian cancer patients from eastern China.

METHODS

Data of 770 ovarian cancer patients diagnosed between 2004-2018 were obtained from four cancer registries in Taizhou, eastern China, were included. We used period analysis to calculate five-year relative survival (RS) of aforementioned ovarian cancer patients for overall and the stratification by age at diagnosis and region.

RESULTS

Our findings demonstrated that the overall five-year RS for ovarian cancer patients in Taizhou between 2014 and 2018 was 69.2%, while urban areas were higher compared to rural areas (77.6% vs. 64.9%). We also observed a significant age gradient with the five-year RS decreasing from 79.6% for age group < 55 years to 66.9% for age group > 74 years. Furthermore, we identified a clear upward trend of five-year RS over the study period, both overall and stratified by region and age at diagnosis.

CONCLUSION

This is the first study in China using period analysis to provide the most up-to-date five-year RS for ovarian cancer patients from Taizhou, eastern China, which reaches 69.2% during 2014-2018. Our results provide valuable information for timely assessment of early detection and screening programs for ovarian cancer in eastern China.

Understanding the Experience of Canadian Women Living with Ovarian Cancer through the Every Woman StudyTM

The Every Woman StudyTM: Canadian Edition is the most comprehensive study to date exploring patient-reported experiences of ovarian cancer (OC) on a national scale. An online survey conducted in Fall 2020 included individuals diagnosed with OC in Canada, reporting responses from 557 women from 11 Canadian provinces/territories. Median age at diagnosis was 54 (11−80), 61% were diagnosed between 2016−2020, 59% were stage III/IV and all subtypes of OC were represented. Overall, 23% had a family history of OC, 75% had genetic testing and 19% reported having a BRCA1/2 mutation. Most (87%) had symptoms prior to diagnosis. A timely diagnosis of OC (≤3 months from first presentation with symptoms) was predicted by age (>50) or abdominal pain/persistent bloating as the primary symptom. Predictors of an acute diagnosis (<1 month) included region, ER/urgent care doctor as first healthcare provider or stage III/IV disease. Regional differences in genetic testing, treatments and clinical trial participation were also noted. Respondents cited substantial physical, emotional, practical and financial impacts of an OC diagnosis. Our national survey has revealed differences in the pathway to diagnosis and post-diagnostic care among Canadian women with OC, with region, initial healthcare provider, specific symptoms and age playing key roles. We have identified many opportunities to improve both clinical and supportive care of OC patients across the country.

The awareness levels of women for gynecologic cancer in Turkey: A cross-sectional study

OBJECTIVE

To investigate the awareness levels of women for gynecologic cancers and the affecting factors.

METHODS

This descriptive and cross-sectional study was conducted with 321 women. Data were collected using a Personal Information Form and the Gynecologic Cancer Awareness Scale (GCAS).

RESULTS

The women's mean score (± standard deviation) on the GCAS was 151.08 ± 3.84. It was determined that the awareness of gynecologic cancer in the women who had undergone gynecologic examination and cervical smear test was higher than in other women. It was also determined that the level of education and income level, the status of having gynecologic examination and operation, and the wanting to get information about gynecologic cancer were not found to affect awareness of gynecologic cancers. The gynecologic cancer awareness of the women increased with the increase in age. It was found that there was no statistically significant relationship between the years of marriage, gravida, and the number of children, and the total GCAS score.

CONCLUSION

Although the gynecologic cancer awareness levels of the participants were high, they were not at the intended level. Education including early diagnosis, risk factors, and symptoms should be provided to women to increase their awareness of gynecologic cancer.

Ovarian Cancer: An Integrated Review

OBJECTIVE

To provide an overview of the risk factors, modifiable and non-modifiable, for ovarian cancer as well as prevention, diagnostic, treatment, and long-term survivorship concerns. This article will also examine current and future clinical trials surrounding ovarian cancer.

DATA SOURCES

A review of articles dated 2006-2018 from CINAHL, UpToDate, and National Comprehensive Cancer Network guidelines.

CONCLUSION

There is no screening test for ovarian cancer and with diagnosis often in the late stages, recurrence is high in this population. Early identification can range from knowing the vague symptoms associated with the cancer to prophylactic surgical removal of at-risk tissue. Standard treatment for ovarian cancer is surgery followed by combination chemotherapy. Although advances are being made, ovarian cancer remains the most fatal female gynecologic cancer.

IMPLICATIONS FOR NURSING PRACTICE

Becoming familiar with and educating women about risk factors and the elusive symptoms of ovarian cancer can increase patient autonomy and advocacy, as well as potentially improve patient outcomes for those affected by ovarian cancer.

When Is "Type I" Ovarian Cancer Not "Type I"? Indications of an Out-Dated Dichotomy

The dualistic classification of epithelial ovarian cancer (EOC) into “type I” and “type II” is widely applied in the research setting; it is used as a convenient way of conceptualizing different mechanisms of tumorigenesis. However, this classification conflicts with recent molecular insights of the etiology of EOC. Molecular and cell of origin studies indicate that while type II tumors could be classed together, type I tumors are not homogenous, even within the histological types, and can have poor clinical outcomes. Type II high grade serous carcinoma and type I low grade serous carcinomas best fit the description of the dualistic model, with different precursors, and distinct molecular profiles. However, endometriosis-associated cancers should be considered a separate group, without assuming an indolent course or type I genetic profiles. Furthermore, the very clear differences between mucinous ovarian carcinomas and other type I tumors, including an uncertain origin, and heterogeneous mutational spectrum and clinical behavior, indicate a non-type I classification for this entity. The impression that only type II carcinomas are aggressive, have poor prognosis, and carry TP53 mutations is an unhelpful misinterpretation of the dualistic classification. In this review, we revisit the history of EOC classification, and discuss the misunderstanding of the dualistic model by comparing the clinical and molecular heterogeneity of EOC types. We also emphasize that all EOC research, both basic and clinical, should consider the subtypes as different diseases beyond the type I/type II model, and base novel therapies on the molecular characteristics of each tumor.
