Impact of Age, Comorbidity, and FIGO Stage on Treatment Choice and Mortality in Older Danish Patients with Gynecological Cancer: A Retrospective Register-Based Cohort Study

Vulvar squamous cell carcinoma in women 80 years and older: Treatment, survival and impact of comorbidities

BACKGROUND

Despite being a disease of mainly older women, little is known about the clinical management of older women with vulvar squamous cell carcinoma (VSCC). We evaluated their daily clinical management compared with younger women, and established the prevalence of comorbidities and its impact on overall survival (OS).

METHODS

All Dutch women diagnosed with VSCC from 2015 to 2020 (n = 2249) were selected from the Netherlands Cancer Registry. Women aged ≥80 years (n = 632, 28%) were defined as "older" patients, women <80 years were considered as "younger". Chi-square tests were performed to evaluate differences in treatment by age group and comorbidities. Differences in OS were evaluated using Kaplan-Meier Curves and log-rank test.

RESULTS

The vast majority of both older (91%) and younger (99%) patients with FIGO IA VSCC received surgical treatment of the vulva. Older FIGO IB-IV VSCC patients were less likely to undergo groin surgery than younger patients (50% vs. 84%, p < 0.01). Performance of surgical treatment of the vulva and groin(s) was not associated with the number of comorbidities in older patients (p = 0.67 and p = 0.69). Older patients with ≥2 comorbidities did have poorer OS compared to women with one or no comorbidities (p < 0.01).

CONCLUSION

The vast majority of older patients underwent vulvar/local surgery. Older patients less often received groin surgery compared to younger patients. The majority of older patients had at least one comorbidity, but this did not impact treatment choice. The poorer survival in older VSCC patients may therefore be due to death of competing risks instead of VSCC itself.

Endometrial Cancer. Guideline of the DGGG, DKG and DKH (S3-Level, AWMF Registry Number 032/034-OL, September 2022). Part 1 with Recommendations on the Epidemiology, Screening, Diagnosis and Hereditary Factors of Endometrial Cancer, Geriatric Assessment and Supply Structures

Summary The S3-guideline on endometrial cancer, first published in April 2018, was reviewed in its entirety between April 2020 and January 2022 and updated. The review was carried out at the request of German Cancer Aid as part of the Oncology Guidelines Program and the lead coordinators were the German Society for Gynecology and Obstetrics (DGGG), the Gynecology Oncology Working Group (AGO) of the German Cancer Society (DKG) and the German Cancer Aid (DKH). The guideline update was based on a systematic search and assessment of the literature published between 2016 and 2020. All statements, recommendations and background texts were reviewed and either confirmed or amended. New statements and recommendations were included where necessary. Aim The use of evidence-based risk-adapted therapies to treat women with endometrial cancer of low risk prevents unnecessarily radical surgery and avoids non-beneficial adjuvant radiation therapy and/or chemotherapy. For women with endometrial cancer and a high risk of recurrence, the guideline defines the optimum level of radical surgery and indicates whether chemotherapy and/or adjuvant radiation therapy is necessary. This should improve the survival rates and quality of life of these patients. The S3-guideline on endometrial cancer and the quality indicators based on the guideline aim to provide the basis for the work of certified gynecological cancer centers. Methods The guideline was first compiled in 2018 in accordance with the requirements for S3-level guidelines and was updated in 2022. The update included an adaptation of the source guidelines identified using the German Instrument for Methodological Guideline Appraisal (DELBI). The update also used evidence reviews which were created based on selected literature obtained from systematic searches in selected literature databases using the PICO process. The Clinical Guidelines Service Group was tasked with carrying out a systematic search and assessment of the literature. Their results were used by interdisciplinary working groups as a basis for developing suggestions for recommendations and statements which were then modified during structured online consensus conferences and/or additionally amended online using the DELPHI process to achieve a consensus. Recommendations Part 1 of this short version of the guideline provides recommendations on epidemiology, screening, diagnosis, and hereditary factors. The epidemiology of endometrial cancer and the risk factors for developing endometrial cancer are presented. The options for screening and the methods used to diagnose endometrial cancer are outlined. Recommendations are given for the prevention, diagnosis, and therapy of hereditary forms of endometrial cancer. The use of geriatric assessment is considered and existing structures of care are presented.

The preoperative G8 geriatric screening tool independently predicts survival in older patients with endometrial cancer: results of a retrospective single-institution cohort study

PURPOSE

The aim of this retrospective study was to evaluate the prognostic impact of global health status assessment tools in elderly patients with endometrial cancer (EC) on survival.

METHODS

Preoperative frailty status was assessed by the G8 geriatric screening tool (G8 Score), Lee Schonberg prognostic index, Charlson Comorbidity index and American Society of Anesthesiologists Physical Status System in women older than 60 years with EC. Univariable and multivariable Cox-regression analyses, as well as Kaplan-Meier survival analyses were performed to determine the prognostic impact. Statistical analyses were adjusted for cancer entity-specific risk factors such as conventional histopathological tumor characteristics and relevant anamnestic life style parameters.

RESULTS

153 patients with all stages of EC who were operated at the University Medical Center Mainz between 2008 and 2019 were included. In multivariable analyses, only the G8 Score retained independent significance as a prognostic factor for disease-specific survival (DSS) (HR:4.58; 95% CI [1.35-15.51]) and overall survival (OS) (HR:2.89; 95% CI [1.31-6.39]. 92 patients (61.3%) were classified as G8-non-frail with a significantly increased DSS and OS rate compared to the 58 G8-frail patients (DSS:93.8% vs. 60.8%; p < 0.001 and OS:88.2% vs. 49.7%; p < 0.001; respectively).

CONCLUSIONS

This is the first study demonstrates the substantial clinical and prognostic impact of the G8 Score on survival in elderly women with EC. Assessing the frailty status to estimate the individual vulnerability of elderly cancer patients could be useful in preoperative decision-making to individualize treatment plans such as the surgical radicality and to improve pre- and postoperative morbidity.

Interval Debulking Surgery for Advanced Ovarian Cancer in Elderly Patients (≥70 y): Does the Age Matter?

BACKGROUND

Elderly ovarian cancer (OC) patients are more likely to be managed suboptimally, with worse clinical outcomes as a result. Strategies to decrease morbidity are lacking.Methodology: Consecutive patients with advanced stage OC (IIIC-IV) who were managed in our center between January 2016 and July 2018 were retrospectively analyzed. All patients underwent neoadjuvant chemotherapy (NACT) and interval debulking surgery (IDS) according to our institution protocol. We divided patients into two groups: Group 1 (age ≥ 70 years) and Group 2 (age < 70 years). The primary outcome of the study was assessment of peri-operative morbidity amongst two groups.

RESULTS

A total of 153 patients were referred during the study period. 114 patients underwent IDS after NACT (74.5%), 46 in Group 1 and 68 in Group 2. Elderly patients were more likely to receive more than three cycles of NACT prior to IDS compared to younger patients (39% vs. 19%, p = 0.03). Elderly patients were more frequently subjected to Cardiopulmonary Exercise Testing (CPET) as pre-operative assessment (63% vs. 27%, p = 0.002). Optimal/complete resection was achieved in all patients in Group 1 (100%) and in 97% of patients in Group 2. With the exception of higher postoperative cardiac arrhythmias in Group 1 (11% vs. 1%, p = 0.04), no significant differences in 30-day morbidity were observed. No 90-day death in both groups was registered.

CONCLUSION

Older age should not preclude clinicians from offering ultra-radical resection to patients with advanced OC after NACT. In our series, elderly patients received the same treatment with similar outcomes to the younger group. Clinicians should be encouraged to use CPET for patients' selection following NACT.

Practical brachytherapy solutions to an age-old quandary

•

Age should not be a limiting factor for brachytherapy in patients with localised cancer or for palliation in metastatic disease.

•

In tumour streams where brachytherapy forms part of the curative management, it should not be omitted in elderly patients who are medically fit for treatment.

•

Treatment decisions should factor in patient preferences, the relative merits of different therapeutic approaches and maintaining minimal impact on quality of life.

Cancer is predominantly a disease of the elderly and as population life expectancy increases, so will the incidence of malignant disease. Elderly patients often have other comorbidities and social complexities, increasing the support required to safely deliver all treatment modalities. Brachytherapy is a relatively simple technique by which radiation therapy can be delivered. It offers dosimetric advantages through a highly conformal dose distribution thereby limiting radiation exposure to normal tissues reducing toxicity. Requiring fewer hospital visits, it also offers practical and logistical advantages to the elderly population and in many cases can be performed without the need for general anaesthesia. In tumour streams where brachytherapy forms part of the curative management, it should not be omitted in elderly patients who are medically fit for treatment. In the palliative setting, brachytherapy often offers an excellent means for achieving either local tumour and/or symptom control and should be actively considered in the therapeutic armamentarium of the oncologist in this context.

Ten years of experience with endometrial cancer treatment in a single Brazilian institution: Patient characteristics and outcomes

Few reports have described the clinical and prognostic characteristics of endometrial cancer, which is increasing worldwide, in large patient series in Brazil. Our objective was to analyze the clinicopathological characteristics, prognostic factors, and outcomes of patients with endometrial cancer treated and followed at a tertiary Brazilian institution over a 10-year period.This retrospective study included 703 patients diagnosed with endometrial cancer who were treated at a public academic tertiary hospital between 2008 and 2018. The following parameters were analyzed: age at diagnosis, race, body mass index, serum CA125 level before treatment; histological type and grade, and surgical stage. Outcomes were reported relative to histological type, surgical staging, serum CA125, lymph-vascular space involvement (LVSI), and lymph-node metastasis.

The median patient age at diagnosis was 63 (range, 27–93) years (6.4% were <50 years). Minimally invasive surgeries were performed in 523 patients (74.4%). Regarding histological grade, 468 patients (66.5%) had low-grade endometrioid histology and 449 patients (63.9%) had stage I tumors. Tumors exceeded 2.0 cm in 601 patients (85.5%). Lymphadenectomy was performed in 551 cases (78.4%). LVSI was present in 208 of the patients’ tumors (29.5%). Ninety-three patients (13.2%) had recurrent tumors and 97 (13.7%) died from their malignant disease. The robust prognostic value of FIGO stage and lymph node status were confirmed. Other important survival predictors were histological grade and LVSI [overall survival: hazard ratio (HR) = 3.75, p < 0.001 and HR = 2.01, p = 0.001; recurrence: HR = 2.49, p = 0.004 and HR = 3.22, p = 0.001, respectively). Disease-free (p = 0.087) and overall survival (p = 0.368) did not differ significantly between patients with stage II and III disease. These results indicate that prognostic role of cervical involvement should be explored further. This study reports the characteristics and outcomes of endometrial cancer in a large population from a single institution, with systematic surgical staging, a predominance of minimally invasive procedures, and well-documented outcomes. Prognostic factors in the present study population were generally similar to those in other countries, though our patients’ tumors were larger than in studies elsewhere due to later diagnosis. Our unexpected finding of similar prognoses of stage II and III patients raises questions about the prognostic value of cervical involvement and possible differences between carcinomas originating in the lower uterine segment versus those originating in the body and fundus. The present findings can be used to guide public policies aimed at improving the diagnosis and treatment of endometrial cancer in Brazil and other similar countries.

Identification of key genes and pathways between type I and type II endometrial cancer using bioinformatics analysis

Endometrial carcinoma (EC) is a common malignant neoplasm of the female reproductive tract. The malignant degree of type II EC is much greater than that of type I EC, usually presenting with a high recurrence rate and a poor prognosis. Therefore, the present study aimed to examine the principal genes associated with the degree of differentiation in type I and type II EC and reveal their potential mechanisms. Differentially expressed genes (DEGs) were selected from the gene expression profiles derived from The Cancer Genome Atlas. Gene Ontology and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analyses were conducted. In the present study, the KEGG pathway enrichment analysis revealed that 5,962 upregulated DEGs were significantly enriched in the ‘p53 signaling pathway’ and involved in ‘lysine degradation’. In addition, 3,709 downregulated DEGs were enriched in ‘pathways in cancer’, as well as ‘tight junction regulation’, the ‘cell cycle’ and the ‘Wnt signaling pathway’. The 13 top hub genes MAPK1, PHLPP1, ESR1, MDM2, CDKN2A, CDKN1A, AURKA, BCL2L1, POLQ, PIK3R3, RHOQ, EIF4E and LATS2 were identified via the protein-protein interaction network. Furthermore, the OncoPrint algorithm from cBioPortal declared that 25% of EC cases carried genetic alterations. The altered DEGs (MAPK1, MDM2, AURKA, EIF4E and LATS2) may be involved in tumor differentiation and may be valuable diagnostic biomarkers. In conclusion, a number of principal genes were identified in the present study that may be determinants of poorly differentiated type II EC carcinogenesis, which may contribute to future research into potential molecular mechanisms. In addition, these genes may help identify candidate biomarkers and novel therapeutic targets for type II EC.
