Survival of Women with Advanced Stage Cervical Cancer:Neo-Adjuvant Chemotherapy Followed by Radiotherapy and Hyperthermia versus Chemoradiotherapy
Aim: To investigate and compare overall survival (OS), disease-free survival (DFS) and toxicity of women who underwent either chemoradiotherapy with or without prior lymph node debulking or upfront chemotherapy followed by radiotherapy and hyperthermia (triple therapy) for locally advanced cervical cancer (LACC) to identify a potential role for triple therapy. Methods: Women with histologically proven LACC and with International Federation of Gynecology and Obstetrics (FIGO) 2009 stage IB2 and IIA2 to IVA were included. Cox regression analyses were used for calculating hazard ratios and to adjust for confounding variables. A multivariable logistic regression analysis was used to examine the influence of covariates on toxicity. Results: A total of 370 patients were included of whom 58% (n = 213) received chemoradiotherapy (CRT), 18% (n = 66) received node-debulking followed by chemoradiotherapy (LND-CRT) and 25% (n = 91) received triple therapy (TT). Five-year OS was comparable between the three treatment groups, with 53% (95% confidence interval 46–59%) in the CRT group, 45% (33–56%) in the LND-CRT group and 53% (40–64%) in the TT group (p = 0.472). In the adjusted analysis, 5-year OS and DFS were comparable between the three treatment groups. No chemotherapy-related differences in toxicity were observed. Conclusion: This study suggests that the toxicity and survival of TT is similar to CRT or LND-CRT.</p

Phenotype-guided targeted therapy based on functional signal transduction pathway activity in recurrent ovarian cancer patients:The STAPOVER study protocol
Objective: Ovarian cancer is the fifth cause of cancer-related death among women. The benefit of targeted therapy for ovarian cancer patients is limited even if treatment is stratified by molecular signature. There remains a high unmet need for alternative diagnostics that better predict targeted therapy, as current diagnostics are generally inaccurate predictors. Quantitative assessment of functional signal transduction pathway (STP) activity from mRNA measurements of target genes is an alternative approach. Therefore, we aim to identify aberrantly activated STPs in tumour tissue of patients with recurrent ovarian cancer and start phenotype-guided targeted therapy to improve survival without compromising quality of life. Study design: Patients with recurrent ovarian cancer and either 1) have platinum-resistant disease, 2) refrain from standard therapy or 3) are asymptomatic and not yet eligible for standard therapy will be included in this multi-centre prospective cohort study with multiple stepwise executed treatment arms. Targeted therapy will be available for patients with aberrantly high functional activity of the oestrogen receptor, androgen receptor, phosphoinositide 3-kinase or Hedgehog STP. The primary endpoint of this study is the progression-free survival (PFS) ratio (PFS2/PFS1 ratio) according to RECIST 1.1 determined by the PFS on matched targeted therapy (PFS2) compared to PFS on prior therapy (PFS1). Secondary endpoints include among others best overall response, overall survival, side effects, health-related quality of life and cost-effectiveness. Conclusion: The results of this study will show the clinical applicability of STP activity in selecting recurrent ovarian cancer patients for effective therapies.</p
Implementation of laparoscopic hysterectomy for endometrial cancer over the past decade
Background: Laparoscopic hysterectomy (LH) for the treatment of early-stage endometrial carcinoma/cancer (EC) has demonstrated to be safe in several randomized controlled trials. Yet, data on implementation of LH in clinical practice are limited. In the present study, implementation of LH for EC was evaluated in a large oncology network in the Netherlands. Results: Retrospectively, a total of 556 EC patients with FIGO stage I-II were registered in the selected years. The proportion of LH gradually increased from 11% in 2006 to 85% in 2015. LH was more often performed in patients with low-grade EC and was not related to the studied patient characteristics. The introduction of TLH was frequently preceded by LAVH. Patients treated in teaching hospitals were more likely to undergo a LH compared to patients in non-teaching hospitals. The conversion rate was 7.7%, and the overall complication rates between LH and AH were comparable, but less postoperative complications in LH. Conclusions: Implementation of laparoscopic hysterectomy for early-stage EC increased from 11 to 85% in 10Â years. Implementation of TLH was often preceded by LAVH and was faster in teaching hospitals
Long-Term Morbidity and Health After Early Menopause Due to Oophorectomy in Women at Increased Risk of Ovarian Cancer:Protocol for a Nationwide Cross-Sectional Study With Prospective Follow-Up (HARMOny Study)
Background: BRCA1/2 mutation carriers are recommended to undergo risk-reducing salpingo-oophorectomy (RRSO) at 35 to 45 years of age. RRSO substantially decreases ovarian cancer risk, but at the cost of immediate menopause. Knowledge about the potential adverse effects of premenopausal RRSO, such as increased risk of cardiovascular disease, osteoporosis, cognitive dysfunction, and reduced health-related quality of life (HRQoL), is limited. Objective: The aim of this study is to assess the long-term health effects of premenopausal RRSO on cardiovascular disease, bone health, cognitive functioning, urological complaints, sexual functioning, and HRQoL in women with high familial risk of breast or ovarian cancer. Methods: We will conduct a multicenter cross-sectional study with prospective follow-up, nested in a nationwide cohort of women at high familial risk of breast or ovarian cancer. A total of 500 women who have undergone RRSO before 45 years of age, with a follow-up period of at least 10 years, will be compared with 250 women (frequency matched on current age) who have not undergone RRSO or who have undergone RRSO at over 55 years of age. Participants will complete an online questionnaire on lifestyle, medical history, cardiovascular risk factors, osteoporosis, cognitive function, urological complaints, and HRQoL. A full cardiovascular assessment and assessment of bone mineral density will be performed. Blood samples will be obtained for marker analysis. Cognitive functioning will be assessed objectively with an online neuropsychological test battery. Results: This study was approved by the institutional review board in July 2018. In February 2019, we included our first participant. As of November 2020, we had enrolled 364 participants in our study. Conclusions: Knowledge from this study will contribute to counseling women with a high familial risk of breast/ovarian cancer about the long-term health effects of premenopausal RRSO. The results can also be used to offer health recommendations after RRSO
Tailoring radicality in early cervical cancer: how far can we go?
Today, the patient who is diagnosed with early cervical cancer is offered a variety of treatments apart from standard therapy. Patients can be treated with a less radical hysterectomy (RH) regarding parametrectomy, a trachelectomy either vaginal or abdominal, and this can be performed through a minimal invasive or open procedure. All this in combination with nerve sparing and/or sentinel node technique. Level 1 evidence for the oncological safety of all these modifications is only available from 3 randomized controlled trials (RCTs). Two RCTs on more or less radical parametrectomy both showed that oncological safety was not compromised by doing less radical surgery. Because of the heterogeneity of the patient population and the high frequency of adjuvant radiotherapy, the true impact of surgical radicality cannot be assessed. Regarding the issue of oncological safety of fertility sparing treatments, case-control and retrospective case series suggest that trachelectomy is safe as long as the tumor diameter does not exceed 2 cm. Recently, both a RCT and 2 case-control studies showed a survival benefit for open surgery compared to minimally invasive surgery, whereas many previous case-control and retrospective case series on this subject did not show impaired oncological safety. In a case-control study the survival benefit for open surgery was restricted to the group of patients with a tumor diameter more than 2 cm. Although modifications of the traditional open RH seem safe for tumors with a diameter less than 2 cm, ongoing prospective RCTs and observational studies should give the final answer
More attention is needed for the corrigendum to the revised FIGO staging for carcinoma of the cervix uteri
Is less more in the surgical treatment of early-stage cervical cancer?
PURPOSE OF REVIEW: This article discusses recent developments towards less radical surgical treatment for early-stage cervical cancer. RECENT FINDINGS: Surgery is the standard treatment for early-stage cervical cancer. In the last decades, new treatment strategies have been developed aiming to reduce morbidity, without hampering oncological safety. We provide an update of the latest knowledge on safety and morbidity following less radical surgical procedures in early-stage cervical cancer. In cervical cancer with a tumour size of 2 cm or less, radical surgery (simple hysterectomy or fertility-sparing conisation) may be a well tolerated option. For patients with larger lesions (>2 cm) and wishing to preserve fertility, administration of neoadjuvant chemotherapy followed by less extensive surgery appears to be a feasible and well tolerated alternative to abdominal trachelectomy. With regard to lymph node assessment, increasing evidence shows the feasibility of the sentinel lymph node procedure instead of full pelvic lymphadenectomy. Prospective trials reporting on oncological safety are awaited.It is important to exercise caution when new surgical strategies are introduced. Despite promising retrospective data, prospective randomized studies may present unexpected results, for instance, minimally invasive radical hysterectomy showed inferior results compared to laparotomy. SUMMARY: There is a shift towards less radical treatment for early-stage cervical cancer. This review explores whether and when less is really more
The risk of lymph node metastasis in the new FIGO 2018 stage IA cervical cancer with >7 mm diameter
OBJECTIVE: In the 2018 FIGO staging system, cervical cancers with ≤5 mm depth of invasion (DOI) and a diameter of >7 mm, first classified as stage IB, are classified as stage IA. In this group, it is unclear what the risk of lymph node metastasis (LNM) is. This retrospective cohort study aims to determine the incidence of LNM and to study the association between disease-related characteristics and LNM.METHODS: Women diagnosed with FIGO 2009 IB cervical cancer, with ≤5 mm DOI and a diameter >7 mm, treated with a radical hysterectomy and pelvic lymphadenectomy between 1985 and 2020 were selected from the databases of the Amsterdam University Medical Center and the University Medical Center Groningen. The specimens of patients with LNM were revised by expert pathologists. The incidence of LNM was calculated. The associations between LNM and DOI, diameter, histological type, clinical visibility and lymphovascular space invasion (LVSI) were evaluated by calculating odds ratios using logistic regression.RESULTS: Of the 389 patients included, 10 had pathologically confirmed LNM (2.6%, 95% confidence interval=1.3%-4.5%). In case of LVSI, univariate analysis showed an increased risk of LNM (p=0.003 and p=0.012, respectively). No difference in LNM was found between lesions diagnosed by microscopy and clinically visible lesions. No LNM were found in patients without LVSI and a DOI of ≤3 mm.CONCLUSION: For patients with stage IA cervical cancer with a diameter >7 mm, we recommend considering a pelvic lymph node assessment in case of DOI >3 mm and/or presence of LVSI.</p
Analysis of isolated loco-regional recurrence rate in intermediate risk early cervical cancer after a type C2 radical hysterectomy without adjuvant radiotherapy
Background The efficacy of adjuvant radiotherapy in patients with intermediate risk early cervical cancer after radical hysterectomy is still under debate. Most guidelines recommend adjuvant radiotherapy, whereas others consider observation a viable option. Objective To investigate if patients with intermediate risk factors for cervical cancer who underwent radical hysterectomy may benefit from adjuvant radiotherapy. Methods Consecutive patients with tumor confined to the cervix and intermediate risk factors (according to Sedlis), treated between January 1982 and December 2014 who were observed after a type C2 radical hysterectomy formed the basis for this study. The frequency of recurrences, specifically isolated loco-regional recurrences, and the risk of death from recurrences, were analyzed. Data were analyzed using SPSS, version 23.0 for Windows Results A total of 161 patients were included in the analysis. Median age was 40 (range 20-76). Stages IB1 and IB2 were seen in 87 (54%) and 74 patients (46%), respectively. Squamous cell and non-squamous histology was seen in 114 (70.8%) and 47 patients (29.2%), respectively. Of the 161 patients, 25 (15.5%) had recurrent disease, of whom nine had an isolated loco-regional recurrence (5.6%). Median time to recurrence for isolated loco-regional recurrences was 28 months (range 9-151). Treatment for an isolated loco-regional recurrence was radiotherapy (n = 4) and chemoradiotherapy (n = 5). Four patients (2.5%) died from disease as a result of an isolated loco-regional recurrence. Actuarial disease-specific survival was 93.0% for the total group. No variables were found that predicted an isolated loco-regional recurrence. Discussion The mortality from isolated loco-regional recurrence in patients with intermediate risk factors for cervical cancer who underwent only radical hysterectomy type C2 was 2.5%. Further studies should compare outcomes between patients who undergo a type C2 radical hysterectomy without adjuvant radiotherapy with those undergoing a less radical hysterectomy but with adjuvant radiotherapy
