Carboplatin, methotrexate and 5-fluorouracil in combination with medroxyprogesterone acetate (JMF-M) in the treatment of advanced or recurrent endometrial carcinoma: A Hellenic cooperative oncology group study

Novel polymer-based system for intrauterine delivery of everolimus for anti-cancer applications

Non-surgical treatment options for low-grade endometrial cancer and precancerous lesions are a critical unmet need for women who wish to preserve fertility or are unable to undergo hysterectomy. The PI3K/AKT/mTOR pathway is frequently activated in endometrial cancers and has been associated with resistance to endocrine therapy, making it a compelling target for early stage disease. Oral everolimus, an inhibitor against mTORC1, has shown clinical benefit in advanced or recurrent disease but has severe adverse effects that may lead to treatment interruption or dose reduction. To overcome this, we developed a polymer-based intrauterine delivery system to achieve persistent, local delivery of everolimus without systemic exposure. In vivo studies, using a rat model, showed that a poly(propylene fumarate)-based rod loaded with everolimus achieved everolimus delivery to the endometrium with levels similar to oral administration, but with limited systemic exposure and up to 84 days of release. Biological activity of everolimus delivered with this system was confirmed, measured by reduced lumen epithelial cell height and PI3K pathway biomarkers. This study shows a promising new delivery approach for anti-cancer drugs for non-surgical treatment of low-grade endometrial cancer.

Fertility Sparing Treatment in Patients With Early Stage Endometrial Cancer, Using a Combination of Surgery and GnRH Agonist: A Monocentric Retrospective Study and Review of the Literature

Objectives: To evaluate the efficacy and safety of gonadotropin-releasing hormone (GnRH) agonist after endometrial resection in women suffering early stage endometrial carcinoma (EC) and/or endometrial intra-epithelial neoplasia (EIN). Design: A retrospective review of clinical files between January 1999 and December 2016. Setting: University hospital. Patients: Eighteen women younger than 41 years with grade 1 endometrial carcinoma (G1EC) and/or Endometrial intra-epithelial neoplasia (EIN).

INTERVENTIONS

All patients received GnRH agonist for 3 months after an endometrial resection combined with a laparoscopy to exclude concomitant ovarian tumor and/or other extra-uterine disease. The patient underwent a follow-up of 3 months interval with endometrial sampling by hysteroscopy. Main Outcome Measure(s): The recurrence rate and the pregnancy rate after fertility sparing treatment. Results: We identified 9 patients with EIN (50%), 7 patients with G1EC (38.9%), 1 with combined histology (5.5%), and 1 with G2EC (5.5%). After a median follow-up of 40.7 months, 12 patients conserved their uterus (66.7%), and 8 (53.3%) patients were pregnant with a total of 14 pregnancies among those who tried to become pregnant. We observed a complete response rate in 12 patients (66.7%) but 3 of these patients relapsed (25%). We also found a stable disease in 6 patients (33.3%). Conclusions: Compared with other fertility sparing treatments, GnRH agonist after surgery is an effective fertility-sparing strategy for women with EIN and/or G1EC. We recommend hysterectomy once a family has been completed even if the literature does not clearly lead to radical surgery.

Endometrial adenocarcinoma in a 27-year-old woman

BACKGROUND

Endometrial adenocarcinoma usually occurs after menopause, but in 2%-14% of cases, it occurs in young patients (less than 40 years of age) who are eager to preserve their fertility. Its treatment includes hysterectomy, bilateral salpingo-oophorectomy and pelvic lymphadenectomy, and, in some cases, radiation therapy.

AIM

To describe a case of endometrial adenocarcinoma occurring in a young woman and to undertake a literature review of risk factors and therapeutic options proposed for young women wishing to preserve their fertility.

CASE

We report a case of endometrial cancer in a 27-year-old woman treated for resistant menorrhagia and cared for in our department as well as in the Salah Azaiez Institute.

CONCLUSION

Endometrial adenocarcinoma rarely occurs in young women. In such cases, other therapeutic options can be proposed: progesterone therapy and LH-RH (Luteinzing-Hormone-Releasing-Hormone) agonists therapy in order to preserve fertility in younger patients.

Treatment for advanced and recurrent endometrial carcinoma: combined modalities

Women with recurrent or advanced endometrial cancer constitute a heterogeneous group of patients. Depending on previous treatment, women with recurrent endometrial cancer may be appropriate candidates for surgery, radiation therapy, hormonal therapy, or chemotherapy. Women with advanced stage disease at presentation may also be appropriate candidates for systemic and local therapies. We review the treatment options available to treat recurrent and locally advanced endometrial cancer. Treatment choice depends largely on the localization of disease, the patient's performance status and previous treatment history, as well the tumor's hormonal receptor status. Radiation therapy is appropriate for isolated vaginal recurrences in patients with no previous history of radiation therapy. Patients with recurrent low-grade tumors overexpressing estrogen and progesterone receptors may be treated with progestin therapy. Systemic therapy is appropriate for patients with disseminate recurrences or advanced stage disease at presentation, or for those with receptor-negative tumors. We review all these different treatment strategies available to patients with advanced or recurrent endometrial cancer.

Endometrial cancer: what is new in adjuvant and molecularly targeted therapy?

Endometrial cancer is the most common gynaecological cancer in western countries. Radiotherapy remains the mainstay of postoperative management, but accumulating data show that adjuvant chemotherapy may display promising results after staging surgery. The prognosis of patients with metastatic disease remains disappointing with only one-year survival. Progestins represent an effective option, especially for those patients with low-grade estrogen and/or progesterone receptor positive disease. Chemotherapy using the combination of paclitaxel, doxorubicin, and cisplatin is beneficial for patients with advanced or metastatic disease after staging surgery and potentially for patients with early-stage disease and high-risk factors. Toxicity is a point in question; however, the combination of paclitaxel with carboplatin may diminish these concerns. In women with multiple medical comorbidities, single-agent chemotherapy may be better tolerated with acceptable results. Our increased knowledge of the molecular aspects of endometrial cancer biology has paved the way for clinical research to develop novel targeted antineoplastic agents (everolimus, temsirolimus, gefitinib, erlotinib, cetuximab, trastuzumab, bevacizumab, sorafenib) as more effective and less toxic options. Continued investigation into the molecular pathways of endometrial cancer development and progression will increase our knowledge of this disease leading to the discovery of novel, superior agents.

Chemotherapy for advanced, recurrent or metastatic endometrial cancer: a systematic review of Cochrane collaboration

BACKGROUND

Cytotoxic chemotherapy has a limited place in the management of advanced or recurrent endometrial cancer. Commonly used agents include cisplatin and doxorubicin, but the side-effect profile may be unacceptable for many patients. The feasibility of administration of combination chemotherapy is limited in many patients on account of significant co-morbidity. While early-stage endometrial adenocarcinoma is a common gynaecological cancer with a favourable prognosis, advanced or recurrent disease presents a difficult management problem. The platinum and anthracycline compounds have been widely used for many years, but their impact on progression-free survival (PFS) and overall survival (OS) is not clear. This systematic review aimed to evaluate both the benefits and adverse effects of cytotoxic chemotherapy in these women.

PATIENTS AND METHODS

We carried out systematic searches for randomised controlled trials (RCTs) comparing chemotherapy with another intervention. Data were extracted from trial reports or supplied by investigators. Where possible, hazard ratios (HRs) were calculated for OS and PFS and odds ratios (ORs) were calculated for acute toxicity. The impact of more versus less intensive chemotherapy on OS, PFS and acute toxicity was assessed in a meta-analysis.

RESULTS

Eleven eligible RCTs were identified that recruited 2288 patients. A meta-analysis of six of these trials found that PFS [HR = 0.80, 95% confidence interval (CI) 0.71-0.90; P = 0.004], but not OS (HR = 0.90, 95% CI 0.80-1.03; P = 0.12), was significantly improved when more intensive chemotherapy was compared with less intensive chemotherapy. OS was improved when doxorubicin, cisplatin and other drugs were compared with doxorubicin and cisplatin. Toxicity was generally higher with more chemotherapy. There was insufficient evidence to assess the effect of chemotherapy on symptom control or quality of life (QoL). Platinums, anthracyclines and taxanes were the most studied in phase II trials and combinations gave the best responses, but patient selection and pre-treatment was very variable.

CONCLUSIONS

More intense combination chemotherapy significantly improves the disease-free survival and the data indicate a modest improvement in OS. The addition of anthracyclines (e.g. doxorubicin) or the taxanes [e.g. paclitaxel (Taxol)] to cisplatin increases the response rate. More intensive regimens are associated with the gain in survival. However, grade 3 and 4 myelosuppression and gastrointestinal toxicity are also increased. Future developments are likely to exploit specific molecular characteristics of endometrial cancers, including their hormone dependence, growth factor target overexpression and PTEN loss. While no one drug or regimen offers a clear benefit for women with advanced endometrial cancer, platinum drugs, anthracyclines and paclitaxel seem the most promising agents. Future trials should address the impact of such agents on QoL and symptom control in addition to survival. Chemotherapy and endocrine therapy need to be compared directly in an RCT.

Radioterapia adjuvante no tratamento do câncer de endométrio: experiência com a associação de radio-terapia externa e braquiterapia de alta taxa de dose

OBJETIVO: Analisar, retrospectivamente, os resultados da radioterapia externa (RT) combinada a braquiterapia de alta taxa de dose (BATD), adjuvantes à cirurgia para o carcinoma de endométrio. MATERIAIS E MÉTODOS: Avaliamos 141 pacientes tratados com RT e BATD adjuvantes à cirurgia, no período de janeiro de 1993 a janeiro de 2001. RT pélvica foi realizada com dose mediana de 45 Gy, e BATD realizada na dose mediana de 24 Gy, em quatro inserções semanais de 6 Gy. A idade mediana das pacientes foi de 63 anos e a distribuição por estádio clínico (EC) foi: EC I (FIGO), 52,4%; EC II, 13,5%; EC III, 29,8%; EC IV, 4,3%. RESULTADOS: Com seguimento mediano de 53,7 meses, a sobrevida livre de doença (SLD) em cinco anos foi: EC I, 88,0%; EC II, 70,8%; EC III, 55,1%; EC IV, 50,0% (p = 0,0003). A sobrevida global em cinco anos foi: EC I, 79,6%; EC II, 74,0%; EC III, 53,6%; EC IV, 100,0% (p = 0,0062). Fatores que influíram na SLD foram grau histológico e histologia seropapilífera. Dos 33 casos que apresentaram recidiva da doença, em 13 (9,2%) esta ocorreu na pelve, vagina ou cúpula vaginal. RT + BATD do fundo vaginal permitiram o controle da doença em 90,8% dos casos. CONCLUSÃO: A RT exerce papel fundamental no controle loco-regional do câncer de endométrio e permite excelentes taxas de cura nos estádios iniciais. Para os estádios mais avançados, a falha terapêutica tende a ser a distância, sugerindo a necessidade de complementação terapêutica sistêmica, com introdução de novas modalidades de tratamento, em particular a quimioterapia.

Chemotherapy for advanced, recurrent or metastatic endometrial carcinoma

BACKGROUND

Endometrial adenocarcinoma is a common gynaecological cancer, but a comparatively small proportion of patients present with or develop recurrent or advanced disease. Progestogens are widely used, with little evidence of their efficacy. Co-morbidity including obesity and cardiac disease and concerns over toxicity have prevented more extensive studies of cytotoxic chemotherapy, although there are a number of active agents.

OBJECTIVES

To assess any benefits or adverse effects of cytotoxic chemotherapy in women with advanced, recurrent or metastatic endometrial adenocarcinoma.

SEARCH STRATEGY

The major medical literature databases were searched for all known randomised controlled trials (RCTs), as were trials registers and reference lists of relevant publications.

SELECTION CRITERIA

RCTs comparing chemotherapy versus another intervention (including different chemotherapy) in advanced disease were considered. Trials of adjuvant treatment or for sarcomatous tumours were excluded.

DATA COLLECTION AND ANALYSIS

Data were extracted from the papers by reviewers and authors of included studies contacted for further information.

MAIN RESULTS

Eleven eligible trials were identified which entered 2288 patients between 1974 and 2000. A meta-analysis of the 6 trials comparing more with less chemotherapy with combination was possible and included 1135 patients. Progression-free survival (PFS) was significantly improved (Hazard Ratio (HR) = 0.80, 95% Confidence Interval (CI) 0.71 to 0.90, p = 0.004), but there was only a trend toward improved survival (HR = 0.90, 95% CI 0.80 to 1.03). Toxicity was in general higher with the combination chemotherapy regimens. Only one trial showed a significant survival benefit from the addition of paclitaxel to combination chemotherapy, but this was at the expense of increased toxicity. There was insufficient evidence to assess whether there was any benefit from cytotoxic chemotherapy in terms of symptom control or quality of life (QOL) compared with best supportive care. There were no comparative trials of chemotherapy with endocrine therapy

AUTHORS' CONCLUSIONS

The optimum cytotoxic drug regimen for advanced endometrial adenocarcinoma has still to be defined although our review suggests that it may contain paclitaxel or platinum. These mainly North American and European trial populations represent a highly selected subgroup of the 10, 000 women dying annually from this disease. Future trials should include measures of QOL and symptom control in addition to PFS and overall survival (OS). They should should also consider comparison of of endocrine therapy and cytotoxic chemotherapy in patients with no prior drug therapy. Stratification of patients should take into account other prognostic factors including co-morbidity and prior radiation treatment.

Conservative treatment may be beneficial for young women with atypical endometrial hyperplasia or endometrial adenocarcinoma

OBJECTIVE

To evaluate whether an alternative treatment to radical hysterectomy exists for young women with endometrial adenocarcinoma.

DESIGN

A review of the literature (70 articles) plus personal results.

SETTING

University hospital.

PATIENT(S)

Women with atypical endometrial hyperplasia or adenocarcinoma.

MAIN OUTCOME MEASURE(S)

The recurrence rate and the pregnancy rate after conservative therapy.

CONCLUSION(S)

Conservative treatment of well-differentiated stage I endometrial adenocarcinoma can be considered in young patients, with close surveillance to diagnose any possible recurrence.

Progestins and endometrial cancer

Premenopausal women--especially young women--with endometrial cancer stage I may be treated successfully with progestins alone as primary therapy to preserve their child-bearing potential. There is some indication that progestins could be used in neoadjuvant fashion. Individualization of adjuvant treatment with radiation or progestins and in combination seems possible. Progestins have an established place in the palliative treatment of women with advanced cancer. In addition, progestins can be used in advanced and/or recurrent endometrial cancer in combination with chemotherapy and tamoxifen.

Conservative therapy for adenocarcinoma and atypical endometrial hyperplasia of the endometrium in young women: central pathologic review and treatment outcome

Thirty-nine patients with endometrioid adenocarcinoma (EA) and atypical hyperplasia (AH) of the endometrium who received conservative treatment to preserve fertility were collected from member institutions of the Japan Gynecologic Oncology Study Group. Twenty-nine and ten were originally diagnosed with EA without myometrial invasion and AH, respectively. We performed a central pathological review to make definite diagnoses, and the diagnosis of EA in 29 cases was changed to AH in ten, complex hyperplasia in three and atypical polypoid adenomyoma in three, and AH in ten was changed to EA in one and simple hyperplasia in one. Nine of 12 women (75%) with EA and 15 of 18 women (83%) with AH had an initial response to medroxyprogesterone acetate (MPA) treatment. Two of nine responders with EA later developed relapse, and one of them had metastasis to the left obturator lymph node. Two became pregnant, and one delivered one full-term infant. One of the responders with AH had a relapse in the endometrium. Five became pregnant, and four delivered four normal infants. The young women with endometrial carcinoma localized in the endometrium who wish to preserve fertility may be treated as successfully with MPA as those with AH.

Is there any place for cytotoxic chemotherapy in endometrial cancer?

Cytotoxic chemotherapy has an established role in the treatment of many solid tumours that are considered to be incurable with any modern treatment method. Such treatment may result in an improvement in quality of life without influencing overall survival. In this chapter the evidence to support the use of chemotherapy in patients with advanced or recurrent endometrial adenocarcinoma is reviewed. The most effective single agent and combination treatments are outlined. Although evidence from randomized trials is limited, combination chemotherapy can lead to response rates of over 40% in patients with advanced disease. The role of chemotherapy as adjuvant treatment in patients with early-stage disease is less well defined and this treatment is not recommended outside a clinical trial. The role of chemotherapy for treatment of the aggressive histological variant, uterine papillary serous carcinoma is also discussed.

Novel strategies for systemic treatment of endometrial cancer

The median survival of women with advanced or recurrent endometrial cancer is less than one year. Of the women with early stage endometrial cancer and poor prognostic factors like high grade or deep myometrial invasion, 40% will recur. Over the last decade, incredible strides have been taken in evaluating systemic therapy for this disease, however, survival rates remain poor. Progestin therapy offers a 10 - 20% response rate and survival of less than one year. Progestins are most effective in women with well-differentiated tumours and long disease-free interval. There is no role for adjuvant progestin therapy in early stage disease. Single-agent chemotherapy with most activity include ifosfamide, cisplatin/carboplatin, doxorubicin and paclitaxel. Combination chemotherapy provides a response rate of 40 - 60%, however, median survival is still less than a year. New areas of research include the identification and evaluation of new active endocrine therapies (i.e., LY-353381.HCl and letrozole), chemotherapeutics (i.e., paclitaxel), evaluating chemotherapeutic agents in combination (i.e., paclitaxel, doxorubicin and platinum), in addition to radiation or instead of radiation. New avenues under development involve the specific molecules and pathways responsible for the initiation and growth of endometrial carcinoma (i.e., Herceptintrade mark). Exciting developments in the understanding of the molecules involved in tumour development and metastasis will allow the development of specific and selective inhibitors.
