High Rate of Endometrial Hyperplasia in Renal Transplanted Women

Endometrial cancer in a renal transplant recipient: A case report

As the most effective treatment for end-stage renal diseases, renal transplantation can improve the quality of life of patients and prolong the survival time. However, during the prolonged survival time, malignancy has become one of the main causes of death of recipients, which vary geographically. Tumors in the digestive system and urothelial tumors have been highly reported in Asia. In general, the gynecological malignant tumors have been rarely reported, especially the endometrial carcinoma. Herein, a 63-year-old female renal transplant recipient diagnosed with endometrial carcinoma (15 years after transplantation) was reported. The patient had suffered irregular postmenopausal bleeding for a short time before hospitalization. She underwent abdominal hysterectomy, bilateral salpingo-oophorectomy, right pelvic lymphadenectomy, right para-aortic lymphadenectomy and omental excision. Postoperative pathology showed ovarian and pelvic lymph node metastasis and pathological stage IIIC. After six courses of chemotherapy with paclitaxel 270 mg + carboplatin 500 mg, the patient’s renal function was normal. During the third cycle of chemotherapy, the patient suffered a third-degree bone marrow suppression and returned to normal soon when treated with the recombinant human granulocyte stimulating factor. In conclusion, early screening of gynecologic tumors is important for female patients after renal transplantation, which has a positive significance for the prognosis improvement.

Successful multidisciplinary treatment of uterine serous carcinoma in a patient who had previously undergone renal transplantation

OBJECTIVE

Renal transplantation is a risk factor for premalignant and malignant changes of the endometrium. Thus, prompt and aggressive treatment of postoperative complications remains a major issue. We report the case of an asymptomatic postmenopausal woman with a history of renal transplantation who underwent surgery for uterine serous carcinoma (USC).

CASE REPORT

An asymptomatic 59-year-old woman who had undergone renal transplantation presented with elevated serum CA-125 levels. Cancer screening revealed uterine serous carcinoma, for which she underwent total hysterectomy and bilateral salpingo-oophorectomy. Unfortunately, the postoperative course was complicated by cardiogenic shock and decompensated heart failure. The complexities of the cardiac problems and renal transplantation required a multidisciplinary approach involving different specialists. She was successfully discharged 48 days after the surgery.

CONCLUSION

Gynecologic cancer screening in asymptomatic postmenopausal women after renal transplantation is warranted. If postoperative complications occur in this population, a multidisciplinary approach is recommended.

New concepts for an old problem: the diagnosis of endometrial hyperplasia

BACKGROUND

Endometrial hyperplasia (EH) is a uterine pathology representing a spectrum of morphological endometrial alterations. It is predominantly characterized by an increase in the endometrial gland-to-stroma ratio when compared to normal proliferative endometrium. The clinical significance of EH lies in the associated risk of progression to endometrioid endometrial cancer (EC) and 'atypical' forms of EH are regarded as premalignant lesions. Traditional histopathological classification systems for EH exhibit wide and varying degrees of diagnostic reproducibility and, as a consequence, standardized patient management can be challenging.

OBJECTIVE AND RATIONALE

EC is the most common gynaecological malignancy in developed countries. The incidence of EC is rising, with alarming increases described in the 40-44-year-old age group. This review appraises the current EH classification systems used to stratify women at risk of malignant progression to EC. In addition, we summarize the evidence base regarding the use of immunohistochemical biomarkers for EH and discuss an emerging role for genomic analysis.

SEARCH METHODS

PubMed, Medline and the Cochrane Database were searched for original peer-reviewed primary and review articles, from January 2000 to January 2016. The following search terms were used: 'endometrial hyperplasia', 'endometrial intraepithelial neoplasia', 'atypical hyperplasia', 'complex atypical hyperplasia', 'biomarker', 'immunohistochemistry', 'progression', 'genomic', 'classification' and 'stratification'.

OUTCOMES

Recent changes to EH classification reflect our current understanding of the genesis of endometrioid ECs. The concept of endometrial intraepithelial neoplasia (EIN) as a mutationally activated, monoclonal pre-malignancy represents a fundamental shift from the previously held notion that unopposed oestrogenic stimulation causes ever-increasing hyperplastic proliferation, with accumulating cytological atypia that imperceptibly leads to the development of endometrioid EC. Our review highlights several key biomarker candidates that have been described as both diagnostic tools for EH and markers of progression to EC. We propose that, moving forwards, a 'panel' approach of combinations of the immunohistochemical biomarkers described in this review may be more informative since no single candidate can currently fill the entire role.

WIDER IMPLICATIONS

EC has historically been considered a predominantly postmenopausal disease. Owing in part to the current unprecedented rates of obesity, we are starting to see signs of a shift towards a rising incidence of EC amongst pre- and peri-menopausal woman. This creates unique challenges both diagnostically and therapeutically. Furthering our understanding of the premalignant stages of EC development will allow us to pursue earlier diagnosis and facilitate appropriate stratification of women at risk of developing EC, permitting timely and appropriate therapeutic interventions.

Menopause in women with chronic immunosuppressive treatment - how to help those patients

Women after organ transplantation with chronic immunosuppressive therapy or after bone marrow transplantation without such therapy are a growing group of patients. Although their problems in the peri- and postmenopausal period are the same as in healthy women, due to the primary disease and treatment applied they represent a huge challenge from the point of view of their hormonal treatment of menopause. Transplanted women have no particular contraindications for hormonal therapy use. General contraindications, however, such as arterial hypertension, thrombosis in medical history, diabetes, endometriosis, myomas, or active neoplastic disease, have a higher incidence in this group of patients than in healthy women, which significantly influences the possibility of using hormonal therapy. On the other hand, taking into consideration the predisposition for premature menopause in this group, in combination with chronic immunosuppression, it predisposes these patients for higher cardiovascular disease incidence and bone density loss, so hormonal therapy would be highly advisable. Therapy management in transplanted patients requires special care and close monitoring of the transplanted organ. Saving lives with organ transplantation is one of the greatest achievements of contemporary medicine. For long-term improvement of their quality of life, emphasis should be put on regular diagnostic examinations, early detection of abnormalities, and introduction of effective treatment.

Hysterectomy and perioperative morbidity in women who have undergone renal transplantation

OBJECTIVE

The purpose of this study was to compare complications from vaginal hysterectomy with abdominal hysterectomy in renal transplant recipients.

STUDY DESIGN

Women who underwent renal transplantation then hysterectomy from 1966-2008 at Mayo Clinic, Rochester, MN, were identified. Data were collected about preoperative, intraoperative, and postoperative events. Main outcome measure was loss of allograft function; secondary outcomes included types of complications and treatment methods.

RESULTS

Of 58 women with renal transplants, 42 women (72.4%) underwent abdominal hysterectomy. The most common indication for hysterectomy was menorrhagia (n = 20; 34.5%). Overall, 24 women (41.4%) had complications, the most common of which were infection (n = 15) and transfusion (n = 8). Women who underwent abdominal hysterectomy were no more likely to have perioperative complications than were women who underwent vaginal hysterectomy (odds ratio, 1.25; 95% confidence interval, 0.38-4.08).

CONCLUSION

Although patients with renal transplants had perioperative complications, none of these complications led to renal graft loss. Hysterectomy can be considered in these patients when accompanied by diligent postoperative care.

Chemotherapy for gynecological malignancies in organ transplantation patients: report of two cases

Long-term risk of gynecological malignancies in organ transplantation patients has increased compared with that of the general population owing to the use of immunosuppressive agents. Treatment, especially chemotherapy, in these patients should take into consideration their renal function and the effects of immunosuppressive agents. We here present two case reports of patients with chemotherapy-treated gynecological malignancies who had previously received organ transplantation. The first case, a rare occurrence of simultaneous carcinomas of the uterine corpus and ovary, is the first such report in the English literature describing chemotherapy for concurrent serous papillary ovarian carcinoma and endometrioid endometrial carcinoma in a renal transplant patient. The second case report, describing chemotherapy for cervical cancer following two organ transplantation, also rare, is the first such report in the English literature and the first report of cervical cancer after heart-kidney transplantation.

Cancer after renal transplantation

PURPOSE OF REVIEW

Prolonged waiting times for renal transplantation, an increase in the average age of recipients, decreased acute rejection rates due to use of newer potent immunosuppressives and improving long-term transplant survival have raised concerns in the transplant community regarding posttransplant cancer. In view of the fact that transplant recipients are living longer, it is of paramount importance that we continue to translate discoveries at the bench to the bedside and document cancers in the posttransplant recipient registries. Analysis of data will help in optimizing patient management.

RECENT FINDINGS

Recent evidence indicates that sirolimus is associated with a decreased incidence of posttransplant de-novo cancer and remission of Kaposi's sarcoma and nonmelanoma skin cancer. Mycophenolate mofetil has been shown to have an antiproliferative activity against leukemia and lymphoma and an anti-tumor effect against colon and prostate cancer. Clinically it has been shown to be associated with a reduced incidence of cancers like posttransplant lymphoproliferative disorder.

SUMMARY

Appropriate selection of transplant candidates, pretransplant and posttransplant cancer surveillance and judicious evidence-based use of newer immunosuppressants may help reduce the incidence and improve the outcome of posttransplant cancer.
