Carp-Velişcu, Prof. Young survivors who have not completed their family yet have now a chance given by oncofertility procedures. The main strategies used in preserving fertility in oncology uterine cancer nccn guidelines are: ovarian stimulation followed by cryopreservation of oocytes, transposition of the ovaries before radiotherapy, cryopreservation and transplantation of ovarian tissue, and the administration of gonadotropin-releasing hormone GnRH agonists, each technique being individualized for each patient.

Keywords oncofertility, cryopreservation, survival, fertilization Rezumat Oncofertilitatea este o nouă ramură a medicinei, dezvoltată din nevoia de a trata cel mai frecvent efect secundar pe termen lung al tratamentului oncologic — infertilitatea. Tinerele supravieţuitoare care încă nu şi-au completat familia au acum o şansă prin procedurile de oncofertilitate.
Oncofertilitatea – o şansă la o viaţă normală pentru tinerele supravieţuitoare ale cancerului
Principalele tehnici folosite în conservarea fertilităţii pacientelor oncologice sunt: stimularea ovariană urmată de crioprezervarea ovocitelor, transpoziţia ovarelor înainte de iniţierea radioterapiei, crioprezervarea şi transplantarea ulterioară a ţesutului ovarian, administrarea de agonişti GnRH. Alegerea uterine cancer nccn guidelines se face individualizat, pentru fiecare pacientă în parte. Nowadays, because of new screening methods, remarkable treatments and early diagnosis, the survival has increased for oncology patients, but with hpv virus cervical smear very high cost — infertility.
Materials and method We performed a systematic review of published uterine cancer nccn guidelines describing the effects of cancer treatment on fertility and the current strategies used for preserving fertility in oncology patients, using the PubMed and Medline databases.
For instance, hair loss, which is one of the major concerns for some patients, such as a young lady with BM of breast cancer, is a less frequently encountered problem with SRS than WBRT as a result of the smaller irradiated field size and focalized dose distribution Figure 2. All the aforementioned advantages of SRS are provided by utilization of multiple convergent narrow beams to deliver high dose focal irradiation in a single fraction by using multiple cobalt sources, linear accelerators or cyclotrons 37, Similar with neurosurgery, SRS alone or in combination with WBRT has been exhibited to associate with prolonged overall survival, local control and also better neurologic status in these patients compared to WBRT alone 33,
Risk of uterine cancer nccn guidelines related to chemotherapeutic agent Aggressive chemotherapy, especially when using an alkylating agent which has a higher gonadotoxic potential and radiotherapy, cause premature ovarian failure due to destruction of the ovarian reserve, resulting in infertility, years of hormone replacement therapy and menopause-related symptoms. Each chemotherapeutic agent has a different mechanism of action and, consequently, a distinct impact on ovary reserve Table 1.
Table 1. Risk of infertility related to chemotherapeuric agents New pharmacological agents with the purpose to protect the ovary during chemotherapy are developing, most of them being still in preliminary stages of study 3. Women who require gonadotoxic treatment should receive an individual evaluation for fertility preservation.
Even nowadays, fertility preservation uterine cancer nccn guidelines are not routinely presented to patients before starting the oncological treatment, and these methods are still underused. uterine cancer nccn guidelines
Oncofertility – a chance to a normal life for cancer young survivors
The current techniques used in preserving fertility in women diagnosed with cancer are: ovarian stimulation followed by cryopreservation of unfertilized oocytes or fertilized oocytes, transposition of the ovaries before radiotherapy, cryopreservation and transplantation of ovarian tissue, uterine cancer nccn guidelines the administration of gonadotropin-releasing hormone GnRH agonists during the oncological treatment.
Ovarian stimulation, followed by intracytoplasmic sperm injection ICSI and cryopreservation of embryos, is currently the first recommendation for fertility preservation in newly diagnosed cancer patients.
Oocyte banking uterine cancer nccn guidelines not require a partner or a sperm donor at the moment of cryopreservation. Cryopreservation of ovarian tissue before starting the oncological treatment has recently become one of the most promising techniques for preserving fertility, especially when there is no time for ovarian uterine cancer nccn guidelines. It allows the storage of a large number of primordial and primary follicles.
It is the single actual option for preserving fertility in prepubertal oncological patients who do not produce already mature oocytes for freezing 5. A major worry using this method is the potential risk of grafting malignant cells. The method evaluates the tissue using immunohistochemistry tests and molecular biology techniques, thus the reimplantation of ovarian tissue appeared to be safe, including in patients diagnosed with breast cancer, lymphoma cancers and sarcoma.
In leukemia patients, the disease must be in full remission 7.

Also, in patients with BRCA mutations, the ovarian tissue cryopreservation is not an option because it increases the risk of ovarian cancer. For this group of patients, bilateral salpingo-oophorectomy is done for preference after childbearing, so that these patients are candidates for either embryo crypreservation or oocyte cryopreservation 8.
Regarding ovarian transposition, ovaries can be moved from the area receiving radiation; the method is not efficient against chemotherapy effect 9. Ovarian supression using GnRH agonist during chemotherapy should be considered an option for ovarian preservation in premenopausal patients who are not interested any more in conceiving, but who consider ovarian insufficiency a negative impact on their quality of life.
There are no current data available in literature to prove the negative interaction between ovarian supression therapy and chemotherapy.
Fertility preservation in gynecologic malignancies Fertility preservation techniques are used in gynecologic malignancies such as cervical cancer, where the focus in preserving fertility consist in conservative surgery uterine cancer nccn guidelines surgery is a surgical treatment in which one ovary and the uterus are conserved.
In ovarian malignant pathology, conservative gonadal surgery can be done in the following pathologies: any stage of malignant germ cell tumors, sex cord stromal tumors, stage I invasive epithelial ovarian cancer, and borderline ovarian tumors.
Borderline ovarian tumors appear usually in young women, this is why fertility conservation is an important consideration, and they usually have uterine cancer nccn guidelines excellent survival rate.
Letrozole during ovarian stimulation should be considered in order to reduce the risk of increasing recurrences.
Ovarian cortex cryopreservation is not justified given the possible risks of malignant reseeding; this approach would appear to be contraindicated at least for the moment.
In stage IA of ovarian epithelial cancer, unilateral anexectomy may be done in selected patients who wish uterine cancer nccn guidelines procreate 8. In endometrial cancer, the standard therapeutic manner is hysterectomy with bilateral anexectomy; a fertility sparing method is the continuous administration of progestin medroxiprogesteron therapy in very rigorous selection of patients with endometrial hyperplasia or stage IA endometrial adenocarcinoma Breast malignancy is the leading cause of cancer in women of reproductive age.
For many of them, after surgery and chemotherapy it follows five years of con-tinuous treatment with tamoxifen, when they will not be able to attempt pregnancy.

Even if tamoxifen is not necessary, current recommendation is to delay pregnancy for at least two years after diagnosis, due to the higher rate of recurrence during this period Because a high estrogen status is not considered safe for these patients, oocyte uterine cancer nccn guidelines can be performed during natural cycles, but usually no more than a single embryo can be obtained.
Uterine cancer nccn guidelines, because pregnancy rates increase in parallel with the number of embryo transfers, in vitro fertilization stimulation cycles can be done with tamoxifen or letrozole, increasing considerably the number of pregnancies.
Conclusions The preservation of fertility has become one of the major gain in quality of life for oncology patients undergoing chemotherapy or radiotherapy at reproductive ages and proactively addressing is associated with lower regret and improved quality of life, thus counseling regarding the expected success rates may be difficult in such patients Conflict of interests: The authors declare no conflict of interests.
