Specific Molecular Signatures Predict Neoadjuvant Chemotherapy Response in Cervical Cancer

Uterine Cervical NeoplasmsCervical Cancer1 more

Cervical cancer is one of the major health problems for chinese women. Besides surgery and radiotherapy, neoadjuvant chemotherapy has been proved to be an effective program by many studies. However, not all patients respond well to neoadjuvant chemotherapy. Knowing the therapeutic effect of the neoadjuvant chemotherapy before receiving it can not only reduce the economic burden, but also more importantly save time to take more suitable treatments. This study is undertaken to build specific molecular signatures to predict the effects of neoadjuvant chemotherapy.

Triage Strategies in Cervical Cancer Prevention

Cervical CancerIntraepithelial Neoplasia

While there is broad consensus that HR-HPV detection is the best available primary screening test, there is no agreement about the most efficient and reliable triage procedure for HR-HPV positive women. Transient HR-HPV infections are very common, and the vast majority of these infections spontaneously regress after a year or two. Only a small fraction of cases will lead to persistent infection responsible for cervical neoplasia. The FRIDA Study is a large, population-based study that was designed to evaluate the performance and cost-effectiveness of different triage strategies for hrHPV-positive women in Mexico.

An International Study on Magnetic Resonance Imaging (MRI)-Guided Brachytherapy in Locally Advanced...

Cervical Cancer

Background: The standard treatment of locally advanced cervical cancer is radio-chemotherapy including external beam radiotherapy (EBRT), brachytherapy (BT) and concomitant chemotherapy with weekly Cisplatin. While image based conformal EBRT is routinely used, prescription and reporting of BT is still based on specific dose points defined in 2D. Thus, for several decades the BT dose has most often been prescribed and reported to the Manchester point A defined according to different traditions. Recently, a working group from GEC-ESTRO has published recommendations on contouring of tumour target and organs at risk (OAR) as well as on dose volume parameters to be reported for image guided BT in definitive radiotherapy for locally advanced cervical cancer. These recommendations are mainly derived from retrospective single institution experience with MRI based intracavitary BT. The major advantage of this technique is the possibility to conform the dose given by BT with regard to both volume (3D) and time (4D). Thus, by repetitive imaging performed before each BT implant it is possible adapt the dose given by BT to the anatomy of each individual patient taking into account not only the position of OAR but also the tumour regression which often is obtained by preceding EBRT and chemotherapy. Based on the experience collected so far, the image based BT approach is expected to have a major impact on the clinical outcome with a concomitant decrease in the rates of both local failure and morbidity. Aims: To introduce MRI based 3D-4D BT in locally advanced cervical cancer in a multicenter setting within the frame of a prospective observational study. To establish a bench-mark for clinical outcome with image based BT in a large patient population with respect to local control, survival, morbidity and QoL To establish a reference material with regard to image based DVH parameters according to the guidelines from the GEC ESTRO working group. To correlate image based DVH parameters for CTV and for OAR with outcome To develop prognostic and predictive statistical models for clinical outcome including volumetric, dosimetric, clinical and biological risk factors To establish radiobiological parameter estimates that will allow a precise risk estimation in individual patients and aid in the development of new treatment protocols

Observation and Evaluation of Short-term Curative Effect of Local Advanced Cervical Cancer Treated...

Uterine Cervical NeoplasmsLocally Advanced Cervical Cancer

Locally advanced cervical cancer (LACC) refers to the clinically cervical visible lesion with a diameter of > 4 cm, which has been considered as a high risk of early cervical cancer for a long time. Because of local bulk lesion of LACC, the risk of radical hysterectomy is pretty high and the radical effect commonly does not meet the satisfactory. Therefore, 1-3 course of neoadjuvant chemotherapy (NACT) were carried out before operation. However, nearly 20% of patients are not sensitive to NACT. Therefore NACT did not bring any benefits to radical surgery even to some extent delayed the treatment. Traditional radiotherapy is also commonly used in the treatment of LACC, however ovarian function would be permanently destroyed especially for young patients, additionally radioactive complications to adjacent organs of cervical such as vagina, bladder and rectal also commonly happened, moreover sexual dysfunction after radiotherapy significantly affect the life quality of young patients. Particle radiotherapy developed recently, has the advantages of short course of treatment and mild side effects, due to its special working mechanism, Bragg effect. So the amount of radiation in the tumor tissue is very extremely high, and in the adjacent tissue is quiet low, therefore the organs at risk were protected by avoiding unnecessary damage. Based on these, we proposed the application of particle radiotherapy in LACC pre-operation, and comprehensively evaluated recent curative effect, complications and long-term follow-up between particle radiotherapy and NACT. Furthermore, the clinical significance and long-term application prospects about particle therapy were objectively assessed.

Evaluation of Vaginal Dose in Cervical Cancer Patients Treated With Radiotherapy

Cervical Cancer

Cervical cancer is the most common malignant in women with the average five-year overall survival rate as high as 70%. Radiation therapy is the main treatment for cervical cancer. Vagina is one of the important organ at risk and also a target organ in the treatment of cervical cancer patients. Vaginal radiation has serious related complications that affect the quality of life of patients and therefore needs much clinical attention. But due to lack of sufficient evidence, the clinical dose to the vagina is limited. ICRU-89 defined the recto-vaginal reference point (R-V) as a reference point for vaginal dose assessment. However, the R-V position is affected by applicator placement, vaginal packing and other factors hence the dose point only do not represent the entire vaginal radiation dose resulting in some clinical limitations. The latest research in Europe proposed that PIBS(Posterior-Inferior Border of Symphysis) / PIBS ± 2cm and VRL (vaginal reference length) may be more reasonable to use to assess vagina radiation doses, but it remains to be further clinically investigated. Therefore, this study intends to perform radical radiotherapy in cervical cancer patients and also by recruiting local and foreign hospitals into this study by recording its PIBS/ PIBS ± 2cm, VRL, R-V point dose, acute and chronic radiation injury incidence of vagina and other useful data. T-test and chi-square will be used to compare the data between Asian and European women. Correlation analysis will be used to determine if there is a relation between R-V and PIBS point dose. Furthermore, logic and or COX regression model to evaluate PIBS / PIBS ± 2cm and R-V point doses of vaginal radiation injury relationships, while exploring other relevant factors causing vaginal radiation injury. This is eventually expected to provide a scientific, simple and reliable reference point for vaginal dose assessment and clinical dose limit.

Precancerous LesionsConization5 more

This study is to investigate the oncologic and obstetric outcomes in patients with conization for uterine cervical lesions from January 1, 2000 to January 1, 2019 in Peking Union Medical College Hospital. The primary objectives consist of following: The cumulative incidences of precancerous lesions and cancers of lower genital tract in patients who accepted conization for high grade intraepithelial neoplasia (HSIL), carcinoma in situ and stage IA1 cancer (FIGO 2009) The cumulative pregnancy rates in patients sparing the fertility The secondary objectives consist of following: The effects of surgical protocols (modified Sturmdorf method and "8" figure suture) and energy equipment (cold knife and monopolar electrical cautery) on the oncologic and obstetric outcomes, and on the histological components. A full description of histological components of the conization specimens The cytological and virus outcomes after conization, based on the thin prep liquid-based cytology test (TCT) and high-risk human papillomavirus (HPV) testing
