The expression analysis of human endogenous retrovirus-K Env, Np9, and Rec transcripts in cervical cancer.

While infection with high-risk human papillomavirus (HPV) types is necessary for cervical cancer (CC) development, it is not enough, and other risk factors are required. Several studies have reported the activation of HERV-K in different cancers; however, the investigation of HERV-K expression levels in CC is scarce. In this study, it was hypothesized that activation of HERV-K could play an essential role in CC development. In this order, the expression levels of HERV-K Env, Np9, and Rec transcripts were investigated on 147 normal to CC uterine cervical tissues using quantitative real-time PCR. The significantly higher levels of HERV-K Env and Np9 transcripts were found in patients with cervical intraepithelial neoplasia (CIN) II-III and CC groups compared to those in the normal/CIN I group. Expression of Rec transcript was also higher only in the CC group than normal/CIN I group. Among CC patients, meaningfully higher levels of HERV-K Env and Np9 transcripts were found in patients with squamous cell carcinoma rather than in adenocarcinoma. When only the HPV 16 positive samples were investigated, it was found that the mean difference in Env and Np9 mRNA levels was meaningfully higher among precancer lesions and the cancer group in comparison with the normal group. However, the Rec mRNA level showed no significant differences. The association between the expression of HERV-K genes was investigated, and a significant positive correlation of Env expression with Np9 transcript was found only in the group with precancer lesions (R = 0.6, p = 0.0037). Moreover, a significant positive correlation was found between Rec and Np9 transcripts in patients with normal cervix tissues (R = 0.26, p = 0.033). However, no correlations were observed between the expression of Env and Rec in the three groups. In conclusion, our results showed that HERV-K transcripts, especially Env and Np9, upregulated during cervical lesion progression. These findings highlight the potential use of HERV-K Env and Np9 as biomarkers for CC diagnosis and prognosis. Further investigation is needed to determine the clinical utility of these markers and whether targeting HERV-K oncogenes could be a viable therapeutic strategy for CC.

Comparison of therapeutic effects of chemo-radiotherapy with neoadjuvant chemotherapy before radical surgery in patients with bulky cervical carcinoma (stage IB3 & IIA2).

BACKGROUND: Cervical cancer is one of the most common malignancies among women. Appropriate and timely treatment of these patients can reduce the complications and increase their survival. The objective of this study was to compare neoadjuvant chemotherapy plus radical hysterectomy (NACTRH) and chemo-radiotherapy (CRT) in patients with bulky cervical cancer (stage IB3 & IIA2). MATERIAL AND METHODS: The medical records of patients with bulky cervical cancer (stage IB3 & IIA2) that received NACTRH or CRT between 2007 and 2017 were evaluated for therapeutic effects. Demographic characteristics, complications of chemo-radiotherapy and neoadjuvant chemotherapy, were collected in a researcher-made questionnaire. Our primary outcome was comparison of overall survival (OS), and disease-free survival (DFS) between two groups receiving NACTRH and CRT modalities. RESULTS: One-hundred and twenty three patients were enrolled in the study. The median age and the proportion of patients with stage IIA2 were higher in the CRT group compared to the NACTRH group (p < 0.05). The medians (95% CI) OS were 3.64 (3.95-6.45) and 3.9 (3.53-4.27) years in the NACTRH and CRT groups, respectively (P = 0.003). There were 16 (34.8%) and 22 (43.1%) recurrences in the NACTRH and CRT group, respectively (P = 0.4). The median (95% CI) DFS was 4.5 (3.88-5.12) years in the NACTRH group and 3.6 (2.85-4.35) years in the CRT group (P = 0.004). The 3-year OS rate in NACTRH and CRT groups were 97 and 90% respectively. The 3-year DFS rate in NACTRH and CRT groups were 88 and 66% respectively. CONCLUSIONS: NACTRH is associated with a higher OS and DFS compared to CRT.

Serum and tissue miRNAs: potential biomarkers for the diagnosis of cervical cancer.

BACKGROUND: Finding new biomarkers for the early detection of cervical cancer is an essential requirement in this field. In this study, we aimed to evaluate the expression level of potential biomarkers in progression of cervical cancer in patients with cervical cancer compared to normal subjects. METHODS: The expression levels of tissue and serum miRNAs, including miR-9, miR-192 and miR-205, were investigated in 36 normal, 18 precancer, and 18 cervical cancer samples using real-time polymerase chain reaction. RESULTS: The results showed the higher significant expressions of miR-9, miR-192 and miR-205 in the tissue of cancer samples than those in the normal samples. Moreover, the miR-192 and miR-205 expression were significantly increased in the cancer group in comparison with the precancer group. Examination of serum samples revealed the increase in the expression level in the cancer groups than in the normal samples, for miR-9, miR-192 and miR-205 and the expressions of miR-9, miR-192 and miR-205 were significantly up-regulated in the precancer group in comparison with the normal group. Also the expression of miR-205 was remarkably increased in the cancer group in comparison with the precancer group. The receiver operating characteristic (ROC) analyses showed the highest area under the curve value for miR-192. CONCLUSIONS: Given the increased expression level of miR-192 in cancer and in precancerous tissue and serum compared with the normal tissue and serum validated by analysing the ROC curve, miR-192 can be used as potential biomarker for the early detection of cervical cancer.

Impact of diabetes mellitus on epithelial ovarian cancer survival.

BACKGROUND: Diabetes mellitus (DM) is associated with poorer outcomes in some cancers. Its effect on ovarian cancer is less clear. We consider the effect of DM on overall survival (OS) and progression free survival (PFS) in patients with epithelial ovarian cancer (EOC). METHODS: A retrospective cohort study of 215 patients with EOC diagnosed between 2009 and 2016 was performed. Records were reviewed for standard demographic, pathologic and DM diagnosis data. Cox regression was used to evaluate the relationship between disease status and survival after adjustment for age, body mass index (BMI), parity, stage, grade, histology, debulking status, hypertension (HTN), menopause status and neoadjuant chemotherapy. RESULTS: Patients with DM (27.97, 95%CI: 23.63 to 32.30) had a significantly shorter OS rates compared to patients without DM (41.01, 95%CI: 38.84 to 43.17). The unadjusted hazard ratio (HR) for the association between OS time and DM was 4.76 (95%CI: 2.99 to 7.59, P < 0.001). Following adjustment for demographic and pathologic variables, the HR was 3.93 (95% CI: 2.01 to 7.68; P < 0.001). The PFS in patients with DM (14.10, 95%CI: 11.76 to 16.44) was significantly shorter compared to patients without DM (28.83, 95%CI: 26.13 to 31.54). The unadjusted HR for PFS and DM was 5.69 (95% CI: 3.05 to 10.61; P < 0.001). After adjustment for demographic and pathologic variables, the HR was 2.73 (95% CI, 1.18 to 6.95; P < 0.001). CONCLUSIONS: DM can negatively effect on PFS and OS in EOC patients independent of the effect of other variables.

Congenital lymphangioma circumscriptum of vulva presenting as multiple giant mass lesions: a case report and literature review.

A G2L2 33-year-old woman presented to our clinic with large verrucous warty masses in labia major, perinea and the end portion of her spine measuring about 15 × 7, 9 × 7 and 8 × 8 cm, which had been enlarged following puberty and pregnancy. Her right upper and left lower limbs had gross congenital lymphedema. The masses were removed by superficial partial vulvectomy with a qualified margin and repaired without skin graft. Pathology report showed lymphangioma circumscriptum. Several months of follow up revealed normal healing and no recurrence. In conclusion, congenital vulvar lymphangioma, which is a rare disorder, can be highly triggered by hormonal-stimulating situations like puberty and pregnancy. Thus, it is better to visit the affected cases in a timely manner in order to excise these lesions before massive enlargement. In our experience, a superficial partial vulvectomy without skin graft can be a sufficient procedure. Obviously, an appropriate approach during and after surgery would be very important for obtaining a desirable healing.

Lipomatous Angiomyofibroblastoma of the Vulva: Report of a Rare Variant.

Angiomyofibroblastoma is a rare and benign tumor that usually involves vulvovaginal area in women of reproductive age and early menopause. We report a lipomatous angiomyofibroblastoma in a 55-year-old multigravid woman. This tumor measured 9 cm in size and contained prominent mature adipose tissue that comprised approximately 50% of the tumor.

Admission Test and Pregnancy Outcome.

BACKGROUND: The admission test (AT) has been carried out for many years, but there are still debates about the prognostic value of the test. Therefore, we aimed to examine the value of the AT in predicting the adverse outcome in neonates. METHODS: In this cross-sectional study, 425 pregnant women with normal vaginal delivery were studied between2009 and 2014at Vali-e-Asr Hospital. Based on the results, the women were divided into 2groups of normal and abnormal ATs. All the patients were followed up until the birth of their baby, when the status of mother and neonate was determined. The main outcomes of the study were cesarean rate, neonatal intensive care unit (NICU) admission, fetus demise, neonatal acidosis, and Apgar score. The independent t-test, chi-square test, Fisher exact test, and logistic regression were used for statistical analysis. The data were analyzed using SPSS (version 17). RESULTS: Of 425 pregnant women studied, 142 (33.4%) had abnormal ATs with a mean age of 29 (±4.5) years. Multivariate analysis showed that an abnormal AT was able to predict the incidence of cesarean section, intrauterine growth restriction, turned cord, and Apgar<7, but it could not predict neonatal death and hypoxia. CONCLUSION: The AT was shown to be a useful screening test with risk factors such as oligohydramnios, bloody amniotic fluid, meconium amniotic fluid, intrauterine growth restriction, and turned cord. Additionally, the test was also able to predict NICU admission and the need for cesarean section, but it could not predict the occurrence of neonatal death.

Evaluation of mRNA expression levels of IL-17A and IL-10 cytokines in cervical cancer.

In this study, we evaluated mRNA expression levels of interleukin (IL)-10/IL-17A by quantitative real-time PCR and their clinical importance in cervical cancer. The IL-10 mRNA levels were higher in cervical cancer tissues as compared with corresponding normal tissues (p < 0.05). Moreover, IL-17A mRNA was significantly increased in cervical cancer tissues than in normal tissues (p < 0.05). Moreover, the high expression level of IL-10 mRNA was markedly related to International League of Gynecology and Obstetrics (FIGO) stage (p = 0.001), but no significant association was found with other clinical factors including age, tumor size, histological grades, and lymph node metastasis. Moreover, high expression levels of IL-17A were not associated with patients' age, tumor size, FIGO stage, and histological grades while IL-17A expression was strongly linked to lymphatic metastasis (p = 0.001). These findings showed that IL-17A might have a crucial role in cervical cancer metastasis. Taken together, IL-17A expression was strongly linked to lymphatic metastasis, indicating that IL-17A might have a crucial role in cervical cancer metastasis. Moreover, our study suggested the association of IL-10 mRNA expression with clinical stage.

Mediators of repeat mammography in two tailored interventions for Iranian women.

BACKGROUND: Many theory-based interventions exist that incorporate theoretical constructs (e.g., self-efficacy, behavioral control) believed to increase the likelihood of mammography. Nonetheless, little work to date has examined if increased screening among women receiving such interventions occurs due to changes in these targeted constructs. The aim of this study is to address this gap in the literature in the context of two interventions for improving regular screening among Iranian women. METHODS: A sample of 176 women over 50 years old in Tehran, Iran were randomly allocated into one of these three conditions: 1) an intervention based on Health Belief Model (HBM); 2) an intervention based on an integration of the HBM and selected constructs from the TPB (TPB); and 3) a control group (CON). Questionnaires were administered before the intervention and after a 6-month follow-up. The Preacher and Hayes method of mediation was used in analytic models. RESULTS: Changes in susceptibility, self-efficacy, and perceived control appeared to mediate HBM-CON differences in screening. Barriers attenuated the mediating effect of self-efficacy. Changes in barriers and self-efficacy appeared to mediate TPB-CON differences in screening. CONCLUSION: This study was successful in identifying which theory-based constructs appear to underlie the effectiveness of HBM- and TPB-based interventions. Specific constructs have been identified that should be targeted in clinical practice to increase mammography practices among Iranian women.

Congenital microtia in a neonate due to maternal isotretinoin exposure 1 month before pregnancy: Case Report.

Isotretinoin is a drug used for treating severe cystic/nodular acne. Severe malformations have been documented in neonates whose mothers had taken isotretinoin during pregnancy. Women who became pregnant one cycle after completing therapy are believed to be at teratogenic risk not higher than baseline. We describe the case of a newborn whose mother had taken the drug for 4 weeks. The woman then had contraception for 4 weeks (after the drug treatment had finished), and became pregnant after that period. The newborn had isolated bilateral microtia due to suspected isotretinoin exposure. His mother also had a history of urine tract infection in the second week of pregnancy that was treated with cephalexin. The parents were not from a consanguineous marriage and had no family history of congenital malformations. To reduce the risk, effective contraception should be continued in fertile women more than 1 month after completing therapy.

Efficacy of combination therapy of oral zinc sulfate with imiquimod, podophyllin or cryotherapy in the treatment of vulvar warts.

AIM: Zinc sulfate is beneficial in the treatment of epithelial warts. We conducted this study to compare the efficacy of combination therapy of oral zinc sulfate with conventional treatments in the treatment of vulvar warts. MATERIAL AND METHODS: This study was a randomized controlled trial. The sample size was 42 in each group. Women aged 20-50 years were placed by the block randomized method into six groups: the podophyllin-, imiquimod- and cryotherapy-treated groups, and another three groups receiving 8-week combination therapy of 400 mg oral zinc sulfate with one of the above-mentioned treatments. Data were analyzed using anova and Fischer's exact test with spss16. RESULTS: A total of 228 patients were recruited and completed the study in six treatment groups. No significant difference was observed in the response to treatment among these groups. Relapse after 6 months was significantly higher in the podophyllin-, imiquimod- and cryotherapy-treated patients compared to patients receiving these treatments in combination with oral zinc sulfate (P<0.05). CONCLUSIONS: Combined therapy of oral zinc sulfate with conventional treatments of vulvar warts appears to reduce the relapse rate.

Type-specific human papillomavirus prevalence in women referred for colposcopy in Tehran.

Background and Objectives: Although several studies have been achieved on the frequency of the HPV types among women with cervical cancer in Iran, HPV-positive samples were in some cases directed to specific-primer genotyping of HPV 16 and 18. Therefore, the other HPV types are underestimated. Several studies have also reported a greater prevalence of HPV 16 in cervical cancer in Iran than in the world. To clarify these subjects, the distribution of HPV types in women referred for colposcopy in Tehran was investigated. Materials and Methods: In this cross-sectional study, a total of 148 cervical samples from women with normal, atypical squamous cells of undetermined significance, cervical intraepithelial neoplasia I-III, and invasive cervical cancer histopathology were included. HPV was detected by PCR assay and all HPV-positive specimens were subjected to direct nucleotide sequencing. Results: Our results demonstrated that the total prevalence of HPV was 92.5%. The five most common HPV types were HPV 16 (49.3%), 18 (14.8%), 6 (7.4%), 31 (4.1%), and 11 (2.7%). About the histopathological stage, HPV 16 and 18 were dominant in all studied groups. In cervical cancer, HPV 16 and 18 were detected in 60% and 20% of cases, respectively. Conclusion: HPV 16 and 18 were the most common in cervical cancer in Iran.

Pattern Recognition or Adnexal MR Scoring System: Which Is More Accurate in Evaluating Adnexal Lesions?

PURPOSE: This study aims to compare the accuracy of the ADNEX MR scoring system and pattern recognition system to evaluate adnexal lesions indeterminate on the US exam. METHODS: In this cross-sectional retrospective study, pelvic DCE-MRI of 245 patients with 340 adnexal masses was studied based on the ADNEX MR scoring system and pattern recognition system. RESULTS: ADNEX MR scoring system with a sensitivity of 96.6% and specificity of 91% has an accuracy of 92.9%. The pattern recognition system's sensitivity, specificity, and accuracy are 95.8%, 93.3%, and 94.7%, respectively. PPV and NPV for the ADNEX MR scoring system were 85.1 and 98.1, respectively. PPV and NPV for the pattern recognition system were 89.7% and 97.7%, respectively. The area under the ROC curve for the ADNEX MR scoring system and pattern recognition system is 0.938 (95% CI, 0.909-0.967) and 0.950 (95% CI, 0.922-0.977). Pairwise comparison of these AUCs showed no significant difference (p = 0.052). CONCLUSION: The pattern recognition system is less sensitive than the ADNEX MR scoring system, yet more specific.

Hypofractionated versus standard chemoradiotherapy in the definitive treatment of uterine cervix cancer: interim results of a randomized controlled clinical trial.

PURPOSE: Concurrent chemoradiation has been the mainstay of treatment for cervix cancer. We aimed to evaluate the non-inferiority of hypofractionated chemoradiation. METHODS: This study was designed as a phase 2, 1:1 randomized, investigator-blinded, controlled, non-inferiority trial and we report the interim results after 50% accrual. Cervical cancer patients with FIGO stages IIA-IIIC were recruited from April 2021 to September 2022. The intervention consisted of 40 Gy of 3D-conformal radiation therapy (RT) in 15 fractions over 3 weeks. In the control group, patients received standard chemoradiation of 45 Gy in 25 fractions over 5 weeks. Both groups received concurrent weekly cisplatin (40 mg/m2). Intravaginal brachytherapy of 28 Gy in 4 weekly fractions was delivered starting 1 week after the end of chemoradiation. The primary outcome was complete clinical response(CCR) at 3 months. Secondary outcomes included acute gastrointestinal (GI), genitourinary(GU), skin, and hematologic toxicities. A p value less than 0.05 was considered significant for analyses. RESULTS: 59 patients were randomized; 30 in the control group and 29 in the intervention group. 20/30 (66.7%) of the patients in the control group and 19/29 (65.5%) in the intervention group achieved a CCR (absolute difference of 0.011, 95% CI - 0.23 to 0.25, p value: 0.13). There was a significantly higher rate of acute grade ≥ 3 GI toxicity in the intervention group (27.6%) compared with the control group (6.7%) (p value 0.032). CONCLUSIONS: Despite an absolute difference of 1.1% in the 3-month CCR, our interim analysis failed to show the non-inferiority of the hypofractionated chemoradiation. Due to the higher GI toxicities, we will continue this trial using intensity-modulated radiation therapy. REGISTRATION NUMBER AND DATE: ClinicalTrials.gov: NCT04831437, 2021.4.1.

Rare presentation of retroperitoneal leiomyosarcoma mimicking a myoma in a 46-year-old woman: A case report.

Retroperitoneal sarcoma is relatively uncommon. We share our experience in encountering retroperitoneal sarcoma with vascular and urethral adhesion in a 46-year-old woman. Given the rarity of these tumors, evaluation and management should ideally be performed in a center equipped with multidisciplinary expertise in treating sarcomas.

Resistance to single-agent chemotherapy in low-risk gestational trophoblastic neoplasia.

Background: Methotrexate (MTX) and actinomycin D (ActD) have been used as first-line chemotherapy agents in the treatment of low-risk gestational trophoblastic neoplasia (GTN). Although low-risk GTN is considered a curable disease, its reported primary remission rates of 49 to 93% reflect the difficulties of treatment and different factors influencing it. Hence, this study aimed to determine the remission rates and related factors of single-agent chemotherapy resistance in low-risk GTN patients. Methods: This retrospective study included patients with diagnosed low-risk GTN who received either MTX once a week (IM, 30mg/m2) or ActD once every two weeks (pulsed IV, 1.25mg/m2). Then, the patients were followed-up until complete remission or single-agent treatment failure to assess resistance rate and related factors. Results: Eighty-four patients were included in the study (18 patients were receiving MTX and 66 patients were receiving ActD). 85.7% of all participants achieved complete remission after first-line chemotherapy (72.2% in MTX vs 89.4% in ActD). There was a significant association for higher tumor size (P=0.046), the occurrence of metastasis (P=0.019), and pretreatment ß-HCG levels (P=0.005) with resistance to treatment. Conclusion: This study demonstrated higher tumor size, the occurrence of metastasis, and pretreatment ß-HCG levels have been associated with increased resistance to first-line chemotherapy agents.

Pathologic examination of the placenta and its benefits in treatment plan or follow-up of patients: a cross-sectional study.

BACKGROUND: The placental examination provides important information about the effect of maternal abnormalities on the placenta or the cause of preterm delivery, fetal growth restriction, or fetal neurodevelopmental damage. In this study, the frequency of placental pathologies of patients in a tertiary hospital was investigated. METHODS: In this longitudinal and cross-sectional study, all removed placentas after any type of pregnancy termination referred to a pathological examination, within 1 year (2019-2020). All placentas were examined macroscopically and microscopically by two pathologists. RESULTS: Unfortunately, because of the COVID-19 pandemic, the number of pregnant women in our hospital declined. A total of 258 placentas were examined. The type of delivery in 193 cases (79.4%) was cesarean section and 50 cases (20.6%) had a vaginal delivery. In the pathological assessment of placentas, 238 (92.2%) cases were normal and 20 cases (7.8%) were abnormal. Infarct and chorioamnionitis were the pathologies with higher frequencies (4.3% and 2.7%, respectively). Intra-uterine fetal death (p = 0.701), preeclampsia (p = 0.51) had no significant difference was seen in normal and abnormal placentas. Maternal age (p = 0.83), gestational age based on the last menstrual period (p = 0.38), and gestational age based on the first ultrasound (p = 0.78) did not show a significant relationship with any of the pathological complications categories. CONCLUSIONS: Pathological examination of the placenta from all live-birth deliveries is not worthwhile, and it's recommended to modify the guidelines as to when the placenta is submitted for pathological evaluation.

Ovarian small cell carcinoma by ovarian torsion feature: A cytopathology challenging case.

INTRODUCTION AND IMPORTANCE: Ovarian small cell carcinomas are a rare type of ovarian cancer that is highly aggressive and consists of two distinct types the hypercalcemic type (SCCOHT) and pulmonary type (SCCOPT). CASE PRESENTATION: A 23 years old girl was admitted to the emergency room with the presentation of acute abdomen. The ultrasound and Magnetic resonance imaging revealed a right adnexal huge mass with adnexal torsion. In laparotomy, she underwent unilateral salpingo-oophorectomy due to ovarian torsion and possible malignancy. The histopathological evaluation was challenging and was finalized by a team of pathologists as hypercalcemic small cell carcinoma. She refused reoperation and unfortunately relapsed during chemotherapy and died 6 months after the initial diagnosis. CLINICAL DISCUSSION: Conclusion: We do not yet have comprehensive information on small cell ovarian cancer. Cytopathology diagnosis is still challenging and the treatments are not usually effective. Further clinical trials and studies are recommended to find appropriate treatments for these patients.

A Virtual Instructional Design Improved Breaking Bad News in Obstetrics and Gynecology Residents.

Objective: Breaking bad news to the patient is challenging, especially for the physicians and the residents, due to the lack of structured and practical training. This study aimed to design and evaluate a novel virtual instructional design for improving obstetrics and gynecology (Ob/Gyn) residents breaking bad news skills. Materials and methods: Virtual instructional design was performed based on the ADDIE model (Analysis, Design, Development, Implementation and Evaluation) from September 2020 to July 2021 at the Department of Ob/Gyn, a referral hospital affiliated with Tehran University of Medical Sciences, Tehran. Iran. The five steps of ADDIE virtual instructional design were applied sequentially. Results: Totally 33 of the Ob/Gyn residents included in the study that 77% needed specific training. The awareness of the performance of the residents in seven areas including interview context, strategy, planning, professionalism, empathy, knowledge, and receiving information needed to be trained for breaking bad news. The content of the virtual training package was designed based on the prior assessment needs in four multimedia lectures of professors, one short educational video, a 65-page file that combines text and images in 4 parts. The pre-test and post-test mean scores (SD) were 9.45 (2.0) and 10.67 (1.7), respectively (p-value≤0.001) in the cognitive and attitudinal domain. In the final step, the final corrections were made in the virtual training package. Interestingly, the satisfaction of residents' attitudes was 96.5%. Conclusion: Most Ob/Gyn residents do not have the necessary perception and skills to deliver bad news to the patients. Designing an appropriate virtual training package for improving communication skills is associated with satisfaction. Thus, the efficacy of the training program should be implemented for all Ob/Gyn residents.

A Systematic Review on Overall Survival and Disease-Free Survival Following Total Pelvic Exenteration.

BACKGROUNDS: Total Pelvic Exenteration (TPE) is a radical operation for malignancies in which all of the organs inside the pelvic cavity, including the female reproductive organs, the lower urinary tract, and a part of the rectosigmoid are removed. In this study, we aimed to conduct a systematic review to assess the overall survival (OS) and disease-free survival (DFS) following TPE. METHODS: This systematic review is composed of a comprehensive review of PubMed and Scopus databases with various related keywords to synthesis the overall survival and disease-free survival following TPE. The Synthesis Without Meta-analysis guideline was used to summarize the results. RESULTS: We included the results of 39 primary studies and the results revealed that one-year OS of gynecological cancer in patients who have undergone TPE ranged from 50.0% to 72.0% and the 5-years OS ranged from 6.0% to 64.6%. The one-year survival rate of colorectal cancer patients was reported to be over 80% in almost all studies. The 3-year survival rate of patients varied from 25% to 75% and the lowest 5-year survival rate was 8% and the highest survival rate was 92%. To synthesis the disease-free survival rate in colorectal cancer, ten studies were included and one-year recurrence rate was 9.1% and the one-year DFS was reported as 61.0%. Three-year recurrence rate study was 20.4% and 3 and 5-year DFS ranged from 22.0% to 78.0%. CONCLUSIONS: The results suggested that DFS in primary advanced cancers is higher than locally recurrence tumors. This review showed that patient overall survival and disease-free survival rates have increased over time, especially at high volume centers that are more experienced and possibly better equipped. Therefore, it can be suggested that the attitude towards PE as a palliative surgery can be turned into curative surgery.
