Cervical cancer continues to be among the most common malignancies in women, and in recent decades, important measures have been taken to reduce its incidence. The first and most important steps to achieve this goal are oriented toward prevention through screening programs and vaccination, mainly against oncogenic human papillomavirus (HPV) strains 16 and 18. The therapeutic approach is based on the diagnosis and treatment guidelines for cervical cancer, which establish for each stage (FIGO, TNM) specific conduct. These guidelines summarize quite precisely the elements of therapeutic practice, but, in some places, they leave optional variants based on which nuanced approaches could be established. Adherence to these guidelines, which include the performing of minor or major surgery, with or without chemotherapy and radiation therapy, combined with advanced imaging investigations, has been able to lead to a substantial increase in survival. The purpose of this literature review is to discuss the diagnosis and treatment options in cervical cancer depending on the histological type, FIGO staging, and patient performance index, taking into account the hospital resources available in middle-income countries (percentage of gross domestic product allocated to health services around 5.5%, in the case of Romania).

There is still no curative treatment for the spontaneous preterm prelabor rupture of membranes (sPPROM), the main cause of premature birth. Here, we summarize the most recent methods and materials used for sealing membranes after sPPROM. A literature search was conducted between 2013 and 2023 on reported newborns after membranes were sealed or on animal or tissue culture models. Fourteen studies describing the outcomes after using an amniopatch, an immunologic sealant, or a mechanical cervical adapter were included. According to these studies, an increase in the volume of amniotic fluid and the lack of chorioamnionitis demonstrate a favorable neonatal outcome, with a lower incidence of respiratory distress syndrome and early neonatal sepsis, even if sealing is not complete and stable. In vivo and in vitro models demonstrated that amniotic stem cells, in combination with amniocytes, can spontaneously repair small defects; because of the heterogenicity of the data, it is too early to draw a thoughtful conclusion. Future therapies should focus on materials and methods for sealing fetal membranes that are biocompatible, absorbable, available, easy to apply, and easily adherent to the fetal membrane.

Introduction: Cervical cancer is among the most frequent types of neoplasia worldwide and remains the fourth leading cause of cancer death in women, a fact that raises the necessity for further development of therapeutic strategies. NCCN guidelines recommend radiation therapy with or without chemotherapy as the gold standard for locally advanced cervical cancer. Also, some studies claim that performing surgery after chemo-radiation therapy does not necessarily improve the therapeutic outcome. This study aims to determine the impact of the risk factors, various characteristics, and surgical treatment for patients in different stages of the disease on survival rate. Material and methods: Our study started as a retrospective, observational, unicentric one, carried out on a cohort of 96 patients diagnosed with cervical cancer from the surgical department of the Bucharest Oncological Institute, followed from 1 January 2019 for a period of 3 years. After the registration of the initial parameters, however, the study became prospective, as the patients were closely monitored through periodical check-ups. The end-point of the study is either the death of the participants or reaching the end of the follow-up period, and, therefore, we divided the cohort into two subgroups: the ones who survived after three years and the ones who did not. All 96 patients, with disease stages ranging from IA2 to IIIB, underwent radio-chemotherapy followed by adjuvant surgery. Results: Among the 96 patients, 45 (46%) presented residual tumor after radio-chemotherapy. Five patients (5%) presented positive resection margins at the post-operative histopathological examination. The presence of residual tumor, the FIGO stage post-radiotherapy, positive resection margins, and lympho-vascular and stromal invasions differed significantly between the subgroups, being more represented in the subgroup that reached the end-point. Variables correlated with the worst survival in Kaplan–Meier were the pelvic lymph node involvement—50% at three years (p—0.015)—and the positive resection margins—only 20% at three years (p < 0.001). The univariate Cox model identified as mortality-associated risk factors the same parameters as above, but also the intraoperative stage III FIGO (p < 0.001; HR 9.412; CI: 2.713 to 32.648) and the presence of post-radiotherapy adenopathy (p—0.031; HR: 3.915; CI: 1.136 to 13.487) identified through imagistic methods. The independent predictors of the overall survival rate identified were the positive resection margins (p—0.002; HR: 6.646; CI 2.0 to 22.084) and the post-radiotherapy stage III FIGO (p—0.003; HR: 13.886; CI: 2.456 to 78.506). Conclusions: The most important predictor factors of survival rate are the positive resection margins and the FIGO stage after radiotherapy. According to the NCCN guidelines in stages considered advanced (beyond stages IB3, IIA2), the standard treatment is neoadjuvant chemoradiotherapy. In our study, with radical surgery after neoadjuvant therapy, 46% of patients presented residual tumor at the intraoperative histopathological examination, a fact that makes the surgical intervention an important step in completing the treatment of these patients. In addition, based on the patient’s features/comorbidities and the clinical response to chemotherapy/radiotherapy, surgeons could carefully tailor the extent of radical surgery, thus resulting in a personalized surgical approach for each patient. However, a potential limitation can be represented by the relatively small number of patients (96) and the unicentric nature of our study.

Background and Objectives: Cervical cancer is the fourth most frequent type of neoplasia in women. It is most commonly caused by the persistent infection with high-risk strands of human papillomavirus (hrHPV). Its incidence increases rapidly from age 25 when routine HPV screening starts and then decreases at the age of 45. This reflects both the diagnosis of prevalent cases at first-time screening and the likely peak of HPV exposure in early adulthood. For early stages, the treatment offers the possibility of fertility preservation.. However, in more advanced stages, the treatment is restricted to concomitant chemo-radiotherapy, combined, in very selected cases with surgical intervention. After the neoadjuvant treatment, an imagistic re-evaluation of the patients is carried out to analyze if the stage of the disease remained the same or suffered a downstaging. Lymph node downstaging following neoadjuvant treatment is regarded as an indubitable prognostic factor for predicting disease recurrence and survival in patients with advanced cervical cancer. This study aims to ascertain the important survival role of radiotherapy in the downstaging of the disease and of lymphadenectomy in the control of lymph node invasion for patients with advanced-stage cervical cancer. Material and Methods: We describe the outcome of patients with cervical cancer in stage IIIC1 FIGO treated at Bucharest Oncological Institute. All patients received radiotherapy and two-thirds received concomitant chemotherapy. A surgical intervention consisting of type C radical hysterectomy with radical pelvic lymphadenectomy was performed six to eight weeks after the end of the neoadjuvant treatment. Results: The McNemar test demonstrated the regression of lymphadenopathies after neoadjuvant treatment—p: <0.001. However, the persistence of adenopathies was not related to the dose of irradiation (p: 0.61), the number of sessions of radiotherapy (p: 0.80), or the chemotherapy (p: 0.44). Also, there were no significant differences between the adenopathies reported by imagistic methods and those identified during surgical intervention—p: 0.62. The overall survival evaluated using Kaplan-Meier curves is dependent on the post-radiotherapy FIGO stage—p: 0.002 and on the lymph node status evaluated during surgical intervention—p: 0.04. The risk factors associated with an increased risk of death were represented by a low preoperative hemoglobin level (p: 0.003) and by the advanced FIGO stage determined during surgical intervention (p-value: 0.006 for stage IIIA and 0.01 for stage IIIC1). In the multivariate Cox model, the independent predictor of survival was the preoperative hemoglobin level (p: 0.004, HR 0.535, CI: 0.347 to 0.823). Out of a total of 33 patients with neoadjuvant treatment, 22 survived until the end of the study, all 33 responded to the treatment in varying degrees, but in 3 of them, tumor cells were found in the lymph nodes during the intraoperative histopathological examination. Conclusions: For advanced cervical cancer patients, radical surgery after neoadjuvant treatment may be associated with a better survival rate. Further research is needed to identify all the causes that lead to the persistence of adenopathies in certain patients, to decrease the FIGO stage after surgical intervention, and, therefore, to lower the risk of death. Also, it is mandatory to correctly evaluate and treat the anemia, as it seems to be an independent predictor factor for mortality.

Introduction: Cervical cancer is the fourth most common cancer in women, the highest mortality being found in low- and middle-income countries. Abdominal parietal metastases in cervical cancer are a very rare entity, with an incidence of 0.1–1.3%, and represent an unfavorable prognostic factor with the survival rate falling to 17%. Here, we present a review of cases of abdominal parietal metastasis in recent decades, including a new case of a 4.5 cm abdominal parietal metastasis at the site of the scar of the former drain tube 28 months after diagnosis of stage IIB cervical cancer (adenosquamous carcinoma), treated by external radiotherapy with concurrent chemotherapy and intracavitary brachytherapy and subsequent surgery (type B radical hysterectomy). The tumor was resected within oncological limits with the histopathological result of adenosquamous carcinoma. The case study highlights the importance of early detection and appropriate treatment of metastases in patients with cervical cancer. The discussion explores the potential pathways for parietal metastasis and the impact of incomplete surgical procedures on the development of metastases. The conclusion emphasizes the poor prognosis associated with this type of metastasis in cervical cancer patients and the potential benefits of surgical resection associated with systemic therapy in improving survival rates.

Background: Anastomotic leakage (AL) following rectal cancer surgery is a significant cause of mortality and morbidity. Although transanal drainage tubes are expected to reduce the rate of AL, their preventive effect remains controversial. Aim: To evaluate whether transanal drainage tube (TAD) provides protection against AL in patients without other protective methods after low anterior resection (LAR). Methods: A retrospective cohort study was performed in patients undergoing LAR for rectal cancer between 2018 and 2023. Based on postoperative management, patients were divided into four distinct groups as follows: in TAD group, after colorectal anastomosis, a 32F silicone tube was inserted through the anus by more than 5 cm above the anastomosis. The tube was secured around the anus with a skin suture and a drainage bag was attached. The tube was removed after 3–5 days after surgery. In the non-TAD group, no transanal drainage tube and no diverting stomas, respectively, were used after the anastomosis. In the ileostomy and colostomy group a stoma was often performed as a primary measure in preventing anastomotic leakage. Clinical characteristics and postoperative complications were compared among the groups. Complications were categorized as general (eventration, seroma) or septic (fistula, abscess) and further classified as early (<7 days after surgery) or tardive (between 7 and 30 days after surgery). Statistical significance was defined as a p-value < 0.05. Results: A total of 171 patients were included: 47 (27.5%) in the TAD group, 54 (32.2%) in the non-TAD group, 25 (14.6%) in colostomy group, and 45 (26.3%) in ileostomy group. Overall, eight patients (4.7%) developed anastomotic leakage (AL). In the non-TAD group, 3 patients experienced AL (all early); in the ileostomy group, 2 patients (1 early, 1 tardive); and in the colostomy group, 2 patients (both tardive). The TAD group had one patient with AL as a tardive complication. The incidence of early general complications was significant lower in TAD group compared with the non-TAD group (OR 0.23, 95% CI [0.06–0.85]; p = 0.004), while there was no significant difference in early septic complications between TAD and ileostomy group (p = 0.71). The incidence of tardive general complications was significantly more frequent in the ileostomy group (OR 0.10, 95% CI [0.02–0.44]; p = 0.0008) compared with TAD group. Overall, total complications were significantly lower in TAD group compared to non-TAD (OR 0.15, 95% CI [0.05–0.44]; p < 0.001), ileostomy (OR 0.20, 95% CI [0.07–0.56]; p = 0.003), and colostomy ((OR 0.46 CI [0.21–0.99]; p = 0.049) groups. Furthermore, the TAD group showed a reduction rate of AL compared to the ileostomy, colostomy, and non-TAD groups (2.12% vs. 4.4%, 8%, and 5.5%) but the incidence of AL was almost similar (p = 0.65). Conclusions: The elective use of TAD is a simple and effective protective method for the prevention of overall postoperative complications, also helping to reduce the rate of AL in patients. Nevertheless, there is limited information in the literature regarding the optimal size and material of TAD, despite these factors playing an important role in the viability and effectiveness of the method.
