Ovarian Causes of Pseudomyxoma Peritonei (PMP)-A Literature Review.

BACKGROUND: Pseudomyxoma peritonei (PMP) is a rare, progressive, slowly growing, inadequately understood neoplasm with a 5-year progression-free survival rate of as low as 48%. It is characterized by varying degrees of malignancy and the production of mucinous and gelatinous structures. Typically, the development of pseudomyxoma peritonei is associated with the rupture of appendiceal mucinous tumors and other gastrointestinal or ovarian mucinous tumors. The goal of our literature review was to identify various aspects that characterize the ovarian causes of pseudomyxoma peritonei. MATERIALS AND METHODS: The authors performed an extensive literature search between 1 February 2024 and 2 March 2024 on the following databases: Pubmed, Scopus, Oxford Journals, and Reaxys, and the findings were summarized into seven main clinical and paraclinical situations. RESULTS: According to our research, the main instances in which pseudomyxoma peritonei can be triggered by an ovarian cause are the following: (1) mucinous cystadenoma; (2) mucinous ovarian cancer; (3) colon cancer with ovarian metastasis; (4) malignant transformation of an ovarian primary mature cystic teratoma; (5) appendiceal mucocele with peritoneal dissemination mimicking an ovarian tumor with peritoneal carcinomatosis; (6) mucinous borderline tumor developing inside an ovarian teratoma; and (7) the association between a mucinous bilateral ovarian cancer and a colonic tumor. CONCLUSIONS: In our study, we aimed to provide a comprehensive overview of the ovarian causes of pseudomyxoma peritonei, including its epidemiology, imagery characteristics, symptoms, current treatment, and promising future therapies, in the hopes of finding feasible solutions, as a lack of understanding of this mucus-secreting malignant disease increases the risk of delayed diagnosis or uncontrolled deterioration.

Breast Reconstruction following Mastectomy for Breast Cancer or Prophylactic Mastectomy: Therapeutic Options and Results.

(1) Importance of problem: Breast cancer accounted for 685,000 deaths globally in 2020, and half of all cases occur in women with no specific risk factor besides gender and age group. During the last four decades, we have seen a 40% reduction in age-standardized breast cancer mortality and have also witnessed a reduction in the medium age at diagnosis, which in turn means that the number of mastectomies performed for younger women increased, raising the need for adequate breast reconstructive surgery. Advances in oncological treatment have made it possible to limit the extent of what represents radical surgery for breast cancer, yet in the past decade, we have seen a marked trend toward mastectomies in breast-conserving surgery-eligible patients. Prophylactic mastectomies have also registered an upward trend. This trend together with new uses for breast reconstruction like chest feminization in transgender patients has increased the need for breast reconstruction surgery. (2) Purpose: The purpose of this study is to analyze the types of reconstructive procedures, their indications, their limitations, their functional results, and their safety profiles when used during the integrated treatment plan of the oncologic patient. (3) Methods: We conducted an extensive literature review of the main reconstructive techniques, especially the autologous procedures; summarized the findings; and presented a few cases from our own experience for exemplification of the usage of breast reconstruction in oncologic patients. (4) Conclusions: Breast reconstruction has become a necessary step in the treatment of most breast cancers, and many reconstructive techniques are now routinely practiced. Microsurgical techniques are considered the "gold standard", but they are not accessible to all services, from a technical or financial point of view, so pediculated flaps remain the safe and reliable option, along with alloplastic procedures, to improve the quality of life of these patients.

Tips and Tricks for a Successful Literature Review as Part of Medical Career Development.

The literature review is a direct consequence of the increased volume of scientific information, becoming a necessity not only for the medical field. Such material, properly done, is of great use to any professional who wishes to keep abreast of the latest knowledge and concepts. The proposed goal is to help and guide resident doctors, doctoral students, and young researchers in understanding the concepts that are the basis of conducting a literature review and acquiring the generally accepted methodology for conducting it. The selection of information sources, accessing databases, the concept of peer-review, indexing and the impact factor are clearly presented as elements that cannot be neglected in the valorisation of scientific information sources. The structure of a literature review must consider the generally accepted format for such an article, with each chapter having its own importance. Depending on the quality and heterogeneity of the results obtained after analysing the collected data, the review can be structured narratively or systematically, the homogeneity of the results allowing the application of statistical study methods (meta-analysis). Although it seems difficult, conducting a literature review is easier and faster than developing an original study based on experimental or clinical scientific research. The literature review can be carried out in comfortable conditions, online, regardless of location and is a welcome support in the development of the professional and scientific career.

Inequities in Screening and HPV Vaccination Programs and Their Impact on Cervical Cancer Statistics in Romania.

(1) Introduction: A Romanian woman is diagnosed with cervical cancer every two hours; the country ranks second in Europe in terms of the mortality and incidence rate of this disease. This paper aims to identify the main reasons that have led to this situation, focusing on the measures taken by the Romanian Ministry of Health for the prevention of this type of cancer-national programs for cervical cancer screening and HPV vaccination. (2) Materials and methods: We performed a study based on the available secondary data from the National Statistics Institute, World Health Organization and Bucharest Institute of Oncology in order to assess the burden associated with cervical cancer and place it in the context of known global and European incidence and mortality rates, thus evaluating the importance of this health issue in Romania. The second component of our study was a cross-sectional study. Here, we used a 14-question questionnaire applied to the women participating in the National Screening Program for Cervical Cancer and aimed to evaluate the women's level of knowledge about screening and HPV vaccination and their access cervical-cancer-specific healthcare services. (3) Results: The results of this research show that a high percentage of women postpone routine checks due to a lack of time and financial resources and indicate that a low level of knowledge about the disease and the specific preventive methods determines the low participation in screening and HPV vaccination programs implemented in Romania, contributing to the country's cervical cancer situation. (4) Conclusions: The national programs have complicated procedures, are underfunded and do not motivate healthcare workers enough. This, combined with the lack of information for the eligible population, adds up to an extremely low number of women screened and vaccinated. Our conclusion is that the Romanian Ministry of Health must take immediate action by conducting major awareness campaigns, implementing measures to make the programs functional and ensuring coherent funding.

Indocyanine Green (ICG) and Colorectal Surgery: A Literature Review on Qualitative and Quantitative Methods of Usage.

Background: Due to its many benefits, indocyanine green (ICG) has gained progressive popularity in operating rooms (ORs) globally. This literature review examines its qualitative and quantitative usage in surgical treatment. Method: Relevant terms were searched in five international databases (1. Pubmed, 2. Sciencedirect, 3. Scopus, 4. Oxfordjournals, 5. Reaxys) for a comprehensive literature review. The main benefits of using ICG in colorectal surgery are: intraoperative fluorescence angiography; fluorescence-guided lymph node involvement detection and the sentinel technique; the fluorescent emphasis of a minute liver tumour, counting just 200 tumour cells; facilitation of fistula diagnosis; and tumour tattooing. This methodology can also be used with quantitative characteristics such as maximum intensity, relative maximum intensity, and in-flow parameters such as time-to-peak, slope, and t1/2max. This article concludes that fluorescence surgery with ICG and near-infrared (NIR) light is a relatively new technology that improves anatomical and functional information, allowing more comprehensive and safer tumour removal and the preservation of important structures.

Simultaneous Approach of Colo-Rectal and Hepatic Lesions in Colo-Rectal Cancers with Liver Metastasis - A Single Oncological Center Overview.

Introduction: Management of synchronous colorectal cancer with liver metastases (SCLM) is still on debate, regarding timing, indications and complications of the 3 strategies: classic approach (first tumor resection), simultaneous resection and reverse approach (liver first). A retrospective single-centre evaluation of synchronous approach was accomplished, focusing on surgical technique, indications and complications. Material and Methods: Between 2017 and 2020, 31 SCLM patients benefited from synchronously colorectal and hepatic approach: segmental colectomies/rectal resections, simultaneously with liver metastasectomies (associated with radiofrequency ablation). Post-therapeutic imaging monitoring was performed from every 3 - 6 months. There were no perioperative complications related to the combination of the procedures, low morbidity and zero postoperative mortality. Results: The follow-up period was 10 - 40 months: 13 patients had no evidence of recurrence, 10 had hepatic metastases in regression, 4 patients had signs of peritoneal carcinomatosis and 4 showed progression of liver disease; all patients were on chemotherapy. During follow-up 4 patients died. Conclusions: Experience shows that the simultaneous approach of recto-colic and hepatic resections in colo-rectal cancers is a safe procedure, with low morbidity, the limits being dictated by the size of the liver metastases. The results at long-distance must be drawn by further consistent trials.

A Decade of Therapeutic Challenges in Synchronous Gynecological Cancers from the Bucharest Oncological Institute.

The aim of our study is to present the particularities of a specific subset of gynecological cancer patients in Romania. We present a review of synchronous gynecological neoplasia (SGN) treated in the Bucharest Oncological Institute's surgery departments over a decade. Between 2012 and 2022, 7419 female patients with genital malignancies were treated. We identified 36 patients with invasive synchronous primary gynecological cancers (0.5%) and 12 cases with one primary gynecological and another primary invasive pelvic cancer (rectal/bladder). All recurrent, metastatic, or metachronous tumors detected were excluded. Demographic data, personal history, presenting symptoms, pathologic findings, staging, treatment, and evolution for each case were recorded. Usually, the most common SGN association is between ovarian and endometrial cancer of endometrioid differentiation (low-grade malignancies with very good prognosis). However, we noticed that, given the particularities of the Romanian medical system, the most frequent association is between cervical and endometrial, followed by cervical and ovarian cancers. Moreover, the cancer stage at diagnosis is more advanced. In countries with low HPV vaccination rate and low adherence to screening programs, SGNs can present as extremely advanced cases and require extensive surgery (such as pelvic exenterations) to achieve radicality. This multimodal treatment in advanced cases with high tumor burden determines a reduction in survival, time until progression, and quality of life.

Analysis of Efficacy-To-Safety Ratio of Angiogenesis-Inhibitors Based Therapies in Ovarian Cancer: A Systematic Review and Meta-Analysis.

(1) Background: Among new anti-angiogenesis agents being developed and ever-changing guidelines indications, the question of the benefits/safety ratio remains unclear. (2) Methods: We performed a systematic review combined with a meta-analysis of 23 randomized controlled trials (12,081 patients), evaluating overall survival (OS), progression free survival (PFS) and toxicity (grade ≥ 3 toxic effects, type, and number of all adverse effects. (3) Results: The analysis showed improvement of pooled-PFS (HR, 0.71; 95% CI, 0.64-0.78; I2 = 77%; p < 0.00001) in first-line (HR, 0.85; 95% CI, 0.78-0.93; p = 0.0003) or recurrent cancer (HR, 0.62; 95% CI, 0.56-0.70; p < 0.00001) and regardless of the type of anti-angiogenesis drug used (Vascular endothelial growth factor (VEGF) inhibitors, VEGF-receptors (VEGF-R) inhibitors or angiopoietin inhibitors). Improved OS was also observed (HR, 0.95; 95% CI, 0.90-0.99; p = 0.03). OS benefits were only observed in recurrent neoplasms, both platinum-sensitive and platinum-resistant neoplasms. Grade ≥ 3 adverse effects were increased across all trials. Anti-angiogenetic therapy increased the risk of hypertension, infection, thromboembolic/hemorrhagic events, and gastro-intestinal perforations but not the risk of wound-related issues, anemia or posterior leukoencephalopathy syndrome. (4) Conclusions: Although angiogenesis inhibitors improve PFS, there are little-to-no OS benefits. Given the high risk of severe adverse reactions, a careful selection of patients is required for obtaining the best results possible.

The Importance of Route Anatomic Variants of the Common Hepatic Artery.

Introduction: Variants of vascularization in the celiac and upper mesenteric artery are described in the dedicated literature. The anatomy of this area is a subject of interest, considering the potential techniques and the risk of generating intraoperative incidents/accidents or complications. Material and method: We have conducted a unicentric retrospective study, in the Surgery Clinic No.1 of "Prof. Dr. Al. Trestioreanu" Institute of Oncology from Bucharest, on an 11-year interval of time, concerning the occurrence of this rare route-related anomaly of the common hepatic artery, incidence which is evaluated in the dedicated literature at about 0.1%. The study consisted of two components, namely the relevant medical records, on the one hand and focus-group discussions with the 19 surgeons of our department regarding their personal operating experiences, on the other hand. We have identified two cases where this route abnormality of the common hepatic artery, i.e. the retroportal route variant, has been encountered. These two cases are fully documented, including CT-scan and intraoperative images, and they are briefly presented hereinafter. Results: Anatomical variants of the celiac trunk represent an extremely researched topic, considering the major implications in hepato-pancreato-biliary surgery and liver transplantation. Variants of route or origin of the hepatic artery can be the cause of numerous incidents and accidents in hepato-pancreato-biliary oncology surgery, but also in that of trauma. Non-recognition of anatomical, preoperative or intraoperative variants can result in important vascular lesions, especially of the portal vein, which can greatly complicate the resection time. Conclusions: Route variants of the hepatic artery are particularly important in liver transplantation, hepato-pancreato-biliary or gastric oncology surgery, interventional radiology procedures, but also in trauma surgery, especially in case of supramesocolic abdominal penetrating lesions. It would be ideal for these variants to be recognized before surgery, so that the most appropriate surgical technique can be adopted.

The Management of Axillary Lymph Nodes in Breast Cancer - A Retrospective Single-Centre Study.

Introduction: We are presenting the experience of our centre with the surgical treatment of breast cancer, by comparing the use of axillary node dissection with sentinel lymph node biopsy (SNLB). Methods: We have made a retrospective analysis of breast cancer cases in the Surgical Oncology Clinic no. 1, "Alexandru Trestioreanu" Oncology Institute, Bucharest, in the period between December 2019 and December 2020. We are presenting the situations in which axillary node dissection can be replaced with SNLB and the limitations of this method. Results: Although the use of SNLB has advantages compared to axillary node dissection, it is limited by the early detection of breast cancer and by the necessity of adding axillary dissection to surgical treatment in the case of positive SNLB. Conclusions: The replacement of axillary node dissection with SNLB is a desideratum for the following decades in view of an optimal treatment of early-stage breast cancer, with fewer postoperative complications and a better life quality.

Immediate and Long-term Results of Radiofrequency Ablation for Colorectal Liver Metastases.

BACKGROUND/AIM: Radiofrequency ablation (RFA) of colorectal liver metastases (CRLMs) is a method developed in the last 15 years. It provides an acceptable control of the malignant process with lower risks compared to surgical resection. The aim of the study was to assess immediate and long-term results, including recurrence, survival, morbidity/mortality rates after RFA. PATIENTS AND METHODS: Sixty-two cases with CRLMs were treated by RFA during open surgery (89 lesions). Patients were followed-up for a minimum of 36 months, with assessment of recurrences and survival rates at 1, 2 and 3 years, using computed tomography (CT) scan, contrast-enhanced ultrasound and tumor markers (carcinoembryonoc antigen, carbohydrate antigen-19.9). RESULTS: Local relapses, recurrences in other areas and survival rates at 1, 2 and 3 years suggest acceptable values comparative with liver resections in the first 2-3 years and demonstrated long-term limitations, despite the use of adjuvant chemotherapy. Major postoperative negative prognostic factors are tumor multicentricity and tumor's dimensions over 5 cm. CONCLUSION: RFA of CRLMs is a safe procedure with low rates of local relapses and recurrences, as well as acceptable survival rates, in the first 24-36 months post-procedure. It is recommended for patients with no indications for liver resection or having major resection risks.

Digestive Decompression to Prevent Digestive Fistulas After Gastric Neoplasm Resection.

Introduction: The risk of digestive fistula in patients operated for gastric neoplasm is increased due to biological imbalances generated by the cancer's progression, by diagnosis in advanced stages, and by the scale of intervention. Under these circumstances the use of some technical means to protect digestive sutures in these patients is useful. AIM: To analyse the efficiency of technical means to protect the digestive sutures in patients operated in various stages of development of gastric cancer. Material and Methods: We conducted a retrospective study on a group of 130 patients operated for gastric cancer in the 1st General Surgery and Oncology Clinic of the Bucharest Institute of Oncology, between 2010-2014. Results: 38.46% of the patients in the study group presented stage IV cancer with multiple complications and biological imbalances. 52 total gastrectomies and 40 gastric resections were carried out, while in 34 patients palliative "tumour excisions" or other types of palliative surgery were performed. In 15 of the cases with gastric resection a duodenal decompression probe was used, while in 13 of the patients with total gastrectomy an oeso-jejunal aspiration probe together with an oeso-jejunal feeding probe were used as additional technical measures to prevent fistula formation. The incidence of duodenal stump fistula was 7.69%, that of oeso-jejunal anastomosis fistula was 2.3%, with an overall mortality of 3.07% and that of gastro-jejunal anastomosis fistula was 0.76%. CONCLUSION: Given the risk of fistula development in patients with gastric cancer, as well as the increased risk in advanced stages of cancer development, we consider that the use of technical means of protection of digestive sutures is beneficial and opportune, lowering the incidence of fistulas, reducing their output, pathophysiological effects, and mortality.
