Evaluation of the effectiveness and safety of photodynamic therapy in the treatment of precancerous diseases of the cervix (neoplasia) associated with the human papillomavirus: A systematic review.
This study provides an overview of the effectiveness and safety of PDT for the treatment of HPV-associated precancerous cervical conditions and contains recent findings from relevant research studies. A comprehensive literature search of MEDLINE/PubMed, Cochrane Central Library, and Google Scholar was conducted, including analytic epidemiological studies, and 11 papers were included. The narrative synthesis approach was used to summarize the results of the included studies. Studies were critically appraised using The Joanna Briggs Institute (JBI) tool for assessing the risk of bias. The results of the study demonstrate that CRR for HPV remission ranges from 66.7 % to 92.73 %, whereas for CIN1 it fluctuates from 57.1 % to 83.3 %. The frequency of recurrence of the disease ranged from 3.3 % to 8.9 % during the follow-up period of up to 2 years. Adverse events were observed in 8 (66 %) studies and the most common were cervical stenosis, abdominal pain, vaginal pain, and focal edema. Five types of topical and intravenous applications along with lasers of various wavelengths and intensities were mostly used. However, all studies demonstrated relatively similar results. According to the results, PDT has demonstrated favorable outcomes, but no impressive effect on the treatment of CIN. It should be emphasized, that the effectiveness of PDT for the treatment of HPV-associated CIN may vary depending on some variables, including the kind of PDT agent used, the dosage, duration and frequency of PDT administration, the severity and location of the lesions, and the host immunological response.

Efficacy and Safety of Celiac Plexus Neurolysis in the Treatment of Chronic Pain Secondary to Oncological Pathology of the Upper Hemiabdomen: A Systematic Review and Meta-Analysis.
OBJECTIVES
The management of chronic pain among patients with abdominal cancer is complex; against that, the neurolysis of the celiac plexus (CPN) is the best technique at the moment o determine the efficacy and safety in the treatment of chronic pain secondary to oncological pathology of the upper abdomen.
MATERIAL AND METHODS
This was a systematic review of controlled clinical trials between 2000 and 2021, in the sources MEDLINE/PubMed, Cochrane, Scopus, Web of Science, and Google Scholar. Three independent evaluators analysed the results of the bibliographical research. The quality of the studies was assessed with the Jadad scale and the mean difference (95% confidence interval) and heterogeneity of the studies (I2) were calculated with Review Manager 5.3.
RESULTS
Seven hundred and forty-four publications were identified, including 13 studies in the qualitative synthesis and three studies in the quantitative synthesis. No difference was found in the decrease in pain intensity between 1 and 12 weeks after the intervention, comparing the experimental group with the control ( > 0.05). The adverse effects related to neurolysis were not serious and transitory, mentioning the most frequent adverse effects and reporting a percentage between 21% and 67% (with 17% for echoendoscopic neurolysis and 49% for percutaneous neurolysis).
CONCLUSION
Celiac plexus neurolysis for the treatment of severe chronic pain secondary to oncological pathology in the upper hemiabdomen produces similar pain relief as conventional pharmacological analgesic treatment. It is a safe analgesic technique since the complications are mild and transitory.

Review
Intestinal lymphomas can rarely present as abdominal catastrophes with perforation or small bowel obstruction. There is little data regarding their optimal surgical management and associated outcomes. We aimed to systematically review relevant published literature to assess the presentation, diagnosis, optimal surgical approach and associated post-operative outcomes. A systematic on-line literature search of Embase and Medline identified 1485 articles of which 34 relevant studies were selected, including 7 retrospective studies, 1 case series and 26 case reports. Selected articles were assessed by two reviewers to extract data. 95 patients with abdominal catastrophes secondary to lymphoma (predominately Burkitt (28 %) and Diffuse Large B-cell lymphoma (29 %)) were identified with a median age of 52 years, 40 % were female. Of the small bowel resections 25% (n = 18) suffered post-operative complications with a 13.8 % (n = 10) 30-day mortality. Ileocolonic resections had a 27 % complication rate with 18 % mortality and primary repair had a 25 % complications rate and 25 % mortality. Median follow-up was 8 days (range 1-96). Notable points of differences in the presentations between these different lymphomas included the majority of Burkitt's lymphoma were younger, had a known diagnosis, were on chemotherapy and presented with perforation in contrast to those with B cell lymphoma who were predominately older, had new diagnoses and presented with a balanced proportion of obstruction and perforation. Abdominal catastrophes secondary to intestinal lymphomas most commonly present with perforation. Aggressive surgical management, including small bowel resection, may offer similar remission rates for lymphoma patients presenting with abdominal catastrophes as those without such emergency complications.

Meta-Analysis Review
In this review, we aimed to assess the diagnostic performance of ultrasound for assessing the tumor spread in the abdomen in women with ovarian cancer. A search for studies evaluating the role of ultrasound for assessing intrabdominal tumor spread in women with ovarian cancer compared to surgery from January 2011 to March 2023 was performed in PubMed/MEDLINE, Web of Science, and Scopus databases. The Quality Assessment of Diagnostic Accuracy Studies 2 evaluated the quality of the studies (QUADAS-2). All analyses were performed using MIDAS and METANDI commands in STATA 12.0 software. We identified 1552 citations. After exclusions, five studies comprising 822 women were included. Quality of studies were considered as good, except for patient selection as all studies were considered as having high risk of bias. The pooled sensitivity and specificity could be calculated for three anatomical areas (recto-sigma, major omentum and root of mesentery) and the presence of ascites. The pooled sensitivity and specificity for detecting disease in the recto-sigma, major omentum and root of mesentery were 0.83 and 0.95, 0.87 and 0.87, and 0.29 and 0.99, respectively. The pooled sensitivity and specificity for detecting ascites was 0.95 and 0.91, respectively. There is evidence that ultrasound offers good diagnostic performance for evaluating the intra-abdominal extent of disease in women with suspected ovarian cancer.

Meta-Analysis Review
A systematic review of the role of chemotherapy in retroperitoneal sarcoma by the Australia and New Zealand sarcoma association clinical practice guidelines working party.
BACKGROUND
In primary localised resectable retroperitoneal sarcoma (RPS), loco-regional and distant relapse occur frequently despite optimal surgical management. The role of chemotherapy in improving outcomes is unclear.
METHODS
A systematic review was conducted, using the population, intervention, comparison outcome (PICO) model, to evaluate whether neoadjuvant or adjuvant chemotherapy improve outcomes in adults with primary localised resectable RPS. Medline, Embase and Cochrane Central were queried for publications from 1946 to June 2022 that evaluated recurrence free survival, overall survival, and post operative complications. Each study was screened by two independent reviewers for suitability. A qualitative synthesis of the results was performed.
RESULTS
Twenty three studies were identified; one meta-analysis of retrospective studies and 22 retrospective studies including three with propensity matched cohorts. Most studies did not analyse outcomes by histology, detail treatment regimens, provide baseline characteristics or selection criteria for those receiving chemotherapy. Evidence of selection bias was illustrated in several studies. Newcastle-Ottawa quality of retrospective cohort studies was good for 12 studies and poor for 10 studies. All studies were assessed as Level III-2 evidence by the Australian NHMRC hierarchy. Overall, the addition of neoadjuvant or adjuvant chemotherapy to surgery was not associated with improvement in local recurrence, metastasis free survival, disease free survival or overall survival in primary localised resectable RPS. There is some evidence of an association of chemotherapy with worse overall survival. One single centre study showed that neoadjuvant chemotherapy was not associated with increased post operative complications compared to surgery alone in primary localised resectable RPS.
CONCLUSIONS
There is currently no evidence that demonstrates the addition of chemotherapy to surgery improves outcomes in adult patients with primary localised resectable RPS. Available evidence is limited by its retrospective nature and high likelihood of selection bias with chemotherapy generally administered to patients at higher risk of recurrence and many patients not receiving care in high volume sarcoma centres. Randomised trials are required to conclusively determine the role of chemotherapy in primary localised resectable RPS.

Meta-Analysis Review
OBJECTIVE
The investigation of the role of preoperative conization in cervical cancer aiming to explore its potential clinical significance.
DATA SOURCES
Cochrane Library, Embase, PubMed, and Web of Science, up to April 28, 2023.
METHODS OF STUDY SELECTION
(1) Observational cohort studies, (2) studies comparing radical hysterectomy with preoperative conization (CO) vs radical hysterectomy without preoperative conization (NCO) in patients with early-stage cervical cancer, and (3) studies comparing disease-free survival outcomes.
TABULATION, INTEGRATION, AND RESULTS
Two reviewers independently extracted the data and assessed the quality of the studies. The meta-analysis used combined hazard ratios along with their corresponding 95% confidence intervals to compare CO and NCO. We conducted a Bayesian network meta-analysis using Markov chain Monte Carlo methods to compare minimally invasive CO, open CO, minimally invasive NCO, and open NCO. Our study included 15 retrospective trials, 10 of which were used to traditional pairwise meta-analysis and 8 for network meta-analysis. The NCO group exhibited a notably higher probability of cancer recurrence than the CO group (hazard ratio, 0.52; 95% confidence interval, 0.41-0.65). In the network meta-analysis, minimally invasive NCO showed the worst survival outcome.
CONCLUSION
Preoperative conization seems to be a protective factor in decreasing recurrence risk, assisting clinicians in predicting survival outcomes for patients with early-stage cervical cancer. It may potentially aid in selecting suitable candidates for minimally invasive surgery in clinical practice.

Meta-Analysis
BACKGROUND
The diagnostic criteria for abdominal obesity are usually waist circumference or waist-to-hip ratio. The magnitude of the risks for cancers of the digestive system and abdominal obesity is unknown. To assess whether abdominal obesity increases the risk of digestive cancer, we conducted a systematic review and meta-analysis of prospective cohort studies in a database.
METHODS
PubMed, Embase, and Web of Science databases were searched from their inception to December 2022. The 9-star Newcastle Ottawa Scale was used to assess study quality. Pooled relative risks and 95% confidence intervals were calculated using fixed or random effect models respectively. The stability of the results was explored by one-by-one exclusion. Subgroup analysis was conducted to explore sources of heterogeneity. Publication bias was evaluated by Begg's and Egger's tests.
RESULTS
A total of 43 cohort studies were included. There were 42 and 31 studies in the meta-analysis of waist circumference and waist-to-hip ratio on digestive system cancer, respectively. The results of the meta-analysis revealed that the greater waist circumference and waist-to-hip ratio were correlated with increased incidence of digestive system cancers: waist circumference: RR 1.48, 95% CI 1.38-1.59, p < 0.001; waist-to-hip ratio: RR 1.33, 95% CI 1.28-1.38, p = 0.001. Subgroup analysis by cancer type showed that higher WC and WHR would increase the prevalence of LC, PC, GC, EC, and CRC. The sensitivity analysis was conducted by a one-by-one elimination method, and the results of the meta-analysis remained stable. It is proved that the results were robust by the trim-and-fill method.
CONCLUSIONS
There was evidence to suggest that abdominal obesity increased the incidence of digestive cancer, it is necessary to take appropriate measures to reduce abdominal obesity. Waist circumference and waist-to-hip ratio may be better predictors of digestive system cancers. However, the association between waist circumference and digestive system cancer was greater, so more attention should be paid to measuring abdominal obesity with waist circumference.

European Radiology Jun 2024To assess the efficacy and safety of sulfur hexafluoride microbubbles on ultrasound-guided high-intensity focused ultrasound (HIFU) ablation of uterine fibroids. (Meta-Analysis)
Meta-Analysis Review
OBJECTIVES
To assess the efficacy and safety of sulfur hexafluoride microbubbles on ultrasound-guided high-intensity focused ultrasound (HIFU) ablation of uterine fibroids.
METHODS
Studies that compared HIFU-microbubble combination with HIFU-only in patients with uterine fibroids were searched from inception to April 2022. The standardized mean difference (SMD) or relative risk (RR) with 95% confidence interval (CI) for different outcome parameters was calculated.
RESULTS
Seven studies were included, with a total of 901 patients (519 in the combination group and 382 in the HIFU-only group). The energy consumption for treating 1 cm of the lesion in the combination group was less than that in the HIFU-only group [SMD = - 2.19, 95%CI (- 3.81, - 0.57), p = 0.008]. The use of microbubbles was associated with shortening the duration of the treatment and sonication [SMD = - 2.60, 95%CI (- 4.09, - 1.10), p = 0.0007; SMD = - 2.11, 95%CI (- 3.30, - 0.92), p = 0.0005]. The rates of significant greyscale changes during HIFU were greater in the combination group, as well as the increase of non-perfused volume ratio [RR = 1.26, 95%CI (1.04, 1.54), p = 0.02; SMD = 0.32, 95%CI (0.03, 0.61), p = 0.03]. The average sonication durations to reach significant greyscale changes and for ablating 1 cm of the fibroid lesion were shorter in the combination group [SMD = - 1.24, 95%CI (- 2.02, - 0.45), p = 0.002; SMD = - 0.22, 95%CI (- 0.42, - 0.02), p = 0.03]. The two groups had similar post-HIFU adverse effects, while the combination group had fewer intraprocedural adverse events like abdominal pain, sacrum pain, and leg pain.
CONCLUSIONS
Sulfur hexafluoride microbubbles can be safely used to enhance and accelerate the ablation effects of HIFU in the treatment of uterine fibroids.
CLINICAL RELEVANCE STATEMENT
The combination of HIFU with sulfur hexafluoride microbubbles offers a promising non-invasive treatment option for patients with uterine fibroids.
KEY POINTS
• Sulfur hexafluoride microbubbles combined with ultrasound-guided high-intensity focused ultrasound (USgHIFU) has potential advantages in the treatment of uterine fibroids. • Sulfur hexafluoride microbubbles not only enhance the effects of USgHIFU treatment for uterine fibroids but also shorten its duration. • Sulfur hexafluoride microbubbles do not increase the incidence of USgHIFU-related adverse events in the treatment of uterine fibroids.

BACKGROUND
Ewing sarcoma (ES) is a malignant neoplasm of neuroectodermal origin and is commonly observed in children and young adults. The musculoskeletal system is the main body system impacted and ES is rarely seen in the visceral organs particularly the adrenal gland.
AIM
To present a comprehensive review of primary adrenal ES, with emphasis on diagnosis, therapy and oncological outcomes.
METHODS
A systematic review of the literature was performed according to the Preferred Reporting Items for Systematic reviews and Meta-Analyses 2020. PubMed/ MEDLINE, EMBASE and Google Scholar bibliographic databases were searched to identify articles from 1989 to 2022 and included patients with ES/primitive neuroectodermal tumor (PNET) of the adrenal gland. PubMed, Google Scholar and EMBASE medical databases were searched, combining the terms "adrenal", "ES" and "PNET". Demographic, clinical, pathological and oncological data of patients were analyzed by SPSS version 29.0.
RESULTS
A total of 52 studies were included for review (47 case reports and 5 case series) with 66 patients reported to have primary adrenal ES. Mean age at diagnosis was 26.4 ± 15.4 years (37.9% males, 57.6% females, sex not reported in 3 cases). The most frequent complaint was abdominal/flank pain or discomfort (46.4%) followed by a palpable mass (25.0%), and the average duration of symptoms was 2.6 ± 3.1 mo. The imaging modality of choice was computed tomography scan (81.5%), followed by magnetic resonance imaging (20.4%). Preoperative staging revealed that 17 tumors (27.9%) were metastatic and 14 patients had inferior vena cava or renal vein neoplastic thrombus at initial diagnosis. Open adrenalectomy was performed in the majority of cases (80.0%), of which 27.9% required more extensive resection. Minimally invasive surgery was attempted in 8.2% of tumors. Complete surgical resection was achieved in 89.4% of the patients. Adjuvant therapy was administered to 32 patients, in the form of chemotherapy (62.5%), radiotherapy (3.1%) or combination (34.4%). Median overall survival was 15 mo and 24-mo overall survival was 40.5%. Median disease-free survival was 10 mo and 24-mo disease-free survival was 33.3%.
CONCLUSION
The significant progress in molecular biology and genetics of ES does not reflect on patient outcomes. ES remains an aggressive tumor with a poor prognosis and high mortality.
