Review
BACKGROUND
Acupuncture treatment for tinnitus has received attention owing to its potential as an alternative to conventional treatment modalities. We conducted a scoping review to identify detailed information on acupuncture treatment methods used in clinical studies and to provide useful information for practitioners, patients, and researchers.
METHODS
MEDLINE, Cochrane Central Register of Controlled Trials (CENTRAL), Embase, Oriental Medicine Advanced Searching Integrated System (OASIS), Korean Research Information Sharing Service (RISS), DataBase Periodical Information Academic (DBPIA), and the China National Knowledge Infrastructure (CNKI) were searched from their inception to December 2023. This review included single-arm trials, open-label randomized controlled trials (RCTs), and double-blind RCTs using needle-type acupuncture to treat tinnitus in English, Chinese, and Korean. We investigated basic and detailed information on the acupuncture treatment methods, assessment methods, and study outcomes. Network analysis was also conducted to evaluate the centrality between acupoints in the double-blind RCTs.
RESULTS
We included 106 articles. There were 11 single-arm trials, 90 open-label RCTs, and 5 double-blind RCTs. Most (89.6%) of these studies were conducted in China. Manual acupuncture was the most common type of acupuncture in treatment group. A total of 119 acupuncture points were used 1,138 times. The most frequently used acupoints were local points around the ear (TE17, GB2, SI19, and TE21). Both local and distant acupoints were used simultaneously in these studies. The treatment duration of 20-39 days, 10 to 19 sessions of treatment, the mean acupuncture duration of 30 min, needle diameter of 0.30 mm × 40 mm, and needling depth over 30 mm and less than 50 mm were confirmed as the most common.
CONCLUSION
These study outcomes will enable future acupuncture studies on tinnitus to perform more effective and standardized acupuncture treatments in selecting acupoints and procedures. Furthermore, the study has implications for informing clinicians and students about more impactful acupuncture strategies for addressing tinnitus.

Gynecologic Oncology May 2024To investigate the impact of lymph-vascular space invasion (LVSI) status on the prognosis of endometrial cancer (EC) according to a three-tiered scoring system for LVSI. (Meta-Analysis)
Meta-Analysis Review
OBJECTIVE
To investigate the impact of lymph-vascular space invasion (LVSI) status on the prognosis of endometrial cancer (EC) according to a three-tiered scoring system for LVSI.
METHODS
PubMed, Embase, Cochrane Central Register of Controlled Trials (CENTRAL), International Clinical Trials Registry Platform (ICTRP), and Clinical Trials.gov were searched from inception to September 1st, 2023. The analysis was conducted using STATA 16.0.
RESULTS
A total of 9 studies with 4456 EC patients were included in the analysis. No LVSI was found in 72% of EC patients (95% CI 0.65-0.79), while focal and substantial LVSI were present in 16% (95% CI 0.11-0.21) and 13% (95% CI 0.08-018) of patients, respectively. Compared to the no LVSI group, the focal and substantial LVSI groups had poorer overall survival (for focal LVSI: HR 1.33, 95% CI 1.02-1.74; for substantial LVSI: HR 2.51, 95% CI 1.61-3.90), poorer disease-free survival (for substantial LVSI: HR 2.86, 95% CI 1.21-6.77), and an increased risk of recurrence, including pelvic recurrence (for focal LVSI: HR 2.05, 95% CI 1.03-4.07; for substantial LVSI: HR 6.06, 95% CI 3.31-11.08), distant recurrence (for focal LVSI: HR 2.04, 95% CI 1.42-2.92; for substantial LVSI: HR 3.36, 95% CI 2.35-4.793), and lymph node involvement (for focal LVSI: OR 3.52, 95% CI 1.339.34; for substantial LVSI: OR 5.42, 95% CI 2.78-10.58). Substantial LVSI was more prone to pelvic recurrence (HR 1.82, 95% CI 1.05-3.15) and distant recurrence (HR 2.21, 95% CI 1.48-3.28) than focal LVSI.
CONCLUSIONS
EC patients with focal and substantial LVSI had poorer survival, recurrence, and a higher incidence of lymph node metastasis than patients without LVSI. The substantial LVSI group was associated with even worse prognosis than the focal LVSI group. The three-tiered LVSI scoring system might effectively predict the prognosis of EC and guide clinical decision-making.

Meta-Analysis
BACKGROUND
Head and neck paragangliomas (HNPs) have been associated with gene mutations in the succinate dehydrogenase (SDH) complex, but the clinical significance remains unclear. We sought to explore the demographics, clinical characteristics, treatment methods, and outcomes of SDH-mutated HNPs.
METHODS
Databases were systematically searched. Pooled event ratio and relative 95% confidence intervals were calculated for dichotomous outcomes. Meta-regression was performed. Cochran's Q test and I test assessed heterogeneity. Funnel plot and Egger's regression test assessed publication bias.
RESULTS
Forty-two studies with 8849 patients were included. Meta-regression revealed a significant correlation between multifocality and SDHD mutations (0.03 ± 0.006, p < 0.0001) and between distant metastases and SDHB mutations (0.06 ± 0.023, p = 0.008). There was no correlation between sex, age, tumor size, or familial occurrences and SDH-related mutations.
CONCLUSION
Multifocality of HNPs correlates with the SDHD mutational subtype, and metastases correlate with the SDHB subtype. Knowledge of HNP phenotypes associated with SDH-related mutations has the potential to influence the management approach to such HNPs.

Meta-Analysis
Systematic evaluation and meta-analysis of the prognosis of down-staging human papillomavirus (HPV) positive oropharyngeal squamous cell carcinoma using cetuximab combined with radiotherapy instead of cisplatin combined with radiotherapy.
OBJECTIVE
To evaluate the efficacy and safety of cetuximab instead of cisplatin in combination with downstaging radiotherapy for papillomavirus (HPV) positive oropharyngeal squamous cell carcinoma (HPV OPSCC).
DESIGN
Meta-analysis and systematic evaluation.
DATA SOURCES
The PubMed, Embase, Web of Science, and Cochrane library databases were searched up to June 8, 2023, as well as Clinicaltrials.gov Clinical Trials Registry, China Knowledge Network, Wanfang Data Knowledge Service Platform, and Wiprojournal.com.
ELIGIBILITY CRITERIA FOR SELECTING STUDIES
Randomized controlled trials reporting results of standard regimens of cetuximab + radiotherapy vs cisplatin + radiotherapy in treating HPV OPSCC were included. The primary outcomes of interest were overall survival (OS), progression-free survival (PFS), local regional failure rate (LRF), distant metastasis rate (DM), and adverse events (AE).
DATA EXTRACTION AND SYNTHESIS
Two reviewers independently extracted data and assessed the risk of bias of the included studies. The HR and its 95% CI were used as the effect analysis statistic for survival analysis, while the OR and its 95% CI were used as the effect analysis statistic for dichotomous variables. These statistics were extracted by the reviewers and aggregated using a fixed-effects model to synthesise the data.
RESULTS
A total of 874 relevant papers were obtained from the initial search, and five papers that met the inclusion criteria were included; a total of 1,617 patients with HPV OPSCC were enrolled in these studies. Meta-analysis showed that OS and PFS were significantly shorter in the cetuximab + radiotherapy group of patients with HPV OPSCC compared with those in the conventional cisplatin + radiotherapy group (HR = 2.10, 95% CI [1.39-3.15], = 0.0004; HR = 1.79, 95% CI [1.40-2.29], < 0.0001); LRF and DM were significantly increased (HR = 2.22, 95% CI [1.58-3.11], < 0.0001; HR = 1.66, 95% CI [1.07-2.58], = 0.02), but there was no significant difference in overall grade 3 to 4, acute and late AE overall (OR = 0.86, 95% CI [0.65-1.13], = 0.28).
CONCLUSIONS
Cisplatin + radiotherapy remains the standard treatment for HPV OPSCC. According to the 7th edition AJCC/UICC criteria, low-risk HPV OPSCC patients with a smoking history of ≤ 10 packs/year and non-pharyngeal tumors not involved in lymphatic metastasis had similar survival outcomes with cetuximab/cisplatin + radiotherapy. However, further clinical trials are necessary to determine whether cetuximab + radiotherapy can replace cisplatin + radiotherapy for degraded treatment in individuals who meet the aforementioned characteristics, particularly those with platinum drug allergies.

Review
The gastrin-releasing peptide receptor (GRPR) is known to be overexpressed in breast cancer, making it a promising target for both imaging and therapy within a theranostic framework. Various radioligands targeting GRPR have undergone investigation in preclinical and clinical studies related to breast cancer. This systematic scoping review aimed to assess the current evidence on GRPR-targeted radioligands for diagnostic and therapeutic applications in breast cancer. The methodology followed the PRISMA-ScR protocol. The literature search was conducted in September 2023 and encompassed MEDLINE, Embase, Cochrane, and Scopus databases. We included original peer-reviewed studies focused on breast cancer patients or in vivo breast cancer models. Two reviewers performed the study selection process independently. Data were extracted, synthesized, and categorized into preclinical and clinical studies, further subdivided based on radioligand properties. A total of 35 original studies were included in the review, with three of them evaluating therapeutic outcomes. The results indicated that GRPR-radioantagonists are superior to GRPR-agonists, exhibiting preferable in vivo stability, rapid, specific tumor targeting, and enhanced retention. Both preclinical and clinical evaluations demonstrated renal excretion and high uptake in normal GRPR-expressing tissue, primarily the pancreas. A significant positive correlation was observed between GRPR and estrogen-receptor expression. In the clinical setting, GRPR-radioligands effectively detected primary tumors and, to a lesser extent, lymph node metastases. Moreover, GRPR-targeted radioantagonists successfully identified distant metastases originating from various sites in advanced metastatic disease, strongly correlated with positive estrogen receptor expression. Preclinical therapeutic evaluation of GRPR-radioligands labeled with lutetium-177 showed promising tumor responses, and none of the studies reported any observed or measured side effects, indicating a safe profile. In conclusion, the evidence presented in this review indicates a preference for GRPR-targeted antagonists over agonists, owing to their superior kinetics and promising diagnostic potential. Clinical assessments suggested diagnostic value for GRPR-targeted theranostics in breast cancer patients, particularly those with high estrogen receptor expression. Nevertheless, in the therapeutic clinical context, paying attention to the radiation dose administered to the pancreas and kidneys is crucial.

Review
BACKGROUND
Poorly differentiated thyroid carcinoma (PDTC) is a distinct entity with intermediate prognosis between indolent follicular thyroid cancers and anaplastic carcinoma. The management guidelines are not standardized for these cancers due its low prevalence and limited available literature. Therefore, we did this systematic review with emphasis on current evidence on diagnosis, imaging, molecular markers, and management of these carcinomas.
MATERIALS AND METHODS
We searched four databases, PubMed, Medline, EMBASE, and Emcare to identify studies published till October 2023. All studies reporting diagnostic tests, imaging, molecular marker expression and management of PDTC were included in the review. The meta-analysis was conducted on expression of molecular markers in these cancers following recommendations of the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). Random-effects meta-analysis was used to calculate pooled estimated prevalence with 95% confidence intervals. Based on the inclusion criteria, 62 articles were selected to be incorporated for the review. Differences in pathological diagnostic criteria of PDTC was noted in literature which was addressed in WHO 2022 diagnostic terminologies with expansion of the definition. Surgical management is uniformly recommended for early stage PDTC. However, literature is divided and anecdotal for recommendations on radioactive iodine (RAI), extent of neck dissection and adjuvant treatment in PDTC. Evidence for Next Generation Sequencing (NGS), novel theragnostic approaches, immunotherapy targets are evolving. Based on the subset analysis for expression of molecular markers, we found the most common markers expressed were TERT (41%), BRAF (28%) and P 53 (25%).
CONCLUSION
Poorly differentiated thyroid carcinomas have a high case fatality rate (up to 31%). Eighty-five % of the patients who succumb to the disease have distant metastasis. Even though under-represented in literature, evidence-based management of these aggressive tumors can help personalize the treatment for optimal outcomes.

Meta-Analysis
Malignant carotid body tumors (MCBT) are rare and diagnosed after detection of nodal or distant metastases. This systematic review (SR) focuses on MCBT initially approached by surgery. Preferred Reporting Items for SR and Meta-Analysis (MA) guided the articles search from 2000 to 2023 on PubMed, Scopus, and Web of Science. Among 3548 papers, 132 (337 patients) were considered for SR; of these, 20 (158 patients) for MA. Malignancy rate was 7.3%, succinate dehydrogenase (SDH) mutation 17%, age at diagnosis between 4th and 6th decades, with a higher prevalence of females. MCBTs were mostly Shamblin III, with nodal and distant metastasis in 79.7% and 44.7%, respectively. Malignancy should be suspected if CBT >4 cm, Shamblin III, painful or otherwise symptomatic, at the extremes of age, bilateral, with multifocal disease, and SDHx mutations. Levels II-III clearance should be performed to exclude nodal metastases and adjuvant treatments considered on a case-by-case basis.

Review
OBJECTIVES
Confidence in long-term treatment results of radiofrequency ablation (RFA) for papillary thyroid microcarcinoma (PTMC) is required in comparison with surgery and active surveillance (AS). The objective of this meta-analysis is to report more than three years of follow-up results of radiofrequency ablation for PTMCs.
METHODS
Ovid PUBMED, COCHRANE, and EMBASE databases were searched through Nov 19, 2023, for studies reporting outcomes in patients with PTMC treated with radiofrequency ablation and followed up for more than 3 years. The standard mean difference of the tumor volume before and after therapy, tumor recurrence, lymph node (LN) metastasis, distant metastasis, complications, and the pooled volume reduction rates (VRRs) at 1, 3, 6, 12, 24, 36, and 48 months after radiofrequency ablation were assessed. Data were extracted and methodological quality was assessed independently by two radiologists according to the PRISMA guidelines.
RESULTS
Eight studies, involving 2131 patients, met the inclusion criteria through database searches. The overall VRR was 99.81 % (95 % CI: 99.68, 99.95) in the last follow-up. During a mean pooled follow-up of 46.59 months, 69 patients experienced local PTMC recurrence, with 8 cases within the ablation area. Additionally, 44 patients were diagnosed with newly discovered PTMC, and 17 patients exhibited lymph node metastases. Among the patients with PTMC recurrence, 3 were under active surveillance while 59 underwent additional RFA. The pooled mean complication rate was 2.80 %, with no instances of life-threatening or delayed complications.
CONCLUSIONS
Radiofrequency ablation proves to be an effective local tumor control method for low-risk PTMC patients, resulting in clinically significant and enduring volume reduction. The rate of regrowth and retreatment requirement post-RFA was notably lower, positioning RFA as a compelling alternative to existing treatment options.

BACKGROUND
Neoadjuvant chemoradiotherapy has emerged as the established treatment for locally advanced rectal cancer. Nevertheless, there remains a debate regarding the necessity of adjuvant chemotherapy for patients with locally advanced rectal cancer who exhibit a favorable tumor response (ypT0-2N0) after neoadjuvant chemoradiotherapy and surgery. Thus, the objective of this study is to investigate the impact of adjuvant chemotherapy on the oncological prognosis of rectal cancer patients who have a good response to neoadjuvant chemoradiotherapy.
MATERIALS AND METHODS
The study was conducted following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses protocol. Articles were searched in the Web of Science, PubMed, and Cochrane Library databases. The primary outcomes assessed were 5-year overall survival, disease-free survival, cancer-specific survival, recurrence-free survival, local recurrence, and distant metastasis. The data was summarized using a random effects model.
RESULTS
A meta-analysis was conducted using 18 retrospective studies published between 2009 and 2023. The studies included 9 from China and 5 from Korea, involving a total of 6566 patients with ypT0-2N0 rectal cancer after neoadjuvant chemoradiotherapy. The pooled data revealed that adjuvant chemotherapy significantly improved 5-year overall survival (OR=1.75, 95% CI: 1.15-2.65, P=0.008), recurrence-free survival (OR=1.73, 95% CI: 1.20-2.48, P=0.003), and reduced distant metastasis (OR=0.68, 95% CI: 0.51-0.92, P=0.011). However, adjuvant chemotherapy did not have a significant effect on disease-free survival, cancer-specific survival, and local recurrence in ypT0-2N0 rectal cancer. Subgroup analysis indicated that adjuvant chemotherapy was beneficial in improving overall survival for ypT1-2N0 rectal cancer (OR=1.89, 95% CI: 1.13-3.19, P=0.003).
CONCLUSION
The findings of the meta-analysis suggest that adjuvant chemotherapy may provide benefits in terms of oncological outcomes for rectal cancer patients with ypT0-2N0 after neoadjuvant chemoradiotherapy and radical surgery. However, further prospective clinical studies are needed to confirm these findings.

Dermatology (Basel, Switzerland) 2024Granulomatous mycosis fungoides (GMF) is a rare form of cutaneous T-cell lymphoma characterized by a granulomatous inflammatory infiltrate. (Review)
Review
BACKGROUND
Granulomatous mycosis fungoides (GMF) is a rare form of cutaneous T-cell lymphoma characterized by a granulomatous inflammatory infiltrate.
OBJECTIVE
The impact of granulomatous inflammation on the prognosis of the disease remains controversial as there have been both favorable and unfavorable outcomes documented.
METHODS
We performed a systematic review of 116 GMF cases previously described in the literature.
RESULTS
In contrast to the classic Alibert-Bazin type of mycosis fungoides (MF), cutaneous lesions in GMF tend to involve distal extremities (lower legs, feet, hands) early in the disease course. In the literature, 30% of GMF patients developed organ metastasis, most frequently to the lung. The median time to stage progression was 25 months.
CONCLUSION
GMF is an aggressive form of MF. Therefore, screening for distant metastases should be considered at presentation and repeated during follow-up.
