ObjectivesRadiation-induced oropharyngeal injury is a dose-limiting toxicity in head and neck cancer patients. Delineation of the “oropharyngeal mucosa” and limiting its dose to spare the oropharynx was investigated.MethodsIn this retrospective study, computed tomography imaging from eight patients with previously untreated head and neck cancer was employed. An adaptive contouring brush within the planning software Monaco was used to create an air cavity within the oropharynx, and then the air cavity was expanded uniformly 2 mm to create the “oropharyngeal mucosa”. Three plans were independently generated for each patient: Plan1: dose constraint was applied for the oropharynx; Plan2: dose constraints were applied for the oropharynx and the “oropharyngeal mucosa”; Plan3: dose constraint was applied for the “oropharyngeal mucosa”. T-tests were used to compare the dosimetry variables.ResultsAll plans had adequate target coverage and there were no statistical differences among plans. The mean dose, D30%, D45%, D50%, D85%, D90%, D95%, D100%, V25 Gy, V30 Gy, V35 Gy, V40 Gy, and V45 Gy of the oropharynx and “oropharyngeal mucosa” in Plan1 were significantly higher than those in Plan2 and Plan3. There were no significant differences between Plan2 and Plan3. There were no significant differences in the dosimetric parameters of any other organs at risk.ConclusionDelineation of the “oropharyngeal mucosa” and limiting its dose should be an easy and effective method to spare the oropharynx.

BackgroundCirculating tumor markers with satisfactory sensitivity and specificity play crucial roles in cancer diagnosis and therapy. This prospective study aimed to evaluate the potential of circulating lncRNAs as biomarkers for hepatocellular carcinoma (HCC).MethodsA total of 74 patients with HCC and 94 healthy controls were enrolled. The expression levels of candidate genes in serum were detected by qRT-PCR. Receiver operating characteristic (ROC) curve analysis and logistic regression were employed to investigate the diagnostic capacity of lncRNAs. The analysis of 3-year overall survival (OS) was conducted using the Kaplan-Meier method and log-rank test.ResultsOf the 9 candidate genes, 6 lncRNAs could be stably detected in serum. The expression levels of circulating MALAT1 and HOTTIP in HCC patients were significantly higher than those in controls ( P < 0.001). ROC analysis showed that MALAT1 and HOTTIP were more effective than alpha-fetoprotein (AFP) ( P < 0.010) in the diagnosis of HCC, with AUCs of 0.896 and 0.899, respectively. Additionally, a panel consisting of MALAT1, HOTTIP, and AFP was constructed to obtain an AUC of 0.968 with a sensitivity of 87.8% and specificity of 94.7% in HCC diagnosis. Moreover, the upregulation of MALAT1 was not only related to multiple tumor lesions, HCV infection, AST level, and AFP level, but also suggested shorter OS. A high expression level of HOTTIP was associated with metastasis.ConclusionSerum MALAT1 and HOTTIP play indicative roles as non-invasive biomarkers for HCC.

ObjectivesSurgery is the mainstream treatment for early-stage esophageal squamous cell carcinoma (ESCC) and occult recurrent laryngeal nerve lymph node metastasis (RLNM) is not uncommon among those with R0 resection. The clinical value of postoperative radiotherapy (PORT) in patients with RLNM only is still controversial.MethodsConsecutive patients with early-stage ESCC treated with R0 resection and pathologically confirmed RLNM only from June 2012 to July 2022 were retrospectively reviewed. PORT, covering the supraclavicular and superior mediastinum area (small T-field) at a dose of 50.4 Gy for 28 fractions, was performed in some patients. Propensity score matching (PSM) was performed to balance the baseline characteristics between patients with or without PORT. Pattern of failure, disease-free survival (DFS), and overall survival (OS) were compared.ResultsAmong the 189 patients identified, 69 (35.5%) received PORT and the other 120 (63.5%) did not. After PSM, 154 patients were included in the matched cohort, including 62 in the PORT group and 92 in the non-PORT group. With a median follow-up of 48 (95% CI: 40.3-55.7) months, 69 patients developed their initial disease recurrence in the whole population and PORT significantly decreased the frequency of local recurrence (61.2% vs 21.4%) among those with recurrent disease. Additionally, in the PSM matched cohort, PORT significantly prolonged patients’ DFS (HR 0.393, P = 0.002) and OS (HR 0.462, P = 0.020). Moreover, PORT remained as the independent factor associated with improved DFS (HR 0.360, P = 0.001) and OS (HR 0.451, P = 0.021) after multivariate Cox analyses. In addition, tumor location and pathological TNM stage were found to be independent prognostic factors associated with survival outcomes.ConclusionPORT is associated with improved DFS and OS in ESCC patients with R0 resection and RLNM only, which warrants future validation.

Background and ObjectiveTo investigate the oncologic outcomes of patients with esophageal squamous cell carcinoma (ESCC) who have achieved a pathologic complete response (pCR) of the primary tumor (ypT0) after neoadjuvant chemoradiotherapy (NCRT).MethodsPatients with thoracic ESCC who underwent scheduled NCRT followed by surgery at our hospital between January 2010 and December 2022 were retrospectively analyzed. Only patients with ypT0 disease were enrolled in this study.ResultsA total of 118 patients were ultimately enrolled in this study. Ninety-two patients achieved pCR in the primary tumor and lymph nodes (ypT0N0), while 26 patients had residual metastatic disease in 52 lymph nodes (ypT0N+). Forty-five of the 52 lymph nodes with residual tumors were abdominal lymph nodes. Positive lymph nodes were more often observed in patients with tumors located in the lower third of the esophagus. The 1-, 3-, and 5-year overall survival (OS) rates for the entire study group were 96.5%, 79.5%, and 77.1%, and the 1-, 3-, and 5-year disease-free survival (DFS) rates were 90.5%, 76.8%, and 69.0%, respectively. According to multivariate analyses, pN classification was an independent predictor of both OS and DFS ( P < 0.05), while sex and cT classification were also found to be independent prognostic factors for DFS ( P < 0.05).ConclusionsResidual nodal metastatic disease in patients with ypT0 ESCC after NCRT was more often found in the abdominal lymph nodes. pN classification was an independent predictor of both OS and DFS for ypT0 ESCC patients after NCRT.

Since the introduction of radical prostatectomy by Hugh Hampton Young in 1905, this surgery has undergone constant evolution. With increasing appreciation for the impact of functional preservation on cancer survivorship, urologists have been steadfast in their pursuit of precision surgery to eradicate cancer while maximally preserving the surrounding anatomical structures. In the 1990s and 2000s, the introduction of laparoscopic and robotic prostatectomy brought about welcome improvements including decreased intra-operative blood loss, decreased postoperative pain, shorter hospital length of stay, and faster recovery. Recognizing that focality of prostate cancer lends itself well to precision surgery, robotic surgeons have attempted to exploit the enhanced vision and dexterity provided by the instrument to further improve outcomes. Over the last decade, new techniques have been introduced to help reduce the incidence of incontinence and erectile dysfunction, the 2 most often encountered complications following prostatectomy.

BackgroundAlthough racial disparities in lung cancer incidence and mortality have diminished in recent years, lung cancer remains the second most diagnosed cancer among US Black populations. Many factors contributing to disparities in lung cancer are rooted in structural racism. To quantify this relationship, we examined associations between a multidimensional measure of county-level structural racism and county lung cancer incidence and mortality rates among Black populations, while accounting for county levels of environmental quality.MethodsWe merged 2016-2020 data from the United States Cancer Statistics Data Visualization Tool, a pre-existing county-level structural racism index, the Environmental Protection Agency’s 2006-2010 Environmental Quality Index (EQI), 2023 County Health Rankings, and the 2021 United States Census American Community Survey. We conducted multivariable linear regressions to examine associations between county-level structural racism and county-level lung cancer incidence and mortality rates.ResultsAmong Black males and females, each standard deviation increase in county-level structural racism score was associated with an increase in county-level lung cancer incidence of 6.4 (95% CI: 4.4, 8.5) cases per 100,000 and an increase of 3.3 (95% CI: 2.0, 4.6) lung cancer deaths per 100,000. When examining these associations stratified by sex, larger associations between structural racism and lung cancer rates were observed among Black male populations than among Black females.ConclusionStructural racism contributes to both the number of new lung cancer cases and the number of deaths caused by lung cancer among Black populations. Those aiming to reduce lung cancer cases and deaths should consider addressing racism as a root-cause.
背景虽然近年来肺癌发病率和死亡率的种族差异有所缩小，但肺癌仍是美国黑人中第二大确诊癌症。造成肺癌差异的许多因素都源于结构性种族主义。为了量化这种关系，我们研究了县级结构性种族主义的多维度衡量标准与县级黑人肺癌发病率和死亡率之间的关联，同时考虑了县级环境质量水平。方法我们合并了美国癌症统计数据可视化工具（United States Cancer Statistics Data Visualization Tool）中的 2016-2020 年数据、已有的县级结构性种族主义指数、环境保护署 2006-2010 年环境质量指数（EQI）、2023 年县级健康排名（2023 County Health Rankings）和 2021 年美国人口普查美国社区调查（2021 United States Census American Community Survey）。我们进行了多变量线性回归，以研究县级结构性种族主义与县级肺癌发病率和死亡率之间的关联。结果在黑人男性和女性中，县级结构性种族主义得分每增加一个标准差，县级肺癌发病率就会增加 6.4 例（95% CI：4.4, 8.5）/100,000，肺癌死亡率就会增加 3.3 例（95% CI：2.0, 4.6）/100,000。在按性别对这些关联进行分层研究时，观察到结构性种族主义与肺癌发病率之间的关联在黑人男性人群中比在黑人女性人群中更大。那些旨在减少肺癌病例和死亡人数的人应考虑将种族主义作为根本原因加以解决。

Objective: Precise assessment of spinal instability is critical before and after radiotherapy (RT) for evaluating the effectiveness of RT. Therefore, we retrospectively evaluated the efficacy of RT in spinal instability over a period of 6 months after RT, utilizing the spinal instability neoplastic score (SINS) in patients with painful spinal metastasis. We retrospectively evaluated 108 patients who received RT for painful vertebral metastasis in our institution. Mechanical pain at metastatic vertebrae, radiological responses of irradiated vertebrae, and spinal instability were assessed. Follow-up assessments were done at the start of and at intervals of 1, 2, 3, 4, and 6 months after RT, with the pain disappearing in 67%, 85%, 93%, 97%, and 100% of the patients, respectively. The median SINS were 8, 6, 6, 5, 5, and 4 at the beginning and after 1, 2, 3, 4, and 6 months of RT, respectively. Multivariate analysis revealed that posterolateral involvement of spinal elements (PLISE) was the only risk factor for continuous potentially unstable/unstable spine at 1 month. In conclusion, there was improvement of pain, and recalcification results in regaining spinal stability over time after RT although vertebral body collapse and malalignment occur in some irradiated vertebrae. Clinicians should pay attention to PLISE in predicting continuous potentially unstable/unstable spine.

BackgroundNon-melanoma skin cancer (NMSC) is a frequent type of malignancy with a steadily increasing incidence rate worldwide. Although NMSC was shown to be associated with diabetes, no studies have addressed the extent to which insulin use influences the risk of NMSC in light of social determinants of health (SDOH). We conducted a quantitative study that examined the interplay between insulin use, SDOH, additional covariates, and NMSC among individuals with diabetes.MethodsWe based our analysis on the 2020 Behavioral Risk Factor Surveillance System (BRFSS), a national survey conducted yearly in the US. We performed weighted chi-squared test, logistic regression, and survival analyses on 8685 eligible participants with diabetes enrolled in the BRFSS.ResultsKaplan Meier survival curves showed higher probability of NMSC event-free survival for participants with diabetes using insulin compared to participants with diabetes not using insulin (log-rank test P < .001). Significant associations were detected between insulin use and reduced odds of NMSC (OR .56; 95% CI: .38-.82), and decreased hazard (HR .36; 95% CI: .21-.62), along with indices of SDOH.ConclusionsOur findings suggest that socioeconomic differences related to the healthcare system and behavioral patterns are linked to discrepancies in the use of insulin and the development of NMSC.

Metabolic rewiring is a key feature of cancer cells to support the demands of growth and proliferation. The metabolism of amino acids is altered in many cancers, including pancreatic cancer. The cellular uptake of amino acids is regulated by amino acid transporters, such as L-type amino acid transporter 1 (LAT1). Accumulating evidence suggests that LAT1 is overexpressed in pancreatic cancer and confers a poor prognosis. Here we discuss the prospects of utilizing LAT1 as a novel target for pancreatic cancer therapy.
代谢重构是癌细胞支持生长和增殖需求的一个关键特征。包括胰腺癌在内的许多癌症的氨基酸代谢都发生了改变。细胞对氨基酸的吸收受氨基酸转运体的调节，如 L 型氨基酸转运体 1（LAT1）。越来越多的证据表明，LAT1 在胰腺癌中过度表达，预后不良。在此，我们探讨了利用 LAT1 作为胰腺癌治疗新靶点的前景。

ObjectiveThis study aimed to explore the relationship between CD276 and clear cell renal carcinoma (ccRCC) and assess the diagnostic value of CD276 in ccRCC.MethodsExpression levels of CD276 in ccRCC and para-cancer tissues were compared and analyzed retrospectively using data obtained from TCGA and GEO databases. The clinical data was analyzed prospectively. Immunohistochemistry and RT-PCR analyses were used to analyze the expression of CD276 at the mRNA and protein levels. These analyses compared the expression between ccRCC tissues and para-cancer tissues obtained from 70 patients with ccRCC. Next, ELISA was used to analyze peripheral blood samples from 70 patients with ccRCC and 72 healthy individuals, facilitating the differentiation of ccRCC patients from normal controls. Finally, we utilized the Kaplan-Meier method to generate ROC curves for assessing the diagnostic value of CD276 for ccRCC.ResultsAnalysis of TCGA and GEO data revealed that the mRNA expression of CD276 was higher in ccRCC tissues than in para-cancer tissues ( P < .05). Clinical validation using IHC and RT-PCR confirmed that the expression of CD276 was higher in ccRCC tissues than in para-cancer tissues, both at the mRNA and protein levels ( P < .05). ELISA demonstrated that the expression of CD276 was higher in ccRCC patients than in normal individuals, and patients with a higher pathological grade showed higher expression of CD276 in the peripheral blood than those with a lower pathological grade ( P < .05). ROC curves drawn from the above three datasets demonstrated that CD276 had a high diagnostic value for ccRCC (AUC = .894, .795, .938, respectively).ConclusionThe expression of CD276 was higher in ccRCC tissues and positively associated with the pathological grade. Therefore, CD276 may serve as a molecular biomarker for ccRCC prediction.
