Background: Renal cell carcinomas (RCCs) are renal parenchymal neoplasms that contribute to <5% of cancer cases worldwide. Within the diverse group of renal tumours, clear cell carcinoma is the most common subtype. The recommended first-line treatment for metastatic disease is a tyrosine kinase inhibitor given either as monotherapy or in combination with an immune checkpoint inhibitor, based on improved survival outcomes. These endpoints are not only influenced by the initial risk stratification but also by certain variables such as the neutrophil-to-lymphocyte (NLR) ratio.

Methods: A retrospective review was conducted to evaluate the progression-free survival (PFS) with first-line treatment in patients with metastatic RCC treated at our institute from the year 2017-2021. We also investigated the association of PFS with both Memorial Sloan Kettering Cancer Center risk groups and the pretreatment NLR ratio.

Results: Overall, 35 patients were enrolled after fulfilling the eligibility criteria. Of these, 25 patients received Pazopanib, 5 patients were treated with Sunitinib and the remaining patients were administered Pembrolizumab with Axitinib. Two-thirds of the study population belonged to the intermediate-risk group. The median PFS for all participants was 16 months. Among the overall population, patients in the favourable-risk group demonstrated superior PFS. Patients with elevated pretreatment NLR experienced shorter PFS compared to the patients with low to normal NLR.

Conclusion: This review highlights the prognostic significance of initial risk stratification and pretreatment NLR in predicting the response to first-line treatment in metastatic RCC patients. As this is a comprehensive study emphasizing the outcomes of metastatic RCC in Pakistan, it fills a void in the literature by providing invaluable perspectives on the real-world outcomes of patients. This not only enhances our understanding of disease management in this region but also lays the foundation for future investigations.

背景:肾细胞癌(RCC肾细胞癌(RCC)是肾实质肿瘤,是导致肾衰竭的原因之一:我们进行了一项回顾性研究,以评估2017-2021年间在我院接受一线治疗的转移性RCC患者的无进展生存期(PFS)。我们还调查了PFS与纪念斯隆-凯特琳癌症中心风险组和治疗前NLR比值的关系:共有35名患者符合资格标准。其中25名患者接受了帕唑帕尼治疗,5名患者接受了舒尼替尼治疗,其余患者接受了Pembrolizumab和Axitinib治疗。三分之二的研究对象属于中危人群。所有参与者的中位PFS为16个月。在所有参与者中,高风险组患者的 PFS 更优。与 NLR 低至正常的患者相比,治疗前 NLR 升高的患者的 PFS 更短:本综述强调了初始风险分层和治疗前 NLR 在预测转移性 RCC 患者对一线治疗反应方面的预后意义。由于这是一项强调巴基斯坦转移性 RCC 患者预后的综合性研究,它填补了文献空白,为患者的实际预后提供了宝贵的视角。这不仅加深了我们对该地区疾病管理的了解,还为今后的研究奠定了基础。

Osteosarcoma is a primary malignant tumour that accounts for less than 1% of cancers diagnosed annually in the United States and 3% of all cancers in paediatric patients. Surgical treatment and adjuvant chemotherapy are essential to improve short- and long-term survival. In this report, we present the case of an 11-month-old female patient referred to the first level of care for a suspected tumour in the left orbit, who underwent biopsy and tumour resection surgery by the maxillofacial surgery service and underwent adjuvant chemotherapy in a specialised centre. Timely detection of cancer in the paediatric population, as well as multidisciplinary management and close surveillance, improves the survival and quality of life of patients.

骨肉瘤是一种原发性恶性肿瘤,在美国每年确诊的癌症中占比不到 1%,在儿科癌症患者中占比 3%。手术治疗和辅助化疗对提高短期和长期生存率至关重要。在本报告中,我们介绍了一名11个月大的女性患者的病例,她因怀疑左眼眶内有肿瘤而被转诊到一级医疗机构,在颌面外科接受了活检和肿瘤切除手术,并在一家专科中心接受了辅助化疗。儿科癌症的及时发现、多学科管理和密切监测提高了患者的生存率和生活质量。

Background: Early detection of ulcerative colitis-associated neoplasia (UC-N) remains a clinical challenge. Identification of molecular biomarkers for colorectal dysplasia and cancer may be extremely beneficial in early detection and managing cancer risk in long-standing ulcerative colitis (UC) patients.

Objective: The aim of this work is to investigate the role of Reg IV in comparison to P53 and KRAS in UC-associated dysplasia and colorectal cancer (CRC) in order to evaluate the potential use of Reg IV for dysplasia and cancer screening in UC patients.

Methods: The study was conducted on 5 groups each 20 colonic endoscopic samples: 1) Normal colonic mucosa, 2) Active UC without dysplasia/carcinoma, 3) UC-associated dysplasia, 4) UC-associated CRC (UC-CRC), 5) Sporadic CRC. All included cases were subjected to Reg IV mRNA expression analysis by quantitative reverse transcription polymerase chain reaction, and immunostaining for Reg IV, P53 and KRAS.

Results: Reg IV mRNA expression levels were found to be significantly higher in groups 3 and 4 (mean: 3.37 and 5.70, respectively). Reg IV immunostaining was highly expressed in groups 3 and 4 (mean: 45.80 and 62.35, respectively). While P53 and KRAS immunostaining was highly expressed in group 5 (mean: 64.57 and 62.90). Furthermore, Reg IV immunoexpression had shown a negative correlation with P53 and KRAS immunoexpression in groups 4 and 5.

Conclusion: Higher expression of Reg IV in patients with UC-dysplasia and UC-CRC versus KRAS and P53 expression in sporadic CRC, suggests a potential role of Reg IV in UC carcinogenesis pathway. This could advocate the use of Reg IV as a screening biomarker for UC-N among patients with long-standing UC as well as a promising targeted therapeutic strategy.

背景:早期检测溃疡性结肠炎相关性肿瘤(UC-N)仍是一项临床挑战。鉴定结直肠发育不良和癌症的分子生物标志物可能对早期发现和控制长期溃疡性结肠炎(UC)患者的癌症风险极为有益:这项工作的目的是研究 Reg IV 与 P53 和 KRAS 相比在 UC 相关性发育不良和结直肠癌(CRC)中的作用,以评估 Reg IV 用于 UC 患者发育不良和癌症筛查的潜力:研究对象为 5 组,每组 20 份结肠内窥镜样本:1)正常结肠粘膜;2)无发育不良/癌的活动性UC;3)UC相关性发育不良;4)UC相关性CRC(UC-CRC);5)散发性CRC。所有纳入病例均通过逆转录聚合酶链式反应定量分析 Reg IV mRNA 表达,并对 Reg IV、P53 和 KRAS 进行免疫染色:结果:发现第 3 组和第 4 组的 Reg IV mRNA 表达水平明显更高(平均值分别为 3.37 和 5.70)。Reg IV 免疫染色在第 3 组和第 4 组表达较高(平均值分别为 45.80 和 62.35)。第 5 组的 P53 和 KRAS 免疫染色表达较高(平均值:64.57 和 62.90)。此外,在第 4 组和第 5 组中,Reg IV 免疫表达与 P53 和 KRAS 免疫表达呈负相关:结论:相对于散发性 CRC 中 KRAS 和 P53 的表达,Reg IV 在 UC 增生异常和 UC-CRC 患者中的表达更高,这表明 Reg IV 在 UC 癌变途径中发挥着潜在的作用。因此,可以将 Reg IV 作为长期溃疡性结肠炎患者中 UC-N 的筛查生物标志物,并作为一种有前景的靶向治疗策略。

Background: Gynaecological cancers, which affect the female genital tract, constitute a significant public health problem, especially in developing countries. Some of these malignancies have known aetiology and premalignant stages making them preventable. Understanding the burden of gynaecological malignancies in our environment will provide baseline information and help form strategies for their control.

Aim: To describe the histological subtypes of gynaecological cancers, their frequency and age distribution trends in Katsina State over the 10-year study period.

Methods: This was a 10-year retrospective cross-sectional multicenter study of all histologically diagnosed gynaecological cancer cases seen from 1st January 2012 to 31st December 2021 at Federal Teaching Hospital Katsina, General Hospital Katsina and General Amadi Rimi Specialist Hospital Katsina. Data for this study were extracted from departmental record registers of the pathology laboratories of the corresponding hospitals whose laboratories provide pathology services to the State. Cancer distribution over the years was sorted based on the primary site of diagnosis, histological diagnosis and age. Data were analysed using Statistical Package for Social Science version 28 and results were presented in tables and charts.

Results: Two thousand three hundred and fifty-nine cancers were seen over the 10-year study period. Of these cases, 58.4% (n = 1,378) were females. Gynaecological malignancies accounted for 18.7% (441/2,359) of all cancers and 32.0% (441/1,378) of all female cancers. The highest frequency of gynaecological cancers was seen in women who were within the age groups of 40-49 and 50-59, and the lowest was seen in women who were ≥90 years old. The mean age was 48.9 ± 14.9 years. The most common site of gynaecological malignancies was the cervix uteri (n = 262, 59.4%) followed by the ovary (n = 106, 24.0%). Other sites in descending order were corpus uteri (n = 29, 6.6%), vulva (n = 9, 2.0%) and vagina (n = 2, 0.5%). The most common histo-morphologic subtypes were large-cell keratinizing squamous cell carcinoma in the cervix, large-cell non-keratinizing squamous cell carcinoma in the cervix and cystadenocarcinoma in the ovary. Choriocarcinoma was found in 33 cases (7.5%).

Conclusion: This study demonstrated the various histotypes of gynaecological malignancies and their trends in Katsina state. The leading cancer was found to be cervical cancer which is mainly preventable. It is hoped that data from this study will provide a basis for making and implementing policies and strategies to lessen the problems of gynaecological malignancies through regular screening programs, especially for cervical cancer and accepting human papilloma virus (HPV) vaccination take-up.

背景:影响女性生殖道的妇科癌症是一个严重的公共卫生问题,尤其是在发展中国家。其中一些恶性肿瘤有已知的病因和恶性前阶段,因此是可以预防的。目的:描述卡齐纳州 10 年间妇科癌症的组织学亚型、发病频率和年龄分布趋势:这是一项为期10年的回顾性横断面多中心研究,研究对象是2012年1月1日至2021年12月31日期间在卡齐纳联邦教学医院、卡齐纳综合医院和卡齐纳阿马迪-里米综合专科医院就诊的所有经组织学诊断的妇科癌症病例。本研究的数据来自为该州提供病理服务的相应医院病理实验室的部门记录登记簿。根据主要诊断部位、组织学诊断和年龄对历年癌症分布情况进行了分类。数据使用社会科学统计软件包第 28 版进行分析,结果以表格和图表的形式呈现:结果:10 年间共发现 2359 例癌症。在这些病例中,58.4%(n = 1 378)为女性。妇科恶性肿瘤占所有癌症的 18.7%(441/2,359),占所有女性癌症的 32.0%(441/1,378)。40-49岁和50-59岁年龄组的妇女患妇科癌症的频率最高,≥90岁的妇女患妇科癌症的频率最低。平均年龄为(48.9 ± 14.9)岁。最常见的妇科恶性肿瘤部位是子宫颈(262 人,59.4%),其次是卵巢(106 人,24.0%)。其他部位依次为子宫颈(29 人,占 6.6%)、外阴(9 人,占 2.0%)和阴道(2 人,占 0.5%)。最常见的组织形态亚型是宫颈大细胞角化性鳞状细胞癌、宫颈大细胞非角化性鳞状细胞癌和卵巢囊肿腺癌。绒毛膜癌有 33 例(7.5%):这项研究显示了卡齐纳州妇科恶性肿瘤的各种组织类型及其发展趋势。发现主要的癌症是宫颈癌,这主要是可以预防的。希望这项研究的数据能为制定和实施政策和战略提供依据,通过定期筛查计划,特别是宫颈癌筛查计划和接受人类乳头瘤病毒(HPV)疫苗接种,减少妇科恶性肿瘤问题。

Hepatocellular carcinoma (HCC) is a lethal malignancy associated with cirrhosis and liver dysfunction. The aim of this study is to characterize a cohort of patients with advanced HCC according to liver function-related variables and evaluate the prognostic significance of Child-Pugh (CP) and albumin-bilirubin (ALBI) scores. A database of 406 HCC patients treated between 2009 and 2023 was retrospectively evaluated. Clinical and laboratory parameters were collected to classify patients into ALBI and CP scores. Survival was estimated using the Kaplan-Meier method and multivariate models were used to evaluate prognosis prediction. In this cohort, 337 (83%) patients were classified as CP-A, while 69 (17%) as CP-B. Additionally, according to ALBI score, 159 (39.2%) individuals were categorised as ALBI-1, 233 (57.4%) as ALBI-2 and 14 (3.4%) as ALBI-3. A statistically significant association between both classifications was observed (p < 0.001). CP and ALBI scores were independently associated with prognosis (Hazard ratio = 2.93 and 1.66, respectively), with better survival for patients with CP-A (versus B) and ALBI-1 (versus -2 and -3). ALBI score showed better predictive performance versus CP (c Harrell´s C index = 0.65 versus 0.62; p = 0.008) and ALBI evolution during the first month of treatment was associated with overall survival. Additionally, ALBI score was able to define distinct prognostic subgroups within CP-A patients. In conclusion, liver function scores, such as ALBI and CP, have a clinically relevant prognostic role in patients with advanced HCC under systemic treatment. ALBI score is a more granular scoring scale than CP, and enables a more precise evaluation of patients with CP-A.

肝细胞癌(HCC)是一种与肝硬化和肝功能异常相关的致命恶性肿瘤。本研究旨在根据肝功能相关变量描述一组晚期HCC患者的特征,并评估Child-Pugh(CP)和白蛋白-胆红素(ALBI)评分的预后意义。我们对2009年至2023年间接受治疗的406名HCC患者的数据库进行了回顾性评估。通过收集临床和实验室参数,将患者分为 ALBI 和 CP 两级。采用卡普兰-梅耶法估算生存率,并使用多变量模型评估预后预测。在该队列中,有 337 例(83%)患者被划分为 CP-A,69 例(17%)被划分为 CP-B。此外,根据 ALBI 评分,159 人(39.2%)被归类为 ALBI-1,233 人(57.4%)被归类为 ALBI-2,14 人(3.4%)被归类为 ALBI-3。这两种分类之间存在明显的统计学关联(P < 0.001)。CP和ALBI评分与预后独立相关(危险比分别为2.93和1.66),CP-A(相对于B)和ALBI-1(相对于-2和-3)的患者生存率更高。与 CP 相比,ALBI 评分显示出更好的预测性能(c Harrell´s C 指数 = 0.65 对 0.62;p = 0.008),治疗第一个月的 ALBI 变化与总生存率相关。此外,ALBI评分还能在CP-A患者中定义不同的预后亚组。总之,ALBI 和 CP 等肝功能评分对接受全身治疗的晚期 HCC 患者具有临床相关预后作用。ALBI 评分比 CP 评分更精细,能对 CP-A 患者进行更精确的评估。

Purpose: Delays in initiating cancer treatment time to treatment initiation (TTI) can negatively impact patient outcomes. This study aimed to quantify the association between TTI and survival in breast, cervical and prostate cancer patients at Inkosi Albert Luthuli Central Hospital (IALCH) in KwaZulu-Natal, South Africa, as a microcosm of Sub-Saharan Africa (SSA).

Methods: We analyzed electronic medical records of patients diagnosed with breast, cervical or prostate cancer at IALCH between 2010 and 2020. Median TTI was calculated for different treatment modalities. To assess the link between treatment delay and mortality, we employed a Cox proportional hazards model to estimate hazard ratios (HRs) and 95% confidence intervals (CIs), treating breast cancer and patients over 40 as competing events. Additionally, Kruskal-Wallis one-way analysis and linear regression were used to compare TTI across racial groups.

Results: The study included patients with breast (44%), cervical (44%) and prostate cancer (12%). Mean age at diagnosis was 62.6, 56.6 and 73.0 years, respectively. Breast cancer patients experienced the longest delays for mastectomy (median 18.4 weeks), followed by prostate cancer patients waiting for radiotherapy (median 16.6 weeks). Significantly longer TTI for radiotherapy was observed in patients younger than 40 with cervical (HR = 2.30, 95% CI: 2.16-2.44, p < 0.001) or prostate cancer (HR = 1.42, 95% CI: 1.03-1.95, p = 0.033) compared to older breast cancer patients. Similar trends were seen for younger patients with cervical cancer receiving chemotherapy. Notably, all racial groups exhibited substantial delays in initiating treatment for all three cancers (breast p < 0.001, prostate p = 0.004 and cervical cancer p < 0.001).

Conclusion: This study identified significant delays in treatment initiation (TTI) for breast, prostate and cervical cancer patients at Inkosi Albert Luthuli Central Hospital (IALCH) in South Africa. These delays were concerning, particularly for younger patients and individuals across all racial backgrounds. Delays in treatment initiation have been linked to increased mortality risk in other studies, highlighting the urgency of addressing this issue. Furthermore, this study serves as a valuable model for future research throughout SSA to collectively address the challenges of treatment delays and improve cancer care for the region.

目的:癌症治疗启动时间(TTI)的延迟会对患者的预后产生负面影响。本研究旨在量化南非夸祖鲁-纳塔尔省 Inkosi Albert Luthuli 中心医院(IALCH)乳腺癌、宫颈癌和前列腺癌患者的 TTI 与生存率之间的关系,以此作为撒哈拉以南非洲(SSA)的缩影:我们分析了 2010 年至 2020 年期间在 IALCH 诊断为乳腺癌、宫颈癌或前列腺癌患者的电子病历。计算了不同治疗方式的中位TTI。为了评估治疗延迟与死亡率之间的联系,我们采用了Cox比例危险模型来估计危险比(HRs)和95%置信区间(CIs),并将乳腺癌和40岁以上的患者作为竞争事件。此外,还使用 Kruskal-Wallis 单向分析和线性回归对不同种族群体的 TTI 进行了比较:研究对象包括乳腺癌(44%)、宫颈癌(44%)和前列腺癌(12%)患者。确诊时的平均年龄分别为 62.6 岁、56.6 岁和 73.0 岁。乳腺癌患者乳房切除术的延迟时间最长(中位数为 18.4 周),其次是前列腺癌患者等待放疗的时间(中位数为 16.6 周)。与年龄较大的乳腺癌患者相比,40 岁以下的宫颈癌(HR = 2.30,95% CI:2.16-2.44,p < 0.001)或前列腺癌(HR = 1.42,95% CI:1.03-1.95,p = 0.033)患者的放疗 TTI 明显更长。接受化疗的年轻宫颈癌患者也有类似趋势。值得注意的是,所有种族群体在三种癌症的开始治疗方面都表现出严重的延迟(乳腺癌 p < 0.001,前列腺癌 p = 0.004,宫颈癌 p < 0.001):本研究发现,南非因科西-阿尔伯特-卢图利中心医院(Inkosi Albert Luthuli Central Hospital,IALCH)的乳腺癌、前列腺癌和宫颈癌患者在开始治疗(TTI)时存在严重延误。这些延误令人担忧,尤其是年轻患者和各种族背景的患者。在其他研究中,延迟开始治疗与死亡率风险的增加有关,这凸显了解决这一问题的紧迫性。此外,这项研究还为整个撒哈拉以南非洲地区未来的研究提供了一个宝贵的模式,以共同应对治疗延误的挑战,改善该地区的癌症治疗。

Background: Globally, acral melanoma (AM) is underrepresented in most clinical trials, being predominant in Caucasian populations. Latin America is a niche that needs to be explored. Therefore, this study aimed to determine the clinical features, response patterns, outcomes and v-raf murine sarcoma viral oncogene homolog B1 (BRAF) status in Peruvian patients with advanced AM.

Methods: We retrospectively reviewed the medical records of 19 patients with advanced AM who received immunotherapy (IO) in first- or subsequent-line therapy. The samples were analysed, and their mutational state was performed by deoxyribonucleic acid sequencing, focusing primarily on the most frequently mutated gene, BRAF. Descriptive statistics were used to assess the baseline characteristics. Overall survival was estimated using the Kaplan-Meier method.

Results: The median age was 64 years and 63.2% were men. Plantar was the site most frequently affected (84.2%). The most frequent stage was stage III (68.4%), with 26.4% receiving adjuvant therapy. The majority of cases exhibited a Breslow thickness of >4 mm (52%), a Clark level of IV/V (89.4%), and all patients presented ulceration and a high range of mitosis. During follow-up, all patients experienced recurrent advanced disease, with 52.6% developing visceral metastasis. Patients who received IO as first or subsequent line had an overall response rate (ORR) of 33.3%, and those who received it as first-line therapy had an ORR of 40%. Twenty-one percent of the patients harbored BRAF V6000E mutation and, showing an ORR of 50% compared to wild-type individuals (44.4%) after the first line of treatment.

Conclusion: Our preliminary study reported that AM has poor clinico-pathological features and response rates to IO in Peruvian patients. However, those who received IO as a first-line treatment or harbored the BRAF mutation appeared to have a slightly better response than wild-type patients.

背景:在全球范围内,尖锐黑色素瘤(AM)在大多数临床试验中的代表性不足,主要发生在白种人群体中。拉丁美洲是一个需要探索的利基市场。因此,本研究旨在确定秘鲁晚期AM患者的临床特征、反应模式、预后和v-raf鼠肉瘤病毒癌基因同源物B1(BRAF)状态:我们回顾性地查看了19名接受免疫疗法(IO)一线或后续治疗的晚期AM患者的病历。对样本进行了分析,并通过脱氧核糖核酸(deoxyribonucleic acid)测序对其突变状态进行了检测,主要侧重于最常见的突变基因 BRAF。描述性统计用于评估基线特征。采用卡普兰-梅耶法估算总生存期:中位年龄为 64 岁,63.2% 为男性。足底是最常受影响的部位(84.2%)。最常见的分期是 III 期(68.4%),其中 26.4% 接受了辅助治疗。大多数病例的布瑞斯洛厚度大于 4 毫米(52%),克拉克水平为 IV/V(89.4%),所有患者均出现溃疡和大量有丝分裂。在随访期间,所有患者的晚期疾病均有复发,52.6%的患者出现了内脏转移。接受 IO 作为一线或后续治疗的患者的总反应率(ORR)为 33.3%,而接受 IO 作为一线治疗的患者的总反应率为 40%。21%的患者携带BRAF V6000E突变,与野生型患者(44.4%)相比,一线治疗后的ORR为50%:我们的初步研究表明,秘鲁患者的临床病理特征和对IO的反应率均较差。然而,接受 IO 作为一线治疗或携带 BRAF 基因突变的患者的反应似乎略好于野生型患者。

Introduction: Lip and oral cavity cancer is the second most frequent cancer in India, accounting for more than 10% of the total cancer incidence in the country. Oral malignancies are frequently found and diagnosed at advanced stages, resulting in dismal survival rates. The influence of healthcare-related factors in the diagnostic interval of oral cancer remains poorly understood.

Methods and material: This study followed the principles of the Aarhus statement for early cancer diagnosis research. Researchers non-selectively recruited 261 patients with histopathologically proven Squamous Cell Carcinoma of the oral cavity at the comprehensive Cancer Care Centre in Northern Kerala, India. They acquired information in direct patient interviews using validated instruments. They triangulated self-reported data with case notes, referral letters and biopsy results.

Results: The median (Interquartile range) diagnostic interval reported by the study participants (n = 261) was 36.00 (14.00-76.50) days. The proportion of participants having diagnostic intervals of more than 30 days was 57.9% (n = 151). The predictors of diagnostic interval include 'Type of advice provided by the health care provider', Number of healthcare providers consulted in the diagnostic journey, 'Age of the participant', 'Monthly income' and 'Caste'.

Conclusion: Nearly three-fifths of the study participants had diagnostic intervals that exceeded the acceptable limit, highlighting the need to streamline the facilities and processes required for early diagnosis of oral cancer. Strengthening the health system at the primary level by incorporating referral guidelines and in-service training of primary care practitioners will reduce diagnostic intervals for oral cancer.

简介唇癌和口腔癌是印度第二大高发癌症,占印度癌症总发病率的 10%以上。口腔恶性肿瘤经常在晚期才被发现和诊断,因此生存率很低。医疗保健相关因素对口腔癌诊断间隔期的影响仍鲜为人知:本研究遵循奥胡斯癌症早期诊断研究声明的原则。研究人员在印度喀拉拉邦北部的综合癌症护理中心非选择性地招募了 261 名经组织病理学证实的口腔鳞状细胞癌患者。他们使用经过验证的工具对患者进行直接访谈,以获取信息。他们将自我报告的数据与病例记录、转诊信和活检结果进行了三角测量:研究参与者(n = 261)报告的诊断间隔中位数(四分位数间距)为 36.00(14.00-76.50)天。诊断间隔超过 30 天的参与者比例为 57.9%(n = 151)。诊断间隔的预测因素包括 "医疗保健提供者提供的建议类型"、诊断过程中咨询的医疗保健提供者数量、"参与者年龄"、"月收入 "和 "种姓":近五分之三的研究参与者的诊断间隔超过了可接受的限度,这突出表明有必要简化口腔癌早期诊断所需的设施和流程。通过纳入转诊指南和对初级保健从业人员进行在职培训来加强初级保健系统,将缩短口腔癌的诊断间隔时间。

Aim: To evaluate the prognostic impact of neutrophil-lymphocyte ratio (NLR), platelet-lymphocyte ratio (PLR) and lymphocyte-monocyte ratio (LMR) on overall survival (OS) among Indian older patients with cancer.

Methods: This observational study was conducted in the geriatric oncology clinic of Tata Memorial Hospital (India). We included all patients who underwent a geriatric assessment (GA) and had a complete blood count available for analysis. The NLR was dichotomized at 3.5, PLR and LMR at the median. Our primary study outcome was OS.

Results: Between June 2018 and November 2021, 786 patients were enrolled (median age: 69 years). The most common primary tumour was lung (308, 39.5%), followed by gastrointestinal (261, 33.5%). Metastatic disease was present in 54.3% of patients. Univariate analysis revealed that patients with NLR >3.5 had shorter OS (9.1 months) than NLR <3.5 (15.7 months) (HR: 1.56). Similarly, patients with PLR >183.5 had reduced OS (9.3 months) compared to PLR <183.5 (16.6 months) (HR: 1.56). Conversely, patients with LMR >3.1 showed better OS (14.2) compared to LMR <3.1 (9.8 months) (HR: 0.74). After adjusting for age, performance status, primary tumour, metastatic status and GA-derived factors (function, nutrition and cognition), NLR (HR: 1.25, 95%CI: 1.03-1.52), PLR (HR: 1.34, 95%CI: 1.11-1.63) and LMR (HR: 0.79, 95%CI: 0.65-0.95) were associated with OS.

Conclusion: In our study of older cancer patients, we identified three key inflammatory markers (NLR >3.5, PLR >183.5, LMR <3.1) as strong predictors of poor OS. These markers remain predictive even after accounting for traditional prognostic factors and GA-derived scales.

Breast cancer poses a significant global health challenge, with higher incidence rates in developed countries. However, low- and middle-income countries (LMICs) suffer from higher mortality rates due to various factors, including limited screening programs, delayed diagnosis and inadequate access to healthcare and advanced treatments. Approximately 5%-10% of breast cancer cases stem from germline mutations in BRCA-1/2 genes. A positive BRCA1/2 status obtained through genetic testing significantly influences surgical and medical treatment decisions. Therefore, genetic counseling, proper surveillance and customized interventions for BRCA1/2 carriers are essential to maximizing the benefits of monitoring, chemoprevention and risk-reducing surgeries for breast and ovarian cancers. Identification of BRCA mutations also impacts treatment strategies, leading to the integration of chemotherapeutic agents like platinum-based chemotherapy and PARP inhibitors. However, implementing these advanced treatment guidelines in LMICs with complex, fragmented and underfunded healthcare systems presents numerous challenges. In this review, we explore the current status and obstacles associated with managing BRCA1/2-associated breast cancer in LMICs.

乳腺癌对全球健康构成重大挑战,发达国家的发病率较高。然而,中低收入国家(LMICs)由于筛查项目有限、诊断延迟、医疗保健和先进治疗手段不足等各种因素,死亡率较高。大约 5%-10%的乳腺癌病例源于 BRCA-1/2 基因的种系突变。通过基因检测获得的 BRCA1/2 阳性状态会对手术和药物治疗决策产生重大影响。因此,为 BRCA1/2 基因携带者提供遗传咨询、适当的监测和量身定制的干预措施,对于最大限度地发挥乳腺癌和卵巢癌监测、化学预防和降低风险手术的益处至关重要。BRCA 基因突变的鉴定也会影响治疗策略,导致化疗药物(如铂类化疗和 PARP 抑制剂)的整合。然而,在医疗保健系统复杂、分散且资金不足的低收入国家和地区实施这些先进的治疗指南面临着诸多挑战。在这篇综述中,我们探讨了在低收入国家和地区管理 BRCA1/2 相关乳腺癌的现状和障碍。
