The latest issue of Cancer Research, Statistics and Treatment contained an interesting article by Michaelraj et al., an epidemiological study on risk factors of head-and-neck squamous cell carcinoma (HNSCC) in south India.[1] I would like to discuss some of the crucial findings of this study and their implications in developing risk stratification models and beyond. This study cross-sectionally analyzed the epidemiological profile of 150 consecutive patients with primary treatment-naïve HNSCC recruited over three years at a tertiary care hospital in Tamil Nadu.[1] As seen in most of the other regions of India, the most common primary site of HNSCC was the oral cavity (40.7%) in this cohort.[2] There were three times more men than women among the diagnosed cases, and only just about a quarter of the study cohort had no exposure to smoking, tobacco chewing, or alcohol (27.3%). Although there existed a significant variability among the men and women regarding the distribution of these risk factors, as per Table 4 in the paper,[1] more than half the men with HNSCC had exposure to multiple risk factors. Furthermore, 66.7% of the overall cohort had exposure to at least one tobacco product. These observations of Michaelraj et al.[1] align with the existing consensus, as they suggest a possible etiopathological role of these known carcinogenic elements, particularly tobacco, the exposure to which is significantly higher among men than women.[3] In Table 5,[1] the authors analyzed the proportional distribution of risk factors in different age groups and found it statistically significant by two-way ANOVA. This table also showed that 91.8% (100/109) of patients with HNSCC exposed to a known risk factor(s) were aged between 41 and 70 years, and only a few patients in the exposed group were outside this range. Additionally, the distribution of all these risk factors (including various combinations of these factors) was seen to peak around the sixth decade of life. Lastly, the patients in the sixth decade of life or older had a higher degree of exposure to multiple risk factors than those in the fifth decade or younger, who had either one risk factor or no exposure at all. All these findings suggest that the putative role of tobacco and alcohol in the carcinogenesis of HNSCC seems to be more relevant in older adults, in their fourth, fifth, and sixth decades of life than in the younger population, a notion that has also been supported by other recent studies.[4] While the relative risk attributable to these known carcinogens is not always predictable, it is understandable that the risk increases with an increase in the duration and severity of exposure to these factors.[5] By these observations, the elderly male with a long-standing use of tobacco, with or without alcohol, would seem to have a higher risk of developing HNSCC, which includes oral cancer. Accordingly, these groups of people, if targeted, would be more likely to benefit from screening programs a
最新一期的《癌症研究、统计和治疗》包含了Michaelraj等人的一篇有趣的文章,这是一篇关于印度南部头颈部鳞状细胞癌(HNSCC)危险因素的流行病学研究。[1]我想讨论一下这项研究的一些重要发现,以及它们对发展风险分层模型和其他方面的影响。本研究横断面分析了在泰米尔纳德邦一家三级医院连续招募的150例原发性treatment-naïve HNSCC患者的流行病学资料。[1]与印度大多数其他地区一样,该队列中最常见的HNSCC原发部位为口腔(40.7%)。[2]在确诊病例中,男性是女性的三倍,只有大约四分之一的研究队列没有吸烟、咀嚼烟草或饮酒(27.3%)。尽管这些危险因素的分布在男性和女性之间存在显著差异,但根据本文的表4,[1]超过一半的HNSCC男性暴露于多种危险因素。此外,整个队列中66.7%的人至少接触过一种烟草制品。Michaelraj等人[1]的这些观察结果与现有的共识一致,因为他们认为这些已知的致癌元素,特别是烟草,可能具有致病病理作用,男性接触烟草的比例明显高于女性[3]。在表5中,[1]作者分析了不同年龄段危险因素的比例分布,经双因素方差分析,发现具有统计学意义。该表还显示,暴露于已知危险因素的HNSCC患者中,年龄在41 - 70岁之间的占91.8%(100/109),暴露组中只有少数患者不在此范围内。此外,所有这些风险因素的分布(包括这些因素的各种组合)在生命的第六个十年左右达到顶峰。最后,60岁或以上的患者暴露于多种危险因素的程度高于50岁或以下的患者,这些患者要么只有一种危险因素,要么根本没有暴露。所有这些发现表明,烟草和酒精在HNSCC癌变中的假定作用似乎与老年人更相关,在他们的第四,第五和第六十岁的生活中,而不是在年轻人中,这一观点也得到了其他近期研究的支持。[4]虽然这些已知致癌物的相对风险并不总是可以预测的,但可以理解的是,风险随着暴露于这些因素的持续时间和严重程度的增加而增加。[5]通过这些观察,长期吸烟或不饮酒的老年男性似乎有更高的患HNSCC(包括口腔癌)的风险。因此,如果有针对性,这些人群将更有可能从筛查项目和预防性干预中受益。[6]通过提供相关风险因素的流行病学概况,Michaelraj等人的研究为开发筛查前风险分层工具奠定了基础,这些工具旨在定义合适的高危人群,他们可以从筛查项目中受益。[6]最近提出了一种名为OraCLE的口腔癌风险分层工具的原型,它基于对风险因素的暴露水平,正在等待验证研究。[7]最后,在这项研究中,人乳头瘤病毒的状况和分布也符合目前的共识,因为在印度,它们只影响一小部分口咽肿瘤。[8,9]总体而言,尽管Michaelraj等人[1]的研究并未在所研究的危险因素与HNSCC之间建立直接的因果关系,但通过在印度南部的一组患者中定义HNSCC的流行病学概况,它可以为这方面的进一步研究奠定基础,并最终有助于设计与研究人群相关的适当筛查和预防策略。财政支持及赞助无。利益冲突没有利益冲突。

While deciding whether to pursue a doctorate of medicine (DM) in Medical Oncology, I talked to numerous people. Most had limited knowledge, some mentioned the potential for significant earnings, others spoke of the emotional toll caused due to the nature of the field, and there were discussions about interdepartmental interference. However, one conversation that particularly stands out is the one I had with a close friend of mine from the United States of America (USA). Dr. DJ Shah left India after completing his Bachelor of Medicine, Bachelor of Surgery (MBBS), to pursue a residency in Internal Medicine in the USA. After finishing his residency, he planned to specialize in Pulmonary Medicine and Critical Care. He explained that he chose critical care because many of the patients he saw were acutely ill. They would either recover and not return, or their condition would deteriorate, and they would pass away. In the latter scenario, an emotional attachment might not be as strong, considering most patients in the intensive care unit (ICU) are intubated, hindering verbal communication, a critical element in forming deep connections. Conversely, he pointed out that oncology presents a different dynamic. Patients you would meet would most likely not be acutely sick, but in a state of shock due to a serious diagnosis. In this field, you would console them, treat them, and accompany them on their journey. Over time, they may be cured or gradually move toward the end of their life. In the latter situation, the experience could be emotionally taxing, both for the family and the treating oncologist, as a personal connection would have been forged during the long journey. He shared a story of a friend at MD Anderson Cancer Center, renowned for cancer treatment in the USA. This friend often struggled with the realization that even at a world-class hospital with exceptional resources, there were cases where treatment fell short, and all that could be done was inform the patient that their time was limited. Despite various perspectives, I ultimately chose to pursue oncology for my DM course. The initial transition was challenging, and I was adapting to a new hospital, environment, and a diverse set of patients. However, I gradually acclimated and found my place. After a month at the Tata Memorial Hospital (TMH, Parel, Mumbai, India), I received the unexpected news that my next two months would be spent at the Advanced Center for Treatment, Research and Education in Cancer (ACTREC) in Kharghar (Navi Mumbai), approximately 35 km from TMH. This facility had a distinct atmosphere, located away from the city’s hustle, offering patients with cancer a serene campus with green spaces and the peace they deserved. They had a building named “Asha Niwas,” which was home to patients with cancer and their families who came for treatment from all over India. During my exploration, I stumbled upon an inauguration stone bearing a name I was familiar with. The name was found in
在决定是否攻读肿瘤医学博士学位(DM)的过程中,我和很多人谈过。大多数人的知识有限,一些人提到了大量收入的潜力,另一些人则谈到了由于该领域的性质而造成的情感损失,还有关于部门间干预的讨论。然而,我和一位来自美国的好朋友的谈话尤其引人注目。Dr. DJ Shah在完成外科医学学士学位(MBBS)后离开印度,前往美国攻读内科住院医师。实习结束后,他计划专攻肺部医学和重症监护。他解释说,他选择重症监护是因为他看到的许多病人都病得很重。他们要么康复而不再回来,要么病情恶化而死去。在后一种情况下,情感依恋可能没有那么强烈,因为大多数重症监护室(ICU)的患者都是插管的,这阻碍了语言交流,而语言交流是形成深度联系的关键因素。相反,他指出肿瘤学呈现出不同的动态。你遇到的病人很可能不是重病,而是由于严重的诊断而处于休克状态。在这个领域,你会安慰他们,对待他们,陪伴他们的旅程。随着时间的推移,他们可能会被治愈或逐渐走向生命的尽头。在后一种情况下,对于家庭和治疗肿瘤的医生来说,这种经历可能是一种情感上的负担,因为在漫长的旅程中,人与人之间的联系是建立起来的。他分享了一个朋友在MD安德森癌症中心的故事,该中心在美国以癌症治疗而闻名。这位朋友经常挣扎于这样一种认识:即使在拥有特殊资源的世界级医院,也会有治疗不足的情况,而所能做的就是告诉病人他们的时间有限。尽管有各种各样的观点,我最终还是选择了肿瘤学作为我的糖尿病课程。最初的过渡是充满挑战的,我要适应新医院、新环境和各种各样的病人。然而,我逐渐适应了环境,找到了自己的位置。在塔塔纪念医院(TMH,帕雷尔,印度孟买)呆了一个月后,我得到了一个意想不到的消息,我接下来的两个月将在哈尔哈尔市(新孟买)的癌症治疗、研究和教育高级中心(ACTREC)度过,距离塔塔纪念医院大约35公里。这个设施有一个独特的氛围,远离城市的喧嚣,为癌症患者提供了一个宁静的校园,有绿色的空间和他们应得的宁静。他们有一座名为“Asha Niwas”的建筑,这里是来自印度各地的癌症患者和他们的家人的家。在探索过程中,我偶然发现了一块就职石,上面有一个我熟悉的名字。在我从医学博士毕业后的许多次火车旅行中,我读过的所有书中都有这个名字:苏达•穆尔蒂(Sudha Murthy),印孚瑟斯基金会(Infosys Foundation)主席。这是一个让我兴奋的时刻,我忍不住拍了一张照片。几天过去了,我开始适应新的工作环境。许多病人在那里寻求治疗。起初,所有的面孔都是新的,但最终,许多人变得熟悉了。在这些面孔中,有一张很显眼——一个二十多岁的年轻人陪着他的母亲。我第一次注意到他是在门诊部(OPD)的房间里听到他说泰米尔语,那里最常用的语言是印地语、马拉地语和英语。他们正在用泰米尔语和我们的泰米尔顾问之一安布医生交谈。虽然我没有直接接触过他们,但随着时间的推移,他们的面孔变得熟悉了。时间流逝,在我的一次夜班中,这些熟悉的人带着担忧的表情来到了事故现场。我称呼她为沙昆塔拉(化名),评估了她的状况。她是一名患有转移性乳腺癌的患者,接受了多种治疗。她出现了高烧,实验室检查显示有中性粒细胞减少症。癌症患者发热性中性粒细胞减少需要及时治疗;否则,他们的病情会迅速恶化。我用英语和印地语解释了情况,让她住进我的病房。在这个过程中,我发现他们说的是马拉雅拉姆语,我的母语,而不是我以为的泰米尔语。然而,我选择不立即透露我的出身。在接下来的几个星期里,沙昆塔拉的病情有所好转,她的发热性中性粒细胞减少症也消失了。查房时,她问我是不是马来亚人。这让我很惊讶,因为我的口音是多年来在说印地语的中央邦和古吉拉特邦养成的。她解释说,我用“La”来称呼她,让她知道了,因为印地语中没有这种特殊的“La”音,而我念她名字的方式只有马来亚人才会有。 这种共同的语言纽带加深了我们之间的联系。我还想知道我们的大脑能够学习多少种语言,因为沙昆塔拉对马拉雅拉姆语、泰米尔语、印地语和英语都很熟悉。她来自帕拉卡德,在著名的高知医院接受了治疗,在多种治疗取得进展后,她转向孟买的TMH。就像许多医生对待自己珍爱的病人一样,我记住了她的细节,甚至是她的病人医院识别码(ID)。她从发热性中性粒细胞减少症中康复后,愉快地出院了。临走前,他们问我要手机号码,我解释说,如果我正忙着处理眼前的病人,可能无法一直接听电话。随着时间的流逝,他们又回到了门诊,为她进行癌症治疗。他们愉快的举止引人注目。每当我们相遇时,就会简短地聊几句。在ACTREC工作两个月后,我回到了帕雷尔TMH的繁华氛围中,恢复了日常工作。一天晚上8点左右,我在查房时接到了一个电话。沙昆塔拉的儿子打电话来了,甚至在接电话之前,我就感觉到有些不对劲。他的声音被泪水压得喘不过气来,起初让人听不懂他在说什么。最后,他告诉我,他的母亲又住院了,这次她病得很重,医生说她的病情很严重。他恳求我和治疗他的医生谈谈,探索任何可能的途径。我的朋友纳赫医生正在监督她的治疗。我立即与他联系,寻求信息。他透露肺转移是问题所在,称她的病情很严峻。从x光片上看,她的肺几乎全被转移瘤覆盖了。他不抱太大希望。我面临着一项艰巨的任务,那就是把这个信息转达给沙昆塔拉的儿子。我倾听他们的担忧,试图安慰他们,并尽可能诚实地解释情况。接下来的两天,我在TMH忙得不可开交。沙昆塔拉一直萦绕在我的脑海里,于是我决定打电话给纳奇医生了解最新情况。由于联系不上他,我就用我记住的病人ID查看了电子病历。输入她的病人号,我发现她已经在那天早上去世了。我不知道该说什么好。悲伤、失望和无助压倒了我。我翻开自己最喜欢的一首诗——朗费罗的《生命赞美诗》,就像我在悲伤时经常做的那样:“你本是尘土,也要归于尘土;这话不是指灵魂。”活在当下,心在内心,上帝在头顶。两天后,当我走在医院附近的街上时,我决定给她的家人发个信息。我发了一条短信,对迟到的消息表示深切的哀悼和遗憾。我转达说,他们竭尽全力帮助她与疾病作斗争。在这艰难的时刻,我为他们的力量祈祷。她的儿子以感激之情回应,感谢我的信息以及我在她住院期间提供的照顾。随着时间的流逝,他们的联系方式被保存了下来,我偶尔会注意到她儿子在WhatsApp上的状态。毫无疑问,他们幸福的小家庭受到了她去世的深刻影响,留下了言语无法填补的空白。当我回顾这段旅程时,我意识到医学不仅仅是治疗疾病;它是关于在人们最脆弱的时刻与他们建立联系。前进的道路充满了挑战和回报,充满了更多的故事要讲,更多的人要牵,更多的人要影响。那么,让我们起来干吧,勇敢地面对任何命运;不断成就,不断追求,学会劳动和等待。——《生命赞美诗》朗费罗财政支持和赞助无。利益冲突没有利益冲突。

We thank Jobanputra,[1] Chauhan and Trivedi,[2] and Devaraja[3] for showing interest in our manuscript, published in the previous issue of the Cancer, Research, Statistics and Treatment journal.[4] The prime objective of our study was to unravel the genetics of head-and-neck squamous cell carcinoma (HNSCC) with special emphasis on the human papillomavirus (HPV). Demographic analysis was performed meticulously as a part of our primary study. As our research was mainly focused on the HPV status of the patient samples, we included only crucial and extensively reported risk factors in our questionnaire (tobacco consumption, smoking, and alcohol). HPV status was identified from the collected patients’ tissue samples in our laboratory as the HPV status of the patients was not available in the medical records. Thus, obtaining information on the HPV status from the patient’s general report would be more informative and would have enabled a wider analysis. HPV testing was performed on all the tissue samples collected, and it was not restricted to a particular subset of cancers, such as oropharyngeal cancers. The results obtained delineated HPV positivity in the oropharyngeal region. Though the sample collection was performed from a single center, we had multiple patients from diverse regions of western Tamil Nadu (Coimbatore, Erode, Salem, Tirupur, Nilgiris, and Dharmapuri). Certain ethical constraints, a limited number of patients reporting to the hospital due to the COVID-19 pandemic, and the unwillingness of the patients to participate in the study were the reasons for not including a larger sample size from diverse centers across Tamil Nadu. Measures are being taken to collect samples from other hospitals and tertiary centers to conduct a large cohort study. In conclusion, we will take the readers’ comments into consideration in the work being continued in our laboratory. Financial support and sponsorship This study was supported by Rashtriya Uchchatar Shiksha Abhiyan (RUSA) under the Bharathiar Cancer and Theranostics Research Center (BCTRC) Scheme. Conflicts of interest There are no conflicts of interest.
我们感谢Jobanputra,[1] Chauhan和Trivedi,[2]和Devaraja[3]对我们发表在上一期《癌症,研究,统计和治疗》杂志上的手稿感兴趣[4]。本研究的主要目的是揭示头颈部鳞状细胞癌(HNSCC)的遗传学,特别强调人乳头瘤病毒(HPV)。人口统计分析是我们初步研究的一部分。由于我们的研究主要集中在患者样本的HPV状态,我们在问卷中只包括了关键的和广泛报道的危险因素(烟草消费、吸烟和饮酒)。由于在医疗记录中没有患者的HPV状态,因此从我们实验室收集的患者组织样本中确定了HPV状态。因此,从患者的一般报告中获得有关HPV状态的信息将提供更多信息,并将使更广泛的分析成为可能。对收集的所有组织样本进行了HPV检测,并且不限于特定的癌症子集,例如口咽癌。所获得的结果描绘了口咽区HPV阳性。虽然样本采集是在一个中心进行的,但我们有来自泰米尔纳德邦西部不同地区(哥印拜陀、罗德、塞勒姆、蒂鲁普尔、尼尔吉里斯和达摩普里)的多名患者。由于某些伦理限制,由于COVID-19大流行而向医院报告的患者数量有限,以及患者不愿意参与研究,这些原因没有包括来自泰米尔纳德邦不同中心的更大样本量。正在采取措施从其他医院和三级医疗中心收集样本,进行大规模队列研究。总之,我们将在实验室继续进行的工作中考虑读者的意见。财政支持和赞助本研究由Rashtriya Uchchatar Shiksha Abhiyan (RUSA)在Bharathiar癌症和治疗研究中心(btrc)计划下支持。利益冲突没有利益冲突。

We thank Mondal et al.[1] and Nagpal et al.[2] for their critical comments on our article, “Gated radiation therapy for patients with breast cancer to reduce the dose to the lung and heart: A comparative cross-sectional study.”[3] The deep inspiratory breath-hold (DIBH) technique reduces radiation dose to the heart in patients with left-sided breast cancer. Many devices are commercially available to conduct treatment via the DIBH technique, like Real-time Position Management Gating solutions from Varian systems and Active Breath Controller (ABC) from Elekta systems. Treatment with ABC involves a mouthpiece that cannot be reused. Thus, before subjecting patients to the DIBH technique-based treatment, we trained the patients with a spirometer to assess if they could hold their breath until two balls were raised in the spirometer. Only then, eligible patients underwent the radiation planning computed tomography simulation scan. In their study, Nagpal et al. measured the cardiac distances from the chest wall as a predictor of percentage reduction in dose to the heart. Irrespective of the distances, if patients can hold their breath, they should be given the benefit of treatment with the DIBH technique rather than the free-breathing technique.[4] In their study, Ferdinand et al., observed the correlation between the heart volume and maximum heart depth in the field as a predictor of cardiac dose reduction via the DIBH technique.[5] Many studies have reported different predictors for cardiac-sparing radiation techniques worldwide. Sardaro et al.[6] estimated that a 1 Gy increase in the mean heart dose equates to a 4% increase in the risk of late heart disease, and Darby et al.[7] estimated that a 1 Gy increase in the mean heart dose causes a 7.4% increase in the rate of major coronary events, like myocardial infarction or death from ischemic heart disease. Chakraborty et al. estimated that the disability-adjusted life years averted would be 622.53 if all Indian patients with left-sided breast cancer (estimated 61,272.65/year) were treated with DIBH. The incremental cost-effectiveness ratio was $4132.90 per disability-adjusted life year, which was 2.11 times the Indian per-capita gross domestic product (2016–2017: $1957.11). Thus, Chakraborty et al. demonstrated that DIBH is cost-effective in developing nations, where cardiac illness is the most prevalent non-communicable disease.[8] Though the mean heart dose of 4.50 ± 0.96 Gy was slightly higher with DIBH in our study[3] compared to other studies, we saw a significant decrease in the mean dose of the heart compared to the free breathing technique.

我们感谢Mondal等人[1]和Nagpal等人[2]对我们的文章《乳腺癌患者的门控制放射治疗以减少对肺和心脏的剂量:一项比较横断面研究》的批评。[3]深吸气屏气(DIBH)技术可以减少左侧乳腺癌患者对心脏的辐射剂量。许多商用设备都可以通过DIBH技术进行治疗,如Varian系统的实时位置管理门控解决方案和Elekta系统的主动呼吸控制器(ABC)。ABC治疗包括一个不能重复使用的牙套。因此,在对患者进行基于DIBH技术的治疗之前,我们用肺活量计训练患者,以评估他们是否可以屏住呼吸,直到肺活量计中的两个球升高。只有这样,符合条件的患者才接受放射计划计算机断层扫描模拟扫描。在他们的研究中,Nagpal等人测量了心脏到胸壁的距离,作为心脏剂量减少百分比的预测指标。不管距离有多远,如果病人能屏住呼吸,他们应该接受DIBH技术而不是自由呼吸技术的治疗。[4]在他们的研究中,Ferdinand等人通过DIBH技术观察到心脏容积和最大心脏深度之间的相关性,作为心脏剂量减少的预测因子。[5]许多研究报告了世界范围内保留心脏的放射技术的不同预测指标。Sardaro等人[6]估计,心脏平均剂量每增加1 Gy,就相当于晚期心脏病风险增加4%;Darby等人[7]估计,心脏平均剂量每增加1 Gy,心肌梗死或缺血性心脏病死亡等主要冠状动脉事件发生率增加7.4%。Chakraborty等人估计,如果所有印度左侧乳腺癌患者(估计为61,272.65/年)接受DIBH治疗,避免的残疾调整生命年将为622.53年。每个残疾调整生命年的增量成本效益比为4132.90美元,是印度人均国内生产总值(2016-2017年:1957.11美元)的2.11倍。因此,Chakraborty等人证明,在心脏病是最普遍的非传染性疾病的发展中国家,DIBH具有成本效益。[8]虽然我们的研究[3]中DIBH的平均心脏剂量为4.50±0.96 Gy略高于其他研究,但与自由呼吸技术相比,我们发现心脏的平均剂量显著降低。尽管如此,我们希望继续将基于DIBH技术的放射治疗的好处给予我们研究所的所有左侧乳腺癌患者。财政支持及赞助无。利益冲突没有利益冲突。

Many devices are commercially available to conduct treatment via the DIBH technique, like Real-time Position Management Gating solutions from Varian systems and Active Breath Controller (ABC) from Elekta systems. Treatment with ABC involves a mouthpiece that cannot be reused. Thus, before subjecting patients to the DIBH technique-based treatment, we trained the patients with a spirometer to assess if they could hold their breath until two balls were raised in the spirometer. Only then, eligible patients underwent the radiation planning computed tomography simulation scan. In their study, Nagpal et al. measured the cardiac distances from the chest wall as a predictor of percentage reduction in dose to the heart. Irrespective of the distances, if patients can hold their breath, they should be given the benefit of treatment with the DIBH technique rather than the free-breathing technique.[4] In their study, Ferdinand et al., observed the correlation between the heart volume and maximum heart depth in the field as a predictor of cardiac dose reduction via the DIBH technique.[5] Many studies have reported different predictors for cardiac-sparing radiation techniques worldwide. Sardaro et al.[6] estimated that a 1 Gy increase in the mean heart dose equates to a 4% increase in the risk of late heart disease, and Darby et al.[7] estimated that a 1 Gy increase in the mean heart dose causes a 7.4% increase in the rate of major coronary events, like myocardial infarction or death from ischemic heart disease.

We thank Kapoor and Mahajan,[1] Fazal et al.,[2] and Gupta and Rangarajan[3] for their keen interest, valuable appreciation, and insightful comments on our article, “Artificial intelligence-based prediction of oral mucositis in patients with head-and-neck cancer: A prospective observational study utilizing a thermographic approach.”[4] We agree with Fazal et al.[1] that, when assessing oral mucositis, it is imperative to give due consideration to the patient’s clinical history and conduct a thorough physical examination. These aspects hold paramount importance in the evaluation process. At the Homi Bhabha Cancer Hospital, Tata Memorial Center, Sangrur, India, we maintain patient records both in the electronic medical record (EMR) system and physical files, while also conducting regular patient examinations. We completely acknowledge the validity of the comment by Fazal et al.[1] that doctors invest significant time in evaluating medical images, and the automation of thermal image processing with the help of artificial intelligence would reduce computational time.[5,6] In the future, more efforts should be made to improve the computational algorithms for larger datasets. We agree with the comments by Kapoor and Mahajan[2] that radiation-induced mucositis takes a minimum of 5–14 days to evolve, and thus, the data acquisition must be done within that specific time slot. Thermal imaging of patients with head-and-neck cancer was conducted over a four-week period as part of a preliminary (pilot) study. Our study[4] was cross-sectional, but thermal data were acquired every week; hence, in many cases, the thermal data were possibly from the same patient in consecutive weeks, but we did not document the data (details) on a weekly basis, which could have provided better clarity to the thermal data. Obtaining real-time data is an extremely time-consuming process, given the concurrent focus on uninterrupted treatment for patients with head-and-neck cancer during the data acquisition phase. The aim of our study[4] was to check the predictability of artificial intelligence-based thermal imaging for oral mucositis. We did not document the clinical aspects. To clarify, we included all cases that received a curative radical radiation dose of 70 Gy; we did not include any patients who received palliative radiotherapy. We agreed with the observation of Gupta and Rangarajan[3] that a larger sample size could have made the deep learning method more sensitive.[7] Real-time thermal data acquisition is a time-consuming process, and data acquisition is still ongoing. In the future, more efforts will be made to improve the computational algorithm on larger thermal datasets that contain images from patients with all grades of mucositis. We thank Gupta and Rangarajan[3] for their recommendations. We will go through the Medical Image Computing and Computer Assisted Intervention Society (MICCAI) and Checklist for Artificial Intelligence in Medical Imaging (CLAIM) checklists a
我们感谢Kapoor和Mahajan,[1] Fazal等人,[2]以及Gupta和Rangarajan[3]对我们的文章“基于人工智能的头颈癌患者口腔黏膜炎预测:一项利用热成像方法的前瞻性观察研究”的强烈兴趣,宝贵的赞赏和深刻的评论。[4]我们同意Fazal等[1]的观点,即在评估口腔黏膜炎时,应充分考虑患者的临床病史,并进行彻底的体格检查。这些方面在评价过程中至关重要。在印度桑古尔塔塔纪念中心的Homi Bhabha癌症医院,我们在电子病历(EMR)系统和物理档案中维护患者记录,同时也对患者进行定期检查。我们完全认可Fazal等人[1]的观点的有效性,即医生在评估医学图像上投入了大量的时间,而借助人工智能实现热图像处理的自动化将减少计算时间。[5,6]未来,更大数据集的计算算法需要进一步改进。我们同意Kapoor和Mahajan[2]的评论,即辐射引起的粘膜炎至少需要5-14天的发展,因此,必须在特定的时间段内进行数据采集。作为初步(试点)研究的一部分,对头颈癌患者进行了为期四周的热成像。我们的研究[4]是横断面的,但每周采集热数据;因此,在许多情况下,热数据可能来自同一患者连续几周,但我们没有以周为单位记录数据(细节),这样可以使热数据更清晰。由于在数据采集阶段同时关注头颈癌患者的不间断治疗,获取实时数据是一个极其耗时的过程。我们研究[4]的目的是检查基于人工智能的口腔黏膜炎热成像的可预测性。我们没有记录临床方面。为了澄清,我们纳入了所有接受70 Gy根治性放射剂量的病例;我们没有纳入任何接受姑息性放疗的患者。我们同意Gupta和Rangarajan[3]的观察,即更大的样本量可以使深度学习方法更加敏感[7]。实时热数据采集是一个耗时的过程,数据采集仍在进行中。在未来,更多的工作将是在更大的热数据集上改进计算算法,这些数据集包含来自所有级别粘膜炎患者的图像。我们感谢Gupta和Rangarajan[3]提出的建议。我们将通过医学图像计算和计算机辅助干预协会(MICCAI)和医学成像人工智能清单(CLAIM)检查清单,并确保我们将其纳入未来的研究。[8,9]我们对他们提出的宝贵建议表示衷心的感谢,我们高度重视这些建议。我们非常感谢大家的投入,并对大家的贡献深表感谢。财政支持及赞助无。利益冲突没有利益冲突。

Educational interventions to improve participation of communities in cancer screening programs 教育干预提高社区对癌症筛查项目的参与
Q1 Medicine Pub Date : 2023-01-01 DOI: 10.4103/crst.crst_224_23
Gokul Sarveswaran, Prashant Mathur
In Ain, France, a low-income, immigrant community with low literacy levels participated in a study by Balamou et al.[1] to evaluate the effects of an eight-week cancer educational intervention on the participants’ screening outcomes, cancer knowledge, and self-efficacy. The study highlighted the importance of targeted educational interventions for populations facing multiple socioeconomic and literacy-related barriers. Vulnerable populations, characterized by factors such as low education, low socioeconomic status, migration, and limited healthcare access, bear a disproportionate burden of cancer incidence and mortality. Additionally, these groups often engage in high-risk behaviors, including tobacco and alcohol use, obesity, physical inactivity, and inadequate consumption of fruits and vegetables, which further elevate their susceptibility to cancer.[2,3] The convergence of socioeconomic disadvantages and these risk factors amplify the vulnerability of these populations to cancer. The study by Balamou et al.[1] sheds light on a crucial topic, given the significant burden of cancer in India and other developing countries and the potential impact of educational interventions. In this editorial, we examine the role of cancer educational interventions in optimizing cancer screening activities, with a specific focus on India’s low literacy population, while referencing similar studies conducted globally to highlight best practices and potential strategies for implementation. Global impact of cancer Cancer is a significant global public health issue, representing the leading cause of death worldwide. In 2020 alone, it accounted for over 10 million deaths, comprising nearly one in six deaths.[4] India, with its vast population and diverse socioeconomic landscape, faces unique challenges in combating cancer. Low literacy rates prevalent among certain segments of the Indian population hinder effective cancer prevention and screening efforts. However, targeted cancer educational interventions present an opportunity to bridge this knowledge gap and empower individuals with the necessary information to make informed decisions. Low literacy rates in India India’s literacy rates have improved over the years, but a considerable portion of the population still faces literacy challenges. According to the National Statistical Office’s 2017–2018 report, the overall literacy rate in India was 77.7%.[5] However, this figure masks regional disparities, with some states reporting literacy rates as low as 66.4%.[6] This low literacy scenario poses a significant barrier to effective cancer prevention and screening initiatives. A study conducted by Tripathi et al.[7] examined the impact of low literacy on cancer knowledge and prevention behaviors in a rural Indian population. The study found that individuals with lower literacy levels had limited awareness of cancer symptoms, risk factors, and the importance of screening. This lack of knowledge contributed to delays in
该研究发现,接受过文化敏感方法培训的社区卫生工作者在传播信息、消除误解、鼓励参与筛查和帮助患者在医疗保健系统中导航方面是有效的。通过与当地领导人、医疗保健提供者和社区组织合作,这种模式可以适应印度的情况。授权社区卫生工作者或志愿者开展互动式会议并提供持续支持,可确保通过干预获得的知识转化为有意义的行动影响和可持续性癌症教育干预措施的影响超出了人们的直接意识。通过优化癌症筛查活动,这些干预措施有助于早期发现,这对于改善治疗结果和降低癌症相关死亡率至关重要Housten等人进行的一项关于癌症教育干预对低识字率人群参与筛查的影响的系统综述显示,教育干预后筛查率显著增加,一些研究报告参与率高达30%。这些发现强调了有针对性的教育项目在提高筛查率和最终减少癌症负担方面的潜力。可持续性是确保长期效益的关键。将癌症教育整合到现有的医疗保健基础设施中,如初级保健中心和社区卫生计划,可以帮助将这些知识融入日常医疗保健服务中。保健专业人员的定期培训和能力建设将提高他们提供准确和可获取信息的能力。利用技术和数字平台可以扩大癌症教育干预的范围移动保健应用程序、基于短消息服务(SMS)的提醒和远程医疗可以为个人提供持续支持和个性化指导,即使在偏远地区也是如此。Hombaiah等人的一项研究表明,通过社会支持团体的参与,移动健康应用程序在提高印度低社会经济地位人群的宫颈癌知识和筛查依从性方面是有效的。该应用程序为社会支持小组的女性成员提供交互式语音响应,并提醒她们筛查预约,从而提高了筛查率,提高了知识留存率。因此,癌症教育干预在优化低识字率人群的癌症筛查活动中起着至关重要的作用。通过调整沟通渠道、简化信息、促进社区参与和确保可持续性,这些干预措施有可能使个人和社区有能力控制自己的健康。通过提高认识和早期发现,我们可以显著减少癌症的负担。要实现这一愿景,必须让各种利益相关者参与进来,包括政府机构、医疗保健提供者、社区领袖和非营利组织。基于循证实践和文化敏感性的合作努力可以为更全面和有效的癌症教育框架铺平道路。对癌症教育干预的投资是对我们人口未来的投资,特别是对那些得不到充分服务的弱势群体的投资。通过优先考虑教育,我们可以创造一个能够更好地预防、检测和治疗癌症的社会,从而改善健康状况。
