Epidemiology of cancers among adolescents and young adults from a tertiary cancer center in Delhi

Epidemiology of cancer in adolescents and young adults from a tertiary care hospital in Southern India

PURPOSE

This study aimed to analyze cancer pattern among adolescents and young adults (AYA) in a tertiary care center in South India.

MATERIALS AND METHODS

A retrospective study was undertaken from January 2018 to December 2021 on AYA cancer patients (aged 15-39 years).

RESULTS

Totally, 369 cases of AYA cancers were identified for analyzing the frequency and pattern of cancer distribution. The most common cancers were breast cancer, thyroid cancer, and astrocytoma. All the cancers were more common in males than in females, except for breast, thyroid, gonadal cancers, and unspecified malignant neoplasms.

CONCLUSION

Cancer distribution patterns are distinct among AYA in terms of epidemiology and biology.

A Cross-Sectional Study on the Epidemiology of Newly Diagnosed Breast Cancer Patients Attending Tertiary Care Hospitals in a Tribal Preponderant State of India: Regression Analysis

INTRODUCTION

Breast cancer (BC) is globally prevalent and the leading cause of death due to cancer in females. Due to changes in risk factor profiles, improved cancer registration, and cancer detection, its incidence and death rates have risen over the past three decades. Both modifiable and immutable risk factors for BC make up a sizable portion of the total risk factors.  Methodology: This was a hospital-based cross-sectional study carried out in the Department of Surgery, Rajendra Institute of Medical Sciences (RIMS), Ranchi. Consecutive sampling was done with a complete enumeration of all newly diagnosed cases of breast cancer >15 years old. Those who consented to participate and those who were extremely ill, deaf, or dumb were excluded from the study.

RESULTS

A total of 88 patients were included. Maximum patients diagnosed with breast cancer belonged to the age group of 40-50 years (37.5%), Hindu by religion (76.1%), non-tribal (80.68%), illiterate (89.8%), married (98.9%), housewives (92%), and of class IV socio-economic status (SES) (65.9%).

CONCLUSION

Regular training of Sahiya (the local name of Accredited Social Health Activist (ASHA) in Jharkhand), empowerment of screening clinics for cancer, and upgraded diagnostic facilities for timely referral should be stressed upon.

Controversies and Challenges in the Management of Osteosarcoma-an Indian Perspective

Osteosarcoma (OGS) is the most common primary bone tumor in children and adolescents which requires a multidisciplinary approach to management. Although chemotherapy and surgery can cure more than half of localized OGS cases, the unique challenges faced by resource-limited countries like India make this outcome difficult to achieve. Various questions in the management of OGS including role of high-dose methotrexate (HDMTX) in neoadjuvant setting, triplet vs doublet chemotherapy, intensification of chemotherapy based on response in setting of doublet, and indigenous prosthesis in setting of limb salvage need to be defined. Similarly, in the metastatic and recurrent setting, questions regarding intent of treatment, indications of chemotherapy, timing of surgery, and role of targeted therapies need clarification. Lack of randomized trials from India makes definite conclusions difficult, but an attempt can be made to define the best approach in the Indian scenario from available evidence. Hence, a critical review of literature from India and the West was done to define possible management approaches and highlight the lacuna for future research.

Assessment of Psychological Distress Among Indian Adolescents and Young Adults with Solid Cancer Using the National Comprehensive Cancer Network Distress Thermometer

Purpose The incidence of cancer has increased in India with a visible impact on the young population (aged 15–39 years). The present study aims to evaluate psychological distress among Indian adolescents and young adults (AYAs) with solid cancer using the National Comprehensive Cancer Network (NCCN) distress thermometer.

Methods The demographic and clinical characteristics of AYAs patients (age 15–39 years) with cancer were recorded. Assessment of psychological distress of patients using the NCCN distress thermometer was performed at three time points over a period of 3 months. Distress thermometer scale and a self-administered questionnaire in English and Hindi languages was handed over to participants at three time points: at treatment commencement (T1), at 1 month, and 3 months (T2 and T3, respectively) into therapy.

Results Of the 259 patients, 63% were women and 37% men; the median age was 34 years. In total, 71 (27%) were ≤ 24 years old and 188 (73%) were>24 years old. Bone sarcoma (39%) was common cancer in AYA patients aged ≤ 24 years and breast cancer (21%) in >24 years of age. The distress scores in both the groups were the highest at diagnosis (T1) followed by that measured at 1 (T2) and 3 months (T3) after diagnosis. The distress score in the age ≤ 24 years was the highest (6.7) at T1, followed by those measured at T2 (2.6) and T3 (1.1) and among age>24 years was the highest (6.6) at T1, followed by those measured at T2 (2.6) and T3 (1.2). Among AYA patients>24 years old, worry, nervousness, sadness, transportation, and sleep were the top five identified problems and in ≤ 24 years old, the top identified problems were worry, financial support, sleep, nervousness, and sadness.

Conclusion Adolescents and young adults experience some level of distress associated with the cancer diagnosis, effects of the disease, treatment regardless of the stage and various transitions throughout the trajectory of the disease. The distress thermometer is an easy and useful tool for the assessment of psychological distress in AYA cancers. Early identification of distress burden with the distress thermometer leads to effective interventions in patients with cancer which could improve outcomes including survival in AYAs with cancer in India.

Experiences of Adolescents with Cancer Attending a Tertiary Care Cancer Centre: A Thematic Analysis

Introduction:

Adolescents with cancer experience several psychosocial concerns. Cancer among adolescents contributes to one-fifth of cancers in India. Most of the published empirical literature on adolescents’ views about their cancer experience is from high-income countries.

Objectives:

The objectives of the study were to explore the experiences of adolescents with cancer in India.

Materials and Methods:

Twenty-eight adolescents were purposively recruited and participated in prospectively conducted qualitative interviews conducted at the Tata Memorial Hospital, Mumbai, between 2013 and 2015. Interview data were transcribed and analysed using Braun and Clarke’s reflexive thematic analysis.

Results:

Two themes and several subthemes were generated during the analysis. The transition to the new reality of illness was traumatic. It embodied fear about the unknown, disease and symptoms. The experience was isolating and disfigurement further led to peer separation. Inadequate information made the adolescents anxious and worried, and children and parents experienced moments of severe distress. The love and support received from parents, siblings and extended family facilitated positive coping. Peer support was reassuring and enabled them to have a normalising experience. Discovering their inner strength, acceptance of the situation and faith in God made them resilient and hopeful.

Conclusion:

Adolescents with cancer experience significant emotional concerns, which are often unexplored and unaddressed. An adolescent-specific communication framework and psychosocial programme contextual to the Indian setting may be developed based on the study findings.

Adolescent and young adult cancers in India-Findings from the National Cancer Registry Programme

BACKGROUND

The adolescent and young adult (AYA) age group is a bridge between pediatric and adult age groups. The present study describes the epidemiology of cancers in the AYA age group in India.

METHODS

The data of primary site cancers in the age group of 15-39 years from the 28 Population Based Cancer Registries (PBCRs') and 58 Hospital Based Cancer Registries under the National Cancer Registry Programme for the reporting year 2012-2016 was analysed.

RESULTS

The median age adjusted incidence rate (AAR) was 22.2 per 100,000 among males and 29.2 per 100,000 among females. The age-specific incidence rate increased with increasing age in both genders with the highest recorded numbers in the 35-39 age group. The proportion of myeloid leukaemia and non-Hodgkin's lymphoma was highest in the 15-24 age group. Cancers of the breast, thyroid, mouth and tongue constituted the leading sites between 30 and 39 years. There was a significant increase in the incidence among AYA males (APC=0.9) between 1985 and 2015, while a decline in incidence was observed for females, which was not significant (APC=-0.2). The majority of patients had locoregional spread of cancer at the time of diagnosis. The projected number of cancer cases in both genders are expected to increase to 178,617 in 2025.

CONCLUSION

Cancers in the AYA population are a concern in India. Since AYA oncology appears to be evolving in India, a robust health care system and suitable AYA cancer care policies and programmes are strongly needed to improve disease outcomes and survival.

Cancer in the Adolescent and Young Adults (AYA) and Children: A Comprehensive Analysis of the Epidemiology and Psychosocial Morbidity in the Indian Population

Aims  Adolescent and young adults (AYAs), children with cancer, and their guardians have unique psychosocial morbidities adversely effecting quality of life (QOL). This is measurable using patented tools. We analyzed epidemiological and clinicopathological patterns of solid organ cancers in this subgroup. We also assessed psychosocial morbidity and changes in QOL faced by them.

Methods  All patients aged 2 to 39 years, newly diagnosed with cancer from April 2017 to March 2019 were included. Clinical history, diagnosis, staging, treatment, outcomes, and follow-up were recorded. The National Comprehensive Cancer Network (NCCN) distress thermometer and European Organization for Research and Treatment of Cancer Quality of Life Questionnaire (EORTC QLQ C-30) were used to assess psychosocial morbidity of AYAs, children ≥ 12 years, and parents of children < 12 years. Pediatric Quality of Life Inventory (Peds QL) version 3.0 was used for children < 12 years. Data was analyzed using descriptive statistics.

Results  A total of 571 patients (512 AYAs, 59 children) were enrolled. Median age was 30 years with male predominance (58.1%). Most cases (98.6%) were absent from school or work. Carcinoma breast was the most common in females (29.3%) and non-Hodgkin lymphoma in males (12.6%). 91.06% had overall NCCN distress score ≥ 4. Also, 73.81 and 79.49% had “quite a bit” or “very much” responses on functional and symptom scales, respectively, in EORTC QLQ C-30 questionnaire. Peds QL version 3.0 revealed total score ranging from 276 to 523 for each patient.

Conclusion  AYAs and children with cancer are extremely vulnerable to psychological stress and morbidity. Use of well-established tools help in assessing their mental status and timely psychiatric referral can be initiated.

Web-based nomograms for predicting the prognosis of adolescent and young adult skin melanoma, a large population-based real-world analysis

Background

Invasive cutaneous melanoma is one of the most common malignant diseases among adolescents and young adults (aged 15–40 years) in the United States. We aimed to develop web-based nomograms to precisely predict overall survival and cancer-specific survival in this group of patients with cutaneous melanoma.

Methods

We analyzed the overall and caner-specific death events in 19,887 patients who underwent surgical resection of cutaneous melanoma from Surveillance, Epidemiology and End Results database and developed web-based clinic-pathologic prediction models for overall survival and cancer specific survival based on Cox regression. C-statistics of Harrell and time-dependent Receiver Operating Characteristic Curve (ROC) were used to evaluate the prognostic accuracy of nomograms.

Results

Multivariate Cox regression model analysis suggested that age, sex, race, tumor location, Clark level, ulceration, thickness, and N stage were independently associated with both overall survival and cancer-specific survival in adolescent and young adult patients with cutaneous melanoma. The nomograms performed excellently in predicting overall survival and cancer-specific survival with C-index being 0.875 (95% CI: 0.847–0.903) and 0.901 (95% CI: 0.876–0.925), respectively. Time-dependent ROC verified that the prognostic accuracy of nomograms was better than that of American Joint Committee on Cancer staging system and other prognostic factors.

Conclusions

These user-friendly nomograms can precisely predict overall survival and cancer-specific survival in cutaneous melanoma patients treated with surgical resection, which may help to make individualized postoperative follow-up and therapeutic schemes.

Aerobic fitness in late adolescence and the risk of cancer and cancer-associated mortality in adulthood: A prospective nationwide study of 1.2 million Swedish men

BACKGROUND

The incidence of cancer has steadily risen. It is important to identify modifiable predictors in early life that may decrease cancer risks and mortality. The present study aims to investigate the relationship between aerobic fitness in adolescence and the subsequent risk of cancer and cancer-associated mortality.

METHODS

The study included 1 185 439 Swedish men born between 1950 and 1980 that participated in the military conscription (mean age = 18 years). The results from the aerobic fitness test (W_max) was linked to the risk of cancer and cancer-associated mortality during a 40-years' follow-up using Cox proportional hazards models. A co-sibling design was employed to take familial factors into account.

RESULTS

During a mean follow-up of 27 years 15 093 cases of cancer and 4900 cancer-associated mortalities were registered. Higher W_max (per additional 1 SD) was associated with a decreased risk of cancer at 40 years of follow-up (HR 0.93; 95% CI 0.91-0.96 for cancer and HR 0.82 95% CI 0.76-0.87 for cancer-associated mortality) but not at 5 years of follow-up (HR 1.03; 95% CI 0.99-1.07; and HR 1.04; 95% CI 0.97-1.12). In the co-sibling model the protective effects of high W_max were increased at 40 years of follow-up for cancer (HR 0.91; 95% CI 0.85-0.98) and cancer-associated mortality (HR 0.78; 95% CI 0.68-0.89).

CONCLUSIONS

These findings identify in late adolescence a potentially modifiable predictor of cancer, with higher aerobic fitness associated with a decreased risk of cancer incidence and mortality later in life.

The burden of cancers and their variations across the states of India: the Global Burden of Disease Study 1990-2016

Background

Previous efforts to report estimates of cancer incidence and mortality in India and its different parts include the National Cancer Registry Programme Reports, Sample Registration System cause of death findings, Cancer Incidence in Five Continents Series, and GLOBOCAN. We present a comprehensive picture of the patterns and time trends of the burden of total cancer and specific cancer types in each state of India estimated as part of the Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) 2016 because such a systematic compilation is not readily available.

Methods

We used all accessible data from multiple sources, including 42 population-based cancer registries and the nationwide Sample Registration System of India, to estimate the incidence of 28 types of cancer in every state of India from 1990 to 2016 and the deaths and disability-adjusted life-years (DALYs) caused by them, as part of GBD 2016. We present incidence, DALYs, and death rates for all cancers together, and the trends of all types of cancers, highlighting the heterogeneity in the burden of specific types of cancers across the states of India. We also present the contribution of major risk factors to cancer DALYs in India.

Findings

8·3% (95% uncertainty interval [UI] 7·9–8·6) of the total deaths and 5·0% (4·6–5·5) of the total DALYs in India in 2016 were due to cancer, which was double the contribution of cancer in 1990. However, the age-standardised incidence rate of cancer did not change substantially during this period. The age-standardised cancer DALY rate had a 2·6 times variation across the states of India in 2016. The ten cancers responsible for the highest proportion of cancer DALYs in India in 2016 were stomach (9·0% of the total cancer DALYs), breast (8·2%), lung (7·5%), lip and oral cavity (7·2%), pharynx other than nasopharynx (6·8%), colon and rectum (5·8%), leukaemia (5·2%), cervical (5·2%), oesophageal (4·3%), and brain and nervous system (3·5%) cancer. Among these cancers, the age-standardised incidence rate of breast cancer increased significantly by 40·7% (95% UI 7·0–85·6) from 1990 to 2016, whereas it decreased for stomach (39·7%; 34·3–44·0), lip and oral cavity (6·4%; 0·4–18·6), cervical (39·7%; 26·5–57·3), and oesophageal cancer (31·2%; 27·9–34·9), and leukaemia (16·1%; 4·3–24·2). We found substantial inter-state heterogeneity in the age-standardised incidence rate of the different types of cancers in 2016, with a 3·3 times to 11·6 times variation for the four most frequent cancers (lip and oral, breast, lung, and stomach). Tobacco use was the leading risk factor for cancers in India to which the highest proportion (10·9%) of cancer DALYs could be attributed in 2016.

Interpretation

The substantial heterogeneity in the state-level incidence rate and health loss trends of the different types of cancer in India over this 26-year period should be taken into account to strengthen infrastructure and human resources for cancer prevention and control at both the national and state levels. These efforts should focus on the ten cancers contributing the highest DALYs in India, including cancers of the stomach, lung, pharynx other than nasopharynx, colon and rectum, leukaemia, oesophageal, and brain and nervous system, in addition to breast, lip and oral cavity, and cervical cancer, which are currently the focus of screening and early detection programmes.

Epidemiology of cancer in young in central India: An analysis of rural cancer hospital data

Background:

Cancers in teenage and young adults (TYAs), though an increasing cause of mortality in our country, have been scarcely studied. The lack of studies of TYAs can significantly affect the outcomes of the youth in the prime of their lives.

Aims:

The aim of this study was to study the type of cancers in the TYA at a rural cancer center in central India.

Design and Methods:

A prospective study in the department of medical oncology, from the period of January 2013 till March 2016, was done. Data regarding socioepidemiological factors were collected for new cancer patients between the age group of 15–30 years in semi-structured questionnaire and from the hospital records. Cancers were classified according to the Birch classification. The cases were analyzed according to the epidemiological profile, classification of cancer, and age-wise distribution using descriptive analysis.

Results:

In this study, out of 5221 cancer patients, TYAs accounted for 327 (6.26%) with 189 males and 138 females (M: F– 1.37:1). The maximum cases were seen in 25–30 years’ age group. Carcinoma was the most common malignancy (54.74%) with an increase from 19.56% in the 15–19 years’ age group to 64.82% in the 25–30-year-old patients.

Conclusion:

The present study gives a glimpse of the TYA cancers in the central India. More than half of the young cancer patients suffer from carcinomas with about half of these being head and neck cancers.
