The WHO has defined adolescent and young adults (AYAs) population as individuals diagnosed with cancer between the age group of 15–39 years. The Teenage and Young Adults Cancer Foundation has defined the age group to be between 15 and 29 years. The interest in AYA oncology arose when in the mid-90s, Bleyer observed that adolescent patients suffering from cancer had not benefitted from improvements in cancer therapy to the same extent as children.
Similar observations were made by NCI in 2006 in the AYA population when compared to children and older adults. Data showed that the patients belonging to the AYA subset reported little or no improvement in cancer survival. The shocking revelation was the low participation of these patients in clinical trials. They also enumerated in detail the further steps that need to be taken in the fields of epidemiology, disease biology, designing clinical trials, optimization of health services, and medical care. As the AYA population has great significance for all countries, special emphasis was also laid on the quality of life (QoL) of this population.
AYA oncology represents 4.3%–6.2% of the total nations cancer burden. The GLOBOCAN 2018 suggests that the annual burden of cancer cases in India is over a million with approximately 55,000 patients in the AYA population and 30,286 deaths.,
AYA cancer patients have unique challenges to the oncology teams around the world. AYA diagnosis has been classified into three subgroups. The first subgroup (15–19 years) is an extension of pediatric tumors such as hematological and bone tumors. The second epoch includes patients from the age group of 20–24 years where testicular and thyroids are more common and leukemia persists. From 25 to 39 years, the trend toward breast and colon rise, although they are far aggressive as compared to their counterparts in the elderly population.
When comparing the 5-year relative survival rates (1975–2014), there was an improvement of 20% in older adults, 25% in children, and 15% in the AYA population. However, the above numbers when reviewed should be taken with caution due to various reasons. First, there were a higher proportion of less aggressive malignancies with a high 5-year survival rates and thereby advancement in cancer therapy has led to lesser further benefit. Second, the lack of participation in clinical trials in this age group only complicates things.,,,,,
The reason for abandonment needs a special mention here as up to 38% of patients abandon their treatment due to various reasons, the highest being for hematological malignancies (28%).
Studies have focused on the reason for poor outcomes in this subset. These include differences in host and tumor biology, delayed diagnosis, lack of proper and specific guidelines leading to variation in treatment strategies, and poor compliance and adherence due to family and economic issues.,
The NCCN has issued detailed guidelines for discussing the various issues such as:
- Fertility preservation and contraception before starting anticancer therapy
- Financial issues
- QoL-addressing issues such as infections, pain, emesis, cachexia, cosmesis, cognition, emesis, hair loss, nutrition, weight loss, and myelosuppression which are unique to each modality and approach
- Late effects of each modality, including vital organ damage and secondary malignancies
- End-of-life care.
So, how are these issues relevant to a resource-starved country like ours?
As compared to the West, we have different challenges. We do not have enough data on disease burden, resources are not plentiful, the difference in biology (both tumor and host), and socioeconomic considerations.
India is at a demographic divide. The so-called “lost tribe” of oncology in India forming a major percentage of the Indian population even if it contributes to a small percentage, the numbers will be massive. With limited resources, there is bound to be disruption of physical and psychosocial fiber.
As compared to US databases, studies done in India have shown a marked difference in the malignancy. profile in India. Arora et al. and Kalyani et al., both based on population based cancer registries, have documented these differences.
The most common sites of malignancies in India include head and neck squamous cell carcinoma, breast, cervix, gastrointestinal carcinomas, lung, and hematolymphoid malignancies. Modifiable or partly modifiable factors such as alcohol, tobacco, and lower SES play a major role in these malignancies along with lax government policies. Hence, early intervention can be offered and lives at stake can be saved. The lack of centralized insurance alienates the family in society and also affects the other family members.,,,
Improving the outcomes in this subset of the population is a daunting task. There needs to be a holistic approach.
First, improvement in clinical trial enrolment as per the progress review group recommendation is required. The enrolment of AYA patients in 2006 stood at a mere 14%. Lack of insurance, poor representation of the older AYA population, and lack of pediatric centers were resulting in such a dismal situation., This population must be treated by pediatric oncologists as this subgroup does better when pediatric protocols are followed.
Second, the lack of health insurance is a big hindrance for these patients to undergo treatment for their generally aggressive diseases. Studies have shown that the majority of the Indian population does not have insurance coverage. Only a minority of these patients can afford the highly expensive cancer and supportive care. The state-sponsored hospitals which are often the less preferred options are overburdened, and with the one of the lowest percentage of GDP allocated to the health sector, the government-funded schemes fall short for appropriate treatment.
Third, interrupted social skills, educational and employment delays, psychosexual, and fertility issues result in delaying fiscal and emotional independence.
To conclude, AYA oncology is uncharted territory. In developing countries, good retrospective data to define the burden of disease are missing. The world is moving on toward prospective studies on this subset of cancer patients and we must do the same.
