The cancer care model recognizes the importance of surveillance strategies to detect recurrence or new malignancies early. Similarly, implementing structured postoperative monitoring programs for weight loss, nutritional status, metabolic parameters, and psychological health can facilitate the identification of potential complications or relapse in obesity management.

Long-term follow-up allows for timely interventions and continuous support, ensuring sustained success and improved quality of life for patients.

Bariatric surgery has emerged as an effective treatment option for severe obesity, providing substantial and sustainable weight loss, as well as significant improvements in comorbidities such as type 2 diabetes and hypertension.

However, adopting the oncology model in bariatric surgery offers a fresh perspective that goes beyond the conventional focus on weight loss alone.

The integration of personalized treatment approaches and the consideration of individual patient characteristics are fundamental aspects of the oncology model that can be applied to bariatric surgery.

Different types of bariatric surgery procedures, such as gastric bypass, sleeve gastrectomy, and biliopancreatic diversion, have varying mechanisms of action and physiological effects. Similarly, in the oncology model, the choice of treatment modalities, such as surgery, radiation therapy, or chemotherapy, is guided by the individual characteristics of the patient and the tumor.

By understanding the unique features of each patient's obesity, including metabolic profiles, gut hormone alterations, and genetic factors, bariatric surgery can be tailored to maximize its efficacy and safety. Additionally, both cancer treatment and bariatric surgery necessitate a multidisciplinary approach involving various healthcare professionals.

In the oncology model, the healthcare team collaborates to provide comprehensive care, considering not only the physical aspects but also the psychological, social, and nutritional aspects of the patient's well-being. Similarly, bariatric surgery programs can adopt a multidisciplinary approach that includes surgeons, endocrinologists, dietitians, psychologists, and physical therapists, among others, to address the holistic needs of individuals undergoing surgery and optimize long-term outcomes.

Applying the oncology model in bariatric surgery also highlights the importance of long-term monitoring and follow-up. Regular surveillance visits and assessments are crucial in cancer care to detect any recurrence or new tumors early. Similarly, in bariatric surgery, postoperative monitoring of weight loss, nutritional status, comorbidities, and psychological health can help identify potential complications, ensure patient compliance, and provide necessary interventions promptly.

By embracing the principles of the oncology model, bariatric surgery can evolve into a more personalized and patient-centered approach, leading to enhanced outcomes and improved quality of life for individuals with obesity.

A key aspect of the oncology model in obesity treatment is the adoption of a personalized approach in bariatric surgery.

Recognizing that obesity is a multifactorial condition with individual variations, tailoring the treatment plan to the specific needs and characteristics of each patient is crucial for optimizing outcomes.

The choice of the most suitable bariatric surgery procedure for an individual should consider several factors. Patient-related factors such as age, body mass index, presence of comorbidities, metabolic profile, and psychological well-being play a role in determining the appropriate surgical intervention.

For instance, individuals with uncontrolled type 2 diabetes may benefit more from metabolic procedures like gastric bypass, which has shown superior glycemic control compared to other procedures. In addition, the patient's preferences, expectations, and lifestyle factors should be considered to ensure treatment adherence and long-term success.

Understanding the patient's motivations, beliefs, and concerns can guide the selection of the most appropriate surgical option and facilitate shared decision-making between the healthcare team and the patient. Furthermore, preoperative evaluation is crucial in the personalized approach to bariatric surgery. Comprehensive assessments, including medical history, physical examination, nutritional evaluation, and psychological assessment, help identify potential risks and tailor the preoperative management plan accordingly.

This evaluation also allows for the identification of specific needs and potential barriers to success, enabling the development of targeted interventions and support strategies. By adopting a personalized approach in bariatric surgery, healthcare professionals can optimize patient outcomes and enhance patient satisfaction.
