HISTORICAL PERSPECTIVE
The evolution of neoadjuvant and adjuvant therapies in oncology reflects the growing understanding that surgery alone is often insufficient to achieve long-term survival, particularly for advanced cancers (Figure .
Once the primary mode of treatment, surgical resection has been transformed by the integration of multimodal approaches, including chemotherapy, radiation, and immunotherapy, which have collectively revolutionized patient outcomes.
Adjuvant therapy emerged in the midth 20 century as a pivotal advancement, with early clinical trials in breast cancer using cyclophosphamide, methotrexate, and fluorouracil (CMF) in the 1970s demonstrating significant survival benefits (Veronesi, et al.

The broader development of drug therapies and innovations in molecular oncology established adjuvant therapy as a cornerstone of cancer care.
Neoadjuvant later, aimed to improve surgical outcomes by shrinking tumors preoperatively.
Its early success in rectal cancer, where chemotherapy and radiotherapy improved local control, demonstrated the value of reducing tumor size to enhance surgical (Bosset.
Neoadjuvant chemotherapy in breast cancer also increased breast-conserving surgeries, showing its importance in reducing the need for radical procedures and optimizing patient outcomes (Hortobagyi, et al.

Neoadjuvant performed after preoperative therapy, have transformed cancer treatment by improving the resectability of tumors and enhancing overall These focus on reducing tumor size, achieving better surgical margins, and lowering the risk of distant By integrating surgery with neoadjuvant therapies, such as chemotherapy, radiation, and immunotherapy, this multimodal approach addresses both the primary tumor and therapeutic outcomes.
One of the critical benefits of neoadjuvant interventions is tumor downstaging.
By shrinking tumors preoperatively, previously inoperable tumors may become resectable, improving the chances of complete tumor removal and enhancing the patientAos prognosis.
Additionally, the effectiveness of subsequent adjuvant treatments by reducing tumor burden and exposing residual cancer cells to systemic treatments like chemotherapy or radiation (Versluis, et al.
, 2.
Multiple clinical trials and case studies have underscored the effectiveness of neoadjuvant approaches.
For example, in breast cancer, neoadjuvant chemotherapy has increased the rates of breast-conserving surgeries, reducing the need for mastectomies and improving cosmetic outcomes (OAoDonnell, et al.
, 2.
Similarly, in rectal cancer, preoperative chemoradiotherapy has led to significant improvements in local control and overall survival (Keung, et al.

The systemic benefits of neoadjuvant therapy extend beyond surgery (Figure .
addressing micrometastatic disease early, these therapies reduce the risk of recurrence and metastasis, significantly improving long-term survival rates (Siegel, et al.

ADJUVANT SURGICAL INTERVENTIONS
Adjuvant surgical interventions play a pivotal role in reducing cancer recurrence by eliminating residual microscopic disease that post-surgery.
These enhance long-term survival and minimize metastasis risks, particularly in high-risk patients.
Adjuvant therapies complement surgery by targeting undetected cancer cells, reducing recurrence and improving patient prognosis.
For example, in muscle-invasive bladder cancer (MIBC), adjuvant chemotherapy and immunotherapy following radical cystectomy have improved disease-free survival rates (Holzbeierlein, et al.
, 2.
Additionally, adjuvant precision surgery helps optimize patient outcomes by ensuring targeted removal of high-risk residual disease, minimizing the need for aggressive systemic The integration of adjuvant moleculartargeted therapies has significantly advanced cancer treatment.
In ALK-positive non-small cell lung cancer (NSCLC), the FDA-approved adjuvant therapy alectinib has outperformed disease-free post-resection (FDA Approves Alectinib for ALK-Positive Lung Cancer, 2.
These findings demonstrate how adjuvant therapy not only extends survival but also prevents early metastatic spread, reinforcing the importance of post-surgical interventions in highrisk molecular subtypes of cancer.
However, the effectiveness of adjuvant therapy is influenced by several real-world overtreatment concerns, and patient selection issues.
In prostate cancer, the timing of adjuvant androgendeprivation therapy (ADT) post-surgery remains debated, as early ADT can delay metastasis but may not always improve survival (Current Controversies in the Management of Biochemical Failure in Prostate Cancer, n.
Similarly, adjuvant treatment intensity must be carefully tailored to patient risk profiles, as some patients may achieve durable remission with surgery alone, avoiding unnecessary toxicity from additional systemic therapies.
Future research should focus on identifying biomarkers that predict adjuvant therapy response, allowing for a more selective and individualized approach to postoperative cancer management.
COMBINATION OF NEOADJUVANT AND
ADJUVANT APPROACHES
Combining neoadjuvant and adjuvant therapies with surgical interventions has emerged as a powerful strategy to maximize treatment efficacy by targeting both the primary tumor and micrometastatic disease.
Neoadjuvant therapies improving the likelihood of complete resection, while adjuvant therapies target any remaining microscopic disease postoperatively, reducing recurrence risk.
This multimodal approach has demonstrated superior survival benefits across multiple cancer types.
One of the critical aspects of NAC AC sequencing is tumor biology-driven treatment In breast cancer, neoadjuvant chemotherapy allows for tumor downstaging, enabling breast-conserving surgery instead of mastectomy, preserving tissue and improving Indonesian Journal of Cancer Chemoprevention.

Similarly, in rectal cancer, neoadjuvant chemoradiation followed by surgery and adjuvant chemotherapy has shown significant improvements in local control and recurrence reduction (Quezada-Diaz & Smith.
The ability to integrate NAC and AC into a structured protocol enhances long-term survival while minimizing treatment morbidity.
Evidence from large-scale clinical trials further validates the NAC AC approach.
In NSCLC, the combination of neoadjuvant immunotherapy with surgery has demonstrated improved overall survival by inducing tumor regression and activating immune responses to residual disease (Kang, et al.
, 2.
Colorectal cancer patients treated with neoadjuvant chemoradiation followed by surgery and adjuvant chemotherapy experience a significant increase in 5-year survival rates (Smith, et al.
, 2.
Furthermore, in pancreatic cancer, the sequential use of NAC and AC has resulted in better resectability rates and prolonged disease-free survival compared to surgery-first approaches (Conroy, 2.
Despite the advantages, several challenges must be addressed in optimizing NAC AC treatment pathways.
Patient selection remains a major hurdle, as not all cancers respond uniformly to neoadjuvant therapy, and over-treatment risks must be carefully considered.
Additionally, the timing of surgery post-NAC is crucial, as delays beyond the optimal window can allow for tumor progression, potentially negating preoperative Moreover, the long-term impact of combining aggressive neoadjuvant and adjuvant regimens on patient quality of life requires further investigation, as cumulative toxicity may outweigh survival gains in some cases.

INNOVATIVE
TECHNIQUES
ONCOLOGICAL SURGERY
Recent advances in oncological surgery have significantly enhanced the precision and efficacy of both neoadjuvant and adjuvant interventions, helping improve patient outcomes.
One of the most notable developments is the widespread use of minimally invasive surgery (MIS) and robotic-assisted techniques.
These innovations reduce postoperative complications by minimizing muscle damage, blood loss, and recovery times.
Robotic-assisted surgeries, such as those performed with the da Vinci Surgical System, offer surgeons greater precision, dexterity, and control, particularly in complex oncological procedures (Minimally Invasive Surgery | Methodist Healthcare, n.
MIS techniques, including laparoscopic and thoracoscopic surgeries, are now standard for cancers of the gastrointestinal tract, lungs, and gynecological systems.
These methods provide several benefits, such as reduced postoperative pain, faster recovery, and shorter hospital stays.
For example, robotic-assisted surgeries allow for more accurate dissections and anastomoses, improving outcomes in colorectal and gynecological cancers (Methodist Healthcare, 2024.
Laina, et al.
, 2.
Advances in imaging and navigation technologies have further refined surgical precision.
Intraoperative imaging techniques, such as MRI and CT scans, enable surgeons to visualize tumors and critical structures in real-time, minimizing damage to healthy tissue.
These image-guided techniques are especially beneficial in delicate procedures, such as brain and liver surgeries, where precision is paramount.
Additionally, augmented reality (AR) and virtual reality (VR) technologies are being integrated into surgical practice, enabling surgeons to superimpose digital images onto the surgical field for enhanced spatial awareness and accuracy (Shen, et al.
, 2.
A breakthrough in precision surgery involves the use of genomic and molecular profiling to tailor surgical plans and adjunct therapies to individual tumor characteristics.
Fluorescenceguided surgery (FGS), where cancer cells are made to glow under specific lights, is an example of how technology is helping surgeons achieve more complete resections, reducing residual disease and improving long-term outcomes (Nema & Vachhani, 2.
These innovations underscore the shift towards more personalized surgical care, where treatments are specifically tailored to each patientAos unique tumor biology.
Robotic systems incorporating artificial intelligence (AI) are also transforming surgical AI-driven systems assist with tasks such as autonomous camera positioning, instrument tracking, and even performing certain procedures These innovations reduce the cognitive load on surgeons, allowing for more consistent and efficient surgeries.
For example.
AI has been successfully employed in autonomous suturing and anastomosis, improving the speed and accuracy of these tasks (Miao, et al.
, 2017.
Feng, et , 2.
The integration of these innovative techniques into oncological surgery represents a significant leap forward, promising better outcomes for cancer patients through enhanced precision, reduced complications, and quicker recovery These advancements, when combined with neoadjuvant and adjuvant therapies, create a comprehensive, multimodal approach to cancer care that maximizes therapeutic benefit.
CHALLENGES AND CONSIDERATIONS
While technological advancements in oncological surgery have improved patient outcomes, several challenges persist, particularly in the context of integrating multimodal therapies.
Minimally invasive and robotic-assisted surgeries have transformed the surgical landscape by reducing postoperative pain, shortening hospital stays, and expediting recovery times.
However.
Indonesian Journal of Cancer Chemoprevention.
October 2024 ISSN: 2088Ae0197 e-ISSN: 2355-8989 these techniques require extensive training and can be cost-prohibitive, limiting accessibility in certain Additionally, despite their benefits, the increased reliance on technology introduces new potential complications, such as system malfunctions or the need for surgeon expertise in handling complex robotic systems (Negrut, et al.
, 2.
The integration of advanced imaging and navigation technologies, while improving surgical precision, presents its own set of challenges.
High-resolution imaging techniques like MRI and CT scans, when combined with intraoperative navigation, enhance the surgeonAos ability to locate tumors and assess margins accurately.
However, the availability and cost of these technologies can restrict their use, particularly in resource-limited environments, further complicating the adoption of precision surgical approaches (Caruso, et al.
, 2.
Moreover, the rise of precision surgery, which tailors interventions based on molecular and genetic tumor profiles, holds great promise for improving outcomes.
However, it also raises concerns about over-treatment and costeffectiveness.
While precision surgery has been shown to improve survival and reduce recurrence, it requires sophisticated diagnostic tools and multidisciplinary collaboration, adding layers of complexity to cancer care.
This approach also overtreatment, particularly in patients with indolent cancers, where aggressive surgical interventions may not significantly improve outcomes (Sanglier, et al.
, 2.
Postoperative management, especially acute pain management, remains a significant Effective pain management is critical to preventing long-term complications, such as persistent postsurgical pain, which can negatively affect recovery and increase healthcare costs (Small & Laycock, 2.
The timing and sequencing of neoadjuvant and adjuvant therapies with surgical interventions also require careful consideration to ensure the maximal therapeutic benefit while minimizing adverse effects.
Additionally, patient-specific factors, such as comorbidities and genetic predispositions, are essential to consider when planning surgical Personalized treatment strategies that account for these factors can help mitigate risks and improve outcomes.
For example, patients with preexisting conditions may require tailored perioperative care protocols and individualized pain management strategies to optimize recovery and minimize complications (Khazov, et al.
, 2.
Accessibility to advanced care is another challenge in resource-limited settings, where innovations may not be as readily available, limiting the potential benefits of advanced multimodal therapies.
CASE STUDIES AND CLINICAL TRIALS
The efficacy of integrating neoadjuvant and adjuvant surgical interventions is best demonstrated through large-scale clinical trials and illustrative case studies, which provide critical evidence supporting the strategic application of these treatments in oncology.
These examples showcase how the multimodal approach combining surgery with systemic therapies can significantly improve patient outcomes.
Clinical trials are essential in establishing optimal treatment protocols for neoadjuvant and adjuvant therapies.
For instance, the KEYNOTE-522 trial demonstrated the significant benefit of combining pembrolizumab with chemotherapy for triple-negative breast cancer, showing improved pathological complete response rates (Schmid, et al.
, 2.
Similarly, the CheckMate 816 trial highlighted the value of neoadjuvant nivolumab combined with chemotherapy in resectable nonsmall cell lung cancer (NSCLC), leading to improved event-free survival (Forde, et al.
, 2.
These trials underscore the importance of integrating immunotherapy and chemotherapy in enhancing outcomes, particularly for cancers with limited surgical options, while optimizing the sequencing of multimodal therapies.

Case studies offer further insight into the practical application of these strategies.
For example, the use of neoadjuvant chemoradiation in rectal cancer has been shown to downstage tumors, facilitating sphincter-preserving surgeries and improving quality of life outcomes (Glynne-Jones, et al.
, 2.
Similarly, in esophageal cancer, neoadjuvant chemotherapy significantly improved both resectability and survival rates, underscoring its value in treatment protocols for difficult-to-treat cancers (Shapiro, et al.
, 2.
These examples highlight how combining systemic therapies with surgery can optimize patient outcomes, improve resectability, and minimize the need for more extensive surgical interventions.
These case studies and trials underscore the importance of evidence-based, individualized approaches to neoadjuvant and adjuvant treatments.
