Dimensioni preoperatorie e patologiche nel cancro al seno: uno studio prospettico
Concordanza tra valutazioni preoperatorie e misurazioni delle dimensioni patologiche nel cancro al seno: uno studio osservazionale prospettico
Breast cancer, the most prevalent malignancy among women globally, is increasing in incidence. While non-metastatic breast cancer requires surgery, determining the optimal extent of resection remains challenging. Inadequate resection margins necessitate reoperation, leading to increased psychological stress, costs, and potentially compromised cosmetic outcomes and prognosis.
Accurate preoperative assessment of resection extent is crucial and involves various factors, including imaging studies, physical examinations, tumor molecular subtypes, and intraductal carcinoma components. This prospective observational study aims to identify and integrate multiple predictive factors to enhance surgical planning and minimize reoperation rates in breast cancer patients.

Descrizione dettagliata
Breast cancer is the most prevalent malignancy among women globally, leading to surgical interventions for non-metastatic cases. While breast cancer generally has a favorable prognosis, achieving negative resection margins at initial surgery is crucial for optimal outcomes. The challenge associated with accurately predicting the extent of resection preoperatively, as failure to secure clear margins may necessitate further resection or total mastectomy, resulting in increased psychological stress, higher healthcare costs, compromised cosmetic results, and potential negative impacts on long-term prognosis and quality of life. Many factors contribute to predicting the optimal resection extent, including imaging studies, physical examination findings, tumor molecular subtypes, presence and extent of intraductal carcinoma components, etc. Despite the availability of these predictive factors, their integration and practical application in clinical decision-making remain challenging. This prospective observational study aims to address this gap by analyzing the interplay of these factors in real-world clinical settings, with the primary objective of deriving an integrated predictive model to guide surgeons in determining the optimal extent of resection preoperatively.

Concordance rate by size discordance (5mm) To evaluate the concordance between preoperative tumor size assessments and pathologic measurements in the subgroup of patients with ductal carcinoma in situ (DCIS)
Lasso di tempo: Within 30 days after surgery
|
To assess the concordance between preoperative tumor size assessments made by surgeons and the actual tumor size determined by pathologic analysis following surgical resection in patients with breast cancer. A difference of 5mm or more between preoperative and pathologic measurements is defined as discordance. |
Within 30 days after surgery

Concordance rate and discrepancy factor in ductal carcinoma in situ (DCIS) subgroup
Lasso di tempo: Within 30 days after surgery
|
To evaluate the concordance between preoperative tumor size assessments and pathologic measurements in the subgroup of patients with ductal carcinoma in situ (DCIS). |
Within 30 days after surgery
|
|
Concordance rate and discrepancy factor in neoadjuvant systemic therapy subgroup
Lasso di tempo: Within 30 days after surgery
|
To assess the concordance between preoperative tumor size assessments and pathologic measurements in the subgroup of patients who received neoadjuvant systemic therapy |
Within 30 days after surgery

Proportion of surgical method change: rates of unnecessary total mastectomy
Lasso di tempo: Within 30 days after surgery
|
To determine the rate of change in surgical method (e.g., from lumpectomy to mastectomy, nipple-sparing to skin-sparing, or vice versa) based on discrepancies between preoperative tumor size assessments and pathologic measurements. This involves collecting the initial surgical method plan from the surgeon before the surgery and, after confirming the pathological size post-surgery, collecting the final surgical method deemed feasible for the patient from the surgeon. |
Within 30 days after surgery
|
|
Factors requiring MRI: factors associated with size discrepancy between MRI and mammography (with/without Breast ultrasonography)
Lasso di tempo: Within 30 days after surgery
|
To determine the associated factors contributing to size discrepancies between mammography (with or without breast ultrasonography) and MRI. For analyzing the clinical factors that necessitate the use of MRI to predict the pathologic tumor size. |
Within 30 days after surgery
|
|
Rate of recurrence within 1-year after breast surgery
Lasso di tempo: Within 1 year after enroll
|
The proportion of patients who develop new malignant lesions during the follow-up period within 1 year after breast surgery. |
